Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable cooling device for a cable extruder. Background Technology

[0002] A wire extruder is a piece of equipment used to produce various plastic products. It heats and melts plastic raw materials under high temperature and high pressure, and then extrudes them through the die in the extruder head to form the desired shape.

[0003] Existing cable cooling devices typically consist of a water tank filled with cooling water. The cable is cooled by passing through the water in the tank before being inspected and wound up. However, to maintain the cooling effect, the water tanks on the production line are quite long, wasting valuable factory space. For example, CN 222290971U discloses a cable production cooling water tank in which the conductor wheel group guides the cable in a ring within the annular tank, reducing the length of the tank while ensuring the cooling effect on the cable. This effectively improves the production quality and efficiency of cables under limited space conditions. However, when connecting the conductors, unless the cable diameter perfectly matches the size and shape of the lead groove in the conductor wheel group, the contact area between the lead groove and the cable is small when the cable diameter is larger or smaller than the diameter of the lead groove in the conductor wheel group. In this case, because the cable is not sufficiently cooled, the pressure of the lead wheel connecting the conductor can easily cause cable deformation or leave indentations on the cable surface, affecting the production quality of the cable. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable cooling device for a cable extruder. By setting a guide wheel in the water tank, the cable can be guided to change direction and be transported for cooling in the water tank. This allows the cable to be immersed and cooled for a sufficient time in a shorter water tank. While maintaining the cooling effect of the cable, the length of the water tank is reduced, and the space occupied by the water tank in the factory is reduced, thus solving the problems mentioned in the background technology.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a cable cooling device for a cable extruder, comprising a water tank and guide wheels for supporting and guiding cables. The guide wheels are installed inside the water tank via several connecting rods. Two lead wheels are installed inside the water tank via support columns. The lead wheels are located diagonally away from the drainage tank inside the water tank. A flexible connecting part is fixedly connected to the outer wall of the lead wheel. The flexible connecting part includes a flexible support ring and an elastic pad. The flexible connecting part is fixedly connected to the outer wall of the lead wheel, and the elastic pad is fixedly connected to the inner side of the flexible support ring.

[0007] Furthermore, a pulley is fixedly connected to the top of the lead wheel, and the pulleys on the two lead wheels are connected by a drive belt.

[0008] Furthermore, a fixed bracket is fixedly connected to the outer side of the support column, and a support block is fixedly connected to both ends of the fixed bracket near the lead wheel. The support block extends to the inner side of the flexible support ring, and rollers are installed on the upper and lower surfaces of the support block. The rollers abut against the inner wall of the flexible support ring.

[0009] Furthermore, the lead end and outlet end of the two lead wheels connected to the cable are aligned with the drainage trough, and the cable is parallel to the inner wall of the trough when the lead wheels are connected to the cable.

[0010] Furthermore, the elastic pad structure is an arc-shaped pad that bends towards the axis of the lead wheel.

[0011] The beneficial effects of this utility model are as follows:

[0012] The guide rollers guide the cable in a different direction within the water tank for cooling, allowing the cable to be immersed in the tank for a sufficient amount of time. This maintains the cooling effect while reducing the length of the tank and its footprint in the factory. Furthermore, the flexible support rings and elastic pads on the guide rollers deform to conform to the cable surface when in contact with it, increasing the contact area and reducing cable deformation or indentations caused by a small contact area. Simultaneously, the winding mechanism's traction causes the two pulleys to rotate synchronously, allowing both guide rollers to rotate simultaneously and actively guide the cable. This reduces the pulling force exerted on the cable by the guide rollers when connected, maintaining cable production quality. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-3 A cable cooling device for a cable extruder includes a water tank 1 and guide wheels 2 for supporting and guiding the cable. The guide wheels 2 are installed inside the water tank 1 via several connecting rods. Two lead wheels 4 are installed inside the water tank 1 via support columns 3. The lead wheels 4 are located diagonally inside the water tank 1 away from the drainage tank 5. A flexible connecting part is fixedly connected to the outer wall of the lead wheel 4. The flexible connecting part includes a flexible support ring 6 and an elastic pad 7. The flexible connecting part is fixedly connected to the outer wall of the lead wheel 4, and the elastic pad 7 is fixedly connected to the inner side of the flexible support ring 6.

[0019] In this solution: the guide wheel 4 guides the cable in the water tank 1 to change direction for cooling, allowing the cable to be immersed and cooled for a sufficient time in the shorter water tank 1. While maintaining the cooling effect of the cable, the length of the water tank 1 is reduced, thus reducing the space occupied by the water tank 1 in the factory. Furthermore, the flexible support ring 6 and elastic pad 7 set on the guide wheel 4 allow the elastic pad 7 to deform and fit against the cable surface when it comes into contact with the cable. At the same time as the elastic pad 7 deforms, it can pull the flexible support ring 6 to deform in the direction of the elastic pad 7, increasing the contact area between the elastic pad 7 and the cable. When guiding cables whose diameter does not perfectly match the guide groove of the guide wheel 4, the contact can be changed from point contact to surface contact, thus making it suitable for cables of different sizes. This reduces the cable deformation or indentation on the cable surface caused by the small contact area of ​​the guide wheel 4, maintaining the flatness of the cable surface.

[0020] A pulley 8 is fixedly connected to the top of the lead wheel 4, and the pulleys 8 on the two lead wheels 4 are connected by a transmission belt 9.

[0021] In this embodiment: by setting pulley 8 and drive belt 9, under the traction force during cable winding, the two lead pulleys 4 can rotate synchronously under the drive of pulley 8 and drive belt 9, making the traction force during cable transportation more stable, reducing the pulling force of lead pulley 4 on cable, and making the traction force of lead pulley 4 on cable more uniform. When the cable passes through the first lead pulley 4 to guide the direction, it prevents the cable from being damaged due to different traction forces when the two lead pulleys 4 rotate. In addition, it prevents the internal structure of the cable from being affected when the cable bends on the first lead pulley 4 because the cable has not been fully cooled and shaped.

[0022] A fixed bracket 10 is fixedly connected to the outside of the support column 3. Support blocks 11 are fixedly connected to both ends of the fixed bracket 10 near the lead wheel 4. The support blocks 11 extend to the inside of the flexible support ring 6, and rollers 12 are installed on the upper and lower surfaces of the support blocks 11. The rollers 12 abut against the inner wall of the flexible support ring 6.

[0023] In this embodiment: With the fixed bracket 10 and the support block 11, the support block 11 can support the inner side of the flexible support ring 6. As the flexible support ring 6 rotates with the lead wheel 4, the flexible support ring 6 can open outward under the support of the support block 11, preventing the flexible support ring 6 from rubbing against the cable during the cable entry process due to the flexible support ring 6 bending inward and not springing back in time, thereby effectively protecting the cable. At the same time, the roller 12 provided on the support block 11 can reduce the friction between the support block 11 and the flexible support ring 6, thereby protecting the flexible support ring 6 and extending its service life.

[0024] The lead end and outlet end of the two lead wheels 4 are aligned with the drainage trough 5 respectively, and the cable is parallel to the inner wall of the water tank 1 when the lead wheels 4 are connected to the cable.

[0025] In this embodiment: by setting two lead wheels 4 at diagonal positions away from the drainage trough 5, and when the lead wheels 4 are connected to the cable, the cable is parallel to the inner wall of the water tank 1, so that when the cable is transported in the water tank 1 and wound onto the lead wheels 4, the cable can first maintain a straight state and cool down in the water tank 1 for a certain period of time, so that the surface of the cable can be cooled and hardened, thereby greatly reducing the impact on the internal structure of the cable when it bends before it is fully cooled. After the cable is guided and turned by the first lead wheel 4 and moves to the second lead wheel 4, the cable can again maintain a straight state and cool down. At this time, the overall temperature of the cable will decrease again, and the strength of the cable after hardening will increase again, so that the impact of the second lead wheel 4 on the internal structure of the cable will be reduced again. Finally, the temperature of the cable led out by the second lead wheel 4 can be reduced to within the standard range after it is led out, so that the cable can be fully cooled in a shorter water tank 1, reducing the area occupied by the water tank 1 in the factory.

[0026] The elastic pad 7 is an arc-shaped pad that bends toward the axis of the lead wheel 4.

[0027] In this embodiment, the elastic pad 7, which bends toward the axis of the lead wheel 4, can deform with the diameter of the cable and fit against the surface of the cable when it comes into contact with the cable, increasing the contact area with the cable. This makes the traction force on the cable more uniform when the lead wheel 4 rotates, thereby protecting the cable and preventing deformation or indentation caused by insufficient contact area with the lead wheel 4.

[0028] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
