Description

TECHNICAL FIELD

[0002] In a textile industrial production chain, yarn as a core raw material is applied to multiple scenes from daily clothing to industrial fields, including clothing, household textiles and industrial textiles, etc., and a detection device needs to be used to detect the tension of the yarn in the yarn production process.

[0003] A patent application with the publication number CN109186834B discloses a yarn tension detection device for textiles, which comprises a placing mechanism, and a detection mechanism is arranged on one side of the placing mechanism. The placing mechanism is composed of a bottom plate, a supporting column, a fixed display plate, a fixed clamp and a label. The supporting column is installed on the bottom plate. The detection mechanism comprises a clamping air cylinder, a pressure sensor and a measuring cylinder. The yarn to be detected is pulled to the detection structure and clamped by the clamping air cylinder. One of the clamping air cylinders is controlled to move to stretch the yarn until the yarn is broken. The stress and the stretching length of the yarn can be detected by the pressure sensor and the measuring cylinder.

[0004] To ensure the accuracy of the detection result, the same sample needs to be detected by multiple sampling. However, after the single detection is completed, the online preparation for the next detection needs to be completed by manual operation in the above scheme, which leads to low detection efficiency.

DETAILED DESCRIPTION

[0022] In order to make the technical means, purposes and effects achieved by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0023] As Figure 1 -Figure 10 As shown, the continuous yarn tension rapid detection device of the embodiment of the application comprises a machine body 1, a tension detection assembly 2 and a feeding assembly 3. The tension detection assembly 2 comprises two clamping structures 21, one of which is slidingly assembled on the machine body 1, and a force sensor 22 and a cylinder 1 23 are arranged on the clamping structure 21. The force sensor 22 is located between the cylinder 1 23 and the clamping structure 21, and is used to collect the tension data of the yarn. The cylinder 1 23 provides a power source for the sliding of the clamping structure 21. The feeding assembly 3 comprises a mounting plate 31 rotatingly mounted on the machine body 1, a circular plate 32 rotatingly mounted on the mounting plate 31, a first annular plate 33 mounted on the circular plate 32, a guide rod 1 34 fixedly mounted on the first annular plate 33, a first clamping plate 35 fixedly mounted on the end of the guide rod 1 34 away from the first annular plate 33, and a second clamping plate 36 slidingly assembled on the guide rod 1 34. The first clamping plate 35 and the second clamping plate 36 are used to clamp the end of the yarn and move from one side of one clamping structure 21 to the other side of the other clamping structure 21 under the rotation of the mounting plate 31, so as to realize the feeding of the yarn.

[0024] Specifically, in order to ensure the accuracy of the detection result, the same sample needs to be detected by multiple sampling. However, after the single detection of the prior art is completed, the online preparation for the next detection needs to be completed by manual operation, which leads to low detection efficiency. Especially for longer yarns, sufficient spacing between samples needs to be ensured during sampling to further improve the accuracy of the results. The efficiency problem is more prominent under this operation mode. A guide wheel is mounted on the machine body 1. The plate on which the guide wheel is mounted is slidingly connected with the machine body 1, so that the yarn is always in a tension state during the feeding process. The rotation of the mounting plate 31 is controlled in an electric manner. Before work, the yarn reel is mounted on the machine body 1 (the yarn reel can rotate synchronously during feeding, and the mechanism is the prior art), the end of the yarn is passed through the guide wheel and placed between the first clamping plate 35 and the second clamping plate 36, the second clamping plate 36 is controlled to move relative to the first clamping plate 35 to realize the action of clamping the end of the yarn. At this time, the end of the yarn is located on one side of one clamping structure 21. When working, the control installation plate 31 rotates, the installation plate 31 drives the circular plate 32, the first annular plate 33, the guide rod one 34 to rotate synchronously, the guide rod one 34 drives the first clamping plate 35 and the second clamping plate 36 to rotate synchronously, so that the end of the yarn moves, until the installation plate 31 rotates 180 degrees, at this time, the end of the yarn is located on the other side of the other clamping structure 21, the yarn is in a tension state between the two clamping structures 21, then the clamping structure 21 is controlled to clamp the yarn, the cylinder one 23 is controlled to start, the slidingly assembled clamping structure 21 slides along the machine body 1, so that the yarn between the two clamping structures 21 is stretched under stress until the yarn is broken, the action of the cylinder one 23 is stopped and reset, and the force sensor 22 continuously collects the tension data of the yarn in real time during the stretching and breaking of the yarn, and transmits the tension data to the system; Then the slidingly assembled clamping structure 21 is controlled to loosen the yarn, and the circular plate 32 is controlled to rotate to drive the first annular plate 33 to rotate, the first annular plate 33 drives the first clamping plate 35 and the second clamping plate 36 to rotate, so as to move the yarn remaining on the clamping structure 21 after breaking away, the circular plate 32 is controlled to rotate reversely to reset the first clamping plate 35 and the second clamping plate 36, then the second clamping plate 36 is controlled to move away from the first clamping plate 35 to loosen the broken yarn, the installation plate 31 is controlled to rotate reversely to reset, after resetting, the new yarn segment is located between the first clamping plate 35 and the second clamping plate 36 again, the second clamping plate 36 is controlled to move close to the first clamping plate 35 and clamp the yarn, and the other clamping structure 21 is controlled to reset (loosen the end of the yarn), so as to complete a single detection cycle, at this time, the device can repeat the above rotating and detecting steps to realize continuous feeding and continuous detection; During the rotation of the installation plate 31, the circular plate 32 can be controlled to rotate to drive the first clamping plate 35 and the second clamping plate 36 to rotate synchronously, so as to wind part of the yarn on the first clamping plate 35 and the second clamping plate 36, to ensure that there is enough space between the samples during sampling; Through the setting of the feeding assembly 3, automatic feeding, continuous detection and automatic cleaning of residues can be realized, the above problems are improved, the detection efficiency is improved, and the first clamping plate 35 and the second clamping plate 36 can rotate to wind the yarn, so as to accurately control the sample spacing of multiple sampling and effectively ensure the accuracy of the detection result.

[0025] As shown in Figure 1 , Figure 5 , Figure 6 and Figure 7 , the feeding assembly 3 further comprises: a guide rod two 37 fixedly installed on the circular plate 32, the first annular plate 33 is slidably connected with the circular plate 32 through the guide rod two 37; a second annular plate 38 fixedly installed on the installation plate 31, the first annular plate 33 is threadedly connected with the second annular plate 38.

[0026] Specifically, during the rotation of the mounting plate 31, when it is necessary to wind the yarn through the first clamping plate 35 and the second clamping plate 36 to ensure the sampling interval, the first annular plate 33 rotates synchronously. Since the first annular plate 33 is in threaded connection with the fixed second annular plate 38, the first annular plate 33 will move radially during the rotation due to the threaded engagement, thereby driving the first clamping plate 35 and the second clamping plate 36 to move synchronously. As a result, the yarn can be evenly distributed on the first clamping plate 35 and the second clamping plate 36 during the winding process, avoiding local accumulation, and ensuring that the wound yarn always remains parallel to the cylinder 23, thereby ensuring that the subsequent yarn can accurately pass between the two clamping structures 21, avoiding detection errors or feeding failures caused by yarn deviation.

[0027] As shown in Figure 1 , Figure 4 and Figure 5 , the feeding assembly 3 further comprises a gear one 39 fixedly installed on the circular plate 32; a gear two 310 rotatably installed on the mounting plate 31, the gear one 39 and the gear two 310 are in meshing connection; a cylinder two 311 fixedly installed on the first annular plate 33, the movable end of the cylinder two 311 is connected with the second clamping plate 36.

[0028] Specifically, the rotation of the gear two 310 adopts an electric driving mode, and the sliding of the second clamping plate 36 relative to the first clamping plate 35 is controlled by the cylinder two 311; by controlling the rotation of the gear two 310, the circular plate 32 can be driven to rotate synchronously by the gear one 39, and the rotation of the circular plate 32 causes the first clamping plate 35 and the second clamping plate 36 to rotate, thereby achieving the winding and unwinding actions.

[0029] As shown in Figure 1 and Figure 3 - Figure 6 , it further comprises a collecting assembly 4, which comprises a ring plate 41 rotatably installed on the first annular plate 33; a containing shell 42 installed on the ring plate 41, the containing shell 42 is in sliding connection with the ring plate 41, and a spring three is installed between the containing shell 42 and the ring plate 41; an inlet 43 opened on the containing shell 42; a suction structure 44 installed on the mounting plate 31, a pipeline 45 for communication is installed between the suction structure 44 and the containing shell 42; a filter plate 46 installed inside the containing shell 42, the filter plate 46 is used to block the yarn from entering the pipeline 45; an electromagnet 47 is arranged on the second annular plate 38, and a magnet is arranged on one end of the containing shell 42 close to the electromagnet 47. By electrifying the electromagnet 47, a magnetic field is generated to drive the containing shell 42 to move relative to the ring plate 41, thereby achieving the position adjustment of the containing shell 42.

[0030] As shown in Figure 3 - Figure 8As shown, the air suction structure 44 comprises: a cylinder 441 fixedly installed on the mounting plate 31; a disc 442 slidably installed in the cylinder 441; a screw rod 443 rotatably installed on the mounting plate 31, the screw rod 443 being threadedly connected with the disc 442; an air inlet hole and an air outlet hole being formed in the cylinder 441, the air inlet hole and the air outlet hole being respectively connected with a first baffle plate 444 and a second baffle plate 445, the first baffle plate 444 and the second baffle plate 445 being installed between the cylinder 441 and springs one and two, the air inlet hole being communicated with the pipeline 45; a gear three 446 fixedly installed on the screw rod 443; a one-way transmission gear set 447 for transmission, the one-way transmission gear set 447 being rotatably installed on the mounting plate 31, the gear two 310 rotating to drive the gear three 446 to rotate through the one-way transmission gear set 447.

[0031] Specifically, the screw rod 443 is a reciprocating screw rod 443, the first baffle plate 444 can only slide towards the inside of the cylinder 441 (only allowing gas to enter the cylinder 441 from the containing shell 42), the second baffle plate 445 can only slide towards the outside of the cylinder 441 (only allowing gas to be discharged from the cylinder 441 to the outside), the one-way transmission gear set 447 comprises two gears meshing with each other, one of the gears is coaxial with the gear two 310 and the two gears are one-way transmission, the other gear is meshed with the gear three 446, when the gear two 310 drives the first clamp plate 35 and the second clamp plate 36 to rotate and wind the yarn thereon, the one-way transmission gear set 447 remains stationary, and vice versa, the gear two 310 drives the gear three 446 to rotate through the one-way transmission gear; After the detection is completed, before the control gear two 310 is reversed to loosen the yarn, the electromagnet 47 on the second annular plate 38 is powered on first, the electromagnet 47 generates a magnetic field that interacts with the magnet on the containing shell 42, driving the containing shell 42 to slide relative to the ring plate 41 against the elastic force of the spring three, until the containing shell 42 completely sleeves the first clamp plate 35 and the second clamp plate 36 inside, and then the control gear two 310 is reversed to rotate, so that the yarn on the first clamp plate 35 and the second clamp plate 36 is loosened and falls onto the containing shell 42, while the gear two 310 drives the gear three 446 and the lead screw 443 to rotate, the lead screw 443 rotates to drive the disc 442 to reciprocate relative to the cylinder 441, when the disc 442 moves towards the installation plate 31, the internal volume of the cylinder 441 increases, the air pressure decreases, forming a negative pressure, the first baffle plate 444 slides to the inside of the cylinder 441 under the action of the internal and external air pressure difference, the spring one is stretched, at this time the cylinder 441 communicates with the containing shell 42 through the pipeline 45, the containing shell 42 generates suction at the feed inlet 43, and the broken yarn falling from the feed inlet 43 is sucked into the containing shell 42 for storage, when the disc 32 moves away from the installation plate 31, the first baffle plate 444 resets under the action of the spring one, the cylinder 441 and the containing shell 42 are not connected, the air pressure in the cylinder 441 increases, the second baffle plate 445 slides to the outside of the cylinder 441 under the action of the air pressure difference, the spring two is compressed, the cylinder 441 communicates with the outside through the air outlet, and the internal gas is discharged to balance the air pressure in the cylinder 441, so as to realize the cleaning work of the broken yarn; After the yarn collection is completed, the power supply of the electromagnet 47 is cut off, the magnetic field disappears, and the containing shell 42 resets relative to the ring plate 41 under the action of the elastic force of the spring three, and is separated from the area of the first clamp plate 35 and the second clamp plate 36, without affecting the subsequent feeding and detection actions; Through the air suction structure 44 of the collection assembly 4, the broken yarn can be collected and stored in the containing shell 42, compared with the blowing cleaning method in the prior art, the yarn is avoided from being blown into the sliding groove of the movable part (such as the sliding track of the clamping structure 21, the sliding gap of the guide rod, etc.), which causes the equipment to be stuck and worn, and the long-term stable operation of the equipment is ensured, and the maintenance cost is reduced.

[0032] As Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, the yarn tension detection device further comprises a position detection assembly 5, which comprises a clamping structure 51 mounted on the mounting plate 31, the clamping structure 51 comprising a third clamping plate 511 and a fourth clamping plate 512; a timer 52 mounted on the mounting plate 31; and a telescopic rod 53 mounted on the mounting plate 31, an end of the telescopic rod 53 being provided with a first plate 54, the first plate 54 being slidably provided with a second plate 55, and a switch 56 being mounted between the first plate 54 and the second plate 55, the switch 56 being used to control the opening and closing of the timer 52.

[0033] Specifically, the switch 56 is an elastic press switch 56, which is triggered when pressed and resets when no pressure is applied, and the switch 56 is electrically connected to the timer 52. After the first clamping plate 35 and the second clamping plate 36 move to one side of the slidingly assembled clamping structure 21, the third clamping plate 511 and the fourth clamping plate 512 of the position detection assembly 5 are controlled to clamp the yarn, so that the yarn is in a state of “movable but not out”, which lays a foundation for subsequent detection. After the tension detection is completed, the cylinder one 23 is controlled to reset, and the slidingly assembled clamping structure 21 is controlled to release the yarn, the telescopic rod 53 is controlled to extend, and the first plate 54 and the second plate 55 are driven to move forward. After the second plate 55 contacts the yarn, the first plate 54 continues to move forward, the second plate 55 remains stationary due to the obstruction of the yarn, the distance between the first plate 54 and the second plate 55 decreases, and the switch 56 between the first plate 54 and the second plate 55 is pressed. After the switch 56 is triggered, the timer 52 is immediately started, and the gear two 310 is controlled to rotate in reverse, driving the first clamping plate 35 and the second clamping plate 36 to rotate in reverse, thereby winding (pulling the yarn to move) the broken yarn. With the winding of the yarn by the first clamping plate 35 and the second clamping plate 36, the yarn gradually moves out of the clamping area of the third clamping plate 511 and the fourth clamping plate 512. When the yarn completely separates from the third clamping plate 511 and the fourth clamping plate 512, the second plate 55 loses the obstruction of the yarn, the switch 56 resets, and the timer 52 stops timing. Subsequently, the timer 52 transmits the recorded time data to the system; Subsequently, the mounting plate 31 is controlled to rotate in reverse to reset. After resetting, the first clamping plate 35, the second clamping plate 36, the third clamping plate 511 and the fourth clamping plate 512 clamp the yarn between the clamping structure 21 and the guide wheel, respectively. After clamping, the clamping structure 21 is controlled to release the yarn, and the above-mentioned triggering, timing and data transmission actions can be repeated; After the system receives the timer 52 data, the stretching length of the yarn between the two clamping structures 21 after the tension test is calculated in combination with the preset rotation speed of the gear two 310, and the breaking position of the yarn is calculated by comparing the time difference of the two detection timers 52. If the breaking position is close to a clamping structure 21, it means that the clamping force of the clamping structure 21 is too large, which may cause local damage to the yarn, resulting in inaccurate tension detection data. If the breaking position is in the middle of the yarn, it is determined that the tension detection data is accurate. The system can issue a prompt according to the judgment result, so that the staff can adjust the clamping force of the clamping structure 21 in time to ensure the accuracy of the subsequent detection results; Through the design of the position detection assembly 5, the quantitative calculation of the yarn stretching length and the accurate judgment of the breaking position are realized, forming a closed loop of detection, feedback and adjustment, which can timely find the yarn damage problem caused by excessive clamping force, eliminate the data error factors from the root, and further improve the reliability and accuracy of the detection results.

[0034] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 10 , the clamping structure 51 further comprises a connecting plate 513 and a third annular plate 514. The connecting plate 513 is fixedly installed on the mounting plate 31, and the third plate 515 is fixedly installed on the connecting plate 513. The third plate 515 is fixedly connected with the fourth clamping plate 512, and the third clamping plate 511 is slidingly connected on the third plate 515. The third annular plate 514 is rotatably installed on the mounting plate 31, and the round rod one 516 is threadedly connected on the third annular plate 514. The round rod one 516 is slidingly connected with the connecting plate 513, and the round rod two 517 is slidingly connected on the round rod one 516. The spring four is installed between the round rod one 516 and the round rod two 517, and the round rod two 517 is fixedly connected with the third clamping plate 511. The third annular plate 514 is fixedly installed with the gear four 518, and the rack plate 519 is fixedly installed on the machine body 1 to drive the rotation of the gear four 518.

[0035] Specifically, the round rod two 517 is movable relative to the round rod one 516, and the spring four provided therebetween provides a buffer force for both, so that after the third clamping plate 511 clamps the yarn, the yarn can slightly slide relative to the third clamping plate 511 and the fourth clamping plate 512 (to adapt to the stretching or movement requirement of the yarn). The thread between the third annular plate 514 and the round rod one 516 adopts a reciprocating thread; In the process of rotating the installation plate 31 to load, the gear four 518 is in contact with and engaged with the rack plate 519. Since the rack plate 519 is fixed on the machine body 1, the rotating force of the installation plate 31 makes the gear four 518 roll along the rack plate 519 and rotate, thereby driving the third annular plate 514 to rotate synchronously, driving the round rod one 516 to slide along the connecting plate 513 to the direction close to the installation plate 31, driving the round rod two 517 to move synchronously, thereby pulling the third clamping plate 511 to move away from the fourth clamping plate 512, so that the third clamping plate 511 and the fourth clamping plate 512 are in a loose claw state, and the yarn enters the reserved space. The installation plate 31 continues to rotate, the gear four 518 is disengaged from the first rack plate 519, and is in contact with and engaged with the second rack plate 519. The round rod one 516 slides along the connecting plate 513 to the direction away from the installation plate 31, driving the round rod two 517 and the third clamping plate 511 to move to the direction close to the fourth clamping plate 512. The yarn gradually enters between the third clamping plate 511 and the fourth clamping plate 512 in the process of rotating the installation plate 31. When the third clamping plate 511 is in contact with the yarn, the spring four is slightly compressed, and the third clamping plate 511 and the fourth clamping plate 512 clamp the yarn with appropriate force through the buffering force of the spring four.
