Description

Technical Field

[0001] The present invention relates to the technical field of textile fabric detection, and in particular to a device for detecting mechanical properties of textile fabric. Background Art

[0002] Modern textile technology is a multi-scale structural processing technology for fibers or fiber assemblies. The properties of the final finished fabrics vary depending on the application requirements. In order to ensure that the fabrics can meet the requirements of the expected use scenarios after leaving the factory, the fabrics need to be tested for durability before leaving the factory to improve product quality. However, the existing testing methods for textile fabrics have obvious limitations.

[0003] In the related art, the testing method for textile fabrics is to fix the two ends of the textile fabric and then pull them in opposite directions horizontally to test the tearing strength of the textile fabric. Although this single testing method can reflect the tensile performance of the fabric in its length direction, it ignores the more complex stress scenarios that the fabric may encounter in actual applications.

[0004] For example, when the textile fabric is in a twisted state in its own length direction, its strength characteristics have not been effectively evaluated; for another example, when the surface of the textile fabric is subjected to a twisting force, its performance has not been tested. More importantly, the detection of the surface torque of the textile fabric when the surface of the textile fabric is subjected to a twisting force is a key detection point that most manufacturers easily overlook. In many usage scenarios, the textile fabric will be in a state of surface tearing. Therefore, the detection method in the prior art cannot fully reflect the performance characteristics of the fabric under multi-dimensional force conditions, resulting in a lack of representativeness in the test results, and it is difficult to accurately evaluate the durability of the fabric in actual use. The limitations of this detection method in the prior art may cause the performance of the fabric in certain application scenarios to fall short of expectations, thereby affecting its service life and reliability, and thus reducing the detection effect of the textile fabric.

DETAILED DESCRIPTION

[0018] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] The following is further described in conjunction with specific embodiments. Figure 1 to Figure 10The present invention is a device for testing the mechanical properties of textile fabrics, comprising a horizontal pulling mechanism 1, a linear twisting mechanism 2 and a surface twisting mechanism 3; wherein the horizontal pulling mechanism 1 is symmetrically provided with two groups along the horizontal straight line direction, so that the textile fabric to be tested can be stretched straight in its own length direction. Exemplarily, the horizontal pulling mechanism 1 includes a pressure sensor 11, a rodless cylinder 12 and a first frame 13. The first frame 13 is arranged on the movable piston of the rodless cylinder 12. The pressure sensor 11 is arranged on the movable piston of the rodless cylinder 12 and is used to contact the first frame 13. The length directions of the two groups of rodless cylinders 12 are on the same horizontal straight line. The textile fabric can be connected to the top of the first frame 13. When the textile fabric is horizontally connected between the two first frames 13, when the movable pistons of the two relative rodless cylinders 12 move in opposite directions, the first frame 13 contacts the pressure sensor 11, so that when detecting the horizontal pulling strength of the textile fabric, the ultimate pulling strength of the textile fabric can be understood through the pressure sensor 11.

[0021] Exemplarily, the linear screwing mechanism 2 is arranged on the first frame 13, and the linear screwing mechanism 2 includes a first torque sensor 21, a rotating assembly 22 and a clamping assembly 23. The rotating assembly 22 is installed on the top of the first frame 13, and the clamping assembly 23 is installed on the rotating assembly 22 and is used to clamp the end of the textile fabric. The rotating assembly 22 can drive the clamping assembly 23 that clamps the textile fabric to rotate, so that the textile fabric is twisted from the extended state to the spiral state under the action of the rotating assembly 22. The first torque sensor 21 is electrically connected to the rotating assembly 22 and is used to detect the torque output by the rotating assembly 22 at the moment. Through the linear screwing mechanism 2, the detected textile fabric can be rotated from both ends to the middle, so that the textile fabric is twisted from the extended state to a spiral state similar to a "twist" shape, and the first torque sensor 21 can always sense the torque applied to the textile fabric by the rotating assembly 22, so as to facilitate the detection of the limit torque of the textile fabric, and finally determine whether the torque strength of the textile fabric meets the preset requirements.

[0022] Exemplarily, the surface twisting mechanism 3 includes a second frame 31, a second torque sensor 32, an active twisting assembly 33 and a driven twisting assembly 34. The second frame 31 is installed between the two sets of horizontal pulling mechanisms 1. The active twisting assembly 33 is vertically moved above the textile fabric in a horizontally stretched state on the second frame 31. The driven twisting assembly 34 is installed on the second frame 31 and below the textile fabric in a horizontally stretched state. The active twisting assembly 33 can rotate on the second frame 31. After the active twisting assembly 33 moves vertically downward, it cooperates with the driven twisting assembly 34. Four groups of clamping fixed points are formed to clamp the textile fabric, wherein the four groups of clamping fixed points cooperate with each other in pairs. Under the self-rotation of the active torsion component 33, the clamping fixed points opposite to each other in pairs approach each other and squeeze the textile fabric part to form a protrusion to form an extrusion force point. Under the continued self-rotation of the active torsion component 33, the surface of the textile fabric is twisted from the extended state to the pulled state. The second torque sensor 32 is installed on the frame and electrically connected to the active torsion component 33, and is used to measure the torque of the active torsion component 33 when the active torsion component 33 drives the textile fabric to twist. It is worth noting that the surface torque of the textile fabric is a key detection point that most manufacturers easily overlook, and the textile fabric will be in a state of surface tearing in many usage scenarios. Therefore, when detecting the surface torque strength of the textile fabric, the active torsion component 33 is actively brought close to the driven torsion component 34, and after clamping part of the surface of the textile fabric between the two, the active torsion component 33 is rotated so that the clamping fixed points relative to each other are close to each other and the textile fabric part is squeezed to form a protrusion. In this way, under the continued rotation of the active torsion component 33, the active torsion component 33 can clamp this part of the protrusion and drive part of the textile fabric to twist on its surface, and the second torque sensor 32 can always sense the torque applied by the active torsion component 33 to the surface of the textile fabric, so as to facilitate the detection of the limit torque of the surface of the textile fabric, and finally determine whether the torque strength of the surface of the textile fabric meets the preset requirements.

[0023] In summary, through a detection device of the present application, the horizontal tensile strength of the textile fabric, the torque strength along the straight line of the textile fabric, and the torque strength on the surface of the textile fabric can be detected to improve the strength detection range of the textile fabric, so that after the detection of the detection device, the detection results of the detected textile fabric are more representative, thereby ultimately improving the detection effect of the textile fabric.

[0024] In some embodiments, in combination Figure 1~Figure 3, a mounting plate 121 is provided on the moving piston of the rodless cylinder 12, a mounting groove 1211 is provided in the mounting plate 121, a first frame 13 is embedded in the mounting groove 1211, and a pressure sensor 11 is installed on the inner wall of the mounting groove 1211. When the moving pistons of the two groups of relative rodless cylinders 12 move in opposite directions, the part of the first frame 13 located in the mounting groove 1211 is horizontally in contact with the pressure sensor 11. After such arrangement, after starting the two rodless cylinders 12 so that the moving pistons of the two rodless cylinders 12 move in opposite horizontal directions, the force of the textile fabric being pulled will act between the frame and the pressure sensor 11, so that the pressure sensed by the pressure sensor 11 is the pulling force on the textile fabric, so that the horizontal pulling force on the textile fabric in the current pulling environment can be quickly detected, so as to more conveniently detect the ultimate pulling strength of the textile fabric.

[0025] In some embodiments, in combination Figure 1~Figure 3 The rotating assembly 22 includes a first torque motor 221 and a mounting seat 222. The mounting seat 222 is arranged on the output shaft of the first torque motor 221. The first torque sensor 21 is electrically connected to the side of the first torque motor 221 away from the mounting seat 222. The clamping assembly 23 is mounted on the mounting seat 222. After the clamping assembly 23 clamps the end of the textile fabric, the first torque motor 221 is started, and the mounting seat 222 drives the clamping assembly 23 to rotate. At this time, the two corresponding first torque motors 221 are rotated in opposite directions, so that the textile fabric can be spirally wound under the action of the two clamping assemblies 23, that is, it can be folded in its own circumferential direction to form a "twisted" spiral state, and the first torque sensor 21 is electrically connected to the first torque motor 221, so that the first torque motor can sense the force of the first torque motor 221 at any time, so that the torque of the textile fabric in the current torsional environment can be quickly detected, so as to more conveniently detect the pulling strength of the textile fabric in the circumferential direction.

[0026] In some embodiments, in combination Figure 1~Figure 3 The clamping assembly 23 includes a first cylinder 231, an upper pressing plate 232 and a lower pressing plate 233. The first cylinder 231 is mounted on the mounting seat 222, and the piston rod of the first cylinder 231 extends vertically downward. The upper pressing plate 232 is mounted on the end of the piston rod of the first cylinder 231. The lower pressing plate 233 is mounted on the mounting seat 222 and is located directly below the upper pressing plate 232. An embedding gap for the textile fabric to be embedded is formed between the upper pressing plate 232 and the lower pressing plate 233. When the first cylinder 231 is started, the piston rod of the first cylinder 231 is extended, thereby driving the upper pressing plate 232 to approach the lower pressing plate 233, so that the textile fabric can be stably clamped in the embedding gap.

[0027] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6 The active torsion assembly 33 includes a second cylinder 331, a telescopic frame 332, a second torque motor 333, a rotary motor 334, a rotating column 335, a U-shaped frame 336, a first clamping plate 337 and a second clamping plate 338. Exemplarily, the second cylinder 331 is arranged at the top of the second frame 31 and the piston rod of the second cylinder 331 extends vertically downward, the telescopic frame 332 is telescopically mounted on the second frame 31, and the second cylinder 331 is used to push the telescopic frame 332 to rise and fall in the vertical direction. Exemplarily, the telescopic frame 332 includes a plate body, a telescopic tube and a telescopic column, the telescopic column is vertically arranged at the top of the second frame 31, the telescopic tube is arranged on the outer peripheral wall of the plate body, and the telescopic column and the telescopic tube are slidably plugged in cooperation.

[0028] Exemplarily, the second torque motor 333 is mounted on the plate body of the telescopic frame 332, and the output shaft of the second torque motor 333 extends vertically downward, the rotating motor 334 is coaxially mounted on the output shaft of the second torque motor 333, and the output shaft of the rotating motor 334 also extends vertically downward; Exemplarily, the rotating column 335 is coaxially mounted on the output shaft of the rotating motor 334, the U-shaped frame 336 is fixedly arranged on the motor housing of the rotating motor 334 and is located at the periphery of the rotating column 335, and the first clamping plate 337 is vertically and spaced apart on the periphery of the rotating column 335 Two, second clamping plates 338 are vertically arranged at opposite ends of the U-shaped frame 336, one first clamping plate 337 corresponds to one second clamping plate 338 in the horizontal circumferential direction, and a clamping gap for clamping textile fabrics is formed between the first clamping plate 337 and the second clamping plate 338; illustratively, when the rotating motor 334 rotates, the first clamping plate 337 can gradually approach or move away from the corresponding second clamping plate 338 so that the clamping gap gradually decreases or increases, and the rotation direction of the rotating motor 334 is opposite to the rotation direction of the second torque motor 333.

[0029] In this way, the second cylinder 331 is started, so that the piston rod of the second cylinder 331 extends vertically downward, and the telescopic frame 332 moves downward synchronously at this time, driving the first clamping plate 337 and the second clamping plate 338 to approach the upper surface of the textile fabric until they are in contact with each other. Then, the rotating motor 334 is started, and the rotating motor 334 drives the rotating column 335 to rotate, so that the first clamping plate 337 approaches the second clamping plate 338. Since the first clamping plate 337 is in contact with the upper surface of the textile fabric, under the rotation action of the first clamping plate 337, the textile fabric can be pushed by the first clamping plate 337 to produce a bulge, so that after the first clamping plate 337 approaches and is in contact with the second clamping plate 338, part of the bulge of the textile fabric can be clamped between the first clamping plate 337 and the second clamping plate 338. At this time, the second torque motor 333 is started again, so that the first clamping plate 337 and the second clamping plate 338 in the clamped state can drive the bulge of the textile fabric to act on the surface of the textile fabric to twist, so that the torque on the surface of the textile fabric can be detected. At the same time, the second torque sensor 32 is installed on the housing of the second torque motor 333 and is electrically connected to the second torque motor 333. The second torque sensor 32 can conveniently detect the limit torque on the surface of the textile fabric, and ultimately determine whether the torque strength on the surface of the textile fabric meets the preset requirements.

[0030] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6 The driven torsion assembly 34 includes a positioning frame 341, a positioning column 342, an L-shaped rod 343, a receiving plate 344, an iron ball 345 and a supporting telescopic rod 346; illustratively, the positioning frame 341 is installed on the second frame 31, the positioning column 342 is installed above the positioning frame 341 and is axially opposite to the rotating column 335, two groups of arc-shaped grooves 3420 are symmetrically opened on the outer wall of the positioning column 342, the iron ball 345 is arranged at the end of the L-shaped rod 343, and the iron ball 345 is rollingly embedded in the arc-shaped groove 3420, the receiving plate 344 is horizontally arranged on the top of the L-shaped rod 343, and the number of the receiving plates 344 is four, of which two receiving plates 344 correspond to the two first clamping plates 337 respectively, and the other two receiving plates 344 correspond to the two second clamping plates 338 respectively.

When the second cylinder 331 drives the rotating column 335 to move vertically downward, the arc-shaped protrusion 339 of the first clamping plate 337 and the arc-shaped protrusion 339 of the second clamping plate 338 can be adaptively embedded in the arc-shaped recessed portion 3440 to clamp the textile fabric between the arc-shaped protrusion 339 and the arc-shaped recessed portion 3440, thereby forming a clamping fixed point acting on the textile fabric.

[0032] Exemplarily, the arc-shaped slide groove 3420 includes a horizontal section 3421 and a concave section 3422, and the horizontal section 3421 is respectively connected to each other at both ends of the concave section 3422. A magnet block 3423 is provided on the inner wall of one end of the horizontal section 3421 away from the concave section 3422. The magnet block 3423 is used to magnetically attract the iron ball 345, and when the magnet block 3423 is magnetically fitted with the iron ball 345, each receiving plate 344 is vertically opposite to a first clamping plate 337 or a second clamping plate 338. Exemplarily, a fixed cylinder 347 is rotatably provided on the outer periphery of the positioning column 342 and located below the arc-shaped slide groove 3420. The top end of the support telescopic rod 346 is connected to the L-shaped rod 343, and the bottom end is connected to the upper end wall of the fixed cylinder 347. The support telescopic rod 346 can adaptively extend and retract as the L-shaped rod 343 moves, so that the iron ball 345 can roll stably in the arc-shaped slide groove 3420.

[0033] Exemplarily, when the textile fabric is clamped between the arc-shaped protrusion 339 and the arc-shaped recessed portion 3440 to form a clamping fixed point, the iron ball 345 moves in the horizontal section 3421 and drives the first clamping plate 337 to gradually rotate circumferentially close to the second clamping plate 338. The two clamping fixed points gradually approach each other, so that part of the textile fabric between the two clamping fixed points forms a protrusion under the action of squeezing, until the first clamping plate 337 abuts against the second clamping plate 338, and the protruding part of the textile fabric is stably clamped between the first clamping plate 337 and the second clamping plate 338.

[0034] At the same time, when the textile fabric is clamped between the arc-shaped protrusion 339 and the arc-shaped recessed portion 3440 to form a clamping fixed point, during the process of the iron ball 345 moving from the horizontal section 3421 to the recessed section 3422, the receiving plate 344 gradually moves downward away from the corresponding first clamping plate 337, so that part of the textile fabric has formed a protrusion under the extrusion effect, and the arc-shaped recessed portion 3440 moves away from the arc-shaped protrusion 339 on the corresponding first clamping plate 337, until the first clamping plate 337 drives the protruding part of the textile fabric to abut against the second clamping plate 338; similarly, when the second clamping plate 338 is started, When the second torque motor 333 is turned on and the rotating motor 334 is turned off, the second torque motor 333 drives the first clamping plate 337 and the second clamping plate 338 in the abutment state to rotate in opposite directions. At this time, the receiving plate 344 corresponding to the second clamping plate 338 is synchronously pushed to move in the arc-shaped slide groove 3420 until the corresponding iron ball 345 moves from the horizontal section 3421 to the concave section 3422. The corresponding receiving plate 344 also gradually moves downward away from the second clamping plate 338, so that the receiving plate 344 does not affect the surface torque detection of the textile fabric after the second torque motor 333 is started.

[0035] On this basis, combined with Figure 7~Figure 10, because after the first clamping plate 337 is attached to the upper surface of the textile fabric, it is very likely that the textile fabric cannot be normally driven to form a bulge when the first clamping plate 337 moves circumferentially. In this case, after the first clamping plate 337 moves downward, the arc-shaped protrusion 339 of the first clamping plate 337 will adaptively cooperate with the arc-shaped recessed portion 3440 of the receiving plate 344, thereby clamping part of the textile fabric between the arc-shaped protrusion 339 and the arc-shaped recessed portion 3440, thereby forming a clamping fixed point acting on the textile fabric. At this time, after starting the rotating motor 334, the circumferential rotation of the first clamping plate 337 will synchronously drive the corresponding receiving plate 344 to move together in the horizontal section 3421 of the arc-shaped slide groove 3420, and under the action of the formed clamping fixed point, the textile fabric will form a bulge upward. It is worth noting that since the arc-shaped protrusion 339 of the first clamping plate 337 protrudes downward, and the arc-shaped recessed portion 3440 of the receiving plate 344 is recessed upward, the portion of the textile fabric clamped between the arc-shaped protrusion 339 and the arc-shaped recessed portion 3440 and close to the clamping gap side must be tilted upward. Under the guidance of this upward-tilted textile fabric, after the first clamping plate 337 approaches the second clamping plate 338, the textile fabric between the first clamping plate 337 and the second clamping plate 338 must be protruding (bulging) upward, so that the first clamping plate 337 and the second clamping plate 338 can successfully clamp the protrusion (bulge) of the textile fabric after being fitted.

[0036] At the same time, when the iron ball 345 moves from the horizontal section 3421 to the concave section 3422, the receiving plate 344 will gradually move away from the first clamping plate from the position close to the first clamping plate, because the protrusion (ridge) of the textile fabric between the first clamping plate 337 and the second clamping plate 338 has been formed during the movement of the receiving plate 344 in the horizontal section 3421, and at this time, the receiving plate 344 is not required to form a clamping fixed point with the first clamping plate 337. At this time, the receiving plate 344 can be moved downward away from the first clamping plate 337, so that the receiving plate 344 corresponding to the first clamping plate 337 will not affect the subsequent detection of the surface torque of the textile fabric. Similarly, when the first clamping plate 337 and the second clamping plate 338 clamp the protruding (raised) textile fabric, when the second torque motor 333 drives the first clamping plate 337 and the second clamping plate 338 in the clamping state to rotate in the opposite direction, the receiving plate 344 corresponding to the second clamping plate 338 will gradually separate from the second clamping plate 338 during the movement, that is, when it is necessary to detect the surface torque of the textile fabric, the receiving plates 344 corresponding to the first clamping plate 337 and the second clamping plate 338 will gradually move to a position that will not interfere with the textile fabric, that is, at this time, the iron balls 345 corresponding to the receiving plates 344 will roll into the concave section 3422.

[0037] Exemplarily, the supporting telescopic rod 346 includes a sleeve and a sleeve rod. The sleeve is hollow inside and has an opening at the upper end. The sleeve is vertically arranged on the top wall of the fixed cylinder 347, and the sleeve rod is vertically arranged below the transverse rod section of the L-shaped rod 343. The sleeve rod is vertically slidably inserted into the sleeve, so that when the iron ball 345 slides in the arc-shaped slide groove 3420, the sleeve rod can be adaptively extended or retracted in the sleeve.

[0038] In some embodiments, in combination Figure 4 and Figure 5 The first clamping plate 337 and the second clamping plate 338 are provided with continuous depressions and protrusions on the surfaces close to each other, and the protrusions on the first clamping plate 337 and the depressions on the second clamping plate 338 are adaptively matched when the two are circumferentially rotated and fitted. By setting the depressions and protrusions, the textile fabric can be clamped more stably between the first clamping plate 337 and the second clamping plate 338, and is not easy to slip when the surface torque of the textile fabric is tested.

[0039] In some embodiments, in combination Figure 5 , the first clamping plate 337 and the U-shaped frame 336 are also provided with an adsorption component 4, which is used to generate an adsorption force acting on the protrusion after a part of the textile fabric has formed a protrusion under the extrusion and the receiving plate 344 gradually moves downward away from the corresponding first clamping plate 337, so as to prevent the protrusion from collapsing after forming. Exemplarily, the adsorption component 4 includes a connecting frame 41, a suction fan 42, a hose 43 and an adsorption tube 44, the adsorption tube 44 is embedded in the first clamping plate 337, the adsorption end of the adsorption tube 44 is located in the depression of the first clamping plate 337 and faces the protrusion surface formed by the part of the textile fabric under the extrusion, one end of the hose 43 is connected to the adsorption tube 44, and the other end is connected to the suction port of the suction fan 42, the connecting frame 41 is arranged on the U-shaped frame 336, and the suction fan 42 is installed on the connecting frame 41.

[0040] After such arrangement, after part of the textile fabric has formed a protrusion under the extrusion and the receiving plate 344 gradually moves downward away from the corresponding first clamping plate 337, due to the lack of the restriction of the clamping fixed point, the protruding (protruding) part of the textile fabric may also collapse and then leave between the first clamping plate 337 and the second clamping plate 338. Therefore, in order to prevent the above situation from happening, when the receiving plate 344 corresponding to the first clamping plate 337 gradually leaves the first clamping plate 337, the suction fan 42 is started to generate suction, so that the suction tube 44 generates suction acting on the surface of the protruding (protruding) part of the textile fabric, so that the surface of the protruding (protruding) part of the textile fabric is not easy to collapse after being subjected to the suction generated by the suction tube 44, thereby improving the shape stability of the protruding (protruding) part of the textile fabric after the receiving plate 344 leaves the first clamping plate 337. It is worth noting that after the receiving plate 344 is away from the first clamping plate 337, the position of the first clamping plate 337 is very close to the second clamping plate 338. Therefore, the adsorption force generated by the adsorption is only a temporary supporting suction force, and is not the most important external forming force for the protruding (protruding) part of the textile fabric. After the first clamping plate 337 and the second clamping plate 338 are attached, the protruding (protruding) part of the textile fabric can be clamped. Please refer to the movement process. Figure 7~Figure 10 .
