[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0019] Please refer to Figures 1-4The figure shows an auxiliary tooling for protective film production, including a roller body 1, the roller body 1 is rotatably connected to a protective component 2, the protective component 2 includes a base 3, a rotating shaft 4 is arranged inside the base 3, the rotating shaft 4 is rotatably connected to a group of lower brackets 5 symmetrical with the central axis, a group of lower brackets 5 are fixedly connected to an upper bracket 6, a plurality of groups of sliding blocks 7 are arranged inside the lower bracket 5 and the upper bracket 6, a plurality of groups of sliding blocks 7 are arranged inside the plurality of sliding blocks 7, a roller 8 is arranged inside the plurality of sliding blocks 7, a protective plate 9 is arranged on one side of the sliding block 7, and the protective plate 9 is frictionally connected to the surface of the roller body 1. The utility model connects the protective component through the roller body rotation, the protective component includes a base, a rotating shaft is installed inside the base, the rotating shaft is rotatably connected to the lower bracket, the lower bracket is fixedly connected to the upper bracket, a plurality of groups of sliding blocks are arranged inside the lower bracket and the upper bracket, a roller is arranged inside the sliding block, a protective plate is arranged on one side of the roller, and the protective plate is tightly frictionally connected to the surface of the roller body, without the need for the roller to be grooved, the width of the protective film can be adjusted, and at the same time, it can be adjusted according to different roller specifications.

[0020] Furthermore, a plurality of groups of mutually parallel connecting blocks 10 are provided on one side of the lower bracket 5 and the upper bracket 6, each group of connecting blocks 10 is provided with two sliding rods 11, and a second rotating shaft 12 is provided symmetrically between the two sliding rods 11. By adding a plurality of groups of mutually parallel connecting blocks on one side of the lower bracket and the upper bracket, the influence of the roller body on the sliding block can be effectively reduced, so that the sliding block can be fine-tuned when necessary, thereby improving the stability and flexibility of the equipment.

[0021] Furthermore, the second rotating shaft 12 is threadedly connected to the sliding block 7, and three connecting ears 703 are provided on the outer side of the sliding block 7. The connecting ears 703 on both sides of the outer side of the sliding block 7 are slidably connected to the sliding rod 11, and the connecting ear 703 in the middle of the sliding block 7 is threadedly connected to the second rotating shaft 12. By rotating the second rotating shaft, the position of the sliding block can be precisely controlled to meet different production needs. Three connecting ears are designed on the outer side of the sliding block, and the connecting ears are respectively connected to the sliding rod and the second rotating shaft, allowing the sliding block to move freely on the sliding rod while maintaining stable support.

[0022] Furthermore, a sliding rod 2 701 is provided inside the sliding block 7, and a spring 702 is provided outside the sliding rod 2 701. One end of the spring 702 is tightly pressed against the protective plate 9. The sliding rod 2 provided inside the sliding block allows the protective plate to slide smoothly inside the sliding block, thereby ensuring that the protective plate can fit tightly against the surface of the roller body, which not only enhances the stability of the overall structure, but also effectively avoids the need to open a sliding groove on the roller body.

[0023] Further, one side of the protective plate 9 close to the surface of the roller body 1 is arc-shaped. The protective plate 9 is slidably connected to the sliding block 7 through the second sliding rod 701 and the spring 702. By designing one side of the protective plate close to the surface of the roller body to be arc-shaped, the protective plate can better fit the curved surface of the roller body, thus effectively reducing the gap between the two.

[0024] Further, multiple groups of sliding blocks 7 are slidably connected inside the lower bracket 5 and the upper bracket 6 through the sliding rod 11, the second rotating shaft 12 and in cooperation with the connecting block 10. Through the delicate cooperation of the sliding rod, the second rotating shaft and the connecting block for multiple groups of sliding blocks, the sliding connection inside the lower bracket and the upper bracket is realized, ensuring the linearity and accuracy of the sliding. At the same time, the existence of the second rotating shaft enables the sliding block to flexibly adjust the angle during the sliding process to meet the requirements of different positions.

[0025] In this solution, the working process is as follows: First, the rotating shaft is rotatably connected to a group of lower brackets that are axially symmetric. Then, the lower brackets are fixedly connected to the upper brackets. Before installing multiple groups of sliding blocks inside the lower brackets and the upper brackets, the protective plate is first slidably connected to the sliding block through the second sliding rod and the spring. After that, each assembled group of sliding blocks is provided with a roller.

[0026] Next, multiple groups of parallel connecting blocks are installed on one side of the lower bracket and the upper bracket. Each group of connecting blocks is provided with two sliding rods. At the symmetric positions of the two sliding rods, we provide a second rotating shaft, which is threadedly connected to the sliding block. Three connecting ears are provided on the outer side of the sliding block. Among them, the two outer connecting ears are slidably connected to the sliding rods, while the middle connecting ear is threadedly connected to the second rotating shaft. Such a design enables the sliding block to slide stably inside the lower bracket and the upper bracket.
