[0019] Please see Figures 1-4 This utility model proposes a coating machine scraper adjustment device, including a mounting frame 1 and a mounting plate 2. The mounting frame 1 is provided with a scraper adjustment mechanism 3, which includes a scraper holder 31, a limiting rod 34 and a fixing component 36. A scraper 32 is detachably connected to the bottom of the scraper holder 31, and a threaded rod 33 is rotatably connected to the scraper holder 31. The limiting rod 34 passes through the mounting frame 1 and is slidably connected to the mounting frame 1. A rotating component 35 is provided on the threaded rod 33, and the fixing component 36 is provided on the mounting frame 1.

[0020] In this embodiment of the utility model, in order to stabilize the scraper 32 and ensure its stability after adjustment, specifically, the threaded rod 33 passes through the mounting bracket 1 and is slidably connected to the mounting bracket 1. Two sets of fixing components 36 are provided, with the two sets of fixing components 36 located on both sides of the threaded rod 33. The rotating component 35 includes a fixing cylinder 351, with a sliding groove 352 inside the fixing cylinder 351. A sliding block 353 is slidably connected to the sliding groove 352. The sliding block 353 is connected to the inner surface of the fixing cylinder 351. The wall is elastically connected by a return spring. A rotating rod 354 is fixedly connected to the upper side of the sliding block 353. A limit ring 355 is fixedly connected to the outer wall of the rotating rod 354. A connecting piece 356 is sleeved on the outer wall of the rotating rod 354. The fixed cylinder 351 is sleeved with the rotating rod 354. The connecting piece 356 slides with the limit ring 355. Two sets of limit rings 355 are provided, and the connecting piece 356 is located between the two sets of limit rings 355 and is limited by the two sets of limit rings 355. The fixing assembly 36 includes an elastic telescopic rod 361. The sleeve of the telescopic rod 361 is fixedly connected to the mounting bracket 1. The telescopic end of the elastic telescopic rod 361 is fixedly connected to a clamping block 362. The inner surface of the clamping block 362 is provided with a reverse thread.

By rotating the clamping screw 23, the pressure ring 24 is moved away from the mounting frame 1, and the mounting frame 1 can be rotated to a horizontal position, making it convenient for workers to replace or clean the scraper 32.

[0022] In use, first press the rotating rod 354 to make the sliding block 353 slide downward in the sliding groove 352, compressing the return spring, which in turn drives the limit ring 355 and the connecting piece 356 to descend. At this time, the connecting piece 356 drives the hinge rod 363 to move, and the telescopic part of the elastic telescopic rod 361 retracts, causing the clamping block 362 to move away from the threaded rod 33. Then, rotating the rotating rod 354 can adjust the height of the scraper 32. After releasing the rotating rod 354, the return spring drives the rotating rod 354 to reset, the connecting piece 356 to reset, and then the clamping block 362 clamps the threaded rod 33. When it is necessary to replace or clean the scraper 32, by rotating the clamping screw 23, the pressure ring 24 is moved away from the mounting bracket 1, and the mounting bracket 1 can be rotated to a horizontal position, and then the scraper 32 can be replaced or cleaned.
