Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The novel material receiving compression roller device of the unit type gravure printing machine comprises a long shaft 8 which is horizontally arranged, wherein one end of the long shaft 8 is connected with one end of a hollow short shaft 6 through a composite bearing 7, the other end of the short shaft 6 and the other end of the long shaft 8 are respectively connected with a set of compression roller driving assemblies, and one end of the long shaft 8, which is connected with the short shaft 6, is also provided with a fine adjustment assembly; the device further comprises a press roller 9, and two ends of the press roller 9 are respectively connected with one end of the short shaft 6 and the other end of the long shaft 8 through the swing arm 1. The other end of the short shaft 6 and the other end of the long shaft 8 are respectively and fixedly connected with the upper ends of the two swing arms 1.

The structure of the compression roller driving assembly is as follows: the device comprises a cylinder 3, wherein the end part of a piston rod of the cylinder 3 is connected with one end of a cylinder swing arm 4 through a pin shaft;

in the two groups of compression roller driving components, the other ends of two cylinder swing arms 4 are respectively fixedly connected with the other end of the short shaft 6 and the other end of the long shaft 8.
