Description

Technical Field

[0001] This invention relates to the field of bamboo processing technology, specifically to a device for removing inner and outer nodes of circular arc bamboo strips in equal arc and quantity. Background Technology

[0002] In the field of bamboo product processing, the removal of bamboo nodes is a crucial step. As a natural material, bamboo has interspersed nodes in its internal structure. These nodes not only affect the appearance of the bamboo but also limit the design freedom and application range of bamboo products. Therefore, effective treatment of bamboo nodes is necessary when making high-quality bamboo products.

[0003] Existing bamboo node removal techniques mainly employ two methods. The first method involves manual operation by workers who hold a knife in one hand, press it against the surface of the bamboo node on the curved bamboo strip, and rotate the bamboo with the other hand to cut off the node. Although this method seems simple and direct, the actual operation is complex and delicate. Because the position and shape of each bamboo node are different, workers need to concentrate highly and adjust the angle and force of the knife according to the specific situation. This not only increases the labor intensity but also raises the skill requirements for workers. In addition, manual operation is slow, especially when facing the demand for large-scale bamboo product processing, which leads to low work efficiency and increased production costs.

[0004] The second method is to use a specially designed bamboo joint polishing device. This type of device uses mechanical force to polish the inner and outer bamboo joints of the curved bamboo strips to remove the bamboo joints. Compared with manual operation, the bamboo joint polishing device can improve work efficiency and reduce labor intensity to a certain extent. However, the use of this device still depends on manual loading and unloading. That is, workers need to frequently put bamboo into the equipment and take out the processed finished product. This process is also time-consuming and labor-intensive.

[0005] Therefore, there is a need for a device that can automatically remove inner and outer bamboo nodes by removing them in equal quantities from arc-shaped bamboo strips. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a device for automatically removing inner and outer bamboo nodes from arc-shaped bamboo strips in equal arc and quantity.

There is a third space between the upper and lower conveying rollers for the circular bamboo strips to pass through.

[0013] Preferably, the support block is provided with a vertical adjustment groove; a first guide hole is provided on the support block at the top of the adjustment groove; An adjusting component is provided in the adjusting groove.

This prevents the bamboo joint from being "lifted up" due to its location within the first and second spaces, thus avoiding the inability to accurately remove the inner and outer bamboo joints within the first and second intervals, which would lead to the generation of waste products. Furthermore, the first upper clamp of the first clamp is fixedly positioned above the first interval when the first arc-shaped blade cuts, and the second lower clamp is mirror-fixed and positioned below the second interval when the second arc-shaped blade cuts.

Combined with the conveying assembly, automated operation can be achieved, ensuring accurate removal of both inner and outer bamboo joints. Attached Figure Description

[0020] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please refer to Figures 1 to 4 A device for removing inner and outer sections of a circular arc bamboo strip in equal arc and quantity includes an inner section removal component 1, an outer section removal component 2, and a conveying component 3. The inner section removal assembly 1 includes a first motor 11, a first arc-shaped blade 12, and two sets of first clamps 13. The first clamp 13 includes a first upper clamp, a first lower clamp, and a reciprocating component. The first upper clamp is fixedly installed, and the first lower clamp is located directly below the first upper clamp. The reciprocating component drives the first lower clamp to move vertically toward the first upper clamp. There is a first space between the first upper clamp and the first lower clamp for the arc-shaped bamboo strip to pass through. The two sets of first clamps 13 are mirror images of each other and have a first gap 14 between them. When cutting, the first arc-shaped blade 12 is located above the first gap 14, and the first motor 11 drives the first arc-shaped blade 12 to rotate. The outer section removal assembly 2 includes a second motor 21, a second arc-shaped blade 22, and a second clamp 23. The second clamp 23 includes a second upper clamp 231 and two second lower clamps 232. The two second lower clamps 232 are fixedly arranged below the second upper clamp 231, and there is a second gap 233 between the two second lower clamps 232. The second upper clamp 231 is an elastic clamp, and the second upper clamp 231 cooperates with the two second lower clamps 232. There is a second space between the second upper clamp 231 and the two second lower clamps 232. When the second arc-shaped blade 22 is cutting, it is located below the second gap 233, and the second motor 21 drives the rotation of the second arc-shaped blade 22. The conveying component 3 is used to sequentially convey the arc-shaped bamboo strips to the inner section removal component 1 and the outer section removal component 2 and send them out after processing; the arc-shaped bamboo strip includes a bamboo node part and a bamboo internode part, and the part of the arc-shaped bamboo strip between the two bamboo nodes is the bamboo internode part. The axial length of the first clamp 13 and the axial length of the second lower clamp 232 are less than the minimum length of the inter-bamboo section of the arc-shaped bamboo strip.

[0022] As can be seen from the above description, by ensuring that the axial length of the first clamp 13 and the axial length of the second lower clamp 232 are less than the minimum length of the inter-bamboo portion of the arc-shaped bamboo strip, it can be guaranteed that during processing, the inter-bamboo portion can be completely fitted with the length of the first clamp 13 and the corresponding first and second spaces of the second lower clamp 232. This avoids the bamboo joint being located in the first and second spaces, causing the arc-shaped bamboo strip to be "lifted up," which would prevent the inner and outer bamboo joints of the bamboo joint located in the first interval 14 and the second interval 233 from being accurately removed, thus resulting in the generation of waste products. Furthermore, the first upper clamp of the first clamp 13 is fixedly positioned above the first interval 14 when the first arc-shaped blade 12 is cutting, and the second lower clamp 232 is fixedly positioned in a mirror image and below the second interval 233 when the second arc-shaped blade 22 is cutting, so that the inner and outer bamboo joints of each bamboo joint can be removed quantitatively and equally. When the first arc-shaped blade 12 cuts, it is positioned above the first interval 14, which can remove the inner bamboo nodes. When the second arc-shaped blade 22 cuts, it is positioned above the second interval 233, which can remove the inner bamboo nodes in equal arc and amount. With the help of the conveying component 3, it can achieve automated operation and ensure accurate removal of inner and outer bamboo nodes.

[0023] Furthermore, when the conveying component 3 delivers the bamboo joint to the midpoint of the first interval 14, the conveying component 3 stops conveying, the reciprocating component moves upward to clamp the arc bamboo strip, and at the same time the first motor 11 drives the rotation of the first arc-shaped blade 12, the first arc-shaped blade 12 quantitatively removes the inner bamboo joint of the bamboo joint. When the conveying component 3 delivers the bamboo joint to the midpoint of the second interval 233, the conveying component 3 stops conveying, the second clamp 23 elastically clamps the arc-shaped bamboo strip, and at the same time the second motor 21 drives the rotation of the second arc-shaped blade 22, which quantitatively removes the outer bamboo joint of the bamboo joint.

[0024] As can be seen from the above description, by stopping the conveying component 3 when it delivers the bamboo joint to the midpoint between the first interval 14 and the second interval 233, and then proceeding with the cutting, it is possible to ensure that the amount and arc of each cut are equal.

[0025] Furthermore, there are multiple first arc-shaped blades 12, and the first motor 11 includes a first rotating shaft. The multiple first arc-shaped blades 12 are arranged in a circumferential array on the first rotating shaft. The center point of the plurality of first arc-shaped blades 12 is located directly above the midpoint of the first interval 14; The distance from the center point of the plurality of first arc-shaped blades 12 to the midpoint of the first interval 14 is equal to the distance from the inner surface of the inter-bamboo part of the arc-shaped bamboo strip to the center point of the plurality of first arc-shaped blades 12 when the inter-bamboo part is located at the midpoint of the first interval 14.

[0026] As can be seen from the above description, rotary milling can be achieved by using multiple first arc-shaped cutters 12, which improves the processing effect. Furthermore, since the center point of the multiple first arc-shaped cutters 12 is located directly above the first interval 14, the distance from the first arc-shaped cutter 12 to the inner bamboo node is fixed. Combined with the fact that the distance from the center point of the multiple first arc-shaped cutters 12 to the midpoint of the first interval 14 is equal to the distance from the inner surface of the bamboo internode when the bamboo internode of the arc-shaped bamboo strip is located at the midpoint of the first interval 14 to the center point of the multiple first arc-shaped cutters 12, it is possible to achieve a continuous and flat inner surface between the bamboo node and the bamboo internode, avoiding over-processing that turns the inner bamboo node into a groove.

[0027] Furthermore, there are multiple second arc-shaped blades 22, and the second motor 21 includes a second rotating shaft, with multiple second arc-shaped blades 22 arranged in a circumferential array on the second rotating shaft; The center point of the plurality of second arc-shaped blades 22 is located directly below the midpoint of the second interval 233; The distance from the center point of the arrangement of the plurality of second arc-shaped blades 22 to the midpoint of the second interval 233 is equal to the distance from the outer surface of the inter-bamboo part of the circular arc bamboo strip to the center point of the arrangement of the plurality of second arc-shaped blades 22 when the inter-bamboo part is located at the midpoint of the second interval 233.

[0028] As can be seen from the above description, rotary milling can be achieved by using multiple second arc-shaped cutters 22, improving the processing effect. Furthermore, since the center point of the multiple second arc-shaped cutters 22 is located directly below the second interval 233, the distance from the second arc-shaped cutter 22 to the outer bamboo node is fixed. Combined with the fact that the distance from the center point of the multiple second arc-shaped cutters 22 to the midpoint of the second interval 233 is equal to the distance from the outer surface of the bamboo internode when the bamboo internode of the arc-shaped bamboo strip is located at the midpoint of the second interval 233 to the center point of the multiple second arc-shaped cutters 22, it is possible to achieve a continuous and flat outer surface between the bamboo node and the bamboo internode, avoiding over-processing that would turn the outer bamboo node into a groove.

[0029] Furthermore, the conveying assembly 3 includes an upper conveying roller 31, a lower conveying roller 32, and two support blocks 33; The two support blocks 33 are arranged in parallel, and the upper conveying roller 31 and the lower conveying roller 32 are arranged vertically between the two support blocks 33.

[0030] Furthermore, the outer surface of the upper conveying roller 31 is an outwardly protruding arc protrusion, and the outer surface of the lower conveying roller 32 is an arc concave with the same curvature as the arc protrusion. Before the circular arc bamboo strip enters the device for removing inner and outer nodes in equal arc and amount, the inner nodes are initially removed and softened. There is a third space between the upper conveying roller 31 and the lower conveying roller 32 for the circular bamboo strip to pass through.

[0031] As described above, before the curved bamboo strips enter the device for removing inner and outer nodes in equal arc and quantity, the inner nodes need to be initially removed (not completely removed, but partially removed to facilitate transport). By softening, the bamboo strips can be shaped by the upper conveying roller 31 and the lower conveying roller 32. By using the upper and lower conveying rollers 32 with curved protrusions and concave depressions, combined with the initial removal of inner nodes from the curved bamboo strips, the curvature can be better adapted, achieving equal arc and quantity removal of inner and outer nodes, improving the efficiency of transport and the stability of the transport device, and preventing the inner nodes from being too large and causing vibration.

[0032] Furthermore, the support block 33 is provided with a vertical adjustment groove 34; the support block 33 at the top of the adjustment groove 34 is provided with a first guide hole 331; An adjusting component 35 is provided in the adjusting groove 34. The adjusting component 35 includes a slider 351, a first spring 352, and a first guide rod 353. The slider 351 is disposed in the adjusting groove 34. One end of the first guide rod 353 is fixed to the slider 351, and the other end passes through the first guide hole 331. The first spring 352 is sleeved on the first guide rod 353 between the slider 351 and the first guide hole 331, and the outer diameter of the first spring 352 is larger than the diameter of the first guide hole 331.

[0033] The upper conveying roller 31 is rotatably connected at both ends to the sliders 351 of the two support blocks 33.

[0034] As can be seen from the above description, by setting the adjustment component 35, it is possible to adapt the third space to arc-shaped bamboo strips of different thicknesses.

[0035] Furthermore, when the conveying component 3 is used to convey the arc-shaped bamboo strips to the inner section removal component 1 and the outer section removal component 2 in sequence, the direction in which the arc-shaped bamboo strips pass is the conveying direction 4; The second upper clamp 231 includes a fixed plate 2311, a middle adjustment module 2312, and two sets of side adjustment modules 2313; The fixed plate 2311 is provided with a plurality of second guide holes, which are arranged along the conveying direction 4; the fixed plate 23111 is provided with downwardly extending extension plates 23111 on both sides of the fixed plate 23111, and the extension plates 23111 are provided with a plurality of third guide holes. The central adjustment module 2312 includes a central adjustment block 23121, multiple second springs 23122, and multiple second guide rods 23123; The middle adjustment block 23121 is long and strip-shaped and is set below the fixed plate 2311 and above the second lower clamp 232 along the conveying direction 4. The cross-section of the middle adjustment block 23121 is a four-sided structure with a straight edge at the top, a convex arc edge at the bottom, and sloping edges on both sides. Multiple second guide rods 23123 are fixed on the top of the middle adjusting block 23121, and the second guide rods 23123 pass through the second guide holes; the second spring 23122 is sleeved on the second guide rods 23123 between the fixing plate 2311 and the middle adjusting block 23121, and the two ends of the second spring 23122 are respectively connected to the top of the middle adjusting block 23121 and the bottom of the fixing plate 2311; The two sets of side adjustment modules 2313 are mirror images of each other on both sides of the center adjustment module 2312; The side adjustment module 2313 includes a side adjustment block 23131, multiple connecting blocks 23132, multiple third springs 23133, and multiple third guide rods 23134. The side adjustment block 23131 is elongated and is positioned below the fixed plate 2311 and above the second lower clamp 232 along the conveying direction 4. The cross-section of the side adjustment block 23131 is an inverted triangular structure with a straight edge at the top, a sloping edge on one side facing the middle adjustment block 23121, and an arc edge on the other side. Multiple connecting blocks 23132 are connected to the top of the side adjusting block 23131. One end of the third guide rod 23134 is connected to the connecting block 23132, and the end passes through the third guide hole and extends out of the guide hole. The end of the guide rod is also provided with a limit block. The third spring 23133 is sleeved on the third guide rod 23134 between the limit block and the third guide hole. The two inclined sides of the central adjustment block 23121 have a third interval with the inclined sides of the two side adjustment blocks 23131.

[0036] As can be seen from the above description, by cooperating with the central adjusting block 23121 and the two side adjusting blocks 23131, and by combining the second spring 23122 and the third spring 23133 with the third interval, it is possible to elastically fix the arc bamboo strips of different thicknesses without the need for special clamps; after the outer bamboo nodes are removed, since it is elastically locked rather than locked, the conveying component 3 can send out the processed arc bamboo strips.

[0037] Furthermore, the second space is 5-10mm.

[0038] As can be seen from the above description, the second space is 5-10mm under the action of the central adjustment module 2312 and the two sets of side adjustment modules 2313, which can adapt to most rounded bamboo strips.

[0039] Furthermore, a chamfer 5 is provided on the lower surface of the first upper clamp on the side away from the first arc-shaped blade 12; A chamfer 5 is provided on the edge of the upper surface of the first upper fixture near the first arc-shaped blade 12; A chamfer 5 is provided on the side edge of the upper surface of the second lower clamp 232 away from the second arc-shaped blade 22; A chamfer 5 is provided on the lower surface of the second lower clamp 232 near the edge of the second arc-shaped blade 22.

[0040] As can be seen from the above description, by setting the chamfer 5, the chamfer 5 on the side of the fixture away from the arc-shaped knife facilitates material discharge and feeding; while setting the chamfer 5 on the side closer to the arc-shaped knife provides space for the arc-shaped knife, making the structure more compact.

[0041] Example 1 A device for removing inner and outer sections of circular arc bamboo strips in equal arc and quantity includes an inner section removal component 1, an outer section removal component 2, and a conveying component 3. The inner section removal assembly 1 includes a first motor 11, a first arc-shaped blade 12, and two sets of first clamps 13. The first clamp 13 includes a first upper clamp, a first lower clamp, and a reciprocating component. The first upper clamp is fixedly installed, and the first lower clamp is located directly below the first upper clamp. The reciprocating component drives the first lower clamp to move vertically toward the first upper clamp. There is a first space between the first upper clamp and the first lower clamp for the arc-shaped bamboo strip to pass through. The two sets of first clamps 13 are mirror images of each other and have a first gap 14 between them. When cutting, the first arc-shaped blade 12 is located above the first gap 14, and the first motor 11 drives the first arc-shaped blade 12 to rotate. The outer section removal assembly 2 includes a second motor 21, a second arc-shaped blade 22, and a second clamp 23. The second clamp 23 includes a second upper clamp 231 and two second lower clamps 232. The two second lower clamps 232 are fixedly arranged below the second upper clamp 231, and there is a second gap 233 between the two second lower clamps 232. The second upper clamp 231 is an elastic clamp, and the second upper clamp 231 cooperates with the two second lower clamps 232. There is a second space between the second upper clamp 231 and the two second lower clamps 232. When the second arc-shaped blade 22 is cutting, it is located below the second gap 233, and the second motor 21 drives the rotation of the second arc-shaped blade 22. The conveying component 3 is used to sequentially convey the arc-shaped bamboo strips to the inner section removal component 1 and the outer section removal component 2 and send them out after processing; the arc-shaped bamboo strip includes a bamboo node part and a bamboo internode part, and the part of the arc-shaped bamboo strip between the two bamboo nodes is the bamboo internode part. The axial length of the first clamp 13 and the axial length of the second lower clamp 232 are less than the minimum length of the inter-bamboo section of the arc-shaped bamboo strip.
