With the development of science and technology, now entering the era of mechanization, artificial labeling will gradually be eliminated. The labeling machine adopts electromechanical integration technology and advanced photoelectric control devices for food, medicine, daily chemical, chemical and other industries. Specifications of round plastic bottles and glass bottles provide convenience.
Bar code labeling machine is actually a kind of combined mechanical equipment. The main working mechanism is that it can directly print out the required bar code on the label on the conveyor belt. The printing device or printing mechanism is integrated with the labeling unit, and the cylindrical label paper is input through the printing mechanism, then is removed on the conveyor belt, and then the printed label is input into the cylindrical label paper, and then the conveyor belt is removed Finally, the bar code label is completely printed on the product or package.
The labeling machine uses a heat transfer printer, and can also be printed on a thermally activated label paper drum with direct heating. Most models of this type of equipment allow the printing mechanism to achieve the appropriate number of print points per unit length, forming high-definition letters, numbers, and graphics and logos. The printed dots produced by the printing mechanism used on the printing-labelling machine actually appear in shape, and provide particularly good clarity for the lines under magnification when the barcode is printed or checked.
With the improvement of automation level, especially the development of servo motor and stepper motor control technology, and the emergence of production management systems such as MRPII and ERP, the labeling machine is following the following development directions:
(1) The drive of the workpiece or product is changed to a stepping motor or a servo motor to drive the ball screw instead of the traditional cylinder-driven workpiece, which greatly improves the positioning control accuracy of the labeling machine in the process of conveying the workpiece. Improved labeling quality.
(2) The degree of automation has been continuously improved. In the past, manual and semi-manual complex operations have been replaced by semi-automatic or automatic labeling machines, and they have gradually developed toward the direction of intelligent control.
(3) Advanced electromechanical technology and new components are integrated into the labeling machine, and advanced design methods are used to improve product design quality and shorten the manufacturing cycle.
As an important part of the packaging production line, the labeling machine has a direct impact on the quality of packaging. Therefore, efforts should be made to improve the quality of labeling, taking into consideration the trends in the market, and considering the labeling requirements in terms of design, manufacturing, assembly, and debugging. Gradually realize the functional requirements of the labeling machine and promote the long-term development of the industry's health.
