The auxiliary device 6 is provided on the surface of the feed inlet 2.

[0022] Specifically, the auxiliary device 6 includes a guide pipe 61. The guide pipe 61 is fixedly connected with one side surface of the feed inlet 2, and the guide pipe 61 is communicated with the feed inlet 2. A filter member 62 is fixedly connected to the inner wall of the feed inlet 2. Two pressing rollers 68 are rotatably connected to the inner wall of the guide pipe 61.

A cleaning assembly 65 is provided on the surface of the feed inlet 2.

[0023] In this implementation scheme: when discharging materials, the filter member 62 can intercept large pieces of materials in the powder. After interception, since the filter member 62 is inclined at a certain angle, the materials will be introduced into the guide pipe 61. Subsequently, the two second motors 69 drive the two pressing rollers 68 to rotate counterclockwise and clockwise respectively, so that the two pressing rollers 68 crush the large pieces of materials, and after crushing, they directly enter the feed inlet 2 to continue discharging materials.

[0024] Specifically, a first guide block 63 and a second guide block 64 are fixedly connected to the inner wall of the guide pipe 61. The guide surfaces of the first guide block 63 and the second guide block 64 are inclined surfaces, and the first guide block 63 and the second guide block 64 can introduce large pieces of materials into the two pressing rollers 68 for direct crushing treatment.

[0025] Specifically, a first scraping member 66 and a second scraping member 67 are fixedly connected to the inner wall of the guide pipe 61 below the pressing roller 68. Both the first scraping member 66 and the second scraping member 67 are made of rubber material.

[0026] In this implementation scheme: the first scraping member 66 and the second scraping member 67 can clean the powder contaminated on the pressing roller 68 and scrape away the powder for discharging materials.

[0027] Specifically, the scraping ends of the first scraping member 66 and the second scraping member 67 are provided with tips.

[0028] Specifically, the cleaning assembly 65 includes a transmission rod 651. The transmission rod 651 is fixedly connected to one end of the pressure roller 68. A driven rod 652 is rotatably connected to one side surface of the feed inlet 2. A belt 654 is arranged on the surfaces of the transmission rod 651 and the driven rod 652. A first gear 653 is fixedly connected to the surface of the driven rod 652. The first gear 653 is a non-full-tooth structure. A flapping member 655 is arranged on the inner wall of the feed inlet 2. When the pressure roller 68 rotates, it can drive the transmission rod 651 to rotate. The transmission rod 651 drives the driven rod 652 and the first gear 653 to rotate through the belt 654. The first gear 653 can drive the flapping member 655 to move, so as to realize the flapping of the flapping member 655 on the filter element 62.

[0029] Specifically, the flapping member 655 includes a rotating shaft 6552. The rotating shaft 6552 is rotatably connected to the inner wall of the feed inlet 2. A flapping rod 6553 is fixedly connected to one end of the rotating shaft 6552. A second gear 6551 is fixedly connected to the other end of the rotating shaft 6552. The first gear 653 is meshed with the second gear 6551. A spring 6554 is sleeved on the surface of the rotating shaft 6552. The two ends of the spring 6554 are respectively fixedly connected to the second gear 6551 and the surface of the feed inlet 2.

[0030] In this embodiment: When the flapping member 655 moves, the non-full-tooth first gear 653 drives the second gear 6551, the rotating shaft 6552 and the flapping rod 6553 to rotate. When the first gear 653 loses contact with the second gear 6551, the spring 6554 drives the rotating shaft 6552 and the flapping rod 6553 to reset. The flapping rod 6553 flaps on the filter element 62, and can shake off the dust on the filter element 62.

[0031] Working principle: When the device is feeding, first pour the powder into the feeding port 2. After the powder enters the feeding port 2, it will pass through the filter element 62. The filter element 62 can intercept large pieces of materials in the powder. Due to the certain inclination of the filter element 62, the intercepted materials are guided into the guide pipe 61 by the filter element 62. Subsequently, the first guide block 63 and the second guide block 64 cooperate to guide the large pieces of materials to the two pressure rollers 68. The two second motors 69 drive the pressure rollers 68 to rotate counterclockwise and clockwise respectively, so as to crush the large pieces of materials. The crushed materials are guided into the feeding port 2 through the guide pipe 61 for feeding. At the same time, the first scraping member 66 and the second scraping member 67 can scrape off the powder contaminated on the pressure rollers 68. When the pressure rollers 68 rotate, they can drive the transmission rod 651 to rotate. The transmission rod 651 drives the driven rod 652 and the first gear 653 to rotate through the belt 654. The first gear 653 with non-full teeth drives the second gear 6551, the rotating shaft 6552 and the beating rod 6553 to rotate. When the first gear 653 loses contact with the second gear 6551, the spring 6554 drives the rotating shaft 6552 and the beating rod 6553 to reset. The beating rod 6553 beats on the filter element 62, and can shake off the dust on the filter element 62. Subsequently, the first motor 5 can cooperate with the spiral member 4 to drive the powder to move and feed through the discharge port 3.
