Description

Technical Field

[0001] The utility model relates to the field of textile product testing instruments, in particular to a nail hammer wire snagging performance tester. Background Art

[0002] With the rapid development of the textile industry, the quality and performance requirements of textiles are getting higher and higher. As an important indicator of textiles, snagging performance plays a vital role in evaluating the performance and comfort of fabrics. The hammer snagging tester is suitable for testing the snagging performance of outerwear knitted fabrics and woven fabrics, especially chemical fiber filaments and their textured yarn fabrics. It can quickly detect the difficulty of fabrics to produce snagging under normal wearing conditions. During the test, the cylindrical sample is put on the drum, and the hammer suspended by a chain is placed on the surface of the sample. When the drum rotates at a constant speed, the hammer randomly flips and jumps on the surface of the sample, and hooks the sample, resulting in snagging on the surface of the sample. After the specified number of revolutions, the degree of snagging of the sample is rated by comparing with the standard sample.

[0003] At present, Chinese patent publication number CN203393493U discloses a nail hammer type snag tester, including a chassis, a control box on the right side of the chassis, and the chassis and the control box are installed on the bottom plate; a plurality of rollers are installed on the chassis, and the rollers are fixed to the front fixing plate and the rear fixing plate through bearings, and the front fixing plate and the rear fixing plate are installed on a connecting block, and the connecting block is fixed on the bottom plate, and the bearing is connected to the reducer, and the reducer is installed in the chassis; a plurality of brackets are installed on the chassis, and an upper rod is installed on the top of the bracket, and the upper rod is located above the roller, and a pick rod seat is fixed at the front end of the upper rod, and a knob is fixed at the lower end of the pick rod seat, and an iron chain is fixed at the lower end of the knob, and a nail hammer with convex thorns is fixed at the lower end of the iron chain, and the nail hammer is placed on the roller. It can be widely used in the determination of the anti-snagging performance of textiles such as clothing and home decoration, and its determination accuracy is high, and it is easier to promote and apply.

[0004] However, in actual use, since the radial cross-section of the roller of the existing tester is a circular structure, the hammer may stay in one position instead of jumping randomly, forming a scratching effect on the surface of the fabric, failing to achieve the ideal simulation of wire hooking, resulting in poor test results. Utility Model Content

[0005] Therefore, in view of the above-mentioned problems, the utility model proposes a nail hammer wire snagging performance tester to solve the problem that the tester in the prior art has a poor test effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] The roller mechanism comprises a rotating roller and a motor. The rotating roller is rotatably arranged on a workbench, and the motor is arranged inside the workbench. The output shaft of the motor is drivingly connected with the rotating roller.

[0010] The rotating roller comprises a roller shaft and a roller body fixedly sleeved outside the roller shaft, the roller shaft is drivingly connected to the output end of the motor, the radial cross section of the roller body is elliptical, and the roller shaft is eccentrically arranged on the roller body.

[0011] Furthermore, a vertical mounting hole is provided at one end of the connecting head away from the suspension arm; the adjusting mechanism includes a threaded rod and a clamping piece, the clamping piece is spherical, the clamping piece is sleeved on the threaded rod and threadedly connected to the threaded rod; the diameter of the mounting hole is larger than the diameter of the threaded rod and smaller than the diameter of the clamping piece; the threaded rod passes through the mounting hole, the lower end of the threaded rod is fixedly connected to the chain, and the clamping piece is arranged above the mounting hole.

[0012] Furthermore, a handle is threadedly connected to the threaded rod, and the handle is located above the clamping piece.

[0014] Furthermore, a tray is fixedly connected to the bracket, and the tray is located between the suspension arm and the lifting rod.

[0015] Furthermore, the outer surface of the rotating roller is covered with a felt sleeve.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. By setting a rotating roller with an eccentric structure, the contact point between the hammer and the rotating roller will constantly change during the rotation of the rotating roller, so that the hammer will continuously jump on the surface of the rotating roller and repeatedly hit the surface of the fabric, achieving the effect of simulating wire hooking and ensuring the test effect.
