Description

Technical Field

[0001] This utility model relates to the field of oxygen barrier film production, and in particular to a slitting device for the production of agricultural oxygen barrier film. Background Technology

[0002] The agricultural oxygen barrier film production slitting device is a special equipment designed for high-barrier films in the agricultural field. Its core function is to cut wide rolls of film into narrow finished films according to a preset width using a high-precision knife set. It is mainly used for agricultural mulch films, greenhouse covering films, etc.

[0003] For example, CN215660505U discloses a film slitting device for film production, including two symmetrically arranged vertical plates. A first rolling roller is rotatably connected between the opposing sidewalls of the two vertical plates via a connecting shaft. Two U-shaped mounting slots are opened at the top, and slitting components are installed in the two U-shaped mounting slots. A motor, shaft-connected to the first rolling roller, is fixedly connected to the sidewall of one of the vertical plates. A drive gear disposed on the side of the vertical plate is shaft-connected to the end of the first rolling roller away from the motor. This utility model relates to the field of film production technology. This utility model solves the problem that film slitting cutters used in film production are usually fixedly mounted on the rolling roller, making it inconvenient or even impossible to adjust the distance between the slitting cutters, thus preventing the slitting of films with different slitting widths.

[0004] In the existing technology, the position of the slitting blade is adjusted by moving the mounting ring, and the motor runs. The first roller drives the second gear on one side of the first gear to rotate under the operation of the motor, so that the slitting blade can slit the oxygen barrier film. However, the thickness of the oxygen barrier film is different, and the slitting blade will also wear out after long-term use, making it impossible for the slitting blade to accurately and completely slit the oxygen barrier film. Secondary processing is required, which reduces the slitting efficiency and the pass rate. Utility Model Content

[0024] Please see Figure 2 and Figure 3The slitting assembly includes mounting rings 141, multiple mounting rings 141 are slidably connected to the outer wall of the second roller 12, a moving block 142 is fixedly connected to the inner wall of the mounting ring 141, and the moving block 142 is slidably connected to the adjusting groove 13. A slitting blade 143 is fixedly connected to the outer wall of the mounting ring 141. The drive assembly includes a motor 2 and a first gear 21. The motor 2 is fixedly connected to one end of the fixed frame 1, and the transmission shaft on one side of the motor 2 is fixedly connected to the first roller 11. The first gear 21 is fixedly connected to the end of the first roller 11 away from the motor 2. A second gear 22 is meshed with the outer wall of the first gear 21, and the second gear 22 is fixedly connected to the second roller 12.

[0025] In this embodiment, the bolts on the mounting ring 141 are removed according to the slitting requirements. The mounting ring 141 is held and moved. The moving block 142 fixed at the bottom of the mounting ring 141 slides in the adjusting groove 13 under the movement of the mounting ring 141, adjusting the position of the slitting blade 143. The motor 2 is turned on, and the transmission shaft connected to one side of the motor 2 drives the first roller 11 and the first gear 21 at one end of the first roller 11 to rotate under the operation of the motor 2. The second gear 22 drives the second roller 12 to rotate under the rotation of the first gear 21. The slitting blade 143 cuts the oxygen barrier membrane as the second roller 12 rotates.

[0026] Please see Figure 3 and Figure 4 The mounting ring 141 is fixedly connected to both ends of the mounting ring 5. The connecting component includes a support frame 31, which is fixedly connected to one end of the placement platform 3 near the fixed frame 1. The top of the support frame 31 is provided with a sliding groove 32. The cutting component includes a slide 41, and multiple slides 41 are slidably connected inside the sliding groove 32. The bottom end of the slide 41 is fixedly connected to a slide 41. A connecting frame 42 is fixedly connected to the side of the slide 41 near the fixed ring 5, and the connecting frame 42 is slidably connected to the fixed ring 5.

[0027] In this embodiment, the connecting frame 42 connected to the fixed ring 5 moves with the movement of the mounting ring 141, causing the connecting frame 4 to move. The slide 41 slides on the slide groove 32 as the connecting frame 4 moves, so that the cutting blade 433 and the slitting blade 143 are at the same horizontal line. When the slitting blade 143 cuts the oxygen barrier membrane, the connecting frame 42 slides on the fixed ring 5, so that the position of the cutting blade 433 remains unchanged. The oxygen barrier membrane cut by the slitting blade 143 is transported to the placement table 3 for placement.

The cutting blade 433 is held and pushed, and the connecting block 432 is moved out of the mounting block 431 as the cutting blade 433 is pushed, which makes it easy to replace the cutting blade 433.

[0030] Working principle: First, according to the cutting requirements, the bolts on the mounting ring 141 are removed, the mounting ring 141 is held and moved, and the moving block 142 fixed at the bottom of the mounting ring 141 slides in the adjusting groove 13 under the movement of the mounting ring 141, adjusting the position of the cutting blade 143. The connecting frame 42 connected to the fixing ring 5 moves with the movement of the mounting ring 141, driving the connecting frame 4 to move. The slide 41 slides on the sliding groove 32 with the movement of the connecting frame 4, so that the cutting blade 433 and the cutting blade 143 are at the same horizontal line.

[0031] Next, the motor 2 starts running. The transmission shaft connected to one side of the motor 2 drives the first roller 11 and the first gear 21 at one end of the first roller 11 to rotate under the operation of the motor 2. The second gear 22 drives the second roller 12 to rotate under the rotation of the first gear 21. The slitting blade 143 cuts the oxygen barrier membrane as the second roller 12 rotates.
