Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a bag sealing and labeling machine. Background Technology

[0002] In the modern packaging industry, the application of automated equipment has become a key factor in improving production efficiency, reducing labor costs, and ensuring product quality. As a multi-functional automated device integrating sealing, labeling, and shaping, bag sealing and labeling machines are widely used in food, pharmaceuticals, chemicals, daily necessities, and other fields. Traditional packaging processes typically rely on manual operation, which is not only inefficient but also prone to product quality instability due to human error. With the continuous development of industrial automation, the emergence of bag sealing and labeling machines has effectively solved these problems, realizing fully automated operation from material conveying, sealing, labeling to shaping and output.

[0003] In existing technologies, various labeling devices are applied to different scenarios. For example, some labeling machines use conveyor belts to transport products to designated locations, and then use vacuum adsorption devices to peel the labels off the backing paper and attach them to the product surface. However, these devices still have many shortcomings in practical applications. For instance, when labeling bagged products, the bags need to be sealed simultaneously with the labels. Because bags themselves have a certain degree of softness and deformability, without an effective positioning and support structure, the labels can easily become uneven or misaligned, thus affecting the packaging quality of the product. Utility Model Content

[0004] This invention aims to at least solve the technical problems existing in the prior art. To this end, this invention proposes a bag sealing and labeling machine that can shape and fold the edges of bags, and then attach the label tightly to the folded surface after shaping and folding.

A connecting plate is provided on the top of one side of the conveying mechanism. The labeling mechanism includes a lifting drive mechanism and an adsorption mechanism. The adsorption mechanism is located at the output end of the lifting drive mechanism. The label peeling mechanism and the lifting drive mechanism are both located on the connecting plate. The bag folding mechanism includes a bending drive mechanism, a bending plate, and a shaping plate. The bending drive mechanism and the shaping plate are located on both sides of the conveying mechanism. The output end of the bending drive mechanism is connected to the bending plate.

By setting up a bending drive mechanism, a bending plate, and a shaping plate in conjunction, the bag is folded and shaped before labeling, making the surface smoother and improving the product appearance quality and label adhesion. By opening a first labeling window at the top of the shaping plate, and placing the window directly below the bottom of the adsorption mechanism, the shaping plate can avoid being misaligned during the labeling process, without affecting the labeling steps.

[0024] like Figures 1-3 As shown in the figure, this utility model embodiment provides a bag sealing and labeling machine.

[0025] A bag sealing and labeling machine includes a conveying mechanism 1, a peeling mechanism 2, a labeling mechanism 3, and a bag folding mechanism 4. A connecting plate 5 is provided on the top of one side of the conveying mechanism 1. The labeling mechanism 3 includes a lifting drive mechanism 6 and an adsorption mechanism 7. The adsorption mechanism 7 is located at the output end of the lifting drive mechanism 6. The peeling mechanism 2 and the lifting drive mechanism 6 are both located on the connecting plate 5. The bag folding mechanism 4 includes a bending drive mechanism 8, a bending plate 9, and a shaping plate 10. The bending drive mechanism 8 and the shaping plate 10 are located on both sides of the conveying mechanism 1. The output end of the bending drive mechanism 8 is connected to the bending plate 9. A first labeling window 12 is opened on the top of the shaping plate 10. The first labeling window 12 is located at the bottom of the adsorption mechanism 7.

[0026] This utility model integrates conveying, label peeling, labeling, bag folding, and shaping functions into a single bag-sealing and labeling machine. By employing a lifting drive mechanism 6 in conjunction with an adsorption mechanism 7, precise adsorption and positioning of labels can be achieved, minimizing deviation during the labeling process and ensuring labeling quality. The bending drive mechanism 8, bending plate 9, and shaping plate 10 work together to fold and shape the bag before labeling, resulting in a smoother surface and improved product appearance and label adhesion. A first labeling window 12 is provided at the top of the shaping plate 10, located directly below the bottom of the adsorption mechanism 7, allowing the shaping plate 10 to avoid obstructing the labeling process.

[0027] This embodiment of a bag sealing and labeling machine includes a label peeling mechanism 2 comprising a rotary drive mechanism 13, a feeding roller 14, a receiving roller 15, and a peeling block 16. Both the feeding roller 14 and the receiving roller 15 are rotatably mounted on the connecting plate 5. Both the rotary drive mechanism 13 and the peeling block 16 are also mounted on the connecting plate 5. The output end of the rotary drive mechanism 13 is connected to the receiving roller 15 via a transmission connection. The label roll sequentially passes through the feeding roller 14, the peeling block 16, and the receiving roller 15. Specifically, the label peeling mechanism 2 drives the receiving roller 15 to rotate via the rotary drive mechanism 13, causing the label roll to move from the feeding roller 14 to the receiving roller 15, and then passes through the peeling block 16 to complete the label peeling operation. This enables continuous automatic label peeling, improving work efficiency while reducing manual intervention and ensuring a stable and reliable peeling process.

[0028] The label sealing and labeling machine described in this embodiment includes a label peeling mechanism 2 comprising two or more guide rollers 17, all of which are rotatably mounted on the connecting plate 5. The guide rollers 17 are positioned between the feeding roller 14 and the peeling block 16, and between the receiving roller 15 and the peeling block 16. Specifically, adding guide rollers 17 effectively controls the running path of the label tape, ensuring it passes smoothly over the peeling block 16, avoiding deviation or jamming, thereby improving the stability and consistency of label peeling, extending the equipment's service life, and reducing the failure rate.

[0029] This embodiment of a bag sealing and labeling machine includes a first slide rail 18 on a connecting plate 5, a positioning plate 19 on the outer side of the peeling block 16, and a first slider 20 on the outer side of the positioning plate 19. The first slider 20 is slidably connected to the first slide rail 18. A push rod cylinder 21 is provided on the connecting plate 5, and the output end of the push rod cylinder 21 is connected to the positioning plate 19. Specifically, this structure enables the position adjustment function of the peeling block 16. By pushing the positioning plate 19 along the slide rail 18 with the push rod cylinder 21, the position of the peeling block 16 can be finely adjusted to adapt to label materials of different sizes or thicknesses, enhancing the applicability and flexibility of the equipment and ensuring the precise execution of the peeling action.

[0030] This embodiment of a bag sealing and labeling machine includes a plurality of sleeve adjustment assemblies 22 disposed on the top side of one side of the conveying mechanism 1, with the bottom of the connecting plate 5 disposed on top of the sleeve adjustment assemblies 22. Specifically, the sleeve adjustment assemblies 22 allow adjustment of the position of the connecting plate 5 according to the height of the packaging bag, thereby optimizing the labeling height and ensuring accurate labeling position. This design enhances the adaptability of the equipment and is suitable for labeling various sizes of packaging bags.

[0031] In this embodiment of the bag sealing and labeling machine, a lifting plate 23 is detachably mounted on the top of the other side of the conveying mechanism 1, and the bending drive mechanism 8 is mounted on top of the lifting plate 23. Specifically, the detachable lifting plate 23 facilitates maintenance and replacement, and the height of the bending drive mechanism 8 can be adjusted as needed to make the bending plate 9 more accurately match the packaging bag, thereby improving bag folding efficiency and the overall flatness after labeling.

[0032] The bag sealing and labeling machine described in this embodiment has a second labeling window 24 on the bending plate 9. Specifically, the first labeling window 12 and the second labeling window 24 are correspondingly arranged. The second labeling window 24 is provided on the bending plate 9 so that the bending plate 9 can be kept within the shaping plate 10 after the bag is folded, and labeling operations can still be performed during this process, avoiding the impact of bag folding on labeling accuracy. This design improves the coordination between the labeling and bag folding processes, ensures that the labeling position is not affected by bag folding, and improves the product appearance quality.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
