A No. 1 electric telescopic rod 3 is fixed to the front and rear ends of the lower surface of the left end U-shaped frame 2. The lower surfaces of the two No. 1 electric telescopic rods 3 are fixed with the same cutting knife 4. A positioning mechanism 5 for positioning the aluminum veneer is provided on the left side of the workbench 1, a surface flaw detector 6 is fixed on the lower surface of the right end U-shaped frame 2, and a dust extraction mechanism 7 for dust extraction is provided at the bottom of the inner wall of the U-shaped frame 2.

[0023] Among them, a No. 2 electric telescopic rod is fixed to the left end of the upper surface of the workbench 1 and on the left side of the cutter 4, a push plate is fixed to the right side of the No. 2 electric telescopic rod, and a No. 3 electric telescopic rod is fixed to the left side of the bottom of the right end of the workbench 1. A baffle is fixed on the upper surface of the No. 3 electric telescopic rod, and the upper surface of the baffle passes through the workbench 1 and extends to the upper side of the workbench 1. The controller controls to start the No. 1 electric telescopic rod 3. The extension of the No. 1 electric telescopic rod 3 can push the cutter 4 to move downward, and then the aluminum veneer can be sheared. After shearing, the controller controls to start the No. 2 electric telescopic rod. The extension of the No. 2 electric telescopic rod causes the push plate to push the aluminum veneer to move.

[0026] See also Figure 2In order to improve the shearing quality of the aluminum veneer, the positioning mechanism 5 in this embodiment includes a driving motor fixed to the left side of the workbench 1. The output shaft of the driving motor passes through the workbench 1 and extends to the inner cavity of the workbench 1 and is fixed with a rotating rod 501. A cam 502 is fixed on the back of the rotating rod 501. A movable rod 503 is fixed to the bottom of the back of the cam 502. When the driving motor is started, the output shaft of the driving motor rotates to drive the rotating rod 501 to rotate. The rotation of the rotating rod 501 drives the cam 502 to rotate counterclockwise. The rotation of the cam 502 can drive the movable rod 503 to rotate. A linkage ring 504 is provided on the outside of the movable rod 503. A rotating gear 505 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the workbench 1 through a bearing. The movement of the movable rod 503 can drive the linkage The ring 504 moves forward, and the forward movement of the linkage ring 504 drives the upper tooth plate 506 to move forward, which in turn drives the rotating gear 505 to rotate. The upper and lower sides of the rotating gear 505 are meshed with tooth plates 506, and the linkage ring 504 is fixed to the right end of the upper tooth plate 506. One side of the two tooth plates 506 is fixed with a linkage plate 507, and the opposite side of the two linkage plates 507 is fixed with a clamping plate 508. The rotation of the rotating gear 505 can drive the lower tooth plate 506 to move backward. At this time, the two tooth plates 506 make relative motion, and the movement of the two tooth plates 506 can drive the two linkage plates 507 to make relative motion. The movement of the linkage plate 507 can drive the clamping plate 508 to move, so that the two clamping plates 508 make relative motion, thereby clamping the two sides of the aluminum veneer.

[0027] Among them, a sliding groove is opened in the middle of the opposite side of the inner top wall and the inner bottom wall of the workbench 1, and a slider is fixed on the opposite side of the two tooth plates 506. The slider moves back and forth in a straight line in the inner cavity of the sliding groove.

[0028] In this embodiment, the upper surface of the splint 508 passes through the workbench 1 and extends to the upper side of the workbench 1.

When cleaning, the staff can centrally process the debris by opening the box door, and pull out the dust cover 706 from the two sliding seats 705. The dust cover 706 can be replaced regularly. The inner cavities of the two sliding seats 705 are slidably connected with the same dust cover 706. The set dust cover 706 can prevent dust from entering the inner cavity of the fan 704 and causing the fan 704 to malfunction.

[0031] Among them, the other end of the material guide tube 702 is fixed to the upper surface of the aggregate box 703 and is connected to the inner cavity of the aggregate box 703.

[0033] The electrical components appearing in the text are all electrically connected to the main controller and the power supply, and the electrical components appearing in the text are all conventionally known devices. This application will not go into too much detail. The main controller can be a conventionally known device that controls a computer, etc. The control circuit of the main controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0034] The working principle of the above embodiment is:

[0035] (1) Place the aluminum veneer on the lower side of the cutter 4, and then start the driving motor. The output shaft of the driving motor rotates to drive the rotating rod 501 to rotate. The rotation of the rotating rod 501 drives the cam 502 to rotate counterclockwise. The rotation of the cam 502 can drive the movable rod 503 to rotate, and then the movement of the movable rod 503 can push the linkage ring 504 to move forward. The forward movement of the linkage ring 504 drives the upper side gear plate 506 to move forward, and then drives the rotating gear 505 to rotate. The rotation of the rotating gear 505 can drive the lower side gear plate 506 to move backward. At this time, the two gear plates 506 make relative motion. The movement of the two gear plates 506 can drive the two linkage plates 507 to make relative motion. The movement of the linkage plate 507 can drive the clamping plate 508 to move, so that the two clamping plates 508 make relative motion, and then the two sides of the aluminum veneer can be clamped. Then the control The controller controls to start the No. 1 electric telescopic rod 3. The extension of the No. 1 electric telescopic rod 3 can push the cutter 4 to move downward, thereby shearing the aluminum veneer. After shearing, the controller controls to start the No. 2 electric telescopic rod. The extension of the No. 2 electric telescopic rod causes the push plate to push the aluminum veneer to move. When the aluminum veneer moves to the lower side of the surface flaw detector 6, it can be blocked by the baffle, and the surface flaw detector 6 can perform flaw detection on the aluminum veneer. If the test result is qualified, the controller controls the No. 3 electric telescopic rod to shorten, thereby driving the baffle to move downward until the upper surface of the baffle is parallel to the workbench 1, so that the aluminum veneer can fall from the upper surface of the workbench 1 into the collection basket; if the test result is unqualified, the controller can control the start of the rotating motor, the output shaft of the rotating motor rotates, thereby driving the carrying plate 8 to rotate, so that the carrying plate 8 can be separated from the workbench 1, and then the aluminum veneer can fall into the collection basket under its own gravity.

[0036] (2) During the shearing process, debris will be generated. By starting the fan 704, the fan 704 will generate negative pressure in the inner cavity of the collection box 703, and then the debris falling on the upper surface of the workbench 1 can be sucked into the inner cavity of the guide tube 702 through the guide tube 702 and the guide cylinder 701. Then, the debris will enter the inner cavity of the collection box 703 as guided by the guide tube 702, and the generated debris can be collected. The dust cover 706 can be set to prevent dust from entering the inner cavity of the fan 704 and causing the fan 704 to malfunction. When cleaning, the staff can centrally handle the debris by opening the box door and pull out the dust cover 706 from the two sliding seats 705. The dust cover 706 can be replaced regularly.
