Laboratory coating machines are widely used in various scientific research experiments, such as materials science, chemical engineering, and electronic engineering. In these fields, coating machines are used to test the performance of adhesives, coatings, or inks, the adhesion of coatings, and other key indicators. Through laboratory coating machines, researchers can precisely control parameters such as coating speed, coating amount, and coating thickness, thereby ensuring the accuracy and repeatability of experimental results.

A fan 206 is fixedly installed in the inner cavity of the positioning frame 205. There are several fans 206. By setting up the drying mechanism 2, the coated material can be dried. At the same time, the height of the coated material can be adjusted by using the electric telescopic rods 201 to extend its stroke, thereby improving the drying quality of the material. Furthermore, the height of the coating roller 9 can be adjusted by using the dual-axis motor 5 to drive the two cams 7 to rotate, so that the distance between the coating roller 9 and the back pressure roller can be precisely controlled to control the coating thickness.

[0034] Working principle: During use, the operator starts the dual-axis motor 5 using an external control switch. The output ends on both sides of the dual-axis motor 5 drive the two transmission rods 6 to rotate in the same direction. When the two transmission rods 6 rotate, they drive the two cams 7 to rotate. When the two cams 7 rotate, they squeeze the two T-blocks 8, causing the T-blocks 8 to move downward. After being squeezed, the T-blocks 8 squeeze the spring 11, which in turn drives the coating roller 9 to move downward. By adjusting the height of the coating roller 9, the gap between the coating roller 9 and the back pressure roller can be adjusted. During the material coating process, the operator starts the electric heating roller 203, the electric heating plate 204, and the fan 206 using an external control switch. The electric heating roller 203 and the electric heating plate 204 can accelerate the drying of the coating. When the coating is thick, the operator starts the electric telescopic rod 201. The electric telescopic rod 201 drives the fixed frame 202 and the electric heating roller 203 to move upward, which can adjust the height of the coated material, extend its stroke, and thus improve the drying quality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
