In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] like Figures 1 to 3As shown, the utility model discloses a plastic sheet drying device for plastic recycling processing, comprising a frame 1 and a drying drum 2, the drying drum 2 is used to dry the plastic sheets, a feeding seat 3 is provided at one end of the drying drum 2, the end of the drying drum 2 is rotatably connected to the feeding seat 3, a feeding hopper 31 is provided on the feeding seat 3, a climbing conveyor belt 4 is provided on the frame 1, a water filter hole 41 is provided on the climbing conveyor belt 4, the water filter hole 41 is multiple and spaced apart from each other, the climbing conveyor belt 4 is used to send the plastic sheets to the feeding hopper 31, a paving mechanism is provided on the frame 1, the paving mechanism is used to spread the plastic sheets flatly so as to filter out the moisture carried by the plastic sheets, by arranging the climbing conveyor belt 4, In addition, a water filter hole 41 is provided on the climbing conveyor belt 4. When the plastic sheets need to be dried, the plastic sheets can be conveyed to the feed hopper 31 through the climbing conveyor belt 4 to reduce the labor intensity of manual feeding. In the process of conveying, due to the setting of the water filter hole 41, the moisture carried by the plastic sheets can be filtered out from the water filter hole 41 during the conveying process, so as to facilitate the drying of the plastic sheets by the drying drum 2, thereby improving the overall drying efficiency of the plastic sheets. In addition, through the provided flattening mechanism, the plastic sheets can be moved during the conveying process of the plastic sheets, so that the plastic sheets can be flattened and dispersed, thereby ensuring that the water of the plastic sheets as a whole is more fully filtered.

[0020] In this embodiment, the specific structure of the paving mechanism includes a rotating rod 51, the end of the rotating rod 51 is rotatably connected to the inner side of the frame 1, and a toggle plate 52 is fixed to the outer periphery of the rotating rod 51. There are multiple toggle plates 52 and they are evenly distributed around the circumference. The toggle plates 52 are located above the climbing conveyor belt 4. A driving motor 53 is provided on the outer side of the frame 1. The driving motor 53 is used to drive the rotating rod 51 to rotate. In the process of the climbing conveyor belt 4 conveying the plastic sheets to the feeding hopper, the rotating rod 51 is driven to rotate by starting the driving motor 53, so that the toggle rod can be driven to toggle the stacked plastic sheets, so as to flatten the plastic sheets and disperse them.

[0021] In this embodiment, the end of the drying cylinder 2 is rotatably connected to the feeding seat 3, so as to prevent the feeding hopper 31 from rotating with the rotation of the drying cylinder 2, so as to ensure that the climbing conveyor belt 4 can continuously feed the plastic sheets through the feeding hopper 31, so as to improve the overall drying efficiency of the plastic sheets. Its specific structure is that an annular slide rail 6 is provided on the inner periphery of the feeding seat 3, and an annular bracket 7 is fixedly mounted on the end of the drying cylinder 2, and the annular bracket 7 is rotatably connected to a pulley 8, and the pulley 8 is coupled to the slide rail and forms a sliding fit between the two. Therefore, after the drying cylinder 2 rotates, the pulley 8 can also rotate along the annular slide rail 6, so as to ensure that the climbing conveyor belt 4 can continuously feed the plastic sheets through the feeding hopper 31, while not affecting the rotation of the drying cylinder 2;

[0022] It should be noted that the drying drum 2 used in this embodiment is the existing technology, that is, the drying drum 2 is rotated so that the plastic sheets entering the drying drum 2 can form a material curtain, thereby increasing the contact area between the plastic sheets and the air, thereby achieving the drying of the plastic sheets, and a steam connecting pipe 32 is provided on the feed seat 3, which is connected to an external steam generator through the steam connecting pipe 32, so that the generated steam can be delivered into the drying drum 2 through the steam connecting pipe 32, thereby further improving the drying efficiency of the plastic sheets.

[0023] In this embodiment, a guide plate 9 is further provided in the feed seat 3, one end of the guide plate 9 is fixed to the inner wall of the feed seat 3, and the other end extends toward the inside of the drying cylinder 2. The height of the guide plate 9 gradually decreases along the direction toward the inside of the drying cylinder 2 and forms an inclined guide side wall. The set guide plate 9 can guide the plastic sheets put into the feed hopper 31 into the drying cylinder 2, so as to avoid the plastic sheets being retained in the feed seat 3 and affecting the drying of the plastic sheets.

[0024] In this embodiment, a feeding plate 10 is provided at one end of the climbing conveyor belt 4 facing the feed hopper 31. The feeding plate 10 is located below the climbing conveyor belt 4. One end of the feeding plate 10 is fixed to the frame 1, and the other end extends toward the feed hopper 31. The height of the feeding plate 10 decreases gradually along the direction toward the feed hopper 31 and forms an inclined feeding side wall. Through the setting of the feeding plate 10, the plastic sheets conveyed by the climbing conveyor belt 4 can be guided into the feed hopper 31 to ensure the stability of the climbing conveyor belt 4 in feeding the plastic sheets into the feed hopper.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
