Background Art

The webbing is a warp-woven textile. In order to ensure the performance of the webbing and the appearance of the finished product, the wear resistance of the webbing needs to be tested before it leaves the factory. The traditional testing method is to fix one end of the webbing with a fixed tool, wrap a cylindrical friction rod around the other end, and then drive the webbing to move back and forth manually or with professional equipment to achieve friction between the webbing and the friction rod. For example, a webbing wear resistance testing device disclosed in publication number CN208125543U includes a test platform, a first friction component for testing the length direction of the webbing, a drive component, a fixed component, and a second friction component for testing the width direction of the webbing. The first friction component includes a bracket arranged on one side of the test platform, a plurality of fixed blocks arranged on the bracket, and a friction rod inserted into the fixed block; one end of the webbing is fixed to the drive component through a fixing mechanism, and the drive component drives the webbing to move back and forth. The other end of the webbing is wrapped around a friction rod and then fixed to a fixed assembly; the second friction assembly includes a workbench arranged at the output end of the lifting cylinder and a grinding wheel component arranged on the test platform. The grinding wheel component can roll along the width direction of the webbing to meet the wear resistance test in both the length and width directions, thereby improving the precision and accuracy of the test, and the webbing is easy to disassemble and assemble, and is easy to maintain.

However, in the disclosed technology, the wear resistance test can only be performed on a specific part of the webbing through the rotating grinding wheel, and the test position is single; and during the use of the webbing, there are many friction factors generated with it, the most common of which is the friction between the webbing and a static object or a dynamic object, which cannot be achieved in the disclosed technology. Therefore, in general, it is difficult to meet the diverse testing requirements of the webbing.

DETAILED DESCRIPTION

The present invention is further described below in conjunction with the embodiments, but does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

Referring to Figures 1 to 4, a wear-resistant testing device for a webbing of the utility model includes a machine 1. The machine 1 includes a horizontal plate 11 and a vertical plate 12. The vertical plate 12 is fixedly installed above the horizontal plate 11, and the winding roller 1 2, the winding roller 2 3 and the wear-resistant test roller 4 are all installed on the vertical plate 12. The four end corners below the horizontal plate 11 are screwed with anchor bolts 13 to facilitate the leveling of the machine 1. In addition, a plurality of right-angle pieces 14 are fixedly installed at the connection between the horizontal plate 11 and the vertical plate 12 by bolts, and a reinforcing plate 15 is welded in the right-angle piece 14 to improve the stability of the connection between the horizontal plate 11 and the vertical plate 12.

Winding roller 1 2, winding roller 2 3 and wear-resistant test roller 4 are rotatably installed on one side of the machine 1. Winding roller 1 2 and winding roller 2 3 are arranged on the same horizontal plane. Wear-resistant test roller 4 is staggered between winding roller 1 2 and winding roller 2 3. Specifically, it can be located below winding roller 1 2 and winding roller 2 3, so that the three rollers form a triangular structure. A webbing 5 is provided between winding roller 1 2 and winding roller 2 3, and the two ends of webbing 5 are respectively fixed on the corresponding winding rollers. The structure in which webbing 5 is fixed on the winding roller belongs to the prior art. The fixing method of the webbing on the winding roller on the disclosed webbing winding device can be referred to, and this article will not discuss it further. Webbing 5 is wound on wear-resistant test roller 4.

Through such an arrangement, when one of the reel-up rollers rotates to reel up the webbing 5, the wear-resistant test roller 4 tensions the webbing 5, thereby achieving friction on the webbing 5, thereby achieving a wear-resistant test on the webbing 5. In addition, due to the triangular arrangement structure of the three rollers, the friction surface of the webbing 5 is located at the top, which facilitates the staff to observe the wear-resistant test surface on the webbing 5.

In order to realize the rotation of the roller body, the other side of the machine 1 of this embodiment is equipped with motor 1 6, motor 2 7 and motor 3 8. The drive shaft of motor 1 6 is fixedly connected to winding roller 1 2, the drive shaft of motor 2 7 is fixedly connected to winding roller 2 3, and the drive shaft of motor 3 8 is fixedly connected to wear-resistant test roller 4. Among them, motor 1 6 and motor 2 7 are both stepper motors, and their drive shafts can rotate freely when the motors are not powered on. Motor 3 8 is a reduction motor with a self-locking function, that is, its drive shaft cannot rotate under the condition of external force. The purpose of this setting is that, since the stepper motor has the function of adjustable speed, it is convenient to adjust the winding speed of the ribbon 5 to match the requirements of different wear-resistant test speeds. The purpose of using a reduction motor with a self-locking function in the motor 3 8 is that when the motor 3 8 is not powered on, the motor 3 8 is self-locked, and the wear-resistant test roller 4 does not rotate, so as to realize the wear-resistant test between the webbing 5 and the static wear-resistant test roller 4; when the motor 3 8 is powered on, the wear-resistant test roller 4 rotates, and its rotation direction is opposite to the winding direction of the webbing 5, so as to realize the wear-resistant test between the webbing 5 and the dynamic wear-resistant test roller 4. Therefore, the motor 1 6 and the motor 2 7 of this embodiment use stepper motors, and the motor 3 8 uses a reduction motor with a self-locking function, which can match the test requirements under different wear-resistant test conditions and realize a more flexible and wider wear-resistant test of the webbing.

It should be noted that the control of stepper motors and reduction motors belongs to the prior art, and the present utility model does not improve it, so this article will not discuss it further.

The wear-resistant test roller 4 of this embodiment includes a roller body 41, a mounting cylinder 42 and a positioning ring 43. The roller body 41 is fixedly connected to the driving shaft of the motor 38, the mounting cylinder 42 is sleeved in the roller body 41, a test paper 44, such as sandpaper, is fixed on the surface of the mounting cylinder 42, and the two ends of the mounting cylinder 42 are screwed with positioning rings 43 for positioning the mounting cylinder 42. When the webbing 5 passes on the surface of the test paper 44, the friction of the test paper 44 on the webbing 5 realizes the wear resistance test of the webbing 5.

In order to prevent the position of the webbing 5 on the wear-resistant test roller 4 from being offset, a positioning ring groove 45 for positioning the webbing 5 is formed between the positioning ring 43 and the test paper 44 in this embodiment.

In addition, in order to allow the webbing 5 to effectively enter the positioning ring groove 45, the edges of the two positioning rings 43 of this embodiment that are close to each other are both provided with chamfered structures.

The working principle of the utility model is: fix the two ends of the webbing 5 to be tested on the winding rollers respectively, then start one of the stepper motors, such as motor 16, to wind up the webbing 5 through the winding roller 12 to achieve the installation of the webbing 5. After the webbing 5 is wound and installed, it is necessary to ensure that the webbing 5 is wound on the test paper 44 of the wear-resistant test roller 4.

During the test, only another stepper motor is powered on, such as motor 27, and the reel 23 is used to reel the webbing 5. At this time, since motor 16 is not powered on, the reel 2 freely rotates and unwinds the webbing 5 under the reeling action of motor 27 on the webbing 5. When the webbing 5 passes through the test paper 44, the webbing 5 can be rubbed. When motor 27 has finished reeling the webbing 5, motor 27 is powered off, and motor 16 is powered on, and the webbing 5 is reeled through reel 2, so that the webbing 5 passes through the test paper 44 again for the wear test. This process is repeated, and when the test reaches the predetermined time, the wear test of the webbing 5 is completed.

During the test, the motor 3 8 can make the wear-resistant test roller 4 stationary or rotating as required.

The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
