Abstract
Description
Technical Field
[0001] The utility model relates to the field of frame stranding machines, in particular to a tension control device for a pay-off drum of a frame stranding machine. Background Art
[0002] The frame stranding machine is a device for twisting multiple wires into bundles, and is widely used in the twisting and forming process of the core conductor of the cable. Multiple pay-off drums are placed on the frame stranding machine, and then the frame stranding machine twists the wires to be twisted (such as copper wires) released from the multiple pay-off drums into bundles. In order to ensure the twisting quality of the wires to be twisted after being twisted, the pay-off tension of the pay-off drum needs to be kept consistent to avoid the tightness deviation of the wires to be twisted when they are twisted into bundles, which is not conducive to the high-quality forming of the core conductor. Different pay-off drums will have different pay-off tensions due to different wear conditions during production and use; and the tension of the same pay-off drum will change at any time due to the change in the number of wires to be twisted on the pay-off drum. For example, as the pay-off drum continuously pays off the wire, the pay-off tension will become larger and larger because the pay-off diameter of the pay-off drum becomes smaller, that is, the pay-off tension of the full pay-off drum is the smallest; at the same time, the pay-off tension required for the wires to be twisted of different diameters will also be different, which makes it difficult for the pay-off drum to use a unified pay-off tension to meet the use requirements.
[0003] Traditional pay-off reels mainly set the required pay-off tension for different pay-off reels regularly based on the operator's operating experience, and gradually reduce the tension according to the production progress, so that multiple pay-off reels are under good pay-off tension at different pay-off stages, and the operator is required to pay attention to the pay-off stage of the pay-off reel at all times. However, this method requires high experience and high concentration of work energy from the operator. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a tension control device for a pay-off drum of a frame stranding machine, which reduces the operating experience requirements of the frame stranding machine on the operator and enables each pay-off drum to have a self-regulating pay-off tension function.
[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a tension control device for a wire pay-off drum of a frame stranding machine, comprising a frame stranding machine, wherein a plurality of wire pay-off drums are arranged on the frame stranding machine, and wires to be twisted are wound on the wire pay-off drums, and a pneumatic ejector for adjusting the wire pay-off tension of the wire pay-off drum is arranged on the axis of each of the wire pay-off drums, and a pressure measuring assembly for testing the wire pay-off tension is arranged downstream of the wire pay-off drum, and a control system is arranged between the pressure measuring assembly and the pneumatic ejector, and the control system adjusts the pneumatic ejector to control the wire pay-off tension of the wire pay-off drum according to the pressure data of the pressure measuring assembly.
[0006] Compared with the prior art, the utility model has the following advantages: when the pay-off drum releases the wire to be twisted, the wire to be twisted will pass through the pressure measuring assembly, and the pressure measuring assembly can be used to measure the pressure of the wire to be twisted in the pressure measuring assembly in real time, so as to judge the wire-paying tension of the pay-off drum at this time, and then the pneumatic ejector is controlled to control the wire-paying tension of the pay-off drum according to the wire-paying tension through the control system, so as to ensure that the pay-off drum is always in a good wire-paying tension range, whether it is the tension difference caused by wear, the tension change caused by the pay-off drum itself during the wire-paying process, or the tension difference caused by wires to be twisted of different specifications, it is not necessary to rely on experience for detailed judgment, the pay-off drum only needs to self-adjust through the pressure measuring assembly and the control system to meet the wire-paying tension, thereby greatly reducing the operator's experience requirements for the frame stranding machine; at the same time, the wire to be twisted released by each pay-off drum passes through a pressure measuring assembly design, so as to ensure the self-adjustment independence of each pay-off drum, without being interfered by other pay-off drums, and to ensure the wire-paying quality of each pay-off drum.
[0007] As an improvement of the utility model, the pressure measuring assembly includes three guide wheels, and the three guide wheels include a first fixed pulley, a pressure measuring pulley and a second fixed pulley. The pressure measuring pulley is arranged between the first fixed pulley and the second fixed pulley. The wire to be twisted is released from the pay-off drum and passes through the first fixed pulley, the pressure measuring pulley and the second fixed pulley in a wave shape in sequence. A pressure measuring instrument is provided at one end of the pressure measuring pulley away from the pressure measuring pulley and connected to the wire to be twisted. The pressure measuring instrument is electrically connected to the control system. Through the improvement, the pressure measuring operation of the pressure measuring assembly is realized. At the same time, the constraint of the first fixed pulley and the second fixed pulley on the wire to be twisted can ensure the accuracy of the pressure measurement of the wire to be twisted by the pressure measuring pulley and the pressure measuring instrument.
[0008] As an improvement of the present invention, the diameter of the first fixed pulley for the wire to be twisted to be wound around is equal to the diameter of the second fixed pulley for the wire to be twisted to be wound around, and the rotation center of the first fixed pulley and the rotation center of the second fixed pulley are on the same horizontal plane, the pressure measuring pulley is arranged on the perpendicular midline of the first fixed pulley and the second fixed pulley, and the pressure measuring instrument is also arranged on the perpendicular midline of the first fixed pulley and the second fixed pulley. Through the improvement, it is ensured that the force direction between the wire to be twisted and the pressure measuring pulley is on the perpendicular midline of the first fixed pulley and the second fixed pulley, thereby ensuring the pressure measurement accuracy of the pressure measuring instrument, and avoiding measurement deviation caused by the inclination of the force direction between the wire to be twisted and the pressure measuring pulley and the perpendicular midline of the first fixed pulley and the second fixed pulley.
[0009] As an improvement of the utility model, the pressure measuring assembly is arranged on the center dividing plane in the length direction of the wire pay-off drum, and adjusting disks for adjusting the release direction of the wire to be twisted are provided on both sides of the first fixed pulley. The opposite sides of the two adjusting disks are inclined, and the distance between the two adjusting disks decreases from the edge of the adjusting disk toward the center of the adjusting disk. Through the improvement, the consistency of the direction of the wire to be twisted after entering the pressure measuring assembly is ensured, and the design of the adjusting disk can ensure the stability of the wire to be twisted entering the pressure measuring assembly, thereby guiding the wire to be twisted into the pressure measuring assembly.
[0010] As an improvement of the utility model, the outlet end of the frame twisting machine is provided with an outlet winch, and the outlet winch is provided with a plurality of outlet holes corresponding to each pay-off drum. On the outlet winch with the plurality of outlet holes evenly distributed in an array, the outlet end of the pressure measuring assembly connected to any one of the pay-off drums and the outlet hole corresponding to the pay-off drum are arranged horizontally. Through the improvement, the independence of the pay-off of each pay-off drum is ensured, and the interference of the wires to be twisted released by different pay-off drums during the transportation process is avoided, thereby ensuring the twisting quality of the frame twisting.
