Embodiment Construction

[0007] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0008] figure 1 A drive mechanism according to an embodiment of the invention is schematically shown.

[0009] As shown in the figure, the direct drive mechanism of the printing unit used in the printing unit of the present invention includes: a motor 10 and a printing unit.

[0010] In this embodiment of the present invention, the printing unit is distributed with an impression cylinder 1 , a blanket cylinder 2 and a plate cylinder 3 sequentially from bottom to top. Wherein, the impression cylinder 1 and the blanket cylinder 2, and the blanket cylinder 2 and the printing plate cylinder 3 are tangent, and both ends of the impression cylinder 1, the blanket cylinder 2 and the printing plate cylinder 3 are fixed on the frame of the printing unit through cylinder bearings.

[0011] The motor 10 is connected with the impression cylinder...

Abstract

The invention discloses a drive mechanism, which comprises a motor, an impression cylinder, a blanket cylinder and a plate cylinder, wherein the impression cylinder, the blanket cylinder and the plate cylinder are distributed in a printing unit from bottom to top; and each two cylinders are tangent to each other. The drive mechanism adopts the independent motor to drive the cylinders of each printing unit, so that a box structure of a transmission face is simplified, the difficulty in design, processing and assembly is reduced, and the accuracy of printing is ensured. Meanwhile, the servo motor is adopted to drive the cylinders, the circumferential overprinting adjustment of the printing unit is realized.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a driving mechanism. Background technique [0002] The driving method of the traditional printing unit is: a motor is used to drive the printing units in all printing units, and the printing units are driven by gears. The structure of the printing unit using this driving method is very complicated. At the same time, this structure has very high requirements on the precision and assembly process of the transmission device. It requires transmission shafts of different sizes, layers of transmission wheels, high-precision machining parts, and strict assembly processes to ensure its overall quality. Moreover, a motor is used to drive a printing unit, the mechanical mechanism is very complicated, and the noise generated when the machine is running is large. Contents of the invention [0003] The purpose of the present invention is to provide a driving mechanism that simplifies th...
