[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] like Figure 1-3As shown, this utility model provides a raw material mixing device for biodegradable plastic blown film, including a support frame 1, a mixing drum 2, a feeding hopper 3, a lifting mechanism 4, and a mixing rod 5. The mixing drum 2 and the feeding hopper 3 are installed on the support frame 1. The lower end of the mixing drum 2 is the feeding end and extends into the feeding hopper 3. The feeding hopper 3 is used to pour various plastic raw materials into the feeding hopper 3. The lifting mechanism 4 is rotatably installed in the mixing drum 2, and its lower end extends out of the mixing drum 2 to lift the raw materials in the feeding hopper 3 into the mixing drum 2. The mixing rod 5 is evenly installed on the side wall of the lifting mechanism 4 to mix the raw materials in the mixing drum 2 evenly. When using this device, various plastic raw material granules that need to be mixed are added to the feeding hopper 3. The lifting mechanism 4 lifts the raw materials in the feeding hopper 3 into the mixing drum 2, where they are mixed evenly by the stirring rod 5. This utility model automatically lifts the raw materials in the feeding hopper 3 into the mixing drum 2 for mixing through the lifting mechanism 4. It only requires adding various raw materials to the feeding hopper 3, eliminating the need to add materials from a high place from the top of the mixing drum 2. This makes the raw material mixing and feeding operation simple and quick, saves manpower, and improves the efficiency of raw material mixing.

[0017] The lifting mechanism 4 includes a rotating shaft 401 and a spiral blade 402. The rotating shaft 401 is vertically installed in the mixing drum 2. Its upper end is rotatably connected to a fixed plate 403 at the top of the mixing drum 2 via a bearing, and its lower end extends from the lower end of the mixing drum 2 and is rotatably connected to the bottom of the feed hopper 3. The stirring rod 5 is evenly connected to the side wall of the rotating shaft 401. The spiral blade 402 is located at the lower part of the rotating shaft 401, and a feed hopper 201 is provided at the lower end of the mixing drum 2. The spiral blade 402 is located in the feed hopper 201, with its lower end extending out of the feed hopper 201 and contacting the raw material in the feed hopper 3. The rotation of the stirring shaft drives the spiral blade 402 to rotate, and the spiral blade 402 lifts the raw material in the feed hopper 3 upward through the feed hopper 201 into the mixing drum 2. The rotating shaft 401 drives the stirring rod 5 to rotate and stir the raw material.

[0018] The mixing drum 2 is equipped with an inner drum 6, which is connected to the lower feed end of the mixing drum 2. Plastic raw materials are lifted into the inner drum 6 from the feed end. The upper end of the inner drum 6 is provided with a discharge notch 601, which is connected to the upper end of a discharge pipe 7 installed between the inner drum 6 and the inner wall of the mixing drum 2. The lower end of the discharge pipe 7 extends out of the mixing drum 2. The lifting mechanism 4 lifts the raw materials in the feed bin 3 into the inner drum 6. The stirring shaft drives the stirring rod 5 to rotate, thereby stirring the raw materials evenly. The spiral blades 402 continuously lift the raw materials into the inner drum 6. The raw materials gradually accumulate and rise, and are automatically discharged from the discharge notch 601 into the discharge pipe 7. They are then discharged downwards along the discharge pipe 7 to the outside for further melting processing. The discharge notch 601 can be set relatively deep, so that the mixed raw materials automatically slide down from the discharge notch 601 into the discharge pipe 7, preventing the raw materials from falling from the top of the inner drum 6.

[0019] The inner cylinder 6 is equipped with spiral blades 402 connected to a rotating shaft 401 for lifting the raw materials in the inner cylinder 6. By rotating the spiral blades 402 in the inner cylinder 6 under the drive of the rotating shaft 401, the raw materials in the inner cylinder 6 are gradually lifted upwards, avoiding the difficulty of lifting heavier raw materials in the inner cylinder 6 by the spiral blades 402 in the feed cylinder 201 alone.

[0020] The support frame 1 is also equipped with a motor 8 that is connected to the lower end of the rotating shaft 401 via a worm gear transmission. The motor 8 drives the rotating shaft 401 to rotate, which in turn drives the spiral blades 402 and the stirring rod 5 to rotate, thereby lifting the raw materials and mixing them evenly.

[0021] The feeding hopper 3 has a triangular structure, with an inclined bottom surface that facilitates the automatic sliding of raw materials. The lowest point of the inclined surface is the mounting point of the lower end of the rotating shaft 401. When various raw materials are poured into the feeding hopper 3, they will automatically slide down the inclined surface into the feeding cylinder 201 and be lifted into the mixing cylinder 2. The triangular structure allows the raw materials to automatically converge at the lower end of the feeding cylinder 201.

[0022] Work process:

[0023] In use, the device simply requires adding various plastic raw material granules that need to be mixed into the feed hopper 3. The motor 8 drives the rotating shaft 401 to rotate, which in turn drives the spiral blades 402 and the stirring rod 5 to rotate. The spiral blades 402 lift the raw materials in the feed hopper 3 upwards and through the feed cylinder 201 to the stirring cylinder 2. The stirring rod 5 rotates to stir the raw materials. The spiral blades 402 continuously lift the raw materials into the inner cylinder 6. The spiral blades 402 in the inner cylinder 6 rotate under the drive of the rotating shaft 401, gradually lifting the raw materials in the inner cylinder 6 upwards. The raw materials gradually accumulate and rise, and are automatically discharged from the discharge outlet 601 into the discharge pipe 7. They are then discharged downwards along the discharge pipe 7 to the outside for further melting and processing.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
