However, when the number of bamboo pieces is small, the upper roller will actually press the gathered bamboo pieces downward, the stress on the bamboo pieces will increase, the force on the knife will become complicated, and the breaking and cutting effect will be affected. Utility Model Content

[0005] In view of the problem in the prior art that when the number of bamboo pieces is small, the upper roller will actually press the gathered bamboo pieces downward, the stress on the bamboo pieces becomes greater, the force on the cutter becomes more complicated, and the cutting effect is affected.

Both sides of the bottom supporting mechanism 3 are provided with symmetrically distributed elastic clamping mechanisms 4. When the bamboo tube is broken by the blade, the bamboo pieces continue to move forward and approach the elastic clamping mechanism 4 along the driving thrust. When one end of the bamboo piece extends into the elastic clamping mechanism 4 located at the rear end, the elastic clamping mechanism 4 starts to work, and the broken bamboo pieces are gathered and fixed to the middle. The bottom supporting mechanism 3 is located at the stacked bamboo pieces to provide upward supporting force. Then the driving mechanism 2 is responsible for driving the mobile platform to move in the horizontal direction to transport the bamboo pieces to the next station.

The tails of the first clamping plate 43 and the second clamping plate 44 are rotatably connected with a third rotating shaft 48. The output end of the pushing cylinder 45 is fixedly connected to the third rotating shaft 48. The pushing cylinder 45 is started, and the pushing cylinder 45 drives the first clamping plate 43 and the second clamping plate 44 to rotate around the first rotating shaft 46 at the same time. In this process, the first clamping plate 43 and the second clamping plate 44 simultaneously stably gather and clamp the bamboo strips.

[0029] Reference Figure 2 , 3 The inner walls of the first clamping plate 43 and the second clamping plate 44 are fixedly connected with a plurality of springs 49 in the circumferential direction, and the ends of the springs 49 are fixedly connected with an arc-shaped contact plate 410, and the surface of the arc-shaped contact plate 410 is evenly and fixedly provided with a plurality of anti-skid rubber strips 411 distributed at equal intervals in the axial direction. In the process of closing and clamping the bamboo pieces, the arc-shaped contact plate 410 contacts the bamboo pieces through the anti-skid rubber strips 411 on the surface, thereby preventing slipping. Moreover, the arc-shaped structure of the arc-shaped contact plate 410 enables the bamboo pieces to slide along the arc-shaped surface when clamping the bamboo pieces, without causing hard squeezing, thereby avoiding damage to the bamboo pieces. At the same time, the plurality of springs 49 provide a buffering effect for the arc-shaped contact plate 410, thereby further preventing damage to the bamboo pieces.

The slider 25 and the guide rod 24 slide in cooperation to limit the horizontal movement of the screw block 23.

[0032] Working principle: After the bamboo tube is broken by the blade, the bamboo piece continues to move forward toward the elastic clamping mechanism 4 under the action of the driving thrust. When one end of the bamboo piece extends into the elastic clamping mechanism 4 at the rear end, the elastic clamping mechanism 4 starts to work and starts the push cylinder 45. The push cylinder 45 drives the first clamping plate 43 and the second clamping plate 44 to rotate around the first rotating shaft 46 at the same time. During this process, the first clamping plate 43 and the second clamping plate 44 simultaneously stably gather and clamp the bamboo piece, and gather and fix the broken bamboo piece to the middle. During this process, the arc contact plate 410 passes through the surface The anti-skid rubber strip 411 on the surface contacts the bamboo pieces, thereby preventing slipping. Moreover, the arc structure of the arc contact plate 410 can make the bamboo pieces slide along the arc surface when clamping the bamboo pieces, without causing hard squeezing, thereby avoiding damage to the bamboo pieces. At the same time, the multiple springs 49 provide a buffering effect for the arc contact plate 410, thereby further preventing damage to the bamboo pieces. The supporting cylinder 31 is responsible for driving the supporting plate 32 and the arc supporting plate 33 to move upward, thereby providing an upward supporting force for the stacked bamboo pieces, thereby making the stacked bamboo pieces more tightly gathered, thereby preventing the bamboo pieces from loosening.

[0033] Then the driving mechanism 2 is responsible for driving the mobile platform to move in the horizontal direction. The specific process is that the motor 21 drives the screw 22 to rotate and then drives the screw block 23 to move along the length direction of the rectangular frame 102. The screw block 23 then drives the mobile platform 5 to move through the support block 28, and the mobile platform 5 thereby drives the bamboo pieces to move. The slider 25 and the guide rod 24 slide in cooperation to limit the horizontal movement of the screw block 23, and transport the bamboo pieces to the next workstation, so as to achieve the stable and centered pulling of the bamboo pieces from the bamboo breaking machine, thereby ensuring the breaking and cutting effect.
