[0040] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0041] Please refer to Figures 1 to 4 , the utility model provides a bamboo chip adaptive material taking machine, comprising a lifting mechanism 1 and a material taking mechanism 2;

[0042] The material taking mechanism 2 is installed on the lifting end of the lifting mechanism 1, and the lifting mechanism 1 includes a single-axis cylinder 11, a housing 12, a connecting belt 17, a guide wheel 16, a pressure wheel 15, a tensioning mandrel 14, a spring box 13 and a spiral spring;

[0043] The housing 12 is fixed on the piston rod of the uniaxial cylinder 11;

[0044] The tensioning mandrel 14 is installed in the housing 12, and one end of the tensioning mandrel 14 extends outside the housing 12 and is connected to the inner ring of the spiral spring;

[0045] The outer ring of the spiral spring is fixed on the spring box 13;

[0046] The spring box 13 is fixedly arranged on one side of the outer wall of the housing 12;

[0047] The guide wheel 16 is mounted on the tensioning mandrel 14;

[0048] The connecting belt 17 is installed on the guide wheel 16, one end of the connecting belt 17 is fixed, and the other end of the connecting belt 17 is connected to the material taking mechanism 2;

[0049] The pressing wheel 15 is rotatably mounted in the housing 12 and is located above the guide wheel to restrict the connecting belt 17 on the guide wheel;

[0050] When in use, the piston rod of the single-axis cylinder 11 moves to the lowest position, and the material-retrieving mechanism 2 moves downward until it contacts the stacked bamboo pieces and is supported by the stacked bamboo pieces. Therefore, although the cylinder piston rod continues to move downward, the material-retrieving mechanism 2 has automatically stopped moving downward, and the stacked bamboo pieces are clamped by the material-retrieving mechanism 2, and then cooperate with the moving mechanism 3 to realize adaptive material retrieving of bamboo pieces stacked at different heights. When the material-retrieving mechanism 2 starts to fall to the bottom and touches the top of the stacked bamboo pieces, both sides of the connecting belt 17 are in a taut state. When the piston of the single-axis cylinder 11 drops to the bottom, the connecting belt 17 is Both sides will be in a relaxed state. At this time, the piston of the single-axis cylinder 11 will be at risk of spinning. In the present application, the preload force of the volute spring is transmitted to the guide wheel 16 through the tensioning core shaft 14. When one side of the connecting belt 17 connected to the feeding mechanism 2 is relaxed, it will drive the guide wheel 16 to rotate in the opposite direction, and the connecting belt 17 connected to one side of the feeding mechanism 2 will be retracted into the other side. The reaction force of the taut connecting belt 17 connected to one side of the feeding mechanism 2 can prevent the piston rod from spinning. Therefore, the connecting belt 17 on one side of the feeding mechanism 2 can always remain in a tensioned state, avoiding the problem of the connecting belt 17 being entangled.

[0051] In this embodiment, the material taking mechanism 2 includes a mounting plate 26, a connecting plate 27, a slider 23, a guide rail 22, a track plate 21, a clamping claw 25 and a three-axis cylinder 24;

[0052] The guide rail 22 is installed on the back of the track plate 21, and the bottom of the track plate 21 is connected to the free end of the connecting belt 17 through a connecting plate 27;

[0053] The slider 23 is slidably mounted on the guide rail 22 and fixed on the mounting plate 26;

[0054] The mounting plate 26 is fixedly arranged;

[0055] The three-axis cylinder 24 is installed on the surface of the track plate 21;

[0056] The clamping jaw 25 is mounted on the piston rod of the three-axis cylinder 24. After the clamping jaw 25 contracts with the three-axis cylinder 24, the stacked bamboo pieces are fixed between the clamping jaw 25 and the track plate 21.

[0057] When in use, the lifting end of the lifting mechanism 1 can drive the track plate 21 to move up and down along the guide rail 22. When the bottom of the three-axis cylinder 24 contacts the surface of the stacked bamboo pieces, the three-axis cylinder 24 drives the clamp 25 to contract, and the stacked bamboo pieces are fixed between the clamp 25 and the track plate 21, thereby realizing the clamping process of the stacked bamboo pieces.

[0058] In this embodiment, a moving mechanism 3 is also included, and the moving mechanism 3 includes a moving rail 31 and a frame 32 that can move on the moving rail 31. The lifting mechanism 1 is installed on the frame 32. The lifting mechanism 1 is provided with two groups, which are fixed at both ends of the upper surface of the frame 32. The picking mechanism 2 is provided with two groups, which are relatively arranged on both sides of the frame 32 and connected to the corresponding lifting mechanism 1; the two groups of lifting mechanisms 1 cooperate with the picking mechanism 2 to realize the clamping of the two ends of the stacked bamboo pieces.

[0059] The working principle of the utility model is as follows:

[0060] When grabbing the bamboo strips, the piston rod of the single-axis cylinder 11 rises to the top, the three-axis cylinder 24 extends to open the clamp 25, and then the piston of the single-axis cylinder 11 retracts from the top state to the bottom, and the bottom of the three-axis cylinder 24 on the track plate 21 touches the top of the top bamboo strip, preventing the track plate 21 from continuing to descend. The track plate 21 stops the descending movement, but the piston of the single-axis cylinder 11 continues to descend to the bottom, so that both sides of the connecting belt 17 are in a relaxed state. At this time, the volute spring drives the tensioning core shaft 14 to rotate, so that the guide wheel 16 rotates and rolls the synchronous belt inward. The outer connecting belt 17 remains taut. Under the force of the tightened outer synchronous belt, the piston rod of the single-axis cylinder 11 can be prevented from spinning, thereby avoiding the problem of winding of the connecting belt 17.

[0061] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.

[0062] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
