Description

Technical Field

[0001] This utility model relates to the technical field of EPE foam stamping equipment, specifically to a stamping waste removal device for EPE foam production. Background Technology

[0002] EPE foam is a new type of environmentally friendly packaging material. When EPE foam leaves the factory, it is in the form of a complete sheet. In order to meet the packaging needs of different products, the sheet EPE foam needs to be stamped into different shapes and specifications, so EPE foam stamping equipment is used.

[0003] A search revealed a patent, CN221872219U, which discloses a stamping waste removal device for EPE foam production. The device includes a gantry frame with bases on both its front and rear sides. A hydraulic cylinder is fixedly connected to the top of the gantry frame, with its output end penetrating and slidably connected to the top of the gantry frame. A connecting plate is fixedly connected to the output end of the hydraulic cylinder. A stamping plate is located at the bottom of the connecting plate, and evenly distributed mounting holes are formed in the middle of the connecting plate. A mounting seat is fixedly connected to the top of the stamping plate, and a mounting rod is slidably connected through the top of the mounting seat. In this invention, the mounting rod can be disassembled by pressing the disassembly rod to push it into the mounting seat. Installation is completed by inserting the mounting seat into the connecting plate, where a spring pushes the mounting rod out and inserts it into the mounting hole for positioning. This method is efficient and avoids damage to screws caused by stamping.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a method where the pearl cotton to be stamped is fed between a transmission wheel and a pressing plate, and the pressing plate is lowered to fix the pearl cotton. A hydraulic cylinder then drives the stamping plate to move downwards, stamping the pearl cotton. However, in reality, due to the elasticity of pearl cotton, and the fact that the aforementioned comparative document only presses the edges of the pearl cotton without supporting the middle, the middle of the pearl cotton may collapse during stamping, potentially resulting in incomplete stamping. Furthermore, a ring cutter may be used during the stamping process. The ring cutter has an internal cavity, and the pearl cotton cut off after stamping may become stuck inside the ring cutter, affecting subsequent stamping. In this case, manual removal of the pearl cotton stuck inside the ring cutter is required, reducing the efficiency of the pearl cotton stamping process. Therefore, there is an urgent need in the art to improve the stamping waste removal device for pearl cotton production to overcome the shortcomings of the prior art. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] Example 1

[0029] Please see Figures 1-6 A stamping waste removal device for EPE foam production includes a support base 1. A rotary table 2, capable of intermittently rotating along the axis of the support base 1, is rotatably connected to the upper part of the support base 1. Several stamping positioning dies 4, equidistantly arranged along the axis of the support base 1 and adapted to the EPE foam 11 to be stamped, are provided on the upper part of the support base 1. A fixed frame 5 is provided on one side of the rotary table 2. A first telescopic device 6 with a telescopic effect is provided on the upper part of the fixed frame 5. A connecting frame 7 is provided at the lower end of the telescopic device 6. A ring-shaped punching cutter 8 for punching the EPE foam 11 is provided at the lower part of the connecting frame 7. The ring-shaped punching cutter 8 has an upper part... A second telescopic device 9 with a telescopic effect is provided. The telescopic end of the second telescopic device 9 extends into the annular punching cutter 8 and its end is provided with a waste discharge plate 10 adapted to the cavity inside the annular punching cutter 8. The bottom of the stamping positioning mold 4 is provided with a first waste discharge port 12 adapted to the waste discharge plate 10. A second waste discharge port 13 larger than the first waste discharge port 12 is opened through the rotary table 2. A third waste discharge port 15 larger than the annular punching cutter 8 is provided on the side of the rotary table 2. A main controller 14 is provided on the side of the rotary table 2. A rotary motor 3 is fixedly installed inside the bearing seat 1. The rotary motor 3 is used to rotate the rotary table 2 intermittently.

[0030] In this specific embodiment, when it is necessary to perform through-cutting of the pearl cotton 11, several stamping positioning molds 4 of suitable size are installed on the upper part of the rotary table 2. The pearl cotton 11 to be punched is clamped in the stamping positioning mold 4. The rotary motor 3 is turned on by the main controller 14. The rotary motor 3 drives the rotary table 2 to rotate intermittently. When the stamping positioning mold 4 with the pearl cotton 11 to be punched rotates to the position directly below the annular punching cutter 8, the first telescopic device 6 is activated. The telescopic end of the first telescopic device 6 drives the connecting frame 7 and the annular punching cutter 8 to move down, punching the pearl cotton 11. The punched pearl cotton may be clamped inside the annular punching cutter 8. At this time, the rotary table 2 rotates a distance again, and the annular punching cutter 8 is located at the position of the third row of waste outlets 15. The second telescopic device 6 is activated. The telescopic end of the second telescopic device 9 drives the waste discharge plate 10 to move downward. The waste discharge plate 10 pushes out the pearl cotton stuck in the annular punching cutter 8 and discharges waste through the third waste discharge port 15. If the pearl cotton punched by the annular punching cutter 8 is not stuck in the annular punching cutter 8, the punched pearl cotton falls through the first waste discharge port 12 and the second waste discharge port 13 for waste discharge. This not only provides support for the pearl cotton 11 to be punched, but also prevents the punched pearl cotton from getting stuck in the annular punching cutter 8 through two waste discharge methods, thereby improving the efficiency of punching and cutting the pearl cotton 11. It is worth noting that the depth of the cavity inside the annular punching cutter 8 is greater than the thickness of the pearl cotton 11 to be punched. The movement stroke of the waste discharge plate 10 driven by the second telescopic device 9 is adapted to the depth of the cavity inside the annular punching cutter 8.

[0033] In this embodiment, the stamping positioning die 4 is placed between two first positioning plates 16. The first adjusting threaded rod 18 is rotated, causing the first positioning plates 16 to move on the rotary table 2. The first positioning plates 16 are attached to opposite sides of the stamping positioning die 4. The second adjusting threaded rod 23 is rotated, and the threads of the second adjusting threaded rod 23 located on the inner side of the sliding groove 22 are symmetrical and opposite in direction. When the second adjusting threaded rod 23 rotates, it causes the two sliding plates 21 to move towards each other within the sliding groove 22. The sliding plates 21 then move the two second positioning plates 21 towards each other. The positioning plate 20 moves, and the second positioning plate 20 is tightly attached to the other two sides of the stamping positioning die 4. Then, the first adjusting threaded rod 18, the second adjusting threaded rod 23, the first limiting nut 19 and the second limiting nut 24 are locked. The stamping positioning die 4 is clamped and fixed by the two first positioning plates 16 and the four second positioning plates 20, which facilitates the installation or replacement of the stamping positioning die 4. It can also install stamping positioning dies 4 of different sizes, and the position of the stamping positioning die 4 can be finely adjusted, thereby improving the applicability of the overall stamping device.
