Technical Field

The invention relates to the technical field of film blowing machines, in particular to a traction rotating gear mechanism on a film blowing machine.

Background

The thickness of each point of the cylindrical film bubble extruded from the die head of the blow molding machine is difficult to be absolutely uniform, and the thickness deviation belongs to systematic errors, namely if the film bubble extruded from a certain point in the circumferential direction of the circular ring-shaped die opening is thicker, the subsequent film bubble is continuously thicker at the position, otherwise, if the film bubble extruded from a certain point in the circumferential direction of the circular ring-shaped die opening is thinner, the subsequent film bubble is continuously thinner at the point, and therefore, the thick and thin points of the film rolled in the traditional mode are gradually accumulated and superposed at the same position of the coiled material, so that the thickness of the rolled film roll is seriously nonuniform, rib bursting occurs, and the rolling quality is poor.

In order to overcome the defects, a rotary traction device is designed, so that the traction clamping roller rotates around the central axis of the circular die, namely the traction clamping roller rotates relative to the central axis of the film bubble, the thick and thin points of the film are in a wave distribution state in the axial direction of the coiled material after the film is flattened and wound, and are dispersed in the axial direction of the coiled material, so that the thick and thin points of the film are uniformly distributed in the axial direction of the coiled material and cannot be accumulated at the same position, and therefore the problem of error accumulation caused by systematic errors of the thickness is well solved, and the winding quality is improved.

Most of the rotary traction devices on the market at present have complex internal structures, influence the traction efficiency of films, are easy to damage and difficult to maintain, and have poor user experience, so that a rotary traction gear mechanism on a film blowing machine is needed to be developed.
