[0022] Further improvement, such as Figure 3As shown, the processing table 2 includes a hollow column 16 and a top plate 17 installed on the top of the hollow column 16 . A floating opening 18 is opened in the middle of the top plate 17 , and the floating plate 13 is located in the floating opening 18 .

[0023] Further improvement, such as Figure 2 As shown, the driven air guide ring 8 includes a ring body 19 and a connecting ring 20 rotatably embedded in the outside of the ring body 19, two groups of air guide ports 21 are opened on the surface of the ring body 19 and an annular groove 22 is formed on the periphery, the heater 9 is installed in the air guide port 21, the connecting ring 20 is movably embedded in the annular groove 22 and the outer end is connected to the gas heating box 10 through a pipeline.

[0024] Further improvement, such as Figure 2 As shown, the heater 9 includes a hollow vertical plate 23, an arc-shaped air guide plate 24 and a nozzle 25. The hollow vertical plate 23 is connected to the ring body 19. The arc-shaped air guide plate 24 is fixed to the top of the hollow vertical plate 23. The nozzles 25 are divided into several groups and are evenly installed on the inner side of the arc-shaped air guide plate 24. The arc-shaped air guide plate 24 is located on the top plate 17. The air is guided through the hollow vertical plate 23 and introduced into the arc-shaped air guide plate 24, and the hot air flow is blown onto the printed parts through the nozzle 25 to achieve the purpose of heating and curing.

[0025] Further improvement, such as Figure 4 As shown, the gas heating box 10 includes a box body 26, a blower 27, an electric heating plate 28, a horizontal plate 29, a temperature sensor 30, a display screen 31 and a controller 32. The blower 27 is installed on one side of the box body 26 and the air outlet end faces the inside of the box body 26. The electric heating plates 28 are divided into several groups and are evenly arranged in the box body 26. The horizontal plate 29 is divided into two groups and is symmetrically installed at the ends of several groups of electric heating plates 28. An air outlet 33 is opened on the inner side of the box body 26. The temperature sensor 30 is installed in the air outlet 33 and is divided into two groups through the line. The blower 27 guides the airflow into the box body 26 and passes through the electric heating plate 28. The electric heating plate 28 is powered on to heat the introduced gas, which passes through the motor heating plate 28 and is heated. The heated gas is detected by the temperature sensor 30 and the temperature data is transmitted to the display screen 31. When the temperature is too high, a certain number of the electric heating plates 28 are closed through the controller 32. When the temperature is low, the corresponding number of the electric heating plates 28 are opened to increase the temperature of the passing gas, thereby achieving the purpose of dynamic regulation.

[0026] Further improvement, such as Figure 4As shown, the surface of the electric heating plate 28 has a porous structure, and several groups of electric heating plates 28 are connected in parallel through lines. The corresponding number of electric heating plates 28 can be turned on according to the heating needs. The power of the electric heating plate 28 close to the blower 27 is less than the power of the electric heating plate 28 far away from the blower 27, so as to achieve the purpose of gradually heating the passing gas.

[0027] Specifically, the driver 14 includes a collar 34, a floating rod 35, a servo motor 36 and a transmission gear 37. The collar 34 is located in the hollow column 16. The floating rod 35 is located in the collar 34 and has a plurality of blocks 38 formed on its surface. The servo motor 36 is mounted on the collar 34 and the power output end is connected to the transmission gear 37. The transmission gear 37 is meshed with the block 38. The transmission gear 37 is driven to rotate by the servo motor 36. During the rotation, the transmission gear 37 can act on the block 38 on the floating rod 35, thereby driving the floating rod 35 to float up and down and driving the floating plate 13 to adjust up and down.

[0028] When in use: the parts are printed on the floating plate 13 of the processing table 2 by the 3D printer 1. When heating and curing treatment is required during the printing process or after the printing is completed, the air flow is introduced into the box body 26 by the blower 27 and passes through the electric heating plate 28. The electric heating plate 28 is powered on to heat the introduced gas, which passes through the motor heating plate 28 and is heated. The heated gas is detected by the temperature sensor 30 and the temperature data is transmitted to the display screen 31. When the temperature is too high, a certain number of electric heating plates 28 are closed by the controller 32. When the temperature is low, a corresponding number of electric heating plates 28 are opened to increase the temperature of the passing gas, so as to achieve the purpose of dynamic regulation. The hot air flow is introduced into the connecting ring 20 through the pipeline, and the gas is introduced into the ring body 19 through the connecting ring 20 and is diverted, and then enters through the hollow vertical plate 23 The hot air is guided and introduced into the arc-shaped air guide plate 24, and the hot air flow is blown onto the printed parts through the nozzle 25 to achieve the purpose of heating and curing. At the same time, the driving motor 6 drives the driving gear 7 to rotate, and the driving gear 7 drives the ring body 19 to rotate during the rotation. The ring body 19 drives the heater 9 to rotate synchronously during the rotation and performs rotational dynamic heating and curing treatment on the printed parts. When it is necessary to cure some resin printed parts, the servo motor 36 can also drive the transmission gear 37 to rotate. The transmission gear 37 can act on the block 38 on the floating rod 35 during the rotation, thereby driving the floating rod 35 to float downward and driving the floating plate 13 to adjust downward, thereby sinking the resin printed parts into the shell 12, and exposing the printed parts to ultraviolet light to further cure the resin and increase the surface hardness.
