Description

Technical Field

[0001] This utility model relates to a hot melt welding machine, specifically a hot melt welding machine for plastic valves, and belongs to the field of plastic valve processing technology. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. Due to actual usage needs, two-way plastic valves need to be improved into three-way valves, which requires processing and welding.

[0003] A fixing device for processing and welding plastic valves, disclosed in Chinese Patent Application Publication CN212795967U, involves fitting one end of a plastic valve onto the outside of a rotating barrel. An air pipe is then connected to a booster, allowing compressed air to enter the pneumatic cylinder through the air pipe, a tee connector, and a delivery pipe. The compressed air pushes a piston within the rotating barrel, which in turn moves a sliding rod and positioning plates. These three positioning plates move in three directions, pressing against the inner wall of the plastic valve for fixation. By adjusting the amount of compressed air, the movement distance of the piston can be controlled, and the movement of the sliding rod and positioning plates can be adjusted to accommodate plastic valves of different diameters, improving its adaptability. The internal fixing method avoids the problem of valve displacement caused by collisions during use due to the large size of traditional external fixing methods, thus ensuring the quality of valve welding.

[0004] The above patented solutions can fix plastic valves of different diameters, improving their adaptability. However, the device requires the air pipe to be connected to an external booster, and the air pipe is prone to tangling, which leads to high maintenance difficulty and inconvenience in use.

[0005] Therefore, a plastic valve hot melt welding machine is proposed here. Utility Model Content
