Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing technology, and in particular to an automatic tension control device for wires and cables. Background Technology

[0002] Wires and cables are a large category of electrical products used for transmitting electrical energy, information, and electromagnetic energy conversion, and are widely used in various fields such as power, communications, transportation, and construction. They typically consist of a conductor, insulation layer, shielding layer, and protective layer. The conductor is the path for current transmission and is generally made of metals with good conductivity, such as copper and aluminum. The manufacturing process of wires and cables includes key steps such as conductor drawing, insulation extrusion, cabling, and sheath extrusion. In the insulation extrusion process, the insulating material wraps around the conductor. After the insulation layer is added, the wires and cables need to be placed in a water tank for cooling.

[0003] However, because the tension of the wires and cables is not controlled when they are in the water tank, they are not sufficiently cooled after the insulation is completed. The insulation layer is not tightly wrapped around the conductor. When subjected to greater tension, the wires and cables will be stretched and lifted off the water surface, affecting the cooling effect. Excessive tension also affects the quality of the insulated conductor. Utility Model Content

[0004] In view of this, the present invention proposes an automatic control device for the tension of electric wires and cables in order to solve the problems mentioned above.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An automatic tension control device for electric wires and cables includes a water tank, guide wheels, and a cable. The guide wheels are arranged opposite each other inside the water tank. The cable passes through both sides of the water tank and abuts against the guide wheels. A tension control mechanism is provided on the cable. The tension control mechanism includes a counterweight assembly, a support plate, a rotating shaft, and a tensioning wheel. The support plate is arranged opposite each other on the top surface of the counterweight assembly. The rotating shaft is located in the middle of the support plate. The tensioning wheel is rotatably mounted on the rotating shaft and is hung on the cable and located between the two guide wheels. Fixed plates are arranged opposite each other on both sides of the counterweight assembly. A sliding rod is arranged opposite each other at the bottom of the water tank. The sliding rod is slidably connected to the fixed plate.

[0007] Preferably, the counterweight assembly includes a counterweight block, an assembly rod, and a counterweight disc. The assembly rod is disposed opposite to the side of the counterweight block, and a plurality of counterweight discs are sleeved on the assembly rod. The counterweight discs are threadedly connected to the assembly rod.

[0008] Preferably, the system also includes a filter tank located on the side of the water tank. The bottom of the water tank and the filter tank are connected by a channel. A filter screen is installed in the channel. A water pump is installed on the bottom of the water tank. The water pump is connected to the water tank through a pumping pipe and to the filter tank through a return pipe. A one-way valve is installed on the return pipe.

[0009] Preferably, a purging mechanism is also included, which includes an air pump, an air pipe, and nozzles. The air pump is located at the top of the water tank, and the air pipe is U-shaped, with one end connected to the air pump and the other end located directly above the cable. The air pipe is provided with multiple air nozzles, which face the cable reel.

[0010] Preferably, the tensioning wheel is provided with an annular groove, and the cable abuts in the annular groove.

[0011] Preferably, a limiting mechanism is also included, which includes a support plate, a telescopic rod, a helical spring, and a limiting plate.

[0012] Preferably, the system also includes support legs, which are located on the bottom surface of the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A counterweight assembly is set up. The counterweight assembly forms a stable tension on the cable through the tension wheel. The sliding connection structure between the slide rod and the fixed plate ensures the vertical movement stability of the counterweight assembly, prevents tension deviation, and ensures that the cable is completely submerged in the cooling water. This solves the problem of insufficient cooling caused by the cable floating to the surface due to insufficient tension in the traditional process, which affects the quality of the insulation layer coating.

[0015] 2. A filter tank and a purging mechanism are installed. The purging mechanism uses directional air jets to dry the cable, blowing the water off the cable into the filter tank.

[0020] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] See Figures 1 to 2 This utility model provides an automatic tension control device for electric wires and cables, including a water tank 1, guide wheels 2, and a cable 12. The water tank 1 contains clean cooling water. The guide wheels 2 are arranged opposite each other in the water tank 1. The cable 12 passes through both sides of the water tank 1 and abuts against the guide wheels 2. A tension control mechanism is provided on the cable 12. The tension control mechanism includes a counterweight assembly, a support plate 5, a rotating shaft 6, and a tensioning wheel 7. The support plate 5 is arranged opposite each other on the top surface of the counterweight assembly. The rotating shaft 6 is located in the middle of the support plate 5. The tensioning wheel 7 is rotatably mounted on the rotating shaft 6 and is hung on the cable 12 and located between the two guide wheels 2. Fixed plates 4 are arranged opposite each other on both sides of the counterweight assembly. A sliding rod 3 is arranged opposite each other at the bottom of the water tank 1. The axis of the sliding rod 3 is perpendicular to the bottom surface of the water tank 1. The sliding rod 3 is slidably connected to the fixed plate 4. The fixed plate 4 and the sliding rod 3 cooperate to form a vertical guiding structure to ensure the vertical movement stability of the counterweight assembly and prevent tension deviation.

[0022] Specifically, when the control device is working, the cable 12 is first placed in the water tank 1, so that the cable 12 is placed on top of the two guide wheels 2. As the other device pulls the cable 12 (not shown in the figure), the counterweight component, under the action of gravity, forms a stable tension on the cable 12 through the tension wheel 7, forming a stable V-shaped immersion section. The counterweight component slides vertically along the slide bar 3 through the fixed plate 4 to avoid tension deviation. When the cable 12 experiences tension fluctuations due to changes in traction speed, the counterweight component adaptively raises and lowers, and adjusts the immersion depth of the cable 12 in real time through the tension wheel 7 to ensure uniform cooling of the insulation layer. This solves the problem in traditional processes where the cable 12 floats to the surface due to insufficient tension, resulting in insufficient cooling and affecting the quality of the insulation layer coating.

[0023] Preferably, the counterweight assembly includes a counterweight block 15, an assembly rod 13, and a counterweight disc 14. The assembly rod 13 is disposed opposite to the side of the counterweight block 15, and a plurality of counterweight discs 14 are sleeved on the assembly rod 13. The counterweight discs 14 are threadedly connected to the assembly rod 13.

[0024] When the tension needs to be adjusted, the tension can be adjusted by increasing or decreasing the number of counterweights 14. The mounting rod 13 is threaded to support the quick assembly and disassembly of the counterweights 15, thereby adapting to the tension requirements of different cables 12 and expanding the applicability of this device.

[0025] Preferably, a filter tank 20 is also included. The filter tank 20 is located on the side of the water tank 1. The bottom of the water tank 1 and the filter tank 20 are provided with interconnected channels. A filter screen 21 is provided in the channel. A water pump 24 is provided on the bottom surface of the water tank 1. The water pump 24 is connected to the water tank 1 through a water pumping pipe 22 and connected to the filter tank 20 through a water return pipe 25. A one-way valve 23 is provided on the water return pipe 25.

[0026] The filter tank 20 is equipped with a filter screen 21 for filtering the cooling water in the water tank 1. When the water pump 24 is started, the water pump 24 draws the cooling water out of the water tank 1 through the water pumping pipe 22 and flows into the filter tank 20 through the water return pipe 25. As the water level of the cooling water in the filter tank 20 rises, the water flows back into the water tank 1 after being filtered by the filter screen 21. The filter screen 21 intercepts impurities, realizing continuous purification of cooling water and preventing impurities from adhering to the cable 12 and affecting the quality of the insulation layer.

[0027] Preferably, a purging mechanism is also included, which includes an air pump 17, an air pipe 18, and a nozzle 19. The air pump 17 is located at the top of the water tank 1. The air pipe 18 is U-shaped, with one end connected to the air pump 17 and the other end located directly above the cable 12. The air pipe 18 is provided with multiple air nozzles, which face the cable reel.

[0028] As the cable 12 moves continuously, when it moves out of the water tank 1, water will adhere to the cable 12. The air pump 17 is then activated, and air is blown out at high speed through the air pipe 18 and nozzle 19 to blow away the water on the outer surface of the cable 12, thus drying and cleaning the cable 12. At the same time, the water is blown into the filter tank 20 below, which can recycle the cold cutting water and help maintain the water volume of the cold cutting water.

[0029] Preferably, the tensioning wheel 7 is provided with an annular groove 8, and the cable 12 abuts against the annular groove 8.

[0030] The cable 12 is embedded in the annular groove 8, and the contact pressure is evenly distributed, which effectively prevents the cable 12 from derailing and local stress concentration.

[0031] Preferably, a limiting mechanism is also included, which includes a support plate 16, a telescopic rod 10, a helical spring 9, and a limiting plate 11. The support plate 16 is located on the top surface of the water tank 1, the telescopic rod 10 is located on the bottom surface of the support plate 16, and its telescopic end is connected to the limiting plate 11. The helical spring 9 is sleeved on the telescopic rod 10, with one end connected to the support plate 16 and the other end connected to the limiting plate 11. The limiting plate 11 is located above the tensioning wheel 7.

[0032] The limiting mechanism is used to limit the tensioning wheel 7. In the wire and cable production line, when it is started, the tension increases instantly, and the cable 12 drives the tensioning wheel 7 to jump upward. The top of the tensioning wheel 7 will contact the limiting plate 11. When the limiting plate 11 moves upward, the telescopic rod 10 shortens, and the coil spring 9 is compressed to provide a reaction force and a buffering effect, so as to prevent the tensioning wheel 7 from flying off or causing abnormal misalignment, thereby affecting the normal use of the device.

[0033] Preferably, a support leg 26 is also included, which is disposed on the bottom surface of the water tank 1.

[0034] The support leg 26 is used to support the weight of the entire device. The support leg 26 has a certain height so that the water tank 1 can be kept horizontal and installed stably on different foundations.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
