Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production equipment technology, and in particular to a cable sheath extrusion equipment. Background Technology
[0002] A cable is a combination of conductors used to transmit electrical energy or signals, typically consisting of a conductor, insulation layer, shielding layer, and sheath. The cable sheath is the outermost protective structure of the cable, its main function being to prevent mechanical damage, chemical corrosion, moisture intrusion, and environmental factors, while also enhancing the cable's durability and safety. In the cable production process, extrusion equipment is used to heat and melt the sheath material, then extrude it evenly through an extruder head to coat the cable surface, and finally cool and solidify it to form the protective layer.
[0003] Existing cable sheath extrusion equipment subjectes the sheath material to high-temperature heating during the extrusion process, causing thermal decomposition in its molten state and releasing a certain amount of volatile organic compounds (VOCs) and other harmful gases. These gases not only escape into the air from the extrusion outlet along with the formed sheath but also continue to be released during cable cooling. This poses a potential health hazard to operators and pollutes the environment. Utility model patent CN218730142U discloses an environmentally friendly cable extruder. This extruder mainly includes a fixed plate, a fixed pipe connected to the right side of the cable conduit box, and a filter cylinder installed at the right end of the fixed pipe. When the internal gas passes through the filter cylinder, harmful gases are filtered out, preventing any impact on the health of surrounding workers. A fan is installed at the top of the cable conduit box, and the right end of the fan is connected to the top of the filter cylinder via a connecting pipe. Starting the fan extracts the gas from inside the cable conduit box.
[0004] While the cable extruder described in the aforementioned utility patent can extract gas from the cable conduit box and filter harmful gases through a filter cartridge to avoid impacting the health of surrounding workers, the cable conduit box cannot cool the cable. After passing through the conduit box, the cable still maintains a relatively high temperature and therefore releases a certain amount of volatile organic compounds, posing a potential health hazard to operators.
[0005] Therefore, it is necessary to develop a cable sheath extrusion device to address the aforementioned shortcomings. Utility Model Content

[0024] The core of this utility model is to provide a cable sheath extrusion device that rapidly cools the cable sheath during the extrusion process, reducing the release of volatile organic compounds and other harmful gases at high temperatures, and collecting and treating the harmful gases, thereby reducing the harm to the health of operators and the pollution to the environment, and improving the cooling efficiency of the cable.
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In one specific implementation, such as Figure 1 and Figure 2 As shown, a cable sheath extrusion device includes an extruder body 1. A support plate 2 is provided at the discharge end of the extruder body 1. Support columns 3 are fixedly connected to the four corners of the bottom surface of the support plate 2. A cooling box 4 is placed on the top surface of the support plate 2. The inner cavity of the cooling box 4 is connected to the discharge end of the extruder body 1. A discharge port 14 for cable sheath 13 is opened on the side wall of the cooling box 4 away from the extruder body 1. An air-cooling component 5 is provided at the discharge end of the cooling box 4 near the extruder body 1, and a water-cooling component 6 is provided in the middle of the cooling box 4. A ventilation opening is opened on the top surface of the cooling box 4 away from the air-cooling component 5, and a first row of fans 7 is fixedly connected to the ventilation opening. A purification box 8 is fixedly connected to the top surface of the cooling box 4. The first row of fans 7 is located at one end of the inner cavity of the purification box 8, and a purification component is provided at the other end of the inner cavity of the purification box 8.
[0028] In one specific implementation, such as Figure 1 and Figure 2 As shown, the purification component includes a filter screen 9 and an activated carbon adsorption plate 10. The filter screen 9 is vertically arranged on the side close to the first row fan 7, and the activated carbon adsorption plate 10 is vertically arranged on the side away from the first row fan 7.
[0029] The filter screen 9 filters out particulate matter and impurities from the gas entering the purification chamber 8, while the activated carbon adsorption plate 10 adsorbs harmful gases and odors, ensuring that the exhaust air is clean and environmentally friendly.
[0030] Specifically, a purification box door 11 is hinged to one side wall of the purification box 8, and a second row of fans 12 is fixedly installed on the top surface of the purification box 8 away from the first row of fans 7, and the second row of fans 12 is connected to the purification box 8.
[0031] The purification chamber door 11 facilitates the maintenance and replacement of the filter screen 9 and activated carbon adsorption plate 10. At the same time, the second-row fan 12 enhances air circulation, improves purification efficiency, and ensures that hot air is discharged in a timely manner.
[0032] In one specific implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the air-cooled assembly 5 includes an air-cooled plate 501, a fan 502, and several nozzles 503. The air-cooled plate 501 is fixedly connected to the inner wall of the cooling box 4 near the extruder body 1, and the air-cooled plate 501 is hollow inside. The fan 502 is fixedly installed on the outer wall of the cooling box 4, and the air outlet of the fan 502 is connected to the inner cavity of the air-cooled plate 501. Several nozzles 503 are evenly spaced and fixed and connected to the side wall of the air-cooled plate 501 away from the extruder body 1.
[0033] Cool air is delivered to the air-cooling plate 501 by the fan 502. The air-cooling plate 501 distributes the cool air and sprays it evenly onto the surface of the cable sheath 13 through the nozzle 503 to achieve rapid cooling.
[0034] Specifically, several nozzles 503 are arranged parallel to each other and all facing the discharge port 14.
[0035] By setting the nozzles 503 parallel to each other and facing the discharge port 14, it is ensured that the cold air evenly covers the surface of the cable sheath 13, avoiding uneven cooling, and at the same time, the cold air flows along the moving direction of the cable sheath 13, improving the cooling efficiency.
[0036] In one specific implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the water-cooled assembly 6 includes a water pump 601, a water tank 602, and two spray plates 603. The water tank 602 is fixedly connected to the bottom surface of the support plate 2. The water pump 601 is fixedly installed on the outer wall of the water tank 602, and the water inlet of the water pump 601 is connected to the bottom of the water tank 602. The two spray plates 603 are hollow inside and symmetrically arranged on both sides of the cable sheath 13. Spray holes 604 are opened on the opposite sides of the two spray plates 603. The water outlet of the water pump 601 is connected to the inner cavity of the two spray plates 603.
[0037] The water pump 601 delivers the cooling water in the water tank 602 to the spray plate 603, and the spray plate 603 sprays the cooling water evenly onto the surface of the cable sheath 13 through the spray holes 604 to achieve efficient cooling.
[0038] Specifically, the bottom plate of the cooling box 4 is fixed and connected to a conduit 605, which passes through the support plate 2 and the top plate of the water tank 602.
[0039] The cooling water in the cooling tank 4 is returned to the water tank 602 through the conduit 605, realizing the recycling of cooling water. At the same time, the conduit 605 and the water tank 602 are stably connected through the support plate 2 to avoid leakage or blockage.
[0040] Specifically, the two water spray plates 603 have an arc-shaped structure and the bending direction is towards the cable sheath 13.
[0041] The arc-shaped structure of the water spray plate 603 makes it fit more closely to the surface of the cable sheath 13, increasing the coverage of cooling water. At the same time, the bending direction towards the cable sheath 13 ensures that the cooling water is concentrated on the surface of the cable sheath 13, reducing waste and improving cooling efficiency.
[0042] In use, the cable sheath extrusion equipment of this utility model extrudes molten cable sheath material into shape through the extruder body 1. The extruded cable sheath 13 enters the cooling box 4 for cooling and shaping. The cooling process is divided into two stages: air cooling and water cooling. In the air cooling stage, the air cooling component 5 delivers cold air to the air cooling plate 501 through the fan 502. The air cooling plate 501 sprays cold air onto the surface of the cable sheath 13 through evenly distributed nozzles 503, achieving initial cooling. In the water cooling stage, the water cooling component 6 delivers cooling water from the water tank 602 to the spray plate 603 through the water pump 601. The spray plate 603 sprays cooling water evenly onto the surface of the cable sheath 13 through the spray holes 604, further cooling it. By rapidly cooling the cable sheath 13 in the cooling box 4, the release of volatile organic compounds and other harmful gases at high temperatures is reduced. Meanwhile, the hot air generated during the cooling process enters the purification chamber 8 through the ventilation port at the top of the cooling chamber 4. After being filtered by the filter screen 9 to remove particulate matter and impurities, it then passes through the activated carbon adsorption plate 10 to adsorb harmful gases and odors. Finally, the purified air is discharged by the second exhaust fan 12, ensuring that there is no environmental pollution during the production process.
