As shown in fig. 1, the labeling station of the self-adhesive labeling machine comprises: the label roll comprises a label roll 1, an unfolding mechanism 2, a label feeding mechanism, a stripping mechanism 3 and a winding mechanism 4 which are sequentially arranged along the running direction of labels. The labels to be applied are applied to a base paper and rolled into a roll, and the rolled labels are called label rolls 1. two label rolls 1 are usually placed at one label station for replacement. The unrolling mechanism 2 generally comprises a pair of unrolling power rollers and an unrolling driven roller, the unrolling power rollers are driven by a power mechanism, and the unrolling power rollers and the unrolling driven roller continuously unroll the base paper adhered with the labels on the label roll 1. The peeling mechanism 3 is used for peeling the label from the base paper. The winding mechanism 4 is used for winding the base paper peeled from the label into a roll shape.
The label feeding mechanism comprises a buffer conveying mechanism 5, a label feeding power roller group 6 and a label base paper recycling power roller group 7. The buffer conveyor 5 is arranged between the unwinding mechanism 2 and a guide roller 16.
Specifically, as shown in fig. 2, 3, and 4, the buffer conveyance mechanism 5 includes: the main shaft 51 is driven by a driving mechanism, a guide cylinder 52 is arranged outside the main shaft 51, the guide cylinder 52 is divided into a plurality of circular arc guide plates 521, in the embodiment, the guide cylinder 52 is uniformly divided into eight circular arc guide plates 521, and the eight circular arc guide plates 521 are uniformly arranged outside the main shaft 51 at intervals. Each circular arc-shaped guide plate 521 is movably supported on one guide rod 53, each guide rod 53 is fixed on the main shaft 51 and arranged along the radial direction of the main shaft 51, and all the guide rods 53 are installed at the upper end part of the main shaft 51. The outer end of each guide rod 521 is provided with a limiting mechanism for blocking the arc-shaped guide plate 521, in this embodiment, the limiting mechanism is a nut 531, the nut 531 is fixedly connected to the outer end of the guide rod 53 through threads, and each nut 531 can block the arc-shaped guide plate 521 on the corresponding guide rod 53. The nut 531 is used as a limiting mechanism, so that the structure is simple and practical, and the manufacture is convenient.
Every circular arc deflector 521 homoenergetic is at the guide bar 53 round trip movement, all is provided with a set of counter weight mechanism between every circular arc deflector 521 and the main shaft 51 at least, counter weight mechanism include: the top of the counterweight 54 is hinged with one end of a first connecting rod 55 and one end of a second connecting rod 56, the other end of the first connecting rod 55 is hinged on the main shaft 51, and the other end of the second connecting rod 56 is hinged on the corresponding circular arc-shaped guide plate 521; all of the weights 54 have the same weight, all of the first links 55 have the same length, and all of the second links 56 have the same length. In this embodiment, two sets of counterweight mechanisms are disposed between each circular arc-shaped guide plate 521 and the main shaft 51 at an interval from top to bottom. The upper and lower first links 55 and the upper and lower second links 56 of the two sets of counterweight mechanisms between each circular arc-shaped guide plate 521 and the main shaft 51 are respectively arranged in parallel.
In this embodiment, the buffer conveying mechanism 5 further includes a distance sensor disposed outside one of the guide rods 53, and the distance sensor is configured to detect a position of the circular arc-shaped guide plate 521 on the guide rod 53.
When the mark is pasted, the main shaft 51 rotates, and the counterweight block 54 drives the corresponding circular arc-shaped guide plate 521 to move to a corresponding position on the guide rod 53 under the action of centrifugal force. The greater the rotation speed of the spindle 51, the greater the centrifugal force of the counterweight 54, and the further away the circular arc-shaped guide plate 521 is from the spindle 1, whereas the closer the circular arc-shaped guide plate 521 is to the spindle 51.
Therefore, by controlling the rotation speed of the spindle 51, the distance between the circular arc guide plate 521 and the spindle 51 can be adjusted, thereby adjusting the buffer length of the label. When the unwinding speed of the unwinding mechanism 2 is reduced, the rotation speed of the spindle 51 is correspondingly reduced, so that the circular arc-shaped guide plate 521 is moved inward, and thus the buffer length of the label can be reduced. When the unwinding speed of the unwinding mechanism 2 is increased, the rotation speed of the spindle 51 is correspondingly increased, so that the circular arc-shaped guide plate 521 moves outward, and thus the buffer length of the label can be increased. When the label is pasted, the buffer length of the label can be correspondingly adjusted according to actual conditions, the adjustment of the buffer length of the label is very convenient, and meanwhile, the adjustment flexibility is greatly improved.
On the premise that the unwinding speed of the unwinding mechanism 2 is not changed, the rotating speed of the spindle 51 is correspondingly increased, so that the arc-shaped guide plate 521 has a tendency of moving outwards, and the tension of the label can be effectively increased.
In addition, because the different materials of the label base paper can bear different tensions, the buffer conveying mechanism 5 can be suitable for buffer conveying of labels of different materials of the base paper by adjusting the rotating speed of the main shaft 51, and the applicability of the buffer conveying mechanism 5 is good. The label moves under the guide of circular arc shape deflector 521 in buffering conveying mechanism 5, and operating stability improves greatly.
The arrangement of the distance sensor can monitor the position of the arc line guide plate 521 on the guide rod 52 in real time, and the rotation speed of the main shaft 51 is adjusted to ensure that the arc line guide plate 521 is located at the set position on the guide rod 53, so that the buffering length and the tension of the label can be accurately controlled.
