Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0077] Operational control of spinning machines is crucial for ensuring production efficiency, product quality, and long-term stable operation. An optimized control system allows precise adjustment of machine parameters such as line speed, tension, and temperature to adapt to varying production needs, improving production line flexibility and responsiveness. Good operational control also enables timely detection and resolution of production failures and anomalies, minimizing downtime and improving continuous production capacity. This also contributes to energy conservation and consumption reduction, lowering production costs, and enhancing market competitiveness. Therefore, operational control of spinning machines is key to achieving 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 warp knitted fabrics, which is a two-layer structure, with the upper structure installed above the supporting structure and the lower structure located below the supporting structure; the upper structure includes a steel platform, on which are installed several yarn guide units, each of which guides a set number of yarn bundles, and each yarn guide unit is provided with a tension adjustment device and a yarn guide plate, after the yarn bundle is tension-adjusted by the tension adjustment device, it 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 throughout the spinning process.

[0079] In one embodiment of the present invention, a method for testing and uniformly distributing tension on multiple spinning lines is provided. This solution optimizes tension distribution by coordinating rollers in different groups when the vertical and horizontal distances between the crimping rollers and the spinning head are the same, but the vertical and horizontal distances between the production lines and the spinning head are different.

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

[0081] Figure 1 The present invention is a flowchart of a method for testing and uniformly distributing the tension of multiple spinning lines according to an embodiment of the present invention.

[0082] In one or more embodiments, preferably, the method for testing and uniformly distributing the tension of multiple spinning lines includes:

[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;

[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 pairs and the distance and height difference between the two rollers in the group;

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

[0089] In the embodiment of the present application, the vertical and horizontal distance from each crimping machine clamping roller to the spinning machine head is the same, but the vertical and horizontal distance from each production line to the spinning machine head is different, which causes the inconsistent travel of the tows of each production line, and because the crimping machine is horizontally arranged in two layers, the angle difference of the tows of each production line after coming out of the spinning machine head is large, which causes uneven distribution of the multi-tow tension, and the tension distribution optimization needs to be realized through the cooperation of each group of rollers according to the quality of the production line.

[0090] Figure 2 is a flow chart of setting the structure of the spinning machine production line in a multi-spun yarn line tension test and uniform distribution adjustment method according to an embodiment of the present application.

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

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

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

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

[0095] S204, the tows are conveyed into the crimping machine clamping conveying roller;

[0096] S205, the crimping machine clamping conveying roller rotates the tows forward by clamping the tows and driving the roller by the motor;

[0097] S206, different pulling forces are provided for the tows by adjusting the clamping pressure and rotating speed of the crimping machine.

[0098] In the embodiment of the present application, a group of carbon steel rollers for conveying the head tows are arranged at the head position of the spinning machine production line, a group of carbon steel rollers for conveying the middle tows are arranged at the dovetail groove position of the spinning machine head, a group of carbon steel rollers for conveying the tail tows are arranged at the gantry position of the crimping machine room, and finally the tows are conveyed into the crimping machine clamping conveying roller. The crimping machine clamping conveying roller rotates the tows forward by clamping the tows and driving the roller by the motor, and different pulling forces are provided for the tows by adjusting the clamping pressure and rotating speed of the crimping machine. The clamping pressure and rotating speed of the crimping machine are positively correlated with the pulling force.

[0099] Figure 3 is a flow chart of setting the position of the spinning machine head of the spinning machine production line in a multi-spun yarn line tension test and uniform distribution adjustment method according to an embodiment of the present application.

[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 tow, the middle six pairs of carbon steel rollers are used to convey the middle tow, and the tail six pairs of carbon steel rollers are used to convey the tail tow.

[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 between each production line and the head of the spinning machine are set to be different. Through the above settings, the yarn bundle strokes of each production line are 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 The present invention is a flowchart of a method for tension testing and uniform distribution adjustment of multiple spinning lines using a cantilever tension detector according to an 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 the 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 5This 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. Set the vertical and horizontal distances from each production line to the spinning machine head to be different.

[0115] In an embodiment of the present invention, the vertical and horizontal distances between the clamping rollers of each winding 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, which causes inconsistent tow strokes of each production line. Moreover, since the winding machines are arranged horizontally in two layers, the angles of the tows of each production line after coming out of the spinning machine head are very different, resulting in uneven tension distribution of multiple tows. It is necessary to optimize the tension distribution by cooperating with each group of rollers according to the quality of the production line.

[0116] Figure 6 This 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 adjusting 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 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, specifically including:

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

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

[0120] S603: If the second calculation formula is not satisfied, it is considered that the tension is too low;

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

[0122] S605, when the tension is too low and the horizontal distance between the rollers remains unchanged, increasing the tow tension 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 filament, Y1 is a preset first tension contrast margin;

[0126] The second calculation formula is:

[0127] S<Y2

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

[0129] In the embodiment of the application, in the running path of the filament, the tension of the filament in the normal running process is changed by adjusting the height difference between the roller groups and adjusting the distance and height difference of the two rollers in the group; if the tension of the filament is too high in the running process, the flying value in the quality index of the filament may be high (the lower the flying value is, the better), the total denier of the filament deviates from the center value, and the filament may be broken in severe cases, causing production interruption; if the tension of the filament is too low in the running process, the cohesion of each filament in the filament is insufficient, which may cause the filament to diverge and the total denier of the filament to deviate from the center value, and in severe cases, the filament may sag and deviate from the roller surface, causing production interruption; when the height difference between the rollers remains unchanged, the horizontal distance between the rollers can be increased to reduce the tension of the filament; when the horizontal distance between the rollers remains unchanged, the height difference between the rollers can be increased to increase the tension of the filament.

[0130] Figure 7 is a flow chart of online optimization of multi-filament angle difference in a multi-filament tension testing and uniform distribution adjusting method according to an embodiment of the application.

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

[0132] S701, judging the angle difference between each filament in real time;

[0133] S702, sorting the angle difference, extracting the two filaments with the largest angle difference as the maximum angle deviation;

[0134] S703, judging whether the maximum angle deviation satisfies a third calculation formula, if yes, when the height difference and the horizontal distance between the rollers of the two filaments with the largest angle difference are consistent, adjusting the up and down or left and right of the rollers to change the filament angle until the third calculation formula is not satisfied;

[0135] The third calculation formula is:

[0136] P>Y3

[0137] Wherein, 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 uniform.

[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.
