[0039] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other.

[0040] Composite materials are formed by winding, molding or pultruding a reinforcing fiber material, such as glass fiber, carbon fiber, aramid fiber, etc., with a matrix material. According to the different reinforcing materials, common fiber-reinforced composite materials are divided into glass fiber-reinforced composite materials (GFRP), carbon fiber-reinforced composite materials (CFRP), and aramid fiber-reinforced composite materials (AFRP). Due to their advantages of high specific strength, high specific modulus, good corrosion resistance, and light weight, they are increasingly widely used in various fields such as civil buildings, bridges and highways, aerospace, etc.

[0041] During the process of making composite materials, fibers need to pass through a yarn guiding device, and fuzz will be generated when they rub against the yarn guiding device. The amount of fuzz generated during the use of fibers is an important parameter for evaluating fiber quality. Therefore, it is necessary to test the amount of fuzz before putting them into use. However, the current fuzz testing equipment has a single testing module and cannot simulate the different usage conditions of different fibers, resulting in inaccurate test results.

[0042] To solve the above problems, the present application provides a fuzz testing equipment. By setting a testing module in the box body of the collecting device, the testing module includes a mounting seat and multiple testing units. The mounting seat is detachably connected to the box body, and the multiple testing units are arranged at intervals along the first direction on the mounting seat. The yarn passes through the first through hole of the box body, passes through the multiple testing units, and then passes out through the second through hole. When it is necessary to test yarns of different types or different usage conditions, only by disassembling the mounting seat can the adapted testing module be replaced as a whole, which is convenient for simulating the actual usage conditions to test the amount of fuzz generated, and improves the accuracy of the test results.

[0043] The following will describe in detail the fuzz testing equipment provided according to the present application with reference to the accompanying drawings.

[0044] It should be noted that Figures 1 to 5 the x-axis direction in [reference figure] is the first direction, the y-axis direction is the second direction, and the z-axis direction is the vertical direction. In addition, the yarns in the present application, such as carbon fiber raw yarns, glass fiber raw yarns, or water-blocking yarns, etc., are all within the protection scope of the present application.

[0045] An exemplary embodiment of the present application provides a fuzz testing equipment, as shown in Figure 1 and Figure 2As shown in the figure, the hairiness testing device includes a frame 200, a collecting device 100, an unwinding device 300, and a winding device 400. The frame 200 includes a first tabletop 210 and a second tabletop 220 that are spaced apart in the vertical direction. A cabinet door 230 perpendicular to the second direction is connected between the first tabletop 210 and the second tabletop 220, so that a cavity that can be opened and closed by the cabinet door 230 is enclosed between the first tabletop 210 and the second tabletop 220. The collecting device 100, the unwinding device 300, and the winding device 400 are all arranged on the first tabletop 210 of the frame 200.

[0046] Among them, the collecting device 100 includes a box body 110 and a testing module. On two side walls of the box body 110 arranged opposite to each other in the first direction, a first through hole 1110 and a second through hole 1120 are respectively opened. A wire guiding structure 1111 is installed on the outer surface corresponding to the side wall where the first through hole 1110 is opened. The wire guiding structure 1111 is used to guide the yarn. The wire guiding structure 1111 is, for example, a combination of a magnetic eye and a roller. The testing module includes a mounting seat and multiple testing units. The mounting seat is detachably installed in the box body 110 and extends in the first direction. The multiple testing units are arranged at intervals in the first direction on the mounting seat. The yarn enters the collecting device 100 through the first through hole 1110, and after passing through the testing module, it passes out of the collecting device 100 through the second through hole 1120.

[0047] By arranging a testing module in the box body 110 of the collecting device 100, the testing module includes a mounting seat and multiple testing units. The mounting seat is detachably connected to the box body 110. The multiple testing units are arranged at intervals in the first direction on the mounting seat. The yarn passes through the first through hole 1110 of the box body 110 and passes out through the second through hole 1120 after being tested by the multiple testing units. When it is necessary to test yarns of different types or under different working conditions, only by disassembling the mounting seat can the adapted testing module be replaced as a whole, which is convenient for simulating the actual working conditions to conduct the hairiness amount test and improves the accuracy of the test results.

[0048] In some embodiments, as Figure 3 shown, the testing module is a magnetic eye 1230 testing module 120. The magnetic eye 1230 testing module 120 includes: a first mounting seat 1210, a cross beam 1220, a magnetic eye 1230, an angle adjusting member 1240, and an adjusting through hole 1250. The first mounting seat 1210 in this embodiment includes four side walls that together enclose a rectangular cavity. The cross beam 1220 is installed inside the first mounting seat 1210. The first mounting seat 1210 is fixedly connected to the box body 110 through a first fastener.

[0049] On two side walls of the first mounting base 1210, a plurality of groups of adjustment through holes 1250 corresponding to the cross beams 1220 one by one are oppositely provided. The adjustment through holes 1250 are in the shape of long strips extending along the first direction. The second fastener passes through the adjustment through holes 1250 and the through holes at both ends of the cross beam 1220 along the second direction, so as to realize the sliding connection and fixation between the cross beam 1220 and the first mounting base 1210; the fastener is, for example, a bolt and a nut. When the nut is loosened, the cross beam 1220 can slide along the direction of the adjustment through hole 1250. When the nut is tightened, the cross beam 1220 is fixed on the first mounting base 1210. A plurality of cross beams 1220 extend along the second direction and are arranged at intervals along the first direction. A plurality of magnetic eyes 1230 correspond to the plurality of cross beams 1220 one by one, that is, one magnetic eye 1230 is installed on each cross beam 1220. The magnetic eye 1230 can slide relative to the corresponding cross beam 1220 along the second direction. The connection manner between the magnetic eye 1230 and the cross beam 1220 can adopt the connection manner between the cross beam 1220 and the mounting base for sliding and fixation. In other embodiments, other connection manners can also be adopted, which will not be elaborated here.

[0050] The angle adjustment member 1240 is arranged at one end of the mounting base close to the first through hole 1110. The angle adjustment member 1240 is used to limit and adjust the angle at which the yarn penetrates into the magnetic eye 1230. In this embodiment, the angle adjustment member 1240 is composed of a plurality of metal rods extending along the second direction and arranged at intervals in the vertical direction. The angle at which the yarn penetrates into the magnetic eye 1230 is adjusted by adjusting through which two adjacent metal rods the yarn passes. The magnetic eye 1230 test module 120 further includes a plurality of first mounting holes 1260, and the first mounting holes 1260 are used for the fastener to pass through to realize the installation of the angle adjustment member 1240 or the side wall on the mounting base.

[0051] By arranging the cross beam 1220 and the magnetic eye 1230 with adjustable positions on the first mounting base 1210, it is convenient to adjust the position of the magnetic eye 1230 to simulate the actual working conditions when the magnetic eye 1230 is used as a yarn guiding device; by arranging the angle adjustment member 1240, the adjustment of the angle at which the yarn penetrates into the first magnetic eye 1230 (the magnetic eye 1230 closest to the first through hole 1110 at one end in the first direction) is realized, ensuring the accuracy of the test results.

[0052] In another embodiment, the angle adjustment member 1240 includes a rod with adjustable height in the vertical direction, which is also a solution that can realize angle adjustment.

[0053] In some embodiments, such as Figure 4As shown, the test module is the yarn guide rod 1320 test module 130. The yarn guide rod 1320 test module 130 includes a second mounting base 1310 and a plurality of yarn guide rods 1320. Among them, the second mounting base 1310 is detachably connected to the box body 110 through a third fastener. The second mounting base 1310 is a cavity enclosed by four side walls, and multiple yarn guide rods 1320 are installed in the second mounting base 1310. Each yarn guide rod 1320 extends along the second direction and is arranged at intervals along the first direction. The yarn guide rod 1320 can move in the vertical direction. It should be noted that the operators in this field can adjust the position of the yarn guide rod 1320 in the vertical direction according to the actual usage situation, and each yarn guide rod 1320 does not necessarily need to be flush in the vertical direction. This is convenient for simulating the actual usage conditions and improves the accuracy of the hairiness measurement.

[0054] The yarn guide rod 1320 test module 130 further includes a plurality of second mounting holes 1330. The fasteners pass through the second mounting holes 1330 to achieve the fixed connection between the side walls.

[0055] In some other embodiments, the test module can also be other test modules except the yarn guide rod 1320 test module 130 and the magnetic eye 1230 test module 120. With such a design, different test modules can be replaced by disassembling the mounting base, simulating various usage conditions, and the whole can be installed and disassembled, which is convenient, fast, and saves operation time.

[0056] In some embodiments, with continued reference to Figure 2 , the collecting device 100 further includes a funnel 140, a collecting box 150, and a blower 160. The funnel 140 and the collecting box 150 are both installed in the box body 110, and the blower 160 is installed on the second table surface 220 of the frame 200. The wide mouth end 1410 of the funnel 140 is arranged below the test module, and the wide mouth end 1410 covers at least all the test units to ensure that all the hairiness that drops after passing through the test units falls into the funnel 140. The narrow mouth end 1420 is communicated with the upper end of the collecting box 150, and the lower end of the collecting box 150 is communicated with the air inlet 1610 of the blower 160.

[0057] The hairiness collection process of the above-mentioned collecting device 100 is as follows:

[0058] The fan 160 starts, sucks away the air inside the box body 110 through the air inlet 1610. Under the action of the air pressure difference, the outside air enters the box body 110 through the air inlet 1140 on the box body 110. The overall air flow direction inside the box body 110 is from top to bottom, causing the fluff dropped from the yarn to be tested on the test unit to move downward, enter the funnel 140 from the wide mouth end 1410, and then enter the collection box 150 from the narrow mouth end 1420, completing the collection of fluff. After the collection is completed, the collection box 150 is pulled out through the handle 1510 provided on the collection box 150 for weighing.

[0059] The collection sponge is a consumable and needs to be replaced. With such a design, the collection box 150 is used instead of the traditional collection sponge, eliminating the need for regular replacement, reducing raw material costs, and avoiding waste.

[0060] In some embodiments, the bottom of the collection box 150 includes a mesh structure. The air inlet 1610 of the fan 160 is connected to the mesh structure. The mesh structure allows air to flow through while blocking the fluff in the collection box from passing through, enabling the air in the box body 110 to circulate, enter the box body 110 from the air inlet 1140, and leave the box body 110 from the mesh structure of the collection box 150.

[0061] In some embodiments, as Figure 1 and Figure 2 shown, the unwinding device 300 and the winding device 400 are respectively arranged on both sides of the collection device 100 along the first direction. The unwinding device 300 is installed on the first bracket 330, and the winding device 400 is installed on the second bracket 440. The unwinding device 300 is used for unwinding the yarn, and the winding device 400 is used for winding the yarn.

[0062] In some embodiments, as Figure 2 shown, the unwinding device 300 includes a first magnetic powder brake 310 and an unwinding air shaft 320. The unwinding air shaft 320 is connected to the output end of the first magnetic powder brake 310. The first magnetic powder brake 310 controls the rotation of the unwinding air shaft 320 to achieve the unwinding of the yarn.

[0063] In some embodiments, continuing to refer to Figure 2 , the winding device 400 includes a second magnetic powder brake 410 and a winding air shaft 420. The winding air shaft 420 is connected to the output end of the second magnetic powder brake 410. The second magnetic powder brake 410 controls the rotation of the winding air shaft 420 to achieve the winding of the yarn.

[0064] The magnetic powder brake is a braking device that fills the working gap between the stator and the rotor with magnetic powder, transfers power and motion through the bonding force between the magnetic powder generated by electromagnetic suction and the frictional force between the magnetic powder and the working surface, and can control and adjust the torque. Its exciting current and transmitted torque are basically linearly related. It can transmit a certain torque regardless of the slip, and has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration, and energy saving, improving the tension control accuracy and winding and unwinding speed during the yarn winding and unwinding process.

[0065] In this embodiment, the winding device 400 further includes a wire guiding mechanism 430. The wire guiding mechanism 430 is installed on the first table surface 210 and is located between the collecting device 100 and the winding device 400. The wire guiding mechanism 430 is installed on the third bracket 4360, and the moving direction of the wire guiding mechanism 430 is parallel to the axial direction of the winding air shaft 420. By providing the wire guiding mechanism 430, the yarn can be evenly wound around the winding air shaft 420 under the guidance of the wire guiding mechanism 430 during winding.

[0066] In some embodiments, as Figure 5 shown, the wire guiding mechanism 430 includes a cylinder 4310, a guide rail, a slider 4320, a roller 4330, and a limiting structure 4340. Among them, the guide rail extends along the second direction. The cylinder 4310 is installed on the outer side of one side of the guide rail along the second direction. The slider 4320 is slidably connected to the guide rail. The output end of the cylinder 4310 is fixedly connected to the slider 4320 to drive the slider 4320 to move on the guide rail. An installation plate is fixed on the upper surface of the slider 4320. One end of the installation plate close to the winding air shaft 420 protrudes from the guide rail. The limiting structure 4340 and the roller 4330 are installed on the installation plate.

[0067] It should be noted that the limiting structure 4340 in this embodiment is the magnetic eye 1230. The limiting structure 4340 can also be set to other new through-hole structures, etc. In addition, two limiting structures 4340 and two rollers 4330 are provided in this embodiment. In other embodiments, the setting methods of the limiting structure 4340 and the roller 4330 can be, for example, one limiting structure 4340 and one roller 4330, two limiting structures 4340 and one roller 4330, etc., all within the protection scope of this application.

[0068] The wire guiding process of the above wire guiding mechanism 430 is as follows:

[0069] After the yarn passes through the collecting device 100, it passes through the limiting structure 4340, passes over the surface of the roller 4330, then passes through another limiting structure 4340, and then passes over the surface of another roller 4330 before being fixed to the surface of the winding air shaft 420. The cylinder 4310 is started, and the slider 4320 begins to reciprocate along the second direction on the guide rail, and the uniform winding of the yarn on the winding air shaft 420 is realized during the movement.

[0070] The wire guiding mechanism 430 in this embodiment realizes relatively accurate limiting of the yarn, and the setting of the roller 4330 also reduces friction, thereby ensuring the uniformity of winding without damaging the yarn.

[0071] In some embodiments, the hairiness testing device further includes a tension controller 500. The tension controller 500 is installed on the frame 200 and is electrically connected to both the first magnetic powder brake 310 and the second magnetic powder brake 410. The setting of the tension controller 500 enables the first magnetic powder brake 310 and the second magnetic powder brake 410 to unwind and wind the yarn at a constant tension, improving the control accuracy of the tension of the yarn.

[0072] The usage process of the above hairiness testing device is as follows:

[0073] Step 1: Install the test module. Select the corresponding test module according to the type of the yarn to be tested and its actual usage conditions, and install the mounting seat of the test module in the box body 110 through fasteners.

[0074] Step 2: Install the yarn. Fix the yarn bobbin on the unwinding air shaft 320, and fix one end of the yarn to the paper tube on the winding air shaft 420 after passing through the first through hole 1110, multiple test units, the second through hole 1120, the limiting structure 4340, and the roller 4330 in sequence. Adjust the positions of the test units in all directions according to the actual usage conditions (this adjustment can also be performed before installing the yarn).

[0075] Step 3: Start the test. Start the tension controller 500, and the first magnetic powder brake 310 and the second magnetic powder brake 410 control the synchronous rotation of the unwinding air shaft 320 and the winding air shaft 420, so that the yarn passes through the test module at a constant tension and a constant speed; start the fan 160 and the wire guiding mechanism 430 to start collecting hairiness. The operator can observe the collection situation through the window 1130 on the box body 110.

[0076] Step 4: Obtain the test result. After the test is completed, take out the collection box 150, weigh the collection box 150 and the collected hairiness as a whole, and subtract the weight of the collection box 150 to obtain the amount of hairiness generated corresponding to the yarn.

[0077] The hairiness testing device provided by the present application sets a testing module in the box body 110 of the collecting device 100. The testing module includes a mounting seat and a plurality of testing units. The mounting seat is detachably connected to the box body 110. When it is necessary to test yarns of different types or under different operating conditions, only by disassembling the mounting seat can the adapted testing module be replaced as a whole, which is convenient for simulating the actual operating conditions to test the hairiness generation amount. The arrangement of the wire mechanism 430 improves the uniformity of the yarn winding on the paper tube. By setting the collecting box 150, it is not necessary to use a collecting sponge during collection, reducing waste. The above arrangements all improve the accuracy of the test results, while saving raw material costs and equipment costs.

[0078] The content described above can be implemented alone or in various combinations, and these variant ways are all within the protection scope of the present application.

[0079] It should be noted that in the description of the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0080] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.
