Description

Technical Field

[0001] The utility model relates to the technical field of pearl cotton processing, in particular to a heat sealing device for pearl cotton. Background Art

[0002] Polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene resin. It overcomes the shortcomings of ordinary foamed plastics that are fragile, deformed, and have poor recovery. It has many advantages such as waterproof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.

[0003] When producing pearl cotton, only thinner pearl cotton can be produced. When thicker pearl cotton is needed, two thinner pearl cottons are generally heat-bonded into a thicker pearl cotton, which requires the use of a pearl cotton heat-sealing machine. When the heat-sealing device in the prior art is used, an extrusion shaft is required, and two extrusion shafts are extruded at the same time. However, the position of the extrusion shaft in the prior art is usually fixed. If workers need to extrude pearl cotton of different thicknesses, they need to disassemble the extrusion shaft and re-fix it, which is inconvenient for workers to move and adjust it, increases the work intensity of the workers, and reduces the work efficiency of the heat-sealing device, which is very troublesome to use.

[0004] For this reason, we propose a heat sealing device for pearl cotton. Utility Model Content
