Description

Technical Field

[0001] The present application relates to the field of printing presses, and in particular to an ink tank structure of a printing press. Background Art

[0002] Printing presses are devices used to print text, images or patterns onto substrates such as paper, textiles, plastic films, etc. They are widely used in publishing, packaging, advertising and other industries. Different types of printing presses can be divided into lithographic printing presses, offset printing presses, gravure printing presses, screen printing presses, etc. according to their printing methods and uses. These machines can print in an efficient and precise manner and are one of the indispensable and important equipment in modern industrial production.

[0003] The ink tank of a printing press is a component used to store and provide ink on a printing press. The ink tank is usually composed of one or more ink storage tanks. During the printing process, the ink is transported from the ink storage tank to the surface of the printing plate or printing material through the ink roller. However, the ink in the ink storage tank will be consumed after a certain period of use, and the ink accumulation height in the ink storage tank will decrease, which will lead to a decrease in the amount of ink adhered to the ink roller. This may cause unclear printing when the ink roller is in use. However, the internal volume of the ink storage tank is generally fixed, and more ink needs to be added to keep the outer surface of the ink roller fully saturated, resulting in a high demand for ink, which will cause a certain amount of waste in the overall use of ink and also affect the efficiency of the use of the ink roller.

[0004] In view of the above-mentioned related technologies, the inventor believes that the ink in the ink storage tank has the defect of not being convenient for fully soaking the ink roller. Therefore, an ink tank structure of a printing press is proposed to solve the above-mentioned problem. Utility Model Content

[0005] In order to solve the problem that the ink in the ink storage tank is not convenient for fully soaking the ink roller, the present application provides an ink tank structure of a printing press.

[0008] Preferably, the sliding mechanism includes a driven gear, which is rotatably mounted at the middle of the bottom end of the movable rotating plate, a cylinder is mounted on one side of the bottom end of the ink box, and an active rack is mounted at the output end of one side of the cylinder.

[0009] Preferably, support plates are symmetrically welded to both side edges of the ink box, and support rods are symmetrically welded between the two support plates on the same side through a connecting plate.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an ink tank structure of a printing press. Figure 1-3 , an ink tank structure of a printing press, comprising an ink box 1, an ink storage tank 2 is provided in the middle of the top of the ink box 1, an ink roller 3 is rotatably installed in the middle of one side of the inner wall of the ink storage tank 2, ink baffles 4 are movably installed on the edges of the front and rear ends of the inner wall of the ink storage tank 2, and a sealing gasket 5 is welded on one side of the outer surface of the ink baffle 4, fixed long grooves 6 are provided through the top of both sides of the ink box 1, and connecting plates 7 are welded on both sides of the ink baffle 4 through the fixed long grooves 6 to extend to the outside of the ink box 1, and the bottom ends of the connecting plates 7 on both sides of the single ink baffle 4 are placed under the ink box 1 and are welded with fixed plates 10, a movable rotating plate 11 is rotatably installed in the middle of the bottom end of the ink box 1, and a connecting rotating plate 12 is hinged between the bottom edge of the movable rotating plate 11 and the middle of the bottom end of the fixed plate 10, and a sliding mechanism is also provided at the bottom of the ink box 1 for controlling the movable rotating plate 11 to adjust the angle.

[0020] Ink is poured into the ink storage tank 2, and the ink shielding plate 4 is placed at the edge of the ink storage tank 2, so that the ink roller 3 is dipped in ink and transported to the printing material, the movable rotating plate 11 is rotated to drive the connecting rotating plate 12 to rotate, and then the fixed plate 10 is pulled to move, and the distance between the two fixed plates 10 is adjusted, so that the fixed plate 10 drives the connecting plate 7 to move, and drives the ink shielding plate 4 to move along the inside of the ink storage tank 2, so that the ink shielding plate 4 cooperates with the sealing gasket 5 to push the ink inside the ink storage tank 2 to accumulate in the middle position, thereby increasing the overall liquid level height of the ink inside the ink storage tank 2, which reflects the effect of the ink shielding plate 4 on gathering the ink in the ink storage tank 2.

[0021] Reference Figure 2 The sliding mechanism includes a driven gear 13, which is rotatably mounted at the middle of the bottom end of the movable rotating plate 11. A cylinder 14 is mounted on one side of the bottom end of the ink box 1, and a driving rack 15 is mounted at the output end of one side of the cylinder 14. One end of the driving rack 15 moves close to the outer surface of the driven gear 13, and the driven gear 13 and the driving rack 15 are meshed with each other.

[0022] By starting the cylinder 14 to drive the driven gear 13 to move, the active rack 15 moves through the outer surface of the driven gear 13, and then the active rack 15 drives the driven gear 13 and the movable rotating plate 11 to rotate, reflecting the overall angle adjustment effect of the movable rotating plate 11.

[0023] Reference Figure 2 and Figure 3 Support plates 8 are symmetrically welded on both side edges of the ink box 1, and support rods 9 are symmetrically welded between the two support plates 8 on the same side through the connecting plate 7. A through hole is symmetrically opened in the middle of one side of the connecting plate 7. The outer diameter of the support rod 9 is smaller than the inner diameter of the through hole. One side of the outer surface of the support rod 9 is located inside the through hole, and the support rod 9 and the through hole are coupled to each other.

[0024] By making the movable fixed plate 10 drive the connecting plate 7 to move along the outer surface of the support rod 9, the support rod 9 supports the movable connecting plate 7, thereby keeping the connecting plate 7 stable and movable, which reflects the supporting effect of the support rod 9 on the connecting plate 7.

[0025] The implementation principle of the ink tank structure of a printing machine in the embodiment of the present application is as follows: by pouring ink into the ink storage tank 2 and placing the ink baffle 4 at the edge of the ink storage tank 2, the ink roller 3 is dipped in ink and transported to the substrate; when the ink height in the ink storage tank 2 is reduced, the cylinder 14 is started to drive the driven gear 13 to move, and the input end of the power supply of the cylinder 14 is electrically connected to the output end of the external power supply, so that the active rack 15 in the activity drives the driven gear 13 and the movable rotating plate 11 to rotate, so that the movable rotating plate 11 moves and drives the connecting rotating plate 12 to rotate synchronously, and then pulls the fixed plate 10 to move, and adjusts the distance between the two fixed plates 10, so that the fixed plate 10 drives the connecting plate 7 along the outer side of the support rod 9. The surface is movable, so that the support rod 9 supports the movable connecting plate 7 and drives the ink baffle plate 4 to move along the inside of the ink storage tank 2, so that the fixed long groove 6 guides and supports the movable ink baffle plate 4, thereby keeping the ink baffle plate 4 in a stable movable state inside the ink storage tank 2, and the ink baffle plate 4 pushes the ink inside the ink storage tank 2 to accumulate in the middle position, thereby increasing the overall liquid level height of the ink inside the ink storage tank 2; compared with the prior art, this solution has the effect of facilitating the ink to be fully coated on the outer surface of the ink roller 3, thereby improving the overall use efficiency of the ink roller 3, solving the problem that the ink in the ink storage tank 2 affects the printing effect as the use height decreases, and improving the overall use efficiency of the ink in the ink storage tank 2.
