Hot melt connection mechanism for novel plastic pipe

Abstract

The invention discloses a hot melt connection mechanism for a novel plastic pipe. Anti-scalding plates which are parallel to a heat plate and can get close to or away from the heat plate are arranged on supports on two sides of the heat plate; through holes matched with melt heads are formed in corresponding positions on the anti-scalding plates; the end part of the pipe penetrates through the through holes and is in contact with the melt heads. Aiming at the defects of frequency scalding accidents caused by easily careless operation of a conventional hot melt machine in the market, the hot melt connection mechanism for the novel plastic pipe is improved and optimized for corresponding structures. When the hot melt connection mechanism for the novel plastic pipe is used for connecting the pipe, the end part of a pipe fitting penetrates through the through holes in the anti-scalding plates for pipe orifice melting; the anti-scalding plates are positioned between hands of an operator and the heat plate; in case of misoperation caused by improper force, the operator pushes the anti-scalding plates to be in contact with the heat plate or the melt heads, to avoid direct contact between the hands and the heat plate or the melt heads, thus avoiding a scalding accident and improving the safety in the working process.

Description

technical field [0001] The invention belongs to the field of plastic pipe processing equipment, and in particular relates to a novel plastic pipe hot-melt connection mechanism. Background technique [0002] New plastic pipes such as PB pipes and PE-RT pipes are more and more widely used in the field of pipeline construction due to their excellent performance in terms of service life and corrosion resistance. The connection of plastic pipes is mainly realized by a hot melter. The outer wall of one end of the pipe and the inner wall of the other end of the two pipes to be connected are respectively passed through a matching hot melter in the heated state. The contact extrusion of the melting head is melted, and then the two ends are quickly sleeved together, and the connection of the two pipes is realized after cooling. [0003] At present, the above-mentioned method of connecting plastic pipes through a fuser mainly has the following problems: during the construction process...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly the following problems in the above-mentioned method of connecting plastic pipes through a hot melter: during the construction process, the temperature of the hot plate and the melting head of the hot melter is very high, and safety accidents such as burns of operators are very likely to occur
