Detailed Description

The invention will be described in further detail with reference to the drawings and preferred embodiments.

As shown in fig. 1 and 2, the label buffer mechanism in the labeling and conveying device is characterized in that: the main shaft 1 can rotate under the driving of a driving mechanism, a guide cylinder body 2 is arranged outside the main shaft 1, the guide cylinder body 2 is divided into a plurality of mutually independent arc-shaped guide plates 21, each arc-shaped guide plate 21 is movably supported on one guide rod 3, and each guide rod 3 is fixed on the main shaft 1 and is arranged along the radial direction of the main shaft 1. In the present embodiment, all the guide rods 3 are mounted on the upper end portion of the main shaft 1. In the embodiment, the guide cylinder 2 is uniformly divided into eight circular arc guide plates 21, and the eight circular arc guide plates 21 are uniformly arranged outside the main shaft 1 at intervals.

The outer end of each guide rod 3 is provided with a limiting mechanism for blocking the arc-shaped guide plate 21. In this implementation, stop gear on every guide bar 3 is nut 31, and nut 31 screw thread fixed connection is at the outer tip of guide bar 3, and every nut 31 homoenergetic card keeps off the circular arc deflector 21 on the corresponding guide bar 3. The nut 31 is used as a limiting mechanism, so that the structure is simple and practical, and the manufacturing is convenient.

Every circular arc deflector 21 homoenergetic is at guide bar 3 round trip movement, and in this embodiment, all seted up the mounting hole on every circular arc deflector 21, all supported on guide bar 3 through the mounting hole activity on every circular arc deflector 21. All be provided with a set of counter weight mechanism between every arc deflector 21 and the main shaft 1 at least, counter weight mechanism include: the top of the counterweight block 4 is hinged with a first connecting rod 5 and a second connecting rod 6, the other end of the first connecting rod 5 is hinged on the main shaft 1, and the other end of the second connecting rod 6 is hinged on a corresponding circular arc-shaped guide plate 21; all the counter weights 4 have the same weight, all the first connecting rods 5 have the same length, and all the second connecting rods 6 have the same length. In this embodiment, two sets of counterweight mechanisms are vertically and alternately arranged between each circular arc-shaped guide plate 21 and the main shaft 1, and the upper and lower first connecting rods 5 and the upper and lower second connecting rods 6 of the two sets of counterweight mechanisms between each circular arc-shaped guide plate 21 and the main shaft 1 are respectively arranged in parallel.

The connection structure between the balancing weight 4 and the connecting rod in each balancing weight mechanism comprises: the top of balancing weight 4 is provided with articulated shaft 41, thereby one of first connecting rod 5 and articulated shaft 41 are connected sets up opening 51 and forms a pair of first connecting portion 52, has seted up the connecting hole on a pair of first connecting portion 52, and a pair of first connecting portion 52 passes through the connecting hole suit on articulated shaft 41, and the one end that second connecting rod 6 and articulated shaft 41 are connected also passes through the connecting hole suit at articulated shaft 41, and the one end that second connecting rod 5 and articulated shaft 41 are connected is located the opening 51 of a pair of first connecting portion 52.

In operation, the buffer mechanism for the labels in the labeling and conveying device described in this embodiment is installed between the unwinding mechanism 7 and one guide roller 8, and the labels on the label roll 10 are unwound and conveyed to the buffer mechanism by the unwinding mechanism 7, and then are guided out by the guide roller 8. When the mark is pasted, the main shaft 1 is driven by the driving mechanism to rotate, and the balancing weight can drive the corresponding arc-shaped guide plate 21 to move to a corresponding position on the guide rod 3 under the action of centrifugal force. The larger the rotation speed of the spindle 1 is, the larger the centrifugal force of the counterweight block is, and the farther the circular arc-shaped guide plate 21 is from the spindle 1, otherwise, the closer the circular arc-shaped guide plate 21 is to the spindle 1.

Therefore, by controlling the rotation speed of the spindle 1, the distance between the circular arc guide plate 21 and the spindle 1 can be adjusted, thereby adjusting the buffer length of the label. When the unwinding speed of the unwinding mechanism 7 is reduced, the rotating speed of the main shaft 1 is correspondingly reduced, so that the circular arc-shaped guide plate 21 moves inwards, and the buffer length of the label can be reduced; when the unwinding speed of the unwinding mechanism 7 is increased, the rotating speed of the spindle 1 is correspondingly increased, so that the circular arc-shaped guide plate 21 moves outwards, and 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, so that the adjustment of the buffer length of the label is very convenient, and the adjustment flexibility is greatly improved.

On the premise that the unwinding speed of the unwinding mechanism 7 is not changed, the rotating speed of the spindle 1 is correspondingly increased, so that the arc-shaped guide plate 21 has a tendency of moving outwards, and the tension of the label can be effectively increased.

In addition, because the tension that can bear of the label base paper of different materials is different, consequently, through the rotational speed of adjusting main shaft 1, can make buffer gear be applicable to the buffering of the label of different materials base paper and carry, buffer gear's suitability is good.
