Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production equipment, in particular to a traction auxiliary device for MPP pipeline production. Background Art

[0002] MPP pipe is a plastic pipe, which is mainly used in the pipeline system of power, communication, municipal and other fields. MPP pipe has the characteristics of high temperature resistance, corrosion resistance, aging resistance, high compressive strength and long service life. It is widely used in various fields. The production of MPP pipe requires the use of extruders, cooling equipment, cutting equipment, inspection equipment and packaging equipment. Among them, extruders and cooling equipment are core equipment. In the production process, the raw materials are first mixed in a certain proportion, and an appropriate amount of additives are added and stirred evenly. Then the mixed materials are put into the extruder, heated, melted and extruded to form the shape of the pipe. Then the newly extruded pipe is put into the cooling equipment to cool it down quickly to prevent deformation and shrinkage. Then the cooling equipment is used to cut the cooled pipe to the required length.

[0003] When cutting the MPP pipe, it is necessary to use traction equipment to pull the MPP pipe, so as to achieve a fixed-distance cutting of the MPP pipe. Generally, a chain-type traction equipment is used, in which a bump is installed on the chain, and the friction between the bump and the pipe is used to transport the pipe. In this process, the bump will be worn after long-term use. When replacing it, the entire bump needs to be replaced, which causes a certain waste of production materials. Utility Model Content

Two plug blocks 16 are fixedly installed at the lower end of the rubber block 8, and a second screw groove 17 is provided in the plug block 16. The plug block 16 is inserted and installed in the corresponding telescopic groove 13. The rubber block 8 is movably installed on the mounting seat 6 through the plug block 16 and the connecting screw 9, so that the rubber block 8 can be used.
