[0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes, and metal flexible hoses. Metal corrugated pipes are mainly used to compensate for pipeline thermal deformation, damping, and absorbing pipeline settlement deformation, and are widely used in petrochemical, instrumentation, aerospace, chemical, power, cement, and metallurgical industries. Corrugated pipes made of plastics and other materials play an irreplaceable role in media transportation, power wiring, machine tools, and home appliances.

[0003] Corrugated pipes are usually made of high-density polyethylene. Depending on the application and production requirements, the factory will mix different types of plastic granules in a certain proportion, and then heat and melt them in an extruder before injecting them into the mold.

[0004] However, the lack of a metering device in the existing technology makes it difficult to control the mixing ratio and the quantity of materials dispensed. In order to solve the problem of the lack of a metering device in the existing technology, this application sets up components such as racks and gears, so that the storage hopper can drive the gears and pointers to rotate by moving up and down, thereby achieving the effect of displaying the quantity of materials dispensed. Therefore, a new solution is needed to solve this problem. Utility Model Content
