Description

Technical Field

[0001] The utility model relates to the technical field of packaging printing, in particular to a printing and labeling device. Background Art

[0002] An automatic labeling machine is a device that uses adhesive to stick paper or metal foil labels on a specified packaging container. For example, the prior art publication number CN102745539B discloses a labeling device, which includes: a base for conveying base paper, a reel for placing a roll formed by a self-adhesive label tape, a reel for rewinding the release paper tape for peeling off the chip / pad, and a tensioning device and a peeling plate that sequentially constrain the conveying path of the release paper tape between the reel and the reel. The present invention proposes a labeling device that realizes the automatic compounding between the RFID chip / pad and the base paper during the production of RFID electronic tags. The compounding speed is fast and the effect is good, which greatly improves the production efficiency and can be coordinated with the existing production line. It has a simple structure, reliable operation, low cost, not prone to failure, and convenient adjustment. It can be used for the production of RFID electronic tags of different specifications and has good practical value.

[0003] The principle is mainly to peel the label off the label tape through the peeling plate. In the actual working process, the peeling plate needs to be rhythmically translated to avoid, so that the pressure plate can move down to press the label tightly and stick it on the packaging surface to improve the sticking firmness. That is, the translation distance of the peeling plate must be greater than the length of the label. However, when the label is relatively long, if the displacement distance of the peeling plate is increased blindly, the label tape will become loose and the sensor will not be able to identify the label position well, resulting in uncontrollable labeling position. Based on this, the existing labeling machine has the problem of difficulty in sticking long labels, which needs further improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a printing and labeling device to solve the problems raised in the above background technology.

[0007] A telescopic driving mechanism is fixedly installed on the front of the mounting seat, and a pressing plate is fixedly installed on the telescopic end of the telescopic driving mechanism.

[0009] In some embodiments, the telescopic drive mechanism includes a first cylinder, which is fixedly connected to the mounting seat. A telescopic plate is slidably mounted on the surface of the first cylinder. The first cylinder drives the telescopic plate to move up and down to achieve a single-stage downward pressing action of the pressure plate.

[0013] A damper is fixedly installed on the back of the sliding seat, and the unwinding disk is detachably assembled on the rotating end of the damper. The damper provides rotational resistance for the rotation of the unwinding disk and provides a certain resistance for the retraction and release of the label tape to prevent the unwinding disk from rotating inertia and causing the label tape to become loose.

[0029] Specifically, a baffle 15 is fixedly installed on the lower surface of the sliding seat 2.
