Description

Technical Field

[0001] The invention belongs to the technical field of yarn testing, and in particular relates to an online yarn quality detection device. Background Art

[0002] Using a strength meter to test the strength of yarn is a common quality control method in the textile industry. According to the type, thickness and expected strength range of the yarn, a strength meter with appropriate range and accuracy should be selected. For example, for fine yarn, an electronic strength meter with higher accuracy and relatively smaller range can be selected; for coarse yarn or yarn with greater strength, a strength meter with a larger range needs to be selected.

[0003] However, when the yarn is subjected to tensile strength test by means of a tensile strength tester, the yarn with a fixed number of strands is usually fixed on the clamps on both sides of the tensile strength tester, and the tensile force is applied until the yarn breaks to complete the strength test; if the number of strands of the yarn needs to be increased or the woven yarn needs to be subjected to tensile strength test, the yarn needs to be woven by external equipment and then fixed on the tensile strength tester for testing, which is complicated and cumbersome, not only prolonging the test time, but also increasing the workload of yarn processing.

[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0029] like Figure 1-Figure 6 As shown, an online yarn quality detection device comprises a strength meter 1, the front side wall of the strength meter 1 is equipped with two mounting plates 2, the side wall of the mounting plate 2 is fixedly connected with a sleeve 3, the side wall of the sleeve 3 is fixedly connected with a first gear 4, the side wall of the mounting plate 2 away from the side is fixedly connected with a first motor 5, the output shaft of the first motor 5 is fixedly connected with a rotating shaft 6, the rotating shaft 6 passes through the sleeve 3 and is rotatably connected thereto, and the side wall of the first gear 4 is provided with two braided rope components;

[0030] The side walls of the mounting plate 2 are provided with a conductor assembly for guiding and conveying the woven yarn;

[0031] A support seat 28 is mounted on the side wall of the mounting plate 2 near the center of the strength meter 1. The lower support seat 28 is slidably connected to the mounting plate 2. A fixing component is disposed on the side wall of the support seat 28 for fixing both ends of the yarn.

[0032] like Figure 2 As shown, the braiding assembly includes a second gear 10 meshed on both sides of the first gear 4, at least two connecting plates 7 are installed on the side wall of the rotating shaft 6, and the side wall of the connecting plate 7 away from the rotating shaft 6 is fixedly connected to a ring 8, and a transmission shaft 9 is rotatably connected inside the ring 8. One end of the transmission shaft 9 is fixedly connected to the second gear 10, and the other end of the transmission shaft 9 is fixedly connected to a support plate 11, a wire drum 13 is installed inside the support plate 11, and a mounting assembly is provided on the side wall of the support plate 11;

[0033] The other end of the rotating shaft 6 is fixedly connected to a transverse plate 16 , and both ends of the transverse plate 16 are respectively fixedly connected to guide rings 17 .

[0034] When the yarn is knitted, the first gear 4 is in a fixed state, and the second gear 10 rotates around the first gear 4. Since the first gear 4 is meshed with the second gear 10, the bobbin 13 rotates while rotating, thereby facilitating the knitting of the yarn.

[0035] In addition, other connection methods such as screw connection, threaded connection, and clamping connection can be used between the connecting plate 7 and the rotating shaft 6. The user can increase or decrease the number according to the test requirements of the number of yarn strands.

[0036] like Figure 2 and Figure 5 As shown, the mounting assembly includes a movable plate 12 disposed inside a support plate 11, the support plate 11 is L-shaped, a bolt 15 is threadedly connected to the side wall of the movable plate 12, a plurality of screw holes 14 are provided on the side wall of the support plate 11, and the bolt 15 is threadedly connected to the screw hole 14. The side walls of the support plate 11 and the movable plate 12 are respectively provided with mounting holes corresponding to the wire drum 13, and the spacing between the movable plate 12 and the support plate 11 can be adjusted according to the model of the wire drum 13, so as to realize the installation of the wire drum 13.

[0037] like Figure 3 As shown, the wire assembly includes a second motor 18 fixedly connected to the side wall of the mounting plate 2, two round shafts 19 are arranged on the front side of the second motor 18, the output shaft of the second motor 18 is fixedly connected to one of the round shafts 19, and the other round shaft 19 is rotatably connected to the mounting plate 2, and the side walls of the two round shafts 19 are fixedly connected to third gears 21, and the third gears 21 on both sides are meshed with each other, and the side walls of the round shaft 19 are fixedly connected to guide wheels 20 located in front of the third gears 21, and one of the side walls of the round shaft 19 is drivingly connected to the heating assembly. The side walls of the guide wheels 20 are all provided with arc grooves 22.

[0038] Specifically, the woven yarn enters between the upper arc grooves 22, and the reverse rotation of the third gears 21 on both sides can squeeze and transport the yarn while providing downward traction. In order to further adapt to yarns of different strands, rubber pads, silicone pads or sponges can be provided on the side walls of the arc grooves 22.

[0039] like Figure 1 and Figure 4 As shown, the fixing assembly includes a screw 29 threadedly connected to the side wall of the support seat 28, one end of the screw 29 is fixedly connected to a rotating wheel, the other end of the screw 29 is rotatably connected to a switching block 30, the side wall of the switching block 30 is fixedly connected to an inclined rod 31, the side wall of the inclined rod 31 is fixedly connected to a positioning rod 32, the fixing assemblies on both sides are arranged in opposite directions, and a tension assembly is arranged on the lower fixing assembly.

[0040] Specifically, the two ends of the yarn can be wrapped and connected to the inclined rod 31 and the positioning rod 32, and knotting is used as a fixing method of this solution. Since the inclined rods 31 on both sides are inclined at relative angles, combined with the limitation of the positioning rod 32, when the yarn is subjected to force, it will not fall off, thereby effectively improving its stability.

[0041] like Figure 6 As shown, the side wall of the inclined rod 31 is provided with a thread near the end face, the side wall of the inclined rod 31 is threadedly connected with a nut 33, and the side wall of the inclined rod 31 is provided with a through hole 34. After the yarn is wound on the inclined rod 31, the end of the yarn is passed through the through hole 34, and the nut 33 is tightened to press and fix the yarn, which can be used as another fixing method of the present solution.

[0042] like Figure 3 As shown, the heating assembly includes a first connecting rod 23 fixedly connected to the side wall of the circular shaft 19, the side wall of the first connecting rod 23 is rotatably connected to the second connecting rod 24, the side wall of the second connecting rod 24 is rotatably connected to the telescopic plate 25, the side wall of the mounting plate 2 is fixedly connected to the limiting plate 26, the telescopic plate 25 passes through the limiting plate 26 and is movably connected thereto, and the side wall of the telescopic plate 25 is fixedly connected to a heating ring 27.

[0043] Among them, the flocs on the yarn surface will increase the friction between the yarn and the test instrument fixture and stretching components. When these flocs are present, the friction may be unevenly distributed on the yarn surface during the stretching process, causing the tension on the yarn to not be completely along the yarn axis, resulting in deviations in the strength data obtained from the test. Melting the flocs can make the yarn surface smoother, reduce the error caused by uneven friction, and make the test results more truly reflect the actual strength of the yarn.

[0044] like Figure 1 As shown, the tension assembly includes a fixing plate 35 fixedly connected to the left and right side walls of the lower support seat 28 , and two electric push rods 36 are fixedly connected to the side walls of the mounting plate 2 , and the output ends of the electric push rods 36 are fixedly connected to the fixing plate 35 .

[0045] Specifically, the tension component in this solution is only used as a driving structure or replacement structure. In practical applications, the power of the yarn strength tensile test mainly relies on the internal driving structure of the strength meter 1, which is an existing mature technology and will not be described in detail in this solution.

[0046] The working principle of the present invention is as follows: when a single or multiple strands of yarn need to be subjected to a strength test, a yarn of appropriate length is selected, and the heating ring 27 is started to emit heat, and one end of the yarn is passed through the arc groove 22 between the two upper guide wheels 20, and then passes through the heating ring 27 and the lower arc groove 22 in sequence. After the yarn passes through the heating ring 27, the heat generated by the heating ring 27 is used to melt the floccules on the surface of the yarn, so as to facilitate the subsequent observation of the yarn break position;

[0047] Then, the two ends of the yarn are respectively wound around the inclined rod 31 and the positioning rod 32, and the yarn ends are passed through the through hole 34 and tightened, and then the nut 33 is tightened to press the yarn to fix the yarn, and then the electric push rod 36 is started, and the electric push rod 36 drives the lower side fixing assembly to move downward, slowly tightening the yarn, and the strength test is completed after the yarn breaks;

[0048] When it is necessary to test the strength of the woven yarn, the bobbin 13 with the yarn is installed on the support plate 11, and one end of the yarn on the bobbin 13 is passed through the guide ring 17, the arc groove 22 and the heating ring 27 in sequence, and then the yarn is knotted, and then the first motor 5 and the second motor 18 are started, and the output shaft of the first motor 5 drives the connecting plate 7 to rotate through the rotating shaft 6, and the connecting plate 7 drives the transmission shaft 9 and the second gear 10 to rotate through the ring 8. Since the second gear 10 is meshed with the first gear 4, the bobbin 13 rotates around the rotating shaft 6 and rotates on its own at the same time, so that multiple strands of yarn are woven together;

[0049] The second motor 18 drives the third gear 21 to rotate, and the third gears 21 on both sides are meshed with each other to guide and transport the woven yarn downward. At this time, the heating ring 27 is started, and the heating ring 27 slightly melts the flocs on the yarn. After the yarn is woven to a suitable length, the two ends of the yarn are fixed by a fixing component, and then a strength test is performed.

[0050] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
