DETAILED DESCRIPTION

[0022] The technical scheme of the utility model is described below in conjunction with the drawings in the specification. Figures 1-5 , through specific embodiment, explain the technical scheme of the utility model.

[0023] Embodiment:

[0024] As Figures 1-4 shown, the utility model provides a line ink high efficiency drying machine, including fixed frame 1, the bottom of fixed frame 1 is vertically fixed and is installed with a plurality of support legs 5, and the middle part of fixed frame 1 is fixedly installed with first drying box 2, and the top of first drying box 2 is fixedly installed with conveying line 3, and the top of conveying line 3 is fixedly installed with second drying box 4, and first drying box 2 and second drying box 4 are all located in the middle part of conveying line 3, and first drying box 2 is communicated with second drying box 4, and the top of both sides of fixed frame 1 is fixedly installed with support frame 6, and support frame 6 is fixedly installed at the bottom of both ends of conveying line 3, and the bottom of first drying box 2 and the top of second drying box 4 are all fixedly installed with a plurality of evenly distributed fans 7, and the output end of fan 7 is all located in first drying box 2 and second drying box 4, and the top of both sides of second drying box 4 is fixedly installed with jacking cylinder 8, and the output end of jacking cylinder 8 is all fixedly installed with box door assembly 9, and box door assembly 9 is movably connected with both sides of second drying box 4.

[0025] A plurality of evenly distributed electric heating wires 10 are fixedly installed in first drying box 2, and a plurality of evenly distributed infrared heating tubes 11 are fixedly installed in second drying box 4.

[0026] Feed inlet 41 and discharge outlet 42 are respectively formed in the left and right sides of second drying box 4, and box door assembly 9 located at both sides of second drying box 4 is movably connected with feed inlet 41 and discharge outlet 42 respectively, and guide chute 43 is fixedly installed on both sides of feed inlet 41 and discharge outlet 42, and box door assembly 9 is slidably connected with guide chute 43.

[0027] As Figure 5As shown, the door assembly 9 includes a door panel 91 that is movably connected to the second drying chamber 4. A mounting plate 92 is fixedly installed on the surface of the door panel 91 away from the second drying chamber 4. Pulleys 93 are fixedly installed on both sides of the mounting plate 92. The pulleys 93 are slidably connected in the guide groove 43. A connecting rod 94 is vertically fixedly installed on the top of the mounting plate 92. A top plate 95 is fixedly installed on the top of the connecting rod 94. The output end of the lifting cylinder 8 is fixedly installed at the bottom of the top plate 95.

[0028] Working steps: First, lower the door assemblies 9 on both sides of the second drying chamber 4 so that they align with the inlet 41 and outlet 42 respectively. Activate the heating wire 10 and infrared heating tube 11. The heating wire 10 heats the air inside the first drying chamber 2 and the second drying chamber 4. After heating, start the fan 7 on the first drying chamber 2 and the second drying chamber 4 to circulate the air heated by the heating wire 10, forming a convective airflow. Place the PCB boards with printed ink onto the rack, and then place the rack on the end of the conveyor line 3 located at the inlet 41. Activate the lifting cylinder 8 on the side of the inlet 41. The output end of the lifting cylinder 8 lifts, causing the door assembly 9 to separate from the inlet 41. The conveyor line 3 starts, slowly moving the rack containing the PCB boards into the second drying chamber 4. After all the PCBs have entered the second drying chamber 4, the lifting cylinder 8 on the side of the inlet 41 is activated again, causing the door assembly 9 to reset and close the inlet 41. The infrared heating tube 11 dries the ink printed on the PCB board on the rack. The convective airflow in the first drying chamber 2 and the second drying chamber 4 comes into contact with the PCB board and dries the ink. When the rack moves to the outlet 42 side, the lifting cylinder 8 on the outlet 42 side is activated, causing the door assembly 9 on the outlet 42 side to rise, so that the rack containing the PCB board can move from the outlet 42 position to the outside of the second drying chamber 4. After the rack has completely moved to the outside of the second drying chamber 4, the lifting cylinder 8 on the outlet 42 side is activated again, causing the door assembly 9 on the outlet 42 side to reset, completing the drying of the circuit ink. Production can then continue, and the above steps can be repeated.

[0029] Note: There are multiple methods for controlling the opening and closing of the door assembly 9 at the inlet 41 and outlet 42, and the control methods are relatively mature, so they will not be described in detail here.

[0030] Working principle: The heating wire 10 inside the first drying chamber 2 heats the air inside both the first and second drying chambers 4, creating a high-temperature environment. The conveyor line 3 transports the PCB board with printed ink. The ink is baked in this high-temperature environment, accelerating its curing. The infrared heating tube 11 inside the second drying chamber 4 activates, generating infrared rays that directly dry the PCB board with printed ink, further accelerating curing. Infrared heating uses thermal radiation, and the ink curing process proceeds from the inside out. High-temperature baking, on the other hand, directly contacts the ink surface, and the curing process proceeds from the outside in. The combination of these two methods... The ink surface and interior are simultaneously cured towards the middle layer of the ink to improve the drying efficiency and ensure drying quality. Fans 7 are installed on both the first drying chamber 2 and the second drying chamber 4. The fans 7 drive the airflow in the first drying chamber 2 and the second drying chamber 4 to generate convection. The hot airflow contacts the ink more fully and evenly, further improving the drying quality. By installing chamber door assemblies 9 on both the inlet 41 and the outlet 42, the chamber door assemblies 9 can block the inlet 41 and the outlet 42, effectively intercepting the hot air in the second drying chamber 4, reducing the heat loss in the first drying chamber 2 and the second drying chamber 4, reducing energy consumption, and improving the practicality of the device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
