Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable parts technology, and further to a novel heating and lifting device for automatic expansion of heat shrinkable parts. Background Technology

[0002] Heat-shrinkable molded kits are an important supporting product in the wire and cable industry, widely used in cable connection, insulation protection, corrosion protection and sealing. These kits are typically made of heat-shrinkable materials such as radiation-crosslinked polyolefins, and the production process involves four key steps: extrusion, injection molding, irradiation, and expansion. The expansion process, as the final processing step, directly determines the dimensional accuracy, mechanical properties, and insulation characteristics of the heat-shrinkable kit, and has a decisive impact on product quality.

[0003] In existing technologies, the expansion process typically involves manually placing the irradiated molded sleeve into an oven to soften it, then removing it for mechanical expansion. After expansion, the mold and sleeve are placed in water for cooling, and finally, the sleeve is manually demolded. This production method suffers from high labor intensity, low efficiency, and the risk of burns. It also makes it difficult to guarantee product consistency and stability. Furthermore, currently, the expansion of heat-shrinkable molded sleeves mainly employs two methods: air expansion and mechanical expansion. Air expansion is suitable for small-diameter products, expanding by blowing air, but it can easily lead to uneven wall thickness. Mechanical expansion is suitable for larger-diameter products, ensuring uniform wall thickness, but the expansion width is limited by the length of the expansion rod. Both methods have significant limitations, making it difficult to achieve high-quality, large-scale continuous production.

[0004] In view of the problems existing in the prior art, there is an urgent need to design a new heating and lifting device for automatic expansion of heat shrink parts, so as to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to provide a novel heating and lifting device for automatic expansion of heat shrinkable parts, which can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a novel heating and lifting device for automatic expansion of heat-shrinkable parts, comprising:

[0007] A frame, wherein a feeding station, a heating station and a cooling station are provided on the frame;

[0008] A rotating mechanism is mounted on the frame and can rotate circumferentially under a driving action to move the molded sleeve between the heating station and the cooling station;

[0009] An expansion mechanism is provided on the rotating mechanism at a position corresponding to the feeding station, and the expansion mechanism is used to fit and expand the mold sleeve to be expanded.

[0010] A heating lifting mechanism is mounted on a frame and includes a heating immersion container corresponding to the heating station.

[0011] A cooling lifting mechanism is mounted on the frame and is configured corresponding to the cooling station.

[0012] In some embodiments, the heating lifting mechanism further includes a gantry, a lifting frame, and a hydraulic device. Multiple gantry frames are vertically arranged on the frame, the lifting frame is slidably arranged on the gantry, and the hydraulic device is correspondingly connected to the heating immersion container through a transmission component, so that the heating immersion container can move up and down along the gantry.

[0013] By setting up a hydraulic device to drive the lifting and lowering of the heating immersion container, combined with the gantry guide, the lifting and lowering of the heating immersion container can be smoothly and accurately controlled. This allows the heating immersion container to dock or separate from the expansion mechanism at an appropriate speed, avoiding impact and ensuring a smooth and reliable heating process for the molding sleeve. It is suitable for high-load environments, has a simple structure, is stable and reliable, and can be used in harsh environments.

[0014] In some embodiments, the heated immersion container is provided with a cleaning port and / or an overflow port.

[0015] The addition of a cleaning port facilitates regular cleaning of the container's interior, removing impurities and maintaining heating efficiency and operational safety. An overflow port prevents excessive heating medium from overflowing, thus enhancing safety.

[0016] In some embodiments, an opening is provided at one end of the heated immersion container near the expansion mechanism, and a liquid collection tray is provided at the other end of the heated immersion container away from the opening. The liquid collection tray is used to collect liquid flowing out or overflowing from the heated immersion container.

[0017] By setting up a collection tray, the heating medium dripping from the heating immersion container and molding sleeve can be effectively collected, thereby preventing it from splashing onto other parts of the equipment or the work area. This reduces medium loss, avoids the risk of slipping, and keeps the environment clean.

[0018] In some embodiments, the opening is surrounded by a conical disk, the larger diameter end of which is away from the body of the heated immersion container, and the smaller diameter end of which is close to and connected to the body of the heated immersion container.

[0019] By setting a conical disk around the opening, the conical disk guides and shields the flow, reducing the loss of heat from the container when the heated immersion container rises to wrap the molding sleeve. At the same time, it further suppresses the splashing of the heating medium, which helps to save energy and maintain a stable operating temperature.

[0020] In some embodiments, the heated immersion container is provided with a plurality of heating elements, which extend along the opening direction of the heated immersion container and are arranged in a ring-shaped and uniform manner.

[0021] In some embodiments, the heating immersion container is provided with a heating rod flange and an upper flange, and the heating element is disposed between the heating rod flange and the upper flange.

[0022] The standardized flange installation method facilitates the positioning, fixing, and subsequent replacement and maintenance of the heating element, while also ensuring a tight seal at the container opening to prevent media leakage.

[0023] In some embodiments, the heated immersion container has a double-layer structure, and the double-layer structure is provided with heat-insulating material.

[0024] By incorporating insulation material into a double-layered hollow insulation structure, the heat loss from the heated immersion container to the external environment is effectively reduced, thereby lowering the energy consumption required to maintain the operating temperature. This enables the device to meet energy-saving and environmentally friendly production requirements, achieving the technical effect of maintaining a stable temperature.

[0025] In some embodiments, the heated immersion container is also equipped with a temperature sensor.

[0026] By setting up a temperature sensor, real-time monitoring and feedback control of the heating medium temperature are achieved. Through its linkage with the heating system, the medium temperature is precisely maintained within the optimal range required by the process, thereby avoiding material deterioration due to excessively high temperatures or insufficient softening due to excessively low temperatures, thus ensuring the stability and consistency of product quality.

[0027] Compared with the prior art, the novel heating and lifting device for automatic expansion of heat shrink parts provided by this utility model has the following beneficial effects:

[0028] 1. The novel heating and lifting device for automatic expansion of heat shrink parts provided by this utility model integrates feeding, heating, expansion, cooling and rotation mechanisms in the same device, thereby realizing full automation from putting in the unexpanded part to taking out the finished part. It replaces the traditional manual transfer, heating and expansion operation mode, greatly improving production efficiency. At the same time, the heating and cooling functions are integrated into the rotation mechanism, making the overall structure compact, significantly reducing the equipment floor space and improving space utilization.

[0029] 2. The novel heating and lifting device for automatic expansion of heat shrink parts provided by this utility model, by setting two heating stations and distributing them at right angles to the feeding and cooling stations, and in conjunction with the rotating mechanism, can form an efficient continuous production cycle. When one molded sleeve is heated at station A, the other molded sleeve can be fed or cooled at station B, which greatly reduces the waiting time, realizes near-continuous production, doubles the production capacity, and greatly improves the heating efficiency.

The frame 10 is provided with a loading station 11, a heating station 12, and a cooling station 13. The rotating mechanism 40 is mounted on the frame 10. The expansion mechanism 20 is mounted on the rotating mechanism 40 at a position corresponding to the loading station 11. The expansion mechanism 20 is used to fit and expand the molded sleeve to be expanded. The heating and lifting mechanism 30 is mounted on the frame 10 and includes a heating immersion container 60, which corresponds to the heating station 12. The cooling and lifting mechanism 50 is mounted on the frame 10 and is positioned corresponding to the cooling station 13.

[0043] In one embodiment, refer to the appendix to the specification.

Multiple gantry frames 31 are vertically arranged on the frame 10, the lifting frame 32 is slidably arranged on the gantry frame 31, and the hydraulic device is correspondingly connected to the heating immersion container 60 through a transmission component so that the heating immersion container 60 can move up and down along the gantry frame 31.

[0044] Specifically, the gantry 31 is preferably welded from steel profiles and is vertically fixed to the frame 10. The lifting frame 32 slides with the guide rail on the gantry 31 and can make precise vertical lifting and lowering movements along the gantry 31 under the drive of the hydraulic device. The hydraulic device is mainly a hydraulic device, which is connected to the heated immersion container 60 through transmission components such as steel cables, chains 33 or rigid push rods.

[0045] In one embodiment, refer to the appendix to the specification. Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, the heating immersion container 60 is provided with a cleaning port 621 and / or an overflow port 622.

[0046] Specifically, the cleaning port 621 is usually located below the side wall or bottom of the heating immersion container 60. It is used to discharge old heating medium and wastewater when cleaning the container. It is connected to a drain pipe and valve. The cleaning port 621 is used to clean the inside of the heating immersion container 60, which can prevent the accumulation of degradation products or impurities of the heating medium and maintain heating efficiency. The overflow port 622 is located above the highest working liquid level on the side wall of the heating immersion container 60. Its main functions are safety pressure relief and liquid level control. When too much heating medium is added to the heating immersion container 60 or the medium volume expands due to temperature rise, the excess liquid can be discharged through the overflow port 622 to prevent the pressure inside the heating immersion container 60 from being too high and to protect the structure of the heating immersion container 60.

[0047] In one embodiment, refer to the appendix to the specification. Figure 3 and Figure 4 Based on the above embodiments, an opening is provided at one end of the heating immersion container 60 near the expansion mechanism 20, and a liquid collection tray 61 is provided at the other end of the heating immersion container 60 away from the opening.

[0048] Specifically, the opening on the heated immersion container 60 near the expansion mechanism 20 is slightly larger than the largest size of the molded sleeve to be heated, to ensure that the molded sleeve can move smoothly without interference during the lifting process. A liquid collection tray 61 is provided at the bottom of the heated immersion container 60. The liquid collection tray 61 is used to collect excess heat-conducting medium dripping from the container and the surface of the heated molded sleeve, to keep the equipment and work site clean, and to realize the recycling of the medium.

The large-diameter end of the conical disk 62 is away from the body of the heating immersion container 60, and the small-diameter end of the conical disk 62 is close to and connected to the body of the heating immersion container 60.

[0050] Specifically, a conical disk 62 is fixed around the edge of the opening. The large-diameter end of the conical disk 62 is far away from the body of the heated immersion container 60, while the small-diameter end of the conical disk 62 is close to and connected to the body of the heated immersion container 60. The conical disk 62 can play a guiding role during the rising process of the heated immersion container 60, and the auxiliary expansion mechanism 20 is aligned and descends smoothly into the heated immersion container 60, while effectively reducing the evaporation and splashing of the heat medium inside the container.

The plurality of heating elements 64 extend along the opening direction of the heating immersion container 60 and are arranged in a ring uniformly.

[0054] Specifically, the extension length of the heating element 64 is usually matched with the depth of the effective heating zone inside the heating immersion container 60 to ensure that the key parts that need to be softened are completely in a uniform thermal field after the molded sleeve is immersed. In addition, the heating elements 64 are arranged in a ring to form a uniform and stable temperature field in the working medium inside the container, which is conducive to the uniform circumferential heating of the cylindrical or near-cylindrical molded sleeve and effectively prevents the problem of uneven deformation caused by excessive heating on one side.

Figure 1 and Figure 4 Based on the above embodiments, the heating immersion container 60 is provided with a heating rod flange 66 and an upper flange 67, and a heating element is provided between the heating rod flange 66 and the upper flange 67.

[0056] Specifically, the heating rod flange 66 is usually fixed at the bottom or side wall opening of the heating immersion container 60, and has multiple through holes for inserting the heating element 64 and providing it with initial positioning and support.
