Bamboo segment straightening and bamboo de-greening feeding mechanism

Abstract

In the bamboo segment straightening and bamboo green removal feeding mechanism structure involved in the present invention, since the straightening wheel group includes more than three guide wheel bodies distributed in a circumferential array, when the bamboo segment passes axially along the conveying direction between the three guide wheel bodies of the multiple straightening wheel groups, the common clamping effect of the three or more guide wheel bodies enables the bent part of the bamboo segment to be centered and straightened during the conveying process. The bamboo green removal mechanism is arranged between two of the straightening wheel groups. In the bamboo green bending mechanism, the bamboo green scraping blade is driven to rotate by the rotation of the rotating mechanism to perform circular cutting on the outer wall of the bamboo segment being conveyed, thereby removing the bamboo green from the outer wall of the bamboo segment. Since the bent bamboo segment can be fully straightened during the conveying process, the bamboo green scraping blade can completely and evenly cut off the bamboo green on the surface of the bamboo segment when the bamboo segment passes through the bamboo green removal mechanism, and there will be no problem of the bamboo green on the convex curved side being cut too deeply and the bamboo green on the concave curved side being cut too shallowly, resulting in the inability to completely remove the bamboo green.

Description

Technical Field

[0001] The invention relates to the technical field of bamboo segment processing, in particular to a bamboo segment straightening and bamboo green removal feeding mechanism. Background Art

[0002] Raw bamboo is unprocessed bamboo raw material. To be processed into bamboo products, raw bamboo needs to be sawn into fixed lengths to obtain bamboo segments, and then the surface of the bamboo segments is removed, the inner nodes are removed, and then the bamboo segments are equally divided into multiple bamboo pieces, and then the bamboo pieces are dried, carbonized and processed.

[0003] Chinese patent publication number CN109834783A discloses a system for efficiently utilizing bamboo segments to produce bamboo boards. It includes a bamboo segmentation system that sequentially arranges the cut bamboo segments, a bamboo segment diameter sorting device that sorts the segments by diameter, a round bamboo multi-piece profiling system that slices the segments, a bamboo strip milling system that slices the bamboo strips on all four sides, and a device for splicing the sliced bamboo strips into boards.

[0004] Referring to the above patent Figure 3 - Figure 6, the conveying mechanism includes three pairs of guide wheels installed on the slitting frame and support rollers connected to the slitting frame and installed below the conveying round bamboo. The three pairs of guide wheels are arranged in sequence from front to back and the guide wheels drive the round bamboo to be conveyed from front to back.

[0005] Referring to Figures 7 to 12 of the above patent, the bamboo segment outer section scraping device includes an annular cutter disc rotatably connected to the cutting machine frame, a power component that drives the annular cutter disc to rotate at high speed, and at least one group of outer section scraping components arranged on the inner circumferential wall of the annular cutter disc; the bamboo segment is fed in along the central axis of the annular cutter disc, and the power component drives the annular cutter disc to rotate at high speed. The front end of the bamboo segment first contacts the outer section conical wheel of the outer section guide roller, and the bamboo segment continues to be conveyed. The outer section telescopic seat overcomes the pressure of the outer section elastic part and slides outward until the outer section annular wheel of the outer section guide roller is tightly attached to the outer circumferential wall of the bamboo segment.

[0006] The solution of the above patent has the following problems:

[0007] When bamboo segments with large curvatures are transported, the curved parts of the bamboo segments bend downward due to the action of gravity. It is difficult to straighten the bamboo segments by relying on the guide wheels of the above-mentioned patented solution to limit them. Although support rollers are provided under the transported bamboo segments, the straightening effect is still very poor. The above-mentioned patented solution utilizes a high-speed rotating annular cutter disc to scrape off the green bamboo from the outer circumference of the bamboo segment. This structure has very high requirements on the straightness of the bamboo segment. For curved bamboo segments, it is easy to make it difficult to ensure the uniformity of removing the green bamboo from the outer circumference of the bamboo segment. For example, the green bamboo from the convex side of the curve is cut too deeply, and the green bamboo from the concave side of the curve is cut too shallowly, resulting in the inability to completely remove the green bamboo.

[0031] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0032] Please refer to Figures 1 to 5 The specific embodiment of the present invention relates to a bamboo segment straightening and bamboo green removal feeding mechanism, comprising:

[0033] A bamboo segment straightening guide mechanism 1, comprising two or more straightening wheel assemblies 11 distributed along a conveying direction; the straightening wheel assemblies 11 comprise three or more guide wheel bodies 111 distributed in a circumferential array;

[0034] The bamboo green removal mechanism 2 is located between two groups of straightening wheel groups 11. The bamboo green removal mechanism 2 includes a rotating mechanism 21 and a bamboo green scraping blade 22 connected to the rotating mechanism 21. The rotation axis of the rotating mechanism 21 coincides with the center of the circumferential array of the guide wheel body 111.

[0035] In the above structure, it should be noted that the rotating mechanism 21 can be a circular connecting seat, and the bamboo segment body 3 passes through the inner ring of the circular connecting seat. Its driving method can be to set a pulley or sprocket on the outer ring of the circular connecting seat, and set a motor on the upper part of the frame, and the motor is connected to the pulley. Through the motor and the belt, the circular connecting seat is driven to rotate. During the rotation process, the bamboo scraping blade 22 is driven to rotate together, contacting the outer wall of the bamboo segment body 3, so as to achieve the purpose of scraping off the bamboo green; the specific transmission method of the above rotating mechanism 21 is not shown in the figure, but through the above principle description, those skilled in the art can easily implement it.

[0036] In the above structure, since the straightening wheel group 11 includes more than three guide wheel bodies 111 distributed in a circular array, when the bamboo segment body 3 passes axially along the conveying direction between the three guide wheel bodies 111 of the multiple groups of straightening wheel groups 11, the bent part of the bamboo segment body 3 can be centered and straightened through the common clamping effect of the three or more guide wheel bodies 111 during the conveying process. The bamboo green removal mechanism 2 is arranged between two of the straightening wheel groups 11. In the bamboo green removal mechanism, the bamboo green scraping blade 22 is driven to rotate by the rotating mechanism 21 to perform circular cutting on the outer wall of the bamboo segment body 3 during conveying, and the bamboo green on the outer wall of the bamboo segment body 3 is removed. Since the bent bamboo segment body 3 can be fully straightened during the conveying process, the bamboo segment body 3 can be completely and evenly removed from the surface of the bamboo segment body 3 when the bamboo segment body 3 passes through the bamboo green removal mechanism 2, and there will be no problem that the bamboo green on the convex curved side is cut too deeply and the bamboo green on the concave curved side is cut too shallowly, resulting in the inability to completely remove the bamboo green.

[0037] As a preferred embodiment, each set of the straightening wheel assembly 11 includes a guide wheel adjustment mechanism 112, and the guide wheel adjustment mechanism 112 is used to synchronously adjust the radial displacement of each guide wheel body 111 relative to its circumferential array.

[0038] In the above structure, the straightening efficiency is further improved by adjusting each guide wheel body 111 to move radially synchronously.

[0039] As a preferred embodiment, refer to Figure 2The guide wheel adjustment mechanism 112 includes a first movable seat 1121 that moves radially along the circumferential array. The guide wheel body 111 is rotatably connected to the first movable seat 1121. Two sides of the first movable seat 1121 are provided with mutually symmetrical first racks 1122. Two adjacent first movable seats 1121 are connected with two first transmission gears 1123 and second transmission gears 1124 with the same diameter. The first rack 1122 is meshed with the first transmission gear 1123, and the second transmission gear 1124 is meshed with the other first movable seat. The first rack 1122 on one side of the moving seat 1121 is meshed, the first transmission gear 1123 and the second transmission gear 1124 have the same diameter, the distance between the axis of the first transmission gear 1123 and the axis of the circular array is equal to the distance between the axis of the second transmission gear 1124 and the axis of the circular array, and the guide wheel adjustment mechanism 112 also includes a first driving member, which is used to drive any first moving seat 1121 to move or to drive any first transmission gear 1123 to rotate or to drive any second transmission gear 1124 to rotate.

[0040] Preferably, the first transmission gear 1123 and the second transmission gear 1124 are both sector gears. Figure 2 It can be seen that since the rotation amplitude of the first transmission gear 1123 and the second transmission gear 1124 is small, they are designed in the shape of sector gears, which can save the accommodation space of the transmission components.

[0041] In the above structure, the first driving member Figure 2 Although not shown, the actual first driving member can be implemented in a variety of ways. For example, by driving the first transmission gear 1123 or the second transmission gear 1124 to rotate, a motor can be connected to one of the first transmission gears 1123 or the second transmission gear 1124, and by controlling the forward and reverse rotation of the first transmission gear 1123 or the second transmission gear 1124, multiple first movable seats 1121 can be simultaneously driven to move synchronously. For another example, by driving one of the first movable seats 1121 to move, the first transmission gear 1123 and the second transmission gear 1124 can be used to drive multiple first movable seats 1121 to move synchronously, thereby achieving the purpose of synchronous displacement adjustment of multiple guide wheel bodies 111.

[0042] As a preferred embodiment, the circumferential surface of the guide wheel body 111 is an arc surface with a concave center.

[0043] In the above structure, refer to Figure 2 as well as Figure 3The circumferential surface of the guide wheel body 111 is an arc surface with a concave middle part. This design can increase the contact area between the guide wheel body 111 and the outer circumferential surface of the bamboo segment body 3, ensure the stability of the centering clamping of the guide wheel body 111 on the bamboo segment body 3, and thus achieve better centering and straightening purposes.

[0044] As a preferred embodiment, the number of the straightening wheel groups 11 is 4, and the bamboo green removal mechanism 2 is arranged between the second group and the third group distributed along the conveying direction.

[0045] In the above structure, refer to Figure 1 As a preferred embodiment, the spacing between the second and third groups of straightening wheel groups 11 is smaller than the spacing between other groups, and the bamboo green removal mechanism 2 is arranged between the second and third groups distributed along the conveying direction, that is, the straightening wheel groups 11 are arranged at a very close distance in front and behind the conveying direction of the bamboo green removal mechanism 2. This structure ensures that the bent bamboo segment body 3 is straightened when passing through the bamboo green removal mechanism 2, further ensuring the uniformity of the bamboo green scraping of the bamboo segment body 3.

[0046] As a preferred embodiment, the bamboo green removal mechanism 2 includes two or more second movable seats 23 distributed in a circular array on the rotating mechanism 21. The movement direction of the second movable seats 23 is the radial direction of the circular array. The bamboo green scraping blade 22 is connected to the end of the second movable seat 23 facing the axis of the circular array. The mechanism also includes an elastic member, one end of which is connected to the rotating mechanism 21 and the other end is connected to the second movable seat 23. The elastic direction of the elastic member is the same as the movement direction of the second movable seat 23. In an actual mechanical structure, two or more guide rails distributed in a circular array can be provided on the rotating structure. The second movable seat 23 is slidably connected to the guide rails to limit the freedom of movement of the second movable seat 23.

[0047] In the above structure, refer to Figure 4 As a preferred embodiment, the bamboo scraping mechanism includes four second movable seats 23 distributed in a circular array on the rotating mechanism 21. The above elastic members can be springs. The springs are used to use their elasticity to separate the bamboo scraping blades 22 on the second movable seats 23 from the outer circumferential surface of the bamboo segment body 3 when the rotating mechanism 21 stops rotating.

[0048] More preferably, it further includes a bamboo segment outer wall guide roller 24, and the bamboo segment outer wall guide roller 24 is connected to one end of the second movable seat 23 facing the axis of the circumferential array.

[0049] In the above structure, refer to Figure 5The bamboo segment outer wall guide roller 24 is used to connect with the outer wall of the bamboo segment body 3 in a rolling manner when the rotating mechanism 21 drives the second movable seat 23 to rotate synchronously, thereby providing positioning for the bamboo green scraping blade 22 and further ensuring the uniformity of bamboo green scraping.

[0050] Further preferably, a second rack 25 is provided on one side of the second movable seat 23;

[0051] The centrifugal drive block 26 is rotatably connected to the rotating mechanism 21. The centrifugal drive block 26 is provided with sector teeth 261. The axis of the sector teeth 261 coincides with the rotation axis of the centrifugal drive block 26. A center of gravity deviation block 262 is provided on the side of the centrifugal drive block 26 away from the sector teeth 261.

[0052] The above structure is another invention point of the invention. Since the bamboo segment body 3 is fully straightened during the transportation process by the straightening wheel group 11, the bamboo segment body 3 is guaranteed to pass through the bamboo green removal mechanism 2 in a straight line. The present invention cleverly designs a second rack 25 on the second moving seat 23, and designs a centrifugal drive block 26 structure with a center of gravity deviation block 262 and a fan-shaped tooth. Please refer to Figure 4 By arranging a center of gravity deviation block 262 on the other side of the rotating shaft of the centrifugal drive block 26 away from the sector teeth 261, when the rotating mechanism 21 stops rotating, under the action of the elastic member, the second movable seat 23 moves radially outwardly of the bamboo segment body 3, so that the bamboo green scraping blade 22 does not contact the outer circumferential surface of the bamboo segment body 3. When the rotating mechanism 21 is controlled to rotate at a high speed, the center of gravity deviation block is thrown outward under the action of centrifugal force. At this time, the centrifugal drive block 26 rotates, and its sector teeth 261 drive the second rack 25 to move centripetally, so that the outer wall guide roller of the bamboo segment body 3 connected to the centrifugal drive block 26 and the bamboo green scraping blade 22 contact the outer circumferential surface of the bamboo segment body 3, thereby achieving the purpose of uniformly scraping the bamboo green on the outer circumference of the bamboo segment body 3.

[0053] It should be noted that during the high-speed rotation of the rotating mechanism, the centrifugal force of the centrifugal drive block's center of gravity deviation block is greater than the elastic force of the elastic member. Therefore, it can drive the second movable seat to overcome the elastic force 5 of the elastic member and move centripetally synchronously. In order to ensure the consistency of the centripetal movement distance of each second movable seat, it is necessary to ensure that the elasticity of each elastic member is consistent, the shape of each centrifugal drive member is consistent, and each second movable seat and centrifugal drive block is guaranteed to be distributed in a circular array.

[0054] The beneficial effect of the above structure is that, during the bamboo segment conveying process, the second movable seat will only move centripetally when the driving rotating mechanism rotates at high speed, so that the bamboo green scraping blade 0 connected to the second movable seat contacts the outer circumferential surface of the bamboo segment, and performs bamboo green scraping operation on the surface of the bamboo segment. If it is not necessary to remove the bamboo green from the bamboo segment, it is only necessary to control the rotating mechanism to stop rotating, so that the center of gravity deviation block stops the centrifugal action, and the second movable seat moves outward under the action of the elastic member, so that the bamboo green scraping blade does not contact the outer circumferential surface of the bamboo segment, so that the bamboo segment can be processed in two processing modes: removing the bamboo green or not removing the bamboo green.

[0055] 5 The above description is only an embodiment of the present invention and does not limit the scope of the invention.
