Description

Technical Field

[0001] The utility model relates to the technical field of cable insulation material extruders, in particular to a cable insulation material extruder. Background Art

[0002] As we all know, the extruder is an important plastic machine. The production and manufacturing of most plastic products can be achieved by extrusion molding. The extruder motor is an important component of the extruder and is the prime mover of the extruder. It provides the large thrust required by the extruder screw. The insulation layer of the cable is generally made of modified polyvinyl chloride, polyethylene and other materials. It is generally made by mixing and extruding polyvinyl chloride resin, inorganic fillers, high-molecular modifiers and other raw materials through a screw extruder. Traditional extruders have the following disadvantages: the existing extruders simply use a stirring rod to stir the material in the feed hopper, which will cause uneven mixing of the material and some material will remain in the feed hopper, resulting in resource waste. Moreover, the current feed hopper cannot evenly transport the material into the interior of the extruder, which will affect product quality.

[0003] To this end, after searching the existing technologies, it was found that the currently disclosed patent technologies, such as a new type of cable insulation material extrusion proposed in publication number CN216001015U, have the following working principles: 1. The material is stirred by a first stirring structure and a second stirring structure, which has the effect of uniformly stirring the material, thereby improving the quality of the cable insulation material; 2. The material remaining on the inner wall of the feed hopper is cleaned by a first cleaning structure and a second cleaning structure, which not only saves resources but also reduces cost investment; 3. The material is uniformly transported to the interior of the extruder by the discharge structure, which has the effect of improving product quality; 4. The discharge structure can be operated by the second stirring structure, which has the effect of reducing the input of the motor, thereby reducing the investment of the cost;

[0004] However, in actual use, when the raw materials enter the feed hole, the feed hole has a small aperture and cannot evenly transport the raw materials into the feed hopper, which easily causes blockage of the raw materials, thereby reducing the efficiency and effect of the cable insulation material extruder, resulting in poor practicality.
