[0070] Example 1

[0071] like Figures 1 to 15 As shown, the belt-driven swing wheel sorting machine of this embodiment includes:

[0072] The frame 100 includes a housing 110, an upper cover plate 120 disposed on the top surface of the housing 110, and a bottom plate 130 disposed on the bottom surface of the housing 110; the upper cover plate 120 is provided with a plurality of through holes 111.

[0073] Multiple belt roller units 200 are provided, each corresponding to a through hole 111. All belt roller units 200 are mounted on the frame 100, and each belt roller unit 200 protrudes from its corresponding through hole 111. Each belt roller unit 200 includes a cylindrical support 210, a lower starting roller 220, two upper receiving rollers 230, and a belt component 240. The central axes of the two upper receiving rollers 230 are parallel and lie on the same horizontal plane. The lower starting roller 220, the two upper receiving rollers 230, and the belt component 240 are all located inside the cylindrical support 210. The two upper receiving rollers 230 are located above the lower starting roller 220, and the belt component 240 is wound around the outside of the two upper receiving rollers 230 and the lower starting roller 220. The cylindrical support 210 is rotatable relative to the frame 100.

[0074] When in use, the belt-type swing wheel sorter uses a belt roller unit 200 as the conveying mechanism that directly contacts the items. The belt roller unit 200 can rotate relative to the frame 100 so that the items can be conveyed in different directions. Since the belt roller unit 200 uses a belt component 240 to convey items, and the belt component 240 can convey items in the horizontal direction, the belt-type swing wheel sorter runs smoothly with little bumps when conveying and sorting items.

[0075] In this embodiment, the upper cover plate 120 is made of stainless steel material. The lower starting roller 220 is a servo motor roller, which makes the lower starting roller 220 have enough power and high load output function at low speed.

[0076] The lower starting roller 220 includes a starting roller middle part 221 and two starting roller end parts 222, the two starting roller end parts 222 are respectively connected with two ends of the starting roller middle part 221, and the starting roller middle part 221 is in cylindrical shape; along the axial direction of the lower starting roller 220, the diameter size of each starting roller end part 222 gradually decreases from the end connected with the starting roller middle part 221 to the end away from the starting roller middle part 221. This makes the lower starting roller 220 form a drum-shaped structure with the middle part bulging, and the two ends of the lower starting roller 220 are in a contracted structure. After the belt part 240 is wound on the starting roller middle part 221, the lower starting roller 220 can correct the deviation of the belt part 240.

[0077] The inside of the shell 110 is provided with a plurality of support parts 300; all the belt roller units 200 are arranged in several rows, the bottom of each cylinder part support 210 is connected with the rotating shaft 250; the rotating shafts 250 connected with the cylinder part supports 210 of all the belt roller units 200 in the same row are all installed on the same support part 300; all the cylinder part supports 210 of the belt roller units 200 in the same row are all hinged with a pull rod 400; the rotating shaft 250 of one of the belt roller units 200 at the end in the same row is connected with a starting element 500. In this embodiment, the starting element 500 is a servo motor.

[0078] The starting element 500 drives the rotating shaft 250 of the belt roller unit 200 at the end to rotate, the rotating shaft 250 drives the corresponding cylinder part support 210 to rotate, the cylinder part support 210 drives the pull rod 400 to swing, the pull rod 400 drives the cylinder part supports 210 of the remaining belt roller units 200 in the same row to rotate, and then the starting element 500 provides power for the left and right rotation of the belt roller units 200 in the same row. During the rotation of the belt roller units 200 in the same row, the pull rod 400 synchronously connects the whole row of belt roller units 200. The support part 300 is a transversely arranged part, and the support part 300 provides support for the rotating shaft 250 of the belt roller unit 200.

[0079] The number of the pull rods 400 is equal to the number of the rows of the belt roller units 200, and the number of the support members 300 is equal to the number of the rows of the belt roller units 200; the pull rod 400 comprises a rod body 410 and a plurality of rod body connecting portions 420 connected with the rod body 410, the rod body connecting portions 420 correspond to the cylinder portion supports 210 one by one, all the rod body connecting portions 420 are sequentially arranged along the length direction of the rod body 410, and each rod body connecting portion 420 is hinged with the corresponding cylinder portion support 210. During the transmission of the belt roller unit 200, the belt roller unit 200, the support member 300 and the pull rod 400 form a parallelogram four-bar linkage structure, and the pull rod 400 can conveniently drive the cylinder portion supports 210 in the same row to rotate.

The starting motor 510 provides power to the input transmission wheel 520, the input transmission wheel 520 drives the output transmission wheel 530 to rotate through the driving belt 540, the output transmission wheel 530 drives the rotating shaft 250 to rotate, and the starting motor 510 provides power for the left and right rotation of the belt roller unit 200 in the same row.

[0081] During the transmission of the pull rod 400, when the starting element 500 drives the rotating shaft 250 to rotate, the rotating shaft 250 drives the pull rod 400 to rotate, and since the pull rod 400 will form a dead point effect with the belt roller unit 200 when rotating 90 degrees. To solve the problem of dead point effect, in the case of limited space structure, the size of the output transmission wheel 530 is increased, the torque of the input transmission wheel 520 is increased, and low speed is matched to pass through the dead point. The rotating position of the pull rod 400 rotating 90 degrees only appears as a rotating limit position. In the normal working state, the swing angle of the pull rod 400 is 0 degree to 60 degrees in two directions.

In the belt-type balance wheel sorting machine, the control device 630 and the wiring are arranged in the driving receiving part 113, so that the control device 630 and the wiring form a side layout mode, which can meet the requirement that the height of the belt-type balance wheel sorting machine is below 300 mm. In the embodiment, the driving receiving part 113 is a driving card box, the control device 630 in the driving card box is a driving card, and the side-pulling driving motor 620 is a speed reducer.

[0084] The outer side of each rotating shaft 250 is sleeved with a spacer sleeve 260, and the spacer sleeve 260 is between the corresponding barrel portion support 210 and the support 300. The spacer sleeve 260 is an intermediate connecting piece between the rotating shaft 250 and the support 300, and the spacer sleeve 260 can be made of nylon material. The nylon spacer sleeve 260 has the characteristics of self-lubricating and low friction, which effectively suppresses the noise in the rotating process.
