[0002] During the unwinding process of the bobbin of the automatic winding machine, the yarn forms balloons of different numbers of knots and diameters, and the unwinding tension is constantly changing and fluctuating. Therefore, the tension adding device of the automatic winding machine will adjust the tension added to the yarn in real time according to the tension change monitored by the tension sensor in real time. This tension closed-loop adjustment system can effectively feedback and make corresponding adjustments for continuous and obvious tension changes, but cannot effectively respond to sudden or small tension fluctuations. Therefore, the tension adding device often has a buffering structure, which can ensure the suppression of small tension fluctuations of the yarn.

Detailed implementation mode
[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] See Figures 1-5 , an embodiment of an automatic winder for automatically adjusting and controlling tension according to the present utility model, includes a single spindle of the winder. The single spindle of the winder includes a bobbin tube, a bobbin arm, a grooved drum, a grooved drum drive mechanism, a tube changing drive mechanism, a yarn knotting mechanism, a tension control mechanism and a single spindle controller. The tension control mechanism includes an upper yarn guiding plate 15, a lower yarn guiding plate 14 and a yarn tension control device. The grooved drum drive mechanism, the tube changing drive mechanism, the yarn knotting mechanism and the tension control mechanism are all connected to the single spindle controller. An upper yarn guiding slit 15.1 is provided on the upper yarn guiding plate 15, a lower yarn guiding slit 14.1 is provided on the lower yarn guiding plate 14, and a fixed ceramic 13 is provided on each of the upper yarn guiding plate 15 and the lower yarn guiding plate 14. The above-mentioned yarn tension control device includes a fixed plate 2 and at least one set of yarn tension adjustment units provided on the fixed plate 2. The above-mentioned yarn tension adjustment units are located on the yarn path between the upper yarn guiding plate 15 and the lower yarn guiding plate 14. The yarn tension adjustment unit includes an actuating rotary element 1, a rotating shaft 3, a turntable 5 and a flexible buffer yarn tension adjustment component provided on the turntable 5. The actuating rotary element 1 and the rotating shaft 3 are respectively provided on both sides of the fixed plate 2. The turntable 5 is provided at one end of the rotating shaft 3, and the other end of the rotating shaft 3 is connected to the actuating rotary element 1. The flexible buffer yarn tension adjustment component forms a flexible bent yarn path. The flexible buffer yarn tension adjustment component cooperates with the fixed ceramic 13 through the movable ceramic 7 therein to clamp the passing yarn 12, and controls the actuating rotary element 1 to drive the rotating shaft 3 and the turntable 5 to rotate through the single spindle controller, so as to automatically adjust the tension of the yarn 12 passing through the flexible bent yarn path.
[0023] Since the actuating rotary element 1 will act quickly and sensitively with a large torque and acceleration after receiving the tension adjustment feedback signal from the single-spindle controller and rotate to the corresponding tension application angle, at the start and end moments of rotation, due to an obvious sudden change in speed, a large inertial force will be generated, which will cause impact. Therefore, a flexible buffer force is required for buffering adjustment.
[0024] The first specific implementation: The above flexible buffer yarn tension adjustment assembly includes two sets of yarn clamping assemblies composed of a movable ceramic 7, a pressure rod 6, a movable ceramic swing rod 4, a swing rotating shaft 8, a fixed magnet 10 and a movable magnet 4.1. One end of the swing rotating shaft 8 is connected to the turntable 5, and the other end of the swing rotating shaft 8 is rotatably connected to the middle of the movable ceramic swing rod 4. A pressure rod 6 is arranged at the end of the movable ceramic swing rod 4 extending out of the turntable 5, and a movable ceramic 7 is arranged on the pressure rod 6. A movable magnet 4.1 is arranged on the side of the movable ceramic swing rod 4 close to the center of the turntable 5, and the fixed magnet 10 is fixedly installed on the turntable 5 at a position close to the movable magnet 4.1. The repulsive force between the movable magnet 4.1 and the fixed magnet 10 is inversely proportional to the square of the distance between the two, serving as the flexible buffer force.
[0025] During specific installation, the fixed magnet 10 and the movable magnet 4.1 have the same polarity facing outwards, that is, the mutually approaching surfaces of the fixed magnet 10 and the movable magnet 4.1 are of the same polarity. In this way, the same polarity repels each other, resulting in that one end of the movable ceramic swing rod 4 always presses on the soft pad 11.1 arranged on the side of the limit block 11 in the initial state. After the turntable 5 rotates and presses the yarn 12, the distance between the fixed magnet 10 and the movable magnet 4.1 becomes smaller, the repulsive force increases, and the force pressing the yarn 12 also becomes larger, and the damping can buffer and absorb the tension fluctuation of the yarn 12. During use, the fixed magnet 10 and the movable magnet 4.1 can be maintenance-free and do not need to be cleaned.
[0026] Furthermore, a limit block 11 is arranged on the turntable 5 close to the fixed magnet 1 to limit the maximum rotation angle of the movable ceramic swing rod 4, and one end of the movable ceramic swing rod 4 is located between the limit block 11 and the corresponding fixed magnet 10 or fixed solenoid. Preferably, a soft pad 11.1 is arranged on the side of the limit block 11 facing the movable ceramic swing rod 4, which can buffer the collision between the limit block 11 and the movable ceramic swing rod 4.
[0027] The second specific implementation: The above-mentioned flexible buffer yarn tension adjustment component includes two sets of yarn clamping components composed of a movable ceramic 7, a pressure rod 6, a movable ceramic swing rod 4, a swing rotating shaft 8 and an elastic element. One end of the swing rotating shaft 8 is connected to the turntable 5, and the other end of the swing rotating shaft 8 is rotatably connected to the middle of the movable ceramic swing rod 4. A pressure rod 6 is arranged at the end of the movable ceramic swing rod 4 extending out of the turntable 5, and a movable ceramic 7 is arranged on the pressure rod 6. The elastic element and the limit block 11 are arranged at intervals at a position on the turntable 5 close to the other end of the movable ceramic swing rod 4. One end of the elastic element is fixedly connected to the turntable 5, and the other end of the elastic element is connected to one end of the movable ceramic swing rod 4. The elastic element makes the movable ceramic swing rod 4 elastically lean against the limit block 11. When pressing the yarn 12, the elastic element will buffer and absorb shock while increasing the clamping force.
[0028] Preferably, the above-mentioned elastic element is a compression spring or a tension spring, a torsion spring or a shock-absorbing rubber. When a compression spring is adopted, the compression spring and the limit block 11 are respectively arranged on the turntable 5 on both sides of one end of the movable ceramic swing rod 4.
[0029] Furthermore, the above-mentioned movable ceramic 7 is a cylinder, and a guide yarn annular groove 9 is arranged on the side wall in the middle of the movable ceramic 7 for guiding the yarn 12 into it to ensure the stability of the yarn path. The guide yarn annular groove 9 is used to clamp the yarn 12 to prevent the yarn 12 from jumping back and forth. However, when this cylindrical surface presses against the fixed ceramic 13 surface, it is not limited to a line contact. Pressing the yarn 12 like this is not good, and it can be understood as having a surface fit, which is easier to control the tension of the yarn 12.
[0030] Furthermore, as Figure 5 shown, there are two sets of the above-mentioned yarn tension adjustment units, which are arranged vertically on the yarn path between the upper yarn guide plate 15 and the lower yarn guide plate 14.
[0031] The above-mentioned actuating rotary element 1 of the present invention adopts a stepping motor or a rotary driving component with a similar function.
[0032] A control method for the yarn tension control device of the above-mentioned winding machine of the present invention includes the following steps:
[0033] Step 1: Lead out the yarn 12 from the cheese, pass it through the lower yarn guide slit 14.1 on the lower yarn guide plate 14, the flexible bent yarn path formed by the flexible buffer yarn tension adjustment component, and the upper yarn guide slit 15.1 of the upper yarn guide plate 15, and then connect it to the bobbin tube. At the initial position of the flexible bent yarn path, the yarn 12 passing through the flexible bent yarn path is in a straight line.
[0034] Step 2: When the unwinding of yarn 12 starts, the yarn 12 is unwound from the cheese and wound onto the bobbin tube. The single-spindle controller controls the actuating rotary element 1 to drive the rotary shaft 3 and the turntable 5 to rotate, driving the two movable ceramic swing rods 4 to rotate, causing the yarn 12 passing through the flexible bent yarn path to be in a zigzag shape, and clamping the yarn 12 to generate a flexible buffer tension on the yarn 12.
[0035] Step 3: When there is a tension fluctuation generated when the yarn 12 runs at high speed or a rigid impact of the acting force when the actuating rotary element 1 rotates to apply tension, the single-spindle controller controls the actuating rotary element 1 to drive the rotary shaft 3 and the turntable 5 to increase or decrease the rotation angle, automatically adjusting the tension of the yarn 12 passing through the flexible bent yarn path.
[0036] Further, in the above Step 1, when the yarn 12 passes through the flexible bent yarn path, it passes between the two fixed magnets 10 or fixed solenoids, and at the same time passes between the two movable ceramic swing rods 4 and passes through the center of the turntable 5.
[0037] In the above Step 2, the repulsive force generated between the fixed magnet 10 and the movable magnet 4.1 causes the movable ceramic swing rod 4 to swing around the swing shaft 8, generating a flexible buffer tension on the yarn 12.
[0038] In the above Step 3, the larger the rotation angle of the actuating rotary element 1 driving the rotary shaft 3 and the turntable 5, the greater the pressure on the yarn 12. During the process of clamping the yarn 12, when the tension fluctuation and yarn jitter of the yarn 12 are caused by the change of the unwinding tension, the two sets of yarn clamping components absorb the excessive change of the tension of the yarn 12 through different flexible change amounts, thereby balancing the tension.
[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
