Abstract
The invention relates to a corrugated roller tooth type three-arc structure, which comprises: a tooth shape; the tooth profile includes: a tooth crest arc with radius R and a tooth bottom arc with radius R; also comprises a section of arc with radius R connected with the tooth top arc with radius R and the tooth bottom arc with radius R respectivelyInConnecting the arcs; the radius is RInOne end of the connecting arc is circumscribed with the addendum arc with the radius of RInConnecting the other end of the arc with a tooth bottom circle with a radius of RArc circumscribed; the invention has the beneficial effects that: the corrugated roller has the advantages of reducing contact angles and paper tension, increasing the compressive strength of the paper board, reducing resonance and noise, having strong adaptability to high-speed lines and long service life.
Description
Technical field
The present invention relates to a kind of corrugation roller, relate in particular to the tooth type structures of this corrugation roller.
Background technology
The corrugation roller is the heart component of sewing thread on card, its stupefied shape designed rationality and accuracy of manufacture, and wear-resisting, withstand voltage degree has substantial connection to the speed of service of its service life and sewing thread on card.The tooth profile curve will directly determine the intensity (BCT, FCT) and the corrugation rate TUR of carton.
The version of profile of tooth of the prior art is " the tooth top circular arc is connected through circumscribed straight line with circular arc at the bottom of the tooth ".Because of low cost of manufacture, technology are simple relatively, and extensively adopted by the producer of manufacturing corrugation roller.
Like Fig. 1, shown in Figure 2: during the work of corrugation roller, input fluting medium 101 in the middle of two rollers through top roll 102, lower roll 103 engagement roll compacting flatiron moulding, forms corrugating medium 104; In corrugating medium's 104 forming processes; Must there be certain clearance in top roll 102 with lower roll 103 flank in engagement, and is single to the tooth engagement, and the flank profil contact zone concentrates on the point gearing of tooth top and roller seating space; The stupefied alternately point in both sides for the engagement transmission; Acceleration sudden change or rotating speed are higher, and engagement transmission alternating frequency can be accelerated, and then produces periodic judder and noise.Having only radius is that circular arc B there are differences and could produce rational backlash at the bottom of the tooth top circular arc A of r and the tooth that radius is R.And radius is the increasing of circular arc B difference at the bottom of the tooth top circular arc A of r and the tooth that radius is R, can quicken the wearing and tearing of stupefied type, after the wearing and tearing, and the difficulty that diminishes paper feed is become of backlash.Owing to the existence of flank straight line, corrugating medium 104 is in forming process again, and the straight line of flank will be clamped core paper and hinder it and in the labyrinth, walk, thereby make the speed of service low, and limit velocity is 180～200 meters/minute, and wearing and tearing are accelerated, and the life-span is low.Among the figure: H: tooth depth α: profile angle T: circular pitch θ: minute of angle.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of corrugation roller flute profile three-arc structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention includes: flute profile; Flute profile comprises: radius is a circular arc at the bottom of the tooth top circular arc of r, the tooth that radius is R; Comprise that also one section is that the radius that circular arc joins at the bottom of the tooth top circular arc of r and the tooth that radius is R is R with radius respectively
InConnect circular arc; Described radius is R
InOne end of connection circular arc and the tooth top circular arc that radius is r are circumscribed, and radius is R
InCircular arc is circumscribed at the bottom of the other end of connection circular arc and the tooth that radius is R.
Compared with prior art, the invention has the beneficial effects as follows: reduce contact angle and paper tension, increase cardboard compression strength, reduce resonance and noise, strong to high-speed line adaptability, corrugation roller high life.

Fig. 2 is the tooth type structures sketch map of corrugation roller in the prior art;
Fig. 3 is a structural representation of the present invention;
Fig. 4 is operation principle signal of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Visible by Fig. 3, Fig. 4: as to the present invention includes: flute profile; Flute profile comprises: radius is circular arc B at the bottom of the tooth top circular arc A of r, the tooth that radius is R; Comprise that also one section is that the radius that circular arc B joins at the bottom of the tooth top circular arc A of r and the tooth that radius is R is R with radius respectively
InConnect circular arc C; Described radius is R
InOne end of connection circular arc C and the tooth top circular arc A that radius is r are circumscribed, and radius is R
InCircular arc B is circumscribed at the bottom of the other end of connection circular arc C and the tooth that radius is R.Among the figure: H: tooth depth α: profile angle T: circular pitch θ: minute of angle.
When the corrugation roller was worked, the lower roll flank profil 301 and the top roll flank profil 304 of corrugation roller were in complete contact condition, and corrugating medium can be passed in the corrugation flank profil freely like this, and the mill sassafras power between the corrugating medium and the flank of tooth reduces, thereby paper tension is reduced; The lower roll flank profil 301 of corrugation roller and the impact of the additional dynamic load in top roll flank profil 304 engagement processes are reduced; Reduce noise and vibration thereby reach.
Visible from accompanying drawing 4: traditional tooth type structures and the three-arc structure; Under the situation that arc radius at the bottom of their tooth top arc radius and the tooth equates; Backlash 305 of the present invention is bigger than traditional tooth type structures backlash, can adapt to the paper of low grammes per square metre, and area of contact fragile paper very much not.
Design of the present invention has changed the outside circle of traditional corrugation roller flute profile and has been connected simple structure with the flexible tangent line of crossing at the bottom of the tooth; But adopt outside circle to be connected new structure with the circumscribed arc of flexible mistake at the bottom of the tooth, when the corrugation roller was worked, upper corrugated roller can contact with the lower corrugated roller engagement fully like this; Resonance and noise had both been reduced; Improve corrugation roller limit velocity to 250～350 meter per seconds, can reduce the wearing and tearing of stupefied shape again, increased corrugation roller service life.
