Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and more specifically, it relates to a cable powder coating device. Background Technology

[0002] In the field of cable processing technology, in order to achieve the isolation and anti-sticking function of insulated wire cores, the industry usually coats the outer surface of the insulated wire cores with dry talc powder. The talc powder can play a key role in preventing the wire cores from sticking together as an isolation agent. The coating device generally includes a powder box containing talc powder. The cable wires to be coated are directly passed through one end of the powder box by the traction action of the extruder, and then passed out from the other end, so that a layer of talc powder is attached to the surface of the wires.

[0003] During talc coating, some talc powder is carried out of the powder box and scattered at the work site, resulting in waste. Traditional cable coating devices lack an effective collection and conveying mechanism to return the powder to the powder box, causing the recovered powder to be unusable in a timely manner. Therefore, there is an urgent need for a cable coating device with high recycling efficiency and the ability to automatically recycle powder to solve the problems of serious powder waste and poor recycling effect in existing technologies. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable powder coating device, which is achieved by the following specific technical means:

[0005] A cable coating device includes a powder box, a collection box fixedly installed at the rear end of the powder box, wire-passing holes one on both the front and rear surfaces of the powder box, wire-passing holes two on both the front and rear surfaces of the collection box, a conveying assembly inside the collection box, the conveying assembly including a cylinder and a connecting box, the cylinder being located inside the powder box, a rotating shaft one inside the cylinder, and a spiral blade one fixedly installed on the rotating shaft one;

[0006] The connecting box is inclined, and a discharge pipe is fixedly connected to the lower end of the connecting box. The discharge pipe is inserted into the powder box. The top end of the cylinder passes through the connecting box. A servo motor is fixedly installed on the connecting box, and the output shaft of the servo motor is fixedly connected to the rotating shaft.

[0007] Furthermore, the bottom surface of the inner wall of the collection box is designed to be inclined, and a powder collection plate is fixedly installed at the lower end of the inner wall, with the cylinder fixedly installed at the upper end of the powder collection plate.

[0008] Furthermore, a circular hole is provided on the upper surface of the powder collecting plate, the cylinder communicates with the inner cavity of the powder collecting plate through the circular hole, one bottom end of the rotating shaft is rotatably connected to the inner wall of the collecting box, and one bottom end of the spiral blade is inserted into the powder collecting plate.

[0009] Furthermore, the connecting box is fixedly installed on the upper end of the powder box.

[0010] Furthermore, two rotating shafts are rotatably installed inside the powder box. The two rotating shafts are located below the wire hole, and each of the two rotating shafts is fixedly equipped with a spiral blade.

[0011] Furthermore, gear 1 is fixedly installed on the ends of both rotating shafts 2, and the two gear 1 mesh with each other. A servo motor 2 is fixedly installed on the powder box, and the output shaft of the servo motor 2 is fixedly connected to the end of the rotating shaft 2.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The cable coating powder device has a collection box fixedly installed at the rear end of the powder box. The bottom surface of the inner wall of the collection box is designed with an inclination, which allows the talcum powder scattered when the cable passes through to slide naturally along the inclination bottom surface and eventually collect in the powder collection plate located on the lower inner wall of the collection box, thus completing the collection of powder. At the same time, the collection box is equipped with a conveying assembly consisting of a cylinder, a connecting box, a rotating shaft, a spiral blade, and a servo motor. The cylinder communicates with the inner cavity of the powder collection plate through a circular hole on the powder collection plate. The bottom end of the spiral blade is inserted into the powder collection plate. When the servo motor is started, it can drive the rotating shaft to rotate the spiral blade, conveying the talcum powder accumulated in the powder collection plate upward to the inclined connecting box. Then, it flows back to the powder box through the discharge pipe (inserted into the powder box) at the lower end of the connecting box. This "collection-conveying-returning" cycle structure can reuse the scattered talcum powder and reduce resource waste.

[0014] Second, when the servo motor 2 starts, it can drive the two rotating shafts 2 to rotate synchronously in opposite directions through the meshing transmission of gear 1. This causes the spiral blade 2 to stir the talc powder in the powder box. This structure can effectively break the accumulation and clumping of talc powder, ensuring that the powder box always maintains a loose and uniform powder state. This allows the surface of the cable to be stably coated with a uniform thickness of talc powder during the process of passing through, thus improving the powder coating quality.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a cable powder coating device, including a powder box 1, a collection box 2 fixedly installed at the rear end of the powder box 1, wire-passing holes 11 are opened on both the front and rear surfaces of the powder box 1, wire-passing holes 21 are opened on both the front and rear surfaces of the collection box 2, and a conveying component is provided inside the collection box 2. The conveying component includes a cylinder 3 and a connecting box 4. The cylinder 3 is located inside the powder box 1, and the collection box 2 is used to collect scattered talcum powder.

[0027] A rotating shaft 31 is provided inside the cylinder 3. A spiral blade 32 is fixedly installed on the rotating shaft 31. The connecting box 4 is inclined. A discharge pipe 41 is fixedly connected to the lower end of the connecting box 4. The discharge pipe 41 is inserted into the powder box 1. The top end of the cylinder 3 passes through the connecting box 4. A servo motor 6 is fixedly installed on the connecting box 4. The output shaft of the servo motor 6 is fixedly connected to the rotating shaft 31 and is used to drive the spiral blade 32 to rotate.

[0028] The bottom surface of the inner wall of the collection box 2 is inclined. A powder collection plate 5 is fixedly installed at the lower end of the inner wall. The cylinder 3 is fixedly installed on the upper end of the powder collection plate 5. The bottom surface of the inner wall of the collection box 2 is inclined. The fallen talcum powder will slide naturally along the inclined bottom surface and eventually be collected in the powder collection plate 5 at the lower end of the inner wall of the collection box 2.

[0029] A circular hole is provided on the upper surface of the powder collecting plate 5. The cylinder 3 communicates with the inner cavity of the powder collecting plate 5 through the circular hole. The bottom end of the rotating shaft 31 is rotatably connected to the inner wall of the collecting box 2. The bottom end of the spiral blade 32 is inserted into the powder collecting plate 5 for conveying the talc powder in the powder collecting plate 5.

[0030] The connecting box 4 is fixedly installed on the upper end of the powder box 1 to support and fix the connecting box 4;

[0031] Two rotating shafts 7 are rotatably installed inside the powder box 1. The two rotating shafts 7 are located below the cable passage hole 11. Helical blades 72 are fixedly installed on both rotating shafts 7. Gears 71 are fixedly installed on the shaft ends of both rotating shafts 7. The two gears 71 mesh with each other. A servo motor 8 is fixedly installed on the powder box 1. The output shaft of the servo motor 8 is fixedly connected to the shaft end of the rotating shaft 7. The rotating helical blades 72 will stir the talc powder in the powder box 1, break up the powder clumps, and keep the powder in the powder box 1 in a loose and uniform powder state, so that the surface of the cable can be stably coated with a uniform thickness of talc powder when the cable passes through.

[0032] The working principle of this embodiment:

[0033] Step 1: The cable to be coated is inserted into the powder box 1 through the cable passage hole 11 at the front end of the powder box 1 (the powder box 1 contains pre-stored talcum powder for coating). Under the action of an external traction device (such as an extruder), the cable exits through the cable passage hole 11 at the rear end of the powder box 1, and then continues to pass through the cable passage holes 21 on both sides of the collection box 2, finally completing the passage of the entire device. During this process, the surface of the cable will naturally adhere to the talcum powder in the powder box 1, achieving coating. The servo motor 8 fixed on the powder box 1 is started, and its output shaft directly drives a rotating shaft 7 connected to it to rotate. Each shaft of the second rotating shaft 7 is equipped with a gear 71, and the two gears 71 mesh with each other. Therefore, when one shaft of the second rotating shaft 7 rotates, it will drive the other shaft of the second rotating shaft 7 to rotate in the opposite direction synchronously through the gear meshing. Both shafts of the second rotating shaft 7 are fixed with spiral blades 72, and the entire shaft of the second rotating shaft 7 is located below the cable hole 11 (close to the cable passage path). The rotating spiral blades 72 will stir the talc powder in the powder box 1, break up the powder clumps, and keep the powder box 1 in a loose and uniform powder state, so that the surface of the cable can be stably coated with a uniform thickness of talc powder when the cable passes through.

[0034] Step 2: The bottom surface of the inner wall of the collection box 2 is designed with an incline. The fallen talcum powder will slide naturally along the inclined bottom surface and eventually collect in the powder collection plate 5 at the lower end of the inner wall of the collection box 2. The servo motor 6 fixed on the connecting box 4 is activated, and its output shaft drives the rotating shaft 31 to rotate (the rotating shaft 31 passes through the cylinder 3 and its bottom end is rotatably connected to the inner wall of the collection box 2); the spiral blade 32 on the rotating shaft 31 rotates synchronously with the rotating shaft, and the bottom end of the spiral blade 32 is inserted into the inner cavity of the powder collection plate 5 (collecting... The circular hole on the upper surface of the powder plate 5 allows the cylinder 3 to communicate with the inner cavity of the powder collecting plate 5. The rotating spiral blade 32 will transport the talc powder accumulated in the powder collecting plate 5 upward to the connecting box 4. The connecting box 4 is set at an inclination. The talc powder entering the connecting box 4 will flow naturally along the inclined surface to its lower end, and then be discharged back into the powder box 1 through the discharge pipe 41 at the lower end of the connecting box 4 (the discharge pipe 41 is inserted into the powder box 1), completing the powder cycle of "scattering-collection-transportation-returning" to avoid resource waste.
