Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of transformer production, and particularly relates to a constant tension guiding device of a vertical winding machine for transformer production. BACKGROUND
[0002] The vertical winding machine is a key equipment for manufacturing large transformer coils in the electrical engineering field, and its structure comprises core components such as a multi-station bearing table, a division control device and a winding assembly. The equipment realizes accurate control through the combination of mechanical speed regulation and frequency conversion speed regulation system, and adopts tension control technology to improve the tightness of the coil. When the transformer is wound by the winding machine, the wound coil needs to be tensioned so as to be tightly and uniformly wound on the transformer. A special tension guiding device is needed to cooperate with the transmission of the coil wire during the winding process of improving the tension. With the development of modern science and technology, the function and structure of the constant tension guiding device of such vertical winding machine are constantly improved, so that it is more efficient and convenient to use.
[0003] However, the existing constant tension guiding device of the vertical winding machine still has the following disadvantages in use: 1. In the guiding process of the coil wire, the existing constant tension guiding device may cause the wire to be loose and unable to be tightened due to the speed difference between the winding machine and the guiding device, and then the coil wire is easy to be loose when wound on the transformer. The ordinary guiding device does not have the function of automatic tension adjustment, and the staff needs to pay attention to the running state of the equipment and the tightness of the wire at all times. Manual adjustment is needed in the first time when the loose phenomenon occurs, which is time-consuming and laborious, and increases the work burden of the staff. 2. When the existing vertical winding machine guiding device adjusts the loose and untightened wire, it needs to be operated from the wire transmission source, and there are many adjusting components, and even the running of the guiding device needs to be stopped for adjustment, thereby reducing the efficiency of winding the transformer coil. 3. In the constant tension guiding process of the coil wire, when the guiding device and the winding machine are of different types, their heights are different, and the adjustment of the guiding direction and angle of the upper end is difficult, which needs to be manually adjusted, thereby increasing the adjustment difficulty of the transmission angle and direction of the guiding device.

[0014] The technical effects and advantages of the present application are as follows: 1. The automatic tension adjusting mechanism is provided, and the outer wall of the coil wire passes between the first guide wheel and the second guide wheel at the bottom of the first mounting frame during transmission. According to the outer diameter size of the coil wire, the first motor is started to rotate the lead screw, thereby driving the second lug to slide in the first limiting groove and extruding the first lug at the bottom of the second connecting frame, so that the second connecting frame rises with the second guide wheel, until the first guide wheel and the second guide wheel extrude the coil wire, and the coil wire is continuously transmitted and wound with the winding machine. During this process, because there is a certain speed difference between the winding machine and the guide wheel, the coil appears loose and untightened state during guiding, at this time the coil will appear a certain sag, and then contact the contact assembly, so that the first motor is excited and started again, driving the rotating lead screw to slide forward again in the first limiting groove, extruding the first lug again, and the contact surfaces of the first lug and the second lug are arc-shaped, so that they can move smoothly when extruding. The first lug is pressed again to rise with the second connecting frame and the second guide wheel, thereby rising with the coil wire and the first connecting frame, so that the first supporting shaft penetrates and compresses the first spring on the first mounting frame. After the whole rises, the coil wire is stretched and tightened, and after being tightened, the coil wire at the rear end sagging restores the tight state away from the contact assembly, and the first motor drive is stopped, so that the guiding device restores the normal constant tension wire transmission, without manual adjustment by the staff. The tension is reduced and the tension is restored automatically at the first time, saving time and effort, and reducing the work burden of the staff; 2.
