Sliders 40 are fixedly installed on both sides of the lower plane of the propulsion cylinder mounting plate 8. The inner holes of the sliders 40 pass through the guide rod 6, so that the propulsion cylinder mounting plate 8 together with the grasping propulsion cylinders 7 fixed thereon can move back and forth along the guide rod 6.

[0027] Combined with Figure 3 、 Figure 4 As shown, the three-piece sorting device includes a power source, two U-shaped groove bodies 5, six pieces 14, and six micro-cylinders 16. Three piece-embedded grooves are opened on one inner wall of the U-shaped groove 51 of the U-shaped groove body 5. The ejector rods of the three micro-cylinders 16 arranged outside the U-shaped groove 51 extend into the piece-embedded grooves 15 and are respectively connected to the three pieces 14. The U-shaped grooves 51 of the two U-shaped groove bodies are arranged opposite to each other and can rotate. The power source drives one of the U-shaped groove bodies to flip. A channel 52 for pushing the bamboo strips 2 through is opened through the bottom of the U-shaped groove 51 of the other U-shaped groove body. The piece 14 is preferably made of a thin steel piece. The U-shaped groove body 5 is installed on the support 20 through a rotating shaft, and the support 20 is installed on the frame 13.

[0028] Preferably, the power source of this embodiment includes a driving motor 18, a coupling 19, and a motor base 17. The driving motor 18 is installed on the frame 13 through the motor base 17. The driving motor 18, the coupling 19, and the rotating shaft of one of the U-shaped groove bodies 5 are connected in sequence. The driving motor is preferably a stepping motor.

[0029] Specifically, the U-shaped groove body 5 of this embodiment adopts a design in which one side of the body is thicker than the other side. Three retaining pieces 14, one U-shaped groove body 5, and three micro-cylinders 16 form a combination. The three micro-cylinders 16 are installed at intervals on the outer side of the thick body on one side of the U-shaped groove body 5. The three retaining pieces 14 are respectively connected to the push rods of the three micro-cylinders 16, and the three retaining pieces 14 are respectively hidden in the retaining piece embedded grooves 15. One end of the thick body on the non-opening side of the U-shaped groove body 5 is installed on the support 20 through a rotating shaft, and the rotating shaft is connected to the driving motor 18 through a coupling 19. The driving motor 18 is installed on the frame body 13 through a motor base 17. One side of the thick body of the other U-shaped groove body 5 is installed on another support 20 through a rotating shaft, and the bottom of the U-shaped groove of this U-shaped groove body 5 is hollow (as shown in the first figure in Figure 3 ), and this hollow channel 52 is for realizing the conveying of the stacked bamboo strips 2.

[0030] Combined with 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. Each set of roller pressing and conveying devices respectively includes a friction roller 21 arranged longitudinally, a first cylinder 24, a first motor 22, a cylinder support 23, and a U-shaped friction roller support 25. Among them, the first cylinder 24 is fixedly installed on the cylinder support 23. The push rod head end of the first cylinder 24 is fixedly installed with a U-shaped friction roller support 25. The open end of the U-shaped friction roller support 25 is installed with a friction roller 21 arranged longitudinally. A first motor 22 is also installed and fixed on the U-shaped friction roller support 25. The first motor 22 can drive the friction roller 20 to rotate. The U-shaped friction roller support 25 together with the friction roller 21 and the first motor 22 can make a translational movement through the push rod of the first cylinder 24.

[0031] Combined with Figure 4 As shown, the roller auxiliary conveying mechanism of this embodiment mainly consists of two upper pressing rollers 28, four upper pressing roller supports 26, two side pressing rollers 29, a second cylinder 27, two cylinder seats 30, two side pressing roller supports 27, and two second motors 32, etc. Among them, the two side pressing rollers 29 are respectively installed in the two side pressing roller supports 27. The rotational power of the two side pressing rollers 29 comes from the two second motors 32 installed on the two side pressing roller supports 27. The whole set consisting of the side pressing roller 29, the side pressing roller support 27, and the second motor 32 can be pushed and translated together by the push rod of the second cylinder 27. The two upper pressing rollers 28 are respectively installed in the front and rear positions of the side pressing rollers 29. Each single upper pressing roller 28 is installed and fixed on the frame body 12 through two upper pressing roller supports 26. The second cylinder 27 is installed on the cylinder seat 30.

[0032] Combined with Figure 4As shown, the bundling machine 33 is located on one side near the output end of the roller auxiliary conveying mechanism, and the conveyor belt 34 is located on the other side of the bundling machine 33. The materials are conveyed to the bundling machine 33 through the roller auxiliary conveying mechanism for bundling, and then transmitted to the storage container through the conveyor belt 34.

[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 combination device starts to perform the first step of work: The stroke advancing cylinder 9 starts to work, pushing the advancing cylinder mounting plate 8 together with the two grasping advancing cylinders 7 to move along the guide rod 6 towards the bamboo strip collecting mechanism. When the grasping advancing cylinder 7 reaches above the bamboo strip collecting mechanism, the grasping advancing 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 advancing cylinder 9 continues to perform the second stroke advancing action, pushing the advancing cylinder mounting plate 8, the grasping advancing cylinder 7, the clamping cylinder 10, and the grasped bamboo strips 2 to run above the three-piece sorting device. At this time, the grasping advancing cylinder 7 works, driving the push rod to drive the clamping cylinder 10 to approach the inner slot of the middle piece of the double semi-circular structure 16. When reaching the specified position, the jaws 11 are released, and the specified number of bamboo strips 2 just fall into the inner slot of the middle piece of the double semi-circular structure 16 and are blocked in the upper half of the inner slot of the piece by the piece 15. The specified number of bamboo strips 2 just fall into the inner slot of the middle piece of the U-shaped groove body 15, as Figure 3 shown. Before the bamboo strips 2 fall into the inner slot of the middle piece of the U-shaped groove body 15, the middle one of the three micro-cylinders 16 located on the U-shaped groove body 15 works, pushing the piece 14 to block the middle position of the inner slot of the piece of the U-shaped groove body 15. When all the specified number of bamboo strips 2 grasped for the first time enter the inner slot of the piece of the U-shaped groove body 15, the first micro-cylinder 16 in the upper half works, pushing the piece 14 to block the upper half position of the inner slot of the piece of the U-shaped groove body 15. At this time, the specified number of bamboo strips 2 grasped for the first time are blocked in the middle by the upper and lower two pieces 14.

[0035] (2) As Figure 3 、 Figure 4As shown, repeat the grasping action in the first step. After grasping the specified number of bamboo strips 2 in the second group, convey them above the retaining piece embedded groove of the U-shaped groove body 15. Meanwhile, the U-shaped groove body 15 rotates 180 degrees driven by the drive motor 18, making the retaining piece embedded groove of the U-shaped groove body 15, which was originally at the lower end, face directly upward. Release the clamping jaw 11, put the specified number of bamboo strips 2 in the second group into the retaining piece embedded groove of the U-shaped groove body 15, and make the last micro cylinder 16 work to push the retaining piece 14 to block the lower half part (which is upward at this time) of the retaining piece embedded groove of the U-shaped groove body 15. The above process is carried out in two grabs before and after, completing 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 Figure 4 , Figure 5 shown, the working process is executed by the roller pressing and conveying device arranged on the outer side of the three retaining piece sorting device 5: The first cylinder 24 starts to work, driving the U-shaped friction wheel support 25, the friction roller 21, and the first motor 22 to move towards the bamboo strip 2. When the sides of the friction rollers 21 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 24 stops the pushing action. At this time, the motor A (22) starts to work, and under the action of the friction roller 21, the bamboo strip 2 moves towards the roller auxiliary conveying mechanism.

[0037] (4) As Figure 5 shown, 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 strips 2 to be tied passes through the lower end of the first upper pressing roller 28, 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 pressing rollers 29 in the roller auxiliary conveying mechanism, the push rod of the second cylinder 27 starts to work to push the side pressing roller 29, the side pressing wheel support 31, and the second motor 32 to move together towards the just-conveyed stacked and bundled bamboo strips 2 to be tied, and further tighten and stack them through the side pressing roller 29. At this time, the second motor 32 starts to work, continuing to assist in driving the stacked and bundled bamboo strips 2 to be tied towards the bundling machine 33 and passing through the second upper pressing roller 28.

[0038] (5) When the bamboo strip 2 to be bundled is tightly pressed and assisted in being conveyed out by the second upper pressing roller 28, the automatic bundling of the bundling machine 33 starts to work, and the head end of the bamboo strip 2 to be bundled is first automatically bundled. Then, when the bamboo strip 2 to be bundled continues to be conveyed for a certain distance, automatic bundling is performed again until the bamboo strip 2 to be bundled is completely bundled. At the same time during this process, one end of the bundled bamboo strip 2 is conveyed onto the conveyor belt 34 and finally conveyed into a unified collection container. Note that the above is only the preferred embodiment of the present invention and the applied technical principles. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, it can also include more other equivalent embodiments, and the scope of the present invention is determined by the scope of the appended claims.
