Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a cable sheath extruder. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, and characterized by internal current conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, realizing electromagnetic energy conversion. Sheathed cables refer to single-core or multi-core wires with a sheath layer. These cables generally have copper core conductors. In addition to an insulation layer, there is an outer protective layer. The material is polyvinyl chloride (PVC) as the base resin, with added stabilizers, plasticizers, inorganic fillers such as calcium carbonate, additives, auxiliaries, and lubricants. The mixture is prepared by mixing, kneading, and extrusion. During cable production, the material is added to a mixer, heated while stirring, turning the material into a slurry, which is then extruded. The conductors are embedded in the slurry, and after shaping and cooling, the cable is formed.

[0003] Currently, cables are typically processed by extrusion using an extruder. However, during the raw material heating process, the limited heating efficiency of the device makes it difficult for the equipment to completely melt a large amount of raw material in a short time. Some raw material will be mixed in with particles in the slurry, resulting in particles in the cable sheath. This can easily cause the sheath to crack, affecting the cable's lifespan. To address these issues, we have designed a cable sheath extruder. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a cable sheath extruder. Its rotating rod can drive the stirring rod to rotate and agitate the cable sheath raw material, which is conducive to its heating and melting. The unmelted raw material can be filtered on the filter plate, which helps to ensure the extrusion quality of the cable sheath. The cable sheath raw material and cable are pulled out from the outlet of the extruder body and wound on the winding shaft. Under the connection of the second transmission belt, the fan blades can rotate quickly to blow air on the cable sheath raw material and accelerate its cooling. After the extrusion work is completed, the stirring rod and filter plate can be removed for cleaning or replacement, making the operation simple.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Multiple stirring blades are fixedly connected to the side wall of the stirring rod 9, which is beneficial for stirring the cable sheath material. The stirring rod 9 is fixedly connected to the side wall of the rotating rod 8 by screws, which makes it easy to disassemble and remove the stirring rod 9. The first transmission belt 10 is wound between the rotating rod 8 and the output shaft of the first drive motor 5. Under the connection of the first transmission belt 10, the rotating rod 8 can drive the stirring rod 9 to rotate synchronously with the output shaft of the first drive motor 5, so that the stirring rod 9 can perform stirring work.

[0024] A vertical plate 12 is fixedly connected to the upper end of the workbench 1. A winding assembly is installed on the front side wall of the vertical plate 12. The wire body 11 passes through the discharge end of the extruder body 2 and is wound on the winding assembly. The winding assembly includes a rotating roller 14 driven by a second drive motor 13. The second drive motor 13 is installed on the rear side wall of the vertical plate 12 and drives the rotating roller 14 to rotate. A winding shaft 15 that rotates coaxially with the rotating roller 14 is sleeved on the side wall of the rotating roller 14. The outer side wall of the rotating roller 14 is provided with anti-slip texture, which can increase the friction between the rotating roller 14 and the winding shaft 15, so that the winding shaft 15 can be stably sleeved on the outside of the rotating roller 14 and can be pulled out from the rotating roller 14.

[0027] In this utility model, when the cable sheath extruder is working, the winding shaft 15 is sleeved on the rotating roller 14, the conductor body 11 passes through the insertion hole opened on the extruder body 2 and exits from the discharge port of the extruder body 2 and is wound on the winding shaft 15, the cable sheath material is added into the feed funnel 3, the feed funnel 3 and the heating layer in the extruder body 2 can heat the material to melt it, the first drive motor 5 is started to drive the spiral feeding rod 4 to rotate, which can extrude the cable sheath material. Under the connection of the first transmission belt 10, the rotating rod 8 drives the stirring rod 9 to rotate to stir the cable sheath material, which is conducive to its full heating and melting. The unmelted material can be filtered on the filter plate 7, which is conducive to ensuring the extrusion quality of the cable sheath.

[0028] The cable sheath material moves toward the outlet of the extruder body 2 and adheres to the conductor body 11. The material automatically condenses. The second drive motor 13 drives the rotating roller 14 to rotate, causing the winding shaft 15 to rotate and wind the conductor body 11. The cooled cable sheath material and cable are pulled out from the outlet of the extruder body 2 and wound on the winding shaft 15. Under the connection of the second transmission belt 17, the fan blades 16 can rotate quickly to blow air onto the cable sheath material and accelerate its cooling.
