Description

Technical Field

[0001] This invention relates to the field of bamboo processing technology, specifically to a method and apparatus for removing green and yellow protruding nodes from bamboo. Background Technology

[0002] Patent CN119429610A discloses a vertical bamboo cleaning machine, characterized by comprising a frame and a flipping feeding mechanism, a bamboo cleaning mechanism, and a feeding conveying mechanism sequentially installed on the frame. The flipping feeding mechanism is used to flip the bamboo tube upwards to be perpendicular to the frame. The bamboo cleaning mechanism is used to remove the bamboo partitions inside the vertical bamboo tube. The feeding conveying mechanism transports the bamboo tube with the bamboo partitions removed to the subsequent production line.

[0003] Patent CN223356740U discloses a bamboo tube flipping and feeding mechanism, including a frame, a bamboo tube clamp, a flipping component, and a limiting component. The bamboo tube clamp is installed on the frame. The limiting component includes a limiting member and a pushing member. The limiting member is located at the rear of the frame and is used to limit the bamboo tubes in the bamboo tube clamp from moving further forward. The pushing member is located at the head of the frame and is used to push the bamboo tubes in the bamboo tube clamp towards the limiting member. The flipping component is installed on the frame.

[0004] The general processing procedure for bamboo flat panels is as follows: A section of bamboo is cut from the middle, then into smaller segments. The raised areas at the nodes on the outer green surface are removed manually, and the raised areas on the inner yellow surface are removed at intervals. After this process, the next step is determined based on whether the green or yellow bamboo is still needed. After removing the raised areas, the inner and outer surfaces of the bamboo tube become smooth. An axial opening is then made, and the tube is placed in a flat paneling machine for moist heat treatment. Finally, the flattened bamboo tube becomes a bamboo flat panel.

[0005] Previously, the process of removing protrusions from the inner and outer surfaces was done manually, which was time-consuming and labor-intensive. During the removal process, it was easy to cause problems such as removing too much or too little material, which would create weak points of stress during the wet heat flattening process, easily causing cracking and other problems, resulting in low yield and low efficiency.

[0006] Therefore, a method and apparatus for removing green and yellow protruding nodes from bamboo are proposed to solve the problems mentioned above. Summary of the Invention

[0008] In one possible implementation, the bamboo yellowing removal device includes a pneumatic rod, which is bolted to the side wall of the frame, and a guide rail is bolted to the side wall of the frame, with a slider slidably connected to the guide rail.

[0009] In one possible implementation, a motor is bolted to the slider, the output shaft of the motor is fixedly connected to a universal joint, the other end of the universal joint is fixedly connected to a ball end mill, the ball end mill is slidably connected to a movable plate at the upper end of the telescopic device, and the telescopic device is fixedly connected to the frame. The upper end of the telescopic device has second limit pulleys rotatably connected to the left and right side walls of the movable plate.

[0010] In one possible implementation, the bamboo tube clamping device includes a gear reversing mechanism, and the frame sidewall is provided with the gear reversing mechanism and a motor.

[0011] In one possible implementation, the gear reversing mechanism is connected to the motor, and the gear reversing mechanism is connected to steel rope one and steel rope two. Steel rope one is connected to the upper end of the upper pressure plate, and steel rope two is connected to the bottom of the lower pressure plate. The upper pressure plate and the lower pressure plate are slidably connected to the side wall of the frame through springs.

[0012] In one possible implementation, a contact wheel is rotatably connected to the upper and lower pressure plates, and a drive motor is fixedly connected to the back of the other end of the upper and lower pressure plates. The drive motor drives the contact wheel to rotate and connect with the upper and lower pressure plates.

[0013] In one possible implementation, the corners of steel rope one and steel rope two are supported by fixed pulleys, which are set on the side wall of the frame.

[0014] In one possible implementation, a display is fixedly connected to the top of the frame, and placement plates are fixedly connected to the left and right ends of the top of the frame.

[0015] In one possible implementation, a guide plate is provided at each of the front and rear ends of the frame of the belt conveyor, and the guide plate is used to guide the crushed material above to the belt conveyor.

[0016] A method for removing green and yellow raised nodes from bamboo includes the following steps: Step 1: Place the separated bamboo tubes into the grooves on the placement plate, start the motor, the motor drives the gear reversing mechanism, the gear reversing mechanism drives steel rope one and steel rope two to move outwards at the same time, steel rope one and steel rope two release the tension on the upper and lower pressing plates, the upper and lower pressing plates are reset by the action of the spring, the two sets of upper and lower pressing plates move closer to each other, the two sets of upper and lower pressing plates drive the contact wheel to contact the four sides of the bamboo tube, and clamp and fix the bamboo tube; Step 2: After the bamboo tube is clamped, the motor and the milling cutter motor start.

Step 3: The telescopic device moves downwards until the second limit pulley contacts the inner wall of the bamboo tube. At the same time, the telescopic device can also extend and retract in real time to ensure a constant depth of cut, so that the ball end mill head can just mill the inner section of the bamboo tube. The pneumatic rod and the secondary pneumatic rod are then activated simultaneously to push the slider towards the bamboo tube, and the two end mills begin milling. After milling begins, the contact wheel drives the bamboo tube to rotate. After one rotation, the outer protrusion of the green bamboo and the inner section and protrusion of the yellow bamboo are milled smooth. The bamboo chips fall into the conveyor belt on the belt conveyor below and are conveyed out of the equipment. After milling is completed, the device is retracted in the reverse order of the above steps to complete one processing cycle.

[0017] Compared with the prior art, the present invention provides a method and apparatus for removing green and yellow raised nodes from bamboo, which has the following beneficial effects: This invention smooths the surface of the bamboo tube by milling the protrusions on the green part and the internodes and protrusions of the bamboo. This facilitates further processing of the bamboo tube and replaces the traditional manual removal of green and yellow protrusions. It achieves uniform removal of green and yellow protrusions from the bamboo tube and avoids the uneven material removal problem caused by manual processing. At the same time, it greatly increases the processing speed and improves the efficiency of the initial processing of bamboo tubes. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-4 The method and apparatus for removing green and yellow protruding nodes of bamboo in this embodiment include a frame 101. A primary pneumatic rod 1 is bolted to the frame 101. The movable end of the primary pneumatic rod 1 is fixedly connected to a connecting plate 102 and drives the connecting plate 102 to slide on the frame 101. Specifically, a secondary pneumatic rod 2 is bolted to the connecting plate 102. The movable end of the secondary pneumatic rod 2 is fixedly connected to the base of the milling cutter motor 3 and drives the base of the milling cutter motor 3 to slide and connect with the top of the connecting plate 102. Specifically, the output shaft of the milling cutter motor 3 is fixedly connected to the milling cutter head 4; Specifically, the first limiting pulley 5 is rotatably connected to the side wall of the base of the milling cutter motor 3; Specifically, a pneumatic rod 6 is bolted to the side wall of frame 101, a guide rail 61 is bolted to the side wall of frame 101, and a slider 62 is slidably connected to the guide rail 61.

[0022] Specifically, during operation, after the bamboo tube is clamped, motor 7 and milling cutter motor 3 start. The primary pneumatic rod 1 drives the connecting plate 102 to move. The connecting plate 102 drives the secondary pneumatic rod 2, milling cutter motor 3, milling cutter head 4, and first limiting pulley 5 to advance towards the bamboo tube, stopping when it approaches the bamboo tube (about 5mm away). Subsequently, the secondary pneumatic rod 2 drives the milling cutter motor 3, milling cutter head 4, and first limiting pulley 5 to advance until they contact the bamboo tube and stop. The first limiting pulley 5 presses against the two sides of the protrusion on the outer edge of the bamboo tube, controlling the milling cutter head 4 to avoid over-milling. At the same time, it reduces the air pressure of the secondary pneumatic rod 2. When encountering changes in the depth of cut caused by the rotation of a regular circular bamboo tube, the secondary pneumatic rod 2 can elastically adjust in real time according to the protrusion or concavity during rotation. This works in conjunction with the first limiting pulley 5. The telescopic device 9 moves downward until the second limit pulley 11 contacts the inner wall of the bamboo tube. At the same time, the telescopic device 9 can also extend and retract in real time to ensure a constant depth of cut, so that the ball end mill head 10 can just mill the inner section of the bamboo tube. The pneumatic rod 6 and the secondary pneumatic rod 2 are then activated simultaneously to push the slider 62 toward the bamboo tube, and the two end mills begin milling. After milling begins, the contact wheel drives the bamboo tube to rotate. After one rotation, the outer protrusions of the green bamboo and the inner nodes and protrusions of the yellow bamboo are milled smooth. The bamboo chips fall into the conveyor belt on the belt conveyor 105 below and are conveyed out of the equipment. After milling is completed, the device retracts its action in the reverse order of the above steps to complete one processing cycle.

[0023] Please see Figures 1-7 A motor 7 is bolted to the slider 62. The output shaft of the motor 7 is fixedly connected to the universal joint 8. The other end of the universal joint 8 is fixedly connected to the ball end mill 10. The ball end mill 10 is slidably connected to the moving plate at the upper end of the telescopic device 9. The telescopic device 9 is fixedly connected to the frame 101. Specifically, second limiting pulleys 11 are rotatably connected to the left and right side walls of the movable plate at the upper end of the telescopic device 9; Specifically, a gear reversing mechanism 12 and a motor 13 are provided on the side wall of the frame 101; Specifically, the gear reversing mechanism 12 is connected to the motor 13, and the gear reversing mechanism 12 is connected to steel rope 14 and steel rope 2 15. Steel rope 14 is connected to the upper end of the upper pressure plate 16, and steel rope 2 15 is connected to the bottom of the lower pressure plate 17. The upper pressure plate 16 and the lower pressure plate 17 are slidably connected to the side wall of the frame 101 through springs. Specifically, contact wheels are rotatably connected to the upper pressing plate 16 and the lower pressing plate 17, and a drive motor is fixedly connected to the back of the other end of the upper pressing plate 16 and the lower pressing plate 17. The drive motor drives the contact wheels to rotatably connect with the upper pressing plate 16 and the lower pressing plate 17. Specifically, the corners of steel rope 14 and steel rope 2 15 are supported by fixed pulleys, which are installed on the side wall of frame 101. Specifically, a display 103 is fixedly connected to the top of the frame 101, and a placement plate 104 is fixedly connected to the left and right ends of the top of the frame 101. A belt conveyor 105 is provided in the lower part of the frame 101, and the belt conveyor 105 is located below the processing area of ​​the milling cutter motor 3 and the ball milling cutter head 10. Specifically, during operation, the separated bamboo tubes are placed into the grooves on the placement plate 104, and the motor 13 is started. The motor 13 drives the gear reversing mechanism 12, which in turn drives steel rope 14 and steel rope 2 15 to move outwards simultaneously. Steel rope 14 and steel rope 2 15 release the tension on the upper pressing plate 16 and the lower pressing plate 17. The upper pressing plate 16 and the lower pressing plate 17 are then reset by the action of the spring. The two sets of upper pressing plates 16 and lower pressing plates 17 move closer to each other, and the two sets of upper pressing plates 16 and lower pressing plates 17 drive the contact wheels to contact the four sides of the bamboo tube, thus clamping and fixing the bamboo tube.
