Description

Technical Field

[0001] This invention relates to the field of bamboo product processing technology, specifically to a device for removing yellowing from bamboo tubes. Background Technology

[0002] Removing the yellow part of bamboo is a common step in bamboo processing, especially when making bamboo containers, tea scoops, pen holders, and other items that require a smooth and beautiful inner wall or improved structural strength. The yellow part of bamboo is relatively loose and fragile, light yellow in color, sometimes with brown spots, and easily absorbs water and is prone to mold. Removing it can significantly improve the durability and appearance of bamboo products.

[0003] Patent CN113276240B discloses a bamboo tube yellowing removal machine, which includes a yellowing removal device and a clamping device. The clamping device is equipped with a first driving device for driving the clamping device to rotate. A cutting device and a shaping device are equipped with mounting bases, both of which are mounted on the mounting bases. An adjusting device is located at the bottom of the mounting base. The cutting device includes a cutting blade and a second driving device for driving the cutting blade to rotate. The shaping device includes a roller for abutting against and rolling along the outer surface of the bamboo tube. A set gap is formed between the cutting blade and the roller. The adjusting device includes a slide rail and an elastic element. The mounting base can move along the length direction of the slide rail under the action of external force, and the elastic element is used to reset the mounting base. The yellowing removal device is equipped with a pushing device for moving the yellowing removal device, which can move along the length direction of the guide rail. One end of the elastic element abuts against a support base, and the other end of the elastic element abuts against a first slider.

[0004] However, this device is difficult to efficiently feed and process materials when faced with a large number of processing scenarios. Moreover, the surface of the bamboo tubes is slippery and easy to slip out of the hand, resulting in a high rate of work-related injuries during manual handling. Therefore, the overall operating efficiency of the device is low. Hence, a de-yellowing device for bamboo tubes is proposed to solve the above-mentioned problems. Summary of the Invention

[0025] 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.

[0026] Please see Figures 1-11One embodiment of the present invention is: a device for removing yellowing from bamboo tubes, comprising a base 1, a table panel 2 fixedly connected to the top of the base 1, a conveyor belt 3 provided on the inner wall of the table panel 2, a feeding mechanism 4 provided on the top of the conveyor belt 3, a fixing mechanism 5 provided at the rear of the feeding mechanism 4, a planing mechanism 6 installed at the rear of the fixing mechanism 5, a discharge port 7 opened on the table panel 2 at the bottom of the fixing mechanism 5, a guide groove opened on the inner wall of the discharge port 7, the feeding mechanism 4 comprising: a partition 401, an arc-shaped guide plate 402, a motor 403, a mounting bracket 404, a cam 405, a chain 406, a connecting shaft 407, a spray gun 408, a stop bar 409, a drainage trough 410, and a conveyor wheel 411, the partition 401 being fixedly connected to the top of the table panel 2, the front end of the arc-shaped guide plate 402 being hinged to the top of the table panel 2 by a torsion spring, and the other end of the arc-shaped guide plate 402 being slidably connected to the arc surface of the partition 401. The mounting bracket 404 is fixedly connected to the outer wall of the partition 401, the cam 405 is rotatably connected to the inner wall of the mounting bracket 404, the motor 403 is fixedly connected to the top of the platform 2 via a bracket, the coupling 407 is rotatably connected to the inner wall of the partition 401 via a torsion spring, the spray gun 408 is fixedly connected to the circumferential surface of the coupling 407, the stop bar 409 is fixedly connected to the circumferential surface of the coupling 407, the conveyor wheel 411 is fixedly connected to the top of the partition 401 and driven by the motor, the inner wall of the partition 401 is provided with a strip groove, the movement trajectory of the spray gun 408 and the coupling 407 both pass through the strip groove provided in the inner wall of the partition 401, the angle between the installation positions of the spray gun 408 and the coupling 407 is 90 degrees, the cam 405 is in contact with the arc-shaped guide plate 402, the cam 405 is connected to the output end of the motor 403 via a chain 406, and the platform 2 between the two partitions 401 is provided with a drainage groove 410.

[0027] Working principle: When the device starts, the conveyor belt 3 moves and transports the bamboo tube to the space between the arc-shaped guide plates 402. At this time, the motor 403 starts and drives the cam 405 to rotate through the chain 406. When the cam 405 rotates, the protrusion of the cam 405 contacts and pushes the arc-shaped guide plate 402 to rotate around the connection point. The rotation of the guide plate 402 compresses the torsion spring inside the connection point. As the cam 405 rotates, the arc-shaped guide plate 402 will swing back and forth, intermittently pushing the bamboo tube. In conjunction with the conveyor belt 3, the bamboo tube can enter between the two partitions 401 at a suitable processing angle. At the same time, the swinging guide plate 402 can also effectively reduce the probability of the bamboo tube getting stuck and blocking the device, and improve the stability of the device. As the conveyor wheel 411 rotates and contacts the bamboo tube, it continues to move forward. During the forward movement of the bamboo tube, the spray gun 408 sprays softening liquid into the inner wall of the bamboo tube, softening the bamboo yellow inside and improving the subsequent scraping effect. In addition, it can also reduce the dust generated during subsequent scraping and improve the safety of the device. During the forward movement of the bamboo tube, it will contact the stop bar 409 and push the stop bar 409 to rotate as it moves. The rotation of the stop bar 409 drives the connecting shaft 407 to rotate and compresses the torsion spring inside the connecting shaft 407. The rotation of the connecting shaft 407 drives the spray gun 408 to rotate into the slot inside the partition plate 401 to prevent it from blocking the bamboo tube from moving forward. After the bamboo tube enters the planing area, the connecting shaft 407 resets and drives the spray gun 408 to reset for subsequent bamboo tube softening. After the bamboo tube has been sprayed, it will be pushed into the planing area by the conveyor wheel 411 for processing to remove the yellow.

[0028] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the fixing mechanism 5 includes: a mounting plate 501, an electric telescopic rod 502, a second motor 503, and a rubber wheel 504.

The slider 505 is slidably connected to the inner wall of the discharge port 7, and the driven wheel 506 rotates... A sliding connection is made to the inner wall of slider 505, a pin 507 is slidably connected to the inner wall of the table panel 2, a connecting block 508 is fixedly connected to the rear of pin 507, a guide rod 509 is fixedly connected to the inner wall of the guide groove on the inner wall of the discharge port 7, a return spring is provided on the circumferential surface of the guide rod 509, the inner wall of slider 505 is slidably connected to the circumferential surface of guide rod 509, an oval positioning hole is opened on the surface of slider 505, a baffle 8 is fixedly connected to the front of the mounting plate 501, slider 505 and guide rod 509 are symmetrically arranged on the inner wall of discharge port 7, pin 507 is located in the oval positioning hole inside slider 505 near the side of planing mechanism 6 in the initial position, planing mechanism 6 The planing mechanism 6 includes: a connecting frame 601, a movable plate 602, and a hydraulic telescopic rod 603. The connecting frame 601 is fixedly connected to the top of the table panel 2. A guide groove is provided on the inner wall of the connecting frame 601. The movable plate 602 is slidably connected to the guide groove on the inner wall of the connecting frame 601. The hydraulic telescopic rod 603 is fixedly connected to the inner wall of the connecting frame 601. The planing mechanism 6 also includes: a cylindrical planer blade 604, a mounting ring 605, an elastic telescopic rod 606, a second connecting block 607, a sliding sleeve 608, a protrusion 609, and a second slider 610. The mounting ring 605 is fixedly connected to the front of the movable plate 602. The second slider 610 is slidably connected to the inner wall of the mounting ring 605. 604 is rotatably connected to the inner wall of slider 610. Connecting block 607 is fixedly connected to the side of slider 610 away from cylindrical planer 604. Elastic telescopic rod 606 is fixedly connected between the two connecting blocks 607. Sliding sleeve 608 is slidably connected to the surface of moving plate 602. Sliding sleeve 608 has an angled protrusion on the side near cylindrical planer 604, and the angled protrusion contacts connecting block 607. Protrusion 609 is fixedly connected to the inner wall of connecting frame 601. The output end of hydraulic telescopic rod 603 is fixedly connected to moving plate 602. Protrusion 609 is located on the movement trajectory of sliding sleeve 608. Both ends of moving plate 602 are fixedly connected to connecting block 508.

[0029] Working principle: When the bamboo tube enters the planing area and contacts the two driven wheels 506, the electric telescopic rod 502 descends, causing the mounting plate 501 to move downwards. The downward movement of the mounting plate 501 causes the second motor 503 to move downwards, which in turn causes the rubber wheel 504 to move downwards until it contacts the bamboo tube. At this time, the hydraulic telescopic rod 603 starts and pushes the moving plate 602 forward. The forward movement of the moving plate 602 causes the sliding sleeve 608 to move. During the movement, the sliding sleeve 608 contacts and is squeezed by the protrusion 609, causing the sliding sleeve 608 to move in the direction of the protrusion 609. The movement of the sliding sleeve 608 pushes the second connecting block 607. Connecting block 2 607 drives slider 2 610 to move and compress elastic telescopic rod 606. Slider 2 610 moves and drives cylindrical planer 604 to bring the two cylindrical planer 604 together. As the two cylindrical planer 604 come together, it can adapt to bamboo tubes of different diameters, improving the applicable range of the lifting device. After the cylindrical planer 604 enters the bamboo tube, sliding sleeve 608 moves past protrusion 609. Under the force of the elastic telescopic rod 606 returning to its original position, the cylindrical planer 604 reopens and contacts the inner wall of the bamboo tube. Motor 2 503 starts and drives rubber wheel 504 to rotate. The rotation of rubber wheel 504 drives the bamboo tube to rotate through friction. As the bamboo tube rotates... The internal cylindrical planer 604 scrapes off the bamboo core. As the moving plate 602 moves, it also moves the connecting block 508. The movement of the connecting block 508 causes the pin 507 to insert into the oval positioning holes inside the two sliders 505, preventing the bamboo tube from being squeezed out of the device. Because the slider 505 can still move slightly after the pin 507 is inserted into the oval positioning holes inside the slider 505, it effectively protects the irregularly shaped bamboo tube from being cracked by the rubber wheel 504, improving the device's yield rate. After the bamboo tube is cut, the hydraulic telescopic rod 603 retracts, causing the moving plate 602 to move back. The moving plate 602 then moves the connecting block 508. When block 508 moves back, connecting block 508 moves back, causing pin 507 to move back until pin 507 completely leaves the oval positioning hole inside the two sliders 505. At this time, slider 505 loses its constraint and moves along the direction of guide rod 509 under the weight of the bamboo tube, compressing the return spring on the circumference of guide rod 509. After the bamboo tube falls, slider 505 moves back under the force of the return spring. Then, hydraulic telescopic rod 603 resets, causing pin 507 to re-insert into one of the sliders 505. This design greatly improves the discharge rate, eliminates the need for manual intervention, reduces labor costs, and improves the overall operating efficiency of the device.
