Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically to a multi-station rubbing color fastness tester. Background Technology

[0002] A rubbing fastness tester is a testing instrument used to assess the fastness of color in textiles, knitwear, leather and other industries through rubbing tests.

[0003] A color fastness tester for rubbing (patent number CN202322756806.0) has a reciprocating motion mechanism fixedly connected to the upper surface of the test platform, capable of wiping the test cloth back and forth. An eccentric mechanism is fixedly connected to one side of the test platform, driving the reciprocating motion mechanism. A clamping mechanism for holding the test cloth is fixedly installed on one side of the upper surface of the test platform. A support mechanism is fixedly installed below the reciprocating motion mechanism at the upper end of the test platform. This application uses the clamping mechanism to hold and fix the test cloth on the test platform, and the eccentric mechanism drives the reciprocating motion mechanism to continuously wipe the white cloth back and forth, ensuring consistent wiping distance and force each time, improving efficiency and effectiveness. The support mechanism allows the horizontal plate to be lifted for easy disassembly of the white cloth. The above structure only has a single station (single friction head), while the color fastness test of textile samples usually requires two sets of tests at the same time: dry rubbing color fastness and wet rubbing color fastness. Each set of tests also requires color fastness tests in the radial and weft directions of the textile sample. This means that the textile sample needs to undergo four rubbing color fastness tests. The number of color fastness tests is large, and using a single station operation is not conducive to improving work efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a multi-station rubbing color fastness tester. It adopts a dual-station design, completes two tests at once, greatly improves testing efficiency, and increases the testing speed of laboratory rubbing color fastness. It can also perform warp and weft rubbing tests by rotating the fabric clamping table. It is widely applicable to dry and wet rubbing color fastness tests of conventional fabrics, pile fabrics and woven fabrics.

[0005] The purpose of this utility model is achieved as follows:

[0006] A multi-station rubbing color fastness tester includes a test platform, a drive box, a lever arm, and a crank-connecting rod mechanism. The crank-connecting rod mechanism includes a crank and a connecting rod. One end of the connecting rod is hinged to the crank, and the other end is hinged to the right side of the lever arm. A drive motor in the drive box drives the crank to rotate, causing the connecting rod to drive the lever arm to perform reciprocating linear motion on the test platform. A Y-shaped fixing seat is provided on the front side of the lever arm. The Y-shaped fixing seat is integrally formed and includes a central connecting section and symmetrically arranged friction head mounting sections. The connecting section connects to the lever arm. Each friction head mounting section is equipped with a friction component. The two friction components are arranged in the same longitudinal direction and are symmetrically distributed front and back.

[0007] Preferably, the connecting segment is inserted into the mounting groove on the front side of the lever arm and fixed with bolts.

[0008] Preferably, the friction assembly includes a threaded sleeve, a friction rod, and a friction head. The threaded sleeve is fitted onto the friction head mounting section, the friction rod is threaded into the threaded sleeve, and the friction head is threaded to the bottom of the friction rod.

[0009] Preferably, the test stand is a split type, including a rotating fabric clamping platform and a test stand body. The rotating fabric clamping platform is fixed to the front end of the test stand body by a slewing bearing. The textile sample is clamped on the rotating fabric clamping platform, and the friction assembly is correspondingly arranged above the textile sample.

[0010] Preferably, the test bench body is divided into high and low layers, with the slewing bearing fixed to the lower layer at the front end of the test bench body, and the rotating fabric clamping platform flush with the upper layer at the rear end of the test bench body.

[0011] Preferably, the inner ring of the slewing bearing is fixed to the lower layer of the test bench body, and the outer ring of the slewing bearing is connected to the rotating fabric clamping table.

[0012] Preferably, a limiting rod is provided between the rotating fabric clamping table and the lower layer of the test table body, the rotating fabric clamping table is provided with an upper limiting hole corresponding to the limiting rod, and the lower layer of the test table body is provided with a lower limiting hole corresponding to the limiting rod.

[0013] Preferably, two upper limit holes are symmetrically distributed on the left and right sides of the rotating fabric clamping table, and eight lower limit holes are evenly distributed in the circumference of the slewing bearing to achieve fixation after the rotating fabric clamping table rotates 45°.

[0014] The beneficial effects of this utility model are:

[0015] Adopting a dual-station design, two friction components are installed by setting a Y-shaped fixed seat at the end of the lever arm. The two friction components are distributed longitudinally back and forth, so that the two friction components do not interfere with each other when performing color fastness tests on different areas of the textile sample. Two tests can be completed at once, which greatly improves the testing efficiency and increases the testing speed of laboratory rubbing color fastness. It can also perform warp and weft rubbing tests by rotating the fabric clamping table. It is widely applicable to dry and wet rubbing color fastness tests of conventional fabrics, pile fabrics and woven fabrics. Attached Figure Description

Detailed Implementation

[0021] See Figure 1-3 This utility model relates to a multi-station rubbing color fastness tester, including a test platform 1, a drive box 2, a lever arm 3, and a crank-connecting rod mechanism. The crank-connecting rod mechanism includes a crank 4 and a connecting rod 5. One end of the connecting rod 5 is hinged to the crank 4, and the other end is hinged to the right side of the lever arm 3. The drive motor in the drive box 2 drives the crank 4 to rotate, so that the connecting rod 5 drives the lever arm 3 to perform reciprocating linear motion on the test platform 1. A Y-shaped fixing seat 6 is provided on the front side of the lever arm 3. The Y-shaped fixing seat 6 is integrally formed and includes a central connecting section 6.1 and symmetrically arranged friction head mounting sections 6.2. The connecting section 6.1 is inserted into the mounting groove 3.1 on the front side of the lever arm 3 and fixed by bolts. Each friction head mounting section 6.2 is equipped with a friction component 7. The two friction components 7 are arranged in the same longitudinal direction and are symmetrically distributed front and back, so that the friction starting point of the two friction components 7 is consistent. The two friction components 7 are distributed at intervals in the longitudinal direction, so that the two friction components 7 do not interfere with each other when performing color fastness tests on different areas of the textile sample.

[0022] The friction assembly 7 includes a threaded sleeve 7.1, a friction rod 7.2, and a friction head 7.3. The threaded sleeve 7.1 is fitted onto the friction head mounting section 6.2. The friction rod 7.2 is screwed into the threaded sleeve 7.1, and the friction head 7.3 is screwed to the bottom of the friction rod 7.2. It allows for quick switching between a round and square friction head as needed. The friction head 7.3 is used to mount a standard white friction cloth, which is clamped by a copper sleeve (not shown in the figure). The shape of the copper sleeve is adapted to the friction head, enabling the testing of color fastness to rubbing on ordinary fabrics (round friction head) and pile fabrics (square friction head). Rotating the friction rod 7.2 finely adjusts the gap between the friction cloth on the friction head and the textile sample.

[0023] The test bench 1 is a split type, including a rotating fabric clamping table 1.1 and a test bench body 1.2. The rotating fabric clamping table 1.1 is fixed to the front end of the test bench body 1.2 by a slewing bearing 8. The test bench body 1.2 is divided into high and low layers. The slewing bearing 8 is fixed to the lower layer at the front end of the test bench body 1.2, and the rotating fabric clamping table 1.1 is flush with the upper layer at the rear end of the test bench body 1.2.

[0024] The inner ring of the slewing bearing 8 is fixed to the lower layer of the test bench body 1.2, and the outer ring of the slewing bearing is connected to the rotating cloth clamping table 1.1, thereby realizing the rotation of the rotating cloth clamping table.

[0025] Textile sample 9 is clamped on a rotating clamping table 1.1. Cloth clamps 10 are provided on the left and right sides of the rotating clamping table 1.1. A limiting rod 11 is provided between the rotating clamping table 1.1 and the lower layer of the test platform body 1.2. The rotating clamping table 1.1 has upper limiting holes corresponding to the limiting rod 11, and the lower layer of the test platform body 1.2 has lower limiting holes corresponding to the limiting rod 11. Two upper limiting holes are symmetrically distributed on the left and right sides of the rotating clamping table 1.1, and eight lower limiting holes are evenly distributed around the circumference of the slewing bearing 8, achieving fixation after the rotating clamping table 1.1 rotates 45°. The radial or weft direction of the textile sample 9 is aligned with the movement direction of the friction assembly during clamping. After clamping, rotating the rotating clamping table 1.1 rotates the textile sample 9 by 45°, achieving adjustment of the warp and weft position of the textile sample 9 and improving work efficiency.

[0026] Operating instructions:

[0027] For ordinary textiles, the textile sample is fixed on a rotating cloth clamping table, and the standard white friction cloth and the standard white friction cloth with a moisture content of 95%-100% are fixed on the corresponding friction heads respectively; the warp or weft of the textile sample is aligned with the running direction of the friction head, the running speed is 1 reciprocating friction cycle per second, the friction stroke is (104±3) mm, and the downward pressure is (9±0.2) N.

[0028] Press the start button and rub for 10 cycles; remove the standard white rubbing cloth, remove any excess fibers that may affect the rating, and then conduct the assessment.

[0029] For woven products, the textile sample is fixed on the rotating clamping table, and the standard white friction cloth and the standard white friction cloth with a moisture content of 95%-100% are fixed on the corresponding friction heads respectively. When the textile sample 9 is clamped, the radial or weft direction is consistent with the movement direction of the friction assembly. After clamping, the rotating clamping table 1.1 is rotated to rotate the textile sample 9 by 45°, and the friction test is performed on the warp and weft directions of the textile sample.

[0030] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
