Description

(1) Technical field

[0001] The invention relates to a printing machine, in particular to a paper biting mechanism of a folding cylinder of a folding machine. (2) Background technology

[0002] The teeth splint on the folding cylinder of the existing folding machine is controlled by the swing arm cam, see Figure 1, the cam 5 is fixed on the frame, the roller 3 is installed on the swing arm 2, and the swing arm 2 is set on the teeth shaft 6 , the roller 3 drives the swing arm 2 to swing relatively with the rotation of the drum. The locking force is provided for the cam roller 3 through the tension spring device 4, so that the cam roller 3 always keeps in contact with the cam 5.

[0003] The working process of biting the paper is: after the folding cylinder rotates, it drives the teething shaft mounted on it through the bearing to rotate. The teething shaft is equipped with a swing arm. Since one end of the swing arm is equipped with a roller, and the roller is acted by the lo...
