It can improve production efficiency, reduce production costs, improve the performance and quality of cables, and meet the growing market demand. This plan specifically involves cable core coating and molding. Device; The existing cable core coating molding device has certain limitations in practical applications. First, different coating layers often need to be processed using special equipment, which leads to poor versatility of the equipment and the need to switch different equipment. This limitation not only increases the floor space and equipment investment of the production line, but also reduces production efficiency. Secondly, when it is necessary to change the coating thickness of the cable core, the operator needs to make cumbersome parameter adjustments, which is not only time-consuming, but also increases the coating thickness. It is necessary to sacrifice the winding and unwinding speed of the wire core, affecting the production efficiency of the cable. In addition, when using molten materials for coating, the existing device is prone to uneven discharge. This unevenness will cause the coating thickness of the cable core to be different, thereby affecting the overall performance and safety of the cable. Summary of the invention

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 12As shown, a cable core coating molding device comprises a base 1, the upper part of the base 1 is fixedly connected to a support plate 2, and the front part of the base 1 is rotatably connected to a winding roller 3, the rear part of the base 1 is rotatably connected to an unwinding roller 4, and the front top of the base 1 is fixedly connected to a water tank 5, the top of the base 1 is fixedly connected to two orifice plates 6, the top inner sides of the two orifice plates 6 are respectively slidably connected to the two ends of a cable 7, the upper middle part of the base 1 is fixedly connected to a material box 8, the rear part of the support plate 2 is fixedly connected to a motor 9, the front part of the motor 9 is rotatably connected to the inner side of the support plate 2, and the front part of the motor 9 is fixedly connected to a large gear 10, the bottom of the large gear 10 is meshedly connected to a small gear 11, the front part of the small gear 11 is fixedly connected to a bracket 12, and the top and bottom of the front end of the bracket 12 are both rotatably connected to a wire reel 13;

[0027] The top of the base 1 is fixedly connected to the extrusion port 14, the inner rear part of the extrusion port 14 is slidably connected to the moving block 15, the front part of the large gear 10 is fixedly connected to the spiral plate 16, the front end of the spiral plate 16 is fixedly connected to the driving wheel 19, the bottom of the driving wheel 19 is meshed and connected to the driven wheel 20, the bottom of the driven wheel 20 is fixedly connected to the spiral plate 2 17, the top of the spiral plate 2 17 is rotatably connected to the inner side of the cross plate 18, the outer sides of the spiral plates 16 and 17 are both rotatably connected to the material box 8, and the front end of the cross plate 18 is fixedly connected to the material box 8.

[0028] The inner front end of the bracket 12 is fixedly connected to the bearing 21, the inner side of the bearing 21 is fixedly connected to the sleeve 22, the front outer side of the sleeve 22 is provided with two annular protrusions, the rear part of the sleeve 22 is fixedly connected to the support plate 2, and the bottom of the support plate 2 is provided with a circular hole running through the front and back. The sleeve 22 can provide support for the bearing 21 and the bracket 12, and the bracket 12 can be rotated in place through the action of the bearing 21 without falling.

[0029] The inner rear part of the extrusion port 14 is fixedly connected to the sealing ring 23, and the inner side of the sealing ring 23 is slidably connected to the moving block 15. The sealing ring 23 can block the gap between the extrusion port 14 and the moving block 15 to prevent the molten material in the gap from overflowing.

[0030] Two threaded rods 24 are rotatably connected to the rear of the extrusion port 14, and the middle parts of the two threaded rods 24 are meshed and connected to the moving block 15. During the rotation process, the two threaded rods 24 can drive the moving block 15 to move under the action of the threads, thereby adjusting the gap between the front end of the moving block 15 and the extrusion port 14.

[0031] Three outer shells 26 are slidably connected to the inner side of the moving block 15, and a plurality of rollers 27 are rotatably connected to the inner sides of the three outer shells 26. The tops of the front and rear ends of the three outer shells 26 are fixedly connected to the moving block 15, and the tops of the two springs 25 are fixedly connected to the moving block 15. The outer shells 26 can move in the axial direction of the moving block 15 under the action of the springs 25, and drive the rollers 27 connected thereto to move together. The three outer shells 26 simultaneously drive the connected rollers 27 to gather together, so as to constrain the passing cables 7 to the center of the moving block 15 without affecting the winding and unwinding of the cables 7.

[0032] A plurality of guide plates 28 are fixedly connected to the inner side of the extrusion port 14. The guide plates 28 are spiral in shape and are evenly distributed at the extrusion port 14. After the molten material enters the interior of the extrusion port 14, it will flow toward the front of the extrusion port 14 under the action of pressure. During the flow, it is guided by the guide plates 28 to mix the molten material, thereby making the discharge more uniform.

[0033] The rear of the extrusion port 14 has two T-shaped holes, and the upper and lower sides of the rear of the moving block 15 have screw holes. The front of the threaded rod 24 can rotate in the T-hole of the extrusion port 14, and while rotating, the moving block 15 is driven by the thread to move forward or backward.

[0034] It should be noted that the present invention is a cable core coating molding device. When in use, one end of the cable 7 is passed through the sleeve 22 and the orifice plate 6 from the unwinding roller 4 in sequence, and then passed through the inner side of the moving block 15, and then passed through another orifice plate 6 and the water tank 5 in sequence, and then rolled up on the winding roller 3. While the cable 7 is passed through the sleeve 22, one end of the windings on the two wire rolls 13 is passed through the orifice plate 6 and the moving block 15 and subsequent components together with the cable 7, and finally rolled up on the winding roller 3 together with the cable 7;

[0035] Then, the motor 9 is started. When the motor 9 rotates, it drives the large gear 10 to rotate. The large gear 10 drives the small gear 11 to rotate. The small gear 11 drives the bracket 12 connected thereto to rotate. The bracket 12 is constrained by the bearing 21 and the sleeve 22 and can only rotate in the original position. When the bracket 12 rotates, it drives the two wire reels 13 connected thereto to rotate, so that the two wire reels 13 revolve around the axis of the cable 7 and wrap the winding material around the outside of the cable 7 while rotating. When the cable 7 is being wrapped, the two wire reels 13 will also rotate under the traction of the winding material, thereby continuously unwinding.

[0036] The motor 9 rotates while driving the spiral plate 16 and the driving wheel 19 to rotate. The driving wheel 19 drives the spiral plate 2 17 to rotate through the driven wheel 20. The spiral plate 2 17 is constrained by the cross plate 18 and can only rotate in situ. After the molten material to be wrapped in the outer layer of the cable 7 is melted and put into the material box 8, the molten material moves toward the direction of the spiral plate 2 17 under the action of the spiral plate 16, and after moving to the position of the spiral plate 2 17, it moves to the inside of the extrusion port 14 under the action of the spiral plate 2 17. After entering the extrusion port 14, the molten material will move toward the front of the extrusion port 14 under the action of the pressure difference, and will be blocked and guided by the guide plate 28 during the movement, so that the molten material is spirally moved and mixed inside the extrusion port 14 to make it more uniform.

[0037] The molten material is extruded in a circular shape through the gap between the front of the extrusion port 14 and the moving block 15, and wraps the cable 7 inside thereof. After the molten material moves out of the extrusion port 14, it contacts with the air and exchanges heat, causing it to lose a portion of heat, so that it is in a state where it can adhere to the cable 7 but not drip. Then, the molten material passes through another orifice plate 6, and is pressed against the outside of the cable 7 by the holes of the orifice plate 6. After passing through the water tank 5, it is cooled and rolled up by the winding roller 3.

[0038] When the wrapping thickness of the outer side of the cable 7 needs to be adjusted, the two threaded rods 24 can be rotated. While the threaded rods 24 are rotating, the moving block 15 is moved by the action of the thread. The moving block 15 is constrained by the extrusion port 14 and the two threaded rods 24 and can move linearly along its own axis. By changing the rotation direction of the two threaded rods 24, the moving direction of the moving block 15 can be controlled. By controlling the moving block 15 to move in the direction of the sleeve 22, the gap between the moving block 15 and the front part of the extrusion port 14 increases, so that the amount of material discharged at the same time increases, thereby making the molten material attached to the cable 7 thicker. By controlling the moving block 15 to move in the direction of the water tank 5, the gap between the moving block 15 and the front part of the extrusion port 14 decreases, and the amount of molten material that can pass through at the same time decreases, making the molten material attached to the cable 7 thinner.

[0039] The above embodiments of the present invention can achieve the following beneficial effects:

[0040] 1. The present invention provides a bracket 12 and a wire coil 13, so that the cable core coating molding device can realize two coating operations at the same time without switching equipment, thereby improving production efficiency, reducing downtime in the production process, reducing equipment complexity and operating difficulty, and ensuring high consistency and stability of coating quality;

[0041] 2. By setting the large gear 10 and the small gear 11, the two coating modes of the cable core coating molding device share the same power, which simplifies the mechanical structure of the device. This design not only reduces the number of parts of the device, but also reduces the maintenance difficulty and cost of the device. At the same time, this shared power design also improves the operating efficiency and stability of the equipment, ensures the high consistency of the coating quality, and improves the reliability of the equipment;

[0042] 3. By setting the moving block 15, flexible adjustment of the coating thickness is achieved. In actual application, the operator can adjust the position of the moving block 15 according to the production needs and the specific requirements of the cable products, so as to control the thickness of the coating. This design not only improves the coating quality of the cable core, ensures the quality and consistency of the product, but also improves the molding efficiency. Through the function of flexibly adjusting the coating thickness, the device can better meet various production needs and improve the flexibility and efficiency of the cable production process.

[0043] 4. By setting the guide plate 28, the cable core coating molding device achieves more uniform discharge. The guide plate 28 enables the material to be mixed along a spiral path during the discharge process, thereby ensuring the uniformity of material distribution, avoiding the deviation and distortion of the material during the discharge process, and ensuring the stability and consistency of the cable core coating. The material can flow and complete mixing through the guidance of the guide plate 28, which not only improves the quality of the coating layer, but also improves the molding efficiency.

[0044] 5. By setting the extrusion port 14, the operator can flexibly thicken the coating of the cable core without slowing down the production speed. This adjustment mechanism will not affect the operating speed of the equipment, ensuring that the production efficiency is not affected, thereby improving the production efficiency. This design enables the operator to flexibly adjust the thickness of the coating while ensuring the efficiency and stability of the production process.
