Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton production equipment, and more specifically to an improved pearl cotton slitting device. Background Technology

[0002] Pearl cotton is a new type of environmentally friendly packaging material with many advantages such as water and moisture resistance, shock absorption, sound insulation, heat preservation, good plasticity, high toughness, and strong impact resistance. It is widely used in the packaging of products in various fields such as electronics, ceramics, automobiles, home appliances, and furniture.

[0003] To be suitable for packaging various products, EPE foam typically needs to be slit into various specifications after production using a slitting device. Currently, existing EPE foam slitting devices, such as the one disclosed in authorization announcement number CN212635877U, include a slitting device body. The slitting device body includes an unwinding device, a cutting device, and a rewinding device arranged sequentially from left to right. The cutting device includes a frame, a cutting shaft rotatably connected to the frame, several cutter assemblies evenly distributed along the length of the cutting shaft, a cutter motor fixed to the frame and drivenly connected to one end of the cutting shaft, and front and rear positioning guide rollers rotatably connected to the frame and respectively disposed on opposite sides of the cutting shaft. The cutter assemblies are detachably sleeved on the outside of the cutting shaft, and each cutter assembly includes an annular cutter and annular connecting parts respectively disposed at opposite ends of the cutter.

[0004] This method of cutting EPE foam by using a cutting motor to drive the cutting shaft and rotate the cutting assembly presents significant safety hazards. Furthermore, adding or removing the cutting assembly requires disassembling the cutting shaft and then fitting or removing the annular cutting blade, making installation and disassembly cumbersome. Additionally, this type of cutting assembly reduces the efficiency of equipment downtime and hinders the replacement of EPE foam. Therefore, we provide an improved EPE foam cutting device. Utility Model Content
