Abstract
Description
Technical Field
[0001] The utility model relates to a three-layer cable co-extrusion device with stable core eccentricity, belonging to the technical field of co-extrusion equipment. Background Art
[0002] The manufacturing of wires and cables differs significantly from the production of most electromechanical products. Electromechanical products are typically assembled from parts into components, and then from multiple components into a single product, with the product measured by unit or piece. Wires and cables are primarily measured by length. All wires and cables begin with conductor processing, and are then layered with insulation, shielding, cabling, and sheathing to create a finished product.
[0003] A Chinese patent discloses a three-layer co-extrusion dry-process cross-linked cable production device, with publication number CN217061605U. The technical solution disclosed in the patent document is as follows: it includes a connecting base, a pressure cylinder, an extrusion piston, an electric push rod, a feed port, a material check valve, a feed mechanism, a finished product check valve, a discharge port and an extrusion interface, wherein: the pressure cylinder is installed inside the connecting base by bolts, and the extrusion piston is embedded in the inside of the pressure cylinder, one end of the electric push rod is installed on one end of the extrusion piston by bolts; the other end of the electric push rod is installed inside the connecting base by bolts.
[0004] In order to solve the problem that the existing structure cannot be produced by the three-layer co-extrusion method, the existing technology adopts the method of designing an extrusion interface. However, the product cannot be cooled and protected in time. The structure does not have a structure to cool the product. If the room temperature is high, the output product cannot be cooled in time, and the product is very likely to be deformed during the movement, which in turn leads to the problem that the quality of the product is easily affected.

However, one or more embodiments can also be implemented by those skilled in the art without these specific details.
[0027] like Figure 1-Figure 5 As shown, a stable eccentric three-layer cable co-extrusion device includes a workbench 1 and a co-extrusion device body 11. The co-extrusion device body 11 is arranged on the top of the workbench 1. The top of the co-extrusion device body 11 is fixedly connected to a feed bin 12. The output end of the co-extrusion device body 11 is detachably connected to a three-layer co-extrusion die head 13. The top of the workbench 1 is provided with a product cooling mechanism 2. The top of the workbench 1 is provided with a heat treatment mechanism 3. The product cooling mechanism 2 includes a support leg 21. The support leg 21 is fixedly installed on the top of the workbench 1. A hollow cylinder 22 is fixedly installed on the top of the support leg 21. A ring network 23 is fixedly installed on the inner wall of the hollow cylinder 22. The front of the hollow cylinder 22 is fixedly connected to a cooling fan 2. 4. The front of the cooling fan 24 is fixedly connected to a connecting air pipe 25, and the end of the connecting air pipe 25 away from the cooling fan 24 is fixedly connected to a hollow bin 26. The hollow bin 26 is fixedly installed on the top of the workbench 1. A thermoelectric cooling plate 261 is fixedly installed on the inner wall of the hollow bin 26, and a hollow plate 264 is fixedly installed on the back of the hollow bin 26. The cooling fan 24 is controlled to draw in external air through the connecting air pipe 25 and the inner cavity of the hollow bin 26, and at the same time, the thermoelectric cooling plate 261 is controlled to work to cool the flowing air in the inner cavity of the hollow bin 26. The low-temperature air is then evenly output from the ring network 23, and the extruded products passing through its inner cavity are cooled in time, thereby improving the quality of the extruded products.
[0028] In this embodiment, a strip-shaped uniform air mesh 265 is fixedly installed on the front side of the inner wall of the hollow plate 264, a cooling fan 266 is fixedly connected to the back side of the hollow plate 264, and an air intake duct 262 is fixedly connected to the bottom of the hollow bin 26. A polyester fiber filter cartridge 263 is threadedly connected to the end of the air intake duct 262 away from the hollow bin 26. The outside air will pass through the polyester fiber filter cartridge 263 and the air intake duct 262 into the inner cavity of the hollow bin 26. The design of the polyester fiber filter cartridge 263 can filter the outside air. The connection relationship design between the air intake duct 262 and the polyester fiber filter cartridge 263 makes it easy for the user to disassemble and clean the polyester fiber filter cartridge 263, and control the cooling fan 266 to work, so as to transport air into the inner cavity of the hollow plate 264. The air then passes through the strip-shaped uniform air mesh 265 and is output to the thermoelectric cooling plate 261, dissipating heat to the hot end of the thermoelectric cooling plate 261, thereby ensuring the cooling effect of the thermoelectric cooling plate 261.
[0029] In this embodiment, the heat treatment mechanism 3 includes a raised platform 31, which is fixedly mounted on the top of the workbench 1, and a square frame 32 is fixedly mounted on the top of the raised platform 31. An inner support seat 38 is fixedly mounted on the inner wall of the square frame 32. The inner wall of the inner support seat 38 is fixedly connected to the outer wall of the co-extrusion equipment body 11. A guide strip 33 is fixedly mounted on the back of the inner wall of the square frame 32. An air inlet 36 is provided on the back of the square frame 32 above the guide strip 33, and an exhaust hole 37 is provided on the back of the square frame 32 below the guide strip 33. The back of the square frame 32 is fixedly connected to The hollow strip 34 is located on the back of the air inlet 36, and the top of the hollow strip 34 is fixedly connected to a hot air blower 35. The hot air blower 35 is controlled to absorb external air and heat it. The hot air is then transported into the hollow strip 34, and then passes through the air inlet 36 into the inner cavity of the square frame 32. The hot air is blocked by the guide strip 33, so that the hot air flows around the outer surface of the co-extrusion equipment body 11, and then is discharged from the exhaust hole 37, thereby realizing the function of auxiliary heating of the co-extrusion equipment body 11, and avoiding the problem of the material easily cooling and solidifying in the inner cavity of the co-extrusion equipment body 11.
[0030] The working principle of the three-layer cable co-extrusion equipment with stable core eccentricity of the present invention is: when in use, the raw materials are added to the inner cavity of the feed bin 12, and then the co-extrusion equipment body 11 is controlled to work, and the raw materials can be heated and output. The raw materials will enter the three-layer co-extrusion die head 13 from the output end of the co-extrusion equipment body 11, and then be output in a three-layer structure from the left end of the three-layer co-extrusion die head 13. During the product output process, the cooling fan 24 is controlled to work, and the outside air is extracted through the inner cavity of the connecting air pipe 25 and the hollow bin 26. At the same time, the thermoelectric cooling plate 261 is controlled to work to cool the flowing air in the inner cavity of the hollow bin 26. The low-temperature air is then evenly output from the ring network 23, thereby realizing the function of timely cooling the extruded product.
