Take-up reel and cable splitting machine with take-up reel

The invention relates to a take-up reel and a cable splitting machine with the take-up reel. The cable splitting machine comprises the take-up reel. The take-up reel comprises a winding core with the axis extending in the left-and-right direction. The winding core comprises a fixed cable clamping piece. A movable cable clamping piece is movably assembled on the part, on the inner side of the fixed cable clamping piece, of the winding core in the radial direction of the winding core in a guiding manner. A cable clamping cavity is defined by the fixed cable clamping piece and the movable cable clamping piece. The cable clamping cavity is provided with a circumferential cavity opening located in the peripheral face of the winding core and used for cable heads of corresponding cables to penetrate and to be installed in the circumferential direction of the winding core, the included angle of the cable heads on the inner side and the outer side of the circumferential cavity opening is larger than 90 degrees, and the bending degree of the cable heads taken down from the take-up reel is smaller than 90 degrees. Thus, the cable heads do not need to be shorn down, the procedure of shearing down the cable heads is omitted, and materials are saved.
