[0036] Please refer to Figures 1-5 The embodiments provided by the utility model have the advantages that the hot air drying device based on the coating equipment can realize hot air drying of the substrate, and the substrate can be dried in the hot air drying device.

[0037] A kind of discharging hot air drying device based on coating equipment, including hot air drying oven 1, feeding port 2 is set to the side wall of hot air drying oven 1 and is penetrated, and another side wall of hot air drying oven 1 is set to discharging port, substrate is entered to inside by the feeding port 2 of hot air drying oven 1 and is discharged after being dried substrate from discharging port after hot air drying.

[0038] Specifically, the inside of the hot air drying box 1 is provided with a conveying assembly 3, the conveying assembly 3 comprises a support frame 31, a cross plate 32, a first roller 33 and a second roller 34, the hot air drying box 1 is sleeved on the outside of the support frame 31, the two side walls of the support frame 31 are fixedly installed with the cross plate 32 through bolts, and the two ends of the first roller 33 and the second roller 34 are rotatably connected to the two side walls of the cross plate 32 through bearings.

[0039] The base material entering the hot air drying box 1 through the feeding port 2 slides on the first roller 33 and the second roller 34 respectively, so that the hot air drying treatment can be performed during the process of sliding from the first roller 33 to the second roller 34.

[0040] The side wall of the hot air drying box 1 is fixedly installed with a spacing adjusting assembly 4, the spacing adjusting assembly 4 comprises a motor 41, a fixing frame 42, a guide rail 43, a sliding groove 44, a first lead screw 45, a flange plate 46, a second lead screw 47, a sliding seat 48 and a mounting plate 49, the guide rail 43 is fixedly installed on the side wall of the hot air drying box 1, the guide rail 43 is provided with the sliding groove 44 inside, the bottom surface of the guide rail 43 is fixedly installed with the fixing frame 42, the bottom surface of the fixing frame 42 is fixedly installed with the motor 41, the ends of the first lead screw 45 and the second lead screw 47 are fixedly installed through the flange plate 46, the output shaft of the motor 41 is fixedly installed on the end of the first lead screw 45 away from the flange plate 46 through a shaft coupling, the first lead screw 45 and the second lead screw 47 are rotatably connected inside the sliding groove 44, the sliding seat 48 is provided with a threaded hole inside, the sliding seat 48 is threadedly connected with the side walls of the first lead screw 45 and the second lead screw 47 through the threaded hole inside, the side wall of the sliding seat 48 is fixedly installed with the mounting plate 49, and the inner side of the mounting plate 49 is fixedly installed with the blowing assembly 5 through bolts.

[0041] According to different base materials or different materials of the film coating, the required drying temperature is different, therefore, by controlling the spacing adjusting assembly 4, the blowing assembly 5 is driven to be close to or away from the base material, so that different base materials and film coating materials can be adjusted and treated.

[0042] The principle is:

[0043] The motor 41 drives the shaft coupling to rotate, so that the first lead screw 45 and the second lead screw 47 can rotate in the sliding groove 44, during the rotation, since the screw threads of the first lead screw 45 and the second lead screw 47 are opposite, the sliding seat 48 on the first lead screw 45 and the second lead screw 47 can move in opposite directions or in the same direction according to the different rotation directions of the motor 41, thereby driving the blowing assembly 5 to be close to or away from the base material to be dried, so as to adjust the temperature of the hot air drying for the base material, so as to adjust and treat different base materials and film coating materials.

[0044] Meanwhile, since the blowing assembly 5 blows hot air to dry the two surfaces of the substrate, the drying efficiency and effect can be effectively improved.

[0045] The blowing assembly 5 comprises a connecting plate 51, a mounting hole 52, a guide plate 53, an inner cavity 54, a heating mechanism, an air outlet 57, an air inlet 58, and an exhaust head 59. The two sides of the guide plate 53 are integrally formed with the connecting plate 51. The connecting plate 51 on one side of the guide plate 53 is fixedly connected to the inner side of the mounting plate 49 through the mounting hole 52 by means of a bolt. The top surface of the guide plate 53 is provided with the air inlet 58. The inner wall of the guide plate 53 is provided with the inner cavity 54. The heating mechanism is installed inside the inner cavity 54. The bottom surface of the guide plate 53 is provided with a plurality of air outlets 57. The plurality of air outlets 57 are fixedly installed with the exhaust head 59. The heating mechanism comprises a fixed seat 55 and a heating copper pipe 56. The two ends of the inner cavity 54 are fixedly installed with the fixed seat 55. The heating copper pipe 56 is installed inside the fixed seat 55.

[0046] The air flow is introduced into the inner cavity 54 through the air inlet 58 and the fan. After being heated by the heating copper pipe 56, the air flow becomes hot air. The hot air enters the exhaust head 59 through the plurality of air outlets 57. The two surfaces of the substrate are blown by the plurality of exhaust heads 59. The hot air acts on the surface of the substrate, so that the moisture on the surface of the substrate is evaporated into water vapor, thereby drying the surface of the substrate.

[0047] It is worth noting that the connecting plate 51 on the other side of the guide plate 53 is fixedly installed with a guide assembly 6. The guide assembly 6 comprises a fixed plate 61, a fixed rod 62, and a moving plate 63. The fixed plate 61 is welded to the top surface and the bottom surface of the fixed rod 62. The fixed plate 61 is fixedly installed on the side wall of the hot air drying box 1. One side wall of the moving plate 63 is fixedly connected to the side wall of the connecting plate 51. The inner part of the moving plate 63 is provided with a sliding hole. The moving plate 63 is slidably connected to the side wall of the fixed rod 62 through the sliding hole.

[0048] When the guide assembly moves relatively or oppositely under the adjustment of the spacing adjusting assembly 4, in order to ensure that the guide plate 53 in the guide assembly vertically rises or falls, the moving plate 63 is slid up and down on the fixed rod 62, so as to ensure the vertical movement of the guide assembly, thereby ensuring that the spacing from the surface of the substrate is the same, so as to prevent the temperature from being uneven due to different spacings.

[0049] The bottom side wall of the hot air drying box 1 is fixedly installed with a dehumidifying assembly 7. The dehumidifying assembly 7 comprises an exhaust fan 71, an exhaust cover 72, and a filter screen 73. The exhaust fan 71 is fixedly installed on the bottom side wall of the hot air drying box 1. The air inlet end of the exhaust fan 71 is fixedly installed with the exhaust cover 72. The exhaust port of the exhaust cover 72 is installed with the filter screen 73.

[0050] After the moisture on the substrate evaporates into water vapor, it stays in the hot air drying box 1. In order to quickly exhaust the water vapor in the hot air drying box 1, the exhaust fan 71 is operated, and the water vapor in the hot air drying box 1 is timely exhausted through the exhaust hood 72, so as to prevent the dried substrate from being affected by excessive water vapor and causing poor drying effect.

[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
