Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable processing, and particularly to an automated processing device and processing technology for wire and cable production and manufacturing. Background Art

[0002] The production and manufacturing of wire and cable refers to the entire process of processing conductors, insulating materials, and other components into wires and cables. This process usually includes multiple processes such as stranding of conductor cores, extrusion of insulation layers, and extrusion of outer sheaths. Among them, an automated extrusion device for wire and cable production and manufacturing is used. Traditional extrusion devices mostly adopt a process of extrusion in stages. After extruding the first layer on the outer wall of the conductor core, it is necessary to wait for the surface of the first layer to completely cool and form before extruding the next layer. This may cause the following problems in the actual production process:

[0003] 1. After each layer of coating of the wire and cable, it is necessary to wait for complete cooling, resulting in an extended production cycle and greatly reducing the overall production efficiency.

[0004] 2. During the cooling process after each layer of coating of the wire and cable, it may be contaminated with dust and impurities, which will cause poor bonding between the first layer and the second layer, affecting the insulation performance and overall strength.

[0005] 3. The staged process results in a very long extrusion production line, requiring more production space to place equipment and cooling areas, increasing the cost of factory building construction and operation.

[0006] 4. It is difficult to precisely control the cooling rate of each layer. If the cooling time of the coating is too long, it may cause changes in its surface state, affecting the bonding strength with the next coating.

[0007] 5. Excessive cooling may cause the material to shrink and deform concentratedly, resulting in stress concentration inside the coating and increasing the risk of fracture or damage of the cable during use.

[0008] Therefore, it is very necessary to invent an automated processing device and processing technology for wire and cable production and manufacturing. Summary of the Invention

Immediately afterwards, the first wrapping material in the first feeding conduit 22 is extruded into the first extrusion groove 18 and wrapped on the outer wall of the wire core 17. At the same time, the second wrapping material in the second feeding conduit 23 is extruded into the second extrusion groove 19, and the third wrapping material in the third feeding conduit 24 is extruded into the third extrusion groove 20; Then start the condenser to circulate the coolant in the first cooling conduit 27, the second cooling conduit 28 and the third cooling conduit 29, and at the same time start the water heater to circulate the hot water in the first heating conduit 30 and the second heating conduit 31. The first cooling conduit 27 cools the first wrapping material in the first extrusion groove 18 and solidifies on the surface of the wire core 17 to form the first cladding layer; The second cooling conduit 28 cools the outside of the second wrapping material in the second feeding conduit 23 to reduce its overall temperature and solidify on the surface. At the same time, the first heating conduit 30 softens the inside of the second wrapping material in the second feeding conduit 23 to maintain its fluidity and adhesiveness; On the other hand, the third cooling conduit 29 cools the outside of the third wrapping material in the third feeding conduit 24 to reduce its overall temperature and solidify on the surface. At the same time, the second heating conduit 31 softens the inside of the third wrapping material in the third cooling conduit 29 to make its surface solidify; After the first cladding layer is completely solidified, the second wrapping material is extruded and coated on the surface of the first cladding layer to form the second cladding layer. Immediately afterwards, the third wrapping material is extruded and coated on the surface of the second cladding layer to form the third cladding layer; After the first cladding layer, the second cladding layer and the third cladding layer are completely coated on the surface of the wire core 17, as the wire core 17 enters the water cooling chamber 32, start the pressure spray head 35 to pump water from the water tank 36 through the spray conduit 34 and spray it out to further cool the wire core 17 and the first cladding layer, the second cladding layer and the third cladding layer on its surface; The wire core 17 with the surface cladding layer completely cooled and formed passes out of the water cooling chamber 32, bypasses the top slot of the take-up wheel disc 16 and is wound on the surface of the take-up roller 14. After the extrusion of the wire core 17 is completed, finally the staff removes the take-up roller 14 on the loading turntable 15, affixes a label and packs it into the warehouse.
