Description

Technical Field

[0001] The invention relates to the technical field of cable production and processing, and in particular to a cable drying device for cable production. Background Art

[0002] Cables are generally used in power transmission and communication systems. They are usually composed of conductor metal, cable insulation layer and cable sheath layer. In order to protect the cable conductor metal and cable insulation layer from the external environment, a cable sheath layer is usually wrapped on the outside of the cable insulation layer. The cable sheath layer is generally made of polyvinyl chloride, polyethylene nylon and other materials. Since the cable sheath layer may need to be immersed in water to cool down after wrapping, there may be moisture inside the cable sheath layer. The presence of moisture will affect the subsequent use of the cable, so the cable sheath layer needs to be dried after the cable sheath layer is wrapped around the cable.

[0003] The current existing drying method is to put the cable into a drying chamber and use a hot air blower to blow hot air directly to dry the cable, and the temperature in the drying chamber is constant. Due to the uneven distribution of moisture on the cable, this drying method easily causes the cable to be incompletely dried.

[0004] For example, CN116313321B involves a cable drying device for cable production, which includes a base, a fixed shell fixedly connected to the base, a drying cylinder fixedly connected to a fixed disk, a rotating disk provided on the fixed disk, an annular shell provided on the drying cylinder, a fixed square tube fixedly connected to the annular shell, a sliding square tube provided on the fixed square tube, a first rotating shaft fixedly connected to the sliding square tube, and a special-shaped wind plate rotatably connected to the first rotating shaft. The drying device dries the cable by graded drying, and at the same time, the circulation speed of the gas on the cable surface is increased by the rotation of the special-shaped wind plate, so as to further accelerate the evaporation speed of the water on the cable surface. The graded drying method increases the drying process, prolongs the drying time, and reduces the production efficiency. Moreover, for the liquid unevenly attached to the cable surface, simple drying is not thorough; in addition, the drying device can only dry one cable at a time. In order to improve the drying efficiency of the cable body and remove the water attached to the cable body surface during the drying process, it is urgent to design a drying device for cable production.

[0035] Example

[0036] like Figures 1 to 7 As shown, the present invention provides a cable drying device for cable production, including a drying shell 200 fixedly installed by a base 100, a drying chamber 210 is formed inside the drying shell 200, and a hot air mechanism 400 is installed outside the drying shell 200, and the hot air mechanism 400 is connected to the drying chamber 210, and hot air is supplied to the drying chamber 210 through the hot air mechanism 400 to realize the drying operation of the cable.

[0037] Preferably, the hot air mechanism 400 includes an external hot air supply source, an air inlet pipe 410 and a collecting chamber 420. The collecting chamber 420 is installed on the drying shell 200, but the collecting chamber 420 does not cover the entire periphery of the drying shell 200. A certain space needs to be reserved at the lower part of the drying shell 200 for setting the drainage structure. Therefore, a detachable drainage box 260 is provided at the bottom of the drying shell 200. The drainage box 260 is installed at the bottom of the drying shell 200 in an inclined manner and forms an angle less than 90° with the axis of the drying shell 200.

[0038] In some preferred embodiments, the collecting chamber 420 is connected with the drying chamber 210, and the air inlet pipe 410 connects the external hot air supply source with the collecting chamber 420. Further, the drying shell 200 is cylindrical as a whole, and a plurality of rotating air guide plates 230 are arranged on the inner wall of the drying shell 200, and the rotating directions formed by each rotating air guide plate 230 are the same, and an air inlet 240 with the same rotating direction as the rotating air guide plate 230 is arranged between each two adjacent rotating air guide plates 230, and the air inlet 240 connects the collecting chamber 420 with the drying chamber 210. By providing the rotating air guide plates 230 and the air inlet 240 with the same rotating direction, the hot air input from the external hot air supply source through the air inlet pipe 410 forms a rotating vortex around the axis of the drying shell 200 in the drying chamber 210, further increasing the chance of hot air contacting the cable, and also increasing the flow rate of hot air in the chamber, thereby improving the drying efficiency.

[0039] Preferably, the drying housing 200 is provided with a plurality of cable inlets 220 extending through the axial direction thereof. In this embodiment, five cable inlets 220 are provided, and more cable inlets 220 may be provided in reality. Specifically, one of the cable inlets 220 is provided at the center of the drying housing 200, and the remaining cable inlets 220 are provided at equal intervals around the central inlet on the drying housing 200.

[0040] Preferably, a cable moisture removal mechanism 300 is further provided in the drying chamber 210, and the cable moisture removal mechanism 300 includes a driving motor 310, a connecting belt 320, a driving part 330 and a moisture adsorption part 340. The driving motor 310 is installed on the base 100, and the driving part 330 is rotatably installed at the cable inlet 220. The moisture adsorption part 340 is installed on the driving part 330 and is located in the drying chamber 210. The output end of the driving motor 310 is connected to the driving part 330 through the connecting belt 320. Under the drive of the driving motor 310, the driving part 330 rotates to drive the moisture adsorption part 340 to absorb moisture on the cable. At the same time, since the cable is in a feeding state, that is, the cable moves along the axial direction of the drying shell 200, the moisture adsorption part 340 can sequentially and completely remove the uneven liquid attached to the surface of the cable.

[0041] In some preferred embodiments, the driving part 330 includes a mounting sleeve 331, a center driving gear 332, a driven gear 333, a driving pulley 334 and a driven pulley 335. The center driving gear 332 and the driven gear 333 are both provided with the mounting sleeve 331. The mounting sleeve 331 is rotatably mounted on the cable inlet 220. The driven pulley 335 is mounted on the center driving gear 332. The driving pulley 334 is mounted on the driving motor 310. The connecting belt 320 is sleeved on the driving pulley 334 and the driven pulley 335 to transmit the power output by the driving motor 310 to the center driving gear 332. The center driving gear 332 is meshed and connected with the driven gear 333, and the driven gear 333 is driven to rotate synchronously through the center driving gear 332.

[0042] In some preferred embodiments, the drying shell 200 is provided with a protective shell 336 on one end of the driving part 330, and the driving part 330 is located between the protective shell 336 and the drying shell 200, that is, the protective shell 336 is buckled and installed on the drying shell 200, and the driving part 330 is covered inside, in order to ensure aesthetics while preventing foreign matter from being entangled in the driving part 330 and affecting its rotation.

[0043] In some preferred embodiments, the mounting sleeve 331 is evenly distributed with a plurality of mounting holes on its circumference, the moisture adsorption part 340 includes a plurality of mounting plates 341, a spring 342, a ball groove 343 and a drying ball 344, the drying ball 344 can realize universal rotation in the ball groove 343, the ball groove 343 is evenly distributed on the mounting plate 341, the mounting plate 341 is connected and installed on the mounting sleeve 331 through the spring 342, the spring 342 is installed in the mounting hole, in the initial state, the caliber surrounded by the plurality of mounting plates 341 is smaller than the cable diameter, when the cable passes through, the diameter of the cable opens the mounting plate 341 so that the drying ball 344 can fully contact the cable, and this structural design has another advantage that it can be applied to the drying operation of cables of different specifications and diameters. It is worth mentioning that the drying ball 344 is pressed by a desiccant, and the desiccant can be reused after being dried again. Therefore, an infrared heating tube is also provided in the drying chamber 210. When the cable is dried (ie, there is no cable inside the drying device), the infrared heating tube can be turned on to dry the drying ball 344 to ensure the normal use of the drying ball 344 next time.

[0044] In summary, the cable drying device for cable production provided by the present invention is provided with a cable moisture removal mechanism to achieve the removal of residual and uneven moisture attached to the cable first. At the same time, the moisture removal mechanism can also be applied to the drying operation of cables of different specifications and diameters. The installation plate is opened by the inserted cable, and then tightened by the action of the spring elastic force to ensure that the drying ball fully contacts the cable. As the cable gradually advances, the moisture attached to the cable is fully removed. The cable drying device drives the driving part to rotate through the driving motor. At the same time, since the cable is in the state of feeding, that is, the cable advances along the axial direction of the drying shell, the moisture adsorption part can sequentially and completely remove the uneven liquid attached to the surface of the cable. A plurality of air guide plates with the same rotation direction and an air inlet with the same rotation direction as the air guide plates are arranged in the drying chamber of the drying device, so that the input hot air can form a vortex in the drying chamber, increase the wind speed, accelerate the drying rate, ensure that the hot air is fully in contact with the cable, and further prolong the effect of the hot air on the cable. The drainage box in the cable drying device provided by the present invention forms an acute angle with the axis of the drying shell to facilitate water drainage. At the same time, the drainage direction of the drainage box is not in the tangential direction of the hot air rotation direction, avoiding a large amount of hot air escaping from the drainage port.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
