The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

With reference to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model is the vertical coater oven of a kind of bilayer, comprises the double-layer heat insulation casing and is arranged on backwind tube, the blowing mouth in the insulation casing.

Insulation casing 2 inside are divided into two halves up and down, and two halves is provided with common blast pipe 14 up and down, and two halves is divided into left and right sides two halves again respectively through dividing plate 11 simultaneously up and down; Be disposed with four backwind tubes from top to bottom; Be respectively the backwind tube A1 of the first half, the backwind tube B4 of the latter half, backwind tube C5 and backwind tube D7, backwind tube A1 and backwind tube D7 separately with one group of radiator, 8 import UNICOMs; Common and the other two groups of radiators of backwind tube B4 and backwind tube C5 8 import UNICOMs in addition; Shared these two groups of radiators 8, each radiator 8 is provided with a waste discharge tracheae 15, waste discharge tracheae 15 and clean room UNICOM;

The first half is along walking to expect that route is provided with six groups of air knife formula blowing mouths 3; Six groups of 3 whiles and blow box B13 UNICOM of air knife formula blowing mouth; Blow box B13 and blower fan B12 UNICOM; Two groups of radiators of the import of blower fan B12 and the first half 8 outlet UNICOMs, the gas that six groups of air knife formula blowing mouths 3 blow out is realized circulating with blower fan B12 through backwind tube and radiator separately;

The latter half is along walking to expect that route is provided with the poroid blowing mouth 6 of two networkings and four groups of air knife formula blowing mouths 3 (every group is two blowing mouths to blowing); Wherein, Be provided with the poroid blowing mouth 6 of a networking near charging aperture and the discharging opening respectively separately; Charging aperture and discharging opening far-end are provided with four groups of air knife formula blowing mouths 3, these six groups of blowing mouths simultaneously with blow box A10 UNICOM, blow box A10 and blower fan A9 export UNICOM; The outlet UNICOM of two groups of radiators 8 of blower fan A9 import and the latter half, the gas that these six groups of blowing mouths blow out is realized circulation through backwind tube and radiator 8 with blower fan A9.

The operation principle of the utility model is: be formed by stacking in upper and lower two-layer baking oven; The upper and lower half divides each to be divided into two parts by dividing plate 11, and two high-speed fans in the casing are worked simultaneously, in insulation casing 2, forms air negative pressure; Four radiator 8 inside are connected with high-temperature medium; With air heat, last hot-air blows to the printable fabric surface through two blow boxs (10,13) and all blowing mouths (3,6) successively, and the printable fabric surface is dried.The portion of hot air is through waste discharge tracheae 15 entering clean rooms afterwards, and a part of in addition hot-air passes dividing plate 11 through four backwind tubes and gets into the right side casing participation secondary cycle that radiator is housed.Like Fig. 1, shown in Figure 2, form hot air circulation respectively at upper box and lower box inside.

Like Fig. 1; The opening of four backwind tubes in the casing of left side be the casing middle position in the left side all; Improve the air circulation speed of each several part in the casing of left side greatly through this setting, thereby guaranteed the uniformity of temperature in the casing, reduced the aberration that causes because of the temperature difference.

Like Fig. 2, stock is by upwards getting under the double-deck baking oven bottom, left, and totally 12 groups of blowing mouths are dry through two-layer baking oven; The stock of oven dry is by going out baking oven under the baking oven bottom, right at last; Accomplish drying course, increased stock drying time widely, help improving the stock rate of drying.

This bilayer baking oven is provided with two kinds of blowing mouths, and a kind of is air knife formula blowing mouth 3, and as shown in Figure 3, tuyere is linear opening, and the eolian wire that this tuyere blows out distributes, and air quantity is more concentrated, mainly be installed on blow box (10,13) away from the charging and discharging mouth the position.Another kind is a mesh blowing mouth 6, and like Fig. 4, shown in Figure 5, its tuyere is uniform netted aperture setting, and the wind that this tuyere blows out distributes more even, softer, and it is installed near the bottom position of the blow box 10 the charging and discharging mouth.Through adopting the mesh tuyere, avoided stock just to print ink flow property and blown colored stock picture on surface greatly.

The wallpaper printing drying unit of the utility model has solved effectively that under the big situation of last China ink amount printed article can not dry in time, be incubated that the casing internal difference in temperature is big, be prone to blow the problem of colored printing in the drying course.
