Description

Technical Field

[0001] This utility model relates to a liquid tube guiding and locking mechanism and a coating device. Background Technology

[0002] Coating apparatus typically includes a coating liquid tank, which uses a coating liquid pipe to deliver the coating liquid in the tank to a coating liquid pump, and then the coating liquid pump delivers the coating liquid to the coating head for coating.

[0003] In existing technologies, such as Figure 6 As shown, the coating liquid pipe 6 is usually inserted directly into the coating liquid tank 4 through the tank cover 5 to deliver the coating liquid. However, this method has the following problems.

[0004] First, the coating liquid tube 6 is usually made of a flexible tube such as a Teflon tube, which can sometimes bend or curl up. When the coating liquid is stirred with an electric stirrer 7, a stirring oscillator 8 is present in the coating liquid tank 4. The bent or curled coating liquid tube 6 can easily interfere with the stirring oscillator 8, affecting the stirring effect of the coating liquid (for example, when the coating liquid contains pigments or other dispersions, precipitation is likely to occur).

[0005] Secondly, the coating liquid tube 6 extends directly into the coating liquid, and its depth of insertion is uncontrollable. Furthermore, when multiple coating liquid tubes 6 need to be inserted into the coating liquid tank 4, the depths of insertion are inconsistent (large deviations). As the liquid level in the tank 4 drops, the higher-positioned coating liquid tube 6 is exposed, allowing air to enter and easily generating bubbles, resulting in poor coating. Utility Model Content
