Description

Raw material mixing device for producing rigid polyvinyl chloride cable tube Technical Field The utility model relates to the technical field of pipe production, in particular to a raw material mixing device for producing a rigid polyvinyl chloride cable pipe. Background The pipe is the material used for making the pipe fitting. Different pipes are needed for different pipes, and the quality of the pipes is directly determined by the quality of the pipes. The pipe is used for building engineering, power plant, chemical plant, etc. And the power tube is one of many tubes. The power tube is a product which is coated inside and outside by PE (polyethylene) hot dip molding or epoxy resin, and has excellent corrosion resistance. Meanwhile, the coating has good electrical insulation, and no electric corrosion is generated. For example, in chinese patent publication No. CN220995053U, a raw material mixing device for producing a cable tube is disclosed, which comprises a mixing drum, a cover plate is fixed on the top of the mixing drum, a material injection tube is fixedly penetrated on the cover plate, the mixing drum is mutually communicated with the material injection tube, a plurality of separating hoppers are sequentially fixed in the mixing drum from top to bottom, a material conveying tube is fixedly communicated with the bottom of each separating hopper, two reinforcing plates are fixed on the outer wall of the material conveying tube, and the heights of a plurality of blanking stirring assemblies can be regulated and controlled by using two hydraulic cylinders, so that the blanking stirring assemblies are matched with the material conveying tube; In the above-mentioned scheme, though can drive the second belt pulley through driving motor and drive first belt pulley rotation with the help of driving belt for stirring subassembly is rotatory, carries out the mixing stirring to the raw materials, but only set up a notes material tube on the apron, make when reinforced, need add another raw materials from notes material tube to add after mixing drum is inside earlier, if the raw materials kind of mixing is more, can reduce the efficiency that the raw materials mixes by a wide margin, the multilayer stirring subassembly that mixing drum inside set up also further increases the time that the raw materials mix simultaneously.
