Full-servo transmission pressurizing bushing flexible plate printing unit

Abstract

The invention discloses a full-servo transmission pressurizing bushing flexible plate printing unit, which comprises a stander, and a forme roller and a fixed printing roller, which are respectively arranged on two sides of a paper feeding end surface of the stander, wherein a paper inlet end of the forme roller is provided with an anilox roller, the forme roller, the printing roller and the anilox roller are respectively connected with a forme roller motor, a printing roller motor and an anilox roller motor, the stander is provided with a first drive mechanism for controlling the forme roller and the anilox roller to elevate simultaneously, and the anilox roller is connected with a second drive mechanism for controlling the anilox roller to move in the transverse direction. The forme roller, the printing roller and the anilox roller are respectively driven by independent servo motors, so that the linear speed of each roller is enabled to be absolutely synchronous with one another, the pressurizing of the forme roller and the anilox roller are realized by adopting the servo motors, and convenience in operation and high precision can be realized; and the forme roller and the anilox roller adopt bushing-type structures, so that convenience for replacing and disassembling the bushing can be realized. The printing speed can reach 300m / min, the printing precision is high, and the automation degree is high.

Description

【Technical field】 [0001] The invention relates to a printing unit, in particular to a full-servo transmission pressurized sleeve flexographic printing unit, which belongs to the technical field of printing. 【Background technique】 [0002] The printing unit of the existing unit-type flexo printing machine, the anilox roller, the printing plate roller, and the printing roller realize the speed synchronization through gear transmission, and the printing unit of the whole printing machine is powered by a motor, or each The printing unit is powered by a motor, and the screen roller, printing plate, and printing roller share the same motor. During printing, the pressurization method of the screen roll and printing plate is manual operation, manual mechanical pressurization, and the mechanical accuracy and operation accuracy are relatively poor. , and the requirements for the quality of the operators are also high.

AI Technical Summary

Problems solved by technology

[0002] The printing unit of the existing unit-type flexo printing machine, the anilox roller, the printing plate roller, and the printing roller realize the speed synchronization through gear transmission, and the printing unit of the whole printing machine is powered by a motor, or each The printing unit is powered by a motor, and the screen roller, printing plate, and printing roller share the same motor. During printing, the pressurization method of the screen roll and printing plate is manual operation, manual mechanical pressurization, and the mechanical accuracy and operation accuracy are relatively poor. , and the requirements for the quality of the operators are also high

[0003] In addition, the existing printing plates and screen rollers are in the form of an integral type, which needs to be disassembled as a whole when replacing printed products, which is inconvenient to operate

[0004] The printing machine with the above structure, although the cost of the equipment is relatively low, has high requirements on the quality of the operators, and the accuracy, speed and printing effect of the equipment are very poor, which can barely meet the market's requirements for printing products.

Moreover, when replacing printing products, printing plates, anilox rollers and corresponding gears need to be replaced at the same time. At this time, the workload of disassembling these rollers is relatively large, and repeated disassembly and assembly are difficult to guarantee the accuracy of installation.
