Servo photoelectric positioning color registration curved screen printer:

Working principle

First place the round cosmetic bottle or box on a specific positioning station, and the servo photoelectric positioning system begins to work. The position of the bottle or box is accurately detected by the photoelectric sensor, and then the signal is fed back to the control system. The control system then drives the servo motor to operate and accurately adjust the angle and position of the bottle or box to make it in the accurate initial printing position. Then the screen printing operation is carried out, and the scraper moves on the screen printing plate to transfer the ink through the mesh to the surface of the cosmetic bottle or box. If multi-color printing is required, repeat the above positioning and printing steps, and rely on accurate positioning to ensure accurate color registration.

Main structure and features

• Servo photoelectric positioning system: It is composed of photoelectric sensors, servo motors and supporting control circuits. The photoelectric sensor can keenly capture the position information of the cosmetic bottle or box, and even slight deviations can be detected; the servo motor accurately drives the bottle or box to adjust the angle and position according to the feedback signal to ensure the positioning accuracy before each printing, thereby achieving accurate color registration.

• Screen printing device: including screen printing plate, scraper, ink tank and other components. The screen printing plate carries the pattern and text to be printed, and the scraper is responsible for evenly scraping the ink from the ink tank onto the printing plate and printing the ink through the mesh, which can ensure clear and high-quality printing.

• Operation platform: It is designed with a fixing fixture suitable for round cosmetic bottles and boxes, which can be flexibly adjusted according to products of different sizes, convenient for placing and fixing products, ensuring that the products are in a stable state during the printing process, and helping to improve the printing quality.

Advantages

• Accurate color registration: Thanks to the servo photoelectric positioning system, when performing multi-color printing, the patterns of different colors can be accurately registered, so that the printing effect on the cosmetic bottles or boxes is bright and the transition is natural, the overall appearance is more exquisite and beautiful, and the product grade is improved.

• Wide range of applications: It is specially designed for round cosmetic bottles and boxes, but by replacing different fixing fixtures, it can also adapt to such products of various sizes and specifications to meet the diverse needs of different cosmetics manufacturers.

• Flexible operation: Although it is a semi-automatic device, it is relatively easy to operate. The operator can not only use the automated positioning system to ensure printing accuracy, but also flexibly control the printing rhythm to a certain extent, such as adjusting the printing speed, ink usage and other parameters according to the actual situation, so as to facilitate the response to small batch and diversified production tasks.

• High cost performance: Compared with the fully automatic screen printing machine, its price is relatively more acceptable, and it also has higher printing quality and precision guarantee. It is a more suitable choice for cosmetics companies with limited budget but certain requirements for printing quality.
