Description

Technical Field

[0001] The invention belongs to the field of textile technology, and in particular relates to a yarn guide control system based on a double-sided knitting machine. Background Art

[0002] As a textile tool, jacquard machine generally refers to the mechanism on the loom that controls the pattern. The yarn guide device of the double-sided knitting jacquard machine is an important component on the textile machine. It is mainly used to realize the transmission of spinning fabrics. In the existing jacquard machine, the spinning fabric is generally guided by the yarn guide roller.

[0003] In the prior art, the working mode of the yarn guide roller in the jacquard machine is mainly to convey the spinning fabric forward by attaching it to its surface, and to guide the spinning fabric during the conveying process. Although this method of guiding the fabric by relying solely on the yarn guide roller can be used for fabric guidance, it is easy to cause the fabric to deviate on the yarn guide roller during the conveying process, and the fabric will be separated from the yarn guide roller, which will affect the normal operation of the entire jacquard machine and ultimately reduce the production efficiency of the jacquard machine. To this end, we provide a yarn guide control system based on a double-sided knitting machine to solve the above problems. Summary of the invention

[0014] The present invention has the following beneficial effects:

[0015] In the present invention, when external air enters the negative pressure guide cavity along the air inlet and is discharged into the air guide mechanism along the air outlet, a negative pressure environment is generated at the position of the strip negative pressure hole in the process, so that the textile gauze conveyed forward along the surface of the horizontal yarn guide seat generates downward suction under the action of negative pressure, which can effectively prevent the textile gauze from deviating or falling off on the surface of the horizontal yarn guide seat during the conveying process, thereby improving the quality of guiding and conveying the textile gauze.

[0016] During the process of guiding and conveying textile gauze according to the present invention, the air suction device in operation draws out the air on the inner side of the inner supporting tube through the air suction duct. During this process, the external air enters the negative pressure guide cavity along the air inlet and is discharged into the first air guide duct along the air outlet, and then enters the inner supporting tube through the second air guide duct and is discharged into the exhaust channel through the air suction duct and the exhaust duct in sequence, and is finally discharged from the opening at the bottom of the exhaust channel. During the process of drawing out the air on the inner side of the inner supporting tube, the air in each conical yarn guide portion and the hollow guide portion is also drawn out, and a negative pressure environment is generated near the negative pressure notch on the conical yarn guide portion at the axial opening, thereby causing the textile gauze to slide along the surface of the conical yarn guide portion.

[0017] When the present invention conveys the textile gauze forward along the surface of the horizontal yarn guide seat, the fourth pulley is driven to move towards the motor seat by the positioning motor. In the process, the second transmission belt is used to generate downward pressure on the fifth pulley, so that the yarn guide positioning part on the lifting cylinder gradually moves downward and the second elastic part is stretched. When the yarn guide positioning part is engaged with the inside of the curved yarn guide groove below it, the lifting seat just slides downward along the guide rod and rests on the limit plate. Subsequently, in the process of controlling the forward conveying of the textile gauze, the yarn guide positioning part scrapes the upper surface of the textile gauze to achieve dust cleaning on the upper surface of the textile gauze, and at the same time, the dust cleaning on the lower surface of the textile gauze is achieved under the action of the continuously rotating conical yarn guide parts, thereby achieving the cleaning of the surface of the textile gauze while achieving the guidance of the textile gauze.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Slot 111; when external air enters the negative pressure guide cavity 102 along the air inlet 106 and is discharged to the inside of the air guide mechanism 2 along the air outlet 110, a negative pressure environment will be generated at the position of the strip negative pressure hole 109 in this process, so that the textile gauze conveyed forward along the surface of the horizontal yarn guide seat 101 will generate downward suction under the action of negative pressure (making the textile gauze move closely against the surface of the horizontal yarn guide seat 101 to prevent the textile gauze from detaching from the horizontal yarn guide seat 101 during the guided conveying process), which can effectively prevent the textile gauze from deviating on the surface of the horizontal yarn guide seat 101 during the conveying process, thereby improving the quality of the guided conveying of the textile gauze.

[0041] In this embodiment of the present invention, the flow assembly 5 includes a hollow flow tube 501 rotatably fitted between the curved groove 103 and the arc-shaped closed cover 105, an inner support tube 502 coaxially arranged inside the hollow flow tube 501, an annular mounting groove 503 is provided on the circumferential side of the hollow flow tube 501 close to the side of the exhaust control mechanism 4, an outer radial opening 504 corresponding to the negative pressure yarn guide assembly 6 is arranged in an annular array on the circumferential side of the hollow flow tube 501, and an inner radial opening 505 corresponding to the outer radial opening 504 is arranged in an annular array on the circumferential side of the inner support tube 502;

[0042] The negative pressure yarn guide assembly 6 includes a conical yarn guide portion 601 which is fitted inside the corresponding outer radial opening 504, and a hollow guide portion 602 which is connected to its inner cavity is fixedly arranged on one side of the conical yarn guide portion 601, and the hollow guide portion 602 is slidably fitted inside the corresponding inner radial opening 505. The conical yarn guide portion 601 is connected to the inner support tube 502 by a first elastic member 603, and a negative pressure notch 604 is provided at the curved end of the conical yarn guide portion 601. When a negative pressure yarn guide assembly 6 rotates to the axial opening 104, the conical yarn guide portion 601 on the negative pressure yarn guide assembly 6 at the position of the axial opening 104 extends upward to the outside of the axial opening 104 under the action of the elastic restoring force of the first elastic member 603. In this process, the negative pressure environment at the negative pressure notch 604 causes the textile yarn to slide along the surface of the conical yarn guide portion 601 without rotating to the axial opening 1 The curved end of the conical yarn guide portion 601 on each negative pressure yarn guide assembly 6 at 04 is retracted inside the outer radial opening 504, and under the elastic force of the first elastic member 603 in the compressed state, the curved end of the conical yarn guide portion 601 on each negative pressure yarn guide assembly 6 is fitted on the arc-shaped sealing cover 105 and the inner wall of the curved groove 103.

During this process, external air enters the negative pressure guide cavity 102 along the air inlet 106 and is discharged into the first air guide duct 201 along the air outlet 110, and then enters the inner support tube 502 through the second air guide duct 202 and passes through the exhaust duct 404 and the exhaust duct 405 in sequence to be discharged into the exhaust channel 402, and finally is discharged from the opening at the bottom of the exhaust channel 402. In the process of extracting the air inside the inner support tube 502, the air in each conical yarn guide portion 601 and the hollow guide portion 602 is also extracted, and a negative pressure environment is generated near the negative pressure notch 604 on the conical yarn guide portion 601 at the axial opening 104, thereby causing the textile gauze to slide along the surface of the conical yarn guide portion 601.

[0045] Specific embodiment 2, on the basis of specific embodiment 1, the transmission assembly further includes a first support shaft 406 and a second support shaft 407 rotatably arranged on the corresponding mounting frame 107, a first pulley 408 is fixedly arranged on the peripheral side of the first support shaft 406, a wind-driven impeller 401 is arranged inside the exhaust channel 402 and fixedly connected to the first support shaft 406, a transmission gear 409 is fixedly arranged at the end of the first support shaft 406 relative to the wind-driven impeller 401, and a transmission gear ring 410 meshing with the transmission gear 409 is fixedly arranged inside the annular mounting groove 503;

[0046] The second support shaft 407 is respectively fixedly provided with a second pulley 411 and a third pulley 412 on the side surface thereof. The first pulley 408 is connected to the second pulley 411 via a first transmission belt 413. With this structural design, the air discharged into the exhaust channel 402 through the exhaust pipe 404 and the exhaust pipe 405 in sequence is discharged through the opening at the bottom of the exhaust channel 402. In this process, the air-driven impeller 401 is driven to rotate by the discharged air flow. The first support shaft 406 which rotates synchronously with the air-driven impeller 401 drives the first pulley 408 to rotate synchronously. 3 and the second pulley 411 drive the second support shaft 407 to rotate synchronously, and the transmission gear 409 that rotates synchronously with the first support shaft 406 drives the transmission gear ring 410 to rotate synchronously, thereby realizing the continuous rotation of the entire second yarn guiding mechanism 3, a moving frame 414 is slidably provided at the bottom of the horizontal yarn guiding seat 101, and a fourth pulley 415 is rotatably provided on one side of the moving frame 414, and a positioning motor 417 is installed on the motor seat 416 fixedly provided at the bottom of the horizontal yarn guiding seat 101, and an adjusting screw 418 that is threadedly matched with the moving frame 414 is connected to the output end of the positioning motor 417.

[0047] In this embodiment of the present invention, a yarn guiding positioning mechanism 7 is arranged between the two mounting frames 107; wherein the yarn guiding positioning mechanism 7 comprises a lifting seat 701 slidably arranged inside the vertical slideway 108, a transverse bearing rod 702 is fixedly arranged on one side of the lifting seat 701, a lifting cylinder 703 is fixedly arranged between the two transverse bearing rods 702, and a yarn guiding positioning portion 704 adapted to the curved surface yarn guiding groove 111 is fixedly arranged at the bottom of the lifting cylinder 703; a fifth pulley 705 rotatably connected to the corresponding transverse bearing rod 702 is arranged directly above the third pulley 412, and the third pulley 412, the fourth pulley 415 and the fifth pulley 705 are connected by a second transmission belt 419. When the control adjustment motor 417 is rotated, the rotation of the adjustment screw 418 can control the moving frame 414 to move towards the motor seat 416. In this process, the movement of the fourth pulley 415 drives the second transmission belt 419 to change its shape, and then the second transmission belt 419 The downward pressure on the fifth pulley 705 causes the yarn guide positioning portion 704 on the entire lifting cylinder 703 to move downward until the yarn guide positioning portion 704 is engaged with the curved yarn guide groove 111 below it. At this time, the textile yarn attached to the surface of the horizontal yarn guide seat 101 is confined in the curved yarn guide groove 111, thereby further avoiding the textile yarn from being offset or separated from the horizontal yarn guide seat 101 during the guiding and conveying process, thereby greatly improving the stability of the guided conveying of the textile yarn. A guide rod 706 that slidably cooperates with the corresponding lifting seat 701 is fixedly arranged inside the vertical slide 108, and a limiting disk 707 is fixedly arranged on the side surface of the guide rod 706. A first connecting plate 708 is fixedly arranged on the side of the lifting seat 701 relative to the transverse load-bearing rod 702, and a second connecting plate 709 fixed to the inner side of the corresponding mounting frame 107 is arranged above the first connecting plate 708, and the first connecting plate 708 and the second connecting plate 709 are connected by a second elastic member 710.

[0048] When the textile yarn is conveyed forward along the surface of the horizontal yarn guide seat 101, the fourth pulley 415 is driven by the positioning motor 417 to move towards the motor seat 416. In the process, the second transmission belt 419 is used to generate downward pressure on the fifth pulley 705, so that the yarn guide positioning part 704 on the lifting cylinder 703 gradually moves downward and the second elastic member 710 is stretched. When the yarn guide positioning part 704 is engaged with the inside of the curved yarn guide groove 111 below it, the lifting seat 701 just slides downward along the guide rod 706 and rests on the limit plate 707. Then, in the process of controlling the forward conveying of the textile yarn, the yarn guide positioning part 704 is used to scrape the upper surface of the textile yarn to achieve dust cleaning on the upper surface of the textile yarn. At the same time, under the action of the continuously rotating conical yarn guide parts 601, the dust cleaning on the lower surface of the textile yarn is achieved, thereby achieving the cleaning of the surface of the textile yarn while achieving the guidance of the textile yarn.
