The bamboo strip planing machine transports the bamboo strips to the bamboo strip collecting mechanism, and the bamboo strip grasping and moving mechanism grabs a preset number of bamboo strips from the bamboo strip collecting mechanism and moves them to the double semi-circular sorting device; after the double semi-circular sorting device flips the bamboo strips, they are sequentially transported to the strapping machine through the roller pressing and conveying device and the roller auxiliary conveying device for strapping. Through the cooperation between the above mechanisms, the sorting and strapping of the bamboo strips are completed.

[0027] As Figure 2a-Figure 2b shown, the bamboo strip collecting mechanism of this embodiment includes a machine frame 12 arranged on one side of the bamboo strip planing machine, and a number of vertical support rods 301 and baffle plates 4 arranged on the machine frame 12. The number of vertical support rods are symmetrically distributed left and right and spaced on the machine frame. The space between the left and right symmetries is used to place the bamboo strips, and the other end of the bamboo strips leans against the baffle plate 4 provided at the tail of the number of vertical support rods. After the bamboo strips 2 are planed and formed by the bamboo strip planing machine 1, they are transmitted to the bamboo strip collecting mechanism and placed in the spaces between the support rods 301 that are symmetrically distributed left and right at intervals. One end of the bamboo strip 2 leans against the inner side of the baffle plate 4, so that the bamboo strips 2 processed and formed by the bamboo strip planing machine 1 are neatly stacked in the bamboo strip collecting mechanism. The vertical support rods 301 and the baffle plates 4 are both fixedly installed in the machine frame 12.

[0028] The grasping and moving mechanism of this embodiment includes a stroke propulsion cylinder 9, a grasping propulsion cylinder 7, a guide rod 6, a grasping propulsion cylinder mounting plate 8, and a clamping cylinder 10. The guide rod 6 is arranged above the double semi-circular sorting device and the bamboo strip collecting mechanism; the clamping cylinder 10 is installed on one side close to the bamboo strip collecting mechanism.

The push rod of the grasping propulsion cylinder 7 is connected to the clamping cylinder 10 for clamping a preset number of bamboo strips; the grasping propulsion cylinder mounting plate 8 is connected to a slider 40 that can slide on the guide rod 6. Specifically, the stroke propulsion cylinder 9 is installed on one side of the frame 12 close to the bamboo strip collecting device, and the head end of its push rod is connected to the grasping propulsion cylinder mounting plate 8. Two grasping propulsion cylinders 7 are installed on the upper plane of the grasping propulsion cylinder mounting plate 8. The head end of the push rod of a single grasping propulsion cylinder 7 is fixedly installed with a clamping cylinder 10, and a pair of clamping jaws 11 are distributed on each clamping cylinder 10. Sliders 40 are fixedly installed at both sides of the lower plane of the grasping propulsion cylinder mounting plate 8. The inner holes of the sliders 40 pass through the guide rod 6, so that the grasping propulsion cylinder mounting plate 8 together with the grasping propulsion cylinders 7 fixed thereon can move back and forth along the guide rod 6.

[0029] Combined with Figure 4 , Figure 5 As shown, the double semi-circular sorting device of this embodiment mainly includes a power source installed on the frame, two fixed seats 14, two groups of double semi-circular structures 16, and two baffles 15. The fixed seats 14 adopt a cubic shell, and the baffles are preferably thin steel baffles. Each group of double semi-circular structures 16 is installed in a cubic shell. The double semi-circular structure 16 is a pair of semi-circular bodies that are split in half. A baffle 15 is installed at the place where the centers of the two semi-circular bodies are split in half. The outer circular part of the double semi-circular structure 16 is installed in the cubic shell in an embedded manner and can rotate. In this embodiment, a power source is provided at one of the fixed seats. The power source includes a third motor 31, a coupling 33, a turntable 34, a connecting rod 35, and a motor support 32. The third motor 31, the coupling 33, the turntable 34, and one end of the connecting rod 35 are connected in sequence; the other end of the connecting rod 35 is connected to the end face of a semi-circular body. The third motor is preferably a stepping motor such as Figure 5 As shown, the two fixed seats 14 and the two groups of double semi-circular structures 16 are symmetrically arranged along the length direction of the bamboo strip 2. A connecting rod 35 is connected to one of the groups of double semi-circular structures 16. This connecting rod is connected to one side plane of the turntable 34, and the center of the other side plane of the turntable is connected to the third motor 31 through the coupling 33. The third motor 31 is installed on the motor support 32; as Figure 4 shown, the double semi-circular sorting combination formed by the other group of paired double semi-circular structures 16, the baffle 15, and the fixed seat 14 is not provided with a power source.

[0030] Combined Figure 4 、 Figure 5 As shown, this embodiment adopts four sets of roller pressing and conveying devices, which are symmetrically distributed on the outer sides of the double semi-circular sorting device in a left-right symmetric manner. Each set of roller pressing and conveying devices respectively includes a friction roller 20 arranged longitudinally, a first cylinder 17, a first motor 21, a cylinder support 18, and a U-shaped friction roller support 19. Among them, the first cylinder 17 is fixedly installed on the cylinder support 18, the push rod head end of the first cylinder 17 is fixedly installed with a U-shaped friction roller support 19, the opening end of the U-shaped friction roller support 19 is installed with a friction roller 20, and a first motor 21 is also fixedly installed on the U-shaped friction roller support 19. The first motor 21 can drive the friction roller 20 to rotate, and the U-shaped friction roller support 19 together with the friction roller 20 and the first motor 21 can make a translational movement through the push rod of the first cylinder 17.

[0031] Combined Figure 4 As shown, the roller auxiliary conveying mechanism of this embodiment mainly consists of two upper pressing rollers 24, four upper pressing roller supports 22, two side pressing rollers 25, a second cylinder 23, two cylinder seats 26, two side pressing roller supports 27, and two second motors 28, etc. Among them, the two side pressing rollers 25 are respectively installed in the two side pressing roller supports 27, and the rotational power of the two side pressing rollers 25 comes from the two second motors 28 installed on the two side pressing roller supports 27. The whole set consisting of the side pressing roller 25, the side pressing roller support 27, and the second motor 28 can be pushed and translated together by the push rod of the second cylinder 23. The two upper pressing rollers 24 are respectively installed on the front and rear sides of the side pressing rollers 25. Each upper pressing roller 24 is installed and fixed on the frame 12, specifically on the tabletop 13 of the frame, through two upper pressing roller supports 22. The second cylinder 23 is installed on the cylinder seat 26.

[0032] Combined Figure 4 As shown, the bundling machine 29 is located on one side near the output end of the roller auxiliary conveying mechanism, and the conveyor belt 30 is located on the other side of the bundling machine 29.

[0033] The working principle of the double semi-circular full-automatic bamboo strip sorting and bundling machine in this embodiment is as follows.

[0034] (1)The bamboo strip grasping and combining device starts to perform the first step of work: The stroke propulsion cylinder 9 starts to work, pushing the grasping propulsion cylinder mounting plate 8 together with the two grasping propulsion cylinders 7 to move along the guide rod 6 towards the bamboo strip collecting mechanism. When the grasping propulsion cylinder 7 reaches above the bamboo strip collecting mechanism, the grasping propulsion cylinder 7 starts to work, and the push rod drives the clamping cylinder 10 to move downward. At this time, the jaws 11 on the clamping cylinder 10 are just located at the interval positions of the upright support rods 301 distributed at intervals in the bamboo strip collecting mechanism, and it is convenient to grasp the bamboo strips 2 neatly arranged on the upright support rods 301. The number of jaws 11 and the number of bamboo strips 2 grasped at one time can be pre-designed and adjusted according to actual needs (for example, the number of bamboo strips 2 grasped at one time is 5, or 6, or 10, etc.). After the jaws 11 grasp the specified number of required bamboo strips 2, the push rod on the clamping cylinder 10 retracts. When it retracts to the specified position, the stroke propulsion cylinder 9 continues to perform the second stroke propulsion action, pushing the grasping propulsion cylinder mounting plate 8, the grasping propulsion cylinder 7, the clamping cylinder 10, and the grasped bamboo strips 2 to run above the double semi-circular sorting device. At this time, the grasping propulsion cylinder 7 works, driving the push rod to drive the clamping cylinder 10 to approach the middle opening groove of the double semi-circular structure 16. When it reaches the specified position, the jaws 11 are released, and the specified number of bamboo strips 2 just fall into the middle opening groove of the double semi-circular structure 16 and are blocked by the baffle 15 in the upper half of the opening groove.

[0035] (2)As Figure 3 , Figure 5 shown, at this time, the stacked height dimension of the specified number of bamboo strips 2 is just slightly lower than (or lower than) the maximum outer diameter of the double semi-circular structure 16. The third motor 31 on the double semi-circular sorting device 5 with a power source starts to work, driving the turntable 34 to drive the overall of a certain number of bamboo strips 2, the double semi-circular structure 16, and the baffle 15 that have been placed in the middle opening groove of the double semi-circular structure 16 to rotate 180 degrees in the fixed seat 14; at this time, the bamboo strips 2 that were originally in the upper half of the opening groove of the double semi-circular structure 16 are flipped onto the table surface 13 of the frame, and the lower half of the opening groove of the original double semi-circular structure 16 becomes the position facing directly upward after being flipped 180 degrees. Another group of double semi-circular sorting devices without a power source also complete the 180-degree flip of the double semi-circular structure 16 driven by the bamboo strips 2. While the double semi-circular sorting device is flipped 180°, the clamping cylinder 10 with the jaws 11 released, together with the grasping propulsion cylinder 7 and the grasping propulsion cylinder mounting plate 8, retracts to the initial position, repeats the above action of grasping the bamboo strips 2, runs above the double semi-circular sorting device 5 again, and repeats placing the specified number of bamboo strips 2 into the lower half of the opening groove of the original double semi-circular structure 16. The above process completes the face-to-face (or back-to-back) sorting process of a certain number of bamboo strips 2 that need to be bundled into a bundle, replacing manual sorting.

[0036] (3) As shown in Figure 4 , Figure 5 , the working process is executed by the roller pressing and conveying device arranged on the outer side of the double semi-circular sorting device 5: The first cylinder 17 starts to work, driving the U-shaped friction roller support 19, the friction roller 20, and the first motor 21 to move towards the bamboo strip 2. When the sides of the friction rollers 20 distributed on the left and right sides of the bamboo strip 2 are pressed against the stacked side of the bamboo strip 2, the first cylinder 17 stops advancing. At this time, the first motor 21 starts to work, and under the action of the friction roller 20, the bamboo strip 2 moves towards the roller auxiliary conveying mechanism.

[0037] (4) As shown in Figure 4 , when one end of the bamboo strip 2 to be bundled approaches the roller auxiliary conveying mechanism, one end of the stacked and bundled bamboo strip 2 passes through the lower end of the first upper pressure roller 24, and then continues to move under the action of the roller pressing and conveying device. When one end of the bamboo strip 2 just passes through the gap formed by the two side pressure rollers 25 in the roller auxiliary conveying device, the push rod of the second cylinder 23 starts to work, pushing the side pressure roller 25, the side pressure roller support 27, and the second motor 28 to move together towards the just-transported stacked and bundled bamboo strip 2 to be tied, and further pressing and stacking through the side pressure roller 25. At this time, the second motor 28 starts to work, continuing to assist in driving the stacked and bundled bamboo strip 2 to be tied towards the bundling machine 29 and passing through the second upper pressure roller 24.

[0038] (5) When the bamboo strip 2 to be bundled is tightly pressed and assisted by the second upper pressure roller 24 and conveyed out, the automatic bundling of the bundling machine 29 starts to work, first automatically bundling the head end of the bamboo strip 2 to be bundled. Then, when the bamboo strip 2 to be bundled continues to be transported for a certain distance, automatic bundling is performed again until the bamboo strip 2 to be bundled is completely bundled. During this process, one end of the bundled bamboo strip 2 is transported onto the conveyor belt 30 and finally conveyed to a unified collection container. Embodiment 2

[0039] Different from Embodiment 1, in this embodiment, the double semi-circular sorting device uses a reduction gear pair as another power source. As shown in Figure 6a and 6b , it includes a fourth motor 42, a small gear 37, and a large gear 38. The main shaft of the fourth motor 42 is connected to the small gear, and the large gear 38 meshing with the small gear is connected to the semi-circular body end face. A sheet metal cover 36 is provided outside the fourth motor 42, the small gear 37, and the large gear 38. The fourth motor 42 is preferably a stepping motor.

[0040] In this embodiment, the gear combination is as shown in Figure 6bThe internal teeth of the large gear 38 shown mesh with the external teeth of the small gear 37. It is also possible to use the external teeth of the large gear to mesh with the external teeth of the small gear. In the figure, the large gear 38 uses a double semi-circular connecting ring 39 for connecting with the double semi-circular structure, and the internal teeth are located on the inner circumferential surface of the double semi-circular connecting ring 39. The fourth motor 42 drives the small gear 37 to drive the large gear 38 to perform a 180-degree flipping action.
