Description

Technical Field

[0001] This utility model relates to the technical field of packaging film processing equipment, and in particular to a slitting device for processing packaging film. Background Technology

[0002] In the production and processing of packaging films, slitting is a crucial step. Different specifications of packaging films often require different slitting equipment, which not only increases equipment costs for companies but also reduces production efficiency. To solve this problem, a slitting device capable of adjusting the roller spacing is needed to accommodate packaging films of varying thicknesses and widths.

[0003] Existing packaging film slitting equipment suffers from significant differences in thickness and width among various types of packaging films. Lacking adjustable roller spacing, the equipment can only process specific film specifications, failing to effectively slit other sizes. This severely limits its application, potentially requiring companies to purchase multiple slitting machines of different specifications, increasing costs and space requirements. Therefore, we propose a packaging film slitting equipment to address this problem. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4 A slitting device for processing packaging film includes: a base plate 1; a fixed plate 10, a fixed frame 4, a winding device 2, and an unwinding device 3 are fixedly installed on the top of the base plate 1; four sets of limiting rods 23 are fixedly installed inside the fixed frame 4; two sets of movable plates 20 are slidably installed on the outer sides of the four sets of limiting rods 23; a cutting blade 21 and a cutting table 22 are fixedly installed on opposite sides of the two sets of movable plates 20; two sets of bidirectional lead screws 5 and two sets of guide rods 11 are rotatably installed on the top of the fixed plate 10; and two sets of movable plates 21 are threadedly connected to the outer sides of the two sets of bidirectional lead screws 5. Block 6 has guide rods 11 slidably mounted on the outer side of two sets of guide rods 11. Rotating shafts 9 are rotatably mounted inside both sets of moving blocks 6. Rollers 15 are fixedly mounted on the outer side of both sets of rotating shafts 9. Top plates 8 are fixedly mounted on the top of both sets of guide rods 11. Two sets of bidirectional lead screws 5 are rotatably mounted inside the top plate 8. Bevel gears 13 are fixedly mounted on the top of both sets of bidirectional lead screws 5. Brackets 14 are fixedly mounted on the top of the top plate 8. Rotating rods 24 are rotatably mounted inside both sets of brackets 14. Two sets of bevel gears 12 are fixedly mounted on the outer side of rotating rods 24.

[0016] In this embodiment, rotating plates 17 are rotatably installed on both inner walls of the fixed frame 4. Two sets of mounting seats 19 are fixedly installed on both sides of the two sets of moving plates 20. The two sets of mounting seats 19 on the same side are hinged to the corresponding rotating plates 17 with connecting rods 18. A second motor 16 is fixedly installed on one side of the fixed frame 4. One set of rotating plates 17 is fixedly installed on the output end of the second motor 16, which can efficiently transmit the power of the motor to the rotating plates 17, reducing the loss of power in the transmission process. This direct drive method makes the equipment more stable and reliable during operation, can quickly respond to the motor's commands, and improve the working efficiency of the equipment.

[0017] In this embodiment, a motor 7 is fixedly installed on the top of one of the brackets 14, and the rotating rod 24 is rotatably installed on the output end of the motor 7. This eliminates the need to replace different slitting devices for packaging films of different thicknesses, reducing the time required for equipment adjustment and replacement, thereby improving production efficiency.

[0018] In this embodiment, each of the two sets of moving blocks 6 has two sets of sliding holes inside, and two sets of guide rods 11 are slidably installed in the corresponding sliding holes. The cooperation between the guide rods 11 and the sliding holes provides clear directional guidance for the movement of the moving blocks 6. During the operation of the equipment, the moving blocks 6 need to move relative to each other to adjust the distance between the rollers 15. The guide rods 11 ensure that the moving blocks 6 move along a predetermined straight trajectory, avoiding deviation, shaking or twisting during the movement.

[0019] In this embodiment, the two sets of bevel gears 12 mesh with the corresponding bevel gears 13. Since the transmission of bevel gears can be achieved in a small space, the footprint of the equipment can be reduced. This is very important for some production environments with limited space, and can improve the installation flexibility and adaptability of the equipment.

[0020] In this embodiment, two sets of fixing blocks are fixedly installed on both sides of the two sets of moving plates 20. The four sets of fixing blocks are slidably installed on the outside of the corresponding limiting rods 23. The limiting rods 23 provide a clear moving track for the fixing blocks, ensuring that the moving plates 20 always move along the predetermined direction during the movement process without deviation, shaking or twisting. This is crucial for the cutting operation of the packaging film, ensuring accurate alignment between the cutting blade 21 and the cutting table 22, and improving cutting accuracy and quality.

[0021] In this embodiment, during use, the packaging film is placed inside two sets of rollers 15. The motor 7 is started, driving the rotating rod 24 to rotate, which in turn drives the bevel gear 12 to rotate, which in turn drives the bevel gear 13 to rotate simultaneously. This drives the bidirectional lead screw 5 to rotate, which in turn drives the moving block 6 to move relative to the guide rod 11. This allows adjustment of the two sets of rollers 15 to accommodate packaging films of different thicknesses. One end of the packaging film outside the unwinding device 3 is placed inside the winding device 2. Starting the winding device 2 winds up the packaging film. This eliminates the need to change to different slitting devices for different thicknesses of packaging film, reducing equipment adjustment and replacement time, thereby improving production efficiency. This is particularly useful for large-scale production. During the production of packaging film, different thicknesses of packaging film can be quickly switched for slitting to meet market demand for different specifications of packaging film. After winding, the rotating plate 17 is driven to rotate by the starting motor 16. Then, the mounting base 19 and the moving plate 20 are moved relative to each other by the support rod under the restriction of the limiting rod 23. Then, the two sets of moving plates 20 drive the cutting blade 21 and the cutting table 22 to cut the packaging film, thereby realizing the slitting of the packaging film. This process realizes automated cutting, eliminating the need for manual operation of the cutting blades, greatly improving production efficiency. In large-scale packaging film processing and production, the cutting task can be completed quickly and accurately, meeting the needs of high-efficiency production.
