Description
Technical Field
[0001] This utility model relates to the field of yarn twist testing technology, and specifically to a yarn twist testing device. Background Technology
[0002] Twist refers to the number of turns per inch of yarn, which determines the strength of the yarn. Yarn twist testing generally falls into two categories: direct counting and untwisting / twisting. The direct counting method involves clamping both ends of a sample of a certain length under specified tension, rotating one end of the sample to remove the twist, and measuring the number of twists when the sample's constituent units are parallel. The number of twists removed is the number of twists for that length of yarn sample. Current direct counting methods use hand-cranked yarn twist meters. However, after untwisting the roving, the original length of roving becomes a loose, multi-strand yarn. The operator then uses a needle to separate the individual strands, requiring a count. During this count, the overlapping and interlocking positions of the strands in the loose state create a chaotic and inconvenient counting process. Furthermore, manually counting the strands can easily introduce errors.
[0003] In the prior art, during the yarn separation process, a certain length of yarn will become loose, so that the yarn is not in a taut state during rotation, which makes it easy for the yarn to become tangled and knotted during rotation. Therefore, this device provides a yarn twist test device. Utility Model Content

[0012] As a further improvement to the above solution, a threaded rod is threadedly installed on the top of the yarn clamping frame, a control handle is fixedly installed on the top of the threaded rod, and a lower pressure plate is rotatably installed on the bottom of the threaded rod.

[0034] Furthermore, the guide rod 21 can limit and guide the sliding frame 19, so that the lead screw 17 can only drive the sliding frame 19 to slide after rotation.
[0035] In a further preferred embodiment of the present invention, a control rod is provided on the top of the sliding clamping plate 16, and the control rod 20 is in contact with the control groove.
[0036] Furthermore, the control groove allows the control lever 20 to move and drive the sliding clamping plate 16 to bear force, thereby allowing the sliding clamping plate 16 to slide and clamp the yarn after being subjected to force.

The lower pressure plate 24 is slidably installed on the inner wall of one side of the yarn clamping frame 3.
[0038] Furthermore, the control handle 23 drives the threaded rod 22 to rotate. The threaded rod 22 can drive the lower pressure plate 24 to descend through the threaded engagement. After descending, the lower pressure plate 24 can press down and fix the other end of the yarn. The twist test box 1 drives the rotating shaft 2 and the clamped yarn to rotate. The twist can be measured by calculating the number of rotations through the twist test box 1.
[0039] The specific operation is as follows: Adjust the position of the sliding seat 5 according to the required yarn length. After adjustment, lock the sliding seat 5 in place using the fixing bolt 13, and fix both ends of the yarn above the yarn clamping frame 3 and the sliding clamping plate 16 respectively. At this time, the operator can control the second knob 18 to rotate the lead screw 17. The lead screw 17, through threaded engagement, drives the sliding frame 19 and the control rod 20 to move. After movement, the control rod 20 can control the sliding clamping plate 16, thereby enabling the sliding clamping plate 16 to control the yarn. The yarn is clamped and fixed, and the control handle 23 drives the threaded rod 22 to rotate. The threaded rod 22 drives the lower pressure plate 24 to descend through the threaded engagement. After descending, the lower pressure plate 24 can press down and fix the other end of the yarn. The twist test box 1 drives the rotating shaft 2 and the clamped yarn to rotate. The twist can be measured by calculating the number of rotations of the twist test box 1. During the measurement process, the weight 12 of the connecting rope 11 can limit the clamping box 8, allowing the clamping box 8 to move, so that the yarn can be kept taut.
