Preferably, in order to facilitate the engagement between the second slider 28 and the guide rod 27, both ends of the guide rod 27 are provided with chamfers.

The chamfer serves to reduce the diameter of the guide rod 27 as it passes through the second slider 28, which has the effect of facilitating installation.

Preferably, in order to improve the stability of the installation of the collection tube 18, the material of the transmission rod 22 is a magnet, and the material of the collection tube 18 is iron.

The reliability of the connection of the transmission rod 22 to the collector tube 18 is increased by the attraction between the iron and the magnet.

Preferably, the number of teeth of the driving bevel gear 6 is greater than that of the driven bevel gear 13 in order to enhance the heat dissipation effect.

In the gear transmission, the number of teeth is inversely proportional to the rotating speed, that is, the rotation of the fan blades 17 can be improved, so that the air flow rate is improved, the heat dissipation effect can be improved, and meanwhile, the reliability of collecting scraps can be improved.

During the use of the device, the lifting rod 2 drives the cutting line 3 to reciprocate through the power device, when gold is abutted against the cutting line 3, the cutting line 3 can cut gold, the reciprocating lifting of the lifting rod 2 can drive the rotating gear 9 to reciprocate on the rack 8, namely, the rotating gear 9 can drive the rotating shaft 7 to reciprocate under the supporting action of the first bearing 10, the reciprocating lifting of the rotating shaft 7 drives the driven bevel gear 13 to reciprocate through driving the bevel gear 6, namely, the connecting shaft 14 can reciprocate under the supporting action of the second bearing 15, the reciprocating rotation of the connecting shaft 14 drives the inner ring of the one-way bearing 16 to reciprocate, as the one-way bearing 16 can freely rotate in one direction and is a bearing locked in the other direction, the outer ring of the one-way bearing 16 can intermittently and unidirectionally rotate, and in the outer rings of the two one-way bearings 16, at most, only one of the blades is in a rotating state, the blades 17 are driven to rotate by the rotation of the outer ring of the one-way bearing 16, the sealing disc 12 moves towards the direction far away from the fixed tube 4 and is separated from the air tube 11 by the rotation of the outer ring of the one-way bearing 16 through the moving unit, so that air in the fixed tube 4 can be discharged from only one air tube 11 all the time, air outside the fixed tube 4 is conveyed into the fixed tube 4 from one end of the fixed tube 4 close to the cutting line 3, namely, the air flow rate around the cutting line 3 and gold can be accelerated, the heat dissipation of the cutting line 3 and the gold can be realized, the cutting accuracy is prevented from being influenced by the thermal expansion of the cutting line 3 and the gold, the collecting tube 18 is driven to rotate by the driving rod 22 by the rotation of the rotating shaft 7, and the moving disc 21 can move towards the direction far away from the cutting line 3 and is separated from the fixed ring 20 by the rotation of the collecting tube 18 through the connecting assembly, thereby can make the air carry go into fixed pipe 4 in to the collecting pipe 18 back, and realize gold clastic the holding back through filter screen 19, after lifter 2 stops going up and down, then can make removal dish 21 antiport and laminate with solid fixed ring 20 through coupling assembling, thereby can prevent that the piece that holds back from taking place to leak on the filter screen 19, when the piece on filter screen 19 is clear away to needs, take out collecting pipe 18, and discharge the piece in the collecting pipe 18 from the relief hole, filter screen 19 is clean after finishing, install collecting pipe 18 again on fixed pipe 4.

Compared with the prior art, this a cutting equipment for gold processing has realized radiating function through heat dissipation mechanism, prevent that line of cut 3 and gold from being heated the thermal expansion and influence cutting accuracy, compare with current heat dissipation mechanism, this heat dissipation mechanism passes through the flow of air, can also make in the piece inhales collecting pipe 18, integral type linkage structure has been realized with collection mechanism, the practicality is stronger, moreover, still realized collecting the clastic function of gold through collection mechanism, compare with current collection mechanism, this collection mechanism can also prevent that the piece of holding back from taking place to leak on the filter screen 19, the practicality is stronger.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
