Description

Technical Field

[0001] The invention relates to the technical field of bamboo segment processing, in particular to an adjustable bamboo segment fragmentation 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 application number CN210589777U discloses a circular array saw blade assembly for circular bamboo. The assembly comprises multiple saw blade mechanisms and a power mechanism corresponding to each of the saw blade mechanisms and configured to drive the saw blade mechanisms. The saw blades within the saw blade mechanisms are arranged in a circular array around the central axis of the circular bamboo being sawed. The advantages of this utility model are that the saw blades are arranged in a circular array around the central axis of the circular bamboo being sawed, enabling the circular cylinder to be cut into circularly arranged bamboo strips. The cutting method employed improves the flatness of the bamboo strips' sides compared to traditional stamping methods. This prevents excessive planing of the sides during fine planing, thereby increasing bamboo material utilization.

[0004] However, in the above patent solution, the positions of the circular array distribution of each saw blade are fixed, so it can only be applied to a method of dividing the round bamboo into bamboo pieces in equal parts. For example, if the saw blades are distributed in 8 equal parts, it cannot be applied to 12 equal parts.

[0005] Since the blades on the cutter disc are fixed in the traditional punching and breaking method, the round bamboo can be broken into bamboo pieces of equal size in a manner suitable for various specifications by replacing or switching the cutter disc.

[0006] In summary, although the above patent solution adopts the circular array saw blade bamboo breaking method compared with the traditional punching fragmentation method, it has the advantages of good flatness and high bamboo material utilization, it is only applicable to one specification of round bamboo (bamboo segment) fragments.

[0007] Therefore, how to improve the bamboo sawing mechanism so that it can simultaneously meet the requirements of good slice flatness, high bamboo material utilization, and be applicable to a variety of fragmentation methods with different equal-division specifications has become a technical problem that needs to be solved urgently.

[0049] Please refer to Figures 1 to 6 , a specific embodiment of the present invention relates to an adjustable bamboo segment breaking mechanism, comprising a fixing frame 1, a fixed connecting seat 2, a movable connecting seat 3, a plurality of sawing mechanisms 4, a first driving member 5 and a second driving member 6;

[0050] The middle portion of the fixing frame 1 is provided with a through hole 11 for accommodating the axial passage of the bamboo segment;

[0051] The fixed connection seat 2 is fixedly connected to the fixing frame 1;

[0052] The movable connecting seat 3 is movably connected to the fixed frame 1, and the movable connecting seat 3 moves in a direction of rotation about the axis of the through hole 11. The plurality of movable connecting seats 3 and the fixed connecting seats 2 are distributed in a circular array with the center of the through hole 11 as the center of the circle;

[0053] The sawing mechanism 4 includes a mounting base 41, a saw blade 43 and a drive motor 42. The saw blade 43 is rotatably connected to the mounting base 41. The drive motor 42 is fixedly connected to the mounting base 41. The drive motor 42 is in transmission connection with the saw blade 43 for driving the saw blade 43 to rotate.

[0054] A mounting base 41 of one of the sawing mechanisms 4 is fixedly connected to the fixed connection base 2;

[0055] The mounting base 41 of one or more sawing mechanisms 4 is fixedly connected to the movable connecting base 3;

[0056] The mounting seats 41 of at least one sawing mechanism 4 are movably connected to the movably connecting seat 3 , and the movable direction of the mounting seats 41 is the radial direction of the through hole 11 ;

[0057] The first driving member 5 is connected between the movable connection seat 3 and the mounting seat 41, and the first driving member 5 is used to drive the mounting seat 41 to move along the radial direction of the through hole 11;

A sawing mechanism 4 is connected to each movable connection seat 3 and the fixed connection seat 2 respectively, and a driving motor 42 is used to drive the saw blade 43 to rotate at a high speed to divide the bamboo segment conveyed through the through hole 11 into equal parts and break it into bamboo pieces. Since the movable connection seat 3 can rotate a certain angle along the axis of the through hole 11, and the mounting seat 41 of the part of the sawing mechanism 4 is movably connected to the movable connection seat 3, when it is necessary to adjust the bamboo segment breaking When the number of equal divisions of the bamboo segments is adjusted, the sawing mechanism 4 that is movably connected to the movable connecting seat 3 can be controlled to move radially along the through hole 11, and then the other movable connecting seats 3 are adjusted to rotate to the corresponding predetermined angles to achieve the purpose of adjusting the number of equal divisions of the bamboo segments. Since the method of breaking the bamboo segments by high-speed rotation of the saw blade 43 has the advantages of good slicing flatness and high bamboo material utilization compared to the traditional stamping cutter disc structure, the adjustable bamboo segment breaking mechanism involved in the present invention can simultaneously meet the requirements of good slicing flatness, high bamboo material utilization, and is applicable to a variety of fragmentation methods with different equal division specifications.

[0060] As an optional embodiment, the movable connecting seat 3 movably connected to the mounting seat 41 and the movable connecting seat 3 fixedly connected to the mounting seat 41 are spaced apart. Since the number of bamboo fragments is generally adjusted between 8 and 13, it is not necessary to adjust all the sawing mechanisms 4 radially along the center of the circular array. The above-mentioned arrangement of the movable connecting seat 3 and the movable connecting seat 3 fixedly connected to the mounting seat 41 at intervals can reduce the rotational stroke of each sawing mechanism 4 when adjusting the number of fragments.

The first driving member 5 is connected to the sawing mechanism 4 through the connecting member 7 through the hollow portion 33. Figure 2 Since the first driving member 5 (cylinder) and the sawing mechanism 4 are respectively distributed on both sides of the movable connecting plate 32, the spatial distribution is more reasonable and interference between components is avoided.

[0065] As an optional embodiment, the number of the movable connection seats 3 is 12, and the number of the movable connection seats 3 movably connected to the mounting seat 41 is 6.

[0066] Example 1

[0067] Please refer to Figure 7, which shows a schematic diagram of the principle of an adjustable bamboo fragmentation mechanism. The figure shows 13 groups of sawing mechanisms 4, where each circled number represents a sawing mechanism 4. Among them, sawing mechanism 4 No. 7 is fixedly connected to the fixed connection base 2 and its position cannot be adjusted. The other sawing mechanisms 4 are connected to the movable connection base 3 and the first driving member 5, which can rotate a certain angle along the center of the circular array. Among them, sawing mechanisms 4 No. 1, No. 3, No. 5, No. 1', No. 3', and No. 5' are connected to the first driving member 5 and can move radially along the circumferential array.

[0068] Figure 7 In the diagram, the inner circled numbers represent the state in which the saw blades 43 of the 13 sawing mechanisms 4 are arranged in a circular array for sawing a bamboo segment into 13 equal parts. The outer circled numbers represent the state in which one of the sawing mechanisms 4, numbered 1', is driven by the first driving member 5 to move radially outward in the circular array. After leaving the circular array, the other 12 sawing mechanisms 4 are rotated by a certain angle to reach a state in which the saw blades 43 of the 13 sawing mechanisms 4 are arranged in a circular array with 12 equal parts, and are used to saw a bamboo segment into 12 equal parts. Figure 7 In the figure, the position of sawing mechanism 4 No. 7 remains unchanged. When sawing mechanism 4 No. 1' is pulled out, each sawing mechanism 4 on both sides of sawing mechanism 4 No. 7 rotates a certain angle respectively under the drive of the second driving member 6. No. 6' rotates 2.31 degrees counterclockwise, No. 6 rotates 2.31 degrees counterclockwise, No. 5' rotates 4.62 degrees counterclockwise, No. 5 rotates 4.62 degrees counterclockwise, No. 4' rotates 6.92 degrees counterclockwise, No. 4 rotates 6.92 degrees counterclockwise, No. 3' rotates 9.23 degrees counterclockwise, No. 3 rotates 9.23 degrees counterclockwise, No. 2' rotates 11.54 degrees counterclockwise, No. 2 rotates 11.54 degrees counterclockwise, No. 1' rotates 1.15 degrees clockwise, and No. 1 rotates 13.85 degrees clockwise.

[0069] In the above embodiment, when the division is changed from 13 equal parts to 12 equal parts, the rotation angle of each sawing mechanism 4 is less than 15 degrees, and the stroke requirement for the second driving member 6 is small and easy to implement. In order to avoid interference, adjacent sawing mechanisms 4 can be staggered. For example, odd-numbered sawing mechanisms 4 are located in the same plane, and even-numbered sawing mechanisms 4 are located in another same plane, so as to avoid mutual interference between the mechanisms and improve structural rationality.

[0070] In the above embodiment, if it is necessary to change from 12 equal divisions to 13 equal divisions, the adjustment is performed in the opposite steps.

[0071] In the above embodiments, since the No. 1, No. 3, No. 5, No. 1', No. 3', and No. 5' sawing mechanisms 4 are connected to the first driving member 5 and can be withdrawn, the fragmentation mechanism can flexibly switch between 8-13 equally divided fragmentation modes.

[0072] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
