[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-8 A powder coating device for fireproof cable production includes a powder coating mechanism 1 and a cleaning mechanism 2. The powder coating mechanism 1 consists of a support leg 11, a tank body 12 and a plurality of nozzles 13. The support leg 11 is connected to the bottom end of the tank body 12. Both ends of the tank body 12 are closed and have through holes 14. The plurality of nozzles 13 are evenly distributed on the inner wall of the tank body 12 in a circular shape. The cleaning mechanism 2 is rotatably connected to one end of the powder coating mechanism 1. The cleaning mechanism 2 consists of a motor 21, a transmission gear 22, an outer gear ring 23, a first cylinder 24, a first connecting shaft 25, a first bevel gear 26, a square shaft 27, a sliding pipe 28 and a cleaning head 29. A linkage mechanism 3 is arranged between the cleaning mechanism 2 and the powder coating mechanism 1. The linkage mechanism 3 consists of an inner gear ring 31, a driven gear 32, a fixed gear 33, a sleeve 34, a second connecting shaft 35 and a second bevel gear 36.

[0029] Reference Figure 3 and Figure 6 In this embodiment, the motor 21 is arranged on the tank body 12, the transmission gear 22 is connected to the output end of the motor 21, the outer gear ring 23 is connected to the first cylinder 24 and meshes with the transmission gear 22, one end of the first connecting shaft 25 is rotatably connected to the side wall of the first cylinder 24, the first bevel gear 26 is connected to the other end of the first connecting shaft 25, the square shaft 27 is connected to the first bevel gear 26, the sliding tube 28 is slidably connected to the square shaft 27, and the cleaning head 29 is connected to the sliding tube 28.

[0030] Reference Figure 4 and Figure 6-7 In this embodiment, the inner gear ring 31 is connected to the first cylinder 24, the fixed gear 33 is connected to the powder coating mechanism 1, the driven gear 32 is meshed between the inner gear ring 31 and the fixed gear 33, the driven gear 32, the second connecting shaft 35 and the second bevel gear 36 are connected, the sleeve 34 is sleeved on the second connecting shaft 35 and the second bevel gear 36, the second bevel gear 36 is meshed with the first bevel gear 26, and one end of the first connecting shaft 25 is rotatably connected in the sleeve 34.

[0031] Working principle: the motor 21 drives the transmission gear 22 to rotate, and the transmission gear 22 meshes with the outer gear ring 23, so that the first cylinder 24 generates a circular motion. Since the first connecting shaft 25 is rotatably connected to the side wall of the first cylinder 24, the first connecting shaft 25 follows the first cylinder 24 to generate a circular motion. Through the connection of the first bevel gear 26, the square shaft 27 and the sliding tube 28, the cleaning head 29 follows the first cylinder 24 to perform a circular motion. At the same time, the circular motion of the first cylinder 24 drives the inner gear ring 31 to rotate. Since the fixed gear 33 is connected to the tank body 12 and is in a relatively static state, the driven gear 32 is driven by the inner gear ring 31 to rotate on the fixed gear 33 in a circular motion. Since the sleeve 34 is rotatably connected to the second connecting shaft 35 and is affected by the penetration of the first connecting shaft 25, the sleeve 34 No rotation is generated. The relative second connecting shaft 35, driven by the driven gear 32, causes the second bevel gear 36 to rotate. Through the meshing of the first bevel gear 26, the square shaft 27 drives the slide tube 28 to rotate, and the slide tube 28 drives the cleaning head 29 to rotate, so that the friction between the cleaning head 29 and the surface of the fireproof cable becomes larger, thereby improving the cleanliness of the surface of the fireproof cable and generating static electricity on the surface of the fireproof cable. After cleaning, the fireproof cable enters the powder coating mechanism 1 and passes through the perforation 14 on one side into the tank body 12. The circumferentially distributed nozzles 13 allow the powder to be sprayed on the surface of the fireproof cable in all directions. The electrostatic effect enhanced by the cooperation between the cleaning mechanism 2 and the linkage mechanism 3 greatly improves the adhesion of the powder on the fireproof cable. The powder-coated fireproof cable is pulled out from the perforation 14 on the other side by a traction device.

[0032] Reference Figure 2 and Figure 6 In this embodiment, the linkage mechanism 3 also includes an annular groove 37 and a positioning shaft 38. The annular groove 37 is provided on one end of the tank body 12. The single-side cross section of the annular groove 37 is T-shaped. The positioning shaft 38 is connected to the driven gear 32. The cross section of the positioning shaft 38 is T-shaped. The positioning shaft 38 is movably connected in the annular groove 37 to provide a positioning effect for the self-rotation of the circular motion of the driven gear 32, prevent the driven gear 32 from shaking, and improve the stability of the meshing transmission between the driven gear 32, the inner gear ring 31 and the fixed gear 33.

[0033] Reference Figure 6 In this embodiment, the first cylinder 24 is embedded in one end of the tank body 12, and the outer wall of one end of the embedded part is radially extended, ensuring that the first cylinder 24 rotates on one end of the tank body 12 while preventing separation to improve the connection effect.

[0034] Reference Figure 1 , Figure 5-6 and Figure 8In this embodiment, an adjustment mechanism 4 is provided on the end of the first cylinder 24 away from the tank body 12. The adjustment mechanism 4 is composed of an electric telescopic rod 41, a second cylinder 42, a connecting rod 43 and a ring 44. The electric telescopic rod 41 is connected between the second cylinder 42 and the first cylinder 24. The ring 44 is sleeved on the cleaning head 29. One end of the connecting rod 43 is rotatably connected to the ring 44, and the other end is rotatably connected to the inner wall of the second cylinder 42.

[0035] Working principle: When the outer diameter of the fireproof cable changes, the distance between the second cylinder 42 and the first cylinder 24 can be changed by driving the electric telescopic rod 41. Through the rotation connection of the connecting rod 43 and the guiding effect formed between the square shaft 27 and the sliding tube 28, the ring 44 drives the cleaning head 29 to move, and the sliding tube 28 follows the cleaning head 29 to move on the square shaft 27. In addition, the connection between the ring 44 and the cleaning head 29 does not hinder the self-rotation effect of the cleaning head 29.

[0036] Reference Figure 6-8 In this embodiment, the adjustment mechanism 4 also includes a spring 45, which is arranged in the slide tube 28. One end of the spring 45 is connected to the square shaft 27, and the other end is connected to the cleaning head 29. When the electric telescopic rod 41 is retracted to drive the second cylinder 42 to approach the first cylinder 24, the inclined direction of the connecting rod 43 enables the collar 44 to smoothly drive the cleaning head 29 to move in the direction of approaching each other. At this time, the cleaning head 29 is away from the square shaft 27, and the spring 45 is in a stretched state. When the electric telescopic rod 41 is extended to drive the second cylinder 42 away from the first cylinder 24, the inclined direction of the connecting rod 43 makes the expansion movement of the cleaning head 29 slow and stuck. Through the elastic force of the stretched spring 45, the cleaning head 29 is pulled in the direction of the square shaft 27, so that the expansion adjustment of the cleaning head 29 is smoother.

[0037] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
