Description

Uniform cooling structure based on cable extrusion equipment Technical Field

[0001] This utility model relates to the field of cable processing, and in particular to a uniform cooling structure based on cable extrusion equipment. Background Technology

[0002] Cable extrusion equipment is a type of equipment used to produce wires and cables. It is mainly used to heat and melt plastic raw materials and then extrude them through the die of the extruder head. This equipment usually consists of multiple parts, including a wire feeding frame, a wire infeed frame, a main unit, a cooling water tank, a drying unit, a printing machine, a track traction unit, a take-up and wire laying machine, and a temperature control electrical control cabinet. Wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In the existing technology, after the wires and cables are extruded, they need to be cooled along with the wires and cables. However, the existing cooling methods are to immerse the extruded cables in water for cooling.

[0003] For example, patent number (CN215007727U) discloses a compound silicone rubber wire and cable extrusion equipment, including a bracket and a support base. The support base is installed on one side of the bracket, and a sealing structure is installed on the top of the bracket. A cooling structure is installed on the top of the support frame. The sealing structure includes: a sealing chamber, two heating layers, a first sealing gasket, a feed pipe, a booster pump, a discharge pipe, a second sealing gasket, and an extrusion die. This utility model relates to the technical field of compound silicone rubber wire and cable extrusion equipment. The beneficial effect of this case is that it solves the problem that in the prior art, when the extrusion equipment extrudes the material, the material is easily squeezed inside the material chamber, resulting in uneven extrusion, which causes uneven mixing of the material and the wire core, affecting the quality of cable production.

[0004] Currently, the uniform cooling structure of cable extrusion equipment has certain limitations during operation. Immersion cooling can easily lead to unevenness on the outer surface of the cable, affecting the quality of the cable. At the same time, the cooling water has a low level of pollution and is directly discharged after cooling, which can easily lead to a certain waste of resources. Summary of the Invention

[0005] To overcome the limitations of the uniform cooling structure of cables, which can easily lead to unevenness on the outer surface of the cable and affect the quality of the cable, and the fact that the cooling water has a low degree of pollution and is directly discharged after cooling, which can easily cause a certain waste of resources.

[0006] The technical solution of this utility model is as follows: Based on the uniform cooling structure of cable extrusion equipment, it includes an extrusion processing body, a receiving water tank is fixedly installed on the lower right side of the extrusion processing body, a water cooling box is fixedly installed on the upper end of the receiving water tank, a water outlet pipe is connected to the upper end of the water cooling box, a liquid pump is fixedly installed on the surface of the water outlet pipe, a distribution pipe is fixedly installed inside the water cooling box, an atomizing nozzle is fixedly installed on the surface of the distribution pipe, a drying box is fixedly installed on the upper end of the receiving water tank located on the side of the water cooling box, a water storage tank is fixedly installed at the rear end of the receiving water tank, a filter box is fixedly installed on the upper end of the water storage tank, a circulating water pipe is fixedly installed on the upper end of the filter box, and a liquid pump is provided on the surface of the circulating water pipe.

[0007] Preferably, the cable extrusion equipment works in conjunction with related equipment to extrude and transport the material. One end of the water outlet pipe extends to the bottom of the water storage tank for easy pumping. The filter box contains a filter screen that filters and purifies the cooling water, separating dust and impurities. The filtered water is then collected and stored in the water storage tank. The filter screen is easy to disassemble and remove for regular maintenance to ensure its filtration performance. The guide roller supports and guides the extruded cable. The first liquid pump drives low-temperature clean water from the water outlet pipe into the distribution pipe, which is then sprayed onto the cable surface through atomizing nozzles for rapid water cooling. The fan drives airflow, causing the airflow to blow onto the cable from the air outlet of the connecting pipe groove, further drying the cable. The water receiving tank collects the cooling water that has been sprayed or dripped onto the cable surface. The second liquid pump drives the collected cooling water into the filter box.

[0008] Preferably, an extrusion die is fixedly installed on the right end of the extrusion processing body, a support frame is fixedly installed on the inner side of the water receiving tank, and a guide roller is rotatably connected to the inner side of the support frame.

[0009] Preferably, the upper end of the cooling drying box is provided with a ventilation slot, a fan is fixedly installed inside the ventilation slot, a connecting pipe groove is fixedly installed inside the cooling drying box, and an air outlet is fixedly installed on the inner side of the connecting pipe groove.

[0010] Preferably, the ventilation duct and the connecting pipe duct are connected to each other, a dustproof net is fixedly installed on the upper side inside the ventilation duct, and the air outlets are distributed in a ring array.

[0011] Preferably, the atomizing nozzles are evenly spaced, and the end of the water outlet pipe furthest from the water-cooled box is connected to the water storage tank.

[0012] Preferably, the filter box and the water storage tank are connected to each other, and the end of the circulating water pipe away from the filter box is connected to the receiving water tank.

[0013] Preferably, a water inlet is fixedly installed on the upper side of the water tank, and a water exchange inlet is fixedly installed at the front end of the water tank.

[0014] The beneficial effects of this utility model are:

[0015] This uniform cooling structure based on cable extrusion equipment sprays water mist onto the cable surface through atomizing nozzles, making the distribution more uniform and achieving rapid water cooling. It also avoids the unevenness of the cable's outer surface caused by immersion in water. The fan drives airflow to facilitate the drying of the cable, which helps improve the processing quality of the cable extrusion equipment.

[0016] The cooling water that has been sprayed and dripped onto the cable surface is collected by a water tank. The collected cooling water is then driven by a second liquid pump into a filter box and finally collected and stored in a water storage tank. This allows the first liquid pump to work with the outlet pipe to pump water again, achieving the recycling of low-temperature clean water. This avoids the direct discharge of cooling water, which would otherwise waste water resources. The cooling water has a low level of pollution, is easy to filter, and has low purification costs, which helps to improve the environmental friendliness of the uniform cooling structure of the cable extrusion equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Cable extrusion equipment is a key piece of equipment used in the production of wires and cables. It primarily processes various raw materials into standard-compliant wires and cables through a series of complex and precise processes. Specifically, cable extrusion equipment heats and melts plastic raw materials under high temperature and pressure, then extrudes them through a die in the extruder head. These devices typically consist of a pay-off frame, infeed frame, main unit, cooling water tank, drying unit, printing machine, tracked traction system, take-up and cable-laying machine, and temperature control electrical control cabinet.

[0026] Cable extrusion equipment heats and melts plastic raw materials under high temperature and pressure, then extrudes them through the die in the extruder head. The specific process includes the following steps: Feeding: Raw materials enter the extruder through a feeding device; Heating and Melting: The raw materials are heated to a molten state inside the main unit; Extrusion Molding: The molten plastic is extruded through the die in the extruder head; Cooling and Curing: The extruded plastic is cooled and cured in a cooling water tank; Post-processing: This includes drying, printing, traction, and cable winding. The working principle of cable extrusion equipment is that a screw of a specific shape rotates inside a heated barrel, forcing the plastic forward, causing it to be uniformly plasticized (i.e., melted). Through the die head and dies of different shapes, the plastic is extruded into continuous plastic layers of various shapes, which are then extruded onto the wire core and cable. In the plasticizing stage: The plastic is stirred and extruded by the rotating screw inside the barrel, gradually changing from a granular solid to a plastic viscous fluid. The heat sources in this stage include electric heating outside the barrel and frictional heat generated by the rotating screw. Molding stage: Inside the die head, the viscous fluid is pushed towards the die head and molded into a plastic layer of the required size and shape, covering the wire core or conductor. Shaping stage: The plastic layer passes through a cooling water tank or cooling pipe, changing from an amorphous plastic state to a shaped solid state.

A circulating water pipe 11 is fixedly installed at the upper end of the filter box 10. A liquid pump 12 is installed on the surface of the circulating water pipe 11. The liquid pump 15 drives low-temperature clean water from the outlet pipe 4 into the distribution pipe 6. The water is sprayed onto the surface of the cable through the atomizing nozzle 7 to achieve rapid water cooling. The fan 17 drives the air flow to further dry the cable quickly and prevent it from being immersed in water, which would cause the cable surface to become uneven. At the same time, the water is recycled by the receiving water tank 2 and the filter box 10 and stored back in the water storage tank.

[0028] Please refer to Figures 1-5. In this embodiment, an extrusion die 13 is fixedly installed on the right end of the extrusion processing body 1. A support frame 14 is fixedly installed on the inner side of the receiving water tank 2. A guide roller 15 is rotatably connected to the inner side of the support frame 14.

A connecting pipe slot 18 is fixedly installed inside the cooling drying box 8. An air outlet 19 is fixedly installed on the inner side of the connecting pipe slot 18. The ventilation slot 16 and the connecting pipe slot 18 are interconnected. A dustproof net is fixedly installed on the upper side inside the ventilation slot 16. The air outlets 19 are arranged in a ring array. The extrusion processing body... The main body 1 performs the operation and extrudes the material from the extrusion die 13. It works in conjunction with other related equipment for the cable and is supported and guided by the guide roller 15 to realize the extrusion and transmission of the material, allowing it to pass through the water cooling box 3 and the air drying box 8 in one go. The liquid pump 5 drives low-temperature clean water from the water outlet pipe 4 into the distribution pipe 6, and sprays it onto the cable surface through the atomizing nozzle 7 to achieve rapid water cooling. The fan 17 drives the airflow, so that the airflow blows the cable from the air outlet 19 of the connecting pipe groove 18 to the cable, further drying the cable and achieving rapid cooling of the cable, while avoiding immersion in water and the resulting unevenness on the outer surface of the cable.

[0029] Please refer to Figures 1-4. In this embodiment, the atomizing nozzles 7 are evenly spaced. The end of the water outlet pipe 4 away from the water-cooled box 3 is connected to the water storage tank 9. The filter box 10 is connected to the water storage tank 9. The end of the circulating water pipe 11 away from the filter box 10 is connected to the receiving water tank 2. A water inlet is fixedly installed on the upper side of the water storage tank 9, and a water exchange port is fixedly installed at the front end of the water storage tank 9. The cooling water that has been sprayed and dripped onto the cable surface is collected through the receiving water tank 2. The collected cooling water is driven by the second liquid pump 12 into the filter box 10. The filter screen inside the filter box 10 filters and purifies the water, separating dust and impurities. Finally, the water is collected and stored in the water storage tank 9, which is convenient for the first liquid pump 5 to pump water again with the water outlet pipe 4, realizing the recycling of low-temperature clean water.

[0030] During operation, the extrusion processing body 1 performs the work, extruding material from the extrusion die 13. It works in conjunction with other related cable equipment, and is supported and guided by the guide roller 15 to achieve material extrusion and transmission, allowing it to pass through the water cooling box 3 and the air drying box 8 in one go. The liquid pump 5 drives low-temperature clean water from the outlet pipe 4 into the distribution pipe 6, and sprays it onto the cable surface through the atomizing nozzle 7 to achieve rapid water cooling. The fan 17 drives airflow, causing the airflow to blow onto the cable from the air outlet 19 of the connecting pipe groove 18, further drying the cable and achieving rapid cooling of the cable, while avoiding immersion in water and the resulting unevenness on the cable's outer surface. The cooling water that has been sprayed and dripped onto the cable surface is collected by the receiving water tank 2. The liquid pump 12 drives the collected cooling water into the filter box 10, where it is filtered and purified by the filter screen inside the filter box 10 to separate dust and impurities from the water. Finally, it is collected and stored in the water storage tank 9, which is convenient for the liquid pump 5 to pump water again with the outlet pipe 4, realizing the recycling of low-temperature clean water.

[0031] Through the above steps, the liquid pump 5 drives low-temperature clean water from the outlet pipe 4 into the distribution pipe 6, and sprays it onto the cable surface through the atomizing nozzle 7 to achieve rapid water cooling. In conjunction with the fan 17 driving airflow, the cable is further dried quickly, avoiding the unevenness of the cable's outer surface caused by immersion in water. At the same time, the water is recycled using the receiving tank 2 and the filter box 10 and stored again in the water storage tank 9. This solves the problem that the uniform cooling structure of the cable has certain limitations, which can easily lead to an uneven outer surface of the cable, affecting the quality of the cable. In addition, the cooling water has a low degree of pollution and is directly discharged after cooling, which can easily cause a certain amount of resource waste.
