The limiting stroke of the bracket can be adjusted according to the picking stroke of the lifting roller group 103, which is convenient for controlling the transfer rate of the chopstick body to be effectively guaranteed.

[0070] The specific method of using the present invention is as follows: when using the present invention, the operator aligns a large number of cylindrical chopstick bodies with the side walls of the chopstick box 2 and places them, and changes the discharge quantity and speed of the discharge port by adjusting the extension height of the shovel plate 203, which is convenient for simple arrangement and the material collection process of the lifting roller group 103. At this time, the vertical roller 122 on the cylindrical chopstick body lifting roller group 103 comes into contact with the surface of the chopstick body during the rotation process, and the chopstick body at the farthest end of the bracket is lifted upward by the rotation force. The bracket is set at both ends of the discharge port, and the travel connection point of the lifting roller group 103 is located between the two brackets. Finally, the chopstick body passes through The lifting and conveying functions of the lifting and blocking roller group 103 are fixed inside the semicircular hanger 108. When the semicircular hanger 108 rotates to the transmission shaft 5 132, the vertical roller 122 rotates downward and loses contact with the chopstick body. At this time, the corresponding upper semicircular hanger 2 112 rotates downward. By synchronously driving the reverse transport group 102 and the forward transport group 101, the semicircular hanger 108 and the semicircular hanger 2 112 can be located on the same round seat, so that the surface of the chopstick body is limited. The end point push cylinders 110 at both ends push one end of the chopstick body to the inside of the upper grinding wheel track 117 and the lower grinding track 119 for grinding. The chopstick body can move along the gradually decreasing grinding line of the upper grinding wheel crawler 117 and the lower grinding crawler 119, and the side vertical stopper 109 plays the role of side limit. The bottom of the pressing plate 113 has a frosted surface, which can come into contact with the surface of the chopstick body. It can simply ensure that the chopstick body can rotate when the friction force at one end is large, and at the same time provide static pressure in normal state. In another embodiment, when the chopstick body needs to be intermittently ground into a flat body, the pressing height of the pressing plate 113 can be changed to increase the static friction between the chopstick body and the bottom of the pressing plate 113. After the chopstick body leaves the top conveyor belt 104, The tip is formed into a flat body, and then the chopstick body is polished by the polishing assembly 116. The formed chopstick body is conveyed downward through the oblique selection conveyor belt 107. In addition, during the transportation process of the top conveyor belt 104, the oblique observation eye 125 scans and photographs the chopstick body. By measuring the transmission speed of the semicircular hanger 108, the first jet 134 and the second jet 135 are coordinated to perform timed jets toward one end, and waste and defective chopstick bodies are respectively sprayed into the corresponding placement and selection box 3. When the chopstick body runs to the position between the transmission shaft 2 129 and the transmission shaft 3 130, one end of the storage cabin 303 picks up the chopstick body to one side and introduces it into the storage cabin 303.

[0071] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense.
