It is characterized in that: described drying tunnel drying system comprises n >=2 grade drying tunnel, m >=1 heating rod is all installed in every one-level drying tunnel.
On this basis, in described drying tunnel drying system towards the moving direction of base band film, the heating rod quantity of installing in every one-level drying tunnel reduce gradually or every one-level drying tunnel in the heating rod quantity of installing identical.
On this basis, the heating rod quantity of installing in described every one-level drying tunnel is identical, and every one-level drying tunnel is also furnished with separately an ECU.
On this basis, in described every one-level drying tunnel, temperature sensor is all installed, the signal of described temperature sensor output controls by corresponding ECU the number that in drying tunnel, heating rod is opened.
The beneficial effects of the utility model: advantage of the present utility model has: 1, adopt in multistage drying tunnel and each drying tunnel many heating rods are installed, can realize the difference of the baking temperature in every one-level drying tunnel, thereby reduce rate of drying; 2, every one-level drying tunnel all disposes independent temperature sensor and ECU, can reduce extraneous interference.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is described further.
The casting machine of the utility model highly heat-conductive carbon/ceramic ceramic chip manufacture use is mainly comprised of following part: fuselage 10, be arranged on the system that unreels 20, formation system 30, drying tunnel drying system 40, winding system 50, the base band film 60 on fuselage 10 successively.
As shown in Figure 1, in the inner side of fuselage 10, let off roll 21 is installed from bottom to up successively, tightens up roller 22, the first guide roller 23.Let off roll 21 can freely be pulled down, to place the let off roll 21 that volume has base band film 60.Let off roll 21, tighten up between roller 22, the first guide roller 23 and fuselage 10 and all can freely rotate, but move axially, be restricted.
At the upper surface of fuselage 10, a casting slurry box 31 is also installed, on casting slurry box 31, also has a discharging opening 32, in order not allow the slurry flowing out from discharging opening 32 flow to fuselage 10, the width of this discharging opening 32 is not more than the width of base band film 60.Downstream direction at discharging opening 32 on fuselage 10 is also provided with a scraper 33, and in order to meet the demand of the substrate of producing different-thickness, the height of this scraper 33 can regulate.Only need to regulate the fine-tuning nut 35 of doctor blade holder 34 upper ends, can change scraper 33 to the distance between base band film 60.
Opposite side at fuselage 10 is provided with base band film winding system 50, and concrete structure is: the second guide roller 51 is installed in the inner side of fuselage 10, and the downside in fuselage 10 inner sides with respect to the second guide roller 51 is provided with wind-up roll 52, can freely dismantle.This wind-up roll 52 is driven by motor 53.
In order to reduce the cooling velocity of substrate, an innovative point of the present utility model is just the mode that drying tunnel drying system 40 adopts multipole drying tunnel series connection, baking temperature to reduce gradually.As shown in the figure, drying tunnel has n >=2 grade, and every one-level drying tunnel includes insulation shell 41, and this insulation shell 41 is arranged on fuselage 10.In insulation shell 41 inside, heating rod 42 is also installed, heating rod 42 numbers in every one-level drying tunnel are m >=1.Wherein heating rod 42 number m can equate, also can reduce gradually along with the m that moves towards of base band film 60.In order to adapt to different demands, the quantity of the heating rod 42 in the utility model in every one-level drying tunnel is identical, in order to realize the independent control to every one-level drying tunnel, a temperature sensor 43 is all installed the insulation shell 41 of every one-level drying tunnel is interior, n ECU 44 is also installed on fuselage 10.The temperature of measuring in drying tunnel by temperature sensor 43, produces a feedback signal, and this signal is delivered to the number that in the interior rear control drying tunnel of ECU 44, heating rod 42 is opened.
Because the baking temperature scope of the casting machine of the utility model highly heat-conductive carbon/ceramic ceramic chip manufacture use is little, thus preferably 2 grades of drying tunnel progression n, and preferably four of the quantity of heating rod 42 in drying tunnel.
