Abstract
Description
Technical Field
[0001] This utility model relates to the field of bamboo sawing machine technology, and in particular to the raw bamboo clamping and conveying mechanism of bamboo sawing machine. Background Technology
[0002] The raw bamboo is about 10 meters long and 15 centimeters in diameter. Before being used as raw material, it needs to be cut into sections. Chinese patent CN219748356U discloses a bamboo sawing machine, which includes a clamping and moving assembly to pull the raw bamboo out of the feed trough, facilitating the sawing mechanism to cut the bamboo at the designated cutting points. In this patent, the push rod of the clamping cylinder pushes the clamping wedge forward, and the wedge-shaped part of the clamping wedge opens the front end of the clamping claws, causing the clamping claws to rotate around two pins as fulcrums, thus clamping the raw bamboo. In this structure, since the clamping claws on both sides are driven by the same cylinder and clamping wedge, the two clamping claws are always symmetrical and synchronous. In this case, when clamping a raw bamboo with a certain degree of curvature, it is difficult for the end of the raw bamboo to be aligned with the middle of the two clamping claws. That is, the end of the raw bamboo will be slightly biased to one side. However, the two clamping claws always move synchronously and symmetrically. This can easily lead to the clamping claws not being able to fully clamp the end of the raw bamboo. When pulling out, it is easy to cause the clamping part to loosen or slip, making it difficult to accurately position the cutting position. Utility Model Content
[0003] The technical problem to be solved by this utility model is to improve the raw bamboo clamping and pulling mechanism of the bamboo sawing machine so that it can provide stable clamping when raw bamboo with a certain degree of curvature is pulled out of the feed trough.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] The raw bamboo clamping and conveying mechanism of the bamboo sawing machine includes:
[0006] A guide rail mechanism, wherein the guide rail mechanism extends along the X direction;
[0007] A movable seat, which is movably connected to a guide rail mechanism;
[0008] The first clamping mechanism includes a first clamping arm, a first rotating shaft, a first clamping bar, a first connecting rod, and a first telescopic cylinder. The first rotating shaft is fixedly connected to the X-axis end of the first clamping arm, and the first rotating shaft is pivotally connected to a first pivot point of a movable seat. One end of the first connecting rod is fixedly connected to the first rotating shaft. One end of the first telescopic cylinder is pivotally connected to a second pivot point of the movable seat, and the other end of the first telescopic cylinder is pivotally connected to the other end of the first connecting rod as a third pivot point. The first clamping bar is vertically connected to the X-axis end of the first clamping arm.
[0009] The second clamping mechanism is a mirror image of the first clamping mechanism.
[0010] Furthermore, in the raw bamboo clamping and conveying mechanism of the above-mentioned bamboo sawing machine, the guide rail mechanism includes two guide rails, and the outer side of the guide rails is provided with triangular prisms with their side edges facing outwards. The movable seat is connected to a guide wheel, and the circumferential surface of the guide wheel is provided with an annular groove that mates with the side edges of the triangular prisms.
[0011] Furthermore, in the raw bamboo clamping and conveying mechanism of the aforementioned bamboo sawing machine, a rack is provided on the inner side of one of the guide rails, a gear is rotatably connected to the moving seat, the gear meshes with the rack, and a drive motor connected to the gear transmission is provided on the moving seat.
[0012] Furthermore, in the raw bamboo clamping and conveying mechanism of the aforementioned bamboo sawing machine, the second pivot point is located on the X-direction side of the first pivot point, and the third pivot point is located on the outside of the first pivot point.
[0013] Furthermore, in the raw bamboo clamping and conveying mechanism of the aforementioned bamboo sawing machine, the inner side of the first clamping bar is provided with saw teeth.
[0014] The beneficial effects of this utility model are as follows: The first clamping mechanism and the second clamping mechanism are driven by independent telescopic cylinders. Through the pivotal connection of the connecting rod and the rotating shaft, the clamping force is stably transmitted to the corresponding clamping strips. The vertical clamping strips are used to clamp the raw bamboo. This structure can provide more stable clamping when the raw bamboo has a large curvature. Since the front storage trough limits the raw bamboo to a certain extent, when the clamping and pulling mechanism clamps the end of the raw bamboo, the end of the raw bamboo will deviate to one side or deviate downward to a certain extent due to its natural curvature. In this utility model, the stroke of the telescopic cylinder of the corresponding clamping mechanism can be adjusted according to the lateral offset position of the end of the raw bamboo to adapt to the lateral offset of the end of the raw bamboo. Since the raw bamboo is clamped by vertical clamping strips, it can be used to clamp raw bamboo with different curvature angles and diameters, effectively avoiding the slippage of the raw bamboo during the pulling process, which would reduce the accuracy of the cutting point.

[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0025] Please refer to Figure 1 as well as Figure 2 The specific embodiment of this utility model relates to a raw bamboo clamping and conveying mechanism for a bamboo sawing machine, comprising:
[0026] Guide rail mechanism 1, which extends along the X direction;
[0027] Movable seat 2, which is movably connected to guide rail mechanism 1;
[0028] The first clamping mechanism 3 includes a first clamping arm 31, a first rotating shaft 32, a first clamping bar 33, a first connecting rod 34, and a first telescopic cylinder 35. The first rotating shaft 32 is fixedly connected to the X-direction end of the first clamping arm 31. The first rotating shaft 32 is pivotally connected to the first pivot point 36 of the movable seat 2. One end of the first connecting rod 34 is fixedly connected to the first rotating shaft 32. One end of the first telescopic cylinder 35 is pivotally connected to the second pivot point 37 of the movable seat 2. The other end of the first telescopic cylinder 35 is pivotally connected to the other end of the first connecting rod 34 as a third pivot point 38. The first clamping bar 33 is vertically connected to the X-direction end of the first clamping arm 31.
[0029] The second clamping mechanism 4 is a mirror image of the first clamping mechanism 3.
[0030] In the above embodiments, the purpose of the raw bamboo clamping and conveying mechanism is to improve the structure of the clamping claw and moving platform based on the Chinese patent with authorization announcement number CN219748356U. In the solution of this utility model, the first clamping mechanism 3 and the second clamping mechanism 4 are driven by independent telescopic cylinders. Through the pivotal relationship of the connecting rod and the rotating shaft, the clamping force is stably transmitted to the corresponding clamping bar. The vertical clamping bar is used to clamp the raw bamboo. This structure can provide more stable clamping when the raw bamboo has a large curvature. Due to the front end... The storage trough provides certain limits for the raw bamboo. When the clamping and conveying mechanism clamps the end of the raw bamboo, the end of the raw bamboo will deviate to one side or downward due to its natural curvature. In this utility model, the stroke of the telescopic cylinder of the corresponding clamping mechanism can be adjusted according to the lateral offset position of the end of the raw bamboo to adapt to the lateral offset of the end of the raw bamboo. Since the raw bamboo is clamped by vertical clamping strips, it can be used to clamp raw bamboo with different bending angles and diameters, effectively avoiding slippage of the raw bamboo during the conveying process, which would reduce the accuracy of the cutting point.
[0031] In a preferred embodiment, the guide rail mechanism 1 includes two guide rails 11, and the outer side of the guide rails 11 is provided with triangular prism bars 12 with their side edges facing outward. The movable seat 2 is connected to a guide wheel 21, and the circumferential surface of the guide wheel 21 is provided with an annular groove 211 that cooperates with the side edge of the triangular prism bar 12.
[0032] In a preferred embodiment, a rack 13 is provided on the inner side of one of the guide rails 11, and a gear 22 is rotatably connected to the movable seat 2. The gear 22 meshes with the rack 13, and a drive motor 23 is provided on the movable seat 2 that is connected to the gear 22 for transmission.
[0033] In the above embodiments, the drive motor 23 drives the gear 22 to rotate, thereby driving the movable seat 2 to move along the guide rail mechanism 1 through the meshing of the gear 22 and the rack 13.
[0034] In a preferred embodiment, the second pivot point 37 is located on the X-direction side of the first pivot point 36, and the third pivot point 38 is located outside the first pivot point 36. This structure is more conducive to the telescopic cylinder transmitting the clamping force to the clamping bar part.
[0035] As a preferred embodiment, the inner side of the first clamping strip 33 is provided with serrations. By providing serrations, the clamping strip can further avoid slippage when clamping the raw bamboo, thereby ensuring the accuracy of the cutting point.
[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
