The bamboo chopstick conveying device 2 conveys the bamboo chopsticks. At the same time, the bamboo chopstick pressing assembly 5 presses the bamboo chopsticks and makes the bamboo chopsticks rotate relative to the bamboo chopstick conveying device 2. At this time, the bamboo chopstick sharpening assembly 3 can sharpen one end of the bamboo chopsticks. The bamboo chopstick arc-forming assembly 4 cuts and sharpens the end of the bamboo chopsticks away from the sharpened end, thereby realizing the arc-forming of the other end of the bamboo chopsticks while sharpening the bamboo chopsticks.

When the conveying turntable 22 rotates and conveys the bamboo chopsticks to the upper side of the conveying turntable 22, they come into contact with the bamboo chopstick pressing assembly 5. The bamboo chopstick pressing assembly 5 generates a pressing force on the bamboo chopsticks, and at the same time drives the bamboo chopsticks to rotate in the bamboo chopstick card slots 23. At the same time, the bamboo chopstick arc-inverting assembly 4 performs arc-inverting on the ends of the bamboo chopsticks, and the bamboo chopstick sharpening assembly 3 performs sharpening treatment on the bamboo chopsticks. When the bamboo chopsticks are sharpened and arc-inverted, they are conveyed to the bamboo chopstick collecting bin 25 through the conveying turntable 22.

[0026] During the process of the conveying turntable 22 transferring and conveying the bamboo chopsticks, the lower side of the bamboo chopsticks is supported by the conveying turntable 22, and the upper side of the bamboo chopsticks is limited by the pressing arc-shaped strip 27, which can effectively prevent the bamboo chopsticks from falling out of the bamboo chopstick card slots 23, thereby making the production and processing of bamboo chopsticks more stable.

[0027] A plurality of limiting members 55 are arranged in an arc on the pressing frame 51. The limiting members 55 apply a force from the inner side of the pressing belt 53, and the outer side of the pressing belt 53 is in contact with the bamboo chopsticks. Thus, the pressing belt 53 can better apply the force on the bamboo chopsticks and rotate the bamboo chopsticks through friction, so as to better sharpen and arc-invert the bamboo chopsticks.

[0028] Refer to Figure 9 、 Figure 10 , a bamboo chopstick blanking plate 241 is installed at the bottom of the bamboo chopstick feeding bin 24. The bamboo chopstick blanking plate 241 is inclined downward from the bamboo chopstick feeding bin 24 to the direction of the conveying turntable 22. A turntable groove 242 is provided on the side of the bamboo chopstick blanking plate 241 close to the conveying turntable 22, and the conveying turntable 22 is matched with the turntable groove 242; The bamboo chopsticks are placed in the bamboo chopstick feeding bin 24 and move downward along the bamboo chopstick blanking plate 241 under the action of their own gravity. The conveying turntable 22 is arranged in the turntable groove 242, and when the bamboo chopsticks come into contact with the conveying turntable 22, they are automatically clamped in the bamboo chopstick card slots 23; it is more convenient for the bamboo chopsticks to be clamped in the bamboo chopstick card slots 23 of the conveying turntable 22.

[0029] Refer to Figure 11, on one side of the bamboo chopstick storage bin 25 close to the conveying turntable 22, there is a bamboo chopstick recovery board 251. The bamboo chopstick recovery board 251 slopes upward from the bamboo chopstick storage bin 25 to the direction of the conveying turntable 22. A bamboo chopstick pushing board 252 is installed on the bamboo chopstick recovery board 251. The bamboo chopstick pushing board 252 is arranged between the conveying turntables 22. The bamboo chopstick pushing board 252 is used to push the bamboo chopsticks from the conveying turntable 22 into the bamboo chopstick storage bin 25. When the conveying turntable 22 conveys the bamboo chopsticks to the position of the bamboo chopstick storage bin 25, the bamboo chopstick pushing board 252 installed on the bamboo chopstick recovery board 251 ejects the bamboo chopsticks from the bamboo chopstick card slots 23 and slides along the bamboo chopstick pushing board 252 into the bamboo chopstick storage bin 25, thus effectively preventing the processed bamboo chopsticks from not being separated from the bamboo chopstick card slots 23 in time.
