The two rotating shafts 102 and multiple rotating tubes 103 located on the same side are connected through a transmission component. The sorting and identification camera 2 is installed on the Z-shaped plate 10, and a lifting component for height adjustment used by the sorting and identification camera 2 during the identification process is arranged between the Z-shaped plate 10 and the side plate 101.

[0027] The supporting assembly includes a plurality of slide grooves 301 arranged in an annular array on the rollers 105, and each slide groove 301 is slidably connected with a support plate 302 through a sliding assembly. Each support plate 302 has an arc-shaped surface at one end thereof that abuts against the inner side of the conveyor belt 106. The interior of the rollers 105 is provided with a connecting assembly for connecting the rollers 105. During the conveying process of the conveyor, along with the rotation of each roller 105, one end of the support plate 302 arranged in an annular array on both sides of the rollers 105 lifts and supports the conveyor belt 106 during the conveying process, so that the conveyor belt 106 can be transported more stably.

[0028] The sliding assembly includes a T-slot 401 opened on the slide groove 301, a T-block 402 is slidably connected to the T-slot 401, and the T-block 402 is fixed to one side of the support plate 302. The movement of the support plate 302 is guided by the T-slot 401 and the T-block 402.

The other end of the screw rod 801 is fixed with a rotating pin 802. The screw rod 801 is driven to rotate by the rotating pin 802. During the rotation of the screw rod 801, the connecting rod 803 is driven to move inside the roller 105 through the mutual engagement transmission between the screw rod 801 and the inner wall of the rotating tube 103. During the movement of the connecting rod 803, the driving rod 601 is driven to move synchronously inside the roller 105.

[0032] The guide assembly includes a fixed plate 701 fixed inside the roller 105, a fixed tube 702 is fixed on the fixed plate 701, a spline groove is opened on the inner wall of the fixed tube 702, a spline shaft 703 is slidably connected to the spline groove, one end of the spline shaft 703 is fixed to one end of the driving rod 601, and the movement of the driving rod 601 is guided by the spline shaft 703 and the spline groove on the fixed tube 702.

[0033] The lifting assembly includes a strip plate 1106 on the side plate 101, a threaded rod 1101 is rotatably connected to the Z-shaped plate 10, a threaded tube 1102 is threadedly engaged on the threaded rod 1101, one end of the threaded tube 1102 is fixed to the strip plate 1106, a first motor 1103 for driving the threaded rod 1101 is installed on the Z-shaped plate 10, a sleeve 1105 and a slide rod 1104 are fixed to the strip plate 1106 and the Z-shaped plate 10, respectively, and the slide rod 1104 is slidably connected to the sleeve 1105. 105, the threaded rod 1101 is driven to rotate by the first motor 1103. During the rotation of the threaded rod 1101, the Z-type plate 10 and the identification camera 2 on the Z-type plate 10 are driven to be raised and lowered through the mutual meshing transmission between the threaded rod 1101 and the threaded tube 1102 and the guiding effect between the sleeve 1105 and the sliding rod 1104. The height of the identification camera 2 can be raised and lowered to facilitate the identification camera 2 to identify and sort materials at different heights.

[0034] The transmission assembly includes a gear 901 fixed to two rotating shafts 102 and one end of multiple rotating tubes 103. The gears 901 are connected by a toothed belt 902. A second motor 903 for driving the rotating shaft 102 is installed on the side plate 101. The rotating shaft 102 is driven to rotate by the second motor 903. During the rotation of the rotating shaft 102, the transmission between the toothed belt 902 and the gears 901 drives the conveying rollers 104 on the two rotating shafts 102 and the rollers 105 on the rotating tubes 103 to rotate. Through the rotation of the two conveying rollers 104 and the multiple rollers 105, the conveyor belt 106 is driven to transport between the two conveying rollers 104.

[0035] Working principle: When the automatic sorting equipment is sorting materials, the materials to be sorted are placed on the conveyor, and the materials are transported by the conveyor. During the transportation process, the recognition camera 2 is used to classify and identify different materials, and the sorting robot 12 is controlled to store and place the identified different materials in different positions, thereby completing the automatic sorting operation of the materials;

[0036] In the process of conveying the materials to be sorted by the conveyor, the materials are placed on the conveyor belt 106 and the second motor 903 is started. The second motor 903 drives the rotating shaft 102 to rotate. During the rotation of the rotating shaft 102, the transmission between the toothed belt 902 and each gear 901 drives the conveying rollers 104 on the two rotating shafts 102 and the rollers 105 on each rotating tube 103 to rotate. The two conveying rollers 104 and the plurality of rollers 105 are rotated to drive the conveyor belt 106 to be conveyed between the two conveyor rollers 104. During the conveying process, along with the rotation of each roller 105, one end of the support plate 302 arranged in each annular array on both sides of the roller 105 is used to lift and support the conveyor belt 106 during the conveying process, so that the conveyor belt 106 can be conveyed more stably.

[0037] As the conveyor is used, due to the difference in wear between one end of the support plates 302 set in the circular arrays on both sides of the roller 105 and the inner side of the conveyor belt 106, the length of each support plate 302 on both sides of the roller 105 exposed outside the roller 105 deviates, causing the support height of the support components on both sides of the roller 105 to the conveyor belt 106 to be different, further causing the conveyor belt 106 to appear high on one side and low on the other side. At this time, the conveyor needs to be stopped and the support height of the support component on one side of the roller 105 at the corresponding position needs to be adjusted. During the adjustment process, the screw rod 801 is driven to rotate by the rotating pin 802. During the rotation of the screw rod 801, the connecting rod 803 is driven to move inside the roller 105 through the mutual meshing transmission between the screw rod 801 and the inner wall of the rotating tube 103. During the movement, the driving rod 601 is driven to move synchronously inside the roller 105. During the movement of the driving rod 601, the tapered surface 602 and one end of each transmission rod 502 are counteracted to drive each transmission rod 502 and the support plate 302 at one end of the transmission rod 502 to move toward the outside of the roller 105. After the movement of each support plate 302, the length of each support plate 302 exposed outside the roller 105 is adjusted to increase the support height of the support assembly on one side of the roller 105 that is more severely worn for the conveyor belt 106, so that the support height of the support assembly on both sides of the roller 105 for the conveyor belt 106 is kept consistent, which solves the problem of one side of the conveyor belt 106 being higher than the other side, facilitates the stable transportation of the materials to be sorted on the conveyor, and further facilitates the automatic sorting equipment to identify and sort the conveyed materials.
