Description

Biax membrane cutter

Technical Field

The utility model relates to the technical field of electronic equipment protective film processing equipment, in particular to a double-shaft film cutting machine.

Background

The film cutting machine is also called a film cutting machine and is commonly used for cutting the protective films of the front panel and the rear panel of the mobile phone and the tablet personal computer. The film cutting machine solves the application problems and is a non-two choice for small-batch multi-variety die cutting, and the traditional die cutting is different from the traditional die cutting which needs to customize a cutting die according to patterns, wastes time and labor in the aspect of small-batch multi-variety personalized custom die cutting. The film cutting machine adopts a motor to drive a cutting knife, can cut edges of the protective film of the electronic equipment, and cuts the mobile phone film into a standard shape and width. FIG. 1 is a schematic diagram of a prior art film cutter. When the film cutting machine 1 in the prior art is used for cutting films, firstly, the type of the film to be cut is manually selected on the operation panel 13 of the film cutting machine 1, then, one film is manually taken and put on the base 11 of the film cutting machine 1, the film is pressed on the roll shaft 16 of the film cutting machine 1 by the pressing wheel 12, the roll shaft 16 is arranged on the base 11 of the film cutting machine 1, and the film cutting machine 1 is manually started. The roll shaft 16 of the film cutting machine 1 rotates in cooperation with the pressing wheel 12 to move the film, and the cutting part 14 cuts the film. The motor 15 drives the cutting part 14 to move transversely and the roll shaft 16 drives the film to move longitudinally, so that a preset plane pattern is cut on the film. With the film cutter 1 of the prior art, since the portion of the film pressed by the roller 16 and the pressing wheel 12 cannot be cut, a part of the dead zone of each cut film cannot be cut, and in order to leave this part of the dead zone, the area of the film used is larger than the area actually required, resulting in a great amount of waste. On the other hand, insufficient friction force between the roll shaft 16 and the pinch roller 12 on the film causes the film to shift when the cutting portion 14 cuts the film longitudinally, and thus a large cutting error is caused.

The pressing wheel 22 can press the film on the roller shaft 26, and drives the film to move on the base 21 along the Y-axis direction in the drawing by rolling together with the roller shaft 26, and the trolley 25 drives the cutting mechanism 24 to move along the X-axis direction in the drawing, so that a plane pattern is cut on the film. When the film cutting machine is used, the operation panel 23 is clicked, an operation instruction can be sent to the film cutting machine 2, the film cutting machine 2 comprises a control system, and the control system can cut out corresponding patterns according to the content of the instruction.

Referring to fig. 3-4, the film cutting machine 2 of the present utility model includes 2 rollers 26, wherein the 2 rollers 26 are disposed on the base 21 in parallel, a first roller area 261, a second roller area 262 and a third roller area 263 are sequentially disposed on the rollers 26, the film cutting machine 2 further includes 2 roller shafts 29, a first roller 221, a second roller 222 and a third roller 223 are disposed on the roller shafts 29, the first roller 221 presses on the first roller area 261, the second roller 222 presses on the second roller area 262, and a portion of the third roller 223 presses on the third roller area 263, wherein the length of the first roller area 261 is greater than or equal to the length of the first roller 221, the length of the second roller area 262 is greater than or equal to the length of the second roller 226, and the length of the third roller area 263 is less than or equal to the length of the third roller 223. At least one of the two ends of the pinch roller shaft 29 is provided with a spring (not shown) to provide continuous downward pressure to the pinch roller shaft 29, thereby ensuring that the pinch roller shaft 29 and the pinch roller 22 are continuously pressed against the roller shaft 26. The soft material that the outside parcel frictional force is stronger in first roller district 261 and second roller district 262 can effectively protect the membrane that is cut when promoting frictional force, prevents that the surface of membrane from being scraped the flower, and first roller district 261 and second roller district 262 mainly used provide frictional force when cutting the less membrane of size such as cell-phone membrane. Because large-sized films such as plate meninges are easy to generate larger moment in the cutting process, the films are easy to deflect when the cutting mechanism 24 longitudinally cuts, the materials used on the outer side of the third roll shaft area 263 are different from the materials used on the first roll shaft area 261 and the second roll shaft area 262, the outer side of the third roll shaft area 263 is made of hard materials with higher friction force, the third roll shaft area 263 is mainly used for providing stronger friction force when cutting large-sized films such as plate meninges, and the large-sized films are prevented from deflecting due to insufficient friction force when being cut, so that cutting errors are generated. The cutting mechanism 24 is disposed between the two rollers 26, so that it is possible to prevent the problem that the effective cutting area is reduced by the single roller always pressing a part of the film at the time of cutting.

The cutting process is more stable by arranging the trolley motor 27 on the side of the film cutter 2 and driving the trolley 25 and the cutting mechanism 24 via the trolley belt 28. Providing different areas on the roller 26 may create different frictional forces for different sized films, which may be more suitable for cutting different sized films. The length of the first roller shaft region 261 and the second roller shaft region 262 is set to be equal to or longer than the corresponding length of the pressing wheel 22, so that stability in cutting a small-sized film can be ensured, and the length of the third roller shaft region 263 is set to be equal to or shorter than the length of the third pressing wheel 223, so that sufficient friction force can be ensured to be provided by the pressing wheel 22 and the roller shaft 26 in cutting a large-sized film.
