Description

Technical Field

[0001] The utility model belongs to the technical field of labeling equipment, and particularly relates to a label pasting device for the surface of a carton. Background Technique

[0002] Sticking labels on packaging boxes is a common packaging identification method. Common application fields include logistics and transportation, retail, food and beverage industry, pharmaceutical industry, electronic products, chemical products, etc. Labeling of packaging boxes not only helps with product identification and tracking but also provides legally required information, enhances brand image, and improves customer experience. With the development of automated labeling technology, the labeling process has become more efficient and accurate.

[0003] There are various forms of labeling for packaging boxes, which can be selected according to factors such as packaging requirements, automation level, and labeling position. Common labeling forms include flat labeling, circumferential labeling, top or bottom labeling, multi - surface labeling, double - layer labeling, intelligent labeling, etc. Selecting the appropriate labeling form requires considering the design of the packaging box, labeling method, label characteristics, and user identification needs.

[0004] In the prior art, some packaging cartons are labeled using labeling equipment after production and processing, but relatively costly camera positioning equipment needs to be set up to prevent the labels from being pasted crookedly. Therefore, the process of pasting labels on most existing cartons is generally still manually operated. When pasting, due to the different flatness of the cartons, the pasting effect of the labels has certain differences, and the efficiency is slow, or the pasting positions are inconsistent, affecting the identification effect of the labels.

The third transmission member 35 is connected to the feeding assembly 31 through a second belt group, and the fourth transmission member 36 is connected to the moving assembly 33 through a third gear group. The feeding assembly 31 includes a set of mounting plates 312, positioning rods 311, positioning plates 313, and a reel group 314. The positioning rods 311 are respectively installed on the tops of the set of mounting plates 312 through card slots. A plurality of second mounting holes and third mounting holes are respectively provided on two opposite surfaces of the set of mounting plates 312.

When the moving assembly 33 is driven by the fourth transmission member 36 and moves upward in the vertical direction, the first gear is meshed with the rack and the first gear drives the transmission rod to rotate so that the reel group 314 rotates to wind the material, enabling the label 5 laid flat on the positioning plate 313 to move towards the pasting plate 321 of the adsorption assembly 32 for the pasting plate 321 to adsorb the forward-moving label 5. When the moving assembly 33 is driven by the fourth transmission member 36 and moves downward in the vertical direction, the label 5 on the pasting plate 321 is pasted on the cardboard box 4, and at this time the rack is not connected to the first gear, so that the reel group 314 of the third transmission member 35 does not rotate, and the roll-shaped label 5 does not move forward and waits for the next upward movement command of the rack driven by the moving assembly 33.

The connecting spring 324 is installed on both sides of the positioning roller 323. The positioning roller 323 is installed directly above the positioning plate 313 and positioned on the upper surface of the label 5. By adjusting the tension of the rolled label 5 pulled by the reel group 314 using the positioning roller 323, the label 5 is flattened and laid flat on the positioning plate 313, facilitating the sticking plate 321 on the adsorption assembly 32 to adsorb it through air venting of the air holes. The sticking plate 321 can be a rectangular plate with a certain thickness. Air holes are provided on the bottom surface of the sticking plate 321 to facilitate the pneumatic component connected to the first connection hole on the top surface to suck or blow air through the air receiving pipe 322.
