[0002] In the production of wires and cables, heat shrink packaging is a crucial step in ensuring the insulation performance of the product. Traditional heat shrink equipment often uses a fixed heating method, which suffers from uneven heating and low heat shrinking efficiency. This can easily lead to quality defects such as localized overheating or insufficient shrinkage of the wire insulation layer. Although existing technologies employ rotary heat shrink devices, they often suffer from technical bottlenecks such as incomplete heating coverage and low heat conduction efficiency. Furthermore, they lack effective temperature control and safety protection measures. In addition, the structural design of traditional equipment often results in high energy consumption and inconvenient operation, making it difficult to meet the requirements of modern wire and cable production for high efficiency, high quality, and energy conservation and environmental protection. Therefore, there is an urgent need to develop a packaging heat shrink device that can achieve uniform heating, efficient heat shrinking, and safety and reliability to solve the many problems existing in the current technology.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] See Figure 1-3 A heat shrink packaging device for wire production includes: a first support plate 1, a heat shrink tub 3 rotatably connected to the inner wall of the first support plate 1, a second support plate 5 fixedly connected to the top of the surface of the heat shrink tub 3, and an external fixing frame provided on the left side of both the first support plate 1 and the second support plate 5. The left side of the first support plate 1 and the second support plate 5 is fixedly connected to the external fixing frame, and the external fixing frame is used to fix the first support plate 1 and the second support plate 5 and keep them stationary.

[0019] Uniform heat shrink packaging is achieved through the rotation of the heat shrink tub 3 and the linkage of the heating coil 4. After the rotating motor 10 is started, the first rotating rod 11 drives the mating gear 12 to rotate. Since the mating gear 12 meshes with the gear ring 2, the heat shrink tub 3 rotates accordingly. At the same time, the cylindrical cam 803 at the top of the first rotating rod 11 rotates synchronously, and its return groove 804 pushes the driven rod 805 to move left and right, causing the heating coil 4 to slide back and forth along the slide groove 802 of the limiting plate 7. The combination of the rotation of the heat shrink tub 3 and the axial movement of the heating coil 4 ensures that the insulation layer of the wires wound on the surface of the tub is heated evenly, avoiding local overheating or insufficient shrinkage. The heat-conducting coil array is embedded in the insulating material, which not only ensures efficient heat conduction but also prevents the risk of leakage.

[0020] The heat shrink tub 3 is fixedly connected to both the top and bottom with mounting covers 13. A feed inlet 6 is provided through the top of the mounting cover 13. A third support plate 9 is fixedly connected to the right side of the first support plate 1. A first rotating rod 11 is rotatably connected to the inner wall of the third support plate 9. A mating component 8 is provided at the top of the first rotating rod 11. A limit plate 7 is fixedly connected to the right side of the bottom of the second support plate 5. A rotating motor 10 is fixedly connected to the bottom of the third support plate 9. The output end of the rotating motor 10 is fixedly connected to the bottom of the first rotating rod 11 via a coupling. The mating component 8 includes a cylindrical cam 803. A folding groove 804 with connected ends is provided on the surface of the cylindrical cam 803. A toothed ring 2 is fixedly connected to the bottom of the surface of the heat shrink tub 3. The top of the toothed ring 2 does not contact the bottom of the limit plate 7. The top of the first rotating rod 11 is connected to... The bottom of the cylindrical cam 803 is fixedly connected; the surface of the limiting plate 7 is provided with a moving block 801, and the top of the moving block 801 is provided with a sliding groove 802. The groove wall of the sliding groove 802 is slidably connected to the surface of the limiting plate 7. The left side of the moving block 801 is fixedly connected with a heating coil 4, and the right side of the moving block 801 is fixedly connected with a driven rod 805. The right end of the driven rod 805 is slidably connected to the groove wall of the folding groove 804. The surface of the heat shrink tub 3 is slidably connected to the inner ring of the heating coil 4. The surface of the first rotating rod 11 is fixedly connected with a mating gear 12, and the surface of the mating gear 12 meshes with the surface of the gear ring 2. The outer ring of the heating coil 4 is an insulating material, which is extruded polystyrene. The inner ring of the heating coil 4 is a heat-conducting coil array, and the heat-conducting coil array is partially embedded inside the insulating material.

[0021] The first support plate 1 and the second support plate 5 are kept static by an external fixing frame, while the heat shrink tub 3 maintains dynamic balance during rotation. When the heat shrink tub 3 rotates, the moving block 801 of the heating coil 4 is restricted by the trajectory of the return groove 804, forming a regular reciprocating motion. The meshing transmission ratio design of the gear ring 2 and the mating gear 12 makes the rotation speed of the heat shrink tub match the moving frequency of the heating coil, ensuring heat shrinking efficiency. The limiting plate 7 not only constrains the path of the moving block 801, but also reduces friction loss by not contacting the gear ring 2. The extruded polystyrene insulation layer forms a heat insulation barrier on the outer ring of the heating coil 4 to prevent heat leakage from damaging the support structure. At the same time, the inner ring heat-conducting array directly acts on the wire insulation layer to achieve precise temperature control.

[0022] Through the coordinated movement of the cylindrical cam 803 and the gear ring 2, when the rotating motor 10 drives the first rotating rod 11, it works with the gear 12 to drive the heat shrink tub 3 to rotate at a constant speed. The return groove 804 of the cylindrical cam 803 converts the rotation into the linear movement of the heating coil 4 through the driven rod 805. This linkage design allows the heating area to cover the entire surface of the heat shrink tub 3, and the moving speed is synchronized with the rotation speed of the tub, avoiding heat shrink blind spots. The dual function of the insulating material (outer ring heat insulation and inner ring heat conduction) protects the internal components of the device and improves the heat conduction efficiency. In addition, the feed port 6 of the mounting cover 13 facilitates continuous feeding, and the external fixing frame ensures that the support structure does not shift during high-speed operation, thus achieving efficient and stable production line heat shrink packaging.

[0023] In this application, the heat shrink packaging device for wire production achieves uniform heat shrink packaging through the linkage of the rotation of the heat shrink tub 3 and the heating coil 4. Its core lies in the coordinated movement of the cylindrical cam 803 and the gear ring 2. After starting the rotating motor 10, the first rotating rod 11 drives the mating gear 12 to rotate, causing the heat shrink tub 3 to rotate. Simultaneously, the return groove 804 of the cylindrical cam 803 pushes the driven rod 805 to move left and right, causing the heating coil 4 to slide back and forth along the sliding groove 802 of the limiting plate 7, ensuring uniform heating of the wire insulation layer. The meshing transmission ratio between the gear ring 2 and the mating gear 12 ensures that the rotational speed of the heat shrink tub and the movement frequency of the heating coil are synchronized. The heating coil 4 is made of extruded polystyrene insulation material to prevent leakage and reduce heat loss. The inner ring heat-conducting coil array acts directly on the wire to improve heat conduction efficiency. The limiting plate 7 constrains the movement path of the moving block 801 and does not contact the toothed ring 2 to reduce friction loss. The feed port 6 of the mounting cover 13 facilitates continuous feeding. The external fixing frame ensures that the first support plate 1 and the second support plate 5 remain stable during operation. The overall design achieves efficient and precise heat shrink packaging through the combination of rotation and linear motion, which is suitable for assembly line production.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
