[0002] In the food processing industry, material pretreatment and mixing are critical steps in ensuring product quality. Traditional food mixing processes often rely on single-use mixing equipment, which is unable to pre-screen and grade materials. Directly mixing materials of different particle sizes can easily lead to uneven mixing, agglomeration, and stratification, affecting the taste and texture of the food. While some equipment is equipped with screening devices, these devices have low screening efficiency, are prone to clogging, and the screening and mixing functions are independent of each other, requiring manual material transfer. This not only increases labor intensity but also may introduce secondary contamination and reduce production efficiency.

It cannot adapt to mixing containers of different capacities and depths, and has poor versatility. In addition, the stirring method is single, mostly relying on single-axis or double-axis stirring, which makes it difficult to achieve multi-dimensional flipping and shearing of materials.

[0025] The following is combined with Figure 1-5 The present invention is described in further detail.

[0026] The embodiment of the present invention discloses a pre-mixing mechanism for food processing. Figure 1-Figure 3 , including a screening box 1 and a mixing seat 4, a filter screen 8 is fixedly provided in the screening box 1, a vibration motor 6 is installed on the outer wall of the screening box 1, a support frame 2 is provided on the outer wall of the screening box 1 for support, and rocker arms 7 are symmetrically provided on both sides of the inner wall of the support frame 2, and both ends of the rocker arms 7 are connected to a rotating shaft 12, and the two rotating shafts 12 are rotatably connected to the rocker arms 7 and the outer wall of the screening box 1 respectively, and guide buckets 1 3 and guide buckets 2 11 are staggered on the outer walls of both sides of the screening box 1, and one end of the guide bucket 2 11 extends to the mixing seat 4. The vibration motor 6 drives the screening box 1 and the filter screen 8 to vibrate at a high frequency. Combined with the swing design of the screening box 1 around the rotating shaft 12, the material is fully tumbled on the screen, greatly improving the screening efficiency; the filter screen 8 accurately separates materials of different particle sizes, large pieces of crushed materials are discharged through the guide bucket 1 3, and fine materials are transported through the guide bucket 2 11, realizing automatic grading and avoiding the inefficiency and errors of manual screening.

[0027] In the present application, a mixing chamber 13 is defined within the mixing base 4, and a discharge pipe 14 is provided at the bottom end of the outer wall of the mixing base 4, with a regulating valve mounted on the discharge pipe 14. A mounting bracket 5 is fixed to the side wall of the mixing base 4, which includes a screw assembly mounted within the mounting bracket 5. A motor 9 is mounted on the mounting bracket 5. The screw assembly includes a screw 27 mounted within the mounting bracket 5, and a screw slider 28 adapted to the screw 27. A support arm 10 is connected to the screw assembly, and a fixed block is connected between the screw slider 28 and the support arm 10. A chute 15 adapted to the fixed block is defined on the inner wall of the mounting bracket 5. The motor 9 drives the screw 27 to rotate, and the screw slider 28 slides along the chute 15, flexibly adjusting the height of the support arm 10 so that the mixing assembly can adapt to mixing chambers 13 of different capacities and heights to meet diverse production needs. The guide structure of the mounting bracket 5 and the screw assembly ensures stable lifting and lowering of the mixing assembly, preventing shaking from affecting the mixing effect.

[0028] like Figure 4 As shown, a mixing assembly is mounted at the bottom of support arm 10. The mixing assembly comprises a gear unit, an extension arm 17 mounted on the gear unit, a mixing rod 18, an extension arm 25, and a mixing rod 26. Motor 2 16 is fixedly mounted at the bottom of support arm 10. The output end of motor 16 is connected to a turntable. One end of extension arm 17 is fixed to the outer wall of the turntable, and mixing rod 18 is rotatably connected to the inner wall of extension arm 17, creating a multi-dimensional stirring effect, turning and mixing the materials in mixing chamber 13.

[0029] like Figure 5 As shown, the gear portion includes a bevel gear 19 fixed to the bottom of the turntable, a bevel gear 22 distributed on both sides of the bevel gear 19, and a bevel gear 3 24 located at the bottom of the bevel gear 19 and symmetrically arranged therewith. A connecting shaft 20 is rotatably connected to the middle of the inner wall of the bevel gear 19, and a support shaft 21 is symmetrically fixed to the side wall of the connecting shaft 20. The support shaft 21 is rotatably connected to the bevel gear 2 22. A rotating shaft 23 is rotatably installed on the bottom end of the connecting shaft 20. The rotating shaft 23 is fixed to the outer wall of the bevel gear 3 24. One end of the rotating shaft 23 extends to the bottom of the bevel gear 3 24 and is connected to the outer wall of the extension arm 2 25. Motor 2 16 drives the turntable to rotate, and extension arm 17 drives mixing rod 18 to revolve. At the same time, the meshing transmission of bevel gear 19, bevel gear 22, and bevel gear 3 24 enables mixing rod 18 and mixing rod 2 26 to rotate and rotate in the opposite direction, forming a compound motion trajectory of "revolution + rotation", shearing, flipping, and convection of the material, eliminating mixing dead corners, and ensuring mixing uniformity.

[0030] The implementation principle of a pre-mixing mechanism for food processing according to an embodiment of the present invention is as follows:

[0031] During use, the material to be processed is poured into the screening box 1, and the vibration motor 6 is started. The vibration force generated by the vibration motor 6 is transmitted through the screening box 1 to the internal filter 8, causing the material to vibrate and screen on the filter 8. Large pieces of material with a particle size larger than the filter 8 are discharged outward through the guide bucket 1 3, while material with a particle size smaller than the aperture of the filter 8 passes through the filter 8 and falls to the bottom of the screening box 1. At the same time, the screening box 1 is hinged to the rocker 7 through the rotating shafts 12 on both sides. Under the action of the vibration motor 6, the screening box 1 can swing slightly around the rotating shafts 12. The rotating shafts 12 at both ends of the rocker 7 ensure the stability of the screening box 1 during swinging, thereby improving screening efficiency. The fine material after screening is transported to the mixing chamber 13 of the mixing seat 4 through the guide bucket 2 11.

[0032] During the mixing phase, Motor 1 (9) on mounting bracket 5 is first activated. This drives screw 27 in the screw assembly to rotate, and screw slider 28, which is adapted to screw 27, slides axially along screw 27. Screw slider 28, guided by the fixed block within slot 15, drives support arm 10 up and down, adjusting the mixing assembly to the appropriate height within mixing chamber 13. Subsequently, Motor 2 (16) is activated. The output of Motor 2 (16) drives the turntable to rotate, and extension arm 17, fixed to the outer wall of the turntable, rotates accordingly, causing mixing rod 18 to perform a circular motion within mixing chamber 13. At the same time, the bevel gear 19 at the bottom of the turntable rotates synchronously, and transmission is achieved through the meshing bevel gear 2 22 and the bevel gear 3 24: the bevel gear 19 rotates and meshes with the bevel gear 2 22 on both sides, so that the bevel gear 2 22 rotates outside the support shaft 21, and the bevel gear 3 24 at the bottom of the bevel gear 1 19 is connected to the extension arm 2 25 through the rotating shaft 23, meshes with the bevel gear 2 22 and rotates synchronously in the opposite direction, thereby driving the mixing rod 2 26 to move.

[0033] Driven by the gear unit, mixing rods 18 and 26 create a multi-dimensional stirring effect, turning and mixing the material within mixing chamber 13. Once mixing is complete, the regulating valve on discharge pipe 14 is opened to discharge the material from mixing chamber 13. By combining the vibratory classification of screening box 1 with the multi-axis coordinated stirring of the mixing assembly, this mechanism enables precise pretreatment and uniform mixing of materials of varying particle sizes, meeting the diverse needs of food processing.
