The invention discloses a folding type take-up spool of a wire drawer. The folding type take-up spool of the wire drawer comprises a take-up roller and a roller drum. The folding type take-up spool of the wire drawer is characterized in that a driving device is arranged on the roller drum and comprises a base, two supports and a driving module; the supports include the first support and the second support; a first semi-cylindrical groove is formed in the first support, and a second semi-cylindrical groove is formed in the second support; a complete cylindrical groove is formed by the first semi-cylindrical groove and the second semi-cylindrical groove, and the end of the roller drum penetrates through the complete cylindrical groove. The driving device is used for driving the roller drum to move in a reciprocating mode, so that thin wires are evenly distributed along the axis of the roller drum, and wire stacking in the prior art is avoided. The supports are designed to be of the split structure, installation and replacement of the roller drum are achieved through the cooperation of the main support and the auxiliary support. During replacing and dismounting, an operator just needs to dismantle bolts through which the second support in the corresponding support set and the base are connected and then horizontally move the second support relative to the first support so as to obtain the roller drum quite easily, and the working efficiency is improved.
