Method for thermal shrinkage packaging of battery

Abstract

A method for thermal shrinkage packaging of a battery comprises a rack, a transmission structure and a thermal shrinkage drying tunnel, and the transmission structure and the thermal shrinkage drying tunnel are installed on the rack; the transmission structure comprises a metal mesh belt, and the thermal shrinkage drying tunnel comprises a thermal shrinkage main drying tunnel; the metal mesh belt penetrates through the thermal shrinkage main drying tunnel of the thermal shrinkage drying tunnel; the thermal shrinkage drying tunnel comprises a preheating drying tunnel, a main drying tunnel and a heat preservation drying tunnel which are connected in sequence, and the main drying tunnel comprises a heating cover; an electric heater, fins, a heat shielding plate, a radiant plate and a main drying tunnel thermocouple are fixedly arranged in the heating cover; the fins are fixedly arranged above the electric heater, and the heat shielding plate is fixedly arranged above the fins; and an installation opening is formed in the lower portion of the radiant plate, and the main drying tunnel thermocouple is fixedly arranged on the inner wall of the heating cover. The preheating drying tunnel comprises a preheating drying tunnel thermocouple fixedly arranged on the inner wall of the bottom. According to the method, a draught fan, an air duct, accessories of the air duct and a drying tunnel air outlet are omitted, and packaged pieces are heated in a radiation and natural convection mode; and energy losses caused by the heat flow rate are reduced, and cost reduction, energy conservation and emission reduction are facilitated.

Description

technical field [0001] The invention relates to the field of shrink packaging, in particular to a method for shrink packaging of batteries. Background technique [0002] The main function of the heat shrink packaging device is to do heat shrink film packaging for batteries, toys, electrical appliances, stationery, hardware tools, daily necessities and other products. Wrapping the product or package tightly is not only convenient to carry, but also can fully display the appearance of the product, improve the display and sale of the product, and increase the beauty and sense of value. Therefore, heat shrinkable packaging is widely used. [0003] The structure and manufacturing process of the existing heat-shrinking device for batteries are relatively complex, requiring the cooperation of various structures such as fans and air ducts to complete the function of shrinking the heat-shrinkable plastic film by heat. The manufacturing requirements and manufacturing costs are high, a...

[0003] The structure and manufacturing process of the existing heat-shrinking device for batteries are relatively complex, requiring the cooperation of various structures such as fans and air ducts to complete the function of shrinking the heat-shrinkable plastic film by heat. The manufacturing requirements and manufacturing costs are high, and the use of fans will bring Air flow will also cause a certain amount of energy loss. How to improve the method of battery heat shrink packaging, simplify the device structure, improve the efficiency and quality of heat shrink packaging, and reduce manufacturing and use costs have become the direction of further improvement.
