Description

Technical Field

[0001] This utility model relates to the field of heat shrinking technology for insulating sleeves, specifically a heat shrinking device for cable insulating sleeves. Background Technology

[0002] During the manufacturing process, cables need to be fitted with an insulating sleeve on their outer wall to ensure their safe use.

[0003] To improve processing efficiency, heat shrinking is now commonly used to fit the insulation sleeve onto the outer wall of the cable. This involves selecting a shrinkable insulation sleeve, first placing the sleeve on the outside of the cable, and then heating the sleeve. When heated, the insulation sleeve shrinks radially, thus tightly wrapping the insulation sleeve around the outer wall of the cable.

[0004] For example, in the patent application number 202322270543.2 entitled "A Heat Shrinking Device for Cable Insulation Sleeves", the cable with an insulation sleeve is inserted into a heating box, and then the insulation sleeve is heated by two revolving heating fins. Although this can achieve the effect of heat shrinking, the heating of the insulation sleeve by the heating fins is not uniform during the revolution, which leads to uneven shrinkage of the insulation sleeve. As a result, the insulation sleeve is prone to loosening on the outer wall of the cable when it is used, thus reducing the heat shrinking quality. Therefore, we propose a heat shrinking device for cable insulation sleeves. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely.

[0025] This application provides a heat-shrinking device for cable insulation sleeves, which solves the problem of uneven shrinkage caused by uneven heating of the insulation sleeve. The heating mechanism heats the second copper ring 203, which in turn heats the dielectric oil 204. The dielectric oil 204 then heats the first copper ring 202, allowing the heat to be transferred through the dielectric oil 204. This ensures that the first copper ring 202 is heated evenly, thereby improving the heat shrinking quality of the sleeve.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a heat shrinking device for cable insulation sleeves.

[0028] According to the appendix Figure 1 As shown in Figure 3, the heating box 101 includes a heating chamber 101, a heat conduction mechanism and a guide mechanism. The front of the heating chamber 101 has an insertion cavity 102 for the cable to enter. Then, the heat conduction mechanism heats and shrinks the sleeve, and finally the cable leaves the insertion cavity 102 through the guide mechanism.

[0029] In a preferred embodiment, a heat-conducting mechanism is disposed inside the insertion cavity 102. The heat-conducting mechanism includes a first copper ring 202 and a second copper ring 203. An annular groove 201 is formed inside the heating chamber 101. The first copper ring 202 is fixedly connected to the inner wall of the annular groove 201, and the second copper ring 203 is fixedly connected to the inner wall of the annular groove 201. The outer diameter of the first copper ring 202 is smaller than the outer diameter of the second copper ring 203. Medium oil 204 is disposed between the first copper ring 202 and the second copper ring 203. A heating mechanism is disposed inside the heating chamber 101, and the second copper ring 203 is heated by the heating mechanism. The heating process allows the second copper ring 203 to heat the medium oil 204, which in turn heats the first copper ring 202. This heat transfer from the medium oil 204 ensures that the first copper ring 202 is heated evenly, allowing the sleeve passing through the first copper ring 202 to shrink evenly to the outer wall of the cable. This improves the heat shrinking quality of the sleeve. Furthermore, the boiling point of the medium oil 204 is higher than the temperature required for the sleeve to shrink, preventing boiling of the medium oil 204 between the first copper ring 202 and the second copper ring 203, thus ensuring the stability of the heat conduction mechanism.

[0030] The heating mechanism includes heating fins 303. An installation cavity 301 is provided inside the annular groove 201. The heating fins 303 are fixedly connected to the outer wall of the second copper ring 203. A heating device 302 is installed inside the installation cavity 301. The output end of the heating device 302 is connected to the heating fins 303. By energizing the heating device 302, the heating fins 303 can heat the second copper ring 203. The heating device 302 is electrically connected to an external power source through an external switch, which facilitates the operator's control of the heating device 302 and improves the safety and convenience of operating the heating device 302.

[0031] The guiding mechanism is located inside the heating box 101. The guiding mechanism includes multiple extrusion rods 401. The multiple extrusion rods 401 are located inside the heating box 101. An extrusion mechanism is provided between the extrusion rods 401 and the heating box 101. After the insulating sleeve is heat-shrinked on the outer wall of the cable, it moves out of the insertion cavity 102 through the multiple extrusion rods 401.

[0032] The extrusion mechanism includes a movable rod 501, which is fixedly connected to the outer wall of the extrusion rod 401. An movable hole 502 is provided on the inner wall of the insertion cavity 102. The outer wall of the movable rod 501 is movably inserted into the inner wall of the movable hole 502. An movable cavity 503 is provided on the inner wall of the movable hole 502. A movable plate 504 is slidably connected to the inner wall of the movable cavity 503. The outer wall of the movable plate 504 is fixedly connected to one end of the movable rod 501. A spring 505 is provided between the movable plate 504 and the inner wall of the movable cavity 503. An adjustment mechanism is provided inside the movable cavity 503. Through the elastic action of the spring 505, the movable plate 504 is constantly compressed by the spring 505. With the connection of the movable rod 501, the multiple extrusion rods 401 tend to move relative to each other, thereby clamping the cable between the multiple extrusion rods 401 and ensuring that the cable stably exits from the insertion cavity 102.

[0033] The adjustment mechanism includes an adjustment plate 801, the outer wall of which is slidably connected to the inner wall of the movable cavity 503. A spring 505 is disposed between the movable plate 504 and the adjustment plate 801. The outer wall of the adjustment plate 801 is provided with a moving mechanism, which includes an adjustment bolt 803. The outer wall of the heating box 101 has a threaded hole 802, the interior of which is connected to the interior of the movable cavity 503. The outer wall of the adjustment bolt 803 is threadedly connected to the inner wall of the threaded hole 802. One end of the adjustment bolt 803 is rotatably connected to the outer wall of the adjustment plate 801. By rotating the adjustment bolt 803 and engaging it with the inner wall of the threaded hole 802, the adjustment plate 801 can be moved, thereby adjusting the compressive strength of the spring 505 on the movable plate 504. Thus, the position of the adjustment plate 801 can be adjusted according to the size of the cable.

[0034] The outer wall of the extrusion rod 401 is provided with multiple ball holes 601, and the inner wall of each ball hole 601 is movably fitted with a ball 602. The ball 602 makes the cable move more smoothly between the multiple extrusion rods 401.

[0035] The front of the extrusion rod 401 is fixedly connected to the inclined rod 701, which is inclined. The inner wall of the insertion cavity 102 is provided with a slot 702. The position of the inclined rod 701 corresponds to the position of the slot 702. The inclined rod 701 facilitates the guidance of the heat-shrinked cable to the multiple extrusion rods 401, thereby improving the smoothness of the cable movement in the insertion cavity 102.
