[0002] In the filter paper production process, it is often necessary to pulverize the raw materials used to produce the filter paper. Existing filter paper raw material pulverizing devices have a relatively simple structure, resulting in poor pulverization effects and a tendency for the raw materials to be incompletely pulverized. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a raw material crushing device for filter paper production. This device solves the problems of existing filter paper raw material crushing devices having relatively simple structures, poor crushing effects, and a tendency for incomplete crushing of raw materials.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 2 As shown,

[0019] A raw material crushing device for filter paper production, characterized in that it includes a frame 2, a crushing box 3 slidably connected to the upper end of the frame 2, a feed hopper 4 connected to the upper end of the crushing box 3, a discharge port 5 opened at the lower end of the crushing box 3, a first push rod motor 6 fixedly connected to the upper end of the frame 2 to drive the crushing box 3 to move, two first rotating rods 7 rotatably connected to the upper end of the crushing box 3, a plurality of first crushing blades 8 fixedly connected to the first rotating rods 7, a first drive motor 9 for driving the first rotating rods 7 to rotate on the crushing box 3, a row of filter cylinders 10 placed on the frame 2 below the crushing box 3, a collection box 11 fixedly connected to the frame 2 below the filter cylinders 10, and a discharge pipe 12 provided at the lower end of the collection box 11.

[0020] In this embodiment, the filter paper raw material to be pulverized is added into the pulverizing chamber 3 from the feed hopper 4. The first drive motor 9 drives the first rotating rod 7 and the first pulverizing blade 8 to rotate, contacting and pulverizing the added filter paper raw material. The pulverized filter paper raw material falls into the filter cylinder 10 below from the discharge port 5. The properly pulverized filter paper raw material passes through the filter cylinder 10 and falls into the collection box 11 below. The improperly pulverized filter paper raw material is left in the filter cylinder 10. After a period of use, a certain amount of improperly pulverized filter paper raw material accumulates in one of the filter cylinders 10. At this time, the first push rod motor 6... The crushing chamber 3 is moved so that the discharge port 5 is aligned with another filter cylinder 10. At this time, the worker can pour the filter paper raw material in the already full filter cylinder 10 back into the feed hopper 4 to continue crushing until it is crushed to the required level. Then it passes through the filter cylinder 10 and falls into the collection box 11. The qualified filter paper raw material is finally discharged from the discharge pipe 12. The filter cylinder 10 intercepts the uncrushed filter paper raw material and sends it back to the crushing chamber to avoid the problem of uncrushed filter paper raw material. Multiple filter cylinders 10 are used alternately, so the crushing work is not affected when unqualified filter paper raw material is poured out.

[0021] In this embodiment, two extrusion rollers 13 are symmetrically rotatably connected inside the feed hopper 4, and a second drive motor 14 is provided on the feed hopper 4 to drive the extrusion rollers 13 to rotate. By extruding the filter paper raw material through the extrusion rollers 13, the crushing efficiency and effect of the filter paper raw material are improved.

[0022] In this embodiment, the two first rotating rods 7 are symmetrically distributed about the vertical center line of the feed hopper 4, and the first crushing blades 8 on the two first rotating rods 7 are staggered. The staggered distribution of the first crushing blades 8 improves the crushing effect of the filter paper raw material.

[0023] In this embodiment, a second rotating rod 15 is rotatably connected inside the pulverizing chamber 3. A second pulverizing blade 16 is mounted on the second rotating rod 15. A third drive motor 17 is mounted on the pulverizing chamber 3 to drive the second rotating rod 15 to rotate. The second pulverizing blade 16 is located below the first pulverizing blade 8. By driving the second rotating rod 15 and the second pulverizing blade 16 to rotate via the third drive motor 17, the filter paper raw material is pulverized a second time, improving the pulverization effect.

[0024] In this embodiment, a second push rod motor 18 is fixedly connected to the frame 2, and a limiting frame 19 is fixedly connected to the push rod of the second push rod motor 18. The filter cylinder 10 is located inside the limiting frame 19. The second push rod motor 18 drives the limiting frame 19 to move back and forth, causing the filter cylinder 10 inside the limiting frame 19 to shake, thus accelerating the falling of the filter paper raw material.

[0025] In this embodiment, the top of the feed hopper 4 is funnel-shaped.
