Description

Technical Field

[0001] This utility model relates to the field of premixed powder mixing devices, and more specifically, to a premixed powder raw material proportioning and mixing device. Background Technology

[0002] Premixed powder ingredient proportioning and mixing devices typically employ a vertical or horizontal mixer structure, made of stainless steel, and equipped with motor-driven spiral blades or paddle mixers. Through mechanical rotation, dry ingredients such as flour, powdered sugar, and leavening agents are physically mixed.

[0003] Existing premixed powder raw material mixing devices typically use direct addition when mixing small amounts of additives. However, since these components account for a small proportion, it is difficult to quickly and evenly disperse them using only the shearing and diffusion effects of conventional mixers. Often, it is necessary to extend the mixing time to achieve the desired effect.

[0005] To overcome the above deficiencies, this utility model provides a premixed powder raw material proportioning and mixing device, which aims to improve the problems mentioned in the background.

[0022] Example, refer to Figures 1-4 A premixed powder raw material proportioning and mixing device includes a base 1, a mixing cylinder 2 fixedly connected to the top of the base 1, a top cover 3 fixedly connected to the top of the mixing cylinder 2, a stand 5 fixedly connected to the top of the base 1, a motor 6 fixedly connected to the top of the stand 5, a main shaft 7 fixedly connected to the output shaft of the motor 6, the main shaft 7 passing through the top cover 3 and rotatably connected to the top cover 3, a lower blade 8 and an upper blade 9 fixedly connected to the main shaft 7, the lower blade 8 being disposed at the bottom of the main shaft 7, a plurality of plate-type spiral blades 10 fixedly connected between the lower blade 8 and the upper blade 9, a support rod 11 fixedly connected to the side wall of the main shaft 7, the end of the support rod 11 being fixedly connected to the plate-type spiral blades 10, a protective cover 13 fixedly connected to the top of the top cover 3, an intermittent feeding component and a striking component being disposed on the top cover 3, a sealing cover 4 being disposed on the top cover 3, and the motor 6 being disposed directly above the mixing cylinder 2.

[0023] The striking assembly is located inside the cover 13. The striking assembly includes a fixed rod 14 fixedly connected to the main shaft 7, a spring 15 fixedly connected to the end of the fixed rod 14, a ball 16 fixedly connected to the end of the spring 15, and a stop bar 17 fixedly connected to the top of the top cover 3.

[0024] The intermittent dispensing assembly includes a storage box 12 fixedly connected to the top cover 3. The bottom of the storage box 12 is located below the top cover 3 and is tapered. The top of the storage box 12 is threadedly connected to a cap 19. An incomplete umbrella-shaped conical tooth 18 is fixedly fitted onto the outer wall of the main shaft 7. A baffle 20 is fixedly connected to the inner wall of the storage box 12. A rotating shaft 21 is rotatably connected to the baffle 20 via a bracket. Both ends of the rotating shaft 21 are provided with first umbrella-shaped conical teeth 22. The top of the storage box 12... A central shaft 24 is rotatably connected to the inner side wall of the storage box 12. A second umbrella cone tooth 23 is fixedly sleeved on the central shaft 24. The second umbrella cone tooth 23 is engaged with a first umbrella cone tooth 22 at one end of the rotating shaft 21. The first umbrella cone tooth 22 at the other end of the rotating shaft 21 is engaged with a toothed position on an incomplete umbrella cone tooth 18. A small spiral blade 25 is fixedly wound around the central shaft 24. An opening 26 is opened at the bottom of the storage box 12. The bottom end of the small spiral blade 25 extends to the outside of the storage box 12 through the opening 26.

[0025] The working principle of this premixed powder raw material proportioning and mixing device is as follows: The premixed powder raw material to be mixed is put into the inside of the mixing cylinder 2 through the sealed cover 4, and then the powdered additive is added to the storage box 12 through the screw cap 19. The motor 6 is started, and the output shaft of the motor 6 drives the main shaft 7 to rotate. The main shaft 7 drives multiple plate-type spiral blades 10 to make circular motion through the upper blade 9 and the lower blade 8, mixing the premixed powder raw material inside the mixing cylinder 2. In the above process, the main shaft 7 drives the incomplete umbrella cone tooth 18 to rotate, and drives the rotating shaft 21 to rotate intermittently through the corresponding first umbrella cone tooth 22. The rotating shaft 21 drives the second umbrella cone tooth 23 to rotate intermittently through the corresponding first umbrella cone tooth 22, driving the central shaft 24 to rotate intermittently on the storage box 12. The central shaft 24 drives the additive inside the storage box 12 to fall intermittently from the opening 26 through the small spiral blades 25, slowly pushing the additive into the premixed powder raw material to participate in the mixing.

[0026] When the main shaft 7 rotates, it drives the fixed rod 14, spring 15, and ball 16 to make circular motion. When the spring 15 rotates to contact the stop rod 17, the spring 15 undergoes elastic deformation and bends. When the spring 15 moves to separate from the stop rod 17, the spring 15 releases the deformation elastic force, which drives the ball 16 to strike the outer wall of the storage box 12 to prevent the powdered additives from accumulating on the inner wall of the storage box 12.

[0027] The incomplete umbrella cone tooth 18 contains only a portion of the teeth. When the incomplete umbrella cone tooth 18 rotates, it drives the rotating shaft 21 to rotate through the first umbrella cone tooth 22, causing the rotating shaft 21 to rotate intermittently, which is used to reduce the falling speed of the additives inside the storage box 12.

[0028] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
