Description

Technical Field

[0001] This application relates to the field of bamboo fiber production technology, and in particular to a bamboo fiber production equipment, system and method. Background Technology

[0002] Bamboo fiber, as a natural and environmentally friendly fiber, is characterized by its excellent breathability, strong moisture absorption and wicking ability, and superior antibacterial properties, and is widely used in textiles, home textiles, and other fields. Currently, the extraction of bamboo fiber is mainly divided into chemical and physical methods. Among them, the physical method has become the mainstream technology for the production of textile-grade bamboo fiber because it can retain the natural characteristics of bamboo fiber to the greatest extent.

[0003] In the physical extraction of bamboo fiber, the performance of key equipment directly determines the final quality of the fiber. However, existing equipment and processes have significant technical defects: current methods extract bamboo fibers through physical processes such as "explosive crushing" or "crushing and decomposition." These methods are difficult to precisely control the force applied to the bamboo raw material, easily leading to large fluctuations in the diameter and length of the final bamboo fiber and poor specification consistency. This instability directly triggers a series of problems in subsequent textile processes: for example, a surge in yarn breakage during spinning, reduced production efficiency, and fabric downgrading. Ultimately, the increased defect rate and rework costs result in uncontrolled production costs across the entire chain.

[0004] Therefore, how to design a bamboo fiber production scheme that can accurately control bamboo fiber specifications and improve fiber spinnability has become a technical problem that urgently needs to be solved in the existing physical bamboo fiber production field. Summary of the Invention

[0057] See Figures 1-4 As shown, Figure 1 This is a schematic diagram of the bamboo fiber production equipment provided in the embodiments of this application. Figure 2 for Figure 1 Top view. Figure 3 for Figure 1 The right-side view. Figure 4 for Figure 1 The left-hand view shows a bamboo fiber production device including a raw material pushing system and a raw material cutting system. Specifically, the raw material pushing system includes a raw material trough 1000 and a pushing mechanism. The raw material trough 1000 is used to hold bamboo raw materials 8000 and has a discharge port 1001. The pushing mechanism includes a pushing part 2001 movably disposed within the raw material trough 1000. The raw material cutting system includes a cutter base 3000 and a cutting mechanism 4000 connected to the cutter base 3000. The cutter base 3000 has a cutting space, and the discharge port 1001 of the raw material trough 1000 faces the cutting space. During operation, the pushing part 2001 can push at least a portion of the bamboo raw materials 8000 along the raw material trough 1000 into the cutting space, and the cutting mechanism 4000 is used to cut the bamboo raw materials 8000 within the cutting space.

[0058] The aforementioned cutting space refers to a specific area in the bamboo fiber production equipment used for cutting bamboo raw materials. It is located on the cutter base 3000 and specifically formed in the through groove 3001 of the cutter base 3000. Its opening is corresponding to the discharge port 1001 of the raw material tank 1000. It can accommodate the bamboo raw materials pushed out by the pusher 2001 from the discharge port 1001 of the raw material tank 1000. It provides a fixed working environment for the cutting mechanism 4000 to perform stable and precise cutting of bamboo raw materials within a preset range, ensuring that the cutting action is carried out in an orderly manner.

[0059] The bamboo raw material 8000 is integrated into a continuous process from placement to pushing and then to cutting, which effectively reduces the downtime during the material transportation process and improves production efficiency. At the same time, the design of the discharge port 1001 facing the cutting space and the pusher 2001 pushing in a directional manner can ensure that the bamboo raw material 8000 enters the cutting area accurately, making the cutting mechanism 4000 cut the raw material more stable and uniform, thereby reducing material waste and improving the initial processing quality of bamboo fiber.

[0060] This equipment, through the design of a raw material pushing system and a raw material cutting system, achieves a continuous operation of bamboo raw material 8000 from placement and pushing to cutting, effectively reducing raw material transportation downtime and improving production efficiency. The discharge port 1001 of the raw material trough 1000 is set to correspond to the cutting space, and the pushing part 2001 of the pushing mechanism pushes in a directional manner, ensuring that the bamboo raw material 8000 accurately enters the cutting area, allowing the cutting mechanism 4000 to stably and evenly cut the raw material. This solves the technical problem of large fluctuations in the diameter and length of bamboo raw fibers and poor specification consistency caused by the difficulty in accurately controlling the force in existing equipment. It improves the specification stability and spinnability of bamboo raw fibers, reduces raw material waste, and lowers the breakage rate and defect rate of subsequent textile processes, thereby controlling the production cost of the entire chain.

[0061] In some embodiments of this application, reference is made to the appended specification. Figures 5-7 , Figure 5 This is the first assembly diagram of a portion of the bamboo fiber production equipment provided in the embodiments of this application. Figure 6 This is the second assembly diagram of a portion of the bamboo fiber production equipment provided in the embodiments of this application. Figure 7 for Figure 6 A structural schematic diagram from another perspective. The cutting mechanism 4000 shown specifically includes a drive motor 4001, a transmission component, and a cutting tool 4002. The cutting tool 4002 is movably connected to one side of the cutting tool base 3000, and the drive end of the drive motor 4001 is connected to the cutting tool 4002 through the transmission component. The drive motor 4001 is used to drive the transmission component to move so that the cutting tool 4002 reciprocates within the cutting space.

[0062] The drive motor 4001 can stably transmit power through the transmission components, enabling the cutter 4002 to perform regular reciprocating motion within the cutting space, thereby continuously and efficiently cutting the bamboo raw material 8000 that has entered the cutting space, ensuring the consistency of the cutting action and the cutting efficiency.

[0063] In some embodiments of this application, reference is made to the appended specification. Figure 3 and attached Figure 8 , Figure 8 This is the third assembly diagram of a portion of the bamboo fiber production equipment provided in this application embodiment. The cutter base 3000 shown is specifically configured with a through groove 3001, within which a cutting space is formed. The opening of the through groove 3001 corresponds to the discharge port 1001. A movable guide rail 5000 is provided on one side of the cutter base 3000. The cutter 4002 is movably connected to the movable guide rail 5000 via a slider. The movement trajectory of the cutter 4002 within the cutting space is located between the opening of the through groove 3001 and the discharge port 1001.

[0064] The alignment of the opening of the through groove 3001 with the discharge port 1001 ensures that the bamboo raw material 8000 accurately enters the cutting space. The cooperation between the movable guide rail 5000 and the slider makes the movement of the cutter 4002 more stable and smooth. The reasonable setting of the movement trajectory of the cutter 4002 allows the raw material to be cut in time during the pushing process, avoiding the problem of inaccurate cutting caused by the deviation of the raw material.

[0065] In some embodiments of this application, the transmission component is specifically configured to include an eccentric wheel 4003 and a connecting rod 4004. One end of the connecting rod 4004 is rotatably connected to the cutter 4002, and the other end of the connecting rod 4004 is rotatably connected to the eccentric wheel 4003. The drive end of the drive motor 4001 is connected to the eccentric wheel 4003.

[0066] When the eccentric wheel 4003 rotates under the drive of the drive motor 4001, it can convert the circular motion into the reciprocating motion of the connecting rod 4004, which in turn drives the cutter 4002 to achieve the cutting action. This transmission structure is simple and compact, has high transmission efficiency, and good stability during operation, which can reduce the probability of equipment failure.

[0067] In some embodiments of this application, the pushing mechanism specifically includes a pushing module 2002, and a pushing part 2001 is disposed on the pushing module 2002. The pushing module 2002 is used to drive the pushing part 2001 to move along the edge of the raw material tank 1000.

[0068] Among them, the push module 2002 serves as the core of the power output of the push mechanism. Specifically, it can be implemented by combining a servo motor and a lead screw module. It is fixedly connected to the push unit 2001 and establishes a signal connection with the control processing unit of the sensing system. The servo motor can provide a stable and controllable driving force. The lead screw module converts the rotational motion into linear motion, driving the push unit 2001 to move smoothly and uniformly along the edge of the raw material groove 1000. The pushing speed and pushing distance can be adjusted according to the motion status information of the cutter 4002 transmitted by the control processing unit to ensure that the bamboo raw material 8000 is accurately and evenly pushed into the cutting space, thereby achieving the matching of the pushing action and the cutting action.

[0069] The push module 2002 can provide a stable driving force for the push unit 2001, so that the push unit 2001 moves at a constant speed along the edge of the raw material groove 1000, thereby ensuring that the bamboo raw material 8000 is pushed evenly into the cutting space, avoiding the situation where the raw material accumulates or is not pushed in place due to uneven pushing force or unstable speed.

[0070] In some embodiments of this application, the raw material cutting system is specifically configured to further include a sensing system, which includes a control processing unit and a detection unit. The detection unit is used to detect the movement state of the tool 4002. The detection unit is connected to the control processing unit, and the control processing unit is connected to the push module 2002.

[0071] The detection unit can monitor the movement status of the tool 4002 in real time and transmit the information to the control processing unit. The control processing unit can adjust the pushing speed of the push module 2002 according to the status of the tool 4002 to realize the pushing and cutting work, prevent the raw materials from accumulating in the cutting space or the cutting from being delayed, and improve the automation level and production coordination of the equipment.

[0072] In some embodiments of this application, the raw material pushing system is specifically configured to further include a frame disposed on one side of the tool base 3000. The frame includes a mounting frame 6000 and a shielding frame 6001. The raw material trough 1000 and the pushing mechanism are both fixed to the mounting frame 6000, and the shielding frame 6001 covers the outside of the discharge port 1001.

[0073] The mounting bracket 6000 provides a stable mounting base for the raw material tank 1000 and the pushing mechanism, ensuring that they do not shift during operation. The shielding bracket 6001 prevents bamboo chips or scraps generated during the cutting process from splashing out of the discharge port 1001, thus protecting the cleanliness of the working environment and improving operational safety.

[0074] In some embodiments of this application, a base plate 7000 is also included, and the frame and the tool base 3000 are both disposed on the base plate 7000. A reinforcing rib 3002 is provided between the tool base 3000 and the base plate 7000.

[0075] The base plate 7000 provides a unified installation platform for the entire equipment, making the layout of each component more reasonable. The setting of the reinforcing rib 3002 enhances the connection strength between the tool base 3000 and the base plate 7000, improves the stability of the tool base 3000 in the cutting operation, reduces the loosening or damage of equipment components caused by cutting vibration, and extends the service life of the equipment.

[0076] A bamboo fiber production system includes the aforementioned bamboo fiber production equipment, a bamboo straightening system, and a refrigeration system. The bamboo straightening system processes bamboo material into bamboo raw material 8000 according to the specifications of raw material tank 1000. The refrigeration system is used to freeze the bamboo material.

[0077] The bamboo straightening system allows bamboo materials to be adapted to the 1000 specification of the raw material trough, ensuring smooth subsequent raw material pushing and cutting operations. The refrigeration system freezes the bamboo materials, which can improve their processing characteristics and make them easier to cut, thereby improving the fiber extraction effect. The entire system integrates the pretreatment and cutting links to achieve continuous production, reduce connection time, and thus improve overall production efficiency and product quality.

[0078] A method for producing bamboo fiber, applicable to the aforementioned bamboo fiber production system, comprising:

[0079] Step S1: Using a bamboo straightening system, the bamboo material is processed into bamboo raw material 8000 according to the specifications of raw material trough 1000.

[0080] Specifically, the bamboo shaping system processes bamboo material into bamboo raw material 8000. This system includes a bamboo splitter, a four-sided planer, and a CNC pelletizer. The splitter breaks bamboo into long strips according to preset dimensions. The four-sided planer flattens the strips to meet dimensional accuracy requirements. The CNC pelletizer cuts the flattened strips into pieces with a length of 35mm, a width of 22mm, and a thickness of 5mm to 9mm, matching the specifications of the raw material trough 1000. The thickness of the bamboo pieces is set to a range of 5mm to 9mm to accommodate natural variations in the bamboo's length and thickness. This multi-equipment processing ensures that the length, width, and basic thickness of the bamboo raw material 8000 meet the equipment compatibility requirements of subsequent processes, preventing processing bottlenecks or uneven finished product quality due to irregular raw material dimensions. This provides standardized raw material assurance for the smooth operation of the entire production process.

[0081] Step S2: Freeze the bamboo raw material 8000 using a refrigeration system;

[0082] Specifically, the processed bamboo raw material 8000 is initially frozen using the aforementioned refrigeration system. First, water is sprayed onto the surface of the bamboo strips. Then, the bamboo strips are placed in a stainless steel mold measuring 300mm in length, 22mm in width, and 35mm in height. The mold containing the bamboo strips is then placed in a cold storage compartment of the refrigeration system with a temperature set between -20 and -40 degrees Celsius. The freezing time is controlled between 3 and 24 hours. The water spraying treatment forms a thin ice protective layer on the surface of the bamboo strips, and the low-temperature freezing allows the internal moisture to condense, enhancing the rigidity and integrity of the overall bamboo structure and reducing breakage and loss of bamboo fibers during subsequent cutting. Simultaneously, the mold's limiting function prevents deformation of the bamboo strips during freezing, ensuring the stability of the raw material's shape.

[0083] Step S3: Place the refrigerated bamboo raw material 8000 into the raw material tank 1000, start the pushing mechanism and raw material cutting system until the raw material of the first specification is obtained through cutting.

[0084] Specifically, after the refrigerated bamboo raw material 8000 is demolded from the mold, it is immediately placed in the raw material tank 1000 of the equipment, which is maintained at a temperature of 0 to 3 degrees Celsius. This temperature environment prevents the bamboo slices from thawing and softening. The pushing mechanism and the raw material cutting system are then activated to perform slicing processing. The equipment's cutter head is equipped with a photoelectric switch sensor. When the cutter leaves the upper edge of the lower blade, the photoelectric switch sensor sends a trigger command. The servo motor, in conjunction with the lead screw module, drives the push rod to push the bamboo slices. The pushing distance is set to 0.05 to 0.15 mm each time, depending on the different specifications required. The cutter is driven by a lower motor through an eccentric wheel 4003, which drives a connecting rod 4004 and a fisheye bearing. With the help of the cutter head and the linear guide rail of the slider, the cutter achieves reciprocating motion, precisely slicing the bamboo slices until the first-grade raw material is obtained. This step, through the low-temperature environment and the photoelectric sensor servo drive, ensures the stability of the raw material during slicing. The precise control of the pushing distance ensures the uniformity of the thickness of the first-grade raw material. The reciprocating motion structure of the cutter improves slicing efficiency and reduces raw material waste.

[0085] Step S4: Put the raw materials processed once into the refrigeration system again for freezing;

[0086] Specifically, after the initial slicing process, the raw material is sprayed with water and placed in a stainless steel mold measuring 300mm long, 35mm wide, and 26mm high. The mold is then placed in a refrigerator compartment with a temperature set between -20 and 40 degrees Celsius for approximately 3 hours. The second water spray replenishes the surface moisture of the raw material, and the second freezing further strengthens its structural rigidity, preventing deformation or fiber adhesion during subsequent shredding. The mold's dimensional adaptability ensures the raw material maintains a regular shape during freezing, supporting the precision of subsequent shredding.

[0087] Step S5: Place the primary processed raw material after re-refrigeration into the raw material tank 1000, and start the pushing mechanism and raw material cutting system until the secondary processed raw material of the second specification is obtained.

[0088] Specifically, the primary processed raw material, after being refrigerated again, is kept in a cold storage environment of 0 to 3 degrees Celsius and placed stably in the raw material tank 1000 of the equipment. The pushing mechanism and the raw material cutting system are then activated to perform shredding. The working principle is the same as the initial slicing. The photoelectric switch sensor on the cutter head detects the position of the cutter in real time. When the cutter leaves the upper edge of the lower blade, a command is sent. The servo motor, in conjunction with the lead screw module, pushes the push rod to precisely advance 0.05 to 0.15 mm each time. The cutter moves back and forth along the linear guide rail of the cutter head and the slider through the linkage of the motor eccentric wheel 4003, the connecting rod 4004, and the fisheye bearing, shredding the primary processed raw material until secondary processed raw material (bamboo shreds) with a length of 35 mm and a diameter of 0.05 to 0.15 mm, meeting the second specification, is obtained. This step adopts a mature cutting working principle, reducing the difficulty of equipment debugging and operation. The low temperature environment effectively prevents the primary processed raw material from thawing, and the precise pushing and cutting actions ensure the consistency of the diameter and the stability of the length of the bamboo shreds, improving the finished product qualification rate of the secondary processed raw material.

[0089] After step S5, the bamboo shreds obtained from the cutting process are removed from the cold storage and allowed to thaw naturally at room temperature. Once the bamboo shreds are completely thawed and no residual frost remains on the surface, the extraction of bamboo shreds is complete. Natural thawing avoids damage to the internal fiber structure of the bamboo shreds caused by sudden temperature changes, ensuring the integrity and natural properties of the bamboo fibers. The thawed bamboo shreds are stable, facilitating the subsequent bio-softening process. Furthermore, room temperature thawing requires no additional energy, reducing production costs.

[0090] Finally, the thawed bamboo fibers undergo a bio-softening process. Through the catalytic action of biological agents, lignin and hemicellulose in the bamboo fibers are decomposed, effectively separating the fibrous and non-fibrous components. After subsequent processing such as filtration and washing, the bamboo fiber is extracted. This bio-softening process is gentle and environmentally friendly, preserving the natural physicochemical properties of the bamboo fiber. The extracted bamboo fiber retains good strength and flexibility, enhancing the product's application value. Furthermore, the use of biological agents aligns with green production principles, reducing environmental pollution.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
