Abstract
Description
Technical Field
[0001] This utility model relates to a spinning system, specifically a multifunctional spinning system, which enables diversified production of yarn products (non-cotton pure spinning and blended spinning). At the same time, it can realize the incubation of new yarn products for small-scale, pilot-scale and large-scale application, meeting actual needs, and belongs to the field of spinning technology. Background Technology
[0002] Yarn is a textile product made from various textile fibers processed to a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery, and is mainly divided into staple fiber and filament. The yarn production process mainly includes: cotton blending, opening, carding, drawing, spinning, and post-processing (winding, doubling, twisting, etc.).
[0003] When researching differentiated new yarn products (considering factors such as raw materials, processes, and equipment), small-scale spinning production lines can be used to achieve rapid spinning modifications, produce the required samples, and quickly observe the trial spinning performance of the raw materials used, resulting in low consumption. Furthermore, rapid spinning with small yarns allows for direct comparison of dyeing differences between different raw materials, facilitating the development of formulation plans for large-scale spinning. In addition, the spinnability of yarns spun from different raw material combinations can be tested using a single-machine experiment method.
[0004] However, for some large factories, when special samples and small batches are required, large production machines are generally used. This results in problems such as occupying many spindles, numerous influencing factors, difficulty in control, high losses, high energy consumption, long processing time, and a large workload for re-spinning. In addition, insufficient supply of fiber raw materials leads to waste, frequent changes in fiber raw material production lines, and significant differences in fiber between production lines and between batches. When comparing the dyeing performance of short fibers between batches, it is impossible to visually determine the differences between batches by simply dyeing short fibers; only after the fibers are spun into yarn and woven into fabric can the visible effects be seen.
[0005] Therefore, a multi-functional spinning production line is needed to meet the needs of yarn sampling, new product development, and fiber weaving and dyeing performance testing. Summary of the Invention
[0006] To address the problems of existing technologies, a multifunctional spinning system is proposed. In this technical solution, through specific combinations and arrangements of various devices, the spinning system is ensured to be suitable not only for different types and proportions of fiber raw materials (such as lyocell, viscose, polyester, etc.; pure spinning and blended spinning), but also for different spinning methods (such as vortex spinning and compact spinning). This allows for diversified spinning based on actual needs, such as sample making, and enabling research on the spinnability and downstream performance of samples under various conditions.
[0007] To achieve the above technical objectives, the following technical solution is proposed:
[0008] The purpose of this technical solution is to provide: a multi-functional spinning system, including a cotton grabber, a cotton blender, a fine cotton opener, a carding machine, a first drawing frame and a second drawing frame arranged in sequence, a third drawing frame is provided behind the station of the second drawing frame, and a vortex spinning machine is provided behind the station of the third drawing frame. A continuous vortex spinning path is formed between the cotton grabber, cotton blender, fine cotton opener, carding machine, first drawing frame, second drawing frame, third drawing frame and vortex spinning machine.
[0009] The second drawing frame is also equipped with a roving frame behind the station, a spinning frame behind the station of the roving frame, and a winding machine behind the station of the spinning frame. The cotton grabber, cotton blender, cotton opener, carding machine, first drawing frame, second drawing frame, roving frame, spinning frame and winding machine form a continuous path for compact spinning.
[0010] Cotton grabbers: There are two units, including disc cotton grabber I and disc cotton grabber II. Disc cotton grabber I and disc cotton grabber II are connected by an automatic distributor I. Cotton grabber II is connected to the condenser through the automatic distributor II. The condenser is connected to the fiber separator and compactor in the dust removal chamber through the return air duct I. The condenser is connected to a condensing fan, and a baling machine is located below the condenser. The automatic distributor I is connected to the blending machine through the conveying pipe I. The configuration of two disc cotton grabbers better adapts to this diversified spinning production line. For example, it allows for better batching of different proportions and types of fiber raw materials. It features small footprint, high flexibility, strong mobility, convenient cotton blending, and suitability for small-scale production.
[0011] A heavy object separator is installed between the conveying pipe I and the cotton blending machine. The inlet of the heavy object separator is connected to a separating fan. The outlet of the heavy object separator is connected to the fiber separating and pressing device in the dust removal chamber through the return air pipe II. The outlet of the heavy object separator is connected to the inlet of the cotton blending machine. A cotton blending fan (e.g., an axial flow fan) is installed at the inlet of the cotton blending machine.
[0012] Cotton blending machine: It is a multi-compartment cotton blending machine. The discharge port of the cotton blending machine is connected to the fine cotton opening machine through conveying pipe II. The conveying pipe II is equipped with an iron remover.
[0013] Fine opening machine: The fine opening machine is equipped with a fine opening fan at the feed inlet. The fine opening machine is connected to the carding machine through conveyor pipe III. The carding fan (e.g., axial flow fan) is installed on conveyor pipe III.
[0014] Carding machine: at least two, the carding machines are set in parallel. The air outlet of the carding machine is connected to the fiber separator and press in the dust removal chamber through return air pipe III. The carding machine outlet is equipped with a sliver barrel. The first drawing frame is located behind the station of the sliver barrel, and the second drawing frame is located behind the station of the first drawing frame.
[0015] Furthermore, the heavy object separator includes a housing and a rotating drum housed within the housing. The rotating drum rotates, and its inner cavity is connected to the return air pipe II. A stripping roller is located on one side of the rotating drum, positioned in front of the outlet of the heavy object separator. Under the action of the separating fan, material from the cotton grabber is fed into the housing through the conveying pipe I. Under the negative pressure of the return air pipe II, the fibrous material (lighter weight) adheres to the surface of the rotating drum, while the heavy impurities fall below the rotating drum, thus achieving the separation of fibrous material from heavy impurities. When the fibrous material on the rotating drum rotates the stripping roller, the stripping roller peels off the fibrous material attached to the rotating drum, and under the action of the blending fan, the material after the heavy impurities are removed is conveyed to the blending machine.
[0016] Furthermore, the multi-compartment blending machine is a serpentine feeding multi-compartment blending machine, which can buffer the fiber material in the feeding mechanism at the top of the blending machine box, so that the fiber material is evenly fed into multiple blending compartments and achieves uniform feeding.
[0017] Furthermore, the multi-compartment cotton blending machine includes a cotton blending input pipe connected to the discharge port of the heavy object separator, a material discharge mechanism, multiple cotton blending compartments, a cotton feeding roller, a cotton equalization roller, a conveyor belt, and a cotton blending output pipe connected to the conveying pipe II. The material discharge mechanism includes a discharge pipe and an S-shaped material discharge channel. One end of the discharge pipe is connected to the cotton blending fan, and the other end is connected to the material discharge channel. The material discharge channel is connected to each cotton blending compartment.
[0018] There are multiple cotton feeding rollers, distributed below the cotton mixing bin, and the conveyor belt is located below the cotton feeding rollers;
[0019] There are multiple cotton blending rollers, distributed at the discharge port of the cotton blending machine;
[0020] When the conveyor belt is working, it passes under multiple cotton mixing bins in sequence. When the fiber material output from each bin falls onto the conveyor belt, the fiber material falling from the previous bin is transferred to the bottom of the next bin, and so on. The fiber material in each bin is further mixed on the conveyor belt, thereby improving the uniformity of the mixing.
[0021] Furthermore, the magnetic separator is a bridge-type magnetic separator, which is detachably installed on the conveying pipe II. Preferably, the bridge-type magnetic separator is fixed to the conveying pipe II via a connecting flange, facilitating its disassembly and installation, saving time and effort; and a sealing ring is provided between the bridge-type magnetic separator and the conveying pipe II to increase the sealing performance of the conveying pipe II, thereby improving the stability and continuity of material conveying.
[0022] Furthermore, the bridge-type magnetic iron remover includes an inverted V-shaped drainage cavity and a powerful permanent magnet block disposed within the drainage cavity. A movable cleaning door is also fitted onto the drainage cavity, and the movable cleaning door is equipped with a handle to facilitate timely cleaning of metal shavings and impurities on the powerful permanent magnet block.
[0023] Furthermore, there are two powerful permanent magnet blocks, one distributed on the lower side of the feeding section of the drainage cavity and the other distributed on the upper side of the discharging section of the drainage cavity. This arrangement follows the direction of the material, thereby improving the efficiency and quality of removing metal shavings and impurities, and providing an effective prerequisite for subsequent diversified spinning.
[0024] Furthermore, the carding machine is equipped with a detachable cotton feeding hopper.
[0025] In this technical solution, the positional relationships involved, such as "rear side of workstation", "front side of workstation", "between", "upper", "lower", "one side", "one end", "the other end", "previous workstation", and "next workstation", are defined according to the actual usage conditions and are conventional terms in this technical field, as well as conventional terms used by those skilled in the art in actual use.
[0026] In the description of this technical solution, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technical solution based on the specific circumstances.
[0027] The beneficial technical effects of adopting this technical solution are as follows:
[0028] I. This utility model provides a multifunctional spinning system that is well integrated with diversified spinning processes, enabling small-batch, differentiated yarn production, and effectively improving the flexibility, timeliness, and accuracy of experimental data in small-batch production conversion, thus possessing good practicality.
[0029] Second, in this utility model, through specific combinations and arrangements of various equipment, it is applicable to different spinning methods and facilitates respinning modifications. For example, a continuous vortex spinning path is formed between the cotton grabber, cotton blender, cotton opener, carding machine, first drawing frame, second drawing frame, third drawing frame, and vortex spinning machine; or a continuous compact spinning path is formed between the cotton grabber, cotton blender, cotton opener, carding machine, first drawing frame, second drawing frame, roving frame, spinning frame, and winding machine. The cotton grabber, cotton blender, cotton opener, carding machine, first drawing frame, and second drawing frame form a common production line segment used for different spinning methods. This arrangement can effectively reduce the number of equipment, lower costs, and improve the operational flexibility of the production line.
[0030] By specifically configuring the disc cotton grabber I, disc cotton grabber II, and multi-compartment cotton blender, the fiber raw materials are ensured to be mixed evenly, and then spun into fibers. This ensures that the production line is suitable for different types of raw materials and different proportions of raw materials.
[0031] By specifically arranging each fan, the stable, orderly, and effective transportation of fiber raw materials is ensured during processes such as cotton grabbing, blending, opening, and carding, thus ensuring effective connection between each process.
[0032] By incorporating heavy object separators, bridge-type magnetic iron removers, and impurity removal boxes, timely impurity removal is ensured, facilitating subsequent spinning processes and improving yarn product quality. This is particularly beneficial for Lyocell fibers, which have strict requirements for raw material specifications. Attached Figure Description

[0060] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0061] Example 1
[0062] A multifunctional spinning production system, such as Figure 1-2 As shown in Figure 5, the machine includes a cotton grabber 1, a multi-compartment cotton blender 2, a fine cotton opener 3, a carding machine 4, a first-stage drawing frame 5, and a second-stage drawing frame 6 arranged in sequence.
[0063] The cotton grabber 1 includes a disc cotton grabber I 101 and a disc cotton grabber II 102. The disc cotton grabber I 101 and the disc cotton grabber II 102 are connected by an automatic distributor I 103, which is connected to a multi-compartment cotton blender 2. The disc cotton grabber II 102 is connected to a cotton condenser 9 via an automatic distributor II 104. A baler 10 is located below the cotton condenser 9, in front of the station of the disc cotton grabber I 101 and below the disc cotton grabber II 102. The following structures are arranged: 1. Behind or in front of station 2; 2. A continuous path for single-fiber raw material grabbing, mixing, and conveying is formed between disc cotton grabber I 101 and / or disc cotton grabber II 102, automatic distributor I 103, and multi-compartment blender 2; 3. A continuous path for two or more fiber raw material batching, grabbing, mixing, and conveying is formed between disc cotton grabber I 101, disc cotton grabber II 102, automatic distributor I 103, automatic distributor II 104, cotton condenser 9, baler 10, and multi-compartment blender 2. The arrangement of two disc cotton grabbers 1 better adapts to this multi-functional spinning production line, allowing for better batching of different proportions and types of fiber raw materials. It features small footprint, high flexibility, strong mobility, convenient cotton batching, and suitability for small-scale production.
[0064] Behind the station of the second drawing frame 6 is a third drawing frame 14, and behind the station of the third drawing frame 14 is a vortex spinning machine 15. A continuous vortex spinning path is formed between the cotton grabber 1, the multi-compartment blender 2, the fine cotton opener 3, the carding machine 4, the first drawing frame 5, the second drawing frame 6, the third drawing frame 14, and the vortex spinning machine 15 (e.g., Figure 3 (as shown)
[0065] Behind the station of the second drawing frame 6, there is a roving frame 16, behind the station of the roving frame 16, there is a spinning frame 17, and behind the station of the spinning frame 17, there is a winding machine 18.

[0066] In one implementation, in the arrangement of the first drawing frame 5, the second drawing frame 6, the roving frame, the spinning frame 17, and the winding machine 18, each piece of equipment is set up independently, and the yarn / sliver corresponding to the previous process is respectively transported by yarn carriages (e.g., Figure 10 As shown, the strips and drums are transported to the next process, which realizes the "connection" between the independent equipment. That is, the connection here is a connection in a broad sense.
[0067] Example 2
[0068] Based on Example 1, this example further specifies the following to ensure the stability and controllability of material conveying:
[0069] Automatic channel divider I103 is connected to multi-compartment cotton blender 2 through conveying pipe I7. A heavy object separator 8 is provided between conveying pipe I7 and multi-compartment cotton blender 2. The outlet of heavy object separator 8 is connected to the inlet of multi-compartment cotton blender 2.
[0070] The discharge port of the multi-compartment cotton blender 2 is connected to the fine cotton opener 3 through the conveying pipe II11;
[0071] The fine opening machine 3 is connected to the carding machine 4 through the conveying pipe Ⅲ 12.
[0072] Example 3
[0073] Based on Examples 1-2, this example further specifies the arrangement between the carding machine 4, the first drawing frame 5, and the second drawing frame 6:
[0074] There are at least two carding machines 4, which are connected in parallel. A sliver barrel 13 is provided at the outlet of the carding machine 4. The first drawing frame 5 is located behind the station of the sliver barrel 13, and the second drawing frame 6 is located behind the station of the first drawing frame 5.
[0075] The carding machine 4 is equipped with a detachable cotton feeding hopper 401.
[0076] Example 4
[0077] Based on Examples 1-3, this example further specifies the following to ensure the stability and controllability of material conveying:
[0078] The cotton condenser 9 is connected to a cotton condensing fan 19, the inlet of the heavy object separator 8 is equipped with a separation fan 20, the inlet of the multi-compartment cotton blender 2 is equipped with a cotton blending fan 21, the inlet of the fine cotton opener 3 is equipped with a fine cotton opener fan 22, and the inlet of the carding machine 4 is equipped with a carding fan 23.
[0079] In addition, the air outlet of the condenser 9 is connected to the dust removal chamber 27 via return air duct I 24, the air outlet of the heavy object separator 8 is connected to the dust removal chamber 27 via return air duct II 25, and the air outlet of the carding machine 4 is connected to the dust removal chamber 27 via return air duct III 26; the dust removal chamber 27 is equipped with a fiber separating and pressing device 28 (such as... Figure 11 As shown in the figure, on the one hand, it ensures the effective transportation of fiber materials, and on the other hand, it ensures the cleanliness and stability of the working environment.
[0080] Example 5
[0081] Based on embodiments 1-4, this embodiment further defines the heavy object separator 8 to further illustrate the technical solution.
[0082] like Figure 6 As shown, the heavy object separator 8 includes a housing 801 and a rotating drum 802 disposed inside the housing 801. The rotating drum 802 rotates, and its inner cavity 804 is connected to the return air pipe II 25. A cotton stripping roller 803 is provided on one side of the rotating drum 802, located in front of the outlet of the heavy object separator 8. Under the action of the separating fan 20, the material from the cotton grabber 1 is sent into the housing 801 through the conveying pipe I 7. Then, under the negative pressure of the return air pipe II 25, the fibrous material (lighter weight) adheres to the surface of the rotating drum 802, while the heavy impurities fall below the rotating drum 802, thereby achieving the separation of fibrous material and heavy impurities. When the fibrous material on the rotating drum 802 rotates the cotton stripping roller 803, the cotton stripping roller 803 peels off the fibrous material attached to the rotating drum 802, and under the action of the blending fan 21, the material after the heavy impurities are discharged is conveyed to the blending machine.
[0083] Example 6
[0084] Based on Examples 1-5, this example further defines the multi-compartment cotton blending machine 2 to further illustrate the technical solution.
[0085] The multi-compartment cotton blender 2 is a serpentine feeding multi-compartment cotton blender 2, which can buffer the fiber material in the feeding mechanism at the top of the blender box, and evenly drop the fiber material into multiple blending compartments 203, achieving uniform feeding.
[0086] like Figure 7-8 As shown, the multi-compartment cotton blending machine 2 includes a cotton blending input pipe 201 connected to the discharge port of the heavy object separator 8, a material discharge mechanism, multiple cotton blending compartments 203, a cotton feeding roller 204, a cotton leveling roller 205, a conveyor belt 206, and a cotton blending output pipe 207 connected to the conveying pipe 11. The material discharge mechanism includes a discharge pipe 202 and an S-shaped material discharge channel 208. One end of the discharge pipe 202 is connected to the cotton blending fan 21, and the other end is connected to the material discharge channel 208. The material discharge channel 208 is connected to each cotton blending compartment 203. There are multiple cotton feeding rollers 204, which are distributed below the cotton blending compartments 203. The conveyor belt 206 is located below the cotton feeding rollers 204. There are multiple cotton leveling rollers 205, which are distributed at the discharge port of the cotton blending machine.
[0087] When the conveyor belt 206 is working, it passes under multiple cotton mixing bins 203 in sequence. When the fiber material output from each bin falls onto the conveyor belt 206 for conveying, the fiber material falling from the previous bin is conveyed to the bottom of the next bin, and so on. The fiber material in each bin is further mixed on the conveyor belt 206, thereby improving the uniformity of the mixing.
[0088] The cotton blending machine is a crucial piece of equipment in the carding and combing process, primarily responsible for blending and storing cotton. The multi-compartment blending machine 2 can uniformly mix raw materials, ensuring equal component content per unit mass of different raw materials. This eliminates problems such as yarn color difference and strength unevenness caused by uneven raw material mixing in subsequent processes. Furthermore, its large cotton storage capacity is a prerequisite for continuous and stable production in the carding and combing process. However, existing multi-compartment blending machines 2 often suffer from unstable pressure detection. If a malfunction occurs during use, it can affect the output of the entire carding and combing production line, and even lead to shutdown. Therefore, a pressure sensor I42 is installed on the blending input pipe 201, and the pressure sensor I42 is interlocked with the blending fan 21 via an electrical signal.
[0089] Example 7
[0090] Based on Examples 1-6, this example further specifies the following to ensure the stability and purity of material conveying:
[0091] A bridge-type magnetic iron remover 29 (such as) is fitted onto the conveying pipe II11. Figure 9 As shown, the bridge-type magnetic separator 29 is detachably installed on the conveying pipe II11, which facilitates the disassembly and installation of the bridge-type magnetic separator 29, saving time and effort; and a sealing ring is provided between the bridge-type magnetic separator 29 and the conveying pipe II11 to increase the sealing performance of the conveying pipe II11, thereby improving the stability and continuity of material conveying.
[0092] The bridge-type magnetic iron remover 29 includes an inverted V-shaped drainage cavity 290 and a powerful permanent magnet block 291 disposed in the drainage cavity 290. A movable cleaning door 292 is also fitted on the drainage cavity 290. The movable cleaning door 292 is equipped with a handle 293 to facilitate timely cleaning of metal shavings and impurities on the powerful permanent magnet block 291.
[0093] There are two powerful permanent magnet blocks 291, one distributed on the lower side of the feeding section of the diversion cavity 290 and the other distributed on the upper side of the discharging section of the diversion cavity 290. This arrangement follows the direction of the material, thereby improving the efficiency and quality of removing metal shavings and impurities, and providing an effective prerequisite for subsequent diversified spinning.
[0094] Example 8
[0095] Based on Examples 1-7, this example provides: a multifunctional spinning production process, such as... Figure 16 , 18 As shown, it includes cotton grabbing process, cotton blending process, fine cotton opening process, cotton carding process, first drawing process and second drawing process;
[0096] S1 Cotton Grabbing Process: The fiber raw material bales are fed into the disc cotton grabber I or / and disc cotton grabber II, and the bales are arranged, cotton is grabbed and mixed according to the type and ratio of the raw materials.
[0097] S2 Cotton Blending Process: The fiber material processed in step S1 is fed into a multi-compartment cotton blender for further blending;
[0098] S3 Fine opening process: The fiber material processed in step S2 is fed into the fine opening machine for loosening;
[0099] S4 Carding process: The fiber material processed in step S3 is fed into the carding machine, the carding control parameters (such as sliver output speed) are adjusted, the carding is opened and separated to obtain sliver;
[0100] S5 First drawing process: The sliver processed in step S4 is fed into the first drawing frame. The first drawing control parameters (such as first drawing draft ratio, first drawing speed and first drawing quantity) are adjusted to perform the first drawing process and obtain the first drawing sliver.
[0101] S6 Second drawing process: The first drawing sliver processed in step S5 is fed into the second drawing frame. The control parameters of the second drawing sliver (such as the second drawing draft ratio, the second drawing speed and the second drawing quantity) are adjusted to perform the second drawing process and obtain the second drawing sliver.
[0102] When using vortex spinning, the two-draw sliver processed in step S6 is fed into a three-draw frame for three-draw sliver production. Then, the three-draw sliver is fed into a vortex spinning machine, and the vortex spinning control parameters (such as spinning speed, spinning tension, total draft ratio, main draft ratio, back draft ratio, back roller initiation rate, electro-cleaning parameters, and tail yarn winding time) are adjusted to produce vortex-spun yarn.
[0103] When using the compact spinning method, the two slivers processed in step S6 are fed into the roving frame. The spinning control parameters in the roving frame (such as draft ratio, twist, full yarn length, spindle speed, and roving tension) are adjusted to spin roving, resulting in roving. Then, the roving is fed into the spinning frame, and the spinning control parameters in the spinning frame (such as draft ratio, twist, full yarn length, and spindle speed) are adjusted to spin fine yarn. The fine yarn is fed into the winding machine, and the winding control parameters (such as electro-cleaning parameters, spinning speed, full bobbin length, and bobbin tension) are adjusted to wind fine yarn, resulting in compact spun yarn.
[0104] Specifically, depending on the downstream product specification requirements, corresponding spinning methods and production lines can be adopted, and corresponding control parameters can be adjusted to ultimately produce different yarn products. For example, controlling various key parameters (selecting specific control points) can better adapt to different spinning methods. For instance, in eddy current spinning, the electro-cleaning parameters are used for splicing monitoring to detect indicators such as the proportion of neps, the proportion of coarse neps, and the length of coarse neps in the yarn splice.
[0105] In compact spinning, the gripping force in the roving frame is used to control the stability of roving draft, which is adjusted by spacers; the draft ratio determines the roving linear density, the twist determines the degree of twisting, the full length determines the yarn capacity on the roving bobbin, and the spindle speed determines the roving spinning speed. These factors are also coordinated with subsequent spinning control parameters.
[0106] In a spinning frame, the rear drive draft ratio affects draft distribution and is adjusted via the rear drive draft gear. The total draft ratio determines the yarn linear density, twist determines the degree of twisting, full yarn length determines the yarn capacity on the bobbin, and spindle speed determines the spinning speed. The gripping force controls the stability of the yarn draft and is adjusted via spacers. The traveler weight controls the size of the air ring. These factors are also considered in conjunction with subsequent winding control parameters.
[0107] In a winding machine, the settings of the electronic cleaning parameters can be adjusted according to product quality to detect yarn defects and evenness; the full length of the bobbin determines the length of different types and models of yarn, etc.
[0108] In addition, before the cotton blending process in step S2, a heavy object separator is used to separate heavy impurities. This improves the purity of the fiber material, thus improving the quality of the subsequent yarn, and also ensures the sustainability and continuity of the subsequent processes.
[0109] Based on this spinning system, different mixing methods are adopted for different proportions and types of raw materials, as follows:
[0110] 1. In the cotton grabbing process, if the fiber raw material is of one type, the fiber raw material package is placed in disc cotton grabber I and / or disc cotton grabber II for grabbing and mixing, and then conveyed to the multi-compartment cotton blender through conveyor pipe I. Figure 12 As shown;
[0111] II. If there are two or more fiber raw materials with equal mass ratios: The fiber raw material bales are placed in the disc cotton grabber II and arranged in a sequential order with adjacent intervals. After grabbing and mixing, they are sequentially conveyed to the condenser and baler to obtain fiber bales I. Then, the processed fiber bales I are sent to the disc cotton grabber I for secondary grabbing and mixing, and then conveyed to the multi-compartment blender via conveyor pipe I. For example: If there are two fiber raw materials (in a 1:1 ratio), denoted as A and B, fiber raw material bales A and B are placed in the disc cotton grabber II or disc cotton grabber I and arranged in a sequential order with adjacent intervals (e.g., AB, AB). After grabbing and mixing, they are conveyed to the multi-compartment blender via conveyor pipe I. Figure 13 As shown;
[0112] Alternatively, two fiber raw materials (in a 1:1 ratio) are used, labeled A and B respectively. The fiber raw material packages A and B are fed into the disc cotton grabber II and arranged in a sequential order with adjacent intervals (e.g., AB, AB). After grabbing and mixing, they are conveyed to the cotton condenser and the baler in sequence. Then, the processed AB fiber raw material package is sent to the disc cotton grabber I for secondary grabbing and secondary mixing, and then conveyed to the multi-compartment cotton blender through the conveyor pipe I.
[0113] For example: If there are three types of fiber raw materials (in a ratio of 1:1:1), labeled as C, D and E respectively, the fiber raw material packages of C, D and E are put into the disc cotton grabber II and arranged in a sequential order of adjacent intervals (e.g., CDE, CDE) for cotton grabbing and mixing. After that, they are conveyed to the multi-compartment cotton blender through the conveyor pipe I.
[0114] Alternatively, the treated fiber bale I can be returned to the disc cotton grabber II, while another fiber raw material bale is simultaneously added and arranged in a regular, alternating sequence for secondary cotton grabbing and mixing. After this secondary process, the fibers are then conveyed sequentially to the condenser and baler. Then, the treated fiber bale II is returned to the disc cotton grabber I for a third round of grabbing and mixing before being conveyed to the multi-compartment blender via conveyor pipe I. For example: fiber raw material bales C and D are placed in the disc cotton grabber II and arranged in a regular, alternating sequence (e.g., CD, CD) for grabbing and mixing, then conveyed sequentially to the condenser and baler. Then, the treated CD fiber raw material bale is returned to the disc cotton grabber I, while another fiber raw material bale E is simultaneously added and arranged in a regular, alternating sequence (e.g., CD.E, CD.E) for secondary grabbing and mixing before being conveyed to the multi-compartment blender via conveyor pipe I. Figure 14 As shown;
[0115] 3. If there are two or more fiber raw materials and they are not in equal mass ratio: put the fiber raw material package into the disc cotton grabber II and arrange them in a regular order with adjacent intervals. After grabbing and mixing, it is conveyed to the cotton condenser and the baler in sequence to obtain fiber package III. Then, send the processed fiber package III to the disc cotton grabber I for secondary grabbing and secondary mixing, and then convey it to the multi-compartment cotton blender through the conveying pipe I. For example: If there are three types of fiber raw materials (in a ratio of 2:3:3), denoted as F, G, and H respectively, the fiber raw material packages F, G, and H are placed in a disc cotton grabber II, arranged in an adjacent interval pattern (e.g., FGH, FGH) for grabbing and mixing, and then sequentially conveyed to the condenser and baler. Then, the processed FGH fiber raw material package is sent to a disc cotton grabber I, while the larger fiber raw material packages G and H are simultaneously placed in an adjacent interval pattern (e.g., FGH.FGH.GH, FGH.FGH.GH) for secondary grabbing and mixing, and then conveyed through conveyor pipe I to a multi-compartment blender. Figure 15 As shown;
[0116] For example: There are two types of fiber raw materials (in a ratio of 2:1), denoted as I and J respectively. The fiber raw material packages I and J are fed into the disc cotton grabber II and arranged in a regular sequence with adjacent intervals (e.g., IJ, IJ). After grabbing and mixing, they are conveyed to the cotton condenser and the baler in sequence. Then, the processed fiber raw material package IJ is sent to the disc cotton grabber I. At the same time, fiber raw material package I, which accounts for a larger mass ratio, is fed into the disc cotton grabber I and arranged in a regular sequence with adjacent intervals (e.g., IJ.I, IJ.I). After secondary grabbing and secondary mixing, it is conveyed to the multi-compartment cotton blender through the conveyor pipe I.
[0117] Alternatively, the treated fiber bale III can be sent back to the disc cotton grabber II, while fiber raw material bales with a larger mass ratio are added and arranged in a regular sequence with adjacent intervals. After secondary cotton grabbing and secondary mixing, they are conveyed to the cotton condenser and baler in sequence. Then, the treated fiber bale IV can be sent to the disc cotton grabber I, where it undergoes tertiary cotton grabbing and tertiary mixing before being conveyed to the multi-compartment cotton blender via the conveyor pipe I. For example: There are two types of fiber raw materials (in a 3:1 ratio), denoted as M and N respectively. The fiber raw material packages M and N are fed into the disc cotton grabber II and arranged in a sequential order with adjacent intervals (e.g., MN, MN). After grabbing and mixing, they are sequentially conveyed to the condenser and the baler. The processed HI fiber raw material package is then sent back to the disc cotton grabber II, and simultaneously, the fiber raw material package M, which has a larger mass ratio, is added and arranged in a sequential order with adjacent intervals (e.g., MN.M, MN.M). After a second grabbing and mixing, it is sequentially conveyed to the condenser and the baler. Then, the processed fiber raw material package MN.M is sent to the disc cotton grabber I, and simultaneously, the fiber raw material package M, which has a larger mass ratio, is added and arranged in a sequential order with adjacent intervals (e.g., MNM.M, MNM.M). After a third grabbing and mixing, it is conveyed through conveyor pipe I to the multi-compartment blender.
