Abstract
Description
Technical Field
[0001] This application relates to the field of resin wire production, and more particularly to a resin wire impregnation device and cable production equipment. Background Technology
[0002] Resin coating on wire surfaces is a crucial step in cable manufacturing, as its uniformity directly impacts the mechanical and electrical properties of the coating. Currently, when using resin baths for wire coating, the industry commonly faces the problem of uneven resin distribution on the wire surface. This manifests as significant localized differences in coating thickness, with some areas experiencing insufficient resin coverage or excessive resin buildup. This leads to reduced adhesion to the wire surface, unstable insulation performance, and other issues, severely affecting product reliability and lifespan.
[0003] Traditional resin baths typically employ a single-height or simply arranged guide roller structure, resulting in an overly straight path for the resin thread within the bath and a lack of effective dynamic adjustment during the impregnation process. This structure leads to unstable resin flow on the thread surface, insufficient contact time between the thread and resin, and difficulty in forming a continuous and uniform impregnation layer. Particularly in the application of high-viscosity resin materials, due to the poor resin flowability, rapid thread passage easily creates impregnation blind zones, significantly increasing the incidence of residual bubbles or voids. Furthermore, poor matching between thread movement speed and resin flow speed can easily cause turbulence on the thread surface, further exacerbating coating inhomogeneity. As thread production speeds continue to increase, the structural limitations of existing coating equipment become increasingly apparent, often requiring repeated adjustments to process parameters to maintain basic quality requirements, severely restricting production efficiency and product yield.

[0041] This application provides a resin line impregnation device, which includes a housing 100, a plurality of first rotating shafts 200, a plurality of second rotating shafts 300, and an outer cover 400. The housing 100 has a liquid-containing tank 110. The first rotating shafts 200 are rotatably mounted in the liquid-containing tank 110, and the second rotating shafts 300 are rotatably mounted in the liquid-containing tank 110. The first rotating shafts 200 and the second rotating shafts 300 are alternately arranged in the liquid-containing tank 110, and the axis of the second rotating shaft 300 is located in a first direction of the axes of two adjacent first rotating shafts 200.
[0042] See Figure 1 and Figure 3 As shown, the liquid tank 110 of the housing 100 contains resin, which is prepared for the wire impregnation seat. It should be noted that in order to achieve wire impregnation, both the first rotating shaft 200 and the second rotating shaft 300 are located below the resin level. Furthermore, the wire is sequentially wound around the outer surfaces of the first rotating shaft 200 and the second rotating shaft 300 from the feeding direction. Since the central axis of the second rotating shaft 300 is located in the first direction of the axes of the two adjacent first rotating shafts 200, that is, below the axes of the two first rotating shafts 200, and the height of the second rotating shaft 300 is lower than that of the first rotating shaft 200, the path that the wire travels in the liquid tank 110 can be increased, thereby increasing the residence time of the wire in the liquid tank 110 and making the impregnation more uniform.
[0043] Please continue reading. Figure 1 and Figure 3 As shown, in this embodiment, the first direction is the Z1 direction, that is, the direction of downward height. The first direction in which the axis of the second rotating shaft 300 is located between the axes of the two adjacent first rotating shafts 200 can be understood as the second rotating shaft 300 being located between the two first rotating shafts 200, and the height of the second rotating shaft 300 being lower than that of the first rotating shaft 200. Therefore, under this distribution, multiple first rotating shafts 200 and second rotating shafts 300 form a wave-shaped guide path.
[0044] In some embodiments, the axes of the first rotating shaft 200 and the first rotating shaft 200 may be located on the same horizontal plane or not on the same horizontal plane. That is, the first rotating shaft 200 does not necessarily have to be arranged parallel to each other. Similarly, the second rotating shaft 300 does not necessarily have to be arranged parallel to each other. In practice, the design can be carried out as needed, and no limitation is made here.
[0045] In one embodiment, the outer cover 400 is located in a second direction of the shell 100, and the outer cover 400 is used to cover the shell 100.
[0046] Please see Figure 2As shown, in order to prevent foreign objects from falling into the resin liquid in the liquid tank 110, an outer cover 400 is provided above the shell 100 to cover it, thereby blocking foreign objects from entering the liquid tank 110. The outer cover 400 also has a certain heat preservation function to prevent the resin liquid in the liquid tank 110 from losing temperature quickly and solidifying.
[0047] It should be noted that the second direction mentioned above is... Figure 1 and Figure 3 The Z2 direction shown is the upward direction of the height direction. It can be understood that the outer cover 400 is located above the shell 100.
[0048] A first handle 120 is fixedly provided on the outer wall of the shell 100 in the opposite direction.
[0049] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, during the installation and handling of the shell 100, in order to facilitate handling, a first handle 120 is fixedly installed on the outer wall of the shell 100 along its length. The shell 100 can be handled by the first handle 120. Specifically, if the shell 100 is heavy, the first handle 120 can be replaced with a lifting lug, and the shell 100 can be lifted and handled by a lifting device in conjunction with the lifting lug.
[0050] For example, the first handle 120 is U-shaped.
[0051] The outer cover 400 has a covering cavity, the shell 100 is located in the covering cavity, and a heating component 500 is provided inside the outer cover 400.
[0052] See Figure 3 As shown, since the resin liquid can only maintain its fluidity at a certain temperature, it will solidify if the temperature is too low. Therefore, a heating component 500 is installed on the inner wall of the outer cover 400. The heating component 500 heats the resin liquid in the liquid tank 110 to keep the resin liquid at a certain temperature, so as to prevent the resin liquid from solidifying due to the low temperature and failing to wet the wire.
[0053] In one embodiment, in order to reduce the cooling rate of the resin liquid in the liquid tank 110, a layer of heat-insulating material can be provided on the outer surface of the shell 100. Correspondingly, a layer of heat-insulating material can also be provided on the outer surface or inner wall of the outer cover 400 to reduce the cooling rate of the resin liquid.
[0054] The outer cover 400 includes a first cover 410, a second cover 420, and a hinge 430. The first cover 410 has a first cavity 411, and the second cover 420 has a second cavity 421. The second cover 420 is located on one side of the first cover 410 along the resin line conveying direction. The first cavity 411 and the second cavity 421 communicate to form the covering cavity. The hinge 430 is located between the first cover 410 and the second cover 420 and is used for rotatably connecting the first cover 410 and the second cover 420.
[0055] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, in this embodiment, in order to clean or add resin liquid to the liquid tank 110 at regular intervals, the outer cover 400 needs to be opened to a certain extent to facilitate cleaning and adding. Specifically, the outer cover 400 is composed of a first cover 410 and a second cover 420, and the first cover 410 and the second cover 420 are connected by a hinge 430, so that the second cover 420 can rotate relative to the first cover 410, thereby opening the outer cover 400 and exposing part of the shell 100 to facilitate adding resin liquid.
[0056] Please continue reading. Figure 3 As shown, the heating component 500 can be opened without hindering the heating of the outer cover 400. The shell will fix the heating component 500 on the inner top wall of the mounting component 510. At this time, the heating component 500 is located in the first cavity 411, so only the second cover 420 needs to be rotated to open the outer cover 400.
[0057] Furthermore, the first cavity 411 and the second cavity 421 are connected to form a cover cavity, and the shell 100 is located in the cover cavity. In this embodiment, both the shell 100 and the outer cover 400 are rectangular, and the first cavity 411 and the second cavity 421 are also rectangular.
[0058] A second handle 440 is fixedly provided on both the first cover 410 and the second cover 420.
[0059] See Figure 2 , Figure 4 , Figure 5 as well as Figure 6As shown, in order to facilitate the handling of the outer cover 400 and to facilitate the rotation of the second cover 420, a second handle 440 is fixedly provided on the opposite sides of the first cover 410 and the second cover 420. It can be understood that when it is necessary to manually rotate the second cover 420 relative to the first cover 410, one only needs to hold the first cover 410 to rotate the second cover 420 upward, thereby exposing part of the shell 100 to the outside.
[0060] The first cover 410 and the second cover 420 have clearance grooves 450 on their side walls facing away from each other.
[0061] See Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in order to prevent the outer cover 400 from colliding and interfering with the shell 100, a clearance groove 450 is provided on the frame of the first cover 410 and the second cover 420. The clearance groove 450 is used to avoid the first rotating shaft 200 and prevent the first cover 410 and the second cover 420 from colliding with the shell 100.
[0062] The height of the clearance groove 450 is H, and the height of the shell 100 is L, satisfying that: H > L.
[0063] See Figure 4 and Figure 7 As shown, in order to allow the wire to be immersed in the liquid tank 110 and to facilitate the immersion of the wire after immersion, a certain gap is required between the housing 100 and the outer cover 400. Specifically, a certain gap is required between the inner top wall of the clearance groove 450 and the upper surface of the housing 100. For this purpose, the height of the clearance groove 450 is denoted as H and the height of the housing 100 is denoted as L. H needs to be greater than L so that there is a gap between the inner top wall of the clearance groove 450 and the upper surface of the housing 100 for the wire to enter or exit. It can be understood that the difference between H and L should be at least greater than the diameter of the wire to prevent the wire to be immersed and the immersed wire from scraping against the housing 100 and the inner top wall of the clearance groove 450, thereby affecting the quality of the final resin wire.
[0064] The heating assembly 500 includes a mounting member 510 fixedly installed on the inner wall of the covered cavity, and an electric heating element 520 is fixedly installed at the end of the mounting member 510 away from the inner wall of the covered cavity.
[0065] In this embodiment, the heating component 500 is fixedly installed on the inner bottom wall of the first cover 410. Specifically, the heating component 500 includes a mounting member 510, and an electric heating element 520 is fixedly installed at the end of the mounting member 510. The electric heating element 520 heats the resin liquid in the liquid tank 110. It can be understood that the electric heating element 520 heats the air inside the cover 400, and the heat is transferred to the resin liquid in the liquid tank 110 through the air, thereby achieving the heating of the resin liquid.
[0066] For example, the heating element 520 can convert electrical energy into heat energy, for example, by using a heating wire as a heat source, or other components that can convert electrical energy into heat energy while meeting temperature requirements.
[0067] Multiple annular grooves (not shown in the figure) are formed on both the circumferential surface of the first rotating shaft 200 and the circumferential surface of the second rotating shaft 300.
[0068] In one embodiment, if multiple wires are being impregnated, in order to prevent the wires from tangling or touching each other and affecting the impregnation effect, annular grooves (not shown) are evenly spaced along the axial direction on the outer surfaces of the first rotating shaft 200 and the second rotating shaft 300, thereby separating the individual wires from each other.
[0069] This application also provides a cable production equipment, which includes any of the resin wire entry devices described above.
