The area of air port, the hot-air mouth and cold wind mouth is identical, and the hot air chamber and cold air chamber are connected with the Dao Zhui types wind mixed chamber
Logical, wind mixed chamber's lower ending opening is simultaneously connected with the air inlet of dryer.
Further, the drive device includes the motor that rotating shaft and drive shaft are rotated, the rotating shaft with it is described cold and hot
Aerofoil is connected, and the motor is fixed on the side wall of the rectangular box.
Further, under original state, the cold wind plate of the cold and hot aerofoil closes cold wind mouthful, the hot-air mouth standard-sized sheet.
Further, under original state, the hot blast plate of the cold and hot aerofoil closes hot-air mouth, the cold wind mouthful standard-sized sheet.
Further, the side wall of the rectangular box is provided with two limit switches, and the limit switch is by the angle of the axis of rotation
Degree is limited in 90 degree.
Further, aperture pointer of the end of the rotating shaft provided with convenient observation cold-hot wind mixed proportion.
Further, temperature sensor is provided with the wind mixed chamber, the temperature controller can control institute with feedback signal
The rotation amplitude of motor is stated, and then controls the rotational angle of cold and hot aerofoil.
The beneficial effects of the invention are as follows：
1st, the present invention only needs a motor control, reduces cost, improves reliability；
2nd, rotated, preservation total blast volume is constant, while adjusting cold-hot wind intake ratio, do not influenceed by the cold and hot aerofoil of motor control
Drying effect, and reduce the difficulty of automatically controlled design；
3rd, the present invention is simple in construction, easy for installation.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of temperature control device for dryer as shown in Figure 1 to Figure 3, including rectangular box 1 and back taper wind mixed chamber
2, the rectangular box 1 is hot air chamber and cold air chamber by cold and hot 3 points of aerofoil, and the cold and hot aerofoil 3 is by orthogonal hot blast plate
Fix and form with cold wind plate, the rectangular box 1 is provided with the drive device for controlling cold and hot aerofoil 3 to rotate, the drive device
The motor 5 rotated including rotating shaft 4 and drive shaft 4, the rotating shaft 4 is connected with the cold and hot aerofoil 3, and the motor 5 is fixed on
On the side wall of the rectangular box 1.The hot air chamber and cold air chamber upper end are respectively equipped with hot-air mouth 6 and the connection of connection hot air source
The area of the cold wind in cold wind source mouthful 7, the hot-air mouth 6 and cold wind mouthfuls 7 is identical, the hot air chamber and cold air chamber with it is described fall vertebra
Type wind mixed chamber 2 is connected, and the lower ending opening of wind mixed chamber 2 is simultaneously connected with the air inlet of dryer.The side wall of the rectangular box 1
Provided with two limit switches 8, the angle that the rotating shaft 4 is rotated is limited in 90 degree by the limit switch 8.The rotating shaft 4
