The device drives the differential ring in a friction mode, uses a motor to transmit power through the synchronous belt wheel, and can improve the running speed through electric operation control. Because the friction mode is not suitable for high speed, the heating value is large, the abrasion of the friction belt is increased, and the service life is shortened.

One motor drives the synchronous pulley, and the other motor drives the synchronous pulley, so that power transmission is realized.
Description
Technical Field
The utility model belongs to the technical field of the reel of wire drawing machine, in particular to store up line and draw reel.
Background
The existing metal wire drawing process flow is that after a plurality of drawing processes, the metal wire is finally wound on a plastic disc or a take-up reel to form a finished product or a semi-finished product.
When the metal wire after being drawn is wound on a plastic disc or a take-up reel, the winding speed of the metal wire cannot be equal to the drawing speed of the preorder drawing production line. In the initial stage and the final stage of the metal wire wound on the plastic disc or the take-up disc, the winding speed has a stage of acceleration or deceleration.
And when the winding of one plastic disc or take-up reel is finished and the next empty disc is replaced, the winding speed of the metal wire is 0. While the metal wire in the preceding drawing line is still in drawing at a certain speed. If the plastic disc or the take-up reel needs to be replaced and the pre-drawing process needs to be stopped, the production efficiency is seriously influenced, and the waste of resources is caused.
The traditional solution is: the metal wire is drawn to a final specification product, a large spool is used for winding and winding, and after one large spool is fully wound, another empty spool is replaced, so that the minimum downtime can be realized, and the yield can be improved; then the full large spool is turned to a coil separating and taking up position, the wire on the large spool is paid out by a pay-off machine, and then the wire passes through a tension mechanism and a straightener and finally is coiled into a small coil.
Therefore, there is a need to overcome the contradiction between the take-up speed of the metal wire in the take-up stage and the wire feeding speed of the metal wire in the drawing process, and there is a need to develop a winding drum, which can store the metal wire in the winding drum when the take-up speed of the metal wire in the take-up stage is less than the wire feeding speed of the metal wire in the drawing process, so as to avoid the shutdown of the previous drawing process.
