Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, and in particular to a yarn evenness tester. Background Technology

[0002] Spinning plays a crucial role in textile engineering, as the quality of the yarn directly affects the smooth operation of subsequent processes and the appearance of the finished product. A key indicator for evaluating yarn quality is yarn evenness. Yarn evenness refers to the degree of uniformity in thickness along the length of the yarn, generally characterized by the change in yarn mass per unit length (linear density). Theoretically, yarns of the same count should have uniform thickness, but during the spinning process, factors such as operation, equipment, and technology can cause unevenness. To ensure the smooth operation of subsequent processes and product quality, yarn evenness testing is necessary. In recent years, evenness testers and their accompanying computer expert systems for spectral analysis have become increasingly widely used in actual production. Various testing instruments based on spectral analysis, such as mechanical, capacitive, and photoelectric types, have now been systematically developed. However, existing yarn evenness testers lack a yarn winding mechanism, resulting in scattered and messy yarn after testing, and causing waste. Utility Model Content

[0003] The purpose of this invention is to provide a yarn evenness tester that can recycle yarn through a winding component, thereby avoiding yarn scattering and messiness, and allowing the yarn to be reused, thus avoiding yarn waste.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A yarn evenness tester includes a frame, on which a material guiding component, a testing component, a traction component, and a winding component are provided;

[0006] The winding assembly includes multiple guide rollers located below the traction assembly, a liftable tension roller, and a winding roller.

[0007] The yarn to be tested passes sequentially through the guide assembly, testing assembly, and traction assembly, and is then wound up by the take-up assembly, thus organizing the tested yarn. The testing assembly is used to test the uniformity of the yarn, the traction assembly is used to pull the yarn, the guide wheel is used to guide the tested yarn, and the tension wheel can tension the tested yarn and can also be coordinated with the winding speed of the take-up wheel. The take-up assembly solves the problem of scattered and messy yarn on the ground, and the rewound yarn can be reused, reducing yarn waste.

[0008] The present invention is further configured such that: the tensioning wheel is rotatably connected to the lifting bracket, the lifting bracket is slidably connected to the vertical guide rail, and the vertical guide rail is fixed to the frame;

[0009] Limit blocks are fixed at both ends of the vertical guide rail, and a proximity sensor is fixed on each limit block. The proximity sensor is electrically connected to the controller, which is installed inside the frame.

[0010] The take-up reel is inserted into the motor shaft of the take-up motor, and the take-up motor is electrically connected to the controller and fixed on the frame.

[0011] The yarn passes under the tensioning wheel. When the yarn tension is high, the tensioning wheel moves upward, causing the lifting bracket to move upward. When the upper proximity sensor detects the lifting bracket, it sends a signal to the controller, which then controls the winding motor to reduce its winding speed. When the yarn tension decreases, the tensioning wheel automatically moves downward under its own weight and the weight of the lifting bracket. When the lower proximity sensor detects the lifting bracket, it sends a signal to the controller, which then controls the winding motor to increase its winding speed.

[0012] The present invention is further configured such that: a damping sleeve is provided between the motor shaft and the winding wheel, and the damping sleeve covers and is fixed on the motor shaft;

[0013] The damping sleeve is a rubber sleeve.

[0014] The damping sleeve has a certain deformation capacity, which makes it easy for the winding wheel to be inserted into the motor shaft. At the same time, the friction of the damping sleeve can drive the motor shaft to rotate the winding wheel.

[0015] The present invention is further configured such that: the test component includes an adjustment base, on which multiple capacitor blocks are fixed in parallel, with a gap between two adjacent capacitor blocks; the size of the gap can be of various specifications;

[0016] The adjustment seat is slidably connected to the adjustment compartment of the frame.

[0017] Multiple capacitor blocks with different spacing specifications can be used to adapt to yarns of different thicknesses. By moving the adjustment seat in the adjustment chamber, the corresponding capacitor block can be moved to the corresponding position for testing, which facilitates testing of yarns of different thicknesses.

[0018] The present invention is further configured such that: a damping shell is covered on the outer wall of the adjusting seat, and the outer wall of the damping shell is attached to the inner wall of the adjusting chamber;

[0019] A push-pull handle is fixed to one end of the adjustment seat.

[0020] The adjustment seat can be easily moved or fixed in any position by the friction between the damping shell and the adjustment chamber.

[0021] The present invention is further configured such that: the material guiding assembly includes multiple damping rods fixed on the frame and a main guide wheel rotatably connected to the frame; the yarn being tested can pass around the multiple damping rods to increase the resistance of yarn feeding, thereby giving the yarn passing through the testing assembly a certain tension, which can make the test more accurate.

[0022] The traction assembly includes a drive rubber wheel and a follower rubber wheel; the drive rubber wheel is equipped with a motor that drives it to rotate, the follower rubber wheel is rotatably connected to a follower seat, the follower seat is slidably connected to the frame, the follower seat is equipped with an elastic support, and the elastic support drives the follower seat to move closer to the drive rubber wheel.

[0023] The test assembly is located between the main guide wheel and the drive rubber wheel. The right ends of the main guide wheel and the drive rubber wheel are tangent to the same vertical plane, which allows the yarn ends between the main guide wheel and the drive rubber wheel to be in a vertical state, facilitating the test assembly's testing.

[0024] The outstanding effect of this utility model is:

[0025] Compared with existing technologies, the yarn can be recycled through the winding assembly, which can avoid the yarn from scattering and becoming messy. At the same time, the yarn can be reused, avoiding yarn waste.

[0026] By setting multiple capacitor blocks with various gap specifications, it can be adapted to yarns of different specifications. Attached Figure Description
