Description

Technical Field

[0001] This utility model relates to the field of coating machine drying oven technology, and in particular to a coating machine drying oven. Background Technology

[0002] The drying oven is an important component of the coating machine's drying system. The drying principle involves hot air jets from nozzles impacting the coating layer. The airflow transfers heat to the coating, and the solvent in the coating evaporates and is carried away by the airflow, achieving the drying purpose. In existing ovens, the heating system is located outside the oven, requiring independent support and connection to the oven via ductwork. This results in increased airflow resistance and pressure loss due to vibrations during hot air delivery. Furthermore, existing ovens are generally quite large. Utility Model Content

[0003] (I) Technical Issues

[0004] The purpose of this utility model is to provide a coating machine oven that solves the problem that the oven has a large overall volume and that the hot air delivery is subject to vibration and air intake resistance when a heating system is set up outside the oven.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coating machine oven includes an upper shell and a lower shell rotatably connected. A cylinder is rotatably mounted on the lower shell at intervals, and the telescopic rod of the cylinder is rotatably mounted on the upper shell. An inner liner and several nozzles are integrated inside the upper shell. A combustion furnace and an air inlet pipe are installed on the top of the upper shell. The air inlet end of the air inlet pipe is connected to the combustion furnace via an air blower, and the air outlet end of the air inlet pipe is connected to the inner liner. A return air pipe is provided on the upper shell, connecting to the air inlet end of the combustion furnace, and a cold air inlet is provided on the return air pipe.

[0008] Preferably, a U-shaped exhaust pipe communicating with the interior is installed at the bottom of the lower housing, and an exhaust fan is connected to the U-shaped exhaust pipe.

[0009] Preferably, the top of the upper housing is provided with an explosion-proof opening.

[0010] Preferably, a plurality of locking rods are rotatably mounted on the lower housing, and a locking block for locking the locking rods is provided on the upper housing.

[0011] Preferably, the air inlet pipe includes a conical section connecting the combustion furnace and the air inlet fan, the diameter of which gradually decreases from the combustion furnace side to the air inlet fan side.

[0012] Preferably, the air inlet pipe includes a U-shaped buffer section and a guide section connected to the buffer section. The air inlet end of the buffer section is connected to the air inlet fan, and the air outlet end of the guide section is connected to the upper casing.

[0013] (III) Beneficial Effects

[0014] By integrating the combustion furnace, air inlet fan, air inlet pipe, and inner liner onto the upper shell, the heating system is integrated into the oven, effectively reducing the overall volume and floor space of the oven. At the same time, the upper shell rotates relative to the lower shell to form a clamshell structure, and the upper shell is opened or closed relative to the lower shell by the action of a cylinder, which facilitates access to the interior for maintenance of the inner liner and nozzles.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] See Figures 1-4As shown in the embodiment of this utility model, a coating machine drying oven is proposed for integration into a coating machine to dry the coated film. Specifically, it includes an upper shell 1 and a lower shell 2 rotatably connected. A cylinder 3 is rotatably mounted on the lower shell 2 at intervals. The telescopic rod of the cylinder 3 is rotatably mounted on the upper shell 1. The extension and retraction of the cylinder 3 opens or closes the upper shell 1 relative to the lower shell 2, thereby avoiding manual disassembly of the upper shell 1 and facilitating access to the interior for assembly or maintenance of internal components after opening the upper shell 1. Meanwhile, an inner liner 4 and several nozzles 5 are integrated inside the upper shell 1. A combustion furnace 6 and an air inlet pipe 7 are installed on the top of the upper shell 1. The combustion furnace 6 is an internally integrated electric heater that heats the air flowing through it when energized. The air inlet end of the air inlet pipe 7 is connected to the combustion furnace 6 through an air blower 12, and the air outlet end of the air inlet pipe 7 is connected to the inner liner 4. A return air pipe 8 connected to the air inlet end of the combustion furnace 6 is provided on the upper shell 1, and a cold air inlet 9 is provided on the return air pipe 8. By integrating the combustion furnace 6 and the air inlet pipe 7 on the upper shell 1, the floor area of ​​the entire oven is reduced, the length of the air inlet pipe 7 is reduced, and swaying is avoided. The hot air from the combustion furnace 6 enters directly from the top of the inner liner 4 through the air inlet pipe 7 and is evenly distributed before flowing from the nozzles 5 to the film. This also avoids noise caused by vibration during the airflow process.

[0023] Meanwhile, the return air duct 8 is used to return some of the hot air to the combustion furnace 6 for further heating, and enters the external air through the cold air inlet 9 to regulate the internal heat, so as to control the internal baking temperature within the required range and fully improve the internal heat efficiency.

[0024] Meanwhile, a U-shaped exhaust pipe 10 communicating with the interior is installed at the bottom of the lower casing 2. An exhaust fan 11 is connected to the U-shaped exhaust pipe 10. The U-shaped exhaust pipe 10 mainly discharges the internal solvents and other substances from the bottom outwards, thereby reducing the concentration of the internal solvents.

[0025] Meanwhile, an explosion-proof vent 13 is provided on the top of the upper housing 1 to facilitate the venting of air when the internal pressure is too high.

[0026] Specifically, multiple locking rods 14 are rotatably mounted on the lower housing 2, and the upper housing 1 is provided with locking blocks 15 for locking the locking rods 14. After the upper housing 1 is closed relative to the lower housing 2, the locking rods 14 are rotated to cooperate with the locking blocks 15 and lock the locking rods 14, thereby ensuring a stable connection between the upper housing 1 and the lower housing 2 under double locking and a sealing effect at the interface.

[0027] Specifically, the air inlet pipe 7 includes a conical pipe section 70 connecting the combustion furnace 6 and the air inlet fan 12. The diameter of the conical pipe section 70 gradually decreases from the side of the combustion furnace 6 to the side of the air inlet fan 12. The gradually decreasing diameter allows the hot air in the combustion furnace 6 to flow faster towards the side of the air inlet fan 12, and under the action of the air inlet fan 12, a negative pressure is formed to accelerate the flow of hot air on the side of the combustion furnace 6.

[0028] Meanwhile, the air inlet pipe 7 includes a U-shaped buffer section 71 and a guide section 72 connected to the buffer section 71. The air inlet end of the buffer section 71 is connected to the air inlet fan 12, and the air outlet end of the guide section 72 is connected to the upper casing 1. The buffer section 71 buffers the fast-flowing air to avoid noise. Moreover, the buffered hot air can flow smoothly from the guide section 72 to the inner liner 4, making the airflow rate in the inner liner 4 more uniform and reducing the risk of impact.
