Tension control device of yarn power transmitter {IMPROVED TENSION CONTROL APPARATUS PAY-OFF MACHINE}

The present invention relates to the improvement of a tension control device of a kind of a yarn off power machine, and is easy to design and install. In addition, when winding the knitting yarn (line), the yarn is not easily cut and the yarn deformation does not appear easily, thereby achieving a balanced tension effect. Therefore, the woven fabric has balanced tension, balanced resistance and density, so that high-quality product effects can be obtained, which is ideal for real-life applications. Tension of a yarn off-machine that has never been seen before It is an improvement of the control device.

According to the execution method of industrial goods or household knitting products made of metal thread (wire) or non-metal wire (thread), various kinds of thread wound on the winder are first wound up by a pay-off machine. It was pulled into the Take Up Machine and each thread was running smoothly. Among them, the tension control device is installed in the Pay Off Machine, and each thread (line) is running smoothly through the tension control device. Conventionally known methods of installing and implementing a tension control device for a Pay Off Machine are shown in FIGS. 1 and 2. The main structure of the lever 10 is that the axis A is moved up and down by using the axis A moves, the roller 11 is installed on one side of this to contact the brake shaft 12, the other part is elastic There is a flow pulley 14 which is pulled down under the influence of the component 13. The periphery of the roller 11 is in contact with the accentric 15 while applying pressure to each other, and the tension shaft 16 is provided on the accentric 15. The other end of the tension shaft 16 is provided with a wire ring 17. The brake belt 18 is provided in the other part of this brake shaft 12, and the brake belt 18 is installed around the brake drum 19. As shown in FIG. When the elastic part 13 pulls down one part of the lever 10, the roller 11 installed on the other part of the lever 10 rises up to move in contact with the accent 15 and the accent 15 The tension shaft 16 installed in the upper portion moves up. At the same time, the brake shaft 12, which is installed at the same portion as the roller 11 and the lever 10, is also pulled up together so that the brake belt 18 exerts a relatively large contact pressure on the brake drum 19. The brake drum 19 is installed on the winder spindle shaft 20, and a driven gear 21 is installed at one portion of the winder spindle shaft 20 and engaged with the main gear 22 to engage the sensor motor. Move (23). The other part is provided with a winder 24 for supplying the knitting room (line) B. Knitting thread (line) B wound on the winder 24 passes through the lead ring 14 on the lever 10 and reaches the lead ring 17 on the tension shaft 16, and the winder It is dubbed (not provided).

When Take Up performs the work of winding the thread, the sensor motor 23 and the winder 20 of the Pay Off Machine move to move the winder 24 installed on the winder spindle shaft. ) Will also move together, releasing knitted yarn (line) B. In addition, when Take Up applies instantaneous pulling force to knitting room B, the knitting room B makes a large instantaneous pulling force to the wire wheel 17 on the tension shaft 16. As a result, the tension shaft 16 is moved downward to cushion the knitting chamber (line) B, thereby achieving the purpose of preventing the cutting of the line instantaneously. In other words, when the tension shaft 16 is moved downward, the accent 15 is also moved together, and the roller 11 which is in contact with the accent is pressurized downward so that the brake shaft 12 is installed at the same part. In addition, the action of applying pressure together, the brake belt 18 installed in the brake shaft 12 is in contact with the brake drum 19 in a loose form is set so that the sensor motor 23 moves quickly. In addition, the winder 24 also moves quickly together to send a knitting room (line) B so that the tension shaft 16 moves upward and returns. After the tension shaft 16 is moved up and restored to its original position, the brake shaft 12 is also pulled up so that the brake belt 18 applies a set contact pressure to the brake drum 19 so that the sensor motor 23 speeds up. The deceleration rate causes the feed rate of the pay-off to be the same as the winding speed of the take-up. That is, the image of the tension shaft 16 above. Knitting thread (line) B through the lower motion is wound in the take-up (Take Up) in a tension state to achieve the effect of reducing the phenomenon that the thread is cut. However, after a long time of use, the companies still found the following shortcomings.

1.Tension shaft 16 is limited to about 90 degrees of movement up and down, so when the tension of the take-up (Take Up) momentarily pulling the knitting thread (line) B is very large, the tension shaft (16) Since it is restricted to move downward momentarily, knitting yarn (line) B is often cut or the yarn is deformed.

2. The knitting yarn (line) B described in 1 above is often cut and the yarn (line) is deformed, and the worker often has to reconnect the yarn (line) and the density imbalance of the woven knitted fabric. Resistance imbalances and even tension imbalances lead to quality defects.

3. Since the brake belt 18 exerts contact pressure on the brake drum 19 and the sensor motor 23 slows down the speed, the sensor motor easily generates heat, which affects the service life of the device. This came to be.

The present invention aims to provide an improvement of the tension control device of a yarn off-machine.

Among them, a pulley part is installed at the back of the winder spindle shaft of the pay off machine to send the knitting room (line) to the take-up machine. The pulley's lifting and lowering movements provide tension and cushioning of the knitting yarn (line) spinning above.
