A labeling machine is a machine that labels a package or product. The trademarks, main parameters, instructions for use and product introduction on the label are indispensable for modern packaging, and the beautifully designed labels also help to enhance the company's image and promote product sales.
The automatic labeling machine has the following features:
(l) The general structure is complex, the movement speed is fast, and the movement precision is high. In order to meet the performance requirements, there are high requirements for the stiffness requirements and surface quality of the parts.
(2) Packaging machines for food and medicine should be easy to clean, and parts that come into contact with food and medicine should be made of stainless steel or chemically treated non-toxic materials.
(3) The process force during packaging operations is generally small.
(4) Infinitely variable speed devices are generally used to flexibly adjust the speed and adjust the production capacity.
(5) Special types of professional machinery, with many types and limited production.
There are various classification methods for labeling machines. According to the degree of automation, the labeling machine can be divided into semi-automatic labeling machine and automatic labeling machine; according to the running direction of the container, it can be divided into vertical labeling machine and horizontal labeling machine; according to the type of label, it can be divided into slices. Label labeling machine, roll label labeling machine, hot adhesive label labeling machine and pressure sensitive label labeling machine, shrinking cylindrical label labeling machine; according to the movement form of the container can be divided into straight-through labeling machine and Rotary labeling machine; according to the labeling machine structure can be divided into gantry type labeling machine, vacuum drum type labeling machine, multi-standard box drum labeling machine, lever labeling machine, rotary labeling machine; The labeling process features can be divided into a press type labeling machine, a roll type labeling machine, a roll type labeling machine, a brush type labeling machine, and the like.
Currently, there are three main automatic labeling technologies:
(1) "Sucking method" (or "air suction method")
This is the common labeling technology of Zui. When the label paper leaves the conveyor belt, it is distributed onto a vacuum pad that is attached to the end of a mechanical device. When the mechanism is extended until the label comes into contact with the package, it is retracted and the label is attached to the package. This technology reliably achieves correct labeling with high precision. This method is very suitable for top labeling with a certain change in the height of the product package, or for side labeling of difficult-to-handle packages, but it is very suitable. The labeling speed is slower.
(2) "Blowing method" (or "jet method")
Some of the techniques of this technique operate in a similar manner to the above-described suction method by placing the label on a vacuum surface pad until the attachment action begins. However, in this method, the vacuum surface is kept stationary, the label is fixed and positioned on a "vacuum grid", and the "vacuum grid" is a plane having hundreds of small holes thereon, which are used to maintain formation. Air jets. A stream of compressed air is blown from these "air jets" and the pressure is strong, causing the label on the vacuum grid to move and attach it to the packaged item. This is a slightly more complicated technology with high precision and reliability.
(3) "Scratch method" (or "brushing method")
The third method of labeling is called synchronous labeling, and can also be called "scratch method", "brush method" or "contact paste method". At the time of labeling, when the leading edge portion of the label adheres to the package, the product immediately removes the label. In this type of labeling machine, this method can only be successful if the speed of the package is consistent with the speed at which the label is dispensed. This is a technology that needs to maintain continuous operations. In addition, a second device such as a brush or roller is indispensable for the attachment of the label to meet the complete and appropriate requirements.
With the in-depth development of various labeling technologies, the labeling machine is moving in the following development directions:
(l) High productivity, high reliability, high precision, good flexibility and flexibility, focusing on completeness and compatibility;
(2) The degree of automation is constantly improving. The past manual and semi-manual complex operations have been replaced by semi-automatic or automatic labeling machines, and gradually develop in the direction of intelligent control;
(3) Advanced electromechanical technology and new components are integrated into the labeling machine, and the design quality is improved and the manufacturing cycle is shortened by adopting advanced design methods.
As an important part of the packaging production line, the labeling machine directly affects the quality of the packaging. Therefore, efforts should be made to improve the quality of labeling. Comprehensive consideration should be given to the design, manufacture, assembly and commissioning according to the labeling requirements, and the sticker should be satisfied at a lower cost. The functional requirements of the standard machine.
