Description
Technical Field
[0001] This utility model relates to the technical field of pearl cotton cutting equipment, specifically a cutting device for pearl cotton production and processing. Background Technology
[0002] Pearl cotton, also known as EPE pearl cotton or polyethylene foam, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It has many advantages such as water and moisture resistance, shock absorption, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials. During the production process, pearl cotton needs to be cut into pieces according to its intended use.
[0003] A search revealed a patent, CN220719634U, which discloses a cutting device for processing pearl cotton sheets. The device includes a frame containing a cylinder, platinum wire, and a conveyor belt. A first hollow tube, a second hollow tube, and a second bolt are located on the right side of the frame, while a first roller and a second roller are located on the left side. An electric motor is mounted at one end of the first roller, and two sets of first bases are located on the left side of the first roller. Each first base has multiple sets of circular holes, and a storage rod is positioned between the first bases. This invention, through its platinum wire and other structures, can quickly cut pearl cotton. The platinum wire heats up when energized, melting the pearl cotton and resulting in a clean cut at a high speed. The second hollow tube and other structures allow for adjustment of the size of the pearl cotton sheet storage box, facilitating subsequent collection by workers.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] The aforementioned comparative document describes cutting EPE foam sheets into pieces using heated platinum wires. However, in reality, EPE foam sheets need to be cut to sizes suitable for specific applications. Larger EPE foam sheets require cutting into multiple pieces. The aforementioned comparative document only allows for one cutting of the EPE foam sheet at a time, reducing the efficiency of cutting EPE foam. Therefore, there is an urgent need in the art to improve the cutting device used for EPE foam production and processing, thereby overcoming the shortcomings of the prior art. Utility Model Content

A connecting plate 21 is fixedly installed on the upper part of the second sliding block 19. An elastic element 22 with elasticity is provided between the connecting plate 21 and the upper part of the pressing plate 10. A second adjusting groove 23 communicating with the second sliding groove 20 is opened on the side of the second fixed frame 18. A second locking bolt 24 with one end threaded to the side of the second sliding block 19 is inserted through the second adjusting groove 23. The second sliding groove 20 passes through both ends of the second fixed frame 18.
