Description

Technical Field

[0001] This utility model relates to the field of reflective film production and winding technology, and in particular to a reflective film production and winding device that can avoid wrinkles. Background Technology

[0002] Reflective film is a special optical film material widely used in road traffic safety signs, occupational safety clothing, advertising signs and other fields. Its core principle is to reflect incident light back to the light source through the built-in microprism structure or glass microbead structure, thereby forming a conspicuous and clear visual signal at night or in poor lighting conditions. In the production process of reflective film, winding is a key process before finished product processing or semi-finished product transfer. Currently, the main problems encountered in the winding process of reflective film are the formation of wrinkles. If the tension of the film material is uneven or the radial pressure is insufficient during the winding process, the film layers are prone to lateral or longitudinal wrinkles due to relaxation. Once wrinkles are formed, they not only affect the appearance regularity of the film roll, but also cause irreversible indentation, deformation or even breakage of the microprism structure at the wrinkle, which seriously weakens the reflective intensity of the film material in that part, resulting in product downgrading or scrapping. Therefore, developing an automated winding device that effectively prevents wrinkles and ensures neat winding has become an urgent need to improve the quality and production efficiency of reflective film products.

Detailed Implementation

[0018] 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.

[0019] A wrinkle-free reflective film production winding device, such as Figures 1 to 5 As shown, the device includes a bracket 1, a winding assembly mounted on the side of the bracket 1, a winding cylinder 4 mounted on the winding assembly, and an anti-wrinkle assembly mounted on the top outer wall of the bracket 1. The anti-wrinkle assembly includes a vertical plate 6, a pressure roller 8, and a connecting plate 9. The vertical plate 6 is fixed to the top outer wall of the bracket 1 by screws. An elastic element is mounted on the side of the vertical plate 6. The winding column 14 and the connecting plate 9 are fixedly connected. The pressure roller 8 is rotatably connected to the inner wall of the through hole opened on the surface of the connecting plate 9, and a rubber pad 12 is adhered to one side of the outer wall of the pressure roller 8. When it is necessary to wind the reflective film, first install the winding cylinder 4 on the winding assembly. After the winding cylinder 4 is installed, wrap one end of the reflective film around the outer circumference of the winding cylinder 4. In the initial state, the elastic force of the elastic element makes the pressure roller 8 and the surface of the reflective film wrapped around the outer circumference of the winding cylinder 4 press tightly together. When the winding assembly drives the winding cylinder 4 to rotate and wind the reflective film, the elastic force of the elastic element ensures that as the diameter of the winding cylinder 4 with the reflective film gradually increases, the pressure roller 8 is still in close contact with the surface of the wound reflective film, ensuring the tightness of the reflective film wound on the winding cylinder 4 while avoiding wrinkles caused by unevenness on the surface of the reflective film.

[0020] The winding assembly includes a winding motor 2, a contact plate 3, and a winding column 14. The winding motor 2 is fixed to the outer wall of one side of the bracket 1 by screws. The winding column 14 is connected to the output end of the winding motor 2 by a rear coupling. The contact plate 3 is welded to the outer circumference of the winding column 14, and the winding cylinder 4 is installed on the outer circumference of the winding column 14 by a plug-in method. The winding cylinder 4 can be installed using the winding column 14. The contact plate 3 abuts and limits one end of the winding cylinder 4. After the winding cylinder 4 is installed, the winding motor 2 drives the winding column 14 to rotate, so that the winding cylinder 4 winds the reflective film during synchronous rotation.

[0021] One end of the winding column 14 is connected to a locking nut 21 via an external thread; By connecting the locking nut 21 and the end of the winding column 14 with threads, the locking nut 21 presses against the end of the winding drum 4 away from the contact plate 3, ensuring the stability of the winding drum 4 relative to the winding column 14.

[0022] The elastic element includes a spring 7 and a T-shaped rod 13. The T-shaped rod 13 is slidably connected to the inner wall of the through hole on the surface of the upright plate 6. The connecting plate 9 and the T-shaped rod 13 are fixedly connected by screws. The spring 7 is sleeved on the outer wall of the T-shaped rod 13, and the two ends of the spring 7 are respectively fixed to the outer wall of one side of the upright plate 6 and the inner wall of one side of the T-shaped rod 13. The spring force of spring 7 ensures a tight fit between the pressure roller 8 and the reflective film wound on the outer wall of the winding cylinder 4. The longitudinal section of the T-shaped rod 13 is in a shape other than a circle, such as an ellipse or a rectangle, to prevent the T-shaped rod 13 from rotating relative to the upright plate 6. The rubber pad 12 is placed between the pressure roller 8 and the side of the contact plate 3 to reduce the friction between the pressure roller 8 and the contact plate 3 during the rotation of the contact plate 3.

[0023] A lateral limiting assembly is installed on the top outer wall of the bracket 1. The lateral limiting assembly includes a vertical plate 5 and a guide rod 17. The vertical plate 5 is fixed to the top outer wall of the bracket 1 by screws. The guide rod 17 is slidably connected to the inner wall of a through hole on the surface of the vertical plate 5. A plate is installed at one end of the guide rod 17. The plate includes a movable plate 18, a drive plate 19 and a pressure sensor 20. The movable plate 18 is fixed to one end of the guide rod 17 by screws. The pressure sensor 20 is fixed between the movable plate 18 and the drive plate 19. A rubber pad 10 is adhered to the outer surface of the drive plate 19. By setting the contact plate 3, one side of the reflective film can be limited during the winding process. By setting the guide rod 17 to slide along the vertical plate 5, the drive plate 19 and the rubber pad 10 can limit the other side of the reflective film according to the length of the winding cylinder 4, ensuring that the reflective film is aligned with the side of the winding cylinder 4 during the winding process. Specifically, the guide rod 17 is slid along the vertical plate 5 according to the length of the winding cylinder 4, so that the rubber pad 10 and the side of the winding cylinder 4 are in contact with each other. The pressure sensor 20 is used to monitor the pressure on the drive plate 19 and the rubber pad 10 to avoid excessive pressure on the side of the winding cylinder 4, which could cause damage to the winding cylinder 4.

[0024] A self-locking motor 15 is fixed to one side of the outer wall of the vertical plate 5 by screws. The output end of the self-locking motor 15 is connected to a lead screw 16 through a coupling, and a lead screw nut that is compatible with the lead screw 16 is installed on the side of the moving plate 18. The self-locking motor 15 can drive the lead screw 16 to rotate, so that the moving plate 18 can move automatically in the lateral direction under the guidance of the guide rod 17.

[0025] A controller 11 is mounted on the side of the bracket 1; The controller 11 is electrically connected to each electrical component. The controller 11 receives the real-time pressure signal from the pressure sensor 20 and compares it with the preset pressure threshold, thereby controlling the start, stop and direction of the self-locking motor 15. When the pressure is lower than the threshold, the controller 11 controls the self-locking motor 15 to rotate forward and drive the lead screw 16 so that the rubber pad 10 on the drive plate 19 and the side of the winding drum 4 are in contact. When the pressure reaches or exceeds the threshold, the controller 11 controls the self-locking motor 15 to stop, thereby realizing automatic and constant force control of the lateral limit component.

[0026] Working principle: First, the winding motor 2 is started to drive the winding column 14 and the winding drum 4 mounted on it to rotate and start winding the reflective film; the spring 7 continuously applies elastic force to the pressure roller 8, so that the reflective film is always adaptively pressed against the gradually increasing outer surface of the film roll throughout the winding process, effectively flattening and preventing wrinkles. The controller 11 receives the pressure signal detected by the pressure sensor 20 in real time, and controls the self-locking motor 15 to drive the lead screw 16 to precisely adjust the lateral position of the moving plate 18 and the drive plate 19, ensuring that the rubber pad 10 on the drive plate 19 is in contact with the end face of the winding drum 4 with a preset constant pressure.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
