Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a dehumidifying dryer for PETG plastic granules. Background Technology

[0002] PETG plastic granules are a thermoplastic environmentally friendly plastic. They have excellent transparency and high gloss, as well as good impact resistance, heat resistance, chemical resistance and yellowing resistance. PETG plastic granules have excellent processing performance and can be molded using conventional plastic processing methods, such as extrusion, injection molding, blow molding, thermoforming and calendering.

[0003] After production, existing PETG plastic granules require drying using a dryer. Current dryers typically involve pouring the PETG granules into a drum, blowing hot air into it, and then stirring the granules to dry them. However, because the drum is relatively enclosed, the moisture on the PETG granules is difficult to separate. Even if moisture does detach, it tends to settle at the bottom or in the corners of the drum, where it re-adheres during the stirring process, reducing the drying efficiency. Utility Model Content

Detailed Implementation

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0042] like Figures 1-4 As shown, this embodiment proposes a dehumidifying dryer for PETG plastic granules, including a cylinder 1 with a feed inlet and a feed pipe 21 fixedly connected thereto. The cylinder 1 has numerous drainage holes on its circumferential surface. It also includes a frame 2, a moving plate 3, a rotating mechanism, an air outlet mechanism, and a tilting mechanism. Two sliding rods 16 are fixedly connected to the moving plate 3, and each sliding rod 16 is fixedly connected to a sliding ring 17. Two moving rods 22 are fixedly connected inside the frame 2, and the two sliding rings 17 are slidably connected to the two moving rods 22 respectively. The cylinder 1 is rotatably connected to the frame 2. Both ends of the two moving rods 22 are fixedly connected to the fixing plates 18. Multiple fixing plates 18 are fixedly connected to the frame 2. The moving plate 3 is slidably connected to the frame 2. Through the cooperation between the frame 2, the moving plate 3, the rotating mechanism, the air outlet mechanism and the flipping mechanism, it is easy to throw off the moisture on the PETG plastic granules when the cylinder 1 rotates, and blow hot air into the cylinder 1, so that the PETG plastic granules are evenly dried. Moisture is not easy to remain in the cylinder 1, which improves the drying efficiency of PETG plastic granules.

[0043] The rotating mechanism is mounted on the frame 2 and is used to drive the cylinder 1 to rotate. The rotating mechanism includes a rotating frame 4, rotating plates 5, and a driving assembly. Two support plates 20 are fixedly connected to the rotating frame 4, and a fixed frame 7 is fixedly connected to the top of the two support plates 20. Two rotating rings 19 are fixedly connected to the rotating frame 4, and two rotating plates 5 are rotatably connected within the two rotating rings 19. The rotating frame 4 is rotatably connected within the frame 2. Two rotating plates 5 are provided, and both are rotatably connected within the rotating frame 4. The cylinder 1 is fixedly connected to one side opposite to the two rotating plates 5. The driving assembly is mounted on the rotating frame 4. The drive assembly for rotating the rotating plate 5 and the cylinder 1 includes a gear ring 6, a fixed frame 7, a drive gear 8, and a first motor 9. The gear ring 6 is fixedly connected to one of the rotating plates 5, the fixed frame 7 is fixedly connected to the rotating frame 4, the drive gear 8 meshes with the gear ring 6, and the first motor 9 is mounted on the fixed frame 7. The output end of the first motor 9 is fixedly connected to the drive gear 8. Specifically, the first motor 9 drives the drive gear 8 and the gear ring 6 to rotate. When the gear ring 6 rotates, it drives the rotating plate 5 and the cylinder 1 to rotate, thereby causing the PETG plastic granules to tumble inside the cylinder 1 and throwing water out of the cylinder 1.

[0044] The air outlet mechanism is installed on the movable plate 3 and is used to air dry PETG plastic granules. The air outlet mechanism includes: air box 10, fan 11 and heating tube 12. The air box 10 is fixedly connected to the top of the movable plate 3. There are two fans 11, both of which are installed on the movable plate 3. The output ends of the two fans 11 are facing the cylinder 1. There are multiple heating tubes 12, all of which are installed inside the air box 10. Specifically, the fan 11 blows air into the cylinder 1, and the heating tube 12 heats the air blown out by the fan 11, thereby air drying the PETG plastic granules inside the cylinder 1.

[0045] The tilting mechanism is located inside the frame 2 and is used to drive the cylinder 1 to tilt the PETG plastic granules. The tilting mechanism includes a tilting gear 13, a power gear 14, and a second motor 15. The tilting gear 13 is fixedly connected to the rotating frame 4, and the power gear 14 is rotatably connected inside the frame 2. The power gear 14 meshes with the tilting gear 13. The second motor 15 is mounted on the frame 2, and its output end passes through the frame 2 and is fixedly connected to the power gear 14. Specifically, after the PETG plastic granules are dried, the second motor 15 drives the power gear 14 and the tilting gear 13 to rotate, thereby driving the rotating frame 4 and the cylinder 1 to rotate, thus tilting the feed inlet downwards and allowing the dried PETG plastic granules to be poured out.

[0046] In this embodiment, when PETG plastic granules need to be dried, the PETG plastic granules are added into the cylinder 1 through the feed inlet. Then, the first motor 9 is started, which drives the drive gear 8 and the gear ring 6 to rotate. When the gear ring 6 rotates, it drives the rotating plate 5 and the cylinder 1 to rotate, so that the PETG plastic granules tumble inside the cylinder 1 and throw the water out of the cylinder 1. During this process, the fan 11 blows air into the cylinder 1, and the air blown out by the fan 11 is heated by the heating pipe 12, thereby drying the PETG plastic granules inside the cylinder 1. After the PETG plastic granules are dried, the second motor 15 drives the power gear 14 and the tilting gear 13 to rotate, thereby driving the rotating frame 4 and the cylinder 1 to rotate, so that the feed inlet is tilted downwards, and the dried PETG plastic granules can be poured out.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
