Circular twisting mechanism of thread trimmer

Abstract

The invention discloses a wire shearing machine circulatory stranding mechanism. With the wire shearing machine circulatory stranding mechanism adopted, fast and circulatory multi-wire stranding can be realized. The wire shearing machine circulatory stranding mechanism comprises a rack; the rack is in bearing connection with an input shaft; the input shaft is in dynamic connection with a hollow shaft through an accelerating gear; the hollow shaft is in rotary connection with the rack and can axially slide; a main shaft is coaxially arranged in the hollow shaft; the main shaft is provided with an axial stripe-shaped groove; a round pin radially connected on the hollow shaft is inserted into the stripe-shaped groove so as to drive the main shaft to rotate; the input shaft is in key connection with a cam; a smoothly-changed profile at the side surface of the cam abuts against the tail end of the main shaft so as to drive the main shaft to move axially; the head end of the hollow shaft is provided with a conical surface; the head end of the main shaft is connected with a clamp seat which is symmetric with respect to the axis of the main shaft; two ends of the clamp seat are respectively hinged with a middle portion of a clamp; hinging portions of the clamp seat and the clamps are provided with torsion springs for driving the clamps to keep clamping states; and the tail ends of the clamps abut against the conical surface of the hollow shaft. With the wire shearing machine circulatory stranding mechanism adopted, circulatory multi-wire stranding can be realized.

Description

technical field [0001] The invention relates to an attachment for a thread trimmer. Background technique [0002] The wire trimmer is a machine that strips the plastic sheath and the metal core of the wire, etc., and there are different suitable models due to the different wire diameters and wire materials and compositions. During the processing of wire plugs, manufacturers of wire plugs often need to peel off the plastic skins at both ends of the wires to expose the metal wires, and then perform splicing and winding work. At present, the wire stripping operation in production mostly adopts the method of man-machine combination. Although this type of method can realize wire stripping, in the special preparation procedure, the process requires that the stripped wire head be twisted into a strand. , the current wire stripping machine can not quickly and effectively carry out the circular multi-wire twisting, and often requires manual operation, and the production efficiency i...
