The following describes a specific structure of the first adjustment mechanism 41:

the first adjusting mechanism 41 includes a plurality of eccentric rotating bases 411 rotatably mounted on the inner side of the machine base 1, a coarse adjusting module 412 disposed on the inner side of the machine base 1 for coarsely adjusting the rotation angle of the eccentric rotating bases 411 and elastically supporting and positioning the eccentric rotating bases 411, a bearing seat 414 eccentrically rotatably mounted on the eccentric rotating bases 411 through an eccentric shaft 413, a fine adjusting module 415 mounted on the eccentric rotating bases 411 for finely adjusting the rotation angle of the bearing seat 414 and supporting and positioning the bearing seat 414, a bearing (not shown) fixed in the bearing seat 414, and a swing arm 417 for simultaneously driving all the eccentric rotating bases 411 to swing against the elastic supporting force provided by the coarse adjusting module 412, wherein the swing arm 417 is in contact with a first driving cam 432 in the power mechanism 43; the end part of the printing roller 105 is fixedly arranged in the bearing in a penetrating way. The swing arm 417 is rotatably mounted at its middle portion to the inside of the housing 1 via a third shaft body.

The number of the eccentric rotating seat 411, the rough adjusting module 412, the bearing seat 414, the fine adjusting module 415 and the bearings in the first adjusting mechanism 41 is four, and the eccentric rotating seat, the rough adjusting module 412, the bearing seat 414, the fine adjusting module 415 and the bearings are installed in a one-to-one matching manner; the number of the swing arms 417 is one.

When the first adjusting mechanism 41 works, the first driving cam 432 in the power mechanism 43 drives the swing arm 417 to swing when rotating, and the swing arm 417 drives all the eccentric rotating seats 411 to overcome the elastic supporting force provided by the rough adjusting module 412 to swing upwards during the swinging process, so as to drive all the forme rollers 105 to be far away from the plate cylinder 101; when the first driving cam 432 in the power mechanism 43 rotates in the opposite direction, the first driving cam 432 no longer jacks up the swing arm 417, the swing arm 417 is no longer forced upward, and the elastic supporting force provided by the coarse adjustment module 412 for the eccentric rotating seat 411 drives the eccentric rotating seat 411 to reset, thereby driving all the forme rollers 105 to approach the plate cylinder 101.

The eccentric rotary base 411 has an arc contact surface 4111; the swing arm 417 has an arc segment 4171 at an upper end thereof, the arc segment 4171 is provided with a plurality of first driving bearings 4172 corresponding to the eccentric rotating base 411 one by one, and an outer circle of the first driving bearings 4172 protrudes out of a side surface of the arc segment 4171 and contacts with the arc contact surface 4111 of the eccentric rotating base 411. When the swing arm 417 swings upward, the swing arm 417 pushes up the arc contact surface 4111 of the eccentric rotating seat 411 through the first driving bearing 4172, and since the two generate rolling friction, the wear is small, and the service life can be prolonged.

Wherein the outer surface of the first drive cam 432 includes a circular arc drive surface 4321 and a flat positioning surface 4322 connected to each other. When the circular arc driving surface 4321 contacts the second driving bearing 4173, the first driving cam 432 pushes up the second driving bearing 4173 to generate an upward force; when the positioning plane 4322 contacts the second driving bearing 4173, the first driving cam 432 no longer jacks up the second driving bearing 4173, and there is no upward force, and at this time, the elastic supporting force provided by the coarse adjustment module 412 for the eccentric rotating base 411 drives the eccentric rotating base 411 to return, so as to drive all the form leaning rollers 105 to approach the form cylinder 101.

When the gap between the plate leaning roller 105 and the plate cylinder 101 needs to be adjusted, the adjustment can be realized by adopting two modes of rough adjustment and fine adjustment. Specifically, when coarse adjustment is required, the rotation angle of the eccentric rotating seat 411 is coarsely adjusted by the fine adjustment module 415, so as to drive the relative angle of the bearing seat 414 installed on the eccentric rotating seat 411, thereby achieving the purpose of coarsely adjusting the gap between the plate roller 105 and the plate cylinder 101; when fine adjustment is required, the fine adjustment module 415 fine adjusts the rotation angle of the bearing seat 414, so as to achieve the purpose of fine adjusting the gap between the form roller 105 and the form cylinder 101.

Specifically, the coarse adjustment module 412 includes a first supporting seat 4121 fixed on the inner side of the machine base 1, a pull rod 4122 slidably passing through the first supporting seat 4121 and hinged to the outer side of the eccentric rotating seat 411, a spring 4123 sleeved on the outer periphery of the pull rod 4122 and providing an elastic supporting force, and a first nut 4124 spirally mounted on the rear end of the pull rod 4122.
