Description

Technical Field

[0001] The present invention relates to the technical field of cable production equipment, and specifically to a cable talcum powder coating device. Background Art

[0002] During the production of sheathed cables, it is necessary to coat talcum powder on the cable core wires. There are two functions. First, during cable production, the talcum powder separates the cable core wires from the cable sheath, preventing the cable core wires from adhering to the cable sheath and facilitating cable stripping for use. Second, during cable use, it can reduce the friction between the cable sheath and the cable core wires and extend the service life of the cable core wires. Therefore, the coating of talcum powder is particularly important during production.

[0003] In the prior art, when coating talcum powder on cables, the cable is generally directly passed through the inside of a box storing talcum powder. For example, in the Chinese patent literature database, a cable talcum powder coating device with the application number 202222305655.2 is disclosed. Although plugs are generally provided at the wire passing openings on both sides of the box, a layer of talcum powder adheres to the surface of the cable, which is easily carried out to the outside of the box during movement, not only causing waste of materials but also potentially causing environmental pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide a cable talcum powder coating device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A cable talcum powder coating device includes a fixed outer shell and openings respectively provided on both sides of the fixed outer shell. A rotating cavity is rotatably arranged inside the fixed outer shell through a rotating drive mechanism. An inlet mechanism and an outlet mechanism are respectively arranged at both axial ends of the rotating cavity. The inlet mechanism includes a first fixed cavity fixed on one side of the fixed outer shell and a first movable cavity that is vertically movable inside the first fixed cavity through a lifting member. A first wire passing hole is penetrated through the first movable cavity, and a first material discharging port is arranged at the bottom end of the first movable cavity close to the fixed outer shell side. The outlet mechanism includes a second fixed cavity fixed on the other side of the fixed outer shell and a second movable cavity that is vertically movable inside the second fixed cavity. A second wire passing hole is penetrated through the second movable cavity, and a second material discharging port is arranged at the bottom end of the second movable cavity close to the fixed outer shell side. A reciprocating drive mechanism for pushing the second movable cavity to reciprocate vertically is arranged inside the second fixed cavity. When the second movable cavity moves to the topmost position, the second material discharging port is flush with the opening. When the second movable cavity moves to the lowermost position, the second wire passing hole is flush with the opening.

[0006] Further, a top cover is openably installed at the top end of the first movable cavity.

[0007] Further, two first guiding rollers are rotatably arranged on both sides of the first movable cavity close to the first wire hole, and the two first guiding rollers are respectively rotatably arranged at the upper and lower ends of the first wire hole, and cleaning layers are arranged on the outer sides of the first guiding rollers.

[0008] Further, a first material guiding plate is obliquely downward arranged at the bottom end of the first movable cavity, and the lower end of the first material guiding plate is located on the side close to the fixed outer shell.

[0009] Further, support rings are arranged on the outer side walls at both axial ends of the rotating cavity, and the support rings are rotatably arranged inside the fixed outer shell. The rotation driving mechanism includes a gear ring fixed on the outer side wall of the rotating cavity, a driving gear rotatably arranged below the gear ring, and a first rotation driving part for driving the driving gear to rotate, and the gear ring and the driving gear are meshed with each other.

[0013] Further, the reciprocating driving mechanism includes a cam rotatably installed inside the second fixed cavity through a rotating shaft and a second rotation driving part for driving the cam to rotate, and the cam is located below the second movable cavity.

[0014] Further, a roller is rotatably arranged at the bottom end of the second movable cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By arranging a feeding mechanism, a discharging mechanism and a reciprocating driving mechanism, the cable talcum powder coating device can prevent the talcum powder inside the rotating cavity from escaping to the outside through the opening, causing material waste and environmental pollution, and at the same time facilitating the recycling of the escaped talcum powder; By arranging a rotation driving mechanism, the rotating cavity can be driven to rotate inside the fixed outer shell, preventing the talcum powder from caking or the amount of talcum powder from decreasing, resulting in uneven powder coating on the cable.

[0020] Example 1, please refer to Figures 1-7 , an embodiment provided by the present invention: a cable talcum powder coating device, including a fixed outer shell 1 and openings 101 respectively arranged on both sides of the fixed outer shell 1. Specifically, the fixed outer shell 1 is a horizontally arranged cylindrical structure, and the opening 101 is a long strip opening, which is convenient for the cable to pass through and at the same time convenient for replenishing talcum powder inside.

[0021] A rotating cavity 2 is rotatably arranged inside the fixed outer shell 1 through a rotation driving mechanism 3. Refer to Figure 4, the rotating cavity 2 is a cylindrical structure coaxially arranged with the fixed outer shell 1, and circular through holes are provided through both ends thereof. The opening 101 is communicated with the inside of the rotating cavity 2. When the rotating cavity 2 rotates inside the fixed outer shell 1, talcum powder can be replenished into the rotating cavity 2 through the opening 101. Support rings 201 are arranged on the outer side walls at both axial ends of the rotating cavity 2, and the support rings 201 are rotatably arranged inside the fixed outer shell 1. Further, in order to reduce wear, balls or rollers can also be arranged on the outer side of the support rings 201 to make them in rolling connection with the fixed outer shell 1. The rotation driving mechanism 3 includes a gear ring 301 fixed on the outer side wall of the rotating cavity 2, a driving gear 302 rotatably arranged below the gear ring 301, and a first rotation driving member 303 for driving the driving gear 302 to rotate. The gear ring 301 and the driving gear 302 are meshed with each other. A base is horizontally fixed below the fixed outer shell 1. The first rotation driving member 303 can specifically be a motor, which is installed above the base through a bearing seat. A through hole for accommodating the driving gear 302 to extend into the fixed outer shell 1 is provided through the bottom end of the fixed outer shell 1. During operation, the driving gear 302 is driven to rotate by the first rotation driving member 303, and then the gear ring 301 and the rotating cavity 2 are driven to rotate slowly, further driving the talcum powder inside the rotating cavity 2 to turn over, avoiding caking, and enabling the talcum powder to be in full contact with the cable entering the inside. Further, the rotation driving mechanism 3 can also be set as a pulley mechanism, etc., as long as it can drive the rotating cavity 2 to rotate inside the fixed outer shell 1.

[0022] Further, a plurality of partition plates 202 are arranged on the inner side wall of the rotating cavity 2. The partition plates 202 are specifically plate-like structures parallel to the axis of the rotating cavity 2. The plurality of partition plates 202 are fixedly arranged on the inner side wall of the rotating cavity 2 in a circumferential array centered on the axis of the rotating cavity 2, and can scoop up the talcum powder falling to the bottom end, making the stirring more uniform.

[0023] Feeding mechanisms 4 and discharging mechanisms 5 are respectively arranged at both axial ends of the rotating cavity 2. Refer to Figure 3, the feeding mechanism 4 includes a first fixed cavity 401 fixed on one side of the fixed housing 1, and a first movable cavity 402 movably arranged up and down inside the first fixed cavity 401 through a lifting member 403. The first fixed cavity 401 is specifically a cuboid structure, and a through hole for accommodating the extension of the first movable cavity 402 to the outside is provided through its top end. The lifting member 403 can be specifically any one of a cylinder, an electric telescopic rod, etc., and is vertically installed inside the first fixed cavity 401 through a mounting plate, and its output end is fixedly connected to the bottom end of the first movable cavity 402, and drives the first movable cavity 402 to slide up and down inside the first fixed cavity 401 through its telescopic movement. A top cover 404 is openably installed at the top end of the first movable cavity 402, which is convenient for replenishing talcum powder into the first movable cavity 402. First wire holes 4021 are provided through the left and right sides of the first movable cavity 402. In this embodiment, the first wire holes 4021 are circular through holes. During normal operation, the first wire holes 4021 are located above the first fixed cavity 401, and the first wire holes 4021 are horizontally aligned with the opening 101. After the cable passes through the first movable cavity 402 through the first wire holes 4021, it then enters the rotating cavity 2 through the opening 101. Further, in order to prevent the talcum powder inside the rotating cavity 2 from entering the first movable cavity 402, a sponge block can be provided inside the first wire holes 4021 on the side close to the rotating cavity 2. An opening for accommodating the cable to pass through is provided in the middle of the sponge block. Two first guide rollers 405 are rotatably arranged on both sides of the first movable cavity 402 close to the first wire holes 4021, and the two first guide rollers 405 are respectively rotatably arranged at the upper and lower ends of the first wire holes 4021. Cleaning layers 4051 are provided on the outer sides of the first guide rollers 405. The cleaning layers 4051 can be specifically sponges or other flexible materials, and can wipe off dust and stains adhered to the surface when the cable passes through. A first discharge port 4022 is provided at the bottom end of the first movable cavity 402 close to the fixed housing 1. The first discharge port 4022 is located below the first wire holes 4021, and during normal wire routing, the first wire holes 4021 are received inside the first fixed cavity 401. When the talcum powder needs to be replenished inside the rotating cavity 2, the lifting member 403 extends and pushes until the first discharge port 4022 is flush with the opening 101. At this time, the first movable cavity 402 also moves to the topmost position, and the top cover 404 is opened to add talcum powder into the first movable cavity 402. A first guide plate 4023 is inclined downward at the bottom end of the first movable cavity 402, and the lower end of the first guide plate 4023 is located on the side close to the fixed housing 1. The talcum powder inside the first movable cavity 402 slides into the rotating cavity 2 under the action of gravity, and at the same time, the talcum powder escaping into the first movable cavity 402 during the powder coating process can also be recycled.

[0024] Refer to Figures 5-6, the discharging mechanism 5 includes a second fixed cavity 501 fixed on the other side of the fixed housing 1 and a second movable cavity 502 movably arranged up and down inside the second fixed cavity 501. A second wire passing hole 5021 for facilitating wire routing is provided through the second movable cavity 502. Similarly, a sponge block can also be arranged inside the second wire passing hole 5021 on the side close to the rotating cavity 2. Two second guide rollers 503 are rotatably arranged on both sides of the second movable cavity 502 close to the second wire passing hole 5021, and the two second guide rollers 503 are respectively rotatably arranged at the upper and lower ends of the second wire passing hole 5021. The second guide rollers 503 are in rolling connection with the cable, which can reduce the wear of the cable. A second material discharging port 5022 is arranged at the bottom end of the second movable cavity 502 close to the fixed housing 1. The second material discharging port 5022 is located below the second wire passing hole 5021. The bottom end of the second movable cavity 502 is inclined downwardly provided with a second material guiding plate 5023, and the lower end of the second material guiding plate 5023 is located on the side close to the fixed housing 1.

[0025] A reciprocating driving mechanism 6 for driving the second movable cavity 502 to reciprocate up and down is arranged inside the second fixed cavity 501. When the second movable cavity 502 moves to the topmost position, the second material discharging port 5022 is flush with the opening 101. When the second movable cavity 502 moves to the lowermost position, the second wire passing hole 5021 is flush with the opening 101. When the cable passes through the rotating cavity 2, a relatively large amount of talcum powder generally adheres to its surface. Inevitably, the talcum powder will be carried out during the movement of the cable. In the prior art, generally multiple relatively independent chambers are arranged for collection, but it is not convenient to recycle the collected talcum powder. In this embodiment, the reciprocating driving mechanism 6 includes a cam 601 rotatably installed inside the second fixed cavity 501 through a rotating shaft and a second rotating driving member 602 for driving the cam 601 to rotate. The cam 601 is located below the second movable cavity 502. The second rotating driving member 602 can specifically be a motor installed outside the second fixed cavity 501. Through its rotation, the cam 601 is driven to rotate. When the smooth section of the cam 601 rotates upward, the second movable cavity 502 abuts against the top of the cam 601 under the action of gravity. At this time, the second wire passing hole 5021 is flush with the opening 101 for facilitating wire routing. When the protruding section of the cam 601 rotates upward, the second movable cavity 502 is pushed upward. At this time, the bottom end of the second material discharging port 5022 moves to coincide with the opening 101, so that the talcum powder inside the second movable cavity 502 can slide into the rotating cavity 2 for recycling. At the same time, the second movable cavity 502 drives the cable to vibrate up and down, and the excess talcum powder can be shaken off.

[0026] A roller 603 is rotatably arranged at the bottom end of the second movable cavity 502. The roller 603 is located above the cam 601 and is in rolling connection with the cam 601, which can reduce wear.

[0027] Working principle: Before powder coating, the lifting member 403 extends to push the first movable cavity 402 upward. When the first material discharge port 4022 coincides with the opening 101, the top cover 404 is opened, and talcum powder is added into the first movable cavity 402. The talcum powder slides into the interior of the rotating cavity 2 under the guidance of the first guide plate 4023. During powder coating, the cable sequentially passes through the feeding mechanism 4, the rotating cavity 2, and the discharging mechanism 5. The cable first passes between the first guide rollers 405 to wipe off dust, stains, etc. adhering to the surface, and then enters the interior of the rotating cavity 2. The rotating cavity 2 is driven by the rotating drive mechanism 3 to rotate inside the fixed housing 1, causing the talcum powder to turn over inside to prevent caking or insufficient content to contact the cable. Finally, the cable enters the second movable cavity 502. The second rotating drive member 602 drives the cam 601 to rotate, and the roller 603 rolls along the outer wall of the cam 601, driving the second movable cavity 502 to move up and down continuously, thereby driving the cable to vibrate up and down to shake off the excess talcum powder to the top end of the second guide plate 5023. At the same time, when the second guide plate 5023 moves to the topmost end, the talcum powder passes through the second material discharge port 5022 and enters the interior of the rotating cavity 2 for recycling. When the work is completed, by extending the lifting member 403, the talcum powder entering the first movable cavity 402 can also be recycled.

[0028] Example 2, please refer to Figure 8 , on the basis of Example 1 in this embodiment, a reset mechanism 7 for pushing the second movable cavity 502 to reset downward is provided at the bottom end of the second movable cavity 502. The reset mechanism 7 includes a fixing plate 701 horizontally fixed inside the second fixed cavity 501, a guide rod 702 vertically fixed at the bottom end of the second fixed cavity 501, a reset spring 703 sleeved outside the guide rod 702, and a baffle 704 fixed at the bottom end of the guide rod 702. A through hole for the guide rod 702 to slide up and down is provided through the fixing plate 701. The top end of the reset spring 703 abuts against the fixing plate 701, and the bottom end of the reset spring 703 abuts against the baffle 704. The reset spring 703 pushes the second movable cavity 502 to reset downward to prevent the second movable cavity 502 from jamming and not closely fitting with the cam 601 when the cam 601 rotates upward.
