Description

Technical Field

[0001] This invention relates to the field of fire-resistant cable production technology, and in particular to a powder coating device for fire-resistant cable production. Background Technology

[0002] The invention disclosed in CN117059335A, applicable to the field of cable production technology, provides a powder coating device for fire-resistant cable production. The device includes a main body comprising a powder spraying cylinder and a cleaning cylinder. A driving assembly is mounted on the powder spraying cylinder. The device also includes a cleaning assembly comprising clamping plates and an adjusting sleeve. An adjusting assembly is located on the outer side wall of the cleaning cylinder. Multiple clamping plates are arranged in a ring within the cleaning cylinder. A first connecting rod and a second connecting rod are rotatably mounted on the side of each clamping plate near the inner wall of the cleaning cylinder. The end of the first connecting rod away from the clamping plate is rotatably mounted on the inner wall of the cleaning cylinder, and the end of the second connecting rod away from the clamping plate is rotatably mounted on the inner wall of the adjusting sleeve. A brush and a flexible friction layer are provided on the side of the clamping plate near the axis of the cleaning cylinder, along with the powder coating assembly. This device is applicable to cables of various sizes, enabling automatic cleaning and powder coating of cables with a high degree of automation and good performance.

[0003] The existing technology uses a motor to drive a cleaning cylinder to rotate, which in turn drives a brush to clean the surface of the fireproof cable in a circular motion. However, due to the low friction between the brush and the fireproof cable, the cleaning effect is poor, and the generated static electricity is also poor, making it difficult for the subsequent powder to adhere to the fireproof cable. Therefore, a powder coating device for fireproof cable production is needed to meet people's needs. Summary of the Invention

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all 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 12, and several nozzles 13. The support leg 11 is connected to the bottom end of the tank 12. Both ends of the tank 12 are closed and have through holes 14. Several nozzles 13 are evenly distributed in a circular shape on the inner wall of the tank 12. 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 external gear ring 23, a first cylinder 24, a first connecting shaft 25, a first helical gear 26, a square shaft 27, a slide tube 28, and a cleaning head 29. A linkage mechanism 3 is provided between the cleaning mechanism 2 and the powder coating mechanism 1. The linkage mechanism 3 consists of an internal gear ring 31, a driven gear 32, a fixed gear 33, a sleeve 34, a second connecting shaft 35, and a second helical gear 36.

[0029] Reference Figure 3 and Figure 6 In this embodiment, the motor 21 is mounted on the tank 12, the transmission gear 22 is connected to the output end of the motor 21, the external 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 helical gear 26 is connected to the other end of the first connecting shaft 25, the square shaft 27 is connected to the first helical gear 26, the slide tube 28 is slidably connected to the square shaft 27, and the cleaning head 29 is connected to the slide tube 28.

[0030] Reference Figure 4 and Figure 6-7 In this embodiment, the internal 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 meshes between the internal gear ring 31 and the fixed gear 33, the driven gear 32, the second connecting shaft 35 and the second helical gear 36 are connected, the sleeve 34 is sleeved on the second connecting shaft 35 and the second helical gear 36, the second helical gear 36 meshes with the first helical gear 26, and one end of the first connecting shaft 25 is rotatably connected inside the sleeve 34.

[0031] Working principle: Motor 21 drives transmission gear 22 to rotate. Transmission gear 22 meshes with external gear ring 23, causing the first cylinder 24 to produce a circular motion. Since the first connecting shaft 25 is rotatably connected inside the side wall of the first cylinder 24, the first connecting shaft 25 follows the first cylinder 24 in a circular motion. Through the connection of the first helical gear 26, square shaft 27 and slide tube 28, the cleaning head 29 follows the first cylinder 24 in a circular motion. At the same time, the circular motion of the first cylinder 24 drives the internal gear ring 31 to rotate. Since the fixed gear 33 is connected to the tank 12 and is in a relatively stationary state, the driven gear 32 rotates on the fixed gear 33 under the drive of the internal gear ring 31. 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... Without rotation, the second connecting shaft 35, driven by the driven gear 32, causes the second helical gear 36 to rotate. Through the meshing of the first helical gear 26, the square shaft 27 drives the slide tube 28 to rotate. The slide tube 28 drives the cleaning head 29 to rotate, increasing the friction between the cleaning head 29 and the surface of the fireproof cable, improving the cleanliness of the fireproof cable surface, and generating static electricity on the surface of the fireproof cable. After cleaning, the fireproof cable enters the powder coating mechanism 1, passes through the perforation 14 on one side and enters the tank 12. The powder is sprayed all over the surface of the fireproof cable through the circumferentially distributed nozzles 13. The enhanced static electricity effect through 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 using 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 formed on one end of the tank body 12. The single-sided 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, providing a positioning effect for the rotation of the driven gear 32 in circular motion, preventing the driven gear 32 from shaking, and improving the stability of the meshing transmission between the driven gear 32, the internal gear ring 31 and the fixed gear 33.

[0033] Reference Figure 6 In this embodiment, the first cylindrical body 24 is fitted into one end of the tank body 12, and the outer wall of the embedded part is radially extended, which ensures that the first cylindrical body 24 rotates on one end of the tank body 12, while preventing separation and improving 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 12. The adjustment mechanism 4 consists of an electric telescopic rod 41, a second cylinder 42, a connecting rod 43, and a collar 44. The electric telescopic rod 41 is connected between the second cylinder 42 and the first cylinder 24. The collar 44 is sleeved on the cleaning head 29. One end of the connecting rod 43 is rotatably connected to the collar 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 rotational connection of the connecting rod 43 and the guiding effect formed between the square shaft 27 and the slide tube 28, the collar 44 drives the cleaning head 29 to move. The slide tube 28 follows the cleaning head 29 to move on the square shaft 27, and the connection between the collar 44 and the cleaning head 29 does not hinder the 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 inside 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 retracts and drives the second cylinder 42 to move closer to the first cylinder 24, the tilt direction of the connecting rod 43 allows the collar 44 to smoothly drive the cleaning head 29 to move closer to 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 extends and drives the second cylinder 42 away from the first cylinder 24, the tilt direction of the connecting rod 43 makes the expansion movement of the cleaning head 29 relatively slow and stuck. Through the elastic force of the stretched spring 45, the cleaning head 29 is pulled towards the square shaft 27, thereby making the expansion adjustment of the cleaning head 29 smoother.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
