Description

A double-layer film superimposed cutting device and method

technical field

The invention belongs to the technical field of film cutting equipment manufacturing, and in particular relates to a double-layer film stacking and cutting device and method.

Background technique

The film slitter is composed of an unwinding mechanism, a cutting mechanism, a winding mechanism, various functional rollers, and a tension control and detection device. Its working principle is: the metallized film raw material released from the unwinding mechanism enters the cutting mechanism through the flattening roller, tension detection roller, empowering roller, and deviation correction system. After the raw material is cut, it is rewound by the winding mechanism into Compliant film rolls.

At present, the film cutting machine can only cut single-layer films. With the development of science and technology, the requirements for films are getting higher and higher. Many technical fields require double-layer films, and the shape of each single-layer film in the double-layer film, Thickness varies. In order to meet the demand, the method of first cutting the single layer and then bonding or riveting is generally adopted, which is laborious and laborious, and often fails to meet the precision requirements.

At present, the pressure roller in the film slitting machine generally adopts a steel roller, which has a large surface hardness and a small friction coefficient. During operation, the tension gradually increases with the increase of the film turntable, resulting in hard streaks and drifting of the film surface. In severe cases, end-face serial membranes are produced.

Contents of the invention

Aiming at the problems that current film slitters cannot be stacked and cut, and hard streaks, film surface drift, and even end-face stringing of films are likely to occur during the lamination process, the present invention proposes a double-layer film stacking and cutting device and method.

A double-layer film stacking and cutting device, the upper part of the frame 1 is provided with a pressing roller 2, the first winding roller 3 and the second winding roller 15 are arranged on both sides of the pressing roller 2, and a knife groove roller 4 is arranged inside the frame 1 , the first guide roller 5 , the second guide roller 16 and the third guide roller 17 , two pressing rollers 6 are arranged outside the frame 1 , and a stacker 7 is arranged outside the pressing rollers 6 .

The outer surface of the pressure roller 2 is provided with a flexible layer 8 .

The flexible layer 8 is made of rubber material.

The two pressing rollers 6 are vertically arranged, and the gap between them is 0.01mm-2mm.

The structure of the stacker 7 is as follows: the upper guide plate 10 and the lower guide plate 11 are set in the stacking frame 9, the upper guide plate 10 and the lower guide plate 11 are arranged in parallel, and the upper guide plate 10 and the lower guide plate 11 are respectively provided with a Moved card bar 12 .

The working process of the double-layer film stacking and cutting device: the film is guided and stacked by the film parent roll through the stacker, pressed by the pressing roller, guided by the second guide roller and the third guide roller, then cut by the knife groove roller, and then passed through The first guide roller guides to the cylinder surface of the pressure roller, and then winds onto the first winding roller and the second winding roller.

Beneficial effects of the present invention: the double-layer film stacking and cutting device of the present invention can uniformly press and cut films with different thicknesses and widths according to a predetermined pattern, and a flexible layer is provided on the outer surface of the pressing roller, which avoids the film pressing process There are problems such as hard streaks, drift of the film surface, and even series of films on the end face.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example 1

A double-layer film stacking and cutting device, as shown in Figure 1, the upper part of the frame 1 is provided with a pressure roller 2, the two sides of the pressure roller 2 are provided with a first winding roller 3 and a second winding roller 15, and the frame 1 A sipe roller 4, a first guide roller 5, a second guide roller 16 and a third guide roller 17 are arranged inside, two pressing rollers 6 are arranged outside the frame 1, and a stacker 7 is arranged outside the pressing roller 6. A flexible layer 8 is provided on the outer surface of the pressure roller 2 . The flexible layer 8 is made of rubber material. The flexible layer can increase the coefficient of surface friction and prevent hard streaks on the surface of the film. The two pressing rollers 6 are vertically arranged with a gap of 0.01 mm to 2 mm.

As shown in Figure 2, the structure of the stacker 7 is as follows: the upper guide plate 10 and the lower guide plate 11 are arranged in the stacking frame 9, the upper guide plate 10 and the lower guide plate 11 are arranged in parallel, and the upper guide plate 10 and the lower guide plate 11 are arranged in parallel. Each is provided with movable card bar 12.

The working process of the double-layer film stacking and cutting device in this embodiment: the film 14 is guided and stacked by the film parent roll through the stacker 7 through 13, pressed by the pressing roller 6, guided by the second guide roller 16 and the third guide roller 17, Then it is divided by the knife groove roller 4 , then guided to the cylinder surface of the pressure roller 2 through the first guide roller 5 , and then wound onto the first winding roller 3 and the second winding roller 15 .

The distance between the upper guide plate 10 and the lower guide plate 11 on the stacker 7 is adjustable to adjust the angle at which the film enters, and the distance between the two clamping bars 12 on the upper guide plate 10 and the lower guide plate 11 respectively Adjustable to determine the width of the film. After the films are stacked by the stacker 7, the laminated double-layer film is uniform, and there will be no uneven width of the laminated film.
