The protrusion 7-1 is located on the upper surface of the contour sheet 7 and extends upward. The protrusion 7-1 and the contour sheet 7 are integrally formed.

[0038] Bolts 6 and nuts 5 are provided between the baffle 4, the support seat 8 and the profiling piece 7. The bolts 6 pass through the baffle 4, the support seat 8 and the profiling piece 7 and are connected to the nuts 5. The two ends of the baffle 4 arranged opposite to each other form an outer eight structure. The baffle 4 plays a certain guiding role, and the top heights of the two baffles 4 are the same, which is convenient for the transmission of the bamboo pieces 15. Under the action of the bolts 6 and the nuts 5, the baffle 4, the support seat 8 and the profiling piece 7 are tightly fitted.

[0039] The bamboo pieces 15 are located between the corresponding baffles 4, with the outer circumference facing the milling cutter 18, the inner concave surface 15-1 of the bamboo piece facing upward, and the reference points 25 on both sides of the outer circumference of the bamboo piece leaning against the highest point of the protrusion 7-1.

[0041] The clamping mechanism 3 includes a fixing plate 9 and a screw 11. The fixing plate 9 is fixedly connected to the frame 1. The fixing plate 9 is fixedly connected to the frame 1 by bolts. The screw 11 extends downward through the fixing plate 9. The bottom of the screw 11 is connected to the pressing plate 13. A forked structure 11-1 is formed at the bottom of the screw 11. The forked structure 11-1 is sleeved on the pressing plate 13, and the forked structure 11-1 and the pressing plate 13 are fixedly connected by fixing bolts 12.

[0042] The screw rod 11 passes through the fixed plate 9, and the screw rod 11 is threadedly connected to the fixed plate 9. The position of the pressure plate 13 is adjusted according to the height position of the screw rod 11. The forked structure 11-1 is simultaneously abutted against both sides and the top of the pressure plate 13, so that the forked structure 11-1 and the pressure plate 13 have better stability. At the same time, the forked structure 11-1 is abutted against the top of the pressure plate 13 to prevent relative rotation between the pressure plate 13 and the forked structure 11-1.

[0043] A spring 10 is sleeved on the screw rod 11, the top of the spring 10 is against the fixed plate 9, and the bottom of the spring 10 is against the forked structure 11-1.

[0044] A rotating shaft 14 is provided between the pressing plate 13 and the frame 1 . The rotating shaft 14 is located at one end of the pressing plate 13 . The rotating shaft 14 rotates synchronously with the pressing plate 13 . The rotating shaft 14 and the pressing plate 13 are fixedly connected via a key and a keyway.

[0045] A transmission shaft 18-1 is provided between the milling cutter 18 and the frame 1. The milling cutter 18 and the transmission shaft 18-1 rotate synchronously. The milling cutter 18 and the transmission shaft 18-1 are fixedly connected by a key and a keyway. The transmission shaft is lifted and arranged on the frame 1. The position of the milling cutter 18 can be adjusted by lifting and lowering the transmission shaft 18-1.

[0046] A pressing plate 13 is pressed against the concave surface 15-1 of the bamboo piece at the upper position corresponding to the milling cutter 18. The pressing plate 13 can rotate around the rotating shaft 14. The position of the pressing plate 13 is adjusted by rotating the rotating shaft 14. After the pressing plate 13 is adjusted to a suitable position, the screw 11 is locked by a double nut structure 19. A screw 11 is connected with a fixing bolt 12 above the pressure point where the pressing plate 13 presses against the concave surface 15-1 of the bamboo piece. A spring 10 is provided on the external thread of the screw 11. One end of the spring 10 is pressed under the fixing plate 9. The external thread portion of the screw 11 passes through the frame fixing plate 9 and is fastened with a double nut structure 19.

[0047] During actual use, when the bamboo piece 15 enters from the direction of rotation facing the milling cutter 18, the baffle plate 4 on the supporting mechanism 2 limits the bamboo piece 15 to the left and right, and the reference points 25 on both sides of the outer circle of the bamboo piece rest on the highest point of the protrusion 7-1 of the contour piece 7. At the same time, the position of the pressing plate 13 is adjusted to a suitable position through the rotating shaft 14, so that the pressing plate 13 presses the concave surface 15-1 of the bamboo piece.

[0048] Under the dual action of the pressing plate 13 and the milling cutter 18 below, the milling cutter 18 cuts the outer cylindrical surface of the bamboo piece 15. Since the reference points 25 on both sides of the outer circle of the bamboo piece are used for reference positioning, the bamboo pieces 15 of different diameters present different cutting values ​​under the support of the highest point of the protrusion 7-1 of the profiling piece 7, that is, the small-diameter bamboo piece 20 will achieve a large-point cutting amount 21; the large-diameter bamboo piece 22 will achieve a small-point cutting amount; and the special-shaped round bamboo piece 23 will automatically correct and smooth, and achieve a suitable cutting amount. The cutting values ​​of the above three situations will change adaptively at any time with the large and small diameters and special-shaped circles of the bamboo piece 15, making the material utilization and processing of the bamboo piece 15 more scientific and reasonable.
