[0018] To better understand the above objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0019] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0020] The present utility model provides a coating liquid control device for a coating machine, including a working frame 1. A guiding roller 2 is rotatably connected in the working frame 1. A coating roller 201 is rotatably arranged above the guiding roller 2. A motor 202 is installed on the working frame 1. The motor 202 is communicated with the coating roller 201 through a rotor 203. A replenishing tank 3 is fixedly connected above the coating roller 201 through a bracket 306. A partition 301 is slidably connected in the replenishing tank 3. A replenishing port 302 is installed on the top of the replenishing tank 3. The end structure of the replenishing tank 3 is conical. A stirring paddle 303 is rotatably connected in the replenishing tank 3. A motor 304 is fixedly connected to the outer wall of the replenishing tank 3. The motor 304 is communicated with the stirring paddle 303 through a rotating shaft 305. The motor 304 drives the rotating shaft 305 to drive the stirring paddle 303 to rotate, and the stirring paddle 303 is fully mixed in the replenishing tank 3.

[0021] When the coating liquid control device of the coater is actually in use, before delivering the coating liquid to the coating roller 201, the coating liquid needs to be replenished into the replenishing liquid tank 3 from the position of the replenishing port 302. Then, the motor 304 drives the stirring paddle 303 to rotate in the replenishing liquid tank 3 in cooperation with the rotating shaft 305 to fully mix the coating liquid in the replenishing liquid tank 3. When it is necessary to supply the coating liquid to the coating roller 201, the electric cylinder 5 drives the sliding rod 501 to move, and then the fastener 502 cooperates with the partition plate 301 to move away from the receiving groove 4. The limiting block 401 on the partition plate 301 moves out of the receiving groove 4, so that the coating liquid flows out of the replenishing liquid tank 3 and directly acts on the coating roller 201. Then, the motor 202 on the working frame 1 drives the rotor 203 to drive the coating roller 201 to rotate, so as to rotate the coating roller 201 and cooperate with the guiding roller 2 to perform the coating work. By slidingly connecting the partition plate 301 structure in the replenishing liquid tank 3, the electric cylinder 5 drives the sliding rod 501 to move, and the sliding rod 501 cooperates with the partition plate 301 to slide in the replenishing liquid tank 3 until the limiting block 401 moves out of the receiving groove 4, and the coating liquid in the replenishing liquid tank 3 overflows from the position of the generated gap and directly acts on the position of the coating roller 201. Compared with the conventional coating discharging method that is not easy to control, the technical solution adopted in this utility model can evenly coat the coating liquid in the coating tank on the coating roller 201, improve the processing quality of the coater in the later stage, the overall structure is directly installed on the coater, optimizing the existing working space, the overall structure is compact, and it is easy for the staff to install and maintain.

[0022] As Figures 1-4 shown, a receiving groove 4 is provided on the replenishing liquid tank 3. A limiting block 401 is fixedly connected to the left side of the partition plate 301. The limiting block 401 and the receiving groove 4 fit each other. An electric cylinder 5 is fixedly connected to the outer wall of the replenishing liquid tank 3. A sliding rod 501 is slidably connected in the electric cylinder 5. The sliding rod 501 and the partition plate 301 are connected by a fastener 502. When the limiting block 401 and the receiving groove 4 are in contact, the joint is relatively sealed. The contact position between the sliding rod 501 and the replenishing liquid tank 3 is sealed.

[0023] The effect achieved by the entire embodiment 1 is that during use, the electric cylinder 5 drives the sliding rod 501 to move, and then the fastener 502 cooperates with the partition plate 301 to move away from the receiving groove 4. The limiting block 401 on the partition plate 301 moves out of the receiving groove 4, so that the coating liquid flows out of the replenishing liquid tank 3 and directly acts on the coating roller 201. The contact position between the sliding rod 501 and the replenishing liquid tank 3 is sealed to ensure the relative seal at the joint position.

[0024] Working principle: Before the coating needs to be conveyed to the coating roller, the coating liquid is replenished into the liquid replenishing tank from the position of the supply port. Then, the motor drives the stirring paddle to rotate in the liquid replenishing tank through the rotating shaft, so as to fully mix the coating liquid in the liquid replenishing tank. When the coating needs to be fed to the coating roller, the electric cylinder drives the sliding rod to move, and then the fastener and the partition move away from the accommodating groove. The limiting block on the partition moves out of the accommodating groove, so that the coating liquid flows out of the liquid replenishing tank and directly acts on the coating roller. Then, the motor on the working frame drives the rotor to drive the coating roller to rotate, so as to rotate the coating roller and cooperate with the guide roller to carry out the coating work.
