Technical Field

[0002] The scientific name of the circular knitting machine is the circular weft knitting machine, or the circular weft knitting machine. Because the circular knitting machine has many loop forming systems, which are called yarn feeding paths or loop forming paths in enterprises, or paths for short, it has high speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability, so it has developed rapidly. The circular knitting machine is mainly used to weave clothing and decorative fabrics, and can also weave general industrial fabrics.

[0003] Nowadays, during the knitting process of the circular knitting machine, the tension of the yarn changes all the time due to the transportation of the yarn and the weaving of the knitting needles. There is a bending angle in the transportation direction of the bottom yarn and the surface yarn before and after entering the bottom yarn hole and the surface yarn hole. The change in tension can easily cause the bottom yarn and the surface yarn to break, affecting the knitting quality of the circular knitting machine. For this reason, a wire guiding mechanism is generally required to be installed inside the current knitting circular knitting machine to achieve stable wire guiding activity.

[0004] The existing application number is CN202111659684.2, which is a circular knitting machine with an adaptive yarn feeding function, comprising a circular knitting machine frame, a yarn feeding frame, an adjustment component and a weaving mechanism, wherein the adjustment component is installed on the top plate of the circular knitting machine frame; the yarn feeding frame is fixedly connected to the upper end of the adjustment rod of the adjustment seat, and the weaving mechanism is arranged on the base at the lower end of the circular knitting machine frame, wherein a plurality of yarn feeding guide mechanisms are arranged in a ring along the axis in the weaving mechanism, and the yarn feeding guide mechanism comprises a base plate, a first guide adjustment component and a second guide adjustment component, and the second guide adjustment component is located at one end of the base plate close to the outer periphery of the weaving mechanism.

[0005] In the above-mentioned existing device, the tightness of the yarn frame and the yarn is adaptively adjusted by setting an adjustment component and a plurality of yarn feeding guide mechanisms, so that the weaving uniformity of the large circular machine is improved. However, when performing the tension adjustment transmission of the yarn, the adaptive adjustability of the yarn inlet and outlet ends is poor, and it is difficult to change with the yarn tension adjustment state. At the same time, during the yarn guiding process, dust or lint is more likely to adhere to the outside, and during the tension adjustment guiding process, the cleanliness of the yarn outside is low.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention is provided with an adaptive wire guiding device, that is, the yarn can pass through the wire guiding piece arranged on the left side of the upper end of the wire guiding shell, and then pass through the tensioning wire guiding assembly arranged in the middle part of the wire guiding shell, and finally pass through the wire guiding piece arranged on the right side of the lower end of the wire guiding shell, so as to complete the docking of the yarn and the adaptive wire guiding device. In conjunction with the tensioning wire guiding assembly, the yarn tension can be adaptively adjusted through the detection of the tension sensor during the yarn guiding process, and the wire guiding pieces on both sides can not only realize the auxiliary pressing of the yarn inlet and outlet ends, but also adaptively adjust the angle with the yarn tension adjustment to achieve stable yarn guiding cooperation. At the same time, in conjunction with the dust removal structure arranged on the front side of the tensioning wire guiding assembly, it can also assist in realizing wind dust removal of the yarn, thereby achieving adaptive adjustment of the tension in the yarn guiding process and efficient dust removal.

[0019] The setting of the wire guide, that is, the pressure wheel arranged inside the wire guide cylinder can cooperate with the damper and compression spring connected on one side to press the yarn inlet or outlet end, and the receiving plate arranged on one side of the pressure wheel can cooperate with the elastic telescopic rod arranged on one side to achieve stable compression of the yarn and ensure the stability of the wire guide.

[0020] The arrangement of the wire guide drum, the rotating shaft and the clockwork spring is such that when the yarn is tensioned and adjusted and is pulled, the pulled yarn will realize the synchronous pulling of the wire guide drum. In this way, the wire guide drum can cooperate with the rotating shafts arranged on both sides of the outer end to realize the adaptive adjustment of the wire guide angle, and during the subsequent resetting, the rebound assistance of the clockwork spring can achieve automatic resetting.

[0021] The arrangement of the turntable, transmission plate, guide wheel and impact wheel, that is, the yarn can be passed between the guide wheel and the impact wheel respectively installed on the left and right sides of the transmission plate to achieve a stable structure of the wire guiding state. When the wire guiding tension needs to be adjusted, the detection control signal of the tension sensor can be used to drive the servo motor to make the servo motor realize the rotation of the turntable. In this way, the transmission plate can drive the guide wheels and impact wheels on both sides to realize the tensioning of the yarn, stabilize the yarn guiding, and maintain the appropriate wire guiding tightness.

[0022] The setting of the transmission plate, that is, the transmission motor arranged inside the connecting seat, can realize the rotation of the main gear connected to the front end. As the main gear rotates, the first sub-gear and the second sub-gear connected to the left and right sides of the main gear will rotate at the same time. Therefore, the connecting shafts respectively installed on the outside of the first sub-gear and the second sub-gear will move with the rotation to connect with the vertical groove opened on one side of the connecting rod to realize the reciprocating push and pull of the connecting rod, so that the connecting rod drives the impact wheel connected to one side to perform the impact rolling and flattening activity of the yarn, thereby reducing the problem of yarn bending.

[0023] The setting of the impact wheel, that is, the slider can be driven back and forth by the connecting rod to realize the reciprocating movement of the impact wheel body, so that the impact wheel can perform impact, rolling and leveling activities on the yarn in the direction of the guide wheel, and the spring elastic assist connected to the limit blocks set on the upper and lower sides of the docking ring can make the impact wheel body move again and eliminate the self-swaying phenomenon, so as to further improve the impact, rolling and leveling effect, and achieve a certain impact force buffer, thereby avoiding excessive impact damage to the yarn.

[0024] The setting of the dust removal structure, that is, the fan can generate wind force to blow the yarn entering the dust removal shell, so that the dust attached to the outside of the yarn is blown off, and the dust is filtered in cooperation with the filter.

[0025] The setting of the roller frame and the wire guide ring, that is, the roller frame arranged at the lower left end and the upper right end of the dust removal shell, can make the yarn pass smoothly into the interior of the dust removal shell and stably connect with the middle part of the wire guide ring, and realize subsequent dust removal coordination without changing the yarn guiding speed.

[0026] The setting of the oscillation structure, that is, when the transmission motor realizes the rotation of the main gear, the rotation of the cam will be realized synchronously, and as the cam rotates, the abutment plate at the bottom will be pushed down to move the abutment plate down to the docking rod. In this way, the wire guide ring installed at the upper end of the docking rod will pull down the yarn. At the same time, the first oscillation spring and the second oscillation spring at the bottom and the outer side of the lower end of the docking rod will respectively realize compression and stretching activities. When the cam completes the downward pressing activity of the abutment plate, the first oscillation spring and the second oscillation spring will elastically restore to make the docking rod move the wire guide ring up and down reciprocatingly. In this way, the wire guide ring can drive the yarn to oscillate back and forth, so that the yarn can be shaken off the attached dust through the oscillation effect, and cooperate with the wind dust removal effect to further improve the yarn dust removal quality and efficiency.

[0042] Specifically, when in use, the yarn can be placed inside the wire guide housing 51 and connected to the wire guide pieces 52 provided on the left upper end and the right lower end of the wire guide housing 51 to achieve compression of the yarn inlet and outlet positions. At the same time, the yarn will enter the tensioning wire guide assembly 55 provided at the middle end of the wire guide housing 51, and cooperate with the tension sensor 53 provided on the upper and lower sides of the wire guide housing 51 to achieve real-time detection of the tightness of the yarn during the wire guiding process. When a problem with the tightness of the yarn is detected, a control signal will be generated to the servo motor 54 provided on the rear side of the wire guide housing 51, so that the servo motor 54 can realize the rotation of the tensioning wire guide assembly 55 connected to the front side, so as to achieve tension adjustment during the yarn guiding process and ensure the stability of the subsequent weaving process.

[0043] See also Figure 4-6 The wire guide member 52 in this embodiment includes a wire guide cylinder 521 on the left side of the upper end or the right side of the lower end of the vertical wire guide housing 51, a rotating shaft 522 installed on both sides of the outer end of the wire guide cylinder 521 and rotatably connected to the inner side of the wire guide housing 51, and a clockwork spring 523 connected to the outer ends of the rotating shaft 522 on both sides and arranged inside the wire guide housing 51. Therefore, through the cooperation of the rotating shaft 522 and the clockwork spring 523, the wire guiding direction of the wire guide cylinder 521 can be adaptively adjusted when the yarn tension is adjusted. A wire pressing structure 524 installed inside the wire guide cylinder 521 can realize adaptive adjustment of the tension at the inlet and outlet ends.

[0046] Specifically, when the yarn is passed into the wire guide housing 51, the wire guide cylinder 521 provided on the left side of the upper end and the right side of the lower end of the wire guide housing 51 can be connected with the yarn inlet and outlet ends respectively, and when entering the wire guide cylinder 521, the yarn can be clamped between the pressure wheel 5245 and the receiving plate 5246, so that the pressure wheel 5245 can press the yarn under the elastic extrusion cooperation of the damper 5242 and the compression spring 5243 provided inside the connecting shell 5241, so that the yarn is stably contacted with the outer side of the receiving plate 5246. At the same time, the elastic telescopic rod 5248 provided on the upper and lower right sides of the receiving plate 5246 can improve the pressing effect of the receiving plate 5246 on the yarn. In this way, when the pressure wheel 5245 and the receiving plate 5246 are pressed against each other, the state of the yarn inlet and outlet ends can be guaranteed. The invention relates to a method for adjusting the tension of the yarn and the yarn guide shell 51 to prevent the yarn from being loose and turning.

[0047] When the yarn tension is reduced, the rotating shaft 522 cooperates with the spring spring 523 connected to the outer end of the rotating shaft 522 to achieve the rebound effect of the spring spring 523 to achieve the rotation and reset of the wire guide cylinder 521, making the adaptive adjustment of the overall angle of the wire guide cylinder 521 flexible and reliable.

[0048] See also Figure 7-9The tensioning wire guide assembly 55 in this embodiment includes a turntable 551 installed on the rear side of the wire guide housing 51 and connected to the front output end of the servo motor 54, a transmission plate 552 installed on the front side of the turntable 551 that can realize reciprocating impact drive, guide wheels 553 rotatably connected to the left and right sides of the front end of the transmission plate 552 for assisting in wire guiding and tension adjustment, impact wheels 554 connected to the left and right sides of the front end of the transmission plate 552, and the impact wheel 554 and the guide wheel 553 are arranged opposite to each other on the left and right sides, and a dust removal structure 555 installed in the middle of the front side of the transmission plate 552 can realize wind dust removal for the yarn performing the wire guiding activity.

[0049] The transmission plate 552 includes a connection seat 5521 connected to the middle of the front side of the rotating disk 551, a plate body 5522 installed on the front side of the connection seat 5521, a transmission motor 5523 installed inside the connection seat 5521, a main gear 5524 installed in the middle of the plate body 5522 and connected to the front side of the transmission motor 5523, a first sub-gear 5525 and a second sub-gear 5526 meshingly connected to the left and right sides of the main gear 5524, and the first sub-gear 5525 In line with the rotation direction of the second sub-gear 5526, a connecting shaft 5527 is respectively arranged on one side of the front end of the first sub-gear 5525 and the second sub-gear 5526, and a connecting rod 5528 is connected to the outer side of the connecting shaft 5527 and plugged into the inside of the plate body 5522. The connecting rod 5528 is arranged in an inverted T-shaped rod as a whole, and a vertical groove is integrally formed at the connecting end of the connecting rod 5528 and the connecting shaft 5527, and one side of the connecting rod 5528 is connected to the impact wheel 554.

[0050] Among them, the impact wheel 554 includes a slider 5541 which is slidably embedded in the side of the plate body 5522 and connected to the side of the connecting rod 5528 away from the connecting shaft 5527, a docking ring 5542 built into the slider 5541 for locking the docking and slightly moving left and right, a limit block 5543 fixedly connected to the upper and lower sides of the docking ring 5542 and inserted into the upper and lower sides of the slider 5541, a spring 5544 connected to the upper and lower end sides of the limit block 5543, and the spring 5544 is arranged in pairs along each side of the limit block 5543, so that the elastic force of the spring 5544 can be cooperated to achieve an elastic impact effect, an impact wheel body 5545 arranged on the front side of the docking ring 5542, and a lock shaft 5546 correspondingly inserted into the inside of the impact wheel body 5545 and connected to the inside of the docking ring 5542.

[0051] Among them, the limit blocks 5543 arranged at the upper and lower ends of the docking ring 5542 are respectively slidably docked with the upper and lower inner parts of the slider 5541, and the docking ring 5542 is integrally provided with an internal thread to ensure that the docking ring 5542 can be threadedly locked with the locking shaft 5546 to ensure that the impact wheel body 5545 is in a stable installation and rotation state.

[0052] Specifically, when the yarn is connected to the tensioning wire guide assembly 55, it needs to first pass through the upper end of the left impact wheel 554, then pass through the upper end of the left guide wheel 553, then pass through the upper end of the right guide wheel 553, then pass through the lower end of the right impact wheel 554, and finally pass through the wire guide piece 52 provided on the right side of the lower end, and enter the bottom box 1 along the wire guide piece 52 provided on the right side of the lower end to perform weaving activities to complete the docking of the yarn and the tensioning wire guide assembly 55. When the yarn guiding activities are performed, the impact wheels 554 and the guide wheels 553 provided on the left and right sides respectively cooperate in transmission, which can ensure the smoothness of the yarn guiding process;

[0053] When the yarn tension adjustment activity is to be achieved, the monitoring control signal of the tension sensor 53 can be used to achieve the operation of the servo motor 54 on the rear side of the guide wire housing 51. When the servo motor 54 rotates, the turntable 551 connected to the front side of the servo motor 54 will realize the rotation activity, that is, when the turntable 551 rotates clockwise, it will synchronously drive the connecting seat 5521 connected to the front side, so that the connecting seat 5521 can achieve the synchronous clockwise rotation of the front end connected plate body 5522. In this way, the guide wheel 553 and the impact wheel 554 on the left and right sides of the plate body 5522 will follow the clockwise rotation effect to realize the overall pulling of the yarn to achieve the tension of the yarn. At the same time, in the process of pulling and tightening the yarn, the yarn will realize the pulling of the guide wire member 52 connected to the inlet position and the outlet position, so that it can perform adaptive angle adjustment activities.

[0054] When the turntable 551 realizes the counterclockwise rotation of the plate body 5522, the guide wheels 553 and the impact wheels 554 on both sides will gradually release the pulling effect on the yarn, reducing the yarn tension, thereby achieving adaptive adjustment of the tension during the yarn guiding process, and flexibly responding to various yarn guiding weaving situations.

[0055] Secondly, when the impact wheel 554 is performing the yarn guiding activity, in order to reduce the bending problem of the yarn outside during the yarn guiding process, the transmission motor 5523 provided inside the connecting seat 5521 can be driven to enable the transmission motor 5523 to realize the rotation of the main gear 5524 connected to the front end. As the main gear 5524 rotates, the first sub-gear 5525 and the second sub-gear 5526 engaged on both sides of the main gear 5524 will rotate at the same time, so that the connecting shaft 5527 connected to the outside of the first sub-gear 5525 and the second sub-gear 5526 will move with the rotation to transmit to the vertical groove opened on one side of the connecting rod 5528, so as to achieve the lateral reciprocating push and pull of the connecting rod 5528, and as the connecting rod 5528 moves back and forth, the slider connected to one side of the connecting rod 5528 5541 will move back and forth along the inside of the side of the plate body 5522, so that the impact wheel body 5545 connected to the docking ring 5542 provided inside the plate body 5522 will perform impact rolling activity on the yarn toward the middle of the guide wheel 553 to roll the outside of the yarn, so that the yarn is flat and the bending problem is reduced. At the same time, during the reciprocating impact rolling process of the impact wheel body 5545, the spring 5544 connected to the limit blocks 5543 provided on the upper and lower sides of the docking ring 5542 can achieve elastic cooperation to make the impact wheel body 5545 shake left and right during the reciprocating drive of the slider 5541, so as to improve the impact rolling effect of the impact wheel body 5545 on the yarn. At the same time, the setting of the spring 5544 can achieve a certain impact force dissipation to avoid the problem of excessive impact force.

[0056] When the impact wheel body 5545 needs to be replaced, the thread locking effect can be released by rotating the lock shaft 5546 that is threadedly connected to the middle part of the docking ring 5542. In this way, the impact wheel body 5545 can be removed from the front side of the docking ring 5542 to achieve convenient replacement.

[0057] See also Figure 10-11 The dust removal structure 555 in this embodiment includes a fan 5551 installed at the upper end of the front side of the rotating disk 551, a connecting pipe 5552 connected to the lower end of the fan 5551, a dust removal shell 5553 installed at the front side of the plate body 5522 and connected to the bottom of the connecting pipe 5552, and the left and right opening ends of the dust removal shell 5553 are opposite to the guide wheel 553, and an exhaust hood 5553 installed at the upper end of the dust removal shell 5553 and connected to the bottom of the connecting pipe 5552. 54, roller frames 5555 installed at the lower left end and the upper right end of the dust removal shell 5553, through the guiding cooperation of the roller frames 5555 on both sides, the yarn can be in a stable wire guiding and dust removal process, a filter screen 5556 for dust filtering is arranged at the lower end of the dust removal shell 5553, an exhaust port 5557 is opened at the bottom of the dust removal shell 5553, and an oscillation structure 5558 installed at the middle end of the dust removal shell 5553 can assist in realizing yarn oscillation and auxiliary dust removal.

[0058] The oscillation structure 5558 includes a cam 55581 arranged inside the dust removal shell 5553 and connected to the front side of the transmission motor 5523, and the cam 55581 is relatively arranged on the front side of the main gear 5524, which can realize simultaneous rotation activities, abutting against the lower end of the cam 55581, a docking rod 55583 vertically docked at the middle part of the abutting plate 55582, a guide wire ring 55584 installed at the upper end of the docking rod 55583 for anti-wear oscillation guide wire, a support tube 55585 docked at the lower end of the docking rod 55583, and a support tube 55585 installed at the lower end of the support tube 55585 and connected to the docking rod 55583. The first oscillation spring 55586 abuts against the bottom of the connecting rod 55583, and the second oscillation spring 55587 is arranged on the outer side of the lower end of the connecting rod 55583, so that the wire guide ring 55584 can realize the reciprocating oscillation of the internal transmission yarn through the reciprocating elastic oscillation of the first oscillation spring 55586 and the second oscillation spring 55587, so as to shake off the attached dust or hair. The limiting vertical rods 55588 are symmetrically and vertically inserted on the left and right sides of the support plate 55582 and connected to the left and right sides of the support tube 55585, so as to ensure the smooth and stable up and down movement of the support plate 55582.

[0059] Among them, the center of the wire guide ring 55584 is set in a smooth convex shape, and the center position of the wire guide ring 55584 is level with the wire guide positions of the roller racks 5555 on both sides, ensuring efficient combination of the wire guide ring 55584 and the roller racks 5555 on both sides, realizing smooth and stable yarn guiding process.

[0060] Specifically, during the docking process between the yarn and the tensioning guide wire assembly 55, the middle section of the yarn will penetrate into the dust removal structure 555, and during the penetration process, it will respectively connect with the roller frame 5555 provided at the lower left end and the upper right end of the dust removal shell 5553, and at the same time, it will connect with the guide wire ring 55584 provided at the upper end of the oscillation structure 5558. In this way, the yarn can be in a straight wire guiding state and a stable preparation activity can be achieved for subsequent dust removal activities.

[0061] When performing dust removal, the fan 5551 provided at the upper end of the front side of the turntable 551 can be driven to generate wind force, and the wind blowing dust removal of the yarn can be realized through the connection pipe 5552 and the transmission of the exhaust hood 5554, so that the dust attached to the outside of the yarn can be blown off by the wind force and fall to the middle part of the lower end of the dust removal shell 5553 to connect with the filter screen 5556 provided at the middle part of the lower end of the dust removal shell 5553, and the filtered air is discharged along the exhaust port 5557;

[0062] Secondly, the cam 55581 provided inside the oscillation structure 5558 can realize synchronous rotation activity during the process of the main gear 5524 driven by the transmission motor 5523 to rotate, so that the rotating cam 55581 will realize the downward push of the bottom contact plate 55582, and in the process of the contact plate 55582 moving downward, the middle contact docking rod 55583 will be synchronously moved downward, so that the wire guide ring 55584 docked at the upper end of the docking rod 55583 will realize the downward pull of the middle part of the yarn, and in the process of the docking rod 55583 moving downward, the first oscillation spring 55586 provided inside the support tube 55585 will be squeezed, and the second oscillation spring 55587 provided on the outer side of the lower end of the docking rod 55583 will be stretched, so that the cam 55581 can realize the downward push of the bottom contact plate 55582, and in the process of the docking plate 55582 moving downward, the middle contact docking rod 55583 will be synchronously moved downward, so that the wire guide ring 55584 docked at the upper end of the docking rod 55583 will realize the downward pull of the middle part of the yarn, and in the process of the docking rod 55583 moving downward, the first oscillation spring 55586 provided inside the support tube 55585 will be squeezed, and the second oscillation spring 55587 provided on the outer side of the lower end of the docking rod 55583 will be stretched, so that When 5581 completes the downward pushing activity of the abutment plate 55582 and resets, the first oscillation spring 55586 and the second oscillation spring 55587 that are squeezed and stretched will rebound quickly, causing the docking rod 55583 to move back and forth up and down. In this way, the wire guide ring 55584 docked at the upper end of the docking rod 55583 will move synchronously to drive the yarn to achieve reciprocating oscillation, so that the dust attached to the outside of the yarn is subjected to oscillation dust removal activity, and the wind dust removal effect is combined to achieve a significant improvement in the cleaning effect of dust or lint attached to the outside of the yarn. At the same time, in the process of the up and down movement of the abutment plate 55582, the limit vertical rods 55588 connected on both sides of the support tube 55585 can be used to achieve mobile support and limit coordination to ensure the stability of the up and down movement process.
