Labeling machine is an indispensable part of modern packaging. It is a device for pasting rolled self-adhesive paper labels (paper or metal foil) on PCB, products or designated packages.
1, standard
When the label is attached to the packaging container, the deviation between the center line of the label and its theoretical position is within the specified range, which is called a positive label. If there are multiple labels on the same packaging container, their deviations from the theoretical position should be calculated according to the above definition, and they should all be within the specified range.
2. Marking rate
According to the label requirements, the number of packaging containers labeled (single label or multiple labels) accounts for the percentage of the total number of packaging containers inspected.
3. Loss rate
In the labeling process, the number of labels damaged by the labeling machine accounts for the percentage of the total number of labels consumed when labeling the inspected packaging container.
4. Positive standard rate
In the inspected packaging containers, the number of standard packaging containers accounts for the percentage of the total number of inspected packaging containers.
2. What are the types of labeling machines?
1, by label material
(1) The hot melt adhesive labeling machine uses plastic labels and bopp materials. Its label refers to products, such as Master Kong mineral water, but the seam of the label is a little sticky, and there is no sticking in other places. This kind of equipment is mostly made into rotary labeling, which is very fast, so it can be used for labeling beverage products such as mineral water and cola. Of course, the price is high.
(2) Self-adhesive labeling machine is the mainstream labeling machine in the market, using self-adhesive labels. Whenever you take a packaged item, you can see a product with a self-adhesive label. The application industry covers almost the whole industry.
(3) Paste labeling machine is also called paste labeling machine. The label material is paper material, and the paste is evenly coated on the label paper through the paste brushing mechanism. For example, the paper labels on the doors of our soy sauce bottles and Erguotou bottles are all pasted by a pasting and labeling machine.
2, according to the labeling machine modeling points
(1) linear labeling machine, that is, the conveyor belt is straight and the product is straight. It is also the most widely used labeling machine in the market, with simple operation and affordable price.
(2) The rotary labeling machine is faster, which is used for quick labeling of daily chemicals and wine industry, but the self-adhesive labeling machine can also be distinguished by heat.
(3) Semi-automatic labeling machine, the biggest feature is that it can't dock the production line and needs manual operation. Manually hold the product to be labeled and put it into the labeler station, and then touch the switch button to drive labeling. Mainly for small batch products or automatic labeling difficulties.
(4) The automatic labeling machine is connected with the production line without manual operation, and the product automatically enters the labeling station, labels are detected, a bar code traceability system is automatically added, and is automatically transmitted to the next working procedure. In the environment of high output and docking production line, automatic labeling machine is needed.
3. Main points of label content
(1) The fixed label content can be labeled with a common labeling machine.
(2) Variable labels need to be printed and labeled in real time, and real-time printed labels need to be printed and pasted on site, which is often used in express delivery industry, e-commerce industry, electronic products and other industries.
(3) Simple variable labels, such as production date, need to be labeled with a common labeling machine plus a coding machine or a inkjet printer.
4, according to the shape of the product label.
(1) round bottle labeling machine is characterized by high speed and high price, which is suitable for high-yield products.
(2) Rotary fixed-point labeling machine, suitable for all-round self-adhesive labeling of square containers such as beverages, medicines, mineral water and food.
(3) Labeling machines for circular products such as red wine and PET cans can adapt to the taper of small samples.
(4) Plane labeling machine, labeling plane products, such as cartons, boxes, charging treasures, etc.
(5) Side labeling machine, double-sided labeling machine for square bottles, round bottles and flat products.
5. Mark the table points
(1) corner labeling machine, where labels are covered at right angles on both sides, such as sealing labels, anti-counterfeiting labels and tamper-proof labels of color box packaging.
(2) Three-sided labeling machine, covering the front and left and right sides of square products, such as three-sided labeling of square oil drums.
(3) Four-sided labeling machine, which is used for labeling square products surrounded on all sides, such as labeling square toys and oil drums.
(4) The wire folding labeling machine is used to label thin tube products, such as wires, bellows, earphone wires, etc.
(5) The terminal labeling machine is used for labeling lipsticks and ointments.
