Filter element end cover welding mold with nitrogen fire extinguishing and cooling mechanism

Abstract

The invention relates to the field of machinery, and particularly relates to a filter element end cover welding mold with a nitrogen fire extinguishing and cooling mechanism. The filter element end cover welding mold comprises a mounting mold, wherein a mounting groove is formed in the mounting mold. The filter element end cover welding mold further comprises a frame assembly, a mold rotating assembly and a mold motor assembly, wherein the mold motor assembly is mounted on the frame assembly; the mold motor assembly comprises a driving gear; the mold rotating assembly comprises a supporting shaft, a driven gear and a mold fixing part; the supporting shaft is rotationally connected with the driven gear through a bearing; the driven gear is in transmission connection with the mold fixing part; a channel for conveying nitrogen is formed in the supporting shaft; a nitrogen outlet is formed in the channel; an annular flow guide groove is formed in the mounting mold; the gas outlet directionof the nitrogen outlet is opposite to the annular flow guide groove; nitrogen flow guide channels are further formed in the mounting mold; all the nitrogen flow guide channels are communicated with the annular flow guide channel; gas outlets of the nitrogen flow guide channels are positioned in the mounting groove; and a filter element end cover does not shield the gas outlets. According to the filter element end cover welding mold, nitrogen is introduced into the mold, so that nitrogen can be used for extinguishing fire.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a welding mold for a filter element end cover. Background technique [0002] Filter element end cap welding is a necessary process in the filter production process. The existing filter element end cap welding uses a filter element end cap welding machine to realize the hot-melt welding equipment composed of a plastic filter element and a plastic end cap. The end cover of the filter element is fixed through the welding mold of the end cover of the filter element. The surface of the end face of the filter element is melted by a heater (such as a heating lamp), and then the filter element is inserted to realize the bonding and solidification of the filter element and the end cover of the filter element to form a whole. [0003] The original filter element end cap welding mold technology has the following problems: [0004] 1) The original technology does not have a fire extinguishing functio...
