One inlays steel pipe type internal-suction type Corrugator roller

Technical field

The utility model relates to a kind of Corrugator roller, and especially one inlays steel pipe type internal-suction type Corrugator roller.

Background technology

Paper is shaping through a pair Corrugator roller, corrugated paper after shaping easily throws off Corrugator roller because of the centrifugal force of Corrugator roller running generation, the corrugated board of throwing off Corrugator roller cannot complete follow-up gluing and the compound of facial tissue, need quite reasonable positive/negative-pressure structural design, the stupefied tooth that corrugated paper just can be made reliably to be fixed on Corrugator roller completes gluing and compound, and therefore often pair of Corrugator roller all must design adsorption structure.

The adsorption structure of current Corrugator roller has three kinds: outer suction, internal-suction type and malleation bleed type.The lower corrugated roller of wherein vacuum internal is processed with equally distributed semicircular arc, fan-shaped air draught groove in proportion, and is connected with equally distributed wind inlet on roll body wall.The strong exhausting of high pressure positive blower, by air-suction duct, be close to adsorption cover in lower corrugated roller roll body end face, wind inlet on roll body wall makes Corrugator roller and outside space form negative pressure, again by the air draught groove on lower corrugated roller, make shaping after corrugated paper be close on the lower corrugated roller of fast turn-around, complete gluing and compound working procedure continuously.Its advantage: Corrugator roller adopts semicircular arc or fan-shaped air draught groove, energy-saving and cost-reducing, air draught is effective, corrugation forming, flat crushing strength is high, and one side paperboard surface is smooth attractive in appearance, without cover suction, leads claw single-side machine and stays annular indentation on corrugated board in process of production.And be used widely.

But because the air draught groove on internal-suction type lower corrugated roller mainly adopts the Eight Character trough or fan groove, (as figure mono-, figure bis-); This groove is discontinuous at roll surface circumferencial direction, cannot fill lead paper lead pawl, there is following shortcoming like this:

Uneven at circumferencial direction suction, high grammes per square metre Corrugator roller body paper suction is caused the out-of-flatness of Corrugator roller body paper paper feed not and easily, crumpled, thus causes corrugation shaping bad;

Because nothing leads pawl, Corrugator roller is when running up, and easily throw off Corrugator roller because of the centrifugal force of Corrugator roller running generation, the corrugated board of throwing off Corrugator roller cannot complete follow-up gluing and the compound of facial tissue.

Due to above shortcoming, inhale Corrugator roller in current fan-shaped groove, Eight characters groove etc. and be mainly used in middle low speed Corrugator roller board production, for high speed corrugating rollor board production, need a kind of new air draught groove structure.

Prior art is difficult to meet production of machinery needs, in order to solve above-mentioned Problems existing, the utility model proposes one and inlaying steel pipe type internal-suction type Corrugator roller.

For realizing this technical purpose, the technical solution adopted in the utility model is: one inlays steel pipe type internal-suction type Corrugator roller, comprises the cylindrical shell of lower roll; Deep hole road and steel pipe is had in the cylindrical shell circumference of described lower roll; An annular air draught groove is at least provided with between the drum surface and deep hole road of lower roll; Arranged in parallel between described air draught groove.

Further, described annular air draught groove width 0.8 ~ 3.5mm, annular air draught groove depth 15 ~ 30mm, the outside dimension of described steel pipe is Φ 15mm ~ Φ 30mm, wall thickness 1 ~ 2mm, and steel pipe longitudinal opening width is 4 ~ 8mm.

Compared with prior art, the utility model has following beneficial effect: this inlays steel pipe type internal-suction type Corrugator roller, solve at circumferencial direction suction uneven, high grammes per square metre Corrugator roller body paper suction is caused not and easily, the out-of-flatness of Corrugator roller body paper paper feed, to crumple, thus cause the shaping bad situation of corrugation;

Solve without leading pawl Corrugator roller when running up, easily throw off Corrugator roller because of the centrifugal force of Corrugator roller running generation, the corrugated board of throwing off Corrugator roller cannot complete follow-up gluing and the compound of facial tissue;

Solve without steel pipe cannelure internal-suction type Corrugator roller inlet scoop that size is not uneven, the shortcoming of processed complex;

Both the Corrugator roller speed of service having absorbed positive-pressure type and outer suction is fast, and feature easy to process, possesses again internal-suction type Corrugator roller and save energy and reduce the cost, the feature that air draught is effective.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Figure of description 1 ~ 8, in the utility model embodiment, one inlays steel pipe type internal-suction type Corrugator roller, comprises the cylindrical shell of lower roll; Deep hole road 4 and steel pipe 8 is had in the cylindrical shell circumference of described lower roll; An annular air draught groove is at least provided with between the drum surface and deep hole road 4 of lower roll; Arranged in parallel between described air draught groove.

Further, described annular air draught groove width 0.8 ~ 3.5mm, annular air draught groove depth 15 ~ 30mm, the outside dimension of steel pipe 8 is Φ 15mm ~ Φ 30mm, wall thickness 1 ~ 2mm, and steel pipe longitudinal opening width is 4 ~ 8mm.

Action principle of the present utility model is: paper forms corrugated paper through Corrugator roller, compressed air mouth is by roller body deep hole road 4, through parallel annular air draught groove, corrugated paper is absorbed and fixed on lower roll 3 again, complete again glue spreader 9 and pressure roll 5 with to the gluing of corrugated paper 1 and steel pipe 8 and compound, complete the overall process of whole corrugated paper adsorption forming.

The utility model adopts special steel pipe 8 to be mounted in lower roll duct 4, the advantage done like this:

Adopt the structure of Fig. 5, due to duct 4, be all identical with the opening that groove 7 is connected in any position, due to the corrugated paper of Corrugator roller, to produce large wicket amplitude variation dynamic larger like this, if the size L4 between groove is uniformly distributed at whole roll surface, there will be two kinds of situations:

1), gate width inhales when producing not enough, cause lean now to one side, then to the other stupefied

2), wicket width both sides leak out, and cause centre stupefied

In order to solve the problem, middle groove dimensions L6 so just can only be adopted to be greater than both sides groove dimensions L5, and such air draught groove is not uniformly distributed on Corrugator roller, easily occurs improper distortion when Corrugator roller is produced, and causes corrugated board waste product.

Therefore, adopt and inlay steel pipe 8 to the structure in deep hole road 4, man-hour can be added at steel pipe like this, make middle width B 2 larger than B1, thus can be uniformly distributed at the groove 7 of Corrugator roller.

The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
