Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting laser film winding technology, and in particular to an effective anti-counterfeiting laser film slitting and winding device. Background Technology

[0002] The slitting mechanism can cut wide anti-counterfeiting laser film to a predetermined width. For example, in the packaging industry, product labels may require laser film of different widths. By precisely adjusting the spacing of the slitting blades, the laser film can be cut into narrow strips ranging from a few millimeters to tens of centimeters in width to accommodate various label sizes.

[0003] For example, in the prior art, patent CN217577557U discloses an effective slitting and winding device for anti-counterfeiting laser film, including a winding motor, a winding shaft, and a core seat. The winding motor drives the winding shaft, and the core seats are mounted on the winding shaft. There are several core seats. The winding shaft is provided with an air inlet, an exhaust outlet, and several core seat air channels. The core seat air channels are connected to the core seats and correspond one-to-one with the core seats. When air enters through the air inlet, the core seat expands, thereby tightening the winding paper tube. When air is exhausted, the core seat contracts, thereby loosening the winding paper tube. This solves the current problems of airbag aging and leakage, slip ring dirt and failure, and inability to tightly clamp the paper tube.

[0004] While the aforementioned patents have addressed some of the problems in the prior art to a certain extent, they still have some shortcomings. Due to the different forces exerted on the anti-counterfeiting laser film by different equipment units, the tension of the anti-counterfeiting laser film is prone to fluctuations. The floating roller can sense this change in tension and adjust itself by floating. However, existing devices cannot adjust the fluctuation range of the floating roller according to the increase in the winding diameter of the anti-counterfeiting laser film. During use, the area that can be sensed when the tension of the anti-counterfeiting laser film fluctuates may decrease due to the increase in tension. As a result, when the tension is too high, it cannot be detected in time, which may lead to the anti-counterfeiting laser film breaking.

[0005] Therefore, in order to address this problem, this utility model proposes an effective device for slitting and rewinding anti-counterfeiting laser film. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an effective slitting and winding device for anti-counterfeiting laser film that can overcome or at least partially solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The device includes a housing and multiple rewinding and take-up rollers disposed inside the housing. It also includes: a receiving groove, formed inside the housing, with a gear rotatably connected inside the receiving groove, and racks one and two meshing with the gear slidably connected inside the receiving groove; a pressure roller assembly, disposed on one side of rack two, used to smooth the anti-counterfeiting laser film on the surface of the rewinding roller to prevent wrinkling; and a floating roller assembly, disposed on one side of rack one, used to adjust the tension of the anti-counterfeiting laser film.

[0009] Preferably, the inner wall of the housing is fixedly connected with a plurality of partitions, and the outer walls of the plurality of partitions are fixedly connected with the outer wall of the housing by a fixing plate.

[0010] Preferably, the pressure roller assembly includes multiple guide grooves formed on the outer wall of the housing and the outer wall of the partition, and multiple first sliders are slidably connected to the inner walls of the multiple guide grooves, with corresponding first sliders rotatably connected to the pressure rollers.

[0011] Preferably, a first spring is fixedly connected between the inner wall of the guide groove and the outer wall of the first slider, and the first slider is fixedly connected to the rack.

[0012] Preferably, the floating roller assembly includes multiple grooves formed on the outer wall of the housing and the outer wall of the partition, with second sliders slidably connected to the inner walls of the multiple grooves, and floating rollers rotatably connected between corresponding second sliders.

[0013] Preferably, a limiting strip is slidably connected to the inner wall of the groove, a second spring is fixedly connected between the outer wall of the limiting strip and the outer wall of the second slider, and the limiting strip is fixedly connected to the rack.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] This effective slitting and winding device for anti-counterfeiting laser film uses the rotation of the rewinding roller to wind the anti-counterfeiting laser film. As the winding diameter increases, the anti-counterfeiting laser film pushes the pressing roller to slide downward along the guide groove, thereby causing the first slider to slide downward. This causes the second rack to slide downward, driving the gear meshing with the second rack to rotate, which in turn causes the first rack to slide upward. This, in turn, causes the limiting strip to slide upward along the slide groove, causing the entire floating roller group to slide upward. This changes the sensing range of the floating roller, preventing the anti-counterfeiting laser film from being stretched more due to the increase in winding diameter during rewinding, which could lead to increased tension and breakage of the anti-counterfeiting laser film.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0023] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] Reference Figures 1-5The device includes a housing 1 and multiple rewinding rollers 2 and take-up rollers 3 disposed inside the housing 1. It also includes: a receiving groove 8, which is opened inside the housing 1. A gear 10 is rotatably connected inside the receiving groove 8, and a rack 9 and a rack 11 that mesh with the gear 10 are slidably connected inside the receiving groove 8; a pressure roller group, which is disposed on one side of the rack 11, for smoothing the anti-counterfeiting laser film on the surface of the rewinding roller 2 to prevent wrinkling; and a floating roller group, which is disposed on one side of the rack 9, for adjusting the tension of the anti-counterfeiting laser film.

[0026] In this invention, during rewinding, the anti-counterfeiting laser film is wound up by the rotation of the rewinding roller 2. As the winding diameter increases, the anti-counterfeiting laser film can push the pressing roller 64 to slide downward along the guide groove 61, thereby causing the first slider 63 to slide downward. This causes the rack 11 to slide downward, driving the gear 10 meshing with the rack 11 to rotate, thereby causing the rack 9 to slide upward. This, in turn, causes the limiting strip 72 to slide upward along the slide groove 71, causing the entire floating roller group to slide upward. This changes the sensing range of the floating roller 75, preventing the anti-counterfeiting laser film from being stretched more due to the increase in the winding diameter during rewinding, which could lead to increased tension and breakage of the anti-counterfeiting laser film.

[0027] Reference Figures 1-5 Furthermore, multiple partitions 4 are fixedly connected to the inner wall of the housing 1, and a fixing plate 5 is fixedly connected between the outer wall of the multiple partitions 4 and the outer wall of the housing 1. The pressure roller assembly includes multiple guide grooves 61 opened on the outer wall of the housing 1 and the outer wall of the partitions 4. Multiple first sliders 63 are slidably connected to the inner wall of the multiple guide grooves 61. A rolling roller 64 is rotatably connected between the corresponding first sliders 63. A first spring 62 is fixedly connected between the inner wall of the guide groove 61 and the outer wall of the first slider 63. The first slider 63 is fixedly connected to the rack 11. The anti-counterfeiting laser film with gradually increasing diameter can push the rolling roller 64 to slide down along the guide groove 61. Then, the elastic force of the first spring 62 makes the rolling roller 64 fit tightly with the anti-counterfeiting laser film on the rewinding roller 2, so that the rolling roller 64 can smooth out the wrinkles, curls and other unevenness of the anti-counterfeiting laser film.

[0028] Reference Figures 1-5Furthermore, the floating roller assembly includes multiple grooves 71 formed on the outer wall of the housing 1 and the outer wall of the partition 4. The inner walls of the multiple grooves 71 are slidably connected to second sliders 74, and floating rollers 75 are rotatably connected between corresponding second sliders 74. The inner walls of the grooves 71 are slidably connected to limit strips 72. The outer walls of the limit strips 72 and the outer walls of the second sliders 74 are fixedly connected to a second spring 73. The limit strips 72 are fixedly connected to a rack 9. The limit strips 72 slide upward along the grooves 71, causing the floating roller assembly to slide upward as a whole, thereby reducing the increased tension of the floating rollers 75 caused by the increase in the winding diameter of the anti-counterfeiting laser film, thus changing the sensing range of the floating rollers 75.

[0029] 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.
