Description

Technical Field

[0001] This invention relates to the field of cashmere garment processing, specifically to a fabric combing device and its process in cashmere garment processing. Background Technology

[0002] Current cashmere carding processes often employ fixed carding teeth or card cloths on the cylinder surface for continuous, uniform-intensity rigid carding. This type of structure maintains a relatively constant carding force on the fiber layer during operation, lacking rhythmic variation and flexible adjustment capabilities. This easily leads to fibers being held tightly in localized areas for extended periods, resulting in fiber breakage, increased short fibers, or insufficient fiber bundle dispersion. Furthermore, due to the relatively uniform distribution of carding force, fibers tend to adhere or accumulate on the cylinder surface, causing uneven fiber flow and consequently leading to evenness fluctuations and insufficient carding stability.

[0003] Therefore, a fabric combing device and its process are provided to address the above-mentioned problems in the cashmere garment processing. Summary of the Invention

[0004] This invention addresses the problems of lack of flexible adjustment of combing force, easy fiber breakage, increased short fiber content, uneven fiber layer flow, and evenness fluctuation caused by the use of fixed combing teeth for continuous and rigid combing in existing cashmere combing processes. It provides a fabric combing device and process for cashmere garment processing.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0006] The present invention provides a fabric combing device for cashmere garment processing, including a frame, on which a self-rotating cylindrical main cylinder is installed, and a self-rotating cylindrical auxiliary cylinder is arranged on one side of the main cylinder. Multiple evenly distributed main combing parts and auxiliary combing parts are fixed on the annular surfaces of the main cylinder and the auxiliary cylinder, and adjacent main combing parts and auxiliary combing parts are meshed with each other.

[0007] An adjustment component is installed inside the auxiliary cylinder. When the auxiliary cylinder rotates, the adjustment component causes the adjustment combing component located on the surface of the auxiliary cylinder to extend and retract. The adjustment combing component is located in the gap between the main combing component and the auxiliary combing component.

[0008] By incorporating retractable and adjustable combing elements on the adjustment assembly, these elements can periodically extend and retract during the rotation of the auxiliary cylinder. This applies a rhythmically varying, flexible combing action to the fiber layer located in the combing zone between the main and auxiliary cylinders. Compared to methods that rely solely on fixed combing elements for continuous gripping, this structure creates a dynamically changing distribution of combing force during the rotation of the auxiliary cylinder. This allows the fibers to be sequentially gripped, disturbed, and released within different time windows, which helps to gradually break up the fiber bundles and improve the parallel alignment of the fibers, thereby enhancing the completeness of combing.

[0009] In this technical solution, both sides of the main cylinder are mounted on the frame, and a first transmission pulley is fixed on the circular end face of one side of the main cylinder. The first transmission pulley is connected to the corresponding drive motor, and the drive motor drives the main cylinder to rotate.

[0010] Both sides of the auxiliary cylinder are mounted on the frame. A second transmission pulley is fixed on one end of the auxiliary cylinder. The second transmission pulley is connected to the corresponding drive motor, which drives the auxiliary cylinder to rotate.

[0011] The main cylinder and auxiliary cylinder are driven to rotate by the transmission connection between the first and second transmission pulleys and the corresponding motors.

[0012] In this technical solution, the auxiliary cylinder is a hollow cylindrical shell structure, and a connecting pipe is fixed on both circular end faces of the auxiliary cylinder. The connecting pipe is connected to the inner cavity of the auxiliary cylinder, and the second transmission pulley is sleeved and fixed on the corresponding connecting pipe.

[0013] The bearing shaft is inserted into the inner cavity of the auxiliary cylinder. The auxiliary cylinder can rotate on the bearing shaft, and its two ends protrude from the corresponding ends of the connecting tube. The two ends of the bearing shaft are fixed to the frame by the connecting bracket. The bearing shaft and the auxiliary cylinder are coaxially arranged.

[0014] In this technical solution, the adjustment component includes a driving part and a driven part. The driving part is disposed on the bearing shaft, and there are multiple driven parts arranged in a ring array. The driven parts are installed on the inner wall of the auxiliary cylinder. There are also multiple adjustment components, which are evenly distributed along the axial direction of the auxiliary cylinder.

[0015] The driven part rotates synchronously with the auxiliary cylinder. The rotating driven part passes through the driving part and is connected to the driving part in a transmission manner, thereby pushing the adjusting combing part on the driven part to extend and retract radially along the auxiliary cylinder.

[0016] In this technical solution, the drive unit includes a support rod arranged radially along the auxiliary cylinder. The support rod is fixed on the bottom side wall of the bearing shaft, and the extension line of the end of the support rod passes through the central axis of the main cylinder and is arranged perpendicular to the central axis of the main cylinder. A drive guide is fixed on the end of the support rod, and an arc-shaped drive guide surface is provided on the surface of the drive guide. The driven member passing through the arc-shaped drive guide surface is pushed and moved.

[0017] In this technical solution, the driven part includes a movable rod arranged radially along the auxiliary cylinder. The movable rod is slidably connected to the surface of the guide sleeve, and the guide sleeve is fixed to the inner wall of the auxiliary cylinder by a fixing frame. A driven guide is fixed on the end of the movable rod near the bearing shaft. The driven guide is provided with an arc-shaped driven guide surface that can overlap with the drive guide surface.

[0018] The other end of the moving rod is fixed to a deformable sealing cover and is fixedly connected to the adjusting comb through the sealing cover;

[0019] A spring is fitted onto the surface of the moving rod, and the two ends of the spring are fixed to the moving rod and the guide sleeve, respectively.

[0020] In this technical solution, the sealing cover includes a connecting shell, which covers the mounting groove on the side wall of the auxiliary cylinder. A connecting block is provided at the center of the connecting shell, and the two sides of the connecting block are fixedly connected to the moving rod and the adjusting comb respectively.

[0021] The connecting block is connected to the connecting shell through a deformable layer, and covers the gap between the connecting block and the connecting shell.

[0022] The connecting shell is flush with or slightly protrudes from the outer wall of the auxiliary cylinder.

[0023] This technical solution also includes multiple flow guiding components that are equally spaced along the circumference of the auxiliary cylinder. Each flow guiding component can rotate synchronously with the auxiliary cylinder. When the flow guiding component rotates with the auxiliary cylinder to the side closer to the main cylinder, its structural channel or flow guiding surface can guide and compress the surrounding air, thereby forming a directional micro airflow in a local area. The micro airflow blows to the fiber layer area corresponding to the surface of the main cylinder.

[0024] In this technical solution, the flow guiding component includes a follower and an airflow generating part. The follower is fixed on the bearing shaft, and the airflow generating part is fixed on the inner wall of the auxiliary cylinder. The airflow generating part rotates with the auxiliary cylinder, and one end of it moves on the follower. After moving to the side of the main cylinder, it generates an airflow that blows towards the surface of the main cylinder.

[0025] In this technical solution, the follower part includes at least one guide rail, which is fixed on the bearing shaft. The guide rail is generally ring-shaped, and its bottom side near the main cylinder protrudes outward to form a driving end. A mounting horizontal shaft is provided on one side of the guide rail. A slider is fixed on the end of the mounting horizontal shaft near the corresponding guide rail. The slider is slidably connected to the guide rail. The mounting horizontal shaft is fixedly connected to the airflow generating part.

[0026] The horizontal shaft, as it passes through the drive end, drives the airflow generator to produce airflow.

[0027] Specifically, the guide rail is coaxially arranged with the bearing shaft, and the guide rail is fixed to the bearing shaft by the first connecting rod.

[0028] In this technical solution, the airflow generating unit includes a cylindrical pressurized shell, which is fixed to the inner wall of the auxiliary cylinder by a second connecting rod. A guide pipe is connected to one end of the pressurized shell, and the guide pipe passes through the side wall of the auxiliary cylinder and is fixedly connected to the guide shroud.

[0029] A piston plate is slidably connected to the inner wall of the pressure shell. A transmission rod is fixed on the outer wall of the piston plate away from the guide tube. The transmission rod is fixed on the mounting horizontal shaft. The transmission rod, guide tube and pressure shell are all collinear and arranged radially along the auxiliary cylinder.

[0030] Specifically, the slider is preferably cylindrical. The piston plate and the inner wall of the pressure shell are connected by a sliding seal.

[0031] A fabric combing process, the process steps are as follows:

[0032] Step 1: Fiber feeding. The cashmere fibers to be combed are conveyed to the combing area formed between the main cylinder and the auxiliary cylinder through the feeding mechanism, so that the fibers first come into contact with the main combing parts on the surface of the main cylinder and are gripped and driven.

[0033] Step 2: Primary opening and main combing. Under the high-speed rotation of the main cylinder, the fibers unfold along the surface of the main cylinder and form a fiber layer. At the same time, the auxiliary cylinder rotates synchronously. The auxiliary combing parts on its surface mesh with the main combing parts to comb the fiber bundle in multiple directions, so that the fibers gradually loosen and tend to be arranged in parallel, thus achieving primary opening.

[0034] Step 3: Flexible adjustment of the combing mechanism. During the rotation of the auxiliary cylinder, the adjustment components inside the auxiliary cylinder drive the adjustment combing parts located on the surface of the auxiliary cylinder to periodically extend and retract.

[0035] When the adjusting carding part extends, it enters the gap area between the main carding part and the auxiliary carding part, applying secondary carding and disturbance to the fiber layer;

[0036] When the adjusting comb retracts, it creates a local clearance space, allowing the fibers to be released and rearranged, thereby reducing fiber breakage and short fiber generation caused by continuous strong gripping.

[0037] Step 4: Fiber web formation. After multi-stage flexible carding, the fibers gradually form a uniform and continuous fiber layer on the surface of the main cylinder and are transported to the fiber stripping area as the main cylinder rotates.

[0038] Step 5: Fiber web stripping and output. The doffer assembly located on the side of the main cylinder strips the fiber layer on the surface of the main cylinder at a low linear speed, so that the combed fiber web is smoothly transferred to the subsequent drawing or winding process, thereby completing the cashmere combing process.

[0039] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0040] The positive and progressive effects of this invention are as follows:

[0041] By incorporating retractable and adjustable combing elements on the adjustment assembly, which periodically extend and retract during the rotation of the auxiliary cylinder, a rhythmically varying flexible combing action is applied to the fiber layer. Compared to the traditional fixed-tooth continuous single combing method, this structure can create a dynamically changing combing force distribution during the rotation of the auxiliary cylinder, causing the fibers to be subjected to different degrees of grasping, disturbance, and release within different time windows. This helps to gradually disperse the fiber bundles and improve fiber parallelism, thereby enhancing the thoroughness of combing.

[0042] Furthermore, since the telescoping and adjusting combing element participates in secondary combing in the extended state and forms an avoidance space in the retracted state, it can effectively reduce the probability of fibers being continuously and strongly gripped, reduce fiber breakage and short fibers, and improve fiber length retention. At the same time, the telescoping action creates a micro-disturbance effect on the surface of the auxiliary cylinder, which can promote slight relative displacement and loose rearrangement of the fiber layer, preventing fibers from adhering or locally accumulating on the cylinder surface. This makes the fiber flow more uniform and smooth, which helps to improve yarn evenness and reduce periodic yarn evenness fluctuations.

[0043] In addition, the retractable combing component and the auxiliary cylinder fixed teeth form a synergistic combing relationship, realizing the superposition of the main combing force and the flexible adjustment force during the combing process. This transforms the combing action from a single rigid combing to a continuous and progressive composite combing process, which not only helps to improve the efficiency of removing coarse hair and loosening, but also reduces the instantaneous load and impact vibration of the equipment while ensuring sufficient combing, thereby improving the stability of operation and the reliability of continuous production.

[0066] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0067] like Figure 1 and Figure 2 As shown, a fabric combing device for cashmere garment processing includes a frame 1, on which a self-rotating cylindrical main cylinder 2 is installed. A self-rotating cylindrical auxiliary cylinder 3 is arranged on one side of the main cylinder 2. Multiple evenly distributed main combing components 21 and auxiliary combing components 31 are fixed on the annular surfaces of the main cylinder 2 and the auxiliary cylinder 3, and adjacent main combing components 21 and auxiliary combing components 31 are meshed with each other.

[0068] An adjustment component 5 is provided in the inner cavity of the auxiliary cylinder 3. When the auxiliary cylinder 3 rotates, the adjustment component 5 drives the adjustment combing member 523 located on the surface of the auxiliary cylinder 3 to extend and retract. The adjustment combing member 523 is located in the gap between the main combing member 21 and the auxiliary combing member 31.

[0069] Example 1

[0070] In this embodiment, as Figures 1-3 As shown, both sides of the main cylinder 2 are mounted on the frame 1, and a first transmission pulley 22 is fixed on the circular end face of one side of the main cylinder 2. The first transmission pulley 22 is connected to the corresponding drive motor, and the drive motor drives the main cylinder 2 to rotate.

[0071] Both sides of the auxiliary cylinder 3 are mounted on the frame 1. A second transmission pulley 33 is fixed on one end of the auxiliary cylinder 3. The second transmission pulley 33 is connected to the corresponding drive motor for transmission, and the drive motor drives the auxiliary cylinder 3 to rotate.

[0072] The first transmission pulley 22 and the second transmission pulley 33 are connected to the corresponding motors, thereby driving the main cylinder 2 and the auxiliary cylinder 3 to rotate.

[0073] Example 2

[0074] like Figure 9 and Figure 13 As shown, the auxiliary cylinder 3 is a hollow cylindrical shell structure, and a connecting pipe 32 is fixed on both circular end faces of the auxiliary cylinder 3. The connecting pipe 32 is connected to the inner cavity of the auxiliary cylinder 3, and the second transmission pulley 33 is sleeved and fixed on the corresponding connecting pipe 32.

[0075] The bearing shaft 4 is inserted into the inner cavity of the auxiliary cylinder 3. The auxiliary cylinder 3 can rotate on the bearing shaft 4, and its two ends protrude from the corresponding ends of the connecting tube 32. The two ends of the bearing shaft 4 are fixed to the frame 1 by the connecting bracket 42. The bearing shaft 4 and the auxiliary cylinder 3 are coaxially arranged.

[0076] A connecting cover 41 is sleeved and fixed to the end of the bearing shaft 4. The end of the connecting pipe 32 is engaged inside the annular groove of the connecting cover 41, and the connecting pipe 32 rotates inside the annular groove. The connecting cover 41 supports the connecting pipe 32.

[0077] like Figure 6 , Figure 13 and Figure 14 As shown, the adjustment assembly 5 includes a driving part 51 and a driven part 52. The driving part 51 is disposed on the bearing shaft 4. There are multiple driven parts 52, which are arranged in a ring array. The driven parts 52 are installed on the inner wall of the auxiliary cylinder 3. There are also multiple adjustment assemblies 5, which are evenly distributed along the axial direction of the auxiliary cylinder 3.

[0078] The driven part 52 rotates synchronously with the auxiliary cylinder 3. The rotating driven part 52 passes through the drive part 51 and is connected to the drive part 51 in a transmission manner, thereby pushing the adjusting combing member 523 on the driven part 52 to extend and retract radially along the auxiliary cylinder 3.

[0079] Specifically, the drive unit 51 includes a support rod 511 arranged radially along the auxiliary cylinder 3. The support rod 511 is fixed on the bottom side wall of the bearing shaft 4, and the extension line of the end of the support rod 511 passes through the central axis of the main cylinder 2 and is arranged perpendicular to the central axis of the main cylinder 2. A drive guide 512 is fixed on the end of the support rod 511. The surface of the drive guide 512 is provided with an arc-shaped drive guide surface, and the driven member is pushed and moved through the arc-shaped drive guide surface.

[0080] Furthermore, the driven part 52 includes a movable rod 521 arranged radially along the auxiliary cylinder 3. The movable rod 521 is slidably connected to the surface of the guide sleeve 524, and the guide sleeve 524 is fixed to the inner wall of the auxiliary cylinder 3 by a fixing bracket 525. A driven guide 527 is fixed on the end of the movable rod 521 near the bearing shaft 4. The driven guide 527 is provided with an arc-shaped driven guide surface that can overlap with the drive guide surface.

[0081] The other end of the moving rod 521 is fixed to a deformable sealing cover and is fixedly connected to the adjusting comb 523 through the sealing cover;

[0082] A spring is fitted onto the surface of the moving rod 521, and the two ends of the spring are fixed to the moving rod 521 and the guide sleeve 524, respectively.

[0083] Both the driving guide surface and the driven guide surface are axially symmetrical structures with the support rod 511 and the moving rod 521 as the axes of symmetry, respectively. The driving guide 512 and the driven guide 527 are both block structures. When the spring does not deform, the moving rod 521 and the adjusting comb 523 are in a contracted state.

[0084] Preferably, the ends of the moving rods 521 on adjacent driven parts 52 are connected by a synchronizing rod, so that each moving rod 521 can achieve linkage and synchronization during movement, thereby ensuring that the extension and retraction movements of multiple adjusting combing parts 523 have consistent rhythm and stability. Based on this, driven guides 527 are fixedly provided on the ends of only one or several equally spaced moving rods 521, and driving parts are provided at the corresponding driven moving parts, so that synchronous driving and displacement transmission of the entire group of moving rods 521 can be achieved with a small number of driving sources.

[0085] Through the above structural arrangement, on the one hand, the number of driving and guiding components can be reduced, making the overall structure of the adjustment component 5 simpler and more compact, reducing manufacturing and assembly difficulties, and reducing the coordination links in the transmission chain, which is conducive to improving motion reliability and reducing the probability of failure. On the other hand, with the help of the force transmission of the synchronizing rod, each adjusting combing component 523 can maintain a relatively consistent expansion and contraction phase relationship during the rotation of the auxiliary cylinder 3, thereby forming a more continuous and uniform flexible combing effect, which helps to improve the stress state of the fiber layer and enhance combing stability.

[0086] More preferably, one end face of the auxiliary cylinder 3 is designed as a detachable structure, such as an end cap secured by a flange or bolts, allowing the bearing shaft 4 to extend into the inner cavity of the auxiliary cylinder 3 from this end and connect with the internal adjusting assembly 5. Designing the end face as detachable significantly improves the convenience of assembly and maintenance, facilitating the installation, replacement, or repair of the internal telescopic mechanism, synchronizing rod assembly, and related transmission components. It also avoids extensive disassembly of the auxiliary cylinder 3 structure, thereby reducing downtime and maintenance costs. Furthermore, this structure allows for modular arrangement of the internal space while ensuring the overall strength and dynamic balance of the auxiliary cylinder 3, which is beneficial for improving equipment operational stability and long-term reliability.

[0087] As the driven guide 527 rotates with the auxiliary cylinder 3, the end of the driven guide surface on the driven guide 527 comes into contact with the end of the driving guide surface, thereby pushing the driven guide 527 to move outward. The driven guide 527 drives the moving rod 521 and the adjusting comb 523 to move outward synchronously. At this time, the spring deforms.

[0088] When the apex of the driven guide surface and the driving guide surface come into contact with each other, the adjusting combing component 523 moves outward to its limit position. Then, under the elastic force of the spring restoring deformation, the guide rod and the adjusting combing component 523 reset and retract.

[0089] The sealing cover includes a connecting shell 526, which covers the mounting groove 34 on the side wall of the auxiliary cylinder 3. A connecting block 522 is provided at the center of the connecting shell 526, and the two sides of the connecting block 522 are fixedly connected to the moving rod 521 and the adjusting comb 523, respectively.

[0090] The connecting block 522 is connected to the connecting shell 526 via a deformable layer 5261, and covers the gap between the connecting block 522 and the connecting shell 526.

[0091] The connecting shell 526 is flush with or slightly protrudes from the outer wall of the auxiliary cylinder 3.

[0092] The main combing component 21, the auxiliary combing component 31, and the adjusting combing component 523 have similar shapes but different dimensions. The geometric dimensions of the main combing component 21 and the auxiliary combing component 31 are the same, or one of them is larger than the other, while the geometric dimensions of the auxiliary combing components are all smaller than those of the main combing component 21 and the auxiliary combing component 31. When the main combing component 21 and the auxiliary combing component 31 are rod-shaped, the adjusting combing component 523 is also rod-shaped; when the main combing component 21 and the auxiliary combing component 31 are tooth-shaped, the adjusting combing component 523 is also tooth-shaped.

[0093] Example 3

[0094] like Figures 11-15It also includes multiple flow guiding components 6 arranged at equal intervals along the circumference of the auxiliary cylinder 3. Each flow guiding component 6 can rotate synchronously with the auxiliary cylinder 3. When the flow guiding component 6 rotates with the auxiliary cylinder 3 to the side close to the main cylinder 2, its structural channel or flow guiding surface can guide and compress the surrounding air, thereby forming a directional micro airflow in a local area. The micro airflow blows to the fiber layer area corresponding to the surface of the main cylinder 2.

[0095] By arranging the aforementioned flow guiding components 6 around the auxiliary cylinder 3, a pulsating micro-airflow is periodically generated during rotation. This micro-airflow slightly loosens, lifts, and disturbs the fiber layer attached to the surface of the main cylinder 2, thereby reducing fiber adhesion to the cylinder carding and promoting further dispersion and rearrangement of the fiber bundles. This improves fiber openness and combing efficiency. Simultaneously, the micro-airflow also assists in the detachment and migration of short fibers and impurities, reducing the probability of local fiber accumulation or entanglement, resulting in smoother and more uniform fiber layer flow. This, in turn, helps improve yarn evenness and reduce periodic yarn evenness fluctuations.

[0096] Furthermore, the airflow generated by the guide component 6 can work in synergy with the retractable and adjustable carding element 523 mounted on the auxiliary cylinder 3. When the adjustable carding element 523 is extended and participates in secondary carding, the airflow generated by the guide component 6 can assist in dispersing the disturbed fiber layer, making it easier for the fibers to loosen and rearrange during force changes. When the adjustable carding element 523 retracts to create clearance space, the micro-airflow helps to push the fibers away from the local gripping area, reducing the risk of the fibers being continuously and forcefully clamped. Through the above-mentioned combined mechanism of "flexible mechanical carding + airflow disturbance", the carding force distribution can be made more continuous and gentle, reducing fiber damage and short fiber generation while ensuring the carding effect, and further improving the stability of the overall machine operation and the comprehensive performance of the carding process.

[0097] The flow guiding component 6 includes a follower and an airflow generating part. The follower is fixed on the bearing shaft 4, and the airflow generating part is fixed on the inner wall of the auxiliary cylinder 3. The airflow generating part rotates with the auxiliary cylinder 3, and one end of it moves on the follower. After moving to the side of the main cylinder 2, it generates an airflow that blows towards the surface of the main cylinder 2.

[0098] The follower includes at least one guide rail 61, which is fixed on the bearing shaft 4. The guide rail 61 is generally ring-shaped, and its bottom protrudes outward on the side near the main cylinder 2 to form a drive end. A mounting horizontal shaft 62 is provided on one side of the guide rail 61. A slider 621 is fixed on the end of the mounting horizontal shaft 62 near the corresponding guide rail 61. The slider 621 is slidably connected to the guide rail 61. The mounting horizontal shaft 62 is fixedly connected to the airflow generating part.

[0099] The horizontal axis 62 drives the airflow generator to produce airflow as it passes through the drive end.

[0100] The guide rail 61 is coaxially arranged with the bearing shaft 4, and the guide rail 61 is fixed on the bearing shaft 4 by the first connecting rod 611.

[0101] The airflow generating unit includes a cylindrical pressurized shell 67, which is fixed to the inner wall of the auxiliary cylinder 3 by a second connecting rod 671. A guide pipe 65 is connected to one end of the pressurized shell 67, and the guide pipe 65 passes through the side wall of the auxiliary cylinder 3 and is fixedly connected to the guide cover 66.

[0102] A piston plate 64 is slidably connected to the inner wall of the pressure shell 67. A transmission rod 63 is fixed on the outer wall of the piston plate 64 away from the guide tube 65. The transmission rod 63 is fixed on the mounting horizontal shaft 62. The transmission rod 63, the guide tube 65 and the pressure shell 67 are all collinear and arranged radially along the auxiliary cylinder 3.

[0103] The pressure shell 67, the transmission rod 63, and the mounting horizontal shaft 62 fixedly connected to the transmission rod 63 rotate with the auxiliary cylinder 3. The mounting horizontal shaft 62 slides on the guide rail 61 with the slider 621 in a fixed position. When sliding on the circular structure of the guide rail 61, the piston plate 64 is located inside the pressure shell 67 on the side away from the guide tube 65 until the slider 621 slides to the drive end. As a result, the slider 621 moves towards the side closer to the guide tube 65 and the main cylinder 2, thereby pushing the piston plate 64 to move synchronously through the transmission rod 63, forcing the air inside the pressure shell 67 into the guide tube 65. The generated micro-airflow is transported from the guide shell to the surface of the main cylinder 2.

[0104] The guide rail 61 in the drive end area is also an arc-shaped structure, which is smoothly connected to other areas of the guide rail 61.

[0105] Specifically, the slider 621 is preferably cylindrical. The piston plate 64 and the inner wall of the pressure shell 67 are connected by a sliding seal.

[0106] Preferably, the surface of the flow guide 66 is covered with a filter screen to prevent fibers from entering the flow guide tube 65. One-way valves are provided on the outer walls of both the flow guide tube 65 and the pressurized housing 67 near the flow guide tube 65. The one-way valve on the flow guide tube 65 prevents gas from entering the pressurized housing 67 through the flow guide tube 65, while the guide valve on the pressurized housing 67 allows gas to enter the pressurized housing 67 through the one-way valve.

[0110] Example 4

[0111] A fabric combing process, the process steps are as follows:

[0112] Step 1: Fiber Feeding

[0113] The cashmere fibers to be combed are conveyed to the combing area formed between the main cylinder 2 and the auxiliary cylinder 3 through the feeding mechanism, so that the fibers first come into contact with the main combing component 21 on the surface of the main cylinder 2 and are gripped and driven.

[0114] Step 2: Primary opening and main combing

[0115] Under the high-speed rotation of the main cylinder 2, the fibers unfold along the surface of the main cylinder 2 and form a fiber layer. At the same time, the auxiliary cylinder 3 rotates synchronously, and the auxiliary carding part 31 on its surface meshes with the main carding part 21 to comb the fiber bundle in multiple directions, so that the fibers gradually loosen and tend to be arranged in parallel, thus achieving primary opening.

[0116] Step 3: Flexible adjustment of combing

[0117] During the rotation of the auxiliary cylinder 3, the adjustment component 5 in the inner cavity drives the adjustment comb 523 located on the surface of the auxiliary cylinder 3 to periodically extend and retract:

[0118] When the adjusting carding element 523 extends, it enters the gap area between the main carding element 21 and the auxiliary carding element 31, and applies secondary carding and disturbance to the fiber layer.

[0119] When the adjusting comb 523 retracts, it creates a local clearance space, allowing the fibers to be released and rearranged, thereby reducing fiber breakage and short fiber generation caused by continuous strong gripping.

[0120] Step 4: Fiber web formation

[0121] After being combed through multiple stages, the fibers gradually form a uniform and continuous fiber layer on the surface of the main cylinder 2, and are transported to the fiber stripping area as the main cylinder 2 rotates.

[0122] Step 5: Fiber web stripping and output

[0123] The doffer assembly located on the side of the main cylinder 2 strips the fiber layer on the surface of the main cylinder 2 at a low linear speed, so that the combed fiber web is smoothly transferred to the subsequent drawing or winding process, thereby completing the cashmere combing process.

[0124] The doffer assembly used to strip the fiber web formed on the surface of the main cylinder 2 and transport it to subsequent processes, as well as the related transmission and load-bearing structures for fiber feeding and output, can all be set in the corresponding positions of the frame 1 according to the conventional structural form of existing carding equipment. Since the specific form of the above structure does not substantially affect the realization of the carding mechanism and flexible carding principle of this application, and is a well-known technical means that is easily obtained by those skilled in the art, it will not be shown separately in the accompanying drawings.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
