Description

Technical Field

[0001] The present application relates to the technical field of MPP power pipe production, and in particular to a raw material mixing device for MPP power pipe production. Background Art

[0002] MPP pipe, also known as MPP power cable protection pipe, is available in trenchless and trenchless types. MPP trenchless pipe is also known as MPP jacking pipe or pull-out pipe. MPP pipe uses modified polypropylene as its primary raw material. During the MPP pipe production process, a raw material mixing device is often required to mix the modified polypropylene with other auxiliary materials before injection molding.

[0003] For example, the Chinese utility model patent with the announcement number CN219543700U discloses a raw material mixing device for the production of MPP power pipes, which belongs to the technical field of power pipe production equipment, specifically a raw material mixing device for the production of MPP power pipes. The utility model sets a limit box inside the main body and extends the lower end of the feed port into the interior thereof. The first bevel gear can drive the adjacent transmission gear to rotate through the second bevel gear, thereby driving the rolling roller to grind the material into powder, and the scraper scrapes the material off and mixes it with other materials. The simple structure can effectively prevent some agglomerated materials from affecting the processing quality. At the same time, the powdered materials can greatly improve the mixing efficiency to ensure work efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that most of the raw material mixing devices used in the production of MPP power pipes in the related technologies can only mix the raw materials in a single direction, resulting in uneven mixing of the raw materials and greatly reducing the mixing efficiency of the raw materials.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
