Description

Technical Field

[0001] This utility model belongs to the field of plastic powder production technology, specifically relating to a manual mixer that is easy to clean. Background Technology

[0002] Powder coating is a thermosetting powder coating used for electrostatic spraying. Before production based on demand, manufacturers will create samples to avoid resource waste during large-scale production. After the sample passes various performance tests and is approved by the customer, formal production can begin. Sampling includes a mixing process, during which operators manually or with a mixer thoroughly mix the weighed materials.

[0003] Depending on actual needs, some factories choose smaller, simpler manual mixers for prototyping. Manual mixers consist of a support frame, a mixing hopper, and a rotating shaft. The rotating shaft is fixed to the mixing hopper, which contains blades to improve mixing efficiency. The rotating shaft passes through and is rotatably connected to the support frame. An operating handle is located at the end of the rotating shaft, allowing the operator to rotate the mixing hopper. However, due to size limitations, the existing blades are fixed to the mixing hopper, making thorough cleaning difficult and prone to material residue, which can affect subsequent mixing. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a manual mixer that is easier to clean than existing technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a manual mixer that is easy to clean, comprising a support frame, a material cylinder, and a rotating shaft. The rotating shaft passes through the support frame and is rotatably connected to the support frame. A flow divider is provided inside the material cylinder. The material cylinder includes a main body and a cover. The rotating shaft is fixed to the main body. An operating handle is provided at the end of the rotating shaft away from the main body. The main body and the cover are fixed by a buckle. The main body includes a cylindrical central cavity. The flow divider includes a mounting frame disposed in the central cavity, an extension rod that fixes the mounting frame and the cover facing the central cavity, and blades fixed on the mounting frame.

[0006] Using the above scheme, the discharge port of the material cylinder is located on the main body, and a butterfly valve can be installed at the discharge port. When cleaning is required, the fasteners are released, and the cover is removed from the main body. At this time, the diverter moves away from the central cavity with the cover. The central cavity is unobstructed, facilitating cleaning of the central cavity, and the diverter is exposed outside the cover, facilitating cleaning of the diverter.

[0007] Preferably, the blades are welded to the mounting bracket, but the blades can also be fixed to the mounting bracket with bolts as required.

[0008] As a further feature of this utility model, the mounting frame is radially oriented, the center of the mounting frame coincides with the axis of the central cavity, the mounting frame includes at least two mounting rods, the number of extension rods is the same as the number of mounting rods, the end of the extension rod away from the cover is fixed to the mounting rod, the number of blades is greater than or equal to the number of mounting rods, and the blades are evenly distributed on each mounting rod, the blades are arranged between the axis of the extension rod and the central cavity.

[0009] The above solution ensures that the mounting frame remains stable during mixing, resulting in better mixing.

[0010] As a further feature of this invention, the blade is parallel to the axis of the central cavity or has an angle of less than 45 degrees with it.

[0011] As a further feature of this invention, each mounting rod is provided with at least two blades, and there is an included angle between the blades on the same mounting rod.

[0012] As a further feature of this utility model, when the cover is placed on the main body, all the blades are located inside the central cavity.

[0013] As a further feature of this utility model, the cover includes a frustum-shaped upper cavity, and the main body has a frustum-shaped lower cavity on the side away from the cover, and the extension rod is fixed to the inner wall of the upper cavity.

[0014] The above method can improve mixing efficiency.

[0015] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise specified, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Specific embodiments of this utility model are shown in the accompanying drawings.

[0023] A manual mixer that is easy to clean includes a support frame 1, a main body 2, a cover 3, a rotating shaft 4, and a flow divider 5. The rotating shaft 4 passes through the support frame 1 and is rotatably connected to the support frame 1. The rotating shaft 4 is fixed to the main body 2. An operating handle 6 is provided at the end of the rotating shaft 4 away from the main body 2. The main body 2 and the cover 3 are fixed by a buckle 7. The cover 3 includes a frustum-shaped upper cavity 31. The main body 2 includes a cylindrical middle cavity 21 and a frustum-shaped lower cavity 22. The flow divider 5 includes a mounting bracket 51 disposed in the middle cavity 21, an extension rod 52 that fixes the mounting bracket 51 to the inner wall of the upper cavity 31, and a blade 53 fixed on the mounting bracket 51.

[0024] The lower cavity 22 is provided with a discharge hole. When cleaning is required, the fastener 7 is released, and the cover 3 is removed from the main body 2. At this time, the diverter 5 moves away from the middle cavity 21 along with the cover 3. The middle cavity 21 is unobstructed, which facilitates cleaning of the middle cavity 21. The diverter 5 is exposed outside the cover 3, which facilitates cleaning of the diverter 5. In this embodiment, the blade 53 is welded to the mounting bracket 51.

[0025] The mounting frame 51 is radially oriented, with its center coinciding with the axis of the central cavity 21. In this embodiment, the mounting frame 51 includes three mounting rods 511, with adjacent mounting rods 511 having the same included angle. The number of extension rods 52 is the same as the number of mounting rods 511, and the end of the extension rod 52 away from the cover 3 is fixed to the mounting rod 511. In this embodiment, the number of blades 53 is greater than the number of mounting rods 511, and the blades 53 are evenly distributed on each mounting rod 511. The blades 53 are positioned between the axis of the extension rod 52 and the central cavity 21. This ensures that the mounting frame 51 remains stable during mixing, resulting in better mixing.

[0026] In this embodiment, the blades 53 are parallel to the axis of the central cavity 21. Two blades 53 are provided on one mounting rod 511, and there is an included angle between the blades 53 on the same mounting rod 511. In this embodiment, the two blades 53 on the same mounting rod 511 have different shapes, sizes, and orientations, and the thickness of the blades 53 gradually decreases from the connection point with the mounting bracket 51 to both ends. When the cover 3 is placed on the main body 2, all blades 53 are located within the central cavity 21. This improves mixing efficiency.

[0027] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
