The structure of the automatic self-adhesive labeling machine mainly includes the following components:

1. Unwinding mechanism: It is a passive wheel, which is used to place the roll label. Usually equipped with a friction braking device with adjustable friction force, the purpose is to control the speed and tension of the reel and keep the paper feeding smoothly.

2. Buffer wheel: The coil spring is connected and can swing back and forth. The purpose is to absorb the tension force of the roll material when the device is started, keep the material in contact with each roller, and prevent the material from breaking.

3. Guiding mechanism: It is composed of upper and lower parts, which plays the role of guiding and positioning the reel material.

4. Traction mechanism: It consists of a group of active friction wheels. Usually one is a rubber roller and the other is a metal roller, and the backing paper passes between them; the automatic self-adhesive labeling machine cleverly utilizes the principle of the eccentric wheel, and uses two silicone sticks for traction, which improves the traction and reduces the material cost. The function is to drive the reel material to achieve normal labeling.

5. Rewinding mechanism: It is a driving wheel with friction transmission device, and its function is to rewind the bottom paper after labeling. The rotation of the paper delivery roller and the paper handling of the driving wheel do not interfere with each other, and the synchronous transmission is adjusted by the friction device.

6. Peeling plate: There is an angle at one end of the peeling plate (generally less than 30°), the purpose is to make the label easy to be labelled and separated from the backing paper when the backing paper changes direction through the peeling plate, so as to achieve contact with the labeling object.

7. Label covering mechanism: evenly and evenly apply the label separated from the backing paper to the item to be pasted.
