Description

Technical Field

[0001] This utility model relates to the field of packaging and printing, and more specifically, to a release film roll fixing mechanism. Background Technology

[0002] The release film winding and fixing mechanism is a device used to fix the winding drum for winding and fixing the release film. The release film winding and fixing mechanism is widely used in various occasions that require the winding of release film, such as packaging material production, electronic product manufacturing and other fields.

[0003] The take-up drum is placed between the fixed rod and the adjusting rod. By adjusting the position of the adjusting rod, the roller is brought into close contact with the take-up drum. The take-up equipment is started, and the take-up drum begins to rotate, thereby winding the release film onto the take-up drum.

[0004] Existing release film winding drums generally adopt external fixing methods. In actual operation, due to the application of uneven external force or pressure exceeding the bearing capacity, the entire device will be severely deformed, which will seriously affect the accuracy, stability and long-term reliability of release film winding. Therefore, there is an urgent need for a new type of release film winding drum fixing mechanism. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a release film winding and fixing mechanism to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A release film winding fixing mechanism includes a worktable with support plates opposite each other on the worktable. An optical shaft is connected between the support plates, and a disc is fixedly sleeved on the optical shaft. A circular groove is formed on the inner wall of the center of the disc, and an electric turntable is arranged in the circular groove. Several arc protrusions are formed on the outer periphery of the electric turntable. Several first through holes corresponding to the arc protrusions are formed on the inner wall of the disc. A sliding shaft is slidably connected in the first through holes. A fixed plate is fixed to one end of the sliding shaft away from the disc, and the other end of the sliding shaft abuts against the arc protrusions. This mechanism solves the problem that existing release film winding mechanisms, which generally use external fixing, can cause serious deformation of the entire device during actual operation due to uneven external forces or pressures exceeding the bearing capacity.

[0008] Furthermore, the fixing plate has an arc-shaped structure, which better fits the shape of the inner wall of the winding drum. The outer side of the fixing plate is provided with anti-slip rubber to further increase friction and improve the fixing effect.

[0009] Furthermore, the electric turntable is integrally formed with the arc protrusion, and a first groove is provided between adjacent arc protrusions to avoid unnecessary interference between components during movement.

[0010] Furthermore, a second groove is provided inside the disc, and a coiled spring is provided inside the second groove. A second through hole is provided on the sliding shaft, and the coiled springs all pass through the second through hole. This allows the sliding shaft to apply greater pressure when fixing the winding drum, thereby enhancing the fixing effect and preventing the winding drum from loosening or falling off during rotation.

[0011] Furthermore, baffles are provided on both the support plate and the fixed plate on the optical axis to prevent the release film from accidentally detaching from the take-up drum.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) This solution ensures that the winding drum is subjected to a uniformly distributed force during the fixing process by setting an electric turntable to cooperate with the arc protrusion and sliding adjustment of the sliding shaft in the first through hole, thereby avoiding device deformation caused by non-uniform external force.

[0014] (2) By setting the coiled spring in the second groove and the second through hole on the sliding shaft, the fixing effect is enhanced, preventing the winding drum from loosening or falling off during rotation. Attached Figure Description

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A release film take-up cylinder fixing mechanism, with a support plate 2 set relative to the worktable 1, serves to stably support the optical shaft 5, ensuring that the optical shaft 5 remains in a horizontal and fixed position. A disc 3 is fixedly sleeved on the optical shaft 5, and a circular groove 10 is formed on the inner wall of the center of the disc 3. An electric turntable 4 is installed in the circular groove 10, and several arc protrusions 6 are provided on the outer periphery of the electric turntable 4. When the electric turntable 4 rotates, the arc protrusions 6 can orderly push the sliding shaft 8 that is in contact with it. Several first through holes 7 are formed on the inner wall of the disc 3, providing a track for the sliding shaft 8 to slide in a directional manner, ensuring that the sliding shaft 8 only... It can move in a predetermined direction. The end of the sliding shaft 8 away from the disk 3 is fixedly connected to a fixing plate 9. The arc-shaped fixing plate 9 and the anti-slip rubber 16 on the outside can better fit the inner wall of the take-up drum, avoiding random shaking or misalignment. This allows the fixing plate 9 to fix the inner wall of the release film take-up drum tightly and stably, ensuring that the take-up drum always maintains the correct position and does not shift or tilt during the entire winding process. This solves the problem that the existing release film take-up drums generally use external fixing methods, which can cause serious deformation of the entire device in actual operation due to the application of non-uniform external force or pressure exceeding the bearing capacity.

[0023] Please see Figure 2 The disc 3 has a second groove 12, and a coiled spring 13 is provided in the second groove 12. The sliding shaft 8 has a second through hole 14, and the coiled spring 13 passes through the second through hole 14. The coiled spring 13 enables the sliding shaft 8 to apply greater pressure when fixing the winding drum, which enhances the fixing effect and prevents the winding drum from loosening or falling off during rotation.

[0024] The working principle is as follows:

[0025] When it is necessary to fix the release film take-up drum, the electric turntable 4 is started. The electric turntable 4 begins to rotate around the optical axis 5. Since the electric turntable 4 and the arc protrusion 6 are integrally formed, the arc protrusion 6 also rotates synchronously as the electric turntable 4 rotates. During the rotation, the arc protrusion 6 will abut against the sliding shaft 8 in contact with it, pushing the sliding shaft 8 to slide outward along the first through hole 7 on the disc 3, that is, away from the center of the disc 3. When the sliding shaft 8 slides outward, it drives the fixing plate 9 fixed at its end to move synchronously. Multiple fixing plates 9 gradually approach the take-up drum under the drive of their respective sliding shafts 8. Because the fixing plate 9 has an arc-shaped structure and is provided with anti-slip rubber 10 on the outside, it can fit well against the inner wall of the take-up drum. The anti-slip rubber 10 increases the friction, thereby fixing the take-up drum from multiple directions. This solves the problem that the existing release film take-up drum generally adopts an external fixing method, which can cause serious deformation of the entire device in actual operation due to the application of non-uniform external force or pressure exceeding the bearing capacity.

[0026] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
