Foaming device and foaming system comprising same

Abstract

The invention discloses a foaming device. The foaming device comprises a supporting assembly, a compression joint assembly and a locking assembly, wherein the supporting assembly comprises a base and a supporting part arranged on the base; the shape of a supporting surface of the supporting part is matched with that of one side, close to the supporting surface, of a foaming part; the compression joint assembly is arranged on the supporting assembly; the shape of a compression joint surface is matched with that of one side, far away from the supporting surface, of the foaming part; the supporting surface and the compression joint surface are arranged at interval, and an assembling space of the foaming assembly is formed between the supporting surface and the compression joint surface; the locking assembly is used for fixing the compression joint assembly on the supporting assembly. The foaming device disclosed by the invention can be used for carrying out compression joint on the foaming part very well and the foaming part is effectively prevented from deformation; furthermore, the foaming part can be carried and moved to a foaming machine, so that the foaming part can be stably and reliably transferred and transported, produced and assembled, and the labor intensity is alleviated. The invention further provides a foaming system comprising the foaming device.

Description

technical field [0001] The invention relates to the technical field of foaming equipment, in particular to a foaming device for a refrigeration unit, and also to a foaming system including the foaming device. Background technique [0002] The land-use transport refrigeration unit belongs to the series of refrigerated refrigeration units. The temperature of the refrigeration working condition is low, and the ordinary sponge insulation method can no longer meet the temperature requirements of the unit for the refrigeration working condition. Therefore, the mode of foam filling is used for heat insulation between the interior of the compartment and the exterior of the compartment of the existing land-use transport refrigeration unit. [0003] The refrigeration unit formed by foam filling has multiple foam parts, that is, multiple foam parts are assembled (connected by welding or bolts) to form a refrigeration unit with accommodating space, and each foam part has a foam cavity. ...

AI Technical Summary

Problems solved by technology

[0003] The refrigeration unit formed by foam filling has multiple foam parts, that is, multiple foam parts are assembled (connected by welding or bolts) to form a refrigeration unit with accommodating space, and each foam part has a foam cavity. Since the foam filling needs to fill the entire foaming cavity between the inner side and the outer side of the box, a relatively high pressure is required. However, most of the foaming cavities of the existing foaming parts have irregular structures, and most of the inside of the box have slopes. The overall structure of the foamed parts is complex, and it is difficult to crimp when foaming. Under the action of large foaming pressure, the sheet metal parts of the foamed parts are easy to bulge and deform
