Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and in particular relates to an environmentally friendly centralized ink supply device for a printing machine. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). When a printing press is printing, the printed image is first printed from the printing plate onto the rubber cylinder, and then transferred to the paper by the rubber cylinder. According to the number of colors printed in one paper feed, it can be divided into single-color, two-color, four-color and multi-color printing presses. Existing multi-color printing presses mostly use manual inking of different ink fountains, which is inefficient, prone to errors, and affects production.

[0003] For example, the environmentally friendly centralized ink supply device for a printing press with patent number CN202123420167.8 includes a shell, a liquid storage tank is installed at the bottom of the shell, a top cover is covered on the top of the shell, a cylinder is installed on the top cover, the bottom of the cylinder is connected to a movable plate, a connecting rod is installed at the center of the bottom of the movable plate, a piston block is provided at the bottom of the connecting rod, two O-rings are sleeved on the side wall of the piston block, a liquid outlet pipe is installed on the piston block, a corrugated hose is provided at the top of the liquid outlet pipe through a pipe joint, an infusion tube is installed at the top of the corrugated hose through a pipe joint, an installation groove is provided at the bottom of the liquid storage tank, a liquid level sensor is installed inside the installation groove, a liquid replenishment pipe is penetrated through the bottom of the side wall of the liquid storage tank, and an electromagnetic stop valve is installed on the liquid replenishment pipe.

[0004] The above-mentioned prior art solution has the following defects: the ink is contained in the ink barrel and is pressed into the ink outlet tube through the ink pressing cover to realize ink supply. The ink at the bottom of the ink barrel is prone to sedimentation due to being in a static state for a long time, resulting in a higher pigment concentration and darker color at the bottom of the ink barrel, which is not conducive to uniform coloring and printing.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 3As shown, an environmentally friendly centralized ink supply device for a printing press comprises an ink barrel 3, in which a piston plate 7 is provided which slides up and down, the edge of the piston plate 7 is in sealing contact with the inner wall of the ink barrel 3, and preferably an annular sealing ring can be provided, the bottom of the ink barrel 3 is closed, specifically an end plate 4 can be provided, a stirring disk 15 is provided at the bottom of the ink barrel 3, and the stirring disk 15 is rotatably connected to the middle part of the bottom surface of the ink barrel 3, and the rotatable connection is that a column is provided on the end plate 4, and a through hole matching the column is provided on the stirring disk 15, and a plurality of stirring rods 16 are provided on the circumference of the edge of the stirring disk 15, and one end of the stirring rod 16 is fixed on the stirring disk 15, and a groove 17 matching the shape of the stirring disk 15 and the stirring rod 16 is provided on the side surface of the piston plate 7 facing the stirring disk 15, and the stirring A rotating shaft 9 is provided in the middle of the disk 15, one end of the rotating shaft 9 is fixed on the stirring disk 15, and the other end of the rotating shaft 9 passes through the middle of the piston plate 7. The rotating shaft 9 and the middle of the piston plate 7 can be sealed to a certain extent, for example, a rubber sealing ring is provided on the inner wall of the middle hole of the piston plate 7. Of course, no sealing is performed. Although pressure leakage may occur to a certain extent, the normal discharge of ink in the device is not affected. The rotating shaft 9 is rotatably connected to the piston plate 7, and the piston plate 7 can slide up and down on the rotating shaft 9. A mounting frame 2 is provided on the outside of the ink barrel 3, and one end of the rotating shaft 9 located outside the ink barrel 3 is rotatably connected to the mounting frame 2, and a rotating motor 8 is provided thereon, and the rotating motor 8 is fixed on the mounting frame 2, and its output end is fixed to the end of the rotating shaft 9.

[0027] The principle of stirring the ink in the ink barrel 3 in the above technical solution is:

[0028] The rotating motor 8 drives the rotating shaft 9 to rotate, and the stirring plate 15 and the stirring rod 16 will rotate to stir the ink therein to prevent it from agglomerating or forming particles and to prevent precipitation. At the same time, during the downward movement of the piston plate 7, the space in the ink barrel 3 will be compressed, thereby increasing the pressure and causing the ink to be discharged from the ink outlet pipe 5. When the piston plate 7 moves down to the bottom of the ink barrel 3, the stirring rod 16 and the stirring plate 15 will enter the groove 17 provided on the piston plate 7 (at this time, the rotating motor 8 stops rotating and returns to the initial position), and then the piston plate 7 can contact the bottom surface of the ink barrel 3, and then all (most of) the ink in the ink barrel 3 can be discharged, so that before the next addition of ink, there is less residual ink in the ink barrel 3, thereby avoiding the mutual influence between the added ink and the residual ink (changing the ink color, or the preparation ratio of the ink is different, if there is too much residual, it will cause the residual ink and the newly injected ink to influence each other).

[0029] In an practicable manner, an ink outlet pipe 5 is provided on the lower surface of the ink barrel 3 , and a first control valve 6 is provided on the ink outlet pipe 5 . The first control valve 6 is a common stop valve.

[0030] In an operative manner, the mounting frame 2 is symmetrically provided with telescopic elements 10, the telescopic elements 10 are fixed to the mounting frame 2, and the output end of the telescopic elements 10 is fixed to the piston plate 7. Preferably, the telescopic elements 10 are linear motors.

[0031] In one feasible manner, a mounting plate 11 is further provided on the mounting frame 2, a conical funnel 12 is provided on the mounting plate 11, an ink injection hole 18 is provided on the piston plate 7, an ink injection tube 13 is provided between the conical funnel 12 and the ink injection hole 18, one end of the ink injection tube 13 is connected to the ink injection hole 18 respectively at one end of the conical funnel 12, a second control valve 14 is provided on the ink injection tube 13, and the second control valve 14 is a common stop valve. The advantage of providing the conical funnel 12 at the same time is that ink can be injected into the ink barrel 3 through this, avoiding the problem of ink spilling all over the ground when injecting, which can play an environmental protection role to a certain extent.

[0032] In an practicable manner, the ink injection tube 13 is a hose, specifically, the ink injection tube 13 is a corrugated tube.

[0033] In one practicable manner, a mounting base 1 is provided at the lower end of the mounting frame 2, and the mounting frame 2 is fixed on the mounting base 1. The mounting base 1 is provided with a plurality of anchor bolts and can be fixed on the ground to ensure stability during operation.

[0034] It should be noted that the remaining components of the ink supply device, such as the heating component and the air intake valve, are prior art and will not be described in detail herein.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
