Its main components are primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc. according to their uses.
现有的变压器在生产过程中往往需要使用绕线机进行绕线，现有的绕线机的线筒通常自然挂载在轴上，往往需要配合旋转阻尼装置使用，外置式的阻尼产生装置会占用较大的空间造成绕线机的体积增加，而内置式的阻尼产生装置通常使用橡胶筒产生摩擦力，使用的寿命较短,而且这两种阻尼装置都存在使用时间增加部件磨损导致阻力逐渐衰弱的问题。In the production process of existing transformers, winding machines are often required for winding. The bobbins of existing winding machines are usually naturally mounted on the shaft and often need to be used in conjunction with a rotary damping device. The external damping generating device will occupy a large space and increase the volume of the winding machine, while the internal damping generating device usually uses a rubber tube to generate friction and has a short service life. In addition, both damping devices have the problem of gradually weakening resistance due to wear of components over time.

Compared with the friction force generating scheme using rubber wearing parts, the use of a rotating block to push the three friction plates can make the degree of the three friction plates more consistent, thereby obtaining a good service life, and the deformation state of the spring plate can be adjusted by the bolt and nut to determine the relative rotational resistance between the rotating drum and the bracket. The output damping force is adjustable and suitable for universal promotion and use; the bolt adopts a rotating block to connect the spring plate, and the force of the spring plate will cause the rotating block to generate a force toward the outer circle of the bolt. This feature has self-locking ability, which is conducive to optimizing the locking effect; as the wear time increases, since the contact area between the friction plate and the rotating drum is always the same, the resistance generated is also the same, avoiding the problem of the damping of the existing damping device gradually weakening with use time.

工作原理，该高频变压器生产用线圈绕线机的线筒阻尼产生装置，螺栓306旋转将会带动与其螺纹连接的转动块303在其轴向方向上移动，随后压缩弹片301让弹片301带动块端轴701旋转，块端轴701旋转将会带动转块7旋转，转块7旋转将会把与其接触的片垫块601向外撑，摩擦片6此时将会与转筒5的内壁接触，由于摩擦片6和转筒5内壁相互摩擦，让转筒5和托座8之间产生旋转阻力，此特征赋予转筒5外侧的线筒1较为恒定的旋转阻力，因为即使随着磨损时间的增加，摩擦片6与转筒5的接触面积总是相同的，所产生的阻力也是相同的，转筒5两端的端环2将转筒5限制在托座8和端盖4外部，避免转筒5在托座8的轴向方向上移动，807外圆上的开口用于提供维修拆卸3时操作空间；Working principle: the bobbin damping generating device of the coil winding machine for high-frequency transformer production, the rotation of the bolt 306 will drive the rotating block 303 threadedly connected thereto to move in its axial direction, and then compress the spring sheet 301 to allow the spring sheet 301 to drive the block end shaft 701 to rotate, and the rotation of the block end shaft 701 will drive the rotating block 7 to rotate, and the rotation of the rotating block 7 will push the sheet gasket 601 in contact with it outward, and the friction plate 6 will contact the inner wall of the rotating drum 5 at this time. Due to the mutual friction between the friction plate 6 and the inner wall of the rotating drum 5, a rotational resistance is generated between the rotating drum 5 and the bracket 8. This feature gives the bobbin 1 on the outside of the rotating drum 5 a relatively constant rotational resistance, because even with the increase of wear time, the contact area between the friction plate 6 and the rotating drum 5 is always the same, and the resistance generated is also the same. The end rings 2 at both ends of the rotating drum 5 restrict the rotating drum 5 to the outside of the bracket 8 and the end cover 4, to prevent the rotating drum 5 from moving in the axial direction of the bracket 8, and the opening on the outer circle of 807 is used to provide operating space for maintenance and disassembly 3;
调整旋转阻力时，松开螺母305，通过扳手旋转螺栓306让螺栓306螺纹连接的转动块303沿着螺栓306的轴向方向移动，此时移动的转动块303将会压缩弹片301，弹片301叉状部分一端的转动块303内部的块轴304不插入托座8中的盖定孔805或端盖4中的盖定孔405内部，通过调整弹片301的压缩程度决定转块7的旋转力量，从而控制转块7旋转压动片垫块601作用到摩擦片6上的力，达到调整转筒5旋转阻力的效果。When adjusting the rotational resistance, loosen the nut 305 and rotate the bolt 306 with a wrench to allow the rotating block 303 threadedly connected to the bolt 306 to move along the axial direction of the bolt 306. At this time, the moving rotating block 303 will compress the spring piece 301. The block shaft 304 inside the rotating block 303 at one end of the fork-shaped part of the spring piece 301 is not inserted into the cover hole 805 in the bracket 8 or the cover hole 405 in the end cover 4. The rotational force of the rotating block 7 is determined by adjusting the compression degree of the spring piece 301, thereby controlling the force of the rotating block 7 rotating to press the plate pad 601 to act on the friction plate 6, thereby achieving the effect of adjusting the rotational resistance of the rotating drum 5.
