Description
Technical field
The present invention relates to a kind of forming vacuum case that is used for the dry type paper production line.
Background technology
In the dry type paper production line, be to make the forming web of fiber blanking in the dry type paper production line, and the moulding vacuum tank whether even critical component that is air-flow through negative pressure, directly influence the quality of paper, be the most important thing of whole paper production line.The forming vacuum case in past is owing to can not regulate the uniformity of the online side's each point of control moulding air-flow; So cause the paper became uneven after the moulding even; Even cause the defective of quality, and seriously reducing the yield rate of paper, the increase of defect rate causes the cost of enterprise to increase.
Summary of the invention
The objective of the invention is to above-mentioned existing problems, provide a kind of be used for dry type papermaking simple in structure, make that the fiber blanking is even, adjustability is high, automation and manual operation combine, make paper moulding thickness more evenly, forming vacuum case that precision is higher.
Operation principle of the present invention is: in the forming process of papermaking, even the even of blanking that determined of air-flow makes paper more even; Therefore the uniformity of regulating and control air-flow is most important; Utilize adjustable plate and equal wind bar to regulate control air port size, so just can play the uniformity of regulating air-flow, make that the fiber blanking is even; Improve into the quality of paper, thereby improve the yield rate of paper.
The objective of the invention is to realize like this: lower seal roller, some equal wind bars, air outlets are set, decide plate, adjustable plate, bar shaped tooth bar and stepper motor at the casing of forming vacuum case; The lower seal roller is arranged at the front and back ends of casing respectively, is provided with some the equal wind bars that spacing between transversely arranged layout and per two the equal wind bars can manual adjustments at the casing internal frame of the downside of lower seal roller; The upside of air outlet is set with decides plate; Press from both sides respectively in the top side of deciding plate, bottom side and to establish adjustable plate, bar shaped tooth bar; One end of bar shaped tooth bar is by the gear drive of stepper motor; The other end of bar shaped tooth bar is fixedly connected with adjustable plate, constitutes adjustable plate and is made adjustable plate slide up and down and change the big or small structure of wind seam decide plate by the bar shaped rack drives.
The present invention, the lower seal roller is provided with compressing tablet and diaphragm seal.
The present invention, being arranged at the adjustable plate of deciding the plate top side has four, and every adjustable plate is respectively by being arranged at the bar shaped rack drives separately of deciding the plate bottom side.
The present invention has following good effect: but because equal wind bar is arranged to manual adjustments; When the online side's air-flow of moulding wind speed is inconsistent; Just can regulate the spacing between each equal wind bar, just regulate air port size between equal wind bar, thereby play the effect of regulating the online side's each point of moulding air-flow wind speed; After point measurement each point wind speed is adopted by the online side of moulding; With the pairing stepper motor of PLC controller each adjustable plate of control, let adjustable plate slide up and down, change its wind seam size; Thereby reach the online side's each point of automatic adjusting moulding air-flow wind speed; Make the paper thickness after the moulding more even, precision is higher, has outstanding substantive distinguishing features and obvious improvement.
Therefore, the present invention, tool with simple in structure, make that the fiber blanking is even, adjustability is high, automation and manual operation combine, make paper moulding thickness more evenly, advantage that precision is higher, be applicable to paper moulding in the dry type paper production line.
Following embodiment combines accompanying drawing that the present invention is further described.
Description of drawings
Fig. 1 is the main TV structure sketch map of one embodiment of the present of invention;
Fig. 2 is the left TV structure sketch map of the embodiment of Fig. 1;
Fig. 3 is the plan structure sketch map of Fig. 1 embodiment.
Among the figure, 1, casing; 2, lower seal roller; 3, equal wind bar; 4, air outlet; 5, decide plate; 6, adjustable plate; 7, bar shaped tooth bar; 8, stepper motor; 9, compressing tablet; 10, diaphragm seal.
The specific embodiment
Referring to figs. 1 through Fig. 3, present embodiment is that the casing 1 at the forming vacuum case is provided with the equal wind bar of lower seal roller 2, some 3, air outlet 4, decides plate 5, adjustable plate 6, bar shaped tooth bar 7 and stepper motor 8; Forward and backward lower seal roller is arranged at the front and back ends of casing respectively, is provided with some equal wind bars of transversely arranged layout at the casing internal frame of the downside of forward and backward lower seal roller; All wind bar two auger shell pit is connected in the forming vacuum box body with screw, and the spacing between per two equal wind bars can manual adjustments, is used for manual adjustments moulding wire side air-flow; Be one and decide plate, four adjustable plates above left and right air outlet; Adjustable plate is positioned at decides the plate lower end; And can slide with deciding plate, adjustable plate and bar shaped tooth bar are clipped in respectively decides plate top side, bottom side, and an end of bar shaped tooth bar is by the gear drive of stepper motor; The other end of bar shaped tooth bar is fixedly connected with adjustable plate, constitutes adjustable plate and makes adjustable plate slide up and down and change the big or small structure of wind seam decide plate through step motor control bar shaped rack drives; The lower seal roller is provided with compressing tablet 9 and diaphragm seal 10; Being arranged at the adjustable plate of deciding the plate top side has four, and every adjustable plate is respectively by being arranged at the bar shaped rack drives separately of deciding the plate bottom side.
The present invention, PLC controller control section belongs to known technology.
The course of work of the present invention: when air-flow will flow to air outlet above the forming vacuum case; Above the forming vacuum case, adopt point measurement each point air-flow wind speed; When certain some air-flow wind speed was less than normal, the stepper motor that the adjustable plate of this some below is corresponding was decided plate in PLC controller control lower edge and is slided, and moves adjustable plate; Let the air port increase, thereby improve this air-flow wind speed; Also but manual adjustments increases the distance between two corresponding under this point equal wind bars; If certain some air-flow wind speed is bigger than normal, adjustable plate is moved in stepper motor starting under the control of PLC controller that promptly adjustable plate of this some below is corresponding, lets the air port reduce, thereby reduces this air-flow wind speed; Also can combine manual adjustments to reduce the distance between two corresponding under this point equal wind bars.After measuring several times, forming vacuum case top air-flow reaches evenly whole, so just makes fiber fall to expecting the forming web in the dry type paper production line in the uniform airflow effect, because the fiber blanking is even, makes that the paper moulding thickness on the forming web is more even.
