Moreover, the existing film rollers usually have a simple method of fixing the material core or a complicated adjustment process, making it difficult to quickly and reliably tighten and fix and finely adjust the position according to different core sizes or winding requirements, which affects winding quality and ease of operation.

[0003] Therefore, this application provides a slitting machine film roller to meet the requirements. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] refer to Figure 1-4 The slitting machine film roller shown includes a support leg 1 and a bracket 2. The bracket 2 is fixed on the support leg 1. A film roller 3 for winding material is provided above the bracket 2. Both ends of the film roller 3 are connected to the bracket 2 via a mounting frame 4 and a limiting block 6, respectively. A limiting lock 7 for locking the film roller 3 is hinged to the limiting block 6. A drive motor 5 for driving the film roller 3 to rotate is provided on the mounting frame 4. To facilitate material unloading after winding, the mounting frame 4 is rotatably connected to the bracket 2. To make material unloading by the film roller 3 more convenient and faster, the film roller 3 also includes a rotating bearing 31 and a connecting block 3. 2. The outer casing and inner shaft 34 are equipped with a tensioning mechanism 35, which has multiple sets. The outer casing has multiple sets of tensioning holes 33 that are compatible with the tensioning mechanism 35. The bracket 2 below the limiting block 6 is connected to the adjusting bolt 8 for adjusting the film roller 3 via a fixing plate 9, making the winding adjustment of the film roller 3 more convenient and quick. At the same time, in order to facilitate the driving of the film roller 3 and the removal of materials, the rotating bearing 31 and the connecting block 32 are respectively set at both ends of the inner shaft 34. The inner shaft 34 is connected to the output end of the drive motor 5. The outer casing and the inner shaft 34 are slidably connected.

[0022] As one embodiment of this invention, the tensioning mechanism 35 further includes a first guide block 351, a second guide block 352, and a tensioning block 36. The length of the tensioning mechanism 35 is the same as the length of the tensioning hole 33. The first guide block 351 and the second guide block 352 are located between the outer casing and the inner shaft 34. The length of the tensioning block 36 is less than the length of the tensioning hole 33, and the width of the tensioning block 36 is the same as the width of the tensioning hole 33. The tensioning block 36 slides between the first guide block 351 and the second guide block 352. Both the first guide block 351 and the second guide block 352 are bolted together. On shaft 34, the cross-section of tension block 36 is V-shaped, and the top surface of tension block 36 is arc-shaped. Threaded holes 353 are provided on the first guide block 351 and the second guide block 352. Threaded holes for installing tension mechanism 35 are provided on the inner shaft 34. When the inner shaft 34 drives the first guide block 351 and the second guide block 352 to move, one side of the tension block 36, which is tightly fitted between the two, connects with the tension hole 33. When the first guide block 351 and the second guide block 352 continue to move, the tension block 36 extends out of the outer shell through the tension hole 33 to tension and fix the inner core of the material.

[0023] As one embodiment of this invention, in order to make it easier to control the tension of the device, the rotating bearing 31 is connected to the outer shell through the mounting ring 37. The inner diameter of the mounting ring 37 is adapted to the adjusting bolt 8, and the inner diameter of the mounting ring 37 is smaller than that of the inner shaft 34. The fixing plate 9 is provided with bolt holes adapted to the adjusting bolt 8, and the connecting block 32 is provided with a sliding groove adapted to the inner shaft 34. An elastic reset block 321 is provided in the sliding groove.

[0024] The working principle of this utility model is as follows: When using the device, the operator should first assemble the film roller 3. First, insert the inner shaft 34 into the outer casing. Then, install the rotating bearings 31 and connecting blocks 32 at both ends of the film roller 3 onto the outer casing. Next, insert the tensioning mechanism 35 into the tensioning hole 33. Fix the first guide block 351 and the second guide block 352 to the inner shaft 34 using screws. Then, install the film roller 3 onto the output end of the drive motor 5 via the connecting blocks 32. Next, fit the inner core of the material to be wound onto the film roller 3. Then, by rotating the mounting bracket 4, move the rotating bearing 31 on the film roller 3 into the limiting block 6. Then, lock the film roller 3 using the limiting lock 7. After adjusting the inner core of the material on the film roller 3 to the desired position, rotate the adjusting bolt 8 to push the inner shaft 34 towards the elastic reset block 321. When the inner shaft 34 drives the first guide... When block 351 and guide block 352 move, one side of tension block 36, which is tightly fitted between the two, connects with tension hole 33. When the first guide block 351 and the second guide block 352 continue to move, tension block 36 extends out of the outer shell through tension hole 33 to tension and fix the inner core of the material. Then, the slit material can be wound onto the inner core of the material. After that, the drive motor 5 can be started to work with the slitting machine to wind up the slit material. When the material needs to be removed, simply rotate the adjusting bolt 8 in the opposite direction so that the inner shaft 34 is reset under the action of elastic reset block 321. The tension block 36 is retracted by the first guide block 351 and the second guide block 352, and no longer tensions and supports the inner core of the material. Then, the limit lock 7 is unlocked, and the mounting frame 4 can be rotated to make the film roller 3 leave the limit block 6, so that the wound material can be easily taken out.
