The output end of the first motor 21 is coaxially fixedly connected to the drive shaft 22, and a worm 23 is coaxially fixedly connected to the drive shaft 22.

[0033] The spreading mechanism 4 also includes a second motor 24 fixedly installed in the sorting platform 1. The model of the second motor 24 is preferably Y80M1-2. The output end of the second motor 24 is coaxially fixedly connected to a threaded rod 25. One end of the sliding plate 7 is fixedly connected to a driving block 26. The threaded rod 25 passes through the driving block 26 and is threadedly connected to the driving block 26. A guide groove 27 is provided in the sorting platform 1, which is horizontally slidably connected to the side wall of the driving block 26. A control component 28 for synchronously controlling the operating status of the conveyor belt 5 is provided on the sorting platform 1.

[0034] The control component 28 includes two groups of drive rollers 29 rotatably connected to the inner wall of the sorting platform 1. The inner wall of the conveyor belt 5 is transmission-connected to the outer walls of the two groups of drive rollers 29. A support plate 30 is fixedly connected to the sorting platform 1. The upper and lower sides of the support plate 30 are slidingly connected to the inner wall of the conveyor belt 5. Both ends of the drive roller 29 close to the drive block 26 are coaxially fixedly connected to a drive disk 31. The drive disk 31 is provided with a drive component 32 for controlling the rotation state of the drive roller 29.

[0035] The driving member 32 includes multiple groups of ratchets 34 rotatably connected to the driving disk 31 through a clockwork shaft. Two groups of sliding rods 35 are fixedly connected to the bottom of the sliding plate 7. Multiple groups of first beveled tooth blocks 36 are evenly fixedly connected to the sliding rods 35. The inclined surfaces of the first beveled tooth blocks 36 face the side of the driving block 26. The first beveled tooth blocks 36 are used to push the ratchets 34 to rotate in one direction. A second beveled tooth block 37 for unidirectionally limiting the rotation direction of the ratchets 34 is fixedly connected inside the sorting table 1.

[0036] Working principle: The low-fat bread ingredients to be sorted are placed into the feed hopper 9. According to the amount of material to be sorted each time, the operating state of the electric telescopic rod 15 is adjusted so that the pushing plate 6 drives the adjusting frame 13 to be raised and lowered 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 only fall between the second conveying frame 12 and the adjusting frame 13 for transportation. During the lifting process of the pushing plate 6, the first motor 21 is synchronously controlled to rotate, driving the drive shaft 22 to rotate the worm 23, and the worm 23 drives the worm gear 18 to enable the rotating rod 16 to drive the rotating plate 17 to rotate, ensuring that the bottom end of the rotating plate 17 can always fit in place with the top surface of the conveyor belt 5, thereby preventing the raw materials in the second conveying frame 12 from leaking out from the bottom of the rotating plate 17.

[0037] During the lifting and adjusting process, the push plate 6 will drive the guide plate 14 to lift and lower synchronously. The guide plate 14 drives the lifting frame 10 to lift and slide on the inner wall of the feed hopper 9, so that the gap between the bottom of the feed hopper 9 and the push plate 6 is blocked by the lifting plate. The raw materials in the feed hopper 9 can only enter the first conveying frame 11 and the second conveying frame 12 for storage through the lifting frame 10. In the subsequent horizontal sliding process of the push plate 6, the horizontal sliding of the guide plate 14 will not drive the lifting frame 10 to move, thereby avoiding overflow of raw materials. By changing the height of the push plate 6, the overall capacity of the first conveying frame 11, the second conveying frame 12 and the adjustment frame 13 changes, thereby achieving precise control and adjustment of the feeding amount each time.

[0038] During transportation, the second motor 24 is started to drive the threaded rod 25 to rotate, and the threaded rod 25 drives the driving block 26 to make the sliding plate 7 slide on the upper side of the sorting platform 1, and the bottom surface of the sliding plate 7 slides in contact with the top surface of the conveyor belt 5, and the raw materials stored inside are pushed onto the conveyor belt 5 through the first conveying frame 11 and the second conveying frame 12 and the rotating plate 17. In this process, the sliding plate 7 will drive the sliding rod 35 to make the first bevel gear block 36 move horizontally, and the vertical side of the first bevel gear block 36 will push the tip of the ratchet 34 to rotate, thereby driving the driving roller 29 to rotate synchronously, and the driving roller 29 drives the conveyor belt 5 to transport, 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 to prevent the raw materials in the hopper 9 from overflowing from the bottom during transportation.

[0039] When the sliding plate 7 pushes the raw materials to the side position of the conveyor belt 5 close to the collecting box 38, that is, when the stop block 19 reaches the position of the first control key 39, the second motor 24 is triggered to rotate in the opposite direction, and the control threaded rod 25 rotates in the opposite direction to drive the sliding plate 7 to slide in the opposite direction, and at the same time drives the pushing plate 6 to slide in the opposite direction. At this time, the sliding rod 35 drives the first bevel gear block 36 to move in the opposite direction, and the inclined surface of the first bevel gear block 36 will slide in contact with the arc surface of the ratchet 34, pushing the ratchet 34 to swing toward the side of the driving disk 31, and is subject to the resistance of the second bevel gear block 37 to the tip of the ratchet 34, so that the driving disk 31 will not rotate in the opposite direction driven by the first bevel gear block 36, thereby ensuring that the conveyor belt 5 is in a stationary state at this time. At the same time, according to the thickness of paving required, the operating state of the first motor 21 is controlled, so that the worm 23 drives the rotating rod 16 and the rotating plate 17 to rotate, and the bottom end of the rotating plate 17 is tilted and lifted toward the side of the collecting box 38, thereby changing the gap between the bottom end of the rotating plate 17 and the conveyor belt 5. After the gap size is adjusted to an appropriate value, the operation of the first motor 21 is stopped. Thereafter, during the process of the sliding plate 7 and the pushing plate 6 sliding in opposite directions, the raw materials in the first conveying frame 11 and the second conveying frame 12 can be spread onto the conveyor belt 5 through the bottom end of the rotating plate 17, thereby realizing the function of uniform paving. At the same time, the raw material conveying amount, paving thickness and area and other values ​​can be flexibly adjusted according to the size and quantity of the raw materials.

[0040] When the baffle reaches the position of the second control key 40, it means that the bottom end of the lifting frame 10 is connected to the first conveying frame 11. At this time, the material in the second conveying frame 12 is also spread. The first motor 21 is controlled to rotate in the opposite direction, so that the rotating plate 17 swings downward to a position that is in contact with the top surface of the conveyor belt 5. The blocking 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 material 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 material and the rotating plate 17. When the driving block 26 reaches the position of one end of the threaded rod 25, the second motor 24 stops running. At this time, the bottom end of the lifting frame 10 is just connected to the first conveying frame 11, and the sliding plate 7 and the pushing plate 6 are reset. Repeat the above operation to carry out the next feeding and paving operation, thereby improving the efficiency of subsequent manual sorting.

[0041] It is worth noting that: when the sliding plate 7 and the conveyor belt 5 move synchronously toward the side of the collecting box 38, the bottom of the rotating plate 17 is in contact with the top surface of the conveyor belt 5, and the conveyor belt 5 can transfer the sorted raw materials above to the collecting box 38 for collection, while foreign matter in the raw materials after paving is manually sorted out. The bottom surface of the side plate 2 is in contact with the top surface of the conveyor belt 5, which is used to block the separation generated between the conveyor belt 5 and the sorting platform 1.
