Description

Technical Field

[0001] This application relates to the field of cable technology, specifically to a device for coating color stripes on the surface of flexible cables. Background Technology

[0002] Most signal transmission cables and control cables commonly found on the market are multi-core cables. These cables are generally made up of multiple insulated cores (i.e. wires) twisted together. To facilitate their subsequent use, manufacturers use various colors to distinguish the wires during the cable manufacturing process. The cable surface color stripe coating device is a device that coats the cable surface with color stripes.

[0003] Currently, during the coating process, a wire feeding spool is used to feed the cable, while a take-up spool acts as a pulling force to wind the cable. However, tension issues can easily arise during the pulling process, causing the cable to rotate and resulting in the deviation of the coating stripe. Utility Model Content

[0004] The purpose of this application is to provide a flexible cable surface color stripe coating device, which solves the problem mentioned in the background art that when the cable is coated, the cable is released by the release drum and the cable is wound up by the take-up drum. However, the cable is prone to tension problems during the pulling process, which leads to the cable rotating and causing the color stripe on the cable to shift.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a flexible cable surface color stripe coating device, including a vertical plate. Three sets of pulleys are rotatably installed on the inner wall of the vertical plate. Each set of pulleys is divided into upper and lower pulleys. An installation plate is fixedly installed on the outer wall of the vertical plate above the two pulleys. A hydraulic rod is fixedly installed at the lower end of the installation plate. A U-shaped frame is fixedly installed at the telescopic end of the hydraulic rod. A tension adjustment wheel is rotatably installed on the inner wall of the U-shaped frame. A spring is sleeved on the outer wall of the hydraulic rod. The two ends of the spring are fixedly installed to the installation plate and the U-shaped frame, respectively. A spraying mechanism is provided on one side of the vertical plate between the other two pulleys.

[0007] By adopting the above technical solution, and by setting three sets of pulleys on the vertical plate, the tension adjustment wheel can be driven by hydraulic rods and springs. The tension can be adjusted in real time according to the cable tension, avoiding the cable from rotating due to uneven tension and effectively preventing the color strip from shifting. This device solves the problem of rotation and color strip shift caused by unstable cable tension in the traditional coating process, improves coating accuracy and product quality, and is especially suitable for surface color strip coating processing of multi-core cables.

[0008] Optionally, a positioning plate is fixedly installed on the side of the vertical plate away from the pulley.

[0009] By adopting the above technical solution, the vertical plate can be used to fix the positioning plate.

[0010] Optionally, the upper side of the positioning plate is provided with two sets of positioning holes.

[0011] By adopting the above technical solution, the positioning holes facilitate the installation of the positioning plate with the help of bolts from external equipment.

[0012] Optionally, the spraying mechanism includes a mounting bracket fixedly installed on the outer wall of the vertical plate, the mounting bracket being T-shaped.

[0013] By adopting the above technical solution, the vertical plate can be used to fix the mounting bracket.

[0014] Optionally, a mounting ring is fixedly installed on the side of the mounting bracket away from the vertical plate, and a mounting hole is provided in the inner wall above the mounting ring.

[0015] By adopting the above technical solution, the mounting bracket can be used to fix the mounting ring.

[0016] Optionally, a nozzle is fixedly mounted on the inner wall of the mounting ring located inside the mounting hole, and a connecting pipe is mounted on the upper end of the nozzle, the connecting pipe extending to the outside of the mounting ring.

[0017] By adopting the above technical solution, the mounting hole can be used to house and install the connecting pipe and the nozzle, while the mounting ring can fix the nozzle and the connecting pipe, and the connecting pipe can be connected to the liquid injection pipeline.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application sets three sets of pulleys on the vertical plate and uses hydraulic rods and springs to drive the tension adjustment wheel. It can adjust the tension in real time according to the cable tension, avoid the cable from rotating due to uneven tension, and effectively prevent the color strip from shifting. This device solves the problem of rotation and color strip shift caused by unstable cable tension in the traditional coating process, improves coating accuracy and product quality, and is especially suitable for surface color strip coating processing of multi-core cables.

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.

[0027] Please see Figure 1-4 This application provides a technical solution: a flexible cable surface color stripe coating device, including a vertical plate 1, three sets of pulleys 2 are rotatably installed on the inner wall of the vertical plate 1, each set of pulleys 2 is divided into upper and lower pulleys 2, an installation plate 3 is fixedly installed on the outer wall of the vertical plate 1 above the two pulleys 2, a hydraulic rod 4 is fixedly installed at the lower end of the installation plate 3, a U-shaped frame 6 is fixedly installed at the telescopic end of the hydraulic rod 4, a tension adjustment wheel 7 is rotatably installed on the inner wall of the U-shaped frame 6, a spring 5 is sleeved on the outer wall of the hydraulic rod 4, and the two ends of the spring 5 are fixedly installed to the installation plate 3 and the U-shaped frame 6 respectively, and a spraying mechanism is provided on one side of the vertical plate 1 between the other two pulleys 2;

[0028] In the technical solution of this application, by setting three sets of pulleys 2 on the vertical plate 1, and using the hydraulic rod 4 and spring 5 to drive the tension adjustment wheel 7, the tension can be adjusted in real time according to the cable tension, avoiding the cable from rotating due to uneven tension, and effectively preventing the color strip from shifting. This device solves the problem of rotation and color strip shift caused by unstable cable tension in the traditional coating process, improves the coating accuracy and product quality, and is especially suitable for surface color strip coating processing of multi-core cables.

[0029] In the technical solution of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the spraying mechanism includes a mounting bracket 8 fixedly installed on the outer wall of the vertical plate 1. The mounting bracket 8 is T-shaped and can be fixed by the vertical plate 1. A mounting ring 9 is fixedly installed on the side of the mounting bracket 8 away from the vertical plate 1. A mounting hole 10 is opened in the inner wall above the mounting ring 9. The mounting bracket 8 can fix the mounting ring 9. A nozzle 11 is fixedly installed on the inner wall of the mounting ring 9 located inside the mounting hole 10. A connecting pipe 12 is installed at the upper end of the nozzle 11.
