Description

Technical Field

[0001] The utility model relates to the technical field of yarn sampling, in particular to a yarn fineness detection fixed-length sampler. Background Art

[0002] The fineness of the yarn is called the yarn count. The yarn used for fabrics can be thick or thin, and the thickness is usually expressed in count. The higher the count, the thinner the yarn, and the lower the count, the thicker the yarn. When testing the yarn fineness, it is necessary to take fixed-length samples and then weigh the fixed-length sampled yarn on a balance to determine the yarn fineness.

[0003] After searching, the existing Chinese patent with publication number CN202220385499.2 discloses a fixed-length sampling device for detecting the fineness of textile yarn. The yarn is pressed against the clamping surface of the first clamping member by a positioning member. The first clamping member moves along the stretching direction to simulate the hand movement to stretch the yarn, thereby reducing the repetitive hand movements of the yarn sampling tester. The force used to stretch multiple yarns tends to be consistent, which helps to improve the sampling efficiency.

[0004] The above-mentioned technical scheme has the following defects: although such a fixed-length sampler for yarn fineness detection can clamp and stretch multiple groups of yarns through multiple groups of clamping surfaces, so that the tool can perform fixed-length sampling on multiple groups of stretched yarns, such a fixed-length sampler requires multiple groups of yarns for feeding, and multiple groups of yarns are manually loaded one by one, which makes the loading process more troublesome. In order to further improve the working efficiency of yarn fixed-length sampling, a fixed-length sampler for yarn fineness detection is proposed, which only requires one group of yarn for yarn loading, and can simultaneously stretch and fix the length of multiple sections of yarn, thereby effectively improving the working efficiency of yarn fixed-length sampling, thereby facilitating yarn fineness detection.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0008] The utility model solves the above-mentioned technical problems as follows: a fixed-length sampler for yarn fineness detection, comprising a detection platform body, a count scale and a fixed-length plate, the count scale being placed on the top of the detection platform body, a positioning frame, a sampling frame, a guide frame and a yarn feeding machine being fixedly installed on the top of the detection platform body, a positioning screw being threadedly connected to the top of the positioning frame, an upper positioning plate being rotatably connected to the bottom of the positioning screw, a No. 1 yarn guide wheel being evenly rotatably connected to the sampling frame, an adjusting frame being fixedly installed on the top of the detection platform body, a brake servo motor being fixedly installed on the inner wall of the adjusting frame, a ball screw being fixedly connected to the brake servo motor, a screw nut being threadedly connected to the outer wall of the ball screw, and the Both sides of the lead screw nut are fixedly connected with load-bearing sliders, and limit rods are fixedly installed on both sides of the inner wall of the adjusting frame near the middle position, the load-bearing slider is fixedly connected with a guide wheel placement plate, and the guide wheel placement plate is evenly fixedly installed with a connecting rod, and the connecting rod is rotatably connected with the second yarn guide wheel, and the top of the sampling frame is fixedly connected with a cylinder, and two fixed-length plates are provided, one side of the fixed-length plate is installed on the driving end of the cylinder, and the other side of the fixed-length plate is installed on the outer wall of the sampling frame, and the middle position of the fixed-length plate is slidably connected with a cutting tool, and the outer wall of the fixed-length plate near the middle position is magnetically connected with positioning magnetic strips on both sides, and the inner wall of the guide frame is rotatably connected with guide wheels on both sides near the middle position.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the upper positioning plate is slidably connected to the inner wall of the positioning frame, and the bottom of the upper positioning plate and the bottom of the inner wall of the positioning frame are evenly provided with sawtooth grooves, and the sawtooth grooves on both sides are meshed.

The sliding cutting tool can cut the positioned yarn to obtain fixed length samples. The sampled yarn can be placed in the count scale for count measurement.

[0021] 4.
