Description
Technical Field
[0001] This utility model relates to the field of labeling technology, and in particular to a three-sided labeling device for a labeling machine. Background Technology
[0002] A labeling machine is a device that uses adhesive to affix paper or metal foil labels to designated packaging containers. Labeling machines are an indispensable part of modern packaging. Currently, the types of labeling machines produced in my country are gradually increasing, and the technical level has also greatly improved. The industry has shifted from the backward situation of manual and semi-automatic labeling to a situation where automated high-speed labeling machines occupy a large market share.
[0003] As label content increases, labeling only one side of packaging containers can no longer meet the demand. Therefore, long labels have appeared on the market. When labeling, the middle of the label is first pasted to one side of the packaging container, and then the labeling machine pastes the two ends of the label to the other two sides of the packaging container at the same time, so as to achieve labeling on three sides of the packaging container.
[0004] However, commercially available three-sided labeling devices typically involve first affixing the center of the label to the front of the packaging container, then using a conveyor belt to transport the container. During transport, the container passes through brushes on both sides of the conveyor belt, which then adhere the two ends of the label to the other two sides of the container. This type of three-sided labeling method cannot ensure the strong adhesion between the label ends and the packaging container. Furthermore, because the brushes are fixed, they can only label packaging containers of a single size, resulting in poor practicality for this type of three-sided labeling device. Utility Model Content
[0005] The purpose of this invention is to provide a three-sided labeling device for a labeling machine that ensures strong adhesion, allows for multi-directional adjustment, and improves practicality and versatility.
[0006] To solve the above technical problems, the present invention can be implemented using the following technical solutions:
[0007] A three-sided labeling device for a labeling machine includes a base, a mounting plate, a drive unit, and labeling units. An adjusting groove is provided on the base. The lower part of the mounting plate is movably connected to the base via the adjusting groove. A vertical adjustment hole is provided on the upper part of the mounting plate. The drive unit is movably connected to the mounting plate via the vertical adjustment hole, and a fixed plate is connected to the output end of the drive unit. Horizontal adjustment holes are provided on both sides of the fixed plate. Two sets of labeling units are provided, and the two sets of labeling units are movably positioned on both sides of the fixed plate via the horizontal adjustment holes, thereby adjusting the spacing between the two sets of labeling units.
[0008] In one embodiment, the labeling unit includes a fixed frame, a movable arm, and a labeling roller. The fixed frame is movably connected to a fixed plate through a lateral adjustment hole. One end of the movable arm is connected to the fixed frame, and the labeling roller is rotatably disposed at the other end of the movable arm.
[0009] In one embodiment, the movable arm and the fixed frame are rotatably connected.
[0010] In one embodiment, the movable arm has a connecting rod, and a movable pull column is provided on the inner side wall of the connecting rod, and a fixed pull column is provided on the inner side wall of the fixed frame, and an elastic element connects the movable pull column and the fixed pull column.
[0011] In one embodiment, the lower part of the mounting plate is provided with a first limiting groove that mates with the base.
[0012] In one embodiment, the fixing frame is provided with a second limiting groove that cooperates with the fixing plate.
[0013] In one embodiment, the fixing plate has several weight-reducing holes.
[0014] In one embodiment, the elastic element is a tension spring.
[0015] In one embodiment, the driving element is a cylinder.
[0016] In one embodiment, the labeling roller is made of sponge material. Beneficial effects
[0017] This utility model relates to a three-sided labeling device for a labeling machine. The device can be installed on one side of the labeling machine's conveyor line via a base. A drive unit propels the labeling units on both sides of a fixed plate, allowing two sets of labeling units to simultaneously adhere both ends of the label to the sides of the packaging container. This ensures a tight and secure bond between the label ends and the packaging container. Furthermore, the front-to-back position and height of the labeling units can be adjusted via adjusting the slide groove and vertical adjustment hole, while the spacing between the two sets of labeling units can be adjusted via the horizontal adjustment hole. This allows for multi-directional adjustment of the labeling units, enabling the two sets of labeling units to label three sides of packaging containers of different sizes, thereby improving the practicality and versatility of the three-sided labeling device.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0033] Please see Figure 1 and Figure 5 A three-sided labeling device for a labeling machine includes a base 100, a mounting plate 200, a drive unit 300, and labeling units 400. An adjustment groove 110 is provided on the base 100. The lower part of the mounting plate 200 is movably connected to the base 100 via the adjustment groove 110. A vertical adjustment hole 210 is provided on the upper part of the mounting plate 200. The drive unit 300 is movably connected to the mounting plate 200 via the vertical adjustment hole 210, and a fixing plate 500 is connected to the output end of the drive unit 300. Horizontal adjustment holes 510 are provided on both sides of the fixing plate 500. Two sets of labeling units 400 are provided, and the two sets of labeling units 400 are movably mounted on both sides of the fixing plate 500 via the horizontal adjustment holes 510, thereby adjusting the spacing between the two sets of labeling units 400.
[0034] Specifically, in this embodiment, the three-sided labeling device can be installed on the side of the labeling machine's conveyor line via the base 100. After the middle of the label is pasted onto the packaging container, the packaging container is conveyed by the conveyor line. When it is conveyed to the three-sided labeling device, the driving component 300 will drive the fixing plate 500 to move towards the conveyor line. The driving component 300 is a cylinder. When the fixing plate 500 moves, it will move the labeling units 400 on both sides. The two sets of labeling units 400 will act on both ends of the label at the same time, pressing the two ends of the label tightly against both sides of the packaging container to achieve three-sided labeling. Moreover, the two sets of labeling units 400 can ensure that the two ends of the label are firmly and tightly pasted to the packaging container after being pasted, and there will be no situation where the label is not tightly pasted.
[0035] Meanwhile, the position of the mounting plate 200 can be adjusted by adjusting the slide groove 110, thereby adjusting the position between the labeling unit 400 and the packaging container on the conveyor line. The vertical adjustment hole 210 can be used to adjust the longitudinal height of the drive component 300, thereby adjusting the height position of the labeling unit 400. The horizontal adjustment hole 510 can be used to adjust the spacing between the two sets of labeling units 400, so that the two sets of labeling units 400 can better cooperate with the packaging container. Ultimately, the labeling unit 400 can be adjusted in multiple directions to match different models, specifications and sizes of packaging containers, improving the versatility and practicality of the three-sided labeling device.
[0036] Please see Figure 6 To achieve labeling at both ends, the labeling unit 400 in this embodiment includes a fixed frame 410, a movable arm 420, and a labeling roller 430. The fixed frame 410 is movably connected to the fixed plate 500 through a lateral adjustment hole 510. One end of the movable arm 420 is connected to the fixed frame 410, and the labeling roller 430 is rotatably disposed at the other end of the movable arm 420. During labeling, the driving component 300 drives the fixed plate 500 to move towards the packaging container on the conveyor line. When the fixed plate 500 moves, it moves the fixed frame 410, thereby moving the movable arm 420. The movable arm 420, in turn, drives the labeling roller 430 to move, causing the labeling roller 430 to act on the label. The labeling roller 430 rolls while pressing both ends of the label onto the two sides of the packaging container, thus achieving labeling at both ends.
[0037] To ensure a tight and secure adhesion of the label ends after it is affixed to the packaging container, the movable arm 420 and the fixed frame 410 in this embodiment are rotatably connected. The movable arm 420 has a connecting rod 440, and a movable pull post 441 is provided on the inner side wall of the connecting rod 440. A fixed pull post 411 is provided on the inner side wall of the fixed frame 410. An elastic element (not shown in the figure) connects the movable pull post 441 and the fixed pull post 411. When the label rollers 430 on both sides press and affix the label ends, the reaction force from the packaging container drives the label rollers 430 to open outward. At the same time, the tension of the elastic element between the movable pull post 441 and the fixed pull post 411 causes the label rollers 430 to apply pressure to both ends of the label simultaneously, thereby pressing the two ends of the label tightly against the two sides of the packaging container. This ensures that the two ends of the label are tightly and securely affixed to the packaging container. The elastic element is a tension spring.
[0038] In addition, to prevent the labeling roller 430 from scratching the label during labeling, the labeling roller 430 in this embodiment is made of sponge material. Because sponge material is soft and has good resilience, it can protect the label well and prevent it from being scratched, thereby ensuring the labeling quality.
[0039] Please see Figure 4 Figure 5To facilitate the movable assembly between the mounting plate 200 and the base 100, and between the labeling unit 400 and the fixing plate 500, a first limiting groove 220 that mates with the base 100 is provided at the lower part of the mounting plate 200, and a second limiting groove 412 that mates with the fixing plate 500 is provided on the fixing frame 410. By matching the vertical width of the first limiting groove 220 with that of the base 100, the mounting plate 200 and the base 100 can be limited, thus facilitating the movable connection between the mounting plate 200 and the base 100 via the adjusting slide 110. Similarly, by matching the vertical width of the second limiting groove 412 with that of the fixing plate 500, the fixing frame 410 and the fixing plate 500 can be limited, thereby facilitating the movable connection between the labeling unit 400 and the fixing plate 500 via the transverse adjusting hole 510, ultimately facilitating the assembly of the three-sided labeling device.
[0040] Finally, please see Figure 5 Since the three-sided labeling device has a certain weight, in order to ensure that the three-sided labeling device can be stably installed on the side of the labeling machine conveyor line, in this embodiment, a number of weight-reducing holes 520 are provided on the fixing plate 500. The weight-reducing holes 520 can effectively reduce the weight of the fixing plate 500 and ensure the strength of the fixing plate 500, thereby reducing the overall weight of the three-sided labeling device and making the three-sided labeling device more stable after being fixed on the side of the conveyor line.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
