How do I affix a complex product logo? Is it hand-applied? This article will show you.
Labeling machine, pastes rolls of self-adhesive paper labels (paper or metal foil) PCB, products or equipment on packaging. Labeling machine is an indispensable component of modern packaging.
At present, the types of labeling machines produced in China are gradually increasing, and the level of technology has improved considerably. It has changed from the backwardness of manual and semi-automatic labeling to a model where automatic high-speed labeling machines occupy most of the market .
Labeling rate: the number of packaging containers labeled according to the labeling requirements (single or multiple labels) and the percentage of the total number of packaging containers inspected.
Damage rate: The percentage of labels damaged by the labeling machine during the labeling process compared to the total number of labels consumed during the inspection of packaging containers for labeling.
Positive labeling rate: the percentage of the number of positive labeled packaging containers to the total number of packaging containers inspected.
Advantages of labeling machines:
Wide range of application, can meet the full circumference of the round bottle labeling or semi-circular labeling, bottle labeling between the simple switching, easy to adjust.
Labeling high degree of coincidence, the label belt around the use of correction mechanism, the label belt does not deviate, label part of the x / y / z three directions and tilt a total of eight degrees of freedom adjustable, no dead angle adjustment, label coincidence high.
The working principle of the labeling machine:
The working process starts with the boxes being fed to the labeling machine at a constant speed on the conveyor belt. A mechanical fixing device separates the boxes at a fixed distance from each other and pushes the boxes in the direction of the conveyor belt. The mechanical system of the labeling machine consists of a drive wheel, a labeling wheel and a reel. The drive wheel intermittently drags the labeling tape along. The label belt is pulled from the reel. At the same time, the label tape is pressed onto the box by the labeling wheel. The reel is controlled by an open-loop displacement for maintaining the label band tension. As the labels are tightly attached on the label belt, the belt must be started and stopped continuously.
When the labeling wheel is moving at the same speed as the box, the label is applied to the box. When the belt reaches a specific position, the label belt drive wheel will accelerate to a speed matching the belt and then decelerate to a stop.
As the label belt may slide, there is a registration mark on it to ensure that each label is placed correctly. The registration marks are read by sensors. During the deceleration phase of the label belt, the drive wheel will reposition itself to correct any misplacement on the label belt.
Labeling machine application industries:
Uses:Automatic labeling of products on their circumferential surfaces for automatic labeling;
Function:Improve product labeling efficiency, accurate position, good quality and high stability; avoid a series of problems such as low manual labeling efficiency, tilted pasting, uneven pasting thickness and wrinkles, effectively reduce paste waste, reduce labeling labour costs, improve product labeling aesthetics and improve the overall competitiveness of products.
Scope of application: Suitable for packaging bottles, bags, plastic and other materials of any industry.
Applicable labels: Paper labels (paste).
Applicable products: Products that need to be labeled with paste on the circumferential surface.
Widely used in the food, daily chemical, pharmaceutical and alcohol industries.
Application examples:Bamboo, beer, pesticide bottles, etc.
