Description

Technical Field

[0001] This utility model belongs to the field of fabric abrasion resistance testing technology, and relates to a fabric abrasion resistance testing device with adjustable pressure. Background Technology

[0002] A significant drawback of existing fabric abrasion resistance testing processes is the inability to adjust abrasion tension. Abrasion tension refers to the magnitude of the tension experienced by a fabric sample during an abrasion test. An ideal abrasion resistance test should simulate the tension conditions experienced by fabrics in actual use. However, due to limitations of existing equipment, tension often cannot be precisely adjusted according to testing needs. This drawback stems from the design and manufacturing technology of the testing equipment, which may not provide sufficient adjustment range or precision, making it impossible to simulate the true tension state under various usage conditions. Conventional solutions include using adjustable tension testing equipment or applying pre-tension to the sample before testing. However, these methods also have drawbacks. While adjustable tension equipment provides a solution to some extent, such equipment is often expensive and complex to operate, requiring specialized knowledge for proper setup and use. Applying pre-tension to the sample, while simple and easy, may not accurately simulate tension changes during actual use, thus affecting the accuracy and repeatability of test results. Therefore, there is an urgent need for a pressure-adjustable fabric abrasion resistance testing device to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric abrasion resistance testing device with adjustable pressure, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a pressure-adjustable fabric abrasion resistance testing device, comprising: a motor and a tension groove, wherein a set of drive shafts for outputting motor power is provided on the right side of the motor, and a set of transfer case for right-angle transmission of motor power is provided on the right side of the drive shafts.

[0005] The transfer case has a set of drive shafts on the front side for exporting power. The drive shafts have a set of drive discs on the front side for driving the eccentric connecting seat to rotate eccentrically. The drive discs have a circular cross-section on the front side. The drive discs have a set of eccentric connecting seats on the upper left side for driving the outer drive rod to rotate eccentrically. The eccentric connecting seats are fixed to the drive discs by bolts. The eccentric connecting seats have a set of outer drive rods on the left side for driving the movable joint to move. The outer drive rods have a set of inner connecting rods on the left side for moving synchronously with them. The inner connecting rods are fixed to the outer drive rods.

[0006] In a preferred embodiment, the left front end of the inner connecting rod is provided with a set of movable joints for power connection with the movable sleeve, and the movable joints and the movable sleeve are connected and fixed by nuts.

[0007] In a preferred embodiment, the movable sleeve penetrates the upper end of the movable limiting support rod. The upper end of the movable limiting support rod has an inner bearing for movably connecting with the movable sleeve. The lower end of the movable limiting support rod has a movable seat for its movable limiting support. In actual use, the motor is first started, and power is transmitted to the transfer case via the drive shaft for right-angle steering. The transmission shaft on the front side of the transfer case drives the drive disc to rotate. The drive disc, through the eccentric connecting seat, causes the outer transmission rod to move eccentrically. The outer transmission rod pushes the inner connecting rod to link with the movable joint. The movable joint drives the movable sleeve to reciprocate within the inner bearing of the movable limiting support rod. The movement of the movable sleeve is transmitted to the connecting support via the upper movable bracket, thereby adjusting the tension of the fabric strip in the inner storage box. The tension adjusting roller and the winding roller cooperate to control the tightness of the fabric strip. The reset spring ensures the stability of the adjustable tension range, thus enabling the fabric strip to move stably during abrasion testing.

[0008] In a preferred embodiment, the movable seat and the lower end of the movable limiting support rod are movably positioned and connected by a set of rotating shafts, and the upper left side of the movable limiting support rod is provided with a set of upper movable brackets for driving the connecting support to swing.

The upper left side of the upper movable bracket is provided with a set of connecting supports for repeatedly pulling the fabric belt. The left side of the connecting supports is provided with a set of fabric belts whose abrasion resistance is to be tested.

[0010] In a preferred embodiment, the right side of the fabric belt is connected and fixed to the connecting support by several sets of bolts. A set of tension adjusting rollers for friction is provided on the right side of the middle position of the fabric belt. A set of tension grooves for guiding the tension movement of the tension adjusting rollers is provided on the front and rear sides of the tension adjusting rollers. A set of return springs for providing tension support to the tension adjusting rollers is provided inside the tension grooves.

[0011] In a preferred embodiment, the upper end of the fabric strip is provided with a set of winding rollers for tightening the left side of the fabric strip, and the outer side of the winding rollers is provided with a set of inner storage boxes for protecting and shielding the outer side.

[0012] In a preferred embodiment, a set of reset coil springs for providing tensile elasticity to the fabric strip is provided on both the front and rear sides of the winding roller. The left side of the fabric strip is connected and fixed to the outside of the winding roller. During operation, the motor is started first, and the drive shaft drives the transfer case to convert the power into lateral transmission. The transmission shaft drives the eccentric wheel to rotate, and drives the movable sleeve to slide back and forth in the limit support rod through the outer transmission rod. The upper movable bracket moves synchronously with the sleeve, pushing the connecting support to swing regularly, so that the fabric strip fixed on the connecting support generates reciprocating frictional motion. Adjusting the motor speed can change the swing frequency, thereby controlling the friction intensity.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the power is transmitted to the transfer case through the drive shaft for right-angle steering, the transmission shaft on the front side of the transfer case drives the drive disc to rotate, the drive disc causes the outer transmission rod to make eccentric movement through the eccentric connecting seat, the outer transmission rod pushes the inner connecting rod to link with the movable joint, the movable joint drives the movable sleeve to reciprocate in the inner bearing of the movable limit support rod, the movement of the movable sleeve is transmitted to the connecting support through the upper movable bracket, thereby adjusting the tension of the fabric belt in the inner storage box, the tension adjusting roller and the winding roller cooperate to control the tightness of the fabric belt, and the reset coil spring ensures that the tension adjustment range is stable, so that the fabric belt can maintain stable movement when the wear resistance test is performed;

[0014] During operation, the motor is started first. The drive shaft drives the transfer case to convert power into lateral transmission. The drive shaft drives the eccentric wheel to rotate, which drives the movable sleeve to slide back and forth in the limit support rod through the outer drive rod. The upper movable bracket moves synchronously with the sleeve, pushing the connecting support to swing regularly, so that the fabric belt fixed on the connecting support generates reciprocating frictional motion. Adjusting the motor speed can change the swing frequency, thereby controlling the friction intensity. Attached Figure Description
