and the supporting device is provided with a feeding chute for discharging the ejected nails out of the equipment.

When the invention is used: when the chain cutting device is used, a chain needing to be cut off is installed on the first driving wheel, then the first driving wheel is externally connected with power, and the first driving wheel rotates to drive the chain to move. Meanwhile, the first driving wheel can drive a third driving wheel meshed with the first driving wheel to rotate, the third driving wheel can drive a third bevel gear coaxially arranged with the third driving wheel to rotate, the third bevel gear can drive a first bevel gear meshed with the third bevel gear to mesh (the first bevel gear and the third bevel gear are meshed in an initial position), the first bevel gear can drive a sleeve fixedly connected with the first bevel gear to rotate, the sleeve can drive an inner cylinder vertically and slidably connected with the sleeve to rotate, and the inner cylinder rotatably connected to the supporting device rotates; because the threaded rod is vertically and slidably connected with the limiting plate fixedly connected to the supporting device, the threaded rod connected with the inner cylinder in a threaded mode can be driven to vertically move downwards by the rotation of the inner cylinder. The threaded rod moves vertically downwards to drive the pressing rod to move downwards, the pressing rod moves downwards to extrude the driving shaft to move downwards, when the driving shaft moves downwards, external teeth on the driving shaft can be clamped with the through grooves in the non-all gears, when the driving shaft is clamped with the non-all gears, the first driving wheel can rotate synchronously with the non-all gears, and the non-all gears can drive the bidirectional rack frame which is meshed with the non-all gears to move. The bidirectional rack frame moves to drive the first rack to move, the first rack moves to drive the polishing platform connected with the first rack to move synchronously, the polishing platform moves along the first sliding groove under the action of the first rack, and the polishing platform vertically moves downwards relative to the nails in the chain right below the polishing platform, so that the grinding disc on the polishing platform can vertically move downwards relative to the nails, the salient points of the nails are polished to be flat, and preparation is made for next ejecting chains of the nails.

In the process of polishing the willow nail, the first rack moves to drive the second gear meshed with the first rack to rotate, and the second gear rotates to drive the second rack also meshed with the second rack to move, so that the first rack and the second rack are close to each other. The second rack moves to drive the jacking table which is connected with the second rack in a sliding mode to move along the third sliding groove, the jacking table moves along the third sliding groove and finally moves right above the polishing table (at the moment, the axes of the polished willow nail of the polishing disc and the axis of the polished willow post are overlapped), and therefore the top post can accurately position the polished willow nail.

When the grinding table moves to the limit distance along the first chute, the bidirectional rack can also drive the inclined plate to synchronously move with the inclined plate fixedly connected with the bidirectional rack, in the process, the inclined plate can be separated from a separation blade fixedly connected to the sleeve under the drive of the bidirectional rack, the sleeve can move downwards under the action of elastic force, so the first bevel gear can be separated from the third bevel gear, the second bevel gear returns to the third bevel gear to be meshed, at the moment, the second bevel gear can drive the sleeve to reversely rotate under the drive of the third bevel gear, the sleeve can drive the inner cylinder to reversely rotate relative to the vertical sliding connection, the inner cylinder can drive the threaded rod to vertically move upwards, the threaded rod can drive the pressure rod fixedly connected with the threaded rod to synchronously move upwards when vertically moving upwards, and the driving shaft can also gradually move upwards under the action of elastic force (the process corresponding to the bidirectional rack to reversely move). The bidirectional rack reverse motion can drive the grinding table to move reversely, the grinding disc on the grinding table is located at the lowest point at the moment, the first sliding plate which is connected in the second sliding groove in a sliding mode in the reset process of the grinding disc can move along the first return groove under the limitation of the second rotating plate (the first sliding plate can move along the first progress groove and pass through the second rotating plate after being jacked up, and the second rotating plate can reset under the action of gravity), and the grinding shaft can vertically move upwards relative to the grinding table under the driving of the first sliding plate because the first sliding plate is rotationally connected with the grinding shaft, so that the grinding disc is driven to vertically move upwards, and further the grinding disc is prevented from interfering with nails on a chain. When the grinding table moves to the initial position, the first sliding plate which is connected in the limiting rod in a transverse sliding mode can be pulled to the initial position by the limiting rod under the action of elastic force. What goes on here simultaneously is that the roof pressure platform can carry out reverse synchronous motion with the platform of polishing, and the roof pressure platform can move down gradually along the in-process of third spout reverse motion, and the fore-set of elastic sliding connection on the roof pressure platform can move down gradually under the extrusion of stopper, until the fore-set is extruded in the chain after being polished to with the ejecting chain of the willow nail in the chain, the willow nail that is ejected can be followed the silo and dropped out from equipment. Meanwhile, the top column can lose the limit of the limiting block at this time, and the top column can enter the second return groove under the action of elastic force, so that the chain is not prevented from moving forwards normally. Thereby completing the cutting of the chain once.

When accomplishing the chain and cutting off, the threaded rod will drive the depression bar and remove to and the driving shaft between just contactless position, and at this moment, the driving shaft breaks away from the block with non-full gear under the effect of elastic force, and non-full gear will unable and first drive wheel synchronous revolution.

the supporting device 1 is provided with a switching mechanism which can be matched with the first driving wheel 3 to switch the motion directions of the grinding mechanism and the cutting mechanism;

the supporting device 1 is provided with a feeding chute 19 for discharging the ejected nails out of the equipment; an external driving device is arranged on the first driving wheel 3.

When in work: a chain 2 to be cut is arranged on a supporting device 1, the chain 2 is meshed with a first driving wheel 3, then an external driving device on the first driving wheel 3 drives the chain 3 to rotate, and the first driving wheel 3 rotates to drive the chain 2 to move. Meanwhile, the first driving wheel 3 rotates to drive a third driving wheel 33 meshed with the first driving wheel to rotate, the third driving wheel 33 rotates to drive a third bevel gear 32 coaxially arranged with the third driving wheel to rotate, the third bevel gear 32 rotates to drive a first bevel gear 4 meshed with the third bevel gear to mesh with the third bevel gear (the first bevel gear 4 is meshed with the third bevel gear 32 at the initial position), the first bevel gear 4 rotates to drive a sleeve 35 fixedly connected with the first bevel gear to rotate, the sleeve 35 rotates to drive an inner cylinder 36 vertically and slidably connected with the sleeve to rotate, and the inner cylinder 36 rotatably connected to the supporting device 1 rotates; since the threaded rod 6 is vertically slidably connected to the limit plate 7 fixedly connected to the support device 1, the rotation of the inner cylinder 36 drives the threaded rod 6, which is in threaded connection therewith, to move vertically downward. The threaded rod 6 moves vertically downwards to drive the pressing rod 34 fixedly connected with the threaded rod to move downwards, the pressing rod 34 moves downwards to extrude the driving shaft 10 to move downwards, when the driving shaft 10 moves downwards, external teeth on the driving shaft 10 can be clamped with the through groove in the non-all gear 16, when the driving shaft 10 is clamped with the non-all gear 16, the first driving wheel 3 can rotate synchronously with the non-all gear 16, and the non-all gear 16 rotates to drive the bidirectional rack 9 meshed with the non-all gear to move. The bidirectional rack 9 moves to drive the first rack 20 to move, the first rack 20 moves to drive the polishing table 27 connected with the first rack in a sliding mode to move synchronously, the polishing table 27 moves along the first sliding groove 11 under the action of the first rack 20, the polishing table 27 vertically moves downwards relative to the nails in the chain 2 right below the polishing table 27, so that the grinding disc 26 on the polishing table 27 can vertically move downwards relative to the nails, the salient points of the nails are polished to be flat, and preparation is made for ejecting the nails out of the chain 2 next.

During the process of polishing the spike, since the first rack 20 moves to drive the second gear 22 engaged therewith to rotate, the second gear 22 rotates to drive the second rack 21 also engaged therewith to move, so that the first rack 20 and the second rack 21 approach each other. The second rack 21 moves to drive the pressing table 23 connected with the second rack in a sliding manner to move along the third sliding groove 13, and the pressing table 23 moves along the third sliding groove 13 and finally moves right above the polishing table 27 (at this time, the axes of the polished nails by the polishing disc 26 and the top pillar 15 are overlapped), so that the top pillar 15 can accurately position the polished nails.

When the grinding table 27 moves to a limit distance along the first chute 11, the bidirectional rack 9 also drives the inclined plate 17 fixedly connected with the bidirectional rack to move synchronously, in the process, the inclined plate 17 is separated from the baffle plate 18 fixedly connected to the sleeve 35 under the drive of the bidirectional rack 9, the sleeve 35 moves downwards under the action of elastic force, the first bevel gear 4 will disengage from the third bevel gear 32 and the second bevel gear 5 will come back into engagement with the third bevel gear 32, at which point, the second bevel gear 5 can drive the sleeve 35 to rotate reversely under the driving of the third bevel gear 32, the sleeve 35 rotates reversely to drive the inner cylinder 36 connected with the sleeve in a vertical sliding mode to rotate reversely, the inner cylinder 36 rotates reversely to drive the threaded rod 6 to move upwards vertically, the threaded rod 6 can drive the pressing rod 34 connected with the threaded rod to move upwards synchronously during vertical upwards movement, and the driving shaft 10 can also move upwards gradually under the action of elastic force (the process corresponds to the process of reverse movement of the bidirectional rack 9). The grinding table 27 is driven to move reversely by the reverse movement of the bidirectional rack 9, since the grinding disc 26 on the grinding table 27 is located at the lowest point at this time, the first sliding plate 24 slidably connected in the second sliding groove 12 in the resetting process of the grinding disc 26 moves along the first sliding groove 12-2 under the restriction of the second rotating plate 30 (the first sliding plate 24 moves along the first progressing groove 12-1 and passes through the second rotating plate 30 in the feeding process, and the second rotating plate 30 resets under the action of gravity after being jacked up), and because the first sliding plate 24 is rotatably connected with the grinding shaft 31, the grinding shaft 31 vertically moves upward relative to the grinding table 27 under the driving of the first sliding plate 24, so as to drive the grinding disc 26 to vertically move upward, and further prevent the grinding disc 26 from interfering with the nails on the chain 2. When the grinding table 27 is moved to the initial position, the first slide plate 24, which is laterally slidably connected in the stopper rod 28, is pulled to the initial position by the stopper rod 28 under the influence of elastic force. Meanwhile, the jacking table 23 and the polishing table 27 perform reverse synchronous movement, the jacking table 23 gradually moves downwards in the process of reverse movement along the third sliding chute 13, the ejection column 15 which is elastically and slidably connected to the jacking table 23 gradually moves downwards under the extrusion of the limiting block 4 until the ejection column 15 is extruded into the polished chain 2, so that the nails in the chain 2 are ejected out of the chain 2, and the ejected nails fall out of the equipment along the blanking chute 19. Meanwhile, the top pillar 15 loses the limit of the limit block 4 at this time, and the top pillar 15 enters the second return groove 14-1 under the action of elasticity, so that the chain 2 is not prevented from normally moving forwards. Thereby completing the cutting of the chain 2 once.

Therefore, the non-full gear 16 is reset after rotating for one circle, the bidirectional rack 9 is also reset under the driving of the non-full gear 16, the inclined plate 17 is reset under the driving of the bidirectional rack 9, the blocking piece 18 is jacked up by the inclined plate 17 again, the first transmission wheel 3 is meshed with the third transmission wheel 33, the second gear 22 is separated from the third transmission wheel 33, and the next round of cutting is started.

As a further aspect of the present invention, the polishing sheet is fixedly connected to the polishing shaft 31 by a screw and a nut.

The working principle is as follows: when the chain cutting device is used, a chain 2 needing to be cut off is arranged on the first driving wheel 3, then power is externally connected to the first driving wheel 3, and the first driving wheel 3 rotates to drive the chain 2 to move. Meanwhile, the first driving wheel 3 rotates to drive a third driving wheel 33 meshed with the first driving wheel to rotate, the third driving wheel 33 rotates to drive a third bevel gear 32 coaxially arranged with the third driving wheel to rotate, the third bevel gear 32 rotates to drive a first bevel gear 4 meshed with the third bevel gear to mesh with the third bevel gear (the first bevel gear 4 is meshed with the third bevel gear 32 at the initial position), the first bevel gear 4 rotates to drive a sleeve 35 fixedly connected with the first bevel gear to rotate, the sleeve 35 rotates to drive an inner cylinder 36 vertically and slidably connected with the sleeve to rotate, and the inner cylinder 36 rotatably connected to the supporting device 1 rotates; since the threaded rod 6 is vertically slidably connected to the limit plate 7 fixedly connected to the support device 1, the rotation of the inner cylinder 36 drives the threaded rod 6, which is in threaded connection therewith, to move vertically downward. The threaded rod 6 moves vertically downwards to drive the pressing rod 34 fixedly connected with the threaded rod to move downwards, the pressing rod 34 moves downwards to extrude the driving shaft 10 to move downwards, when the driving shaft 10 moves downwards, external teeth on the driving shaft 10 can be clamped with the through groove in the non-all gear 16, when the driving shaft 10 is clamped with the non-all gear 16, the first driving wheel 3 can rotate synchronously with the non-all gear 16, and the non-all gear 16 rotates to drive the bidirectional rack 9 meshed with the non-all gear to move. The bidirectional rack 9 moves to drive the first rack 20 to move, the first rack 20 moves to drive the polishing table 27 connected with the first rack in a sliding mode to move synchronously, the polishing table 27 moves along the first sliding groove 11 under the action of the first rack 20, the polishing table 27 vertically moves downwards relative to the nails in the chain 2 right below the polishing table 27, so that the grinding disc 26 on the polishing table 27 can vertically move downwards relative to the nails, the salient points of the nails are polished to be flat, and preparation is made for ejecting the nails out of the chain 2 next.

During the process of polishing the spike, since the first rack 20 moves to drive the second gear 22 engaged therewith to rotate, the second gear 22 rotates to drive the second rack 21 also engaged therewith to move, so that the first rack 20 and the second rack 21 approach each other. The second rack 21 moves to drive the pressing table 23 connected with the second rack in a sliding manner to move along the third sliding groove 13, and the pressing table 23 moves along the third sliding groove 13 and finally moves right above the polishing table 27 (at this time, the axes of the polished nails by the polishing disc 26 and the top pillar 15 are overlapped), so that the top pillar 15 can accurately position the polished nails.

When the grinding table 27 moves to a limit distance along the first chute 11, the bidirectional rack 9 also drives the inclined plate 17 fixedly connected with the bidirectional rack to move synchronously, in the process, the inclined plate 17 is separated from the baffle plate 18 fixedly connected to the sleeve 35 under the drive of the bidirectional rack 9, the sleeve 35 moves downwards under the action of elastic force, the first bevel gear 4 will disengage from the third bevel gear 32 and the second bevel gear 5 will come back into engagement with the third bevel gear 32, at which point, the second bevel gear 5 can drive the sleeve 35 to rotate reversely under the driving of the third bevel gear 32, the sleeve 35 rotates reversely to drive the inner cylinder 36 connected with the sleeve in a vertical sliding mode to rotate reversely, the inner cylinder 36 rotates reversely to drive the threaded rod 6 to move upwards vertically, the threaded rod 6 can drive the pressing rod 34 connected with the threaded rod to move upwards synchronously during vertical upwards movement, and the driving shaft 10 can also move upwards gradually under the action of elastic force (the process corresponds to the process of reverse movement of the bidirectional rack 9). The grinding table 27 is driven to move reversely by the reverse movement of the bidirectional rack 9, since the grinding disc 26 on the grinding table 27 is located at the lowest point at this time, the first sliding plate 24 slidably connected in the second sliding groove 12 in the resetting process of the grinding disc 26 moves along the first sliding groove 12-2 under the restriction of the second rotating plate 30 (the first sliding plate 24 moves along the first progressing groove 12-1 and passes through the second rotating plate 30 in the feeding process, and the second rotating plate 30 resets under the action of gravity after being jacked up), and because the first sliding plate 24 is rotatably connected with the grinding shaft 31, the grinding shaft 31 vertically moves upward relative to the grinding table 27 under the driving of the first sliding plate 24, so as to drive the grinding disc 26 to vertically move upward, and further prevent the grinding disc 26 from interfering with the nails on the chain 2. When the grinding table 27 is moved to the initial position, the first slide plate 24, which is laterally slidably connected in the stopper rod 28, is pulled to the initial position by the stopper rod 28 under the influence of elastic force. Meanwhile, the jacking table 23 and the polishing table 27 perform reverse synchronous movement, the jacking table 23 gradually moves downwards in the process of reverse movement along the third sliding chute 13, the ejection column 15 which is elastically and slidably connected to the jacking table 23 gradually moves downwards under the extrusion of the limiting block 4 until the ejection column 15 is extruded into the polished chain 2, so that the nails in the chain 2 are ejected out of the chain 2, and the ejected nails fall out of the equipment along the blanking chute 19. Meanwhile, the top pillar 15 loses the limit of the limit block 4 at this time, and the top pillar 15 enters the second return groove 14-1 under the action of elasticity, so that the chain 2 is not prevented from normally moving forwards. Thereby completing the cutting of the chain 2 once.

When the chain 2 is cut off, the threaded rod 6 drives the pressure rod 34 to move to a position which is just not contacted with the driving shaft 10, at the moment, the driving shaft 10 is disengaged from the non-full gear 16 under the action of elastic force, and the non-full gear 16 cannot rotate synchronously with the first transmission wheel 3. Therefore, the non-full gear 16 is reset after rotating for one circle, the bidirectional rack 9 is also reset under the driving of the non-full gear 16, the inclined plate 17 is reset under the driving of the bidirectional rack 9, the blocking piece 18 is jacked up by the inclined plate 17 again, the first transmission wheel 3 is meshed with the third transmission wheel 33, the second gear 22 is separated from the third transmission wheel 33, and the next round of cutting is started.
