Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a two-stroke extrusion device for cable material. Background Technology

[0002] Plastics used for the insulation and sheathing of wires and cables are commonly known as cable materials, which include various types such as rubber, plastics, and nylon. Cable material manufacturers serve cable manufacturers as their customers; as long as there is demand for wires and cables, there will be a market for cable materials. The outer insulation layer of a cable is formed by extrusion and cooling during the production process.

[0003] In the extrusion process of cable insulation, plastic granules are melted and molded into the required shape and size of the outer insulation layer through an extruder. However, existing two-stroke extrusion equipment does not have a pre-treatment stage during feeding, resulting in agglomerated material entering the extrusion equipment directly. This agglomerated material accumulates inside the equipment, which can easily cause blockage of the extrusion channel. This not only affects the stability of equipment operation but also reduces the extrusion molding quality of cable products, ultimately leading to decreased processing efficiency and a lower product qualification rate. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a two-stroke extrusion device for cable material, which has the following advantages:

[0016] (1) In this utility model, after the material enters the machine body through the feed box, the motor drives the first rotating rod to rotate, and at the same time drives the first gear to mesh with the second gear, so that the second rotating rod rotates synchronously; the spiral blades on the two rotating rods perform preliminary stirring and mixing of the material. At the same time, the second rotating rod drives the first connecting rod and its first dispersing tooth to rotate through the first synchronous wheel and the first synchronous belt. The first connecting rod then drives the second connecting rod and the second dispersing tooth to rotate through the second synchronous wheel and the second synchronous belt. Through the synergistic effect of the spiral blades and the double dispersing teeth, the material is fully crushed and homogenized before entering the extrusion zone, effectively preventing the agglomerated material from entering the extrusion equipment. Finally, the homogenized material is extruded and formed through the extrusion head of the machine body, which improves the pretreatment effect of the material and avoids the equipment blockage problem caused by the agglomerated material, thereby improving the processing efficiency and product qualification rate.

[0017] (2) In this utility model, the electric push rod on the side of the feed box drives the push plate to move, which drives the connected baffle to move synchronously, so that the feed box is fully opened to allow material to be added; after the feeding is completed, the electric push rod moves in the opposite direction to reset the baffle. When the end of the baffle is tightly attached to the inner wall of the feed box, an effective sealing structure is formed, realizing the controllable opening and closing of the feed box. This ensures the smooth addition of material and effectively prevents material from splashing during the processing, improving the sealing performance and operational safety of the equipment, while also enhancing the practicality and reliability of the overall process.
