[0021] Example 1

[0022] like Figures 1-3 As shown in the figure, the water-based paint raw material mixing equipment proposed in this embodiment includes a mixing tank 1, a stirring mechanism, a double cone 9, and a scraper 10.

[0023] The upper and lower ends of the mixing box 1 are respectively connected to the feed hopper 6 and the discharge pipe 7. The discharge pipe 7 is equipped with a valve 8, which can be a solenoid valve or a manual valve. A connecting ring 3 is provided on the outer periphery of the mixing box 1. A bracket 4 is provided at the bottom of the mixing box 1. A support ring 2 is provided on the bracket 4. Multiple first elastic components are connected between the support ring 2 and the connecting ring 3. The first elastic components include a guide rod 17, a first spring 18 and a limiting block 19. The guide rod 17 passes through the connecting ring 3 and its bottom end is connected to the support ring 2. The limiting block 19 is provided at the top of the guide rod 17. The first spring 18 is sleeved on the guide rod 17.

[0024] The stirring mechanism includes a rotating tube 14 rotatably mounted on a mixing chamber 1, a power assembly for driving the rotating tube 14 to rotate, and multiple stirring blades 20 mounted on the rotating tube 14. The stirring blades 20 are located inside the mixing chamber 1. The power assembly includes a motor 11, a gear 12, and a gear ring 13. The motor 11 is mounted on the mixing chamber 1, the gear 12 is mounted on the output shaft of the motor 11, and the gear ring 13 is mounted on the outer periphery of the rotating tube 14 and is meshed with the gear 12.

[0025] One or more scraper rods 10 are provided, and the scraper rods 10 are located inside the mixing tank 1. A second elastic component is connected between the scraper rods 10 and the rotating tube 14. The second elastic component includes a sleeve 211, a movable rod 212, a second spring 213, and a piston plate 214. The sleeve 211 and the movable rod 212 are respectively connected to the rotating tube 14 and the scraper rod 10. The end of the movable rod 212 is movably located inside the sleeve 211 and connected to the piston plate 214. The second spring 213 is sleeved and installed on the piston plate 214. The second spring 213 is located on the inner side of the sleeve 211 on the outer periphery of the moving rod 212; a sealing ring 23 is installed at the end of the sleeve 211, and the sealing ring 23 is set to prevent paint from entering the inside of the sleeve 211; a crossbar 22 is connected to the scraper 10, and the crossbar 22 is arranged radially along the mixing box 1; a double cone 9 is located at the inner center of the mixing box 1, and a vertical rod 15 is connected to the double cone 9. The vertical rod 15 passes through the rotating tube 14, and a connecting frame 16 is connected between the vertical rod 15 and the support ring 2.

[0026] Specifically, during production, the raw materials for producing water-based paint are fed into the mixing tank 1. As the amount of material inside the mixing tank 1 increases, the first spring 18 is gradually compressed, causing the mixing tank 1 to gradually move downwards. The movement of the mixing tank 1 drives the movement of the rotating tube 14, the second elastic component, the scraper 10, and the crossbar 22. The end of the crossbar 22 contacts the lower part of the double cone 9. As the crossbar 22 continues to move, it gets closer and closer to the center of the mixing tank 1. At this point, the scraper 10 separates from the inner wall of the mixing tank 1. After the material feeding is completed, the set power... The component drives the rotating tube 14 to rotate. It should be added that the technical solution also includes a controller 5, which is a PLC controller. The controller 5 controls the operation of multiple devices. The rotation of the rotating tube 14 drives the rotation of the stirring blade 20, the second elastic component, the scraper 10 and the crossbar 22, which can realize the stirring of materials. During the stirring operation, since the scraper 10 does not directly contact the inner wall of the mixing box 1, the resistance encountered by the equipment during the stirring process is reduced, the working efficiency of the power component is improved, and wear on the scraper 10 and the inner wall of the mixing box 1 can also be avoided.

[0027] After the mixing is completed, valve 8 is opened to allow the water-based paint to be discharged from the discharge pipe 7. As the material decreases, the mixing box 1 begins to move upward. At this time, the crossbar 22 gradually moves upward. The end of the crossbar 22 is limited by the double cone 9, causing the crossbar 22 and the scraper 10 to gradually move towards the inner wall of the mixing box 1. When the material inside the mixing box 1 is about to be emptied, the mixing box 1 rises to the limit position, and at this time the scraper 10 contacts the inner wall of the mixing box 1, thereby enabling the scraping of the residual paint on the inner wall of the mixing box 1. It should be noted that, in order to further reduce wear, a rubber strip is installed on the scraper 10.

[0028] Example 2

[0029] like Figure 2 As shown in this embodiment, the water-based paint raw material mixing device is different from that in Embodiment 1. In this embodiment, the lower part of the mixing box 1 is a conical funnel-shaped structure. This structure makes it easier for the material inside the mixing box 1 to accumulate at the bottom, thus facilitating material discharge. It should be added that the lower part of the scraper 10 is a bent structure. When the upper part of the scraper 10 contacts the upper inner wall of the inner cavity of the mixing box 1, the lower part of the scraper 10 contacts the lower inner wall of the inner cavity of the mixing box 1.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
