After receiving the electrical signal, the microprocessor first controls the two micro electric push rods 24 to drive the pressure roller 25 to move up to the set position, and then the microprocessor controls the micro air pump 31 and the control valve 32 to work at the same time. The micro air pump 31 delivers the gas filtered by the dust screen 34 to the adsorption frame 291, and then to the gap between the touch screen 3 and the flexible texture film 4 through the multiple adsorption holes on the surface of the adsorption frame 291, so that a small gap is generated between the flexible texture film 4 and the touch screen 3. Then, the microprocessor controls the two reduction motors 21 to work for a set time, and the two reduction motors 21 drive the two rotating rollers 202 to rotate, which in turn drives the flexible texture film 4 to move on the surface of the touch screen 3. When the selected section of the flexible texture film 4 covers the surface of the touch screen 3, the microprocessor controls the two reduction motors 21, the micro air pump 31 and the control valve 32 to stop working, and the microprocessor controls the two micro electric push rods 24 to drive the pressure roller 25 to move down to the set position, so that the flexible texture film 4 covering the surface of the touch screen 3 is in a tight state. At the same time, the microprocessor also controls the micro air pump 292 to work for five seconds, which can extract the air between the touch screen 3 and the flexible texture film 4 and discharge it to the outside, thereby improving the tightness of the touch screen 3 and the flexible texture film 4. When the painter sees that there are a few bubbles between the touch screen 3 and the flexible texture film 4, he can continue to work by using the micro air pump 292 and using a hard card (such as an ID card, a bank card, etc.) to squeeze the bubbles, so that the painter's habit of using the brush is adapted to the tablet, thereby improving the painter's drawing experience.
