Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a temperature regulating device for the preparation of indium tin oxide, including an insulated outer cylinder 1 and an inner cylinder 2 connected inside the insulated outer cylinder 1. A heating chamber 26 is provided between the inner cylinder 2 and the insulated outer cylinder 1. A spiral tube 24 is wound around the outer wall of the inner cylinder 2. A flow regulating body 1 7 and a flow regulating body 2 10 are connected to the outside of the insulated outer cylinder 1. The flow regulating body 1 7 is connected to the heating chamber 26, and the flow regulating body 2 10 is connected to the spiral tube 24. The flow regulating body 2 10 is connected to a regulating mechanism for regulating the flow of cold and hot air. The regulating mechanism includes an regulating plate 13, a screw 17, a second motor 20, and a rotating head 21. The regulating plate 13 is slidably connected to the flow regulating body 1 7 and the flow regulating body 2 10. A gas delivery channel 23 is provided inside the flow regulating body 1 7 and the flow regulating body 2 10. The opening size of the corresponding gas delivery channel 23 is adjusted by the regulating plate 13 to facilitate the control of the air intake and keep the internal temperature of the inner cylinder 2 within a suitable range, which is convenient for the processing of materials. Motor 20 is used to drive screw 17 to rotate, screw 17 is used to drive adjustment plate 13 to reciprocate, rotating head 21 is used to guide screw 17, and rotating head 21 is connected to a positioning mechanism for positioning screw 17.

[0024] The inner cylinder 2 is provided with a feed inlet 3 at the top and a discharge pipe 4 at the bottom. The material is fed into the inner cylinder 2 through the feed inlet 3. The flow regulating body 7 is connected to a hot air pipe 8, which is connected to a hot air blower. The hot air blower is existing technology and can inject hot air into the heating chamber 26 through the flow regulating body 7 to make the inner cylinder 2 heat up evenly.

[0025] The flow regulator 2 10 is connected to a cold air pipe 9, which is connected to a cold air generator. The cold air generator is existing technology. It delivers cold air to the spiral tube 24 through the flow regulator 2 10, so that the inner cylinder 2 is cooled evenly. Finally, the cold air is discharged from the exhaust pipe 11 at the end of the spiral tube 24. The exhaust pipe 11 is connected to the input end of the cold air generator to realize gas circulation operation.

[0026] The regulating mechanism also includes a threaded plate 19 and a guide seat 16. The end of the threaded plate 19 is fixedly connected to the regulating plate 13, and the screw 17 passes through the threaded plate 19. The guide seat 16 is connected to the bottom of the flow regulating body 7, and the rotating head 21 is rotatably connected to the guide seat 16. The motor 20 can drive the screw 17 to rotate, thereby driving the threaded plate 19 and the regulating plate 13 to move back and forth, facilitating the adjustment of the position of the regulating plate 13, and thus realizing the adjustment of the opening size of the two air delivery channels 23, which facilitates the control of the air intake.

[0027] The rotation of screw 17 can drive the rotating head 21 to rotate. The rotating head 21 slides relative to the guide seat 16, which plays a good guiding role for screw 17 and improves the stability of screw 17 rotation.

[0028] The screw 17 is threadedly connected to the threaded plate 19, the power output end of the motor 20 is connected to the screw 17, and the motor 20 is fixed to the bottom of the flow regulating body 20.

[0029] The positioning mechanism includes a cylinder 14 and a positioning head 15. The cylinder 14 is connected to the bottom of the flow regulating body 7, and the power output end of the cylinder 14 is connected to the positioning head 15. When the internal temperature of the inner cylinder 2 is within a suitable range, the cylinder 14 drives the positioning head 15 to move forward, so that the positioning head 15 connects with the positioning groove 22 in the rotating head 21, thereby limiting the rotation head 21 and locking the screw 17, which facilitates the limiting and fixing of the adjusting plate 13.

[0030] The rotating head 21 is provided with a positioning groove 22, which matches the positioning head 15. The positioning groove 22 is a toothed groove. When the positioning head 15 is connected to the positioning groove 22, the positioning head 15 can be well limited and fixed.

[0031] A motor 5 is connected to the top of the inner cylinder 2, and a stirrer 27 is connected to the power output end of the motor 5. The stirrer 27 is located inside the inner cylinder 2. The motor 5 drives the stirrer 27 to rotate, and the rotation of the stirrer 27 makes the material mix evenly, thereby improving the uniformity of the material heating.

[0032] A temperature sensor 25 is connected to the inner wall of the inner cylinder 2, and a mounting base 6 is connected to the side of the insulated outer cylinder 1. A PLC controller is connected to the top of the mounting base 6. The PLC controller is electrically connected to the temperature sensor 25, the cylinder 14, and the second motor 20. Flow regulator 7 and flow regulator 10 are fixed to the bottom of the mounting base 6. The temperature sensor 25 can detect the internal temperature of the inner cylinder 2 and feed the detection information back to the PLC controller. The PLC controller controls the operation of the second motor 20, which facilitates the adjustment of the position of the regulating plate 13, and in turn, the adjustment of the opening size of the two air supply channels 23, facilitating the control of the air intake. This ensures that the inside of the inner cylinder 2 is at a suitable processing temperature, achieving automated operation and saving time and labor.

[0033] The bottom of the heat-insulating outer cylinder 1 is provided with a pressure relief hole 12, which is connected to the heating chamber 26. The pressure relief hole 12 is connected to a one-way valve. When the gas pressure in the heating chamber 26 reaches a certain value, the one-way valve can discharge the internal gas to achieve the purpose of pressure relief.

[0034] Working Principle: Material is injected into the inner cylinder 2 through the feed inlet 3. Motor 5 drives the agitator 27 to rotate, causing the agitator 27 to stir the material and ensure uniform heating. Temperature sensor 25 detects the internal temperature of the inner cylinder 2 and feeds the information back to the PLC controller, which controls the operation of motor 20. Motor 20 drives screw 17 to rotate, which in turn drives threaded plate 19 and adjusting plate 13 to move back and forth. Adjusting plate 13 adjusts the opening size of the two air supply channels 23, facilitating the control of the air intake. This regulates the amount of cold air entering the spiral tube 24 and the amount of hot air entering the heating chamber 26, keeping the internal temperature of the inner cylinder 2 within a suitable range for material processing. Once the internal temperature of the inner cylinder 2 is within a suitable range, cylinder 14 drives positioning head 15 forward, connecting it to the positioning groove 22 in guide seat 16. This locks screw 17 in place and improves the stability of the connection between adjusting plate 13 and flow regulator 7 and flow regulator 10.
