Bubble suction system of refrigerator liner vacuum forming machine

Abstract

The invention discloses a refrigerator liner vacuum forming machine bubble suction system which comprises an equipment sealing box, the equipment sealing box is connected to a forming machine rack in a lifting mode, a cooling bubble suction assembly is installed on the top of the equipment sealing box, and the cooling bubble suction assembly conducts switching of air blowing cooling and forming bubble suction on the interior of the equipment sealing box through a control valve set. According to the foam sucking and cooling device, foam sucking and cooling process production is completed on a plate through one cooling foam sucking assembly, the complex structure of traditional equipment is greatly reduced, foam sucking and cooling are switched through the control valve set, the high-pressure fan is always kept in the working state in the production process, quick response of actions can be achieved, and the production efficiency is improved. The production efficiency and the forming effect are improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum forming machines for refrigerator inner liner, in particular to a foam absorption system of a refrigerator liner vacuum forming machine. Background technique [0002] The refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. The door of the refrigerator, wherein the refrigerator door includes the outer shell, the insulation layer, the inner tank, etc. [0003] The existing refrigerator liner is usually rapidly formed by a molding machine. During the molding process of the refrigerator liner by the molding machine, the sealing box needs to move down to seal the liner plate, and then the molding of the inner liner is realized by means of absorbing bubbles. When the inner tank is formed, the plate needs to be cooled and cooled. The existing bubble sucti...

AI Technical Summary

Problems solved by technology

[0003] Existing refrigerator liners are usually rapidly molded by a forming machine. During the molding process of the refrigerator liner by the forming machine, the sealing box needs to move downward to seal the inner liner plate, and then the inner liner is formed by sucking bubbles. After the liner is formed, it is necessary to cool down the plate. The existing suction bubble uses a vacuum pump to pump air, and another cooling mechanism is required to complete the cooling, resulting in complex equipment structure and high production costs.
