Summary of the invention

The technical problem to be solved in the present invention is to provide the stupefied type Corrugator roller of a kind of M, mix rational tip circle, end circle and pitch, the stupefied triplex board thickness of M preparing is up to 8.5～11mm, and the physical index of its cardboard can reach the physical index of 5 layer paperboards or 7 layer paperboards completely;

And in the situation that body paper is identical, the contracting paper rate of the stupefied triplex board of M is lower by 30% than the contracting paper rate of 5 layer paperboards or 7 layers of paper.Make superduty clamp carton, by appropriate design, load-bearing can reach more than 3 tons, meets export standard, can for wood, exempt to fumigate with paper.

The relation of the empty van compression strength of carton and body paper, cal(l)iper, corrugation rate can be used following equation expression:

P = 0.05874 P_{m} \sqrt{tZ}

P: Compression Strength of Corrugated Box (N);

Pm: the comprehensive ring crush intensity (N/cm) of corrugated board body paper;

P_{m} = \frac{Σ R_{n} Σ {CR}_{mn}}{15.2}

Rn---facial tissue ring crush intensity test value (N/0.152m)

Rmn---corrugating medium's ring crush intensity test value (N/0.152m)

C---the single tooth profile girth/pitch of corrugation shrinkage factor C=

T: cal(l)iper (cm)

Z: corrugated case headroom Zhou Bianchang (cm);

From formula above, we can find out, after carton size is fixed, the compression strength P that improves empty van can only improve Pm value or cal(l)iper t value, improve Pm, mainly that physical index, body paper grammes per square metre, the number of plies of corrugated board, the several aspects of corrugation rate that improve body paper are done, and these aspects all will make cost rise in a large number, the development of Zhe Dui company and resources conservation are all disadvantageous; Therefore in order to improve the pressure resistance of empty van, just need to solve problem from improving cal(l)iper;

The method that improves thickness is:

One, utilize existing stupefied high cardboard to combine to increase the number of plies as combination or the combination such as CBE or ABE of five laminates such as AA, AB on the market, this method can make cost rise in a large number, is unfavorable for the sustainable development of company;
