[0011] As a further embodiment of the present invention: a connecting block is fixedly connected to both side walls of the symmetrical movable plate; a drive motor is drivenly connected to both side walls of the fixed plate; a screw is drivenly connected to the side wall of the fixed plate; the output end of the drive motor is fixedly connected to the middle of one end of the screw; and the middle of the connecting block is threadedly connected to the screw.

[0012] As a further aspect of the present invention: through slots are provided in the middle of both sides of the movable plate located below, and a movable block is horizontally slidably connected to the inner cavity of the through slot. The inner wall of the through slot and the movable block are elastically connected by a spring. A sorting rod is fixedly connected to the middle of the lower end of the movable block, and an adjusting rod is fixedly connected to the middle of the upper end of the movable block.

[0013] As a further aspect of the present invention: the lower end of the fixed plate is provided with symmetrical guide grooves, the end of the adjusting rod away from the movable block is slidably connected to the inner cavity of the guide groove, the end of the guide groove near the automatic seasoning box is provided with a rectangular groove, and the inner cavity of the rectangular groove away from the automatic seasoning box is provided with a bevel.

[0014] As a further aspect of the present invention: a groove is provided at the connection between the inclined side and the guide groove, an inclined block is slidably connected to the inner cavity of the groove, an inclined surface is provided at the lower end of the inclined block, and the end of the lower end of the inclined block closest to the guide groove is the end closest to the inclined side.

[0015] An automatic food seasoning and sorting method, using the aforementioned automatic food seasoning and sorting device, includes the following steps:

[0016] S1: The servo motor drives two driven gears to rotate sequentially, and then through the transmission cooperation of the rack and driven gears, it drives two sets of symmetrical driven blocks to move closer to the center position of the sorting table in sequence, thereby completing the centering positioning of the dishes on the upper part of the sorting table.

[0017] S2: The screw is driven to rotate by the drive motor, which in turn drives the connecting block and the movable plate to make horizontal reciprocating motion. This causes the sorting rod to move closer to or away from the center of the sorting table. Through the cooperation of the adjusting rod, guide groove and rectangular groove, the dishes are sorted, and dishes of different sizes are moved to different positions. Finally, the dishes are driven away from the sorting table by conveyor belt two or conveyor belt one, thus completing the sorting of the dishes.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Through the transmission and cooperation of servo motors, drive gears, and driven gears and racks, two sets of symmetrical sliders are driven to approach the position of the transmission rod. When the sliders drive the U-shaped plate to move horizontally, the sliding cooperation of the inclined groove and the driven rod drives the driven block to move upward and then horizontally approach the position of the transmission rod, thereby centrally positioning and clamping the dishes located above the sorting table. After the dishes are positioned, the driven block is driven away from the position of the dishes again. After the driven rod returns to the position of the vertical groove, the driven block automatically moves downward. The drive motor and screw drive the movable plate and sorting rod to move horizontally, and through the sliding cooperation of the guide groove and the adjusting rod, the symmetrical sorting rods are kept away from each other and approach the dishes, thereby sorting the dishes according to their size. The sorting rods will push the dishes closer to the second right conveyor belt, or the symmetrical sorting rods will move closer to each other to clamp the dishes, driving the dishes closer to the second left conveyor belt, or they will not move the dishes.

[0032] Please see Figure 1-3 In this embodiment of the invention, an automatic seasoning and sorting device for dishes includes a sorting platform 1. A symmetrical moving groove 9 is provided in the middle of the upper end of the sorting platform 1. A bracket 4 is fixedly connected to the upper end of the sorting platform 1. An automatic seasoning box 6 is fixedly connected to the lower end of the middle of the bracket 4. A fixing plate 5 is fixedly connected to the lower outer wall of the automatic seasoning box 6. A sorting mechanism for sorting dishes is provided on one side of the fixing plate 5. The sorting mechanism includes a symmetrical movable plate 24 and a symmetrical sorting rod 31. When the middle of the movable plate 24 is in contact with the outer wall of the automatic seasoning box 6, the symmetrical sorting rod 31 simultaneously approaches the center position of the automatic seasoning box 6.

[0033] Please see Figure 4-6A U-shaped plate 11 is slidably connected to the inner cavity of the movable slot 9 on the side away from the automatic seasoning box 6. A sliding groove 19 is provided at the bottom of the inner cavity of the movable slot 9. A slider 12 is slidably connected to the inner cavity of the sliding groove 19 near the U-shaped plate 11. The slider 12 is fixedly connected to the U-shaped plate 11. The symmetrical sliding grooves 19 are interconnected to form a "cross groove". A driving mechanism is provided in the middle of the inner cavity of the cross groove. The driving mechanism includes two driven gears 14, one upper and one lower. A transmission is rotatably connected in the middle of the inner cavity of the cross groove. The moving rod 13 and two driven gears 14 are fixedly connected to the outer wall of the transmission rod 13. A rack 16 is fixedly connected to the side of the slider 12 near the transmission rod 13. The end of the rack 16 away from the slider 12 meshes with the driven gear 14. That is, the upper rack 16 meshes with the upper driven gear 14, and the lower rack 16 meshes with the lower driven gear 14. The two racks 16 located in the same horizontal plane are centrally symmetrical about the center of the transmission rod 13.

[0034] Each of the two adjacent slide grooves 19 has a mounting groove 18 on the bottom side near the transmission rod 13. A servo motor 17 is connected to the inner cavity of the mounting groove 18. A drive gear 15 is fixedly connected to the output end of the servo motor 17. The drive gear 15 meshes with the driven gear 14, and the height of the two drive gears 15 corresponds to the height of the two driven gears 14. The two drive gears 15 drive the two driven gears 14 to rotate, and then through the transmission engagement between the driven gears 14 and the rack 16, the symmetrical slider 12 and the U-shaped... Plate 11 is positioned close to the transmission rod 13, thereby centering and clamping the vegetables on the upper end of the sorting table 1. The sorting table 1 is connected by symmetrical conveyor belts 1-2 and 2-3 around its perimeter. The movement direction of conveyor belt 2-3 is perpendicular to the movement direction of conveyor belt 1-2. The vegetables to be sorted are transported to the upper end of the sorting table 1 by conveyor belt 1-2 on one side, and then sorted by the sorting mechanism to determine the subsequent movement direction of the vegetables. In the following text, the two conveyor belts 2-3 are referred to as the left conveyor belt 2-3 and the right conveyor belt 2-3, respectively.

[0035] A driven block 10 is vertically slidably connected to the upper middle part of the U-shaped plate 11. The lower end of the driven block 10 is elastically connected to the bottom of the inner cavity of the U-shaped plate 11 by a spring. Inclined grooves 22 are provided in the middle of both sides of the U-shaped plate 11. A driven rod 23 is fixedly connected to the middle of both sides of the driven block 10. The middle of the outer wall of the driven rod 23 slides in fit with the inner cavity of the inclined groove 22. A symmetrical vertical groove 20 is provided on the side of the inner cavity of the moving groove 9 near the U-shaped plate 11. The end of the driven rod 23 away from the driven block 10 passes through the inner cavity of the inclined groove 22 and slides in fit with the vertical groove 20. With the U-shaped plate 11 moving the inclined groove 22 toward the position of the transmission rod 13, the inclined groove 22 and the driven rod 23 move relative to each other. The end of the driven rod 23 away from the driven block 10 is located in the vertical groove 20. Therefore, the driven rod 23 cannot move horizontally with the U-shaped plate 11. Under the guidance of the driven rod 23, the driven rod 23 will move vertically upward in the inner cavity of the vertical groove 20, thereby driving the driven block 10 to move vertically upward, so that the upper end surface of the driven block 10 after moving upward is higher than the upper end surface of the sorting table 1.

[0036] A horizontal groove 21 is provided on the upper end of the vertical groove 20 near the transmission rod 13. After the driven rod 23 moves to the top of the inner cavity of the vertical groove 20, the end of the driven rod 23 is located at the connection between the vertical groove 20 and the horizontal groove 21. As the U-shaped plate 11 continues to move towards the position of the transmission rod 13, the driven rod 23 will move in the inner cavity of the horizontal groove 21, so that the driven block 10 maintains its position after moving upwards and is horizontally close to the transmission rod 13. This allows for the centralized positioning and support of the dishes on the upper end of the sorting table 1. That is, after the conveyor belt 2 on one side transports the dishes to the upper surface of the sorting table 1, the servo motor 17 drives the two sets of symmetrical sliders 12 sequentially. The food is positioned close to the transmission rod 13, and then the two sets of symmetrical driven blocks 10 are moved upward and horizontally close to the transmission rod 13. The driven blocks 10 then center the food, so that the food is located in the middle of the upper part of the sorting table 1. At this time, the food is directly below the automatic seasoning box 6, and the food can be automatically seasoned by the automatic seasoning box 6. The automatic seasoning box 6 consists of multiple seasoning containers, which contain various seasonings. The automatic seasoning box 6 is a commonly used technology in the prior art. It can automatically control the addition of seasonings in the box. The motor drives the compartments to rotate and automatically add water, oil, salt, soy sauce, etc. in steps. Some parts support pipeline cleaning to avoid cross-contamination of flavors.

[0037] Please see Figure 7-8A connecting block 25 is fixedly connected to both side walls of the symmetrical movable plate 24. A drive motor 27 is drivenly connected to both side walls of the fixed plate 5, and a screw 26 is drivenly connected to the side wall of the fixed plate 5. The output end of the drive motor 27 is fixedly connected to the middle of one end of the screw 26, and the middle of the connecting block 25 is threadedly connected to the screw 26. Therefore, when the drive motor 27 drives the screw 26 to rotate, it will cause the connecting block 25 to move horizontally closer to or away from the position of the automatic seasoning box 6. This, in turn, causes the movable plate 24 and the sorting rod 31 to move synchronously closer to or away from the automatic seasoning box 6 via the connecting block 25. At the location of the seasoning box 6, a through groove 28 is provided on both sides of the movable plate 24 below. A movable block 29 is horizontally slidably connected to the inner cavity of the through groove 28. The inner wall of the through groove 28 and the movable block 29 are elastically connected by a spring. The spring is used to drive the movable block 29 to move toward the center of the movable plate 24. A sorting rod 31 is fixedly connected to the lower center of the movable block 29, and an adjusting rod 30 is fixedly connected to the upper center of the movable block 29. When the connecting block 25 drives the movable plate 24 to move horizontally, the sorting rod 31 will also move horizontally synchronously with the movable plate 24.

[0038] Please see Figure 9-11 The lower end of the fixed plate 5 is provided with symmetrical guide grooves 32. The end of the adjusting rod 30 away from the movable block 29 is slidably connected to the inner cavity of the guide groove 32. The end of the guide groove 32 near the automatic seasoning box 6 is provided with a rectangular groove 33. When the movable plate 24 drives the movable block 29 and the adjusting rod 30 to move towards the position of the automatic seasoning box 6, the adjusting rod 30 will move horizontally in the inner cavity of the guide groove 32 until the adjusting rod 30 moves to the connection point of the guide groove 32 and the rectangular groove 33. At this time, under the action of the spring, the movable block 29 drives the adjusting rod 30 and the sorting rod 31 to move towards the center position of the movable plate 24. The middle part of the movable plate 24 is arc-shaped. When the inner cavity of the movable plate 24 is in contact with the outer wall of the automatic seasoning box 6, the center position of the sorting rod 31 and the center position of the automatic seasoning box 6 are in the same vertical plane. At this time, the adjusting rod 30 is also located at the connection point of the guide groove 32 and the rectangular groove 33.

[0039] During the process of the symmetrical sorting rods 31 synchronously approaching the center of the automatic seasoning box 6, when the length of the dish is greater than the distance between the symmetrical guide grooves 32, the sorting rods 31 will push the dish toward the position of the right conveyor belt 3. When the length of the dish is greater than the distance between the symmetrical rectangular grooves 33 and less than the distance between the symmetrical guide grooves 32, when the symmetrical sorting rods 31 approach the center of the movable plate 24, the symmetrical sorting rods 31 will clamp the dish. During the process of the movable plate 24 resetting, the dish will move synchronously with the sorting rods 31 toward the position of the left conveyor belt 3.

[0040] When the length of the dish is less than the distance between the symmetrical rectangular slots 33, even if the sorting rod 31 moves to the position near the center of the movable plate 24 inside the rectangular slot 33 under the action of the elastic force, the symmetrical sorting rod 31 will not come into contact with the dish. At this time, the dish will still be located in the middle of the upper end of the sorting table 1 and will not move to the left or right. The middle of the upper end of the sorting table 1 is connected to two sets of symmetrical conveyor belts 8. The movement direction of the conveyor belts 8 is the same as that of the conveyor belts 2. The conveyor belts 2 and 8 on one side drive the dish to move towards the center of the sorting table 1. The conveyor belts 2 and 8 on the other side drive the dish away from the center of the sorting table 1. The upper end of the sorting table 1 is connected to symmetrical conveyor belts 7 near the side of the second conveyor belt 3. The second conveyor belts 7 and 3 drive the dish away from the center of the sorting table 1, which facilitates the sorting of the dish.

[0041] Please see Figure 11 When the symmetrical sorting rod 31 moves the food towards the left conveyor belt 3, the food will move from the center of the upper end of the sorting table 1 to the conveyor belt 7 near the left conveyor belt 3. The inner cavity of the rectangular groove 33 has a bevel 34 on the side away from the automatic seasoning box 6. When the adjusting rod 30 contacts the bevel 34, the symmetrical sorting rod 31, guided by the bevel 34, will continuously move away from the food's location, eventually separating from the food, so that the food only contacts the conveyor belt 7. At this point, the conveyor belt 7 can drive the food to the left conveyor belt 3. A groove 36 is provided at the connection between the bevel 34 and the guide groove 32. The inner cavity of the groove 36 slides... A kinetic block 35 is connected to the upper end of the groove 36 via a spring. The lower end of the kinetic block 35 has a sloping surface. The end of the lower end of the kinetic block 35 closest to the guide groove 32 is the end closest to the inclined side 34. Therefore, the adjusting rod 30 will be guided by the inclined side 34 to approach the position of the kinetic block 35 and contact the side of the kinetic block 35 closest to the inclined side 34, squeezing the kinetic block 35 into the inner cavity of the groove 36, and then returning to the inner cavity of the guide groove 32. After the adjusting rod 30 passes the kinetic block 35 and enters the guide groove 32, it will not return to the rectangular groove 33 under the action of the spring force, and finally complete the reset of the sorting rod 31, thus facilitating the next sorting of the dishes.

[0042] Therefore, when sorting the dishes, dishes larger than the distance between the symmetrical guide grooves 32 will be pushed onto the conveyor belt 7 of the conveyor belt 3 on the right side as the sorting rod 31 moves horizontally toward the automatic seasoning box 6. Under the action of the conveyor belt 7, the dishes will be driven to move onto the conveyor belt 3 on the right side. Dishes smaller than the distance between the symmetrical rectangular grooves 33 will be held tightly and moved to the conveyor belt 2 on the other side under the action of the conveyor belt 8. The symmetrical sorting rod 31 will be driven to move horizontally back and forth by the movable plate 24, which can quickly complete the sorting of dishes. The conveyor belt 8 is set so that when the dishes just enter the upper part of the sorting table 1, the dishes can be driven to move toward the center of the sorting table 1 by the conveyor belt 8, and then the driven block 10 will be used to centrally position the dishes, thereby improving the positioning efficiency of the dishes. After positioning, the dishes can be prepared.

[0043] An automated method for preparing and sorting ingredients for dishes includes the following steps:

[0044] S1: The servo motor 17 drives two driven gears 14 to rotate sequentially, and then through the transmission cooperation of the rack 16 and the driven gears 14, drives two sets of symmetrical driven blocks 10 to move closer to the center position of the sorting table 1 in sequence, thereby completing the centering positioning of the dishes on the upper end of the sorting table 1.

[0045] S2: The screw 26 is driven to rotate by the drive motor 27, which in turn drives the connecting block 25 and the movable plate 24 to perform horizontal reciprocating motion, causing the sorting rod 31 to move closer to or away from the center position of the sorting table 1. Through the cooperation of the adjusting rod 30, the guide groove 32 and the rectangular groove 33, the dishes are sorted, and dishes of different sizes are moved to different positions. Finally, the dishes are driven away from the sorting table 1 by the second conveyor belt 7 or the first conveyor belt 8, thus completing the sorting of the dishes.
