[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0077] The operation control of spinning machines is crucial to ensure production efficiency, product quality and long-term stable operation of the machines. An optimized control system can accurately adjust machine parameters such as line speed, tension and temperature to adapt to different production needs and improve the flexibility and response speed of the production line. Good operation control can also detect and solve faults and abnormalities in production in a timely manner, reduce downtime and improve continuous production capacity. At the same time, this also helps to save energy and reduce consumption, reduce production costs and enhance market competitiveness. Therefore, the operation control of spinning machines is the key to realizing automated and intelligent production in the textile industry.

[0078] Prior to the technology of the present invention, the prior art disclosed a weaving device for a warp knitted fabric, which is a two-layer structure, the upper structure is installed above the supporting structure, and the lower structure is located below the supporting structure; the upper structure includes a steel platform, on which are installed a number of yarn guide units, each of which guides a set number of yarn bundles, and each of which is provided with a tension adjusting device and a yarn guide plate, and after the tension of the yarn bundle is adjusted by the tension adjusting device, the yarn bundle enters the yarn guide plate for yarn separation; this structure can improve the uniformity of the warp tension distribution, but lacks an online adjustment method to achieve tension testing and uniform tension in the entire spinning process.

[0079] In an embodiment of the present invention, a method for testing and uniformly distributing the tension of multiple spinning lines is provided. The scheme coordinates each group of rollers to optimize the tension distribution when the vertical and horizontal distances between the supporting rollers of each crimping machine and the spinning machine head are the same but the vertical and horizontal distances between each production line and the spinning machine head are different.

[0080] According to a first aspect of an embodiment of the present invention, a method for testing the tension of multiple spinning threads and adjusting the tension distribution thereof is provided.

[0081] Figure 1 It is a flow chart of a method for tension testing and uniform distribution adjustment of multiple spinning lines according to an embodiment of the present invention.

[0082] In one or more embodiments, preferably, the method for testing the tension of multiple spinning lines and adjusting the uniform distribution thereof comprises:

[0083] S101, setting the structure of the spinning machine production line;

[0084] S102, setting the position of the spinning machine head of the spinning machine production line;

[0085] S103, monitoring tension by a cantilever tension detector;

[0086] S104, setting the roller group height;

[0087] S105, changing the tension of the tow during normal travel by adjusting the height difference between the roller group pairs and adjusting the distance and height difference between the two rollers in the group;

[0088] S106, online optimization of multi-tow angle differences.

[0089] In the embodiments of the present invention, the vertical and horizontal distances between the clamping rollers of each crimping machine and the head of the spinning machine are the same, but the vertical and horizontal distances between each production line and the head of the spinning machine are different. This causes inconsistent tow travel of each production line, and since the crimping machines are arranged horizontally in two layers, the angles of the tows of each production line after coming out of the head of the spinning machine are very different, resulting in uneven tension distribution of multiple tows. It is necessary to optimize the tension distribution through the cooperation of each group of rollers according to the quality of the production line.

[0090] Figure 2 It is a flow chart of the structure of setting up a spinning machine production line in a method for tension testing and uniform distribution adjustment of multiple spinning lines in one embodiment of the present invention.

[0091] like Figure 2 As shown, in one or more embodiments, preferably, the structure of setting the spinning machine production line specifically includes:

[0092] S201, setting a group of carbon steel rollers for conveying head tows at the head position of the spinning machine production line;

[0093] S202, a group of carbon steel rollers for transmitting the middle tow are arranged at the dovetail groove position of the spinning machine head;

[0094] S203, a group of carbon steel rollers for transmitting the tail tow are arranged at the gantry position of the crimping room;

[0095] S204, setting the tow to be conveyed into the crimping machine clamping conveying roller;

[0096] S205, the crimping machine clamps the transmission rollers to clamp the wire bundle and the motor drives the rollers to rotate the wire bundle forward;

[0097] S206. Different traction forces are provided to the yarn bundle by adjusting the clamping pressure and rotation speed of the crimping machine.

[0098] In an embodiment of the present invention, a group of carbon steel rollers for transmitting the head tow is arranged at the head position of the spinning machine production line, a group of carbon steel rollers for transmitting the middle tow is arranged at the dovetail groove position of the spinning machine head, and a group of carbon steel rollers for transmitting the tail tow is arranged at the gantry position of the crimping machine room, and finally the tow is transmitted to the crimping machine clamping and transmitting roller pair. The crimping machine clamping and transmitting roller pair clamps the tow and drives the roller pair to rotate by the motor to rotate the tow forward, and provides different traction forces for the tow by adjusting the clamping pressure and rotation speed of the crimping machine. Among them, the clamping pressure and rotation speed of the crimping machine are positively correlated with the traction force.

[0099] Figure 3 It is a flow chart of setting the position of the spinning machine head of a spinning machine production line in a method for tension testing and uniform distribution adjustment of multiple spinning lines according to an embodiment of the present invention.

[0100] like Figure 3 As shown, in one or more embodiments, preferably, the position of the spinning machine head of the spinning machine production line is set, specifically including:

[0101] S301, setting the vertical and horizontal distances between the clamping rollers of each crimping machine and the spinning machine head to be the same;

[0102] S302, setting the vertical and horizontal distances from each production line to the spinning machine head to be different;

[0103] S303, the crimping machine is arranged in two layers;

[0104] S304. 18 pairs of rollers are provided, wherein the first six pairs of carbon steel rollers are used to convey the head wire bundle, the middle six pairs of carbon steel rollers are used to convey the middle wire bundle, and the tail six pairs of carbon steel rollers are used to convey the tail wire bundle.

[0105] In an embodiment of the present invention, the vertical and horizontal distances between the clamping rollers of each crimping machine and the head of the spinning machine are set to be the same, and the vertical and horizontal distances from each production line to the head of the spinning machine are set to be different. Through the above settings, the yarn travel of each production line is inconsistent; the crimping machines are arranged in two layers, and there are large angle differences between the yarn bundles of each production line after coming out of the head of the spinning machine, resulting in uneven tension distribution of multiple yarn bundles; among them, the first six pairs of carbon steel rollers are used to convey the head yarn bundles, the middle six pairs of carbon steel rollers are used to convey the middle yarn bundles, and the tail six pairs are used to convey the tail yarn bundles.

[0106] Figure 4 It is a flow chart of monitoring tension by a cantilever tension detector in a method for tension testing and uniform distribution adjustment of multiple spinning lines according to one embodiment of the present invention.

[0107] like Figure 4 As shown, in one or more embodiments, preferably, the monitoring of tension by a cantilever tension detector specifically includes:

[0108] S401, cantilever tension detector is used to support cantilever idler rollers on single wall panel equipment;

[0109] S402, the cantilever tension detector performs online detection of the tow tension through a cantilever idler roller.

[0110] In an embodiment of the present invention, after completing the matching distribution of the above-mentioned groups of carbon steel rollers, it is necessary to perform online detection of the tension of the yarn bundle. The selected cantilever tension detector is designed to support the cantilever idler roller on the single wall panel equipment, and the cantilever idler roller can accurately measure the tension of the yarn bundle.

[0111] Figure 5It is a flow chart of setting the height of a roller group in a method for tension testing and uniform distribution adjustment of multiple spinning lines according to an embodiment of the present invention.

[0112] like Figure 5 As shown, in one or more embodiments, preferably, setting the roller group height specifically includes:

[0113] S501, setting the vertical and horizontal distances between the clamping rollers of each crimping machine and the spinning machine head to be the same;

[0114] S502, setting different vertical and horizontal distances from each production line to the spinning machine head.

[0115] In the embodiments of the present invention, the vertical and horizontal distances between the clamping rollers of each crimping machine and the head of the spinning machine are the same, but the vertical and horizontal distances between each production line and the head of the spinning machine are different, which causes inconsistent thread travel of each production line. Moreover, since the crimping machines are arranged horizontally in two layers, the angles of the thread bundles of each production line after coming out of the head of the spinning machine are greatly different, resulting in uneven tension distribution of multiple thread bundles. It is necessary to optimize the tension distribution according to the quality of the production line and the cooperation of each group of rollers.

[0116] Figure 6 It is a flow chart of a method for testing and uniformly distributing the tension of a multi-spinning line in one embodiment of the present invention, which changes the tension of a yarn bundle during normal travel by adjusting the height difference between roller pairs and the distance and height difference between two rollers in the group.

[0117] like Figure 6 As shown, in one or more embodiments, preferably, the height difference adjustment between the roller group pairs and the distance adjustment and height difference adjustment between the two rollers in the group are used to change the tension of the tow during normal travel, which specifically includes:

[0118] S601, determining the tension of each tow, and comparing the first calculation formula, the second calculation formula and the preset tension value;

[0119] S602: When the first calculation formula is not satisfied, it is considered that the tension is too large;

[0120] S603, when the second calculation formula is not satisfied, it is considered that the tension is too small;

[0121] S604, when the tension is too large, while the height difference between the rollers remains unchanged, reducing the tension of the tow by increasing the horizontal distance between the rollers at a preset spacing;

[0122] S605, when the tension is too small and the horizontal distance between the rollers remains unchanged, increasing the tension of the tow by increasing the height difference between the rollers at a preset spacing;

[0123] The first calculation formula is:

[0124] S>Y1

[0125] Wherein, S is the tension of the tow, and Y1 is the preset first tension comparison margin;

[0126] The second calculation formula is:

[0127] S <Y2

[0128] Wherein, Y2 is a preset second tension comparison margin.

[0129] In an embodiment of the present invention, in the running path of the yarn bundle, the tension of the yarn bundle during normal travel is changed by adjusting the height difference between the roller group pairs and the distance and height difference between the two rollers in the group; if the tension is too high during the running of the yarn bundle, it may cause a high flying flower value in the yarn bundle quality index (the lower the flying flower value, the better), and the total denier of the yarn bundle deviates from the center value, and in severe cases, the yarn bundle may be broken, causing production interruption; if the tension is too low during the running of the yarn bundle, the cohesion of the yarns in the yarn bundle is insufficient, which may cause the yarn bundle to diverge and the total denier of the yarn bundle to deviate from the center value, and in severe cases, the yarn bundle sags and detaches from the roller surface, causing production interruption; when the height difference between the rollers remains unchanged, the yarn bundle tension can be reduced by increasing the horizontal distance between the rollers; when the horizontal distance between the rollers remains unchanged, the yarn bundle tension can be increased by increasing the height difference between the rollers.

[0131] like Figure 7 As shown, in one or more embodiments, preferably, the online optimization of the multi-tow angle difference specifically includes:

[0132] S701, determining the angle difference between each current tow in real time;

[0133] S702, sorting the angle differences, and extracting the two tows with the largest angle differences as the maximum angle deviations;

[0134] S703, determining whether the maximum angle deviation satisfies a third calculation formula, and if so, when the height difference and horizontal distance between the two tows with the largest angle difference are consistent, the tow angle is changed by adjusting the rollers themselves up and down or left and right until the third calculation formula is no longer satisfied;

[0135] The third calculation formula is:

[0136] P>Y3

[0137] Among them, P is the maximum angle deviation, and Y3 is the preset angle deviation comparison margin.

[0138] In an embodiment of the present invention, when the height difference and horizontal distance between the rollers are consistent, the tow angle can be changed by adjusting the rollers themselves up and down or left and right, and the angle difference of multiple tows can be optimized to ensure that the angle of the tow entering the crimping machine is homogeneous.

[0139] According to a second aspect of an embodiment of the present invention, a system for testing and uniformly distributing tension of multiple spinning lines is provided.
