Description

Technical Field

[0001] This invention relates to the field of bamboo fiber preparation technology, specifically a bamboo fiber decomposition device. Background Technology

[0002] With the increasing prominence of environmental and climate issues, people are gradually pursuing green, low-carbon, and resource-based products. Bamboo fiber is being widely used due to its excellent properties such as abundant raw material sources, light weight, biodegradability, high specific modulus and strength, wear resistance, and heat insulation.

[0003] Bamboo fiber is produced by separating the bundled fibers in bamboo through mechanical processing after pre-treatment with chemical, biological, or physical softening agents. It can be in bundle, filament, or flocculent form. Bamboo fiber is a natural fiber that retains the original functional properties of bamboo fibers. Especially long bundled bamboo fibers have wide processing applicability and can be used in applications such as lightweight automotive interior materials and breathable textiles. Mechanical separation of fiber bundles is a crucial step in the preparation of bundled bamboo fiber. Because the width and thickness of the raw bamboo strips used in the preparation of bundled bamboo fiber are uneven, under fixed force and a fixed compression space, individual bamboo strips may be excessively compressed and jammed on the rollers, or insufficient force may result in incomplete separation. Simultaneously, due to the relatively small diameter of individual bamboo fiber bundles, improper roller tooth design can also lead to insufficient force on some fiber bundles, making separation difficult and resulting in hard strips and significant fiber bundle unevenness.

[0004] To address this, a bamboo fiber disintegration device is proposed. Summary of the Invention

A gear is rotatably connected to the outer wall of the dredging machine body, directly below the gear, and the gear meshes with the gear. A through-gear is fixedly connected to the gear. The drive shaft, located inside the main body of the sluice machine, is rotatably connected to a universal joint. A telescopic rod is fixedly connected to the end of the universal joint away from the inner wall of the sluice machine. A second universal joint is fixedly connected to the end of the telescopic rod away from the first universal joint. A first roller is rotatably connected to the end of the second universal joint away from the telescopic rod. The first roller is rotatably connected inside the sliding block. A second roller is fixedly connected to the end of the shaft on the gear two, located inside the main body of the sluice machine, and the second roller is rotatably connected inside the baffle.

[0012] Preferably, the variable pitch assembly further includes a second sliding groove, which is circumferentially and equidistantly formed on the outer wall of the second roller.

A third spring is fixedly connected between the second and the first tooth, and the third spring is sleeved on the outer wall of the connecting rod.

[0015] Preferably, the drive shaft is mounted on an external drive device, which is electrically connected to an external power supply and is used to drive the operation of the entire bamboo fiber disintegration device.

[0016] Preferably, a gap is provided between the roller shaft one and the tooth three for separating and loosening the fiber bundles of the bamboo strips.

[0017] Preferably, the end of the rotating rod near the outer wall of the main body of the slurry machine is provided with a threaded strip, and the nut has a threaded groove inside that matches the thread on the rotating rod. The rotating rod is threadedly connected to the threaded groove inside the nut through the threaded strip, and is used to push the protruding tooth by rotating the rotating rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When it is necessary to shorten the spacing of the three protruding teeth, the operator holds the handle and rotates the rotating rod to make the three protruding teeth gradually converge. When it is necessary to increase the spacing of the three protruding teeth, the rotating rod is rotated in the opposite direction to make the first protruding tooth slide in the opposite direction to make the three protruding teeth gradually disperse. Thus, the fiber dispersing density can be adjusted by adjusting the spacing of the three protruding teeth. At the same time, the spacing of the three protruding teeth can also be adjusted according to the width of the bamboo strips being conveyed, so that the device can still perform precise fiber dispersing when conveying multiple sets of bamboo strips at the same time, avoiding insufficient fiber dispersing that cannot meet the subsequent processing requirements.

[0020] 2. When the bamboo strips being decomposed are relatively thick, the bamboo strips push the first roller shaft upwards. When the thickness of the bamboo strips returns to normal, the first roller shaft moves downwards to a horizontal state. This makes the distance between the first roller shaft and the second roller shaft adjustable, allowing the bamboo fiber decomposition device to adapt to bamboo strips of different thicknesses. This increases the adaptability of the device and makes its application range wider. At the same time, it avoids the need to decompose the excessively thick bamboo strips separately when the bamboo strips are too thick, thus improving the processing efficiency of bamboo fiber decomposition.

[0021] 3. After cleaning with the extension plate, rotate the extension plate downwards to a vertical position. This allows the extension plate to be pulled to a horizontal position before the device is started, extending the length of the feeding platform. This avoids the bamboo strips being affected by a short feeding platform, and also prevents the bamboo strips from sagging due to lack of support, which would affect the fiber unwinding operation. After the device has finished processing and cleaning the extension plate, rotate the extension plate to a vertical position and store it inside the feeding platform, reducing the space occupied by the device.

[0022] 4. By adding steam nozzles to the feed inlet, humidification and heating can be achieved for some thick bamboo strips or bamboo strips that have not been fully softened, thereby improving the degree of softening and reducing the problem of differences in the degree of subsequent separation.

A push rod 78 is fixedly connected to the top of the second tooth 76 and the first tooth 74. A third tooth 79 is equidistantly fixed to the outer wall of the circular ring 73. A gap is provided between the roller 611 and the tooth 79 inside the sliding groove 2, which is slidably connected to the inside of the sliding groove 2. This gap is used to loosen the fiber bundles of the bamboo strips. A rotating rod 710 is rotatably connected to the side of the tooth 74 near the rotating groove 71.

The rotating rod 710 is threadedly connected to the threaded groove inside the nut 712 through the threaded strip. This is used to push the tooth 74 by rotating the rotating rod 710. A handle 713 is fixedly connected to the end of the rotating rod 710 outside the loosening machine body 1.

[0046] The following is the overall working principle of the above embodiments:

[0047] The initial state is as follows: extension plate 54 is in a vertical state, spring 1 57 is not stretched, spring 2 63 is not compressed, telescopic rod 69 is in a retracted state, and spring 3 77 is not compressed.

[0048] The following is the working status:

[0049] Adjust the spacing of the three 79 protrusions according to the width of the bamboo strip:

[0050] First, the external power supply to the equipment is not turned on, and the equipment is not started. If it is necessary to shorten the gap of the third tooth 79, the operator holds the handle 713 to rotate the rotating rod 710. Through the thread groove inside the nut 712 that matches the thread on the rotating rod 710, the rotating rod 710 moves into the interior of the main body 1 of the disintegrating machine. The movement of the rotating rod 710 pushes the first tooth 74 to slide along the outer wall of the connecting rod 75 inside the sliding groove 72 towards the second tooth 76 and compresses the third spring 77. The sliding of the first tooth 74 drives the third tooth 79 to slide away from the rotating groove 71 on the roller 612 through the ring 73. The first tooth 74 pushes the second tooth 76 away from the rotating groove 71 on the roller 612 through the push rod 78 at the top. The sliding of one side of the tooth 76 causes the sliding of the second tooth 76 to drive the third tooth 79 on the ring 73 where the second tooth 76 is located to slide towards the side of the roller 612 away from the rotating groove 71. In this way, the third tooth 79 gradually gathers together. If it is necessary to increase the spacing of the third tooth 79, the rotating rod 710 is rotated in the opposite direction to drive the first tooth 74 to slide in the opposite direction to make the third tooth 79 disperse. This makes the spacing of the third tooth 79 adjustable. The density of fiber bundle disintegration can be adjusted by adjusting the spacing of the third tooth 79. At the same time, the spacing of the third tooth 79 can also be adjusted according to the width of the bamboo strips being conveyed. This allows the device to perform precise fiber bundle disintegration when conveying multiple sets of bamboo strips at the same time, avoiding insufficient fiber bundle disintegration that cannot meet the needs of subsequent processing.

[0051] Extend the feeding platform 2 and decompose the bamboo fiber:

[0052] The operator pulls the extension plate 54 to rotate, which in turn rotates the rotating seat 53. The rotation of the rotating seat 53 then rotates the first rotating shaft 52 and the second rotating shaft 55. Simultaneously, the rotation of the rotating seat 53 stretches the first spring 57. When the extension plate 54 rotates to a horizontal position and comes into contact with the feeding platform 2, it extends the feeding platform 2, thus supporting the bamboo strips and preventing them from sagging due to lack of support, which could affect subsequent processing. At this point, the operator turns on the external power supply to the equipment. The drive unit is electrically connected to an external power source, which energizes the drive unit. Once energized, the drive unit drives gear 65 to rotate via drive shaft 66. The rotation of gear 65 drives gear 67, which meshes with it, to rotate synchronously. The rotation of gear 65 drives universal joint 68 to rotate synchronously. The rotation of universal joint 68, through telescopic rod 69 and universal joint 610, drives roller 611 to rotate synchronously. The rotation of gear 67 drives roller 612 to rotate synchronously. When the bamboo strips being split are thick, the bamboo strips push... The extrusion roller 611 moves upward, causing the sliding block 64 to slide upward inside the sliding groove 62 and compress the spring 63. The upward movement of the roller 611 causes the universal joint 610 to tilt upward and extend the telescopic rod 69. The tilting of the universal joint 610, through the telescopic rod 69, causes the universal joint 68 to tilt upward. When the bamboo strip thickness returns to normal, the roller 611 moves downward to a horizontal position, causing the sliding block 64 to slide upward inside the sliding groove 62. As the device slides downwards, spring 63 extends elastically, and roller 611 moves downwards, driving universal joint 610, telescopic rod 69, and universal joint 68 back to a horizontal state. This allows the distance between roller 611 and roller 612 to be adjustable, enabling the bamboo fiber debonding device to adapt to bamboo strips of different thicknesses. This increases the adaptability of the device and broadens its application range. At the same time, it avoids the need for separate debonding processing of excessively thick bamboo strips, thus improving the processing efficiency of bamboo fiber debonding.

[0053] As the bamboo strips slide between multiple debonding components, the scraper 613 removes bamboo yellow and other impurities from the bamboo strips. The water pressed out of the bamboo strips and the impurities scraped by the scraper 613 fall into the collection frame 4. The bamboo strips after fiber debonding slide out from the discharge platform 3 and are collected by the operator for the next processing step. When the bamboo fiber debonding device is finished, the operator cleans the extension plate 54 and rotates the extension plate 54 downward to a vertical position. This allows the extension plate 54 to be pulled to an upper horizontal position before the device is started, extending the length of the feeding platform 2. This avoids the bamboo strips being affected by the short feeding port and also prevents the bamboo strips from drooping due to lack of support, which would affect the fiber debonding operation. After the device finishes processing and the extension plate 54 is cleaned, the extension plate 54 is rotated to a vertical position and stored inside the feeding platform 2, reducing the space occupied by the device. The operator turns off the external power supply to the equipment, and the entire device returns to its initial state. The operator then processes the water and impurities collected in the collection frame 4.
