Figure 1 A waste discharge device for a die-cutting machine comprises a frame 1, a support plate 2 is fixed on the left side of the upper surface of the frame 1, a top cylinder 3 is fixed through the inside of the support plate 2, a feed hopper 4 is connected to the left side of the outer surface of the top cylinder 3, a hydraulic rod 5 is fixed on the upper surface of the inside of the top cylinder 3, the bottom end of the output shaft of the hydraulic rod 5 passes through the inside of the top cylinder 3, and a pressing plate 6 is fixed, a bottom plate 7 is fixed inside the frame 1, a forming barrel 8 is provided on the left side of the upper surface of the bottom plate 7 below the feed hopper 4, a hydraulic rod 22 is fixed on the left side of the lower surface of the bottom plate 7, a pressing plate 2 9 is slidably connected to the inside of the forming barrel 8, and the top end of the output rod of the hydraulic rod 22 passes through the inside of the forming barrel 8.

[0022] Reference Figure 2-4 A motor 10 is fixed at the center of the lower surface of the bottom plate 7, a rotating shaft 11 is fixed at the top of the output shaft of the motor 10, the top of the rotating shaft 11 passes through the inside of the middle frame 1, two cross frames 12 are fixed on the outer surface of the rotating shaft 11, the left ends of the two cross frames 12 are respectively located at the front and rear of the forming barrel 8, and the two cross frames 12 are rotatably connected to the forming barrel 8. A through groove 14 is opened on the left and right sides of the lower surface of the forming barrel 8, and a slide 15 is stuck on the left and right sides of the outer surface of the forming barrel 8. The slide 15 is connected to the inside of the through groove 14, and the front and rear surfaces of the slide 15 are opened. The slide 16 is opened inside the slide 15. The part is slidably connected with a slider 17 inside the two slide grooves 16, a vertical rod 18 is fixed to the lower surface of the slider 17, a cross rod 19 is fixed to the bottom end of the vertical rod 18, the right end of the cross rod 19 is located at the bottom of the inside of the forming barrel 8 and a connecting rod 20 is fixed, the outer surface of the connecting rod 20 is slidably connected with a connecting tube 21, and the tops of the two connecting tubes 21 are fixedly connected to the lower surface of the pressing plate 29; when the hydraulic rod 22 pushes the pressing plate 29 to rise, the connecting tube 21 will rise with the pressing plate 29, and when the forming barrel 8 is turned over to discharge the waste blocks, the waste blocks do not slide down directly, and the staff can press down the pressing plate 29 to make the waste blocks slide out.

[0023] Reference Figure 2 The outer surface of the pressing plate 6 fits with the inner surface of the top cylinder 3, the outer surface of the pressing plate 2 9 fits with the inner surface of the forming barrel 8, and the output end of the hydraulic rod 22 fits with the lower surface of the pressing plate 2 9, so that waste cannot pass between the pressing plate 6 and the top cylinder 3, waste cannot pass through the gap between the pressing plate 2 9 and the forming barrel 8, and the pressing plate is more stable when moving up and down.

[0024] Reference Figure 2-4 The slider 17 is a cross-shaped structure. The slider 17 cannot be separated from the forming barrel 8 when the slide groove 16 is limited. The left side of the outer surface of the forming barrel 8 is an arc-shaped structure and fits with the inner surface of the frame 1. When the forming barrel 8 is limited by the frame 1, it cannot shake when it rotates and moves, thereby improving safety.

[0025] Reference Figure 1 The frame 1 and the right side of the bottom plate 7 are jointly provided with an outlet 13, and the molding barrel 8 is adapted to the outlet 13.

[0026] The implementation principle of the waste discharge device of a die-cutting machine in the embodiment of the present application is as follows: when in use, the waste discharged by the die-cutting machine enters the interior of the top cylinder 3 through the feed hopper 4, and falls into the interior of the forming barrel 8, and is supported by the second pressing plate 9. When the waste is accumulated to a certain extent, the two hydraulic rods are controlled to operate, and the two pressing plates move relatively, thereby compressing the waste between the two pressing plates, and squeezing the upper and lower parts at the same time, so that the compression efficiency is accelerated and the compressed volume is smaller;

[0027] After compression, the hydraulic rod contracts and moves away from the inside of the forming barrel 8. The motor 10 operates to rotate the rotating shaft 11 to drive the two horizontal frames 12 and the forming barrels 8 to rotate. When rotating, the forming barrel 8 is limited by the frame 1 and cannot shake, so the safety is relatively high. When it moves to the exit 13, the personnel can rotate the forming barrel 8 to turn it over with the top opening facing downward. At this time, the forming waste block will fall from the exit 13, which is convenient and quick to take.
