Description

Technical Field

[0001] This utility model relates to the field of aluminum foil cutting technology, specifically an aluminum foil cutting machine with adjustable width. Background Technology

[0002] Aluminum foil paper refers to paper made by bonding aluminum foil backing paper and aluminum foil together. It is soft, easily deformed, and does not spring back after deformation. It has good light-blocking properties and is commonly used in decorative packaging, food packaging, and cigarette packaging. After aluminum foil paper is produced, it usually needs to be cut into smaller rolls using a slitting knife. For example, Chinese patent CN217894559U discloses a slitting device for producing aluminum foil paper, including a base and a worktable. Side plates are provided on the front and rear sides of the upper surface of the base. A front support plate is provided on the upper surface of one side of each side plate. A feeding roller is provided on the upper part of the front support plate. A tensioning mechanism is provided below the front support plate. A first fixing block is provided on the right side of the front support plate.

[0003] The aforementioned patent effectively prevents aluminum foil from wrinkling or breaking due to insufficient tension by setting a tensioning mechanism after the feeding roller. The flattening mechanism reduces waste caused by wrinkled aluminum foil or product movement during operation, significantly reducing costs, improving efficiency, and lowering labor intensity. However, this patent cannot cut aluminum foil into different widths according to user needs. Existing aluminum foil cutting devices require manual adjustment of the cutting blade position when cutting to different widths, which is inconvenient for devices with multiple cutting blades, and the adjustment accuracy is low, making it unsuitable for use. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum foil cutting machine with adjustable width to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-width aluminum foil cutting machine includes a base. A drive roller and a driven roller are mounted on the upper end of the base. A cutting table is disposed between the drive roller and the driven roller. A gantry frame is fixedly mounted on the upper end of the cutting table. Two electric telescopic rods are fixedly mounted on the upper end of the gantry frame. A U-shaped frame is fixedly mounted on the telescopic end of each electric telescopic rod. A geared motor is fixedly mounted on one end of the U-shaped frame. A transmission screw is fixedly connected to the output end of the geared motor. A screw nut is mounted on the transmission screw. A first adjusting mounting seat is fixedly mounted on the outer side of each screw nut. Multiple second adjusting mounting seats are slidably disposed on the transmission screw at one end of the first adjusting mounting seat. An electric circular cutter is mounted on the bottom end of each of the first and second adjusting mounting seats.

[0007] In a preferred embodiment, a slider is fixedly provided at the top of the first and second adjusting mounting seats. The slider is slidably disposed in a slide groove, which is formed on the side wall of the U-shaped frame. The slider and slide groove make the adjusting mounting seats more stable when moving and also prevent the adjusting mounting seats from rotating with the transmission screw.

[0008] In a preferred embodiment, a first connecting rod is rotatably provided on the rear side of both the first and second adjusting mounting seats. Adjacent first connecting rods are rotatably connected by a pin. When the transmission screw rotates, multiple adjusting mounting seats can move under the action of multiple first connecting rods, thereby causing the adjusting mounting seats to drive the electric circular cutter to move.

[0009] In a preferred embodiment, a second connecting rod is hinged to both sides of the first and second adjusting mounting bases. The bottom end of the second connecting rod is hinged to the bracket. A roller is rotatably mounted on the inner side of the bracket. When cutting aluminum foil, the roller first contacts the aluminum foil. Under the tension of the aluminum foil, the roller moves outward, which can prevent the aluminum foil from wrinkling during cutting.

[0010] In a preferred embodiment, a spring is provided on the inner side of the second link, and the end of the spring away from the second link is fixedly mounted on the outer side wall of the electric circular cutter. The spring allows the roller to adapt to changes.

[0011] In a preferred embodiment, a cutting groove is provided on the upper surface of the cutting table, and the cutting groove is located directly below the electric circular cutter. The cutting groove can prevent the electric circular cutter from making hard contact with the cutting table.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a structure including a geared motor, an adjusting mounting base, a transmission screw, a connecting rod, and a pin, utilizes the geared motor to drive the transmission screw to rotate. When the transmission screw rotates, it enables the first adjusting mounting base to move in the horizontal direction. When the first adjusting mounting base moves, it can drive multiple second adjusting mounting bases to move under the action of multiple connecting rods, so that the distance between the first adjusting mounting base and the multiple second adjusting mounting bases remains consistent, achieving equidistant adjustment of the electric circular cutter. It is not only convenient to operate, but also has higher precision than manually adjusting multiple electric circular cutters sequentially.

[0014] 2. This utility model, by setting a second connecting rod, roller, spring and other structures, when the electric circular cutter presses down, the roller first contacts the aluminum foil, and under the tension of the aluminum foil, the roller extends outward, which can unfold the aluminum foil outward and prevent wrinkles from occurring at the cutting position.
