Description

Technical Field

[0001] This utility model relates to a coating device, and more particularly to a coating device for cable conductor insulation. Background Technology

[0002] As a critical infrastructure, cable insulation is a key component that protects the inner conductor of the cable from external environmental influences. It plays an important role in preventing short circuits and ensuring equipment and personal safety. The quality of its insulation layer directly affects the safety and stability of the entire system.

[0003] During the coating process, a transmission device is used to smoothly transport the cable through the coating area and uniformly cover the cable surface with insulating material, forming a continuous and dense insulating layer on the cable surface. In the traditional coating process, it is difficult to ensure that the insulating layer is evenly distributed on the cable conductor, especially when the conductor surface shape is complex or the conductor diameter varies. The use of insulating material is often difficult to control precisely, which can easily lead to material waste and increased costs. Utility Model Content

Detailed Implementation

[0021] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0022] Example 1: A cable conductor insulation coating device, such as Figure 1-4As shown, the system includes: a base 1, with straightening wheels 3 symmetrically arranged on the upper right side of the base 1. The main function of these straightening wheels 3 is to straighten the bent parts of the cable by squeezing and guiding, adjusting and maintaining the straightness of the cable conductor before entering the coating area, thereby ensuring the uniformity and overall quality of the subsequent coating. A distribution joint 4 is located on the upper right side of the base 1, also with a symmetrical design. Each distribution joint 4 is connected to an inlet pipe 42 at its upper part. These inlet pipes 42 are directly connected to external paint delivery pipes or containers to stably deliver paint into the distribution joint 4. The distribution joint 4 has a unique discharge structure designed to ensure uniform flow of paint from top to bottom within it. Each distribution joint 4 has a telescopic pipe 44 at its lower part. The telescopic pipe 44 is L-shaped and connected to a section of pipe via an elastic element. Each telescopic pipe 44 has a coating plate 45 at its lower part. Both coating plates 45 are arc-shaped and can move back and forth a certain distance on the connected telescopic pipe 44 through contact with the cable. To achieve automatic adjustment of the coating plates 45, both coating plates 45 adopt an arc-shaped design to better fit and coat the surface of the cable conductor. Each coating plate 45 has a through hole communicating with the lower end of the telescopic tube 44. The coating material entering the distribution joint 4 from the feed pipe 42 flows through the telescopic tube 44 and is extruded from the through hole of the coating plate 45. Each distribution joint 4 has an air inlet pipe 43 connected to one end, communicating with the interior of the distribution joint 4. The air inlet pipe 43 is used to connect to external pressure equipment to adjust the pressure inside the distribution joint. The system is designed to adjust the coating extrusion amount. One end of the air inlet pipe 43 extends outward from the base. A bracket 5 is fixedly installed on the upper part of the base 1 near the material distribution joint 4. A drive motor 51 is installed on one side of the bracket 5. A friction wheel 52 is connected to the output shaft of the drive motor 51. A rolling wheel 53 is rotatably installed on the lower part of the bracket 5. At least two soft brushes 54 are evenly spaced inside the rolling wheel 53. The outer side of the friction wheel 52 is in contact with the outer side of the rolling wheel 53. When the drive motor 51 drives the friction wheel 52 to rotate, the rolling wheel 53 and the soft brushes 54 rotate accordingly.

[0023] Initially, the cable needs to be routed inside the equipment. First, one end of the cable is passed between the straightening wheels 3 on the right side of the equipment and then laterally passed between the coating plates 45 to the left. Then, the cable is passed through the soft brush 54 of the rolling wheel 53 and continues to be led out of the equipment to the left to connect with the external cable feeding device. When the cable feeding device is working, the cable will be pulled from right to left and continuously straightened by the rear straightening wheel 3. The feed pipe 42 connects with the external paint supply component, and the paint is fed into the dispensing connector 4. The paint output is adjusted by adjusting the pressure of the air inlet pipe 43. When the cable is pulled, the coating plate 45 will contact the cable surface and adhere the paint to the cable. The drive motor 51 is started to make the soft brush 54 in the rolling wheel 53 rotate. The soft brush 54 rotates at a specific speed. During this process, the soft brush 54 will maintain a rotating contact with the cable surface. In this step, the soft brush 54 will evenly spread the paint adhering to the cable surface onto the cable.

[0024] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 5 As shown, the upper part of the base 1 has a heating and straightening mechanism 6. Before the cable enters the coating station, it will pass through the heating and straightening mechanism 6. The heating and straightening mechanism 6 includes: a mounting base 61, heating rollers 62, and springs 63. On the right side of the base 1, near the straightening rollers 3, there is a mounting base 61. The mounting base 61 has a cross groove inside, which provides an installation and support area for the heating rollers 62. Four heating rollers 62 are installed in the cross groove of the mounting base 61. They can not only slide freely in the groove, but also achieve elastic connection with the mounting base 61 through the springs 63. This ensures that the heating rollers 62 can flexibly adjust their position when subjected to cable pressure, while maintaining continuous contact with the cable and the straightening effect. There are two sets of heating and straightening mechanisms 6, and the two sets of heating and straightening mechanisms 6 are arranged opposite each other. The two sets of heating and straightening mechanisms 6 ensure the effectiveness of heating and straightening.

[0025] The heating rollers 62 are equipped with embedded heating elements. These elements heat up rapidly after being powered on and transfer heat to the surface of the heating rollers 62. When the cable passes through the heating rollers 62, its surface is heated evenly. This not only helps to soften the material on the surface of the cable, making it easier to straighten, but also removes moisture and dirt from the surface of the cable, creating more favorable conditions for the subsequent coating process. A feeding gap is left between the intersections of the four heating rollers 62. This design ensures that the cable can pass smoothly through the heating and straightening mechanism 6 without being stuck or damaged by the rollers. At the same time, the size of the feeding gap can be adjusted according to actual needs to accommodate cables of different diameters or shapes.

[0026] In a preferred embodiment: such as Figure 1 , Figure 2 and Figure 6 As shown, it also includes: a drying chamber 7 located on the left side of the base 1; a partition 71 inclined inside the drying chamber 7, dividing the drying chamber 7 into two spaces; material passage holes 73 are opened in the lower left and upper right parts of the drying chamber 7, and both material passage holes 73 are connected to the lower space inside the drying chamber 7; a cable enters the lower space of the drying chamber 7 from the material passage hole on the right and exits from the material passage hole 73 on the left; a heat-conducting pipe 72 is arranged in the upper space inside the drying chamber 7, with one end of the heat-conducting pipe 72 exiting from the left side of the drying chamber 7 for connection to an external heat source. Next, the heat pipe 72 is connected to the lower space of the partition 71 through multiple branch pipes. Hot air is introduced into the lower part of the partition 71 from the heat pipe 72, so that the hot air can be evenly distributed in the entire drying chamber 7, thereby achieving comprehensive drying of the cable wires entering the drying chamber 7. A guide wheel 8 is rotatably installed on the lower left side of the inner side of the base 1. The purpose of setting the guide wheel 8 is to guide the wiring direction of the cable, so that the cable is orderly transferred from the rear processing station of the device according to the preset path.

[0027] Specifically, after the coated cable passes through the roller 53, it will enter the drying chamber. Before the cable enters the drying chamber, heat is introduced into the drying chamber 7 through the heat pipe 72 to keep the internal temperature within a suitable range for drying the coating. The cable passes through the drying chamber 7 at a uniform speed to dry the coating. The dried cable passes down through the material passage 73 on the left side and exits from the drying chamber 7, and then passes around the lower part of the lead wheel 8.

[0028] In a preferred embodiment: such as Figure 1-2 As shown, it also includes a collection frame 9. The collection frame 9 is provided on the inner side of the base 1. The opening of the collection frame 9 faces upward and is arranged below the coating plate 45 and the soft brush 54. This layout ensures that any paint or impurities dripping from the coating plate 45 or the soft brush 54 during the coating and cleaning process can be directly captured by the collection frame 9, thereby avoiding the contamination of other parts of the device or the surrounding environment by these substances. It also eliminates the need for operators to frequently clean various parts of the device, thereby improving work efficiency and ease of operation.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
