Specific embodiment
In order to which the technical features, objects and effects of invention are more clearly understood, the Detailed description of the invention present invention is now compareed
Specific embodiment, identical label indicates that structure is identical or structure is similar but the identical component of function in the various figures.
Herein, " schematic " expression " serving as examplea, instances, or illustrations " should not will be described herein as " showing
Any diagram, the embodiment of meaning property " are construed to technical solution that is a kind of preferred or more having advantages.
To make simplified form, part related to the present invention is only schematically shown in each figure, they are not represented
Its practical structures as product.In addition, to be easy to understand simplified form, with identical structure or function in some figures
Component only symbolically depicts one of those, or has only marked one of those.
Herein, "upper", "lower", "front", "rear", "left", "right" etc. are only used for indicating the position between relevant portion
Relationship, and they non-limiting absolute position.
A kind of structural schematic diagram of exemplary embodiment of the Fig. 1 to illustrate sheet machine.As shown in Figure 1, small-sized
Paper machine includes forming section 10 and drying section 20.It will be understood by those skilled in the art that for clearer explanation and representing
The correlation of the overall structure of sheet machine and each structure also shows the knot of the other parts of sheet machine in Fig. 1
Structure, but the shape of those structures, assembled scheme etc. are not limited to as shown in the figure.Wherein,
Forming part 10 includes a net cage 12 and a jet pipe 14.Net cage 12 is formed with an accommodation groove (opening for the accommodation groove
Direction should towards the top of attached drawing, but due to angle reason accommodation groove is blocked by its side wall not drawn in the figure).Accommodation groove
Slurry inlet 122 is also provided on one side wall 121.Jet pipe 14 is set to the top of net cage 12, and jet pipe 14 offers flocculation
Agent inlet 142(can be found in Fig. 2).The slurry being made of water, wood pulp can be pumped into accommodation groove by slurry inlet 122,
And flocculant can be injected into accommodation groove by jet pipe 14, it is mixed with paper making pulp, then via the cylinder mould 16 of 12 side of net cage
L Water Paper page is shaped on felt 30.
Flocculant is, for example, polyethylene glycol oxide (PEO), can make that fiber is fully dispersed in the slurry, is uniformly dispersed and prolongs
Slow fiber settles, and is that will be pumped into again accommodation groove after the mixing of water, wood pulp and flocculant, being pumped into operation will affect in previous technique
The effect of flocculant.And above-mentioned forming part 10 establishes two independent channels, can be pumped by slurry inlet 122 by water, wood
The slurry constituted is starched, and flocculant is injected by the flocculant inlet 142 of jet pipe 14, flocculant is made to avoid being pumped into shadow
It rings.Meanwhile compared with previous technique, flocculant is directly injected by accommodation groove by jet pipe 14, makes the penetrating position of flocculant more
Close to cylinder mould 16, keep the effect of flocculant more significant, more evenly, quality is higher for the paper produced.
Drying section 20 can be placed in the side of forming part 10 in actual use, and drying section 20 includes a drying cylinder 22, one
24, heating devices 26 of a dryer hood and an oiling roller 28.
Drying cylinder 22 can rotate counterclockwise in direction shown in arrow along figure, via the carrying roller 29 and drying cylinder 22 of sheet machine
Between felt 30 can by paper on l Water Paper page in drying cylinder 22, even if l Water Paper page separates with felt 30 and is attached at drying cylinder 22
And driven by drying cylinder, this position is the upper paper side of drying cylinder, and drying cylinder 22 drives the rotation of l Water Paper page 30 that can nearly make l Water Paper page after a week
30 leave drying cylinder 22 to complete collection, i.e. the side collection side that is drying cylinder 22.Dryer hood 24 covers at drying cylinder 22, heating device 26
It is set in dryer hood 24 and can calorify the upper paper side of drying cylinder 22, oiling roller 28 is between the collection side and upper paper side of drying cylinder 22
Contact drying cylinder 22.
Because drying cylinder operating temperature is very high, therefore paper side will form vapor, and it is possible that condensing water droplet on drying cylinder 22
The case where being dropped in l Water Paper page, setting heating device can be effectively solved the above problem, and be set to 22 collection side of drying cylinder and
Oiling roller 28 between upper paper side can contact drying cylinder 22, keep 22 surface of drying cylinder more smooth, and l Water Paper page 30 is made to be easier to leave baking
Cylinder 22, avoids or reduces using chemical strippers.
In the embodiment shown in figure 1, one is offered respectively on two opposing sidewalls (not marking in figure) of accommodation groove
A opposite locating slot 124.Jet pipe 14 can be placed in two locating slots 124, and please referring also to Fig. 2, several flocculant notes
Dotted line in entrance 142(figure) uniformly arrange along the extending direction of jet pipe 14, such design, can make flocculant more evenly plus
Enter into accommodation groove 124.
In the embodiment shown in figure 1, the outer surface of oiling roller 28 is with flexible knitting object, and flexible knitting object for example can be with
It is woollen blanket, it can smearing more evenly and contact drying cylinder with woollen blanket.Certainly difference according to the design needs, oiling roller can also use
Other designs, such as mao roller is directlyed adopt as oiling roller.
In the embodiment shown in figure 1, heating device 26 includes row's heating tube 262, the extending direction of heating tube 262
Can be parallel to the axial direction of drying cylinder 22, and row's heating tube 262 being circumferentially arranged along drying cylinder 22, the heating of this frame mode
Effect is more preferable, can effectively solve the problems, such as to drip in dryer hood.
Although not each embodiment only includes one it should be appreciated that this specification describes according to various embodiments
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solutions in the various embodiments may also be suitably combined for bright book, and forming those skilled in the art can be with
