[0002] Coater drying refers to heating and drying the coated material during the coating process to improve product quality and extend service life; the temperature and time of the coater drying should be adjusted according to different materials and technical requirements to ensure the drying effect of the material. Generally speaking, the higher the temperature, the shorter the drying time, but it is easy to cause surface overheating and affect the quality of the material; conversely, when the temperature is low, the drying time is longer, but the protective effect on the material is stronger. In addition, it is necessary to select appropriate drying methods and methods (such as normal temperature, high temperature or vacuum, etc.) according to the properties of different materials and process requirements to meet production needs.

[0023] Specifically, the end of the air intake pipe 1 away from the vacuum pump 9 passes through the right side of the inner top wall of the mounting frame 5 near the front end and the top of the waste heat recovery box 2 and extends to the interior of the waste heat recovery box 2. The connection between the air intake pipe 1 and the placement frame and the waste heat recovery box 2 is fixed.

[0024] In this embodiment, it is convenient to extract the heat inside the waste heat recovery box 2.

[0025] Specifically, the end of the air outlet insulation pipe 4 away from the vacuum pump 9 passes through the left side of the inner top wall of the mounting frame 5 near the front end and the top of the preheating box 8 and extends to the interior of the preheating box 8. The connection between the air outlet insulation pipe 4 and the placement frame and the preheating box 8 is fixed.

[0026] In this embodiment, the preheated airflow that is conveniently extracted enters the interior of the preheating box 8 through the air outlet insulation pipe 4.

[0027] Specifically, multiple pipe fixing frames 10 are evenly distributed on the outer surfaces of the air inlet pipe 1 and the air outlet insulation pipe 4, and the connection points between the outer surface of the air inlet pipe 1 and the placement plate 7 and the waste heat recovery box 2 are connected through the pipe fixing frames 10; the connection points between the outer surface of the air outlet insulation pipe 4 and the placement plate 7 and the preheating box 8 are connected through the pipe fixing frames 10.

[0028] In this embodiment, the stability of the air inlet pipe 1 and the air outlet insulation pipe 4 is enhanced.

[0029] Specifically, a feed end and a discharge port are provided on the left and right sides of the waste heat recovery box 2 and the preheating box 8, and coating material rollers are provided inside the waste heat recovery box 2 and the preheating box 8.

[0030] In this embodiment, it is convenient to transport materials.

[0032] In this embodiment, it is convenient to subsequently detect the humidity on the surface of the dried material.

[0033] Specifically, the end of the screw rod 16 away from the forward and reverse motor 17 passes through the rear end of the first mounting seat 13 and is fixedly installed with a ball bearing. The ball bearing at the end of the screw rod 16 away from the forward and reverse motor 17 is fixedly connected to the rear end of the bearing seat 12, and the front end of the first mounting seat 13 near the left and right sides is fixedly connected to the rear ends of the two sliding rods 14 respectively.

[0034] In this embodiment, the two ends of the slide rod 14 are fixed, thereby enhancing the stability of the slide platform 15 during movement and the load-bearing capacity of the slide platform 15 .

When the slide 15 moves and swings, it drives the humidity sensor 20 to swing together, so as to measure the moisture on the surface of the dried material. The material is tested and once the surface moisture of the dried material is too high, the buzzer inside the control box 6 is electrically driven to remind the staff to deal with it; the material after humidity detection and drying enters the waste heat recovery box 2, so that the waste heat on the material is extracted by the vacuum pump 9 and flows into the preheating box 8 through the air outlet insulation pipe 4, so as to preheat the material just to be dried, and avoid excessive moisture in the material directly entering the drying device body 3 to cause shrinkage and deformation; and when the preheated paper enters the drying device body 3 for drying, it can also reduce some drying time, help improve work efficiency, and reduce waste of resources; the dried material enters the waste heat recovery box 2 and flows out from the discharge port of the waste heat recovery box 2, and then enters the coating machine dust collector 21, and the surface of the material is dusted, and then flows into the next process after dust removal.
