[0003] Traditional drying methods typically rely on external heating, such as heating and drying through hot air convection. However, this method has some significant disadvantages. For example, external heating requires heat to be transferred through air convection, which results in a long heat transfer path and low efficiency. In addition, due to the uneven flow of hot air and the limitations of internal heat transfer in the powder coating, it is easy to cause some areas to overheat while other parts remain undried.

[0016] Through the above technical solution, the setting of the reinforcement plate and support feet enhances the overall stability of the device, ensures that the equipment is not prone to tipping or vibration during operation, and improves the service life of the equipment. The reinforcement plate can provide additional protection for the storage cylinder, preventing damage to the storage cylinder due to external force impact and other reasons, thereby increasing the reliability of the equipment.

[0017] As a further improvement of the above solution, the inner thread of the tapered discharge hole is connected with a blocking block.

[0018] Through the above technical solution, the threaded block can conveniently control the opening and closing of the conical discharge hole, thereby realizing the control of material discharge, ensuring that the material is discharged at the right time, and improving production efficiency.

[0028] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5The present embodiment provides a uniform drying device for the production of thermosetting powder coatings, comprising a storage cylinder 1, an inner wall of which is provided with a heat-insulating layer 2, an upper surface of which is clamped with a top cover 3, a lower surface of which is provided with an assembly groove 4, and an inner wall of which is fixedly connected with an electric heating wire group 5. First, the heating wire group 5 is installed in the assembly groove 4 on the lower surface of the top cover 3. This allows the heating wire group 5 to directly heat the powder coating in the storage barrel 1. The heating wire group 5 is designed to evenly distribute heat, which means that heat is evenly transferred throughout the interior space of the storage barrel 1. This uniform heat distribution helps to avoid local overheating or uneven heating, thereby ensuring that the powder coating can achieve a consistent drying effect. The inner wall of the storage barrel 1 is provided with an insulation layer 2. This design is intended to reduce heat loss through the outer wall of the storage barrel 1. The function of the insulation layer 2 is to maintain the temperature inside the storage barrel 1 and prevent heat loss. This can maintain a stable drying environment and further improve drying efficiency. At the same time, by reducing heat loss, energy conservation is also achieved. Due to the even distribution of heat generated by the heating wire group 5 and the effective insulation effect of the insulation layer 2, the entire drying process is more efficient. In this environment, the powder coating can be quickly and evenly heated to the required temperature to complete the curing process.

[0031] The inner wall of the assembly trough 4 is fixed with a frame 6 by bolts, and the internal rotation of the frame 6 is connected to the blowing fan body 7. The upper surface of the top cover 3 is provided with an air inlet 8 for the blowing fan body 7 to intake air. When the blowing fan body 7 is started, it begins to rotate and generate airflow. The external air is sucked into the system through the air inlet 8 on the top cover 3. The airflow generated by the blowing fan body 7 forms forced convection inside the storage cylinder 1. Inside the storage cylinder 1, the heating wire group 5 generates heat and heats the surrounding air. Due to the action of the blowing fan body 7, the heated air is forced to move, forming a hot air circulation. The circulating flow of hot air ensures that the temperature distribution inside the storage cylinder 1 is more uniform. In this way, no matter where inside the storage cylinder 1, it can be heated to the same degree, thereby improving the uniformity and efficiency of the drying process.

[0032] Auxiliary handles 9 are fixedly connected to both sides of the upper surface of the top cover 3, and a motor base 10 is fixedly connected to the middle of the upper surface of the top cover 3. The setting of the auxiliary handles 9 allows the operator to open and close the top cover 3 more conveniently, thereby adding or removing materials, thereby improving the convenience of operation.

[0033] A servo motor 11 is provided inside the motor base 10, and the output end of the servo motor 11 is fixedly connected to the transmission shaft 12. The servo motor 11 can provide precise speed and position control and can adjust the speed of the blower fan body 7 as needed, thereby achieving precise control of the air flow and wind speed during the drying process.

[0034] A stirring cross bar 13 is fixedly connected to the outer surface of the transmission shaft 12, and a conical discharge hole 14 is opened on the inner bottom wall of the storage cylinder 1. The transmission shaft 12 rotates under the drive of the motor, driving the stirring cross bar 13 to evenly stir the powder coating in the storage cylinder 1, ensuring that the material is fully in contact with the hot air, improving the drying effect, and the design of the conical discharge hole 14 can effectively prevent the material from being blocked during the discharge process, ensuring that the material can be discharged smoothly. The shape of the conical discharge hole 14 makes it easier for the material to slide down under the action of gravity, thereby improving the discharge efficiency and reducing the discharge time.

[0035] A reinforcement plate 15 is sleeved on the outer surface of the storage cylinder 1, and support feet 16 are fixedly connected to the four corners of the lower surface of the reinforcement plate 15. The arrangement of the reinforcement plate 15 and the support feet 16 enhances the overall stability of the device, ensures that the equipment is not prone to tipping or vibration during operation, and improves the service life of the equipment. The reinforcement plate 15 can provide additional protection for the storage cylinder 1, preventing the storage cylinder 1 from being damaged due to external force impact and other reasons, thereby increasing the reliability of the equipment.

[0036] The internal thread of the conical discharge hole 14 is connected with a block 17. The threaded block 17 can conveniently control the opening and closing of the conical discharge hole 14, thereby realizing the control of material discharge, ensuring that the material is discharged at the appropriate time, and improving production efficiency. The threaded block 17 can fit tightly with the conical discharge hole 14 to prevent material leakage during storage and ensure the effective utilization of the material.

[0037] The implementation principle of a uniform drying device for thermosetting powder coating production in the embodiment of the present application is as follows: a person first removes the top cover 3 through the auxiliary handle 9, and then puts the powder coating into the interior of the storage cylinder 1. At this time, the heating wire group 5 can directly heat the powder coating in the storage cylinder 1. The heating wire group 5 is designed to distribute heat evenly, which means that heat is evenly transferred in the entire internal space of the storage cylinder 1. This uniform heat distribution helps to avoid local overheating or uneven heating, thereby ensuring that the powder coating can obtain a consistent drying effect. An insulation layer 2 is provided on the inner wall of the storage cylinder 1. This design is intended to reduce heat loss to the outside through the outer wall of the storage cylinder 1. The function of the insulation layer 2 is to maintain the temperature inside the storage cylinder 1 and prevent heat loss. This can maintain a stable drying environment and further improve the drying efficiency. At the same time, by reducing heat loss, the purpose of saving energy is also achieved. 5 The heat generated is evenly distributed, and the effective insulation effect of the insulation layer 2 makes the entire drying process more efficient. The powder coating can be quickly and evenly heated to the required temperature in such an environment to complete the curing process. The heating wire group 5 generates heat and heats the surrounding air. Due to the action of the blowing fan body 7, the heated air is forced to move, forming a hot air cycle. The circulating flow of hot air ensures that the temperature distribution inside the storage cylinder 1 is more uniform. Finally, the personnel starts the servo motor 11, and the transmission shaft 12 rotates under the drive of the motor, driving the stirring cross bar 13 to evenly stir the powder coating in the storage cylinder 1, ensuring that the material is in full contact with the hot air and improving the drying effect. The design of the tapered discharge hole 14 can effectively prevent the material from being blocked during the discharge process, ensuring that the material can be discharged smoothly. The shape of the tapered discharge hole 14 makes it easier for the material to slide down under the action of gravity, thereby improving the discharge efficiency and reducing the discharge time.

Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
