The specific embodiment
Below in conjunction with Figure of description technical scheme of the present invention is described in detail.
Fig. 1 peels off the schematic diagram of wet web anti-sticking paper structure for high speed air pressure of the present invention.
With reference to Fig. 1, high speed air pressure of the present invention peel off wet web anti-sticking paper structure comprise last week woollen blanket 1 and next week woollen blanket 2 and last week deflector roll and next week deflector roll, as shown in fig. 1, last week, deflector roll was positioned at woollen blanket 1 inboard last week, and with last week woollen blanket 1 contact and make woollen blanket 1 tensioning last week, last week, woollen blanket 1 was when last week, deflector roll rotated, can constitute a drive mechanism that is similar to the closed circulation of driving belt; Equally, next week deflector roll and next week woollen blanket 2 adopt same structure.
Last week, deflector roll comprised paper feed deflector roll 7 and last paper delivery deflector roll 8, and next week, deflector roll comprised paper feed deflector roll 9 and following paper delivery deflector roll 10 down.As shown in fig. 1, woollen blanket last week between last paper feed deflector roll 7 and the last paper delivery deflector roll 81 is used to transmit wet web 13, and same following paper feed deflector roll 9 and woollen blanket next week between the following paper delivery deflector roll 10 2 also are used to transmit wet web 13.Wherein, the line of the center of paper delivery deflector roll 9 and following paper delivery deflector roll 10 under the line at the center of last paper feed deflector roll 7 and last paper delivery deflector roll 9 centers is parallel to, so, this section last week woollen blanket 1 and next week woollen blanket 2 blanket face be parallel to each other, when last week, deflector roll and next week, deflector roll rotated, this section last week woollen blanket 1 and next week woollen blanket 2 cooperatively interact from both sides and rely on frictional force to drive the motion of wet web 13 forward direction.Suitable paper feed deflector roll 7 is set, goes up 8 times paper feed deflector rolls 9 of paper delivery deflector roll, the position of paper delivery deflector roll 10 down, make last week woollen blanket 1 and next week woollen blanket 2 between the suitable wet web 13 that transmits of distance, the while does not produce bigger resistance again.In addition as shown in fig. 1, last week woollen blanket 1 and next week woollen blanket 2 transmit and be provided with boots on the straightway of wet webs 13 and press 3 and suction flat box 5.
With reference to Fig. 1, next week, deflector roll also comprised backrush deflector roll 11, a side of paper feed deflector roll 9 is partial to down in the below that backrush deflector roll 11 is arranged on down paper delivery deflector roll 10, as shown in Figure 1, backrush deflector roll 11 makes woollen blanket 2 paper delivery deflector roll 10 back revolutions on process next week, be circulated back to down paper feed deflector roll 9, contact with wet web 13 once more, realize paper feeding.Side-lower at following paper delivery deflector roll 9 is provided with high speed pneumatic shuttle 6, as shown in fig. 1, the direction d of its high velocity jet gas, upwards and with the angle that line became at the center of following paper delivery deflector roll 9 and backrush deflector roll 11 centers is acute angle, because woollen blanket next week between following paper delivery deflector roll 9 and the backrush deflector roll 11 2 is tensionings, so next week, woollen blanket 2 blanket face was parallel with the line at the center of paper delivery deflector roll 9 and the center of backrush deflector roll 11, thus the direction d of high speed pneumatic shuttle 6 high velocity jet gases with next week woollen blanket 2 the angle a that the blanket face became also be acute angle.In addition, high speed pneumatic shuttle 6 is rotary, its can be by rotate adjusting high speed pneumatic shuttle 6 high velocity jet gases direction d and the angle a that next week, woollen blanket 2 blanket face was become, but the direction d that guarantees high velocity jet gas all the time makes progress and the direction d of high velocity jet gas is an acute angle with the angle a that next week, woollen blanket 2 blanket face was become.Below high speed pneumatic shuttle 6, be provided with broken pond 4 in addition.
So, when occurring breaking the paper alarm, high speed pneumatic shuttle 6 is started working, and it is existing with the air compression, passes through respective nozzles then, direction d according to above-mentioned high velocity jet gas, at a high speed ejection, make wet web 13 with next week woollen blanket 2 peel off, fall into broken pond 4, just solved wet web 13 along with next week woollen blanket 2 enter into deflector roll or other structures next week, cause paperboard.
As a kind of preferred version, the direction d of high velocity jet gas is 37 degree with the angle of the angle a that woollen blanket 2 blanket face is become next week.
Except above-mentioned points, in order better to dispose the wet web of the remnants on the woollen blanket 2 next week, as shown in Figure 1, side-lower at high speed air pressure injection apparatus 6 also is provided with scraper 12, its cutting edge that is used to scrape stripping upwards, and with next week woollen blanket 2 surface contact, and the work edge face c of scraper 12 and backrush deflector roll 11 centers and paper delivery next week deflector roll 10 centers be wired to acute angle, because backrush deflector roll 11 and paper delivery next week deflector roll 10 be woollen blanket 2 tensionings next week, thus work edge face c with next week woollen blanket 2 the angle b that the blanket face became also be acute angle.When the blanket face of all instantly woollen blankets 2 has wet web 13 remaining, the cutting edge of scraper 12 with remnants from next week woollen blanket 2 blanket face peel off, the remnants of being stripped from fall into broken pond 4 along work edge face c.
As a kind of preferred side, scraper 12 is guaranteeing under the aforesaid prerequisite, can rotate a certain angle and corresponding moving a certain distance, so that the cutting edge of scraper 12 all the time with next week woollen blanket 2 contact, the benefit of adjusting angle is, can tackle different situations, realizes better peeling off effect, as preferably, work edge face c can be 37 degree with the angle of the angle b that woollen blanket 2 blanket face is become next week.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
