Description

Technical Field

[0001] This utility model relates to testing instruments, and more specifically, to an abrasion resistance tester. Background Technology

[0002] The color fastness to abrasion of fabric is an important indicator of fabric performance. Current abrasion testers have the following drawbacks: there is only one abrasion head and its position cannot be adjusted. When rubbing several different areas of a fabric, only one area can be rubbed at a time, which is inefficient. Furthermore, when rubbing other areas, the fabric needs to be moved, which is inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an abrasion resistance tester. By setting multiple friction mechanisms, each of which can move along the width of the test platform, it can not only perform friction operations on multiple areas of a fabric at the same time, but also facilitate the adjustment of the position of the friction head.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wear resistance tester includes a base, a test platform, a push rod, and multiple friction mechanisms. The test platform is installed on the upper part of the base. One end of the push rod is connected to multiple friction mechanisms. The friction mechanisms are located above the test platform. Adjacent friction mechanisms can move closer to or further away from each other. Each friction mechanism includes a friction head that can abut against the upper part of the test platform. The push rod is movable so that the friction head can reciprocate back and forth on the upper part of the test platform.

[0005] Furthermore, the push rod end is provided with a connecting frame, and the connecting frame is provided with a screw and a guide rod that are parallel to each other and arranged along the width direction of the test platform. The friction mechanism is respectively sleeved on the outside of the screw and the guide rod. The friction mechanism is threadedly connected to the screw and can move along the guide rod.

[0006] Furthermore, the friction mechanism includes a second knob and a movable block. The second knob is threadedly connected to a screw, the friction head is connected to the movable block, the movable block is movably connected to the second knob, the guide rod passes through the movable block, and the second knob can rotate to drive the movable block to move.

[0007] Furthermore, the second knob has annular sleeves on both sides, coaxial with the second knob. The movable block includes two connecting pieces, which are respectively sleeved on the outside of the corresponding annular sleeves. The annular sleeves can rotate within the connecting pieces, and the guide rod passes through the connecting pieces.

[0008] Furthermore, the upper end of the friction head passes through the movable block, and a locking bolt is threadedly connected to the side of the movable block. The end of the locking bolt can abut against the side of the friction head to fix the position of the friction head.

[0009] Furthermore, the upper part of the test platform is provided with support frames at both ends along the length direction, and the support frames are provided with pressure blocks that can abut against the upper surface of the test platform.

[0010] Furthermore, the upper part of the pressure block is provided with a limiting rod and a pull rod, both of which pass through the upper part of the support frame. A spring is sleeved on the outside of the limiting rod, with the lower end of the spring abutting against the upper part of the pressure block and the upper end abutting against the lower surface of the upper part of the support frame.

[0011] Furthermore, the upper part of the base is provided with a guide plate, which is located on both sides of the push rod. The guide plate is provided with a guide groove. A slide rod is fixed at the end of the push rod away from the friction mechanism. The two ends of the slide rod are respectively inserted into the guide grooves on both sides. A control box is provided on the side of the base. A crank and a motor are provided on the side of the control box. The motor can drive the crank to move. The crank and the slide rod are connected by a connecting rod. The two ends of the connecting rod are respectively movably connected to the crank and the slide rod. The crank can drive the slide rod to reciprocate along the guide groove.

[0012] Furthermore, the upper part of the base is provided with a support seat, which is located between the test platform and the guide plate. A first knob is provided on the outside of the support seat, and a rotating block is connected inside the support seat. The rotating block is tightly fitted to the inside of the support seat. The first knob is fixedly connected to the rotating block and can drive the rotating block to rotate.

[0013] Furthermore, a counterweight is installed on the upper part of the push rod near the friction mechanism.

[0014] In summary, this utility model has the following beneficial effects:

[0015] In this embodiment, there are two friction mechanisms. By setting multiple friction mechanisms, multiple surfaces of the fabric can be rubbed simultaneously, which is highly efficient. By rotating the second knob of the corresponding friction mechanism, the friction head and the movable block can be moved along the guide rod, thereby adjusting the position of the friction head. This not only makes the adjustment operation convenient and avoids the friction mechanism from shifting back, ensuring high reliability, but also facilitates friction testing.

[0020] 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.

[0021] like Figures 1 to 3 As shown, this embodiment discloses an abrasion resistance tester, including a base 1, a test platform 2, a push rod 4, and multiple friction mechanisms 5. The test platform 2 is installed on the upper part of the base 1. One end of the push rod 4 is connected to multiple friction mechanisms 5. The friction mechanisms 5 are located above the test platform 2. Each friction mechanism 5 includes a friction head 51. The friction head 51 can abut against the upper part of the test platform 2. The push rod 4 is movable so that the friction head 51 can reciprocate back and forth on the upper part of the test platform 2.

[0022] Specifically, the base 1 has a guide plate 11 on its upper part, the guide plate 11 is located on both sides of the push rod 4, the guide plate 11 has a guide groove 12 inside, the end of the push rod 4 away from the friction mechanism 5 is fixed with a slide rod 41, the two ends of the slide rod 41 are respectively inserted into the guide grooves 12 on both sides, the base 1 has a control box 3 on its side, the control box 3 has a crank 31 and a motor 32 on its side, the motor 32 can drive the crank 31 to move, the crank 31 and the slide rod 41 are connected by a connecting rod 6, the two ends of the connecting rod 6 are respectively movably connected to the crank 31 and the slide rod 41, the crank 31 can drive the slide rod 41 to reciprocate along the guide groove 12.

[0023] In use, the fabric to be tested is fixed on the surface of the test platform 2, the lower part of the friction head 51 abuts against the fabric surface, the motor 32 works to drive the crank 31 to swing back and forth, and through the connecting rod 6 drives the push rod 4 to swing back and forth, so that the friction head 51 can perform reciprocating friction on the fabric surface to achieve the abrasion resistance test of the fabric.

[0024] The control box 3 is equipped with a linkage mechanism that enables the motor 32 to drive the crank 31 to swing. The control box 3 and its internal linkage mechanism are existing technologies, so they will not be described in detail in the manual.

[0025] The base 1 has a support seat 13 on its upper part. The support seat 13 is located between the test platform 2 and the guide plate 11. The support seat 13 has a first knob 14 on its outer side. The support seat 13 has a rotating block 8 connected inside. The rotating block 8 is tightly fitted to the inner side of the support seat 13. The first knob 14 is fixedly connected to the rotating block 8 and can drive the rotating block 8 to rotate. The two ends of the rotating block 8 are connected to the two sides of the support seat 13. By rotating the first knob 14, the rotating block 8 can be driven to rotate, thereby supporting the push rod 4.

[0026] After use, turn the first knob 14 to rotate the rotating block 8. The rotating block 8 pushes the push rod 4, causing the friction head 51 to detach from the fabric, thus facilitating the removal of the fabric after testing.

[0027] A counterweight 9 is installed on the upper part of the push rod 4 near the friction mechanism 5. The counterweight 9 can increase the pressure of the friction head 51 on the fabric surface. By replacing the counterweight 9 with different weights, the fabric surface abrasion resistance test can be carried out under different pressures.

[0028] Two adjacent friction mechanisms 5 can move closer or further apart. Specifically, the end of the push rod 4 is provided with a connecting frame 42, and the connecting frame 42 contains a screw 43 and a guide rod 44 that are parallel to each other and arranged along the width direction of the test bench 2. The friction mechanism 5 is respectively sleeved on the outside of the screw 43 and the guide rod 44. The friction mechanism 5 is threadedly connected to the screw 43. The friction mechanism 5 can move along the guide rod 44. The friction mechanism 5 includes a second knob 52 and a movable block 53. The second knob 52 is threadedly connected to the screw 43. The wiping head 51 is connected to the movable block 53, which is movably connected to the second knob 52. The guide rod 44 passes through the movable block 53. The second knob 52 can rotate to drive the movable block 53 to move. The second knob 52 has annular sleeves 521 on both sides, which are coaxial with the second knob 52. The movable block 53 includes two connecting pieces 531, which are respectively sleeved on the outside of the corresponding annular sleeves 521. The annular sleeves 521 can rotate within the connecting pieces 531. The guide rod 44 passes through the connecting pieces 531.

[0029] like Figure 2 and Figure 3As shown, there are two friction mechanisms 5 in this embodiment. By setting multiple friction mechanisms 5, multiple surfaces of the fabric can be rubbed simultaneously, which is highly efficient. By rotating the second knob 52 of the corresponding friction mechanism 5, the friction head 51 and the movable block 53 can be moved along the guide rod 44, thereby adjusting the position of the friction head 51. This not only makes the adjustment operation convenient and avoids the friction mechanism 5 from shifting back, but also ensures high reliability and facilitates friction testing.

[0030] The upper end of the friction head 51 passes through the movable block 53, and the side of the movable block 53 is threaded with a locking bolt 54. The end of the locking bolt 54 can abut against the side of the friction head 51 to fix the position of the friction head 51. Through the above design, the height of the friction head 51 can be adjusted, which is convenient for better wear resistance testing.

[0031] The test platform 2 has support frames 21 at both ends along its length on the upper part. The support frames 21 have pressure blocks 7 inside. The pressure blocks 7 can abut against the upper surface of the test platform 2. Specifically, the pressure blocks 7 have a limiting rod 71 and a pull rod 22 on the upper part. The limiting rod 71 and the pull rod 22 both pass through the upper part of the support frame 21. The limiting rod 71 has a spring 72 sleeved on the outside. The lower end of the spring 72 abuts against the upper part of the pressure block 7 and the upper end abuts against the lower surface of the upper part of the support frame 21.

[0032] When it is necessary to fix the fabric to be tested, place the fabric on the upper part of the test platform 2, pull the lever 22 on one side to drive the pressure block 7 to rise and detach from the test platform 2, then place one side of the fabric under the pressure block 7, release the lever 22, and the pressure block 7 will descend under the elastic force of the spring 72 and press against the fabric to fix one side of the fabric. After one side of the fabric is fixed, fix the other side of the fabric in the same way. Through the above design, the fabric to be tested can be effectively fixed and the operation is convenient.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
