A roller printing machine

Abstract

The invention discloses a roller printing machine, belonging to the technical field of printing and dyeing. The roller printing machine comprises a printing machine base, a lead screw, a feed rod, a driving nut, a lower crossbeam, a lower printing roller, an upper crossbeam, an upper printing roller, a motor and a feed rod fine adjustment mechanism, wherein the rapid adjustment and accurate adjustment of the distance between the lower printing roller and the upper printing roller can be realized by the feed rod fine adjustment mechanism through the screw-thread fit between the lead screw and the driving nut; a driven roller is arranged on the lower crossbeam of the roller printing machine of the embodiment; a pressure sensor and a piezoelectric signal converter are arranged on the upper crossbeam; and the distance between a driving roller and the driver roller can be automatically adjusted according to the thickness of raw materials to be processed and the requirements of printing and dyeing pressure, thereby realizing the self-adaptive adjustment of pressure in the printing and dyeing process, improving the poor printing and dyeing layering of the roller printing machine and avoiding the phenomenon of defective goods such as uneven printing colors.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a roller printing machine. Background technique [0002] The printing machine is a main equipment for textile printing. Its working principle is: through a cylindrical metal net with a pattern (that is, a circular screen), a pure rolling motion is made on the textile to be printed, so that the dye in the circular screen is scraped Under the pressure of the printing device, it is transferred to the fabric through the mesh with a patterned circular screen, thereby completing the printing process of the textile. Rotary screen printing has low net cost and convenient processing, and is currently the most important printing method. However, the accuracy of rotary screen printing is poor, and it is not easy to control printing processes such as special burnt-out and engraved printing. When printing some fabrics with special requirements, rotary screen printing is limited b...

Problems solved by technology

[0005] An embodiment of the present invention provides a roller printing machine, which aims to automatically adjust the distance between the driving roller and the driven roller according to the thickness of the raw material to be processed and the processing pressure, so as to improve the single color of the roller printing machine and the poor sense of printing and dyeing layers. problems, to avoid defective products such as uneven printing colors, and at the same time, it can also improve the heating efficiency of the roller printing machine and reduce the power consumption of the roller printing machine
