Description

Technical Field

[0001] This invention belongs to the field of bamboo fiber knitted fabric processing technology, and particularly relates to a manufacturing process for sun-protective bamboo fiber knitted fabric. Background Technology

[0002] Sunscreen bamboo fiber knitted fabric is made from bamboo as raw material. Cellulose is extracted and spun through a special process, and then processed through knitting. It is a fabric with sunscreen function. When manufacturing sunscreen bamboo fiber knitted fabric, the bamboo fiber raw material needs to be pretreated. The treatment method is to soak the bamboo fiber in a UV absorber extracted from natural plants to bind the molecules and enhance its functionality.

[0003] In the current bamboo fiber processing technology system, the industry mainly adopts two technical paths for optimizing the pretreatment process: batch extraction and continuous conveying soaking. However, both have significant application limitations. Specifically, the batch extraction process involves feeding bamboo fiber raw materials into a closed reactor in batches for chemical or enzymatic hydrolysis. Its core drawback is the prominent discreteness of the processing flow. Each batch of raw materials needs to undergo independent feeding, reaction, and discharge cycles, resulting in low efficiency in the connection between various links of the production line and difficulty in achieving large-scale continuous production. In particular, it is easy to form a capacity bottleneck when processing large-volume orders.

[0004] In contrast, continuous conveying soaking technology, while constructing a dynamic processing system through devices such as conveyor belts or screw pumps to pre-treat bamboo fibers in a flowing state, theoretically improves processing continuity. However, to ensure that the fibers fully absorb the treatment solution and achieve the required modification effect, this technology must guarantee a sufficient soaking time. Limited by the balance between the fiber residence time in the equipment and the processing efficiency, existing designs have to extend the processing path by increasing the equipment volume, such as using soaking tanks tens of meters long or multi-stage series reactors. Although this solution can meet the process parameter requirements, it directly leads to a surge in equipment footprint and a significant increase in infrastructure costs. Furthermore, long-flow conveying can easily cause technical problems such as fiber breakage and differences in treatment solution concentration gradients, ultimately creating a passive situation of "trading space for time," which restricts the flexibility and economy of the production line. Summary of the Invention

[0005] This invention provides a manufacturing process for sun-protective bamboo fiber knitted fabric, aiming to solve the problems of low processing continuity of bamboo fiber in the batch extraction method mentioned in the background art, and the inconvenience of continuous conveying and soaking bamboo fiber, which requires a large volume of soaking equipment to extend the processing production line in order to ensure sufficient soaking time.

Detailed Implementation

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a manufacturing process for sun-protective bamboo fiber knitted fabric, such as... Figure 1-11 As shown, the manufacturing process of sun-protective bamboo fiber knitted fabric includes: processing bamboo fiber fabric using a sun-protective bamboo fiber knitted fabric manufacturing device, the sun-protective bamboo fiber knitted fabric manufacturing device including: a box body 1; a support shaft 2 rotatably installed on the top of the box body 1, a support box 3 installed on the top of the support shaft 2; support rods 4 respectively fixed on both sides of the support box 3, and a storage box 5 for storing bamboo fiber fixed on each of the two support rods 4, the storage box 5 having mesh holes that allow natural plant-extracted ultraviolet absorbers to pass through; and an isolation structure set on the box body 1 for isolating the soaking environment.

[0021] In this embodiment, when in use, bamboo fiber is placed in storage box 5. During the processing, the natural plant-extracted ultraviolet absorber comes into full contact with the bamboo fiber through the mesh of storage box 5. Rotating the support shaft 2 drives the support box 3, support rod 4 and storage box 5 to rotate, realizing the dual-station switching of the two storage boxes 5. By setting up a rotatable support shaft 2, a support box 3, and a support rod 4, as well as a storage box 5 with mesh, the bamboo fiber can be more evenly contacted with the natural plant-extracted ultraviolet absorber during processing, effectively improving the soaking effect and enhancing the sun protection performance of the bamboo fiber fabric. It also facilitates continuous operation by switching work stations. At the same time, the isolation structure can provide protection for the soaking environment, avoid interference from external factors in the processing, and ensure the stability of processing quality.

[0022] In a further preferred embodiment of the present invention, the isolation structure includes a threaded rod 6 rotatably mounted on the housing 1, the threaded rod 6 having two threaded segments in opposite directions, adjusting blocks 7 threadedly fitted onto the two threaded segments respectively, a top cover 8 and a bottom box 9 respectively fixed to the two adjusting blocks 7, the bottom box 9 being used to hold a natural plant-extracted ultraviolet absorber, the top cover 8 being used to seal the bottom box 9, the top cover 8 and the bottom box 9 being able to be fitted onto any of the storage boxes 5 to isolate the immersion environment, and an air pressure regulating mechanism provided on the support box 3 for regulating the air pressure of the immersion environment.

[0023] In this embodiment, during operation, the threaded rod 6 is rotated first. Since the threaded rod 6 has two threaded sections in opposite directions, when the threaded rod 6 rotates, the two adjusting blocks 7 will move towards or away from each other along the threaded rod 6. When the adjusting blocks 7 move towards each other, the top cover 8 and the bottom box 9 fixed on the two adjusting blocks 7 will move closer. The top cover 8 and the bottom box 9 are fitted outside any storage box 5, isolating the bamboo fiber in the storage box 5 from the external environment and forming an independent soaking environment. At this time, the air pressure regulating mechanism set on the support box 3 starts to work. First, the air in the fiber tube is evacuated and then the ultraviolet absorber extracted from natural plants is injected. Then, the pressure is increased. After the soaking treatment is completed, the ultraviolet absorber extracted from natural plants is discharged first, and the excess liquid in the fiber tube is discharged again by increasing the pressure. When it is necessary to change the storage box 5 for soaking, the threaded rod 6 is controlled to rotate in the opposite direction, so that the adjusting block 7 drives the top cover 8 and the bottom box 9 to separate. The support shaft 2 is rotated to realize the switching of the work position. Then the above content is repeated. By cooperating with the threaded rod 6 and the adjusting block 7, the positions of the top cover 8 and the bottom box 9 can be flexibly controlled, allowing them to be fitted over any storage box 5. This achieves independent isolation of the bamboo fiber soaking environment in different storage boxes 5, avoiding mutual interference between bamboo fibers from different batches or locations during the soaking process, and improving the accuracy and stability of the soaking. By setting the bottom box 9 to hold the ultraviolet absorber, and the top cover 8 sealing the bottom box 9 to form an independent space, combined with the air pressure regulating mechanism to regulate the air pressure of the soaking environment, more controllable conditions are provided for the soaking of bamboo fibers, which helps to improve the absorption efficiency of ultraviolet absorbers by bamboo fibers.

[0024] In a further preferred embodiment of the present invention, the air pressure regulating mechanism includes a connecting plate 14 rotatably mounted on the top of the support box 3, a pump 15 fixed on the top of the connecting plate 14, a connecting pipe 16 mounted on the pump 15 for providing an airflow output channel, and a side pipe fixed on the connecting pipe 16 for providing an airflow input channel. Both the connecting pipe 16 and the side pipe are equipped with an electric valve and a one-way valve to limit the direction of gas flow. The pump 15, in conjunction with the connecting pipe 16, is used to extract air to reduce the air pressure in the soaking environment and expel air from the bamboo fiber tubes. The pump 15, in conjunction with the side pipe, is used to inflate air to increase the air pressure in the soaking environment, allowing the natural plant-extracted ultraviolet absorber to quickly enter the fiber tubes. The top cover 8 is equipped with a pressure gauge 17 for monitoring air pressure. A fixing frame 12 is fixed on the box 1, and the connecting plate 14 is fixedly connected to the fixing frame 12.

[0025] In this embodiment, during the bamboo fiber soaking process, when it is necessary to reduce the ambient air pressure to expel air from the bamboo fiber tubes, the air pump 15 installed on the connecting plate 14 at the top of the support box 3 is started, and the electric valve on the connecting pipe 16 is opened while the electric valve on the side pipe is closed. At this time, gas can only be pumped through the connecting pipe 16 by the air pump 15 (which uses a pump body with switchable exhaust ports, i.e., a pump whose inlet and outlet ports can be switched by forward and reverse rotation; this type of pump includes a casing, a wall panel, and two rotors installed inside the casing. The rotors are identical two-lobe rotors that mesh with each other. A gearbox and a reversible gearbox are installed sequentially at the rear end of the wall panel). The motor and rotor are connected to the motor drive through gears in the gearbox and rotate in opposite directions. When the rotation direction of the motor changes from forward to reverse, the exhaust direction changes (the air inlet and exhaust port switch) and is drawn out, which reduces the air pressure of the soaking environment formed by the top cover 8 and the bottom box 9. When it is necessary to increase the air pressure of the soaking environment to promote the rapid entry of the natural plant-extracted ultraviolet absorber into the fiber tube, the electric valve on the connecting pipe 16 is closed and the electric valve on the side pipe is opened. The air pump 15 inflates the soaking environment through the side pipe to increase the ambient air pressure. At the same time, the air pressure gauge 17 set on the top cover 8 monitors the air pressure in the soaking environment in real time. Through the cooperation of air pump 15, connecting pipe 16 and side pipe, as well as the control of gas flow direction by electric valve and one-way valve, the air pressure of the bamboo fiber soaking environment can be flexibly adjusted. Lowering the air pressure can effectively expel air from the bamboo fiber tubes, preventing air from hindering the ultraviolet absorber from entering the fiber interior. Increasing the air pressure can promote the ultraviolet absorber to enter the fiber tubes quickly, improving the absorption efficiency of the bamboo fiber for the ultraviolet absorber, thereby improving the processing efficiency of bamboo fiber fabric. The air pressure gauge 17 set on the top cover 8 can provide real-time feedback of air pressure information, making it convenient for operators to adjust the air pressure parameters in a timely manner, ensuring the stability and controllability of the soaking process.

[0026] In a further preferred embodiment of the present invention, the bottom of the top cover 8 is provided with a first sealing ring 10 that can contact the top of the bottom box 9, the top cover 8 is provided with a snap fastener that can be fitted over the support rod 4, and the support rod 4 is fitted with a second sealing ring 11 that can contact the inner wall of the snap fastener. Both the first sealing ring 10 and the second sealing ring 11 are used to prevent air leakage.

[0027] In this embodiment, when isolating the bamboo fiber soaking environment, as the top cover 8 moves downward and approaches the bottom box 9, the first sealing ring 10 will gradually come into close contact with the top of the bottom box 9. When the top cover 8 moves to the appropriate position and the buckle is fitted onto the support rod 4, the second sealing ring 11 will fit tightly against the inner wall of the buckle, effectively preventing gas leakage in the soaking environment. By setting the first sealing ring 10 and the second sealing ring 11, the sealing between the top cover 8 and the bottom box 9, as well as between the top cover 8 and the support rod 4, is enhanced, creating a reliable sealed space for the bamboo fiber soaking environment, so that the air pressure regulating mechanism can more stably control the air pressure of the soaking environment.

[0028] In a further preferred embodiment of the present invention, an extension plate 18 is fixed on the housing 1, and a first limiting guide block 19 fixedly connected to the bottom box 9 is slidably installed on the extension plate 18. The extension plate 18, in conjunction with the first limiting guide block 19, is used to limit the movement path of the bottom box 9 to prevent overturning. A second limiting guide block 20 connected to the top cover 8 is slidably installed on the fixing frame 12 to limit the movement path of the top cover 8 to prevent tilting.

[0029] In this embodiment, during the operation of the device, when it is necessary to soak the bamboo fiber and control the movement of the top cover 8 and the bottom box 9 to create an isolated soaking environment, during the movement of the bottom box 9, the first limiting guide block 19 slides along the set track of the extension plate 18, thereby limiting the bottom box 9 to only move along the path specified by the extension plate 18, preventing the bottom box 9 from overturning during the movement. At the same time, when the top cover 8 moves, the second limiting guide block 20 connected to the top cover 8 slides on the fixed frame 12, and the second limiting guide block 20 moves along the track of the fixed frame 12 to provide guidance for the movement of the top cover 8. By setting the extension plate 18 in conjunction with the first limiting guide block 19, the movement path of the bottom box 9 is effectively limited, reducing the risk of the bottom box 9 tipping over and ensuring the stability of the device operation. By setting the fixing frame 12 and the second limiting guide block 20, the movement of the top cover 8 is guided, so that the top cover 8 always maintains the correct posture during the movement and can accurately dock with the bottom box 9, avoiding problems such as poor sealing caused by the tilt of the top cover 8.

[0030] In a further preferred embodiment of the present invention, a drive shaft 22 and a driven shaft 23 are rotatably mounted inside the housing 1. A first motor 31 is fixed inside the housing 1, and a connecting gear is fixed on the output shaft of the first motor 31. A second gear 25 and a first gear 24 are respectively fixed on the drive shaft 22 and the driven shaft 23. An adjusting frame 26 is slidably mounted inside the housing 1, and a transmission gear 27 is rotatably mounted on the adjusting frame 26 for adjusting the transmission state of the first motor 31 with the drive shaft 22 and the driven shaft 23 respectively. The driving gear 27 meshes with the connecting gear. An electric telescopic rod 28, which is connected to the adjusting frame 26, is fixed inside the housing 1. The electric telescopic rod 28, in conjunction with the adjusting frame 26, is used to adjust the meshing state of the transmission gear 27 with the first gear 24 and the second gear 25. A first bevel gear 29 is fixed on both the driven shaft 23 and the support shaft 2. The two first bevel gears 29 mesh with each other. A second bevel gear 30 is fixed on both the driving shaft 22 and the threaded rod 6. The two second bevel gears 30 mesh with each other.

[0031] In this embodiment, when it is necessary to drive the threaded rod 6 to rotate to adjust the position of the top cover 8 and the bottom box 9, the first motor 31 is started. The output shaft of the first motor 31 drives the connecting gear to rotate. At this time, the electric telescopic rod 28 is in the initial state. The transmission gear 27 on the adjusting frame 26 meshes with the second gear 25 on the drive shaft 22. The connecting gear transmits power to the second gear 25 through the transmission gear 27, thereby driving the drive shaft 22 to rotate. The second bevel gear 30 on the drive shaft 22 rotates accordingly, thereby driving the threaded rod 6 to rotate, realizing the movement operation of the top cover 8 and the bottom box 9. When it is necessary to drive the support shaft 2 to rotate, the electric telescopic rod 28 is extended to push the adjusting frame 26 to slide inside the box 1, so that the transmission gear 27 meshes with the first gear 24 on the driven shaft 23. The first motor 31 continues to run. The connecting gear transmits power to the first gear 24 through the transmission gear 27, driving the driven shaft 23 to rotate. The first bevel gear 29 on the driven shaft 23 rotates accordingly, thereby driving the support shaft 2 to rotate, realizing the work position switching. Through the cooperation of the first motor 31, connecting gear, transmission gear 27, first gear 24, second gear 25, electric telescopic rod 28, and adjusting frame 26, the purpose of flexibly switching between driving the active shaft 22 and driven shaft 23 with a single first motor 31 is achieved. This reduces the number of motors used, lowers the cost and energy consumption of the device, simplifies the structure of the device, and improves its compactness and reliability. By utilizing the meshing transmission of bevel gears (first bevel gear 29 and second bevel gear 30), power can be transmitted smoothly, realizing the power conversion between different shafts.

[0032] In a further preferred embodiment of the present invention, the storage box 5 is provided with a protective cover 32 for preventing bamboo fiber from floating. The bottom of the protective cover 32 is provided with a limiting ring 33 that extends into the storage box 5 and slides in contact with the inner wall of the storage box 5. The top of the protective cover 32 is provided with a handle 34 for providing an operating grip point. The storage box 5 is threaded with a limiting bolt that can be threadedly connected to the limiting ring 33.

[0033] In this embodiment, when bamboo fiber is placed in storage box 5 for soaking treatment, in order to prevent bamboo fiber from floating in the soaking solution, protective cover 32 is first placed above storage box 5, so that the limiting ring 33 at the bottom of protective cover 32 extends into storage box 5. After the position of protective cover 32 is determined, the limiting bolt on storage box 5 is rotated so that the limiting bolt is threadedly connected to the limiting ring 33. Through the locking action of the limiting bolt, the limiting ring 33 is fixed in storage box 5, and then the protective cover 32 is firmly installed on storage box 5, so that the protective cover 32 is aligned with the bamboo fiber to prevent it from floating. By setting up the protective cover 32, the problem of bamboo fiber easily floating when soaking in the storage box 5 is effectively solved, ensuring that the bamboo fiber can be fully submerged in the soaking solution and fully contact the natural plant-extracted ultraviolet absorber, thereby improving the absorption effect of the bamboo fiber on the ultraviolet absorber and thus enhancing the sun protection performance of the bamboo fiber fabric. The limiting ring 33 slides in contact with the inner wall of the storage box 5, which facilitates the accurate installation and adjustment of the protective cover 32. At the same time, by making the limiting bolt and the limiting ring 33 threadedly connected, the protective cover 32 can be reliably fixed to prevent it from loosening or shifting during the soaking process.

[0034] In a further preferred embodiment of the present invention, a storage tank 21 for storing ultraviolet absorbers extracted from natural plants is installed on one side of the housing 1. A water pump 39 is provided inside the storage tank 21. A three-way valve 40 is provided at both the inlet and outlet ends of the water pump 39. A first inlet pipe and a first outlet pipe are installed on the three-way valve 40 at the inlet end of the water pump 39, and a second inlet pipe and a second outlet pipe are installed on the three-way valve 40 at the outlet end of the water pump 39. The first inlet pipe is connected to the bottom tank 9, and the second outlet pipe is connected to the first inlet pipe to form a replenishment channel.

[0035] In this embodiment, during the bamboo fiber soaking process, when it is necessary to replenish the soaking liquid in the bottom tank 9, the water pump 39 in the storage tank 21 is started. At this time, the three-way valve 40 located at the inlet end of the water pump 39 is adjusted to connect the first inlet pipe with the inlet end of the water pump 39. At this time, the liquid movement path is the second inlet pipe - water pump 39 - second drain pipe - first inlet pipe. When it is necessary to extract the soaking liquid in the bottom tank 9, the three-way valve 40 is adjusted. At this time, the liquid movement path is the first inlet pipe - water pump 39 - second drain pipe. The storage tank 21 allows for centralized storage of natural plant-extracted ultraviolet absorbers, facilitating management and use. The water pump 39, in conjunction with two three-way valves 40, enables flexible control of the absorber's flow direction. By adjusting the state of the three-way valves 40, replenishment channels can be established or cut off, allowing for the replenishment and extraction of natural plant-extracted ultraviolet absorbers according to the actual needs of the soaking solution in the bottom tank 9.

[0036] In a further preferred embodiment of the present invention, the housing 1 is provided with an operating port for providing a maintenance passage, and a protective door 36 for closing the operating port is hinged to the housing 1. A retaining plate 37 is fixed on the protective door 36, and a U-shaped plate 38 that can be sleeved on the retaining plate 37 and used to stabilize the protective door 36 is slidably installed on the housing 1.

[0037] In this embodiment, when it is necessary to maintain and repair the components inside the housing 1, the operator first slides the U-shaped plate 38 on the housing 1 to disengage the U-shaped plate 38 from the clamping plate 37 on the protective door 36, thereby releasing the stability restriction on the protective door 36. Then, the operator rotates the protective door 36 through the hinge point to open the protective door 36. At this time, the operating port on the housing 1 is exposed, and the operator can perform operations such as lubrication on the gear structure inside the housing 1 through the operating port. The operation port facilitates maintenance and repair of the internal components of the housing 1 by the operator, improving the maintainability of the device. The cooperation of the clamping plate 37 and the U-shaped plate 38 provides a stable fixing method for the protective door 36. During normal operation of the device, it can effectively prevent the protective door 36 from being opened accidentally and prevent external debris from entering the housing 1.

[0038] In a further preferred embodiment of the present invention, a support frame 35 is fixedly fixed at the top of the housing 1 and rotatably sleeved outside the support shaft 2 for stabilizing the support shaft 2, and a plurality of triangular plates connected to the support shaft 2 are fixed at the bottom of the support box 3 for causing the support box 3.

[0039] In this embodiment, during the operation of the device, the support frame 35 provides radial support for the support shaft 2, limiting the swaying of the support shaft 2 in the radial direction. The triangular plate connects the support box 3 to the support shaft 2, transmitting the force on the support box 3 to the support shaft 2. By setting the support frame 35, the stability of the support shaft 2 during rotation is effectively enhanced, the radial runout of the support shaft 2 caused by rotation is reduced, the probability of wear and failure of internal components of the device caused by the instability of the support shaft 2 is reduced, and the service life of the device is extended. By setting the triangular plate, a reliable and stable support is provided for the support box 3, which can withstand the weight of the support box 3 and its internal components and various forces generated during operation, ensuring that the support box 3 is always in a stable state.

[0040] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, the storage tank 21 is provided with a refractometer for detecting the concentration of ultraviolet absorbers extracted from natural plants, and the storage tank 21 is provided with a storage hopper 41 for storing raw materials of ultraviolet absorbers extracted from natural plants. A discharge component 42 is provided between the storage hopper 41 and the storage tank 21. The discharge component 42 includes a discharge pipe fixed between the storage hopper 41 and the storage tank 21, a cylinder 43 disposed on the discharge pipe, a distribution shaft 44 rotatably installed inside the cylinder 43, and a plurality of distribution plates 45 fixed on the distribution shaft 44 and all in contact with the inner wall of the cylinder 43.

[0041] In this embodiment, during the bamboo fiber processing, the refractometer continuously monitors the concentration of the natural plant-extracted ultraviolet absorber in the storage tank 21. When the absorber concentration is detected to be lower than the set standard, the storage tank 21 needs to be replenished with raw materials. At this time, the distributing shaft 44 is rotated, and the distributing shaft 44 drives multiple distributing plates 45 to rotate inside the cylinder 43. The natural plant-extracted ultraviolet absorber raw materials in the storage hopper 41 enter the cylinder 43 through the discharge pipe. As the distributing plates 45 rotate, the raw materials are quantitatively separated and driven by the distributing plates 45, and gradually transported from one end of the cylinder 43 to the other end, and finally fall into the storage tank 21 to replenish the raw materials. When the refractometer detects that the absorber concentration has reached the appropriate standard, the distributing shaft 44 is stopped from rotating, and the discharge component 42 stops discharging. By setting up a refractometer, the concentration of the natural plant-extracted ultraviolet absorber in the storage tank 21 can be detected in real time, providing an accurate basis for timely replenishment of raw materials. This ensures that the bamboo fiber is always treated in an absorber solution of appropriate concentration, improving the absorption effect of the bamboo fiber on the ultraviolet absorber, thereby enhancing the sun protection performance of the bamboo fiber fabric. Through the cooperation of the storage hopper 41 and the discharge component 42, the storage and quantitative replenishment of raw materials are realized. The structure of the distribution shaft 44 and the distribution plate 45 allows the raw materials to enter the storage tank 21 evenly, avoiding the situation of too much or too little raw material replenishment.

[0042] In another embodiment of the present invention, a stirring shaft 46 for mixing raw materials is rotatably installed inside the liquid storage tank 21, and a second motor 47 for driving the stirring shaft 46 to rotate is fixed on the liquid storage tank 21. The output shaft of the second motor 47 is connected to the stirring shaft 46 through a coupling.

[0043] In this embodiment, after adding natural plant-extracted ultraviolet absorber raw materials into the storage tank 21, in order to fully dissolve the raw materials and mix them evenly with the original liquid in the tank, the second motor 47 is started. The second motor 47 starts to run and drives the stirring shaft 46 to rotate in the storage tank 21. During the rotation of the stirring shaft 46, the stirring blades on it will stir the liquid in the storage tank 21, causing the newly added raw materials to continuously collide and blend with the original liquid. By setting up a stirring shaft 46 in conjunction with a second motor 47, the problem of insufficient dissolution and uneven mixing of natural plant-extracted ultraviolet absorber raw materials in the storage tank 21 can be effectively solved, ensuring the uniformity of the concentration of the natural plant-extracted ultraviolet absorber solution in the storage tank 21. This helps the bamboo fiber to uniformly absorb the ultraviolet absorber during subsequent processing, improving the absorption effect of the bamboo fiber on the ultraviolet absorber, and thus enhancing the sun protection performance and quality stability of the bamboo fiber fabric.

[0044] In another embodiment of the present invention, a connecting frame 48 is fixed on the cylinder 43, a limiting cylinder 49 is fixed on the stirring shaft 46, a rotating block 50 is rotatably mounted on the connecting frame 48, an adjusting shaft 51 that movably passes through the connecting frame 48 is slidably mounted on the rotating block 50, a limiting block 52 that can extend into the limiting cylinder 49 for transmission is fixed on the adjusting shaft 51, a transmission roller is fixed on the output shaft of the second motor 47, and the transmission roller and the rotating block 50 are covered with the same rubber belt 55 for transmission.

[0045] In this embodiment, during the operation of the device, when it is necessary to link the stirring shaft 46 with the distributing shaft 44 inside the cylinder 43, the adjusting shaft 51 is first pushed to slide on the rotating block 50, so that the limiting block 52 fixed on the adjusting shaft 51 extends into the limiting cylinder 49 on the stirring shaft 46, thereby realizing the transmission connection between the stirring shaft 46 and the adjusting shaft 51. Then, the second motor 47 is started, and the output shaft of the second motor 47 drives the transmission roller to rotate. The transmission roller drives the rotating block 50 to rotate on the connecting frame 48 through the rubber belt 55, thereby driving the distributing shaft 44 to rotate, thereby realizing the discharge function. When linkage is not required, the adjusting shaft 51 is pulled to disengage the limiting block 52 from the limiting cylinder 49, thereby disconnecting the transmission connection between the stirring shaft 46 and the adjusting shaft 51. By setting up a connecting frame 48, a rotating block 50, an adjusting shaft 51, a limiting block 52, a limiting cylinder 49, and a rubber belt 55, flexible control of the transmission between the stirring shaft 46 and the distributing shaft 44 is achieved. By pushing or pulling the adjusting shaft 51, the transmission connection between the stirring shaft 46 and the adjusting shaft 51 can be easily established or disconnected. This allows the device to choose to perform only stirring or simultaneously perform stirring and discharging according to actual needs, thus improving the flexibility of the device operation and the diversity of its functions.

[0046] In another embodiment of the present invention, the rotating block 50 is provided with a sliding groove 53, and a sliding piece 54 connected to the adjusting shaft 51 is slidably installed in the sliding groove 53. The connecting frame 48 is provided with an opening, and a rubber ring that contacts the adjusting shaft 51 and is used to help stabilize the adjusting shaft 51 is fixed in the opening.

[0047] In this embodiment, during the operation of the adjusting shaft 51 to control the transmission connection or disconnection between the stirring shaft 46 and the distributing shaft 44, the adjusting shaft 51 will slide within the rotating block 50. When the adjusting shaft 51 slides, the sliding plate 54 will move accordingly within the sliding groove 53. By setting the sliding groove 53 and the sliding plate 54, the sliding of the adjusting shaft 51 is guided, making it easier for the operator to control the movement of the adjusting shaft 51. This enables the connection or disconnection of the transmission between the stirring shaft 46 and the distributing shaft 44, improving the controllability and convenience of the device operation. At the same time, it also has a limiting effect and transmits rotational force. The rubber ring can help stabilize the adjusting shaft 51 and prevent it from moving undesirably due to vibration and other factors during the operation of the device, thus ensuring the stability of the transmission control. On the other hand, the rubber ring has a certain degree of elasticity and will not cause excessive resistance to the sliding of the adjusting shaft 51 when it comes into contact with it. It can also reduce the wear between the adjusting shaft 51 and the connecting frame 48.

[0048] In another embodiment of the present invention, an ultrasonic generator is fixed on the housing 1, the vibrating rod of the ultrasonic generator extends into the bottom box 9, a support ring sleeved on the vibrating rod is fixed inside the bottom box 9, and an elastic buffer pad is provided between the support ring and the vibrating rod.

[0049] In this embodiment, during the bamboo fiber soaking process, the ultrasonic generator fixed on the box 1 is activated. The ultrasonic generator generates a high-frequency electrical signal, which is transmitted to the vibrating rod extending into the bottom box 9, causing the vibrating rod to vibrate at a high frequency. When the vibrating rod vibrates in the bottom box 9, it will cause the surrounding liquid to vibrate, generating a large number of tiny bubbles to play a mixing role. By setting up an ultrasonic generator and a vibrating rod, the cavitation effect of ultrasound can be used to improve the mixing efficiency of the soaking solution and prevent the concentration of the soaking solution near the bamboo fiber from decreasing during molecular bonding, which would affect the processing quality. The support ring fixes and supports the vibrating rod, ensuring its stability during vibration and preventing the processing effect from being affected by the vibration rod shaking. The setting of the elastic buffer pad effectively reduces the impact of vibration on the device components and reduces the risk of damage to the components due to frequent vibration.

[0050] In summary, compared with related technologies, this device facilitates the switching of the positions of the two storage boxes 5 by rotating the mounting support shaft 2, thereby assisting in the switching of workstations and enabling continuous processing. By setting up storage boxes 5 to store bamboo fiber, it is convenient to load and unload materials centrally. By setting up an isolation structure in conjunction with the air pump 15 to regulate air pressure, the absorption efficiency of bamboo fiber for absorbent can be effectively improved.

[0051] It is worth noting that all circuits, electronic components, and modules involved in this invention are existing technologies (the first motor 31 can be a NEMA 42, the second motor 47 can be a Siemens 1FT7 servo motor, and the electric telescopic rod 28 can be a Delco LT30 electric push rod).
