Labeling machine is a device that sticks rolled self-adhesive paper labels on PCB, products or specified packaging, and is widely used in the field of modern packaging. The main function of the labeling machine is to apply the label evenly and flatly on the items to be labeled to ensure the quality and efficiency of labeling.
The main components of the labeling machine include:
Unwinding wheel: a passive wheel used to place roll labels, equipped with a friction brake device with adjustable friction force, to control the roll speed and tension, and to maintain smooth paper feeding.
Buffer wheel: connected to the spring, can swing back and forth, absorb the tension of the roll material when starting, keep the material in contact with each roller, and prevent the material from breaking.
Guide roller: consists of two upper and lower parts, which guide and position the roll material.
Drive roller: consists of a group of active friction wheels, usually one is a rubber roller and the other is a metal roller, which drives the roll material to achieve normal labeling.
Rewinding wheel: an active wheel with a friction transmission device, which rewinds the base paper after labeling.
Peeling plate: When the backing paper changes direction through the peeling plate, the label is easy to be released and separated from the backing paper, so as to achieve contact with the labeling object.
Labeling roller: The label separated from the backing paper is evenly and flatly applied to the object to be labeled
Classification of labeling machines and their application scenarios
Labeling machines can be classified according to different needs:
Fully automatic labeling machine: Suitable for assembly line operation, can automatically position, peel and apply labels, widely used in food and beverage, pesticide chemicals, medicine and health care industries
Rotary labeling machine: Suitable for round or square cans and bottles, paper tubes, etc., and can achieve full or partial circumference labeling
Linear labeling machine: Suitable for items arranged in a straight line, easy to operate, suitable for small and medium-sized enterprises
Flat labeling machine: Suitable for various flat packaging, such as boxes, bottles, etc., with high efficiency and precision
