[0017] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0018] like Figure 1 This is a schematic structural diagram of the utility model, a drying device for a wavy color-coated plate coating, comprising a housing 1 and a transmission mechanism 2, the transmission mechanism 2 being used to transmit the color-coated plate, the transmission mechanism 2 being arranged on the housing 1, and the output end and the input end of the transmission mechanism 2 both protrude from the housing 1, and the transmission mechanism 2 being a chain plate transmission belt;

[0019] The transmission mechanism 2 divides the internal space of the shell 1 into a drying chamber 11 and a heat source chamber 12. A heat source mechanism 3 is arranged in the heat source chamber 12. The heat source mechanism 3 includes a hot air blower 31, an upper partition 32 and two side partitions 33. The upper partition 32 and the two side partitions 33 are fixedly connected to the shell 1, and the partition is located in the heat source chamber 12. The partition and the shell 1 enclose a heat equalization chamber 13. The hot air blower 31 is composed of three major parts: a blower, a heater, and a control circuit. The output end of the hot air blower 31 is connected to the heat equalization chamber 13. A through hole 321 is opened on the upper partition 32. The through hole 321 is used to connect the heat equalization chamber 13 and the drying chamber 11. A self-opening and closing component 4 is arranged in the through hole 321. The self-opening and closing component 4 is used to make the hot air generated by the hot air blower 31 remain in the heat equalization chamber 13.

[0020] like Figure 2 、 Figure 3 As shown, the self-opening and closing component 4 includes a sealing plate 41, a locking block 42 and a reset element 43. The reset element 43 is a spring. The sealing plate 41 and the upper partition 32 are rotatably connected. A receiving groove 322 is provided on the upper partition 32, and the receiving groove 322 is connected to the through hole 321. The locking block 42 is located in the receiving groove 322, and the locking block 42 and the receiving groove 322 are slidingly connected. One end of the reset element 43 abuts the locking block 42, and the other end abuts the receiving groove 322. The locking block 42 is located above the sealing plate 41, and the locking block 42 can contact the locking block 42. The locking block 42 has an introduction surface 421 that expands outward from top to bottom to avoid the sealing plate 41 from getting stuck.

[0021] When the hot air blower 31 injects hot air into the heat-saturating chamber 13, the internal pressure increases, causing the sealing plate 41 to press against the locking block 42, so that the hot air is retained in the heat-saturating chamber 13 for a period of time.

[0022] When the hot air blower 31 continues to inject hot air into the heat-saturating chamber 13 until the pressure in the heat-saturating chamber 13 exceeds the elastic force of the reset element 43, the locking block 42 retracts into the accommodating groove 322, and the sealing plate 41 rotates to connect the heat-saturating chamber 13 and the drying chamber 11. The pressure in the heat-saturating chamber 13 drops, the locking block 42 is reset, and the sealing plate 41 flips over and presses against the locking block 42 again.

[0023] like Figure 2 As shown, an L-shaped guide plate 5 is arranged in the heat equalizing chamber 13. The guide plate 5 is arranged at the inlet of the heat equalizing chamber 13, and the bent portion of the guide plate 5 extends downward to below the inlet of the heat equalizing chamber 13, so that the heat flow undergoes an upward flow process again, making the temperature distribution uniform and avoiding the input hot air from directly flowing upward and accumulating above the heat equalizing chamber 13.

[0024] like Figure 2 As shown, a mixed flow impeller 6 is arranged in the heat equalizing chamber 13, the mixed flow impeller 6 is rotatably connected to the housing 1, and the mixed flow impeller 6 is located between the guide plate 5 and the inlet of the heat equalizing chamber 13, so as to further mix the hot air evenly.

[0025] like Figure 2 As shown, a drainage hood 7 is arranged on the upper partition 32, the drainage hood 7 surrounds the through hole 321, and the drainage hood 7 is located outside the heat equalization chamber 13. The drainage hood 7 is used to draw the hot air to the drying chamber 11. The drainage hood 7 has a guiding function to reduce heat loss.

[0026] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
