[0002] In daily life, the stirring paddle is the core component of mixing equipment. It is installed at the end of the stirring shaft. Its main function is to mix, stir, disperse, transfer heat, or promote chemical reactions of liquid, solid, or gaseous materials in the container through rotational motion. Simply put, the stirring paddle is like a rotating "paddle" in the liquid. Its movement drives the material to flow, so that different components are fully mixed and evenly, or to accelerate the reaction speed or prevent sedimentation.
[0003] Currently, mixing equipment is required in food processing. However, the mixing blades of existing mixing equipment are mostly welded as one piece or fixed with screws or other structures. This method is not conducive to disassembling and replacing the mixing blade structure. Since the mixing blade is used for mixing for a long time, it is very easy to be damaged. Replacing the entire mixing blade would increase production costs. Utility Model Content

[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] Please see Figures 1 to 9 This utility model provides a technical solution: a detachable, quick-cleaning stirring paddle assembly for food processing, including a stirring rod 1, a fixed plate 2 fixedly connected to the bottom of the stirring rod 1, an upper cover 4 provided on the outer side of the stirring rod 1, four positioning limit blocks 11 fixedly connected to the bottom of the upper cover 4, and positioning shafts 12 fixedly connected to the bottom of each of the four positioning limit blocks 11, four installation limit blocks 8 provided inside the fixed plate 2, a lower cover 6 threadedly connected to the bottom of the fixed plate 2, and four internal hexagon bolts 7 provided inside the lower cover 6, which are respectively threadedly connected to the corresponding positioning shafts 12. The above is achieved by setting the fixed plate 2, the upper cover 4, and the positioning limit blocks... 11. The positioning shaft 12, the mounting limit block 8, the lower cover 6, and the internal hex bolt 7 enable the threaded connection between the positioning shaft 12 and the internal hex bolt 7, allowing for quick installation and disassembly of the stirring blade 9 on the mounting limit block 8. This reduces installation and disassembly time and allows for easy replacement of any damaged stirring blade 9 based on actual working conditions, thus reducing production costs. Furthermore, the cooperation between the positioning limit block 11 and the mounting limit block 8 ensures the stability of the stirring blade 9 during stirring operations. The cooperation between the upper cover 4, the fixing plate 2, and the lower cover 6 effectively ensures the stability of the structural positions.
[0023] The outer side of the stirring rod 1 is threaded with a fastening threaded cover 3, which is rotatably connected to the upper cover 4, allowing the upper cover 4 to be moved easily by rotating the fastening threaded cover 3.
[0024] The bottom of the upper cover 4 is rotatably connected to the upper merging cover 10, and the top of the lower cover 6 is rotatably connected to the lower merging cover 5. The upper merging cover 10 and the lower merging cover 5 can be merged to complete the protection and limiting of the installation limiting block 8 and the stirring blade 9.
[0025] The fixed plate 2 has four sliding grooves 13 inside. The inner walls of the four sliding grooves 13 are slidably connected to sliders 14. One side of the slider 14 is fixedly connected to a spring 15 inside the sliding groove 13. The side of the slider 14 away from the spring 15 is fixedly connected to a hemispherical block 16, which can facilitate the installation of the installation limiting block 8 and facilitate the removal of the installation limiting block 8 by using the hemispherical block 16 during disassembly.
[0026] Four installation limit blocks 8 are fixedly connected to one side of a stirring blade 9, which can stir food raw materials.
[0027] Specifically, when it is necessary to replace one of the stirring blades 9 or other structures, first rotate and remove the four hex bolts 7, which will separate the hex bolts 7 from the positioning shaft 12. Then rotate the lower merging cover 5 to separate it from the fixed plate 2, and then remove the lower cover 6 and the lower merging cover 5. Then rotate the fastening threaded cover 3 to move it on the stirring rod 1, which will drive the upper cover 4 and the upper merging cover 10 to move upward, so that the four positioning limit blocks 11 at the bottom of the upper cover 4 will drive the positioning shaft 12 to separate from the installation limit block 8. After moving the upper merging cover 10 to the required position, the installation limit block 8 can be moved upward within the fixed plate 2, which will push the hemispherical block 16, so that the moving hemispherical block 16 will drive the slider 14 to slide within the slide groove 13. The sliding slider 14 is compressed, which will cause the hemispherical block 16 to move away from the installation limit block 8. Then the installation limit block 8 can be removed and replaced. When it is necessary to install the stirring blade 9, the above disassembly operation is performed in reverse.
