[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 A punching device for producing pearl cotton includes a support frame 1, a placement plate 2 located at the lower part of the support frame 1, a plurality of punch holes 3 passing through the placement plate 2, a punching plate 4 located above the placement plate 2 located inside the support frame 1, a plurality of circular cutters 5 adapted to the punch holes 3 located at the lower part of the punching plate 4, a lower moving plate 6 located above the punching plate 4 located inside the support frame 1, a telescopic device 7 with telescopic effect fixedly installed on the lower moving plate 6, a displacement plate 8 fixedly installed at the lower telescopic end of the telescopic device 7, a plurality of connecting posts 9 passing through the punching plate 4 fixedly installed at the lower part of the displacement plate 8, one end of the connecting post 9 extending into the circular cutter 5 and the end fixedly installed with a push-out plate 10 adapted to the circular cutter 5, and a first drive motor 11 located on the upper part of the support frame 1 for driving the punching plate 4 and the lower moving plate 6 to move up and down.

[0028] Specifically, when punching holes in the EPE foam board, the EPE foam board is placed on the upper part of the placement plate 2 and aligned. The first drive motor 11 is started by the external main controller. The first drive motor 11 drives the punching plate 4 and the lowering plate 6 to move down simultaneously. The downward movement of the punching plate 4 drives the circular cutter 5 to move down, punching holes in the EPE foam board. When the circular cutter 5 has completely punched the EPE foam board, the first drive motor 11 stops driving. At this time, the telescopic device 7 is started. The telescopic end of the telescopic device 7 drives the displacement plate 8 to move down. The displacement plate 8 drives several connecting posts 9 to move down. The connecting posts 9 drive the positions located on the lower plate to move down. The ejector plate 10 inside the circular cutter 5 moves downward, pushing the waste material inside the circular cutter 5 after punching the pearl cotton board downward until the waste material inside the circular cutter 5 is completely pushed out. Then, the first drive motor 11 is started again to drive the punching plate 4 and the lowering plate 6 to move upward, removing the pearl cotton board after punching. The displacement plate 8 is driven downward by the telescopic device 7. The displacement plate 8 drives the ejector plate 10 through the connecting column 9 to push out the pearl cotton waste material stuck in the circular cutter 5. There is no need to manually remove the pearl cotton waste material inside the circular cutter 5, which improves the efficiency of punching the pearl cotton board.

[0029] As a technical optimization of this utility model, the placement plate 2, the perforated plate 4 and the lowering plate 6 are all fixedly installed with plug strips 13 on opposite sides. The inner sidewalls of the support frame 1 are provided with several connecting seats 12 that are adapted to the plug strips 13. The side of the connecting seat 12 is provided with a plug groove 14 that is adapted to the plug strips 13. Several limiting rods 15 with T-shaped cross sections are passed through one side of each connecting seat 12. The side of the connecting seat 12 is provided with a groove 16 that is adapted to the limiting rods 15. The side of the plug strip 13 is provided with a limiting hole 17 that is adapted to the end of the limiting rod 15. A spring 18 is fixedly installed between the side of the limiting rod 15 and the inner sidewall of the groove 16. The plug strip 13 has a T-shaped cross section and is adapted to the plug groove 14.

[0030] Specifically, when it is necessary to punch holes of different shapes or sizes in the pearl cotton board, the placement plate 2, the punching plate 4, or the lowering plate 6 are replaced and installed. The limiting rod 15 is pulled away from the connecting seat 12. At this time, the spring 18 is stretched, and the insertion strip 13 on the side of the placement plate 2, the punching plate 4, or the lowering plate 6 is inserted into the insertion groove 14 on the connecting seat 12. The limiting hole 17 on the side of the insertion strip 13 is aligned with the end position of the limiting rod 15. The limiting rod 15 is released, and the tension of the spring 18 drives the limiting rod 15 to move. One end of the limiting rod 15 is inserted into the limiting hole 17, which completes the replacement of the placement plate 2, the punching plate 4, and the lowering plate 6, thus improving the applicability of the punching device. The connecting seat 12 that is compatible with the placement plate 2 is fixedly installed on the inner wall of the support frame 1, and the connecting seat 12 that is connected to the punching plate 4 and the lowering plate 6 is slidably connected to the inner wall of the support frame 1.

[0031] As a technical optimization of this utility model, a first sliding block 19 is fixedly installed on the side of the connecting seat 12 located on the side of the perforated plate 4, and a second sliding block 20 is fixedly installed on the side of the connecting seat 12 located on the side of the lower moving plate 6. The inner side walls of the support frame 1 are provided with a first sliding groove 21 that is adapted to the second sliding block 20. A first driving screw 22 is rotatably connected in the first sliding groove 21, one end of which is fixedly installed to the output end of the first drive motor 11. The first driving screw 22 passes through the first sliding block 19 and the second sliding block 20 and is threadedly connected to them.

[0032] Specifically, when punching, the first drive motor 11 is started. The output end of the first drive motor 11 drives the first drive screw 22 to rotate. When the first drive screw 22 rotates, it drives the first sliding block 19 and the second sliding block 20 to move simultaneously in the first sliding groove 21. The first sliding block 19 drives the punching plate 4 to move, and the second sliding block 20 drives the lower moving plate 6 to move, so as to achieve the effect of moving the punching plate 4 and the lower moving plate 6 simultaneously.

[0033] As a technical optimization of this utility model, a number of second drive motors 23 are fixedly installed on the upper part of the support frame 1.

The second drive screw 26 passes through the third sliding block 24 and is threadedly connected to it. A pressure plate 27 is fixedly installed on one side of the third sliding block 24.

[0034] Specifically, the pearl cotton sheet to be punched is placed on the upper part of the placement plate 2, and the position of the pearl cotton sheet is aligned with the punching opening 3. Then, several synchronous second drive motors 23 are started. The output end of the second drive motor 23 drives the second drive screw 26 to rotate. When the second drive screw 26 rotates, it drives the third sliding block 24 to move in the second sliding groove 25. The third sliding block 24 drives the pressing plate 27 to move, pressing the pearl cotton sheet located on the upper part of the placement plate 2, improving the stability when punching the pearl cotton sheet. Moreover, each pressing plate 27 is driven independently, which can press the pearl cotton sheet with concave and convex shape in the upper part, thus improving the applicability of the device.

[0035] As a technical optimization of this utility model, an inclined plate 28 is fixedly installed between the opposite side walls of the lower part of the support frame 1. The inclined plate 28 is inclined and adapted to the placement plate 2. The pushed-out pearl cotton waste slides out through the inclined plate 28 and is collected in a concentrated manner.
