Double-ended Mask Beam Cutting Machine

Abstract

The invention relates to a double-end-surface film bundle cutter. A base is connected with a driving device, a transmission device and cutting devices in sequence; two sets of cutting devices are arranged in parallel; a sliding fixture is arranged in the middle position of the two sets of cutting devices; the cutting devices include blade fixing devices and blades arranged on the blade fixing devices; blade protective covers are arranged at the outer peripheries of the blades; openings for passing through film bundles are formed in one sides, facing operators, of the blade protective covers; the sliding fixture includes slide rails arranged on the base and parallel to the side surfaces of the blades; limiting stoppers are arranged at one ends, near the blades, of the slide rails; and the upper ends of the slide rails are connected with pushing fixtures through slide blocks. The double-end-surface film bundle cutter solves double-end-surface synchronous cutting problem of hollow fiber polysulfone films (film bundles) through two cutting equipment and the sliding fixture between the two cutting equipment, satisfies the parallelism and the length requirement of double end surfaces when guaranteeing levelness of single end surface, reduces the ratio of such bad qualities as intermingling of broken wires in the film bundles, improves the product quality, and improves the working efficiency.

Description

technical field [0001] The invention relates to the field of medical device production equipment, in particular to a double-end mask beam cutting machine. Background technique [0002] The field of membrane dialysis (permeation) has high requirements on the end face and length of the membrane, especially the hollow fiber polysulfone membrane used in the dialyzer in the pharmaceutical industry. At present, the domestic cutting equipment for this kind of film only has single-end cutting equipment, which requires the operator to cut one end and then cut the other end according to the length requirement. It is easy to destroy the flatness of the cut end faces, and more importantly, it is extremely difficult to control the parallelism of the double end faces. Therefore, the quality of the film is affected to a certain extent. Contents of the invention [0003] According to the above disadvantages, the object of the present invention is to provide a double-end synchronous cutti...
