Description

Technical Field

[0001] The invention relates to the technical field of production of new material nylon yarn, in particular to a quality detection device for strength uniformity of new material nylon yarn. Background Art

[0002] The new material nylon yarn is a new type of textile material that achieves performance upgrades based on traditional polyamide fiber through component optimization, structural innovation or functional composite. The uniformity of nylon yarn is an important quality indicator. It is related to the manufacturing process of nylon yarn, the quality and properties of raw materials, and the status and parameter settings of spinning equipment. If there is unevenness in the manufacturing process of nylon yarn, such as uneven fiber distribution and uneven winding tension, it will lead to uneven strength of nylon yarn in the length direction.

[0003] In actual production, common strength quality tests usually evaluate the quality of yarn by simulating the stress state of yarn in actual use. Specifically, the yarn sample is fixed between the clamps of the stretching machine and unidirectional tension is gradually applied until it breaks. This testing method can only perform quality tests on the intercepted nylon yarn samples, and cannot perform strength tests on the entire roll of nylon yarn, nor can it obtain the strength uniformity data of the entire roll of nylon yarn. If the staff repeatedly intercepts and clamps the yarn until a roll of yarn is tested, it will undoubtedly greatly increase the manual workload and affect the testing efficiency.

[0027] The specific operation is as follows: the reel 12 loaded with the whole roll of nylon yarn to be tested is loaded into the bearing frame 11, the nylon yarn end is manually pulled out and passed through the wire hole 10 and the middle seam of the clamping rollers 1302 on both sides one by one, and the nylon yarn end is passed into the clamping ends of the opposite bottom surfaces of the clamping claws 108 on both sides, the cylinder 101 is activated and the wedge block 103 is pulled upward through the tension meter 102, and the cone surfaces on both sides of the wedge block 103 are forced to abut against the contacts on the opposite top surfaces of the clamping claws 108 on both sides, so that the clamping claws 108 on both sides rotate in opposite directions, thereby driving the clamping ends of the bottom of the clamping claws 108 on both sides to rotate and close to clamp the free end of the nylon yarn, and wait until the current nylon yarn segment is at the preset tension. After the value is detected to be compliance or broken, the cylinder 101 presses the wedge block 103 downward, and the wedge block 103 releases the abutment force applied by the cone surfaces on both sides to the clamping claws 108, so that the free end of the nylon yarn is released, and the next section of the nylon yarn segment to be tested is ready for clamping. The present application links the strength detection component 1 with the telescopic stroke of the cylinder 101, so that the cylinder 101 clamps the free end of the nylon yarn through the abutment force applied by the wedge block 103 and the clamping claws 108 on both sides during the lifting stroke, and automatically releases the free end of the nylon yarn due to the release of the force during the descending stroke of the cylinder 101, thereby performing segmented clamping and testing on the entire roll of yarn, without the need for manual repeated clamping, and improving the detection efficiency;

[0029] The specific operation is as follows: Under the pull of the cylinder 101, the mounting plate 106 slides on the guide rail 8 via the back slider 2. During the upward movement, the wedge block 103 always contacts the clamping jaws 108 on both sides and applies force to maintain a stable clamping force until the nylon yarn segment to be tested is tightened.

The bottom end of the fork arm 1303 is connected to a plastic wheel 1305, and the plastic wheel 1305 abuts against the inner step surface of the adjacent trigger rod 3. The top end of the fork arm 1303 is connected to a cutter 1306, and the cutters 1306 on the top of the fork arms 1303 on both sides cooperate to cut the fixed end of the nylon yarn.

[0031] The specific operation is as follows: during the process of the mounting plate 106 sliding down on the guide rail 8 through the back slider 2, the inner step surfaces of the trigger rods 3 on both sides of the slider 2 abut against the plastic wheels 1305 connected to the bottom ends of the fork arms 1303, and during the movement of the plastic wheels 1305 on the step surfaces of the trigger rods 3, the fork arms 1303 on both sides are forced to rotate and close, and then the fixed ends of the nylon yarns are cut off by the cutters 1306 arranged opposite to each other at the top ends of the fork arms 1303 on both sides, and the nylon yarns remaining in the seam of the clamping roller 1302 continue to be clamped by the clamping claws 108 as the thread ends of the next section of the test material for continuous strength testing experiments.

The length of each intercepted nylon yarn sample is consistent and firmly clamped, ensuring the accuracy of continuous strength detection and thus ensuring the accuracy of the strength uniformity data of the whole roll of nylon yarn.

[0032] In summary, when using the new material nylon yarn strength uniformity quality detection device:

[0033] First, the reel 12 loaded with the whole roll of nylon yarn to be tested is loaded into the bearing frame 11, the nylon yarn end is manually pulled out and passed through the wire hole 10 and the middle seam of the clamping rollers 1302 on both sides one by one, and the nylon yarn end is passed into the clamping ends of the opposite bottom surfaces of the clamping jaws 108 on both sides. The cylinder 101 is activated and the wedge block 103 is pulled upward through the tension meter 102. The conical surfaces on both sides of the wedge block 103 are in contact with the contacts on the opposite top surfaces of the clamping jaws 108 on both sides, so that the clamping jaws 108 on both sides rotate in opposite directions, thereby driving the clamping jaws 108 on both sides. The bottom clamping end 8 rotates and closes to clamp the free end of the nylon yarn. Under the pull of the cylinder 101, the mounting plate 106 slides on the guide rail 8 through the back slider 2. During the upward movement, the wedge block 103 always contacts the clamping claws 108 on both sides to maintain a stable clamping force until the nylon yarn segment to be tested is tightened. Then, the unidirectional tension is gradually increased until the test is compliant or the nylon yarn breaks. The breaking strength and elongation at break are recorded, and the tensile strength is calculated based on the fracture area to evaluate the load-bearing capacity and strength uniformity of the yarn.

[0034] Secondly, after the current nylon yarn segment is tested to be compliant or broken under the preset tension value, the cylinder 101 presses down the wedge block 103, and the wedge block 103 releases the abutment force applied by the cone surfaces on both sides to the clamping claws 108, so that the free end of the nylon yarn is released, and the next nylon yarn segment to be tested is ready for clamping. The present application links the strength detection component 1 with the telescopic stroke of the cylinder 101, so that the cylinder 101 clamps the free end of the nylon yarn through the abutment force applied by the wedge block 103 and the clamping claws 108 on both sides during the lifting stroke, and automatically releases the free end of the nylon yarn due to the release of the force during the descending stroke of the cylinder 101, thereby performing segmented clamping and testing on the entire roll of yarn, without the need for manual repeated clamping, and improving the detection efficiency;

[0035] Finally, during the process of the mounting plate 106 sliding down on the guide rail 8 through the slider 2 on the back side, the inner step surfaces of the trigger rods 3 on both sides of the slider 2 abut against the plastic wheels 1305 connected to the bottom ends of the fork arms 1303, and during the movement of the plastic wheels 1305 on the step surfaces of the trigger rods 3, the fork arms 1303 on both sides are forced to rotate and close, and then the cutters 1306 arranged at the top ends of the fork arms 1303 on both sides are used to cut off the fixed ends of the nylon yarns. The nylon yarns remaining in the seam of the clamping roller 1302 continue to be clamped by the clamping claws 108 as the thread ends of the next section of the test material for continuous strength testing experiments. This application links the descending stroke of the cylinder 101 with the linkage cutting component 13, so that the nylon yarns of the current line segment are After the strength test is completed, after the clamping claw 108 releases the free end of the nylon yarn, the trigger rod 3 abuts the plastic roller at the bottom end of the fork arm 1303, and the fixed end of the nylon yarn is cut off by the cutter 1306 set relatively at the top of the fork arms 1303 on both sides, and the wedge block 103 is pulled up again to clamp the thread end of the next section of the test material to realize the process closed loop. Only one cylinder 101 is required for the whole process, and the nylon yarn is automatically intercepted and clamped through the linkage with the strength detection component 1 and the linkage cutting component 13, so as to quickly complete the strength test of the whole roll of nylon yarn. The length of each intercepted nylon yarn sample is consistent and firmly clamped, ensuring the accuracy of continuous strength detection and thus ensuring the accuracy of the strength uniformity data of the whole roll of nylon yarn.
