Hot press molding process for air column bag of one-way air valve

Abstract

The invention discloses a hot press molding process for an air column bag of a one-way air valve, and relates to the field of air column bag production. The hot press molding process for the air column bag is implemented by a hot press molding device which comprises a bottom plate, guide columns are fixed to the four corners of the top of the bottom plate, a top plate is fixed to the tops of the guide columns, an air cylinder is fixed to the bottom of the top plate, and a pressing plate is fixed to the bottom end of the air cylinder. The distance between metal plates is adjusted, then the position of a heat sealing limiting strip can be adjusted, the practicability of the device is improved, heat conduction oil in a heat preservation frame is heated through an electric heating wire, heat is transferred to a metal frame and the metal plates, heat dissipation is prevented from being fast, and people can be prevented from being scalded by touching the device; by adjusting the position of a limiting ring on a carrier roller, a plastic film can be prevented from deviating in the conveying process, a rubber wheel can make contact with the carrier roller in the hot pressing process, the plastic film can be straight on the two sides of the device, wrinkles of the plastic film in the heat sealing process are avoided, and the heat sealing precision and efficiency are improved.

Description

technical field [0001] The invention relates to the field of air column bag production, in particular to a single-valve air column bag thermocompression forming process. Background technique [0002] Air column bags, also known as buffer air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are new packaging materials filled with natural air. It has the characteristics of stretch resistance and balance, and has good surface printability. It is a medical-grade substrate. Through continuous lamination, it forms an airtight inflatable column. [0003] Most of the currently used air column bags are made by hot pressing forming process, but when in use, the device is not convenient to adjust the indentation distance of the air column bag, resulting in poor practicability of the device, and the device is made of metal , due to the thermal conductivity of metal, it is easy to cause the whole device to be heated, and it is easy to cause the operator to...
