Description

Technical Field

[0001] The present invention relates to the technical field related to raw bamboo processing, in particular to a raw bamboo processing device for bamboo pulp processing. Background Art

[0002] Bamboo pulp is made from bamboo species such as moso, nanmu, and tsaoko, using chemical or mechanical methods. my country boasts abundant bamboo resources, with bamboo forests accounting for over a quarter of the world's total. In 2021, bamboo production reached 3.256 billion pieces, providing ample raw material for bamboo pulp production. Currently, bamboo pulp production is gradually transitioning towards large-scale and environmentally friendly production, and as the technology matures, it is expected to expand its application in green packaging, household paper, and other areas, becoming a key direction in sustainable papermaking.

[0003] Existing bamboo pulp processing technology focuses on fiber protection and efficient processing. First, a cleaning component removes impurities, followed by a degreasing pretreatment using an alkaline solution combined with a surfactant. Some processes incorporate high-temperature saturated steam for sterilization and mildew prevention, reducing the risk of subsequent contamination. Subsequently, the raw bamboo undergoes a steaming component using a sulfate or caustic soda process to soften the fibers at high temperatures while retaining their natural strength. A water spray component then evenly impregnates the bamboo. The steamed bamboo is then cut into appropriate lengths using a cutting component and then ground sideways by a grinding mechanism, avoiding excessive fiber damage caused by traditional slicing.

[0004] However, during the operation, the raw bamboo is transported from the place of production to the nearest workshop for bamboo pulp processing. The external dirt of the bamboo body is cleaned in a cleaning pool or by spraying. This process has a certain cleaning effect on the dirt attached to the surface, but the cleaning effect on the soil attached after mechanical squeezing is poor. After repeated cleaning, there are still residues on the surface or in the gullies, and the surrounding open environment has external debris falling or dirt deposited. When working in a small workshop, it is necessary to manually put the raw bamboo into the cleaning component to roll or rinse. The rinsing effect is poor, the manual labor intensity is high and the efficiency is low. In addition, in the process, steaming is performed first and then cutting. The steaming efficiency of the whole raw bamboo is lower than that of cutting into bamboo chips. Some raw bamboos have a large overall curvature and the width of the cut bamboo chips is different. During the subsequent steaming, the steaming effect of bamboo chips of different sizes is difficult to control. Summary of the Invention

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the products of the present invention are conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0021] In view of the current existing technology, during the operation, the raw bamboo is transported from the place of production to the nearest workshop for bamboo pulp processing, and the external dirt of the bamboo body is cleaned in a cleaning pool or by spraying. This process has a certain cleaning effect on the dirt attached to the surface, but the cleaning effect on the soil attached after mechanical extrusion is poor. After repeated cleaning, there are still residues on the surface or in the gullies, and the surrounding open environment has external debris falling or dirt deposited. When working in a small workshop, it is necessary to manually put the raw bamboo into the cleaning component to roll or rinse. The rinsing effect is poor, the manual labor intensity is high and the efficiency is low. In addition, in the process, steaming is performed first and then cutting. The steaming efficiency of the whole raw bamboo is lower than that of cutting into bamboo chips. Some raw bamboos have a large overall curvature and the width of the cut bamboo chips is different. During the subsequent steaming, the steaming effect of bamboo chips of different sizes is difficult to control.

[0022] like Figure 1-7 As shown, an embodiment of the present invention provides a raw bamboo processing device for bamboo pulp processing, which includes three parts: an assembly cover 1, a main body tube 2 and a stabilizing component 3.

[0023] Among them, the assembly cover 1 is arranged on the outside of the main cylinder 2 and is wrapped as a whole by the lower arc shell 11 and the movable shell 12. The assembly cover 1 is used for external protection of the main cylinder 2 during operation to prevent external debris from contaminating the interior and forming a semi-enclosed space. The outside is disassembled and installed in the interlocking groove 14 through the fixing plate 15; the main cylinder 2 structure as a whole is detachably connected to the subsequent steaming equipment. The main cylinder 2 is used to transport the raw bamboo in a step-by-step manner and clean it during transportation, and cut it into pieces at the tail end of the device; the stabilizing component 3 is arranged on the upper half of the main cylinder 2. The stabilizing component 3 is used to cover and position raw bamboo of different diameters, so that the raw bamboo is on a unified central axis as a whole inside the main cylinder 2, to avoid excessive bumps and damage to the raw bamboo during transportation and cleaning.

[0024] Furthermore, in order to improve the loading and conveying efficiency of the raw bamboo and correct the curvature before cutting, a transmission structure is formed by mutually engaging multiple sets of transmission screws 16 with driven gears 211 distributed in the lower half of the stepping channel 21. The transmission gear ring 173 evenly distributes the power transmitted by the stepping motors 171 on both sides of the docking base 17 through the external gear 172, and the transmission gear ring 173 drives multiple sets of transmission tooth grooves 161 to rotate synchronously, thereby driving the driven gear 211 to rotate inward to form a transportation channel. Under the action of gravity, the raw bamboo and the driven gear 211 are in hard contact to form a transmission. The connecting plate 31 tightly connected by the return spring 34 is pressed against the inside of the stepping channel 21 along the movable groove 213. The external connecting plate 31 and the connecting shaft 32 limit the lifting amplitude of the rubber wheel 33 in a single area while moving in conjunction with each other. The raw bamboo flows into the interior along the undulating waves to form an extrusion correction to ensure uniform curvature.

[0025] When in use, one end of the raw bamboo is inserted into the interior of the step channel 21, and the space is opened by squeezing the inlet plate 331 through the raw bamboo, and the rubber wheel 33 near the opening is lifted. Subsequently, the rubber wheel 33 is lifted in succession under the linkage of the connecting plate 31 and contacts and presses with the upper half of the raw bamboo. The pressure of the upper half causes the bent part of the raw bamboo to return to the axis. During the continuous transportation process, the raw bamboo is gradually transported from the outside to the interior of the step channel 21. When the part of the raw bamboo is included in the step channel 21 and is transported by the driven gear 211 to pass through the discharge channel 22, the raw bamboo is cut into bamboo pieces of the same width by the cutter 221. When the bamboo node is about to be cut, the bamboo node is pierced and broken by the node breaking cone 222 to avoid cutting jam.

[0026] Furthermore, in order to achieve all-round cleaning of the original bamboo, it is ensured that the stubborn stains attached to the surface of the original bamboo can be effectively cleaned.

[0027] Specifically, if Figure 2-5 As shown, the main cylinder 2 is in an I-shape as a whole, a driven gear 211 is provided inside the cylinder wall of the main cylinder 2, a drainage groove 212 is provided inside the cylinder wall of the main cylinder 2, a driven gear 211 is provided inside the cylinder wall of the main cylinder 2, the driven gears 211 are evenly distributed in the lower half of the stepping channel 21, the drainage grooves 212 are in multiple groups and evenly distributed outside the cylinder wall of the stepping channel 21, a discharge channel 22 is provided outside the tail of the stepping channel 21, and the inside of the discharge channel 22 is conical with cutters distributed circumferentially 221, a breaking cone 222 is provided on the outside of the cutter 221, a rubber ring 223 is provided at the connection between the discharge channel 22 and the assembly cover 1, a cleaning pipe network 23 is provided on the outside of the stepping channel 21, the cleaning pipe network 23 is a mesh cylinder as a whole and is connected to the stepping channel 21, the cleaning pipe network 23 extends to the inside of the stepping channel 21 and is provided with a booster nozzle 231, there are multiple groups of booster nozzles 231 and they are evenly distributed on the inside of the stepping channel 21, and a water pump 232 is connected to the outside of the cleaning pipe network 23.

[0028] Among them, the assembly cover 1 and the main barrel 2 are assembled into a whole and form a semi-enclosed space. The inside of the stepping channel 21 is a cleaning space, and the space between the assembly cover 1 and the main barrel 2 is a buffer space, which is in a relatively closed state. After the outside of the transmission screw 16 in the buffer space is attached with mud and dirt, it is restored to cleanliness under the continuous flushing of the drainage trough 212.

[0029] Specifically, if Figure 2 As shown, under the step-by-step transportation of the main tube 2, the bamboo body gradually enters the interior of the main tube 2. At this time, the water pump 232 is turned on to pump clean water into the cleaning pipe network 23. Through the transportation and pressurization of the cleaning pipe network 23, the clean water is ring-shapedly ejected to the surface of the bamboo body through the booster nozzle 231. The booster nozzles 231 in each annular cleaning area are staggered with each other to comprehensively clean all positions on the surface of the original bamboo. After the cleaning, the original bamboo is cut by the cutter 221 and the node-breaking cone 222 after passing through the cleaning area, and then separated to avoid secondary pollution caused by repeated flushing. The cleaning water is discharged from the inside of the step channel 21 through the drain trough 212, and finally discharged through the drain bucket 13. The role of the cleaning water is to circulate water for stubborn mud and dirt. The flushed muddy water can be recycled after sedimentation and filtration. It should be noted that the circulating water requires multi-layer filtration to avoid clogging of the booster nozzle 231 caused by internal mud and sand.

[0030] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
