Problems solved by technology
[0003] However, the liquid level sensor used in the existing liquid supply tank can only monitor the level of the liquid level and give an alarm to remind the staff to add liquid to the liquid supply tank. It cannot automatically drive the mechanism to add liquid and extend the coating time. Secondly, The liquid level sensor is an electronic device, which must be connected to the circuit during use, and there will be sensor failure and inaccurate monitoring data after long-term use. Therefore, those skilled in the art provide a liquid level sensor for the liquid supply tank of the coating machine. sensor, to solve the problems raised in the above-mentioned background technology

The invention belongs to the technical field of sensors and relates to a coating machine liquid supply box liquid level sensor. A liquid injection port is formed in the upper surface of a liquid supply box and located on one side of a baffle; a gear is engaged with the bottom end of a toothed plate; a first connecting plate is movably connected to the outer surface of the gear; a limiting plate isfixedly connected to the inner wall of a sealing plate; a push plate is slidably connected to the interior of the limiting plate; a liquid level plate is fixedly connected to the bottom end of the push plate and located in the liquid supply box; a prompt plate is movably connected to one end of a movable plate; a magnet is fixedly connected to one end of the prompt plate; due to mutual repulsionof homopolar magnets, the liquid level plate and the magnets repel each other; when the liquid level plate moves to the magnets with different heights, the prompt plate at the corresponding position extends outwards, the function of liquid level height prompt is achieved; the mechanism does not need to be connected with an external power source to realize control, so that the effects of saving energy and accurately prompting the liquid level height are achieved.
Description
Technical field[0001]The invention relates to the technical field of sensors, in particular to a liquid level sensor of a liquid supply tank of a coating machine.Background technique[0002]Coating machine is mainly used for surface coating process production of film, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then winds it after drying. The paint used is placed in the liquid supply tank, and a liquid level sensor is usually used to monitor the height of the liquid level drop.[0003]However, the existing liquid level sensor used in the liquid supply tank can only detect the height of the liquid level and give an alarm to remind the staff to add liquid to the liquid supply tank. It cannot automatically drive the mechanism to add liquid and extend the coating time. Secondly, The liquid level sensor is an electronic device, which must be connected to the circuit during use, and after a long period of use, there will ...
