The ink amount adjusting device 75 includes a horizontal displacement adjusting mechanism 751, a displacement adjusting seat 752, a slide adjusting seat 753, and a slide 754, the displacement adjusting seat 752 being mounted on the horizontal displacement adjusting mechanism 751 and being capable of adjusting horizontal displacement by the horizontal displacement adjusting mechanism 751; one end of the sliding adjusting seat 753 is rotatably connected with the displacement adjusting seat 752, and the other end of the sliding adjusting seat 753 is rotatably connected with a connecting rod 741 of the connecting rod driving mechanism 74; the sliding body 754 is placed in the horizontal sliding groove 701 of the sliding adjusting seat 753, the other end of the swinging connecting block 76 is connected with the sliding body 754 through a shaft body, and the swinging amplitude of the swinging connecting block 76 is adjusted by adjusting the position of the sliding body 754 in the horizontal sliding groove 701, so that the rotating speed of the ink fountain roller 72 is adjusted, and the ink quantity is adjusted. Specifically, when the ink amount adjusting device 75 is operated, the horizontal displacement adjusting mechanism 751 drives the displacement adjusting seat 752 to horizontally move, so that the sliding body 754 is driven to slide in the horizontal sliding groove 701 of the sliding adjusting seat 753, and further, the position of the sliding body 754 in the horizontal sliding groove 701 is adjusted, and since the other end of the sliding adjusting seat 753 is rotatably connected with the connecting rod 741 of the connecting rod driving mechanism 74, the other end of the swinging connecting block 76 is connected with the sliding body 754 through the shaft body, so that the contact position of the other end of the swinging connecting block 76 with the sliding adjusting seat 753 is changed, so that when the connecting rod 741 of the connecting rod driving mechanism 74 drives the sliding adjusting seat 753 to vertically swing, the swinging amplitude of the swinging connecting block 76 is changed, and at this time, the rotating speed of the ink fountain roller 72 is also changed, thereby realizing the purpose of adjusting the ink amount between the ink fountain and the ink fountain roller. More specifically, since the slider 754 slides in the horizontal sliding groove 701, the sliding adjustment seat 753 corresponds to an extended structure of the swing link 76 in the longitudinal direction, and when the slider 754 moves in the horizontal sliding groove 701 in the direction of the link 741, the length of the swing link 76 increases, that is, the swing arm increases, and at this time, since the amplitude of the driving of the link 741 is fixed, the amplitude of the swing link 76 swinging up and down becomes small, the rotation speed of the ink fountain roller 72 becomes slow, and the ink supply amount is reduced; when the slider 754 moves in the opposite direction of the link 741 in the horizontal sliding groove 701, the length of the swing link 76 is shortened, that is, the swing arm is shortened, and at this time, since the amplitude of the driving of the link 741 is fixed, the amplitude of the up-and-down swing of the swing link 76 is increased, the rotation speed of the ink fountain roller 72 is increased, and the ink supply amount is increased; the operation is completed by mechanical automation operation, the labor intensity is low, the time and the labor are saved, the operation is convenient, and the ink supply quantity can be increased or reduced to meet different use requirements.

The specific structure of the first regulating mechanism 41 will be described below: the first adjusting mechanism 41 includes a plurality of eccentric rotating bases 411 rotatably mounted on the inner side of the base 1, a coarse adjusting module 412 disposed on the inner side of the base 1 for coarse adjusting the rotation angle of the eccentric rotating bases 411 and forming an elastic supporting and positioning for the eccentric rotating bases 411, a bearing block 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 fine adjusting the rotation angle of the bearing block 414 and forming a supporting and positioning for the bearing block 414, a bearing (not shown) fixed in the bearing block 414, and a swinging 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 swinging arm 417 contacts with the first driving cam 432 in the power mechanism 43; the end of the plate leaning roller 105 is penetrated and fixed in the bearing.
