Further, the tip of crooked roller is equipped with the pivot, the pivot is equipped with the draw-in groove, the interior card tooth joint of draw-in groove and chuck, the outside of chuck is equipped with outer clamping tooth, outer clamping tooth and screw thread axle threaded connection, the screw thread axle sets up on twist grip, twist grip and fixed bolster are articulated, the fixed bolster sets up on the fixing base.
Further, the middle bulge of the arc shaft is 16 mm higher than the two ends.
Further, the bearings are arranged in a plurality, and the spacing distance is 100-120 mm.
Furthermore, the inner ring of the bearing is fixed on the arc shaft through a clamp spring, and the outer ring of the bearing is embedded in the rubber sleeve or in interference fit with the rubber sleeve, so that the rubber sleeve is fastened on the bearing through the contractibility of the rubber sleeve.
The chuck is driven to rotate through the rotation of the rotating handle, and then the arc-shaped shaft is driven to rotate, so that the inclination angle of the arc-shaped shaft is adjusted, and the required inclination angle is achieved.
The corona machine is internally provided with a silica gel roller, and a high-pressure cutter row is arranged above the silica gel roller and used for corona treatment.
According to the utility model, the radian can be adjusted according to the width of the base film at any time, and the required inclination angle can be changed due to different widths of the base film, so that the bending roller is required to be adjusted according to the width of the base film, and the inclination angle is changed.
When the film path enters the corona machine and passes through the bending roller device, if the surface of the film has a folding condition, the bending effect of the bending roller changes a straight line into an arc line in the horizontal direction, the distance is increased, the contact surface of the film is further increased, the film can be instantly unfolded, and the film is wrinkled and spread, so that the film can smoothly enter the corona machine to carry out corona treatment, the conditions of breakdown and dead folding are solved, and the product yield is greatly improved.
The beneficial effects of the utility model are as follows: the base film is prevented from being folded and the like, and can be smooth and free from the influence of the width of the film.
The utility model is further described below with reference to the drawings and examples.
Drawings
FIG. 1 is a schematic diagram of a film flattening device of a corona machine in accordance with an embodiment of the present utility model;
Fig. 2 is a schematic structural view of an arc shaft according to an embodiment of the present utility model.
Detailed Description
The following description of the preferred embodiments of the present utility model is provided for the purpose of illustration and explanation only and is not intended to limit the present utility model.
Examples
As shown in fig. 1-2, a film flattening device of a corona machine comprises a corona machine 1, wherein a bending roller 2 is arranged at the inlet end of the corona machine, the bending roller 2 is arranged at a position 10cm away from the front end of the corona machine, the bending roller 2 is an arc-shaped shaft 21 with a raised middle height of 16 mm (namely, the middle is 16 mm higher than the two ends), a rubber sleeve is sleeved outside the arc-shaped shaft, and the rubber sleeve is hinged with the arc-shaped shaft through a bearing;
