Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood processing technology, and specifically to a device for removing the inner nodes of bamboo tubes. Background Technology

[0002] Bamboo and wood products are made from bamboo. The process usually involves first cutting the whole bamboo into bamboo tubes, then splitting the bamboo tubes into bamboo strips, and finally processing the bamboo strips into bamboo and wood products.

[0003] Chinese utility model patent document CN212736415U discloses a precise and efficient bamboo splitting device. By pushing bamboo tubes into a splitting blade, the bamboo tubes are transformed into bamboo strips. Because the bamboo tubes contain nodes, and the bamboo strips also contain nodes, this increases the processing difficulty and equipment failure rate in subsequent steps, such as rough planing, feeding, and wire drawing of the bamboo strips.

[0004] Therefore, before the bamboo splitting process, it is necessary to remove the inner nodes of the bamboo tube. After the bamboo nodes inside the bamboo tube are removed, the bamboo splitting device will produce bamboo strips with few or no bamboo nodes, thus preventing bamboo strips with bamboo nodes from entering the next process. However, manual removal of bamboo nodes is inefficient. Therefore, there is an urgent need in this technical field for a bamboo tube inner node removal device. Utility Model Content

Detailed Implementation

[0026] This utility model provides a device for removing the inner nodes of bamboo tubes. The overall technical concept is as follows: First, bamboo tubes are placed on the support trough of the bamboo tube loading and unloading mechanism for loading. Then, the first and second conical plates of the conical plate centering swing mechanism move towards the center and close, limiting the left end of the bamboo tube. The conical block of the conical mouth centering displacement mechanism moves to the left, and the conical mouth of the conical block limits the right end of the bamboo tube. The conical plate centering swing mechanism and the conical mouth centering displacement mechanism also clamp the bamboo tube, causing the bamboo tube to move on the conical surfaces at both ends for centering. The inner section removal push mechanism moves the inner section removal head towards the bamboo tube. After passing through the insertion port of the conical block, the inner section removal head is inserted into the bamboo tube to remove the inner section. The inner section removal head then exits from the bamboo tube, the first and second conical plates of the conical plate centering swing mechanism separate, and the conical block of the conical mouth centering displacement mechanism moves to the right and disengages from the bamboo tube. The support trough of the bamboo tube loading and unloading mechanism unloads the bamboo tube by swinging.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

The insertion port 412 communicates with the conical opening 411. The conical block 41 is fixedly connected to the bottom of the second base 42, and the second slider 43 is fixedly connected to the top of the second base 42.

The first conical plate 51 is swing-connected to the first horizontal beam 11, and the second conical plate 52 is swing-connected to the second horizontal beam 12.

[0030] The beneficial effects or advantages of this utility model are as follows: The device of this utility model is located in the pre-process of the bamboo splitting device and is an auxiliary process device in the automated bamboo processing production line. Its purpose is to remove the inner section of the bamboo tube 6. The bamboo tube 6 is first placed in the support groove of the bamboo tube loading and unloading mechanism 3 for loading. The conical mouth centering displacement mechanism 4 and the conical plate centering swing mechanism 5 then limit and center the two ends of the bamboo tube 6 respectively. The inner section removal head 21 of the inner section removal pushing mechanism 2 is inserted into the bamboo tube 6 through the insertion port 412 of the conical block 41 to open and remove the inner section of the bamboo tube 6. The conical mouth centering displacement mechanism 4 and the conical plate centering swing mechanism 5 are released from the limit, and finally the bamboo tube 6 is unloaded; the inner section of the bamboo tube 6 is removed quickly.

[0031] When the bamboo tube 6 is placed on the support trough plate 31, the support trough plate 31 supports the bamboo tube 6 upwards; the first conical plate 51 and the second conical plate 52 of the conical plate centering swing mechanism 5 move towards the center and close, forming a discharge port 57 between the closed first conical plate 51 and the second conical plate 52; the conical block 41 of the conical port centering displacement mechanism 4 moves to the left, and the right end of the bamboo tube 6 contacts the conical port 411 of the conical block 41. The conical block 41 pushes the bamboo tube 6, so that the left end of the bamboo tube 6 contacts the second conical plate 52. The left end of the bamboo tube 6 moves along the inclined surface of the second conical plate 52 and then reaches the discharge port 57. At the same time, the right end of the bamboo tube 6 moves along the inclined surface of the conical block 41 and then reaches the insertion position. When the first conical plate 51, the second conical plate 52, and the conical block 41 clamp the bamboo tube 6, the alignment of the bamboo tube 6 is completed. The inner section removal head 21 of the inner section removal pushing mechanism 2 is inserted into the right end of the bamboo tube 6 to remove the inner section. The inner section debris is discharged from the left end of the bamboo tube 6 and then reaches the discharge port 57 between the first conical plate 51 and the second conical plate 52.

[0032] The inner node removal pushing mechanism 2 is the core mechanism for removing the inner nodes of the bamboo tube. Driven by the first servo power source 25, the push shaft 22 pushes the inner node removal head 21. The inner node removal head 21 and the push shaft 22 are detachably connected, making it easy to replace the inner node removal head 21. The bamboo tube 6 with its inner nodes removed effectively reduces the resistance during the process of passing through the bamboo splitting disc, which helps to improve the bamboo splitting efficiency; resulting in bamboo strips with few or no nodes.

[0033] Furthermore, the frame 1 also includes a rack 14, which is fixedly connected to the first horizontal beam 11; The inner section removal pushing mechanism 2 further includes a first servo power source 25, a first gear 26, a first top side plate 27, a first front side plate 28, and a first rear side plate 29. The upper ends of the first front side plate 28 and the first rear side plate 29 are fixedly connected to the first top side plate 27, and the lower ends of the first front side plate 28 and the first rear side plate 29 are fixedly connected to the top of the first base 23. The first servo power source 25 is fixedly disposed on the upper surface of the first top side plate 27. The output shaft of the first servo power source 25 passes downward through the rotating hole of the first top side plate 27. The center of the first gear 26 is fixedly connected to the output shaft of the first servo power source 25. The first gear 26 meshes with the rack 14. The first horizontal beam 11 passes between the first front side plate 28 and the first rear side plate 29.

[0034] The beneficial effects of this technical solution are as follows: when the first servo power source 25 causes the first gear 26 to rotate in the forward direction, the first base 23 moves to the left along the rack 14; when the first servo power source 25 causes the first gear 26 to rotate in the reverse direction, the first base 23 moves to the right along the rack 14; the first servo power source 25 can be a servo motor, which has a fast response speed and helps the inner section removal head 21 to move quickly and accurately.

[0038] The beneficial effects of this technical solution are: by adjusting the bolt 213 to change the relative height between the adjusting plate 212 and the base plate 214, the height of the push shaft 22 and the inner section removal head 21 can be changed, which makes it easier to adjust the insertion port 412 of the aligned conical block 41.

[0040] The beneficial effects of this technical solution are: the extension and retraction movement of the loading and unloading cylinder 33 is converted into the back-and-forth swing of the material support trough 31, which facilitates the loading and unloading of bamboo tubes.

[0041] A hexagonal hole bearing 34, a hexagonal rod 35, and a hexagonal rod 35 fixing block are provided between the support trough plate 31 and the base 32. This is a preferred structure for the hinge connection.

[0042] Furthermore, the support trough plate 31 is a V-shaped trough plate.

[0043] The beneficial effects of this technical solution are: when the V-shaped opening of the V-shaped groove plate faces upward, it stably supports the bamboo tube; when the V-shaped opening of the V-shaped groove plate swings forward or backward, the bamboo tube slides along the inclined surface of the V-shape, which facilitates material feeding.

[0044] Furthermore, the conical mouth centering displacement mechanism 4 also includes a second servo power source 44, a second gear 45, a second top side plate 46, a second front side plate 47, and a second rear side plate 48. The upper ends of the second front side plate 47 and the second rear side plate 48 are fixedly connected to the second top side plate 46, and the lower ends of the second front side plate 47 and the second rear side plate 48 are fixedly connected to the top of the second base 42. The second servo power source 44 is fixedly disposed on the upper surface of the second top side plate 46. The output shaft of the second servo power source 44 passes downward through the rotating hole of the second top side plate 46. The center of the second gear 45 is fixedly connected to the output shaft of the second servo power source 44. The second gear 45 is meshed with the rack 14. The first horizontal beam 11 passes between the second front side plate 47 and the second rear side plate 48.

[0045] The beneficial effects of this technical solution are as follows: when the second servo power source 44 causes the second gear 45 to rotate in the forward direction, the second base 42 moves to the left along the rack 14; when the second servo power source 44 causes the second gear 45 to rotate in the reverse direction, the second base 42 moves to the right along the rack 14; the second servo power source 44 can be a servo motor, which has a fast response speed and helps the cone block 41 to move quickly and accurately.

[0046] The conical block 41 of the conical mouth centering displacement mechanism 4 is a welded body made of thin plate bent into shape. The function of the conical mouth centering displacement mechanism 4 is to center and limit the movement of the large diameter end of the bamboo tube, which is the left end of the bamboo tube, and to provide a stable force for the removal of the inner section.

[0047] Furthermore, the conical plate centering swing mechanism 5 also includes a first centering drive cylinder 53 and a second centering drive cylinder 54.

The cylinder body of the second centering drive cylinder 54 is fixedly connected to the lower surface of the second horizontal beam 12. The telescopic rod of the second centering drive cylinder 54 is hinged to the lower convex portion of the second conical plate 52.

[0048] The beneficial effects of this technical solution are as follows: the telescopic movement of the first centering drive cylinder 53 causes the first conical plate 51 to swing up and down, while the telescopic movement of the second centering drive cylinder 54 causes the second conical plate 52 to swing up and down, thereby realizing the convergence and divergence of the first conical plate 51 and the second conical plate 52. The structural space of the first horizontal beam 11 and the second horizontal beam 12 is utilized effectively, avoiding interference between the first centering drive cylinder 53 and the second centering drive cylinder 54 and the bamboo tube loading and unloading mechanism 3.

[0049] A first seated bearing 55 is provided between the first conical plate 51 and the first horizontal beam 11, and a second seated bearing 56 is provided between the second conical plate 52 and the second horizontal beam 12; this is a preferred structure for the hinge.

[0050] The function of the conical plate centering swing mechanism 5 is to cooperate with the conical mouth centering displacement mechanism 4 to limit the small end of the bamboo tube diameter, which is the right end of the bamboo tube, to prevent the bamboo tube from tilting during the removal of the inner section.

[0051] The working principle of the bamboo tube inner section removal device of this utility model is as follows: During feeding, the bamboo tube 6 slides into the short side of the V-shaped plate of the support trough plate 31. The first conical plate 51 and the second conical plate 52 of the conical plate centering swing mechanism 5 are closed. The second gear 45 of the conical mouth centering displacement mechanism 4 and the rack 14 on the frame 1 are driven. The conical block 41 pushes the bamboo tube to the left from the waiting position. The left and right ends of the bamboo tube are guided to be centered and limited by the conical plate centering swing mechanism 5 and the conical mouth centering displacement mechanism 4, respectively. After the centering and limiting of the bamboo tube 6 is completed, the first gear 26 of the inner section removal pushing mechanism 2 and the rack 14 on the frame 1 are driven. The inner section removal head 21 moves to the left from the initial position and inserts into the bamboo tube 6 to open and remove the inner section of the bamboo tube 6. After the inner section is removed, the conical plate centering swing mechanism 5 and the conical mouth centering displacement mechanism 4 release the centering limit at both ends of the bamboo tube respectively; at this time, the first conical plate 51 and the second conical plate 52 of the conical plate centering swing mechanism 5 open, the conical block 41 of the conical mouth centering displacement mechanism 4 returns to the initial position, the bamboo tube 6 returns to the support trough plate 31, the loading and unloading cylinders move to make the support trough plate 31 swing, and the bamboo tube 6 slides out from the long side of the V-shaped plate of the support trough plate 31 to complete the unloading.

[0052] This utility model provides a bamboo tube inner section removal device. The V-shaped structure of the material support trough 31 ensures good continuity of feeding and unloading actions. The conical mouth centering displacement mechanism 4 and the conical plate centering swing mechanism 5 provide good guiding and centering effects.
