Abstract
Description
Technical Field
[0001] This utility model relates to the field of bamboo processing tools, and in particular to a bamboo partition removal tool. Background Technology
[0002] Bamboo is widely used in many fields due to its low shrinkage and high tensile and compressive strength along the grain. However, the structural characteristics of bamboo mean that it requires pre-treatment processes such as removing internal bamboo septa and cutting before it can be processed into bamboo products. Since bamboo septa are located inside the bamboo tube, external auxiliary tools are often needed to penetrate the bamboo tube during processing to break down or modify them, thus pre-treating the inside of the bamboo tube without damaging the main body. To improve processing efficiency and flexibility, many documents have disclosed solutions for auxiliary removal of bamboo septa and internal knots, and some bamboo septa removal tools are available on the market. However, most of the bamboo septa removal tools disclosed in the literature or available on the market have complex structures, which often leads to tool deformation and damage due to wear or the reaction force from the inner wall of the bamboo during application. In actual production, for some straight bamboo materials, due to their stable structure and straight internal length, the tools used for removing the internal septa of bamboo often do not require complex fitting structures. The key is to simplify the structure of the tools to make them more stable in terms of service life and durability while ensuring the removal effect. At the same time, how to adapt to the internal structure of bamboo and balance processing efficiency and effect is a research topic with positive practical significance and industrial application value. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to propose a bamboo partition removal tool that is simple in structure, convenient to use, has a long service life, and has a good bamboo partition cleaning effect.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0005] A bamboo septum removal tool, used to penetrate into a bamboo tube to remove the bamboo septum inside, comprising:
[0006] A tool holder, one end of which is equipped with a mounting shaft;
[0007] The connecting blocks are multiple and are sequentially and detachably sleeved on the mounting shaft of the tool holder;
[0008] The connecting block has multiple protruding teeth arranged in a ring array on its outer periphery, and these protruding teeth are used to break the bamboo septum.
[0009] The virtual diameter corresponding to the outer contour formed by the multiple connecting blocks and the multiple protruding teeth on them gradually increases along the direction approaching the tool holder.
[0010] As a possible implementation, further, the mounting shaft in this solution may be detachably provided with a clamping sleeve and a fixing bolt at the end away from the tool bar, the mounting shaft is provided with a threaded hole at the end away from the tool bar, and a limiting step is provided between the tool bar and the mounting shaft.
[0011] When multiple connecting blocks are sequentially sleeved on the mounting shaft of the tool holder, the clamping sleeve is sleeved on the end of the mounting shaft away from the tool holder, and the fixing bolt is screwed into the threaded hole to clamp and fix the clamping sleeve and the multiple connecting blocks sleeved on the mounting shaft between the fixing bolt and the limiting step.
[0012] As one possible implementation, further, the contours formed by the projection of the plurality of protrusions on the plurality of connecting blocks along the axial direction of the mounting shaft are at least partially misaligned.
[0013] As one possible implementation, furthermore, in this solution, spacers are provided between some adjacent connecting blocks among the plurality of connecting blocks.
[0014] As one possible implementation, the spacer in this solution is a spacer sleeve, which is sleeved on the mounting shaft.
[0015] As one possible implementation, the protruding teeth described in this solution are trapezoidal protruding teeth.
[0016] As one possible implementation, further, both the tool holder and the mounting shaft in this solution are round rod structures, and the mounting shaft is coaxially disposed at one end of the tool holder.
[0017] As a preferred implementation option, the plurality of connecting blocks in this solution preferably include: a first connecting block, a second connecting block, a third connecting block, and a fourth connecting block;
[0018] The virtual diameter corresponding to the outer contour formed by the first connecting block, the second connecting block, the third connecting block, and the fourth connecting block and the multiple protruding teeth thereon gradually increases along the direction approaching the tool holder.
[0019] As a preferred implementation option, the number of fourth connecting blocks in this solution is preferably three.
[0020] As a preferred implementation option, spacers are preferably provided between the first connecting block, the second connecting block, the third connecting block and the fourth connecting block in this solution.
[0021] Compared with the prior art, the present invention has the following advantages by adopting the above technical solution: The ingenious design of this solution involves mounting multiple connecting blocks on the mounting shaft. This structure makes the overall structure of the cutter frustum-shaped. When the cutter is mounted on the external drive component and penetrates the bamboo tube to remove the bamboo partitions, it first contacts the bamboo partitions through the fixing bolts at the front end of the cutter. Then, the external drive component pushes the bamboo partitions, causing them to break. As the cutter pushes in, the multiple connecting blocks gradually increase the extent of the bamboo partition breakage. Finally, the bamboo partitions are further pushed away from the inner wall of the bamboo tube by the protruding teeth on the outer periphery of the connecting blocks, thus achieving the removal of the bamboo partitions. This solution not only effectively cleans the bamboo partitions inside the bamboo tube, but also has a simple structure, making it easy to maintain and install. When installing the connecting blocks, operators can also adjust the misalignment angle between the protruding teeth on the connecting blocks and the protruding teeth of other connecting blocks by rotating the connecting blocks, so that the multiple protruding teeth on the multiple connecting blocks can thoroughly break the bamboo partitions when they penetrate the bamboo tube.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0030] Combination Figures 1 to 6 As shown in one embodiment, this invention provides a bamboo partition removal tool, which is used to penetrate into a bamboo tube 500 to remove the bamboo partitions 501 inside the bamboo tube 500, comprising:
[0031] The tool holder 100 has a mounting shaft 101 at one end;
[0032] Multiple connecting blocks 200 are sequentially and detachably sleeved on the mounting shaft 101 of the tool holder 100;
[0033] The connecting block 200 has a plurality of protruding teeth 201 arranged in a ring array on its outer peripheral side, and the plurality of protruding teeth 201 are used to break the bamboo partition 501.
[0034] In this design, in order to adapt to the internal structure of the bamboo tube 500 and to facilitate the removal of the bamboo partition 501, the virtual diameter corresponding to the outer contour formed by the multiple connecting blocks 200 and the multiple protruding teeth 201 on them gradually increases in the direction approaching the knife bar 100.
[0035] To facilitate the installation and adjustment of the posture of the multiple connecting blocks 200, as a possible implementation, the mounting shaft 101 in this solution may be further provided with a clamping sleeve 302 and a fixing bolt 301 at the end away from the tool bar 100. The mounting shaft 101 is provided with a threaded hole 103 at the end away from the tool bar 100, and a limiting step 102 is provided between the tool bar 100 and the mounting shaft 101.
[0036] When multiple connecting blocks 200 are sequentially sleeved on the mounting shaft 101 of the tool holder 100, the clamping sleeve 302 is sleeved on the end of the mounting shaft 101 away from the tool holder 100, and the fixing bolt 301 is screwed into the threaded hole 103 to clamp and fix the clamping sleeve 302 and the multiple connecting blocks 200 sleeved on the mounting shaft 101 between the fixing bolt 301 and the limiting step 102.
[0037] exist Figures 1 to 4 Based on what is shown, focus on combining Figure 5 , Figure 6As shown, in this scheme, multiple connecting blocks 200 are sleeved on the mounting shaft 101 to form an integral frustoconical cutter structure. This allows the cutter, after being loaded onto the external drive component 600, to first contact the bamboo partition 501 through the fixing bolt 301 at the front end of the cutter when it enters the bamboo tube 500 to remove the bamboo partition 501. Then, the bamboo partition 501 is broken by the advancement of the external drive component 600. As the cutter is pushed in, the multiple connecting blocks 200 gradually increase the extent of the breakage of the bamboo partition 501. Finally, the bamboo partition 501 is further pushed away from the inner wall of the bamboo tube 500 by the protruding teeth 201 on the outer periphery of the connecting block 200.
[0038] To improve the cleaning effect of bamboo separator 501, as a possible implementation, furthermore, the contours formed by the projection of the plurality of protrusions on the plurality of connecting blocks along the axial direction of the mounting shaft are at least partially misaligned (see...). Figure 4 ).
[0039] After the bamboo partition 501 is broken, it detaches from the inner wall of the bamboo tube 500, and the detached bamboo partition 501 temporarily accumulates in the bamboo tube 500 in the form of fragments. To prevent the fragments of the bamboo partition 501 from obstructing the tool from further breaking other bamboo partitions 501 within the bamboo tube 500, as a possible implementation, in this solution, spacers 400 are provided between some adjacent connecting blocks 200. The spacers 400 create a temporary storage space between adjacent connecting blocks 200, and some fragments of the bamboo partition 501 fall into the temporary storage space, preventing the tool from getting stuck in the bamboo tube 500 when it is being pushed forward. As another possible implementation, the spacers 400 in this solution are spacer sleeves, which are fitted onto the mounting shaft 101.
[0040] In terms of the structural form of the convex tooth 201, as a possible implementation, the convex tooth described in this solution is a trapezoidal convex tooth.
[0041] In addition, as a possible implementation, both the tool holder 100 and the mounting shaft 101 in this solution are round rod structures, and the mounting shaft 101 is coaxially disposed at one end of the tool holder 100.
[0042] In a specific implementation of the connecting block 200, as a preferred implementation option, the multiple connecting blocks 200 in this solution preferably include: a first connecting block 200a, a second connecting block 200b, a third connecting block 200c, and a fourth connecting block 200d;
[0043] The virtual diameter corresponding to the outer contour formed by the first connecting block 200a, the second connecting block 200b, the third connecting block 200c, and the fourth connecting block 200d and the multiple protruding teeth 200 (201a, 201b, 201c, 201d) on them gradually increases along the direction approaching the tool holder.
[0044] In this embodiment, as a preferred implementation option, the number of the fourth connecting blocks 200d is preferably three.
[0045] Regarding the spacer 400, as a preferred implementation option, it is preferred that the first connecting block 200a, the second connecting block 200b, the third connecting block 200c and the fourth connecting block 200d are all provided with spacers 400.
[0046] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model.
