The longitudinal extension length of the short sword of the rip cutting of correspondence and the first protection portion is near equal, and the short sword of rip cutting adds that the lifting surface area of the first protection portion equates with the lifting surface area of the long sword of crosscut is approaching.
The second protection portion that on the roller outer circumference surface, also has the projection that axially is symmetrically distributed in the first protection portion outside.
The described second protection portion is parallel to the described first protection portion and ring roller outer circumference surface distributes.
In the shape by die-cutting device, the monoblock type cross cutting roller that the utility model provides is as the cutting rotor, the anvil rod that has bed course on outer circumference surface is pressed over, drive rotation by power set, and roller is applied certain pretightning force by pre-tightening mechanism, utilize the roll extrusion cutting to form product with required form.
Because the height of projection of the described first protection portion, the second protection portion equates with the height of projection of die-cutting rule, and two symmetrically arranged first its axial spacings of protection portion are cut material width greater than quilt, and the second protection portion is distributed in outside the first protection portion.Therefore, though set up first, second protection portion of projection on the roller outer circumference surface, first, second protection portion does not participate in can not influenced the operate as normal of die-cutting rule to cutting the cutting of material.
When the cross cutting roller carried out cutting operation, first, second protection portion was bearing on the anvil rod outer circumference surface all the time.Most of shock loading that cutting action produces is born by the described first protection portion, reduces the infringement to blade, plays the effect of protection blade.Balanced action plays in the described second protection portion, guarantees the running of cross cutting roller steadily, avoids the impact of roller swing to die-cutting rule.Therefore,, can prolong the service life of die-cutting rule greatly, reduce the operation and maintenance cost, produce good effect by first, second protection portion is set at the cross cutting roller.
Especially to having the die-cutting rule of complicated shape, for example have the short sword of long sword of crosscut and rip cutting, its protective effect is more remarkable.Because in the rotation cutting process, die-cutting rule begin to cut cut material, to material is cut off moulding and at last with cut in each stage that material separates, its lifting surface area constantly changes, the shock loading of being born also constantly changes.Even in the same stage of cutting process, because sword is long, tread is different, different blade lifting surface area differences, the shock loading of being born are also different.This shows that if do not take safeguard measure, die-cutting rule integral body or local pole are easily impaired.
When in the arranged outside of the short sword of rip cutting the first identical protection portion of longitudinal length, in each stage of cutting process, the first protection part has been carried on a shoulder pole most of shock loading, reduces the influence of load change to blade.Equate with the lifting surface area of the long sword of crosscut is approaching owing to the short sword of rip cutting adds the lifting surface area of the first protection portion simultaneously, thereby make the shock loading of bearing on short sword of rip cutting and the long sword of crosscut be tending towards even distribution.
In addition, consider that when cutting cut material and be sealed on the closed-loop of die-cutting rule, make sometimes to produce vacuum state in the closed-loop, cut material and stick on the die-cutting rule thereby cause.For preventing that above-mentioned phenomenon from taking place, in the middle of described closed-loop, be provided with steam vent, described steam vent is communicated with discharge duct, and described discharge duct is opened on outside the described closed-loop.
The monoblock type cross cutting roller that the utility model provides, each parts impacts, swings the infringement to the cross cutting blade in the time of reducing to cut, and prolongs the service life of cutter, reduces the operation and maintenance cost, and is respond well.
