Description

Technical Field

[0001] This utility model relates to the field of textile material performance testing technology, and in particular to a fabric friction testing device. Background Technology

[0002] In the field of textile material performance testing technology, the abrasion resistance and friction damage resistance of fabrics are key indicators for measuring their quality, especially for the bag manufacturing industry where they have more direct application significance. As everyday items or travel tools, bags and luggage are constantly subjected to continuous and complex friction with the human body, luggage, and outdoor environments such as rocks and branches during use. Examples include the repeated friction between the palm and the bag strap when carrying a bag, the friction between the suitcase and the ground or steps during dragging a rolling suitcase, the friction between the shoulder strap and clothing when carrying a backpack, and the scratching of the bag's lining and placed items such as keys and stationery. These friction scenarios are not only frequent but also vary significantly in magnitude, direction, and contact medium. If the abrasion resistance or friction damage resistance of the fabric used in bags is insufficient, problems such as surface pilling, fiber breakage, coating peeling, and even localized damage are likely to occur in the early stages of use. This not only affects the bag's aesthetics and durability but may also reduce the user experience and product lifespan, ultimately impacting brand reputation and market competitiveness.

[0003] Currently, the industry primarily relies on friction testing devices to test the friction performance of fabrics. The core principle is to fix the fabric under test and drive friction components, such as sandpaper, grinding wheels, or standard friction cloths, to generate relative linear reciprocating motion or rotational friction, simulating friction scenarios in actual use. For example, under light load friction, pilling is likely to occur, while under heavy load friction, holes are likely to appear. However, there is generally a lack of precise control over the contact force between the friction components and the fabric. Insufficient contact force may result in test results that do not reflect the actual friction intensity in use, while excessive contact force may cause unexpected excessive wear, leading to a disconnect between test data and actual usage scenarios. Secondly, friction components are prone to loosening, shifting, or central depression during reciprocating motion due to vibration or uneven tension, resulting in uneven contact areas with the fabric, thus affecting the repeatability and accuracy of test results. Furthermore, some devices' friction components are only compatible with a single material, such as fixed sandpaper, making it difficult to flexibly change the friction medium according to different testing standards, limiting the device's versatility.

This adapts to the testing needs of different fabric materials and quick replacement of different friction plates. At the same time, it ensures that the position of the friction plate remains stable and does not shift during reciprocating motion, significantly improving the accuracy, repeatability, and versatility of the test results, and achieving accurate detection and reliable evaluation of the fabric friction performance.

[0024] In the field of textile material performance testing technology, the abrasion resistance and friction damage resistance of fabrics are key indicators for measuring their quality, especially for the bag manufacturing industry where they have more direct application significance. As everyday items or travel tools, bags and luggage are constantly subjected to continuous and complex friction with the human body, luggage, and outdoor environments such as rocks and branches during use. Examples include the repeated friction between the palm and the bag strap when carrying a bag, the friction between the suitcase and the ground or steps during dragging a rolling suitcase, the friction between the shoulder strap and clothing when carrying a backpack, and the scratching of the bag's lining and placed items such as keys and stationery. These friction scenarios are not only frequent but also vary significantly in magnitude, direction, and contact medium. If the abrasion resistance or friction damage resistance of the fabric used in bags is insufficient, problems such as surface pilling, fiber breakage, coating peeling, and even localized damage are likely to occur in the early stages of use. This not only affects the bag's aesthetics and durability but may also reduce the user experience and product lifespan, ultimately impacting brand reputation and market competitiveness.

[0025] Currently, the industry primarily relies on friction testing devices to test the friction performance of fabrics. The core principle is to fix the fabric under test and drive friction components, such as sandpaper, grinding wheels, or standard friction cloths, to generate relative linear reciprocating motion or rotational friction, simulating friction scenarios in actual use. For example, under light load friction, pilling is likely to occur, while under heavy load friction, holes are likely to appear. However, there is generally a lack of precise control over the contact force between the friction components and the fabric. Insufficient contact force may result in test results that do not reflect the actual friction intensity in use, while excessive contact force may cause unexpected excessive wear, leading to a disconnect between test data and actual usage scenarios. Secondly, friction components are prone to loosening, shifting, or central depression during reciprocating motion due to vibration or uneven tension, resulting in uneven contact areas with the fabric, thus affecting the repeatability and accuracy of test results. Furthermore, some devices' friction components are only compatible with a single material, such as fixed sandpaper, making it difficult to flexibly change the friction medium according to different testing standards, limiting the device's versatility.

[0026] Therefore, such as Figures 1 to 3As shown, the fabric friction testing device proposed in this utility model includes a base 100, a fixing component 200 disposed on the base 100, and a friction component 300 disposed on the base 100. The base 100 is provided with a feeding channel 101 for the fabric 400 to extend into, the fixing component 200 is used to fix the fabric 400, and the friction component 300 is disposed on the base 100 and located above the feeding channel 101. Specifically, the friction assembly 300 includes a driving component and a friction component 310. The driving component is used to drive the friction component 310 to reciprocate linearly. Further, the friction component 310 includes a sliding seat 311, a friction plate 312, a pressing column 313, and an adjusting column 314. The friction plate 312 is wound around the sliding seat 311. There are two pressing columns 313, which respectively press and fix the two ends of the friction plate 312. The adjusting column 314 is threaded to the sliding seat 311 in the vertical direction. The adjusting column 314 can press down on the middle of the friction plate 312 to adjust the contact force between the friction plate 312 and the fabric 400. It should be noted that the feeding channel 101 on the base 100 and the fixing component 200 form a compact cloth 400 fixing structure, which can firmly fix the cloth 400 in the test area, prevent displacement and loosening during the test, and ensure concentrated and effective friction. Furthermore, the driving component drives the friction component 310 to reciprocate linearly, realistically simulating the relative friction between the cloth 400 and the object in actual use. Additionally, the sliding seat 311 supports the friction plate 312, and the two side pressing columns 313 press against and fix the two ends of the friction plate 312 to make it fit against the sliding seat 311. The adjusting column 314 is threaded vertically and presses downward against the center of the friction plate 312. By rotating the adjusting column 314, the contact force between the friction plate 312 and the fabric 400 can be precisely adjusted, solving the problem of non-adjustable contact force or low adjustment accuracy of traditional devices. It is suitable for testing needs of different fabric materials 400 and quick replacement of different friction plates 312. At the same time, it ensures that the position of the friction plate 312 is stable and does not shift during reciprocating motion, which significantly improves the accuracy, repeatability and versatility of test results, and realizes accurate detection and reliable evaluation of the friction performance of the fabric 400.

[0027] Refer to Figures 1 to 3In some embodiments of this utility model, the clamping column 313 laterally pushes against the friction plate 312 to drive the friction plate 312 to press against the sliding seat 311. This lateral force ensures that the friction plate 312 is tightly fitted to the surface of the sliding seat 311, preventing loosening or displacement of the friction plate 312 in the vertical or movement direction. It is understood that the lateral pushing method is adapted to the winding state of the friction plate 312, ensuring that the friction plate 312 is uniformly stressed in the circumferential direction. Therefore, when the driving component drives the sliding seat 311 in linear reciprocating motion, the friction plate 312 can maintain stable contact with the sliding seat 311, preventing wrinkles or misalignment caused by insufficient local tension. This improves the uniformity of contact between the friction plate 312 and the fabric 400, providing a stable structural basis for subsequent precise adjustment of the contact force. Simultaneously, it reduces testing errors caused by loosening of the friction plate 312, ensuring the reliability of the test results. Specifically, connecting brackets 3111 are fixedly installed on both sides of the sliding seat 311, and two clamping columns 313 are arranged opposite each other. The clamping columns 313 are screwed to the connecting brackets 3111 one by one to push the friction plate 312 to press the sliding seat 311. The connecting brackets 3111 provide a stable mounting base for the clamping columns 313, so that the lateral pushing force of the clamping columns 313 can be evenly transmitted to both ends of the friction plate 312. In addition, the opposing clamping columns 313 form a symmetrical clamping structure to ensure that the friction plate 312 is subjected to balanced force in the width direction, avoiding deformation or displacement caused by excessive force on one side. Furthermore, the screwed connection method allows the magnitude of the pushing force to be precisely adjusted by rotating the clamping columns 313, thereby adapting to friction plates 312 of different thicknesses or rigidities, and further enhancing the fit stability between the friction plate 312 and the sliding seat 311. Optionally, the friction pad 312 can be made of white paper, kraft paper, or sandpaper, providing a variety of optional materials to adapt the device to different testing needs and standards. For example, white paper is suitable for simulating gentle friction scenarios, such as the slight scratching of a bag lining against an item; kraft paper can simulate medium-intensity friction, such as the contact between fabric 400 and clothing in daily use; and sandpaper is suitable for high-intensity abrasion testing, such as simulating friction against rough surfaces or sharp objects. It should be noted that friction pads 312 of different materials can be quickly replaced and adjusted by being wound around the sliding seat 311 and fixed in conjunction with the clamping column 313 and adjusting column 314. This expands the applicability of the device, allowing the same device to cover a variety of friction conditions from slight to severe, providing comprehensive testing support for the abrasion resistance of fabric 400 in different usage scenarios, and enhancing the versatility and practicality of the device.

[0028] Refer to Figure 3In some embodiments of this utility model, the adjusting column 314 is provided with a spherical portion 3141, which is located at the bottom end of the adjusting column 314 and pushes downward against the upper surface of the friction plate 312. The spherical surface of the spherical portion 3141 serves as the direct contact surface with the friction plate 312, which can evenly distribute the downward pressure applied by the adjusting column 314 and avoid local stress concentration caused by the bottom end of the adjusting column 314 being flat or sharp, thereby preventing the friction plate 312 from denting or breaking due to uneven force. In addition, the design of the spherical portion 3141 allows the adjusting column 314 to adaptively adjust the contact point through the arc-shaped surface during the rotation adjustment process, even if there is a slight offset in the contact position with the friction plate 312, maintaining a stable transmission of downward pressure to the center of the friction plate 312.

[0029] Reference Figure 1 Optionally, the sliding seat 311 is square, with a more regular structure, facilitating processing, manufacturing, and assembly. Simultaneously, the flat outer surface of the square structure provides a smooth support surface for the friction plate 312, ensuring that the friction plate 312, after being wound, can tightly conform to the surface of the sliding seat 311, reducing wrinkles or loosening of the friction plate 312 caused by uneven support surfaces. Specifically, refer to... Figure 3 The lower corners of the sliding seat 311 are all rounded structures 31101, so that the friction plate 312 can smoothly fit the corners of the sliding seat 311, avoiding the sharp edges of the sliding seat 311 from cutting or wearing the friction plate 312, and preventing the friction plate 312 from being locally damaged or stress concentrated due to the corner compression during winding or movement.

[0030] like Figures 1 to 3 As shown, in some embodiments of this utility model, there are two fixing components 200, which are respectively disposed on both sides of the sliding seat 311 to fix the fabric 400 on both sides. It can be understood that the double-sided fixing structure can uniformly constrain the lateral displacement of the fabric 400 in the test area, preventing the fabric 400 from shifting or curling due to the tension or vibration of the reciprocating motion during friction, ensuring that the contact area between the fabric 400 and the friction plate 312 remains stable. Furthermore, the relative positional relationship between the two fixing components 200 and the sliding seat 311 allows the fabric 400 to naturally unfold below the friction plate 312, ensuring that the frictional action is concentrated in the target area and avoiding test errors caused by wrinkles or misalignment of the fabric 400. Specifically, the fixing component 200 includes a fixing bracket 210 and a fixing post 220. The fixing post 220 is threadedly connected to the fixing bracket 210 in the vertical direction to press the upper surface of the fabric 400. It should be noted that the fixed post 220 connected by threads can precisely adjust the clamping force to adapt to different thicknesses or materials of fabrics 400, such as thin nylon or thick canvas, to avoid the fabric 400 being not firmly fixed due to insufficient clamping force or deformed due to excessive clamping force.

[0031] Optionally, in some embodiments of this utility model, the driving component includes a drive motor, a lead screw, and a lead screw nut that are sequentially connected in a transmission relationship. (Refer to...) Figure 1 The sliding seat 311 is fixedly connected to a connecting shaft 3112, which is slidably mounted on the base 100 in the horizontal direction. A lead screw and nut are connected to the connecting shaft 3112 and drive both the connecting shaft 3112 and the sliding seat 311 to move in the horizontal direction. The transmission structure of the lead screw and nut converts the rotational motion of the drive motor into the linear reciprocating motion of the sliding seat 311, featuring high transmission accuracy and smooth movement. It can precisely control the moving speed and displacement of the friction component 310, simulating friction scenarios of different frequencies and amplitudes in actual use. It should be noted that the transmission structure of the motor, lead screw, and lead screw nut can refer to conventional linear modules or commonly available transmission structures on the market, and will not be elaborated upon here.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
