Description

Technical Field

[0001] This utility model relates to the field of sandblasting device technology, specifically a multi-link automatic sandblasting mechanism. Background Technology

[0002] A sandblasting machine uses compressed air as power to mix sand and air to form a high-speed jet that propels the abrasive material along the conveying pipe at high speed onto the surface of the workpiece to be treated. This causes the adhering substances on the surface of the workpiece to peel off or changes the mechanical properties of the outer surface.

[0003] Most of the nozzles in existing sandblasting devices are fixedly installed, making it inconvenient to adjust their position and angle after installation. This results in the sandblasting range of the sandblasting mechanism being unadjustable and unsuitable for sandblasting workpieces of different shapes, leading to poor applicability of the sandblasting mechanism. Therefore, a multi-link automatic sandblasting mechanism is proposed. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-link automatic sandblasting mechanism, including a fixed frame 1 and a sandblasting box 3. The sandblasting box 3 is fixedly installed on the top of the fixed frame 1. A control box 2 is also provided on the side wall of the sandblasting box 3. A conveying roller 4 is connected to the inner side of the fixed frame 1. The workpiece is conveyed by the conveying roller 4. The workpiece is placed on the conveying roller 4 at the front end of the fixed frame 1, and the workpiece is moved to the end. During the movement, the workpiece passes through the sandblasting box 3 for sandblasting. The sandblasting box 3 is provided with a sandblasting chamber inside, and a chamber door 8 is hinged to the opening of the sandblasting chamber. Four sandblasting shafts 17 are provided inside the sandblasting chamber for sandblasting. Several sandblasting mechanisms are installed on the shaft 17 to spray sand. The two ends of the sandblasting shaft 17 extend to the outer wall of the sandblasting box 3 and are respectively connected to the positioning plate 9 and the positioning plate 14. A crank 10 is installed on the right end of one of the sandblasting shafts 17. The end of the crank 10 is rotatably connected to the drive rod 11. A motor 13 is fixed on one side of the top of the sandblasting box 3 and an adjustment plate 12 is connected to the power output end of the motor 13. The adjustment plate 12 is rotatably connected to the crank. The motor 13 drives the adjustment plate 12 to rotate. During the rotation of the adjustment plate 12, the drive rod 11 drives one of the sandblasting shafts 17 to rotate.

[0023] In a further improvement, one end of the sandblasting shaft 17 extending to the positioning plate 2 14 is connected to a crank 2 16. The ends of adjacent crank 2 16 are connected by a connecting rod 15. The connecting rod 15 is rotatably connected to the crank 2 16. After one sandblasting shaft 17 rotates, it drives the other sandblasting shafts 17 to rotate synchronously through the connecting rod 15 and the crank 2 16.

[0024] Further improvements include an upper mounting plate 8 and a lower mounting plate 19. Mounting grooves 20 are formed on opposite surfaces of the upper and lower mounting plates 8 and 19, and these grooves 20 fit snugly against the surface of the sandblasting shaft 17. The upper mounting plate 8 and lower mounting plate 19 are bolted together for easy installation and disassembly, facilitating adjustment of the sandblasting mechanism's position on the sandblasting shaft 17. An upper adjusting rod 22 is movably mounted on the surface of the lower mounting plate 19, and a positioning bolt 21 is threaded onto the side wall of the lower mounting plate 19. Loosening the positioning bolt 21 allows adjustment of the position of the upper adjusting rod 22, after which the housing is tightened. An adjusting shaft 23 is fixedly connected to the end of the upper adjusting rod 22, and a lower adjusting rod 24 is rotatably connected to the adjusting shaft 23. A nozzle 25 is fixedly attached to the end of the lower adjusting rod 24, facilitating adjustment of the sandblasting angle of the nozzle 25.

[0025] In a further improvement, a fixing plate 5 is provided on one side of the top of the sandblasting box 3. Several instruments 6 are evenly arranged on the surface of the fixing plate 5, and a control button 7 is installed on the surface of the fixing plate 5 and below the adjacent instruments 6. The control button 7 controls the sandblasting operation, and the instruments 6 display the working status.

[0026] Working principle: The workpiece is placed on the conveyor roller 4 at the front end of the fixed frame 1, which drives the workpiece to move to the end. During the movement, it passes through the sandblasting box 3 for sandblasting. During the sandblasting process, the motor 13 is started. The motor 13 drives the drive rod 11 through the adjustment plate 12. The drive rod 11 drives the crank 10 and drives one of the sandblasting shafts 17 to rotate. After the sandblasting shaft 17 rotates, it drives the other three sandblasting shafts 17 to swing synchronously through the crank 16 and the connecting rod 15. During the swing, sand is sprayed out through the nozzle 25, which can achieve multi-angle large coverage sandblasting and improve the sandblasting quality. When the sandblasting mechanism needs to be adjusted, loosen the bolts on the upper mounting plate 8 and the lower mounting plate 19, and then adjust their position on the sandblasting shaft 17. After loosening the positioning bolt 21, the upper adjustment rod 22 can be adjusted. After rotating the lower adjustment rod 24, it can be rotated around the adjustment shaft 23 for adjustment. This can improve the applicability of the sandblasting mechanism and facilitate sandblasting of workpieces of different shapes and sizes.
