Description

Technical Field

[0001] The utility model relates to the field of film cutting machines with a limiting function, in particular to a film cutting machine with a limiting function. Background Art

[0002] Film is a thin, soft, transparent sheet, usually made of plastic, adhesive, rubber or other materials. When film is used, it is usually necessary to use a film cutter to cut the film roll into film sheets of a size suitable for the purpose, so as to facilitate subsequent processing;

[0003] For example, a film cutting machine with a limiting function disclosed in the utility model with the authorization announcement number CN220362626U includes a base, a die-cutting machine frame is installed on the top of the base, a limiting seat is installed on the top of the base, and a third movable plate is installed inside the limiting seat, and a first electric push rod is installed on the top of the limiting seat. The utility model can facilitate the upward movement of the third movable plate by installing and starting the first electric push rod, and the third movable plate drives the inner side of the second movable plate to tilt upward through the fourth movable plate, and the second movable plate drives the bottom of the mounting seat to tilt outward, and the mounting seat drives the outer side of the limiting plate to tilt upward through the hinge action, so that the inner side of the limiting plate is pressed down to clamp the plastic template, and the limiting plates are provided with four groups, which can effectively limit the periphery of the cutting, so as to prevent the die-cutting machine blade from easily deviating or wrinkling due to its light weight during the cutting process, and the film cannot be flat and fixed, resulting in the film size being different after the final cutting. First, when the device is cutting the film, after replacing the die-cutting machine blade, the plastic film to be cut is placed on the top of the limit seat, and then the first electric push rod is started. The third movable plate drives the inner side of the second movable plate to tilt upward through the fourth movable plate, and the second movable plate drives the bottom of the mounting seat to tilt outward. The mounting seat drives the outer side of the limit plate to tilt upward through the hinge action, so that the inner side of the limit plate presses down to clamp the plastic film and effectively limit the periphery of the cutting. The device is not provided with a film conveying component, so that the cutting of the film requires manual conveying, which makes the cutting work continuity poor and the cutting efficiency low.

A left-right symmetrical pressure roller 17 is set inside the lifting frame 16, and a third motor 20 is connected to the rear end of the pressure roller 17 on the left side. Pulleys are installed at the rear ends of the two pressure rollers 17, and the pulleys are connected by a belt transmission. Symmetrical limit rods 18 are formed on the front and rear side panels of the film cutting machine frame 1, and the limit rods 18 penetrate the lifting frame 16 upward. The two are independent of each other. The setting of the limit rod 18 prevents the position of the lifting frame 16 from shifting, and a support leg 2 is formed at the diagonal portion of the lower surface of the film cutting machine frame 1;

[0022] When cutting the film, the first telescopic cylinder 7 extends to drive the clamping block 9 to slide downward in the clamping slot 8, and the cutting knife 10 follows the sliding to cut the film. When conveying the film, the film is placed flat on the conveyor belt 4, and the third telescopic cylinder 19 is controlled to contract to drive the lifting frame 16 to descend. The lifting frame 16 moves relative to the position of the limit rod 18 until the pressure roller 17 presses the film, and the pressure roller 17 is driven to rotate by the rotation of the third motor 20;

[0023] like Figure 1 - Figure 5 As shown, the film cutting machine frame 1 is U-shaped as a whole, and two left-right symmetrical conveying rollers 3 are mounted on the film cutting machine frame 1, and a conveying belt 4 is arranged on the conveying rollers 3. The rear ends of the two conveying rollers 3 are installed with pulleys, and the pulleys are connected by a belt transmission. The rear end of the conveying roller 3 on the left is connected to a first motor 5, and the first motor 5 is arranged on the rear side of the film cutting machine frame 1. A material discharge slope 11 with a cutting groove is formed on the left inner wall of the film cutting machine frame 1, and a through-hole is provided on the plate body of the film cutting machine frame 1 on the left side of the material discharge slope 11. The groove 13 is provided with a lifting drive assembly, which includes a limit roller 12, a second telescopic cylinder 14, and a second motor 15. Two second telescopic cylinders 14 are embedded in the left plate of the film cutting machine frame 1, which are symmetrical in front and back.

When the film is conveyed to the unloading slope 11, the film is passed from under the limiting roller 12, and at the same time, the second telescopic cylinder 14 is controlled to extend to drive the limiting roller 12 to move downward in the passing groove 13 to press the film. When it is conveyed to a suitable length, all motors can be controlled to stop moving, and then the first telescopic cylinder 7 is controlled to extend to drive the card block 9 to slide downward in the card slot 8, and the cutting knife 10 follows the sliding, and the cutting knife 10 cuts the film, and then the motor continues to run. In the cutting process, the film port after the cut is not easy to enter under the limiting roller 12. After completing one cutting, the first telescopic cylinder 7 can be controlled to complete a lifting, which is convenient for pressing and limiting the film, so that the film remains tight and the cutting quality is guaranteed.

[0025] Specific working principle:

[0026] When using the device, the film is placed flatly on the conveyor belt 4, the third telescopic cylinder 19 is controlled to contract to drive the lifting frame 16 to descend, and the lifting frame 16 moves relative to the position of the limit rod 18 until the pressure roller 17 presses the film, and the pressure roller 17 is driven to rotate by the third motor 20, and the first motor 5 drives the conveying roller 3 to rotate, so that the conveyor belt 4 and the pressure roller 17 move at the same time, and the film is transported to the unloading slope 11. When the film is transported to the unloading slope 11, the film is passed from under the limit roller 12, and at the same time, the second telescopic cylinder 14 is controlled to extend to drive the limit roller 12 to move downward in the passing groove 13 to press the film. When the film is transported to a suitable length, all motors can be controlled to stop moving.
