Description
Technical field
The present invention relates to paper cutter technical field, particularly relate to a kind of paper cutter accuracy calibrating method.
Background technology
In printing mechanism field, paper cutter, through printing process overall process, is one of indispensable key equipment.Along with the development of papermaking and packaging industry, the application of paper cutter is towards the future development of diversification, and the purposes of paper cutter is not limited to cutting of paper, and the cutting of material such as plastic sheeting, leather, corrugated paper, cloth can have been come with paper cutter.Mechanical type paper cutter comparatively early, it pushes away paper process by manually completing, and the accuracy cutting location can not be satisfactory.At present, the automaticity of paper cutter is more and more higher, the cut paper precision of paper cutter is greatly improved, but be still difficult to reach customer requirement, particularly at exquisite packaging industry, often cause because lines that cutting line and original painting are fixed do not overlap and scrap, bring very large economic loss to enterprise, and cause multiple negative effect.
From the 26S Proteasome Structure and Function of paper cutter, feeder is the vitals of paper cutter, and the size of its position error directly affects and cuts precision, thus affects the quality of paper cutter cropping of products.Therefore, before paper cutter dispatches from the factory, all to calibrate it, obtain the initial position of feeder and the distance of cutting knife (i.e. cut paper position), for the position of subsequent control feeder and cut paper position provide foundation.In addition, the housing of existing most of paper pulling device of paper cutter is directly connected with the transmission mechanism be in the middle of workbench in elongated slot, and due to the restriction of himself structure, the positional precision after adjusting in use is difficult to keep for a long time.In order to ensure the positional precision of feeder, in use also can need to the initial position of paper cutter and and the distance and position of cutting knife measure and calibrate.
At present, the positional precision calibration of paper pulling device of paper cutter adopts following way: first the controller output controlling value drive motors of paper cutter makes feeder move to specified point, then gauge is adopted to measure the actual range of feeder to cut paper position, the controlling value exported according to the controller of paper cutter again and gauge measurement data calculate the distance of feeder Default Value initial point to cut paper position, thus the object of the calibration of distance (after cutter, distance is the distance of feeder Default Value initial point to actual cut paper position) after reaching cutter.But, the method does not have the hypothesis of error to carry out calibrating based on transmission mechanism, in fact transmission mechanism many employings Timing Belt of paper cutter and ball screw realize transmission, the kinematic accuracy of feeder is larger by the error effect of the mounting process and processing technology of installing screw mandrel, in addition along with the loss in use procedure, also can have an impact to transmission mechanism.To sum up reason, after existing cutter, driving error is added to after cutter in distance by range calibration method, thus error after calibration is still larger, cuts precision still not high.This problem is particularly outstanding in large scale product cuts, although equipment is calibrated, cuts uniformity and precision is still undesirable.
