[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: a feeding structure for producing polyimide film raw materials, including a feeding plate 1, a discharge hopper 2 connected to the top of the feeding plate 1, a second storage tank 3 rotatably connected to the top of the discharge hopper 2, a first storage tank 4 rotatably connected to the top of the second storage tank 3, a stirring assembly 5 rotatably connected to the middle position inside both the first storage tank 4 and the second storage tank 3, and a discharge port 6 opened on the inner bottom wall of both the first storage tank 4 and the second storage tank 3, and a guide block 7 is also provided on the inner bottom wall of the first storage tank 4 and the second storage tank 3, with the discharge port 6 and the guide block 7 distributed at intervals. The stirring assembly 5 includes a stirring cylinder and multiple stirring plates, which are arranged in a ring array on the outer circumference of the stirring cylinder. A third motor 13 is provided on the outer wall of both the first storage tank 4 and the second storage tank 3, and the output shaft of the third motor 13 is connected to the stirring assembly 5.

[0024] In the above technical solution, the third motor 13 drives the stirring component 5 to rotate, and the rotation of the stirring component 5 drives the raw materials in the storage tank to move, thereby stirring and mixing the raw materials in the storage tank, saving time.

[0025] The top of the first storage box 4 is open, and the top of the second storage box 3 is provided with a through hole that communicates with the discharge port 6 at the bottom of the first storage box 4.

[0026] In the initial state, the discharge port 6 at the bottom of the first storage box 4 does not coincide with the through hole at the top of the second storage box 3. Only when the first storage box 4 is rotated until the discharge port 6 coincides with the through hole at the top of the second storage box 3 can the raw materials inside the first storage box 4 be introduced into the second storage box 3 for a second stirring and mixing.

[0027] like Figure 3As shown, the discharge port 6 has a fan-shaped structure, the bottom cross-section of the guide block 7 has a fan-shaped structure, and the top of the guide block 7 is provided with an inclined surface. The guide block 7 guides all the raw materials to the discharge port 6, which is conducive to the smooth discharge of the raw materials.

[0028] The top of the discharge hopper 2 is provided with a through hole that communicates with the discharge port 6 at the bottom of the second storage box 3, and the bottom of the discharge hopper 2 is open.

[0029] In the initial state, the discharge port 6 at the bottom of the second storage box 3 does not coincide with the through hole at the top of the discharge hopper 2. Only when the second storage box 3 rotates until the discharge port 6 coincides with the through hole at the top of the discharge hopper 2 can the raw material inside the second storage box 3 be guided into the discharge hopper 2, thereby realizing the entry of the raw material into the feed plate 1.

[0030] like Figures 1-2 As shown, the lower outer walls of the first storage bin 4 and the second storage bin 3 are both provided with arc-shaped racks 8, and the two ends of the arc-shaped racks 8 are provided with limiting blocks to prevent the gears from disengaging from the arc-shaped racks 8; the upper outer wall of the second storage bin 3 is provided with a first motor 9, and the output shaft of the first motor 9 is connected to a first gear 10; the upper outer wall of the discharge hopper 2 is provided with a second motor 11, and the output shaft of the second motor 11 is connected to a second gear 12; the first gear 10 and the second gear 12 are respectively meshed with the arc-shaped racks 8 on the first storage bin 4 and the second storage bin 3.

[0031] The first motor 9 drives the first gear 10 to rotate, thereby driving the first storage box 4 to rotate to open its discharge port 6 for material discharge; the second motor 11 drives the second gear 12 to rotate, thereby driving the second storage box 3 to rotate to open its discharge port 6 for material discharge.

[0032] By restricting the arc-shaped rack 8, both the first storage box 4 and the second storage box 3 can only rotate 90 degrees. At this time, the discharge port 6 is in a fully open state.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
