Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to a coating mixing mechanism for coating production. Background Technology

[0002] In the paint production process, the purpose of paint mixing is to fully disperse and uniformly mix various raw materials to ensure that the paint has consistent color, viscosity, and leveling properties. This directly affects the uniformity and stability of the paint. Traditional mixing equipment usually uses simple stirring blades or paddles, but materials easily adhere to the inner wall of the mixing tank, affecting uniformity. Moreover, since different batches of paint have different materials and properties, cleaning is required during production, but the mixing mechanism is inconvenient to disassemble and assemble. In addition, the stirring blades and stirring shaft are mostly designed as a single unit without bottom support. Therefore, during rotation, slight differences in the force on each stirring blade can easily cause the rotating shaft to become eccentric, posing a potential safety hazard to the equipment. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed coating mixing mechanism for coating production, which can solve the aforementioned defects.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-6 As shown, it includes a mixing tank 1, with a top cover 2 on the mixing tank 1. The top cover 2 and the mixing tank 1 are tightly sealed by a sealing ring to prevent powder leakage. The top cover 2 has multiple feeding hoppers 7, which are funnel-shaped to facilitate the uniform addition of powder. The bottom of the mixing tank 1 has a discharge pipe. The top cover 2 is installed on the mixing tank 1 by an array of fixing structures. The fixing structures ensure that the top cover 2 remains stable during high-speed mixing. A drive motor 9 is installed on the top cover 2. The drive motor 9 uses frequency conversion control and can adjust the mixing speed as needed. Inside the top cover 2... A rotating rod 10 is mounted on the side. The surface of the rotating rod 10 is polished to reduce frictional resistance. The shaft of the drive motor 9 is connected to the rotating rod 10 through a coupling to ensure the stability of power transmission. A rotating seat 11 is provided at the bottom of the mixing tank 1. The rotating seat 11 is connected to the mixing tank 1 through a sealed bearing to ensure flexible rotation. A stirring mechanism is installed on the rotating seat 11. The stirring mechanism can achieve all-round mixing of powder. A quick-connect structure is provided between the top of the rotating rod 10 and the rotating seat 11. The quick-connect structure facilitates the quick disassembly and maintenance of the stirring mechanism.

[0023] The mixing mechanism includes multiple bottom mixing blades 12 located on the outside of the rotating seat 11, which can effectively break up lumps in the powder and agitate the coating. Multiple connecting rods 13 are inclined outward above the rotating seat 11. The connecting rods 13 are made of high-strength steel to ensure that they do not deform during the mixing process. The upper end of the connecting rod 13 is connected to a scraper 14. The scraper 14 fits tightly against the inner wall of the mixing tank 1 to prevent the powder from adhering to the tank wall. A crossbar 16 is connected to the inner side of the scraper 14. The surface of the crossbar 16 is smooth to reduce powder residue. Limiting rings 15 are connected to the ends of the multiple crossbars 16. The limiting rings 15 are sleeved on the outside of the rotating rod 10 to ensure the stability of the mixing mechanism. Moreover, since the crossbars 16 are connected to the rotating seat 11 and the air speed is the same as that of the rotating rod 10, there will be no collision or friction between the limiting rings 15 and the rotating rod 10 during the rotation. At the same time, the rotating rod 10 provides auxiliary support for the limiting rings 15 to maintain the stability of the limiting rings 15, the crossbars 16 and the scraper 14.

[0024] Each crossbar 16 is equipped with an upper stirring blade 17, which can improve the mixing efficiency of powder.

[0025] The quick-connect structure includes a connector 19 located at the top of the rotating rod 10. The connector 19 adopts a cross design for easy and quick alignment. A connector 18 is connected above the rotating base 11. The connector 18 has a connector slot 20 that matches the shape of the connector 19. The opening of the connector slot 20 has a guide groove 21 that is larger than the connector slot 20. The guide groove 21 can guide the connector 19 to be quickly inserted into the connector slot 20, reducing collisions caused by misalignment during installation.

[0026] The fixed structure includes a connector 3 rotatably mounted on the side of the top cover 2. A connecting groove 4 is opened on the inner side of the connector 3. A connecting bolt 5 is installed on the mixing tank 1 facing outward. The connecting bolt 5 is made of high-strength stainless steel to ensure that it will not rust during long-term use. The connecting bolt 5 is located in the connecting groove 4. A connecting nut 6 is provided on the connecting bolt 5. A washer is placed inside the connecting nut 6 and abuts against the outside of the connector 3 to ensure a tight connection between the top cover 2 and the mixing tank 1.

[0027] Each feed hopper 7 is equipped with a feed cover 8, which is connected by a hinge for easy opening and closing. The inside of the feed cover 8 is equipped with a sealing gasket to prevent powder leakage.

[0028] The usage process of this utility model:

[0029] First, open the feed cover 8 and pour the material into the feed hopper 7. Material can be poured into multiple feed hoppers 7 at the same time to accelerate the feeding. Then close the feed cover 8 and start processing. The drive motor 9 drives the stirring mechanism to rotate through the rotating rod 10 and the rotating seat 11 to mix the paint. After mixing, the scraper 14 scrapes the inner wall of the mixing tank 1 to prevent adhesion. After mixing, the mixed paint can be discharged through the discharge pipe.

[0030] When cleaning or repairing the mixing tank 1, loosen the connecting nut 6, then rotate the connector 3 to the side to open it. Then lift the top cover 2 upwards, and pull the rotating rod 10 upwards to clean or repair the inside of the mixing tank 1. After the operation is completed, put the top cover 2 back on, insert the rotating rod 10 into the limiting ring 15, press it down, insert the connector 19 into the connector seat 18, and insert the connector 19 into the bottom of the connector slot 20. At this time, the top cover 2 is also in contact with the top of the mixing tank 1. Then rotate the connector 3 into place and tighten the connecting nut 6 to complete the installation.

[0031] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
