Chapter One Introduction
1.1 Background and development of labeling machine
The labeling machine is a specific mechanical device that attaches a label to a packaging container, and is generally performed at the end of the packaging operation. The label has the function of explaining and decorating the product, and it is convenient for the sales and management of the product. The trademark on the label, the specifications and main parameters of the product, the instructions for use and the product introduction are indispensable components of modern packaging.
There are many types of labeling machines with different functions, but the basic principles are similar. Automatic labeling machine is a device that applies paper or labels to specified packaging containers with adhesive.
The function of the labeling machine: it can complete the various tasks such as flat pasting, single or multi-sided pasting of packaging, cylindrical pasting, partial or full pasting, depression and corner pasting.
The types of labeling machine products are divided into linear labeling machines and rotary labeling machines. Features of labeling machine:
Wide range of application: It can realize single side labeling / corner marking on the side (flat surface) of square bottle / flat bottle (full bottle state), as well as single / double post covering function of round bottle circumferential positioning.
Unique material distribution mechanism ensures reliable and effective material distribution when used on-line with the production line. Unique corner support mechanism ensures that the three sides of the square bottle are labelled flat and not wrinkled. It can be used on a single machine and can be used in conjunction with the production line The development process of the standard machine can be divided into three stages: The first stage is from the late 1980s to 1994.
This stage is mainly to introduce and imitate the incomplete labeling machines that have been eliminated from abroad. At that time, several labeling machine manufacturers were only able to produce labeling machines with two labels (neck and body), one was a 12216 rotary labeler, and the other was a 1546 rotary labeler. These domestic machines can basically meet the requirements. As domestic equipment is far from the imported equipment in terms of function, performance, appearance and labeling quality, it is unlikely to pose any threat to imported equipment.
2. The second phase is from 1995 to 2001.
This stage is the promotion phase of China's labeling machine production. The first is the increase in labeling speed, from 24,000 bottles / hour to 33,900 bottles / hour, and the second is the improvement in labeling functions, from the second label (neck and body label) to the fourth label. Neck, body, back label. Each labeling machine manufacturer is researching the function of adding the labeling and back labeling on the original two-labeling machine, and it is also actively developing the four-labeling machine. 3. The third stage from 2002 to the present.
This stage is the mature stage of China's labeling machine technology and a major turning point in the history of China's labeling machine. In recent years, while domestic labeling machine manufacturers have competed with each other, they have also formed a situation of competing with foreign labeling machine manufacturers. They have improved in the competition, developed in the process of improvement, innovated in development, and strengthened in innovation. Gradually completed a "qualitative" leap. In September 2002, Pinghang independently developed a high-speed rotary labeling machine with a PH40088P (production capacity of 50900 bottles / hour), which was unveiled at the "2002 China International Beer and Beverage Manufacturing Technology and Equipment Exhibition" in Beijing, immediately Caused a sensation in the industry. In 2003, Pinghang PH40-8-8 high-speed rotary labeling machine won 4 national utility model patents. The project passed the scientific and technological achievements appraisal in Jinhua City, Zhejiang Province in August 2004 (so far, it is still the only domestic labeling machine that passed the provincial appraisal). The project won the second prize of 2005 Guangdong Science and Technology Progress Award. It was listed as “National Key Protection Project in 2005 and won the approval of its peers.
The main products of the packaging machine labeling machine are: self-adhesive labeling machine, sleeve labeling machine, round bottle labeling machine, beer labeling machine, semi-automatic labeling machine, automatic labeling machine, automatic labeling machine, labeling machine , Automatic labeling machine. These products can complete various kinds of labeling such as flat surface pasting, single-sided or multi-sided pasting of packages, cylindrical pasting, partial or full cylinder pasting, depression and corner pasting.
Self-adhesive labeling is the most common form of labeling in recent years, and its technology is rapidly improving. For production enterprises, no matter from the labeling production equipment, or from the self-adhesive label and the bottle itself, it will raise higher requirements.
The application and development of stickers in the daily chemical industry are combined with the overall development of the daily chemical industry. Generally speaking, there are two major development trends:
1. First, the demand for daily-use products for self-adhesive labels will maintain rapid growth
On the one hand, the daily chemical industry itself is developing very fast, and the entry of many well-known multinational companies. At the same time, the formation of a large number of large domestic industrial groups also illustrates this. These large companies have large output and high degree of automation, and are not suitable for fast automatic labeling. There will be great demand for adhesive labels. On the other hand, washing products are the main component of the daily chemical industry. Now liquefied washing products have become the industry trend. Many enterprises that originally produced solid washing products have now invested in large-scale liquid washing equipment to produce liquid washing products. This will greatly promote the demand for self-adhesive labels suitable for various bottle bodies.
2. The level of demand for adhesive labels for daily chemical products will be higher, and the materials will be more diverse
on the one hand,
The daily chemical industry itself is becoming more and more advanced in the development of production automation, so the demand for self-adhesive labels will come more from the roll self-adhesive labels suitable for automatic labeling, which requires more rotary printing equipment to cooperate with it. A single sticker suitable for manual labeling will be more limited to large-volume household washing products. On the other hand, daily chemical production enterprises will be more concentrated, the overall level of daily chemical products will be improved, and some well-known brand products will occupy a larger market share. These daily chemical products will need good-quality, high-level stickers to meet the packaging requirements of their products. Film products will get more use, and transparent, label-free ultra-thin film materials will be one of the trends in the next few years.
Domestic and foreign self-adhesive labeling machines have similar working principles. They are made by label peeling, transfer, and rolling, but their control and manufacturing are not the same. Generally, the self-adhesive labeling machine is composed of a labeling mechanism, a rolling mechanism, a conveying mechanism, a transmission mechanism, a frame and a control system. Self-adhesive labeling machine: vertical and horizontal according to the bottle state;
It can be divided into low speed, medium speed, and high speed; round bottles, flat bottles, square bottles, long bottles, etc. according to the characteristics of the container to be affixed (special shaped bottles are less in the pharmaceutical industry); Divided into general labels and transparent labels according to label characteristics
