Description

Technical Field

[0001] The utility model relates to the field of coating machine equipment, in particular to a single-roller traction device for a coating machine. Background Art

[0002] The coating machine is used for coating glass fiber cloth with glue. A traction device is arranged at the front end of the glass fiber cloth. The traction device pulls the glass fiber cloth and transports it backward. The glass fiber cloth coil is moved by the rotation of the traction roller during operation. Therefore, the contact area between the glass fiber cloth and the traction roller and the friction force of the roller surface determine whether the coil will slip during operation. At present, the existing traction device consists of two traction rollers installed up and down or front and back. The glass fiber cloth is passed through the two traction rollers to form an "S" shape. On the one hand, the contact area between the glass fiber cloth and the traction roller is fixed. After slipping, the friction force cannot be adjusted. On the other hand, the manufacturing accuracy and installation accuracy of the traction roller itself are high, which increases the manufacturing cost. Utility Model Content
