Abstract
The invention relates to an absorption structure of a corrugator roller, which comprises a barrel of a lower roller, a deep duct formed in the circumference of the barrel of the lower roller, and at least one sector groove formed between the barrel surface of the lower roller and the deep duct, wherein the sector grooves are formed in a herringbone shape. The absorption structure of the corrugator roller has the advantages that: the quality problem of corrugated paperboards, which is caused by insufficient absorption force of corrugated papers when the edges of the corrugated papers fall at the port of the circumferential sector groove and around the middle of the circumferential sector groove.
Description
Technical field
The present invention relates to a kind of corrugation roller, relate in particular to the adsorption structure of this corrugation roller.
Background technology
Paper through the moulding of 1 pair of corrugation roller after, the centrifugal force that the running of the stupefied roller of the easy invar of corrugated paper after the moulding produces and throw off the corrugation roller, throw off the corrugated board of corrugation roller and can't finish the compound of follow-up gluing and facial tissue, need quite reasonable positive negative pressure structure design, corrugated paper is fixed on the stupefied tooth of corrugation roller reliably finishes gluing and compound, therefore every pair of corrugation roller all must the design adsorption structure.
By Fig. 1,2 as seen: paper 1 enters top roll 2 and forms corrugated paper 8 with lower roll 3 backs, compressed air forms negative pressure by the 4 coupled circumference fan grooves 7 of the deep hole road on the lower roll 3 on corrugation roller 3 surfaces, so corrugated paper 8 tightly is adsorbed on the grooved of lower roll 3, finish the gluing on 9 pairs of stupefied tops of corrugated paper of glue spreader, carry out facial tissue 6 and corrugated paper 8 compound through pressure roller 5 again.
The problem of Cun Zaiing like this: one, when the widthwise edges of paper just at the right time at L
2Or L
1Fan-shaped notch on the time, because of the blast effect makes corrugated paper can't gluing because of not having fixed bit to be out of shape to cause, so the corrugated board edge can have problems; The 2nd and since the fan-shaped fluted shaft of circumference between identical distance L is all arranged
3So, leave the stupefied roller running of circumference fan groove centre farthest whole circle invar generation centrifugal force and make the absorption affinity deficiency and corrugated paper tightly is fixed on the stupefied type of corrugation, influenced corrugation quality in gluing, recombination process, produce unfavorable corrugated board.Among the figure: L: roll surface length; L1: head and the tail air draught slot pitch; L2: the multiple length of adjacent air draught slot pitch; L3: adjacent air draught slot pitch.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of adsorption structure of corrugation roller, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: the cylindrical shell of lower roll; In the cylindrical shell circumference of described lower roll, the deep hole road is arranged; Also comprise: between the drum surface of lower roll and deep hole road, the fan groove of at least one; Arrangement between the described fan groove is " people " word shape.
Compared with prior art, the invention has the beneficial effects as follows: thoroughly solved the corrugated paper edge and dropped on fan-shaped notch of circumference and the middle circle of circumference fan groove, caused corrugated paper because of the not enough corrugated board quality problems that cause of absorption affinity.
Description of drawings
Fig. 1 is that corrugated paper forms structure chart;
Fig. 2 is a corrugation roller adsorption structure schematic diagram in the prior art;
Fig. 3 is a structure chart 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:
As seen from Figure 3: the present invention includes: the cylindrical shell of lower roll 30; In the cylindrical shell circumference of described lower roll 30, deep hole road 4 is arranged; Also comprise: between the drum surface of lower roll 30 and deep hole road 4, the fan groove 70 of at least one; Arrangement between the described fan groove 70 is " people " word shape.
Operation principle of the present invention (as Fig. 1, shown in Figure 3): paper forms corrugated paper through the corrugation roller, the compressed air mouth is by roller body duct 4, through chevron shaped air draught groove 70 corrugated paper is absorbed and fixed on the lower roll 3 again, finish again glue spreader 9 and pressure roller 5 with to the gluing of corrugated paper 1 and facial tissue 8 and compound, finish the overall process of whole corrugated paper adsorption forming.
Design of the present invention has changed the arrangement theory of traditional fan groove circle on circumference, be arranged on the corrugation roller roll surface with chevron shaped in an orderly manner but interlock, thereby avoided and the equitant possibility of corrugation paper edge, the centrifugal force that simultaneously can the stupefied roller running of invar produce to the fixing influence that produces of corrugated paper absorption, has therefore been avoided because of paper edge and the quality problems that adsorption tank is overlapping and the not enough disengagement of corrugated paper absorption affinity corrugation roller causes on circumference.
Claims (1)
