The working principle and classification of Fuzhou labeling machine-industry news

by:Zhongya Packaging      2022-05-27
1. The working principle of the labeling machine At the beginning of the working process, the box is fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes by a fixed distance and pushes the boxes along the conveyor belt. The mechanical system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The driving wheel drags the label tape movement intermittently, the label tape is pulled out from the reel, and the labeling wheel will press the label tape on the box after passing through 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 constantly start and stop. The principle of automatic labeling machine The label is attached to the box when the labeling wheel and the box move at the same speed. When the conveyor belt reaches a certain position, the label belt drive wheel will accelerate to a speed that matches the conveyor belt, and after the label is attached, it will decelerate to a stop. Since the label belt 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. Second, the five advantages of the labeling machine. Advantage 1: High performance and cost-effective. Someone once calculated an account: If a fully automatic labeling machine is 60,000, the service life is 10 years, and it only costs 500 yuan per month. The salary of ordinary employees is calculated at 2,000 yuan, and it needs 240,000 in ten years. As a result, the emergence of fully automatic labeling machines has brought huge benefits to the production packaging line. Advantage 2: Small size The automatic labeling machine has a small volume and floor space, which can save the cost of workshop infrastructure for pharmaceutical companies, and it can also be matched with a filling machine to form a complete production line. Advantage 3: Wide range of applications As mentioned above, the automatic labeling machine is widely used in medicine, food, daily chemical industry and other industries, and even cosmetics can be labelled by the automatic labeling machine, including bar code, two-dimensional Code, anti-counterfeiting label, etc. According to industry insiders, the emergence of fully automatic labeling machines has simplified the previous production process. Advantage 4: Long service life The automatic labeling machine is generally composed of 304 stainless steel and is controlled by PLC man-machine. It is simple and convenient to operate and easy to clean. Labeling machine equipment experts said that the automatic labeling machine is corrosion-resistant, not easy to rust, and has a long service life. The parts and structures are strong and will not fall for a long time. Advantage 5: High production efficiency Compared with manual labeling, the automatic labeling machine can perform uninterrupted work with less human resources and workshop area, and has higher production efficiency and return efficiency, saving material costs. In addition, the labeling accuracy of the fully automatic labeling machine is also very high, and there is basically no error. Third, the labeling machine is divided into several categories 1: According to different adhesive coating methods, it can be divided into self-adhesive labeling machine, paste labeling machine (adhesive labeling machine, glue labeling machine) and thermal There are several types of melt glue labeling machines. 2: According to the degree of automation, it can be divided into automatic, automatic, semi-automatic and manual labeling machines. 3: According to the realization of different labeling functions, it can be divided into flat labeling machine, side labeling machine and circumferential labeling machine.
