Guide wheel assembly, take-up and pay-off assembly and wire cutting machine

The utility model relates to the technical field of wire cutting, in particular to a guide wheel assembly, a take-up and pay-off assembly and a wire cutting machine. The utility model aims to solve the problem of unstable rotation of the wheel body. In order to achieve the purpose, the guide wheel assembly comprises a mounting sleeve; the rotating shaft is rotatably arranged in the mounting sleeve, and one end of the rotating shaft extends out of the mounting sleeve; the wheel body is connected to one end, extending out of the mounting sleeve, of the rotating shaft; the multiple bearings are arranged, and the multiple bearings are arranged between the rotating shaft and the mounting sleeve; and the limiting pieces are arranged between the two adjacent bearings so as to reduce the rotation jumping of the rotating shaft. The bearings can be separated by using the limiting pieces, so that a certain distance is formed between the bearings, the rotation stability of the rotating shaft is improved, and the rotation
