The drying component 8 includes a partition box 802, a V-shaped frame 803, a heating blower 805, a drying box 806, a filter plate 807 and a valve plate 811. The partition box 802 is fixedly connected to one side of the drying box 3, the V-shaped frame 803 is fixedly connected to the partition box 802, the heating blower 805 is fixedly connected to the bottom plate 1, and two conduction rollers 2 are movably installed on the bottom plate 1. The drying box 3 and the spray pipe 4 are located between the conduction rollers 2. The feed pipe 6 is fixedly connected to the bottom plate 1 through a bracket 7, and several The nozzles 5, the drying component 8 also includes an air vent 801 and a No. 1 air vent pipe 804. The air vent 801 is opened on both sides of the drying box 3 and is located at the upper and lower positions of the drying box 3. The partition box 802 is fixedly connected to the heating blower 805 through the No. 1 air vent pipe 804. The air outlet of the heating blower 805 is connected to the No. 1 air vent pipe 804 to pass the hot air into the drying box 806. A V-shaped frame 803 is provided in the drying box 806. The V-shaped frame 803 is used to separate the hot air so that the hot air can easily enter the drying box 3 through the air vents 801 at the upper and lower positions of the drying box 3, and dry both sides of the PU leather from the upper and lower positions of the drying box 3. The air inlet of the heating blower 805 is connected to the wind box 814. By sucking gas from the wind box 814, a negative pressure is formed in the wind box 814, which is convenient for absorbing the gas in the drying box 3.

[0022] The drying box 806 is fixedly connected to the other side of the drying box 3, and two filter plates 807 are fixedly connected to the drying box 3. The valve plate 811 is movably installed on the drying box 3 and is located between the filter plates 807. The drying component 8 also includes a feed port 808 and a sealing plug 809. The feed port 808 is opened on the drying box 806, and the sealing plug 809 is movably installed in the feed port 808. The drying component 8 also includes a movable port 810 and a discharge port 812. The movable port 810 is opened at the side position of the drying box 806, the valve plate 811 is movably installed in the movable port 810, and the discharge port 812 is opened at the bottom surface of the drying box 806, and the discharge port 812 is located between the filter plates 807. The drying component 8 also includes a No. 2 ventilation pipe 813 and a bellows 814. The bellows 814 is fixedly connected to the bottom plate 1, and the air inlet of the bellows 814 is connected to the heating The blower 805 is fixedly connected, and the drying box 806 is fixedly connected to the bellows 814 through the No. 2 ventilation pipe 813. Negative pressure is generated in the bellows 814 to absorb the drying box 3, so that the hot air can easily enter the bellows 814 through the No. 2 ventilation pipe 813, so that the hot air can be reused. After the heating blower 805, the temperature is made higher, which is convenient for drying the workpiece. After the sealing plug 809 on the drying box 806 is pulled out, the desiccant is filled into the drying box 806 through the feed port 808. The desiccant is located between the filter plates 807 and above the valve plate 811, and the gas passing through the drying box 806 is dried. When the desiccant needs to be replaced, the valve plate 811 is pulled outward, so that the valve plate 811 can be easily removed from the movable port 810, and the desiccant can be easily discharged from the discharge port 812, making the replacement of the desiccant more convenient.

[0023] It should be noted that the present invention is a double-sided coating device with a drying structure. Both sides of the PU leather pass through the conduction roller 2 respectively. The PU leather also passes through two spray pipes 4 and the drying box 3. The feed pipe 6 is connected to the pipeline of the external spray slurry. The valve is opened to introduce the slurry into the feed pipe 6. The spray pipe 4 is located above and below the leather. The slurry is sprayed out through the nozzle 5 to spray both sides of the leather. Then the leather enters the drying box 3, and the heating blower 805 is started to send the hot air into the separation box 802 through the No. 1 ventilation pipe 804. After the hot air contacts the V-shaped frame 803, the hot air is separated and enters through the vents 801 at the upper and lower positions of the drying box 3 to dry the leather. As the drying proceeds, the water vapor in the drying box 3 increases, making the drying box 3 prone to moisture and heating. The hot air outlet of the blower 805 is interconnected with the No. 1 ventilation pipe 804, and the air inlet of the heating blower 805 is interconnected with the bellows 814. The gas in the bellows 814 is extracted and the air pressure is reduced. The bellows 814 absorbs the gas in the drying box 806 through the No. 2 ventilation pipe 813, and the drying box 806 absorbs the gas in the drying box 3 through the vent 801, and the hot air and water vapor are sucked into the drying box 806. Desiccant is filled between the filter plates 807, and the desiccant absorbs the water vapor in the hot air, so that the drying box 3 is easy to keep dry and the drying effect in the drying box 3 is improved. The dried gas enters the bellows 814 through the drying box 806. Since the gas contains a large amount of heat, it is reheated by the heating blower 805 and then discharged, so that the temperature of the hot air is higher, which can be better dried and effectively avoid heat waste.
