The following connections can be made via pins, hinges, or other structures: the rotating shaft 4 and the positive pawl; the rotating shaft 4 and the negative pawl; the driven link 652 and the rotating support 62; the sliding rod 65 and the driving link 651; the driving link 651 and the driven link 652; the driving slider 74 and the adjusting link 741; the lifting component 73 and the adjusting link 741; the driven base plate 751 and the lever 76; the driving base plate 742 and the extension link 743; and the lever 76 and the extension link 743. The reverse bushing 48 and the sliding bushing 46; the baffle plate 57 and the storage box 5; the end plate and the rotating support 62; the driving slider 74 and the side wall of the clearance groove; and the driven slider 75 and the side wall of the clearance groove. All connections can be made via sliding groove structures.

[0039] In the implementation of this invention: The mixing drive 49 is activated, causing the rotating shaft 4 to rotate forward. At this time, the forward ratchet 421 engages with the forward pawl, while the reverse ratchet 481 does not engage with the reverse pawl. The forward rotating sleeve 41 drives the bent mounting plate 43 and the support shaft 6 to rotate synchronously to below one of the storage bins 5, causing the sector gear 45 to mesh with one of the missing-tooth gears 55. Then, the rotating shaft 4 rotates in reverse. The forward ratchet 421 does not engage with the forward pawl, while the reverse ratchet 481 engages with the reverse pawl. The reverse rotating sleeve 48 drives the sector gear 45 to rotate. When the sector gear 45 engages with the missing-tooth gear 55... When the gear 55 meshes, it can drive the rotating assembly 54 to rotate, and the baffle plate 57 disengages from the discharge chute 52. The material in the storage box 5 falls into the holding box 63 through the discharge chute 52. When the sector gear 45 does not mesh with the toothed gear 55, the baffle plate 57 automatically resets under the action of the torsion spring, blocking the discharge chute 52. Since the area of ​​each discharge chute 52 is different, during weighing, according to the difference between the current weighing value and the preset value, the discharge chute 52 with different areas is selected for feeding (a large chute is used for a large difference, and a small chute is used for a small difference), thereby achieving accurate weighing.

[0040] The material falls into the container 63, and the weighing element 611 weighs the material. After the appropriate material weight is measured, the rotating shaft 4 rotates forward, causing the rotating shaft sleeve 41 to rotate until the sector gear 45 meshes with the driven gear 71. Then the rotating shaft 4 rotates in reverse, and the sector gear 45 drives the driven shaft 7 to rotate, causing the lifting component 73 to rise. Under the action of the adjusting linkage 741, the active slider 74 moves towards the driven shaft 7. During this process, under the action of the extension linkage 743, the lever 76 rotates to abut against the translation component 66. The through groove on the lever 76 corresponds to the spring extension rod 68. Then the active slider 74 continues to move, thereby compressing the spring. The translation component 66 moves away from the rotating shaft 4, and the pushing component 671 abuts against the sliding rod 65, causing the sliding rod 65 to move synchronously. Under the action of the active connecting rod 651, the driven connecting rod 652 lifts the side extension plate 641 upward, thereby causing the material container 63 to move away from the weighing element 611. During this period, the guide post is always located in the straight section of the guide groove 612. The translation component 66 continues to move, and the key block 621 engages with the keyway on the inner bushing 661. At this time, the guide post enters the spiral section of the guide groove 612, and the inner bushing 661 drives the rotating support component 62 and the material container 63 to rotate 92°, pouring the material in the material container 63 into the mixing box 3.

[0041] After weighing multiple materials, the rotating shaft 4 rotates forward, causing the sector gear 45 to rotate until it neither meshes with the toothed gear 55 nor with the driven gear 71. Then the rotating shaft 4 rotates in reverse, and the stirring rod 401 premixes the materials.

[0042] This invention provides a rotary food production apparatus, which has the following advantages: 1. By setting up an extrusion mechanism, it is possible to achieve twin-screw conveying of materials, ensuring good production efficiency and product quality, and improving the stability and reliability of the equipment. It is also possible to achieve the production of different products by switching molds, thus expanding the applicability of the device.

[0043] 2. By setting up a mixing mechanism, the material weighing and pre-mixing can be completed automatically, improving the initial uniformity of the material, and the material can be accurately weighed, improving the accuracy of the material ratio, thereby improving product quality.

[0044] In summary, the beneficial effects of this invention are: it can produce different foods by switching molds, automatically weigh and premix materials, and accurately weigh materials to ensure good product quality and production efficiency.

[0045] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
