Drawings

The present invention will be further explained with reference to the accompanying drawings

Fig. 1 is a schematic structural view of the cutting device of the present invention;

Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

example 1

As shown in fig. 1, a PVB film cutting device includes a strip-shaped cutting table 100, a winding roll frame is disposed at one end of the cutting table 100 in the length direction, a rolled PVB film 400 is disposed on the winding roll frame, and a cutting area is disposed on the cutting table 100 plane beside the winding roll frame.

The roller frame comprises two vertical supports 501, a roller shaft 502 and a guide shaft 503. The two vertical supports 501 are arranged in the width direction of the cutting table 100 at a certain distance, and the vertical supports 501 are perpendicular to the upper surface of the cutting table 100. A winding roller shaft 502 is arranged between the two vertical supports 501, the rolled PVB film 400 is arranged on the winding roller shaft 502, and a guide shaft 503 is arranged between the two vertical supports 501, and the guide shaft 503 is positioned below the winding roller shaft 502 and is parallel to the winding roller shaft 502. The PVB film on the take-up roll shaft 502 extends around a guide shaft 503 and toward the cutting zone.

The cutting area is provided with a cutting mechanism, the cutting mechanism comprises a flattening piece and a cutting piece, the flattening piece comprises two first track grooves 110 which are parallel to each other and extend along the length direction of the cutting table 100, a pressing strip 201 is arranged between the two first track grooves 110, a sliding block is arranged at the position, corresponding to the first track groove 110, of the pressing strip 201, the sliding block is located in the first track groove 110, and therefore the pressing strip 201 can move back and forth along the first track groove 110. The middle part of the pressing bar 201 is fixedly connected with the telescopic arm of the first hydraulic cylinder 200. Thus, the bead 201 can move along the first rail groove 110 by the first hydraulic cylinder 200.

The cutting member includes a second rail groove 120 disposed outside one of the first rail grooves 110, and the second rail groove 120 is parallel to the first rail groove 110. A cutting slider 302 is disposed in the second track groove 120, and the cutting slider 302 can slide in the second track groove 120. A second hydraulic cylinder 301 is arranged on one side of the cutting slider 302, and a telescopic arm of the second hydraulic cylinder 301 passes through the cutting slider 302 and extends to a position between the two first track grooves 110. The end of the telescopic arm of the second hydraulic cylinder 301 is fixed with a cutting block 303, and the lower surface of the cutting block 303 is provided with a rotatable cutter.

When the device is cutting the operation, tiling behind the PVB membrane 400 winds from guiding axis 503 is at the upper surface of cutting platform 100, then first hydraulic cylinder 200 drive layering 201 removes, will wait that the PVB membrane 400 of cutting flattens, then according to the position that needs the cutting, adjusts the angle and the position of cutter, carries out horizontal or vertical cutting.

The cutting device has the advantages of good cutting linearity and high speed, and can be quickly adjusted to realize quick cutting of PVB films of different specifications.

Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept.
