A processing method for hot-melt connection of ppr hot water plastic pipe fittings

Abstract

The invention relates to a processing method for hot-melt connection of PPR hot water plastic pipe fittings. The hot-melt device is installed through the hinge, the left and right sides of the hot-melt device are symmetrically provided with limit devices, and the lower side of the front end of the installation block is installed with a moving device. The invention provides a PPR hot water plastic pipe fitting hot-melt connection processing method, which can solve the problem of artificially heating and softening the welded part of the pipe fittings before manually welding the plastic pipe fittings. In the case of welding failure and the existing plastic pipe fitting hot-melt connection equipment is welding, directly heat and soften the welding part of the pipe fittings. After the pipe fittings are softened, the plastic pipe fittings are directly welded together through the hot-melt connection equipment. Sliding, leading to problems such as the failure of the pipe fittings to weld.

Description

technical field [0001] The invention relates to the technical field of pipe fitting connection, in particular to a processing method for hot-melt connection of PPR hot water plastic pipe fittings. Background technique [0002] Plastic pipes are generally made of plastic resin as raw material, and are processed by extrusion in a pipe making machine by injection molding. Plastic pipe has the characteristics of light weight, corrosion resistance, easy processing and convenient construction, so it has been widely used in construction projects. With the wide application of plastic pipes, the connecting parts of plastic pipes have also been developed rapidly, among which plastic pipe joints are particularly prominent, and there are a wide variety of products. However, the existing plastic pipe joints generally have high processing costs, resulting in high sales prices. In order to meet the needs of plastic pipe connection, plastic pipe fusion equipment is usually used to join two...

Problems solved by technology

[0005] (2) When the existing plastic pipe fitting hot-melt connection equipment performs hot-melt connection on plastic pipe fittings, it usually directly heats and softens the welded parts of the pipe fittings through the existing pipe fitting hot-melt connection equipment. The fusion connection equipment directly welds the plastic pipe fittings together, and the pipe fittings in the welding process tend to slide relative to each other, resulting in the failure of the pipe fittings welding
