The film material pulling and conveying device is generally composed of a driving wheel, a driven wheel and a motor, wherein the driving wheel and the driven wheel clamp the film material, the motor drives the driving wheel to rotate so as to pull the film material to be conveyed outwards, but after the film material pulling and conveying device operates for a period of time, the film material can deviate, and at the moment, the position of the film material is required to be manually readjusted.

When the thickness of two sides of the film material is uneven in the material pulling process, the friction force between the driving wheel and the driven wheel is different, the thicker the material of the film material is, the larger the friction force between the driving wheel and the driven wheel is, and the material can shift to the position when the material is pulled. In addition, the error in the machining dimension between the driving wheel and the driven wheel, or the larger error in the actual dimension between the driving wheel and the driven wheel and the preset dimension due to the longer use time, may also cause the above-mentioned deviation phenomenon.
