Intaglio press baking oven heater
[technical field]
The utility model relates to a kind of printing equipment, particularly a kind of baking oven heater of set type intaglio press.
[background technology]
The set type intaglio press adopts electrically heated baking oven heater to dry the material film mostly at present, the structure of baking oven heater is, outside blast pipe sucks heating cabinet with fresh air under the centrifugal blower suction, be provided with electric heating tube in the heating cabinet, electric heating tube energising work, produce hot blast, centrifugal blower blows out hot blast from the blower fan blowing mouth then, via warm-air pipe, import baking oven at last, the material film is dried.The shortcoming that this kind structure exists is: baking oven, air inlet, air outlet position are more concentrated, because structural limitations, warm-air pipe length is longer, thermal loss is inevitable, for remedying this thermal loss, the general increase heating power that adopts solves, and is example with present 10 looks, 1000 type printing machines, and its heating power is 120KW; Also have, whole heater comprises external heat case, the platform that heating cabinet and centrifugal blower are installed, support etc., complex structure, takes up room greatly, and during the machine operation, rack-mount blower fan can produce vibrations, and noise is big.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model be to provide a kind of simple and compact for structure, noise is little, can significantly improve the intaglio press baking oven heater of the efficiency of heating surface.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
Intaglio press baking oven heater, comprise baking oven casing, heating tube and blower fan, the baking oven casing is made up of static housing and active box two parts, be provided with the closed cavity of bringing air port and row's blowing mouth in the described active box, the described active box sidewall in the closed cavity outside is provided with exhaust outlet, air inlet is communicated with described blower fan, it is characterized in that: described heating tube is arranged in the described active box closed cavity, with the corresponding one by one setting of described blowing mouth.Described blower fan is fixedly mounted on the intaglio press wallboard.
The utility model is set directly at electric heating tube in the baking oven, heat energy utilization rate height, avoided the prior art heating cabinet to centrifugal blower, arrive the thermal loss of warm-air pipe again, significantly improved the efficiency of heating surface, with 10 looks, 1000 type printing machines is example, its heating power only needs 60KW, compares with the 120KW of prior art, can energy-conservation 50%; Also have the utility model to cancel external heat case, platform, support etc., centrifugal blower directly is fixedly mounted on the intaglio press wallboard, so simple and compact for structure, because the general employing of intaglio press wallboard is cast iron materials,, blower fan can reduce noise greatly so being fixed on the wallboard.

[specific embodiment]
As Fig. 1, shown in 2, this intaglio press baking oven heater, comprise baking oven casing 1, heating tube 7 and blower fan 3, blower fan 3 is fixedly mounted on intaglio press wallboard 2 outsides, baking oven casing 1 is made up of static housing 8 and active box 6 two parts, be provided with the deflector roll 11 of material conveying film 10 in the static housing 8, be provided with the closed cavity 12 of bringing air port 4 and row's blowing mouth 9 in the active box 6, described active box 6 sidewalls in closed cavity 12 outsides are provided with exhaust outlet 5 (see figure 1)s, air inlet 4 is communicated with described blower fan 3, described heating tube 7 is arranged in the described closed cavity 12, with the corresponding one by one setting of described blowing mouth 9.
This intaglio press baking oven heater is work like this, and blower fan is dried and entered the closed cavity of active box from air inlet, and heating tube energising work so hot blast blows out from blowing mouth, is dried the material film, and air draft is sent by exhaust outlet then.
