Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of textile detection, and more particularly to a textile friction detection device and a textile friction detection method. Background Art
[0002] During the textile friction testing process, the surface of the textile needs to be polished by a specific friction part, and the driver is used to drive the action so that the friction part can continuously rub the surface of the textile for a long time, and then observe the state of the textile after friction treatment to obtain the friction performance of the textile.
[0003] During friction testing, textiles are typically cut into discs and clamped onto a support disc using a clamping device. Supported by the disc, the top of the textile remains flat. A friction assembly is mounted on the top of the disc. The friction element abuts against the top of the textile, exerting a certain distance on the textile and generating friction during movement. During testing, the disc is often rotated axially, causing rotational abrasion between the textile on the disc and the friction element, ultimately polishing and wiping the textile.
[0004] However, this type of testing often only allows for one set of friction elements to be installed on the upper side of the textile being tested. Using multiple sets of control elements often requires multiple sets of testing equipment, making testing inconvenient. Furthermore, if multiple sets of friction elements are installed simultaneously on the upper side of the textile, each set of friction elements will have a different distance from the textile's rotation center. Even with the same number of rotations, each friction element will abrade the textile at a different distance. Therefore, simultaneous abrasion of multiple sets of friction elements is impossible.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] This embodiment discloses a textile friction detection device, such as Figure 1 、 2 As shown, it includes a support roller 1 and several friction components. The support roller 1 is arranged horizontally. A rotating shaft 2 is fixed at the middle axis position of the support roller 1. Both ends of the rotating shaft 2 are installed on the frame 4 through bearings; the rotating shaft 2 is connected to the output shaft of the rotary drive through a coupling, and then the rotary drive can drive the rotating shaft 2 and the support roller 1 to rotate.
[0038] The outer periphery of the support roller 1 is covered with the textile to be tested. The textile is wound in a circumferential direction and maintained in a flat state, so that the textile to be tested 11 is in flat contact with the outer peripheral surface of the support roller 1. The friction assembly is located on the upper side of the support roller 1. Each set of friction assemblies has a friction wheel 5. During testing, the lower side of the friction wheel 5 is pressed against the upper side of the support roller 1, rubbing the textile to be tested 11 on the outer periphery of the support roller 1. The support roller 1 is rotated by a rotary drive, thereby generating friction between the test textile and the friction wheel 5, and testing the friction performance of the textile. The friction assemblies are arranged along the axial direction of the support roller 1, forming multiple friction detection positions on the upper side of the support roller 1, which can simultaneously obtain multiple sets of friction parameters.
[0039] After the friction test, the textile is removed from the periphery of the support roller 1, and the textile after friction is observed according to the parameter requirements of the textile to be tested, and the required conditions are recorded, such as whether the textile is worn through, the size of the holes caused by friction, and the color change after friction, etc.
[0040] According to different friction requirements, friction rollers with different pressures and friction coefficients are set for each group of friction components, so that multiple groups of performance parameters with different friction effects can be achieved at the same time. In addition, since the same support roller 1 is used for rotational drive, it is beneficial to control the blocking of mutual friction sliding during the friction detection process, which is beneficial to control various parameter variables.
[0041] like Figure 2 As shown, the friction assembly includes a support rod 3, a friction wheel 5 and a counterweight 31. One end of the support rod 3 is rotatably connected to the frame 4, so that the other end of the support rod 3 extends to the upper side of the support roller 1 and can be swung up and down for adjustment.
[0042] A friction wheel 5 is mounted on the side of the support rod 3, away from the rotating end. This wheel can swing up and down with the support rod 3 and press against the upper side of the support roller 1, rubbing the textile outside the roller 1. The gravity of the friction wheel 5 and other components applies a certain amount of pressure to the textile, enabling friction detection. To adjust the pressure, counterweights 31 can be installed at the far end of the support rod 3, away from the rotating end. By adjusting the number of counterweights 31, the pressure between the friction wheel 5 and the textile can be adjusted, thereby creating different friction effects and adjusting the friction detection parameters.
[0043] like Figure 3-5 As shown, a receiving groove 6 is provided on the periphery of one side of the support roller 1. The receiving groove 6 has an opening 61 facing the periphery of the support roller 1. The opening 61 extends along the axial direction of the support roller 1 and forms a strip-shaped structure. An adjusting roller assembly 8 is installed in the receiving groove 6, parallel to the support roller 1.
[0044] Adjusting roller assembly 8 connects to the textile to be inspected 11, which is wound around its periphery. One side of adjusting roller assembly 8 protrudes from opening 61 by a certain height, typically 1-3 mm, above the outer contour of support roller 1. During rotation of support roller 1, the side of adjusting roller assembly 8 corresponding to opening 61 is subjected to friction from friction wheel 5. Force is transmitted between the two sides through the textile to be inspected 11, driving a slight rotation of adjusting roller assembly 8. During this rotational adjustment process, the textile is reeled in, maintaining tension around the outer periphery of support roller 1.
[0045] Because textiles often have a certain degree of elasticity, the friction wheel 5 is constantly stretched in a unilateral direction during the friction process. After a long period of testing, the textile may be slightly stretched, causing the textile, which was originally flatly wound around the periphery of the support roller 1, to become somewhat loose. This may form wrinkles around the periphery of the support roller 1, affecting the detection effect of textile friction. The slightly rotatable adjustment roller group 8 provides additional stretching to the textile 11 to be tested, thereby maintaining the textile in a flat state during the test process, ensuring a stable test process and improving the accuracy of friction detection to a certain extent.
[0046] The two ends of the textile to be inspected 11 need to be fixed in the internal position of the receiving groove 6. To facilitate installation, a notch 62 can be formed on one side of the opening 61 of the support roller 1, and a stopper 7 is installed at the notch 62. The outer periphery of the stopper 7 forms an arc surface that adapts to the support roller 1, forming a mutually assembled structure. The stopper 7 is installed with bolts, which is convenient for disassembly and installation of the stopper 7 and also convenient for installing the textile.
[0047] like Figure 5 As shown, a clamping piece 71 is installed on the inner side of the stopper 7 facing the receiving groove 6. The clamping piece 71 is assembled and disassembled by bolts and can clamp and fix the first end 111 of the textile to be inspected 11 in the inner position of the receiving groove 6. Figure 4 、 5 As shown, when the textile to be inspected 11 is installed, the first end 111 is fixed to the stopper 7 by the clamping piece 71, and then the textile to be inspected 11 extends from the cloth guide gap 72 between the stopper 7 and the adjusting roller group 8, and is wound around the support roller 1 in a counterclockwise direction, that is, in the direction away from the adjusting roller group 8. Then, the second end 112 of the textile to be inspected 11 is again extended into the cloth guide gap 72, and the second end 112 is fixed outside the adjusting roller group 8. By rewinding the adjusting roller group 8, the second end 112 is wound and fixed on the outer periphery of the adjusting roller group 8, so that the textile to be inspected 11 can be flatly wrapped on the outer periphery of the support roller 1.
[0048] A slot 86 is defined on the outer periphery of the rotating drum 83, and a clamping block 87 is mounted within the slot 86. The outer periphery of the clamping block 87 conforms to the outer periphery of the rotating drum 83. Once installed, the clamping block 87 fits into the slot 86, forming a complete outer periphery with the outer periphery of the rotating drum 83. The clamping block 87 is installed using bolts. The end of the textile fits between the slot 86 and the clamping block 87, securing the textile and connecting it to the outer periphery of the rotating drum 83.
[0049] like Figure 5 、 6As shown in Figures 8 and 8, the adjustment roller assembly 8 includes a support shaft 81 and a rotating cylinder 83. The support shaft 81 is installed parallel to the support roller 1, and the two ends of the support shaft 81 are installed at the two ends of the accommodating groove 6. The rotating cylinder 83 is sleeved on the outer periphery of the support shaft 81 in a coaxial state to achieve rotational support.
[0050] like Figure 8 As shown, the rotating cylinder 83 is sleeved on the outer periphery of the support shaft 81, and end covers 84 are fixed at both ends of the rotating cylinder 83. The support shaft 81 passes through the end covers 84 on both sides, and is rotatably supported by bearings between the end covers 84 and the support shaft 81 to ensure that the rotating cylinder 83 can rotate smoothly.
[0051] The support rollers 1 and 1 maintain rotation restrictions to form a stable support; a one-way mechanism 9 is installed between the rotating cylinder 83 and the support shaft 81 to keep the rotating cylinder 83 unidirectionally rotatable, and the rotation direction of the rotating cylinder 83 is opposite to that of the support roller 1. The rotating cylinder 83 can be rotated and reeled, and the textile can be tightened, and the textile to be inspected 11 can be stably clamped outside the support roller 1.
[0052] like Figure 8 As shown, a cylindrical support column 82 is fixedly connected to the outer periphery of the support shaft 81 at a position corresponding to the inner cavity of the rotating cylinder 83. An annular gap 85 is formed between the support column 82 and the rotating cylinder 83. The one-way mechanism 9 is installed between the support column 82 and the rotating cylinder 83, thereby maintaining the one-way rotation of the rotating cylinder 83 and the support shaft 81, thereby enabling the rotating cylinder 83 to rewind the textile without reversing and causing the textile to loosen. Specifically, the one-way mechanism 9 can be a one-way ratchet mechanism, which is unidirectionally linked through the ratchet teeth and ratchet grooves in the ratchet mechanism, and can only maintain the forward rotation of the rotating cylinder 83 around the rotating shaft 2, and can limit the reverse rotation of the rotating cylinder 83, maintaining a stable linkage state between the rotating cylinder 83 and the support shaft 81.
[0053] like Figure 6 、 7 As shown, the one-way mechanism 9 includes a plurality of ratchet members 91 and ratchet grooves 95 that are adapted to each other. The ratchet grooves 95 are arranged in a circular array on the inner periphery of the rotating cylinder 83, forming a circumferentially continuous arrangement. The ratchet members 91 are arranged in a circular array on the outer periphery of the support column 82. One end of the ratchet member 91 is connected to the support column 82, and the other end can be swung and adjusted. Figure 6 、 7When the rotating drum 83 rotates counterclockwise, the ratchet member 91, under the interaction of the ratchet groove 95, can swing inwardly toward the support shaft 81, causing the ratchet member 91 and the ratchet groove 95 to slip against each other, and the rotating drum 83 can rotate forward, thus compensating for the textile outside the rotating drum 83. When the rotating drum 83 rotates reversely, the ratchet member 91 can swing outwardly toward the support shaft 81, and the ratchet member 91 can be embedded in the ratchet groove 95, thereby limiting the reverse rotation of the rotating drum 83 and preventing the textile from being loosened due to the rotation.
[0054] The ratchet member 91 can be adjusted in an elastic swinging or rotational swinging state. For example, the ratchet member 91 can be made of elastic plastic or rubber material and have a sheet-like structure. One end of the ratchet member 91 is connected to the outer periphery of the support column 82, and the other end is tilted toward one side. The ratchet linkage can be achieved by the ratchet groove 95 and the elastic ratchet member 91 being linked to each other.
[0055] Or, as Figure 7 As shown, the ratchet member 91 can be made of hard metal or plastic material. One end of the ratchet member 91 is rotatably connected to the support column 82 through a linkage shaft 92, and the other end forms a ratchet end 94. The ratchet member 91 can be rotated and adjusted around the linkage shaft 92 to achieve an outward swing-open state or an inward controlled state. The ratchet member 91 extends outward from the linkage shaft 92 to form an arc-shaped structure, forming the ratchet end 94. A protrusion 93 is fixed on the side of the support column 82 corresponding to the ratchet member 91. The protrusion 93 can press against the ratchet member 91 to maintain the ratchet member 91 in an outward swing state, so that the ratchet end 94 is embedded in the ratchet groove 95.
[0056] Specifically, if Figure 7 As shown, a flat surface 941 is formed on the right side of the ratchet end 94, and an arcuate surface 942 is formed on the left side; a flat surface 951 is formed on the right side of the swing of the ratchet groove 95, and an inclined surface 952 is formed on the left side. When the rotating cylinder 83 rotates counterclockwise, the inclined surface 952 of the ratchet groove 95 will press against the arcuate surface 942 of the ratchet end 94, pushing the ratchet member 91 to rotate inward. The ratchet end 94 of the ratchet member 91 and the ratchet groove 95 then separate from each other, allowing the two to slip against each other, thereby allowing the rotating cylinder 83 to rotate smoothly. When the rotating cylinder 83 rotates clockwise, the ratchet end 94 of the ratchet member 91 will be embedded in the ratchet groove 95, and the ratchet member 91 will be blocked by the protrusion 93. In order to maintain the state of the ratchet member 91, the plane 1 941 in the ratchet groove 95 and the plane 2 951 of the ratchet end 94 press against each other, thereby maintaining the state in which the rotating sleeve and the support shaft 81 are fixed to each other, preventing the rotating sleeve from rotating and causing the textile outside the rotating cylinder 83 to loosen.
[0057] Moreover, the ratchet parts 91 in the one-way mechanism 9 are generally provided in four to six groups, so that there is always a ratchet part 91 located at the lower side of the axis of the support shaft 81. The ratchet part 91 on the lower side can swing downward under the action of gravity, so that the ratchet end 94 can be embedded in the ratchet groove 95, ensuring that the one-way mechanism 9 can stably realize one-way linkage.
[0058] Furthermore, the structure of the adjusting roller assembly 8 can be further optimized so that the adjusting roller assembly 8 can achieve elastic floating adjustment toward the inside of the accommodating groove 6, thereby maintaining the adjustment friction assembly and the support roller 1, and the adjusting roller assembly 8 can adaptively and elastically float toward the inside of the accommodating groove 6. Due to the different protruding openings 61 of the rotating cylinder 83 of the adjusting roller assembly 8, a protrusion 831 protruding from the opening 61 is formed on the rotating cylinder 83. The protrusion 831 acts as a friction transmission with the friction wheel 5 and the textile. When the textile outside the support roller 1 is slightly loose, the rotating cylinder 83 is subjected to friction, which can form a winding action. By winding the rotating cylinder 83, the textile can be wound and pulled, so that the textile can maintain a stable fit around the outer periphery of the support roller 1. When the textile outside the supporting roller 1 is in a relatively tight state, the rotating cylinder 83 can, under the pressure of the friction wheel 5, slightly float the adjusting roller group 8 toward the inner side of the accommodating groove 6 to overcome the rotation of the rotating cylinder 83 and the slipping caused by the inward movement; through the elastic floating adjustment of the adjusting roller group 8, the textile will not slip during the winding process, thereby avoiding excessive winding and tensioning of the textile around the supporting roller 1.
[0059] like Figure 9 、 10 As shown, chutes 101 are provided at both ends of the inner side of the receiving groove 6. The chutes 101 are arranged along the radial direction of the support roller 1, with one end facing the opening 61. A slider 10 is installed in the chutes 101. The slider 10 and the chutes 101 are slidably connected to each other, allowing the slider 10 to slide and adjust along the radial direction of the support roller 1. Protrusions are provided on both sides of the slider 10, while grooves are provided on both sides of the chutes 101. The slidable fit between the protrusions and the grooves allows the slider 10 to slide relative to each other, maintaining a stable state.
[0060] The two ends of the support shaft 81 are fixedly connected to the sliders 10 on both sides, so that the support shaft 81 and the rotating cylinder 83 on the outer periphery of the support shaft 81 can be radially slidably adjusted, thereby allowing the protrusion 831 of the rotating cylinder 83 to be retracted into the receiving groove 6, thereby forming a floating adjustment to adjust the height of the protrusion 831. In this way, the friction between the rotating cylinder 83 and the friction wheel 5 can be adjusted.
[0061] To elastically support the slider 10 and maintain the elastic floating state of the adjustment roller assembly 8, a spring 102 can be installed between the slider 10 and the end of the slider 10 that faces the axis of the rotating shaft 2. The spring 102 elastically pushes the slider 10, pushing the slider 10 and the adjustment roller assembly 8 outward, so that the protrusion 831 on the outer periphery of the adjustment roller assembly 8 can be stably pressed and frictionally linked with the friction wheel 5. This allows the adjustment roller assembly 8 to elastically float toward the inside of the accommodating groove 6, forming an adaptive elastic floating adjustment. In addition, a screw hole 103 is provided at the end of the slide groove 101, that is, the end facing the outside of the slide groove 101. One end of the screw hole 103 connects to the outer periphery of the support roller 1, and the other end connects to the inside of the slide groove 101. The screw 104 is threadedly connected to the screw hole 103, and the end of the screw 104 extends from the screw hole 103 into the slide groove 101 and abuts against the slider 10; the position of the screw 104 can be adjusted by the threaded screw 104, and then the position of the slider 10 can be adjusted, and then the protrusion of the protrusion 831 of the adjusting roller group 8 can be adjusted, and the friction between the adjusting roller group 8 and the friction wheel 5 can be adjusted by an appropriate protrusion height, so that the two can be kept in rotational linkage, and then the rotating drum 83 can be smoothly rotated and wound, so as to maintain the textile on the periphery of the support roller 1 in a stable wrapped installation state, which is beneficial to textile friction detection.
[0062] This embodiment also discloses a method for detecting friction of textiles, which uses the detection device in the above embodiment to perform detection;
[0063] Cut the textile to be inspected 11 into a rectangular sheet, install the textile to be inspected 11 on the periphery of the support roller 1, and wrap the textile to be inspected 11 around the periphery of the support roller 1 to form a flat and close fit;
[0064] During installation, the block 7 on the outer periphery of the support roller 1 is removed, and the first end 111 is fixed to the block 7 by the clamping piece 71. Then, the textile to be inspected 11 extends from the cloth guide gap 72 between the block 7 and the adjusting roller group 8, and is wound around the support roller 1 in a counterclockwise direction, that is, in the direction away from the adjusting roller group 8. Then, the second end 112 of the textile to be inspected 11 is extended into the cloth guide gap 72 again, and the second end 112 is fixed to the outside of the adjusting roller group 8 by the clamping block 87. By rewinding the adjusting roller group 8, the second end 112 is wound and fixed to the outer periphery of the adjusting roller group 8, so that the textile to be inspected 11 can be flatly wrapped on the outer periphery of the support roller 1.
[0065] Then, swing the support rod 3 of the friction assembly downward, pressing the friction wheel 5 against the upper side of the support roller 1, thereby pressing the textile around the outer periphery of the support roller 1. By adjusting the counterweight 31, the downward pressure of the friction wheel 5 is adjusted to adjust the friction parameters. Multiple different friction assemblies can be pressed against the upper side of the support roller 1 simultaneously, forming a multi-point friction test.
[0066] The rotary drive is activated, rotating the support roller 1 and the textile surrounding it at a set speed. Simultaneously, it cooperates with the friction assembly to perform friction testing on the textile 11 to be tested. During the testing process, the friction assembly causes the adjustment roller assembly 8 to rotate slightly. During this rotational adjustment process, the textile is reeled in, keeping the textile surrounding the support roller 1 flat and in place, preventing stretching and wrinkling, and maintaining stable friction testing.
[0067] After the set time is reached, the textile is removed from the periphery of the supporting roller 1, and the state of the textile is tested to obtain the required friction properties of the textile.
