Technical Field

[0001] This utility model relates to the field of EPE pearl cotton production technology, and in particular to a punching device for EPE pearl cotton production. Background Technology

[0002] EPE (Expanded Polyethylene) foam is a non-crosslinked closed-cell material formed by physical foaming of low-density polyethylene resin. It is lightweight, highly cushioning, waterproof, moisture-proof, and resistant to chemical corrosion. Its internal independent bubble structure overcomes the problems of fragility and deformation of traditional foams, while also possessing excellent shock absorption, sound insulation, and thermal insulation properties.

[0003] During the production and processing of EPE pearl cotton, a punching device is required to punch holes in the surface of the pearl cotton according to production needs. However, the existing punching devices are difficult to automatically collect the pearl cotton waste left after punching. At the same time, the pearl cotton is prone to displacement due to excessive punching force during punching, resulting in low punching stability. Utility Model Content

The hollow punch 8 is fixed to the inner wall of the collection box 7. The connection is as follows: a punching slot 9 is opened on the top surface of the fixed frame 1, and the top block 10 is fixedly connected to the inner wall of the punching slot 9. It is used to punch the pearl cotton and facilitate the conveying of waste into the collection box 7 for automatic collection. The surface of the collection box 7 is provided with an elastic pressing component, which consists of a fixed plate 11, a limiting shaft 12, a pressure plate 13 and a spring 14. The fixed plate 11 is fixedly connected to the surface of the collection box 7, the limiting shaft 12 is slidably connected to the inner wall of the fixed plate 11, the pressure plate 13 is fixedly connected to the bottom end of the limiting shaft 12, and the spring 14 is fixedly connected to the top surface of the pressure plate 13 and the bottom surface of the fixed plate 11. It is used to press down and fix the pearl cotton to prevent displacement and to buffer the punching force. A sealing cover mechanism is provided on the left side of the collection box 7, and a conveying component is provided inside the fixed frame 1.

[0023] Specifically, the sealing cover mechanism consists of a hinge 15, a sealing cover plate 16, and a cover lock 17. The hinge 15 is fixedly connected to the left side of the collection box 7. The sealing cover plate 16 is hinged to the collection box 7 via the hinge 15. The cover lock 17 is fixedly connected to the inner wall of the sealing cover plate 16 and is used to open and close the collection box 7 to prevent waste from scattering.

[0024] Specifically, the conveying assembly consists of a drive roller 18, a conveyor belt 19, a servo motor 20, a drive wheel 21, a transmission belt 22, and a driven wheel 23. Multiple conveyor belts 19 are symmetrically arranged around the vertical center line of the front of the fixed frame 1, for continuous conveying, thus improving conveying stability. The drive roller 18 is rotatably connected to the inner wall of the fixed frame 1, and the inner wall of the conveyor belt 19 meshes with the surface of the drive roller 18. The servo motor 20 is fixedly connected to the bottom surface of the fixed frame 1, the inner wall of the drive wheel 21 is fixedly connected to the output end of the servo motor 20, the transmission belt 22 meshes with the inner wall of the drive wheel 21, and the inner wall of the driven wheel 23 is fixedly connected to the surface of the drive roller 18, and the inner wall of the driven wheel 23 meshes with the transmission belt 22, driving the pearl cotton to move to the right for continuous punching processing.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: First, place the pearl cotton to be processed above the conveyor belt 19. The pearl cotton is limited by multiple limit baffles 3. Start the servo motor 20 to drive the drive wheel 21 and the transmission belt 22 to rotate. Through the meshing of the transmission belt 22 and the driven wheel 23, the transmission roller 18 is driven to rotate along the inner wall of the fixed frame 1. Through the meshing of the transmission roller 18 and the conveyor belt 19, the pearl cotton is driven to move to the right. Start the hydraulic push rod 5 to push the collection box 7 downward through the connecting plate 6. The movement of the collection box 7 drives the fixed plate 11, the limit shaft 12 and the pressure plate 13 to move downward and contact the pearl cotton. The reaction force generated by the contact pushes the limit shaft 12 to slide upward along the inner wall of the fixed plate 11. At the same time, the spring 14 is squeezed to buffer the punching pressure and press down to fix the pearl cotton. The movement of the collection box 7 drives the hollow punch 8 to move downward and enter the punching groove 9 to punch the pearl cotton. With the support of the top block 10, the waste material can be driven to slide through the inner wall of the hollow punch 8 into the collection box 7 for collection.

[0027] In summary, this punching device for EPE foam production limits the EPE foam using multiple limiting baffles 3. The conveying assembly is activated to drive the EPE foam to the right, and the hydraulic push rod 5 pushes the collection box 7 and the elastic pressing assembly downwards via the connecting plate 6. The elastic pressing assembly, through compression and rebound caused by the reaction force, presses down and fixes the EPE foam, while simultaneously buffering the punching pressure generated by the punching mechanism. The hollow punching mechanism drives the waste material to slide into the collection box 7 for collection. This achieves the goal of automatically collecting waste generated from EPE foam punching, while also facilitating buffered control of the punching force, preventing deviation due to excessive punching pressure on the EPE foam, and greatly improving punching stability. This addresses the problems mentioned in the background section.
