Control system and method for rotary screen printing

Abstract

The invention provides a control system and method for rotary screen printing. The control system at least comprises a plurality of servo drivers, a motor encoder, an acquisition module and a motion control module, the motor encoder is used for sensing relevant information of a main motor shaft driving a conduction band in rotary screen printing, and the acquisition module is used for acquiring rotary screen printing information and control instructions. When the control instructions are rotary screen printing starting signals, the motion control module simulates running of a spindle based on the rotary screen printing information and the relevant information from the main motor shaft of the motor encoder, so that running of electronic gears is simulated, control information is outputted to the servo drivers based on running of the electronic gears, and respective rotary screen rollers are respectively driven. In addition, the motion control module can adjust running of the electronic gears based on rectifying information, and can simulate running of the electronic gears based on the rotary screen printing information when the main motor shaft stops, so that rotary screen printing is realized without the shaft and gear transmission.

Description

technical field [0001] The invention relates to the field of rotary screen printing, in particular to a control system and method for rotary screen printing. Background technique [0002] Textile products used in people's daily life, such as bed sheets, curtains, quilt covers, etc., are usually made by rotary screen printing. [0003] Existing rotary screen printing machines usually have eight colors, twelve colors, sixteen colors, and twenty-four colors. When using twelve colors to produce textiles, the technical difficulties lie in the synchronous control of the 12-axis rotary screen, the color registration correction during the operation of the rotary screen, and the single movement of the guide belt. When the fabric is brought to the guide belt by the cloth feeding roller, the guide belt will guide the cloth forward, and at the same time, the 12-axis printing nickel roller will overprint the pattern on the cloth, and then enter the oven after forming the pattern.

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the process of the rotary screen printing machine is complicated, and the existing rotary screen printing machines all adopt the mechanical spindle transmission mode. This kind of mechanical transmission has the following deficiencies:

[0005] (1) A large number of complex and expensive gear transmissions are required, and the rotary screen cannot be operated alone;

[0006] (2) The viscosity coefficient of the mechanical transmission system is very small, and resonance is prone to occur

[0008] (4) The power of a single motor is limited, which limits the driving power shared by each axis, resulting in the limitation of the load of each axis;

[0009] (5) The wear of the mechanical transmission shaft will easily cause a complex state where multiple machine parts and various faults are intertwined, which is not conducive to the separation and elimination of faults
