The version of flute profile of the prior art is that " circular arc at the bottom of tooth top circular arc and tooth is by circumscribed straight line even
Connect ".Because low cost of manufacture, technique are relatively easy, and the producer being manufactured Corrugator roller is widely used, but
It is that production waste is big owing to Corrugator roller vibration is big, noise is big, service life is short, operating rate is slow,
Uneconomical；
In Fig. 1, for tradition profile of tooth mesh schematic representation, Corrugator roller operationally, roller flank profil on the 5th
105 must exist the 4th certain backlash K4 with the 6th lower roll flank profil 106 flank in engaging, only
There is circular arc R at the bottom of tooth top arc radius r and tooth there are differences and could produce rational backlash.And tooth top
At the bottom of arc radius r and tooth, the increasing of arc radius R difference, can accelerate the abrasion of stupefied type, after abrasion, the
The difficulty making paper feed become that diminishes of four backlash K4.Profile contact district concentrates on the point of tooth top and roller seating space
Engaging, both sides are stupefied for arc radius R difference at the bottom of alternately point, tooth top arc radius r and the tooth of engagement transmission
The biggest, path of action is the shortest, and sudden change of acceleration or rotating speed are the highest, and engagement transmission alternating frequency can be accelerated,
Then produce periodic judder and noise.Again due to the existence of flank straight line, corrugating medium is in molding
During, the straight line of flank will clamp core paper can make corrugated board stupefied type shape close to triangle, thus
The i.e. flat compressed intensity of deflection making its cardboard is higher, but its flute profile profile girth is the shortest, hanging down of cardboard
Straight compressive strength i.e. limit pressure is less.Simultaneously because the existence of flank straight line can hinder corrugating medium to take turns in flute profile
Walk in exterior feature, so that the Corrugator roller speed of service is low, the shortcoming that the quick abrasion life-span is short.
For another example application number 200910195871.2, publication date is " Concha Arcae disclosed in 20 days April in 2011
Roller tooth-shaped three-arc structure ", in Fig. 2, three-arc flute profile mesh schematic representation, when Corrugator roller works,
Owing to flank circular arc is the most first cut with tooth top circular arc and roller seating space circular arc, the 4th lower roll flank profil of Corrugator roller
On 104 and the 3rd, roller flank profil 103 can be in full contact state, and its path of action is elongated, and acceleration is dashed forward
Slack-off, engagement transmission alternating frequency can diminish, again due to the existence of flank circular arc, and the 3rd backlash K3
Bigger, in the feelings that tooth top arc radius r is identical with arc radius R difference at the bottom of tooth than the 4th backlash K4
Under condition, corrugating medium can pass in Concha Arcae flank profil freely, and the mill sassafras power between corrugating medium and flank profil subtracts
It is little, so that paper tension reduces；The lower roll flank profil 104 making again Corrugator roller engages with upper roller flank profil 103
During additional dynamic load impact reduce；Therefore the speed of service of Corrugator roller is high, weares and teares little, the life-span
Long；Due to the existence of flank circular arc, the 3rd backlash can become big by K3, and corrugating medium is in forming process
In, flank is not linear type, be arc make corrugated board stupefied type shape close to polygon so that its
The deflection of cardboard i.e. flat compressed intensity step-down, but its flute profile profile girth is elongated, the vertical compression of cardboard
The i.e. limit buckling of intensity is big.
