Abstract
The utility model discloses a kind of head box side's Taper Pipe, it is made up of upper and lower oralia, inlet plate, epipleural, lower side panel, back side panel, gusset, exit plate, upper oralia, epipleural, back side panel, lower side panel and hypostoma are sequentially connected, connected between epipleural and back side panel and by arc plate between back side panel and lower side panel, the connecting line and the connecting line of arc plate and lower side panel of epipleural and arc plate are parabola.Side plate calculates the utility model according to equal pressure principle formula up and down, design be connected with arc plate line is parabola at side plate up and down, the fair curve calculated more meets actual requirement, using the method for digital control processing when manufacturer's Taper Pipe, make the result of calculation optimization more can fully show, so that the step diffuser headbox designed reaches the requirement along the uniform cloth slurry of paper machine breadth.
Description
Technical field
The utility model belongs to paper making equipment, relates in particular to a kind of part of head box, is mainly used in high-speed paper machine
Head box.
Background technology
Present most head boxs use conical tube, conical tube processing and fabricating tedious process, are welded using multiple hop counts, welding
When be easily deformed and produce other drawbacks.Some head boxs also use square Taper Pipe, but overall structure and manufacture craft are also complete
Kind position.
The content of the invention
The purpose of this utility model is to provide a kind of head box side's Taper Pipe, solves the drawbacks of conventional design and technique.
The purpose of this utility model is realized in the following manner：
A kind of head box side's Taper Pipe, by upper and lower oralia, inlet plate, epipleural, lower side panel, back side panel, gusset, exit plate group
Into, upper oralia, epipleural, back side panel, lower side panel and hypostoma are sequentially connected, between epipleural and back side panel and back side panel with
Connected between lower side panel by arc plate, the connecting line and the connecting line of arc plate and lower side panel of epipleural and arc plate are parabola.
The arc plate cross sectional shape is 1/4 circular arc.
Lower side panel is set by import to outlet successively upward squint.
Welded successively between the epipleural, arc plate, back side panel, arc plate, lower side panel.
Inlet plate and exit plate are adapted with head box lip.
Side plate calculates the utility model according to equal pressure principle formula up and down, designs the company at side plate up and down being connected with arc plate
Line is parabola, and the fair curve calculated more meets actual requirement, and digital control processing is used when manufacturer's Taper Pipe
Method, make the result of calculation optimization more can fully show, so that the step diffuser headbox designed reaches along paper
The requirement of the uniform cloth slurry of machine breadth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 left view.
Fig. 3 is Fig. 1 top view.
Embodiment
A kind of head box side's Taper Pipe as shown in Figure 1-Figure 3, by upper and lower oralia 1, inlet plate 2, epipleural 3, lower side panel 4,
Back side panel 5, gusset 6, exit plate 7 are formed, and inlet plate and exit plate are adapted with head box lip, upper oralia, epipleural 3, after
Side plate 5, lower side panel 4 and hypostoma are fixed on the orifice plate of head box after being sequentially connected, so upper oralia, epipleural 3, back side panel
5th, the hypostoma of lower side panel 4 and the head box orifice plate side of surrounding Taper Pipe, between epipleural and back side panel and back side panel and lower side panel it
Between connected by arc plate 8, the connecting line and the connecting line of arc plate and lower side panel of epipleural and arc plate are parabola, according to equipressure
The parabolic formula that principle formula calculates, the more accurate parabola of geomery is processed with Digit Control Machine Tool, so as to ensure
Paper is quantitatively evenly distributed.The arc plate cross sectional shape is 1/4 circular arc, ensures epipleural and back side panel and back side panel and downside
Plate can rounding off connection, avoid producing dead angle in Taper Pipe.Lower side panel is set by import to outlet successively upward squint.It is described
Welding is adjacent to successively between epipleural 3, arc plate 8, back side panel 5, arc plate 8, lower side panel 4.
Square Taper Pipe width and inlet and outlet size are depending on head box lip width.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model, these are all without the effect and practical applicability for influenceing the utility model implementation.
