Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe cutting and processing, in particular to a traction device for PE pipe cutting and processing. Background Art

[0002] At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all have a place, among which the strong development momentum of PE pipes is the most remarkable. PE pipes are widely used, among which water pipes and gas pipes are their two largest application markets.

[0003] The existing PE pipe cutting traction device can only pull the PE pipe to be cut forward, but cannot control the pulling distance of the PE pipe, so it is inconvenient to adjust the cutting length of the PE pipe. In addition, the PE pipe cannot be fixed during the PE pipe pulling process, which causes the PE pipe to be easily pressed down by the cutting blade and shifted in position during cutting, resulting in an error in the cutting length of the PE pipe. Therefore, a traction device for PE pipe cutting is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problems that the traction device cannot control the traction distance of the PE pipe, is inconvenient to adjust the cutting length of the PE pipe, and cannot fix the PE pipe during cutting. When the PE pipe is cut, it is easy to be pressed down by the cutting blade and the position is offset, resulting in errors in the cutting length of the PE pipe.
