[0036] See also Figure 1 and Figure 2 The food sorting device 100 also includes a positioning mechanism 70, which is arranged between the fixing frame 80 and the sorting mechanism 50. The positioning mechanism 70 includes a mounting block 71, a baffle 72 and a positioning driver 73. The mounting block 71 is fixedly connected to the outer wall of the feed channel 30, and the positioning driver 73 is fixedly connected to the mounting block 71. The baffle 72 is transmission-connected to the positioning driver 73. A clearance hole is provided on the side wall of the feed channel 30.

When the comparison result is obtained, the controller activates the positioning actuator 73 to reset the baffle 72, and controls the conveyor drive 24 to resume operation. The second position sensor monitors whether the dried fruit package has reached the corresponding discharge channel 60.

[0040] The food sorting device 100 of this embodiment operates as follows: During operation, a dried fruit package is placed on the conveyor belt 23. Driven by the conveyor driver 24, the dried fruit package passes the first position sensor. The controller then controls the positioning driver 73 to operate, causing the end of the baffle 72, away from the positioning driver 73, to pass through the clearance hole and extend into the feed channel 30, thereby stopping the dried fruit package. Simultaneously, the controller controls the conveyor driver 24 to stop operation and the CCD camera 40 to take a photo of the dried fruit package, generating a test image. Based on the comparison result between the test image and a standard image stored in the controller, the controller controls the sorting driver 54 to operate, causing the dried fruit package to enter the corresponding discharge channel 60 for discharge. When the comparison result is obtained, the controller controls the positioning driver 73 to operate, causing the baffle 72 to return to its original position. The controller then controls the conveyor driver 24 to resume operation, and the dried fruit package, transported by the conveyor belt 23, enters the corresponding discharge channel 60 for discharge.
