Description

[0001] The present invention is a divisional application of 2024108687133, a textile yarn performance detection device and a detection method thereof. Technical Field

[0002] The invention relates to the technical field of knitwear production, and more specifically to a spinning performance detection device and a detection method thereof. Background Art

[0003] There are many types of knitwear, such as carpets, sofa covers, chairs, tapestries, patches, towels, tea towels, tablecloths, handkerchiefs, bed sheets, quilt covers, quilt covers, blankets, towel quilts, etc. The raw materials of these products are all woven with yarn, and good products also have requirements on the quality of the yarn.

[0004] Knitted fabrics are woven from yarns, and the yarns often need to be tested for tensile strength before they are woven. However, some existing yarn tensile strength testing devices require the yarns to be wrapped multiple times from both ends before they can be fixed, which is troublesome. In addition, at the moment of breaking, the yarns will be thrown out like a whip. Although there may not be a large external force generated, it will bring certain psychological pressure to the on-site staff, which is not conducive to the staff to observe the stretched state and situation of the yarns at a closer distance. Summary of the invention

[0005] The object of the present invention is to provide a spinning performance detection device and a detection method thereof to solve the problems raised in the above background technology:

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Preferably, the protective mechanism includes a rotating rod, which is rotatably connected to the detection shell. There are two rotating rods in total, and the two rotating rods are symmetrically distributed. A protective plate is fixedly connected to the outside of the rotating rod, and the protective plate is a transparent plate. Even if the two protective plates are in contact and closed, it will not affect the staff's observation and recording of the yarn being pulled.

[0009] Preferably, the transmission mechanism includes a turntable, which is rotatably connected to the detection shell, and a connecting rod is rotatably connected between the turntable and the first slider, a third slide groove is provided inside the detection shell, a slide plate is slidably connected inside the third slide groove, a fourth slide groove is provided inside the slide plate, a second slide rod is slidably connected inside the fourth slide groove, the second slide rod is fixedly connected to the turntable, corresponding two side edges of the slide plate are fixedly connected to racks, the outside of the rotating rod is fixedly connected to a gear, the gear and the rack are meshed and connected, and the fourth slide groove is a semi-circular arc structure. When the two first sliders move away from each other, the first slider will drive the turntable to rotate through the connecting rod, and the turntable squeezes the inner wall of the fourth slide groove through the second slide rod, thereby pushing the slide plate to move. When the slide plate moves to the fourth slide groove until the center of the circle coincides with the center of the circle of the turntable, even if the turntable continues to rotate, the second slide rod only slides on the inner side of the fourth slide groove of the semi-circular arc structure without squeezing the inner wall of the fourth slide groove. At this time, the slide plate no longer moves, and the two protective plates outside the detection shell have also been contacted and closed.

[0010] Preferably, the second slider is internally slidably connected to a first guide rod, the first guide rod is fixedly connected to the first slider, a first spring is sleeved on the outside of the first guide rod and located between the second slider and the first slide groove, the first guide rod limits the second slider, and the elastic force of the first spring helps the two clamping blocks to approach each other to clamp the yarn.

[0011] Preferably, the interior of the slide plate is slidably connected to a second guide rod, the second guide rod is fixedly connected to the detection housing, and the second guide rod limits the slide plate to ensure that the slide plate can move smoothly in the third slide groove.

[0012] Preferably, a second groove is provided inside the detection housing, and the second groove is used in conjunction with the rack. The second groove is used to accommodate the rack to prevent the rack from being stuck against the inner wall of the detection housing.

[0013] Preferably, a third groove is provided inside the clamping block, and there are two third grooves in total, and the two third grooves are symmetrically distributed. A baffle rod is slidably connected inside the third groove, and a second spring is provided between the baffle rod and the third groove, and one end of the second spring is fixedly connected to the baffle rod, and the other end of the second spring is fixedly connected to the clamping block. When the two clamping blocks are in a state of moving away from each other, the elastic force of the second spring will make the baffle rod be located in the gap between the two clamping blocks. After the staff places the two ends of the yarn between the two clamping blocks, the yarn can be placed on the baffle rod, so that the yarn can be maintained in the center position between the two clamping blocks after being clamped, thereby ensuring the clamping effect of the two clamping blocks on the yarn.

[0014] Preferably, a tooth groove is provided on one side of the interior of the clamping block close to the bidirectional screw rod. When the two clamping blocks clamp the yarn, the tooth grooves on the sides of the two blocks engage with each other, so that the yarn is clamped in a serrated shape, thereby increasing the contact area between the yarn and the clamping block and preventing the yarn from detaching from the clamping block.

[0015] Preferably, a control panel is fixedly connected to the outside of the detection housing on a side away from the motor, the motor is electrically connected to the control panel, and the electrical equipment is powered by the mains and controlled by the control panel.

[0016] A detection method of a spinning performance detection device comprises the following steps:

[0017] Step 1: The staff puts the yarn to be tested on the detection shell, and places the two ends of the yarn between the two clamping blocks at different positions on both sides, and starts the motor forward through the control panel. The motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two first sliders to move simultaneously and move away from each other. During the process, the first slider is squeezed by the inner wall of the first groove and slides toward the direction close to the bidirectional screw. The first slider drives the two clamping blocks to approach each other through the second slider to clamp the yarn. As the two first sliders continue to move away from each other, the yarn is straightened. At this time, the staff records it, and records it again after the yarn is broken. The two recorded data are compared to complete the test of the yarn's tensile strength. This is the working principle of the spinning performance detection device. At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field. Start the motor reversely to drive the first slider back, and the two clamping blocks move away from each other, release the clamping of the yarn, and take out the broken yarn.

[0018] Step 2: When the two first sliders move away from each other, the turntable will be driven to rotate through the connecting rod, and the turntable will drive the second slider to do circular motion, so that the second slider squeezes the inner wall of the fourth slide groove, thereby pushing the slide plate to move away from the bidirectional screw rod. The slide plate then drives the rotating rod to rotate through the rack and gear. The rotating rod finally drives the two protective plates to flip upward and approach each other until the two protective plates are in contact and closed. The protective plates can protect the yarn when it is pulled to prevent it from being suddenly thrown out when the yarn breaks, thereby ensuring safety.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) When the spinning performance testing device is in use, the staff places the two ends of the yarn between two clamping blocks at different positions on both sides, and starts the motor through the control panel to drive the bidirectional screw to rotate forward. The bidirectional screw drives the two first sliders to move simultaneously and move away from each other. During the process, the first slider is squeezed by the inner wall of the first groove and slides toward the direction close to the bidirectional screw. The first slider drives the two clamping blocks to move closer to each other through the second slider to clamp the yarn. As the two first sliders continue to move away from each other, the yarn is straightened until the yarn is broken. There is no need for the staff to wrap and fix the two ends of the yarn multiple times, and the operation is more convenient.

[0021] 2) When the spinning performance testing device is in use, during the process of pulling the yarn, the first slider will drive the turntable to rotate through the connecting rod, the turntable will drive the slide plate to move through the second slide bar and the fourth slide groove, the slide plate will then drive the rotating rod to rotate through the rack and gear, and the rotating rod will finally drive the two simultaneous protective plates to flip upward to close, so that the protective plates can protect the yarn when it is pulled, prevent the yarn from suddenly being thrown out when it breaks, ensure safety, and help the staff to observe the yarn at a closer distance.

The first groove 10 is used in conjunction with the first slide bar 9. The first groove 10 consists of two parts, one is an inclined groove and the other is a straight groove. The straight groove is parallel to the bidirectional screw rod 3. When the first slide bar 9 is located in the inclined groove, if the first slide block 4 moves, the first slide bar 9 will be squeezed by the inner wall of the inclined groove. , so that the first slide bar 9 can drive the clamping block 8 to move through the second slide block 7, and the yarn is automatically clamped by the clamping block 8, which saves the staff from manually winding the yarn for fixing it many times. A protective mechanism 11 is arranged on the outside of the detection shell 1, and a transmission mechanism 12 is arranged on the inside of the detection shell 1. The transmission mechanism 12 is used to transmit power to the protective mechanism 11, and the protective plate 1102 in the protective mechanism 11 is used to protect the yarn during the pulling process, which helps the staff to observe and record the stretched state of the yarn at a closer distance.

[0032] Furthermore, the protective mechanism 11 includes a rotating rod 1101, which is rotatably connected to the detection shell 1. There are two rotating rods 1101, and the two rotating rods 1101 are symmetrically distributed. The outside of the rotating rod 1101 is fixedly connected with a protective plate 1102, and the protective plate 1102 is a transparent plate. Even if the two protective plates 1102 are in contact and closed, it will not affect the staff's observation and recording of the yarn being pulled, and at the moment the yarn breaks, the thrown yarn can be blocked by the protective plate 1102, which helps to reduce the psychological pressure of the staff when observing at a closer distance.

[0033] Furthermore, the transmission mechanism 12 includes a turntable 1201, which is rotatably connected to the detection shell 1, and a connecting rod 1202 is rotatably connected between the turntable 1201 and the first slider 4. A third slide groove 1203 is provided inside the detection shell 1, and a slide plate 1204 is slidably connected inside the third slide groove 1203. A fourth slide groove 1205 is provided inside the slide plate 1204, and a second slide bar 1206 is slidably connected inside the fourth slide groove 1205. The second slide bar 1206 is fixedly connected to the turntable 1201, and racks 1208 are fixedly connected to the corresponding two side edges of the slide plate 1204. A gear 1207 is fixedly connected to the outside of the rotating rod 1101, and the gear 1207 is meshed with the rack 1208. The fourth slide groove 1205 is a semicircular arc structure. When the two first sliders 4 move away from each other, the first slider 4 will move through the connecting groove The connecting rod 1202 drives the turntable 1201 to rotate, and the turntable 1201 squeezes the inner wall of the fourth slide groove 1205 through the second slide bar 1206, thereby pushing the slide plate 1204 to move. When the slide plate 1204 moves to the fourth slide groove 1205, the center of the circle coincides with the center of the circle of the turntable 1201, even if the turntable 1201 continues to rotate, the second slide bar 1206 only slides on the inner side of the fourth slide groove 1205 of the semi-circular arc structure without squeezing the inner wall of the fourth slide groove 1205. At this time, the slide plate 1204 no longer moves, and the two protective plates 1102 outside the detection shell 1 have also been contacted and closed to protect the pulled yarn. Through the setting, when the second slide bar 1206 slides on the inner side of the fourth slide groove 1205 of the semi-circular arc structure, it will not drive the protective plate 1102 to rotate, which is convenient for the subsequent normal pulling of the yarn by the first slider 4.

[0034] Furthermore, the second slider 7 is internally slidably connected to a first guide rod 13, the first guide rod 13 is fixedly connected to the first slider 4, and a first spring 14 is sleeved on the outside of the first guide rod 13 and located between the second slider 7 and the first slide groove 5. The first guide rod 13 limits the second slider 7, and the elastic force of the first spring 14 helps the two clamping blocks 8 to approach each other to clamp the yarn, so that the two clamping blocks 8 always have a tendency to approach each other.

[0035] Furthermore, the inside of the slide plate 1204 is slidably connected to a second guide rod 15, and the second guide rod 15 is fixedly connected to the detection shell 1. The second guide rod 15 limits the slide plate 1204 to ensure that the slide plate 1204 can move smoothly in the third slide groove 1203 and prevent the slide plate 1204 from being separated from the third slide groove 1203.

[0036] Furthermore, a second groove 16 is provided inside the detection housing 1 , and the second groove 16 cooperates with the rack 1208 . The second groove 16 is used to accommodate the rack 1208 to prevent the rack 1208 from being stuck against the inner wall of the detection housing 1 .

[0037] Furthermore, a third groove 17 is opened inside the clamping block 8. There are two third grooves 17, and the two third grooves 17 are symmetrically distributed. A baffle rod 18 is slidably connected inside the third groove 17. A second spring 19 is arranged between the baffle rod 18 and the third groove 17. One end of the second spring 19 is fixedly connected to the baffle rod 18, and the other end of the second spring 19 is fixedly connected to the clamping block 8. When the two clamping blocks 8 are in a state of moving away from each other, the elastic force of the second spring 19 will make the baffle rod 18 located in the gap between the two clamping blocks 8. After the staff puts the two ends of the yarn between the two clamping blocks 8, the yarn can be placed on the baffle rod 18, so that the yarn can be maintained in the center position between the two clamping blocks 8 after being clamped, thereby ensuring the clamping effect of the two clamping blocks 8 on the yarn.

[0038] Furthermore, a tooth groove 20 is provided on one side of the inside of the clamping block 8 close to the bidirectional screw rod 3. When the two clamping blocks 8 clamp the yarn, the tooth grooves 20 on the sides of the two clamping blocks 8 engage with each other, so that the yarn is clamped in a serrated shape, thereby increasing the contact area between the yarn and the clamping block 8 and preventing the yarn from detaching from the clamping block 8.

[0039] Furthermore, a control panel 21 is fixedly connected to the outside of the detection housing 1 on the side away from the motor 2. The motor 2 is electrically connected to the control panel 21. The electrical equipment is powered by the mains. It is a well-known technology to control the forward and reverse rotation of the motor 2 through the control panel 21, which will not be elaborated in detail.

[0040] A detection method of a spinning performance detection device comprises the following steps:

[0041] Step 1: The staff puts the yarn to be tested on the detection housing 1, and places the two ends of the yarn between the two clamping blocks 8 at different positions on both sides, and starts the motor 2 to rotate forward through the control panel 21. The motor 2 drives the bidirectional screw rod 3 to rotate, and the bidirectional screw rod 3 drives the two first sliders 4 to move simultaneously and move away from each other. During the process, the first slide bar 9 is squeezed by the inner wall of the first groove 10 and slides toward the direction close to the bidirectional screw rod 3. The first slide bar 9 drives the two clamping blocks 8 to move closer to each other through the second slide bar 7 to clamp the yarn. As the two first sliders 4 continue to move away from each other, the yarn is straightened. At this time, the staff records it, and after the yarn is broken, it records it again, and compares the two recorded data to complete the detection of the yarn's tensile strength. This is the working principle of the spinning performance detection device. At the same time, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. Start the motor 2 to reverse and drive the first slider 4 to return, and the two clamping blocks 8 move away from each other, release the clamping of the yarn, and take out the broken yarn.

[0042] Step 2: When the two first sliders 4 move away from each other, the turntable 1201 is driven to rotate through the connecting rod 1202, and the turntable 1201 drives the second slider 1206 to do circular motion, so that the second slider 1206 squeezes the inner wall of the fourth slide groove 1205, thereby pushing the slide plate 1204 to move away from the bidirectional screw rod 3, and the slide plate 1204 then drives the rotating rod 1101 to rotate through the rack 1208 and the gear 1207. The rotating rod 1101 finally drives the two protective plates 1102 to flip upward and approach each other until the two protective plates 1102 are in contact and closed. The protective plates 1102 are used to protect the yarn when it is pulled to prevent it from suddenly swinging outward when the yarn breaks, thereby ensuring safety.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
