When the printing machine is used for a long time, the ink in the ink fountain is easy to crust. The ink skinning refers to the formation of gel caused by the oxidation of vegetable oil or the volatilization of organic solvents, which leads to polymerization of the ink system and the like, when the surface layer of the printing ink is in contact with air for a long time in the process of storage or printing. After the ink crusts, the viscosity increases, resulting in a reduction in print quality. Therefore, the prior ink fountain device of the printing machine has the problems of easy skinning and unsatisfactory printing quality.

In order to achieve the purpose, the invention adopts the following technical scheme: a printing machine ink fountain comprises a cylinder body, wherein a stirring shaft is arranged in the cylinder body, a Z-shaped upright post and a rack in sliding connection are arranged at the top of the cylinder body, one end of the Z-shaped upright post is rotatably connected to the cylinder body, a rectangular frame is fixedly connected to the rack, the other end of the Z-shaped upright post is slidably connected in the rectangular frame, first gears meshed with the rack are arranged on two sides of the rectangular frame, first rotating shafts are fixedly connected to the two first gears, the first rotating shafts are rotatably connected to the cylinder body, one ends of the two first rotating shafts, far away from the first gears, extend into the cylinder body and are fixedly connected with abutting blocks, and inclined planes with the same direction are arranged on the; the tank body is arranged in the tank body, the tank body is movably connected to the top wall of the tank body, an accommodating cavity is formed between the tank body and the top wall of the tank body, the supporting blocks are located in the accommodating cavity, one of the supporting blocks is abutted to the inclined surface of the tank body, the other supporting block is abutted to the inclined surface of the tank body and is deviated from the side wall of the tank body, the bottom end of the inclined surface deviated from the side wall of the tank body is abutted to the side wall of the tank body, a sliding rail is arranged at the bottom.

The principle and the advantages of the scheme are as follows: at the beginning, because the inclined plane of a piece deviates from the lateral wall of cell body for the bottom of inclined plane supports under the cell body, and another inclined plane of supporting the piece supports on the lateral wall of cell body, consequently supports the inclined plane on the lateral wall of cell body and does not support under the cell body, makes the both ends atress of cell body uneven and makes the cell body take place the slope from this, and the slide rail of cell body bottom is followed and is the tilt state, and the (mixing) shaft is located the low side of slide rail under the action of gravity.

When the Z-shaped upright post rotates under the action of external power, one end of the Z-shaped upright post, which is connected in the rectangular frame in a sliding manner, rotates around the other end due to the eccentric position, and slides in the rectangular frame continuously to push the rectangular frame to move transversely in a reciprocating manner, so that the rectangular frame drives the rack to move transversely in a reciprocating manner. When the rack moves forwards, the rack pushes the two first gears to rotate forwards together, the two first gears drive the first rotating shafts which are connected with each other to rotate, and the first rotating shafts drive the supporting blocks which are correspondingly connected in the cylinder body to rotate forwards.

In the process of forward rotation of the two abutting blocks, the inclined plane of one of the abutting blocks rotates from a state of abutting against the side wall of the tank body to a state of deviating from the inclined plane and the side wall of the tank body, so that the lower end of the inclined plane abuts against the side wall of the tank body and pushes down the end part of the tank body which is opposite to the inclined plane; and the inclined plane of the other abutting block rotates from a state of deviating from the side wall of the groove body to a state of abutting against the side wall of the groove body, so that the end part of the opposite groove body is released by the bottom end of the inclined plane, and the groove body inclines to the other side. When the rack moves reversely, the rack pushes the two first gears to rotate reversely, the first gears drive the two abutting blocks to rotate reversely through the first rotating shafts, so that the two abutting blocks are restored to the initial state, and the groove body is inclined towards the original direction.

In the process of continuous reciprocating inclination at two ends of the tank body, the slide rail at the bottom of the tank body is also continuously inclined, so that the stirring shaft continuously reciprocates in the slide rail under the action of gravity to stir ink in the ink fountain back and forth, the ink in the ink fountain continuously moves, the ink surface layer is difficult to stand and contacts with air for a long time to cause skinning, the viscosity of the ink can be well maintained, and the printing quality is improved.
