[0002] A coating machine, also known as an extrusion casting laminating machine, is a modern packaging equipment mainly used to coat a thin film onto the surface of flexible substrates such as paper, plastic, metal, non-woven fabric, and woven fabric to achieve purposes such as moisture-proofing, waterproofing, corrosion prevention, oxidation prevention, and enhancing the strength and functional properties of the substrate.

[0003] In the prior art, a search revealed a Chinese patent disclosure entitled "A Plastic Particle Feeding Device for a Coating Machine," application number "202122030438.2." This patent mainly includes a storage hopper, a feeding device body, and a coating machine. While this utility model adds a hot air chamber and uses an air duct to deliver hot air from inside the hot air chamber to the inside of the storage hopper to dry the material inside and prevent moisture buildup and sticking due to environmental factors, the aforementioned storage hopper requires feeding through an inlet. The height of the storage hopper and the position of the inlet make manual feeding impossible, resulting in an inconvenient feeding method that still requires a feeding mechanism, increasing the complexity of the device structure and operating costs. Therefore, this utility model provides a plastic particle feeding device for a coating machine to solve the problems mentioned in the background art. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses a plastic granule feeding device for a coating machine, which includes a coating machine 1 and a feeding hopper located on the top of the coating machine 1. A mixing cylinder 2 is fixedly connected to the top of the coating machine 1 and above the feeding hopper. A feeding component is provided on one side of the opening of the mixing cylinder 2. The feeding component includes a feeding rack 3 fixedly connected to one side of the coating machine 1 and having a hollow internal structure, a feeding box 4 slidably connected inside the feeding rack 3, a feeding port 5 located on one side of the feeding rack 3 and near the bottom, a discharging port 6 located on the side of the feeding rack 3 near the opening of the mixing cylinder 2, and a control component for driving the feeding box 4 to move up and down. The side of the feeding box 4 near the mixing cylinder 2 has an open structure, and a first guide plate 7 extending into the interior of the mixing cylinder 2 is fixedly connected to the inside of the discharging port 6.

[0025] During feeding, the feeding box 4 is located at the bottom of the feeding frame 3, and plastic granules can be introduced into the feeding box 4 through the inlet 5. When the movable feeding box 4 moves upward, the open side cooperates with the feeding frame 3 to form a closed structure, thereby lifting the plastic granules to the mixing drum 2 through the moving feeding box 4. When the feeding box 4 moves to the outlet 6, the plastic granules are guided into the mixing drum 2 by the first guide plate 7, thus completing the feeding work. This achieves a highly efficient and automated feeding process, improving production efficiency.

[0026] The control components include a winch 10 fixedly connected to the top of the feeding rack 3, a connecting plate 8 fixedly connected to the top of the feeding box 4, and a sling 9 fixedly connected to the top of the connecting plate 8. The top end of the sling 9 is connected to the winch 10.

[0027] The lifting and lowering of the feeding box 4 can be easily controlled by the operation of the winch 10, thereby realizing the automatic feeding of plastic granules. The structure is simple and the feeding operation is highly efficient.

[0028] A rotating shaft 15 is rotatably connected inside the mixing cylinder 2. A stirring blade 16 is fixedly connected to one end of the rotating shaft 15 inside the mixing cylinder 2. A motor 14 is fixedly connected to the outside of the mixing cylinder 2. The rotating shaft 15 is fixedly connected to the output shaft of the motor 14. The mixing cylinder 2 is tilted and has a discharge port 17 at its bottom, located above the feeding hopper. This cleaning arrangement of the mixing cylinder 2 facilitates more complete feeding of the internal plastic granules. An openable cover plate 18 is provided inside the discharge port 17. A support plate 13 is fixedly connected to the bottom of the cover plate 18. Two electric push rods 12 are symmetrically installed at the bottom of the support plate 13, and both electric push rods 12 are fixedly connected to the top of the coating machine 1.

[0029] When the plastic granules are conveyed into the mixing drum 2, the motor 14 starts, and the rotating shaft 15 and the stirring blade 16 rotate together to fully stir and mix the plastic granules in the mixing drum 2, which can meet the mixing needs when feeding different types of plastic granules. Furthermore, stirring the plastic granules prevents them from sticking together. After stirring is complete, the electric push rod 12 drives the support plate 13 and its top cover plate 18 to move downwards, opening the discharge port 17 to convey the plastic granules into the coating machine 1.

[0030] A second guide plate 11 is fixedly connected inside the feed inlet 5. The second guide plate 11 is inclined downwards towards the inside of the feed rack 3 to facilitate the smooth introduction of plastic granules into the feed box 4. The bottom of the first guide plate 7 has a slope structure that slopes inwards towards the inside of the mixing cylinder 2, and the bottom of the feed box 4 has a slope structure that slopes towards the outlet 6 to ensure that the plastic granules inside the feed box 4 can smoothly slide into the mixing cylinder 2.

[0031] Working principle: During feeding, the feeding box 4 is located at the bottom of the feeding frame 3. Plastic granules can be poured into the feeding box 4 through the inlet 5. When the movable feeding box 4 moves upward, the open side cooperates with the feeding frame 3 to form a closed structure, thereby lifting the plastic granules to the mixing drum 2 through the moving feeding box 4. When the feeding box 4 moves to the outlet 6, the plastic granules are guided into the mixing drum 2 by the first guide plate 7, thus completing the feeding process.

[0032] When the plastic granules are conveyed into the mixing drum 2, the motor 14 starts, and the rotating shaft 15 and the stirring blade 16 rotate together to fully stir and mix the plastic granules in the mixing drum 2, which can meet the mixing needs when feeding different types of plastic granules. Furthermore, stirring the plastic granules prevents them from sticking together. After stirring is complete, the electric push rod 12 drives the support plate 13 and its top cover plate 18 to move downwards, opening the discharge port 17 to convey the plastic granules into the coating machine 1. This achieves a highly efficient and automated feeding process, improving production efficiency.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
