Abstract

The invention discloses a preheating device for refrigerator door foaming. The preheating device comprises an outer shell; multiple heating chambers are transversely arranged in the outer shell in sequence; second heaters are arranged in all the heating chambers; all the heating chambers are separated through separation plates; and grooves are formed in the side walls of one sides of all the heating chambers. Electric extension rods and fixing heads are provided for fixing workpieces; pressure sensors are provided for sensing pressure; when the pressure exceeds a preset value, the electric extension rods are stopped elongating to prevent damage of the workpieces caused by higher pressure; cleaning brushes are provided for cleaning the surfaces of the workpieces to achieve subsequent machining; temperature sensors are provided; when the workpieces are heated to reach a preset value, the workpieces in the corresponding heating chambers are stopped working to prompt the preheating completion to workers; and hydropresses are provided for driving the cleaning brushes to move up and down to increase the cleaning area.

Description

technical field [0001] The invention relates to a preheating device, in particular to a preheating device for refrigerator door foaming. Background technique [0002] Foaming is one of the necessary processes in the manufacture of refrigerators. Before foaming, the refrigerator parts need to be preheated to facilitate the quality of subsequent foaming. However, the current waste heat device does not clean the surface of the refrigerator, which may cause foaming during foaming. The quality of foaming is not good, so we make improvements and propose a preheating device for foaming refrigerator doors. Contents of the invention [0003] In order to solve the defect that the waste heat device in the prior art does not clean the surface of the refrigerator, the present invention provides a preheating device for foaming the refrigerator door. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical soluti...
