Automatic aluminum foil coating equipment of refrigerator air return pipe module

Abstract

The invention relates to the technical field of machining of refrigerator equipment, in particular to automatic aluminum foil coating equipment of a refrigerator air return pipe module. The equipment comprises an equipment main machine and an electric control device; a guide rail is fixed on a machine body of the main machine, and is provided with a coating device for sliding along the guide rail; a clamping device for clamping the end parts of an aluminum pipe, a copper pipe and an aluminum foil is fixed at the back end of the machine body; and with the moving direction of the coating device during coating as the front side, the coating module comprises a separator at the front end for horizontally separating the aluminum pipe from a bobbin by a period of distance, a unwinding wheel for the aluminum foil, and a guide mechanism, an aluminum pipe coating mechanism, a compacted aluminum pipe primary pressing wheel, a module coating mechanism and final pressing of a compaction module coating state arranged in sequence. The equipment is used for automatically coating the aluminum foil on the air return pipe module, can realize the flow operation of once coating of the aluminum foil on the air return pipe module, greatly improves the production efficiency and the machining precision, and can save labors.

Description

technical field [0001] The invention relates to the technical field of refrigerator equipment processing, in particular to a processing equipment for automatically pasting and wrapping the outer surface of an air return pipe assembly of a refrigerator with aluminum foil. Background technique [0002] In the refrigeration system of a refrigerator, the refrigeration components are mainly composed of a compressor, a condenser, a filter, a throttling device (referred to as a capillary), an evaporator, and a return air pipe. The low-temperature and low-pressure refrigerant evaporates in the evaporator from liquid to gas, and at the same time absorbs heat to achieve the cooling effect; the refrigerant enters the compressor from the return air pipe and is compressed into a high-pressure and high-temperature gas, and then radiates heat to the outside through the condenser, and condenses into a liquid ; The refrigerant passes through the filter to filter out impurities such as water ...

AI Technical Summary

Problems solved by technology

[0004] Patent application number 201610080179.5 discloses an automatic wrapping device for the air return pipe of a refrigerator with aluminum foil. By automatically wrapping the aluminum foil for the air return pipe, the flow-through operation of wrapping the aluminum foil for the return air pipe can be realized. However, this patent only discloses the first wrapping of the air return pipe of the refrigerator. After wrapping, the wrapping together with the capillary needs to be done manually or by other wrapping equipment. The wrapping of the refrigerator return air pipe assembly cannot be completed at one time, and the production efficiency is still low and the labor intensity is still high.
