Abstract
The utility model discloses a vacuum roller squeezing device which comprises a carpet, a vacuum squeezing roller forming a pressing area with a drying cylinder and a machine frame. The machine frame is provided with an upper supporting device in a hinged mode, the upper supporting device is provided with a vacuum squeezing roller, an inner cavity of the vacuum squeezing roller is provided with a vacuum chamber, a lower supporting device is fixed on the machine frame, and a compressing air bag is connected between the upper supporting device and the lower supporting device. The vacuum roller squeezing device further comprises a pressure stabilization tank, pressure stabilization liquid is filled in the pressure stabilization tank, the upper portion of the pressure stabilization tank is connected with a compressed air pipeline, and the bottom of the pressure stabilization tank is communicated with the compressing air bag through a liquid pipeline. The pressure stabilization liquid is filled in the pressure stabilization tank, compressed air is slowly filled in the pressure stabilization tank and presses the pressure stabilization liquid to the compressing air bag, and accordingly the compressing air bag is full of the pressure stabilization liquid, due to incompressibility of liquid, compression of the compressing air bag is relatively stable, vibration does not easily occur, evenness of paper is improved, and transverse quantitative differences of paper are greatly reduced.
Description
Technical field
The utility model relates to a kind of dewater unit of toilet paper machine, particularly relates to a kind of vacuum carrying roller pressing device.
Background technology
Vacuum carrying roller pressing device is the main dehydration part of high speed toilet paper machine, and it directly has influence on mass dryness fraction, performance and the manufacturing paper with pulp property of page.Vacuum carrying roller pressing device comprises woollen blanket, forms suction press roll, the frame of nip with drying cylinder, be hinged with the upper support device on the frame, on the upper support device suction press roll is installed, the roller shell of suction press roll is provided with through hole, be provided with vacuum chamber in the inner chamber of suction press roll, the contact-making surface of the installation site of vacuum chamber and suction press roll and woollen blanket adapts, be fixed with the lower support device on the frame, be connected with pressurised airbag between upper support device and the lower support device, pressurised airbag is connected with compressed air line.Suction press roll and drying cylinder form nip, by pressurised airbag is pressurizeed, the lifting of control suction press roll, thereby the size of control linear load, but because the gas in the pressurised airbag has compressibility, under the pressurized operation state, very easily be subjected to external action to produce vibration, cause nip pressure unstable, cause the page dehydration uneven, form paper defects, can't guarantee product quality.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of mechanical oscillation are little, page dewaters uniform vacuum carrying roller pressing device.
For solving the problems of the technologies described above, the utility model comprises woollen blanket, suction press roll with drying cylinder formation nip, frame, be hinged with the upper support device on the frame, on the upper support device suction press roll is installed, be provided with vacuum chamber in the inner chamber of suction press roll, be fixed with the lower support device on the frame, be connected with pressurised airbag between upper support device and the lower support device, it is characterized in that described vacuum carrying roller pressing device also comprises vacuum tank, be marked with voltage stabilizing liquid in the vacuum tank, vacuum tank top is connected with compressed air line, and the vacuum tank bottom is communicated with pressurised airbag by liquid line.
After adopting said structure, inject voltage stabilizing liquid in the vacuum tank, in vacuum tank, slowly pass into compressed air, compressed air is pressed into pressurised airbag with voltage stabilizing liquid, makes all to be full of voltage stabilizing liquid in the pressurised airbag, because the Incoercibility of liquid, therefore the pressurization of pressurised airbag is relatively stable, be difficult for producing vibration, improved the evenness of page, greatly reduced the quantitative difference of banner of page.
Described voltage stabilizing liquid is water.
The cornerite of described vacuum chamber and woollen blanket is 180 °, and the aperture of vacuum chamber is large, and swabbing action is obvious, can deviate from the large quantity of moisture of page, improves the mass dryness fraction of page.
The roller shell surface of described suction press roll is provided with the encapsulate layer, is evenly equipped with glue-line through hole and blind hole on the encapsulate layer, improves the water separation capability of pressing device.
Described suction press roll is provided with drip tray at the rear of nip, the water that throws away in the suction press roll surface holes is caught and is drained, and improves the mass dryness fraction of page, can reduce steam consumption when oven dry section carries out drying entering, and reduces consuming, and saves cost.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional schematic of suction press roll.
The specific embodiment
As depicted in figs. 1 and 2, vacuum carrying roller pressing device comprises woollen blanket 1, suction press roll 3 with drying cylinder 2 formation nips, frame 7, be hinged with upper support device 71 on the frame 7, suction press roll 3 is installed on the upper support device 71, be evenly equipped with through hole 5 on the roller shell 4 of suction press roll 3, be provided with vacuum chamber 6 in the inner chamber of suction press roll 3, the contact-making surface of the installation site of vacuum chamber 6 and suction press roll 3 and woollen blanket 1 adapts, vacuum chamber 6 is 180 ° with the cornerite of woollen blanket 1, the aperture of vacuum chamber 6 is large, swabbing action is obvious, can deviate from the large quantity of moisture of page, improves the mass dryness fraction of page.Be fixed with lower support device 72 on the frame 7, be connected with pressurised airbag 8 between upper support device 71 and the lower support device 72, vacuum carrying roller pressing device also comprises vacuum tank 10, be marked with voltage stabilizing liquid in the vacuum tank 10, vacuum tank 10 tops are connected with compressed air line 9, vacuum tank 10 bottoms are communicated with pressurised airbag 8 by liquid line 15, voltage stabilizing liquid is water, under the compressed air effect, hydraulic pressure is entered pressurised airbag 8, make and all be full of water in the pressurised airbag 8, because the Incoercibility of liquid therefore the pressurization of pressurised airbag 8 is relatively stable, is difficult for producing vibration, improve the evenness of page, greatly reduced the quantitative difference of banner of page.
Suction press roll 3 is provided with drip tray 14 at the rear of nip, the water that throws away in suction press roll 3 blind holes 13 is caught and is drained, and improves the mass dryness fraction of page, can reduce steam consumption when oven dry section carries out drying entering, and reduces consuming, and saves cost.
L Water Paper page or leaf 20 enters the nip of suction press roll 3 and drying cylinder 2 formation under woollen blanket 1 drives before, vacuum draw effect through vacuum chamber 6, moisture is successively through glue-line through hole 12, through hole 5 enters in the vacuum chamber 6, thereby slough large quantity of moisture, improved web dryness, when entering nip, avoided the conquassation of wet web, behind the nip of excess pressure uniformity, a moisture part of deviating from is pumped, and a part is taken away by woollen blanket 1, also has quite a few blind hole 13 by suction press roll 3 surfaces to throw away through drip tray 14 and drains, web dryness improves greatly like this, can reduce steam consumption when oven dry section carries out drying entering, consume thereby reduce, save cost.
