Production device for printing fuser film tube

Abstract

The invention discloses a production device for a printing fuser film tube, which comprises a machine frame. A central shaft is arranged on the machine frame, a rotary-extrusion plastic processing device is arranged on the outer side of the central shaft, and a temperature differential stretch stroking processing device is arranged under the central shaft and comprises a moving support. The moving support comprises an inner support and an outer support, a cooling device is arranged on the inner support, a cavity for containing the cooling device is arranged in the central shaft, and a cutting part corresponding to the central shaft and a heating device corresponding to the cutting part are arranged on the outer support. The production device firstly uses rotary-extrusion plastic processing for producing a prefabricated product of the printing fuser film tube, then uses temperature differential stretch stroking processing for removing threaded strips on the surface of the printing fuser film tube, and simultaneously re-corrects straightness and wall thickness of a product. The central shaft is cooled and the cutting part is heated in the temperature differential stretch stroking process, so that martensite phase transformation caused by the stroking processing can be effectively avoided and plasticity of metal materials can be improved.

Description

technical field [0001] The invention belongs to production equipment for printing and fixing film tubes. Background technique [0002] Usually used as printing and fixing film tubes for optical film manufacturing, nanoimprinting, large and small electronic imaging printers, and high-precision printing, polystyrene films and polyimide films with a wall thickness in the range of 0.03 to 0.3 mm are mostly used. In addition, the preparation method of the printing fixing film tube also includes performing electroplating in nickel plating, and adopting a nickel electroforming method in which an electroforming product in which nickel metal is precipitated on a cylindrical matrix is ​​extracted from the matrix. [0003] Since the printing fixing film tube is used in the process of continuous heating, pressurization, cooling, peeling, etc., it is required to have good thermal conductivity and heat resistance. In addition, because it is used as a rotating body, excellent fatigue resis...

AI Technical Summary

Problems solved by technology

However, this processing method still has obvious shortcomings. The printed fixing film tube produced by spinning will produce a large number of spiral stripes on its surface, which seriously affects the surface flatness of the printed fixing film tube. Products of this quality do not meet the Extremely high surface flatness requirements for printing equipment

Moreover, for cylindrical bodies with a processing thickness of less than 0.1mm, the straightness of the processed product is poor and the wall thickness is uneven.
