Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a cable coating equipment for reducing the moisture content of cables. Background Art

[0002] The coating equipment for reducing the moisture content of cables is mainly applied in fields such as the power industry, the communication industry, and the manufacturing industry. In the power industry, this kind of equipment is used to produce high-voltage and extra-high-voltage cables to ensure their stability and safety during high-voltage transmission. In the communication industry, the coating equipment is used to produce communication cables with anti-interference and wear resistance to protect data transmission from the influence of the external environment. In the manufacturing industry, the equipment is used to produce various industrial cables to ensure the performance and lifespan of the cables even in complex and harsh working environments.

[0003] In the prior art, during the cable manufacturing process, the coating equipment plays a crucial role. It reduces the hollow parts in the cable by applying talcum powder on the surface of the bare cable. These hollow parts will cause a decrease in the moisture content of the cable when attaching the rubber layer subsequently, thus affecting the overall quality of the cable. However, in this process, it is difficult for the talcum powder to quickly and evenly collapse towards the cable after the cable passes through, which leads to uneven attachment of the hollow parts of the cable, and further makes the effect of reducing the water content limited. This uneven attachment not only affects the waterproof performance of the cable but may also cause local failures during the installation and use of the cable. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a cable coating equipment for reducing the moisture content of cables.

[0005] To achieve the above object, the utility model adopts the following technical solution: A cable coating device for reducing the water content of cables, including a talc bin, a hopper is fixed at the top of the talc bin, a vibrating table is fixed at the bottom of the talc bin, an installation bin is opened on one side of the vibrating table, an anti-collision groove is opened on the inner wall of the installation bin, a fixed seat is fixed at the bottom of the inner wall of the installation bin, a shaded-pole motor is fixed on the top of the fixed seat, a speed reducer is fixed at the output end of the shaded-pole motor, and a center-of-gravity eccentric wheel is fixed at the output end of the shaded-pole motor. In the prior art, during the cable manufacturing process, the coating device plays a crucial role. It reduces the hollow parts in the cable by applying talc powder on the surface of the bare cable. These hollow parts will cause a decrease in the water content of the cable when attaching the rubber layer subsequently, thus affecting the overall quality of the cable. However, during this process, it is difficult for the talc powder to quickly and evenly collapse towards the cable after the cable passes through, which leads to uneven attachment in the hollow parts of the cable, and further makes the water content reduction effect limited. This uneven attachment not only affects the waterproof performance of the cable but also may cause local failures during the installation and use of the cable. To solve such problems, the utility model adopts the method of installing a center-of-gravity eccentric wheel. When the cable passes through the talc powder inside the talc bin, the operator starts the shaded-pole motor to drive the center-of-gravity eccentric wheel to rotate. Due to the geometric characteristics of the center-of-gravity eccentric wheel, its center of mass and the rotation center are not at the same point, so a periodically changing centrifugal force will be generated. The magnitude and direction of this centrifugal force change continuously with the rotation of the center-of-gravity eccentric wheel, thereby causing the vibration of the entire device and making the talc bin vibrate accordingly. The talc powder collapses into the gaps where the cable takes away the talc powder under the vibration, making the talc powder evenly attach to the surface of the cable, achieving the effect of improving the yield rate.

[0006] Preferably, a shaft rotating column is rotatably connected to one side of the inner wall of the talc bin. The shaft rotating column is driven by a motor. Cutting grooves are circumferentially and arrayed on the circumferential surface of the shaft rotating column. A sliding arc-shaped member is slidably connected to the inner wall of the cutting groove. One end of the sliding arc-shaped member is fixed with a sleeve. The circumferential surface of the sleeve is fixed with a lever. In the prior art, workers need to put talcum powder into the talc bin through a hopper. Since talcum powder is a fine powder substance, there is a large frictional force and adhesion force between its particles, which makes it easy to form a bridging phenomenon in the hopper when passing through the hopper, resulting in poor feeding of talcum powder. Especially when the amount of talcum powder is large, this bridging phenomenon is more serious, causing the talcum powder to block in the hopper, not only hindering the smooth feeding of talcum powder, but also resulting in uneven distribution of talcum powder in the talc bin, leading to inconsistent thickness of the cable coating layer, affecting the appearance and performance of the cable. The lack or excess of talcum powder affects the adhesion and sealing performance of the rubber layer, thus reducing the waterproof and moisture-proof capabilities of the cable, resulting in a decrease in the product yield rate, increasing production costs and scrap rates. Workers have to frequently carry out manual intervention and treatment, which not only increases the labor intensity but also reduces the production efficiency. To solve such problems, the present utility model adopts the method of installing a lever, realizing that when the worker feeds the material, the motor is started to make the shaft rotating column engage the sleeve to drive the lever to rotate, breaking the bridging phenomenon between the talcum powders, preventing blockage, and achieving the effect of improving the yield rate.

[0007] Preferably, a bottom sunken square groove is opened at the bottom of the vibrating table. A top supporting rectangular plate is fixed to the inner wall of the bottom sunken square groove. A hollow outer frame is fixed to the bottom of the top supporting rectangular plate. A buffer spring is fixed to the bottom of the top supporting rectangular plate. A high-friction member is slidably connected to the inner wall of the hollow outer frame. A bottom plate is fixed to the bottom of the high-friction member. In the prior art, when the equipment works, the vibration causes a large amount of noise. Especially when it is set on the second floor and above, it will cause a large amount of noise to the lower floor, resulting in a poor working environment for workers and a reduced user experience. To solve such problems, the present utility model adopts the method of installing a hollow outer frame, realizing that when the equipment vibrates, it presses the top supporting rectangular plate to make the hollow outer frame descend to compress the buffer spring. The buffer spring absorbs the vibration and converts it into elastic potential energy. When the elastic potential energy is released, due to the large frictional force between the inner wall of the hollow outer frame and the side surface of the high-friction member, the friction converts the elastic potential energy into internal energy, thereby alleviating the influence brought by the vibration, reducing the equipment noise, and achieving the effect of improving the user experience.

[0008] Preferably, a bottom installation groove is opened at the bottom of the bottom plate. A trapezoidal rubber pad is fixed to the inner wall of the bottom installation groove. Anti-slip grooves are opened at the bottom of the trapezoidal rubber pad. The trapezoidal rubber pad reduces noise through its own characteristics, and at the same time, the anti-slip grooves prevent the equipment from slipping.

[0009] Preferably, an installation reinforcement plate is fixed to the side of the talc bin. The installation reinforcement plate is fixed to the vibrating table through bolts, improving the fixing effect between components, preventing detachment, and increasing the service life of the equipment.

[0010] Preferably, a diameter limiting member is fixed to the side of the talc bin to limit the diameter of the cable entering, remove particles above the surface, and improve the yield rate.

[0011] Preferably, an observation window is provided on the side of the talc bin to facilitate the staff to observe the situation of attached materials and improve the user experience.

[0012] Beneficial effects:

[0013] 1. In the prior art, during the cable manufacturing process, the coating equipment plays a crucial role. It reduces the hollow parts in the cable by applying talc powder on the surface of the bare cable. These hollow parts will cause a decrease in the water content rate of the cable when attaching the rubber layer subsequently, thus affecting the overall quality of the cable. However, in this process, it is difficult for the talc powder to quickly and evenly collapse towards the cable after the cable passes through, resulting in uneven attachment of the hollow parts of the cable, and then the effect of reducing the water content is limited. This uneven attachment not only affects the waterproof performance of the cable but also may cause local failures during the installation and use of the cable. To solve such problems, the present utility model adopts the method of installing a center-of-gravity eccentric wheel. When the cable passes through the talc powder inside the talc bin, the staff starts the shaded-pole motor to drive the center-of-gravity eccentric wheel to rotate. Due to the geometric characteristics of the center-of-gravity eccentric wheel, its center of mass and the rotation center are not at the same point, so a periodically changing centrifugal force will be generated. The magnitude and direction of this centrifugal force change continuously with the rotation of the center-of-gravity eccentric wheel, thereby causing the vibration of the entire device, making the talc bin vibrate accordingly. The talc powder collapses into the gaps where the talc powder is taken away by the cable under the vibration, so that the talc powder is evenly attached to the surface of the cable, achieving the effect of improving the yield rate.

[0014] 2. In the prior art, workers need to put talcum powder into the talc bin through a hopper. Since talcum powder is a fine powder substance, there is a large frictional force and adhesion force between its particles, which makes it easy to form a bridging phenomenon in the hopper when passing through the hopper, resulting in poor feeding of talcum powder. Especially when the amount of talcum powder is large, this bridging phenomenon is more serious, causing blockage of talcum powder in the hopper, not only hindering the smooth feeding of talcum powder, but also resulting in uneven distribution of talcum powder in the talc bin, leading to uneven thickness of the cable coating layer, affecting the appearance and performance of the cable. The lack or excess of talcum powder affects the adhesion and sealing performance of the rubber layer, thus reducing the waterproof and moisture-proof ability of the cable, resulting in a decrease in the product yield, an increase in production costs and scrap rates. Workers have to frequently carry out manual intervention and treatment, which not only increases the labor intensity, but also reduces the production efficiency. To solve such problems, the present utility model adopts the method of installing a lever, so that when the worker feeds the material, the motor is started to make the shaft rotating column engage with the sleeve to drive the lever to rotate, breaking the bridging phenomenon between talcum powders, preventing blockage, and achieving the effect of improving the product yield.

[0015] 3. In the prior art, when the equipment works, the vibration causes a relatively large noise. Especially when it is set on the second floor and above, it will cause a relatively large noise to the lower floor, resulting in a poor working environment for workers and a reduced user experience. To solve such problems, the present utility model adopts the method of installing a hollow outer frame, so that when the equipment vibrates, it presses the top bearing moment plate to make the hollow outer frame descend to compress the buffer spring. The buffer spring absorbs the vibration and converts it into elastic potential energy. When the elastic potential energy is released, due to the large frictional force between the inner wall of the hollow outer frame and the side surface of the high-friction part, the friction converts the elastic potential energy into internal energy, thereby alleviating the influence brought by the vibration, reducing the equipment noise, and achieving the effect of improving the user experience.

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present utility model.

[0025] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Specific embodiment:

[0027] Refer to Figures 1-6, a cable coating device for reducing the moisture content of cables, including a talc bin 101, a hopper 102 is fixed at the top of the talc bin 101, a vibrating table 1 is fixed at the bottom of the talc bin 101, an installation bin 2 is opened on one side of the vibrating table 1, an anti-collision groove 201 is opened on the inner wall of the installation bin 2, a fixed seat 202 is fixed at the bottom of the inner wall of the installation bin 2, a shaded-pole motor 203 is fixed at the top of the fixed seat 202, a speed reducer 204 is fixed at the output end of the shaded-pole motor 203, a center-of-gravity eccentric wheel 205 is fixed at the output end of the shaded-pole motor 203. During the cable manufacturing process, the coating device plays a crucial role. It reduces the hollow parts in the cable by applying talc powder on the surface of the bare cable. These hollow parts will cause a decrease in the moisture content of the cable when attaching the rubber layer subsequently, thus affecting the overall quality of the cable. However, during this process, it is difficult for the talc powder to quickly and evenly collapse towards the cable after the cable passes through, which leads to uneven attachment in the hollow parts of the cable, and then the effect of reducing the water content is limited. This uneven attachment not only affects the waterproof performance of the cable but may also cause local failures during the installation and use of the cable. It is solved by adopting the method of installing the center-of-gravity eccentric wheel 205. When the cable passes through the talc powder inside the talc bin 101, the staff starts the shaded-pole motor 203 to drive the center-of-gravity eccentric wheel 205 to rotate. Due to the geometric characteristics of the center-of-gravity eccentric wheel 205, its center of mass and the center of rotation are not at the same point, so a periodically changing centrifugal force will be generated. The magnitude and direction of this centrifugal force change continuously with the rotation of the center-of-gravity eccentric wheel 205, thus causing the vibration of the entire device, making the talc bin 101 vibrate accordingly. The talc powder collapses towards the voids where the cable takes away the talc powder under the vibration, making the talc powder evenly attach to the surface of the cable, achieving the effect of improving the yield. An installation reinforcement plate 5 is fixed on the side of the talc bin 101, and the installation reinforcement plate 5 is fixed to the vibrating table 1 through bolts to improve the fixing effect between components, prevent detachment, and improve the service life of the device. A diameter-limiting part 501 is fixed on the side of the talc bin 101 to limit the diameter of the cable entering, remove the particles higher than the surface, and improve the yield. An observation window 502 is provided on the side of the talc bin 101, which is convenient for the staff to observe the material attachment situation and improve the user experience.

[0028] On one side of the inner wall of the talc bin 101, a rotating column 301 is rotatably connected. The rotating column 301 is driven by a motor. On the circumferential surface of the rotating column 301, cutting grooves 302 are arranged in a circumferential array. A sliding arc-shaped member 303 is slidably connected to the inner wall of the cutting groove 302. One end of the sliding arc-shaped member 303 is fixed with a sleeve 3. On the circumferential surface of the sleeve 3, a dial rod 304 is fixed. Workers need to put talcum powder into the talc bin 101 through the hopper 102. Since talcum powder is a fine powder substance, there is a large frictional force and adhesive force between its particles, which makes it easy to form a bridging phenomenon in the hopper 102 when passing through the hopper 102, resulting in poor feeding of the talcum powder. Especially when the amount of talcum powder is large, this bridging phenomenon is more serious, causing the talcum powder to be blocked in the hopper 102, which not only hinders the smooth feeding of the talcum powder, but also leads to uneven distribution of the talcum powder in the talc bin 101, resulting in uneven thickness of the cable coating layer, affecting the appearance and performance of the cable. The lack or excess of talcum powder affects the adhesion and sealing performance of the rubber layer, thus reducing the waterproof and moisture-proof ability of the cable, resulting in a decrease in the product yield rate, an increase in production costs and scrap rates. Workers have to frequently carry out manual intervention and treatment, which not only increases the labor intensity, but also reduces the production efficiency. It is solved by installing the dial rod 304. When the worker feeds the material, the motor is started to make the rotating column 301 engage the sleeve 3 to drive the dial rod 304 to rotate, breaking the bridging phenomenon between the talcum powders, preventing blockage, and achieving the effect of improving the yield rate. At the bottom of the vibrating table 1, a bottom sunken square groove 4 is opened. On the inner wall of the bottom sunken square groove 4, a top supporting rectangular plate 401 is fixed. At the bottom of the top supporting rectangular plate 401, a hollow outer frame 402 is fixed. At the bottom of the top supporting rectangular plate 401, a buffer spring 403 is fixed. A high-friction member 404 is slidably connected to the inner wall of the hollow outer frame 402. At the bottom of the high-friction member 404, a bottom plate 405 is fixed. When the equipment works, the vibration causes a large amount of noise. Especially when it is set on the second floor and above, it will cause a large amount of noise to the lower floor, resulting in a poor working environment for workers and a reduction in the user experience. It is solved by installing the hollow outer frame 402. When the equipment vibrates, it presses the top supporting rectangular plate 401 to make the hollow outer frame 402 descend to compress the buffer spring 403. The buffer spring 403 absorbs the vibration and converts it into elastic potential energy. When the elastic potential energy is released, due to the large frictional force between the inner wall of the hollow outer frame 402 and the side surface of the high-friction member 404, the friction converts the elastic potential energy into internal energy, thereby alleviating the influence brought by the vibration, reducing the equipment noise, and achieving the effect of improving the user experience. At the bottom of the bottom plate 405, a bottom installation groove 406 is opened. On the inner wall of the bottom installation groove 406, a trapezoidal rubber pad 407 is fixed. On the bottom of the trapezoidal rubber pad 407, an anti-slip groove 408 is opened. The trapezoidal rubber pad 407 reduces the noise through its own characteristics, and at the same time the anti-slip groove 408 prevents the equipment from slipping.

[0029] Working principle of the utility model: When the cable passes through the talcum powder inside the talcum bin 101, the staff starts the shaded-pole motor 203 to drive the center-of-gravity eccentric wheel 205 to rotate. Due to the geometric characteristics of the center-of-gravity eccentric wheel 205 driven, its center of mass and the rotation center are not at the same point, so a periodically changing centrifugal force will be generated. The magnitude and direction of this centrifugal force change continuously with the rotation of the center-of-gravity eccentric wheel 205, thereby causing the vibration of the entire device, making the talcum bin 101 vibrate accordingly. The talcum powder collapses into the gaps where the talcum powder is taken away by the cable under vibration, so that the talcum powder is evenly attached to the surface of the cable. When the staff feeds the material, the motor is started to make the shaft rotating column 301 engage with the sleeve 3 to drive the lever 304 to rotate, breaking the bridging phenomenon between the talcum powders to prevent blockage.
