Introduction Of Printing Machine Of Flat Screen Printer Factory


In recent years, there are many types of Flat Screen Printer Factory that are being used normally by flat screen printing machines.

 In recent years, there are many types of Flat Screen Printer Factory that are being used normally by flat screen printing machines. The more common ones are: flat screen printing machines, rotary screen printing machines, thermal transfer printing machines, digital printing machines, etc.

Flat screen printing machine
It is the most suitable for the printing of clothing rolls in a whole roll. It is driven by rubber guide belts to reach the predetermined position of the printing net. The flat screen printing frame falls down and adheres to the cloth. The printing scraper installed in the frame drives the printing paste to hang the printing back and forth. The printing paste placed in the flat mesh is printed on the cloth through the hollow mesh. The pattern of the first color is printed, the screen frame is lifted, and the guide belt sends the cloth to the bottom of the next frame. It is scheduled to stop, and the printing and dyeing of the second color pattern is started, and it repeats until multiple colors (more than 10 can be printed) (More than three colors) After the registration is printed in sequence, you can work continuously without interruption. After the printing of each bundle of cloth is completed, it reaches the next drying device for continuous automatic drying, and then chooses whether to steam, wash, and shape according to different requirements.

 

Rotary screen printing machine
Rotary screen printing machine, also known as horizontal rotary screen printing machine, Open Type Rotary Screen Printing Machine, its printing net is cylindrical, cloth conveying method is similar to flat screen printing machine. A printing scraper is installed in the round net, and the knife holder is fixed on both sides. The printing paste passes through the feed pump and is sprayed into the round net through the scraper frame. After the scraping of the scraper, the paste penetrates into the fabric through the mesh. The finishing process after scraping is similar to the flat screen printing machine. Because its printing net is round, this kind of printing method can make up for the defect that the flat screen printing machine is not good at printing longitudinal straight pattern seams.

 

Thermal transfer printing machine
It belongs to the category of transfer printing. It can be used for thermal transfer printing on fabrics, clothing, or garments, or thermal transfer printing for socks or other chemical fiber fabrics. In terms of working methods, it is quite different from flat screen printing and round screen printing. Before transfer printing on fabrics, clothing, and ready-to-wear, first use sublimation dye ink to print on specific printing paper with printing machinery to become transfer printing paper, and then put the pattern on the printing paper closely to the fabric and enter the transfer printing machine. Heating and pressurizing, the sublimation dye ink on the transfer printing paper is transferred to the fabric after vaporization. This type of printing method has an aspect that is less troublesome than flat screen printing or rotary screen printing, that is, it does not need to be steamed, washed, dried, and shaped after printing. Regrettably: Wool and cotton fabrics cannot be printed temporarily.

 

Garment printing machine
Apparel printing machine belongs to screen printing. It can be used for screen printing of clothes and screen printing of cutting pieces. From the analysis of printing machine structure, it can be divided into rotary printing machine and elliptical printing machine.

(1) Carousel printing machine: printing small area printing water paste is a good choice, and light color cloth printing can also be used to print hot-fixed dots. However, due to the limitation of its work station, printing needs to be printed with one-color drying and one-color glue and thermosetting ink that needs to be white on dark cloth, remove the drying position, cooling position, and loading position after printing. At the receiving position, there are few working positions left for printing. Due to the lack of printing positions of this model, it is impossible to print multi-color glue. Moreover, after a printing machine is repurchased, the printing position cannot be increased. Such outstanding shortcomings result in fewer and fewer buyers.
  
(2) Elliptical printing machine: The printing operation method is basically the same as that of the rotary machine. However, due to the characteristics of the elliptical machine itself, the number of printing platen positions can be expanded infinitely, which overcomes many shortcomings of the rotary machine and thus solves the rotary machine The shortcomings of glue paste cannot be printed. Whether it is a disc printing machine or an elliptical printing machine, there is a common feature: the printing table is individually block-shaped, and it is not as continuous as tens of meters in length like the artificial silk screen running table. You can print the garment on the printing workbench, or you can print garment pieces (cannot print the entire roll of cloth), and you can not print pieces with an extra large area, because both models are supported by a head platen. If the platen is too large, it will lose its balance. Running speed and stability will be affected. In the production practice, the large-scale full-bottom printing is most needed to complete the machine, because the large-scale full-bottom printing is unevenly printed by manual scraping, the printing is not good, or even not printed. For small-area partial printing, manual printing on the treadmill is fast, labor-saving and power-saving (the long platen can be naturally dry), unless you can't find a scraper, then consider buying a small-area printing machine, this is Why do people who buy elliptical machines blindly increase the platen?
  

Digital printing machine
The working principle of digital printing is basically the same as that of inkjet printers. In short, digital printing is to input the pattern to the computer through digital form, edit and process it through the computer printing color separation and drafting system (CAD), and then the computer controls the micro piezoelectric The inkjet nozzle directly sprays the special dyeing liquid onto the textile to form the desired pattern, and then performs different post-processing according to the organizational composition of different fabrics, such as drying and fixing. The advantages of this type of printing method: because no water resources are needed in the printing process, it will not cause pollution to the environment.
