Meet, it is proposed that actively and passively flow the concept of control, the groove film drag reduction control that the utility model is related to belongs to passive stream
The category of dynamic control.
The phenomenon that some in nature control to reduce frictional resistance using boundary layer shape is to we provide inspiration, bird
The surface texture of class feather and the structure of shagreen are exactly illustration.Plumage has uniform and parallel distribution groove structure,
The birds of variety classes difference flying speed, the groove structure on its feather surface are also different.And when shark quickly moves about, its table
There is the squama ridge of fine-pitch on skin, there is circus between squama ridge, the arrangement of squama ridge is substantially parallel with flow direction, the squama on sharkskin
Ridge can stablize boundary layer, suffered resistance when reducing quick travelling.
The utility model is related to content is to change boundary layer using groove film to reduce frictional resistance.Groove on film
Scale has drag-reduction effect particularly important influence, with the further development of aeronautical and space technology, how efficiently to manufacture
Go out precision higher applicability is more preferable, drag-reduction effect more preferably groove film, and explore the optimal groove dimensions under different situations
It is the major issue for needing to solve.
Utility model content
The purpose of this utility model is to provide a kind of simple hot pressing film device, solves in the prior art that film laminator structure is excessively
It is lengthy and jumbled, lack the technical problem of of low cost, efficient quick press mold mode：
The utility model proposes solution above-mentioned technical problem technical solution it is as follows：
A kind of simple hot pressing film device, including machine frame at two sides plate, are provided with heating roller, rubber roller and company among two frame plates
Axis, every piece of frame plate outside are each provided with a driving member, and connecting shaft both ends extend through the frame plate of both sides and corresponding transmission
Member Welding is integrated, and bearing and bearing block are also provided with vertical worm screw on the outside of a lateral frame plate, and worm screw top is set
There are turntable and handle, driving member one end is machined with oblique screw thread, coordinates with worm screw and is driven, and the other end is provided with horizontal concrete chute, heats
The both ends of roller are each passed through the vertical slots opened on frame plate, are embedded in the horizontal concrete chute of driving member, heating roller and heating unit
It is connected, groove is carved with surface, and rubber roller end is fixed on frame plate by bearing, which further includes plastic support plate.
Groove is provided with the heating roller, heats the position of roll shaft by vertical chute on frame plate and driving member
Horizontal concrete chute is limited, and rotational handle can control it to move up and down.Heating roller can be by the dismountable shaft end in both ends and middle master
Roll body is formed, and is connected through a screw thread between shaft end and main roll body, the left-handed dextrorotation of both ends screw thread one.So design can be installed conveniently
With dismounting.
The rubber roller both sides are fixed by square shaft bearing with frame plate, and one is each provided with below square shaft bearing
Pressure sensor, rotational handle adjust the pressure of heating roller and rubber roller.
Simple hot pressing film device provided by the utility model, simple for structure, number of components is few, convenient installation, dismounting and more
Change heating roller.Mechanism overall dimensions can change according to required film dimensions, can be as needed when preparing groove film
The film of corresponding size is processed simple and effective, is a kind of controllable thin film preparation process of low cost, simple, can is wall control
The research of drag reduction processed provides support and facility.
