Description

Technical Field

[0001] This invention relates to the field of fiber opening technology, specifically to a bamboo pulp fiber opening device and method. Background Technology

[0002] Bamboo pulp fiber, as an important renewable and environmentally friendly material, is widely used in textiles, nonwovens, and other fields. Its production process requires opening compacted bamboo pulp fiber blocks into loose, single-fiber states. Traditional opening equipment mainly draws on the opening principles of cotton spinning or chemical fiber processing. Common opening equipment for bamboo pulp fibers often suffers from unstable fiber conveying. Due to the dense structure and high toughness of bamboo pulp fiber blocks, conventional conveying devices are prone to insufficient clamping force or uneven pressure, causing fiber blocks to accumulate, slip, or even clog the equipment at the inlet, resulting in incomplete opening and affecting continuous production. Incomplete opening also leads to low efficiency in peeling the bamboo pulp fiber layer, leaving behind unopened fiber clumps. Furthermore, the intense interaction between rigid opening elements and the fibers can easily cut long fibers, reducing the quality of the finished product. During the opening process, some fine fibers escape with the airflow, causing environmental pollution and raw material waste. Summary of the Invention

[0015] (Three) beneficial effects Compared with the prior art, the bamboo pulp fiber opening device and the method thereof have the following beneficial effects: 1. The bamboo pulp fiber opening device and method involves conveying bamboo pulp fiber blocks to the opening unit via a stable conveying unit. First, the drive mechanism is adjusted to drive the stable conveying unit and the opening unit to operate. The upper and lower conveying mechanisms in the stable conveying unit sandwich the bamboo pulp fiber blocks in the middle and convey them into the opening cylinder. When the bamboo pulp fiber blocks are conveyed to the opening cylinder, the lower pressure plate on one side of the opening cylinder presses down on the bamboo pulp fiber blocks, thereby facilitating the entry of the bamboo pulp fiber blocks into the opening cylinder. Then, the rotating piercing roller inside the opening cylinder tears off the bamboo pulp fiber blocks layer by layer, so that the bamboo pulp fiber blocks enter the opening cylinder in a thin filament state, thereby completing the opening process of the bamboo pulp fiber blocks.

[0016] 2. The bamboo pulp fiber opening device and method, wherein the bamboo pulp fiber blocks are sandwiched in the middle and conveyed into the opening cylinder through the upper conveying mechanism and the lower conveying mechanism in the stable conveying unit; wherein, the conveying toothed belt in the upper conveying mechanism, driven by the stable conveying roller and under the action of the lower pressing convex roller, presses down the bamboo pulp fiber blocks and performs stable conveying; the lower conveying belt in the lower conveying mechanism, driven by the supporting conveying roller, cooperates with the conveying toothed belt to perform stable conveying of the bamboo pulp fiber blocks; when conveying bamboo pulp fiber blocks of different thicknesses, the telescopic adjustment rod adjusts the height between the upper conveying frame and the lower conveying frame, thereby matching bamboo pulp fiber blocks of different thicknesses.

[0017] 3. The bamboo pulp fiber opening device and method utilize a rotating quenching roller inside the opening cylinder. Short quenching plates on the surface of the quenching roller, in conjunction with tearing teeth at the bottom of the opening cylinder's inner cavity, tear the bamboo pulp fibers entering the opening cylinder, removing and carrying away a portion of the bamboo pulp fibers at the tearing teeth. When the long quenching plates on the quenching roller pass over the tearing teeth, they tear off and carry away the remaining bamboo pulp fibers, thus enabling the bamboo pulp fibers to be more dispersed and preventing the bamboo pulp fibers after opening from forming large fiber clumps.

[0018] 4. The bamboo pulp fiber opening device and method involves tearing the bamboo pulp fiber blocks into the opening cylinder layer by layer, so that the bamboo pulp fiber blocks enter the opening cylinder in a thin filament state, thereby completing the opening process of the bamboo pulp fiber blocks. During the opening process, the dust removal channel in the opening unit creates negative pressure inside the opening cylinder (the dust removal channel is connected to an external negative pressure device) while the bamboo pulp fibers are being opened, thereby discharging dust and other impurities generated inside the opening cylinder. At the same time, the flexible comb plate intercepts the bamboo pulp fibers in the air, preventing the bamboo pulp fibers from clogging the filter holes. When the barbed roller inside the opening cylinder passes through the flexible comb plate, the barbed roller carries out the bamboo pulp fibers in the flexible comb plate, so that the bamboo pulp fibers in the flexible comb plate are mixed with other bamboo pulp fibers, avoiding waste of bamboo pulp fibers.

When the bamboo pulp fiber block is transported to the opening cylinder 11, the lower pressing plate 13 on one side of the opening cylinder 11 presses the bamboo pulp fiber block, thereby facilitating the bamboo pulp fiber block to enter the inside of the opening cylinder 11. The inlet 17 provided on one side of the opening cylinder 11. When the stable conveying unit 2 is conveying the bamboo pulp fiber block, the bamboo pulp fiber block enters the opening cylinder 11 from the inlet 17. First, open the lower pressing plate 13 at the inlet 17, so that the lower pressing plate 13 can press on the bamboo pulp fiber block. Then, when the bamboo pulp fiber block reaches the inlet 17, the lower pressing plate 13 presses the bamboo pulp fiber block downward.

After the opening of the bamboo pulp fiber is completed, the output table 61 in the output unit 6 is used to output the bamboo pulp fiber discharged from the outlet 18. When the bamboo pulp fiber silk group reaches the outlet 18, the output motor drives the output roller shaft 62 to rotate, the output roller shaft 62 drives the tapered rod 63 on the side thereof to rotate, thereby pushing the bamboo pulp fiber silk group at the outlet 18 outward. After the bamboo pulp fiber silk group is pushed to the output table 61, due to the tapered structure of the tapered rod 63 on the side of the output roller shaft 62, the silk group can be detached and discharged along the output table 61.
