[0023] An embodiment of a magnetic gear material conveying line of the utility model is as follows Figures 1 to 5 A magnetic gear material conveyor line is shown, and the conveyor line is composed of a loading conveyor section, a detection conveyor section and a discharging and sorting conveyor section from right to left, and is characterized in that: each conveyor section includes a main support mechanism, a driving mechanism, a driven mechanism and a rolling mechanism, the support mechanism is used for the installation and fixation of all mechanisms, the driving mechanism provides driving force for the conveyor line, the driven mechanism cooperates with the driving mechanism to drive the roller mechanism, and the roller mechanism drives the material to move;

[0024] The main support mechanism includes two parallel support rails, each support rail is composed of a plurality of support plates, and a bracket 19 is installed on the back side of the two support rails. The bracket 19 has a U-shaped groove, and the bracket 19 is detachably connected to the bearing cover plate 18;

[0025] The driving mechanism includes a magnetic gear shaft 16, which is connected in series with a magnetic gear 17, a shaft limiting ring 21, a bearing 20 and a driven wheel 12. The shaft limiting rings 21 are installed on both sides of the bearing 20. The bearing cover plate 18 presses the bearing 20 into the U-shaped groove of the bracket 19. The driving wheel 10 is installed directly below the driven wheel 12. The driving wheel 10 and the driven wheel 12 are connected through a synchronous belt 11. The central axis of the driving wheel 10 is fixedly connected with a stepping motor 9.

[0026] The driven mechanism includes a roller 24 and a second magnetic gear 22 located directly above the magnetic gear 17. The axial center line of the second magnetic gear 22 is ninety degrees to the axial center line of the magnetic gear 17. The second magnetic gear 22 is connected in series at both ends of the roller 24. The roller 24 is connected in series with a second bearing 23. The outer ring of the second bearing 23 abuts against the slot of the support plate and is pressed by the second bearing cover plate 25.

[0027] The support plate includes a front support plate A1, a front support plate B2, a rear support plate A3 and a rear support plate B4. The front support plate A1 and the front support plate B2 are spliced ​​into a first support rail, and the rear support plate A3 and the rear support plate B4 are spliced ​​into a second support rail. A support shaft 7 is installed between the first support rail and the second support rail. Reinforcing ribs 5 and a mounting floor 6 are installed on the back sides of the first support rail and the second support rail. The main support mechanism also includes a guide rail bracket connecting plate 8. The front support plate A1 and the front support plate B2, and the rear support plate A3 and the rear support plate B4 are assembled through the guide rail bracket connecting plate 8.

[0028] The magnetic gear 17 , the shaft limiting ring 21 and the bearing 20 rotate together with the magnetic gear shaft 16 . A plurality of magnetic gears 17 are installed on the magnetic gear shaft 16 at equal intervals. The number of the bearings 20 is equal to the number of the brackets 19 .

[0029] A plurality of rollers 24 are installed in the support rails to serve as material carriers, and the number of the second magnetic gears 22 is equal to the number of the magnetic gears 17 .

[0030] Working principle: The utility model mainly utilizes the principle that like-pole magnets repel each other and opposite-pole magnets attract each other. When the stepper motor 9 drives the magnetic gear shaft 16 to rotate through the synchronous belt 11, the magnetic gear 17 rotates accordingly. At this time, all the magnetic gears 17 on the driving mechanism rotate together with the magnetic gear shaft 16, resulting in a change in polarity. The change in the polarity of the magnetic gear 17 on the driving mechanism drives the rotation of the second magnetic gear 22 on the driven mechanism roller 24. The second magnetic gear 22 and the roller 24 are fixed together, so when the polarity changes, the roller 24 can rotate together. When all the rollers 24 rotate together, the conveying of the items can be completed.

[0031] It should be particularly noted that the magnetic gear 17 and the second magnetic gear 22 transmit attractive force or repulsive force through the magnetic field. Therefore, the magnetic gears of the driving mechanism and the driven mechanism can provide power in a non-contact manner. When the transported items exceed the load and the driving mechanism cannot carry them, the magnetic gear 17 on the driving mechanism will idle, thereby protecting the motor device of the driving mechanism. And because of the non-contact power transmission, there is no mechanical wear and noise during operation.

[0032] The utility model is designed according to actual needs, and each conveying section can work independently. The material flows into the right feeding conveying section to the station of the detection conveying section. After the station of the detection conveying section senses that there is material on the roller 24, it stops rotating. After the detection is completed, the roller 24 rotates again. After the material detection is completed, it flows to the discharging sorting section. Each conveying section works independently and cooperates with each other to meet the transportation and station production needs. The magnetic gear structure is simple to assemble, does not require high-precision matching, and the spacing of the roller 24 can be arbitrarily designed according to the size of the product. A conveyor belt can also be put on the roller 24 to cope with the transportation of small and micro items.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
