Description

Technical Field

[0001] The invention relates to the technical field of tensile performance detection, in particular to a yarn tensile performance detection device for knitted sweater production. Background Art

[0002] Yarn is a kind of textile, which is processed into products of a certain fineness from various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc.

[0003] There are many ways to express the fineness of yarn, such as number, metric count, imperial count, denier, etc. (see count). The twist of yarn is expressed in the number of turns per meter or per inch.

[0004] Wool yarn and wool thread are generally used to weave wool sweaters, wool trousers, wool vests, scarves, hats and gloves, and to weave various spring and autumn clothing items. In addition to keeping warm, they also have decorative functions.

[0005] The existing tensile performance testing device usually clamps the yarn with a three-jaw chuck or a clamping structure. The three-jaw chuck needs to be wound many times, which is very troublesome to use. In addition, the yarn often falls off during the actual stretching process, which affects the accuracy of the test. When the clamping structure clamps the yarn, the clamping force applied by the clamping structure to the yarn is easy to cause the yarn and the clamping structure to break, resulting in inaccurate detection.

[0006] On the other hand, when limiting the length of the yarn, it is troublesome to adjust the stretching height data, which affects the subsequent test results. Summary of the invention

[0017] As a preferred technical solution of the present invention: the inner wall of the docking groove conflicts with the outer wall of the pressure sensor 1, and the end of the return spring away from the rotating plate is connected to the outer wall of the connecting block.

[0018] The present invention has the following beneficial effects:

[0019] 1. The yarn tensile property testing device for knitted sweater production, through the provided main body, horizontal plate, circular plate, wire release groove, wire clamping groove one, wire clamping groove two and gear structure, enables the user to directly place the thread end in the wire clamping groove one during use of the testing device, and use a screwdriver to rotate the insertion rod so that the inner walls of the wire clamping groove one and the wire clamping groove two are tightly fitted with the outer wall of the thread end, thereby realizing fast fixing of the thread end, so that it is convenient for the user to wind the thread body between the two circular plates, and use the wire release groove to store the wound thread body, which is convenient for the user to install the thread body and also convenient for the user to adjust the length of the thread body. At the same time, before testing, the user can also rotate the circular plate counterclockwise by rotating the gear to automatically adjust the length of the thread body, which is convenient for the user to operate, thereby improving the user's detection efficiency of the thread body and the automation of the device.

[0020] 2. The yarn tensile performance testing device for knitted sweater production has a telescopic end, gears, gear rings, tooth grooves, reset springs, pressure sensors, and a rotating plate structure. When the device is in operation, the rotating plate is used to limit the circular plate, so that the circular plate cannot release the wire body when the wire body is pulled, ensuring that the wire body is always in a taut state after the rotating part tightens the wire body. The contact between the pressure sensor and the wire body is used to detect the tension on the wire body. The rotating part fixes the thread end and the wire body can be wound around the rotating part to avoid interference with the strength of the wire body caused by the clamping force, thereby improving the detection accuracy of the device for the wire body.

[0021] 3. In the yarn tensile performance testing device for knitted sweater production, the wire body is wound around the outer wall of the rotating part so that the wire bodies rub against each other, thereby fixing the wire body and the rotating part through the friction between the wire bodies. This solves the problem in traditional equipment that, during the process of clamping the yarn, the clamping force applied by the clamping structure to the yarn is prone to cause breakage at the clamping point of the yarn and the clamping structure, thereby causing inaccurate detection.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 10 A yarn tensile performance testing device for knitted sweater production includes a main body 1, a horizontal plate 2 is fixedly mounted on the top of the main body 1, a micro hydraulic rod assembly 3 is arranged on the top of the horizontal plate 2, a clamping plate 4 is fixedly mounted on the top of the horizontal plate 2, and a detection assembly 5 is arranged on the top of the clamping plate 4.

[0040] During the operation of the device, the user can directly place the thread end on the inner wall of the first clamping groove 5075, and the thread end will fit with the inner wall of the movable groove 5123, and then rotate the plug rod 5121 to make the second clamping groove 5124 turn to the inner wall of the first clamping groove 5075 close to the axis of the circular plate 5071, so that the thread end is initially fixed by the second clamping groove 5124 and the first clamping groove 5075, ensuring that the thread end cannot be loosened, and it is convenient for the user to wrap the wire body between the two circular plates 5071, so as to achieve the effect of quickly fixing the thread end, and then it is convenient for the user to adjust the length of the wire body, thereby improving the user's operating efficiency.

[0041] In a preferred embodiment, the micro hydraulic rod assembly 3 includes a fixing plate 301 , the inner wall of the fixing plate 301 is fixedly equipped with a cylinder body 302 , the inner cavity of the cylinder body 302 is provided with a telescopic end 303 , and the end of the telescopic end 303 is fixedly equipped with a connecting rod 304 .

[0042] In the above structure, through the structure of the telescopic end 303 and the connecting rod 304, the detection component 5 can be pulled to move by utilizing the telescopic effect of the telescopic end 303 and the connecting effect of the connecting rod 304. When the rotating member 507 cannot rotate clockwise, the user can directly rotate the gear 509 to make the rotating member 507 rotate counterclockwise, so that the rotating member 507 can reel in the wire to tighten the wire. There is no need for the user to manually adjust the length of the wire for a second time, which simplifies the operation process of the device and further improves the automation and detection accuracy of the device.

[0043] In a preferred embodiment, the detection assembly 5 includes a detection platform 501, a connection plate 502 is fixedly mounted on one end of the detection platform 501 close to the micro hydraulic rod assembly 3, a connection block 503 is fixedly mounted on the top of the detection platform 501, a rotating plate 504 is rotatably connected to the top of the detection platform 501, a return spring 505 is arranged on the outer wall of the rotating plate 504, a positioning rod 506 is fixedly mounted on the top of the detection platform 501, a rotating member 507 is rotatably connected to the outer wall of the positioning rod 506, and the top of the rotating member 507 is fixedly mounted on the top of the detection platform 501. A straight rod 508 is fixedly assembled on the top of the rotating member 507, a gear ring 514 is fixedly assembled on the bottom of the rotating member 507, a gear 509 is meshed on the outer wall of the gear ring 514, a rotating rod 510 is rotatably connected to the top of the testing platform 501, a positioning plate 511 is fixedly assembled on the end of the testing platform 501 away from the connecting plate 502, a yarn fixing component 512 is provided on the top inner wall of the rotating member 507, a pressure sensor 513 is provided at the end of the rotating plate 504, and a motor connected to the gear 509 is embedded in the inner cavity of the testing platform 501.

[0044] In the above structure, by setting the yarn fixing component 512, the rotating rod 510 and the pressure sensor 513 structure, during the detection process of the device, the contraction of the telescopic end 303 will cause the detection platform 501 to move, and the wire body will be fixed after the user rotates the insertion rod 5121, so that it is convenient for the user to wind the wire body, and the thread head is fully limited. Therefore, when the wire body generates a pulling force on the rotating member 507, the rotating member 507 is blocked by the rotating plate 504 and the pressure sensor 513, so that the wire body cannot pull the rotating member 507 to rotate, so that the pressure sensor 513 detects the pressure of the wire body pulling the rotating member 507, and because the wire body is wound around the outer wall of the rotating member 507, the wire bodies rub against each other, so that the wire body and the rotating member 507 are fixed by the friction between the wire bodies.

[0045] After the wire body and the two detection components 5 are fixed, the pressure between the wire body and the second pressure sensor 5102 is used to make the second pressure sensor 5102 detect the current tension of the wire body, so that when the device tests different wire bodies, it can observe whether the measurement environment of different wire bodies is consistent through the second pressure sensor 5102;

[0046] The synchronous sensing function of pressure sensor 5102 increases the source of pressure detection data, making it easier for users to compare pressure data detection results, thereby achieving the effect of quickly fixing the wire body and reducing the influence of clamping force on the wire body detection results, as well as dual-position detection of the wire body's tensile strength.

[0047] In a preferred embodiment, the rotating member 507 includes a circular plate 5071, a wire releasing groove 5072 and a wire clamping groove 5075 are respectively provided on the top of the circular plate 5071, a tooth groove 5073 is provided on the outer wall of the circular plate 5071, and a docking groove 5074 is provided on the inner wall of the tooth groove 5073.

[0048] In the above structure, through the structure of the wire release groove 5072 and the docking groove 5074, the detection device can use the wire release groove 5072 to accommodate the wire during use, so that the user can fix the wire end and directly wrap the wire between the two circular plates 5071, thereby facilitating the user to preliminarily adjust the length of the wire. The docking groove 5074 can hinder the rotating member 507 by abutting against the pressure sensor 513 after the rotating member 507 is pulled, thereby preventing the rotating member 507 from rotating clockwise to release the wire, thereby ensuring that the wire is always in a taut state during the detection process, thereby improving the detection accuracy of the device for the wire.

[0049] In a preferred embodiment: the rotating rod 510 includes a tensioning rod 5101, the outer wall of the tensioning rod 5101 is provided with a second pressure sensor 5102, the yarn fixing component 512 includes an insertion rod 5121, the top of the insertion rod 5121 is provided with a groove 5122, and the outer wall of the insertion rod 5121 is respectively provided with a second wire clamping groove 5124 and a movable groove 5123.

[0050] In the above structure, through the movable groove 5123, the second wire holding groove 5124 and the pressure sensor 2 5102 structure, the user can directly place the wire end between the movable groove 5123 and the first wire holding groove 5075, and then rotate the insertion rod 5121 to make the inner walls of the second wire holding groove 5124 and the first wire holding groove 5075 fit tightly with the outer wall of the wire end, ensuring that the user can directly fix the wire end by rotating the insertion rod 5121, thereby achieving the effect of quickly fixing the wire end and adjusting the length of the wire body. After the length of the wire body is adjusted and the telescopic end 303 is contracted, the wire body will be close to the outer wall of the second pressure sensor 5102, so that the wire body compresses the second pressure sensor 5102, thereby achieving the effect of detecting the tensile strength of the wire body.

[0051] In a preferred embodiment: a card slot is formed on the outer wall of the card plate 4 , and the inner wall of the card slot is slidably engaged with the outer wall of the connecting plate 502 .

[0052] In the above structure, by setting the card slot and the connecting plate 502 structure, the connection between the connecting rod 304 and the connecting plate 502 can ensure that the connecting plate 502 pulls the detection platform 501 to move when the telescopic end 303 is retracted, so that both ends of the line body are fixed by the rotating member 507 to test the tensile strength of the line body, and the card slot can facilitate the user to install the connecting plate 502, so that the connecting plate 502 can move toward the direction of the micro hydraulic rod assembly 3 when the telescopic end 303 is retracted, thereby avoiding the shaking of the detection assembly 5 and the separation from the card plate 4, thereby ensuring the normal operation of the device.

[0053] In a preferred embodiment, there are two circular plates 5071 , and the two circular plates 5071 are fixedly connected via a straight rod 508 .

[0054] In the above structure, the circular plate 5071 structure is used to accommodate the wire body, so that the user can directly wrap the wire body between the two circular plates 5071, thereby facilitating the user to connect the two ends of the wire body to the two detection components 5, thereby improving the user's installation and detection efficiency of the wire body.

[0055] In a preferred embodiment: the outer wall of the rotating member 507 is wrapped with a wire body, and the outer wall of the wire body is tightly fitted with the outer wall of the pressure sensor 2 5102, the outer wall of the positioning plate 511 is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected with the outer wall of the wire body.

[0056] In the above structure, by setting the limit groove structure, the two ends of the force point of the wire body are always on the same horizontal line when the wire body is pulled, avoiding the wire body from tilting, and further ensuring the detection effect of the device on the wire body.

[0057] In a preferred embodiment, the inner wall of the docking groove 5074 contacts the outer wall of the pressure sensor 513 , and the end of the return spring 505 away from the rotating plate 504 is connected to the outer wall of the connecting block 503 .

[0058] In the above structure, the reset spring 505 structure is set so that when the circular plate 5071 rotates counterclockwise, the rotating plate 504 and the detection table 501 rotate, so that the limiting effect of the rotating plate 504 on the rotating member 507 disappears, and the effect of tensioning the wire body is achieved. Conversely, the elasticity provided by the reset spring 505 allows the rotating plate 504 to be pulled by the rotating member 507 and have the kinetic energy to rotate clockwise, so that the outer wall of the pressure sensor 513 is always in close contact with the inner wall of the docking groove 5074, so that the rotating member 507 cannot release the wire body, thereby ensuring that the wire body is in a taut state, and the tension exerted on the wire body can also be detected.

[0059] Working principle: put the wire end in the first wire clamping groove 5075, then insert the screwdriver bit into the groove 5122, and rotate the screwdriver to rotate the plug rod 5121. At this time, the inner walls of the second wire clamping groove 5124 and the first wire clamping groove 5075 are both close to the outer wall of the wire end, so as to achieve the effect of quickly fixing the wire end. Then, the wire body is wound between the two circular plates 5071 to achieve the effect of quickly adjusting the length of the wire body. When the user fixes both ends of the wire body through the same steps above, the outer wall of the wire body will contact the second pressure sensor 5102. The outer wall of the test bench 501 is tightly fitted, and the user can drive the gear 509 to work through the motor embedded in the test bench 501, and use the gear 509 to mesh with the gear ring 514, so that the rotating member 507 rotates counterclockwise, thereby automatically tightening the wire body, without the need for manual adjustment by the user, thereby simplifying the operation process of the device, improving the automation of the device, and also avoiding the loosening of the wire body and affecting the test results. By observing the pressure value of the pressure sensor 2 5102 squeezed by the wire body, the wire body state meets the test requirements;

[0060] After the detection starts, the telescopic end 303 will pull the detection component 5 to move toward the micro hydraulic rod component 3. At this time, the wire body will further compress the pressure sensor 2 5102, and at the same time, the wire body will generate tension on the circular plate 5071, but the rotating part 507 is limited by the obstruction of the rotating plate 504 and cannot rotate clockwise to release the wire body, thereby ensuring that the wire body is in a taut state to detect the tensile strength of the wire body. The pulling force of the wire body on the rotating part 507 will make the outer wall of the pressure sensor 1 513 fit tightly with the inner wall of the docking groove 5074, thereby achieving the effect of the pressure sensor 1 513 and the pressure sensor 2 5102 synchronously detecting the tension on the wire body. The user can take the average value of the detection data of the two after the wire body is broken, thereby improving the detection accuracy of the device for the wire body.
