[0021] The feeding assembly includes a vertically arranged hydraulic cylinder 5, the bottom end of the hydraulic cylinder 5 is fixed at the middle of the top of the arch frame 2, the bottom end of the output shaft of the hydraulic cylinder 5 vertically passes through the top of the arch frame 2, and a connecting plate 6 is fixed to the bottom end of the output shaft of the hydraulic cylinder 5, a connecting block 7 is fixed to the top of the connecting plate 6, and the top end of the cutter 4 is fixed to the bottom of the connecting block 7. Specifically, when the hydraulic cylinder 5 is in operation, the connecting block 7 can be driven to rise and fall through the connecting plate 6, thereby driving the connecting block 7 to rise and fall, and the cutter 4 can be driven to rise and fall, thereby controlling the cutter 4 to make a feeding movement relative to the foam board 3, and the foam board 3 can be cut;

[0022] The waste extrusion and discharge assembly includes an open groove 8, which is vertically opened in the middle of the bottom of the connecting block 7. A cylindrical shell 9 is fixed inside the open groove 8. The bottom of the cylindrical shell 9 is closed, and a limiting hole 10 is opened in the center of the bottom of the cylindrical shell 9. A guide rod 11 is vertically penetrated in the limiting hole 10, and the hole wall of the limiting hole 10 fits with the surface of the guide rod 11, that is, under the action of the limiting hole 10, the guide rod 11 can move vertically stably, an extrusion plate 12 is fixed at the bottom end of the guide rod 11, and a limiting plate 13 is fixed at the top of the guide rod 11. The side surface of the limiting plate 13 slides on the inner surface of the cylindrical shell 9, that is, when the guide rod 11 moves up and down in a straight line, the limiting plate 13 can move up and down synchronously inside the cylindrical shell 9, and a reset spring 1 is fixed on the top of the limiting plate 13 4, the top of the return spring 14 is fixed to the top of the inner wall of the opening groove 8, so when the cutter 4 moves down to cut the foam board 3, the extrusion plate 12 will abut against the foam board waste located on the inner side of the cutter 4, and then as the cutter 4 continues to move down, the extrusion plate 12 is forced to move upward, thereby driving the limit plate 13 to move upward through the guide rod 11 to squeeze the return spring 14, causing the return spring 14 to undergo elastic deformation and generate elastic force, and then when the cutter 4 completely cuts the foam board 3, that is, when the foam board waste located inside the cutter 4 is separated from the foam board 3 as a whole, under the action of the elastic force of the return spring 14, the limit plate 13 can be pushed down to its original position, thereby causing the guide rod 11 to drive the extrusion plate 12 to move downward, and the foam board waste located in the cutter 4 can be automatically squeezed out (such as Figure 4 shown);

[0023] The waste extrusion and discharge assembly also includes a drop hole 15, which is opened in the middle of the top of the die-cutting table 1. The drop hole 15 is located directly below the cutter 4. A collection box 16 is placed at the bottom of the inner wall of the die-cutting table 1. The drop hole 15 is located above the collection box 16. A door panel 17 is hinged at the front end of the die-cutting table 1. Specifically, the foam board waste automatically squeezed out by the extrusion plate 12 can fall into the collection box 16 through the drop hole 15 for centralized collection (such as Figure 4 As shown), the device can effectively squeeze out the waste material cut from the foam board 3 from the inside of the cutter 4 and automatically drop and collect the waste material, thereby greatly improving the die-cutting efficiency;

The two ends of the foam board 3 are respectively abutted against the opposite ends of the two clamps 20. Specifically, when the two electric push rods 19 are in operation, the two clamps 20 can be controlled to move toward or in the opposite direction, so that the foam board 3 can be clamped and fixed to prevent the foam board 3 from deviating during the cutting process.

[0025] It should be noted that the device is electrically connected to an external main controller and 220V AC power, and the main controller can be a prior art device that controls switches and the like.

[0026] The use process of the utility model is as follows: a person skilled in the art places the foam board 3 to be cut on the top of the die-cutting table 1, and then controls the two clamping plates 20 to move toward each other through the two electric push rods 19 to clamp and fix the foam board 3, and then the hydraulic cylinder 5 is operated to drive the cutter 4 to move downward to perform a die-cutting operation on the foam board 3. When the cutter 4 moves downward to cut the foam board 3, the extrusion plate 12 will abut against the waste foam board located on the inner side of the cutter 4, and then as the cutter 4 continues to move downward, the extrusion plate 12 is forced to move upward, thereby driving the limit plate 13 to move upward through the guide rod 11 to squeeze the reset spring 14, causing the reset spring 14 to occur. The elastic deformation generates elastic force, and then when the cutter 4 completely cuts the foam board 3, that is, the foam board waste inside the cutter 4 is separated from the foam board 3 as a whole, under the action of the elastic force of the reset spring 14, the limit plate 13 can be pushed down to its original position, so that the guide rod 11 drives the extrusion plate 12 to move down, and the foam board waste inside the cutter 4 can be automatically squeezed out, and the foam board waste automatically squeezed out by the extrusion plate 12 can fall into the collecting box 16 through the blanking hole 15 for centralized collection, that is, the device can effectively automatically extrude the waste cut off from the foam board 3 from the inside of the cutter 4, automatically drop the material and collect it in a centralized manner, thereby greatly improving the die-cutting efficiency.

[0027] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
