[0001] The utility model belongs to the technical field of heat sealing devices, and in particular relates to a heat sealing device that is easy to adjust. Background Art

[0002] Pearl cotton 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 has good chemical resistance and is an ideal substitute for traditional packaging materials. When making pearl cotton in the existing technology, it is necessary to heat it to make it fit each other, which can increase the thickness of the pearl cotton and make it more restorative. At this time, a heat sealing device is needed to make it.

[0003] However, the position of the extrusion shaft of the heat sealing device in the prior art is usually fixed. When workers extrude the 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, reducing the working efficiency of the heat sealing device. In addition, the flatness of the pearl cotton after heat sealing cannot be guaranteed, affecting the subsequent cutting work. A heat sealing device that is easy to adjust is now provided to alleviate the above-mentioned problems. Summary of the invention
