Fixing device for small transformer capable of preventing coil from loosening before and after winding and cutting

Abstract

The invention relates to the technical field of small transformers, and discloses a fixing device for a small transformer capable of preventing loosening before and after coil winding and cutting. Thefixing device comprises: a winding mechanism, wherein the outer side of the winding mechanism is movably connected with a first cone pulley; and a first rotating column which rotates to cause the movement condition of the winding mechanism, so that the winding mechanism is used for effectively winding the cable, in addition, after the winding quantity is reached, the movement is automatically stopped, the situation that the wound part of the cable is loosened due to continuous rotation of the winding mechanism is avoided, the first rotating column rotates to cause the cutting rod to cut the cable, and when cutting is not performed, the cutter is accommodated in an interlayer between the bottom plate and the outer plate, the cutter is directly exposed to the outside and hurts people, a second rotating column rotates to enable the pressing rod to be close to the cable, the front portion and the rear portion of the cable are fixed, it is avoided that after cutting, the cable is curled, the wound cable is loosened, the winding effect of the cable is reduced, and the workload is increased for subsequent operation.

Description

technical field [0001] The invention relates to the technical field of small transformers, in particular to a fixing device for small transformers that prevents coils from loosening before and after winding and cutting. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage to step up or step down the power to facilitate the transportation and use of power. For the transmission cables used in conjunction with transformers, due to the long length of the whole cable, it is necessary to cut the cables in the actual process to make them reach the qualified size. The existing cables have the following problems during production and cutting: [0003] 1. With the existing cable cutting device, after the cable is cut off, the end of the cable will stay at the cut position, and the cable needs to be pulled out from the cut position again when cutting the next time, and the cable has a certain self-weight. ...

AI Technical Summary

Problems solved by technology

Due to the long length of the whole cable and a certain weight, and the insulating layer on its surface is relatively slippery, it is easy to slip sideways during winding, resulting in gaps between the wire barrels, which affects the overall quality of the wire barrels

At the same time, the existing cable winding device is not equipped with relevant braking and fixing devices. When the winding stops, the cable is easy to slide down due to its own weight, and it is even possible that the electric reel may rotate as a whole, resulting in loosening of the wound cable.
