Description

Technical Field

[0001] This utility model relates to the field of laser film production technology, and in particular to a device for improving the laser effect on the surface of a laser film. Background Technology

[0002] As a material widely used in packaging, decoration and other fields, the laser effect on the surface of laser film is the core factor that determines the quality and visual appeal of products. The presentation of the laser effect mainly depends on the reflection and refraction of light by the concave and convex structure of the film surface. When light shines on the surface of the laser film, the concave and convex textures of different depths and distributions will produce optical phenomena such as diffuse reflection and directional reflection, thus presenting rich color changes and three-dimensional patterns.

[0003] In existing technologies, the laser effect of laser films is usually achieved through a molding process. A molding plate with specific patterns is used to imprint the patterns onto the film surface under the action of heat and pressure, forming a concave-convex structure.

[0004] In traditional laser film presses, the pressing depth between the molding plate and the film is often fixed during the molding process. This is because the worktable supporting the laser film is mostly a rigid structure, which cannot flexibly change the degree of stress deformation during pressing according to the needs. For the same pattern design, the depth of the concave and convex surfaces formed on the laser film is always consistent. Since the reflection law of light on the concave and convex structures at the same depth is fixed, the final laser effect is often relatively simple and difficult to meet diverse visual needs. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: traditional laser film presses, due to the fact that the worktable supporting the laser film is mostly a rigid structure, cannot flexibly change the degree of stress deformation during pressing, resulting in a fixed pressing depth between the molding plate and the film. Therefore, this invention proposes a device to improve the laser effect on the surface of the laser film.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for improving the laser effect on a laser film surface includes a platform. A laser film press is fixedly mounted on the upper surface of the platform. A slide groove is formed on the upper surface of the platform, and a slide plate is slidably disposed in the slide groove. A rectangular frame is fixedly mounted on the lower surface of the slide plate by multiple telescopic springs. An installation groove is formed on the surface of the platform, and a first threaded rod is vertically and rotatably mounted in the installation groove. A slider is threaded onto the first threaded rod. Vertical rods are symmetrically and vertically fixedly mounted on the upper surface of the slider. The top wall of the installation groove has symmetrical openings that communicate with the slide groove. The top ends of two vertical rods pass through two openings respectively and are fixedly mounted with connecting plates. Both connecting plates are fixedly connected to the rectangular frame. The molding plate of the laser film press corresponds to the position of the slide plate. The rotation of the first threaded rod is controlled by a transmission component. The upper surface of the platform is symmetrically fixed with baffles, and the lower surfaces of the two baffles abut against the upper surface of the slide plate. A rectangular opening is provided on the surface of the platform, and a winding assembly for winding the laser film is provided inside the rectangular opening.

[0007] Preferably, the transmission component includes a worm gear fixedly sleeved on the first threaded rod and a worm shaft horizontally rotatably mounted in the mounting groove, wherein the worm shaft is meshed with the worm gear.

[0008] Preferably, a groove cover is rotatably mounted at the groove opening of the mounting groove via a rotating shaft, and a magnetic strip is fixedly mounted on the groove wall at the groove opening of the mounting groove. The groove cover is made of magnetic material, and the magnetic strip is located on the moving path of the groove cover.

[0009] Preferably, the winding assembly includes a fixed plate vertically fixedly installed on the rectangular opening wall, a rotating shaft horizontally rotatably installed on the surface of the fixed plate, a winding roller fixedly sleeved on the rotating shaft, and a movable plate. The rectangular opening wall has a horizontally opened rotating groove, and a second threaded rod is horizontally rotatably installed in the rotating groove. An L-shaped sliding plate is threadedly sleeved on the second threaded rod. The sliding plate is fixedly connected to the movable plate. The surface of the movable plate has a circular groove for one end of the rotating shaft to be inserted. The rotating shaft is controlled to rotate by a driving component.

[0010] Preferably, the driving component includes a stepper motor fixedly mounted on the surface of the fixed plate, wherein the output shaft of the stepper motor passes through the fixed plate and is fixedly connected to one end of the rotating shaft.

[0011] Preferably, a turntable is fixedly sleeved on the second threaded rod, and the surface of the turntable is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the linkage structure of the first threaded rod, slider, vertical rod and rectangular frame, the initial extension degree of the telescopic spring can be precisely adjusted, thereby controlling the downward movement distance of the slide plate. When the molding plate presses the laser film, the elastic deformation capability of the telescopic spring under the slide plate changes with the adjustment, so that the surface of the laser film forms a concave-convex structure of different depths. Combined with the principle of light reflection, the concave-convex textures of different depths can produce a variety of diffuse reflection effects, which solves the problem of the same concave-convex depth and single presentation effect in traditional devices, and meets diverse visual needs.

[0015] 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.

[0016] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0017] Reference Figures 1-4A device for improving the laser effect on the surface of a laser film includes a platform 1. A laser film press 2 (disclosed in patent publication CN214164373U, entitled "A Film Press for Laser Film Production") is fixedly mounted on the upper surface of the platform 1. This is prior art and its working principle will not be described in detail here. A groove 3 is formed on the upper surface of the platform 1, and a sliding plate 4 is slidably disposed within the groove 3. A rectangular frame 24 is fixedly mounted on the lower surface of the sliding plate 4 via multiple telescopic springs 5. The elastic coefficient of the telescopic springs 5 ​​is adapted to the laser film. The pressure range of the press 2 is as follows: the surface of the platform 1 is provided with an installation groove, in which a first threaded rod 6 is vertically and rotatably installed. A slider 7 is threaded onto the first threaded rod 6. Vertical rods 8 are symmetrically and vertically fixedly installed on the upper surface of the slider 7. The top wall of the installation groove is symmetrically provided with openings that communicate with the slide groove 3. The tops of the two vertical rods 8 pass through the two openings respectively and are fixedly installed with connecting plates 9. Both connecting plates 9 are fixedly connected to the rectangular frame 24. The molding plate of the laser film press 2 corresponds to the position of the slide plate 4. The rotation of the first threaded rod 6 is controlled by a transmission component.

[0018] Reference Figure 2 The upper surface of the platform 1 is symmetrically fixed with baffles 10. The lower surfaces of the two baffles 10 abut against the upper surface of the slide plate 4. The baffles 10 are used to restrict the slide plate 4 from moving out of the slide groove 3. A rectangular opening is provided on the surface of the platform 1, and a winding component for winding up the laser film is provided inside the rectangular opening.

[0019] First, connect one end of the laser film to be pressed to the winding assembly inside the rectangular opening of the platform 1, ensuring that the laser film can be conveyed with the movement of the winding assembly. Start the winding assembly, which operates in an intermittent winding mode, gradually pulling the laser film to move so that the laser film gradually enters the internal space of the laser film press 2. When the part of the laser film that needs to be pressed is precisely moved to the corresponding area between the molding plate and the slide plate 4 of the laser film press 2, the winding assembly stops moving, completing the alignment of the laser film and preparing for pressing.

[0020] Before the molding plate moves down to perform the pressing action, the depth of the laser film pressing can be adjusted as needed. By operating the transmission component, the first threaded rod 6 in the mounting groove is controlled to rotate. Since the slider 7 is threaded onto the first threaded rod 6, and the vertical rod 8 is sequentially fixedly connected to the slider 7, the connecting plate 9 and the rectangular frame 24, the slider 7 will be displaced along the vertical direction of the first threaded rod 6 when the first threaded rod 6 rotates.

[0021] When the slider 7 moves upward, it pushes the connecting plate 9 to move upward synchronously through the two vertical rods 8, which in turn drives the rectangular frame 24 to move upward. At this time, the multiple telescopic springs 5 ​​between the rectangular frame 24 and the slide plate 4 are compressed, and the initial elastic potential energy of the springs increases. In this state, when the molding plate is pressed down, the slide plate 4 needs to overcome a greater spring force to move downward, which reduces the downward movement distance of the slide plate 4 and ultimately makes the unevenness and depth formed on the surface of the laser film shallower.

[0022] Conversely, when the slider 7 moves downward, the vertical rod 8 and the connecting plate 9 drive the rectangular frame 24 to move downward synchronously, and the telescopic spring 5 extends accordingly. The initial elastic potential energy of the spring decreases. At this time, when the molding plate presses down, the sliding plate 4 only needs to overcome a small spring force to produce a large displacement, which deepens the unevenness formed on the surface of the laser film.

[0023] Therefore, by adjusting the initial extension degree of the telescopic spring 5, the distance that the slide plate 4 can move downward can be changed when the subsequent molding plate is pressed down, thus ultimately achieving the adjustment of the concave-convex depth after the laser film is pressed.

[0024] After the pressing depth is adjusted, the molding plate of the laser film press 2 is moved down. The molding plate presses down to contact the laser film and applies continuous force to make the bottom of the laser film make close contact with the upper surface of the slide plate 4 to complete the pressing action. The texture of the molding plate is used to press the corresponding laser effect on the surface of the laser film. Due to the previous adjustment, laser films of the same batch or different batches can obtain laser effects with different concave and convex depths.

[0025] After a single pressing is completed, the winding assembly starts again, pulling the laser film to move and conveying the next section to be pressed to between the molding plate and the slide plate 4. The above alignment and pressing process is repeated to continuously complete the batch processing of the laser film. The winding assembly simultaneously winds up and organizes the pressed laser film.

[0026] Reference Figure 6 The transmission components include a worm gear 11 fixedly sleeved on the first threaded rod 6 and a worm 12 horizontally rotatably installed in the mounting groove, with the worm 12 meshing with the worm gear 11.

[0027] During operation, rotating the worm 12 drives the first threaded rod 6 to rotate through the meshing transmission between the worm wheel 11 and the worm 12, causing the slider 7 to move up and down to adjust the extension and retraction of the telescopic spring 5, thereby controlling the pressing depth. This structure utilizes the deceleration characteristics of the worm wheel 11 and the worm 12 to achieve fine adjustment. The self-locking function ensures that the position is stable after adjustment, and it is labor-saving and easy to operate, accurately guaranteeing the laser effect of different concave and convex depths.

[0028] Reference Figure 6A groove cover 13 is rotatably installed at the groove opening via a rotating shaft. A magnetic strip 14 is fixedly installed on the groove wall at the groove opening. The groove cover 13 is made of magnetic material, and the magnetic strip 14 is located on the moving path of the groove cover 13.

[0029] The slot cover 13 is rotatably installed at the opening of the mounting slot via a rotating shaft. It can rotate around the rotating shaft to open and close the opening of the mounting slot. A magnetic strip 14 is fixedly installed on the wall of the mounting slot. Because the slot cover 13 is made of magnetic material and the magnetic strip 14 is located on the moving path of the slot cover 13, when the slot cover 13 is rotated to the closed state, it will attract each other with the magnetic strip 14, thereby firmly sealing the mounting slot. When it needs to be opened, an external force can be applied to make the slot cover 13 detach from the magnetic strip 14 and rotate around the rotating shaft to open. The slot cover 13 is mainly used to protect the first threaded rod 6, worm gear 11 and worm 12 and other structures located in the mounting slot, so as to prevent the opening of the mounting slot from being in an open state and foreign objects from easily entering the mounting slot.

[0030] Reference Figure 5 and Figure 7 The winding assembly includes a fixed plate 15 vertically fixedly mounted on the rectangular opening wall, a rotating shaft 16 horizontally rotatably mounted on the surface of the fixed plate 15, a winding roller 17 fixedly sleeved on the rotating shaft 16, and a moving plate 18. The rectangular opening wall has a horizontally opened rotating groove, in which a second threaded rod 19 is horizontally rotatably mounted. An L-shaped sliding plate 20 is threadedly sleeved on the second threaded rod 19. The sliding plate 20 is fixedly connected to the moving plate 18. The surface of the moving plate 18 has a circular groove 21 for one end of the rotating shaft 16 to be inserted. The rotating shaft 16 is controlled to rotate by a driving component. The driving component includes a stepper motor 22 fixedly mounted on the surface of the fixed plate 15. The output shaft of the stepper motor 22 passes through the fixed plate 15 and is fixedly connected to one end of the rotating shaft 16. A toggle wheel 23 is fixedly sleeved on the second threaded rod 19. The surface of the toggle wheel 23 is provided with anti-slip texture.

[0031] When performing laser film pressing, the stepper motor 22 rotates intermittently according to a preset program, driving the take-up roller 17 to rotate synchronously through the rotating shaft 16, and winding up the pressed laser film. The precise control of the stepper motor 22 can ensure that the distance of the laser film is consistent each time, so that the area to be pressed is accurately aligned between the molding plate and the slide plate 4, realizing continuous batch processing.

[0032] When it is necessary to pick up, put down, or replace the laser film roll, the second threaded rod 19 can be rotated clockwise by turning the anti-slip textured dial wheel 23. This causes the L-shaped sliding plate 20 to move the moving plate 18 away from the fixed plate 15 until the circular groove 21 of the moving plate 18 is completely disengaged from the free end of the rotating shaft 16. After the distance between the moving plate 18 and the end of the rotating shaft 16 is sufficient for picking up, putting down, or replacing the laser film roll, the laser film roll can be put into the rotating shaft 16 or the wound-up laser film roll can be removed from the rotating shaft 16.

[0033] Then rotate the actuation wheel 23 in the opposite direction to reset the moving plate 18 until the free end of the rotating shaft 16 is inserted into the circular groove 21 of the moving plate 18. This completes the support and limiting of both ends of the rotating shaft 16, which not only ensures the stability during winding, but also greatly simplifies the handling and replacement of the laser film, and improves the ease of use of the equipment.

[0034] In this invention, the initial extension degree of the telescopic spring 5 can be precisely adjusted through the linkage structure of the first threaded rod 6, the slider 7, the vertical rod 8 and the rectangular frame 24, thereby controlling the downward movement distance of the slide plate 4. When the molding plate presses the laser film, the elastic deformation capability of the telescopic spring 5 under the slide plate 4 changes with the adjustment, so that the surface of the laser film forms a concave-convex structure of different depths. Combined with the principle of light reflection, the concave-convex textures of different depths can produce a variety of diffuse reflection effects, which solves the problem of the same concave-convex depth and single presentation effect in traditional devices, and meets diverse visual needs.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0036] 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.
