Description

Technical Field

[0001] This utility model relates to the field of label application technology, specifically a label application positioning device. Background Technology

[0002] Label films can protect the label surface from physical wear and scratches, extending the label's lifespan. The film material is usually waterproof, preventing moisture from penetrating the label, especially in humid or high-humidity environments.

[0003] The high-performance BOPP thermal film label positioning device, as described in announcement number CN220885125U, includes a processing table. A support leg is fixedly connected to the bottom of the processing table, and a placement platform is fixedly connected to the top of the processing table. A limiting plate is fixedly connected to the front of the placement platform. An adjustment hole is provided inside the processing table, and a movable rod is movably connected inside the adjustment hole. A limiting block is fixedly connected to the top of the movable rod, and a spring is fixedly connected to the bottom of the limiting block. A fixing block is fixedly connected to the bottom of the movable rod. A support column is fixedly connected to the top of the processing table, and a top plate is fixedly connected to the top of the support column. This high-performance BOPP thermal film label positioning device provides excellent positioning performance, facilitates label positioning, prevents label displacement, and effectively improves the accuracy of label application, thus enhancing the device's practicality.

[0004] While the aforementioned film positioning device solves some problems, it still has the following drawbacks:

[0005] The film-applying positioning device applies film to labels placed on the placement table using limiting blocks and limiting plates. A hydraulic push rod drives the limiting cover to cover the label with film. However, when applying film, it is difficult to complete the bonding after simply squeezing the protective film onto the label. Furthermore, if the air between the protective film and the label is not expelled in time, it will affect the quality of the label. Utility Model Content

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0034] like Figures 1 to 5 As shown, this embodiment proposes a label film positioning device, including a film holder 1, a drive assembly 2, a guide mechanism 3, a reset mechanism 4, an electric push rod 5, a support plate 6, a slider 8, a pressing cam 9, a baffle 10, and a pressure plate 11 fixedly connected to the lower end of the electric push rod 5.

[0035] The film applicator 1 consists of a base plate with support columns fixedly connected to the four corners at the top of the base plate. A top plate is then installed above the support columns. A support plate 6 is installed on the lower inner side of the film applicator 1. A placement slot 7 for placing labels is opened on the upper side of the support plate 6. The label to be applied is placed inside the placement slot 7 and the film is covered. Then, the electric push rod 5, which is fixedly connected to the upper inner side of the film applicator 1, extends. The pressure plate 11, which is fixedly connected to the lower end of the electric push rod 5, squeezes the film into the placement slot 7 and cuts off the excess protective film.

[0036] Baffles 10 are provided on both sides inside the film applicator 1. A lead screw 201 is provided on the rear side between the baffles 10. The two ends of the lead screw 201 are rotatably connected to the side of the baffles 10 that are close to each other. A slider 8 is provided inside the film applicator 1. The slider 8 is inside the film applicator 1 and is threadedly connected to the lead screw 201. The lead screw 201 is driven by a servo motor 202 fixedly connected to the outside of the baffles 10. The rotation of the lead screw 201 controls the slider 8 to move to both sides inside the film applicator 1.

[0037] To ensure that the slider 8 can only move to both sides under the rotation of the lead screw 201, a guide rod 301 is provided on the front side between the baffles 10. The two ends of the guide rod 301 are fixedly connected to the side of the baffles 10 that are close to each other. The guide rod 301 is fitted with a guide hole 302 opened at the front position on one side of the slider 8, ensuring that the slider 8 can only move to both sides along the axial direction of the guide rod 301 through the guide hole 302. A pressing cam 9 is provided on the lower side inside the slider 8. The two ends of the pressing cam 9 are rotatably connected to the front and rear sides inside the slider 8, and the rotating shafts at both ends of the pressing cam 9 extend from the inside of the slider 8 to the front and rear sides outside the slider 8. Example

[0038] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0039] A toothed rod 204 is provided at both the front and rear inside the film applicator 1. The two ends of the toothed rod 204 are fixedly connected to the front and rear sides inside the film applicator 1, respectively. The teeth of the toothed rod 204 face downwards. A gear 203 that meshes with the lower teeth of the toothed rod 204 is fixedly connected to the rotating shafts at the front and rear of the extrusion cam 9. As the slider 8 moves to both sides, it drives the gear 203 to move as well. The movement of the gear 203 is driven by the toothed rod 204. The gear 203 will drive the extrusion cam 9 to rotate. The direction of rotation of the lower side of the extrusion cam 9 is the same as the direction of movement of the slider 8. The film covering the label is extruded and adhered, so that the film covering the label can be more tightly adhered to the label. A foot support 12 is fixedly connected to the front, rear and sides of the lower end of the film applicator 1 to support the film applicator 1. Example

[0040] The following section provides a further description of the scheme in Example 2, focusing on its specific working method. See the description below for details:

[0041] To generate pressure between the extrusion cam 9 and the support plate 6 to compress the film attached to the label, support rods 401 are fixedly connected to the front, back, and sides of the lower side of the support plate 6. The lower ends of the support rods 401 extend out through the interior of four movable slots 402 opened on the lower side of the film applicator 1. A stop block 403 is provided at the lower end of each support rod 401. The stop block 403 is threadedly connected to the lower end of the support rod 401, which facilitates the replacement of the support plate 6 with different sizes of placement slots 7. A buffer spring 404 is sleeved on the outside of each support rod 401. The buffer spring 404 is between the lower side of the support plate 6 and the interior of the film applicator 1, and presses the support plate 6 upward, so that when the extrusion cam 9 passes over the upper side of the support plate 6, it can generate pressure between the extrusion cam 9 and the interior of the placement slot 7. Furthermore, both sides of the support plate 6 are curved arc surfaces, which facilitates the movement of the extrusion cam 9 to the upper side of the support plate 6.

[0042] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
