Description

Technical Field

[0001] The invention relates to the technical field of color spun yarn quality detection, and in particular to a color spun yarn dyeing quality detection device and a detection method. Background Art

[0002] Mélange yarn is a type of yarn that can achieve a hazy three-dimensional effect and texture that cannot be achieved by white dyeing. Mélange yarn is pollution-free to use and can also control color difference to the greatest extent.

[0003] Colored yarns will be sampled and tested before leaving the factory to test their color fastness. Color fastness tests mainly focus on washing fastness, rubbing fastness and light fastness. These tests can evaluate the yarn's ability to retain color in daily use and ensure that the color is not easy to fade or transfer, thereby protecting consumers' interests and enhancing the market competitiveness of products.

[0004] However, the existing color fastness test of spun yarn has the following problems: 1. Each color fastness test is mostly carried out with a separate instrument. Multiple instruments will not only take up space in the factory, but also cause the tested yarn to be damaged during the transfer process, resulting in errors in the test results. 2. In the process of color fastness testing of colored yarn, sampling testing is mostly carried out, and the colored yarn is straightened for testing. When the tail end of the colored yarn lacks tension, the straightened colored yarn will become soft, which will cause the colored yarn to detach from the testing equipment, resulting in the inability to detect the colored yarn on the machine; 3. After the color fastness test of colored spun yarn, the tested colored spun yarn is usually stored for backup. The workers usually wind the yarn on the winding roller during storage, which increases the labor cost of the factory. At the same time, after workers wind the yarn for a long time, their hands are easily cut by the yarn, causing injuries to the workers. Summary of the invention

The rotation of the rotating frame will drive the clamping plate to rotate, so that the clamping plate slightly clamps the yarn; S3: Put the iron column at the top of the yarn into the groove at the top of the positioning frame. At this time, the distance between the two support frames is smaller than the diameter of the yarn, which will prevent the yarn from falling between the two support frames, thereby supporting the yarn; S4: straighten the top part of the yarn and clamp the yarn with a clamp to limit the length of the top of the yarn, put the rest of the yarn into the washing drum, and start the first servo motor; S5: The first servo motor drives the stirring frame to rotate, so as to wash the yarn. After a period of time, the first servo motor is stopped, and the first stepper motor is started when the aqueous solution in the washing drum stops rotating. S6: The first stepper motor drives the rotating rod and the end of the yarn to rotate synchronously. During the rotation of the rotating rod, the clamping plate on the rotating rod squeezes the pressing wheel and the moving frame to slide in the slide slot synchronously, and squeezes the first spring to shrink and deform. At the same time, the yarn falls on the wire wheel; S7: When the clamping plate is out of contact with the pressure wheel, the first spring that has been squeezed and deformed recovers, pushing the pressure wheel and the moving frame to move toward the wire wheel to squeeze water from the yarn; S8: When the first fixed module contacts the second fixed module, the second fixed module first fixes the front end of the yarn, then releases the fixation of the yarn by the first fixed module, and starts the linear motor, so that the linear motor drives the slide, the second fixed module and the yarn to move to the left synchronously; S9: When the second fixed module moves to the left, the yarn will be dried by the activated hot air blower, and the dried yarn will be compared with the color card to confirm the washing fastness of the yarn; S10: When the linear motor moves to the leftmost end, the cylinder is started, and the cylinder drives the second fixed module and the yarn to move upward. When the second fixed module passes over the first friction block, the hydraulic cylinder is started, and the hydraulic cylinder pushes the first friction block to move toward the second friction block, so that the first friction block and the second friction block clamp the yarn, and then the friction color fastness test of the yarn is performed; S11: When the second fixed module moves to the top, the linear motor is started again to move the linear motor to the right, so that the second fixed module moves synchronously with the top of the yarn toward the take-up module; S12: When the second fixed module moves to the rightmost end at the top, the second stepper motor is started, and the second stepper motor drives the second fixed module and the yarn to rotate; S13: During the rotation of the second fixed module, the iron column is attracted by the first arc-shaped magnetic strip and moves along the arc of the first arc-shaped magnetic strip. When the second stepper motor rotates a certain angle, the iron column is separated from the first arc-shaped magnetic strip and falls into the positioning port under the dual action of gravity and the second arc-shaped magnetic strip, thereby fixing one end of the yarn to the take-up roller. S14: After the yarn and the take-up roller are fixed, the second servo motor is started, and the second servo motor drives the first pulley and the second pulley to rotate, thereby driving the take-up roller to rotate, thereby completing the winding of the yarn; S15: When the tail end of the yarn is out of contact with the pressure wheel, the iron column at the tail will fall to the right side of the block, and the yarn will pass through the gap between the two blocks. When the yarn is wound up, the yarn will pull the carriage to move; S16: When the carriage moves to the leftmost end, the yarn and the block are in a horizontal state, so that the yarn has a downward pulling force under the action of the iron column, so that the yarn is straightened and will not fall off the moving device easily; S17: After winding is completed, the take-up roller is directly pulled out to disengage the take-up roller from the plug-in column. During the process of pulling out the take-up roller, the arc-shaped groove squeezes the slide column to slide into the avoidance hole, so that the slide column and the arc-shaped groove are disengaged. Otherwise, the take-up roller is fixed; S18: After replacing the new take-up roller, the linear motor will move to the far left, and then the cylinder will be retracted. After retracting to the bottom, the linear motor will move to the far right; S19: When the linear motor moves to the right, the linear motor pushes the protrusion at one end of the slide, driving the slide to reset and be fixed by the linear magnetic strip; S20: Reverse the first stepper motor to reset the first fixed module, thus completing a yarn quality inspection.

[0031] In order to collect the yarn 23 after detection, the wire collection module in the present invention includes a second servo motor, which is fixed to one side of the frame 1 by bolts, and the output shaft of the second servo motor passes through the frame 1 and is keyed to the first pulley 10, one side of the frame 1 is rotatably connected to the second pulley 12, and the first pulley 10 and the second pulley 12 are driven by a belt, one side of the second pulley 12 is keyed to a connecting shaft 45, one end of the connecting shaft 45 is welded with a plug post 47, a wire collection roller 46 is plugged into the outer wall around the plug post 47, a baffle 7 is provided on one side of the wire collection roller 46, and a avoidance hole 50 is opened on the top of the plug post 47, and the avoidance hole 50 A third spring 49 is provided on the inner wall at the bottom, a sliding column 48 is welded on the top of the third spring 49, an arc-shaped groove 51 is provided on the top inner wall of the slot into which the plug 47 is inserted on one side of the take-up roller 46, and the plug 47 is inserted into the arc-shaped groove 51, a positioning opening 53 is provided on the top of the take-up roller 46, and an adjustment module for assisting the front end iron column 22 to enter the positioning opening 53 is provided on one side of the frame 1. When the second fixed module brings the yarn 23 to the take-up module, the second servo motor is started, and the second servo motor drives the first pulley 10 to rotate, so that the second pulley 12 rotates together with the connecting shaft 45, the plug 47 and the take-up roller 46 to take up the wire.

[0032] In order to make the yarn 23 better wound up by the take-up roller 46, the adjustment module in the present invention includes a placement frame 44, which is fixed to one side of the frame body 1 by bolts, and two first arc-shaped magnetic strips 43 are bonded to the bottom of the placement frame 44, and a second arc-shaped magnetic strip 52 is bonded to the arc surface of the positioning port 53. When the second stepper motor is started, the second stepper motor will drive the second fixed module to rotate. During the rotation of the second fixed module, the iron column 22 will be adsorbed by the first arc-shaped magnetic strip 43 and move along the arc of the first arc-shaped magnetic strip 43. When the second stepper motor rotates a certain angle, the iron column 22 will be separated from the first arc-shaped magnetic strip 43, and under the dual action of gravity and the second arc-shaped magnetic strip 52, it will fall into the positioning port 53, thereby fixing one end of the yarn 23 to the take-up roller 46.

[0033] In order to make the tail of the yarn 23 have tension, the wire pulling module in the present invention includes a guide groove 41, the guide groove 41 is opened on one side of the frame 1, and a slide 3 is slidably connected in the guide groove 41. Two blocks 54 are fixed to the top of one end of the slide 3 by bolts, and the distance between the two blocks 54 is greater than the diameter of the yarn 23. A protrusion 56 is provided at the other end of the slide 3. The protrusion 56 is a soft material with a certain deformation ability, preferably elastic rubber. A linear magnetic strip 55 is bonded to one side of the slide 3, and the linear magnetic strip 55 can absorb the liquid guide frame 4, so as to limit the position of the slide 3. The slide 3 will not change its position easily. When the tail end of the yarn 23 is out of contact with the pressure wheel 59, the iron column 22 at the tail will fall to the right side of the block 54, and the yarn 23 will pass through the gap between the two blocks 54. When the yarn 23 is wound, the yarn 23 will pull the slide 3 to move. When the slide 3 moves to the leftmost end, the yarn 23 and the block 54 are in a horizontal state, so that the yarn 23 has a downward pulling force under the action of the iron column 22, so that the yarn 23 is straightened. When the linear motor 17 is reset, the linear motor 17 will push the protrusion 56 at one end of the slide 3 to drive the slide 3 to reset.

[0034] A method for using a color spinning yarn dyeing quality detection device: S1: Add detergent and water in proportion into the washing drum 5 to form a washing solution, and tie both ends of the yarn 23 to be tested to the iron posts 22; S2: Start the electric push rod 18, which drives the connecting frame 19 to move, thereby pulling the pull rod 20 to move, and then drives the rotating frame 21 to rotate. The rotation of the rotating frame 21 drives the clamping plate 27 to rotate, so that the clamping plate 27 slightly clamps the yarn 23; S3: Put the iron column 22 at the top of the yarn into the groove at the top of the positioning frame 26. At this time, the distance between the two brackets 24 is smaller than the diameter of the yarn 23, which will prevent the yarn 23 from falling between the two brackets 24, thereby supporting the yarn 23; S4: straighten the top part of the yarn 23, and clamp the yarn 23 with the clamping plate 27, so as to limit the length of the top of the yarn 23, and put the rest of the yarn 23 into the washing drum 5, and start the first servo motor; S5: The first servo motor drives the stirring frame 58 to rotate, so as to wash the yarn 23. After a period of time, the first servo motor is stopped, and the first stepper motor is started when the aqueous solution in the washing drum 5 stops rotating. S6: The first stepper motor drives the rotating rod 6 and the end of the yarn 23 to rotate synchronously. During the rotation of the rotating rod 6, the clamping plate 27 on the rotating rod 6 squeezes the pressing wheel 59 and slides synchronously with the moving frame 14 in the slide groove, and squeezes the first spring 15 to shrink and deform. At the same time, the yarn 23 falls on the wire wheel 28. S7: When the clamping plate 27 is out of contact with the pressing wheel 59, the first spring 15 that has been squeezed and deformed recovers, and pushes the pressing wheel 59 and the moving frame 14 to move toward the wire wheel 28 to squeeze water from the yarn 23; S8: When the first fixed module contacts the second fixed module, the second fixed module first fixes the front end of the yarn 23, then releases the fixation of the yarn 23 by the first fixed module, and starts the linear motor 17, so that the linear motor 17 drives the slide 9, the second fixed module and the yarn 23 to move synchronously to the left; S9: When the second fixed module moves to the left, the yarn 23 is dried by the activated hot air blower 2, and the dried yarn 23 is compared with the colorimetric card 37 to confirm the washing fastness of the yarn 23; S10: When the linear motor 17 moves to the leftmost end, the cylinder 32 is started, and the cylinder 32 drives the second fixed module and the yarn 23 to move upward. When the second fixed module passes over the first friction block 39, the hydraulic cylinder 36 is started, and the hydraulic cylinder 36 pushes the first friction block 39 to move toward the second friction block 40, so that the first friction block 39 and the second friction block 40 clamp the yarn 23, and then the friction color fastness test is performed on the yarn 23; S11: When the second fixed module moves to the top, the linear motor 17 is started again to move the linear motor 17 to the right, so that the second fixed module moves synchronously with the top of the yarn 23 toward the take-up module; S12: When the second fixed module moves to the rightmost end at the top, the second stepper motor is started, and the second stepper motor drives the second fixed module and the yarn 23 to rotate; S13: During the rotation of the second fixed module, the iron column 22 is attracted by the first arc-shaped magnetic strip 43 and moves along the arc of the first arc-shaped magnetic strip 43. When the second stepper motor rotates a certain angle, the iron column 22 is separated from the first arc-shaped magnetic strip 43 and falls into the positioning port 53 under the dual effects of gravity and the second arc-shaped magnetic strip 52, so that one end of the yarn 23 is fixed to the take-up roller 46. S14: After the yarn 23 and the take-up roller 46 are fixed, the second servo motor is started, and the second servo motor drives the first pulley 10 and the second pulley 12 to rotate, thereby driving the take-up roller 46 to rotate, and then completing the winding of the yarn 23; S15: When the tail end of the yarn 23 is out of contact with the pressure wheel 59, the iron column 22 at the tail will fall to the right side of the block 54, and the yarn 23 will pass through the gap between the two blocks 54. When the yarn 23 is wound, the yarn 23 will pull the carriage 3 to move; S16: When the carriage 3 moves to the leftmost end, the yarn 23 and the block 54 are in a horizontal state, so that the yarn 23 has a downward pulling force under the action of the iron column 22, so that the yarn 23 is straightened and will not fall off the moving device easily; S17: When the winding is completed, the take-up roller 46 is directly pulled out, so that the take-up roller 46 and the plug post 47 are disconnected. During the process of pulling out the take-up roller 46, the arc-shaped groove 51 will squeeze the slide post 48 to slide into the avoidance hole 50, so that the slide post 48 and the arc-shaped groove 51 are disconnected. Otherwise, the take-up roller 46 is fixed. S18: After the new take-up roller 46 is replaced, the linear motor 17 moves to the far left, and then the cylinder 32 is retracted. After retracting to the bottom, the linear motor 17 moves to the far right; S19: When the linear motor 17 moves to the right, the linear motor 17 pushes the protrusion 56 at one end of the slide 3, driving the slide 3 to reset and be fixed by the linear magnetic strip 55; S20: Reverse the first stepper motor to reset the first fixed module, and complete a quality inspection of the yarn 23.
