Bamboo segment fragments and inner node removal mechanism

Abstract

In the bamboo section fragmenting and inner node removing mechanism of the present invention, when the bamboo section passes through the main body of the bamboo section fragmenting mechanism, the bamboo section is fragmented into a plurality of equally divided bamboo slices by a plurality of sawing mechanisms arranged in a circumferential array. During the process of fragmenting into bamboo slices, the rotating shaft of the main body of the inner node removing mechanism rotates at a high speed, driving the node breaking drill bit to drill holes in the inner node of the bamboo section. After drilling, the inner node scraping mechanism contacts the side wall at the drilling position. Since the shape of the inner node scraping mechanism is tower-shaped, multiple groups of inner node scraping tools are arranged on the outside of the inner node scraping mechanism along the conveying direction, and the holes of the inner node are gradually milled and enlarged until the inner wall of the inner node is completely scraped flat. In the bamboo slice feeding mechanism, the interaction of the fixing part, the movable part, the feeding wheel and the elastic part enables the bamboo slices to better pass through the gap between the feeding wheel and the positioning sleeve, ensuring stable conveying. This enables the operations of bamboo section fragmenting and inner node removing to be completed simultaneously on one device, greatly improving the production efficiency.

[0055] The inner segment removal mechanism body 2 comprises a rotating shaft 21, a segment-breaking drill bit 22 and an inner segment-scraping mechanism 23, the axis of the rotating shaft 21 coincides with the axis of the circumferential array of the plurality of sawing mechanisms 14; the segment-breaking drill bit 22 is arranged at the end of the rotating shaft 21 away from the conveying direction of the bamboo segment; the inner segment-scraping mechanism 23 is arranged outside the rotating shaft 21, the inner segment-scraping mechanism 23 is located in front of the segment-breaking drill bit 22 relative to the conveying direction, the inner segment-scraping mechanism 23 is in the shape of a tower, and the outer portion of the inner segment-scraping mechanism 23 is provided with a plurality of groups of inner segment-scraping tools 231 along the conveying direction, and the distance from the outer portion of each group of inner segment-scraping tools 231 distributed along the conveying direction to the axis of the rotating shaft 21 increases successively;

[0056] A positioning sleeve 3, wherein the positioning sleeve 3 is sleeved on the outside of the rotating shaft 21, the positioning sleeve 3 is rotatably connected to the rotating shaft 21 via a bearing 4, and the starting end of the positioning sleeve 3 is located at the end of the inner section scraping mechanism 23;

[0057] The bamboo chip pressing and feeding mechanism 5 comprises a plurality of pressing and feeding mechanism monomers 51 distributed in a circular array, the axis of the circular array coincides with the axis of the rotating shaft 21, the bamboo chip pressing and feeding mechanism 5 is located at the starting end of the positioning sleeve 3, the pressing and feeding mechanism monomer 51 comprises a fixed portion 511, a movable portion 512, a pressing and feeding wheel 5121 and an elastic member 513, the number of the elastic members 513 is multiple, the number of the movable portions 512 is the same as the number of the elastic members 513, the pressing and feeding wheel 5121 is connected to the movable portion 512, the elastic member 513 is connected between the movable portion 512 and the fixed portion 511, the elastic direction of the elastic member 513 is the radial direction of the circular array, and the pressing and feeding wheel 5121 is used to press the bamboo chips broken out of the bamboo segment breaking mechanism body 1 against the outer circumferential surface of the positioning sleeve 3 and press them in the conveying direction.

[0058] In the above embodiment, when the bamboo segment passes through the bamboo segment breaking mechanism body 1, the bamboo segment is broken into a plurality of equally divided bamboo pieces by a plurality of sawing mechanisms 14 distributed in a circular array. In the process of breaking the bamboo pieces, the rotating shaft 21 of the inner segment removal mechanism body 2 is rotated at a high speed to drive the breaking drill 22 to drill holes in the inner segments of the bamboo segment. After drilling, the inner segment scraping mechanism 23 contacts the side wall of the drill hole. Since the inner segment scraping mechanism 23 is in a tower shape, a plurality of groups of inner segment scraping tools 231 are provided on the outside of the inner segment scraping mechanism 23 along the conveying direction. The distance from the outer extension of each group of inner segment scraping tools 231 distributed along the conveying direction to the axis of the rotating shaft 21 increases successively.

In the bamboo piece pressing mechanism 5, the interaction between the fixed part 511, the movable part 512, the pressing wheel 5121 and the elastic member 513 enables the pressing wheel 5121 to not only obtain stable transmission, but also have a certain elastic force in the radial direction of the conveying direction under the action of the elastic member 513, so that the bamboo pieces can better pass through the gap between the pressing wheel 5121 and the positioning sleeve 3, thereby ensuring stable conveying.

[0059] In summary, the above bamboo segment breaking and inner node removal mechanism can complete the bamboo segment breaking and inner node removal operations on one device at the same time, greatly improving production efficiency.

[0060] Among the above institutions, refer to Figure 10 A conical guide ring is also provided between two adjacent groups of inner section scraping cutters 231, which is used to smoothly transition the drilling holes of the bamboo inner section to the next group of inner section scraping cutters 231.

[0061] As an optional embodiment, the segment breaking drill bit 22 is located between the rotation axis of the saw blade 141 and the outer end in the conveying direction.

[0062] In the above embodiment, by setting the position of the above-mentioned node breaking drill bit 22, the breaking of the bamboo segment and the drilling of the inner node of the bamboo segment can be completed almost at the same time, which can further improve the processing stability and the production efficiency.

[0063] As an optional embodiment, it also includes a driving motor and a driving gear 6, the fixing portion 511 includes a first gear set 5111, the driving motor is drivingly connected to the driving gear 6, the first gear set 5111 includes a plurality of first gear monomers 51111 distributed in a circular array, both sides of each first gear monomer 51111 are respectively fixedly connected with a bevel gear 51112, and two adjacent first gear monomers 51111 are drivingly connected via the bevel gear 51112;

[0064] The movable portion 512 is provided with a second gear set, and the second gear set includes more than one second gear monomers 5122 meshing with each other, wherein one second gear monomer 5122 meshes with the first gear monomer 51111 , and one second gear monomer 5122 is connected to the pressing wheel 5121 .

[0065] In the above embodiment, only one driving motor and one driving gear 6 are needed to simultaneously drive a plurality of first gear units 51111 distributed in a circular array to rotate simultaneously, thereby driving each second gear set of the movable part 512 to rotate, and further driving each pressing wheel 5121 to rotate, so as to press and convey the bamboo strips along the conveying direction.

[0066] As an optional implementation, the central axis connecting line of the mutually meshing first gear monomer 51111 and the second gear monomer 5122 is the first connecting line, and the angle between the first connecting line and the elastic direction of the elastic member 513 is 75-90 degrees.

[0067] In the above implementation mode, refer to Figure 11 The angle between the line connecting the axis of the first gear monomer 51111 and the axis of the second gear monomer 5122 and the elastic direction is close to vertical. This structure enables the first gear and the second gear to always maintain a stable meshing state during the process of the elastic member 513 extending and retracting to drive the movable part 512 to move, thereby ensuring stable power transmission of the pressure wheel 5121.

[0068] As an optional implementation, the driving gear 6 and the first gear monomer 51111 are connected to each other via one or more transmission gears.

[0069] In the above implementation mode, refer to Figure 11 The driving gear 6 is connected to the first gear monomer 51111 through two transmission gears. This structure can ensure the stability of power transmission and make the transmission between the driving gear 6 and the first gear monomer 51111 form an angle, which can effectively avoid the movable part 512 and provide sufficient activity space for the movable part 512, which can effectively save space for mechanical equipment.

[0070] As an optional implementation, the number of the second gear units 5122 of each second gear set is three.

[0071] As an optional implementation, the main body 31 of the positioning sleeve 3 is in the shape of a circular cylinder, a conical transition section 32 is provided at the beginning of the positioning sleeve 3 , and the pressing wheel 5121 is located outside the transition section 32 .

[0072] In the above embodiments, when the bamboo strip is being conveyed and passes through the inner node scraping mechanism 23 of the tower shape, the inner side of the bamboo strip can smoothly transition to the outside of the main body 31 of the positioning sleeve 3 with a circular cylinder shape through the conical transition section 32, so that the bamboo strip can smoothly transition during the pressing process and avoid damage to the inner wall of the bamboo strip.

[0073] As an alternative embodiment, the main body 1 of the bamboo section fragmenting mechanism includes a fixing frame 11, a fixed connection seat 12, a movable connection seat 13, a first driving member 15 and a second driving member 16;

[0074] A through hole for the axial passage of the bamboo section is provided in the middle of the fixing frame 11;

[0075] The fixed connection seat 12 is fixedly connected to the fixing frame 11;

[0076] The movable connection seat 13 is movably connected to the fixing frame 11, and the moving direction of the movable connection seat 13 is to rotate around the axis of the through hole. A plurality of the movable connection seats 13 and the fixed connection seat 12 are arranged in a circumferential array with the center of the through hole as the center of the circle;

[0077] The sawing mechanism 14 includes a mounting seat 142 and a driving motor. The saw blade 141 is rotatably connected to the mounting seat 142. The driving motor is fixedly connected to the mounting seat 142, and the driving motor is in transmission connection with the saw blade 141 for driving the saw blade 141 to rotate;

[0078] The mounting seat 142 of one of the sawing mechanisms 14 is fixedly connected to the fixed connection seat 12;

[0079] The mounting seats 142 of more than one of the sawing mechanisms 14 are fixedly connected to the movable connection seat 13;

[0080] The mounting seats 142 of more than one of the sawing mechanisms 14 are movably connected to the movable connection seat 13, and the moving direction of the mounting seat 142 is the radial direction of the through hole;

[0081] The first driving member 15 is connected between the movable connection seat 13 and the mounting seat 142, and the first driving member 15 is used to drive the mounting seat 142 to move along the radial direction of the through hole;

[0082] The second driving member 16 is connected between the fixing frame 11 and the movable connection seat 13, and the second driving member 16 is used to drive the movable connection seat 13 to rotate around the axis of the through hole.

[0083] In the above embodiments, by providing a plurality of movable connection seats 13 and a fixed connection seat 12 on the fixed frame 11, the plurality of movable connection seats 13 and the fixed connection seat 12 are arranged in a circumferential array with the center of the through hole as the center of the circle. A sawing mechanism 14 is respectively connected to each movable connection seat 13 and the fixed connection seat 12. The driving motor drives the saw blade 141 to rotate at a high speed, and the bamboo segments conveyed through the through hole are equally divided into bamboo slices. Since the movable connection seat 13 can rotate a certain angle along the axis of the through hole, and the mounting seat 142 of some sawing mechanisms 14 is movably connected to the movable connection seat 13. When it is necessary to adjust the equal division quantity of the bamboo segment fragments, one or more sawing mechanisms 14 movably connected to the movable connection seat 13 can be controlled to move radially along the through hole, and then the other movable connection seats 13 are respectively rotated by corresponding predetermined angles, so as to achieve the purpose of adjusting the equal division quantity of the bamboo segment fragments. Since the method of fragmenting the bamboo segment by the high-speed rotation of the saw blade 141 has the advantages of good slicing flatness and high utilization rate of bamboo materials compared with the structure of the traditional stamping cutter head, the adjustable bamboo segment fragmenting mechanism involved in the present invention can simultaneously meet the requirements of good slicing flatness, high utilization rate of bamboo materials, and be applicable to fragmenting methods of various different equal division specifications.

[0084] As an alternative embodiment, the movable connection seats 13 movably connected to the mounting seat 142 and the movable connection seats 13 fixedly connected to the mounting seat 142 are distributed at intervals. Since the adjustment of the bamboo segment fragments is generally adjusted between 8 and 13 pieces, it is not necessary to adjust all the sawing mechanisms 14 radially along the center of the circumferential array. The above-mentioned distribution method of the movable connection seats 13 and the movable connection seats 13 fixedly connected to the mounting seat 142 can reduce the rotation stroke of each sawing mechanism 14 when adjusting the number of fragments.

[0085] As an alternative embodiment, the fixed frame 11 is provided with a cylindrical connection portion 121 coaxial with the through hole, and the movable connection seat 13 is provided with a collar 131 that rotates in cooperation with the outer wall of the cylindrical connection portion 121; so that the movable connection seat 13 can be rotatably connected to the fixed frame 11 along the axis of the circumferential array.

[0086] As an alternative embodiment, refer to Figure 8 , which shows a schematic diagram of the principle of the adjustable bamboo segment fragmenting mechanism. 13 groups of sawing mechanisms 14 are shown in the figure. Each circled number represents a sawing mechanism 14 respectively. Among them, the 7th sawing mechanism 14 is fixedly connected to the fixed connection seat 12, and its position cannot be adjusted. The other sawing mechanisms 14 are connected to the movable connection seats 13, and the first driving member 15 can rotate a certain angle along the center of the circumferential array. Among them, the 1st, 3rd, 5th, 1', 3', and 5' sawing mechanisms 14 are connected with the first driving member 15 and can move radially along the circumferential array;

[0087] Figure 8 Among them, the circled numbers in the inner circle represent the circumferential array of the saw blades 141 of 13 groups of sawing mechanisms 14 in a state for sawing the bamboo segments into 13 equal parts. The circled numbers in the outer circle represent that one group of No. 1' sawing mechanism 14 moves radially outward along the circumferential array driven by the first driving member 15. After separating from the circumferential array, the other 12 groups of sawing mechanisms 14 respectively rotate by a certain angle to reach the circumferential array distribution state of 12 equal parts, for the state of sawing the bamboo segments into 12 equal parts. Figure 8 Among them, the position of the No. 7 sawing mechanism 14 remains unchanged all the time. When the No. 1' sawing mechanism 14 is withdrawn, the sawing mechanisms 14 on both sides of the No. 7 sawing mechanism 14 respectively rotate by a certain angle driven by the second driving member 16. The No. 6' rotates counterclockwise by 2.31 degrees, the No. 6 rotates counterclockwise by 2.31 degrees, the No. 5' rotates counterclockwise by 4.62 degrees, the No. 5 rotates counterclockwise by 4.62 degrees, the No. 4' rotates counterclockwise by 6.92 degrees, the No. 4 rotates counterclockwise by 6.92 degrees, the No. 3' rotates counterclockwise by 9.23 degrees, the No. 3 rotates counterclockwise by 9.23 degrees, the No. 2' rotates counterclockwise by 11.54 degrees, the No. 2 rotates counterclockwise by 11.54 degrees, the No. 1' rotates clockwise by 1.15 degrees, and the No. 1 rotates clockwise by 13.85 degrees.

[0088] In the above embodiments, when changing from 13 equal parts to 12 equal parts, the rotation angle of each sawing mechanism 14 is less than 15 degrees, the stroke requirement for the second driving member 16 is small and it is easy to implement. In order to avoid interference, adjacent sawing mechanisms 14 can be staggered. For example, the odd-numbered sawing mechanisms 14 are located in the same plane, and the even-numbered sawing mechanisms 14 are located in another same plane, so as to avoid mutual interference between the mechanisms and improve the structural rationality.

[0089] In the above embodiments, if it is necessary to change from 12 equal parts to 13 equal parts, the adjustment is carried out in the same way with opposite steps.

[0090] In the above embodiments, since the No. 1, No. 3, No. 5, No. 1', No. 3', and No. 5' sawing mechanisms 14 are connected with the first driving member 15 and can all be withdrawn, therefore, this fragmenting mechanism can be flexibly switched between the fragmenting modes of 8 - 13 equal parts.

[0091] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, are similarly included in the patent protection scope of the present invention.
