Description

Technical Field

[0001] The utility model relates to the technical field of double - head roll coating, and specifically relates to a steel coil double - head roll coating device. Background Technique

[0002] The steel coil double - head roll coating device is an efficient coating equipment, mainly used for simultaneously performing roll coating operations on the front and back sides of the steel coil. The device includes a base, a conveying mechanism, a front - side roll coating mechanism, and a back - side roll coating mechanism.

[0003] In the prior art, when most rotating rollers perform roll coating operations, by using the rotation of the rotating rollers, the materials can be processed. However, most rotating rollers are fixedly arranged and cannot be adjusted, resulting in the inability to process materials with different thicknesses. Thus, thicker materials have to be processed on another set of machines. Furthermore, the non - adjustable rotating rollers may lead to difficulties in equipment adjustment, affecting the flexibility and efficiency of the production line, and thus being inconvenient for operators to use. In view of this, we introduce a steel coil double - head roll coating device. Content of the Utility Model

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a double-headed roll coating device for steel coils, including: a concave frame 1, a rotating roller A 13 is arranged inside the concave frame 1, a rotating rod A 12 is arranged inside the rotating roller A 13, and one end of the rotating rod A 12 passes through the concave frame 1 and is connected to a motor A 3;

[0025] A connecting seat 15 is arranged on one side of the concave frame 1, a rotating rod B 16 is connected inside the connecting seat 15, and a limiting roller 14 is sleeved on the surface of the rotating rod B 16;

[0026] A concave bracket 9 is arranged inside the concave frame 1, a rotating roller B 10 is arranged inside the concave bracket 9, a rotating rod C 11 is connected inside the rotating roller B 10, and the rotating rod C 11 passes through the concave bracket 9 and the concave frame 1;

[0027] A driving mechanism is provided at the top of the concave frame 1. The motor B4 of the driving mechanism drives the sleeve 6 and the threaded rod 5 to rotate, so as to drive the concave frame 9 and the rotating roller B10 to adjust through the threaded rod 5.

[0028] The driving mechanism includes a worm gear 8 sleeved on the surface of the sleeve 6. The worm gear 8 is fixedly arranged with the sleeve 6. The motor B4 is connected to the top of the concave frame 1 and is fixed to the top of the concave frame 1 by bolts. The output end of the motor B4 is connected with a connecting rod 7. The threaded rod 5 is connected to the top of the concave frame 9 and penetrates through the concave frame 9. A bearing 26 is sleeved at the bottom of the threaded rod 5, and the bearing 26 is embedded into the interior of the concave frame 9. The sleeve 6 is screwed with the threaded rod 5. One side of the connecting rod 7 is connected with a worm 21, and the worm 21 is screwed with the worm gear 8.

[0029] One side of the rotating rod C11 penetrates through the concave frame 1 and is connected with a motor C2. After the motor C2 is started, it can drive the rotating rod C11 to rotate.

[0030] A hollow groove 25 for sliding the rotating rod C11 is formed on the surface of the concave frame 1. The hollow groove 25 and the concave frame 1 are integrally formed, which can allow the rotating rod C11 to move inside the hollow groove 25.

[0031] One side of the connecting seat 15 is connected with a fixed box 18. The fixed box 18 is fixedly arranged with the connecting seat 15. The number of the fixed boxes 18 is two groups. A rotating rod D24 is connected between the two groups of fixed boxes 18. A cleaning rod 19 is connected to the surface of the rotating rod D24. The rotating rod D24 is fixedly arranged with the cleaning rod 19. A scraping plate 20 is connected to the surface of the cleaning rod 19. A rotating mechanism is arranged inside one of the fixed boxes 18.

[0032] The rotating mechanism includes a bevel gear A23 connected to one side of the rotating rod D24. The bevel gear A23 is connected inside the fixed box 18. A bevel gear B22 is meshed with the surface of the bevel gear A23. A hand wheel 17 is connected to the top of the bevel gear B22. By driving the bevel gear B22 to rotate through the hand wheel 17, since the surface of the bevel gear B22 is meshed with the bevel gear A23, at this time, the rotating rod D24, the cleaning rod 19 and the scraping plate 20 can be driven to rotate through the bevel gear A23.

[0033] A T-shaped limiting rod 27 is connected to the top of the concave frame 9 and penetrates through the concave frame 1. The T-shaped limiting rod 27 is used to limit the movement of the concave frame 9, so that the concave frame 9 can always move smoothly up and down in a vertical state. The lifting height of the T-shaped limiting rod 27 is slightly less than the length of the threaded rod 5, so as to effectively avoid the situation that the sleeve 6 and the threaded rod 5 fall off.

[0034] Specifically, during use, start the motor B4, and let the output end of the motor B4 drive the connecting rod 7 and the worm 21 to rotate. Since the worm 21 meshes with the worm wheel 8, the worm wheel 8 will drive the sleeve 6 to rotate on the top of the concave frame 1. Since the sleeve 6 and the threaded rod 5 are meshed, the threaded rod 5 will move downward inside the sleeve 6, thereby driving the concave frame 9 and the rotating roller B10 to move downward through the threaded rod 5, and then coating the steel coil plate. When the rotating roller B10 is adjusted inside the concave frame 1, it can be applied to steel coil plates of different sizes and thicknesses, making it more convenient to use;

[0035] Rotate the handwheel 17 to drive the bevel gear B22 to rotate. Since the surface of the bevel gear B22 meshes with the bevel gear A23, the rotating rod D24, the cleaning rod 19 and the scraper 20 can be driven to rotate through the bevel gear A23. By using the rotation of the scraper 20, the scraper 20 contacts the limiting roller 14, so as to scrape off the sundries on the surface of the limiting roller 14, making it more convenient to use.
