Hot melting connection processing technology for PPR water pipes

Abstract

The invention relates to a hot melting connection processing technology for PPR water pipes. The hot melting connection processing technology for the PPR water pipes adopts a following hot melting connection machine, the hot melting connection machine comprises a bottom plate and fixing devices arranged at the top of the bottom plate, wherein the PPR water pipes are fixed to the fixing devices, and a melting connection device is arranged in the middle of the top of the bottom plate. By cooperation of an air cylinder and fixed pulleys, the air cylinder drives two rotating discs to be synchronously close to each other or away from each other, the pipes are fixed in the rotating discs and can move with the same distance simultaneously, a rotating shaft is utilized for driving two incomplete gears to rotate, so that the two rotating discs simultaneously rotate for the same angle, the skewed condition of the pipes during aligned inserting connection is avoided, and the error is smaller as compared with that of manual operation; and the joints of the pipes are subjected to pressure-maintaining fixation by arc-shaped plates, cooling shaping of the pipes are accelerated, furthermore, the shaking or moving condition of the pipes is avoided, and the two pipes can be subjected to hot melting and pressure-maintaining fixation simultaneously respectively by arrangement of multiple stations.

Description

technical field [0001] The invention relates to the technical field of hot-melt connection of PPR water pipes, in particular to a treatment process for hot-melt connection of PPR water pipes. Background technique [0002] PPR pipe is an updated product of UPVC water supply pipe, aluminum-plastic pipe, PE pipe, PE-X pipe, and PE-RT pipe. Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed. , thus becoming the main force of water pipe materials. The PPR water pipe is connected by hot melting, and the connection process is as follows: inspection→pipe cutting→cleaning the joint part and marking→heating→removing the fusion splicer→aligning→fitting the pipe and correcting it→holding pressure and cooling. [0003] When connecting PPR water pipes at the construction site, the pipes are usually pulled out manually from the die head of the fuser, and then aligned and plugged in. However, there is uncert...

Problems solved by technology

[0003] When connecting PPR water pipes at the construction site, the pipes are usually pulled out manually from the die head of the fuser, and then aligned and plugged in. However, there is uncertainty in the manual operation, and the insertion process is easy to be skewed; During the process, the pipe or pipe fittings must not be moved, and the connection operation of the next joint can only be performed after complete cooling, which reduces the connection efficiency of the pipe fittings
