[0019] like Figure 1-2 As shown, Figure 1 This is a side sectional view of a medicinal material grinding and filtering system proposed by the present invention. Figure 2 This is a front cross-sectional view of a medicinal material grinding and filtering system proposed by the present invention.

[0020] Reference Figure 1-2 The present invention provides a medicinal material grinding and filtering system, characterized in that it comprises: a base 1, a shell 2, a screen 3, a rotating body component, a first roller pressing component, a scraper 4, a second roller pressing component, a control component, and a proximity sensor component;

[0021] The shell 2, the swivel assembly, the first roller assembly, and the second roller assembly are all fixedly mounted on the base 1, and the shell 2 has a cylindrical and horizontally arranged first chamber, a feed port and a discharge port are provided on the shell 2, the discharge port is located at the bottom of the shell 2, and the screen 3 is adapted to be arranged at the discharge port;

[0022] The swivel 5 of the swivel assembly has a cylindrical and horizontally arranged second chamber, the first chamber is coaxially arranged with the second chamber, filtering holes are evenly arranged on the swivel 5, one end of the radially arranged scraper 4 is fixed on the swivel 5, and the other end is against the inner wall of the first chamber, and a notch is opened on the swivel 5, and one end surface of the notch is coplanar with the working surface 41 of the scraper 4; the swivel 5 rotates at a uniform speed at a first angular velocity, and in the rotation direction of the swivel 5, the notch is located in front of the scraper 4;

[0023] Driven by the power source of the first rolling assembly, the first pressing roller 6 of the first rolling assembly arranged in the second chamber moves axially in contact with the inner wall of the second chamber;

[0024] The proximity sensor assembly is fixedly mounted on the swivel 5 to detect whether the second pressure roller 7 of the second pressure roller assembly is close to the scraper 4; the control assembly is used to control the second pressure roller assembly to drive the second pressure roller 7 to avoid the scraper 4 and move in close contact with the inner wall of the first chamber.

[0025] During the specific working process of the medicinal material grinding and filtering system of this embodiment, medicinal materials are fed from the feed port, and the medicinal materials slide to the bottom of the first chamber by their own weight. During the rotation of the swivel 5, the scraper 4 lifts the medicinal materials between the swivel 5 and the shell 2. When the gap moves to the upper part, the medicinal materials slide into the second chamber by their own weight along the working surface 41 of the scraper 4. The first pressing roller 6 swings back and forth in the second chamber, crushing the medicinal materials to a suitable particle size and leaking them to the bottom of the first chamber of the shell 2 through the filter hole. Small particles of medicinal materials will be filtered through the screen 3, and the medicinal materials that cannot be filtered will be crushed by the second pressing roller 7. The medicinal materials crushed into small particles will be directly filtered through the screen 3. The medicinal materials that cannot be filtered will be brought into the second chamber again by the scraper 4 and crushed again by the first pressing roller 6, and this cycle will repeat.

[0026] When the proximity sensor component does not detect that the second pressing roller 7 is close to the scraper 4, the control component controls the second pressing roller 7 to reciprocate in the screen area to repeatedly crush and move the medicinal materials in the first chamber.

[0027] When the proximity sensing component detects that the second pressure roller 7 approaches the scraper 4 , the control component controls the second pressure roller 7 to move away from the scraper 4 to prevent the second pressure roller 7 from touching the scraper 4 and thus affecting the operation of the scraper 4 .

[0028] In this embodiment, the proposed medicinal material grinding and filtering system feeds the medicinal materials from the feed port, and part of the medicinal materials slide down into the first chamber due to their own weight, so as to prevent all the medicinal materials from entering the second chamber and causing excessive accumulation of medicinal materials, which affects the operation of the first pressing roller 6; and through the movement of the second pressing roller 7, the medicinal materials accumulated in large quantities at the bottom of the first chamber are stirred and lifted, so as to prevent excessive accumulation of medicinal materials at the bottom of the first chamber and cause blockage of the screen 3; and the second pressing roller 7 can further crush the medicinal materials during the movement on the screen 3, and can also prompt the medicinal materials to move back and forth on the screen 3, so as to promote further filtration of the medicinal materials; at the same time, continuous feeding of medicinal materials can be realized, and the device has a simple process, high efficiency, and can be fully automated.

[0029] In a specific embodiment, when the proximity sensing component detects that the second roller 7 of the second roller pressing component approaches from the front of the working surface 41 of the scraper 4, the control component controls the second roller pressing component to accelerate the second roller 7 to move at a second angular velocity, and the second angular velocity is greater than or equal to the first angular velocity;

[0030] When the proximity sensing component detects that the second pressing roller 7 approaches from behind the working surface 41 of the scraper 4, the control component controls the second roller pressing component to decelerate the second pressing roller 7 to move at a third angular velocity, which is less than or equal to the first angular velocity.

[0031] When the proximity sensing component does not detect the approach of the second pressing roller 7, the control component controls the second pressing roller 7 to reciprocate in the screen area.

[0032] During the operation of the scraper 4 and the second pressing roller 7, when the proximity sensing component detects that the second pressing roller 7 approaches from the front of the working surface 41 of the scraper 4, the control component controls the second pressing roller component to accelerate the second pressing roller 7 to the second angular velocity; at this time, the second pressing roller 7 stirs and lifts the medicinal materials in the first chamber to prevent the accumulation of medicinal materials at the bottom of the first chamber, which causes the screen 3 to be blocked, and at the same time, the medicinal materials that are excessively accumulated at the bottom of the first chamber are brought up, which is conducive to the normal operation of the scraper 4; the second angular velocity is greater than the first angular velocity, which can prevent the second pressing roller 7 from colliding with the scraper 4; when the proximity sensing component detects that the second pressing roller 7 approaches from the rear of the working surface 41 of the scraper 4, the control component controls the second roller pressing component to decelerate the second pressing roller 7 to the third angular velocity; so that the second pressing roller 7 maintains a certain safety distance from the scraper 4 to prevent the second pressing roller 7 from colliding with the scraper 4; when the proximity sensing component does not detect that the second pressing roller 7 approaches, the control component controls the second pressing roller 7 to reciprocate in the screen area to repeatedly crush and move the medicinal materials in the first chamber.

[0033] Furthermore, the base 1 is provided with a storage cavity and the storage cavity is located directly below the discharge port. The arrangement of the storage cavity facilitates direct storage or packaging of medicinal materials.

[0034] Furthermore, the working surface of the first pressing roller 6 has uniformly arranged first protrusions, which have a further crushing effect on the medicinal materials, thereby improving the grinding efficiency of the first pressing roller 6 on the medicinal materials.

[0035] Furthermore, the aperture of the filter hole is larger than that of the screen 3 , and part of the medicinal materials in the second chamber falls into the first chamber, thereby preventing excessive accumulation of medicinal materials in the second chamber, which would affect the operation of the pressing roller 6 .

[0036] Furthermore, the working surface of the second pressing roller 7 has uniformly arranged second protrusions, which have a further crushing effect on the medicinal materials, thereby improving the grinding efficiency of the second pressing roller 7 on the medicinal materials.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
