Description

Technical Field

[0001] The invention belongs to the technical field of fabric wear resistance detection, and in particular relates to a fabric wear resistance detection device. Background Art

[0002] In the textile industry, the wear resistance of fabrics is one of the key indicators to measure their quality and service life. Among the various instruments currently used for textile wear resistance testing, the Martindale Abrasion Tester has become a highly anticipated device due to its wide range of applications. Its operation process is simple and convenient, and it cleverly uses the unique motion trajectory mode of the Lissajous curve to effectively achieve accurate testing of fabric wear resistance, thus occupying an important position in the field of textile testing, providing strong support and guarantee for quality control and product development in the textile industry, and playing an irreplaceable and important role in the textile industry chain;

[0003] The Chinese patent with the publication number CN204064837U discloses a Martindale wear tester, including a horizontal workbench, a grinding table is arranged on the workbench, a cover plate is arranged above the workbench, and a grinding head assembly corresponding to the grinding table is arranged on the cover plate; the grinding head assembly includes a grinding head and a grinding head pressure rod, a grinding head bottom pressure ring for pressing the sample is arranged at the bottom of the grinding head, and a grinding head upper cover ring for fixing the grinding head bottom pressure ring is arranged at the upper part of the grinding head, the bottom of the grinding head pressure rod is connected to the grinding head, and a fixed value weight is arranged at the top of the grinding head pressure rod; the grinding head is columnar, and a step seat connected to the grinding head upper cover ring is arranged at the upper part, and a chamfer is arranged at the lower end; the grinding head bottom pressure ring includes a pressing surface matched with the grinding head chamfer and a pulling surface matched with the outer wall of the grinding head, and the pulling surface is an inclined surface, and its bottommost part forms a pressing fit with the grinding head, and other parts form a clearance fit with the grinding head; a level is arranged on the horizontal plane of the workbench. Thus, a Martindale wear tester is proposed, which enables the grinding head assembly to efficiently and smoothly fix the sample and detect whether the instrument is placed horizontally.

[0004] Although the above-mentioned tester can enable the grinding head assembly to efficiently and smoothly fix the sample and detect whether the instrument is placed horizontally, in the wear resistance test, not only the large Lissajous curve test but also the small Lissajous curve test is required. As a result, after the test is completed, it is necessary to manually adjust the large and small Lissajous curves, which is cumbersome and affects the test efficiency. At the same time, during the test, the ball and the push plate rub against each other, which easily leads to wear, causing the push plate to tilt slightly, which is difficult to observe with the naked eye. The tilt of the push plate causes the formed Lissajous curve to have a deviation, which leads to inaccurate detection.

[0034] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 12 As shown, the present invention provides a fabric wear resistance detection device, including a chassis 1, and also includes: three driving mechanisms 2, which are placed in the chassis 1; they are used to drive a push plate 5 to move in a horizontal direction according to a Lissajous trajectory.

[0036] The clamping assembly 3 is placed on the top of the driving mechanism 2. The present invention provides the clamping assembly 3 to facilitate the assembly and disassembly of the eccentric mechanism 4. The clamping assembly 3 is prior art and will not be described in detail.

[0037] The eccentric mechanism 4 is detachably connected to the top of the clamping assembly 3. The present invention sets the eccentric mechanism 4, and the three driving mechanisms 2 drive the eccentric mechanism 4 to move. The three eccentric mechanisms 4 cooperate to finally push the push plate 5 to move along the Lissajous trajectory.

[0038] The push plate 5 is placed on the top of the eccentric mechanism 4 and is driven by the three drive mechanisms 2 through the eccentric mechanism 4 and moves in the horizontal direction according to the Lissajous trajectory.

[0039] Multiple groups of adjustment components 6 are used to adjust the eccentric distance of the eccentric mechanism 4 in cooperation with the driving mechanism 2, so that the driving mechanism 2 drives the push plate 5 to move in the horizontal direction according to the large Lissajous trajectory or the small Lissajous trajectory through the clamping component 3 and the eccentric mechanism 4; the present invention provides the adjustment components 6, firstly, it is possible to switch between the large Lissajous trajectory and the small Lissajous trajectory, thereby eliminating the need for manual adjustment and improving the detection efficiency. Secondly, it is possible to support the push plate 5 and simultaneously detect whether the push plate 5 is tilted.

[0040] The eccentric mechanism 4 includes a docking post 401, which is plugged into the clamping component 3 and is clamped and fixed by the clamping component 3; the present invention sets the docking post 401, plugs the docking post 401 into the clamping component 3, and then adjusts the clamping component 3 so that the clamping component 3 fixes the docking post 401, thereby realizing a detachable connection between the eccentric mechanism 4 and the clamping component 3, which is convenient for later maintenance.

[0041] A fixing plate 402 is placed on top of the docking pole 401 .

[0042] The slider 403 is placed on the top of the fixed plate 402 and is slidably connected to the top of the fixed plate 402 for reset, and a first wedge-shaped portion 404 is provided on the top of the slider; specifically, a sliding groove cooperating with the slider 403 is opened on the top of the fixed plate 402, and an elastic reset member is provided between the sliding groove and the slider 403, and the elastic reset member is a spring. The present invention sets the first wedge-shaped portion 404. When the eccentric distance needs to be adjusted and the large and small Lissajous trajectories are switched, the height of the support assembly 601 is controlled to be lowered. The lowering of the height of the support assembly 601 will reduce the height of the second wedge-shaped portion 604 on the ring 602, and finally the second wedge-shaped portion 604 can cooperate with the first wedge-shaped portion 404. It should be emphasized that since the height of the first wedge-shaped portion 404 is higher than the height of the limit release rod 4062, the pressure plate 603 does not conflict with the limit release assembly 405 at this time, and then the height of the support assembly 601 is continued to be controlled to be lowered until the pressure plate 603 conflicts with the limit release assembly 406, and then the height of the support assembly 601 is continued to be controlled to be lowered, and the support assembly 60 The height reduction will drive the pressing plate 603 to move downward, and the downward movement of the pressing plate 603 will cause the limit release assembly 406 to push the limit assembly 405 to release the limit on the slider 403, and then control the driving mechanism 2 to rotate, and the driving mechanism 2 will drive the first wedge-shaped portion 404 to rotate. The rotation of the first wedge-shaped portion 404 will conflict with the second wedge-shaped portion 604. Under the reverse force of the second wedge-shaped portion 604, the first wedge-shaped portion 404 will be pushed to move toward the center of the fixed disk 402. The movement of the first wedge-shaped portion 404 will drive the slider 403 to slide, and the sliding of the slider 403 will drive the eccentric column 407 to move, thereby reducing the eccentric distance, realizing the adjustment of the eccentric distance, and then realizing the switching of the large Lissajous trajectory or the small Lissajous trajectory.

[0043] The limiting component 405 is disposed between the fixed plate 402 and the slider 403 and is used to limit the slider 403. The present invention limits the slider 403 by setting the limiting component 405, thereby avoiding the deformation of the Lissajous track caused by the displacement of the slider 403 during the detection process.

[0044] Specifically, the limiting assembly 405 includes a limiting rod 4051, which is placed in the fixed disk 402 and connected to the fixed disk 402 through an elastic reset member. The elastic reset member is a spring; two limiting holes 4052 that cooperate with the limiting rod 4051 are opened on the side wall of the slider 403.

[0045] The limit release assembly 406 is disposed between the fixed plate 402 and the limit assembly 405 , and is used to release the limit imposed on the slider 403 by the limit assembly 405 .

[0046] Specifically, the limit release assembly 406 includes a wedge-shaped matching groove 4061 formed on the limit rod 4051 .

[0047] The limit release rod 4062 is placed on the top of the fixed plate 402, and one end of the rod extends into the wedge-shaped matching groove 4061, and one end of the rod extends into the wedge-shaped matching groove 4061 and is wedge-matched with the wedge-shaped matching groove 4061. In the present invention, the limit release rod 4062 is pressed to slide downward, and the limit release rod 4062 slides downward to be wedge-matched with the wedge-shaped matching groove 4061, thereby pushing the limit rod 4051 to slide to the side away from the limit hole 4052, so that the limit rod 4051 is pulled out of the limit hole 4052, and the limit release of the slider 403 is realized.

[0048] The eccentric column 407 is placed on the top of the slider 403 and connected to the push plate 5 to push the push plate 5 to move; specifically, the height of the eccentric column 407 is higher than the sum of the heights of the ring 602 and the first wedge-shaped portion 404 .

[0049] It also includes a plurality of friction table assemblies 7 which are placed on the top of the chassis 1 .

[0050] A plurality of friction head assemblies 8 are placed on the top of the friction table assemblies 7. The number of the friction head assemblies 8 is the same as that of the friction table assemblies 7 and they correspond one to one. A push rod 9 with one end penetrating the push plate 5 is inserted on the top of the friction head assemblies 8. A counterweight block 10 is sleeved on the top of the push rod 9.

[0051] Specifically, the present invention is used to fix the standard felt and wool cloth samples by setting a friction table assembly 7. The friction table assembly 7 includes a friction table 701, and a positioning column 702 is fixed on the peripheral side wall thereof.

[0052] The fixing cover 703 is sleeved on the outside of the friction platform 701 and has a spiral groove 704 on its side for matching with the positioning column 702 .

[0053] Specifically, the present invention is used to fix the friction sample by setting a friction head assembly 8. The friction head assembly 8 includes a sample fixing seat 801, which is placed on the top of the friction table 701.

[0054] The specimen friction head 802 is placed on the top of the inner side of the specimen fixing seat 801 .

[0055] The specimen pressure plate 803 is placed on the top of the specimen friction head 802 and is threadedly connected to the outer wall of the specimen fixing seat 801. A socket that cooperates with the push rod 9 is opened on the top of the pressure plate 803.

[0056] The adjustment component 6 includes two groups of support components 601 with adjustable heights and supporting the push plate 5, each group has two components, one group of support components 601 is symmetrical front to back, and the other group of support components 601 is symmetrical left to right, and pressure sensors are provided on the tops of the support components 601. By providing pressure sensors, the present invention can detect the downward pressure generated by the push plate 5 to avoid the push plate 5 from tilting and causing deformation of the Lissajous track.

[0057] Three circular rings 602 are respectively placed on the top of three eccentric mechanisms 4 and are coaxial with the corresponding fixed disks 402. The left circular ring 602 is connected to the bottom of the left support assembly 601 by sliding up and down through a reset assembly 605; the right circular ring 602 is connected to the bottom of the right support assembly 601 by sliding up and down through a reset assembly 605; the front and rear sides of the middle circular ring 602 are both connected to the lower parts of two front-to-back symmetrical support assemblies 601 by sliding up and down through a reset assembly 605. In the present invention, since the front-to-back symmetrically arranged support assemblies 601 are connected to the same circular ring 602, by setting the reset assembly 605, the front-to-back symmetrically arranged support assemblies 601 can move up and down relatively, thereby achieving leveling.

[0058] The pressure plate 603 is placed on the inner wall of the ring 602 and corresponds to the limit release assembly 406. By setting the pressure plate 603, the present invention can enable the support assembly 601 to drive the pressure plate 603 to move downward to press the limit release rod 4062, thereby releasing the limit of the slider 403.

[0059] The second wedge-shaped portion 604 is placed on the inner wall of the ring 602 and is wedge-matched with the first wedge-shaped portion 404 to push the slider 403 to move; the height of the first wedge-shaped portion 404 is higher than the height of the limit release rod 4062; the present invention sets the second wedge-shaped portion 604 so that the second wedge-shaped portion 604 and the first wedge-shaped portion 404 are wedge-matched to push the slider 403 to slide, thereby adjusting the eccentricity.

[0060] The support assembly 601 includes an electric telescopic rod 6011 , which is placed on the top of the chassis 1 . The present invention achieves height adjustment of the support tray 6012 by setting the electric telescopic rod 6011 and controlling the extension and retraction of the electric telescopic rod 6011 .

[0061] The supporting tray 6012 is placed on the top of the electric telescopic rod 6011.

[0062] The ball bearings 6013 are placed in the support tray 6012. The present invention supports the push plate 5 by providing the ball bearings 6013.

[0063] The pressure sensor is placed between the support tray 6012 and the ball 6013. The present invention is used to monitor the downward pressure generated by the pressure sensor in real time by setting the pressure sensor. When the pressure value detected by the pressure sensor is less than the preset value, it indicates that the push plate 5 may be tilted, which may easily cause the Lissajous track to deform. Then the alarm is controlled to alarm, and the corresponding electric telescopic rod 6011 is controlled to extend until the pressure value detected by the pressure sensor is equal to the preset value. In this way, leveling is achieved to prevent the push plate 5 from tilting and causing the Lissajous track to deform.

[0064] The reset assembly 605 includes a square guide rod 6051, which is threadedly connected to the bottom of the support assembly 601 and is connected to the ring 602. The present invention realizes the sliding guidance of the ring 602 by arranging the square guide rod 6051.

[0065] The resetting elastic member 6052 is sleeved on the square guide rod 6051 and is located at the bottom of the circular ring 602 . The present invention realizes pushing the circular ring 602 to reset by setting the resetting elastic member 6052 .

[0066] The anti-slipping piece 6053 is threadedly connected to the bottom of the square guide rod 6051. The present invention provides the anti-slipping piece 6053, and by unscrewing the anti-slipping piece 6053, the ring 602 can be removed from the square guide rod 6051, so that later maintenance is convenient.

[0067] The driving mechanism 2 includes a driving motor, which is placed in the chassis 1 and has an output shaft that passes through the top of the chassis 1 .

[0068] During the test, the standard felt and wool cloth samples are first fixed on the friction table assembly 7.

[0069] Then fix the friction sample in the friction head assembly 8, then place the friction head assembly 8 on the friction table assembly 7, place the push plate 5 on the top of the eccentric mechanism 4, and make the push plate 5 and the eccentric column 407 transmission connected; then insert the push rod 9 into the push plate 5, and make one end of the inserted push plate 5 plug into the friction head assembly 8, and then place a suitable counterweight 10 on the top of the push rod 9 to complete the installation.

[0070] After installation is completed, the electric telescopic rod 6011 is controlled to extend until the pressure sensor detects that the pressure value is equal to the preset value and stops, thereby firstly forming support around the push plate 5, at which time the ball 6013 contacts the push plate 5, and the ring 602 is located at the top of the first wedge-shaped portion 404. The first wedge-shaped portion 404 and the second wedge-shaped portion 604 cannot cooperate; then, the driving mechanism 2 is controlled to work, and the driving mechanism 2 works to drive the eccentric mechanism 4 to rotate, and the rotation of the eccentric mechanism 4 can drive the push plate 5 to move according to the Lissajous trajectory, and the movement of the push plate 5 will drive the push rod 9 to move, and the movement of the push rod 9 will drive the friction head assembly 8 to move, and finally the wear resistance detection is realized.

[0071] When it is necessary to switch between the large and small Lissajous trajectories, first push the push plate 5 upwards manually. At this time, the push plate 5 moves up and separates from the eccentric mechanism 4, and is not connected to the eccentric mechanism 4 in transmission. Then, the three driving mechanisms 2 are controlled to rotate, so that the driving mechanisms 2 rotate to the position where the first wedge-shaped portion 404 on the eccentric mechanism 4 cooperates with the corresponding second wedge-shaped portion 604. Then, the electric telescopic rods 6011 corresponding to the rings 602 are controlled to contract. The contraction of the electric telescopic rods 6011 will drive the support tray 6012 to descend. The descent of the support tray 6012 will drive the ring 602 to descend. The descent of the ring 602 will drive the pressure plate 603 and the second wedge 604 to move downward. Since the height of the first wedge 404 is higher than the limit release rod 4062, the pressure plate 603 and the second wedge 604 will move downward. The height of the support assembly 601 is firstly adjusted, and the first wedge-shaped portion 404 and the second wedge-shaped portion 604 are in a mating state. At this time, the pressure plate 603 does not conflict with the limit release component 405. Then, the electric telescopic rod 6011 is continuously controlled to be retracted until the pressure plate 603 conflicts with the limit release component 406. Then, the electric telescopic rod 6011 is continuously controlled to be retracted. The height of the support component 601 is reduced, which will drive the pressure plate 603 to move downward. The downward movement of the pressure plate 603 will press the limit release rod 4062 downward. The limit release rod 4062 slides downward and will wedge-match with the wedge-shaped matching groove 4061, thereby pushing the limit rod 4051 to slide to the side away from the limit hole 4052, so that the limit rod 4051 is pulled out of the limit hole 4052, and the limit release of the slider 403 is realized. Then, the driving mechanism 2 is controlled to rotate, and the rotation of the driving mechanism 2 will drive the first wedge-shaped portion 404 to rotate. Since the slider 403 is in a limit release state at this time, and since the first wedge-shaped portion 404 and the second wedge-shaped portion 604 are in a wedge-shaped matching state, the rotation of the first wedge-shaped portion 404 will conflict with the second wedge-shaped portion 604. Under the reverse force of the wedge-shaped surface of the second wedge-shaped portion 604, the first wedge-shaped portion 404 will be pushed to move toward the center of the fixed disk 402. The movement of the first wedge-shaped portion 404 will drive the slider 403 to slide, and the sliding of the slider 403 will drive the eccentric column 407 to move, thereby reducing the eccentric distance, realizing the adjustment of the eccentric distance, and then realizing the switching to the small Lissajous trajectory; then, by controlling the extension of the electric telescopic rod 6011, the electric telescopic rod 6011 The elongation will drive the ring 602 to move upward, and the upward movement of the ring 602 will drive the pressure plate 603 and the second wedge-shaped portion 604 to move upward. First, when the second wedge-shaped portion 604 and the first wedge-shaped portion 404 maintain a wedge-shaped fit, the pressure on the limit release rod 4062 is released, and the limit release rod 4062 is no longer pressed. Under the elastic force of the elastic reset member, the limit rod 4051 is pushed into the limit hole 4052 to limit the slider 403, and then the electric telescopic rod 6011 is continued to be controlled to the state where the second wedge-shaped portion 604 and the first wedge-shaped portion 404 are no longer matched, and then the three driving mechanisms 2 are controlled to rotate, so that the driving mechanism 2 drives the eccentric column 407 on the eccentric mechanism 4 to rotate to a state where they cooperate with each other to form a Lissajous trajectory.Then, the push plate 5 is placed downward so as to be transmission-connected with the eccentric column 407 on the eccentric mechanism 4, thereby the small Lissajous track wear resistance test can be performed.

[0072] During the detection, when the pressure value detected by one of the pressure sensors is less than the preset value, it indicates that the push plate 5 may be tilted, which may easily cause the Lissajous track to deform. Then the alarm is controlled to alarm, and the corresponding electric telescopic rod 6011 is controlled to extend until the pressure value detected by the pressure sensor is equal to the preset value. Thus, leveling is achieved to prevent the push plate 5 from tilting and causing the Lissajous track to deform.

[0073] It should be emphasized that the present invention can not only quickly switch the detection of large and small Lissajous trajectories, but also can promptly correct the unstable support caused by the wear of the ball 6013. At the same time, for existing equipment that does not have the ability to quickly switch between large and small Lissajous trajectories, it is only necessary to add the eccentric mechanism 4 and the adjustment component 6 of the present invention, thereby achieving the above purpose without replacing new equipment.

[0074] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
