Detailed Description
The present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Examples
The bag material 15 conveying roller group of the embodiment is shown in fig. 1-3, and comprises a main conveying roller 1, an auxiliary conveying roller 2 and a damping roller 3 which are sequentially arranged along the conveying direction of the bag material 15, wherein the cross section of the damping roller 3 is oval, and the oval is easy to change the height of the damping roller 3, so that the tension of the bag material 15 in the conveying direction can be adjusted. The long axis of the ellipse inclines to one side of the transmission direction of the bag material 15, the bag material 15 passes through the upper surface of the damping roller 3, the lower end surface 4 of the damping roller 3 is provided with a first elastic pulling piece 5, and the upper end surface 6 is provided with a second elastic pulling piece 7; one end of the first elastic pulling piece 5 is fixed at the lower end of the damping roller 3, and the other end of the first elastic pulling piece is fixed on a plane; one end of the second elastic pulling piece 7 is fixed at the upper end of the damping roller 3, and the other end of the second elastic pulling piece is fixed on a plane; the plane of the first elastic pulling piece 5 and the plane of the second elastic pulling piece 7 are the same horizontal plane, and when the pulling force is too large, the second elastic pulling piece 7 is pressed down, so that the height of the damping roller 3 is reduced, and the tension on the bag material 15 is relieved. The shaft core 8 of the damping roller 3 is sleeved with a reset torsion spring 9, so that the damping roller 3 can automatically restore to the original height.
