The other end of the connecting shaft 62 passes through the base 1, and the connecting shaft 62 is rotatably connected to the base 1. A second bracket 15 is fixedly provided on the other side of the base 1, and a motor 14 is fixedly mounted on the second bracket 15. The output shaft of the motor 14 is fixedly connected to the connecting shaft 62 via a coupling. The motor 14 can drive the connecting shaft 62 and the transmission gears 61 to rotate, thus realizing the transmission function of the transmission chain 6.

[0023] In this embodiment, a connecting seat 5 is fixedly connected to the slide 4, for reference. Figure 6 The connecting seat 5 is provided with a sliding groove 53, which extends in a second direction. A slider 51 is provided inside the sliding groove 53, and the slider 51 is slidably connected to the connecting seat 5 in the second direction. The second direction is perpendicular to the first direction, and in this embodiment, the second direction is a vertical direction.

[0024] Furthermore, a connecting block 52 is fixedly connected to the slider 51, and a connecting plate is fixedly connected to the side of the conveyor chain 6, with the connecting block 52 rotatably connected to the connecting plate. When the conveyor chain 6 is conveying, it can move the connecting block 52, the slider 51, and the slide table 4. The straight section of the conveyor chain 6 includes an upper conveying section 601 and a lower conveying section 602. When the connecting block 52 is located between the upper conveying section 601 and the lower conveying section 602, the slide table 4 moves in the first direction.

[0025] During the transmission process of conveyor chain 6, refer to Figure 6 When the connecting block 52 is located in the upper conveyor section 601 and the slider 51 is in the upper limit position, the connecting block 52, slider 51, and slide table 4 move towards the slitting blade 7. When the connecting block 52 passes through the arc section of the conveyor chain 6, the slider 51 moves downward along the slide groove 53, causing the connecting block 52 to reach the lower conveyor section 602. (Refer to...) Figure 7 When slider 51 is at its lower limit position, connecting block 52, slider 51 and slide table 4 move away from the slitting blade 7, thus realizing the reciprocating movement of slide table 4 and top block 41.

[0026] Furthermore, a limiting plate 8 is provided on the base 1, the limiting plate 8 is located behind the slitting blade 7, and the slitting blade 7 is located between the top block 41 and the limiting plate 8. A limiting groove 81 is provided on the side of the limiting plate 8 facing the slitting blade 7, the limiting groove 81 is used to accommodate the head of the bamboo strip obtained after the bamboo tube material is slited.

[0027] In this embodiment, the area of ​​the limiting groove 81 is larger than the area of ​​the circular end face of the slitting blade 7, and the orthographic projection of the slitting blade 7 on the limiting plate 8 is located inside the limiting groove 81, ensuring that the bamboo strip head can be completely accommodated inside the limiting groove 81.

[0028] The aforementioned limiting plate 8 is slidably connected to the base 1, and the limiting plate 8 is connected to the base 1 via an elastic component 12. (See reference) Figure 5 The elastic component 12 includes a movable block 121, a guide rod 122, an elastic element 123, and a cylinder 124. The cylinder 124 is fixedly connected to the bottom of the base 1 and extends in a first direction. The movable block 121 and the elastic element 123 are located inside the cylinder 124. The movable block 121 can move along the cylinder 124. One side of the movable block 121 is fixedly connected to the first end of the guide rod 122. The second end of the guide rod 122 extends out of the cylinder 124. A connecting rod 9 is fixedly connected to the extended end of the guide rod 122. The connecting rod 9 is fixedly connected to the limiting plate 8.

[0029] Furthermore, the elastic element 123 is sleeved on the outside of the guide rod 122. The elastic element 123 is located between the inner wall of the cylinder 124 and the movable block 121. The elastic element 123 is in a compressed state, and its extension force makes the limiting plate 8 in its original position, that is, the closest position between the limiting plate 8 and the slitting blade 7.

[0030] In this embodiment, there are two connecting rods 9, and guide plates 13 are respectively provided on both sides of the base 1. The guide plates 13 are slidably connected to the connecting rods 9 in the first direction. The guide plates 13 are used to support the connecting rods 9, so that the movement of the limiting plate 8 is more stable.

[0031] The working process of this bamboo cutting device is as follows: When the top block 41 is in its original position, that is, when the top block 41 is far away from the slitting blade 7, the worker places the bamboo tube material into the storage trough 10, with the end face of the bamboo tube material facing the slitting blade 7. The motor 14 drives the connecting shaft 62 and the transmission gear 61 to rotate. The transmission gear chain 6 moves the slide table 4 and the top block 41, and the top block 41 can push the bamboo tube material to move. At this time, the connecting block 52 is located in the upper transmission section 601, and the slider 51 is located in the upper limit position. At this time, the connecting seat 5, the slide table 4 and the top block 41 move towards the slitting blade 7. The end face of the bamboo tube material passes through the slitting blade 7 to realize the slitting of the bamboo tube material and obtain bamboo strips. The head of the bamboo strip obtained after the bamboo tube material is slid can enter the limiting groove 81 of the limiting plate 8. The limiting groove 81 can limit the dispersion of the bamboo strip head, making it easier for the worker to pick up the slid bamboo strip. The limiting plate 8 is connected to the base 1 through the elastic component 12. The bamboo tube can push the limiting plate 8 to move, so that it adapts to the displacement of the bamboo tube head. After the bamboo tube material is cut, the connecting block 52 on the slider 51 reaches the top of the arc section of the conveyor chain 6. After the worker removes the bamboo strips, the limiting plate 8 automatically returns to its original position under the action of the elastic component 12. The conveyor chain 6 continues to convey the slide table 4 and the top block 41. The slider 51 moves downward along the slide groove 53, and the connecting block 52 reaches the lower conveyor section 602. (Reference) Figure 7 When slider 51 is at its lower limit position, slide 4 and top block 41 move away from the slitting blade 7, so that top block 41 returns to its original position.
