Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and in particular to a label conveying device for self-adhesive label stations. Background Technology

[0002] The stability of the label conveying device in an adhesive labeling station is crucial for ensuring the smooth and accurate application of labels to containers. To improve label conveying stability and effectively reduce noise, existing patent number CN212891382U, entitled "Labeling Conveying Mechanism on Labeling Station of Adhesive Labeling Machine," proposes a label conveying mechanism using a synchronous belt mechanism for the power unit. However, the synchronous belt is prone to loosening during use. Loosening can cause the first and second power rollers to rotate out of sync, leading to label breakage. Therefore, a tensioning mechanism is required, and the tension of the synchronous belt needs to be checked and adjusted periodically using the tensioning mechanism, making the operation cumbersome. Summary of the Invention

[0003] To address the above problems, embodiments of the present invention provide a label conveying device for self-adhesive label stations.

[0004] In one aspect of this invention, a label conveying device for self-adhesive label stations is provided, comprising a bottom fixing plate, a drive motor fixed on the bottom surface of the bottom fixing plate, the output axis of the drive motor passing upward through the bottom fixing plate and coaxially connected to a rubber label conveying roller, a top fixing plate being arranged opposite to the bottom fixing plate, the top fixing plate and the bottom fixing plate being fixedly connected by a connecting rod; a label feeding and pressing roller and a label receiving and pressing roller are respectively arranged between the bottom fixing plate and the top fixing plate and on both sides of the rubber label conveying roller, the label feeding and pressing roller and the label receiving and pressing roller being arranged parallel to the rubber label conveying roller and in contact with the rubber label conveying roller.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: a rubber label conveying roller is directly driven by a drive motor, and the label feeding and receiving rollers on both sides are pressed against the rubber label conveying roller. The rotation of the rubber label conveying roller can simultaneously complete the label feeding and receiving work, ensuring the consistency of label feeding and receiving. The overall structure is simple and the label conveying is more stable.

[0006] Optionally, a first redirecting roller and a second redirecting roller are respectively provided between the bottom fixed plate and the top fixed plate and on both sides of the label feeding and pressing roller. The first redirecting roller, the label feeding and pressing roller, and the second redirecting roller form a label feeding channel with the rubber label conveying roller.

[0007] Optionally, a third redirecting roller and a fourth redirecting roller are respectively provided between the bottom fixed plate and the top fixed plate and on both sides of the label receiving and pressing roller. The third redirecting roller, the label receiving and pressing roller, and the fourth redirecting roller form a label receiving channel with the rubber label conveying roller.

[0008] Optionally, two sets of elongated holes are provided at the relative positions of the bottom fixing plate and the top fixing plate. The cylinder shafts of the label feeding and pressing rollers and the label receiving and pressing rollers are respectively placed in the two sets of elongated holes. A stepped hole is provided between each elongated hole and the outer side of the bottom fixing plate or the top fixing plate. A tightening mechanism is provided in the stepped hole to tighten the label feeding and pressing rollers or the label receiving and pressing rollers towards the rubber label conveying roller.

[0009] Optionally, the tightening mechanism includes a sleeve placed in a stepped hole, a push rod installed inside the sleeve, one end of the push rod abutting against the cylinder shaft, a tightening cap fitted on the outside of the sleeve, and a tightening spring installed inside the sleeve, with both ends of the tightening spring abutting against the tightening cap and the push rod respectively.
