[0002] As we all know, wires and cables are usually used to transmit electrical energy. They can also be used as wire products for information and electromagnetic energy conversion. When cables are in use, they are usually protected by insulating sheaths. Insulating sheaths usually need to be produced, and then extrusion molding devices will be used.

[0003] After high-temperature extrusion, the cable sheath is still in a hot state and may not be completely stable. At this time, if the temperature is not cooled in time, the sheath may be deformed or cracked due to internal stress or external factors. Traditional cooling devices are insufficient in cooling efficiency. Due to design or technical limitations, heat cannot be removed quickly and effectively, resulting in a slow drop in the temperature of the sheath during the cooling process, and even uneven temperature may occur, which affects the quality and performance of the sheath, and has poor environmental performance.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4, an extrusion device for wire and cable sheath processing, comprising an extrusion body 1, a cooling device and a dehumidification device, a hopper 2 is installed at the top of the extrusion body 1, a conveying motor 3 is installed at one end of the extrusion body 1, an extrusion tube 4 is installed at the other end of the extrusion body 1, a wire installation frame 5 is installed at the top of the extrusion tube 4, the cooling device comprises a cooling box 6, a water pipe 7, an annular pipe 8, an atomizing nozzle 9 and a pump body 10, the cooling box 6 is installed at one end of the extrusion body 1 close to the extrusion tube 4, a cooling cavity 11 is opened on the upper part of the cooling box 6, and through-holes are opened at the left and right ends of the cooling box 6 respectively. The cooling cavity 11 has a feed hole 12 and a discharge hole 13, a water storage tank 14 is installed at the lower part of the cooling box 6, a plurality of water pipes 7 are installed on one side of the top of the water storage tank 14, the annular tube 8 is installed at the output end of the water pipe 7, a plurality of atomizing nozzles 9 are arranged in a ring shape on the inner circle of the annular tube 8, the pump body 10 is installed on the water pipe 7, a drain trough 15 is provided at the top of the water storage tank 14, a fixing seat 16 is installed at one end of the cooling box 6 away from the feed hole 12, a dehumidification device is installed at one end of the top wall of the fixing seat 16 close to the discharge hole 13, and another end of the fixing seat 16 is provided. A winding machine 17 is installed at one end. In this embodiment, when in use, first, the plastic is fed into the extrusion body 1 through the hopper 2. Under the action of the conveying motor 3, the plastic is extruded, melted and plasticized in the extrusion body 1. Subsequently, the molten plastic passes through the extrusion tube 4 and is extruded on the wire core or cable under the guidance of the wire installation frame 5 to form a cable sheath. After the cable sheath is extruded from the extrusion tube 4, it first enters the feed hole 12 of the cooling box 6. In the cooling box 6, the cable sheath contacts the relatively low ambient temperature and starts the initial cooling process. The cable sheath enters the cooling cavity 11 and passes through the multiple groups of annular tubes 8. At the same time, the water storage tank 1 The cooling water in 4 is transported to multiple groups of water pipes 7 through the pump body 10, and then reaches the atomizing nozzle 9 through the annular pipe 8. The atomizing nozzle 9 atomizes the cooling water into fine water droplets. These water droplets contact with the high-temperature cable sheath around in the cooling cavity 11, absorb a large amount of heat by evaporation, thereby achieving rapid cooling. The water sprayed by the atomizing nozzle 9 enters the water tank 14 through the drain trough 15, and then the cooling water is recycled. Finally, the cable sheath after cooling is output at the discharge hole 13, and then the cable sheath enters the dehumidification device to remove the moisture on the surface of the cable sheath to ensure that it is dry, and finally it is wound up by the winder 17.

[0026] In actual use, it is further convenient to dehumidify the cable sheath after cooling. In this embodiment, the dehumidification device includes a bidirectional screw 18, a slider 19, a movable frame 20, a cotton roller 21 and a drive shaft 22. The fixed seat 16 is provided with a rectangular groove at one end away from the winding machine 17, and the bidirectional screw 18 is installed in the rectangular groove. One end of the bidirectional screw 18 passes through the side wall of the fixed seat 16 and the drive shaft 22 is installed. The slider 19 is installed at both ends of the bidirectional screw 18, and the movable frame 20 is installed at the top of the slider 19. Multiple groups of cotton rollers 21 are rotatably installed on the movable frame 20. When the cable sheath cooled by the cooling device is output through the discharge hole 13, it will roll through the multiple groups of cotton rollers 21 between the two groups of movable frames 20. During the rolling process, the cotton rollers 21 will The wall generates a certain pressure, and this mechanical extrusion effect can further remove the residual moisture or water inside the cable sheath. Through the continuous rolling of the cotton roller 21, the cable sheath is constantly squeezed and released during the movement, thereby accelerating the discharge of moisture. The material of the cotton roller 21 usually has good hygroscopicity. The cotton roller 21 can absorb moisture or water droplets on the outer wall of the cable sheath. This physical adsorption effect can effectively remove moisture from the surface of the cable sheath, thereby achieving the effect of dehumidification. When it is necessary to adjust the tension between the cotton roller 21 and the cable sheath, manually rotate the drive shaft 22 to drive the bidirectional screw 18 to rotate. During the rotation, the bidirectional screw 18 drives the slider 19 to move linearly in the rectangular groove, and the slider 19 drives the moving frame 20 to move toward the middle at both ends until the cotton roller 21 is adjusted to the required tension, thereby improving the flexibility of the use of the cotton roller 21.

[0027] In actual use, in order to further facilitate driving the driving shaft 22 , in this embodiment, a turntable 23 is installed on the driving shaft 22 , and the design of the turntable 23 facilitates further driving the rotation of the driving shaft 22 .

[0028] In actual use, the anti-slip property of the drive shaft 22 is further improved. In this embodiment, the turntable 23 is provided with anti-slip grooves. The design of the anti-slip grooves can increase the contact area between the turntable 23 and the drive shaft 22, thereby increasing the friction between them. This increased friction can ensure that the drive shaft 22 is more stable when rotating and reduce the possibility of sliding or skidding.

[0029] In actual use, it is further convenient to filter the water. In this embodiment, a filter plate 24 is installed in the water storage tank 14. The filter plate 24 can effectively remove impurities and particulate matter in the water, thereby significantly improving the water quality and preventing the recycled water from clogging the atomizing nozzle 9.

[0030] In actual use, it is further convenient to recycle the sprayed water. In the present embodiment, the drain trough 15 is designed to be low in the middle and high at both ends. Due to the design of being low in the middle and high at both ends, when water is sprayed, due to the effect of gravity, the water will naturally flow to the lower part of the drain trough 15, that is, the middle position. Such a design ensures a clear direction of the water flow, so that the water can flow into the drain trough 15 more concentratedly, and then enter the water storage tank 14 in time, reducing the diffusion and waste of the water flow.

[0031] In actual use, it is further convenient to inspect and repair the cooling device. In this embodiment, an inspection door 25 is installed on the front end face of the cooling box 6. The inspection door 25 is made of transparent material. The inspection door 25 provides a channel for direct access to the interior of the cooling box 6, so that the staff can easily enter the cooling box 6 to perform inspections, repairs or replacement of parts. The transparent material allows the staff to preliminarily observe and judge the situation inside the cooling box 6, such as the operating status of the equipment, whether there are any abnormalities or faults, etc., without opening the inspection door 25.

[0032] In actual use, it is further convenient to support the annular pipe 8. In the present embodiment, a support frame 26 for supporting the annular pipe 8 is installed at one end of the top of the water storage tank 14 away from the water pipe 7. The support frame 26 can effectively support the annular pipe 8 to prevent it from sagging or deforming due to gravity or external force, thereby ensuring the stability of the entire water supply system. The support frame 26 can share the force and stress exerted on the annular pipe 8, reduce the force concentration on the annular pipe 8, thereby reducing the stress and fatigue of the annular pipe 8, and helping to extend the service life of the annular pipe 8.
