The output end of the second motor 24 is coaxially fixedly connected with a threaded rod 25. One end of the sliding plate 7 is fixedly connected with a driving block 26. The threaded rod 25 penetrates through the driving block 26 and is threadedly connected with the driving block 26. A guiding groove 27 for slidably connecting with the side wall of the driving block 26 in the horizontal direction is formed in the sorting table 1. A control member 28 for synchronously controlling the operating state of the conveyor belt 5 is arranged on the sorting table 1.

[0024] The control member 28 includes two driving rollers 29 rotatably connected to the inner wall of the sorting table 1. The inner wall of the conveyor belt 5 is in driving connection with the outer walls of the two driving rollers 29. A supporting plate 30 is fixedly connected in the sorting table 1. The upper and lower sides of the supporting plate 30 are both slidably connected with the inner wall of the conveyor belt 5. Driving disks 31 are coaxially fixedly connected to both ends of the driving roller 29 close to the driving block 26. A driving member 32 for controlling the rotation state of the driving roller 29 is arranged on the driving disk 31.

[0025] The driving member 32 includes multiple groups of ratchet teeth 34 rotatably connected to the driving disc 31 through a winding rotating shaft. Two sliding rods 35 are fixedly connected to the bottom of the sliding plate 7. Multiple groups of first bevel gear blocks 36 are fixedly connected to the sliding rods 35 at equal intervals. The inclined surface of the first bevel gear block 36 faces the side of the driving block 26. The first bevel gear block 36 is used to unidirectionally push the ratchet teeth 34 to rotate. A second bevel gear block 37 for unidirectionally limiting the rotation direction of the ratchet teeth 34 is fixedly connected inside the sorting table 1.

[0026] Working principle: Put the raw materials of low-fat bread to be sorted into the feeding hopper 9. According to the feeding amount required for each sorting, adjust the operating state of the electric telescopic rod 15, so that the pushing plate 6 drives the adjusting frame 13 to perform lifting adjustment in the second conveying frame 12. The adjusting frame 13 can block three sides of the second conveying frame 12, while the rotating plate 17 can block the fourth side of the second conveying frame 12, ensuring that the raw materials can finally only fall on the position between the second conveying frame 12 and the adjusting frame 13 for conveying. During the lifting process of the pushing plate 6, synchronously control the rotation of the first motor 21, drive the drive shaft 22 to make the worm 23 rotate, and the worm 23 drives the worm wheel 18 to make the rotating rod 16 drive the rotating plate 17 to rotate, ensuring that the bottom end of the rotating plate 17 can always be in contact with the top surface of the conveyor belt 5, preventing the raw materials in the second conveying frame 12 from leaking out from the bottom of the rotating plate 17.

[0027] During the lifting adjustment process of the pushing plate 6, it will drive the guide plate 14 to lift synchronously. The guide plate 14 drives the lifting frame 10 to slide up and down on the inner wall of the feeding hopper 9, so that the gap between the bottom of the feeding hopper 9 and the pushing plate 6 is blocked by the lifting plate. The raw materials in the feeding hopper 9 can only enter the first conveying frame 11 and the second conveying frame 12 for storage through the lifting frame 10. During the subsequent horizontal sliding process of the pushing plate 6, the horizontal sliding of the guide plate 14 will not drive the lifting frame 10 to move, avoiding the overflow of raw materials. By changing the height of the pushing plate 6, the overall capacity of the first conveying frame 11, the second conveying frame 12, and the adjusting frame 13 changes, realizing the precise control and adjustment of the feeding amount each time.

[0028] When transporting, start the second motor 24 to drive the threaded rod 25 to rotate. The threaded rod 25 drives the driving block 26 to make the sliding plate 7 slide on the upper side of the sorting table 1. The bottom surface of the sliding plate 7 fits and slides with the top surface of the conveyor belt 5. Through the first conveying frame 11, the second conveying frame 12 and the rotating plate 17, the raw materials stored inside are pushed onto the conveyor belt 5. During this process, the sliding plate 7 drives the sliding rod 35 to make the first bevel gear block 36 move horizontally. The vertical side of the first bevel gear block 36 will push the tip of the ratchet tooth 34 to rotate, thereby driving the driving roller 29 to rotate synchronously. The driving roller 29 drives the conveyor belt 5 to convey, ensuring the synchronous movement between the conveyor belt 5 and the sliding plate 7. At the same time, the top surface of the pushing plate 6 can effectively block the bottom surface of the lifting frame 10, preventing the raw materials in the feeding hopper 9 from overflowing from the bottom during transportation.

[0029] When the sliding plate 7 pushes the raw materials to the side of the conveyor belt 5 close to the collection box 38, that is, when the stop block 19 reaches the position of the first control key 39, it triggers the second motor 24 to rotate in the reverse direction. Control the threaded rod 25 to rotate in the reverse direction to drive the sliding plate 7 to slide in the reverse direction, and at the same time drive the pushing plate 6 to slide in the reverse direction together. At this time, the sliding rod 35 drives the first bevel gear block 36 to move in the reverse direction. The inclined surface of the first bevel gear block 36 will fit and slide with the arc surface side of the ratchet tooth 34, pushing the ratchet tooth 34 to swing towards the driving disc 31 side, and being resisted by the second bevel gear block 37 against the tip of the ratchet tooth 34, making the driving disc 31 not rotate in the reverse direction driven by the first bevel gear block 36, ensuring that the conveyor belt 5 is in a stationary state at this time. At the same time, according to the required paving thickness, control the operating state of the first motor 21, so that the worm 23 drives the rotating rod 16 and the rotating plate 17 to rotate. The bottom end of the rotating plate 17 tilts and lifts towards the collection box 38 side, changing the gap size between the bottom end of the rotating plate 17 and the conveyor belt 5. After the gap size is adjusted to an appropriate value, stop the operation of the first motor 21. Thereafter, during the reverse sliding process of the sliding plate 7 and the pushing plate 6, the raw materials in the first conveying frame 11 and the second conveying frame 12 can be paved onto the conveyor belt 5 through the bottom end of the rotating plate 17, realizing the function of uniform paving, and at the same time, the raw material conveying amount, paving thickness, area and other values can be flexibly adjusted according to the raw material size and quantity.

[0030] When the baffle reaches the position of the second control key 40, it indicates that the bottom end of the lifting frame 10 is in communication with the first conveying frame 11. At this time, the raw materials in the second conveying frame 12 are also spread out. Control the first motor 21 to rotate reversely, so that the rotating plate 17 swings downward to a position where it fits against the top surface of the conveyor belt 5, and then the sealing of the sides of the first conveying frame 11 and the second conveying frame 12 can be completed, and the subsequent quantitative input operation of the raw materials can be carried out. Due to the support of the support plate 30, the top surface of the conveyor belt 5 is always in a relatively horizontal state and will not be bent by the raw materials and the rotating plate 17. After the driving block 26 reaches the position at one end of the threaded rod 25, the second motor 24 stops running. At this time, the bottom end of the lifting frame 10 just communicates with the first conveying frame 11, and the sliding plate 7 and the pushing plate 6 are reset. Repeating the above operations can perform the next feeding and spreading operations, improving the subsequent manual sorting efficiency.

[0031] It should be noted that when the sliding plate 7 and the conveyor belt 5 run synchronously towards the side of the collection box 38, at this time, the bottom of the rotating plate 17 fits against the top surface of the conveyor belt 5. The conveyor belt 5 can convey the sorted raw materials above into the collection box 38 for collection, and the foreign objects in the spread raw materials are sorted out manually. The bottom surface of the side plate 2 fits against the top surface of the conveyor belt 5 to block the analysis generated between the conveyor belt 5 and the sorting table 1.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
