Description

Technical Field

[0001] The invention relates to the technical field of spinning quality detection, and in particular to a spinning quality detection management method and system. Background Art

[0002] Spinning is the process of forming various fibers (such as cotton, linen, silk, wool and chemical fibers) into slivers and then drawing and twisting them into yarns through specific process methods. The spinning process is divided into two main stages: slivering and yarn formation. Spinning quality refers to the standards and requirements of the physical and chemical properties of the yarn produced during the spinning process. The quality of spinning directly affects the quality and performance of the final textile products. For example, if the hairiness is too long, the yarn will easily tangle and be broken, which will not only increase the production cost of spinning, but also affect the quality and aesthetics of the spinning products.

[0003] In order to understand the quality of each batch of yarn after spinning, the corresponding yarn will be subjected to quality management testing, which includes tensile testing and hairiness testing. However, the conventional testing method requires manual intervention throughout the process. The operator needs to switch the yarn back and forth and transfer the yarn to the corresponding testing equipment. The operation is cumbersome, the degree of automation is low, and the accuracy of the test results needs to be improved. Summary of the invention

[0019] A management method for a spinning quality detection system comprises the following steps:

[0020] Step 1: First place multiple sets of yarn rollers on the top of the quality inspection machine, then draw the yarn from the yarn rollers through the combing wheel and Z-block in turn, and clamp them in the yarn clamping head;

[0021] Step 2: The rotating cylinder drives the half gear to rotate and control the rack to move, and then controls the internal thread column to rotate and move at the same time. At this time, when the yarn hook rotates to the highest point, the servo motor drives the lead screw to rotate and control the translation of the yarn changing seat, and the thin hook can hook the yarn. As the yarn hook rotates in the opposite direction, the thin hook will clamp the yarn into the yarn clamping groove when it is at the lowest point, and the thin hook will also detach from the yarn as the internal thread column moves;

The yarn head in the yarn clamping head will be separated from the yarn clamping head due to the tension, so that the yarn on the yarn guide is in a single strand. As the yarn continues to move, the yarn will contact the yarn guide and vibrate on the yarn guide. The vibration sensor senses the vibration frequency and can detect the hairiness value of the yarn. After the hairiness value is detected, the cylinder 2 pushes the connecting column to drive the horizontal push plate to move, so that the yarn can be pushed away from the sleeve to complete the yarn withdrawal operation.

[0023] Step 4: After the yarn stops winding, the cylinder is used to push the connecting kit to clamp the yarn between the T-type sub-block and the C-type mother block. At this time, one of the yarn pulling parts is pushed down by the electric guide rail, and the tension sensor can monitor the tension data in real time until the yarn is broken, and the online collection of the yarn tension data can be completed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The spinning quality inspection and management method and system of the present invention switches the type of yarn through the yarn changing mechanism, and the yarn hooking mechanism can automatically transfer the yarn to the yarn winding and withdrawing mechanism, which solves the trouble of manual threading and realizes the automatic winding of the yarn. In addition, with the cooperation of the yarn pulling mechanism and the hairiness component, the tension data and hairiness value of the yarn can be detected online, and various data of the yarn are automatically collected, which saves manpower and improves the accuracy of the inspection results.

[0026] 2. The spinning quality inspection management method and system of the present invention drives the half gear to rotate and control the movement of the rack through a rotating cylinder, and can control the internal threaded column to rotate and move at the same time. On this basis, the servo motor drives the screw rod to rotate and control the translation of the yarn changing seat, which can facilitate the thin hook to hook the yarn into the yarn clamping groove. The thin hook will also detach from the yarn as the internal threaded column moves. The design is reasonable, and automatic hooking of the yarn is realized, which provides convenience for subsequent quality inspection.

[0027] 3. The spinning quality inspection and management method and system of the present invention realizes automatic winding of the yarn by driving the driving gear to rotate and controlling the rotation of the yarn winding member through servo motor 2. The yarn can vibrate on the yarn guide plate, and the vibration sensor senses the vibration frequency to measure the yarn hairiness value.

As the yarn hooking member 48 rotates in the opposite direction, the fine hook 482 will clamp the yarn into the yarn clamping groove 713 when it is at the lowest point, and the fine hook 482 will also be separated from the yarn as the internal threaded column 46 moves;

[0058] Step 3: The servo motor 2 75 drives the driving gear 73 to rotate and control the yarn winding member 71 to rotate, and the yarn clamped in the yarn clamping groove 713 is continuously wound on the sleeve 711. The yarn head in the yarn clamping head 35 is pulled away from the yarn clamping head 35, so that the yarn on the yarn guide piece 62 is in a single state. As the yarn continues to move, the yarn will contact the yarn guide piece 62 and vibrate on the yarn guide piece 62. The vibration sensor 63 senses the vibration frequency and can detect the yarn hairiness value. After the hairiness value is detected, the cylinder 2 761 pushes the connecting column 762 to drive the horizontal push plate 763 to move, so that the yarn can be pushed away from the sleeve 711, and the yarn withdrawal operation is completed;

[0059] Step 4: After the yarn stops winding, the cylinder 51 is used to push the connecting kit 52 to clamp the yarn between the T-shaped sub-block 533 and the C-shaped mother block 532. At this time, one of the yarn pulling parts 53 is pushed downward by the electric guide rail 54, and the tension sensor 55 can monitor the tension data in real time until the yarn is broken, thereby completing the online collection of the yarn tension data.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
