Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat transfer technology, specifically to a labeling mechanism for box lids. Background Technology
[0002] Heat transfer printing is an emerging printing process that consists of two main parts: transfer film and transfer processing. Patterns or colors are pre-printed on the surface of the film, resulting in rich layers, diverse colors, small color differences, and realistic appearance. It is also suitable for mass production.
[0003] The characteristics of heat transfer printing are simple operation, few production steps, high efficiency, no pollution, small footprint, and low investment. Heat transfer printing is widely used in plastics, cosmetic boxes, toys, electrical appliances, building materials, gifts, food packaging, stationery, and more.
[0004] In the existing technology, when using a labeling mechanism to label the lids of cosmetic boxes, operators need to manually place each lid into the labeling mechanism one by one, and then remove the lids after labeling is completed. This is inefficient, and if there is an operational error during the process of picking up and placing the lids, fingers may be squeezed and injured, posing a certain operational risk.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0024] To address the technical problem in existing technologies where operators manually place the box lid under the heating element for heat transfer printing, resulting in low printing efficiency and certain operational risks, this utility model provides a box lid printing mechanism that can transport the box lid to the underside of the heating element via a conveyor belt, thereby improving the safety performance of the printing mechanism.
[0025] Please see Figures 1-5 , Figures 1-5A labeling mechanism for a box lid, as described in one embodiment of this utility model, includes a worktable 1, a labeling module 2, and a conveying module 3. A support plate 11 is fixedly mounted on the worktable 1. The labeling module 2 includes a mounting base 21, a film supply assembly 22, and a heating element 23. The mounting base 21 is connected to the worktable 1. Both the film supply assembly 22 and the heating element 23 are connected to the mounting base 21. The film supply assembly 22 is used to release and rewind the heat transfer film. A portion of the heat transfer film's transmission path is located on the support plate 1. 1. Between the heating element 23 and the workbench 1; the conveying module 3 is connected to the workbench 1. The conveying module 3 includes a conveyor belt 31, and the conveying plane of the conveyor belt 31 is located above the support plate 11. The conveyor belt 31 is provided with a plurality of protrusions 311 at intervals. When the box cover is placed on a protrusion 311, the conveyor belt 31 can rotate to convey the box cover to the underside of the heating element 23. The heating element 23 presses down the heat transfer film to contact the box cover and heats the heat transfer film.
[0026] It should be noted that the film supply assembly 22 is not limited to a specific structure, as long as it can release and rewind the heat transfer film, no other restrictions are imposed here.
[0027] In this specific embodiment, the film supply assembly 22 includes a winding member 221, an unwinding member 222, and at least two idler rollers 223. The winding member 221 and the unwinding member 222 are both connected to the mounting base 21. The two idler rollers 223 are rotatably connected to the mounting base 21, and the two idler rollers 223 are respectively located below the winding member 221 and the unwinding member 222. The unwinding member 222 is used to release the heat transfer film, and the winding member is used to wind up the heat transfer film after it has been transferred. A section of the transmission path between the two idler rollers 223 is located between the support plate 11 and the heating element 23.
[0028] The take-up component 221 includes a mounting post, a take-up reel, and a geared motor. The mounting post is rotatably connected to the mounting base 21. The geared motor is fixed on the mounting base 21 and its output end is connected to one end of the mounting post. The take-up reel is fixed on the mounting post. The unwinding component 222 includes a guide post and an unwinding reel. One end of the guide post is fixedly connected to the mounting base 21. The unwinding reel is rotatably connected to the guide post. The heat transfer film roll is mounted on the unwinding reel.
[0029] In this specific embodiment, the heating element 23 includes a telescopic part 231 and a heating block 232. The telescopic part 231 is fixedly connected to the mounting base 21, and the heating block 232 is fixedly connected to the movable end of the telescopic part 231. Specifically, the telescopic part 231 is an electric push rod. Of course, in other embodiments, the telescopic part 231 can also be a pneumatic cylinder or a hydraulic cylinder.
[0030] In another embodiment, the heating element 23 further includes an elastic part 233 and a mounting plate 234. The mounting plate 234 is connected to the movable end of the telescopic part 231 via a plurality of elastic parts 233, and the heating block 232 is fixedly connected to the mounting plate 234. It should be noted that by providing the elastic part 233 and the mounting plate 234, the heating block 232 can be buffered to avoid excessive pressure between the heating block 232 and the box body, which could cause damage to the box body.
[0031] In this specific embodiment, the conveying module 3 further includes two rotating shafts 32 and a driving member 33. The two rotating shafts 32 are spaced apart and rotatably mounted on the worktable 1. The conveyor belt 31 is connected between the two rotating shafts 32. The driving member 33 is fixed on the worktable 1 and its output end is connected to one end of one of the rotating shafts 32.
[0032] It should be noted that the driving component 33 is a drive motor, which drives the rotating shaft to rotate, thereby driving the conveyor belt 31 to rotate. In addition, in order to facilitate the collection of the printed boxes, a guide trough 12 is provided on one side of the workbench 1, and a collection box 4 is provided below the guide trough 12. When the box is transported to one end of the transmission plane, the box can roll into the collection box 4 via the guide trough 12.
[0033] Based on the above scheme, the bottom of the collection box 4 is provided with multiple moving rollers 41, of which at least one moving roller 41 has a braking function. At the same time, a handle is provided on one side of the collection box 4 to facilitate the operator to push the collection box 4 to move.
[0034] It should be noted that the protrusion 311 is generally square in shape, and the box body A has a cavity and one end is open. When the box body is placed on the protrusion 311, the protrusion 311 abuts against the bottom wall of the cavity, which can prevent the heating block 232 from squeezing and deforming the box body.
[0035] Based on the above solution, in order to ensure that the position of the stamp on each box is consistent, specifically,
[0036] On the conveyor belt 31, a limiting block 312 is provided on each of the two opposite sides of the protrusion 311. A slot is formed between the two limiting blocks 312 and the opposite sides of the protrusion 311. The opposite sides of the box can be respectively inserted into the two slots. It should be noted that the width of the slot is slightly larger than the width of the side of the box.
[0037] Based on the above scheme, the workbench 1 is provided with multiple idlers 223 at intervals. The multiple idlers 223 are used to support the transmission plane of the conveyor belt 31, and the multiple idlers 223 can effectively improve the support strength of the conveyor belt.
[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
