Problems solved by technology

[0004] However, because the tension spring device is bulky and needs to be fixed, it takes up a lot of space, and it is difficult to control two or more rollers on the same roller cam, thus limiting the number of teething shafts of the folder

Embodiment Construction

[0018] Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a torsion spring locking cam paper biting mechanism includes a swing arm 2, a cam roller 3, a hollow tooth shaft 9, and a torsion spring 8. Gritting shaft 9 is a hollow shaft, and torsion spring 8 is housed in hollow teething shaft 9, and torsion spring 8 passes through hollow teething shaft 9, and the two ends of torsion spring 8 are hexagonal shafts; Hole 11 is connected, and the other end of torsion spring 8 is contained on the end cover 13, and end cover 13 is fixed on the cylinder 7. The cam roller 3 is connected on the swing arm 2 through the pin shaft 10 , and the cam roller 3 can rotate along the pin shaft 10 . Swing arm 2 is sleeved on hollow teeth-grinding shaft 9 one ends, and teeth-grinding 1 is housed on the hollow teeth-grinding shaft 9. When the swing arm 2 swings, the torsion spring 8 mounted on one end of the swing arm 2 swings together with the swing arm 2, so that the torsion spring 8 is twisted...

Abstract

The present invention belongs to the field of printing machinery, in particular, it relates to a paper-gripping mechanism of folding cylinder of folding machine. In the concrete, it is a kind of torsion spring locking cam paper-gripping mechanism. It includes the following several portions: swinging arm, gripping gear shaft, cam bowl, torsion spring, cylinder and end cover. Said invention also provides the connection mode of all the above-mentioned portions and the working principle of said paper-gripping mechanism.

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...
