Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a cold foil film conveying device. Background Art

[0002] Cold foil is a film material widely used in the printing and packaging industries to protect and enhance images, printed materials, or other surfaces. During the production process, the film is applied to the material surface via a conveyor. A cold foil conveyor is a mechanical device used to evenly apply the film to the surface of printed materials or other materials. This device typically combines a conveyor system, a cold foil reel, and a pressure-applying mechanism to ensure a good bond between the film and the substrate.

[0003] Existing cold foil conveyor systems use a conveyor belt to transport the material to be processed to the cold foil application area. A cold foil reel is used to store the cold foil, and a pressure device, such as a roller or other mechanical structure, applies appropriate pressure between the film and the surface to be processed to ensure good adhesion between the film and the substrate. However, over time and with continuous use, the guide rollers will wear out, causing the surface to become rough or uneven, thus affecting their performance. Currently, the guide rollers are fixed to the machine with screws at both ends, requiring specialized tools to remove them each time. Therefore, a cold foil conveyor device has been proposed to address this issue. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment of a cold stamping film conveying device, comprising a support plate 1, a bracket 2 is fixedly connected to the lower surface of the support plate 1, a winding drum 3 is fixedly connected to the side wall of the support plate 1, and the winding drum 3 is used to store the cold stamping film, the side wall of the support plate 1 is fixedly connected to a fixing frame 4, a pressure roller 5 is arranged inside the fixing frame 4, and the pressure roller 5 is used to apply appropriate pressure between the film and the surface to be processed, a sleeve 6 is rotatably connected to the inside of the fixing frame 4, a transverse groove 7 is opened inside the sleeve 6, a pull rod 8 is slidably connected to the inside of the sleeve 6, a slider 9 is fixedly connected to the side wall of the pull rod 8, and a spring 10 is provided on the side wall of the pull rod 8, and the spring 10 is used for rebounding and resetting. One end of the spring 10 is fixedly connected to Connected to the inside of the sleeve 6, the other end of the spring 10 is fixedly connected to the side wall of the slider 9, and the side wall of the slider 9 is fixedly connected with a clamping column 11, and the clamping column 11 is used for fixing. The inside of the pressure roller 5 is fixedly connected to the fixing rod 12, and the clamping column 11 is slidably connected to the inside of the fixing rod 12. A rotating assembly is provided on the side wall of the fixing frame 4. The rotating assembly is used to drive the pressure roller 5 to rotate. The rotating assembly includes a first gear 13, a second gear 14 and a first motor 15. The first gear 13 is fixedly connected to the side wall of the sleeve 6, and the side wall of the second gear 14 is rotatably connected to the side wall of the fixing frame 4. The first gear 13 is meshed with the second gear 14, and the output end of the first motor 15 is connected to the second gear 14;

[0032] As time goes by and with continuous use, the pressure roller 5 will suffer from wear and need to be replaced. First, by pulling the pull rod 8, the slider 9 is made to slide inside the transverse groove 7. The movement of the slider 9 squeezes the spring 10 to make it shrink, and the slider 9 drives the clamping column 11 to move, so that it is disengaged from the inside of the fixed rod 12, canceling the fixed relationship with the fixed rod 12, and then removing it, making it convenient to replace the pressure roller 5. When installing a new pressure roller 5, the slider 9 is moved by pulling the pull rod 8 again. The slider 9 drives the clamping column 11 to move so that the clamping column 11 enters the inside of the sleeve 6, and then aligns the fixed rod 12 with the clamping column 11. After releasing the pull rod 8, the spring 10 loses the squeezing of the slider 9 and rebounds to reset, and the clamping column 11 is clamped into the inside of the fixed rod 12 again to fix it, completing the installation of the pressure roller 5. Then, the first motor 15 is started to drive the second gear 14 to rotate. The second gear 14 is in meshing relationship with the first gear 13, thereby driving the first gear 13 to rotate. The first gear 13 drives the sleeve 6 to rotate. The rotation of the sleeve 6 drives the clamping column 11 to rotate through the slider 9. The clamping column 11 drives the fixed rod 12 to rotate through its fixed relationship with the fixed rod 12, thereby causing the pressure roller 5 to rotate and work.

[0033] Reference Figure 1 and Figure 4, the side wall of the support plate 1 is fixedly connected to a guide roller 16, which guides the movement and position of the cold stamping film. A moving roller 17 is provided on the side wall of the support plate 1, and a slide groove 18 is opened inside the support plate 1. A third gear 19 is provided inside the support plate 1, and the third gear 19 is rotatably connected to the inside of the slide groove 18. A slide rail 21 is provided inside the support plate 1, and the slide rail 21 is used for sliding. The side wall of the slide rail 21 is fixedly connected to the inside of the slide groove 18. A rack 20 is slidably connected to the inside of the slide rail 21. The rack 20 is used to drive the slide plate 22 to move. The slide rail 21 is slidably connected to the inside of the slide rail 21. The side wall of the slide plate 22 is fixedly connected to the side wall of the moving roller 17. The third gear 19 meshes with the rack 20, and the rack 20 is connected to the slide plate 22. A fixed frame 23 is fixedly connected to the lower surface of the support plate 1. A second motor 24 is provided inside the fixed frame 23, and the output end of the second motor 24 is connected to the third gear 19;

[0034] When faced with film materials of different thicknesses and types, it is necessary to adjust the distance between the guide roller 16 and the moving roller 17 to ensure that the material will not be deformed or torn due to uneven tension. First, the second motor 24 is started to rotate the third gear 19, and the third gear 19 is in a meshing relationship with the rack 20. The rotation of the third gear 19 drives the rack 20 to move, so that the rack 20 slides inside the slide rail 21. At the same time, the rack 20 is connected to the slide 22, thereby driving the slide 22 to move. The movement of the slide 22 drives the fixed moving roller 17 to move, and the position of the moving roller 17 is adjusted to complete the adjustment of the distance between the guide roller 16 and the moving roller 17.

[0035] Working principle: When the pressure roller 5 needs to be replaced, the slider 9 is moved by pulling the pull rod 8. The movement of the slider 9 squeezes the spring 10 to make it contract, thereby driving the post 11 to move, so that it disengages from the inside of the fixed rod 12, canceling the fixation of the fixed rod 12, and facilitating the replacement of the pressure roller 5. When installing the pressure roller 5, the pull rod 8 is pulled again to move the slider 9, driving the post 11 to move, and then after aligning the fixed rod 12 with the post 11, the pull rod 8 is released, the spring 10 loses its extrusion and resets, and the post 11 is stuck in the inside of the fixed rod 12 to fix it, completing the installation of the pressure roller 5. Then, the first motor 15 is started to drive the second gear 14 to rotate, and the second gear 14 is meshed with the first gear 13, thereby driving the first gear 13 to rotate, and the first gear 13 drives the sleeve 6 to rotate. The rotation of the sleeve 6 drives the post 11 to rotate through the slider 9, and the rotation of the post 11 drives the fixed rod 12 to rotate, thereby making the pressure roller 5 rotate and work.

[0036] When it is necessary to adjust the distance between the guide roller 16 and the movable roller 17, the third gear 19 is rotated by starting the second motor 24. The third gear 19 is in meshing relationship with the rack 20, thereby driving the rack 20 to move, so that it slides inside the slide rail 21, and at the same time drives the slide plate 22 to move. The movement of the slide plate 22 drives the movable roller 17 to move, so that the distance between the guide roller 16 and the movable roller 17 is adjusted.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
