The working principle of the labeling machine is a device that pastes rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products or prescribed packaging. The labeling equipment is used in various industries such as beverages, daily chemicals, food, medicine, and petrochemicals. Labeling of products such as product packaging containers and boxes. With the development of the times, Bogao Logo, as a well-known labeling machine manufacturer at home and abroad, provides product technical support and customized solutions that are synchronized with the world. It has gradually moved from the backward situation of manual and semi-automatic labeling to being occupied by automated high-speed labeling machines. The pattern of the market. 1. The working principle of the labeling machine The beginning of the working process is to feed the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device (clamping conveying mechanism) on the labeling machine separates the labeled items by a fixed distance, and pushes the labeled items to move along the conveyor belt. The mechanical system of the labeling machine includes a drive wheel and a labeling machine. Wheel, and a reel. The driving wheel drags the label tape intermittently, and the label tape is pulled out from the reel. At the same time, the labeling wheel will press the labeling tape on the article to be pasted by the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to each other on the label tape, the label tape must continue to start and stop. The label is affixed to the affixed article when the labeling wheel and the affixed article move at the same speed. When the conveyor belt reaches a certain position (sensor), the label belt drive wheel will accelerate to a speed matching the conveyor belt, and after the label is applied, it will decelerate to a stop. Since the label may slide, there is a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor. During the deceleration phase of the label tape, the drive wheel will readjust its position to correct any position errors on the label tape. 2. Classification of labeling machines Due to the different types of labeling objects and the different material shapes of the labels themselves, the labeling requirements are also different. Therefore, in order to meet the labeling requirements under different conditions, there are different types and varieties of labeling machines. 1. According to the product type: vertical round bottle labeling machine, flat labeling machine, fixed-point positioning labeling machine, bottom labeling machine, inclined horizontal labeling machine, double-sealing labeling machine, square bottle rotary labeling machine , High-speed double-side labeling machine, single-side labeling machine, high-speed round bottle labeling machine, corner online printing labeling machine, real-time printing labeling machine, direct-sticking online printing labeling machine, air blowing online printing Labeling machine, contact online printing labeling machine, end face labeling machine, tube labeling machine; 2. According to the degree of automation: automatic, automatic, semi-automatic and manual labeling machines; 3. According to the realization of different labeling machines Labeling function: flat labeling machine, side labeling machine and circumferential labeling machine; 4. According to the running direction of the container: vertical labeling machine and horizontal labeling machine; 5. According to the labeling process feature: pressure type Labeling machine, rolling labeling machine, rolling labeling machine, brush stroke labeling machine; 6. According to different adhesive coating methods: self-adhesive labeling machine, paste labeling machine (on Paste labeling machine, glue labeling machine) and hot melt adhesive labeling machine; 7. Types of labels: sheet label labeling machine, roll label labeling machine, hot adhesive label labeling machine and sensor Pressure labeling machine and shrinking cylindrical label labeling machine; 8. According to the length of the label: single-sided labeling machine, double-sided labeling machine, end labeling machine, three-sided labeling machine and multi-sided labeling machine; three , The scope of application of the labeling machine, according to the classification suitable for different labeling functions, the scope of application of the labeling machine is described. Boxes, books, plastic cases, etc., there are two methods of rolling and sticking. The selection is mainly based on efficiency, precision and bubble requirements. 2. The round bottle labeling machine is suitable for labeling or filming on the circumferential surface of cylindrical and conical products, such as glass bottles, plastic bottles, etc., which can realize the functions of circumference, half circumference, circumference double-sided, circumference positioning labeling, etc. There are mainly two ways of vertical labeling and horizontal labeling. 3. The side labeling machine is suitable for labeling or filming on the side plane and side arc surface of the workpiece, such as cosmetic flat bottles, square boxes, etc., can be equipped with round bottle labeling equipment, and realize round bottle labeling at the same time. 4. The end face labeling machine is suitable for labeling lipstick, lipstick, etc. 5. The square bottle rotary labeling machine is suitable for labeling machines on milk bottles and quadrilateral bottles.
