The sorting mechanism 5 is arranged below a certain area of the ball module belt 2 on the main frame 1 (the actual sorting station is required). The sorting mechanism 5 includes a plurality of rollers 521. The rollers 521 are arranged at intervals and the circumferential side surfaces of the rollers 521 abut against the balls 22. When the rollers 521 rotate, they drive the balls 22 to rotate, so as to move the goods placed on the balls 22 of the ball module belt 2. By adjusting the rotation direction of the rollers 521, the rotation direction of the balls 22 is changed, thereby adjusting the moving direction of the goods to achieve sorting.

[0049] Based on the fact that the present transmission device further includes the sorting mechanism 5, in a certain embodiment, such as Figures 5 to 7 As shown, the sorting mechanism 5 further includes a special-shaped bracket 51.

When the special-shaped bracket 51 installs the roller 521, the support assembly 3 is placed through the open slot 511, so that a plurality of rollers 521 and the support assembly 3 can be installed in a narrow space, and the support assembly 3 and the roller 521 do not interfere with each other.

[0050] Based on the fact that the sorting mechanism 5 includes the special-shaped bracket 51, in a certain embodiment, such as Figures 5 to 7As shown, multiple groups of roller units 52 are arranged at the top of the special-shaped bracket 51, and the roller units 52 are arranged at intervals of the opening grooves 511, that is, the roller units 52 are located between adjacent opening grooves 511; the roller unit 52 includes multiple rollers 521. Multiple rollers 521 are combined into one group of roller units 52, which is convenient for adjusting the rotation of a single roller unit 52 separately, and at the same time, multiple rollers 521 are arranged on the special-shaped bracket 51 at intervals in a narrow space.

[0051] Based on the special-shaped bracket 51 having multiple groups of roller units 52, as shown in FIG. Figure 6 As shown, in a certain embodiment, the multiple rollers 521 of the roller unit 52 include a powered roller 5211 and a driven roller 5212 that is transmission-connected to the powered roller 5211; the powered roller 5211 is connected to a controller 53.

Specifically, the powered roller 5211 is sleeved on the powered roller 5211 and the driven roller 5212 through an annular transmission belt 54 to achieve transmission connection; the controller 53 is arranged on the special-shaped bracket 51 and connected to the powered roller 5211, and the powered roller 5211 has its own internal drive device. By connecting and regulating the rotation of the powered roller 5211 through the controller 53, the rotation of the single group of roller units 52 can be regulated.

[0052] On the basis of multiple roller units 52 arranged at intervals of open slots 511 at the top of the special-shaped bracket 51, as shown in FIG. Figure 6 As shown, in a certain embodiment, a plurality of mounting portions 512 are respectively provided on the side of a plurality of opening slots 511 on the special-shaped bracket 51, and the mounting portion 512 includes an extension portion 513 extending toward the opening slot 511, and a gap is provided between the extension portion 513 and the other side of the opening slot 511, so as to support the component 3 extending out of the top surface of the special-shaped bracket 51 to support the ball module belt 2; the two ends of the roller unit 52 are respectively provided on the mounting portions 512 corresponding to the two special-shaped brackets 51, wherein one roller 521 is provided on the extension portion 513, and the other roller 521 is provided on the mounting portion 512. By extending the extension portion 513 toward one side of the opening slot 511, the area of ​​the mounting portion 512 is increased, so that a single group of roller units 52 can be installed on the mounting portion 512, and at the same time, the support component 3 can be placed in the opening slot 511.

[0053] Based on the fact that the sorting mechanism 5 includes a special-shaped bracket 51, as Figure 7As shown in the figure, the present transmission device further includes a lifting mechanism 6. The lifting mechanism 6 includes a telescopic cylinder 61 fixedly connected to the main frame 1 and capable of vertical telescoping; the telescopic cylinder 61 is located below the special-shaped bracket 51, and the telescopic end of the telescopic cylinder 61 is fixedly connected to the bottom of the special-shaped bracket 51; specifically, the telescopic end is fixedly connected to the connecting bottom plate connecting the two special-shaped brackets 51. By fixedly connecting the telescopic end of the telescopic cylinder 61 on the main frame 1 to the special-shaped bracket 51, the lifting movement of the special-shaped bracket 51 can be realized, that is, the lifting roller 521 abuts against the ball 22 at the back to achieve sorting; when there is no need to sort goods, the roller 521 is in a state where it does not abut against the ball 22; lifting and adjusting the roller 521 can reduce the transmission resistance of the ball module belt 2 and avoid noise generated by the roller 521 constantly abutting against the ball 22.

[0054] Based on the fact that the present transmission device includes a lifting mechanism 6, as Figures 6 to 7 shown, in a certain embodiment, a lifting mounting frame 62 is fixedly provided on the main frame 1; the telescopic cylinder 61 is fixedly arranged on the lifting mounting frame 62; a guiding mechanism for guiding the lifting and sliding of the special-shaped bracket 51 is provided on the lifting mounting frame 62. Specifically, the guiding structure includes a guiding hole provided on the lifting mounting frame 62 and a guiding shaft 7 slidably arranged in the guiding hole; the top end of the guiding shaft 7 is fixedly connected to the special-shaped bracket 51. Preferably, the guiding structures are respectively arranged on both sides of the telescopic cylinder 61 to connect the special-shaped bracket 51, enhancing the stability of the lifting on both sides of the special-shaped bracket 51. The telescopic cylinder 61 and the guiding structure can be installed through the lifting mounting frame 62, and the guiding mechanism can guide the lifting and sliding of the special-shaped bracket 51, improving the sliding stability of the special-shaped bracket 51.

[0055] During actual use, when heavy goods are placed on the ball module belt 2, the driving motor 41 of the driving component 4 is started to drive the driving wheel 42 to rotate. The driving wheel 42 drives the ball module belt 2 to slide through the transmission teeth. Under the support of the support bar and the sliding bar on its top, the problem of the middle part of the ball module belt 2 sinking and deforming and interfering with the driving wheel 42 or other devices is avoided; when the goods are transported to the sorting mechanism 5 and need to be sorted, the telescopic end of the telescopic cylinder 61 raises the special-shaped bracket 51 so that the roller 521 abuts against the multiple balls 22 on the chain plate 21. Among them, the power-driven roller 5211 rotates and drives the driven roller 5212 to rotate through the transmission belt 54. The outer circumferences of the two rollers 521 abut against the balls 22 to drive the balls 22 to rotate and move the goods placed on the balls 22 to achieve sorting; after the goods are sorted, when the telescopic cylinder 61 contracts, the special-shaped bracket 51 descends, and the power-driven roller 5211 and the driven roller 5212 are separated from the balls 22, and the goods on the ball module belt 2 are transported normally, avoiding abnormal noises generated by the power-driven roller 5211 and the driven roller 5212 constantly abutting against the balls 22.
