Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, and in particular to a dust removal system for the middle section of a double-sided circular knitting machine. Background Technology

[0002] During the circular knitting process of textile fabrics such as cotton-padded sandwich fabrics, yarn friction and fiber shedding generate a large amount of dust. This dust easily accumulates in key parts of the knitting mechanism, affecting not only the fabric weaving quality but also accelerating the wear of equipment components and reducing the equipment's lifespan. Various dust removal mechanisms for circular knitting machines have emerged in the industry, primarily using an annular air delivery structure equipped with an air jet assembly to expand the dust removal range through rotational motion. However, existing dust removal mechanisms lack a high-precision coaxial centering structure, causing wobbling and misalignment during operation. Furthermore, the annular air delivery structure and supporting components often rely on sliding friction, which, after prolonged rotation, can easily lead to loosening due to wear, exacerbating the wobbling. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a mid-section dust removal system for a double-sided circular knitting machine, which can accurately center, rotate with low friction, provide uniform support, and has strong adaptability, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A double-sided circular mill mid-section dust removal system includes a circular air conveying ring. The air conveying ring has an internal airflow channel, and its outer wall has an air inlet and multiple evenly spaced air pipes. The air pipes communicate with the airflow channel. A retaining ring is located in the middle of the air conveying ring, coaxial with it. Multiple evenly spaced connecting rods are detachably mounted on the retaining ring. Support seats are detachably mounted on the ends of the connecting rods. The support seats have triangular protrusions on both sides, forming a triangular recess between two protrusions. Inclined perforations are provided through the sidewalls of the two protrusions, and bearings are fixedly connected within these perforations. The outer ring of the bearing protrudes from the surface of the recess. The bottom of the air conveying ring has a pointed angle and is movably positioned within the recess. The outer rings of the two bearings contact the two sidewalls of the air conveying ring, allowing the air conveying ring to slide within the recess.

[0005] Furthermore, the air supply ring is provided with a rack mounting groove, and a rack is detachably installed at the bottom of the rack mounting groove; a motor fixing plate is installed on the side wall of one of the support seats, and a motor is installed on the motor fixing plate. The motor shaft of the motor is set vertically upward and fixed with a gear, which meshes with the rack.

[0006] Furthermore, the gas supply ring includes a semi-circular gas supply segment one and a gas supply segment two. Each of the gas supply segment one and the gas supply segment two is provided with two airflow channels, namely airflow channel one and airflow channel two. The ends of the gas supply segment one and the gas supply segment two are respectively configured as interlocking slots and blocks. The bottom of the slot is provided with a vent hole one, and the inner side of the block is provided with a vent hole two. The positions of vent hole one and vent hole two are corresponding. The ends of airflow channel one and airflow channel two are blocked with sealing plugs. The block is correspondingly engaged with the slot. The ends of the gas supply segment one and the gas supply segment two are connected by locking screws to form a circular gas supply ring.

[0007] Furthermore, a sealing groove is provided on the outer edge of the second vent hole, and a sealing ring is provided in the sealing groove.

[0008] Furthermore, the air supply ring is provided with an insertion hole, which is connected to airflow channel one and airflow channel two. The end of the air tube is threadedly connected to the insertion hole, and the end of the air tube is threadedly connected to a nut on the outside of the insertion hole. The nut abuts against the outer wall of the air supply ring.

[0009] Furthermore, the bottom of the retaining ring is provided with multiple support pillars at even intervals.

[0010] Furthermore, the retaining ring includes two retaining ring segments with a semi-circular structure, and the two retaining ring segments are detachably connected by screws.

[0011] Furthermore, the retaining ring is provided with multiple retaining ring mounting holes, a connecting rod is inserted into the retaining ring mounting holes, and a locking screw is threaded to the bottom of the retaining ring. The end of the locking screw enters the retaining ring mounting hole and abuts tightly against the outer surface of the connecting rod.

[0012] Furthermore, the cross-section of the perforation is square, and a bearing fixing hole is provided at the top of the perforation. The bearing fixing hole extends to the bottom of the perforation, and the bearing is set inside the square structure. The bearing is fixed inside the perforation by a set screw that is threadedly connected to the bearing fixing hole and the inner ring of the bearing. Beneficial effects

[0013] Compared with the prior art, the present invention has at least the following advantages: 1. The recessed part of the triangular structure of this utility model and the bearing cooperate to form a high-precision coaxial centering structure. The recessed part of the triangular structure of the support base forms a precise positioning groove, which provides uniform lateral support for the sharp corner of the dust collector. When there is a slight deviation, it will be pulled back to the center position by the side wall of the recessed part of the side wall, improving the coaxial centering accuracy. Combined with the rolling support of the bearing, it reduces the amount of wear and ensures the smooth rotation of the air supply ring. The two bearings with the figure-eight structure further restrict the radial swing of the air supply ring.

[0014] 2. Through the cooperation of motor, gear, rack, support base and bearing, the air supply will be driven to reciprocate around the axis of the large circular machine in a circumferential direction, so as to greatly increase the dust removal range of the air pipe.

[0015] 3. Two segmented retaining rings are locked in a ring shape by fastening screws and tightly installed on the central cylinder of the circular knitting machine. The support column provides auxiliary support and enhances the overall structural rigidity. The two-segment splicing design of the retaining rings, secured to the central cylinder of the circular knitting machine, is compatible with various models of circular knitting machines without occupying internal space or affecting the normal weaving process. The retaining rings are coaxial with the air conveying ring, ensuring uniform meshing clearance between the air conveying ring rack and gear, avoiding lateral forces caused by meshing deviations, and further reducing the swaying of the air conveying ring.

[0029] See Figures 1-9This embodiment provides a mid-section dust removal system for a double-sided circular mill, including an annular air conveying ring 2. The air conveying ring 2 has an internal airflow channel, and its outer wall has an air inlet 12 and three evenly spaced air pipes 3. The air inlet 12 communicates with the airflow channel, and the air pipes 3 also communicate with the airflow channel. The air conveying ring 2 has a rack mounting groove 4, and a rack 5 is mounted at the bottom of the rack mounting groove 4. The rack 5 is locked to the rack mounting groove 4 with screws, enabling a detachable connection of the rack. The gas supply ring 2 includes two semi-circular ring structures: a first gas supply segment 20 and a second gas supply segment 21. Both the first and second gas supply segments 20 and 21 have two parallel airflow channels, namely airflow channel 22 and airflow channel 23. The ends of the first and second gas supply segments 20 and 21 are respectively configured as interlocking slots 200 and blocks 210. The bottom of the slot 200 has a first vent hole 201, and four screw holes 202 are located outside the first vent hole 201. The inner side of the block 210 has a second vent hole 211. The first and second vent holes 201 are positioned correspondingly. A sealing groove 212 is provided on the outer edge of the second vent hole 211, and a sealing ring is provided within the sealing groove 212. Four screw holes 213 corresponding to the screw holes 202 are provided on the outside of the sealing groove 212. During installation, the ends of the first airflow channel 22 and the second airflow channel 23 are blocked with sealing plugs. The locking block 210 of the second airflow section 21 is correspondingly locked in the locking groove 200 of the first airflow section 20, and the locking screw 13 passes through the screw holes 213 and is threaded into the screw hole 202, thus splicing the first airflow section 20 and the second airflow section 21 to form a circular airflow ring 2. The first vent 201 and the second vent 211 are connected and connected. The sealing ring prevents gas from leaking from the connection between the first vent 201 and the second vent 211.

[0030] A retaining ring 7 is located in the middle of the gas supply ring 2. The retaining ring 7 is coaxial with the gas supply ring 2. The retaining ring 7 includes two retaining ring segments: a first retaining ring segment 70 with a semi-circular ring structure and a second retaining ring segment 71. The two segments are detachably connected by screws. Specifically, as shown... Figure 8 and Figure 9 As shown, each end of the first retaining ring segment 20 is provided with a groove 73, and each end of the second retaining ring segment 21 is provided with a corresponding through hole 72. A fastening screw 74 passes through the hole at the bottom of the groove 73 and is threaded into the through hole 72, thereby locking the two retaining ring segments into a circular retaining ring 7. Multiple support pillars 8 are evenly spaced at the bottom of the retaining ring 7.

[0031] The retaining ring 7 is detachably mounted with multiple evenly spaced connecting rods 11, and a support base 6 is detachably mounted at the end of each connecting rod 11. Specifically, the retaining ring 7 has three retaining ring mounting holes 75, into which the connecting rods 11 are inserted. The bottom of the retaining ring 7 has a threaded hole, and a locking screw 76 is threadedly connected thereto. The end of the locking screw 76 enters the retaining ring mounting hole 75 and tightly abuts against the outer surface of the connecting rod 11, thus fixing the connecting rod 11. The bottom of the support base 6 has a support base mounting hole 66, into which the other end of the connecting rod 11 is inserted. The side wall of the support base 6 has a threaded hole, into which a locking screw 62 is threadedly connected. The end of the locking screw 62 enters the support base mounting hole 66 and tightly abuts against the outer surface of the end of the connecting rod 11, thus fixing the connecting rod 11.

[0032] The support base 6 has triangular protrusions 60 on both sides of its top, and a triangular recess 61 between the two protrusions 60. An inclined through hole 63 is provided through the side wall of the two protrusions 60, and the two through holes 63 form a figure-eight structure. The cross-section of the through hole 63 is square. A bearing fixing hole 67 is provided at the top of the through hole 63 and extends to the bottom of the through hole. A bearing 64 is provided inside the square structure of the through hole 63. The bearing 64 is fixedly connected to the inner ring of the bearing 64 by a set screw 65 threadedly connected to the bearing fixing hole 67 and the inner ring of the bearing 64. The two bearings 64 form a figure-eight structure.

[0033] The outer ring of the bearing 64 protrudes from the surface of the recess 61. The inner cross-section of the air supply ring 2 is triangular, and the outer cross-section is trapezoidal, making the bottom of the air supply ring 2 a pointed structure 24. The outer surface is a vertical plane structure. The bottom of the air supply ring 2 is movably disposed in the recess 61. The outer rings of the two bearings 64 contact the two side walls of the pointed structure of the air supply ring 2, so that the air supply ring 2 is slidably disposed in the recess 61. A motor fixing plate 10 is fixedly installed on the side wall of one of the support seats 6 by screws. The motor fixing plate 10 is equipped with a motor 1. The motor shaft of the motor 1 is vertically upward and is fixed with a gear 9. The gear 9 meshes with the rack 5.

[0034] The air supply ring is provided with an insertion hole 14, which communicates with airflow channel 1 22 and airflow channel 23. The end of the air pipe 3 is threadedly connected to the insertion hole 14, and a nut 15 is threadedly connected to the end of the air pipe 3 outside the insertion hole 14. The nut 15 abuts against the outer wall of the air supply ring 2. The end of the air pipe 3 is provided with an air hole communicating with airflow channel 1 22 and airflow channel 23.

[0035] In practical implementation, the two retaining rings are segmented and locked into a ring shape by fastening screws 74, and then tightly installed on the central cylinder of the circular knitting machine. The support column 8 plays an auxiliary supporting role, improving the overall structural rigidity of the installation. By retaining the retaining rings 7 on the central cylinder of the circular knitting machine, it can be adapted to various models of circular knitting machines without occupying the internal space of the machine, and does not affect the normal spinning process of the machine after installation.

[0036] Airflow enters the airflow channel 23 of the second air delivery section 21 from the air inlet 12, exits from the air pipe 3 on the second air delivery section 21, then flows through the vent 211 at the end of the second air delivery section 21, flows to the vent 201 of the first air delivery section 20, and enters the airflow channel 22 of the first air delivery section 20, exiting from the air pipe 3 on the first air delivery section 20. The airflow exiting from the air pipe 3 removes dust from the large circular machine. During the dust removal process of the air pipe 3, the cooperation of the motor 1, gear 9, rack 5, support base 6, and bearing 64 drives the air delivery ring 2 to reciprocate around the axis of the large circular machine, thereby greatly increasing the dust removal range of the air pipe 3. The motor 1 works, driving the gear 9 to rotate, and through the meshing relationship between the gear and the rack, driving the air delivery ring 2 to rotate. The air delivery ring 2 slides and rotates in the recessed part at the top of the support base 6.

[0037] The triangular recess 61 forms a precise positioning groove that limits the bottom sharp corner of the air supply ring 2, preventing it from shifting horizontally. The outer ring of the bearing 64 contacts the side wall of the air supply ring 2, converting sliding friction into rolling friction, significantly reducing wear, while ensuring the smooth rotation of the air supply ring 2. The ends of the air supply channels 1 22 and 23 of the air supply segment are blocked with sealing plugs and connected only through the precisely matched vent holes 1 201 and 2 211, preventing air leakage at non-interface points.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
