[0060] The implementation principle of the drying device for the inorganic fiber carrier in the embodiment of the application is as follows: the control system starts the guide motor 18 and the winding motor 42, the output shaft of the guide motor 18 drives the guide roller 17 to rotate, and the output shaft of the winding motor 42 drives the winding roller 3 to rotate through the speed reducer 41. By controlling the rotating speeds of the guide motor 18 and the winding motor 42, the tension of the inorganic fiber paper 0 in the conveying process is controlled, so as to facilitate the winding of the inorganic fiber paper 0 on the winding roller 3.

[0061] The control system starts the electric heating plate 92, the electric heating plate 92 generates heat and produces heat radiation, most of the heat radiation generated by the electric heating plate 92 acts on the inorganic fiber paper 0 under the action of the heat collecting plate 93, so that the inorganic fiber paper 0 is quickly dried, and the first temperature sensor 94 feeds back the temperature at the heat collecting plate 93 at any time, and the hot air at the heat collecting plate 93 flows to the second temperature sensor 109, and the second temperature sensor 109 feeds back the temperature value to the control system at any time.

[0062] At the same time, the control system starts the air pump 835, the air pump 835 draws the hot air near the second temperature sensor 109 in the drying box 7 to the drying box 831 through the backflow pipe 834, the hot air dried through the moisture absorption net plate 836 flows to the heat supply pipe 832 through the backflow pipe 833, the hot air in the heat supply pipe 832 flows to the two hot air boxes 81, and the air pressure in the hot air boxes 81 increases.

[0063] The hot air in the hot air boxes 81 is continuously blown to the inorganic fiber paper 0 through the hot air flow channel 82, so that the inorganic fiber paper 0 is preheated and achieves the effect of preliminary dehydration through air flow, and under the limiting action of the flow collecting inclined plate 12, the flow rate of the hot air flowing through the heat collecting plate 93 increases.

[0064] Therefore, the water vapor evaporated from the inorganic fiber paper 0 at the heat collecting plate 93 is quickly discharged, at the same time, the fast flowing air flow reduces the heat accumulation on the dried inorganic fiber paper 0, avoids the inorganic fiber paper 0 being over-dried, and part of the hot air flowing to the second temperature sensor 109 flows to the backflow pipe 834 again, so as to continuously circulate.

[0065] When the temperature feedback by the second temperature sensor 109 and the third temperature sensor 13 is high, the control system starts the temperature adjusting cylinder 105, the piston rod of the temperature adjusting cylinder 105 extends, the piston rod of the temperature adjusting cylinder 105 drives the adaptive rod 107 to push the linkage rod 108 to slide through the adjusting block 106, and the driving rod 104 rotates around the adjusting shaft 102.

[0066] At the same time, the adaptive rod 107 and the adjusting block 106 slide, so that the angle of the fan plate 103 is increased, the air vent 101 is opened, and the air outside flows into the drying box 7 through the air vent 101, so that the temperature at the second temperature sensor 109 is reduced, and the temperature of the air flowing into the hot air box 81 is reduced, so as to control the temperature of the preheating treatment of the inorganic fiber paper 0 in the hot air box 81, thereby avoiding the situation that the inorganic fiber paper 0 is rapidly dried.

[0067] The control system starts the shaping motor 114, the output shaft of the shaping motor 114 drives the shaping roller 112 to rotate, the shaping roller 112 drives the shaping belt 113 to rotate through friction, and the inorganic fiber paper 0 is pressed on the shaping belt 113 and is conveyed synchronously with the shaping belt 113 under the action of the pressing plate 115, in the process, the hot air flowing through the second temperature sensor 109 in the drying box 7 will shape the inorganic fiber paper 0, so as to improve the surface condition of the inorganic fiber paper 0.

[0068] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
