[0055] Among them, a crushing mechanism and an anti-blocking mechanism are arranged in the noise reduction box 1;

[0056] The crushing mechanism includes two positioning shafts 6, two crushing rollers 7, two gears 8, a motor 9 and a feed pipe 5;

[0057] The anti-blocking mechanism includes a first mounting plate 10 , a second mounting plate 11 , a fixed shaft 12 , a stirring rod 13 , a clockwork spring 14 and a fixed block 15 .

[0058] Furthermore, the feed pipe 5 is fixedly connected to the lower surface of the feed hopper 4, and the feed pipe 5 is communicated with the inside of the feed hopper 4;

[0059] Wherein, the feed pipe 5 penetrates downwardly out of the lower surface of the noise reduction box 1;

[0060] Among them, two positioning shafts 6 are rotatably connected between the front and rear inner walls of the feed pipe 5;

[0061] The front ends of the two positioning shafts 6 rotate and penetrate the front side surface of the feed pipe 5 .

[0062] Furthermore, the motor 9 is fixedly connected to the front inner wall of the noise reduction box 1;

[0063] The rotating output shaft of the motor 9 is fixedly connected to the front end of the right positioning shaft 6;

[0064] The two crushing rollers 7 are fixedly sleeved on the outer surfaces of the two positioning shafts 6 , and the crushing rollers 7 are located in the feeding pipe 5 , and the two crushing rollers 7 are adapted to each other.

[0065] Furthermore, the rear ends of the two positioning shafts 6 rotate to penetrate the rear side surface of the feed pipe 5;

[0066] Among them, two gears 8 are fixedly connected to the rear ends of the two positioning shafts 6;

[0067] Among them, two gears 8 are meshed and connected;

[0068] The fixed shaft 12 is rotatably connected between the front and rear inner walls of the feed pipe 5 .

[0069] Furthermore, the front end of the fixed shaft 12 rotates and penetrates the front side surface of the feed pipe 5;

[0070] Wherein, the first mounting plate 10 is fixedly connected to the outer surface of the right positioning shaft 6 outside the feed pipe 5;

[0071] Wherein, the fixing block 15 is fixedly connected to the front surface of the feed pipe 5;

[0072] The spring 14 is sleeved outside the fixed shaft 12, and the inner end of the spring 14 is fixedly connected to the fixed shaft 12;

[0073] The outer end of the mainspring 14 is fixedly connected to the fixing block 15 .

[0074] Furthermore, the second mounting plate 11 is fixedly connected to the outer surface of the fixed shaft 12 outside the feed pipe 5;

[0075] The second mounting plate 11 is arranged in an inclined manner, and the second mounting plate 11 is slidably connected to the first mounting plate 10;

[0076] Wherein, a plurality of stirring rods 13 are fixedly connected to the outer surface of the fixed shaft 12;

[0077] The stirring rod 13 is located in the feeding pipe 5 .

[0078] Furthermore, in the initial state, the second mounting plate 11 is in an inclined state. When in use, the motor 9 needs to be started. When the motor 9 is started, the two positioning shafts 6 are driven by the gear 8 to rotate, and then the two crushing rollers 7 are synchronously driven to crush the material with larger particles, so that the material particles are more uniform, and the molding quality of the material is guaranteed;

[0079] As mentioned above, when the motor 9 is started, the first mounting plate 10 is also driven to rotate synchronously. During the rotation of the first mounting plate 10, it contacts the second mounting plate 11 and pushes the second mounting plate 11 to rotate around the fixed shaft 12. In this process, the fixed shaft 12 is synchronously driven to rotate, and the fixed shaft 12 drives the stirring rod 13 to stir the feed pipe 5. The rotation process of the fixed shaft 12 causes the spring 14 to tighten and deform. When the first mounting plate 10 rotates to no longer contact the second mounting plate 11, under the action of the released elastic force of the spring 14, the fixed shaft 12, the second mounting plate 11 and the stirring rod 13 are driven to return to their initial state, and then the motor 9 drives the stirring rod 13 to rotate back and forth in a fan shape around the fixed shaft 12 as the center for each rotation of the motor 9. The rotation of the stirring rod 13 can avoid blockage in the feed pipe 5, thereby ensuring the stability of the feeding device and the efficiency of the ball press production, thereby increasing the practicality of the feeding device.

[0080] Furthermore, in this solution, the elastic force of the mainspring 14 is large enough so that the stirring rod 13 and the fixed shaft 12 can have enough force to reset;

[0081] Furthermore, in the present solution, the noise reduction materials in the noise reduction box 1 can be: sound insulation board, sound insulation felt, sound absorbing cotton and polyester fiber sound absorbing board, etc. The above materials can have a good sound insulation effect and attenuate the sound waves, thereby reducing the noise of the feeding device during crushing, thereby reducing the noise pollution of the feeding device and increasing the practicality of the device.

[0082] Furthermore, the protection plate 3 can prevent the material from splashing out of the fixing frame 2 to a certain extent, which can avoid material waste on the one hand and ensure the safety of the staff on the other hand, thereby increasing the practicality and safety of the feeding device.

[0083] Working principle: When the device is used, in the initial state, the second mounting plate 11 is in an inclined state. When in use, the motor 9 needs to be started. The motor 9 starts and drives the two positioning shafts 6 to rotate under the drive of the gear 8, and then synchronously drives the two crushing rollers 7 to crush the materials with larger particles, so that the material particles are more uniform, ensuring the molding quality of the material;

[0084] As mentioned above, when the motor 9 is started, the first mounting plate 10 is also driven to rotate synchronously. During the rotation of the first mounting plate 10, it contacts the second mounting plate 11 and pushes the second mounting plate 11 to rotate around the fixed shaft 12. In this process, the fixed shaft 12 is synchronously driven to rotate, and the fixed shaft 12 drives the stirring rod 13 to stir the feed pipe 5. The rotation process of the fixed shaft 12 causes the spring 14 to tighten and deform. When the first mounting plate 10 rotates to no longer contact the second mounting plate 11, under the action of the released elastic force of the spring 14, the fixed shaft 12, the second mounting plate 11 and the stirring rod 13 are driven to return to their initial state, and then the motor 9 drives the stirring rod 13 to rotate back and forth in a fan shape around the fixed shaft 12 as the center for each rotation of the motor 9. The rotation of the stirring rod 13 can avoid blockage in the feed pipe 5, thereby ensuring the stability of the feeding device and the efficiency of the ball press production, thereby increasing the practicality of the feeding device.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
