Description

Technical Field

[0001] This utility model relates to the field of pre-coated film production technology, and specifically discloses a pre-coated film slitting device applicable to multiple specifications. Background Technology

[0002] In the field of pre-coated film processing, pre-coated film, as a functional material widely used in printing, packaging, and lamination industries, directly affects the quality and cost of subsequent processes due to its slitting accuracy and efficiency. Currently, most pre-coated film slitting devices on the market employ a fixed blade holder structure, where the blade spacing and position are determined during equipment manufacturing, making it difficult to adjust flexibly according to actual production needs. Therefore, such devices are typically only suitable for slitting pre-coated film of a single specification (such as a specific width).

[0003] When processing pre-coated films of different widths, operators often need to stop the machine to change the cutting tools or reassemble the tool holder. This is not only time-consuming and labor-intensive, reducing production efficiency, but also prone to dimensional deviations due to human error, affecting product consistency. Furthermore, in small-batch, multi-variety order production, frequent tool changes accelerate equipment wear and increase maintenance costs. In addition, the pre-coated film may deform during cutting, further affecting the cutting effect. Utility Model Content

[0004] The purpose of this invention is to provide a pre-coated film slitting device applicable to multiple specifications, which can adapt to the slitting requirements of various specifications of pre-coated films, and at the same time can limit the pre-coated film to avoid deformation during the cutting process and affect the cutting effect.

[0005] This utility model is achieved through the following technical solution: A pre-coated film slitting device applicable to multiple specifications includes a base, with limiting mechanisms at both ends of the base, a lifting seat at the top center of the base, a cylinder between the base and the lifting seat, two sliding seats and a driving mechanism for driving the sliding seats to move on the lifting seat, and a cutting mechanism at the bottom of the sliding seats.

[0006] Furthermore, the limiting mechanism includes mounting seats on both sides of the base, a rotating shaft rotatably mounted on the inner side of the mounting seats, and a motor fixedly mounted on the outer side of the mounting seats. The rotating shaft located on the inner side of the mounting seats has swing arms at both ends, and a limiting roller is provided between the two swing arms. The output end of the motor is connected to the rotating shaft.

[0007] Furthermore, the two ends of the limiting roller are respectively rotatably connected to two swing arms, and the swing arms are fixedly connected to the rotating shaft.

[0008] Furthermore, the drive mechanism includes a through slot formed in the lifting seat, a guide rod installed in the through slot, a slide rail installed on the top of the lifting seat, a movable seat adapted to the slide rail, and a second cylinder connected to the movable seat. The sliding seat is slidably connected to the guide rod, and the two sliding seats are respectively hinged to the movable seat.

[0009] Furthermore, a connecting rod one is provided on the top of the sliding seat, and a connecting rod two is provided on the top of the movable seat. The connecting rod one and the connecting rod two are hinged together by a connecting plate.

[0010] Furthermore, the through groove is provided with a plurality of parallel guide rods, and each guide rod is respectively inserted into the sliding seat.

[0011] Furthermore, the cutting mechanism includes an L-shaped mounting plate disposed at the bottom of the sliding seat, a second motor is fixedly mounted on the L-shaped mounting plate, and a cutting blade is connected to the output end of the second motor.

[0012] Furthermore, a total of four cylinders are provided, and the four cylinders are arranged in a rectangular shape.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: In this invention, a driving mechanism moves two sliding seats closer together or further apart, thereby adjusting the distance between the two sliding seats and indirectly adjusting the distance between the two cutting mechanisms, thus cutting pre-coated films of different widths. Furthermore, a limiting mechanism positions the inlet and outlet ends of the pre-coated film, preventing deformation of the pre-coated film during cutting and ensuring optimal cutting results. This slitting device enhances equipment versatility and production flexibility, meeting the current market's urgent demand for efficient and low-cost processing. Attached Figure Description

[0021] Example 1 Reference Figures 1-4 This embodiment provides a pre-coated film slitting device applicable to multiple specifications, including a base 1. Limiting mechanisms are provided at both ends of the base 1. A lifting seat 2 is provided above the middle of the base 1. A cylinder 20 is provided between the base 1 and the lifting seat 2. A total of four cylinders 20 are provided, and the four cylinders 20 are distributed in a rectangular shape. Two sliding seats 3 and a driving mechanism for driving the sliding seats 3 are provided on the lifting seat 2. A cutting mechanism is provided at the bottom of the sliding seats 3.

[0022] In this embodiment, the limiting mechanism includes mounting seats 4 disposed on both sides of the base 1, a rotating shaft 5 rotatably mounted inside the mounting seats 4, and a motor 8 fixedly mounted on the outside of the mounting seats 4. Swing arms 6 are provided at both ends of the rotating shaft 5 located inside the mounting seats 4, and limiting rollers 7 are provided between the two swing arms 6. The output end of the motor 8 is connected to the rotating shaft 5. The two ends of the limiting rollers 7 are rotatably connected to the two swing arms 6 respectively, and the swing arms 6 are fixedly connected to the rotating shaft 5. The mounting seats 4 can be integrally formed with the base 1. A cylinder 20 is fixedly mounted on the top of the mounting seats 4, and the drive end of the cylinder 20 is fixedly connected to the lifting seat 2. It should be noted that conveying guide rollers are also provided at the front and rear ends of the base 1. The front conveying guide roller is used for feeding, and the rear conveying guide roller mainly functions to pull away the narrow-width pre-coated film after it has been cut. In use, motor 8 drives the rotating shaft 5 to rotate, which in turn drives the swing arm 6 to rotate, so that the limiting roller 7 on the swing arm 6 presses on the surface of the pre-coated film to limit the pre-coated film and prevent the edge of the pre-coated film from deforming during the conveying process, which would affect the cutting. It can also unfold the pre-coated film to avoid wrinkles affecting the cutting. At the same time, it can limit the pre-coated film of different thicknesses, and has a wide range of applications.

[0023] In this embodiment, the driving mechanism includes a through slot 9 formed in the lifting seat 2, a guide rod 10 installed in the through slot 9, a slide rail 11 installed on the top of the lifting seat 2, a movable seat 12 adapted to the slide rail 11, and a second cylinder 13 connected to the movable seat 12. The sliding seat 3 is slidably connected to the guide rod 10, and the two sliding seats 3 are respectively hinged to the movable seat 12. A connecting rod 14 is provided on the top of the sliding seat 3, and a connecting rod 15 is provided on the top of the movable seat 12. The connecting rod 14 and the connecting rod 15 are hinged together by a connecting plate 16. A plurality of parallel guide rods 10 are provided in the through slot 9, and each guide rod 10 passes through the sliding seat 3. A fixed seat is provided on the side wall of the lifting seat 2, and the second cylinder 13 is installed on the top of the fixed seat. The driving end of the second cylinder 13 is fixedly connected to the movable seat 12. In use, cylinder 13 drives the movable seat 12 to move on the slide rail 11, causing the connecting plate 16 to rotate around the connecting rod 15. This causes the connecting plate 16 to drive the connecting rod 14 to move, which in turn moves the sliding seat 3. This allows for adjustment of the distance between the two sliding seats 3, so as to obtain pre-coated films of different widths. The variable pitch structure achieved by cylinder 13 is simple and easy to operate.

[0024] Reference Figures 3-4 The cutting mechanism includes an L-shaped mounting plate 17 disposed at the bottom of the sliding seat 3. A second motor 18 is fixedly mounted on the L-shaped mounting plate 17, and a cutting blade 19 is connected to the output end of the second motor 18. The L-shaped mounting plate 17 is welded or bolted to the sliding seat 3. A cutting groove 21 is formed on the surface of the base 1, located directly below the cutting blade 19, to facilitate the cutting of the pre-coated film by the cutting blade 19. In use, a cylinder 20 drives the lifting seat 2 to rise and fall, thereby adjusting the height of the cutting mechanism to facilitate the cutting of pre-coated films of different thicknesses. When the cutting blade 19 descends to the cutting groove 21, the second motor 18 drives the cutting blade 19 to rotate, thereby slitting the pre-coated film.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
