Description

Technical Field

[0001] The invention belongs to the technical field of textile processing, in particular to a textile yarn toughness detection device. Background Art

[0002] Textile is a process of processing fiber materials into yarn, fabric or finished products. During the production and processing of yarn, the toughness of the yarn needs to be tested. The toughness test can reflect the resistance of the yarn when subjected to external forces, so as to timely discover quality problems in the yarn, such as insufficient fiber strength, loose yarn structure, etc., and then ensure that the yarn meets the production and use requirements.

[0003] The patent with announcement number CN219799025U discloses a textile yarn toughness testing device, and its technical highlights are: it includes a workbench, a fixed frame is fixedly installed on the surface of the workbench, two groups of relatively distributed rotating rods are rotatably installed on the opposite side walls of the fixed frame, a winding roller is fixedly installed on the surface of the rotating rod, yarn is wound between the winding rollers, one end of one group of rotating rods extends out of the fixed frame and is connected to a driving motor, the inner cavity of the fixed frame is provided with a detection rod located above the yarn, the fixed frame is provided with a control mechanism that cooperates with the detection rod, the control mechanism includes an installation assembly and a detection assembly, the installation assembly is located between the side walls of the fixed frame and is connected to the detection rod, the detection assembly includes an impact part and a lifting part, the impact part is connected to the installation assembly, and the lifting part is located in the inner cavity of the fixed frame and is connected to the impact part.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The yarn toughness is tested by using two winding rollers to wind up the yarn and impacting the yarn at the same time. When the yarn toughness is unqualified, the yarn will break, and then the break position, break shape and number of impacts are recorded to achieve toughness detection. However, usually, in order to obtain more accurate toughness data, multiple data need to be recorded. These data can be used for subsequent analysis and comparison to evaluate the overall toughness performance of the yarn. Therefore, after the yarn breaks, it is necessary to continue to wind and impact the yarn, and continue to record the break position, break shape and number of impacts. However, in the above technical solution, when the yarn breaks, the toughness detection work ends, which will result in an incomplete assessment of the toughness, and when the broken yarn is placed on the winding roller again, it still needs to be done manually. The whole process is relatively cumbersome, which increases the labor intensity of the workers.

[0045] Specifically, when the existing textile yarn toughness testing equipment is in use, it uses two winding rollers 3 to wind up the yarn, and at the same time cooperates with the method of impacting the yarn to test the toughness of the yarn. When the yarn toughness is unqualified, the yarn will break, and then the break position, break shape and impact number are recorded to achieve toughness testing. However, usually, in order to obtain more accurate toughness data, it is necessary to record multiple data, which can be used for subsequent analysis and comparison to evaluate the overall toughness performance of the yarn. Therefore, after the yarn breaks, it is necessary to continue to wind and impact the yarn, and continue to record the break position, break shape and impact number. However, in the prior art, when the yarn breaks, the toughness testing work ends, which will result in an incomplete evaluation of the toughness, and when the broken yarn is placed back on the winding roller 3, it still needs to be done manually. The whole process is relatively cumbersome, which increases the labor intensity of the workers.

[0046] The yarn is then pulled back by the two rollers 15 and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction so that the yarn can be pulled back and the two rollers 16 move in a rotational direction The limiting rings 15 move away from each other, and the yarn falls onto the winding roller 3, and then the limiting ring 15 is driven to reset to the leftmost side, and the pressing roller 19 on the right side presses the yarn onto the winding roller 3 again. At this time, the winding rollers 3 on both sides rotate simultaneously again, and the conveying effect of the yarn can be achieved again, and the toughness detection work can be carried out. By repeating the above operation repeatedly, multiple sets of data on the yarn breakage position, breakage shape and impact number can be recorded, thereby improving the comprehensiveness of the yarn toughness evaluation. At the same time, it also saves the process of manually placing the broken yarn on the winding roller 3, which is more convenient and labor-saving, and reduces the labor intensity of the workers. In addition, since the yarn is always in contact with the two arc plates 16 under the action of elastic force, the yarn can slide between the two arc plates 16 under the action of traction, and the yarn will not be separated from the limiting rings 15 when it breaks, thereby ensuring that the broken end of the yarn can be smoothly placed on the winding roller 3;

[0047] Since there is still some yarn remaining on the right winding roller 3 when the yarn breaks, after the broken end of the yarn is placed again on the right winding roller 3, the broken end of the yarn may be entangled with the remaining yarn, thereby affecting the subsequent toughness detection work. Therefore, when the yarn breaks, the winding roller 3 is driven to rotate to the angle where the pressure roller 19 is above it, and the pressure roller 19 is away from the winding roller 3, and then the electric push rod 2 33 is used to drive the mounting block 26 to move backward, so that the pushing column 27 passes through the gap between the remaining yarn and the pressure roller 19, and then the motor 5 25 drives the threaded rod 3 24 to rotate, so that the transverse rod 23 slides to the right, and the pushing column 27 can be used to peel off the yarn remaining on the winding roller 3. At this time, the yarn remaining on the winding roller 3 is The yarn hanging on the dispersing column 27 is hung on the dispersing column 27, thereby realizing the cleaning of the yarn remaining on the winding roller 3, and avoiding the situation that the broken end of the yarn and the remaining yarn are entangled with each other after the broken end of the yarn is placed again on the right winding roller 3, thereby ensuring the smooth progress of the subsequent toughness detection work. In addition, when the remaining yarn is hung on the dispersing column 27, the electric push rod 28 is used to drive the scraper ring 29 to slide on the dispersing column 27 until the scraper ring 29 moves to the end of the dispersing column 27, so that the yarn hanging on the dispersing column 27 can be pushed off, thereby realizing the cleaning of the yarn hanging on the dispersing column 27, and avoiding the situation that the dispersing column 27 and the yarn on the winding roller 3 are entangled with each other during subsequent use due to the accumulation of more yarn on the surface of the dispersing column 27, thereby affecting its stripping effect.

[0048] Working principle: one end of the yarn to be tested for toughness is placed between the left winding roller 3 and the pressure roller 19, and then the motor four 22 is used to drive the threaded rod two 21 to rotate, so that the pressure roller 19 can be moved closer to the winding roller 3 to press the yarn, and then the yarn is wound around the pressure roller 19 and the winding roller 3 to achieve the winding of the yarn, and then the other end of the yarn is placed between the pressure roller 19 and the winding roller 3 on the right, and the pressure roller 19 is also used to press it, and then the motor one 4 on both sides rotates at the same time to transport the yarn to the right, so that different positions of the yarn are aligned with the impact block 9, and then the motor two 8 is used to drive the connecting rod one 30 to rotate, and at the connecting rod two 31, the reciprocating rod 32 and the impact block 9 move back and forth up and down, so that the impact block 9 impacts the yarn, thereby realizing the toughness detection of the whole length of the yarn and improving the comprehensiveness of the detection. During the winding process of the yarn, it passes between the two limit rings 15 and fits with the two arc plates 16 under the action of the spring 18. When the yarn breaks, the two winding rollers 3 stop rotating, and the yarn loses traction and falls under the action of gravity. Then the winding roller 3 on the left is driven to rotate again, so that the broken end of the yarn approaches the limit ring 15. When the broken end of the yarn fits with the two arc plates 16, the motor three 13 is used to drive the threaded rod one 5 to rotate, so that The displacement plate 10 moves from left to right to drive the broken end of the yarn to move from left to right. At the same time, the winding roller 3 on the left continues to rotate to unwind the yarn, and drives the pressure roller 19 on the right to move away from the winding roller 3 on the right, so that a gap is generated between the two until the limiting ring 15 passes through the gap. At this time, the broken end of the yarn is between the pressure roller 19 and the winding roller 3, and then the two limiting rings 15 are driven away from each other, and the yarn falls onto the winding roller 3, and then the limiting ring 15 is driven to reset to the leftmost side, and the pressure roller 19 on the right presses the yarn on the winding roller 3 again. At this time, the winding rollers 3 on both sides rotate simultaneously again, and the yarn can be transported again. The delivery effect is achieved, and toughness detection is performed. The above operation is repeated repeatedly to record multiple sets of data on yarn breakage positions, breakage forms, and impact times, thereby improving the comprehensiveness of the yarn toughness evaluation. At the same time, the process of manually placing the broken yarn on the winding roller 3 is omitted, which is more convenient and labor-saving, and reduces the labor intensity of workers. Moreover, since the yarn is always in contact with the two arc plates 16 under the action of elastic force, the yarn can slide between the two arc plates 16 under the action of traction, and the yarn will not be separated from the limit rings 15 when it breaks, thereby ensuring that the broken end of the yarn can be smoothly placed on the winding roller 3;Since there is still some yarn remaining on the right winding roller 3 when the yarn breaks, after the broken end of the yarn is placed again on the right winding roller 3, the broken end of the yarn may be entangled with the remaining yarn, thereby affecting the subsequent toughness detection work. Therefore, when the yarn breaks, the winding roller 3 is driven to rotate to the angle where the pressure roller 19 is above it, and the pressure roller 19 is away from the winding roller 3, and then the electric push rod 2 33 is used to drive the mounting block 26 to move backward, so that the pushing column 27 passes through the gap between the remaining yarn and the pressure roller 19, and then the motor 5 25 drives the threaded rod 3 24 to rotate, so that the transverse rod 23 slides to the right, and the pushing column 27 can be used to peel off the yarn remaining on the winding roller 3. At this time, the yarn remaining on the winding roller 3 is Hanging on the spreading column 27, the yarn remaining on the winding roller 3 is cleared, and the situation that the broken end of the yarn is entangled with the remaining yarn after it is re-placed on the right winding roller 3 is avoided, and the subsequent toughness detection work is smoothly carried out. In addition, when the remaining yarn is hung on the spreading column 27, the electric push rod 28 drives the scraper ring 29 to slide on the spreading column 27 until the scraper ring 29 moves to the end of the spreading column 27, and the yarn hanging on the spreading column 27 can be pushed off, thereby realizing the removal of the yarn hanging on the spreading column 27, and avoiding the situation that the spreading column 27 and the yarn on the winding roller 3 are entangled with each other during subsequent use due to the accumulation of more yarn on the surface of the spreading column 27, which affects its stripping effect. ;
