Description

Technical Field

[0001] The utility model relates to the technical field of film edge cutting, and more specifically to a conveniently adjustable film edge cutting device. Background Art

[0002] The film trimming device is a device used to cut and trim the film. During the production and processing, the film usually needs to be cut and trimmed to ensure that its size is accurate and the edge is smooth, suitable for making various products. The existing trimming device cannot adjust the distance between the cutting knives on both sides. When in use, the device can only trim the film of one width, which has high limitations in use.

[0003] After searching, a Chinese patent with announcement number CN215149699U discloses a film trimming device that is easy to adjust the spacing. It is equipped with a motor, a bevel gear, a matching threaded sleeve and a threaded rod. When in use, by starting the motor, the output shaft of the motor rotates to drive the first pulley to rotate, drive the belt on the surface to rotate, and finally drive the threaded rod to rotate, so that the threaded sleeve can move horizontally on the threaded rod, drive the top cutting knife to move relatively, and can control the two cutting knives to move towards or away from each other. During the movement, the cutting spacing can be adjusted, so that the device can trim films of various widths and has better usability.

[0004] When the above-mentioned trimming device is in use, the distance between the two cutting knives needs to be adjusted according to the width of the film, and then the film is trimmed by the cutting knife. However, it is inconvenient to position the film before cutting. When the film and the cutting knife are misaligned, defective products are easily cut out. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a thin film trimming device which is convenient to adjust, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thin film trimming device that is easily adjustable, comprising a mounting frame, the top end of the mounting frame is fixedly connected to a top frame, a first hydraulic cylinder is fixedly installed at the inner center position of the top frame, a cutting assembly is provided at the bottom of the first hydraulic cylinder, the cutting assembly includes a cross plate and a tool body, a limit assembly is provided inside the mounting frame, and the limit assembly includes a screw rod, two T-shaped sliders, two threaded sleeves and two limit plates.

[0007] Furthermore, both ends of the screw rod are fixedly connected to the mounting frame, the two T-shaped sliders and the two threaded sleeves are movably mounted on the screw rod, and the facing sides of the two threaded sleeves are respectively in contact with the two T-shaped sliders, and the bottom ends of the two limit plates are respectively fixedly connected to the two T-shaped sliders.

[0008] Furthermore, a sliding rod is fixedly connected to the interior of the mounting frame, and one end of the sliding rod passes through two T-shaped sliding blocks.

[0009] It can be seen that in the above technical solution, the T-shaped slider slides on the slide rod, which can improve the stability of the limit plate.

[0010] Furthermore, the bottom end of the first hydraulic cylinder is fixedly connected to the transverse plate, and the top end of the tool body is fixedly connected to the transverse plate.

[0011] Furthermore, pressure plates are movably provided on both sides of the tool body, the top ends of the two pressure plates are fixedly connected to two springs, and the top ends of the four springs are fixedly connected to the transverse plate.

[0012] Furthermore, telescopic rods are movably arranged inside the four springs, and the top ends and bottom ends of the four telescopic rods are fixedly connected to the cross plate and the two pressure plates respectively.

[0013] It can be seen that in the above technical solution, the two pressure plates are prevented from deflecting.

[0014] Furthermore, a support plate is movably provided at the bottom of the tool body, a second hydraulic cylinder is fixedly installed at the bottom end of the support plate, and the bottom end of the second hydraulic cylinder is fixedly connected to the mounting frame.

[0015] It can be seen that in the above technical solution, the debris generated by cutting remains on the top of the support plate, the second hydraulic cylinder is started, the piston rod on the second hydraulic cylinder contracts to drive the support plate downward, thereby driving the support plate downward, and then the debris at the bottom of the support plate is cleaned.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model drives the horizontal plate to move downward by extending the piston rod on the first hydraulic cylinder, thereby driving the tool body to move downward, and the film is trimmed by the tool body. Before trimming, the limit plates are moved horizontally toward each other and contacted with the film. The film can be squeezed and positioned by the two limit plates. At the same time, the two limit plates drive the two T-shaped sliders to slide on the screw rod, and then the two threaded sleeves are rotated in turn and contacted with the two T-shaped sliders respectively, so as to limit the two limit plates. The operation is simple and the adjustment is convenient. At the same time, it is convenient to position the film, and it is not easy to cut out defective products.

[0018] 2. Before cutting, the utility model drives four springs to move downward, thereby driving two pressing plates to move downward. The two pressing plates squeeze both sides of the film to prevent the film from deformation and displacement, resulting in uneven cutting and burrs. At the same time, four telescopic rods limit the two pressing plates to prevent the two pressing plates from deflecting when moving vertically. The structure is simple and easy to use.
