Description

Technical Field

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

[0002] The pipe extruder is mainly used to produce hollow pipes. Generally, the material enters the extruder first. After batching and mixing, the screw transmission drives the material forward. After foaming, cooling and shaping, the pipe to be processed is formed. At the end of the extruder, there is usually a cutting device for cutting the pipe. The cutting device includes a motor, a first cylinder, etc., so that the formed pipe can be segmented. The other side of the cutting device is provided with a transmission mechanism for transmitting the cut pipe to the placement. After the extruder transmits the pipe to the cutting device at a constant speed, it is cut by the cutting device. When the cutting is completed, the transmission mechanism transports the cut pipe to the placement area, and the extruder transports the pipe to be cut to the cutting device for the next cutting, and this cycle is repeated. During use, only a single length of pipe can be cut. When pipes of different lengths are required, the machine needs to be replaced, or the length of the pipe needs to be measured again to determine the position of the tool cutting. This method is more cumbersome and the cutting efficiency is low. Therefore, there is an urgent need for a PE pipe cutting device that is not only simple to operate, but also suitable for cutting pipes of different lengths and can improve cutting efficiency.
