Description

Technical Field

[0001] This application relates to the field of cable wrapping technology, and in particular to a fully automatic integrated wrapping machine for low-smoke halogen-free battery connecting cables for energy storage systems. Background Technology

[0002] Cable sheathing is a crucial manufacturing step that involves coating the conductor surface with functional materials such as insulation and protection using specific processes. For low-smoke halogen-free battery connection cables used in energy storage systems, this process requires forming a sheath layer that combines insulation, flame retardancy, and mechanical strength, directly affecting the cable's safety performance and service life. Currently, the industry mostly uses traditional semi-automatic sheathing methods, which have significant technical shortcomings.

[0003] Currently, traditional equipment generally relies on passive feeding structures when feeding cables for sheathing. The conductor release speed fluctuates with the weight of the reel, leading to conductor sheathing eccentricity. In addition, the conductor cannot be continuously cooled after sheathing, and the heat remaining on the sheathed conductor makes it difficult to wind it up, reducing cable sheathing efficiency. Therefore, to solve the above problems, we provide a fully automatic sheathing machine for low-smoke halogen-free battery connection cables for energy storage systems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic integrated machine for wrapping low-smoke halogen-free battery connecting cables for energy storage systems, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: An automatic integrated wrapping machine for low-smoke halogen-free battery connecting cables in an energy storage system includes a carrier plate. Two supports are fixedly mounted on the upper surface of the carrier plate. A wrapping mechanism is fixedly connected to one side of the two supports that are close to each other. A feeding mechanism and a receiving mechanism are fixedly mounted on the upper surface of the carrier plate. A support base is fixedly mounted on the upper surface of the support base. A lower mold is fixedly mounted on the upper surface of the lower mold. An upper mold is fixedly mounted on the upper surface of the carrier plate. Two support plates are fixedly mounted on the upper surface of the two support plates. A cooling water tank is fixedly connected to the upper surface of the cooling water tank. A cooler is fixedly mounted on the upper surface of the cooling water tank. The output end of the cooler passes through the cooling water tank and extends into the interior of the cooling water tank. A cooling water jacket is fixedly embedded in the inner wall of the cooling water tank.

[0006] Preferably, the feeding mechanism includes two support plates fixedly installed on the upper surface of the carrier plate. Bearings are fixedly embedded on the side of the two support plates that are close to each other. The inner rings of the two bearings are respectively fixedly connected to a drive shaft and a connecting shaft. A drive motor is fixedly installed on one side of one support plate. The output end of the drive motor is fixedly installed with one end of the drive shaft. A winding drum is installed on one end of the drive shaft and one end of the connecting shaft.

[0007] Preferably, the coating mechanism includes a material cylinder, the bottom end of which is fixedly connected to a discharge pipe, the bottom end of which is fixedly connected to the injection end of the upper mold, the outer surface of which is fixedly connected to an electric valve, and the upper surface of which is fixedly connected to an injection hopper.

[0008] Preferably, a liquid level observation plate is fixedly embedded on one side of the cooling water tank, and a liquid injection port is provided on the upper surface of the cooling water tank.

[0009] Preferably, a temperature sensor is fixedly installed on the inner top wall of the cooling water tank, and a controller is fixedly installed on one side of the bracket.

[0010] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: This energy storage system uses a fully automatic integrated coating machine for low-smoke halogen-free battery connecting cables. Through the drive motor of the feeding mechanism, the moving drive shaft drives the unwinding drum to release the conductor at a uniform speed, avoiding the problem of sudden tension changes caused by passive feeding. This allows the conductor to stably pass into the cavities of the lower and upper molds. The low-smoke halogen-free material is heated and melted by the material cylinder, and the discharge rate is controlled by an electric valve. The molten material is injected directionally into the mold injection end along the discharge pipe, and the conductor can be uniformly coated under the constraints of the upper and lower mold cavities. Compared with traditional manual material control, this solves the problems of eccentric coating and large thickness deviation, making it easier to automatically coat the conductor.

[0011] This energy storage system uses a fully automatic cable wrapping machine for low-smoke halogen-free batteries. The machine continuously cools the water in the cooling tank through a cooler, and in conjunction with a cooling water jacket, it enables the cooling water jacket to exchange heat with the conveyed wrapping layer. This allows the wrapping layer to cool and solidify quickly and evenly, solving the problems of slow cooling and poor shaping in traditional systems. As a result, it achieves automatic cable wrapping and improves the efficiency of cable wrapping. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-5 This utility model provides a technical solution for a fully automatic integrated wrapping machine for low-smoke halogen-free battery connecting cables used in energy storage systems: An automatic integrated wrapping machine for low-smoke halogen-free battery connecting cables in an energy storage system includes a carrier plate 1. Two supports 2 are fixedly mounted on the upper surface of the carrier plate 1. A wrapping mechanism 3 is fixedly connected to one side of the two supports 2 that are close to each other. A feeding mechanism 7 and a receiving mechanism 9 are fixedly mounted on the upper surface of the carrier plate 1. A support base 4 is fixedly mounted on the upper surface of the support base 4. A lower mold 5 is fixedly mounted on the upper surface of the lower mold 5. An upper mold 6 is fixedly mounted on the upper surface of the lower mold 5. Two support plates 11 are fixedly mounted on the upper surface of the carrier plate 1. A cooling water tank 12 is fixedly connected to the upper surface of the two support plates 11. A cooler 13 is fixedly mounted on the upper surface of the cooling water tank 12. The cooler 13 contains a compressor, evaporator, and condenser. The cooler operates through a refrigerant circulation phase change: the evaporator absorbs refrigerant from the cooling water tank 1. 2. The condenser discharges heat from the water, achieving continuous cooling of the water and providing a low-temperature medium for cooling and shaping. The output end of the cooler 13 passes through the cooling water tank 12 and extends into the interior of the cooling water tank 12. The inner wall of the cooling water tank 12 is fixedly embedded with a cooling water jacket 14. Specifically, the feeding mechanism 7 and the receiving mechanism 9 can respectively be responsible for feeding the conductor and winding the finished cable, forming a closed loop of material conveying for cable processing. The lower mold 5 and the upper mold 6 are combined to form a covering cavity, which can provide molding space for the molten material. The support plate 11 supports the cooling water tank 12, so that the cooling system and the mold and the receiving mechanism 9 form a reasonable distance to adapt to the cable conveying path. The cooling water tank 12 stores the cooling medium, the cooler 13 cools the cooling medium, and the cooling water jacket 14 enhances heat exchange by increasing the contact area.

[0017] In this embodiment, the feeding mechanism 7 includes two support plates 701 fixedly mounted on the upper surface of the carrier plate 1. Bearings 702 are fixedly embedded on the side of each support plate 701 that is close to each other. A drive shaft 705 and a connecting shaft 703 are respectively fixedly connected to the inner rings of the two bearings 702. A drive motor 706 is fixedly mounted on one side of one support plate 701. The output end of the drive motor 706 is fixedly mounted to one end of the drive shaft 705. A winding drum 704 is mounted on one end of the drive shaft 705 and one end of the connecting shaft 703. Specifically, the support plates 701 can support the feeding mechanism 7. Vertical support is provided, and the double plates are symmetrically arranged to bear the installation load of the drive shaft 705 and the connecting shaft 703. The bearing 702 reduces the frictional resistance when the drive shaft 705 and the connecting shaft 703 rotate. In addition, the connecting shaft 703 cooperates with the drive shaft 705 to jointly support the unwinding drum 704, so as to realize the coaxial rotation of the unwinding drum 704. The unwinding drum 704 is used to wind the conductor to be processed and is the carrier for conductor storage and release. The drive motor 706 is the active unwinding power source. By driving the drive shaft 705 to rotate, the release speed of the unwinding drum 704 is controlled, which solves the tension fluctuation problem of traditional passive unwinding.

[0018] In this embodiment, the coating mechanism 3 includes a material cylinder 301. A discharge pipe 303 is fixedly connected to the bottom end of the material cylinder 301. The bottom end of the discharge pipe 303 is fixedly connected to the injection end of the upper mold 6. An electric valve 304 is fixedly connected to the outer surface of the discharge pipe 303. A hopper 302 is fixedly connected to the upper surface of the material cylinder 301. A liquid level observation plate 16 is fixedly embedded on one side of the cooling water tank 12. An injection port 8 is opened on the upper surface of the cooling water tank 12. A temperature sensor 15 is fixedly installed on the inner top wall of the cooling water tank 12. A controller 10 is fixedly installed on one side of the support 2. Specifically, the material cylinder 301 of the coating mechanism 3 is used to contain and heat the low-smoke halogen-free material to achieve material... The material is melted, and the feeding hopper 302 provides a material supply channel for the material cylinder 301. The discharge pipe 303 guides the molten material to the mold. The electric valve 304 precisely controls the discharge amount to avoid errors caused by manual adjustment. The liquid level observation plate 16 of the cooling water tank 12 allows operators to intuitively view the remaining amount of cooling medium. The liquid injection port 8 is used to replenish the medium in a timely manner to ensure continuous cooling. The temperature sensor 15 monitors the temperature of the cooling medium in real time, providing data for the start-up and shutdown control of the refrigerator 13. The controller 10 receives signals from the temperature sensor 15 and other components, and coordinates the control of the speed of the drive motor 706, the opening degree of the electric valve 304, and the operation of the refrigerator 13 to achieve full-process automated coordination.

[0019] Working principle: When this device is running, the cable first passes through the inside of the conductor cavity formed by the combination of the lower mold (5) and the upper mold (6). After the cable is released from the unwinding drum (704) of the unwinding mechanism (7), it passes through the mold cavity along the straight path of "unwinding mechanism 7 → mold conductor inlet end → mold cavity", ensuring that the conductor and the cavity are coaxial and avoiding eccentric wrapping. At the same time, one end of the cable passes through the inside of the cooling water jacket 14 and the other end of the cable is wrapped around the outside of the take-up mechanism 9. At this time, the traction force for the cable to pass through and continuously convey comes from the coordinated drive of the take-up mechanism (9) and the unwinding mechanism (7). The motor drives the take-up drum to rotate to generate continuous traction force. The pulling force of the unloading mechanism (7) and the drive motor (706) of the unloading mechanism (7) adjust the release speed of the unloading drum (704) synchronously according to the winding speed of the winding mechanism 9, forming a coordinated traction of active unloading and active winding. At this time, the cable is wrapped inside the wrapping mechanism 3 and the wrapped cable enters the cooling water jacket 14. Then, the cold water inside the cooling water tank 12 is used to quickly cool the cable inside the cooling water jacket 14. Finally, the motor drives the winding drum to rotate to generate a continuous pulling force to wind the wrapped and cooled cable outside the winding mechanism 9. The above is the complete operation process of this device.
