Description

Winding spinning system and yarn monitoring method for open-jet spinning process

Technical field

The present invention relates to the technical field of air-jet spinning technology, and in particular to a winding spinning system and a yarn monitoring method used in the air-jet spinning technology.

Background technique

Air-jet spinning is a new spinning technology that uses airflow to condense and twist fibers in a high-speed rotating spinning cup and output them into yarn. It does not use spindles, but mainly relies on multiple components such as opening rollers, spinning rotors, and false twisting devices. The opening roller is used to grab and comb the fed sliver fibers. The centrifugal force generated by its high-speed rotation can throw out the captured fibers. The spinning cup is a small metal cup. Its rotation speed is more than 10 times higher than that of the detangling roller. The resulting centrifugal effect discharges the air in the cup outward; based on the principle of fluid pressure, the cotton fibers enter the airflow cup. , and form a fiber flow, which continuously moves along the inner wall of the cup.

According to Chinese patent CN 113122976 B, a ring spinning machine yarn overlapping system and method and a yarn processing tool are disclosed for auxiliary wiring when the yarn is broken at the spinning station of the ring spinning machine.

These flying flowers, Impurities such as dust and lint will accumulate on the spinning machine and the yarn, seriously affecting the quality of spinning. Workers need to clean the flying particles, dust and lint on the spinning machine from time to time. When there are particles attached to the yarn Flying will reduce the smoothness of the yarn when it is rolled up, affecting the appearance of the fabric and affecting the quality of the cotton yarn.

Embodiment 3

The present invention also provides a yarn monitoring method for the air-jet spinning process. Using the above-mentioned winding spinning system for the air-jet spinning process, the operation method includes the following steps:

S1: By winding the yarn 2 on the surface of the winding roller 3, and installing sensors and cameras on the spinning winding machine 1;

S2: Drive the winding roller 3 to rotate and wind the yarn 2, and turn on the sensor and camera to start working;

S3 monitors the breakage, tightness, tightness, winding density and other parameters of yarn 2 in real time.

In step 1, specifically, the yarn 2 is contacted at the bottom of the adjusting device 4, and the yarn 2 is passed through the collection assembly 5, and wound on the surface of the winding roller 3; and in step 2, specifically, the yarn 2 is wound around the After the winding roller 3 is mounted, the winding roller 3 is driven to rotate for winding, and the sensor and camera are turned on for monitoring; and step 3 specifically controls the winding speed of the winding roller 3 through the data fed back by the sensor and camera. .

During operation, the yarn 2 is contacted at the bottom of the tension roller 403 so that the tension roller 403 rests on the surface of the yarn 2. The weight of the tension roller 403 presses on the yarn 2 so that the yarn 2 falls downwards and is in a tightened state. And pass the yarn 2 through the inner wall of the blocking block 504 and then wrap it around the winding roller 3, and then drive the winding roller 3 to wind up. When the yarn 2 is transported, the tension roller 403 is loosened because the influence of gravity will A chute 401 falls down, pressing the yarn 2 to tighten the yarn 2. When the yarn 2 is conveyed too tightly, the tension roller 403 will be lifted upward along the first chute 401, so that the yarn 2 is at a suitable tightness. position, so that the tension roller 403 can pre-adjust the yarn 2 to be wound to the appropriate tension according to the tightness of the yarn 2 conveying.

When the staff discovers through the monitoring of cameras and sensors that the tension roller 403 moves according to the tightness of the yarn 2, they press the pressing block 410 downward with their hands to drive the rotating rod 409 to rotate and compress the torsion spring 411. While the pressing block 410 rotates The limit rod 412 is driven to slide out of the limit groove 413 and the limit groove 413 is released. At this time, the staff holds the handle 801 with the other hand and slides it up and down according to the tightness of the yarn 2 so that the yarn 2 is in a tight position. At the right position, after adjusting the precision wheel 406, align the limit rod 412 with the limit groove 413, and then release the hand pressing the pressing block 410. At this time, the torsion spring 411 resumes its deformation and drives the rotating rod 409 to rotate so that the pressing block 410 Return to the original position so that the limit rod 412 is inserted into the limit groove 413, thereby realizing the adjustment of the precision wheel 406.

When the winding roller 3 is winding, it pulls the yarn 2 so that the yarn 2 pulls the moving member 502 to slide back and forth along the inner wall of the first sliding groove 501. At the same time, the outer wall of the yarn 2 comes into contact with the blocking block 504, and the blocking block 504 The gaps between them will collect flying particles, dust and lint on the surface of the yarn 2, thereby collecting and cleaning the surface of the yarn 2.

When the blocking block 504 needs to be replaced to clean the attached flying flowers, close the spinning winding machine 1 and the winding roller 3, press the blocking block 605 with your hand to compress the spring 604 and retract the blocking block 605 into the second sliding groove 603 Unlock the blocking block 502 from the card slot 602, and then push the blocking block 504 out of the third chute 601 by hand, thereby disassembling the blocking block 504 and cleaning it. After the blocking block 504 is cleaned, press the blocking block 605 with your hand to The spring 604 compresses and causes the blocking block 605 to retract into the second sliding groove 603, and then pushes the blocking block 504 into the third sliding groove 601. When the blocking block 605 contacts the inner wall of the third sliding groove 601, the blocking block 605 is moved by the third sliding groove. The inner wall of 601 resists and continues to push the blocking block 504. When the blocking block 504 slides to the position of the slot 602, the spring 604 resumes its deformation and pushes the blocking block 605 out of the second sliding slot 603 and engages with the slot 602, thereby realizing replacement of the collection block. Block 504 and clean it before installing it. After the blocking block 504 is installed, pass the yarn 2 through the blocking block 504 and wind it to the winding roller 3, and drive the spinning winding machine 1 and the winding roller 3. Turn.
