Description

Technical Field

[0001] This invention belongs to the technical field of textile machinery, and more specifically relates to a wet opening and feeding integrated machine, which is mainly used as a connecting device between the refining process and the drying process in a cellulose fiber production line. It can realize the integrated operation of fiber opening, preheating, conveying and cotton laying. Background Technology

[0002] Cellulose fiber is hailed as the green fiber of the 21st century. Regenerated cellulose fiber is made using N-methylmorpholine-N-oxide (NMMO) as a solvent and employing wet or dry spinning processes. The production process of green fiber is environmentally friendly and pollution-free, and the fiber itself possesses excellent wearing properties, making it widely used in the clothing and textile industry. Green fiber can be spun purely into various clothing fabrics, or blended with cotton, linen, silk, wool, synthetic fibers, viscose fibers, etc., to effectively improve the hand feel, drape, and other properties of other fibers. Fabrics woven from green fiber yarns have a natural luster, a soft and smooth texture, a naturally comfortable hand feel, excellent drape, and good breathability, providing an exceptional wearing experience.

[0003] Currently, in the production process of green fibers, the wet opening operation is completed using a wet opening machine, and the feeding operation is completed using a feeder. That is, the wet opening and feeding operations are performed separately by two independent machines. This separate operation mode has many technical defects, seriously affecting production efficiency and product quality, specifically as follows: 1. On the one hand, the opening effect of wet opening is not good, which easily produces wet clumps of cotton and poor fiber dispersion uniformity; on the other hand, the moisture in the fiber cannot be discharged in time during the wet opening process, resulting in a high fiber moisture regain rate, which directly causes a significant increase in steam energy consumption in the subsequent drying process and increases production costs.

[0004] 2. There is a significant gap at the joint between the wet opening machine and the feeder. Combined with the vibration during equipment operation, this leads to severe cotton leakage. Additionally, the imperfect sealing structure at the roller assembly also contributes to serious cotton leakage. This leakage of fibers easily becomes contaminated, forming soiled cotton, which severely affects the quality of the final fiber product and results in fiber waste.

[0005] 3. The frames of existing wet opening equipment are mostly made of ordinary steel and simply welded together. The overall structural strength is insufficient and the stability is poor. During long-term high-speed operation, the equipment is prone to vibration and shaking, which leads to poor overall equipment operation stability and problems such as loose parts and machine shutdown, affecting the continuity of production.

[0006] 4. The sealing performance at the overlap between the cotton spreading flat curtain assembly and the cotton spreading lifting assembly is poor, and the cotton spreading lifting assembly lacks an effective negative pressure control structure on both sides, resulting in prominent cotton leakage problems. This not only causes fiber waste, but the leaked fibers also pollute the production environment and further affect fiber quality.

[0007] The aforementioned technical defects collectively result in high energy consumption, inconsistent product quality, and insufficient operational stability of existing equipment, failing to meet the demands of modern cellulose fiber production for refined, energy-efficient, and continuous production of wet opening and feeding machines. Therefore, the development of a high-performance integrated wet opening and feeding machine has become an urgent need for the current industry development. Summary of the Invention

[0008] The purpose of this invention is to provide a wet opening and feeding integrated machine to address the shortcomings of the existing technology. This invention optimizes the overall structural layout, adds a hot air recycling and dehumidification fan, and comprehensively optimizes the sealing structure to form a wet opening and feeding integrated machine. It effectively solves the technical problems of existing independent, separate equipment, such as poor fiber opening effect, serious cotton leakage, easy formation of wet cotton clumps, poor fiber dispersion uniformity, inability to timely remove moisture, high energy consumption, and insufficient stability. It has the advantages of reasonable structure, reliable operation, reduced cotton leakage, waste heat utilization, reduced moisture regain, reduced energy consumption, energy saving, good opening effect, high fiber quality, small footprint, and convenient maintenance. It can realize integrated operation of fiber opening, preheating, conveying, and cotton spreading, meeting the needs of refined, energy-saving, and continuous production in cellulose fiber production lines. It has significant practical value and broad application prospects.

[0009] The objective of this invention can be achieved through the following technical solutions: The present invention provides a wet opening and feeding integrated machine comprising a frame assembly consisting of a support frame and a sealed shell (the support frame in the frame assembly provides the installation and support foundation for other components in the present invention, and the sealed shell in the frame assembly provides the installation space for other components in the present invention). Arranged sequentially within the sealed shell cavity are a roller assembly, a cotton opening assembly, a pre-drying curtain assembly, a cotton spreading flat curtain assembly, a cotton spreading lifting assembly, and a cotton leveling device (the roller assembly smoothly feeds the fiber cotton layer into the interior of the cotton opening assembly through a clamping and conveying method; the cotton opening assembly is the core component of the fiber opening process, responsible for fully dispersing and opening the fiber cotton layer to avoid the formation of wet clumps; the pre-drying curtain assembly, as the core component of the fiber preheating process, is used to preheat the opened fibers). It also drains some moisture; the cotton spreading flat curtain assembly and the cotton spreading lifting assembly work together as the core components of fiber spreading, responsible for smoothly conveying and evenly spreading the preheated fibers to the next process; with the help of the cotton leveling device, the cotton spreading thickness can be precisely adjusted, so that the fibers can be evenly spread to the equipment of the next process. The feeding assembly is installed at the front end of the frame assembly, extends horizontally forward at the feeding end, and is closely connected to the roller assembly at the unloading end (the feeding assembly is used to stably and uniformly convey the cotton blanket-like fibers formed in the previous process to the roller assembly); at the same time, the cotton opening assembly is located directly above the front end of the pre-drying curtain plate assembly (so that the opened fibers can fall smoothly into the pre-drying curtain plate assembly), and the cotton spreading flat curtain assembly is arranged at the lower right of the unloading end of the pre-drying curtain plate assembly and the cotton spreading lifting assembly. The unloading end of the cotton-laying curtain assembly is tightly connected, and a sealing protective component is installed at the connection point (the sealing protective component can effectively reduce cotton leakage at the connection point of the front and rear conveying components); an air outlet connected to the inner cavity of the sealed shell and an air inlet connected to the dryer of the subsequent station are set directly above the pre-drying curtain assembly to realize the secondary utilization of the waste heat gas from drying (in this way, the hot air discharged from the dryer of the subsequent station is introduced into the inner cavity of the sealed shell for secondary utilization—that is, to uniformly preheat the fiber cotton layer transported on the pre-drying curtain assembly, and the secondary utilization of the waste heat gas from drying can save a lot of energy and greatly reduce energy consumption); several open-top, sloping bottom surfaces are arranged side by side in the cavity between the upper curtain plate and the return lower curtain plate of the pre-drying curtain assembly. The air outlet is a trapezoidal trough, and each air outlet is connected to a dehumidifying fan via a pipe. The hot air flowing from top to bottom preheats the fiber cotton layer transported on the pre-drying curtain assembly, and then exits through the air outlet and dehumidifying fan in sequence. At the same time, it takes away some of the moisture in the fiber, which can effectively reduce the fiber moisture regain and thus reduce the steam consumption of the subsequent drying process, thereby greatly reducing energy consumption. Above the cotton spreading curtain assembly and the cotton spreading lifting assembly, corresponding to the sealed housing, there are exhaust ducts with outlets connected to the inner cavity of the sealed housing and inlets connected to the external negative pressure fan. The exhaust ducts are used to reduce the positive pressure inside the equipment, thereby reducing cotton leakage on both sides of the cotton spreading curtain assembly and the cotton spreading lifting assembly.

[0010] The sealing and protective components described in this invention include a sealing strip and a protective cover plate (the sealing strip enables an effective seal at the connection between the front and rear conveying components and reduces cotton leakage, while the protective cover plate is used to support and fix the sealing strip).

[0011] The roller assembly described in this invention consists of an upper roller and a lower roller arranged symmetrically. The surface of the lower roller is provided with anti-slip texture (the roller assembly uses the cooperation of the upper roller and the lower roller to clamp the fiber cotton layer and feed it into the opening assembly for opening; the anti-slip texture on the surface of the lower roller can increase friction and improve the stability of clamping the fiber cotton layer).

[0012] The cotton opening assembly described in this invention has an opening roller inside, and nails are arranged on the surface of the opening roller (to make it easier to fully break up and open the cotton fiber layer).

[0013] The cotton evenness device described in this invention is positioned on the upper left of the cotton spreading and lifting assembly using a gap adjustment method, and is fixed to the frame assembly via an adjustable base plate (this allows for adjustment of the gap between the cotton evenness device and the cotton spreading and lifting assembly by adjusting the adjustable base plate, enabling precise adjustment of the cotton spreading thickness according to production needs, facilitating the even spreading of fibers to the next process equipment); nails are arranged on the surface of the cotton evenness device (this facilitates timely removal of excess cotton during the rotation of the cotton evenness device, thereby adjusting the cotton spreading thickness); the adjustable base plate consists of an outer base plate fixed to the frame assembly, an inner base plate for mounting the cotton evenness device, an adjusting screw, an adjusting screw seat fixed to the outer base plate, and a top plate fixed to the inner base plate. The inner base plate and the outer base plate are connected by bolts and long slots (this allows rotation of the adjusting screw to push the inner base plate laterally, which in turn drives the cotton evenness device to move laterally synchronously, thereby adjusting the gap between the cotton evenness device and the cotton spreading and lifting assembly).

[0014] The feeding assembly described in this invention adopts a wear-resistant and high-temperature resistant conveyor belt structure; the pre-drying curtain assembly and the cotton spreading flat curtain assembly both adopt high-temperature resistant conveyor flat curtains (because they are used to transport high-temperature fibers that are being preheated or have already been preheated); nails are arranged on the surface of the lifting curtain of the cotton spreading lifting assembly (to ensure that the cotton spreading lifting assembly can stably lift and transport the fibers at an angle upward).

[0015] The design principle of this invention is as follows: This invention, based on the actual production needs of cellulose fiber production lines, addresses the drawbacks of existing separate wet opening and feeding machines, such as cumbersome connections, severe cotton leakage, and high energy consumption. It innovatively integrates four core functions—fiber opening, preheating, conveying, and cotton spreading—into a single machine by optimizing the overall structural layout, adding hot air recycling and dehumidifying fans, and comprehensively optimizing the sealing structure. This effectively solves the technical problems of poor fiber opening effect, severe cotton leakage, easy formation of wet cotton clumps, poor fiber dispersion uniformity, inability to timely remove moisture, high energy consumption, and insufficient stability inherent in existing separate equipment. It boasts advantages such as reasonable structure, reliable operation, reduced cotton leakage, waste heat utilization, reduced moisture regain, reduced energy consumption, energy saving, good opening effect, high fiber quality, small footprint, and convenient maintenance. It enables integrated operation of fiber opening, preheating, conveying, and cotton spreading, meeting the refined, energy-saving, and continuous production needs of cellulose fiber production lines. It has significant practical value and broad application prospects.

[0016] More specifically, this invention adopts an integrated structural design, which can significantly reduce the connection links between equipment. Simultaneously, sealing and protective components are set and optimized at the connection between the cotton spreading curtain assembly and the cotton spreading lifting assembly. This fundamentally solves the technical problems of cumbersome connections and severe cotton leakage at the overlap points in traditional separate equipment. The cotton opening assembly is the core component of this invention for fiber opening. The fiber opening process is as follows: the fiber cotton layer formed in the previous process is uniformly conveyed to the roller assembly by the feeding assembly. The roller assembly holds the fiber cotton layer and smoothly feeds it into the cotton opening assembly. With the rapid rotation of the opening roller inside the cotton opening assembly, and the combined action of the nails arranged on the surface of the opening roller, the fiber cotton layer is fully dispersed, achieving uniform fiber opening and effectively avoiding the formation of wet clumps of cotton. After being opened, the fibers enter the pre-drying curtain assembly. Waste heat gas from the subsequent dryer is introduced into the sealed cavity of this invention through the air inlet duct. This waste heat gas is used to uniformly preheat the fiber layer transported on the pre-drying curtain assembly. On one hand, some of the moisture in the fibers is carried away by the hot air and discharged through the air outlet duct and dehumidifying fan, effectively reducing the fiber moisture regain and thus reducing steam consumption in subsequent drying processes, significantly lowering energy consumption. On the other hand, it also achieves secondary utilization of the waste heat gas, saving a significant amount of energy and further reducing energy consumption. The preheated fibers enter the spreading curtain assembly, which then conveys them to the spreading lifting assembly. The fiber spreading thickness is adjusted by the spreading device, while the exhaust duct continues to operate, reducing the positive pressure inside the equipment and minimizing fiber leakage. After the thickness is evenly adjusted, the fibers are conveyed by the spreading lifting assembly to the equipment corresponding to the next drying process, thus completing one wet opening and feeding operation. The entire process is continuous and stable, effectively ensuring fiber quality and reducing energy consumption. If it is necessary to adjust the production capacity or the cotton spreading thickness, the distance between the cotton spreading device and the cotton spreading lifting component can be adjusted by adjusting the adjustable base plate, and the running speed of the feeding component can be adjusted. This allows for flexible adaptation to different production needs.

[0017] The beneficial technical effects of the present invention are as follows: This invention effectively solves the technical problems of existing independent split-type equipment, such as poor fiber opening effect, serious cotton leakage, easy generation of wet cotton clumps, poor fiber dispersion uniformity, inability to remove moisture in time, high energy consumption, and insufficient stability. It has the advantages of reasonable structure, reliable operation, reduced cotton leakage, waste heat utilization, reduced moisture regain, reduced energy consumption, energy saving, good opening effect, high fiber quality, small footprint, and convenient maintenance. It can realize the integrated operation of fiber opening, preheating, conveying, and cotton laying, and meet the needs of refined, energy-saving, and continuous production of cellulose fiber production lines. It has important practical value and broad application prospects. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-5As shown, a wet opening and feeding integrated machine of the present invention includes a frame assembly 1 composed of a support frame 1-1 and a sealed shell 1-2 (the support frame 1-1 in the frame assembly 1 provides the installation and support foundation for other components in the present invention, and the sealed shell 1-2 in the frame assembly 1 provides the installation space for other components in the present invention). Roller assembly 3, cotton opening assembly 4, pre-drying curtain assembly 5, cotton spreading flat curtain assembly 6, cotton spreading lifting assembly 7, and cotton evenness device 10 are arranged sequentially in the inner cavity of the sealed shell. (The roller assembly 3 smoothly feeds the fiber cotton layer into the interior of the cotton opening assembly 4 by clamping and conveying; the cotton opening assembly 4 is the core component of fiber opening treatment, responsible for fully dispersing and opening the fiber cotton layer to avoid the formation of wet clumps; the pre-drying curtain assembly 5 is the core component of fiber preheating treatment, used to preheat the opened fibers and remove some moisture; the cotton spreading flat curtain assembly 6 and the cotton spreading lifting assembly 7 work together as the core components of fiber spreading, responsible for smoothly conveying and evenly spreading the preheated fibers to the next process;) The cotton spreading device 10, which can precisely adjust the cotton spreading thickness to facilitate the uniform spreading of fibers to the next process equipment, is installed at the front end of the frame assembly 1, with the feed end extending horizontally forward and the discharge end tightly connected to the roller assembly 3. The feed assembly 2 is used to stably and uniformly transport the cotton blanket-like fibers formed in the previous process to the roller assembly 3. At the same time, the cotton opening assembly 4 is located directly above the front end of the pre-drying curtain assembly 5 (to facilitate the smooth falling of the opened fibers onto the pre-drying curtain assembly 5), and the cotton spreading flat curtain assembly. 6 is arranged at the lower right of the unloading end of the pre-drying curtain assembly 5; the cotton spreading lifting assembly 7 is tightly connected to the unloading end of the cotton spreading flat curtain assembly 6, and a sealing protective component 14 is provided at the connection (the sealing protective component 14 can effectively reduce cotton leakage at the connection of the front and rear conveying components); an air outlet is provided directly above the pre-drying curtain assembly 5, which connects to the inner cavity of the sealing housing 1-2, and an air inlet is provided, which connects to the dryer of the subsequent station to realize the secondary utilization of the waste heat gas from drying (in this way, the hot air discharged from the dryer of the subsequent station passes through the air inlet duct 8). The waste heat gas is introduced into the inner cavity of the sealed shell 1-2 for secondary use—that is, to uniformly preheat the fiber cotton layer 12 transported on the pre-drying curtain assembly 5. The secondary use of the waste heat gas can save a lot of energy and greatly reduce energy consumption. Several air outlet ducts 9 with open tops, sloping bottoms, and trapezoidal grooves are arranged side by side in the cavity between the upper curtain 5-1 and the return lower curtain 5-2 of the pre-drying curtain assembly 5. The air outlet of each air outlet duct 9 is connected to a dehumidifying fan 13 through a pipe. After the hot air flowing from top to bottom uniformly preheats the fiber cotton layer 12 transported on the pre-drying curtain assembly 5, it is discharged through the air outlet duct 9 and the dehumidifying fan 13 in sequence. At the same time, it will take away some of the moisture in the fiber, which can effectively reduce the fiber moisture regain rate and thus reduce the steam consumption of the subsequent drying process, that is, greatly reduce energy consumption.Above the cotton-laying flat curtain assembly 6 and the cotton-laying lifting assembly 7, corresponding to the sealed housing area, are provided exhaust ducts 11. The exhaust ducts 11 connect the outlet to the inner cavity of the sealed housing and the inlet to an external negative pressure fan. (The exhaust ducts 11 are used to reduce the positive pressure inside the equipment, thereby reducing cotton leakage on both sides of the cotton-laying flat curtain assembly 6 and the cotton-laying lifting assembly 7 at the source.)

[0025] The sealing and protective component 14 described in this invention includes a sealing strip 14-1 and a protective cover plate 14-2 (the sealing strip 14-1 can form an effective seal at the connection between the front and rear conveying components and reduce cotton leakage, and the protective cover plate 14-2 is used to support and fix the sealing strip 14-1).

[0026] The roller assembly 3 described in this invention consists of an upper roller and a lower roller arranged symmetrically. The surface of the lower roller is provided with anti-slip texture (the roller assembly 3 clamps the fiber cotton layer with the cooperation of the upper roller and the lower roller and feeds it into the opening assembly 4 for opening; the anti-slip texture on the surface of the lower roller can increase friction and improve the stability of clamping the fiber cotton layer).

[0027] In this invention, the cotton opening component 4 is provided with an opening roller inside, and nails are arranged on the surface of the opening roller (to make it easier to fully break up and open the cotton fiber layer).

[0028] In this invention, the cotton evenness device 10 is positioned above the cotton spreading and lifting assembly 7 with an adjustable gap, and is fixed to the frame assembly 1 by an adjustable base plate 15 (this allows for adjustment of the gap between the cotton evenness device 10 and the cotton spreading and lifting assembly 7 by adjusting the adjustable base plate 15, enabling precise adjustment of the cotton spreading thickness according to production needs, facilitating the even spreading of fibers to the next process equipment); nails are arranged on the surface of the cotton evenness device 10 (this facilitates the timely removal of excess fibers during the rotation of the cotton evenness device 10, thereby adjusting the cotton spreading thickness); the adjustable base plate 15... The base plate 15 consists of an outer base plate 15-1 fixed to the frame assembly 1, an inner base plate 15-2 for installing the cotton spreading device, an adjusting screw 15-3, an adjusting screw seat 15-4 fixed to the outer base plate, and a top plate 15-5 fixed to the inner base plate. The inner base plate 15-2 and the outer base plate 15-1 are connected by bolts and long slots (in this way, rotating the adjusting screw 15-3 can push the inner base plate 15-2 to move laterally, and the inner base plate 15-2 will drive the cotton spreading device 10 to move laterally in sync, thereby adjusting the distance between the cotton spreading device 10 and the cotton spreading lifting assembly 7).

[0029] The feeding assembly 2 in this invention adopts a wear-resistant and high-temperature resistant conveyor belt structure; the pre-drying curtain assembly 5 and the cotton spreading flat curtain assembly 6 both adopt high-temperature resistant conveyor flat curtains (because they are used to transport high-temperature fibers that are being preheated or have already been preheated); nails are arranged on the surface of the lifting curtain of the cotton spreading lifting assembly 7 (to ensure that the cotton spreading lifting assembly 7 can stably lift and transport fibers at an angle upward).

[0030] The specific uses of this invention are as follows: This invention is applicable to cellulose fiber production lines, primarily installed between the refining and drying processes. It serves as a connecting device between the two, undertaking the integrated tasks of fiber opening, preheating, conveying, and cotton spreading. Before using this invention, operators need to perform the following preparations: First, thoroughly check the condition of all components—ensuring the frame assembly 1 is securely fixed without looseness, the sealing and protective components 14 are structurally intact and undamaged, the air inlet duct 8, air outlet duct 9, dehumidifying fan 13, and exhaust duct 11 are all unobstructed, and the cotton spreading device 10 is flexible and unimpeded. Next, based on the capacity requirements and fiber quality requirements of the subsequent drying process, adjust the distance between the cotton spreading device 10 and the cotton spreading lifting assembly 7 using the adjustable base plate 15—this allows for precise adjustment of the cotton spreading thickness according to production needs, facilitating the even spreading of fibers to the next process equipment. Simultaneously, set the pre-drying hot air temperature, conveying speed, and dehumidifying fan speed to ensure the fiber moisture regain is controlled within a reasonable range, guaranteeing the smooth operation of the subsequent drying process.

[0031] After the equipment of this invention is officially started, the fiber cotton layer 12 formed in the previous process is uniformly conveyed to the roller assembly 3 by the feeding assembly 2; the roller assembly 3 holds the fiber cotton layer 12 and smoothly feeds it into the opening assembly 4 for full opening, fully dispersing and opening to avoid the formation of wet clumps of cotton; the opened fibers enter the pre-drying curtain assembly 5, and hot air discharged from the dryer of the subsequent station is introduced through the air inlet duct 8. The recycled hot air is used to preheat the fibers, and some of the moisture in the fibers is carried away by the hot air and discharged through the air outlet duct 9 and the dehumidification fan 13, thus effectively... The fiber moisture regain rate is reduced, thereby reducing steam consumption in subsequent drying processes. Preheated fibers enter the cotton spreading curtain assembly 6, which then conveys them to the cotton spreading lifting assembly 7. The cotton spreading thickness is adjusted by the cotton leveling device 10. The exhaust duct 11 operates continuously to reduce internal positive pressure and minimize fiber leakage. After uniform thickness adjustment, the fibers are conveyed by the cotton spreading lifting assembly 7 to the equipment corresponding to the next drying process, thus completing one full wet opening and feeding operation. The entire process is continuous and stable, effectively ensuring fiber quality and reducing energy consumption. During use, operators must regularly check the equipment's operating status, promptly clean fiber residue from the cotton opening assembly 4, check the wear of the sealing protective parts 14 and replace them as needed to ensure continuous and stable equipment operation. When the equipment is shut down, all fans and hot air inputs must be turned off—that is, the air inlet duct 8 connected to the hot air discharged from the dryer in the subsequent workstation must be closed immediately. After the equipment cools down, clean the residual fibers inside the equipment, perform equipment cleaning and maintenance, and regularly add lubricating oil to all rotating parts to extend the equipment's service life and ensure long-term stable operation.

[0032] When it is necessary to adjust the production capacity or the cotton spreading thickness, the distance between the cotton spreading device 10 and the cotton spreading lifting component 7 can be adjusted by adjusting the adjustable base plate 15, and the running speed of the feeding component 2 can be adjusted, so as to flexibly adapt to different production needs.
