Description

Technical Field

[0001] The present invention relates to the technical field of power cables, and in particular to a device for quickly coating talcum powder on cables. Background Art

[0002] A cable is a power device for transmitting electrical energy or signals, usually composed of several or multiple groups of wires. The outside of the cable is wrapped with an insulating layer, so that each group of wires is isolated from each other through the insulating layer and works independently. When processing the cable, talcum powder needs to be coated on the surface of the cable to prevent the insulating layers from sticking to each other.

[0003] The existing cable talcum powder coating devices have the following technical defects when in use: Most traditional talcum powder coating methods directly penetrate the cable into the interior of the talcum powder. This method makes the talcum powder not well adsorbed on the surface of the cable, resulting in uneven coating of the talcum powder and affecting the processing quality. At the same time, when the cable penetrates into the interior of the talcum powder, since the talcum powder is easily bonded with water vapor to generate blocky condensation, it is extremely easy to cause obstruction of the cable transportation, seriously affecting the processing efficiency of the talcum powder. Summary of the Invention

[0027] Embodiment 1

[0028] Refer to Figures 1-5 , a rapid coating device for cable talcum powder, including a base 1. On the right side of the top of the base 1, two first support plates 2 are fixedly connected. On the adjacent sides of the two first support plates 2, two first pulleys 3 are rotatably connected. On the top of the base 1 and on one side of the two first support plates 2, four support columns 5 are fixedly connected. The height value of the adjacent support columns 5 close to the first support plate 2 is greater than the height value of the other side support columns 5. The tops of the four support columns 5 are fixedly connected with a cylinder body 6. The cylinder body 6 is inclined. Due to the inclined cylinder body 6, the talcum powder quickly slides down along the inside of the cylinder body 6 through the feed hopper 7. On the right side of the top of the base 1, two second support plates 9 are fixedly connected. On the adjacent sides of the two second support plates 9, a second pulley 10 is rotatably connected. On the side wall of the base 1 close to the second support plate 9, a connecting seat 11 is fixedly connected. On the top of the connecting seat 11, a third pulley 12 is provided. Through holes 8 are formed through the two side walls of the cylinder body 6. Inside the through holes 8, there is a cable body 4. One end of the cable body 4 passes through between the two first pulleys 3. The other end of the cable body 4 is successively sleeved on the second pulley 10 and the third pulley 12. The top of the cylinder body 6 is fixedly connected with a feed hopper 7. At the beginning, the talcum powder to be coated is added through the feed hopper 7. The talcum powder raw material continuously contacts the uniform feeding mechanism through the feed hopper 7. Inside the cylinder body 6 and below the feed hopper 7, there is a uniform feeding mechanism;

[0029] The uniform feeding mechanism includes a feeding cavity 61 opened inside the cylinder body 6. A vibration knocking mechanism is provided on one side of the discharging end of the feeding cavity 61 close to the conveying hole 8. A connecting disk 63 is fixedly connected to the back side of the inner wall of the feeding cavity 61 where a rotating shaft 62 is fixedly connected. A loading hopper 64 is fixedly connected to the outer side wall of the rotating shaft 62. When the material falls inside the feeding cavity 61, it falls into the inside of the loading hopper 64 under the action of its own gravity. With the continuous addition of the material along the feeding hopper 7, each loading hopper 64 is driven to rotate along the rotating shaft 62, so as to quantitatively feed the talcum powder to be coated, and the material is evenly scattered inside the feeding cavity 61. With the cable winding end driving the cable body 4 to continuously slide inside the conveying hole 8, the continuous conveying of the cable is realized. The loading hoppers 64 are arranged at equal intervals along the circumferential direction of the rotating shaft 62. Through the cooperation of the rotating shaft 62, the connecting disk 63 and the loading hopper 64, the talcum powder is evenly filled inside the loading hopper 64, and the continuous rotation of the connecting disk 63 further realizes the uniform quantitative packaging of the talcum powder raw material, achieving the effect of uniformly coating the talcum powder on the side wall surface of the cable and improving the processing quality. An inlet cutoff mechanism is provided inside the connecting disk 63.

[0030] Embodiment 2

[0031] As Figures 1-5 shown, this embodiment is basically the same as Embodiment 1. Preferably, the inlet cutoff mechanism includes a limiting cylinder 631 opened on the inner wall of the connecting disk 63. The limiting cylinders 631 are arranged at equal intervals along the circumferential direction of the connecting disk 63. An electromagnet 632 is fixedly installed on the inner wall of the limiting cylinder 631. The other end of the electromagnet 632 is fixedly connected to a first spring 633. The other end of the first spring 633 is fixedly connected to a movable rod 634. When the material is blocked due to excessive amount, it is necessary to cut off the feeding at this time. The inlet cutoff mechanism is activated, and the electromagnet 632 is driven to turn on. Under the electromagnetic repulsive force of the electromagnet 632, the movable rod 634 is driven to slide away from the electromagnet 632, so that the first spring 633 elongates, and thus the movable rod 634 slides into the rotating shaft 62. The timely opening of the conveying hole 81 when it is overly blocked is realized through the inlet cutoff mechanism. At the same time, the rotation of the rotating connecting disk 63 is prevented through the cooperation of the electromagnet 632, the movable rod 634, the first spring 633 and the limiting groove 621, and the material addition is stopped in time, so as to avoid the problem of talcum powder blockage and significantly improve the processing efficiency;

[0032] The feeding cutoff mechanism further includes a limiting groove 621 formed in the inner wall of the rotating shaft 62. The limiting grooves 621 are arranged at equal intervals along the circumferential direction of the rotating shaft 62, and are respectively arranged between adjacent material loading hoppers 64. As the movable rod 634 continues to slide, at this time, the rotating shaft 62 and the material loading hopper 64 continue to rotate. When it rotates to the position where the movable rod 634 is inserted into the limiting groove 621, the limiting is achieved. At this time, the material loading hopper 64 stops rotating, and the material no longer discharges along the uniform feeding mechanism. At this time, the falling speed of the talcum powder is significantly reduced, thus avoiding the accumulation and blockage caused by excessive material. The numerical value of the number of material loading hoppers 64 is the same as that of the limiting grooves 621 and the limiting cylinders 631. Each movable rod 634 arranged at equal intervals enters the limiting groove 621 to achieve stable cutoff and limiting. Here, the greater the current of the electromagnet 632, the faster the sliding speed of the movable rod 634, which indicates the cutoff speed of the current feeding cutoff mechanism. Therefore, the cutoff speed can be synchronously adjusted according to the detection result of the blockage detection mechanism.

[0033] Embodiment 3

[0034] As Figures 1-5 shown, this embodiment is basically the same as Embodiment 1. Preferably, the vibration knocking mechanism includes a limiting wheel 65 arranged on the inner bottom wall of the feeding cavity 61, and a movable wheel 66 is installed on the inner top wall of the feeding cavity 61. The cable body 4 penetrates and extends between the movable wheel 66 and the limiting wheel 65. During continuous conveying, the cable body 4 continuously contacts the movable wheel 66. Since the movable wheel 66 can shake, the movable wheel 66 shakes in contact along the direction perpendicular to the cable body 4 in the reverse direction, so that the talcum powder is coated on the surface of the cable body 4 faster. When the cable body 4 is conveyed along the conveying hole 8, the side wall of the cable body 4 is evenly coated with talcum powder. At the same time, through the cooperation of the limiting wheel 65, the movable wheel 66, and the limiting sleeve 660, the talcum powder blocked at the end of the feeding cavity 61 is effectively shaken and knocked, achieving the effect of timely vibration knocking on the blocked talcum powder and improving the processing efficiency. A blockage detection mechanism is arranged at the top of the movable wheel 66.

[0035] Embodiment 4

[0036] As Figures 1-5As shown, this embodiment is basically the same as Embodiment 1. Preferably, the blockage detection mechanism includes a connecting shaft 661 fixedly connected to the center of the movable wheel 66. A limiting sleeve 660 is fixedly connected to the top of the movable wheel 66 and at the bottom wall of the movable cavity 61. A second spring 663 is fixedly connected to the top of the connecting shaft 661. The top of the second spring 663 is fixedly connected to a piezoelectric ceramic 662. The other end of the piezoelectric ceramic 662 is fixedly connected to the inner top wall of the limiting sleeve 660. Two limiting blocks 664 are symmetrically and fixedly connected to the inner wall of the limiting sleeve 660. When the movable wheel 66 contacts the cable body 4 to generate a force, the movable wheel 66 moves upward, causing the second spring 663 to shake. As a result, an electric current is generated on the piezoelectric ceramic 662. When the piezoelectric current is larger, that is, the compression degree of the second spring 663 is larger, it means that the upward movement amplitude of the movable wheel 66 is larger, and there is more talcum powder at the bottom end of the blanking cavity 61. At this time, the feed cut-off mechanism needs to be opened in time to avoid continuous filling. Similarly, when the current on the piezoelectric ceramic 662 is smaller, the blockage situation is not obvious at this time. By keeping the current of the piezoelectric ceramic 662 and the current of the electromagnet 632 linearly increasing, the effective control of the feed amount can be achieved. The effective knocking of the talcum powder blocked at the end of the blanking cavity 61 is realized through the vibration knocking mechanism. At the same time, the real-time detection of the talcum powder blockage situation is realized through the cooperation setting among the connecting shaft 661, the piezoelectric ceramic 662, and the second spring 663. The feed is closed in time to avoid continuous blockage.

[0037] Embodiment Five

[0038] As Figures 1-5 shown, this embodiment is basically the same as Embodiment 1. Preferably, the movable rod 634 is made of a magnetic material, and the magnetism of the movable rod 634 is the same as that of the electromagnet 632, ensuring that the movable rod 634 slides into the inner part of the limiting groove 621 under the action of magnetic repulsion force to open the feed cut-off mechanism, thereby realizing feed cut-off. The piezoelectric ceramic 662 is electrically connected to the electromagnet 632, ensuring that the blockage detection mechanism transmits the electrical signal data of the piezoelectric ceramic 662 to the electromagnet 632, enabling the timely operation of the driving feed cut-off mechanism to prevent blockage caused by excessive materials.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
