The driving gear 51 is fixedly connected to the first rotating shaft 50, and the one-way gear 52 can only rotate around one direction relative to the first rotating shaft 50; the driving plate 6 is provided with a rack surface 60 used for being meshed with the driving gear 51; when the rack surface 60 is meshed with the driving gear 51 from top to bottom, the one-way gear 52 rotates relative to the first rotating shaft 50; when the rack face 60 is engaged with the driving gear 51 from bottom to top, the first rotating shaft 50 drives the one-way gear 52 to rotate together and drives the push plate 56 to move towards the discharging end of the pressing table 4.

According to the automatic material discharging device, the pushing mechanism 5 can be driven to act through the upward reset movement of the pressing head 1, and the pressed material 8 on the pressing table board 4 is pushed to the material discharging end, so that automatic material discharging is realized, convenience and rapidness are realized, the operation is compact, and the efficiency can be improved; two sets of operation actions can be realized through one driving source, return power of the upward reset of the pressure head 1 is used as driving force of the pushing mechanism 5, the return power of the pressure head 1 is fully utilized, and energy consumption is reduced. The following is a more specific example.

In this embodiment, the driving plate 6 is fixed to the side of the pressure head 1 through a connecting plate 62, the pushing mechanism 5 further includes a second rotating shaft 55 rotatably connected to the inner wall of the mounting groove 30, and the driven gear 54 is disposed on the second rotating shaft 55; the first rotating shaft 50 is rotatably coupled to the inner wall of the mounting groove 30. A driving slot 31 for the driving plate 6 to be inserted in a matching manner is further formed in the inner wall of the rear end of the mounting groove 30, and the driving gear 51 is located on the side of the driving slot 31; when the driving plate 6 is inserted into the driving slot 31, the rack face 60 is engaged with the pinion gear 51.

Wherein, in a preferred embodiment, the bottom end of the rack face 60 is provided with an arc-shaped guide face 61 that is inclined away from the pinion gear 51. The arrangement of the arc-shaped guide surface 61 can not only facilitate the smooth insertion of the driving plate 6 into the driving slot 31, but also guide the engagement of the rack surface 60 and the driving gear 51, thereby facilitating the smooth operation of the mechanism.

Wherein, the hold-in range 53 is last to be connected with connecting strut 57, and push pedal 56 rigid coupling is in connecting strut 57 upper end, and the height of push pedal 56 bottom surface is higher than compressing tightly mesa 4, and push pedal 56 can be in compressing tightly the mesa 4 top reciprocating motion to push out the material 8 after compressing tightly on the mesa 4, and reset again.

Wherein, the inner wall of the rear end of the mounting groove 30 is further fixedly connected with a mounting block 32, the first rotating shaft 50 can rotatably penetrate through the mounting block 32, and the side wall of the mounting block 32 facing to one side of the pressing table-board 4 is provided with a spring hole 33; a limit ejector rod 34 with the outer end extending out of the spring hole 33 is fixedly connected in the spring hole 33, a return spring 35 is sleeved on the limit ejector rod 34, one end of the return spring 35 is connected with the inner wall of the spring hole 33, and the other end of the return spring is connected with the push plate 56. The return spring 35 can provide a return force for the return of the push plate 56 after pushing, when the push plate 56 is driven by the synchronous belt 53 to move forward (i.e. towards the direction of the discharging end), the return spring 35 is stretched, after the pushing action is completed, the driving force of the synchronous belt 53 to the push plate 56 disappears, and the push plate 56 is pulled by the return spring 35 to return backward.

The position limiting mandril 34 limits the backward movement position of the push plate 56 and prevents the push plate from moving excessively backward. On the other hand, the limiting ejector rod 34 can also be matched with the pushing mechanism 5, so that when the rack surface 60 is inserted downwards, the one-way gear 52 basically cannot rotate, specifically: when the rack face 60 moves downwards and is meshed with the driving gear 51, the driving gear 51 drives the first rotating shaft 50 to rotate anticlockwise, the first rotating shaft 50 can rotate anticlockwise relative to the one-way gear 52, due to inertia, the one-way gear 52 can also have a trend of anticlockwise rotation, so that the push plate 56 has a trend of backwards movement, at the moment, the push plate 56 is blocked by the limiting ejector rod 34 and cannot move backwards, the one-way gear 52 is limited to not rotate anticlockwise basically, at the moment, the first rotating shaft 50 rotates anticlockwise freely, the one-way gear 52 keeps still, and the synchronous belt 53 and the push plate 56 cannot move.

In the preferred embodiment, the driving gear 51, the one-way gear 52, the driven gear 54 and the timing belt 53 are all symmetrically arranged in pairs, and the driving plate 6 and the driving slot 31 corresponding to the driving gear are also in pairs, so as to improve the stability of the mechanism motion.

Furthermore, the discharge end of the pressing table-board 4 is also provided with an inclined discharge sliding plate 40.

In this embodiment, when the driving mechanism 2 drives the pressing head 1 to press the material 8 downwards, the driving plate 6 is inserted into the driving slot 31 from top to bottom, and the pushing plate 56 does not act at this time; when the material pressing operation is finished and the pressing head 1 moves upwards, the driving plate 6 falls off the driving slot 31 from bottom to top, and the pushing plate 56 moves forwards to push the pressed material 8 away from the pressing table top 4. The specific working process is as follows: when the pressure head 1 moves downwards, the driving plate 6 is driven to move downwards and is inserted into the driving slot 31, the rack surface 60 on the driving plate 6 is meshed with the driving gear 51 to drive the driving gear 51 to rotate anticlockwise, the driving gear 51 drives the first rotating shaft 50 to rotate anticlockwise, and because the first rotating shaft 50 can rotate anticlockwise relative to the one-way gear 52 at the moment, the synchronous belt 53 and the limiting ejector rod 34 also form a certain resistance effect on the one-way gear 52, the one-way gear 52 keeps static and cannot rotate along with the first rotating shaft 50, and at the moment, the synchronous belt 53 and the push plate 56 keep static (as shown in fig. 2 and 6); after the pressing head 1 finishes the extrusion operation on the material 8 on the pressing table-board 4, the driving mechanism 2 drives the pressing head 1 to move upwards and reset, the rack face 60 on the driving board 6 moves upwards relative to the driving slot 31, the rack face 60 drives the driving gear 51 to rotate clockwise, the driving gear 51 drives the first rotating shaft 50 to rotate clockwise, at the moment, the one-way gear 52 cannot rotate relative to the first rotating shaft 50, so that the one-way gear 52 also rotates clockwise along with the first rotating shaft 50, the synchronous belt 53 drives the push plate 56 to move forwards (as shown in the states of fig. 5 and 7) under the cooperation of the driven gear 54, the material 8 pressed on the pressing table-board 4 is pushed to the discharging end, and is discharged through the inclined discharging sliding plate 40 to enter the next operation position. Therefore, only one driving motor 20 is needed, and the return power of the upward reset of the pressure head 1 is used as the driving force of the pushing mechanism 5, so that the compressed material 8 is automatically pushed away from the compression table top 4.

The one-way gear 52 may be selected from conventional products to perform the functions in the mechanism described above. In this embodiment, the one-way gear 52 includes a one-way bearing disposed on the first rotating shaft 50 and a gear body disposed on an outer ring of the one-way bearing (in this embodiment, a CSK15PP one-way bearing may be used), and the one-way bearing is capable of freely rotating in one direction and is locked in the opposite direction. That is, the one-way bearing is rotatable on the first rotating shaft 50 in one direction, and is not rotatable with respect to the first rotating shaft 50 in the opposite direction.

It should be understood that, the pressing table 4 is provided with a pressing working area 41, the pressing head 1 moves up and down right above the pressing working area 41, and the pushing plate 56 is located outside the pressing working area 41 after being reset backwards, so that the pressing head 1 cannot contact with the pushing plate 56 when being pressed downwards.

The driving mechanism 2 is used for providing power for the up-and-down movement of the pressure head 1, in a preferred embodiment, the material 8 pressing device further comprises a supporting frame 7, the driving mechanism 2 comprises a motor 20 arranged on the supporting frame 7, a screw rod 21 in driving connection with an output shaft of the motor 20, a nut seat 22 in threaded connection with the screw rod 21, a driving connecting rod 23 connected to the bottom end of the nut seat 22, and a guide sleeve 24 connected to the supporting frame 7 and used for limiting the rotation of the nut seat 22, and the lower end of the driving connecting rod 23 is connected with the upper end of the pressure head 1.

A slide hole 240 is formed in the guide sleeve 24, and the nut seat 22 can be arranged in the slide hole 240 in a vertical sliding manner; the upper end of the guide sleeve 24 is provided with a screw hole 241 which is inserted by the screw 21 and penetrates to the slide hole 240, and the lower end of the guide sleeve 24 is provided with a link hole 242 which is extended by the driving link 23 and is communicated with the slide hole 240.

The middle part of the nut seat 22 is provided with a threaded hole 220 for inserting the screw rod 21, the nut seat 22 is also provided with at least two guide holes 221 which are penetrated up and down, and the inner wall of the guide sleeve 24 is connected with a guide rod 25 which is matched with and penetrates through the guide holes 221. In the preferred embodiment, the guide holes 221 include four guide rods 25 uniformly spaced around the circumference of the threaded hole 220. The nut holder 22 cannot rotate due to the restriction of the guide rod 25, and the nut holder 22 can only linearly move up and down on the lead screw 21 due to the rotation of the lead screw 21. Further, a linear bearing 26 is arranged between the nut seat 22 and the inner wall of the guide sleeve 24, and the nut seat 22 can slide up and down relative to the linear bearing 26.

The operating principle of the driving mechanism 2 in this embodiment is: when the material 8 is compacted, the motor 20 works to drive the screw rod 21 to rotate, the nut seat 22 in threaded fit with the screw rod moves downwards, and the driving connecting rod 23 at the bottom drives the pressure head 1 to move downwards to extrude the material 8; after the compaction is finished, the motor 20 rotates reversely, and the nut seat 22 moves upwards under the driving of the screw rod 21 to drive the pressure head 1 to move upwards for resetting.

While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
