Abstract
The utility model relates to the print machinery, in particular to a hot-blast circulation device for horizontal paper-feeding hot-blast drying device. The hot-blast circulation device is mainly used for drying printed-matters after screen printing. The hot-blast circulation device for horizontal paper-feeding hot-blast drying device comprises an upper box body and a lower box body. A fan and an electrothermal tube are arranged in the lower box body. The air outlet of the fan is connected with one side of the bottom of the upper box body. The bottom of the upper box body is provided with uncountable small ventilating ducts. The utility model is characterized in that the front of the air inlet of the fan is fixedly mounted with an electrothermal tube; a motor used to drive a centrifugal fan is simultaneously heat insulated and cooled. The temperature of hot air blown out by the utility model is uniform, and thus the drying speed and the drying quality for the printed-matters are improved.
Description
(1) technical field
The utility model relates to printing machinery, relates in particular to flat paper feeding air flow dryer heated air circulation device.This heated air circulation device is mainly used in the drying of printing after the serigraphy.
(2) background technology
Existing flat paper feeding air flow dryer heated air circulation device, comprise upper box and lower box, dress centrifugal blower and electrothermal tube in the lower box, electrothermal tube is after being placed in the centrifugal blower air outlet, the wind that blower fan blows out blows to the passage input upper box that links to each other with upper box bottom one side with the heat of electrothermal tube, the upper box bottom has countless airing holes road, and hot blast sprays to the foraminous conveyer between upper box and lower box again from little duct, the printing on the guipure is carried out drying.But uneven in temperature from the hot blast after electrothermal tube heating that fan outlet blows out, influence the rate of drying and the dry mass of printing.
(3) summary of the invention
The utility model has overcome that the hot blast that existing blower fan blows out is uneven in temperature, the rate of drying that influences printing and the defective of dry mass, and a kind of new flat paper feeding air flow dryer heated air circulation device is provided.This heated air circulation device adopts electrothermal tube is placed in the centrifugal blower air inlet, and after cold and hot air mixed through centrifugal blower, the hot blast temperature that blows out was even, thereby has improved the rate of drying and the dry mass of printing.
The utility model is achieved in that a kind of flat paper feeding air flow dryer heated air circulation device, comprise upper box and lower box, dress blower fan and electrothermal tube in the lower box, fan outlet links to each other with upper box bottom one side, the upper box bottom has countless airing holes road, it is characterized in that being installed with electrothermal tube before the air inlet.
Above-mentioned flat paper feeding air flow dryer heated air circulation device, the motor of described driving blower fan is surrounded by thermal insulation layer, and ventilation shaft is equipped with in the thermal insulation layer upper and lower, and the leg space ventilation pipeline is connected to the lower box outside, before the overdraught pipeline is connected to air inlet.
Above-mentioned flat paper feeding air flow dryer heated air circulation device, described blower fan is a centrifugal blower.
The utility model is that electrothermal tube is placed in the centrifugal blower air inlet, and after cold and hot air mixed through centrifugal blower, the hot blast temperature that blows out was even, thereby has improved the rate of drying and the dry mass of printing.Carry out heat insulation to the motor that drives centrifugal blower simultaneously and cooling, the thermal insulation layer upper and lower surface is equipped with ventilation shaft, and upper and lower two ventilation shafts connect air inlet and lower box outside respectively.Because the air inlet air pressure of blower fan less than the pressure of casing outside, is forming cross-ventilation in the thermal insulation layer around the blower motor, the heat in the thermal insulation layer is taken away by flow air like this, thereby has realized the cooling to motor.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the air outlet channel design schematic diagram of centrifugal blower;
Fig. 4 is the left view of Fig. 3;
Fig. 5 be among Fig. 4 A to view.
Among the figure: 1 upper box, 2 little ducts, 3 foraminous conveyers, 4 lower boxes, 5 electrothermal tubes, 6 centrifugal blower air inlets, 7 centrifugal blowers, 8 leg space ventilation pipelines, 9 overdraught pipelines, 10 thermal insulation layers, 11 air outlet passages,
(5) specific embodiment
Referring to Fig. 1, Fig. 2, a kind of flat paper feeding air flow dryer heated air circulation device comprises upper box 1 and lower box 4, dress blower fan 7 and electrothermal tube 5 are installed with electrothermal tube 5, in the present embodiment in the lower box 4 before the air inlet 6, blower fan 7 is a centrifugal blower, and electrothermal tube 5 is two groups.Centrifugal blower 7 air outlets link to each other with upper box 1 bottom one side through air outlet passage 11.Referring to Fig. 3, Fig. 4, Fig. 5,11 outlets of air outlet passage have four mouths side by side, make hot blast can evenly import upper box 1.Upper box 1 bottom has countless airing holes road 2.The printing that hot blast is ejected on the foraminous conveyer 3 that is loaded on 1,4 of upper and lower casings from aperture road 2 is carried out drying, and foraminous conveyer 3 is passed by with certain speed.Lower box 4 absorbs the hot blast under upper box 1 injection, and heating is after centrifugal blower 7 is transported in the upper box 1 again, and so continuous circulation is carried out.The hot blast temperature that centrifugal blower 7 blows out is even, thereby has improved the rate of drying and the dry mass of printing.
In flat paper feeding air flow dryer heated air circulation device, the motor cooling that drives centrifugal blower 7 is vital.The cooling of motor is that employing is heat insulation and air-cooled, and motor is surrounded by thermal insulation layer 10, and ventilation shaft 9,8 is equipped with in thermal insulation layer 10 upper and lowers, and leg space ventilation pipeline 8 is connected to lower box 4 outsides, before overdraught pipeline 9 is connected to centrifugal blower air inlet 6.Because the air pressure of centrifugal blower air inlet 6 less than the pressure of casing 4,1 outside, is forming cross-ventilation in the thermal insulation layer 10 around centrifugal blower 7 motors, the heat in the thermal insulation layer 10 is taken away by flow air like this, thereby has realized the cooling to motor.
Heated air circulation device of the present utility model can be realized the bone dry to printed matter by several groups of series connection.
