[0025] A single-sided stable coating device includes a coating box 1, a stepper motor 2, and a coating gravure roller 3 disposed inside the single-sided coating device. The stepper motor 2 is fixedly mounted at the front end of the coating box 1, and the coating gravure roller 3 is fixedly mounted at the end of the main shaft of the stepper motor 2. Two wing plates 4 are symmetrically fixedly mounted on the top left and top right sides of the coating box 1. A flexible scraper 5 is fixedly mounted on the top of the right wing plate 4. A sleeve 6 is fixedly mounted inside the bottom end of the coating box 1, and a control cylinder 7 is fixedly mounted at the bottom end of the sleeve 6. The end is fixedly equipped with an inlet tank 8 and an outlet tank 9. A heat conduction pipe 10 is fixedly connected to the inlet tank 8 and the outlet tank 9. A limit plate 11 is fixedly installed on the inner wall of the left end of the coating box 1. A connecting rod 12 is installed at the bottom of the limit plate 11. A float plate 13 is fixedly installed at the top of the connecting rod 12. An inner conical ring 14 is fixedly installed on the outer side of the bottom of the connecting rod 12. A ring cylinder 15 is fixedly installed at the bottom end of the inner conical ring 14. An outer conical ring 16 is fixedly installed on the inner wall of the control cylinder 7. The bottom end of the control cylinder 7 is connected to the solenoid valve device.

[0026] The bottom port of the water inlet tank 8 is connected to the water inlet pipe of the external hot water circulation system, and the bottom port of the water outlet tank 9 is connected to the drain pipe of the external hot water circulation system. Through the above configuration, the heat of the hot water is used to heat the coating liquid inside the coating box 1 through the heat conduction pipe 10, which helps to remove the air bubbles trapped inside the coating liquid.

[0027] A connecting pipe is fixedly connected to the inside of the left end of the coating box 1 and the inside of the left end of the control cylinder 7. Through the above arrangement, the coating box 1 and the control cylinder 7 are connected.

[0028] The ring cylinder 15 has a through hole inside, and the connecting rod 12 is slidably connected to the rubber ring inside the sleeve 6. Through the above arrangement, the connecting rod 12, float plate 13, inner cone ring 14 and ring cylinder 15 form an integrated valve stem assembly.

[0029] The rubber ring on the outer side of the inner cone ring 14 is in close contact with the rubber ring on the inner side of the outer cone ring 16. Through the above arrangement, a sealing structure is formed between the inner cone ring 14 and the outer cone ring 16.

[0030] Work process: This utility model provides a single-sided stable coating device. The main body of the device facilitates the supply and degassing treatment of the coating liquid inside the single-sided coating device, which is used to improve the stability of the coating gravure roller 3 continuously dipping into the coating liquid.

[0031] The bottom of the solenoid valve device is connected to the liquid supply tank via an external liquid supply pump. The external hot water circulation system, solenoid valve, liquid supply pump, and stepper motor 2 are controlled by an external PLC controller. The external hot water circulation system, solenoid valve, liquid supply pump, and stepper motor 2 are electrically connected via an external power supply device.

[0032] The connecting rod 12, float 13, inner conical ring 14, and ring cylinder 15 form an integrated valve stem assembly. When the liquid level of the coating liquid inside the coating box 1 drops, the connecting rod 12, float 13, inner conical ring 14, and ring cylinder 15 move downwards until the bottom end of the ring cylinder 15 contacts the inner wall of the bottom end of the control cylinder 7. The collision between the bottom end of the ring cylinder 15 and the inner wall of the control cylinder 7 generates noise. The external noise sensing component receives the signal, and the external PLC controller controls the solenoid valve and the liquid supply pump to start. The internal structure of the connecting pipe between the control cylinder 7, the coating box 1, and the control cylinder 7 is interconnected, used to input the coating liquid into the coating box 1. The coating liquid level inside the coating box 1 rises until the top of the float plate 13 contacts the bottom of the limiting plate 11. The rubber ring on the outer side of the inner cone ring 14 and the rubber ring on the inner side of the outer cone ring 16 contact each other to form a sealing structure. The bottom port of the water inlet tank 8 is connected to the water inlet pipe of the external hot water circulation system, and the bottom port of the water outlet tank 9 is connected to the drainage pipe of the external hot water circulation system. The heat of the hot water is used to heat the coating liquid inside the coating box 1 through the heat conduction pipe 10, which helps to remove air bubbles trapped inside the coating liquid and improves the stability of the coating gravure roller 3 continuously dipping into the coating liquid.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
