[0022] like Figure 1 , Figure 2 and Figure 4 As shown, two support rods 16 are fixedly connected between the supporting feet of the workbench 1, and an adjusting seat 17 is fixedly connected to the top of the two support rods 16. A square groove 18 is opened on the top of the adjusting seat 17, and a screw rod 19 is rotatably connected inside the square groove 18. A movable plate 20 is meshed on the outer surface of the screw rod 19. The bottom end of the movable plate 20 is slidably connected to the top of the adjusting seat 17, and two collecting boxes 22 are arranged on the top of the movable plate 20. By setting the screw rod 19, the movable plate 20 can be driven to move, so as to facilitate the adjustment of the position of the collecting box 22.
[0023] like Figure 4As shown, a positioning frame 21 is fixedly connected to the top of the movable plate 20, and the bottom ends of two collecting boxes 22 are plugged into the interior of the positioning frame 21, so as to facilitate the positioning of the collecting boxes 22.
[0024] like Figure 1 and Figure 2 As shown, four positioning plates 14 are fixedly connected to the top of the workbench 1, and two clamping rollers 15 are rotatably connected to the top of the four positioning plates 14. By setting the positioning plates 14, the adhesive film can be positioned to prevent the waste position from being different from the position of the through hole of the blanking plate 12. By setting the clamping rollers 15, the adhesive film can be tightly fitted to the workbench 1.
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a guide frame 13 is fixedly connected to the bottom of the workbench 1 and located at the position of the fixed through hole 11. Exhaust holes 23 are opened on both sides of the two collecting boxes 22. By setting the guide frame 13, waste can be prevented from flying out of the collecting box 22.

[0028] The utility model provides a waste discharge device for die-cutting adhesive films, and the specific working principle is as follows:
[0029] When the die-cut product is discharged, the cylinder 3 pushes the air intake hood 4 to move, so that the sealing frame 6 contacts the top surface of the workbench 1 and shrinks into the adjusting frame 5 under the thrust of the cylinder 3. The return spring 7 is subjected to pressure and elastically deforms to exert a reaction force on the sealing frame 6 to make the sealing frame 6 in close contact with the workbench 1. The hollow sealing gasket 8 is subjected to pressure and deforms to fit closely with the workbench 1, so that the air intake hood 4 is completely sealed. Then the air pump 9 pumps gas into the air intake hood 4 through the hose 10. The air pressure in the air intake hood 4 increases to blow the waste in the product out of the gap in the blanking plate 12. When the collection box 22 located directly below the guide frame 13 is full of waste, the staff rotates the screw rod 19, and the screw rod 19 drives the movable plate 20 to move in the adjusting seat 17 and drives the collection box 22 to move, so that the new collection box 22 enters under the guide frame 13, and the collection box 22 filled with waste is put back in place again after the waste is poured out.
