[0024] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3 As shown, the present embodiment is a rapid drying device for a coated substrate, comprising a drying box 1, wherein the front and rear ends of the drying box 1 are provided with a material passing hole 2 for the substrate to pass through; an air outlet box 3 is installed on the inner wall of the drying box 1, and the tail end of the air outlet box 3 is connected to a ventilation pipe 4, and a plurality of heating pipes 31 are arranged in the air outlet box 3; a main exhaust pipe 6 and a side exhaust pipe 7 are arranged at the top of the drying box 1, and the side exhaust pipe 7 is used to connect the drying box 1 and the main exhaust pipe 6, and a water-absorbing sponge 8 is arranged in the main exhaust pipe 6, and a squeezer is arranged beside the water-absorbing sponge 8; a water storage tank 9 is arranged at the lower side of the main exhaust pipe 6, and the bottom end of the water storage tank 9 is connected to the air outlet box 3; specifically, during drying, the coated substrate is discharged from the drying box 3 by the air outlet box 3; The material hole 2 of the drying box 1 moves in and out, and the ventilation pipe 4 continuously inputs air into the air outlet box 3. The hot air heated by the heating pipe 31 is blown on the substrate for drying. The excess air carries water vapor from the side exhaust pipe 7 on the top and enters the main exhaust pipe 6. The water-absorbing sponge 8 absorbs the water vapor in the exhaust gas, and after a period of time, the squeezer squeezes the water-absorbing sponge 8 to flow into the water storage tank 9 for storage. When the humidity in the drying box 1 decreases, the valve of the connecting pipe between the water storage tank 9 and the air outlet box 3 is opened to allow part of the water to flow into the air outlet box 3. The heater heats the liquid water and vaporizes it again to enter the drying box 1 to adjust the humidity, thereby achieving the purpose of improving the drying environment and recycling the water vapor in the exhaust gas.

[0025] like Figure 1As shown, in this embodiment, an outlet pipe 61 is provided on the side of the main exhaust pipe 6, and an extrusion plate 10 is provided in the outlet pipe 61, and one end of the extrusion plate 10 is connected to a cylinder 11; the position of the extrusion plate 10 corresponds to the water-absorbing sponge 8 in the vertical direction; specifically, a supporting wire mesh that can hold the water-absorbing sponge 8 is provided in the main exhaust pipe 6, and the wire mesh is air-permeable and water-permeable. When the drying box 1 is in operation, the cylinder 11 is periodically expanded and contracted, and the extrusion plate 10 cooperates with the inner wall of the main exhaust pipe 6 to compress the water-absorbing sponge 8, so that a part of the liquid water flows into the water storage tank 9 under the action of gravity for standby use.

[0026] like Figure 1 and Figure 3 As shown, in order to increase drying efficiency and drying action surface, at least two air outlet boxes 3 are provided on the inner wall of one side of the drying box 1, and the air outlet boxes 3 are respectively located on the upper and lower sides of the feeding hole 2; specifically, during drying, the hot air discharged from the air outlet boxes 3 can be blown to both the upper surface and the lower surface of the substrate, and both sides are heated and cured at the same time.

[0027] In order to increase the area of ​​the substrate covered by the air, the air outlet of the air outlet box 3 is tilted toward the feeding hole 2; the air outlet boxes 3 are provided on the inner walls of both sides of the drying box 1.

[0028] Reference Figure 1 As shown, multiple ventilation pipes 4 are connected to an air supply pipe 13, an exhaust pump 14 is provided on the air supply pipe 13, and a dust removal filter 15 is provided at the front end of the air supply pipe 13; specifically, the drying box 1 provides a dust-free environment, and during the exhaust process of the exhaust pump 14, the air is first filtered by the dust removal filter 15, and then the air is distributed by the air supply pipe 13 to the ventilation pipes 4 on both sides of the drying box 1 for use.

[0029] Reference Figure 3 As shown, this embodiment also includes a preheating roller 5, two preheating rollers 5 are provided and arranged in parallel, and the preheating rollers 5 are arranged at the front end of the drying box 1; specifically, in order to slow down the curing time of the coating, the substrate is preheated by the preheating roller 5 before coating, so that the substrate has a certain temperature.

[0030] like Figure 1 As shown, the present embodiment further includes a humidity sensor 12, which is disposed on the top of the drying box 1; specifically, the humidity sensor 12 is used to monitor the humidity in the drying box 1 in real time, so as to control whether the water storage tank 9 needs to replenish water to the air outlet box 3 to increase the humidity; when the humidity is too high, the wind speed is increased to a certain extent to speed up the flow or the temperature of the heating tube 31 is increased accordingly.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
