Description

Technical Field

[0001] This utility model relates to the field of labeling technology, specifically a modular hot glue labeling station combining spray adhesive and roller adhesive. Background Technology

[0002] Existing labeling equipment uses adhesive to bond the labels to both ends. Specifically, adhesive is first applied to the front edge of the label using a roller assembly. After application, the label is fed to the bottle by a vacuum drum assembly, adhering the front edge to the bottle. Then, the bottle rotates, wrapping the label around it. During this wrapping process, the roller assembly simultaneously applies adhesive to the back edge of the label. Finally, the front edge of the label is firmly attached to the bottle, while the back edge overlaps and adheres to the front edge. However, this existing labeling method requires high precision in the labeling equipment and precise adjustment of the adhesive supply, making it difficult to operate and affecting the labeling pass rate. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular hot glue marking station that combines spraying and rolling.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A modular hot glue labeling station combining spraying and rolling includes a mounting base, a support frame on the mounting base, a label tray assembly positioned opposite the rear end of the support frame, an automatic label receiving assembly positioned on the support frame at the front center of the label tray assembly, a label tensioning roller assembly positioned on the support frame in front of the automatic label receiving assembly, a label correction device positioned on the support frame in front of the label tensioning roller assembly, a pressure roller assembly positioned on the support frame in front of the label correction device, a label cutting drum assembly positioned on the support frame in front of the pressure roller assembly, a glue roller assembly positioned on the support frame opposite to the label cutting drum assembly, a glue tank assembly connected to one side of the glue roller assembly, a vacuum drum assembly positioned on the support frame between the label cutting drum assembly and the glue roller assembly, and a glue spraying assembly positioned on the support frame outside the glue roller assembly, with the glue nozzle of the glue spraying assembly facing outward towards the packaging bottle, and a glue spraying box connected to the glue spraying assembly positioned on one side of the mounting base.

[0005] Compared with the prior art, the present utility model adopting the above technical solution has the following outstanding features: The first layer of adhesive is applied by spraying glue onto the packaging bottle using a spraying assembly.

A label-cutting drum assembly 8 is provided on the support frame 2 in front of the label-pressing roller assembly 7. A rubber roller assembly 9 is provided on the support frame 2 opposite to the label-cutting drum assembly 8. A glue box assembly 10 is connected to one side of the rubber roller assembly 9. A vacuum drum assembly 11 is provided on the support frame 2 between the label-cutting drum assembly 8 and the rubber roller assembly 9. A glue spraying assembly 12 is provided on the support frame 2 outside the rubber roller assembly 9. The glue outlet 13 of the glue spraying assembly 12 faces the outer packaging bottle direction. A glue spraying box 14 connected to the glue spraying assembly 12 is provided on one side of the mounting base 1.

[0015] In practice, the glue spraying assembly 12 includes a base plate 15 fixed to the support frame 2, a base 16 is provided on the base plate 15, a sliding seat 17 is slidably provided on the base 16, a support column 18 is vertically provided on the sliding seat 17, and a glue dispensing machine 19 is provided on the support column 18.

[0016] The base plate 15 has an arc-shaped plate structure, and an arc-shaped groove 20 is provided at the outer end of the base plate 15. The base 16 is adjustablely mounted on the base plate 15 through the arc-shaped groove 20. Mounting holes that match the position of the arc-shaped groove 20 can be opened on the base 16. After the base 16 is adjusted to the correct position, bolts are inserted into the arc-shaped groove 20 and the mounting holes for fixing.

[0017] A sliding rod 21 is arranged opposite to the base 16, and a slider 22 is slidably arranged on the sliding rod 21. A screw 23 is rotatably arranged on the base 16 between the sliding rods 21, and the screw 23 is threadedly connected to the slider 22. A sliding seat 17 is arranged on the slider 22.

[0018] The support column 18 includes a lower support column, with a slot on one side of the top of the lower support column, and an upper support column is installed in the slot. An elongated hole can be made in the upper support column, and an installation hole matching the position of the elongated hole can be made in the slot of the lower support column. After the height is adjusted, bolts are inserted into the elongated hole and the installation hole for fixation.

[0019] The bottom of the lower support column is provided with a circular base plate, and an array of arc-shaped holes are arranged on the circular base plate. The lower support column is adjustablely mounted on the sliding seat 17 through the arc-shaped holes 24. Mounting holes that match the position of the arc-shaped holes 24 can be opened on the sliding seat 17. After rotating the support column 18 to adjust the position, bolts are inserted into the arc-shaped holes 24 and the mounting holes for fixing.

[0020] In practice, one roll of labels is installed in each of the two label tray assemblies 3, one for backup and one for use. The front end of the backup label is pulled out to the position of the automatic label receiving assembly 4. The label to be labeled passes through the automatic label receiving assembly 4, bypasses the label tension roller group 5, passes through the label correction device 6 and the pressure roller assembly 7, and enters the label cutting drum assembly 8. The label cutting drum assembly 8 cuts the label into individual labels according to the set size and sends the individual labels to the vacuum drum assembly 11. The vacuum drum assembly 11 adsorbs the individual labels and then adheres them to the roller surface of the adhesive roller assembly 9, and is then vacuum-driven. The drum assembly 11 continues to feed individual labels; the dispensing machine 19 sprays glue onto the packaging bottle to be labeled. When the packaging bottle moves to the position of the vacuum drum assembly 11, the front side of the individual label contacts the glue on the packaging bottle and is pasted; the glue roller assembly 9 rolls glue on the rear side of the individual label. As the packaging bottle rotates and is conveyed, the rear side of the label overlaps and is pasted on the front side to complete the labeling; when the label being labeled is about to be used up, the automatic label receiving assembly 4 connects the spare label with the label that is about to be used up, so as to achieve uninterrupted labeling.

[0021] The solution provided by this utility model uses a spray adhesive assembly to spray adhesive onto the packaging bottle in the first stage. When the packaging bottle moves to the position of the vacuum drum assembly, the front end of the label contacts the bottle body, and the label adheres to the packaging bottle. The second stage adhesive is rolled onto the rear side of the label by a glue roller assembly. As the packaging bottle rotates, the rear side of the label overlaps and adheres to the front side, completing the labeling process. This improves the existing two-stage roller-coating labeling method to a first-stage spray adhesive followed by a second-stage roller-coating method, reducing the requirements for labeling equipment accuracy and glue supply adjustment, and improving the labeling qualification rate. The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
