Description

Technical Field

[0001] This invention relates to the field of new technologies in ring spinning, specifically to a self-cleaning aggregate spinning device and spinning method. Background Technology

[0002] Compact spinning, also known as concentrated spinning, is a new spinning technology that uses an improved ring spinning frame. It improves yarn quality by adding a fiber-condensing zone before the traction device on the ring spinning frame. Currently, the mainstream compact spinning types used internationally include mesh loop type (mainly the German Sussen three-roller mesh loop type and the Japanese Toyota four-roller mesh loop type), roller type (Rieter's COM4 from Switzerland), perforated apron type (mainly the Zinser perforated apron type), and mechanical type (mainly the Swiss Carlos Rosscraft magnetic concentrated compact spinning system). Mesh loop, roller, and perforated apron types all utilize negative pressure airflow concentration. Among these, Rosscraft's mechanical concentrated compact spinning system is less commonly used in China due to its poor adaptability (generally only suitable for spinning yarns below 60Ne); Zinser's perforated apron type is also less widely used in China due to its poor adaptability (generally only suitable for wool spinning) and the need for complete machine import, resulting in high prices (average 1500 RMB per spindle). Currently, the mainstream compact spinning system is the mesh loop type. However, this type of compact spinning system generally suffers from problems such as high modification and maintenance costs, high energy consumption, and difficulty in controlling the aggregation effect. Roller-type compact spinning has good control over hairiness, especially in effectively removing long harmful hairiness while retaining beneficial short hairiness. However, this type of compact spinning directly uses large-diameter hollow rollers with mesh or narrow grooves as aggregation elements. Therefore, it is prone to clogging during use, which seriously affects the aggregation effect.

[0003] To address this issue, the present invention provides a self-cleaning compact spinning device and spinning method. By setting a self-cleaning compact device including a compacting insert and a cleaning insert inside a large-diameter hollow roller, and connecting the two through an airflow-driven device, the negative pressure compaction of the upper part of the hollow roller and the positive pressure cleaning of the lower part of the hollow roller can be achieved simultaneously, thereby effectively solving the clogging problem in the use of roller-type compact spinning and improving the compaction effect. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning compact spinning device and spinning method. By setting a self-cleaning compact device including a compacting insert and a cleaning insert inside a large-diameter hollow roller, the clogging problem in the use of roller-type compact spinning is effectively solved and the compacting effect is improved.

[0005] To achieve the above objectives, the present invention relates to a self-cleaning, compacting spinning apparatus, comprising a front and rear spinning table with identical structures. Each front and rear spinning table includes 500-1000 identical spindles arranged horizontally along their length. Each spindle includes a drafting system. Along the fiber's movement direction within the drafting system, from back to front, the drafting system sequentially includes a rear drafting roller pair, a middle drafting roller pair, and a front drafting roller pair. The rear, middle, and front drafting roller pairs have identical structures, including an upper drafting roller and a lower drafting roller. The upper drafting rollers of the stretching roller pair and the front drafting roller pair have the same structure. The lower drafting roller includes a roller shaft, which is a solid steel cylinder. The lower drafting rollers of the rear drafting roller pair and the middle drafting roller pair have the same structure. A roller sleeve is provided on the roller shaft of the lower drafting roller of the rear drafting roller pair and the middle drafting roller pair. The roller sleeve has a ring structure, and the material of the roller sleeve is the same as that of the roller shaft. The inner diameter of the roller sleeve is the same as that of the roller shaft. The roller sleeve passes through the roller shaft and the two are integrally fixedly connected. A hollow sleeve is provided on the roller shaft of the lower drafting roller of the front drafting roller pair. The hollow sleeve is hollow. The hollow sleeve, an open-ended cylindrical shape, is made of the same material as the roller shaft, with its inner diameter larger than the outer diameter. It has collecting holes or grooves that are evenly spaced along its width to form rows of collecting holes. These rows maintain a certain distance from both ends of the hollow sleeve. Two adjacent rows of collecting holes form a working group. Within this working group, the length of the first row of collecting holes is less than the length of the second row, and the distance between the first and second rows of collecting holes is... Aligned on the right, each aggregation hole group is arranged at equal arc intervals along the circumference of the hollow sleeve. The aggregation grooves are arranged along the width of the hollow sleeve, and a certain distance is maintained between the aggregation grooves and the two ends of the hollow sleeve. Each aggregation groove is arranged at equal arc intervals along the circumference of the hollow sleeve. An upper control roller is arranged in front of the upper drafting roller of the front drafting roller pair. The upper control roller has the same structure as the upper drafting roller. The upper control roller presses on the hollow sleeve of the lower drafting roller of the front drafting roller pair. The area above the hollow sleeve between the upper drafting roller and the upper control roller forms the aggregation zone.

[0006] Two adjacent spindle positions constitute a spindle position work group. The left side of the hollow sleeve of the lower drawing roller of the left spindle position and the right side of the hollow sleeve of the lower drawing roller positioned on the right side of the work group are fixedly connected to the corresponding roller shafts via retaining rings. This allows the right side of the hollow sleeve of the lower drawing roller of the left spindle position and the left side of the hollow sleeve of the lower drawing roller positioned on the right side of the work group to be open. A left and right sliding groove are formed along the inner surface of the hollow sleeve, maintaining a certain distance between them. The left and right sliding grooves are arranged along a circumferential direction of the inner surface of the hollow sleeve and are kept smooth. The right side of the hollow sleeve of the lower drawing roller of the left spindle position and the right side of the hollow sleeve of the lower drawing roller positioned on the right side of the work group are also open. A self-cleaning gathering device is installed in the area between the left sides of the hollow sleeve. This device includes a gathering insert and a cleaning insert. The gathering insert is located in the area between the hollow sleeve and the roller shaft. The gathering insert includes an upper gathering arc surface and a lower gathering arc surface, both of which are arc-shaped structures. The curvature of the lower gathering arc surface is greater than that of the upper gathering arc surface. The upper gathering arc surface is parallel to the inner surface of the hollow sleeve. The front, rear, left, and right sides of the upper and lower gathering arc surfaces are connected by a front gathering sealing plate, a rear gathering sealing plate, a left gathering sealing plate, and a right gathering sealing plate, respectively, forming a complete hollow and closed gathering insert. An upper left sliding plate is fixedly installed on the upper left side of the gathering upper arc surface of the gathering insert. An upper right slider is fixedly installed on the upper right side of the upper arc surface of the aggregation plug. Both the upper left and upper right sliders are smooth and arc-shaped structures parallel to the upper arc surface. The thickness of the upper left slider is equal to the depth of the left groove, and the thickness of the upper right slider is equal to the depth of the right groove. The upper left slider is completely embedded in the left groove, maintaining smooth contact, and the upper right slider is completely embedded in the right groove, maintaining smooth contact. This ensures that the upper arc surface and the inner surface of the hollow sleeve remain in close contact. An aggregation slot is opened at the center of the upper arc surface, directly opposite the hollow sleeve in the aggregation area. The upper and lower sides of the aggregation slot are straight, with the upper side being longer than the lower side. The right end of the upper side is connected to the lower... The right ends of the sides are vertically aligned, making the right side of the agglomeration slot straight. The left ends of the upper and lower sides of the agglomeration slot are connected by an arc-shaped left side, so that the width of the agglomeration slot first decreases and then increases from top to bottom along its length. Negative pressure air inlets are opened on the left agglomeration sealing surface of the left agglomeration plug and the right agglomeration sealing surface of the right agglomeration plug in a spindle work group. A negative pressure connecting pipe is installed between the left agglomeration sealing surface of the left agglomeration plug and the right agglomeration sealing surface of the right agglomeration plug in a spindle work group. The two ends of the negative pressure connecting pipe are interconnected with the negative pressure air inlets of the left agglomeration plug and the right agglomeration plug in a spindle work group, respectively.

[0007] An upward connector, rectangular in shape, is located midway along the length of the negative pressure connecting pipe. One end of the upward connector is fixedly connected to the negative pressure connecting pipe via an arc-shaped fixing piece. The other end of the upward connector has a first pin and a second pin, both fixedly positioned on its end face. A fixed connector, rectangular in shape and made of rigid plastic, is located on the platform opposite the upward connector. The side of the fixed connector facing the platform is adhered to it, while the side facing away from the platform has a first slot and a second slot. The first and second pins of the upward connector are respectively embedded in the first and second slots of the fixed connector, thus securing the self-cleaning collection device.

[0008] The cleaning insert is located in the area between the hollow sleeve and the roller shaft, directly below the accumulating insert. The cleaning insert includes an upper and lower curved cleaning surface, both of which are curved and parallel. The lower curved cleaning surface is parallel to the inner surface of the hollow sleeve. The front, rear, left, and right sides of the upper and lower curved cleaning surfaces are connected by a front, rear, left, and right cleaning sealing plate, respectively, forming a complete hollow and sealed cleaning insert. The plug-in has a lower left slider fixedly mounted on the lower left side of the lower curved surface of the cleaning plug-in, and a lower right slider fixedly mounted on the lower right side of the lower curved surface of the cleaning plug-in. Both the lower left and lower right sliders are smooth, arc-shaped structures that are parallel to the lower curved surface of the cleaning plug-in. The thickness of the lower left slider is equal to the depth of the left groove, and the thickness of the lower right slider is equal to the depth of the right groove. The lower left slider is completely embedded in the left groove, and the two maintain smooth contact. The lower right slider is completely embedded in the right groove, and the two maintain smooth contact. To ensure a tight fit between the lower curved surface and the inner surface of the hollow sleeve, a set of cleaning holes is provided in the middle of the curved section of the lower curved surface. This set includes a first row, a second row, and a third row of cleaning holes, each containing a certain number of cleaning holes. The cleaning holes are evenly spaced along the width of the lower curved surface, and their diameter is less than 3mm. The cleaning holes in the first, second, and third rows are staggered along the width of the lower curved surface. This ensures complete, non-repeating coverage of the lower arc surface during cleaning. Positive pressure air inlets are located on the left and right cleaning surfaces of the left and right spindle cleaning plugs in a spindle work group, respectively. A positive pressure connecting pipe is installed between the left and right cleaning surfaces of the left and right spindle cleaning plugs in a spindle work group, with both ends connected to the positive pressure air inlets of the left and right spindle cleaning plugs, respectively.

[0009] A negative pressure inlet is located midway along the length of the negative pressure connecting pipe, and a negative pressure filter is installed at the negative pressure inlet. Similarly, a positive pressure inlet is located midway along the length of the positive pressure connecting pipe, and a positive pressure filter is installed at the positive pressure inlet. The filter holes of the positive pressure filter are larger than those of the negative pressure filter. An interconnecting connecting pipe, which is spherical in shape, is installed between the negative and positive pressure inlets. Both the negative and positive pressure outlets are the same size and aligned with the negative pressure inlet, thus achieving interconnection between the two pipes. An airflow-driven fan is installed within the interconnecting connecting pipe. An airflow-driven shaft is located at the center of the airflow-driven fan. The airflow-driven shaft extends from the lower part of the interconnecting pipe, and a connecting bearing is installed at the part of the airflow-driven shaft extending out of the interconnecting pipe, allowing the airflow-driven shaft to rotate freely while keeping the part of the airflow-driven shaft extending out of the interconnecting pipe closed. An airflow-driven wheel is installed at one end of the airflow-driven shaft extending out of the interconnecting pipe, and the airflow-driven wheel is fixedly connected to the airflow-driven shaft. The airflow-driven wheels of each spindle position on the front carriage platform are interconnected through a front drive belt. The front drive belt has an S-shaped structure and connects the airflow-driven wheels of each spindle position on the front carriage platform in sequence. The airflow-driven wheels of each spindle position on the rear carriage platform are interconnected through a rear drive belt. The rear drive belt has an S-shaped structure and connects the airflow-driven wheels of each spindle position on the rear carriage platform in sequence. The rear drive belt and the front drive belt are driven by an airflow-driven motor.

[0010] In use, the self-cleaning and gathering devices of each spindle group are fixed. The first and second pins of the upward connecting parts of the self-cleaning and gathering device are then inserted into the first and second slots of the fixing connecting parts at their respective positions. The gathering insert is positioned at the upper part of the area between the hollow sleeve and the roller shaft, and the cleaning insert is positioned at the lower part of the area between the hollow sleeve and the roller shaft. Then, a front drive belt in an S-shape connects the airflow drive wheels of each spindle on the front table, and a rear drive belt in an S-shape connects the airflow drive wheels of each spindle on the rear table. This completes the installation of the self-cleaning and gathering device for a spinning frame. The airflow drive motor drives the rear and front drive belts to rotate, thereby driving the rotation of each spindle group. The airflow from the self-cleaning gathering device drives the shaft to rotate, which in turn drives the corresponding airflow to rotate the fan. Under the rotation of the fan, the airflow flows from the negative pressure connecting pipe towards the positive pressure connecting pipe. This airflow causes external airflow to sequentially enter the negative pressure connecting pipe through the gathering holes or grooves, thus forming a negative pressure gathering airflow above the hollow sleeve. During the formation of this negative pressure gathering airflow, external airflow flows into the hollow sleeve through the left, right, and top sides of the gathering groove. Under the action of the negative pressure gathering airflow, the fiber strips located above the hollow sleeve are gathered. During this gathering process, the fiber strips cover the top of the hollow sleeve, thus partially blocking the airflow flowing in from above the gathering groove. At the rear of the gathering slot, due to the relatively loose fiber strands, the airflow flowing in from above the gathering slot is less obstructed. This airflow causes the fiber strands to adhere tightly to the surface of the hollow sleeve. At this time, under the influence of the airflow on the left side of the gathering slot, the left edge fibers of the fiber strand move to the right, and the right edge fibers move to the left, causing the fiber strands to converge towards the center. Due to the arc-shaped structure design on the left side of the gathering slot, the force of the fiber strand moving to the right is greater than the force moving to the left. As the fiber strands converge towards the center, the obstruction of the airflow flowing in from above the gathering slot gradually increases, thus causing the fiber strands to... The adhesion effect on the hollow sleeve is weakened, and at the same time, the distance between the gathered fiber sliver and the left and right sides of the gathering groove increases. Consequently, the airflow flowing in through the right and left sides of the gathering groove increases accordingly. Due to the straight structure of the right side, under the action of the airflow flowing in from the right side of the gathering groove, the fibers on the right edge of the fiber sliver move simultaneously along the direction perpendicular to the hollow sleeve and towards the left side of the fiber sliver. Due to the arc-shaped structure of the left side, under the action of the airflow flowing in from the left side of the gathering groove, the fibers on the left edge of the fiber sliver move simultaneously along the direction perpendicular to the back of the hollow sleeve and towards the right side of the fiber sliver. Under the combined effect of these two factors, the fibers within the fiber sliver undergo a tumbling and gathering action.This process further reduces the width of the fiber sliver while simultaneously imparting a certain degree of gathering twist, with the direction of this gathering twist aligned with the designed twist direction. As the width of the gathering groove gradually decreases, the fiber sliver is gradually gathered together. When the width of the gathering groove increases further, the gathering twist increases accordingly, thus providing a certain degree of stability to the gathering twist already applied to the fiber sliver. During the gathering process, some short fibers may adhere to the hollow sleeve, causing blockage of the gathering holes or grooves. The airflow from the outside enters through the interconnecting pipe into the positive pressure connecting pipe, then into the cleaning insert, and finally exits through the cleaning holes in the cleaning hole group on the lower arc surface. The ejected airflow blows off the fibers adhering to the hollow sleeve, thus achieving real-time cleaning of the hollow sleeve. The gathered fiber slivers leave the gathering area after passing through the pressing point between the upper control roller and the hollow sleeve. The fiber slivers that leave the gathering area are immediately twisted to the designed twist degree, thus obtaining the desired fine yarn. The resulting fine yarn is continuously wound onto the yarn tube.

[0011] This invention solves the clogging problem in roller-type compact spinning by setting a self-cleaning compaction device, including a compaction insert and a cleaning insert, inside a large-diameter hollow roller, with the two interconnected by an airflow-driven device. This simultaneously achieves negative pressure compaction at the top of the hollow roller and positive pressure cleaning at the bottom, thus effectively solving the clogging problem in roller-type compact spinning and improving the compaction effect.

[0015] A self-cleaning, compact spinning device includes a front and rear spinning table with identical structures. Each table comprises 500-1000 identical spindles arranged horizontally along their length. Each spindle includes a drafting system. Along the fiber's movement direction within the drafting system, from back to front, the system sequentially includes a rear drafting roller pair, a middle drafting roller pair, and a front drafting roller pair. These pairs are structurally identical, including an upper drafting roller and a lower drafting roller. The upper drafting rollers have the same structure. The lower drafting rollers include a roller shaft 1, which is a solid steel cylinder. The lower drafting rollers of the rear and middle drafting roller pairs have the same structure. Roller sleeves are provided on the roller shafts of the lower drafting rollers of the rear and middle drafting roller pairs. The roller sleeves are annular in structure, made of the same material as the roller shaft, and have the same inner diameter as the outer diameter. The roller sleeves are fitted onto the roller shafts and are integrally fixedly connected. A hollow sleeve 2 is provided on the roller shaft of the lower drafting rollers of the front drafting roller pair. The hollow sleeve is a hollow, open-ended circular shape. The cylinder is hollow, made of the same material as the roller shaft. The inner diameter of the hollow sleeve is larger than the outer diameter of the roller shaft. The hollow sleeve has either collecting holes or collecting grooves. These collecting holes are evenly spaced along the width of the hollow sleeve, forming rows of collecting holes. A certain distance is maintained between the rows of collecting holes and the two ends of the hollow sleeve. Two adjacent rows of collecting holes form a working group. The length of the first row of collecting holes within a working group is less than the length of the second row of collecting holes, and the right sides of the first and second rows of collecting holes are aligned. The working groups of the aggregation holes are arranged at equal arc intervals along the circumference of the hollow sleeve. The aggregation grooves are arranged along the width of the hollow sleeve, and a certain distance is maintained between the aggregation grooves and the two ends of the hollow sleeve. The aggregation grooves are arranged at equal arc intervals along the circumference of the hollow sleeve. An upper control roller is arranged in front of the upper drawing roller of the front drawing roller pair. The structure of the upper control roller is the same as that of the upper drawing roller. The upper control roller presses on the hollow sleeve of the lower drawing roller of the front drawing roller pair. The area above the hollow sleeve between the upper drawing roller and the upper control roller forms the aggregation zone.

[0016] Two adjacent spindle positions constitute a spindle position working group. The left side of the hollow sleeve of the lower drawing roller of the left spindle position and the right side of the hollow sleeve of the lower drawing roller of the right positioning spindle in a spindle position working group are fixedly connected to the corresponding roller shafts via retaining rings 5. This allows the right side of the hollow sleeve of the lower drawing roller of the left spindle position and the left side of the hollow sleeve of the lower drawing roller of the right positioning spindle within a spindle position working group to be open. A left and right sliding groove are formed along the inner surface of the hollow sleeve, maintaining a certain distance between them. The left and right sliding grooves are arranged along a circumferential direction of the inner surface of the hollow sleeve and are kept smooth. The right side of the hollow sleeve of the lower drawing roller of the left spindle position and the left side of the hollow sleeve of the lower drawing roller of the right positioning spindle within a spindle position working group are open. A self-cleaning gathering device 4 is provided in the area between the left and right sides of the hollow sleeve. The self-cleaning gathering device includes a gathering insert 6 and a cleaning insert 8. The gathering insert is located in the area between the hollow sleeve and the roller shaft. The gathering insert includes a gathering upper arc surface and a gathering lower arc surface. Both the gathering upper arc surface and the gathering lower arc surface are arc-shaped structures, and the curvature of the gathering lower arc surface is greater than that of the gathering upper arc surface. The gathering upper arc surface is parallel to the inner surface of the hollow sleeve. The front side, rear side, left side, and right side of the gathering upper arc surface and the gathering lower arc surface are connected by a front gathering sealing plate, a rear gathering sealing plate, a left gathering sealing plate, and a right gathering sealing plate, respectively, thus forming a complete hollow and closed gathering insert. An upper left sliding plate is fixedly provided on the upper left side of the gathering upper arc surface of the gathering insert. An upper right slider is fixedly installed on the upper right side of the upper arc surface of the aggregation plug. Both the upper left and upper right sliders are smooth and arc-shaped structures that are parallel to the upper arc surface. The thickness of the upper left slider is equal to the depth of the left groove, and the thickness of the upper right slider is equal to the depth of the right groove. The upper left slider is completely embedded in the left groove, and the two maintain smooth contact. The upper right slider is completely embedded in the right groove, and the two maintain smooth contact. This ensures that the upper arc surface of the aggregation plug and the inner surface of the hollow sleeve are in close contact. An aggregation slot 7 is opened at the center of the upper arc surface of the aggregation plug, and the aggregation slot is directly opposite the hollow sleeve of the aggregation area. The upper and lower sides of the aggregation slot are both straight, and the length of the upper side is greater than the length of the lower side. The right end of the upper side is connected to the lower side. The right ends of the sides are vertically aligned, making the right side of the agglomeration slot straight. The left ends of the upper and lower sides of the agglomeration slot are connected by the left side of the arc, so that the width of the agglomeration slot first decreases and then increases from top to bottom along the length of the agglomeration slot. Negative pressure air inlets are opened on the left agglomeration sealing surface of the left agglomeration plug and the right agglomeration sealing surface of the right agglomeration plug in a spindle work group. A negative pressure connecting pipe 10 is provided between the left agglomeration sealing surface of the left agglomeration plug and the right agglomeration sealing surface of the right agglomeration plug in a spindle work group. The two ends of the negative pressure connecting pipe are interconnected with the negative pressure air inlets of the left agglomeration plug and the right agglomeration plug in a spindle work group, respectively.

[0017] An upward connector 14 is provided at the middle of the length of the negative pressure connecting pipe. The upward connector is cuboid in shape. One end of the upward connector is fixedly connected to the negative pressure connecting pipe by an arc-shaped fixing piece. The other end of the upward connector is provided with a first pin 15 and a second pin 16. The first pin and the second pin are fixedly set on the end face of the other end of the upward connector. A fixing connector is provided on the platform directly opposite the upward connector. The fixing connector is a cuboid made of hard plastic. The side of the fixing connector facing the platform is pasted onto the platform. The side of the fixing connector facing away from the platform is provided with a first slot and a second slot. The first pin and the second pin of the upward connector are respectively embedded in the first slot and the second slot of the fixing connector, thereby realizing the fixation of the self-cleaning collection device.

[0018] The cleaning insert 8 is located in the area between the hollow sleeve and the roller shaft, and is directly below the accumulating insert. The cleaning insert includes an upper cleaning arc surface and a lower cleaning arc surface, both of which are arc-shaped and parallel. The lower cleaning arc surface is parallel to the inner surface of the hollow sleeve. The front, rear, left, and right sides of the upper and lower cleaning arc surfaces are connected by a front cleaning sealing plate, a rear cleaning sealing plate, a left cleaning sealing plate, and a right cleaning sealing plate, respectively, thus forming a complete hollow and closed cleaning insert. The cleaning insert has a lower left slider fixedly mounted on the lower left side of the lower curved surface, and a lower right slider fixedly mounted on the lower right side of the lower curved surface. Both the lower left and lower right sliders are smooth, arc-shaped structures parallel to the lower curved surface. The thickness of the lower left slider is equal to the depth of the left groove, and the thickness of the lower right slider is equal to the depth of the right groove. The lower left slider is completely embedded in the left groove, maintaining smooth contact between them, and the lower right slider is completely embedded in the right groove, maintaining smooth contact between them. This ensures that the lower curved surface of the cleaning device remains in close contact with the inner surface of the hollow sleeve. A group of cleaning holes is formed in the middle of the curved section of the lower curved surface. This group includes a first row, a second row, and a third row of cleaning holes, each containing a certain number of cleaning holes 9. The cleaning holes are evenly spaced along the width of the lower curved surface, and their diameter is less than 3mm. The cleaning holes in the first, second, and third rows are staggered along the width of the lower curved surface. The cleaning process completely covers one width of the lower arc surface without repetition. Positive pressure air inlets are opened on the left cleaning sealing surface of the left spindle cleaning plug and the right cleaning sealing surface of the right spindle cleaning plug in a spindle work group. A positive pressure connecting pipe 11 is provided between the left cleaning sealing surface of the left spindle cleaning plug and the right cleaning sealing surface of the right spindle cleaning plug in a spindle work group. The two ends of the positive pressure connecting pipe are interconnected with the positive pressure air inlets of the left spindle cleaning plug and the right spindle cleaning plug in a spindle work group, respectively.

[0019] A negative pressure connection inlet is located at the midpoint of the length of the negative pressure connection pipe, and a negative pressure connection filter is installed at the negative pressure connection port. Similarly, a positive pressure connection inlet is located at the midpoint of the length of the positive pressure connection pipe, and a positive pressure filter is installed at the positive pressure connection port. The filter holes of the positive pressure filter are larger than those of the negative pressure connection filter. An interconnecting connection pipe 12, which is spherical in shape, is installed between the negative and positive pressure connection ports. A negative pressure connection outlet and a positive pressure connection outlet are respectively opened on the interconnecting connection pipe. The negative pressure connection outlet and the negative pressure connection inlet are the same size and are aligned and fixedly connected, thus achieving interconnection between the interconnecting connection pipe and the negative pressure connection pipe. The positive pressure connection outlet and the positive pressure connection inlet are the same size and are aligned and fixedly connected, thus achieving interconnection between the interconnecting connection pipe and the positive pressure connection pipe. An airflow-driven fan 13 is installed inside the interconnecting connection pipe. An airflow drive shaft 17 is installed at the center of the airflow drive fan. The airflow drive shaft extends out from the lower part of the interconnecting pipe, and a connecting bearing 18 is installed at the part of the airflow drive shaft that extends out of the interconnecting pipe, so that the airflow drive shaft can rotate freely and the part of the airflow drive shaft that extends out of the interconnecting pipe remains closed. An airflow drive wheel 19 is installed at one end of the airflow drive shaft that extends out of the interconnecting pipe. The airflow drive wheel is fixedly connected to the airflow drive shaft. The airflow drive wheels of each spindle position on the front carriage platform are connected to each other through the front drive belt. The front drive belt has an S-shaped structure and connects the airflow drive wheels of each spindle position on the front carriage platform in sequence. The airflow drive wheels of each spindle position on the rear carriage platform are connected to each other through the rear drive belt. The rear drive belt has an S-shaped structure and connects the airflow drive wheels of each spindle position on the rear carriage platform in sequence. The rear drive belt and the front drive belt are driven by the airflow drive motor.

The first and second pins of the upward connecting parts of the self-cleaning and gathering device are then inserted into the first and second slots of the fixing connecting parts at their respective positions. The gathering insert is positioned at the upper part of the area between the hollow sleeve and the roller shaft, and the cleaning insert is positioned at the lower part of the area between the hollow sleeve and the roller shaft.

Due to the arc-shaped structure of the left side, under the action of the airflow flowing in from the left side of the gathering groove, the fibers on the left edge of the fiber sliver move simultaneously along the direction perpendicular to the back of the hollow sleeve and towards the right side of the fiber sliver. Under the combined effect of these two factors, the fibers within the fiber sliver undergo a tumbling and gathering action.This process further reduces the width of the fiber sliver while simultaneously imparting a certain degree of gathering twist, with the direction of this gathering twist aligned with the designed twist direction. As the width of the gathering groove gradually decreases, the fiber sliver is gradually gathered together. When the width of the gathering groove increases further, the gathering twist increases accordingly, thus providing a certain degree of stability to the gathering twist already applied to the fiber sliver. During the gathering process, some short fibers may adhere to the hollow sleeve, causing blockage of the gathering holes or grooves. The airflow from the outside enters through the interconnecting pipe into the positive pressure connecting pipe, then into the cleaning insert, and finally exits through the cleaning holes in the cleaning hole group on the lower arc surface. The ejected airflow blows off the fibers adhering to the hollow sleeve, thus achieving real-time cleaning of the hollow sleeve. The gathered fiber slivers leave the gathering area after passing through the pressing point between the upper control roller and the hollow sleeve. The fiber slivers that leave the gathering area are immediately twisted to the designed twist degree, thus obtaining the desired fine yarn. The resulting fine yarn is continuously wound onto the yarn tube.

10. The self-cleaning compact spinning method of the self-cleaning compact spinning device according to claim 1, characterized in that: In use, the self-cleaning and gathering devices of each spindle group are fixed. The first and second pins of the upward connecting parts of the self-cleaning and gathering device are then inserted into the first and second slots of the fixing connecting parts at their respective positions. The gathering insert is positioned at the upper part of the area between the hollow sleeve and the roller shaft, and the cleaning insert is positioned at the lower part of the area between the hollow sleeve and the roller shaft. Then, a front drive belt in an S-shape connects the airflow drive wheels of each spindle on the front table, and a rear drive belt in an S-shape connects the airflow drive wheels of each spindle on the rear table. This completes the installation of the self-cleaning and gathering device for a spinning frame. The airflow drive motor drives the rear and front drive belts to rotate, thereby driving the rotation of each spindle group. The airflow from the self-cleaning gathering device drives the shaft to rotate, which in turn drives the corresponding airflow to rotate the fan. Under the rotation of the fan, the airflow flows from the negative pressure connecting pipe towards the positive pressure connecting pipe. This airflow causes external airflow to sequentially enter the negative pressure connecting pipe through the gathering holes or grooves, thus forming a negative pressure gathering airflow above the hollow sleeve. During the formation of this negative pressure gathering airflow, external airflow flows into the hollow sleeve through the left, right, and top sides of the gathering groove. Under the action of the negative pressure gathering airflow, the fiber strips located above the hollow sleeve are gathered. During this gathering process, the fiber strips cover the top of the hollow sleeve, thus partially blocking the airflow flowing in from above the gathering groove. At the rear of the gathering slot, due to the relatively loose fiber strands, the airflow flowing in from above the gathering slot is less obstructed. This airflow causes the fiber strands to adhere tightly to the surface of the hollow sleeve. At this time, under the influence of the airflow on the left side of the gathering slot, the left edge fibers of the fiber strand move to the right, and the right edge fibers move to the left, causing the fiber strands to converge towards the center. Due to the arc-shaped structure design on the left side of the gathering slot, the force of the fiber strand moving to the right is greater than the force moving to the left. As the fiber strands converge towards the center, the obstruction of the airflow flowing in from above the gathering slot gradually increases, thus causing the fiber strands to... The adhesion effect on the hollow sleeve is weakened, and at the same time, the distance between the gathered fiber sliver and the left and right sides of the gathering groove increases. Consequently, the airflow flowing in through the right and left sides of the gathering groove increases accordingly. Due to the straight structure of the right side, under the action of the airflow flowing in from the right side of the gathering groove, the fibers on the right edge of the fiber sliver move simultaneously along the direction perpendicular to the hollow sleeve and towards the left side of the fiber sliver. Due to the arc-shaped structure of the left side, under the action of the airflow flowing in from the left side of the gathering groove, the fibers on the left edge of the fiber sliver move simultaneously along the direction perpendicular to the back of the hollow sleeve and towards the right side of the fiber sliver. Under the combined effect of these two factors, the fibers within the fiber sliver undergo a tumbling and gathering action.This process further reduces the width of the fiber sliver while simultaneously imparting a certain degree of gathering twist, with the direction of this gathering twist aligned with the designed twist direction. As the width of the gathering groove gradually decreases, the fiber sliver is gradually gathered together. When the width of the gathering groove increases further, the gathering twist increases accordingly, thus providing a certain degree of stability to the gathering twist already applied to the fiber sliver. During the gathering process, some short fibers may adhere to the hollow sleeve, causing blockage of the gathering holes or grooves. The airflow from the outside enters through the interconnecting pipe into the positive pressure connecting pipe, then into the cleaning insert, and finally exits through the cleaning holes in the cleaning hole group on the lower arc surface. The ejected airflow blows off the fibers adhering to the hollow sleeve, thus achieving real-time cleaning of the hollow sleeve. The gathered fiber slivers leave the gathering area after passing through the pressing point between the upper control roller and the hollow sleeve. The fiber slivers that leave the gathering area are immediately twisted to the designed twist degree, thus obtaining the desired fine yarn. The resulting fine yarn is continuously wound onto the yarn tube.
