[0002] Water-based ink is referred to as water-based ink for short. Flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Water-based ink is particularly suitable for packaging and printing products with strict hygiene requirements such as tobacco, alcohol, food, beverage, medicine, children's toys, etc. Compared with solvent-based ink, the environmental protection performance of water-based ink has been further improved. It has less impact on the environment and mainly pollutes the workshop air.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, by arranging a rough surface slide groove, an open plate, an auxiliary hand wheel, a threaded rod, a movable block, a threaded sleeve, a connecting plate, a sliding groove, a first spring, a positioning clamping plate and a supporting roller, a staff member places the filling barrel between the two positioning clamping plates on the working base, and then rotates the threaded rod by twisting the auxiliary hand wheel, and utilizes the threaded cooperation between the threaded sleeve and the threaded rod to make the two movable blocks move oppositely along the threaded rod. With the movement of the movable block, the connecting plate will drive the positioning clamping plate to move, prompting the positioning clamping plate to contact with the filling barrel, so that the filling barrel can push the positioning clamping plate into the sliding groove, thereby enabling the positioning clamping plate to compress the first spring, and then continue to rotate the threaded rod so that the positioning clamping plate can clamp and fix the filling barrel, thereby preventing the filling barrel from sliding and deflecting during filling, and avoiding the leakage of water-based ink, and then pushing the connecting plate through the curved pull rod to prompt the opening plate to slide in the rough surface slide groove. At this time, the filling barrel will move together on the supporting roller, thereby assisting the staff to carry the filling barrel through the supporting roller, which is more labor-saving.

[0017] 2. In the present invention, a first motor, a threaded screw, a moving block, a guide sleeve, a discharge pipe, a hinged rod, a movable baffle, a smooth rod, a second spring and a groove are provided. When the filling barrel is pushed to the bottom of the discharge pipe, the threaded screw is driven to rotate by starting the first motor. As the threaded screw rotates, the moving block moves along the guide groove through the threaded cooperation between the guide sleeve and the threaded screw, prompting the discharge pipe to move downward. At this time, the hinged rod rotates on the fixed rod, thereby pushing the connecting block through the hinged rod, prompting the movable baffle to move along the smooth rod and compressing the second spring, so that the discharge pipe passes between the two movable baffles to complete the discharge and filling work. When the threaded screw is rotated in the opposite direction to raise the discharge pipe, the two movable baffles move toward each other and gradually close together through the rebound of the second spring and the pulling of the hinged rod, so that the ink is blocked by the movable baffle, and the splashed ink falls into the groove, preventing the ink from splashing on the working base and the supporting roller to pollute the working environment.

[0018] 3. In the present invention, a second motor, a stirring rod, a stirring plate, a fixed thin rod, a cleaning scraper, a discharge pipe and a control valve are provided. When working, the second motor is started to drive the stirring rod to rotate, so that the multiple stirring plates on the stirring rod can stir the water-based ink of different depths in the filling storage tank together, thereby ensuring the uniformity of the mixing of the water-based ink and avoiding the deposition and stratification of materials, thereby ensuring the product quality of the filled water-based ink. The staff can control the control valve on the discharge pipe to enable the water-based ink to flow out of the discharge pipe. While the stirring plate rotates, the stirring rod can drive the fixed thin rod to rotate, thereby driving the cleaning scraper on the fixed thin rod to rotate in the discharge pipe, thereby utilizing the frame-type cleaning scraper to scrape the water-based ink adhered to the inner wall of the discharge pipe to avoid residual accumulation. At the same time, the rotating cleaning scraper can prevent the water-based ink from clogging the discharge pipe, thereby ensuring smooth discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1-6 As shown, the present invention provides a technical solution: a water-based ink filling mechanism, including a working base 1, a plurality of support blocks 2 are connected below the working base 1, a total of four support blocks 2 are arranged in a rectangular array, an anti-skid pad 39 is connected below the support block 2, one side of the positioning clamp plate 14 is designed in an arc shape and is connected to a rubber pad 40, the working base 1 is supported by the plurality of support blocks 2, and the anti-skid pad 39 below the support block 2 can increase the friction with the ground, thereby avoiding sliding and improving the stability of placement, and when the positioning clamp plate 14 contacts with the filling barrel, the rubber pad 40 will be squeezed, thereby fitting and contacting with the filling barrel, thereby improving the stability of the clamping and avoiding sliding and deviation of the filling barrel.

[0028] A plurality of supporting rollers 3 are rotatably installed above the working base 1, a supporting column 4 is connected to the working base 1, a smooth rod 31 is connected to the supporting column 4, two movable baffles 32 are slidably connected to the smooth rod 31, connecting blocks 33 are connected on both sides of the movable baffle 32, a hinged rod 34 is rotatably connected to the connecting block 33 through a pin shaft, one end of the hinged rod 34 is rotatably connected to the fixed rod 30, and the downward movement of the discharge pipe 22 allows the two ends of the hinged rod 34 to rotate on the pin shaft and the fixed rod 30 respectively, so that the angle changes, so that the hinged rod 34 can push the movable baffle 32 to move along the smooth rod 31, and at this time the smooth rod 31 can guide and limit the movement of the movable baffle 32, so that the movable baffle 32 can move smoothly, prompting the two movable baffles 32 to gradually separate, so that the discharge pipe 22 can inject ink into the filling barrel.

[0029] Second springs 35 are sleeved on both ends of the smooth rod 31, one end of the second spring 35 is connected to the top of the smooth rod 31, and the other end of the second spring 35 is connected to the movable baffle 32. A groove 36 is provided on the movable baffle 32. When the two movable baffles 32 gradually separate, the movable baffle 32 will compress the second spring 35. Therefore, when the discharge pipe 22 moves upward, the rotation of the hinged rod 34 pulls the connecting block 33 and the rebound of the second spring 35, so that the two movable baffles 32 can gradually approach and close together, so that the movable baffle 32 can enclose the bottom of the discharge pipe 22 to prevent the residual ink in the discharge pipe 22 from dripping and polluting the working environment, and the dripping ink will fall into the groove 36.

[0030] A rough surface slide 5 is provided on the working base 1, an opening plate 6 is slidably connected in the rough surface slide 5, a threaded rod 7 is rotatably connected inside the opening plate 6, one end of the threaded rod 7 passes through the opening plate 6 and is connected to an auxiliary hand wheel 8, two movable blocks 9 are installed on the threaded rod 7, a threaded sleeve 10 is installed on the movable block 9, one side of the movable block 9 is connected to a connecting plate 11, one side of the connecting plate 11 is connected to a curved pull rod 26, a connecting rod 27 is slidably connected to the curved pull rod 26, the two curved pull rods 26 and the connecting rod 27 form a telescopic structure, and the auxiliary hand wheel 8 can facilitate work The personnel rotate the threaded rod 7 to drive the movable block 9 to move, and the telescopic curved pull rod 26 and the connecting rod 27 enable the curved pull rod 26 to adapt to the position width of the connecting plate 11 when the movable block 9 drives the connecting plate 11 to move, so that the personnel can push the positioning splint 14 through the curved pull rod 26 to drive the filling barrel to move, which is convenient and labor-saving. The groove walls on both sides of the rough surface chute 5 that contact with the opening plate 6 are relatively rough, so the contact friction between the opening plate 6 and the groove walls of the rough surface chute 5 can prevent the opening plate 6 and the positioning splint 14 from sliding accidentally.

[0031] A sliding groove 12 is provided inside the connecting plate 11, a first spring 13 is connected inside the sliding groove 12, a positioning clamping plate 14 is connected to one end of the first spring 13, a guide groove 15 is provided on the supporting column 4, a first motor 16 is installed above the supporting column 4, a threaded screw 17 is connected to the output shaft of the first motor 16, a moving block 18 is installed on the threaded screw 17, the threaded screw 17 is rotatably connected in the guide groove 15, a guide sleeve 28 is installed on the moving block 18, the guide sleeve 28 is threadedly matched with the threaded screw 17, and the moving block 18 is provided with a guide sleeve 28. 8 slides in the guide groove 15 and contacts with the groove wall of the guide groove 15. Through the threaded cooperation between the guide sleeve 28 and the threaded screw 17, when the first motor 16 rotates the threaded screw 17, the moving block 18 can be lifted and lowered along the guide groove 15. The mutual contact between the moving block 18 and the groove wall of the guide groove 15 enables the guide groove 15 to guide and limit the movement of the moving block 18, thereby preventing the moving block 18 from rotating and tilting during movement, so that the mounting platform 19 and the filling storage tank 20 can move up and down smoothly.

[0032] The movable block 18 is connected to a mounting platform 19, a filling storage tank 20 is mounted on the mounting platform 19, a material injection port 21 is connected to the top of the filling storage tank 20, a discharge pipe 22 is connected to the bottom of the filling storage tank 20, a control valve 29 is mounted on the discharge pipe 22, fixed rods 30 are connected to both sides of the discharge pipe 22, threads in opposite directions are arranged at both ends of the threaded rod 7, the threaded sleeve 10 is threadedly matched with the threaded rod 7, an opening groove is arranged on one side of the opening plate 6, the movable block 9 slides inside the opening plate 6 and contacts the inner wall, through The control valve 29 on the discharge pipe 22 can facilitate the staff to control the discharge amount, and the threads at both ends of the threaded rod 7 are in opposite directions, so that the threaded rod 7 can drive the two movable blocks 9 to move in opposite directions when it rotates. As the movable block 9 moves, the positioning clamp 14 will first contact the filling barrel, and then be pushed into the sliding groove 12 to compress the first spring 13 to buffer the contact, and then continue to rotate the threaded rod 7 until the first spring 13 can no longer continue to compress and move, so that the positioning clamp 14 can clamp and fix the filling barrel.

[0033] A second motor 23 is installed on the filling storage tank 20, and the output shaft of the second motor 23 is connected to a stirring rod 24, and a plurality of stirring plates 25 are connected to the stirring rod 24. One end of the stirring rod 24 is connected to a fixed thin rod 37, and a cleaning scraper 38 is connected to the fixed thin rod 37. The cleaning scraper 38 is frame-shaped as a whole and is in close contact with the inner wall of the discharge pipe 22. The stirring rod 24 and the fixed thin rod 37 are driven by the second motor 23 to rotate, so that the stirring plates 25 can stir the ink in the filling storage tank 20 to avoid ink deposition and stratification and improve the mixing effect. The rotation of the cleaning scraper 38 can prevent the ink from clogging the discharge pipe 22 and prevent the ink from sticking and remaining on the discharge pipe 22.

[0034] The working principle of the present invention is:

[0035] During operation, the opening plate 6 is caused to be located at the side of the rough surface slide 5 away from the supporting column 4. Then the staff places the filling barrel between the two positioning clamps 14 and rotates the threaded rod 7 by twisting the auxiliary hand wheel 8. Due to the threads at both ends of the threaded rod 7 in opposite directions and the threaded sleeve 10 and the threaded rod 7, the two movable blocks 9 can move in opposite directions along the threaded rod 7, causing the connecting plate 11 to drive the positioning clamp 14 to move. With the movement of the movable block 9, the positioning clamp 14 will first contact with the filling barrel, so that the positioning clamp 14 is pushed into the sliding groove 12 by the filling barrel, and then the positioning clamp 14 can compress the first spring 13, so as to buffer the contact;

[0036] Then, the threaded rod 7 is rotated continuously to make the positioning clamping plate 14 completely compress the first spring 13, so that the first spring 13 cannot be moved and compressed, so that the two positioning clamping plates 14 can clamp and fix the filling barrel, and then the connecting plate 11 is pushed by the curved pull rod 26 to make the opening plate 6 slide in the rough surface slide groove 5. At this time, the filling barrel will move together on the supporting roller 3, so that the supporting roller 3 assists the staff to carry the filling barrel and move the filling barrel to the bottom of the discharge pipe 22. Then, the first motor 16 is started to rotate the threaded screw 17. At this time, the moving block 18 will move along the guide groove 15 through the threaded cooperation between the guide sleeve 28 and the threaded screw 17, so as to make the discharge pipe 22 move downward;

[0037] At this time, the hinged rod 34 will rotate on the fixed rod 30, thereby pushing the connecting block 33 through the hinged rod 34, prompting the movable baffle 32 to move along the smooth rod 31 and compressing the second spring 35, so that the discharge pipe 22 passes between the two movable baffles 32 to complete the discharge and filling work, and then the threaded screw 17 is rotated in the opposite direction to move the discharge pipe 22 upward. At this time, the two movable baffles 32 move towards each other and gradually close together through the rebound of the second spring 35 and the pulling of the hinged rod 34, so that the dripping ink is blocked by the movable baffle 32, and the second motor 23 can drive the stirring rod 24 to rotate during operation;

[0038] The multiple stirring plates 25 on the stirring rotating rod 24 are urged to stir the ink in the filling storage tank 20 to ensure the uniformity of the ink mixing and avoid material deposition and stratification. The stirring rotating rod 24 can drive the fixed thin rod 37 to rotate, thereby causing the cleaning scraper 38 on the fixed thin rod 37 to rotate. The frame-type cleaning scraper 38 is used to scrape the inner wall of the discharge pipe 22 to avoid residual accumulation. At the same time, the rotating cleaning scraper 38 prevents the ink from clogging the discharge pipe 22 to ensure smooth discharge.
