[0060] Wherein, the fixing block 6 is slidably connected with the supporting groove 7;

[0061] Wherein, the mounting block 9 is arranged in the drying chamber 1;

[0071] Wherein, the second motor 16 is fixedly connected to the bottom wall of the fixing groove 15;

[0072] The rotating shaft 17 is fixedly connected to the rotating output shaft of the second motor 16 .

[0073] Further, the upper end of the rotating shaft 17 extends out of the upper surface of the mounting block 9;

[0080] Furthermore, in this solution, the product enters the drying chamber 1 along the connecting groove 2 for heating and drying. When the pump is started, the pump passes the air in the drying chamber 1 and the positioning box 3 through the output end of the air pump and the hose 20, and outputs gas through the nozzle 12. The gas will be sprayed on the product. This process also causes the air in the drying chamber 1 to circulate. At this time, the air outside the drying chamber 1 will also enter the drying chamber 1 through the connecting groove 2.

[0081] Furthermore, in this solution, the air pressure output by the air pump is relatively low and will not cause damage to the product;

[0082] As mentioned above, when the first motor 4 is started, the first motor 4 starts to drive the threaded rod 5 to rotate, thereby driving the fixing block 6 and the mounting block 9 to move forward and backward, thereby synchronously driving the nozzle 12 to move forward and backward to spray air into the drying chamber 1, so that the air circulation in the drying chamber 1 is better, thereby having a better drying effect on the product, thereby increasing the efficiency of three-dimensional digital printing, thereby increasing the practicality of the equipment;

[0083] As mentioned above, when the second motor 16 is started, the second motor 16 starts to drive the rotating shaft 17 to rotate, and then synchronously drives the first sliding rod 18 to move the second sliding rod 19, so that the second sliding rod 19 rotates around the rotating tube 11. In this process, the clockwork 14 is tightened, and then the rotating tube 11 and the nozzle 12 are synchronously driven to rotate, so that the spray angle of the nozzle 12 is tilted, and it is no longer vertically downward. When the first sliding rod 18 rotates to no longer contact the second sliding rod 19, at this time, under the action of the release elastic force of the clockwork 14, the nozzle 12 is driven to restore the vertical downward state, and then the second motor 16 drives the nozzle 12 to swing around the rotating tube 11 for each rotation, so that the air circulation is more intense and the air convection is better, thereby improving the drying effect on the product, increasing the efficiency of three-dimensional digital printing, and thereby increasing the practicality of the equipment.

[0084] Furthermore, in the present solution, both the first motor 4 and the second motor 16 are high temperature resistant motors, that is, the motors can work normally at high temperatures.

[0085] Working principle: When the device is used, the product enters the drying chamber 1 along the connecting groove 2 for heating and drying. When the pump is started, the pump passes the air in the drying chamber 1 and the positioning box 3 through the output end of the air pump and the hose 20, and outputs gas through the nozzle 12. The gas will be sprayed on the product. This process also causes the air in the drying chamber 1 to circulate. At this time, the air outside the drying chamber 1 will also enter the drying chamber 1 through the connecting groove 2;

[0086] As mentioned above, when the first motor 4 is started, the first motor 4 starts to drive the threaded rod 5 to rotate, thereby driving the fixing block 6 and the mounting block 9 to move forward and backward, thereby synchronously driving the nozzle 12 to move forward and backward to spray air into the drying chamber 1, so that the air circulation in the drying chamber 1 is better, thereby having a better drying effect on the product, thereby increasing the efficiency of three-dimensional digital printing, thereby increasing the practicality of the equipment;

[0087] As mentioned above, when the second motor 16 is started, the second motor 16 starts to drive the rotating shaft 17 to rotate, and then synchronously drives the first sliding rod 18 to move the second sliding rod 19, so that the second sliding rod 19 rotates around the rotating tube 11. In this process, the clockwork 14 is tightened, and then the rotating tube 11 and the nozzle 12 are synchronously driven to rotate, so that the spray angle of the nozzle 12 is tilted, and it is no longer vertically downward. When the first sliding rod 18 rotates to no longer contact the second sliding rod 19, at this time, under the action of the release elastic force of the clockwork 14, the nozzle 12 is driven to restore the vertical downward state, and then the second motor 16 drives the nozzle 12 to swing around the rotating tube 11 for each rotation, so that the air circulation is more intense and the air convection is better, thereby improving the drying effect on the product, increasing the efficiency of three-dimensional digital printing, and thereby increasing the practicality of the equipment.

[0088] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
