Abstract

The invention discloses a welding device for a plastic pipe. The technical scheme is characterized in that the welding device comprises a rack, a pipe clamp jig used for clamping a main pipe, a first clamp used for clamping a pipe welding head and a second clamp used for clamping branch pipes, which are arranged on the rack, a hot-melting heating device, a linear motion system for realizing the relative axial motion of the pipe clamp jig and the first clamp, and a three-axis motion system used for enabling the second clamp to move towards the sidewall of the main pipe and realizing the entrance of the hot-melting heating device to the axial directions of the branch pipes or the separation of the hot-melting heating device from the axial directions of the branch pipes, wherein the hot-melting heating device has two working state, the first one is that the hot-melting heating device is used for heating the sidewall of the main pipe and the end heads of the branch pipes respectively, and the second one is the hot-melting heating device is used for heating the sidewall of the main pipe and the sidewall of the pipe welding head respectively. Hot-melting heating among the same pipelines can be realized on one device, hot-melting heating for the pipe welding head and the main pipe can be realized, and hot-melting heating for the plurality of branch pipes arranged on the main pipe can be realized; and the hot-melting welding device is automatic in welding, high in efficiency, high in welding quality, and easy for working personnel to operate.

Description

technical field [0001] The invention relates to the technical field of connection and joining of plastic molded parts, more specifically, it relates to a plastic pipe welding device. Background technique [0002] PE pipes, HDPE pipes, PP pipes, PVC pipes, PC pipes, PPH pipes and other plastic pipes will use pipe welding joints when they are butt jointed. The diameter of the inner ring of the pipe welding joint is equal to the diameter of the outer ring of the plastic pipes. The split pipes are connected to each other. To realize the pipe connection, a hot-melt welding machine is needed to perform hot-melt butt welding on the pipes through the hot-melt welding machine. [0003] The Chinese patent application number 201420668231.5 discloses a plastic pipe hot-melt welding machine, which includes a base, several displacement clamping structures and a welding plate structure. There is a secondary welding structure on the side of the plate structure. The secondary welding struct...
