Description

Technical Field

[0001] This utility model relates to the field of packaging bag embossing technology, and in particular to a vacuum packaging bag embossing device. Background Technology

[0002] Vacuum packaging bags are special plastic bags that create a vacuum environment after sealing the product, extending shelf life and maintaining quality. Embossing can enhance aesthetics and brand recognition, improve anti-slip properties and packaging strength, and provide functions such as breathability, easy tearing, and anti-counterfeiting, meeting personalized needs and enhancing product added value and competitiveness.

[0003] During the embossing process of vacuum packaging bags, the high temperature of the hot stamping melts the plastic material on the surface of the packaging bag. Under pressure, this melted plastic inevitably sticks to the surface of the embossing roller. As the embossing roller rotates and is reused, the residual plastic gradually accumulates on the roller surface. When the embossing roller embosses a new packaging bag surface again, the sticky plastic interferes with the normal embossing process, causing quality problems such as blurry, incomplete, or deformed embossed patterns, thus affecting the overall aesthetics of the vacuum packaging bag and the quality of the product.

[0004] Therefore, this utility model proposes a vacuum packaging bag embossing device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4 As shown, the vacuum packaging bag embossing device provided by this utility model includes a base plate 1. Two sets of support frames 2 are fixedly connected to the top front of the base plate 1. A flattening mechanism is provided on the back of the two sets of support frames 2. The bottom end of the flattening mechanism is fixedly connected to the base plate 1. A cleaning mechanism is provided on the back of the flattening mechanism. The bottom end of the cleaning mechanism is movably sleeved with the base plate 1. The side of the cleaning mechanism is in contact with the embossing roller 6. The inside of the embossing roller 6 is fixedly sleeved with a transmission shaft 7. The two ends of the outer wall of the transmission shaft 7 are movably sleeved with two sets of support plates 4. The bottom end of the support plates 4 is fixedly connected to the base plate 1. The output end of a motor 5 is fixedly connected to the side of the transmission shaft 7. The outer wall of the motor 5 is fixedly connected to the support plates 4.

[0024] The cleaning mechanism includes two sets of scrapers 21, which are arranged vertically. The protruding ends of the two sets of scrapers 21 are evenly attached to the surface of the drive shaft 7. The front of each set of scrapers 21 is fixedly connected to a slag collection trough 20. The outer walls of both sides of the slag collection trough 20 are fixedly connected to two sets of connecting plates 17. The bottom end of the connecting plate 17 is movably sleeved with a limiting slide post 18. Both ends of the limiting slide post 18 are fixedly connected to the inner wall of the base plate 1. The outer wall of the limiting slide post 18 is movably sleeved with a spring 19. The back of the spring 19 is attached to the connecting plate 17.

[0025] The slag collection trough 20 is internally fitted with a slag discharge pusher 23, and the top of the slag discharge pusher 23 is fixedly connected with a connecting rod 22. A slag discharge port is opened on one side of the slag collection trough 20, and a guide groove 12 is fixedly connected to the outer wall of the slag discharge port.

[0026] When the embossing roller 6 is embossing the packaging bag, some plastic debris will inevitably stick to its surface. As the embossing roller 6 continues to rotate, the debris will gradually rotate to the side closer to the scraper 21. At this time, under the influence of the elastic potential energy of the spring 19, the connecting plate 17 is pushed on the surface of the limiting slide post 18 towards the side where the embossing roller 6 is located, so that the protruding end of the scraper 21 at the top is in close contact with the surface of the embossing roller 6. The tip of the scraper 21 can scrape off the debris stuck to the surface of the embossing roller 6. At the same time, the scraped debris will fall down the surface of the scraper 21 into the inside of the debris collection trough 20, thereby achieving effective collection of debris. When the embossing roller 6 rolls the packaging bag again, it can always keep the embossed surface clean, ensuring that the embossed pattern is complete and clear, thus ensuring the production quality of the vacuum packaging bag.

[0027] Once a certain amount of debris has been collected inside the slag collection trough 20, the operator only needs to gently pull the connecting rod 22 to move it smoothly inside the slag collection trough 20. The slag discharge pusher 23 at the bottom of the connecting rod 22 will move accordingly, pushing the debris inside the slag collection trough 20 towards the side with the slag discharge port. Finally, these debris will smoothly move into the guide groove 12 through the slag discharge port, completing the cleaning of the residue. This not only effectively solves the problem of debris accumulation on the surface of the embossing roller 6, but also greatly improves production efficiency, reduces equipment failures and defect rates caused by debris accumulation, reduces the labor intensity of manual maintenance, and improves the automation level of the entire production process, providing a strong guarantee for the high-quality and high-efficiency production of vacuum packaging bags.

[0028] Example 2

[0029] Based on Example 1, please refer to Figures 1 to 4As shown, the flattening mechanism includes four sets of uprights 3. The bottom ends of the four sets of uprights 3 are all fixedly connected to the base plate 1. Two sets of flattening shafts 14 are provided on opposite sides of the four sets of uprights 3. One set of flattening shafts 14 has fixed sleeve blocks 16 fixedly connected to both ends of one set of flattening shafts 14, and the other set of flattening shafts 14 has movable sleeve blocks 15 fixedly connected to both ends of the other set of flattening shafts 14. The top of each movable sleeve block 15 is fixedly connected to a second spring 24. The top of the second spring 24 is fixedly connected to a limiting top plate 13. The bottom end of the limiting top plate 13 is fixedly connected to two sets of uprights 3. The inner wall of the second spring 24 is movably sleeved with the uprights 3.

[0030] Before the rolling process, the packaging bag first passes through the inner side of two sets of flattening shafts 14. These two sets of flattening shafts 14 perform a fine flattening treatment on the packaging bag. Through this pretreatment, the packaging tape can remain flat before entering the rolling stage, effectively avoiding the impact of wrinkles on the subsequent embossing quality and packaging effect. The elastic potential energy of spring 24 pushes the two sets of flattening shafts 14 to fit tightly against the surface of the packaging tape, ensuring the stability and reliability of the flattening process, improving the flatness of the packaging bag, and enhancing the automation and precision of the entire production process. Through the elastic adjustment of spring 24, the flattening shafts 14 can adapt to packaging tapes of different thicknesses and materials, thereby achieving more flexible production operations.

[0031] The support plate 4 has an internal movable groove, and an adjustment lifting block 10 is movably sleeved inside the movable groove. A transmission shaft 9 is fixedly connected to the opposite side of the adjustment lifting block 10, and a fitting roller 8 is movably sleeved on the outer wall of the transmission shaft 9.

[0032] The bottom end of the adjusting lifting block 10 is movably fitted with a threaded rod 11, and the outer wall of the threaded rod 11 is threadedly connected to the base plate 1.

[0033] By rotating the threaded rod 11, the position of the threaded rod 11 at both ends of the base plate 1 is adjusted, which drives the adjusting lifting block 10 to move up and down, thereby changing the height of the transmission shaft 2 9. Since the surface of the transmission shaft 2 9 is fitted with the bonding roller 8, the height of the bonding roller 8 also changes accordingly. The height adjustment can adapt to the thickness of different packaging bags and the required clamping force, thereby finely adjusting the embossing depth applied by the embossing roller 6 on the packaging bag. The adjustability not only improves the versatility and flexibility of the equipment, but also ensures the consistency and high quality of the embossing effect, meeting the personalized needs of different products.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
