Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically an adjustable support device for roll coating. Background Technology

[0002] Thermal spraying of roll coating is an advanced surface strengthening process that significantly improves the wear resistance, corrosion resistance, and service life of rolls by spraying a special material coating onto the roll surface. Thermal spraying technology uses a heat source (such as an electric arc, plasma arc, or combustion flame) to heat powdered or filamentous metal or non-metal materials to a molten or semi-molten state, and then sprays them onto the pre-treated roll surface with a high-speed airflow to form a functional coating. Support devices are required when coating rolls.

[0003] In the prior art, the roll coating support device is a special equipment used to stably support and rotate the roll during the coating process. The roll between two sets of rotating shafts can be rotated by a drive motor. The ends of the roll are usually provided with slots that match the size of the ends of the rotating shafts, so that the ends of the roll can be inserted between the two sets of rotating shafts. In the traditional roll coating support device, the height of the rotating shaft is relatively fixed, which makes it difficult to place a large diameter roll between the two sets of rotating shafts, thus making it difficult for the support device to support a large diameter roll.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2 It is understood that this utility model provides a technical solution: an adjustable support device for roller coating, including a base 1, a hydraulic cylinder 2, a slide 3, a fixed seat 4, a connecting box 5, a rotating shaft 6, and a drive motor 7. The surface of the base 1 is equipped with a hydraulic cylinder 2 for moving the slide 3. One side of the slide 3 is mounted on the telescopic end of the hydraulic cylinder 2. The fixed seat 4 is connected to the surface of the base 1. Connecting boxes 5 are provided on the tops of both the slide 3 and the fixed seat 4. Rotating shafts 6 for clamping and supporting rollers are movably connected inside both sets of connecting boxes 5. A drive motor 7 is installed on the outer side of the connecting box 5 near the fixed seat 4 to drive the rotating shaft 6 to rotate. The motor 7, slide 3 and fixed base 4 are all equipped with servo motors 8 for driving the connecting rod 9 to rotate. The two sets of servo motors 8 are controlled and driven by a set of switches. The connecting rod 9 is connected to the output end of the servo motor 8 through bearings. The outer side of the connecting rod 9 is connected to the first gear 10. The slide 3 and fixed base 4 are all equipped with threaded columns 11 for driving the moving plate 12 to rise and fall through bearings. The moving plate 12 is threaded to the outer side of the threaded column 11. The moving plate 12 is connected to the two sets of connecting boxes 5 through connecting plates 13 respectively. The outer side of the threaded column 11 is connected to the second gear 14 for meshing with the first gear 10.

[0022] exist Figure 1 and Figure 2 In the middle: the connecting plate 13 forms a sliding structure with the slide 3 and the fixed seat 4 respectively.

[0023] exist Figure 1 and Figure 2 In the middle: the sliding structure is formed between the slide 3 and the base 1.

[0024] In practical implementation, the traditional roll coating support device has two sets of rotating shafts 6 with relatively fixed heights, making it difficult for them to support rolls with large diameters. A switch can activate two sets of servo motors 8. When the servo motors 8 are running, they drive the corresponding connecting rods 9 to rotate. The rotation of the connecting rods 9 drives the first gear 10 to rotate. The rotation of the first gear 10 meshes with and drives the second gear 14 to rotate. The rotation of the second gear 14 drives the threaded column 11 to rotate. The rotation of the threaded column 11 can... The moving plate 12 is driven to slide threaded away from the second gear 14. When the moving plate 12 moves, it can drive the connecting plate 13 to rise. Thus, the connecting plate 13 can drive the corresponding two sets of connecting boxes 5 and rotating shafts 6 to rise. When the connecting boxes 5 and rotating shafts 6 rise to the specified height, the larger diameter roll can be hoisted between the two sets of rotating shafts 6. When the hydraulic cylinder 2 runs, its telescopic end can drive the slide block 3 and one set of rotating shafts 6 to move. Thus, the two sets of rotating shafts 6 can support the larger diameter roll. At this time, the roll can be sprayed.

[0025] See Figure 1 and Figure 2 It can be seen that by adjusting the height of the two sets of connecting boxes 5 and the rotating shaft 6, a larger diameter roll can be placed between the two sets of rotating shaft 6, which facilitates the support device to support the larger diameter roll and improves the practicality of the support device.

[0026] exist Figure 1 , Figure 3 and Figure 4 In the middle: The surface of the base 1 is provided with a first storage box 15 and a second storage box 16 for collecting coating particles. One end of the second storage box 16 is located on the inner surface of the first storage box 15. A T-shaped slider 17 is connected to the outer side of the first storage box 15. A guide groove 18 for sliding the T-shaped slider 17 is opened on the outer surface of the second storage box 16. Through holes 19 for inserting and fixing the plug rod 21 are opened at equal intervals on the side of the second storage box 16 away from the guide groove 18.

[0027] exist Figure 1 , Figure 3 and Figure 4 In the first storage box 15, a connecting block 20 is connected to the outside of the through hole 19. The plug rod 21 is slidably connected inside the connecting block 20. A pressure plate 22 is connected to the outside of the plug rod 21. A reset spring 23 for resetting the plug rod 21 is connected between the pressure plate 22 and the connecting block 20. The second storage box 16 is slidably connected to the first storage box 15.

[0028] In practice, after the support device supports the roll, a thermal spraying operation is performed. During the spraying process, incompletely melted particles detach from the roll surface and fall onto the surface of the base 1 below, causing contamination. The insertion rod 21 can be pulled away from the second storage box 16. As the insertion rod 21 moves, it drives the pressure plate 22 to compress the return spring 23. When the return spring 23 is compressed to a specified degree, the end of the insertion rod 21 can slide out from inside a set of through holes 19. At this time, the second storage box 16 can be pulled according to the roll size. 6. During movement, the T-shaped slider 17 slides between the guide groove 18 and the second storage box 16. When the designated set of through holes 19 on the second storage box 16 moves to the end position of the plug rod 21, the plug rod 21 can be released. At this time, the reset spring 23 can be reset, so that the plug rod 21 follows the reset spring 23 to reset. Thus, the end of the plug rod 21 can be inserted into the interior of the designated set of through holes 19 and the position of the second storage box 16 is fixed. At this time, the common size of the first storage box 15 and the second storage box 16 is the size of the roller. Then, the first storage box 15 and the second storage box 16 are placed on the surface of the base 1 below the roller.

[0029] See Figure 1 , Figure 3 and Figure 4 It can be seen that the first storage box 15 and the second storage box 16 can collect the incompletely melted particles that fall on the roller, thereby preventing the base 1 from being contaminated. The first storage box 15 and the second storage box 16 are stainless steel substrates with a polytetrafluoroethylene anti-stick coating on their surface to prevent the incompletely melted particles from sticking to the stainless steel substrate, making it convenient for personnel to clean them up later.
