[0021] 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.

[0022] Example 1: Please refer to Figure 1 -

[0023] Figure 4 A mixing tank for water-based paint production includes a tank body 1, a sealing cover 2 is clamped on the top of the tank body 1, the tank body 1 and the sealing cover 2 are fixedly connected by a locking structure 3, a feed pipe 4 is fixedly installed on the top surface of the sealing cover 2, a stirring structure 5 for mixing raw materials is rotatably installed inside the sealing cover 2 through a bearing, a discharge pipe 6 is fixedly connected to the bottom surface of the tank body 1, and a valve for limiting the flow rate is fixedly installed on the outer wall of the discharge pipe 6;

[0024] The stirring structure 5 includes a rotating shaft 501, which is rotatably connected to the sealing cover 2 via a bearing. The outer wall of the rotating shaft 501 is provided with three rotating rings 502 rotatably sleeved by the bearing. Both sides of each rotating ring 502 are rotatably connected to stirring paddles 503 via pins. The top of each rotating ring 502 is rotatably connected to an adjustment structure for adjusting the deployment angle of the stirring paddles 503 according to the viscosity of the raw material.

[0025] The adjustment structure includes a fixed ring 504, which is fixedly sleeved on the outer wall of the rotating shaft 501. The outer wall of the fixed ring 504 is fixedly sleeved with a pull rope 505 for driving the stirring paddle 503 to rotate the angle. The end of the pull rope 505 away from the fixed ring 504 is rotatably connected to the stirring paddle 503.

[0026] Specifically, the outer wall of the fixing ring 504 is provided with a winding groove for winding the pull rope 505, and the end of the pull rope 505 close to the fixing ring 504 is fixedly wound in the winding groove. The top of the stirring paddle 503 is fixedly installed with a connecting buckle 506, and the connecting buckle 506 is rotatably connected to one end of the pull rope 505.

[0027] More specifically, the rotating ring 502 and the fixed ring 504 are driven to rotate synchronously by the rotating shaft 501, and the stirring paddle 503 rotates along with the rotating ring 502. When the stirring material is too viscous, the stirring paddle 503 is subjected to resistance, causing the rotation speed of the rotating ring 502 to decrease, so that a speed difference is generated between the rotating ring 502 and the fixed ring 504, causing the pull rope 505 to gradually surround the fixed ring 504.

[0028] The stirring paddle 503 is wound around the stirring paddle 503 and its length is gradually shortened, thereby pulling the stirring paddle 503 to rotate and tilt toward the rotating shaft 501 with the pin inserted between the stirring paddle 503 and the rotating ring 502 as the fixed point, so as to shrink the expansion angle of the stirring paddle 503 and reduce the stirring range of the stirring paddle 503, thereby avoiding wear of the device due to excessive resistance, ensuring that the device always maintains a good stirring effect, and ensuring the smooth progress of the entire stirring process;

[0029] More specifically, after the subsequent coating is stirred and mixed gradually and uniformly, the resistance to the stirring paddle 503 gradually decreases, and the rotation speed of the rotating ring 502 is accelerated. Under the gravity of the stirring paddle 503, the pull rope 505 is pulled downward to expand and extend, thereby restoring the stirring paddle 503 to a horizontal state, allowing the stirring paddle 503 to continue stirring at a more appropriate angle and posture, thereby further improving the stirring efficiency, allowing the coating to be mixed more fully and evenly, and providing a higher quality material foundation for subsequent production processes;

[0030] In order to reduce the resistance on the stirring paddle 503, the inner cavity of the stirring paddle 503 is fixedly connected to a crossbar 507. The outer wall of the crossbar 507 is rotatably sleeved with a flip block 508. The interior of the stirring paddle 503 is provided with a rotation groove for providing rotation for the flip block 508, and the flip block 508 is located in the rotation groove.

[0031] Specifically, when the stirring paddle 503 encounters resistance, the flip block 508 inside the stirring paddle 503 flips from its original vertical state to a horizontal state under the push of the resistance, thereby opening the rotating groove to facilitate the passage of the raw materials through the stirring paddle 503, thereby reducing the impact of the resistance on the stirring paddle 503;

[0032] More specifically, a counterweight is fixedly mounted on one end of the inner cavity of the flip block 508. When the resistance to the flip block 508 is reduced, the flip block 508 is flipped again under the action of the counterweight, from a horizontal state to a vertical state, thereby restoring the stirring ability of the stirring paddle 503.

[0033] The stirring structure 5 also includes a connecting block 509, which is fixed at the bottom end of the rotating shaft 501. A plurality of rotating blades 510 are fixedly connected to the outer wall of the connecting block 509. Each rotating blade 510 itself is provided with a twisting angle. The connecting block 509 is driven by the rotating shaft 501 to control the rotation of the plurality of rotating blades 510. The twisting angle of the rotating blades 510 can generate axial flow, lift the paint at the bottom of the tank body 1 upward, promote the overall circulation of the paint, and cooperate with the stirring paddle 503 to generate radial flow, enhance the mixing effect of the paint in the horizontal direction, effectively ensure that the paint can be fully stirred in all directions, and reduce the stirring dead angle.

[0034] Specifically, a motor 511 for providing rotational power to the rotating shaft 501 is fixedly mounted on the top surface of the sealing cover 2 , and an output end of the motor 511 is fixedly connected to the top end of the rotating shaft 501 .

[0035] Example 2: Please refer to Figure 1 、 Figure 2 The locking structure 3 includes an upper sealing sleeve 301 and a lower sealing sleeve 302. The upper sealing sleeve 301 is fixed at the bottom end of the sealing cover 2, and the lower sealing sleeve 302 is fixed at the top end of the tank body 1. The upper sealing sleeve 301 and the lower sealing sleeve 302 are fixedly connected by a locking rod 303.

[0036] Specifically, the top end of the locking rod 303 passes through the upper sealing sleeve 301 , and the outer wall thread sleeve of the locking rod 303 is provided with a locking sleeve 304 , and the bottom end of the locking rod 303 is fixedly connected to the lower sealing sleeve 302 .

[0037] See also Figure 1 、 Figure 2 The top end of the feed pipe 4 is rotatably connected to the cover plate through a pin shaft, and the inner cavity of the cover plate is rotatably installed with a rotating bolt for fixing the cover plate through a bearing, and the bottom end of the rotating bolt passes through the cover plate and is threadedly connected to the feed pipe 4.

[0038] See also Figure 1 、 Figure 2 A support frame 7 is fixedly installed at the bottom end of the tank body 1, and a regulator for adjusting the horizontal state of the tank body 1 is threadedly connected to the bottom end of the support frame 7.

[0039] The working principle of this utility model is:

[0040] First, inject the paint into the interior of the tank body 1 from the feed pipe 4, then close the cover plate and rotate the rotary bolt to fix the cover plate and the feed pipe 4 to prevent splashing when the paint is subsequently stirred;

[0041] The starting motor 511 drives the rotating shaft 501 to rotate, and the rotating shaft 501 is connected to the rotating ring 502 to drive the stirring paddle 503 to rotate to stir the paint. When the paint is too viscous, the stirring paddle 503 encounters resistance, causing the rotation speed of the rotating ring 502 to decrease, so that a speed difference is generated between the rotating ring 502 and the fixed ring 504, causing the pull rope 505 to gradually surround the fixed ring 504.

[0042] The stirring paddle 503 is wound around the stirring paddle 503 and its length is gradually shortened, thereby pulling the stirring paddle 503 to rotate and tilt toward the rotating shaft 501 with the pin inserted between the stirring paddle 503 and the rotating ring 502 as the fixed point, so as to shrink the spreading angle of the stirring paddle 503 and reduce the stirring range of the stirring paddle 503. At the same time, the turning block 508 inside the stirring paddle 503 is turned from the original vertical state to the horizontal state under the push of the resistance, thereby opening the rotating groove to facilitate the raw material to pass through the stirring paddle 503, thereby reducing the influence of the resistance on the stirring paddle 503.

[0043] The rotating shaft 501 drives the connecting block 509 to control the rotation of the multiple rotating blades 510. The twisting angle of the rotating blades 510 can generate axial flow, which lifts the paint at the bottom of the tank 1 upward, promotes the overall circulation of the paint, and ensures that the paint can be fully stirred in all directions.

[0044] Finally, the mixed paint is discharged from the discharge pipe 6, and the locking sleeve 304 is twisted to rotate around the locking rod 303, thereby loosening the tight connection between the upper sealing sleeve 301 and the lower sealing sleeve 302, so that the sealing cover 2 can be opened to clean the inside of the device.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
