The lower end of the pressure rod 11 is fixedly connected to a flattening block 14 corresponding to the positioning groove 4. A spring 15 is inserted into the pressure rod 11 between the flattening block 14 and the lifting plate 9. The upper end of the pressure rod 11 is fixedly connected to an anti-slip block 16. In this structure, the betel nut vibration turning machine 2 is used to vibrate the cut betel nut into the positioning groove 4 once, and turn the betel nut over so that the cut surface of the betel nut faces upward and is embedded in the positioning groove 4. When the vibration turning is completed, the lifting cylinder 6 is started to drive the flattening block 14 on the lifting plate 9 to move downward, thereby flattening the betel nut in the positioning groove 4, avoiding the betel nut tilting and causing position deviation during the later brine making process, thereby improving the quality of the later betel nut processing;

[0026] And because the pressure rod 11 can slide in the sliding hole 10 on the lifting plate 9, when the flattening block 14 presses the betel nut down, the flattening block 14 moves up through the pressure rod 11 and compresses the spring 15, thereby preventing the flattening block 14 from directly contacting the betel nut and compensating for the height difference between different betel nuts, thereby avoiding crushing the betel nuts.

[0027] It should be noted that the positioning groove 4 is wide at the top and narrow at the bottom to adapt to the shape of the betel nut, so that the betel nut can only be embedded in the positioning groove 4 with the cut surface facing upward.

In this structure, the positioning plate 3 is transported by the belt conveyor mechanism 19, and the side guide mechanism 21 positions the left and right positions of the positioning plate 3 during transportation. When the positioning plate 3 reaches the gear mechanism 20, the positioning plate 3 stops conveying, and then the position of the positioning plate 3 is locked by the locking mechanism 22. Then the betel nut is put onto the positioning plate 3, and then the vibration motor 17 is started to drive the cam 30 to rotate. The cam 30 drives the slide plate 26 to move back and forth on the slide rail 29 through the push-pull handle 31, thereby driving the upper positioning plate 3 to vibrate left and right. During the vibration process, the hydraulic rod 27 can be started to drive the conveying frame 18 to tilt, thereby driving the positioning plate 3 to tilt, and then quickly turning the betel nut over and embedding it into the positioning groove 4 of the positioning plate 3 accordingly.
