Description
Technical Field
[0001] This utility model relates to the field of film winding technology, and in particular to a film winding mechanism. Background Technology
[0002] Thin film materials refer to thin metal or organic layers with a thickness ranging from a single atom to several millimeters. They are usually made of plastics, adhesives, rubber, or other materials. After production, the film needs to be wound up. For example, announcement number CN219448669U relates to a film auxiliary winding mechanism, which includes a worktable. A main material roller is rotatably mounted on the top of the worktable, and a winding roller is mounted on one side of the main material roller. An auxiliary roller assembly is provided between the main material roller and the winding roller. The main material roller, the winding roller, and the auxiliary roller assembly are all connected to the top of the worktable via support rods. The rotating shafts of the main material roller and the winding roller are fixedly connected to the output shaft of a motor. A cleaning component is provided on the surface of the auxiliary roller assembly. This utility model utilizes the worktable, allowing the main material roller, the winding roller, and the auxiliary roller assembly to be mounted on the surface of the worktable via support rods. The main material roller and the winding roller can be rotated by a motor to wind up the film. The auxiliary roller assembly and the cleaning component allow the film surface to be cleaned during winding. The contraction of the auxiliary roller assembly facilitates the limiting of the film, which can improve the winding efficiency of the film to a certain extent.
[0003] However, existing technologies have some problems: when the equipment is in use, the height of its auxiliary roller is fixed. Although the auxiliary roller can tighten the film and prevent wrinkles during the film winding process, the height of the auxiliary roller cannot be adjusted, so the tension force on the film winding cannot be adjusted. As the diameter of the film on the winding roller increases, the tension force is easily too large, which may cause the film to be stretched and deformed, reducing the winding quality. Therefore, we propose a film winding mechanism. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a film winding mechanism that, by incorporating an adjustable-height auxiliary roller, facilitates the adjustment of tension as needed, thereby maintaining a good winding effect.
[0005] The purpose of this utility model is achieved as follows: A film winding mechanism includes a base with a square groove. Two sliders are movably installed inside the square groove. A vertical plate and a hydraulic cylinder are respectively fixedly installed on the top of the two sliders. A drive motor is fixedly installed on the vertical plate. The output shaft of the drive motor is connected to a rotating shaft through a coupling. A fixed frame is fixedly installed on the top of the base. A guide roller is rotatably connected to the fixed frame. A frame located between the square groove and the fixed frame is fixedly installed on the base. A round shaft is rotatably connected to the frame. Connecting rods are fixedly sleeved on both sides of the outer surface of the round shaft. An auxiliary roller is fixedly installed between the two connecting rods. The round shaft and the frame are also connected by a rotating assembly, which can adjust the height of the auxiliary roller.
[0006] Optionally, the rotating assembly includes a brake motor, which is fixedly mounted on the top of the frame. The output shaft of the brake motor is connected to a rotating shaft via a coupling. The bottom of the rotating shaft passes through the frame and is fixedly connected to a first bevel gear. A second bevel gear is fixedly sleeved on the outer surface of the round shaft, and the second bevel gear is meshed with the first bevel gear.
[0007] Optionally, both sides of the outer surface of the auxiliary roller are movably fitted with stop blocks, and both sides of the top of the auxiliary roller are provided with circular grooves. A pin is movably inserted into the stop block, one end of the pin extends into the circular groove, and the other end of the pin is fixedly connected to a pull handle.
[0008] Optionally, a spring is movably sleeved on the outer surface of the pin, and the two ends of the spring are respectively fixedly connected to the stop block and the pull handle.
[0009] Optionally, the number of hydraulic cylinders is two, and a top plate is fixedly connected between the telescopic ends of the two hydraulic cylinders. The top plate is movably connected to the rotating shaft.
[0010] Optionally, a servo motor is fixedly installed on the base, and the output shaft of the servo motor is connected to a bidirectional lead screw through a coupling. The other end of the bidirectional lead screw extends into the square groove, and the two sliders are respectively threaded onto both sides of the outer surface of the bidirectional lead screw.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention, by setting up a round shaft, connecting rod, auxiliary roller, and rotating assembly, allows the film to be wound onto a take-up roller mounted on a rotating shaft after passing through the bottom of the auxiliary roller. When the operator needs to adjust the height of the auxiliary roller to reduce the tension, the rotating assembly can be used to rotate the round shaft, which in turn causes the connecting rod to rotate the auxiliary roller, thereby adjusting the height of the auxiliary roller and thus achieving tension adjustment to meet different take-up needs. This avoids excessive tension that could cause the film to be stretched and deformed, thus improving the take-up quality. Attached Figure Description

[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] like Figures 1 to 5As shown in the figure, the film winding mechanism provided in this embodiment of the present invention includes a base 1, a square groove 2 on the base 1, two sliders 3 are movably installed inside the square groove 2, a vertical plate 4 and a hydraulic cylinder 5 are respectively fixedly installed on the top of the two sliders 3, a drive motor 6 is fixedly installed on the vertical plate 4, and the output shaft of the drive motor 6 is connected to a rotating shaft 7 through a coupling. A fixed frame 8 is fixedly installed on the top of the base 1, and a guide roller 9 is rotatably connected to the fixed frame 8. A frame 10 located between the square groove 2 and the fixed frame 8 is fixedly installed on the base 1, and a round shaft 11 is rotatably connected to the frame 10. Connecting rods 12 are fixedly sleeved on both sides of the outer surface of the round shaft 11, and an auxiliary roller 13 is fixedly installed between the two connecting rods 12. The round shaft 11 and the frame 10 are also connected by a rotating assembly, which can adjust the height of the auxiliary roller 13.
[0022] Furthermore, the rotating assembly includes a brake motor 14, which is fixedly mounted on the top of the frame 10. The output shaft of the brake motor 14 is connected to a rotating shaft 15 via a coupling. The bottom of the rotating shaft 15 passes through the frame 10 and is fixedly connected to a first bevel gear 16. A second bevel gear 17 is fixedly sleeved on the outer surface of the round shaft 11, and the second bevel gear 17 is meshed with the first bevel gear 16.
[0023] By activating the brake motor 14, the rotating shaft 15 drives the first bevel gear 16 to rotate, which in turn drives the second bevel gear 17 to rotate the round shaft 11, which in turn drives the connecting rod 12 to rotate the auxiliary roller 13. This allows the height of the auxiliary roller 13 to be adjusted to meet different tension requirements during film winding and ensure the winding quality of the film.
[0024] Furthermore, both sides of the outer surface of the auxiliary roller 13 are movably fitted with stop blocks 18, and both sides of the top of the auxiliary roller 13 are provided with circular grooves 19. A pin 20 is movably inserted into the stop block 18, one end of the pin 20 extends into the inside of the circular groove 19, and the other end of the pin 20 is fixedly connected to a pull handle 21.
[0025] By moving the two stops 18 to the appropriate position and then inserting the pin 20 into the circular groove 19 to limit the stops 18, the distance between the two stops 18 can be adjusted, making it easier to center and roll up films of different widths.
[0026] Furthermore, a spring 22 is movably sleeved on the outer surface of the pin 20, and the two ends of the spring 22 are respectively fixedly connected to the stop block 18 and the pull handle 21.
[0027] By setting the spring 22 to a stretched state, due to the restoring effect of the spring 22, the pin 20 will tend to move into the circular groove 19, thereby keeping one end of the pin 20 stably inside the circular groove 19, and thus stably maintaining the limiting effect on the stop block 18.
[0028] Furthermore, there are two hydraulic cylinders 5, and a top plate 25 is fixedly connected between the telescopic ends of the two hydraulic cylinders 5. The top plate 25 is movably connected to the rotating shaft 7.
[0029] The top plate 25 provides good support for the rotating shaft 7. After the winding roller on the rotating shaft 7 has finished winding, the operator can activate the hydraulic cylinder 5 to move the top plate 25 downward, which makes it easier to remove the winding roller on the rotating shaft 7.
[0030] Furthermore, a servo motor 23 is fixedly installed on the base 1. The output shaft of the servo motor 23 is connected to a bidirectional lead screw 24 through a coupling. The other end of the bidirectional lead screw 24 extends into the square groove 2. Two sliders 3 are respectively threaded onto both sides of the outer surface of the bidirectional lead screw 24.
[0031] By starting the servo motor 23, the bidirectional lead screw 24 is rotated, which enables the two sliders 3 to move towards or away from each other, adjusting the distance between the top plate 25 and the vertical plate 4. This allows for the installation of take-up rollers of different lengths on the rotating shaft 7 to take up films of different widths.
[0032] Working principle and usage process of this utility model:
[0033] First, the operator attaches the take-up roller to the rotating shaft 7. Then, the hydraulic cylinder 5 is activated to make the top plate 25 abut against the rotating shaft 7. Subsequently, the servo motor 23 is activated to rotate the bidirectional lead screw 24, which causes the two sliders 3 to move towards each other, so that the upright plate 4 and the top plate 25 contact the two sides of the take-up roller. Then, the position of the stop block 18 is adjusted as needed and the stop block 18 is limited by the pin 20. Then, the film is fixed to the take-up roller through the surfaces of the guide roller 9 and the auxiliary roller 13, and the winding work can be carried out. The drive motor 6 is activated to make the rotating shaft 7 drive the take-up roller to rotate and wind the film. When the operator needs to adjust the height of the auxiliary roller 13 to adjust the tension, the brake motor 14 is activated to make the rotating shaft 15 drive the first bevel tooth 16 to rotate, which in turn makes the second bevel tooth 17 drive the round shaft 11 to rotate, which in turn makes the connecting rod 12 drive the auxiliary roller 13 to rotate, thereby adjusting the height of the auxiliary roller 13 to meet different tension requirements during film winding and ensure the winding quality of the film.
[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
