Description
Technical field
The present invention relates to paper cutter technical field, relate in particular 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 complete with paper cutter.Mechanical type paper cutter early, it pushes away paper process by manually completing, and the accuracy that cuts 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 because the cutting line lines fixed with original painting do not overlap to cause, do not scrap, to enterprise, bring very large economic loss, 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 impact cuts precision, thereby 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 (being cut paper position), for position and the cut paper position of subsequent control feeder provides foundation.In addition, the housing of existing most of paper pulling device of paper cutter directly be in the transmission mechanism in elongated slot in the middle of workbench and be connected, due to the restriction of himself structure, the positional precision after adjusting is in use difficult to keep for a long time.In order to guarantee the positional precision of feeder, in use also can need to measure and calibrate to the initial position of paper cutter and with the distance and position of cutting knife.
At present, the following way of the many employings of positional precision calibration of paper pulling device of paper cutter: first the controller of paper cutter output controlling value drive motors makes feeder move to specified point, then adopt gauge to measure feeder to the actual range of cut paper position, according to controlling value and the gauge measurement data of the controller output of paper cutter, calculate feeder Default Value initial point to the distance of cut paper position again, thereby reach the object of the calibration of distance (after cutter, distance is the distance that feeder Default Value initial point arrives actual cut paper position) after cutter.But, the method is not have the hypothesis of error to calibrate based on transmission mechanism, in fact the transmission mechanism of paper cutter adopts Timing Belt and ball screw to realize transmission more, the kinematic accuracy of feeder is installed by the mounting process of screw mandrel and the error effect of processing technology is larger, in addition along with the loss in use procedure, also can exert an influence to transmission mechanism.Reason to sum up, after existing cutter, range calibration method is added to driving error after cutter in distance, thus the 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 still undesirable.
