[0042] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a measuring cylinder 11 is arranged on the top of the crushing and grinding device body 1, a feeding funnel 12 is installed on the top of the measuring cylinder 11, a laser sensor 13 is installed on the outer wall of the measuring cylinder 11, a PLC controller 14 is installed on the top of the crushing and grinding device body 1, the laser sensor 13 is connected to the PLC controller 14 through a wire, and the terminal of the PLC controller 14 is connected to the wiring inside the crushing and grinding device body 1 through a wire.

[0043] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a third servo motor 15 is provided on one side of the crushing and grinding device body 1, and the output of the third servo motor 15 moves through the crushing and grinding device body 1 and is connected to the coarse grinding roller group 8. One end of the coarse grinding roller group 8 moves through the crushing and grinding device body 1 and is connected to two first gears 16. The two first gears 16 are meshed and connected. Through the setting of the third servo motor 15, the two first gears 16 can be coordinated to drive the two coarse grinding roller groups 8 to rotate synchronously, thereby roughly grinding the crushed food raw materials, effectively saving the use cost.

[0044] according to Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, two fourth servo motors 17 are arranged on one side of the crushing and grinding device body 1, and the output end of each fourth servo motor 17 is movable through the crushing and grinding device body 1 and connected to a corresponding fine grinding roller group 9, and one end of each fine grinding roller group 9 is movable through the crushing and grinding device body 1 and connected to a second gear 18, and every two second gears 18 are meshed and connected.

Through the setting of the first guide plate 25, it can be ensured that the crushed food raw materials accurately fall between the two coarse grinding roller groups 8, and then undergo coarse grinding. Through the setting of the triangular guide block 26, it can be ensured that the coarsely ground food powder accurately falls to the two fine grinding roller groups 9, and then undergoes fine grinding. Through the setting of the second guide plate 27, it can be ensured that the processed food powder can accurately fall into the discharge pipe 19, thereby improving the continuity and integrity of the device during application, and further improving the overall work efficiency.

[0048] according to Figure 2 As shown, a protective frame 33 is provided on one side of the crushing and grinding device body 1, and a plurality of air holes 34 are opened through one side of the protective frame 33. Through the provision of the protective frame 33, the first gear 16 and the second gear 18 can be protected to prevent damage thereto by external factors, thereby extending the service life of the two and ensuring the normal operation of the device.

The crushed food raw materials fall down, and the first turntable 701 is rotated by the driving force of the single first servo motor 6, driving the connecting rod structure composed of the upper connecting rod 703, the connecting shaft 704 and the lower connecting rod 705 to rotate in a circle, thereby driving the second turntable 709 and the sorting shaft 710 connected thereto to rotate, and the crushed food raw materials are sorted by the sorting blades 711.

[0053] In the advanced grinding stage, the crushed food raw materials after sorting are guided by the first guide plate 25 to fall into the coarse grinding roller group 8. At this time, the third servo motor 15 is started to drive the coarse grinding roller group 8 to rotate, and the first gear 16 is driven to drive the two coarse grinding roller groups 8 to rotate synchronously to roughly grind the food raw materials. The coarsely ground food raw materials fall and are guided by the triangular guide block 26 to fall into the two fine grinding roller groups 9. At this time, the two fourth servo motors 17 are started to drive the corresponding fine grinding roller groups 9 to rotate, and the two groups of second gears 18 corresponding to the two fine grinding roller groups 9 are driven to drive the two fine grinding roller groups 9 to finely grind the food raw materials. The ground food powder is guided by the second guide plate 27 to fall into the discharge pipe 19.

[0054] During the discharging and drying stage, the pneumatic conveying device 20 is started to convey the food powder in the discharging pipe 19 to the drying bin 21, where it is heated by the electric heating plate 22 to be dried and fall into the collecting box 23. Then, the pull ring 24 is pulled to take the collecting box 23 out of the drying bin 21, and the processed food powder can be centrally processed.
