Technical Field
[0001] The invention relates to the technical field of bamboo primary processing, and more specifically to an automatic bamboo sawing device for bamboo primary processing. Background Art
[0002] In recent years, the implementation of forest resource protection projects has led to a year-on-year decrease in timber production. At the same time, the rapid growth of the domestic economy has led to a booming furniture and catering industry, which has increased the demand for timber resources, resulting in an increasingly acute contradiction between timber supply and demand. Bamboo has become an ideal substitute for timber due to its advantages such as fast growth rate, short growth cycle, high strength-to-weight ratio, and easy processing, effectively alleviating the relationship between timber supply and demand. In the primary processing of bamboo, there are multiple links, including fixed-length sawing, sorting, bamboo splitting, slicing, rough planing, drying, and fine planing. Although the equipment for bamboo splitting, slicing, rough planing, and fine planing is relatively mature, the sawing link is still highly dependent on manual operation. Manual sawing is not only labor-intensive and has a low safety factor, but the utilization rate of bamboo is also limited by the operator's experience. In recent years, with the development of automation and intelligent technology, With rapid development, the bamboo processing industry is facing a major opportunity to transform from traditional processing to large-scale, automated and intelligent processing. Bamboo has bamboo nodes, which usually appear as ring-shaped protrusions. The part between two bamboo nodes is called "internodes", which are usually cylindrical. Their length and thickness vary depending on the bamboo species. During the sawing process, the normal sawing position is to saw the internode area, so the avoidance of bamboo nodes needs to be solved during the sawing process. The infrared detector currently used is to detect bamboo nodes to identify and avoid them during the sawing process.
[0003] However, the currently used infrared detectors still have limitations in bamboo joint detection. When encountering rainy weather, the bamboo will become smooth due to the erosion of rainwater. Since the infrared detector is very sensitive to the surface reflectivity of the detected object, the smooth surface of the bamboo will affect its detection results, making it difficult to effectively avoid bamboo joints when sawing bamboo. In view of this, we propose an automatic bamboo sawing device for primary processing of bamboo. Summary of the invention

The present invention can adjust the saw blade one and the saw blade two to a combined state or a separated state. In the combined state, the saw blade one and the saw blade two are in a single-blade sawing state. If the internode area of the bamboo is below the saw blade, the internode area of the bamboo is directly sawed using the single-blade sawing state. If the bamboo node area of the bamboo is below the saw blade, the saw blade one and the saw blade two are adjusted to a separated state to form a double-blade sawing state, and the areas on both sides of the bamboo node of the bamboo are sawed, so that the bamboo node can be effectively avoided during the sawing process.
[0016] 2. The present invention also designs a bamboo joint positioning mechanism, through the two hydraulic cylinders, the output ends of the two hydraulic cylinders extend to drive the movable bracket to move upward on the base, and drive the downward pressing assembly to move upward until the bamboo body enters the V-shaped structure of the contact plate and the top of the fixed side plate, and the outer wall of the bamboo is squeezed with the contact plate and the top of the fixed side plate. At this time, when the internode area of the bamboo is pressed on the top of the contact plate and the fixed side plate, since the internode of the bamboo is relatively flat and smooth, the contact plate cannot be pressed down. It only needs to make a contraction movement through the output ends of the two hydraulic cylinders to drive the movable bracket to move downward on the base, and further drive the saw unit to move downward with the movable bracket, so that the single-blade state formed by the combined saw blades 1 and 2 can saw the internode area of the bamboo; when the bamboo joint area of the bamboo is pressed on the top of the contact plate, due to the annular convex structure of the bamboo joint, the bamboo joint can squeeze the contact plate downward, and in the process of the contact plate moving downward, the pressure plate of the bottom pressure rod will press down the seesaw plate 1, so that the seesaw plate The first plate rotates around the fixed rod one, at this time, the seesaw plate one and the fixed rod one form a lever structure, which will drive the other end of the seesaw plate one to rise significantly. Similarly, the other end of the seesaw plate one rises significantly, which will drive the seesaw plate two with the lever structure to rotate around the fixed rod two, so that the other end of the seesaw plate two moves downward significantly, further driving the pull rod to move downward. The downward movement of the pull rod will pull the card block to rotate around the fixed rod three, so that the card block is separated from the movable plate and loses the card action on the movable plate. The movable plate is acted upon by the elastic force of the two springs one and moves in the direction away from the sawing bracket, driving the push-pull plate to pull the two sawing brackets to move synchronously in the opposite direction, so that the saw blade one and the saw blade two are in a separated state. In the separated state, the saw blade one and the saw blade two saw the areas on both sides of the bamboo joint of the bamboo material, and the extrusion force generated by the annular convex structure of the bamboo joint on the contact plate is used to judge the position area of the bamboo joint, and sawing is performed according to the position area of the bamboo joint, which effectively avoids sawing the bamboo joint, is not affected by water stains on the surface of the bamboo material, and improves the accuracy of avoiding the bamboo joint.

In the separated state, the saw blade 1 602 and the saw blade 2 604 saw the areas on both sides of the bamboo joint. During the sawing process, the movable plate 505 will drive the reset block 510 moves to the top of the reset plate 401. When sawing, the movable bracket 5 moves downward, driving the reset block 510 to rotate around the fixed plate 509 and move down to the bottom of the reset plate 401. When sawing is completed, the movable bracket 5 moves upward, driving the top inclined surface of the reset block 510 to form an extrusion with the bottom inclined surface of the reset plate 401, and gradually extruding and moving the reset block 510 in the direction of the clamping block 815, driving the movable plate 505 to move in the direction of the clamping block 815, until the clamping block 815 passes through the arc channel 508, forming a clamping structure for the movable plate 505, completing the reset of the movable plate 505, and at the same time driving the saw blade 1 602 and the saw blade 2 604 to reset from the separated state to the combined state, and performing the next sawing operation according to the above method;By utilizing the squeezing force generated by the annular protrusion structure of the bamboo joint on the contact plate 801, the position area of the bamboo joint is determined, and sawing is performed according to the position area of the bamboo joint, thereby effectively avoiding sawing the bamboo joint, being unaffected by water stains on the surface of the bamboo material, and improving the accuracy of avoiding the bamboo joint. ;

When in use, the bamboo materials are transferred from the multiple feeding rollers 102 of the feeding mechanism 1 to the multiple unloading rollers 301 of the unloading mechanism 3. After adjusting the position, the bamboo materials are clamped by the fixed clamping claw 103 and the fixed clamping claw 2 302, and the hydraulic cylinder 106 works to drive the rotating rod 105 to press downward, and further drive the pressing rod 104 to press down on the upper surface of the bamboo materials, further forming a fixing effect on the bamboo materials, and then, the output ends of the two hydraulic cylinders 2 404 extend out to drive the movable bracket 5 to move on the four convex strips 402 and two sliding rods 403 of the base 4. The bamboo material moves upward, driving the pressing assembly 8 to move upward until the main body of the bamboo material enters the V-shaped structure of the contact plate 801 and the top of the fixed side plate 701, and the outer wall of the bamboo material is squeezed with the contact plate 801 and the top of the fixed side plate 701. At this time, when the internode area of the bamboo material is pressed on the top of the contact plate 801 and the fixed side plate 701, the contact plate 801 cannot be pressed downward because the internode of the bamboo material is relatively flat and smooth. Then, the output ends of the two hydraulic cylinders 404 perform a contraction movement, driving the movable bracket 5 to move downward on the four convex strips 402 and the two sliding rods 403 of the base 4, and further driving the saw unit 6 to move downward following the movable bracket 5, so that the merged state The single blade state formed by the saw blade 1 602 and the saw blade 2 604 is used to saw the internode area of the bamboo; when the bamboo node area of the bamboo is pressed on the top of the contact plate 801, due to the annular convex structure of the bamboo node, the bamboo node can squeeze the contact plate 801 downward. During the downward movement of the contact plate 801, the pressing plate 807 of the bottom pressing rod 805 will press down the seesaw 1 808, so that the seesaw 1 808 rotates around the fixed rod 1 810. At this time, the seesaw 1 808 and the fixed rod 1 810 form a lever structure, which will drive the other end of the seesaw 1 808 to rise significantly. Similarly, the other end of the seesaw 1 808 rises significantly, which will drive the seesaw 2 811 with a lever structure to rotate around The movable plate 505 is moved away from the sawing bracket 605 by the elastic force of the two springs 1 506, driving the push-pull plate 507 to pull the two sawing brackets 605 to move in the opposite direction synchronously, so that the saw blade 1 602 and the saw blade 2 604 are in a separated state. In the separated state, the saw blade 1 602 and the saw blade 2 604 saw the areas on both sides of the bamboo node of the bamboo material.
