Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides an automatic ink mixing device, including a cylinder 1. A cover plate 2 is bolted to the top of the cylinder 1. A clearance groove 3 is formed on the upper surface of the cover plate 2. A ring frame 4 is bolted to the clearance groove 3. Multiple nozzles 9 are provided on the ring frame 4. A ring tube 8 is welded to the top of the multiple nozzles 9. Two symmetrical fixing seats 5 are bolted to the upper surface of the cover plate 2. Each fixing seat 5 is equipped with a water pump 6 to pressurize water. The water pump 6 is connected to an external water pipe. A T-shaped pipe bracket 7 is provided at one end of the water pump 6, and one end of the T-shaped pipe bracket 7 is fixedly connected to the ring tube 8. A fixing device is bolted to the upper surface of the cover plate 2. The upper surface of the second base 10 is fixedly connected to the motor 11 by bolts. One end of the output shaft of the motor 11 passes through the lower surface of the second base 10 and is keyed to the rotating shaft 14. The bottom end of the rotating shaft 14 passes through the cover plate 2 and extends into the cylinder 1. The part of the rotating shaft 14 that extends into the cylinder 1 is equipped with a stirring component for stirring the ink. After the device completes one ink mixing cycle, the inside of the cylinder 1 can be cleaned by the multiple nozzles 9 and the annular tube 8. The water pump 6 can pressurize the water to better clean the inside. The annular frame 4 can also be disassembled to facilitate the disassembly and maintenance of the nozzles 9 and prevent the cleaning effect from deteriorating due to blockage.

[0024] In this invention, the stirring assembly is a fixed frame 15, which is bolted to the outer circumference of the rotating shaft 14 located inside the cylinder 1. Two perforated plates 16 are bolted to the fixed frame 15, and the two perforated plates 16 are symmetrically arranged on both sides of the rotating shaft 14. The stirring assembly accelerates the mixing of ink colors, significantly reducing mixing time and increasing the mixing efficiency of the device. Furthermore, the perforated plates 16 allow ink to pass through the holes during stirring, further increasing mixing efficiency. A straight pipe 12 passes through the lower surface of the cover plate 2 at the bottom of the T-shaped tube frame 7, and is connected to the T-shaped tube frame 7. Multiple equally spaced nozzles 13 are provided on the straight pipe 12. The straight pipe 12 and nozzles 13 allow for cleaning of the rotating shaft 14 and the stirring assembly during cleaning of the inside of the cylinder 1, preventing ink adhering to them from affecting subsequent mixing.

[0025] To facilitate cleaning of the inner wall of the cylinder 1, a set of sliding rods 18 are slidably connected to both sides of the fixing frame 15, with multiple rods in each set. One end of each sliding rod 18 is fixedly connected to a scraper 19 by bolts, and one side of the scraper 19 contacts the inner circumference of the cylinder 1. The scraper 19 can scrape off the ink adhering to the inner wall of the cylinder 1, thereby further increasing the efficiency of cleaning the inside of the device. Multiple springs 20 are welded to both sides of the fixing frame 15, and the other end of each spring 20 on the same side is fixed to one side of the scraper 19. The springs 20 are all sleeved on the outside of the sliding rods 18. The 20 can always apply elastic force to the scraper 19, so that the scraper 19 can always be in contact with the inner wall of the cylinder 1, avoiding the situation where the scraper 19 cannot be in close contact with the inner wall of the cylinder 1 due to wear. The bottom of the rotating shaft 14 is provided with multiple arc-shaped scrapers 17, which are arranged in a circular array. The lower surface of the multiple arc-shaped scrapers 17 is in contact with the bottom inner wall of the cylinder 1. The ink on the bottom inner wall of the cylinder 1 can be scraped off by the provided arc-shaped scrapers 17. The upper surface of the cover plate 2 is fixedly connected to the feed pipe by bolts. The bottom outer wall of the cylinder 1 is provided with a discharge pipe, and both the feed pipe and the discharge pipe are connected to the inside of the cylinder 1.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to clean the inside of the cylinder 1, water is supplied through an external water pipe. The water enters the water pump 6 through the water pipe for pressurization, and then is transported to the annular pipe 8 and the straight pipe 12 through the T-shaped pipe frame 7. Part of the water is sprayed onto the inner wall of the cylinder 1 through the nozzle 19 on the annular pipe 8, and the other part is sprayed onto the stirring assembly through the nozzle 213 on the straight pipe 12 to clean the inside of the cylinder 1.

[0028] S2: During the cleaning process, the motor 11 is started to drive the rotating shaft 14 to rotate, which in turn drives the fixed frame 15 to rotate, and drives the scraper 19 that is in contact with the inside of the cylinder 1 to rotate, thereby cleaning the inner wall of the cylinder 1. At the same time, as the rotating shaft 14 rotates, it also drives the arc-shaped scraper 17 fixed at the bottom to scrape the bottom inner wall of the cylinder 1, thereby speeding up the cleaning efficiency of the device.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
