Heat-seal forming equipment for food packaging bag and heat-seal forming method of heat-seal forming equipment

Abstract

The invention relates to heat-seal forming equipment for a food packaging bag and a heat-seal forming method of the heat-seal forming equipment. The heat-seal forming equipment comprises a workbench, a fixing device and a moving device; the fixing device comprises a supporting frame, a fixing plate, a cylindrical hollow barrel, a limiting hole, an air suction frame, a first circular through hole and a discharging frame. Through cooperation of the workbench, the fixing device and the moving device, firstly, the food packaging bag filled with food is placed on the fixing device, the food packaging bag is limited and fixed through the fixing device, at the moment, the designed moving device is used for firstly clamping the food packaging bag filled with the food, air blowing is conducted after clamping, after air blowing is completed, the food packaging bag filled with the food is subjected to heat sealing, and finally, the redundant food packaging bag in the sealing position is cut, so that the working efficiency of the machine is improved.

Description

technical field [0001] The invention relates to the technical field of heat-sealing processing of food packaging bags, in particular to a food packaging bag heat-sealing forming equipment and a heat-sealing forming method thereof. Background technique [0002] Food packaging bag is a kind of packaging design. In order to keep fresh and store food in daily life, product packaging bags are produced. Food packaging bags refer to film containers that are directly in contact with food and are used to hold and protect food. Food packaging bags can be divided into: ordinary food packaging bags, vacuum food packaging bags, inflatable food packaging bags, boiled food packaging bags, steamed food packaging bags and functional food packaging bags according to their application range. After the food, it needs to be sealed and heat sealing is mostly used. Heat sealing is to heat the sealing material in a certain way to make it reach a viscous state and then pressurize it to make it stick...

AI Technical Summary

Problems solved by technology

[0004] (1) During the heat-sealing process of traditional food packaging bags, due to the structural limitations of food packaging bags, when heat-sealing food packaging bags filled with food, the machinery cannot quickly seal the food packaging bags filled with food. The bag is inflated and heat-sealed, reducing the efficiency of the machine when heat-sealing the food-filled food bag

[0005] (2) During the heat-sealing process of traditional food packaging bags, due to the structural limitations of food packaging bags, after heat-sealing the food packaging bags filled with food, the excess part of the seal cannot be separated from the food packaging bags. The separation is complete, and Xu Ya performs a second separation, which reduces the working efficiency of the machine
