1. The function of the open rotary screen printer tensioning device for the cloth: the tensioning device can adjust the angle arbitrarily according to the needs, so by rubbing the fabric, the required radial tension can be obtained on the fabric. Operation: Increase the radial tension of the fabric: Turn the hand wheel 4, so that the wrap angle of the fabric increases. Reduce the radial tension of the fabric: Turn the hand wheel 4, so that the wrap angle of the fabric is reduced.

Maintenance: visually inspect the roller shaft, handle adjustment device, and transmission gear-check whether the traction roller is obviously damaged, worn and the bearing seat is intact. Cleaning—Clean the traction roller with a suitable cleaning device. Do not use sharp or hard tools to clean the surface of the roller. Bearing: Lubricant-the bearing is a lubrication-free bearing. Rotation-The bearing must rotate flexibly, and if there is a problem, it needs to be replaced in time.

2. Mopping roller function: When selecting and configuring the equipment, a traction roller is generally placed at the cloth entry point. The device is driven by a motor with a gearbox, and there is also a traction roller at the cloth outlet. Function: Towing the fabric to run.
3. Brake roller (brake) function: When it is not braking, the brake roller is driven by the fabric, energizing the pneumatic brake to slow down the roller, thereby increasing the tension of the fabric. Operation: increase the radial tension of the fabric: through the pressure reduction valve 1, increase the pressure of the brake roller, and the fabric tension increases. Reduce the diameter of the fabric: Through the pressure reduction valve 1, the pressure of the brake roller is reduced, and the tension of the fabric is reduced.

Fourth, the function of the pressure roller: in order to improve the guiding effect of the traction roller, the fabric is between the pressure roller and the traction roller, and the pressure roller presses on the traction roller by its own weight and the pressure of the air cylinder.

5. Hot Air Stenter mechanism function: There is a cloth accumulation mechanism at the entrance and exit of the cloth, which is suitable for both wet and dry cloth. The cloth accumulation mechanism is composed of a storage box, which can store 300M-500M according to the weight of the cloth.

Maintenance: visual inspection—check whether the fabric accumulation box 1 has obvious faults and whether all parts are normal. The place where the fabric is placed on the surface of the fabric accumulation box should not be sharply damaged.
