Therefore, in order to achieve the required grinding quality, it is necessary to reduce the rotation speed of the rotating rollers, which affects the grinding efficiency. If the rotation speed is increased, due to the small grinding area, leakage will occur, affecting the grinding effect. Summary of the invention

[0038] Example 2

[0039] See also Figure 2 , Figure 3and Figure 4 As shown, an automatic flour grinding equipment for wheat processing, based on the above embodiment, is provided with a reciprocating cleaning mechanism 5 on one side of the rolling roller 2, and the reciprocating cleaning mechanism 5 is used to clean the surface of the rolling roller 2; the reciprocating cleaning mechanism 5 includes a cleaning roller 51, a guide rod 52 and a driving assembly 53; the cleaning roller 51 is against the rolling roller 2, and the cleaning roller 51 is used to clean the surface of the rolling roller 2; the cleaning roller 51 is sleeved on the guide rod 52, and the cleaning roller 51 is slidably connected to the guide rod 52; the driving assembly 53 is provided at the end of the guide rod 52, and the driving assembly 53 is used to drive the guide rod 52 to rotate and reciprocate; by driving the guide rod 52 to reciprocate by the driving assembly 53, the cleaning roller 51 can be driven to clean different positions of the rolling roller 2.

[0040] Specifically, the driving assembly 53 includes a slide rail 531, a slider 532, a belt 533, the slide rail 531, a lever 534, a transmission gear 535 and a rack 536. The slide rail 531 is fixed in the grinding box 1, the slider 532 is slidably connected to the slide rail 531, and the belt 533 is rollingly connected in the grinding box 1; the lever 534 is fixed to the surface of the belt 533, and the lever 534 is slidably connected to the slider 532; the transmission gear 535 is sleeved on the end of the guide rod 52; the rack 536 is fixed on the slide rail 531, and the transmission gear 535 is meshed with the rack 536; illustratively, the lever 534 is driven by the belt 533 to slide around the belt 533, and the lever 534 drives the slider 532 to slide back and forth on the slide rail 531, and the transmission gear 535 rolls on the rack 536, thereby driving the guide rod 52 to rotate on the slider 532, which can drive the cleaning roller 51 to rotate, increase the cleaning area, and thus improve the cleaning effect.

[0041] For more details, see Figure 3 As shown, the reciprocating cleaning mechanism 5 also includes a groove wheel 5331, a servo motor 5332 and a spring 54.

[0042] It is worth mentioning that the cleaning teeth on the surface of the cleaning roller 51 of the present embodiment are not arranged around the cleaning roller 51. The purpose is that when the cleaning roller 51 is in the cleaning operation of the rolling roller 2, the rolling roller 2 rotates and pushes the cleaning roller 51 to slide on the guide rod 52 through the cleaning teeth. In order to facilitate the resetting of the cleaning roller 51, the cleaning teeth on the surface of the cleaning roller 51 are not arranged around the cleaning roller 51. In this way, when the surface of the cleaning roller 51 without cleaning teeth contacts the rolling roller 2, the cleaning roller 51 can be reset by the elastic force of the spring 54. This reciprocating process can achieve the effect of cleaning the rolling roller 2 during operation.

[0043] See also Figure 4 As shown, a groove 521 is provided on the outer surface of the guide rod 52, and a protrusion 511 that cooperates with the groove 521 is fixed to the inner wall of the cleaning roller 51, and the protrusion 511 is slidably connected with the groove 521; the purpose is that the guide rod 52 can drive the cleaning roller 51 to rotate through the cooperation between the groove 521 and the protrusion 511, and the cleaning roller 51 can also slide on the guide rod 52.
