Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an ink tank for printing. Background Art

[0002] A printing press is a device that prints text and images on the surface of a carrier. It can be divided into letterpress, lithographic, gravure and screen printing presses according to the form of the printing plate. Among them, products produced by gravure printing machines have the advantages of thick ink layer, rich layers, strong three-dimensional effect and good printing quality. They are widely used in printing exquisite color pictures, trademarks, decorations, securities and color newspapers. They are mainly composed of paper feeding mechanism, inking mechanism, printing mechanism, drying mechanism and paper collection mechanism. The ink tank is the feeding mechanism for the ink roller during printing. Usually, the bottom of the ink roller is immersed in the ink pool of the ink tank. As the ink roller rotates, the ink is evenly adhered to print.

[0003] When the existing ink tank is in use, the ink roller continuously adheres ink for printing, causing the ink amount in the ink pool to continuously decrease. In order to avoid uneven adhesion of ink by the ink roller, manual ink replenishment is required at regular intervals, which is not conducive to production. Utility Model Content

[0004] The technical solution of the present utility model addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present utility model is to provide an ink tank for printing to solve the problem proposed in the above background technology that the amount of ink in the ink pool continues to decrease due to the continuous adhesion of ink by the ink roller for printing. In order to avoid uneven adhesion of ink by the ink roller, manual and regular ink replenishment is required, which is not conducive to production.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printing ink tank, comprising a tank body, two groups of elastic telescopic rods symmetrically arranged on the bottom of the tank body, the telescopic ends of the elastic telescopic rods are connected to an ink tray, and limiting structures are symmetrically and evenly spaced on the upper end of the inner wall of the ink tray, two groups of side panels are symmetrically arranged inside the ink tray, and the side panels are located on the inner side of the limiting structure, the side walls of the tank body are provided with support plates, the top of the support plates is provided with an auxiliary ink tank, the lower outer wall of the auxiliary ink tank is provided with a pipe, the bottom of the pipe is connected to the middle of the side wall of the ink tray with a hose, and the inside of the pipe is provided with an opening and closing mechanism.

[0006] Preferably, symmetrical notches are provided on both sides of the trough body.

[0007] Preferably, the limiting structure includes two groups of clips fitted on the outer wall of the side panel.

[0008] Preferably, the side plate fits with the inner wall of the ink tray, and a sealing strip is provided on the edge of the ink tray.

[0009] Preferably, the opening and closing mechanism includes a rotating shaft rotatably connected to the pipeline, one end of the rotating shaft extends out of the outer wall of the pipeline and is connected to a gear, the outer wall of the rotating shaft is located inside the pipeline and a valve plate is provided, and the top of the ink tray is provided with a rack meshing with the gear.

[0010] Preferably, the outer wall of the valve plate is provided with a sealing ring that fits against the inner wall of the pipeline.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The utility model can draw out the side plate from the card strip according to the length of the ink roller and insert it between the two sets of card strips near the two ends of the ink roller. Since the side plate fits closely with the card strip and there are sealing strips on the edge of the side plate, the ink tray after the side plate is inserted can form different sealing spaces, thereby adapting to the length of the ink roller and reducing waste.

[0013] (2) The utility model is used as the ink roller rotates to adhere the ink, the ink surface in the ink tray gradually decreases, and the weight of the ink tray decreases accordingly. Under the action of the elastic telescopic rod, the ink tray moves upward by a corresponding distance. At this time, the ink tray drives the rack on the top to move upward, and the rack drives the gear to rotate. The gear drives the shaft to rotate a certain angle, and the shaft drives the valve plate to rotate a certain angle in the pipeline to make the pipeline conductive. The ink in the auxiliary ink tank enters the ink tray through the pipeline and the hose until the weight of the ink tray compresses the elastic telescopic rod again to reset to the initial compression state. The valve plate rotates and resets to close the pipeline, so that the ink surface height in the ink tray can be balanced, avoiding uneven adhesion of the ink roller to the ink.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an ink tank for printing, comprising a tank body 1, two groups of elastic telescopic rods 2 are symmetrically arranged at the bottom of the tank body 1, the telescopic ends of the elastic telescopic rods 2 are connected to the ink tray 3, and the upper end of the inner wall of the ink tray 3 is symmetrically and evenly spaced with limiting structures, and two groups of side panels 5 are symmetrically arranged inside the ink tray 3, and the side panels 5 are located on the inner side of the limiting structure, the side wall of the tank body 1 is provided with a support plate 6, and the top of the support plate 6 is provided with an auxiliary ink tank 7, and the outer wall of the lower end of the auxiliary ink tank 7 is provided with a pipe 8, and a hose 9 is connected to the bottom of the pipe 8 and the middle of the side wall of the ink tray 3, and an opening and closing mechanism is provided inside the pipe 8.

[0021] Symmetrical notches are provided on both sides of the tank body 1 .

[0022] The limiting structure includes two groups of clips 4 that are fitted on the outer wall of the side panel 5 .

[0023] The side plate 5 fits with the inner wall of the ink tray 3 , and a sealing strip is provided on the edge of the ink tray 3 .

[0024] The opening and closing mechanism includes a rotating shaft 10 rotatably connected to the pipe 8. One end of the rotating shaft 10 extends out of the outer wall of the pipe 8 and is connected to a gear 11. The outer wall of the rotating shaft 10 is located inside the pipe 8 and is provided with a valve plate 12. The top of the ink tray 3 is provided with a rack 13 that meshes with the gear 11.

[0025] The outer wall of the valve plate 12 is provided with a sealing ring that fits against the inner wall of the pipe 8 .

[0026] Working principle: When using the printing ink tank, first, according to the length of the ink roller, pull the side plate 5 out of the clamping strip 4 and insert it between the two sets of clamping strips 4 near the two ends of the ink roller. Because the side plate 5 fits closely with the clamping strip and there are sealing strips on the edge of the side plate 5, the ink tray 3 after the side plate 5 is inserted can form different sealed spaces, thereby adapting to the length of the ink roller and reducing waste.

[0027] Then, the notches on the side wall of the tank body 1 are used to prevent the shaft ends of the ink roller from moving. Then, a proper amount of ink is added to the ink tray 3. The ink surface is above the bottom surface of the ink roller. At this time, the weight of the ink tray 3 compresses the elastic telescopic rod 2, and then the ink is replenished into the auxiliary ink tank 7.

[0028] Finally, as the ink roller rotates to adhere the ink for use, the ink level in the ink tray 3 gradually decreases, and at the same time, the weight of the ink tray 3 decreases accordingly. Under the action of the elastic telescopic rod 2, the ink tray 3 moves upward a corresponding distance. At this time, the ink tray 3 drives the top rack 13 to move upward, and the rack 13 drives the gear 11 to rotate. The gear 11 drives the rotating shaft 10 to rotate a certain angle, and the rotating shaft 10 drives the valve plate 12 to rotate a certain angle in the pipe 8 to make the pipe 8 conductive. The ink in the auxiliary ink tank 7 enters the ink tray 3 through the pipe 8 and the hose 9 until the weight of the ink tray 3 compresses the elastic telescopic rod 2 again to return to the initial compressed state. The valve plate 12 rotates and returns to its original position to close the pipe 8, thereby making the ink level in the ink tray 3 balanced and avoiding uneven adhesion of the ink roller to the ink.
