[0039] The implementation principle of the nutritional supplement dispensing equipment in this embodiment is as follows: in use, first, the granular nutritional supplement produced is poured into the spiral dispensing machine 4, then the supplement is gradually guided into the hopper 5 by the spiral dispensing machine 4, at this time, the electromagnetic valve can be opened and the supplement can fall into one of the dispensing grooves 9 according to the influence of gravity, then the residual gear 16 can be driven to rotate by starting the servo motor 15, and because the tooth blocks of the residual gear 16 are meshed and connected with the full gear 18, when the residual gear 16 rotates, the full gear 18 is disconnected through the intermittent tooth blocks, so as to drive the full gear 18 to rotate regularly and intermittently, so as to drive the dispensing disc 8 to rotate synchronously through the connecting shaft 17, so that the dispensing disc 8 rotates intermittently at a set frequency and speed, such a driving mode is not only stable and reliable, but also can accurately control the angle and speed of rotation through the controller 2, to ensure the accuracy and efficiency of the dispensing process, and because the bottom of the dispensing disc 8 is attached to the fixed disc 7, when the dispensing disc 8 rotates, the supplement in the dispensing groove 9 will also move, and through the high-definition camera 20, the appearance of the supplement can be checked during the movement process, when the supplement is damaged, the warning light 21 can send an alarm and stop the equipment operation in time to inform the staff to take out the damaged supplement in time, so as to avoid affecting the product quality and user experience, and with the intermittent rotation of the dispensing disc 8, a plurality of dispensing grooves 9 can intermittently pass through the discharge end of the hopper 5, so that the supplement can enter different dispensing grooves 9 in turn, and because the shape and size of the dispensing groove 9 are fixed, and the rotation of the dispensing disc 8 is accurately controlled by the driving mechanism, therefore, the amount of each dispensing can be accurately controlled, and high-precision dispensing can be realized;
[0040] When the sub-packaging tank 9 drives the supplement to move above the discharge port 10, the supplement in the sub-packaging tank 9 will automatically flow into a collection box 14 in the fixed frame 13 through the guide of the connecting pipe one 11 and the connecting pipe two 12 according to the gravity effect, so as to realize automatic equal packaging, effectively improve the product quality and user experience, and when the supplement is discharged through the connecting pipe two 12, it will preferentially fall in the corresponding flow guide plate 22 and contact the buffer pad 23. At this time, through the buffering guide of the flow guide plate 22 and the buffer pad 23, the integrity of the supplement can be effectively maintained to avoid its crushing, and the supplement can also be accurately sent to the corresponding collection box 14 through the inclined flow guide plate 22. When the supplement falls in a collection box 14, the weight of the supplement can be accurately measured through the weight sensor 28 at the bottom, and when the preset specification weight or a collection box 14 is full, the electric telescopic rod 27 can be started to operate to drive the adjusting block 25 to rotate around the fixed rod 24. Since the connecting pipe one 11 is rotationally connected with the discharge port 10 and the connecting pipe two 12 is fixedly connected with the adjusting block 25, the connecting pipe two 12 can be angularly adjusted by rotating the adjusting block 25 to adjust one end of the connecting pipe two 12 above another collection box 14, so as to realize the function of automatically switching the collection box 14 without manual adjustment, greatly improving the packaging efficiency and automation degree. Since the electric telescopic rod 27 is electrically connected with the controller 2, the operation time of the electric telescopic rod 27 can be accurately controlled through the preset program, so as to ensure the accuracy and stability of each adjustment.
