Zhang Jinhang is dehydrated, such as 201120431150.X, CN201620148536.2, by the squeezing being arranged on the squeeze dehydration unit
Moisture removal on paper, but the weak point of this device be by the active force that roller and suction roll are mutually extruded, it is easy to makes paper
Open and be pasted onto after extrusion on pressure roller or suction roll, other mechanisms can only be reset by external force or on the apparatus by paper
Lift off, not only increase manufacturing cost, inefficiency is also easily destroyed to paper surface；Although leading in equipment component
Cross and pore is set in pressure roller separates with pressure roller realizing paper, but pore makes pressure roller surface irregularity, is being dehydrated
During easily the marking is left to the surface of paper, affect outward appearance of the paper mold into after.
Utility model content
This utility model overcomes shortcoming of the prior art, there is provided a kind of quick-dehydration device for papermaking, can be high
The paper that makes of rate safety is separated with pressure roller, and the speed of dehydration is also of a relatively high with efficiency.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions：One kind is used for papermaking
Quick-dehydration device include by first driving means drive pressure roller, by the first pneumatic means drive suction roll, second
The slewing rollers that driving means drive；
The pressure roller outer layer is provided with Stainless Steel layer；
The suction roll outer layer is provided with water accepting layer, and receipts water cavity is provided with inside suction roll, receives water cavity by receiving water hole with water suction
Layer connection, is received water cavity and is connected with Negative pressure machine by negative tube；
Air cavity is provided with inside the slewing rollers, turning roll surface is provided with pore, and the pore is connected with the air cavity, described
Air cavity is connected with the aerator outside slewing rollers.
Further, suction roll upper end contacts with extruding wheel, and extruding wheel is connected to the second pneumatic means by axle
On power output shaft.
Further, dehydration device also includes being located at the moisture content determining device on slewing rollers top, and is located in pressure roller
Plus thermoelectric wire, moisture content determining device by controller with add thermoelectric wire controlling switch connect.
Further, pressure roller lower section is provided with Wiper blade, and the Wiper blade top is provided with bristle.
The beneficial effects of the utility model are：(1) it is separated with pressure roller beneficial to paper, by slewing rollers to paper and squeezing
Gap jet between roller, makes paper be separated with pressure roller；(2) connect with Negative pressure machine in suction roll, it is negative that Negative pressure machine is produced
Pressure makes the water of suction roll water accepting layer quickly be sucked in suction roll, makes water accepting layer keep drying；(3) first pneumatic means drive
Suction roll can be driven to move, realize adjusting the pressure between suction roll and pressure roller.
Description of the drawings

Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
As shown in figure 1, a kind of quick-dehydration device for papermaking include by first driving means drive pressure roller 1,
Suction roll 3, the slewing rollers 4 of the second driving means driving driven by the first pneumatic means 2；
The outer layer of pressure roller 1 is provided with Stainless Steel layer；
The outer layer of suction roll 3 is provided with water accepting layer 5, and receipts water cavity 6 is provided with inside suction roll 3, receives water cavity 6 by receiving water hole with water suction
Layer 5 is connected, and is received water cavity 6 and is connected with Negative pressure machine by negative tube, it is preferred that the upper end of suction roll 3 contacts with extruding wheel 10, is squeezed
Pinch roller 10 is connected on the power output shaft of the second pneumatic means 14 by axle；
Air cavity 7 is provided with inside slewing rollers 4, the surface of slewing rollers 4 is provided with pore 8, and pore 8 is connected with air cavity 7, air cavity 8 with turn
Connect to the aerator outside roller 4；
Preferably, dehydration device also includes being located at the moisture content determining device 9 on the top of slewing rollers 4, and is located in pressure roller 1
Plus thermoelectric wire, moisture content determining device 9 by controller with plus thermoelectric wire controlling switch connect, moisture content determining device 9 survey Jing
The surface moisture of paper 13 of pressure roller 1 is crossed, if excess moisture, is started plus thermoelectric wire, to improve the surface temperature of pressure roller 1,
Make dewatering efficiency higher.
Preferably, the lower section of pressure roller 1 is provided with Wiper blade 12, and the top of Wiper blade 12 is provided with bristle, and Wiper blade 12 will be pressed
The water squeezed on roller 1 is shaved, and prevents the upper band water of pressure roller 1, weakens the dewatering efficiency of the device.
