Description

Technical Field

[0001] This utility model relates to the field of beverage bottle labeling technology, specifically a labeling device. Background Technology

[0002] Beverage bottles are liquid packaging containers. To display the beverage brand, labels are applied to their surfaces using labeling machines. Labeling machines play a crucial role in the modern packaging industry, significantly improving the level of automation in the production process by accurately and efficiently affixing labels to products.

[0003] Currently, some existing labeling machines lack an effective real-time limiting mechanism, which may cause beverage bottles to shift during the labeling process, affecting labeling accuracy. Even if some labeling machines for beverage bottles are designed with limiting structures, the labeling structure and limiting structure of existing labeling machines are often controlled independently. The labeling and limiting actions are often controlled by different drive sources, resulting in asynchronous actions, response delays, and difficulty in achieving precise coordination. Therefore, a labeling device is proposed. Utility Model Content

A slide rail is fixed on the adjusting seat. The linkage seat is slidably connected to the outside of the corresponding slide rail.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the limiting block has a U-shaped cross-section and an opening, with an flared angle at the opening so that the limiting block can cut into the outside of the beverage bottle.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-3 As shown, a labeling device in this embodiment is mainly used to label beverage bottles 8. It includes a base 1, on which a conveyor 2 is provided for conveying the beverage bottles 8. An adjusting seat 3 is also fixedly provided on the base 1, and a linkage structure 4 is provided on the adjusting seat 3. Limiting blocks 5 and labeling structures 6 are provided opposite to each other on both sides of the conveyor 2. The labeling structure 6 is used to complete the labeling of the beverage bottles 8, while the limiting blocks 5 are used to limit the beverage bottles 8 when they are being labeled. As for the linkage structure 4, it moves the limiting blocks 5 closer to or further away from the beverage bottles 8 when the labeling structure 6 is working, so as to ensure that the labeling work is carried out smoothly.

[0019] It should also be noted that a support 7 is fixedly installed on the conveyor 2, and photoelectric sensors are installed on the two inner side walls opposite to each other on the support 7 to detect the beverage bottle 8, so that the labeling structure 6 can complete the labeling work. The design of the photoelectric sensor is a mature existing technology for the labeling device used to label the beverage bottle 8, and will not be elaborated on here.

[0020] First, the conveyor 2 is described. The conveyor 2 includes a conveyor frame. Support legs are fixedly installed between the conveyor frame and the box base 1, so that the conveyor frame is set above the box base 1, thereby providing space support for the adjustment seat 3 and the linkage structure 4. A conveyor belt is installed on the inner side of the conveyor frame, and multiple conveyor rollers are installed on the inner side of the conveyor belt. A drive motor with a reducer is installed on the outer side of the conveyor frame to make the conveyor belt work and realize the conveying of the beverage bottle 8. In addition, a side baffle is installed on the conveyor frame to prevent the beverage bottle 8 from falling.

[0021] The labeling structure 6 includes two sets of rollers 61 rotatably mounted on the adjusting seat 3. Labeling tape is wound between the two rollers 61. One set is used for winding, and the other set is used for supplying the labeling tape. (Example) Figure 1 Taking the viewpoint as an example, the right-side roller 61 is used for winding. At this time, it should be noted that there is space inside the adjusting seat 3, and a drive source is fixedly installed by bolts. The output end of the drive source is connected to the right-side roller 61. The drive source is, for example, a motor equipped with a reducer, which is not shown in the figure.

[0022] Further explanation of the labeling structure 6: The labeling structure 6 also includes an extension plate fixed to the outside of the conveyor frame of the conveyor 2. A positioning block 62 is fixed on the extension plate. When the labeling tape is conveyed, one side is attached to the outside of the positioning block 62. A labeling opening 63 is provided on the outside of the positioning block 62. A mounting plate 64 is also fixed on the extension plate. A telescopic member 65 is bolted to the outside of the mounting plate 64. The telescopic member 65 is either a cylinder or an electric push rod. A frame knife 66 is assembled at the telescopic end of the telescopic member 65. The frame knife 66 can extend and retract through the telescopic action of the telescopic member 65 to pass through the labeling opening 63, so that the labeling tape is cut into labels and attached to the bottle body of the beverage bottle. This is the prior art in the publication number CN223174522U, "An Automatic Labeling Machine for Beverage Bottles".

[0023] As a key aspect of this application, to ensure that the limiting block 5 can temporarily limit the beverage bottle 8 when the telescopic component 65 has completed its extension and retraction for labeling, in this embodiment, the limiting block 5 has a U-shaped cross-section with an opening when viewed from above. The opening has an flared angle to allow the limiting block 5 to cut into the outside of the beverage bottle 8. The linkage structure 4 includes two sets of connecting plates 41, which are respectively fixedly connected to the limiting block 5 and the frame base knife 66. Connecting posts 4 are fixed at the bottom of the two sets of connecting plates 41. 2. A linkage seat 43 is fixed at the bottom of the connecting column 42. A central shaft 44 is fixed on the adjusting seat 3. A rotating rod 45 is rotatably connected to the outside of the central shaft 44. The two sides of the upper surface of the rotating rod 45 are respectively hinged to the lower surface of the adjacent linkage seat 43. The hinge point between the linkage seat 43 and the connecting rod 46 is located in the middle of the lower surface of the linkage seat 43. In addition, a slide rail 47 is fixed on the adjusting seat 3. There are four sets of slide rails 47. The linkage seat 43 is slidably connected between the outer sides of the corresponding two sets of slide rails 47.

[0024] It should be noted that the expansion plate has a waist-shaped hole to provide the corresponding connecting post 42 with the required movement space. The length of the waist-shaped hole is used to control the stroke of the corresponding connecting post 42, and its length does not exceed the extension stroke range of the telescopic component 65. Figure 3 From a visual perspective, the connecting post 42 on the left side is slidably connected to the inside of the waist hole.

[0025] With this design, when the frame base knife 66 moves, the limiting blocks 5 can move towards each other. In this way, when the telescopic part 65 has finished telescopically extending and labeling, the limiting blocks 5 can temporarily limit the beverage bottle body 8, ensuring that the labeling is completed smoothly.

[0026] The operating instructions for this labeling device are as follows: When conveyor 2 starts, beverage bottle 8 is conveyed forward by the conveyor belt. After the photoelectric sensor on the bracket 7 detects that the bottle is in place, it sends a signal to trigger the labeling structure 6 to work. The linkage structure 4 then links the limit block 5 to temporarily limit the beverage bottle 8. After the labeling is completed, the telescopic part 65 retracts, the linkage structure 4 drives the limit block 5 to reset, and the conveyor 2 continues to convey the next bottle.

[0027] The labeling structure 6 works as follows: the labeling tape is wound between two rollers 61. The labeling tape passes outside the positioning block 62. The telescopic component 65 pushes the frame seat knife 66 through the labeling opening 63 to cut and press the labeling tape onto the outside of the beverage bottle body 8.

[0028] Working principle of linkage structure 4: When the frame seat knife 66 moves, the motion is transmitted through the connecting plate 41, connecting column 42 and linkage seat 43. The rotating rod 45 rotates around the central axis 44, and the linkage seat 43 on the other side slides along the slide rail 47 through the connecting rod 46, thereby realizing the synchronous movement of the limit block 5 and the frame seat knife 66 towards or away from each other.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
