Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing 1-7.
With reference to Fig. 1 or 2 or 3, a kind of thin film oven, including hinged case lid 1 and cabinet 2, case lid 1 and cabinet 2 can be certainly
By opening and closing, since film itself is easily-deformable, in order to which film is dried uniformly through baking oven, which further includes being used for
Several deflector rolls 3 being moved in cabinet 2 of driving film, 3 array of deflector roll in cabinet 2, the end of deflector roll 3 with motor phase
Even, film is moved horizontally by the synchronized rotation of deflector roll 3, is equipped with for the bottom surface of dry film, between the adjacent deflector roll 3 not high
In the air intake passage 4 and lower air-out passage 5 of deflector roll 3, the section of air intake passage 4 and lower air-out passage 5 is rectangle, and and deflector roll
3 be that heating rod is equipped in air intake passage 4 with the sequentially circular array of deflector roll 3, air intake passage 4, deflector roll 3 and air-out passage, into
The side in wind channel 4 is equipped with several air inlets 41, and outside air becomes thermal current by the heating of heating rod and flows from air inlet 41
Enter, the top of lower air-out passage 5 is equipped with several lower air outlets 51, this make thermal current have to pass through film bas could from it is lower go out
Air port 51 is flowed out, and ensure that drying effect；For the surface of dry film, case lid 1 is upper equipped with being connected to lower air-out passage 5
Air intake passage 6, case lid 1 are equipped with the up-draught mouth 61 for being connected to and being open towards deflector roll 3 with upper air inlet channel 6, also set on case lid 1
There is upper air outlet 7, thermal current is flowed out from uptake, is blowed to film surface, then flow out from upper air outlet 7, is completed film surface
It is dried, case lid 1 is equipped with driving blower 8, can guide thermal current outside baking oven followed by air inlet 41, lower air outlet
51, lower air-out passage 5, upper air inlet channel 6, up-draught mouth 61 and upper air outlet 7, are finally reached outside baking oven, are formed one thin
The dry thermal cycle in film two sides.
With reference to Fig. 5, in order to improve the maximum utilization efficiency of driving blower 8, air entry and the upper air inlet channel of blower 8 are driven
6 are connected, and the inflatable mouth of driving blower 8 is connected with up-draught mouth 61, drive the air blowing of blower 8 and air suction function that can obtain benefit
With simultaneously because lower air-out passage 5 is connected with upper air inlet channel 6 by hose 11, driving blower 8 can effectively improve thermal current
Flowing velocity, to improve drying efficiency.
With reference to Fig. 3 or 7, in order to take thermal current sufficiently the moisture on film out of, upper air outlet 7 is located on case lid 1, and
The bottom surface of case lid 1 is vertical with the axis of upper air outlet 7, hot steam rising principle can be made full use of to make thermal current spontaneous in this way
Outflow accelerates exhaust velocity, while thoroughly taking steam out of, and moisture accumulations is not allowed to moisten the film dried again in baking oven,
Drying effect is destroyed, the quantity of upper air outlet 7 is several, and array is located in the gap of up-draught mouth 61, increases thermal current
Instantaneously can displaced volume, improve drying efficiency.
With reference to Fig. 3 or 6, in order to improve the thermal current flow velocity for drying film surface, 61 radial section shape of up-draught mouth
Shape be it is trapezoidal, trapezoidal shorter upper bottom edge is located at the opening of up-draught mouth 61, close deflector roll 3, narrower according to fluid process
Faster separate of local flow velocity, trapezoidal design can be such that the instantaneous circulation area of thermal current gradually becomes smaller, and flow velocity is gradually accelerated,
Thus it is fastest when blowing to film, the moisture of film surface is more rapid and better taken away, to accelerate thermal cycle speed, is improved
Drying efficiency.
With reference to Fig. 3 or 6, since film has the easily-deformable speciality with once deformation as waste product, if thermal current exists
Flow velocity is excessive when dry film surface, then can apply deformation force to film, film is easily at waste product, but flow velocity is too low and can reduce heat
Circulation rate reduces efficiency, so up-draught mouth 61 must be aligned towards one end of deflector roll 3 with the axis of deflector roll 3, this can make
When must blow to film from up-draught mouth 61, deflector roll 3 can be very good to provide a supporting role to film, offsets thermal current and gives film
Downward power, to guarantee that film is indeformable.
With reference to Fig. 1 or 7, since the feature easy to stick of film influences to lead to guarantee that film is not sticky on deflector roll 3
3 moving in rotation film of roller, deflector roll 3 are equipped with frosted coating 31, in this way it is possible to prevente effectively from film is viscous to stick deflector roll 3, make deflector roll 3 with
The mobile film of most suitable speed, improves drying efficiency.
With reference to Fig. 4, in order to accelerate the speed of thermal cycle, case lid 1, which is parallel at the central axes of deflector roll 3, is equipped with partition, partition
Divide upper air inlet channel 6 for two chambers, the quantity of blower 8 driven to be two and set up 1 both ends of case lid separately, respectively with two chambers
It is connected, upper air inlet channel 6 and lower air-out passage 5 are also two to correspond to driving 8 quantity of blower, and are symmetrically arranged at 1 liang of case lid
End, upper air inlet channel 6 and lower air-out passage 5 are connected by hose 11, this is greatly increased to thermal current in lower air-out passage 5
Suction and blowing force to thermal current in upper air inlet channel 6, improve thermal cycle rate, improve baking oven efficiency.
It is located at middle line in order to accelerate the speed that thermal current is discharged from baking oven with reference to Fig. 4 or 7 on case lid 1 and is equipped with outlet
Blower 81, the air entry of outlet blower 81 are connected to upper air outlet 7, and the gas outlet of outlet blower 81 is in communication with the outside, by going out
The air blast function of gas blower 81 can accelerate thermal current to flow into the flow velocity of air outlet 7, to accelerate thermal cycle rate, quickly
The moisture of film tow sides is taken away, drying efficiency is accelerated.
With reference to Fig. 1 or 7, due to containing moisture in thermal current, moisture damages outlet blower 81, outlet blower 81 in order to prevent
It being detachably connected with upper air outlet 7 by connector 9, water-absorbing sponge 91 is placed in connector 9, water-absorbing sponge 91 is replaceable,
This effectively extends the service life of outlet blower 81 and baking oven, and due to connector 9 can with water-absorbing sponge 91 replaceable, baking oven
It is provided with Convenient inspection, can preferably handle the moisture that drying generates, improves drying efficiency.
Specific implementation process: the outer air of baking oven becomes thermal current by the heating of heating rod, under the suction of driving blower 8
Enter in cabinet 2 from the air inlet 41 on air intake passage 4, to deflector roll 3, constantly mobile film bas is dried, subsequently into
Lower air-out passage 5 enters upper air inlet channel 6 by hose 11, is arranged again from the air outlet of driving blower 8 by the sucking of driving blower 8
Out, deflector roll 3 is blowed to from the outflow of up-draught mouth 61, dried behind the surface of film under the suction of outlet blower 81 from upper air outlet
7 discharges, return to outside baking oven, and then carry out thermal cycle next time.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
