[0002] When sawing bamboo with a sawing machine, a saw blade is usually used to saw a bamboo into bamboo tubes one by one. The sawing machine does not have a coaxial multi-blade saw with multiple saw blades connected in series, so that multiple bamboo tubes cannot be sawed at one time. The reason is that the bamboo is not a complete straight cylinder, so when the bamboo is sawn off, the sawn-off bamboo tube will be displaced, causing the saw teeth to collapse and the saw blade to be damaged quickly. Therefore, the traditional sawing of raw bamboo does not use a coaxial multi-blade saw. SUMMARY

[0046] The working principle includes the feeding process, the clamping process, the sawing process, and the unloading process.

[0047] Feeding process: The material is conveyed to the workbench 6 by manual or mechanical conveying through the previous process.

[0048] Clamping and holding process: such as Figures 1-6 As shown, there are 8 pushing mechanisms 2 and 8 pressing mechanisms 3, with two pushing components 21 on each pushing mechanism 2. After the material is placed, the pushing component 21 is located below the worktable 6, and the pressing cylinder 31 extends to press the material with the pressing block 32. Then, the pushing drive source 22 extends, driving the drive transmission component 23 to rotate around the transmission fixing component 24. Since the pushing component 21 and the drive transmission component 23 are connected by a hinge structure, the pushing component 21 can rotate around the center of the hinge hole, thus the pushing component 21 will move upward. The pushing component 21 is held in place by the pushing elastic component 25 on both sides, which prevents the pushing component 21 from moving randomly. It only has a certain swaying motion from side to side under the action of spring tension. When the pushing component 21 moves upward, it presses against the bottom of the bamboo. Since the bamboo is not a perfectly straight cylinder, the left and right swaying of the pushing component 21 ensures that the pushing component 21 accurately holds the center of the bamboo, ensuring the stability of the bamboo. When the pusher 21 rises and passes through the worktable 6, the locking drive source 28 extends, and the conical block 29 at its upper end pushes the locking plates 27 on both sides, causing the locking plates 27 to press the pusher 21 against the elastic fixing member 26, thereby locking the pusher 21 and preventing it from moving. The purpose of this is to ensure that the Y-shaped fork always remains in a stationary state. After the bamboo is cut, the Y-shaped fork presses against the cut bamboo tube from the bottom, and the pressing block 32 above presses down on the bamboo tubes of the same group from above. In this way, even if the bamboo is cut into sections, each bamboo tube remains in a fixed position under the bidirectional force of the Y-shaped fork and the pressing block 32, thus preventing the saw blade from breaking.

[0049] Sawing process: When the tool moving source 41 is working, it drives the lever transmission component 42 to move. Through the structure of long and short arms, the lever transmission component 42 can quickly push the tool moving table 44 to reciprocate up and down, thereby completing the entire action of sawing the bamboo tube in a rhythmic manner.

[0050] Blanking process: after sawing, 8 pushing mechanisms 2 and 8 pressing mechanisms 3 return to the original position, the sawed bamboo tube falls on the workbench 6, the chain wheel 52 drives the chain 51 to move, and the push rod 53 pushes the bamboo tube out of the workbench 6.

[0051] The above process is repeated to realize continuous work.

[0052] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different.
