Description
Technical field
The invention belongs to calendered film mold transmitting device fields, transport more particularly to a kind of PTFE material plat wide type base film straight line
Luggage is set and its method for correcting error.
Background technique
Using PTFE material calendered film as in the products such as the sealing material of main material, filtering material, composite material, base film is squeezed
Mouth mold out mainly takes round mouth mould and two kinds of flat mouth mold.Flat mouth mold is apparent compared to its advantage for round mouth mould.
It is as follows to delay the calendered film of acquirement its excellent point with the base membrane pressure of flat die extrusion: 1) calendered film width is wider, wide
It is more preferable to spend uniformity；2) precision of the thickness of calendered film can significantly improve；3) vertical and horizontal even intensity degree is obviously improved,
But the process specifications taken are very high, such as without corresponding technique, technology and equipment, can not use the base film of flat die extrusion
It is rolled into ideal calendered film.
Just because of this, now in domestic PTFE seal materials industry, hundreds of processing enterprises are all using circle die extrusion
Rod type blank make calendered film, because of this, the PTFE seal material (being commonly called as raw material band) of these enterprises production is most
The low and middle-grade levels for resting on market, it is even more impossible to raw material band is entered the wrapped insulation applications etc. of semiconductor, army's electricity, appliance cord
High-grade field.
It as shown in Figure 1, is not continuously, to be individually fabricated, including blank 11, barrel into the blank of extruder
12, blank press 13, blank press 13 press down blank 11 in barrel 12, and every blank weight is in 0.5-20kg.
In order to guarantee the quality of calendered film, need to control extrusion base film using corresponding technology.Extruded film is set to exist
It needs to do the following before into calender:
(1) extrusion die of transition, length reach the length 2-40M, best 15-20M of calender average rate continuous production needs；
(2) the extrusion film temperature of transition stage need to be maintained at 15-80 DEG C of range；
(3) extruded film reduces volatilization to the greatest extent in the lubricant of transition stage, and volatile quantity rests in < 2%；
(4) transition stage heat preservation base film there can be no laterally it is rugosity, cannot because accumulation squeeze modification.And ensure extruded film from squeeze
It feeds in the intermediate moving process of calender, in intermediate more fixed position in each transition roller, offset cannot be controlled.
But the state of temperature when entering the base film before calender and having the following problems: that base film squeezes out can not be protected now
It holds, is easy cooling, and lubricant volatilization is fast, maximum problem or the appearance of base film are laterally rugosity, relative in calender
Heart position or so offset, can not enter stack by linear running mode, it may appear that base film is blocked in calender line in calendering
In, base membrane pressure is broken, and the finished product belt width error after calendering increases, uneven thickness, rolls phenomena such as membrane fiber is pressed down, belt
The problems such as scrappage is higher.

Sliding block is filled, installation sliding block is in concave shape, pulley mounting base 33 is set in the guided way 6, the pulley mounting base 33
There are two pulley, the pulleys to slide in the concave shape of installation sliding block for two sides setting；Guided way 6 in three kinds of modes and floating
The connection precision of the axle sleeve 4 in dynamic roller end face is good, and when dancer 3 is gone up and down, the dynamics at two ends of left and right and the consistency of weight are wanted
Well, the depth of parallelism well, will otherwise be difficult to ensure the belt not left and right offset of conveying, smoothly movable forward.
There is tension by the base film of transmission device, but also need to rectify a deviation, base film reaches at traction device position at this time, has
Two kinds of correction modes, with Edge track method for correcting error, it is ensured that the linearity of base film edge smoothly enters to make to squeeze out base film
Calender, need to accomplish enter calender before extrusion base film one of side, linearity is good, deviation to support control ±
In 3mm, in best ± 0.5mm.
The first is set a standard straight-line value, is felt by photoelectric sensor 93 on the basis of some single side of base film
Answer, the straight line value measured compared with standard straight-line value, obtain fiducial value, by device frame 9 ' below idler wheel 91 or so
It is mobile when fiducial value is positive number, to be moved to the left to rectify a deviation, when fiducial value is negative, moves right, rectify a deviation number how many
It is determined according to the size of fiducial value, in ± 1mm, the base film that can not rectify a deviation directly rolls into calender fiducial value error；Fiducial value
Error > 1.5mm, it is primary to rectify a deviation；Such as error > 3mm, after once rectifying a deviation, base film can't be made into before calender, reached
Into ± 1.5mm, need to carry out 1 time or more correction, it is ensured that base film is into calendering procedure leading edge linearity error ± 1.5mm
Within.
Second, on the basis of some single side of base film, a standard straight-line value is set, is felt by photoelectric sensor 93
It answers, the straight line value measured compared with standard straight-line value, obtains fiducial value, rectified a deviation, passed through by correcting error guidance roller 92
The rotation of ball-screw 921 drives nut to move up and down, and nut moves up and down together with fixing axle 923, so that correcting error guidance roller
92 one end inclination, deviation-correcting function is played after inclination, the size of fiducial value determines the gradient of 92 one end of correcting error guidance roller, when than
Compared with value error in ± 1mm, correcting error guidance roller 92 is not necessarily to inclination；Fiducial value error > 1.5mm, 92 one end of correcting error guidance roller
Gradient is at 20 ~ 30 degree；Such as error > 3mm, the gradient of 92 one end of correcting error guidance roller is at 30 ~ 50 degree, it is ensured that base film is into pressure
Prolong within process leading edge linearity error ± 1.5mm, fiducial value is positive number, and the left end of fixing axle 923 rises, and fiducial value is negative
The right end of number, fixing axle 923 rises.
The technology of the present invention protection squeezes out base film to PTFE containing same principle, from flat die extrusion into during calender
It rectifies a deviation to base film and ensures linear running and the Technology design of all transmissions and guiding that designs.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims

It is, on the basis of some single side of base film, sets a standard straight-line value, incuded by photoelectric sensor (93), survey
The straight line value measured obtains fiducial value compared with standard straight-line value, is rectified a deviation by correcting error guidance roller (92), passes through ball wire
The rotation of thick stick (921) drives nut to move up and down, and nut moves up and down together with fixing axle (923), so that correcting error guidance roller
(92) one end tilts, and deviation-correcting function is played after inclination, and the size of fiducial value determines the gradient of correcting error guidance roller (92) one end,
When fiducial value error is in ± 1mm, correcting error guidance roller (92) is not necessarily to inclination；Fiducial value error > 1.5mm, correcting error guidance roller
(92) gradient of one end is at 20 ~ 30 degree；Such as error > 3mm, the gradient of correcting error guidance roller (92) one end is at 30 ~ 50 degree, really
Base film is protected within calendering procedure leading edge linearity error ± 1.5mm.
