Description

Technical Field

[0001] The invention relates to a detection device and method for kapok blended yarn, belonging to the technical field of detection equipment. Background Art

[0002] Kapok, a natural fiber material, is widely used in the textile industry. Processed kapok creates fabrics that are light, soft, and hollow. During the fabric production process, the finished fabrics are typically tested for various indicators, such as air permeability, friction, and flame retardancy.

[0003] Current friction detection devices can usually only perform friction detection on fabrics in one direction. The data obtained after the detection is relatively simple and the detection direction is not comprehensive enough. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detection device and method for kapok blended yarn, which solves the problem of single fabric detection direction in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A detection device for kapok blended yarn comprises a base, one end of the base is provided with a clamping platform, and the other end is provided with a slide rail; A pressing plate, one end of which is slidably arranged on the slide rail and the other end of which is suspended in the air; A rotating disk is rotatably disposed on the clamping table, wherein the outer ring of the rotating disk is provided with a clamping assembly for clamping the blended yarn; A friction portion is provided at the suspended end of the pressing plate, and a friction gauze is fixed on one end of the friction portion facing the rotating disk; Control box, used to adjust the detection parameters during control detection; The pressing plate and the slide rail are connected via a connecting block, and a driving component for driving the connecting block to slide is provided on the connecting block.

[0006] By adopting the above technical solution, multi-angle friction detection of blended yarn can be achieved, and the detection surface is more comprehensive. By controlling the rotation of the rotating disk, when the friction part is attached to the blended yarn for friction testing, the blended yarn can be synchronously driven to rotate, so that the blended yarn can be subjected to friction testing at different angles and directions, thereby expanding the detection range and improving the detection effect.

[0007] The present invention is further configured as follows: the driving assembly includes a push-pull rod connected to the upper end of the connecting block, the other end of the push-pull rod extends toward the suspended end of the pressing plate and is rotatably connected to an eccentric handle at the end, the other end of the eccentric handle extends to the interior of the control box, and a driving source for driving the eccentric handle to rotate is provided inside the control box.

[0008] By adopting the above technical solution, the reciprocating sliding stroke of the connecting block can be accurately controlled. By controlling the rotation of the eccentric handle, the eccentric handle pulls the push-pull rod to move, thereby driving the connecting block to slide back and forth on the slide rail. The connecting block then drives the connected pressing plate to move, ultimately achieving the purpose of sliding the friction portion on the blended yarn. The provision of the eccentric handle, combined with the push-pull rod connected to the connecting block, can convert rotational power into linear thrust, thereby simplifying the structure of the entire drive component and enabling the pressing plate to achieve reciprocating motion with only a single drive motor.

[0009] The present invention is further configured as follows: the clamping assembly includes an extension portion extending from the rotating disk toward the outer ring, a rotating groove is provided on the rotating disk at the position of the extension portion, and a clamping plate is rotatably provided on the extension portion.

[0010] By adopting the above technical solution, the blended yarn to be tested can be quickly fixed on the rotating disk, thereby improving the detection efficiency. When fixing the blended yarn, the clamping plate is moved out of the rotating groove, the blended yarn is laid on the rotating disk, and the clamping plate is moved again to clamp the clamping plate into the rotating groove, so that the blended yarn is clamped in the rotating groove by the clamping plate, thereby achieving rapid clamping and fixing of the blended yarn.

[0011] The present invention is further configured such that: the end of the clamping plate is provided with a clamping portion whose size is smaller than the width of the rotating groove.

[0012] By adopting the above technical solution, the blended yarn can be stably fixed on the rotating disk. When the blended yarn is fixed, the clamping plate is moved so that the clamping portion at the end of the clamping plate can press the blended yarn into the rotating groove. The thickness of the blended yarn just fills the gap between the clamping portion and the rotating groove, thereby achieving rapid clamping and fixing of the blended yarn.

[0013] The present invention is further configured as follows: the upper end surface of the rotating disk is a smooth convex surface, the protrusion height in the middle is the highest and the height gradually decreases from the center of the middle circle to the outer circle.

[0014] By adopting the above technical solution, the device can perform more comprehensive detection on blended yarn. Through the setting of the protruding surface, after the blended yarn is laid on the turntable, when the friction part contacts the blended yarn for friction, the pressure applied by the friction part on the blended yarn varies due to the setting of different heights of the protruding surface. When the friction part moves to the highest point of the protruding surface, the pressure on the blended yarn is the greatest, and the friction force is also the greatest at this time. Conversely, when the friction part moves to the lowest point of the protruding surface, the friction force is the smallest. Friction detection of blended yarn under the action of different friction forces can more closely simulate the external friction loss of blended yarn during actual use, simulate more comprehensive detection conditions, and provide users with more comprehensive detection data.

[0015] The present invention is further configured such that: a plurality of pressure sensors are provided on the upper end surface of the rotating disk.

[0016] By adopting the above technical solution, a pressure sensor is used to monitor the stress condition of the blended yarn in real time during the detection process. Combined with the degree of damage to the surface of the blended yarn after monitoring, the degree of friction damage of the blended yarn under different stress states can be analyzed.

[0017] The present invention is further configured as follows: a through hole is provided at the suspended end of the pressing plate, the friction part is fixedly inserted into the through hole at the suspended end of the pressing plate by bolts, and a clamping sleeve is provided on the end facing the rotating disk, and the friction gauze is arranged on the friction part through the clamping sleeve.

[0018] By adopting the above technical solution, the friction part is fixed to the through hole of the pressing plate by bolts, which can be quickly installed or replaced without disassembling the entire pressing plate. The friction gauze can be quickly fixed to the friction part by the clamping sleeve, and the friction gauze can be quickly replaced during use, thereby improving detection efficiency.

[0019] The present invention is further configured such that a counterweight block is detachably provided on the suspended end of the pressing plate.

[0020] By adopting the above technical solution and selecting different counterweights, different detection pressures can be adjusted. The counterweight is set at the suspended end, close to the friction part, so that the friction part can be stably pressed against the rotating disk, preventing the friction part from separating from the rotating disk during the friction process, resulting in the inability to rub the blended yarn.

[0021] The present application also relates to a method for detecting kapok blended yarn, which specifically comprises the following steps: Step 1: Fix the blended yarn to be tested on the upper end surface of the rotating disk through the clamping assembly; Step 2: Put friction gauze on the friction part and select the corresponding counterweight block to install on the suspended end of the pressing plate; Step 3: Adjust the number of reciprocating movements through the control box, place the friction part against the blended yarn, and start the power supply; Step 4: while the friction part abuts against the blended yarn and performs reciprocating friction, the rotating disk is controlled to rotate synchronously; Step 5: Remove the blended gauze rubbed in step 4 from the rotating disk and observe the degree of damage. At the same time, remove the friction gauze on the friction part and observe the blended gauze adhered to the friction gauze.

[0022] By employing this technical solution and controlling the number of reciprocating friction cycles, we can simulate the damage to blended yarn under different friction conditions. The synchronous rotation of the rotating disc combined with the reciprocating motion of the friction unit simulates the complex multi-directional friction scenarios encountered in actual use, more realistically reflecting the wear resistance of blended yarn.

[0023] The beneficial effects of the present invention are: By setting the clamping table of the blended yarn in a freely rotatable form and coordinating the pressing plate, multi-directional and multi-angle friction test can be realized, which can simulate more complex scenarios and measure a variety of different friction scenarios.

[0024] By setting the upper end surface of the rotating disk into a convex shape and cooperating with the pressure sensors arranged in an array on the upper end surface of the rotating disk, the wear of the blended yarn under different pressure states can be detected. Combined with the rotatable rotating disk, the simulation scene is more complex, the detection parameters are more diversified, and the data obtained from the test is more comprehensive.

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further explained below with reference to specific illustrations.

[0028] like Figure 1As shown, a detection device for kapok blended yarn comprises a base 1, one end of the base 1 is provided with a clamping platform 2, and the other end is provided with a slide rail 3; one end of a pressing plate 4 is slidably set on the slide rail 3, and the other end is suspended; a rotating disk 5 is rotatably set on the clamping platform 2, and the outer ring of the rotating disk 5 is provided with a clamping component 6 for clamping the blended yarn; a friction part 7 is provided at the suspended end of the pressing plate 4, and a friction gauze is fixed on the end of the friction part 7 facing the rotating disk 5; a control box 8 is used to adjust the detection parameters during control detection; wherein, the pressing plate 4 and the slide rail 3 are connected by a connecting block 9, and the connecting block 9 is provided with a driving component for driving it to slide.

[0029] One end of the base 1 is circular with a central through-hole, while the other end is elongated with a central slide. The clamping platform 2 is fixedly connected to the base 1 through the through-hole in the circular end of the base 1, and the slide rail 3 is bolted into the slide groove at the elongated end of the base 1. A support foot is fixedly connected to the lower end of the elongated base 1. The distance between the bottom of the support foot and the bottom of the clamping platform 2 and the bottom of the base 1 is equal. The entire base 1 is supported and fixed by the clamping platform 2 and the support foot.

[0030] like Figure 2 As shown, the pressing plate 4 is connected to the slide rail 3 via a connecting block 9. A slider is fixedly connected to the bottom of the connecting block 9, which slides and engages with the slide rail 3. The connection point between the pressing plate 4 and the connecting block 9 is near the lower end of the connecting block 9. The pressing plate 4 is divided into an inclined section and a parallel section. The inclined section is the section at the connection end of the pressing plate 4 and the connecting block 9, and is inclined relative to the slide rail 3. The parallel section is the section of the suspended end of the pressing plate 4, and is parallel to the slide rail 3. The inclined section of the pressing plate 4 is made of elastic material, while the parallel section is made of rigid material.

[0031] By setting the connection point between the pressing plate 4 and the connecting block 9 near the lower end of the connecting block 9, which is close to the fixed connection point between the connecting block 9 and the slider, the center of gravity of the connection point between the pressing plate 4 and the connecting block 9 can be biased downward, thereby reducing the longitudinal pressure on the slider during the sliding process, improving the sliding smoothness of the slider, and reducing the wear of the slider. The parallel section is made of rigid material, and the friction part 7 is set on the parallel section, so that the friction part 7 can always remain relatively parallel to the slide rail 3 when rubbing the blended yarn in a reciprocating motion, thereby controlling the friction angle and avoiding excessive fluctuations in the angle between the friction part 7 and the fabric surface of the blended yarn, so that the detection device can more accurately simulate the degree of wear of the blended yarn when it is subjected to friction parallel to the fabric surface.

[0032] The control box 8 is provided with operating buttons for controlling the start and stop of the entire detection device and adjusting detection parameters.

[0033] like Figure 3As shown, the drive assembly includes a push-pull rod 10 connected to the upper end of the connecting block 9. The other end of the push-pull rod 10 extends toward the suspended end of the pressing plate 4 and is rotatably connected to an eccentric handle 11 at the end. The other end of the eccentric handle 11 extends into the interior of the control box 8. The control box 8 is provided with a drive source for driving the eccentric handle 11 to rotate. In this embodiment, the drive source is specifically a drive motor. The rotating shaft of the drive motor is directly and fixedly connected to the end of the eccentric handle 11 extending into the interior of the control box 8. The eccentric handle 11 is rotated by controlling the drive source, thereby quickly achieving reciprocating sliding of the connecting block 9, thereby driving the pressing plate 4 to move.

[0034] Specifically, the push-pull rod 10 is made of a rigid material, and the push-pull rod 10 and the connecting block 9 are rotatably connected. An overlap portion is provided at one end of the push-pull rod 10 connected to the eccentric handle 11, and a through hole is provided in the center of the overlap portion. The eccentric handle 11 includes an extension end extending to the interior of the control box 8, an eccentric plate vertically connected to the extension end, and a transfer end vertically connected to the other end of the eccentric plate. The transfer end directly passes through the central through hole of the overlap portion and is then snapped onto the overlap portion. The thickness of the overlap portion is less than the length of the transfer end. A socket is provided at the outer end of the transfer end, and a plug-in cover is plugged into the transfer end through the socket at its end. During installation, the transfer end is inserted into the through hole in the center of the overlap portion after removing the plug-in cover, and then the plug-in cover is installed to the transfer end to complete the installation. The plug-in cover can prevent the transfer end from being separated from the socket of the overlap end.

[0035] By providing the push-pull rod 10 and the eccentric handle 11, the connecting block 9 can be driven directly by the rotation of the motor to achieve sliding, thereby reducing the cost of the drive source of the entire device. At the same time, the push-pull rod 10 integrates the drive source of the pressing plate 4 into the control box 8, making the wiring between the drive source and the control box 8 more convenient and improving the integration of the entire device.

[0036] At the same time, the push-pull rod 10 converts the rotational power of the driving source into the sliding force of the pressing plate 4. When the driving source rotates one circle, the pressing plate 4 completes one reciprocating sliding movement, so that the device can accurately control the reciprocating sliding stroke of the connecting block 9. By controlling the rotation of the eccentric handle 11, the push-pull rod 10 is pulled to move during the rotation of the eccentric handle 11, thereby driving the connecting block 9 to slide back and forth on the slide rail 3. The connecting block 9 drives the pressing plate 4 connected to it to move, and finally achieves the purpose of sliding the friction part 7 on the blended yarn.

[0037] like Figure 3 As shown, the clamping assembly 6 includes an extension portion 601 extending outward from the rotating disk 5 , a rotation slot 602 is provided on the rotating disk 5 at the position of the extension portion 601 , and a clamping plate 603 is rotatably provided on the extension portion 601 .

[0038] There are at least two clamping assemblies 6 , and in this embodiment there are three clamping assemblies 6 , which are equidistantly arranged on the outer ring of the rotating disk 5 . A clamping portion 6031 smaller than the width of the rotating groove 602 is provided at the end of the clamping plate 603 .

[0039] The extension portion 601 is specifically two clamping plates, which extend from the rotating disk 5 to form a clamping gap for clamping the clamping plate 603. The clamping plate 603 is rotatably installed in the clamping gap, and the clamping gap is connected to the rotating groove 602. When the blended yarn needs to be fixed, the blended yarn is first laid on the rotating disk 5, and then the clamping plate 603 is rotated so that the clamping plate 603 presses one corner of the blended yarn into the rotating groove 602. The clamping portion 6031 is embedded in the rotating groove 602 to fix the corner of the blended yarn. The clamping plates 603 in other directions also clamp one corner of the blended yarn in the same way, thereby stably fixing the blended yarn on the rotating disk 5.

[0040] In this embodiment, a driving motor is provided inside the clamping table 2 for driving the entire rotating disk 5 to rotate. In other embodiments, the rotating disk 5 can also be rotated back and forth by manually holding the clamping assembly 6.

[0041] When the rotating disk 5 is driven by the driving motor, the overall driving speed of the rotating disk 5 is more stable, and the detection results are more stable. When the rotating disk 5 is rotated by manual operation, more diverse rotations can be achieved, and the rotation speed and rotation distance can be manually controlled, which makes the operation more convenient and can measure the friction detection effect of blended yarns under more rotation states.

[0042] like Figure 4 and Figure 5 As shown, in this embodiment, engaging wheels 6032 are provided at both ends of the engaging plate 603. A circular groove 6036 for mounting the engaging wheels 6032 is provided on the inner side of the clamping plate. A plurality of fixed rods 6033 are provided inside the engaging wheels 6032. Compression springs 6034 are sleeved on the fixed rods 6033. The compression springs 6034 are capable of pushing the fixed rods 6033 outward. Under normal conditions, the ends of the fixed rods 6033 are exposed outside the outer ring of the engaging wheel 6032. Within the inner ring of the circular groove 6036, a semicircular area is provided with an inwardly extending protrusion 6035. When the fixed rods 6033 on the engaging wheel 6032 rotate to the protrusion 6035, the exposed ends of the fixed rods 6033 are pressed into the interior of the engaging wheel 6032. When the engaging portion 6031 of the clamping plate 603 is engaged with the rotating groove 602 , the fixed rod 6033 is completely rotated to the area where the protrusion 6035 is provided in the circular groove 6036 .

[0043] By arranging the above-mentioned clamping wheel 6032, fixed rod 6033 and protrusion 6035, when the clamping portion 6031 of the clamping plate 603 is clamped in the rotating groove 602 to clamp and fix the blended yarn, the fixed rod 6033 abuts against the protrusion 6035, which can prevent the clamping plate 603 from shaking up and down due to the rotation of the rotating disk 5 during the clamping process, thereby stably clamping and fixing the blended yarn, thereby improving the stability of the blended yarn detection.

[0044] The free-standing end of the press plate 4 is provided with a through-hole, into which the friction portion 7 is fixedly inserted via bolts. A clamping sleeve is provided on the end facing the rotating disk 5, through which the friction gauze is attached to the friction portion 7. The clamping sleeve allows for quick and stable attachment of the friction gauze to the friction portion 7, facilitating operation. The entire friction portion 7 is bolted to the free-standing end of the press plate 4, facilitating subsequent replacement and maintenance.

[0045] The suspended end of the pressing plate 4 is detachably provided with a counterweight 12. By setting different counterweights 12, the friction force of the blended yarn can be adjusted, and the measurement simulation of the blended yarn under different stress conditions can be realized, so that different working condition tests can be carried out according to different test requirements, and the test data is more comprehensive.

[0046] like Figure 6 As shown, in another embodiment, the upper end surface of the rotating disk 5 is a smooth protruding surface 501, the protrusion height in the middle is the highest and the height gradually decreases from the center of the middle circle to the outer circle, and a plurality of pressure sensors are provided on the upper end surface of the rotating disk 5.

[0047] Adopt pressure sensor to carry out real-time monitoring to the stress situation of blended yarn in the detection process, combine the degree of damage on the blended yarn surface after monitoring, and then can analyze the friction damage degree under different stress states of blended yarn.By the setting of protruding surface 501, after blended yarn is laid on rotating disk, when friction portion 7 abuts on blended yarn and rubs, due to the setting of protruding surface different heights, the pressure size that friction portion 7 applies to blended yarn changes therewith, the pressure maximum that friction portion 7 produces to blended yarn when friction portion 7 moves to the highest point of protruding surface 501, and friction force now is also maximum, on the contrary, friction force is minimum when friction portion 7 moves to the lowest point of protruding surface 501.Blended yarn carries out friction detection under the effect of different friction forces, can be subjected to external friction loss when the simulation blended yarn that can fit more is actually used, simulates more comprehensive detection situation, provides more comprehensive detection data for user.

[0048] The present application also relates to a method for detecting kapok blended yarn, which specifically comprises the following steps: Step 1: Fix the blended yarn to be tested on the upper end surface of the rotating disk 5 through the clamping assembly 6; Step 2: Put friction gauze on the friction part 7, and select the corresponding counterweight block 12 to install it on the suspended end of the pressing plate 4; Step 3: Adjust the number of round trips through the control box 8, place the friction part 7 against the blended yarn, and start the power supply; Step 4: While the friction part 7 abuts against the blended yarn and performs reciprocating friction, the rotating disk 5 is controlled to rotate synchronously; Step 5: Remove the blended gauze rubbed in step 4 from the rotating disk 5 and observe the degree of damage. At the same time, remove the friction gauze on the friction part 7 and observe the blended gauze adhered to the friction gauze.

[0049] By adjusting the number of friction cycles, the wear and tear of the blended yarn can be simulated under different friction conditions. The synchronous rotation of the rotating disk 5 and the reciprocating motion of the friction part 7 simulate the complex multi-directional friction scenarios in actual use, more realistically reflecting the wear resistance of the blended yarn.

[0050] Working principle: The blended yarn to be tested is laid on the rotating disk 5, and the clamping plate 603 is rotated so that the clamping portion 6031 presses the corners of the blended yarn into the rotating groove 602. The clamping plate 603 is fixed by the friction between the fixed rod 6033 and the protrusion 6035, which can prevent the clamping plate 603 from shaking during the rotation of the rotating disk. After the friction yarn is fixed on the friction portion 7, the friction portion 7 is brought into contact with the blended yarn on the rotating disk 5, and the pressing plate 4 is driven to reciprocate. At the same time, the rotating disk 5 is rotated by manual or motor control, so that the damage of the blended yarn caused by friction at various angles can be simulated, achieving a more comprehensive detection of the blended yarn.

[0051] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and improvements are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
