Description

Technical Field

[0001] The invention relates to the technical field of textile fabric testing, in particular to wear resistance testing equipment for textile fabrics. Background Art

[0002] After the fabric is produced, it can be made into clothes or other textiles. However, in order to ensure the quality and service life of the fabric, the fabric will be tested for wear resistance before processing. Usually people hold the fabric in their hands and test it on a sanding block. People need to move the fabric constantly. After a long time, people are easily tired, resulting in low test efficiency, and the subsequent test intensity is inconsistent, which can easily affect the accuracy of the test. Therefore, multiple people are required to work alternately to test the wear resistance of the fabric.

[0003] According to a textile fabric wear resistance testing machine described in Patent No. CN109612861A, when the fabric is fixed during use, different stretching forces will result in different tightness of the fabric. When the friction is large, the fabric needs to be tightened to prevent it from falling off. At this time, the degree of opening of the fabric is different, which will affect the contact strength with the test equipment. When the friction is greater, it is necessary to increase the pulling force on both sides of the fabric to ensure sufficient contact with the test equipment to prevent affecting the normal detection effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a wear resistance testing device for textile fabrics, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a wear-resistant testing device for textile fabrics, comprising a test bench and a side plate fixed to one side of the test bench, a limiting component for limiting the fabric is arranged on the surface of the side plate, a friction component for rubbing the fabric is arranged on the top of the test bench, and a collecting component for collecting debris is arranged in the inner cavity of the test bench;

[0006] The limiting assembly includes two upper pressure plates and a lower pressure plate that slide up and down through the surface of the side plate driven by a cylinder, the two upper pressure plates are arranged above the lower pressure plate, and the two sides of the upper pressure plates away from each other are slidably connected to an upper moving block through a sliding rod, the sliding rod is located in an inner cavity of the upper pressure plate and is provided with a return spring fixedly connected to one side of the upper moving block, both sides of the lower pressure plate are slidably connected to a lower moving block located below the upper moving block through a guide rod, the cloth is arranged between the upper moving block and the lower moving block, one side of the upper moving block is fixedly connected to an upper sleeve ring, and the top of the lower moving block is fixedly connected to a positioning rod slidably connected to the inner cavity of the upper sleeve ring;

[0007] The top of the test bench is fixedly connected with an upper push block, and the top of the test bench is fixedly connected with a lower push block, and parallel cross-sections are opened on the opposite sides of the lower push block and the upper push block. When in use, the cloth to be tested is first placed on one side of the lower pressing plate, and then the upper pressing plate on the right is driven to move downward and squeeze above the lower pressing plate to fix one end of the cloth, and then the other end of the cloth is pulled to the other side, and it is straightened by hand, and then the upper pressing plate on the left is driven to move downward, and the cloth is squeezed into the square groove through the setting of the square block, thereby increasing the friction force between the cloth and the upper and lower moving blocks, which can effectively prevent the cloth from falling off. Through the segmented descending setting of the two upper pressing plates, first, one end of the cloth is fixed by descending one upper pressing plate, and then the other end of the cloth is pulled to the bottom of the other upper pressing plate. At this time, the cloth is squeezed by pressing downward on the other upper pressing plate to complete the limiting, and the two square blocks move downward into the square groove. At this time, the squeezed cloth is bent downward, which can pull The cloth is moved so that it remains in a taut state, so that the cloth can be quickly fixed and straightened, and the cloth can be prevented from not being in contact with the friction component due to not being straightened, and the friction test can not be effectively carried out. After the cloth is fixed, the two upper pressing plates and the lower pressing plate are driven to descend at the same time, and the cloth is synchronously driven to move downward to contact with the friction belt, and then the friction belt is rotated to carry out the friction test, and when the lower pressing plate descends, the cross-sections between the upper push block and the lower push block contact each other, and then the lower push block pushes the upper push block to make it move to the left when it descends. At this time, the lower moving block slides to the left on the guide rod and drives the upper moving block to stretch the reset spring to move to the left through the positioning rod, and drives the cloth to open while descending, and can automatically adjust the pulling force on the cloth according to the contact strength with the friction belt, and can automatically pull the cloth apart when the friction force is large to prevent it from being unable to be tested normally due to the inability to be effectively tightened due to elasticity, and can be adaptively adjusted according to the friction force, and the test effect is better.

[0008] As a further solution of the present invention: a square block is fixedly connected to the bottom of the upper moving block, and a square groove adapted to the surface of the square block is opened on the top of the lower moving block. The cloth is squeezed into the square groove through the setting of the square block, thereby increasing the friction between the cloth and the upper moving block and the lower moving block, which can effectively prevent the cloth from falling off.

[0009] As a further solution of the present invention: there are two upper pressing plates, and they are driven by different driving cylinders respectively. When the two upper pressing plates are flush, they are assembled into a complete pressing plate. Through the segmented descending setting of the two upper pressing plates, one end of the cloth is first fixed by descending one upper pressing plate, and then the other end of the cloth is pulled to the bottom of the other upper pressing plate. At this time, the cloth is squeezed by pressing down on the other upper pressing plate to complete the limiting, and moves downward into the square groove through two square blocks. At this time, the squeezed cloth bends downward, which can pull the cloth to keep it in a taut state, so that the cloth can be quickly fixed and can be quickly straightened, which can prevent the cloth from not contacting the friction component due to not being straightened, and the friction test cannot be effectively carried out.

[0010] As a further solution of the present invention: the friction assembly includes a friction belt arranged above the test bench and driven by a power mechanism, and the plane on the top of the friction belt contacts the bottom of the cloth to increase the friction area, and the contact area with the cloth can be increased by rotating the friction belt.

[0011] As a further solution of the present invention: a groove is provided on one side of the lower pressing plate. When the lower pressing plate is lowered to the lowest position, the friction belt is located in the inner cavity of the groove. The setting of the groove will not interfere with the normal lifting process of the lower pressing plate.

[0012] As a further solution of the present invention: the collecting component includes a collecting tank arranged in the inner cavity of the test bench, the inner cavity of the collecting tank is connected to the external negative pressure mechanism, the inner cavity of the collecting tank is slidably connected with a filter, the surface of the test bench is provided with an exhaust port connected to the collecting tank, the exhaust port is arranged between the lower pressure plate and the lower moving block, and when in use, negative pressure is applied in the collecting tank through the negative pressure mechanism, and debris generated after friction of the friction belt is drawn into the collecting tank through the exhaust port for centralized collection, and the setting of the filter can prevent it from being adsorbed by the negative pressure mechanism.

[0013] As a further solution of the present invention: a sliding seal on one side of the test bench is provided with a pull rod which penetrates and extends to the inner cavity of the collection tank, one end of the pull rod is fixedly connected to one side of the filter screen, and one end of the pull rod located on the outer side of the test bench is fixedly connected to a connecting block, and a cleaning door connected to the inner cavity of the collection tank is provided on the surface of the test bench. When in use, after a certain amount of debris is collected, the connecting block is pulled to drive the pull rod to move, and the debris is pushed to the side through the filter screen, and then the cleaning door is opened to take out the debris for cleaning.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can quickly fix the fabric and straighten it quickly to prevent the fabric from not being in contact with the friction component due to not being straightened, and thus failing to effectively conduct the friction test. The pulling force on the fabric is automatically adjusted according to the contact force with the friction belt, and the fabric can be automatically pulled apart when the friction force is large to prevent the fabric from failing to be tested normally due to the inability to effectively tighten the elasticity. The test effect is better due to the adaptive adjustment according to the friction force.

[0016] 2. The present invention squeezes the cloth into the square groove by setting the square blocks, thereby increasing the friction between the cloth and the upper moving block and the lower moving block, and can effectively prevent the cloth from falling off.

[0017] 3. When the present invention is in use, after a certain amount of debris is collected, the connecting block is pulled to drive the pull rod to move, and the debris is pushed to the side through the filter screen, and then the cleaning door is opened to take out the debris for cleaning.

[0025] The limiting assembly includes two upper pressing plates 3 and a lower pressing plate 4 which slide up and down on the surface of the side plate 2 driven by a cylinder. The two upper pressing plates 3 are arranged above the lower pressing plate 4. The two sides of the two upper pressing plates 3 which are away from each other are slidably connected to an upper moving block 7 through a sliding rod 6.
