Abstract

The invention discloses a stepless diameter-alterable roller and a diameter-changing method thereof and belongs to the technical field of winding rollers. The stepless diameter-alterable roller comprises a roller core, supporting frames, supporting roller bodies, a lead screw nut mechanism and a driving mechanism; each supporting frame comprises a supporting roller body, the two ends of each supporting roller body are connected with the corresponding supporting frame, and each of the two ends of the roller core is fixedly provided with one supporting frame; the lead screw nut mechanism is arranged on the roller core in a sleeving mode, the two ends of the lead screw nut mechanism are connected with the supporting frames, and the lead screw nut mechanism is driven by the driving mechanism to move so that the trouble of diameter adjusting of the supporting roller bodies through manual operation can be avoided; and through matching of the driving mechanism and the lead screw nut mechanism, the time and the labor are saved during adjusting. Aiming at the problem that in the prior art, the external-diameter-alterable winding rollers are difficult to adjust, the lead screw nut mechanism is adopted, a motor can automatically control a bi-directional overrun clutch to transfer power for enabling a lead screw to rotate, and through computing control of a numerical control system, the external diameters of the winding rollers can be continuously and accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of winding rolls, in particular to an infinite diameter-reducing roller and a diameter-reducing method thereof. Background technique [0002] Rollers can be used in many technical fields of light industry, such as rubber mats, roll paper films, plastic films, chemical films, etc. Rollers are essential equipment for the above technical applications, and the outer diameter of the rollers determines the product cut size. Different product specifications have different requirements for the slitting size of the roll, and the outer diameter of the roll needs to be adjusted. There are paper rolls that can change the outer diameter on the market, but although the existing paper rolls can change their radius, they are adjusted in stages, the gears are limited, and it is troublesome to adjust. Multiple adjustments and measurements are troublesome and time-consuming. And the accuracy cannot be guaranteed, and when th...
