[0045] In the embodiment of the present invention, when the cutting assembly 11 moves upward, the first positioning rod 14 that moves upward is connected to the first transmission gear 31 through the first meshing tooth groove 16 to drive the rack plate 34, the suction valve 43 and the tubular air valve 38 to move toward the cutting chamber 212. The first bent plate 35 that moves with the rack plate 34 drives the top block 221 to move upward by sliding contact with the wedge block 223. When the suction valve 43 is located directly above the top block 221 or the workpiece 8, the first meshing tooth groove 16 disengages from the first transmission gear 31, and the tubular air valve 38 is located on one side of the workbench frame 211. At this time, the second positioning rod 15 that moves upward is connected to the third transmission gear 47 through the second meshing tooth groove 17 to drive the pressure plate 49 to squeeze the bent pipe 42 downward, thereby controlling the contact between the suction valve 43 and the surface of the workpiece 8.

[0046] See also Figure 5 and Fig.11 In one embodiment of the present invention, the workbench 21 also includes a chip removal port 214, a chip collection box 215 and an inclined plate 216. A chip removal port 214 is provided on one side of the workbench frame 211.

[0048] In an embodiment of the present invention, the push plate 36 that moves with the rack plate 34 cleans the waste chips in the workbench frame 211 through the chip discharge port 214 into the chip collection box 215 to prevent the waste chips from being blocked and causing the waste chips to fall poorly, resulting in material jamming or unstable material discharge in the cutting chamber 212.

[0049] Working principle: When the workpiece 8 is cut, the longitudinal cylinder 13 first controls the cutting assembly 11 to move upward, and the first positioning rod 14 that moves upward controls the second transmission gear 32 to rotate through the first meshing tooth groove 16 and the first transmission gear 31. The rotating second transmission gear 32 controls the suction valve 43 and the tubular air valve 38 to move toward the direction close to the cutting cavity 212 through the rack plate 34. On the one hand, the first bent plate 35 that moves with the rack plate 34 achieves the purpose of driving the top block 221 to move upward by sliding contact with the wedge block 223. On the other hand, the push plate that moves with the rack plate 34 36 cleans the waste chips in the workbench frame 211 into the chip collection box 215 through the chip discharge port 214 to prevent the waste chips from being blocked and causing the waste chips to fall poorly, resulting in material jamming or uneven material discharge in the cutting chamber 212. In addition, when the tubular air valve 38 moving with the rack plate 34 passes between the cutting component 11 and the cutting chamber 212, the multi-directional airflow ejected outward by the air pump 51 through the second flexible tube 52 and the tubular air valve 38 can clean up the waste chips adhered to the surface of the cutting component 11 and the cutting chamber 212, thereby preventing the problem of dents, scratches and other defects on the surface of the workpiece 8 during secondary cutting.

[0050] When the suction valve 43 is located directly above the top block 221 or the workpiece 8, the first meshing tooth groove 16 is disengaged from the first transmission gear 31, and the tubular air valve 38 is located on one side of the workbench frame 211. At this time, the second positioning rod 15 moving upward controls the third transmission gear 47 to rotate through the second meshing tooth groove 17. The rotating third transmission gear 47 drives the pressing plate 49 to squeeze the bent pipe 42 downward through the rack rod 48, so that the suction valve 43 contacts the surface of the workpiece 8, which is convenient for the suction valve 43 to adsorb and fix the workpiece 8.

[0051] When the cutting assembly 11 is controlled to move downward for cutting, the second positioning rod 15 moving downward is connected to the third transmission gear 47 through the second meshing tooth groove 17 to drive the pressing plate 49 out of the bent pipe 42. At this time, the upward elastic force of the second return spring 46 drives the workpiece 8 out of the top block 221 or the workbench frame 211. When the second meshing tooth groove 17 is disengaged from the third transmission gear 47, the first positioning rod 14 moving downward is connected to the first transmission gear 31 through the first meshing tooth groove 16 to drive the rack plate 34, the suction valve 43 and the tubular air valve 38 to move away from the cutting chamber 212. When the suction valve 43 is in the When it is above the conveyor belt 6, the tubular air valve 38 is located on the other side of the workbench frame 211, the first bent plate 35 is disengaged from the wedge block 223, and the first meshing tooth groove 16 is disengaged from the first transmission gear 31. At this time, the first meshing tooth groove 16 is disengaged from the first transmission gear 31 until the cutting component 11 and the cutting cavity 212 are squeezed into contact to complete the cutting action, thereby realizing the integrated function of cutting, unloading and cleaning. It can not only prevent the workpiece 8 from being damaged due to the inability to control the force or the residual waste during the unloading process, but also overcome the problem of defects such as dents and scratches on the surface of the workpiece 8 caused by the residual waste or adhesion on the surface of the cutting component 11 and the cutting cavity 212.

[0052] To sum up, the present application utilizes the lifting and lowering movement of the cutting mechanism 1. On the one hand, it can achieve the purpose of automatically unloading the workpiece 8 to the surface of the conveyor belt 6 without damage by accurately controlling the suction valve 43 of the top block 221 and the descending stroke of the suction valve 43. On the other hand, it can automatically clean up the waste chips adhered to the surface of the cutting component 11 and the cutting cavity 212. It can not only solve the problem of damage to the workpiece 8 due to the inability to control the force during the unloading process, but also solve the problem of dents, scratches and other defects on the surface of the workpiece 8 due to residual waste chips. It has the characteristics of clever structural coordination, low cost, high yield rate of workpiece 8 and high work efficiency.
