[0016] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0018] The utility model provides a coating machine roller replacement device, which includes a working seat 1. The working seat 1 is symmetrically distributed with sliding grooves 2. A sliding frame 3 is slidably arranged in the sliding grooves 2. The sliding frames 3 are symmetrically distributed in the sliding grooves 2. A roller 301 is rotatably arranged in the sliding frame 3. A motor 302 is installed on one side of the sliding frame 3. A rotor 303 is rotatably connected in the motor 302. The rotor 303 is communicated with the roller 301. Limiting grooves 304 are arranged at the positions of the two side walls of the sliding groove 2. Sliding blocks 305 are fixedly connected to the two sides of the sliding frame 3. The sliding blocks 305 are slidably arranged in the limiting grooves 304. A fixing plate 4 is arranged at the opening position of the sliding groove 2. The fixing plate 4 is threadedly connected to the working seat 1 through a bolt 401. A pressure rod 402 is slidably connected in the fixing plate 4. A pressure block 403 is fixedly connected to the end of the pressure rod 402. The pressure block 403 abuts against the top of the sliding frame 3. A cylinder 404 is fixedly connected to the fixing plate 4. A sliding rod 405 is slidably connected in the cylinder 404. The end of the sliding rod 405 is fixedly connected to the end of the pressure rod 402 through a connecting seat 406. The end of the sliding rod 405 cooperates with the pressure rod 402 through the connecting seat 406 to ensure that the pressure rod 402 cooperates with the pressure block 403 to abut against the sliding frame 3, completing secondary limiting;

[0019] When the coating roller 301 device of the coating machine is actually used, the coating roller 301 is inserted and rotatably arranged in the sliding frame 3. The motor 302 is fixedly connected to the sliding frame 3. The rotatable rotor 303 in the motor 302 drives the roller 301 to rotate. The structure of the sliding frame 3 with the roller 301 is such that the two side sliding blocks 305 can slide in the limiting grooves 304, enabling the sliding frame 3 to slide into the sliding groove 2. After the sliding frame 3 slides into the sliding groove 2, then the staff manually threadedly connects and installs the fixing plate 4 with the bolt 401 at the position of the working seat 1. Then, the cylinder 404 drives the sliding rod 405 to drive the pressure rod 402 to move towards the sliding frame 3 until the pressure block 403 at the end of the pressure rod 402 abuts against the sliding frame 3, completing the installation and limiting work of the sliding frame 3 in the sliding groove 2. Through the setting of the sliding groove 2 structure, it is beneficial for the sliding frame 3 to cooperate with the sliding block 305 to enter the sliding groove 2 to complete preliminary limiting. Then, the fixing plate 4 driving the cylinder 404 and the component structure of the pressure rod 402 is movably connected to the working seat 1. The cylinder 404 cooperates with the sliding rod 405 to drive the pressure rod 402 to cooperate with the pressure block 403 to abut against the sliding frame 3, making the sliding frame 3 be limited and fixed in the sliding groove 2. Compared with the conventional method of using multiple groups of complex fasteners to limit and fix the roller 301, the technical solution adopted by the utility model completes preliminary limiting through the cooperation of the sliding groove 2 and the sliding frame 3, and then combines the cylinder 404 with the pressure rod 402 and the pressure block 403 to complete the secondary limiting and fixing of the sliding frame 3 in the sliding groove 2. The overall structure is compact, which is easy for the staff to install and maintain. The sliding frame 3 and the limiting and fixing components are directly installed on the working seat 1, optimizing the existing working space.

[0020] As Figure 1-2 shown, the cross-section of the pressure rod 402 is L-shaped, and the fixed plate 4, the pressure rod 402, and the pressure block 403 assembly structure are symmetrically distributed above the sliding groove 2. The cross-section of the slider 305 is a wedge-shaped structure.

[0021] The effect achieved by the entire Embodiment 1 is that during use, the slider 305 slides in the limiting groove 304 to slide the carriage 3 in the sliding groove 2, guiding the sliding of the carriage 3 in the sliding groove 2.

[0022] Working principle: The coating roller is rotatably arranged in the carriage. A motor is fixedly connected to the carriage, and the rotatable rotor in the motor drives the roller to rotate. The carriage structure with the roller is slidable by the sliders on both sides in the limiting groove, so that the carriage slides into the sliding groove. After the carriage slides into the sliding groove, then the staff manually installs the fixed plate in cooperation with bolts screwed to the working seat position. Then, the cylinder drives the sliding rod to drive the pressure rod to move towards the carriage direction until the pressure block at the end of the pressure rod abuts against the carriage, completing the installation and limiting work of the carriage in the sliding groove.
