Interlocking and protective device for hot pressing plate of refrigerator van plate and application method thereof

Abstract

The invention relates to the technical field of protection, in particular to an interlocking and protective device for a hot pressing plate of a refrigerator van plate and an application method thereof. The interlocking and protective device for the hot pressing plate of the refrigerator van plate comprises a hot pressing plate machine body. The inner wall of a mold cavity of the hot pressing plate machine body is connected with an upper template, the inner bottom wall of the mold cavity of the hot pressing plate machine body is connected with a lower template matched with the upper template through a drive mechanism, and the upper template is located above the lower template. Infrared ray safe light curtains are arranged on the entrance of the mold cavity of the hot pressing plate machinebody, and the hot pressing plate machine body is provided with an electrical control system and a gas circuit control system. The interlocking and protective device for the hot pressing plate of therefrigerator van plate and the application method thereof enable safety facilities in working area of the hot pressing plate machine body meet the requirement of safety production law, so as to risk value reduce to zero. The interlocking and protective device adopts the method of the photoelectric combination, automatic control, human entry protection and human exit manual reset and starting up torealize the five-stage interlocking protection, guarantee the essential safety, and guarantee the physical health of operators.

Description

technical field [0001] The invention relates to the technical field of protection, in particular to an interlocking protection device for a hot-pressed plate of a refrigerated carriage and a method for using the same. Background technique [0002] The refrigerated car plate hot pressing machine (applicable to refrigerated car plate press machine, large plate shelter press machine, van car plate, fresh car box body equipment) aims to provide a refrigerated car composite plate pressing equipment. The equipment of the whole production line includes plate making presses, automatic glue spraying machines and carriage assembly frames. Among them, the plate making hot press machine is used to ensure the rapid forming of the refrigerated compartment plate and the formed compartment plate does not have cavities, layer separation, and uneven waves caused by incomplete compaction, so as to meet the insulation requirements and ensure the flatness and strength of the compartment plate, e...

AI Technical Summary

Problems solved by technology

[0003] The company uses a hot press machine for refrigerated car panel paneling. Glue overflows during paneling work, resulting in the need to manually clean the polyurethane glue on the upper formwork (fixed) every month. The cleaning frequency is 2 times per month. Due to the technical requirements for the initial equipment, there is no Clarify the requirement that operators need to enter the mold cavity to clean up the remaining glue. After analysis, the glue cleaning operation is a restricted space operation, and the equipment itself is not designed with interlock protection, which is a high risk and needs to be rectified immediately
