Description

Technical Field

[0001] The utility model relates to the technical field of fabric abrasion resistance detection, in particular to a device for detecting the abrasion resistance of a knitted composite fabric that is convenient to fix. Background Technique

[0002] In the textile industry, as a key material widely used, the quality inspection of knitted composite fabrics is an important link to ensure product quality. Among them, the abrasion resistance, as one of the important indicators to measure the fabric quality, is directly related to the durability and service life of the product for consumers.

[0003] However, in the existing technology, the detection of the abrasion resistance of knitted composite fabrics mainly relies on the grinding method. This method usually places the fabric on the operating table and then directly simulates physical wear on it through a grinding disc. Due to the relatively simple traditional fixing method, it often fails to provide sufficient stability, resulting in the fabric being prone to relaxation and slippage during the grinding process. This not only seriously affects the accuracy and reliability of the grinding experiment, leading to poor accuracy of test data, but also increases the operation difficulty and reduces the detection efficiency.

[0026] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0027] Please refer to Figures 1 to 7 For achieving the above object, the present utility model provides the following technical solutions:

By adjusting the position of the movable plate 304, the distance between the upper clamping plate 305 and the lower clamping plate 302 can be flexibly adjusted to adapt to fabrics of different thicknesses; first support plates 4 and second support plates 5 are respectively arranged on the outer sides of the two long sides of the detection table 2, and the first support plate 4 and the second support plate 5 are respectively fixedly connected to the outer side walls of the detection table 2; a grinding component 6 is arranged above the detection table 2, and both sides of the grinding component 6 are respectively movably connected to the first support plate 4 and the second support plate 5, thus allowing the grinding component 6 to move in the horizontal direction so as to grind different positions of the fabric.

[0029] Please refer to Figure 2 、 Figure 3 As an embodiment of the present utility model, a telescopic cylinder 306 is arranged at the upper end of the support frame 303, and the cylinder body of the telescopic cylinder 306 is fixedly connected to the upper end of the support frame 303; the top end of the piston rod of the telescopic cylinder 306 is fixedly connected with a hinge groove seat 307, and a first hinge connecting rod 308 is arranged inside the hinge groove seat 307; the upper end of the first hinge connecting rod 308 is hinged to the hinge groove seat 307 through a pin shaft, and the lower end of the first hinge connecting rod 308 is hinged to the movable plate 304 through a pin shaft; a second hinge connecting rod 309 is arranged at one end of the movable plate 304 away from the first hinge connecting rod 308 above, and the lower end of the second hinge connecting rod 309 is hinged to the movable plate 304, and the upper end of the second hinge connecting rod 309 is hinged to the bottom of the support frame 303, and a linkage rod 310 is arranged between the first hinge connecting rod 308 and the second hinge connecting rod 309.

[0030] In the above-described solution, the telescopic cylinder 306 is installed at the upper end of the support frame. The telescopic cylinder 306 provides a power source for the entire fabric fixing assembly 3. The top end of the piston rod of the telescopic cylinder 306 is fixedly connected with a hinge groove seat 307. The upper end of the first hinge connecting rod 308 is hinged to the hinge groove seat 307 through a pin shaft, enabling the first hinge connecting rod 308 to rotate relative to the hinge groove seat 307. The lower end of the first hinge connecting rod 308 is also hinged to the movable plate 304 through a pin shaft. When the piston rod of the telescopic cylinder 306 expands and contracts, the first hinge connecting rod 308 drives the movable plate 304 to move up and down. At the other end above the movable plate 304, there is a second hinge connecting rod 309. The lower end of the second hinge connecting rod 309 is hinged to the movable plate 304, and the upper end of the second hinge connecting rod 309 is hinged to the bottom of the support frame 303. The function of the second hinge connecting rod 309 is to provide a stable support and balance effect to ensure that the movable plate 304 can remain stable when moving up and down. A linkage rod 310 is provided between the first hinge connecting rod 308 and the second hinge connecting rod 309. The function of the linkage rod 310 is to ensure that the first hinge connecting rod 308 and the second hinge connecting rod 309 can move synchronously during operation, thereby maintaining the smooth movement of the movable plate 304.

[0031] When it is necessary to adjust the fixing degree of the fabric, the piston rod of the telescopic cylinder 306 is controlled to expand and contract, so that the piston rod drives the hinge groove seat 307 and the first hinge connecting rod 308 to move, and then drives the movable plate 304 to move up and down. The second hinge connecting rod 309 and the linkage rod 310 work together to ensure that the movable plate 304 remains stable during movement and at the same time provide a stable supporting force for the upper clamping plate 305. Furthermore, the distance between the upper clamping plate 305 and the lower clamping plate 302 can be accurately adjusted to adapt to knitted composite fabrics of different thicknesses and types, ensuring that the fabric can remain flat and stable during the detection process.

[0032] Please refer to Figure 3 As an embodiment of the present invention, a plurality of support shafts 311 are provided between the upper clamping plate 305 and the movable plate 304. The lower end of the support shaft 311 is fixedly connected to the upper clamping plate 305, and the upper end of the support shaft 311 is movably connected to the movable plate 304. The movable plate 304 is provided with a plurality of flange linear bearings 312 adapted to the support shafts 311. The support shafts 311 pass through the flange linear bearings 312 and are movably connected thereto. A linear spring 313 is sleeved on the outer wall of the support shaft 311. The upper end of the linear spring 313 is fixedly connected to the movable plate 304, and the lower end of the linear spring 313 is fixedly connected to the upper clamping plate 305. Guide sleeves 314 are respectively provided at both ends of the movable plate 304. A guide rod 315 is slidably connected in the guide sleeve 314. The upper end of the guide rod 315 is fixedly connected to the inner wall of the support frame 303 through a connecting plate 316, and the lower end of the guide rod 315 is fixedly connected to the bottom plate 301.

[0033] In the above-described solution, the support shaft 311 is disposed between the upper clamping plate 305 and the movable plate 304, and is used to support the upper clamping plate 305 and allow it to move in the vertical direction. The lower end of the support shaft 311 is fixedly connected to the upper clamping plate 305 to ensure that the upper clamping plate 305 and the support shaft 311 remain synchronized during the movement. A plurality of flange linear bearings 312 adapted to the support shaft 311 are provided on the movable plate 304. The support shaft 311 passes through the flange linear bearings 312 and slides linearly therein to reduce the friction with the movable plate 304 and ensure that the upper clamping plate 305 can move smoothly up and down. By sleeving a linear spring 313 on the outer wall of the support shaft 311, the linear spring 313 is used to provide damping and reset functions for the upper clamping plate 305 during movement. The upper end of the linear spring 313 is fixedly connected to the movable plate 304, and the lower end is fixedly connected to the upper clamping plate 305. When the upper clamping plate 305 is subjected to an external force, the linear spring 313 will be compressed; when the external force disappears, the linear spring 313 will release energy to help the upper clamping plate 305 reset. Guide sleeves 314 are provided at both ends of the movable plate 304, and guide rods 315 are slidably connected inside the guide sleeves 314. The upper end of the guide rod 315 is fixedly connected to the inner wall of the support frame 303 through a connecting plate 316, and the lower end of the guide rod 315 is fixedly connected to the bottom plate 301, thereby forming a stable guiding structure to ensure that the movable plate 304 can remain horizontal during up and down movement and will not tilt or shake.

[0034] When it is necessary to adjust the position of the upper clamping plate 305, the piston rod of the telescopic cylinder 306 will extend or retract, thereby driving the movable plate 304 to move up and down. During the movement of the movable plate 304, the guide rod 315 slides inside the guide sleeve 314 to provide a stable guiding function; at the same time, the support shaft 311 slides inside the flange linear bearing 312 to reduce the friction with the movable plate 304, and the linear spring 313 expands and contracts on the outer wall of the support shaft 311 to provide damping and reset functions for the upper clamping plate 305. This design ensures the smoothness and accuracy of the upper clamping plate 305 during the adjustment process, so as to accurately fix knitted composite fabrics of different thicknesses and provide reliable support for wear resistance detection.

A first sliding seat 604 is fixedly connected to the other end of the connecting member 603, and the first sliding seat 604 provides stable support and guidance for the grinding assembly 6; by arranging the first limit guide rail 605 side by side on one side of the magnetic coupling rodless cylinder 601, the first limit guide rail 605 is used to limit and guide the movement of the first sliding seat 604. A first guide rail slider 606 adapted to the first limit guide rail 605 is provided at the bottom of the first sliding seat 604, and the first guide rail slider 606 slides on the first limit guide rail 605 to ensure that the first sliding seat 604 moves horizontally along a predetermined path; by installing the second limit guide rail 607 on the second support plate 5, a second sliding seat 608 is provided above the second limit guide rail 607, and a second guide rail slider 609 adapted to the second limit guide rail 607 is provided at the bottom of the second sliding seat 608.

[0037] When the wear resistance test is required, the magnetic coupling rodless cylinder 601 is started to drive its movable cylinder 602 to move horizontally. The movement of the movable cylinder 602 is transmitted to the first sliding seat 604 through the connecting piece 603, driving the first sliding seat 604 to slide on the first limit guide rail 605. At the same time, the second sliding seat 608 will also slide correspondingly on the second limit guide rail 607. Through the cooperation of the first sliding seat 604 and the second sliding seat 608, the grinding assembly 6 can move horizontally along a predetermined path, so as to perform grinding tests on different positions of the fabric, ensuring the stability and accuracy of the grinding assembly 6 during the test, and effectively improving the accuracy and reliability of the wear resistance detection of the fabric.

When the first ball screw 611 rotates, the first sliding seat 604 is driven to perform linear movement through the rolling of the balls; the structure of the second ball screw 612 is the same as that of the first ball screw 611. The upper end of the second ball screw 612 penetrates through the support plate 610 and is fixedly connected to the support plate 610 through the third bearing seat 9, and the lower end of the second ball screw 612 is connected to the second sliding seat 608 through the fourth bearing seat 10. The second ball screw 612 also drives the second sliding seat 608 to perform linear movement through the rolling of the balls; by controlling the rotation of the first ball screw 611 and the second ball screw 612 by the servo motor 11, the rotational motion is converted into a linear motion. This rolling friction has higher efficiency and longer service life compared with sliding friction. Through the rolling of the balls, the first ball screw 611 drives the first sliding seat 604 to perform linear movement, and the second ball screw 612 drives the second sliding seat 608 to perform linear movement, so as to ensure that both ends of the grinding assembly 6 can move synchronously and accurately, ensuring the stability and uniformity of the grinding process, and improving the grinding quality and efficiency.
