Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yarn hairiness detection, in particular to a novel yarn hairiness detection device for a warping machine. Background Art
[0002] Hairiness is the fiber ends protruding from the yarn surface. They have a direct impact on the yarn's appearance, style, weaving efficiency, and dyeing effect. Hairiness is categorized into end hairiness, loop hairiness, and floating hairiness based on the yarn's cross-sectional morphology. Excessive hairiness not only affects the yarn's appearance but also reduces the fabric's smoothness and uniformity, thereby affecting the quality of the final product. Therefore, hairiness detection and control is a crucial part of the textile industry.
[0003] Currently, hairiness detection on warping machines is mainly performed through lasers, using a laser and a receiver. When hairiness is present, the protruding fibers block the laser beam emitted by the laser transmitter and cause a change in brightness. The laser receiver then senses the abnormal laser beam and detects the hairiness on the yarn.
[0004] However, the applicant found that due to the different thicknesses of yarns, the laser and receiver cannot be adjusted in height, resulting in a fixed height of the laser beam. As a result, the laser beam cannot be aimed exactly at the middle of the yarn, which makes it easy for partially extended hairiness to go undetected during hairiness detection. To this end, we proposed a new yarn hairiness detection device for warping machines. Utility Model Content
[0005] The purpose of the utility model is to provide a novel yarn hairiness detection device for a warping machine to solve the problems raised in the above background technology.

[0011] As a preferred solution of the novel yarn hairiness detection device for warping machines described in the utility model, the sides of the mounting rods on both sides that are away from each other are in contact with the inner walls of both sides of the support frame respectively.

[0014] As a preferred solution of the novel yarn hairiness detection device for a warping machine described in the utility model, the support frame is provided with a guide sleeve for the push rod to pass through laterally.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. By rotating the hand wheel, the screw drives the connecting frame to rise and fall, and the connecting rod drives the mounting rods on both sides to rise and fall synchronously, so as to accurately adjust the height of the laser transmitter and laser receiver, so that the emitted laser beam is exactly aimed at the middle of the yarn to avoid failing to detect the outer hairiness of yarns of different thicknesses;

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] As mentioned in the background technology, in the prior art, due to the varying yarn thicknesses, the laser and receiver cannot be adjusted in height, resulting in a fixed laser beam height. This, in turn, prevents the laser beam from being precisely aligned with the center of the yarn, making it easy for partially protruding hairiness to go undetected during hairiness detection. The present utility model provides a novel yarn hairiness detection device for a warping machine.
[0023] Example 1
[0024] Reference Figures 1 to 2 A novel yarn hairiness detection device for a warping machine includes a support frame 1, wherein both sides of the inner wall of the support frame 1 are provided with guide rollers 2 for yarn guidance;
[0025] The left and right sides of the inner wall at the bottom of the support frame 1 are vertically penetrated by mounting rods 3. A laser transmitter 4 is provided on the right mounting rod 3, and a laser receiver 5 is provided on the left mounting rod 3.
[0026] A lifting assembly is provided on the left side of the top of the support frame 1. The lifting assembly is connected to the left mounting rod 3 and can drive the left mounting rod 3 to move up and down;
[0027] A connecting rod 10 is connected between the mounting rods 3 on both sides. The connecting rod 10 is located below the support frame 1, so that the mounting rods 3 on both sides can be raised and lowered synchronously, and the height of the laser emitter 4 and the laser receiver 5 can be adjusted at the same time.
[0028] In order to accurately adjust the height, the lifting assembly includes a bearing 6 arranged on the left side of the top of the support frame 1, a rotating shaft is provided on the bearing 6, and a screw 7 is provided on the top of the rotating shaft, a handwheel 8 is provided on the top of the screw 7, a connecting frame 9 is screwed on the screw 7, and the bottom of the connecting frame 9 is connected to the left mounting rod 3. By rotating the handwheel 8, the screw 7 rotates accordingly, and the connecting frame 9 can drive the left mounting rod 3 to rise and fall.
[0029] The sides of the mounting rods 3 on both sides that are away from each other are in contact with the inner walls on both sides of the support frame 1 respectively.
[0030] An electric telescopic rod 13 is provided at the middle position of the top of the support frame 1. The output end of the electric telescopic rod 13 is hinged with an oblique rod 14 on both sides. The tops of the oblique rods 14 on both sides are hinged with push rods 11. The sides of the push rods 11 on both sides that are away from each other are in contact with the opposite sides of the mounting rods 3 on both sides, so that the mounting rods 3 can be fixed, thereby ensuring the high stability of the laser transmitter 4 and the laser receiver 5 to ensure the stability of the yarn hairiness detection. When it needs to be loosened, the output end of the electric telescopic rod 13 is moved downward, so that the oblique rod 14 can pull the push rod 11 away from the mounting rod 3.
[0031] Example 2
[0032] Reference Figure 1 In order to enable the push rod 11 to move laterally, a guide sleeve 12 for the push rod 11 to pass through laterally is provided on the support frame 1.
