Continuous forming traction device for single-layer paper straws

The invention relates to the field of paper straw processing, in particular to a single-layer paper straw continuous forming traction device which comprises a support, two parallel bearing frames are sequentially arranged on one side of the support from top to bottom in the height direction of the support, and belt wheels are rotationally connected to the inner side walls of the two ends of each bearing frame. The two belt wheels located on the same bearing frame are in transmission connection through a belt, and a power source used for driving the belt wheels to rotate is arranged on the support. Adjusting sliding blocks are arranged on the two opposite side walls of the end, away from the power source, of the bearing frame in the conveying direction of the paper suction pipes in a sliding mode, the belt wheel away from the power source is rotationally connected between the two adjusting sliding blocks, and adjusting pieces used for driving the adjusting sliding blocks to slide are arranged on the bearing fr
