[0003] Because the gluing sheet is easy to wear or the rubber roller is also worn during the long-time operation of the equipment, when worn, the gap between the gluing sheet and the rubber roller cannot guarantee the designed requirement of 0.05mm gap, when the gap is too large, the gluing plate will not take the glue liquid on the surface of the rubber roller, resulting in no glue point or too small glue point on the trademark paper, at this time, small box pasting is not firm or trademark paper is scattered, quality defects, maintenance personnel will re-adjust the gap between the gluing sheet and the rubber roller, because the original gluing sheet is a whole, there are three gluing sheets on the whole gluing plate, but the wear degree of each gluing sheet is different, and the wear degree of the corresponding rubber roller is also different, during the adjustment process, two gluing sheets and rubber rollers may reach the requirements, but one of them cannot meet the requirements, and the original gluing sheet has no limiting groove during radial adjustment, which causes the gluing sheet to be easy to skew during adjustment.

[0004] As described above, the original trademark paper gluing sheet cannot realize the individual adjustment of each gluing sheet, and is easy to skew during radial adjustment, a large amount of time is needed during the adjustment of the gluing sheet, when one of the three gluing sheets cannot meet the requirements, a new gluing sheet or a new rubber roller needs to be replaced, which wastes a large amount of spare parts, and a large amount of time is needed to adjust after replacing the gluing sheet and rubber roller, which seriously affects the effective operation rate of the equipment, and increases the consumption of spare parts cost.
