Device for cutting off soft pipeline

Abstract

The invention discloses a device for cutting off a soft pipeline. The device comprises an air cylinder, a traction base, a blade, guide rods, springs, a driving chuck, a static chuck and a bearing frame. The air cylinder is fixed to the bearing frame, the traction base is connected with a push plate of the air cylinder, the driving chuck is connected with the traction base through the guide rods and the springs, the blade is fixed to the traction base, the static chuck is fixed to the bearing frame, and the static chuck and the driving chuck are clamping mechanisms capable of being opened and closed for each other. According to the device for cutting off the soft pipeline, notches are perpendicular and free of burrs and yielding tensile deformation, the relative length error is smaller than 0.5%, and the work efficiency is improved by more than 20% by an average; and the structure is simple and compact, high equipment integration is facilitated, the workshop land use cost is reduced, and a technical module can be laid for designing of a standard and full-automatic production line.

Description

technical field [0001] The invention belongs to the field of equipment manufacturing for flexible plastic pipeline product packaging, and in particular relates to a cutting device for the supporting equipment for rewinding and reeling such as pipes, wires or belts. Background technique [0002] In the packaging process of the flexible plastic pipeline manufacturing industry, preforms with a length of tens of thousands of meters need to be wound on the paper disc or spool of the "I"-shaped rotating body. The linear speed of this type of upper disc generally reaches 200-400m / min , the pipeline needs to be cut into a predetermined length of 100-meter-level small-packaged finished product. For applications in the field of high-precision electronics, it is required that the result of this simple "cutting" action be that the cut is vertically flat, the pipeline itself has no yielding tensile deformation, and the relative error of the total length is less than five thousandths. ...

AI Technical Summary

Problems solved by technology

[0003] The typical way to solve this problem in the past is to cut off manually with scissors. Such simple and frequent alternating actions of acceleration and deceleration not only lead to high labor intensity, easy to paralyze attention, and low production efficiency, but also have large errors in the cutting position (length), and are easy to cut. Beveled, resulting in yield tensile deformation, end-users waste a lot of space, and can not meet the physical and chemical electrical performance quality requirements in the field of high-precision electronics
