Description

Technical Field

[0001] This utility model relates to the technical field of paint production equipment, specifically a paint mixing and feeding device. Background Technology

[0002] In the paint production process, the uniformity of raw material mixing directly affects the quality of the paint film and product performance. Traditional paint mixing equipment mostly adopts a single stirring structure, directly adding liquid or powdered raw materials into the mixing tank for stirring. However, powdered raw materials such as titanium dioxide and talc are prone to clumping, and direct addition to the mixing tank will lead to uneven dispersion, requiring external pre-grinding equipment. Liquid raw materials such as resins and solvents may separate due to prolonged standing, affecting the accuracy of the formulation ratio.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0019] Specifically, the dispersion and stirring structure includes a stirring shaft 4, on which multiple central stirring rods 5 are installed. Two scrapers 6 are symmetrically installed on the multiple central stirring rods 5. The two scrapers 6 are movably attached to the lower wall of the vessel body 1. The stirring shaft 4 is movably inserted into the center of the upper wall of the vessel cover 3. A driven bevel gear 7 is fixedly mounted on the stirring shaft 4 at the outer part of the vessel body 1. A drive unit is installed on the driven bevel gear 7.

A side stirring rack and a side dispersing rack are provided on the box cover 10. The side stirring rack and the side dispersing rack are connected to the central gear 8.

[0020] It should be noted that the driven bevel gear 7 rotates through the operation of the drive unit, which in turn drives the stirring shaft 4, multiple intermediate stirring rods 5, two scrapers 6 and the central gear 8 to rotate. The rotation of the stirring shaft 4, multiple intermediate stirring rods 5 and two scrapers 6 is used to mix the paint raw materials in the kettle body 1.

[0021] Specifically, both the side stirring rack and the side dispersing rack include a side rotating shaft 11. A drive gear 12 is fixedly mounted on the side rotating shaft 11. A connecting gear 13 meshes with the drive gear 12. A connecting shaft 14 is fixedly inserted into the connecting gear 13. The connecting shaft 14 is movably inserted into the box cover 10.

Multiple cutters 16 rotate to disperse the powdered raw materials, prevent clumping, improve the mixing efficiency of the raw materials, and ensure the mixing quality of the subsequent raw materials. In the actual design of the device, the number of dispersion boxes 9 and the selection and installation of the side stirring racks and side dispersing racks on them are determined according to the quantity and type of paint raw materials.

[0023] Specifically, the drive unit includes a drive bevel gear 17, which meshes with a driven bevel gear 7. A motor 18 is mounted on the drive bevel gear 17 and is fixedly mounted on the upper wall of the vessel cover 3.

[0024] It should be noted that the operation of motor 18 drives the drive bevel gear 17 to rotate, which in turn drives the driven bevel gear 7 to rotate the stirring shaft 4, providing power for the operation of the device.
