Description

Technical Field

[0001] The utility model relates to the technical field of film material transmission, in particular to a material clamping transmission component. Background Art

[0002] In the prior art, the film clamping and transmission assembly is as described in CN215666267U, and the main roller frame is provided with a pair of main and slave rollers and a pair of auxiliary slave rollers in parallel and with the axis lines coplanar. The auxiliary slave rollers have a smaller diameter than the main and slave rollers and are arranged on the outside of the main and slave rollers, and the pressure roller and the two active rollers are arranged in a herringbone pattern; the transmission belt encloses the main and slave rollers and the auxiliary slave rollers, and the adjustment frame is installed on the outside of the main roller frame; the first and second guide shafts of the adjustment frame adjust the swing angle between the adjustment frame and the adjustment seat along the arc guide groove of the adjustment seat, and the swing angle is fixed by a locking member; the adjustment seat is installed on a pushing cylinder, and the pushing cylinder pushes the transmission belt surface and the pressure roller surface to be close to each other.

[0003] In order to ensure the normal transmission of the film, the film is clamped between the active roller and the driven roller, and the driven roller and the active roller can be pressed tightly together by the cylinders at both ends of the driven roller; when the axial lengths of the active roller and the driven roller are short, the middle section of the driven roller can still ensure the fit with the active roller; but when the axial lengths of the active roller and the driven roller are long, the cylinders at both ends of the driven roller can ensure that the two ends of the driven roller are in fit with the active roller, and the middle section of the driven roller will not be in fit with the active roller due to insufficient downward pressure. Since the film is thin enough, the driven roller and the active roller do not have enough fit, which will cause the film to slip during transmission and the film cannot be transmitted normally.

[0004] Therefore, it is necessary to improve the material clamping and transmission components in the prior art. Utility Model Content

[0023] With this design, the pressing roller 32 abuts against the middle roller surface of the driven roller 2, applying a pressing force to the active roller 1, ensuring that the driven roller 2 is always in close contact with the active roller 1, thereby ensuring the normal transmission of the film.

[0024] Furthermore, at least two groups of the pressing components 3 are provided along the axis direction of the driven roller 2 .
