Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and particularly to an efficient crushing device for pharmaceutical manufacturing. Background Art

[0002] Pharmaceutical crushing is to break the lumpy pharmaceutical raw materials into powder form to facilitate dissolving them in water to react with other raw materials or mixing them with other powders. Therefore, pharmaceutical crushing is a basic step in pharmaceutical processing. In the pharmaceutical crushing process, two relatively rotating roller mills are often used to squeeze and crush the pharmaceuticals between them. Since the shape of the roller mills is circular, when the opening angle between the two roller mills is too large, when the raw materials fall onto the two roller mills, it is difficult for the roller mills to carry the raw materials between the two roller mills for crushing treatment, and the crushing effect is poor.

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0027] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0029] As Figures 2 to 3 shown, the high-efficiency crushing device for drug manufacturing of the present invention includes a support cylinder 1, a grinding plate 2, and two pressing plates located on the front and rear sides of the grinding plate 2. The grinding plate 2 is rotatably installed on the support cylinder 1, and both pressing plates are fixed on the support cylinder 1;

[0030] The pressing plate is composed of a grinding plate 3 and an inclined plate 4. The grinding plate 3 is parallel to the grinding plate 2. The inclined plate 4 is inclinedly installed on the top of the grinding plate 3, and the projection of the grinding plate 3 on the vertical plane and the projection of the inclined plate 4 on the vertical plane form a complete circle. The inclined plate 4 forms an angle with the grinding plate 2. A partition plate 5 is vertically arranged on the inclined plate 4. The partition plate 5 is in sliding contact with the end face of the grinding plate 2. The grinding plate 2 on one side of the partition plate 5 rotates downward, and the included angle space formed by the inclined plate 4 and the grinding plate 2 on this side is used for feeding. The grinding plate 2 on the other side of the partition plate 5 rotates upward.

[0031] Specifically, the support cylinder 1 is used to support the grinding plate 2 and the pressing plate. The included angle between the inclined plate 4 on the pressing plate and the grinding plate 2 is small, and its opening size can be determined according to the actual situation. The raw material can be placed between the grinding plate 2 and the inclined plate 4 on one side of the partition plate 5. The inclined plate 4 guides the raw material. The rotating grinding plate 2 can carry the raw material into the space between the grinding plate 2 and the grinding plate 3. During the process that the raw material moves downward on the inclined plate 4 and enters the grinding plate 2 and the grinding plate 3, the raw material is broken. Since the included angle between the inclined plate 4 and the grinding plate 2 is small, it is more convenient to perform extrusion and crushing treatment on the raw material, avoiding the situation that the raw material cannot enter the space between the grinding plate 2 and the grinding plate 3 due to the too large opening angle between the inclined plate 4 and the grinding plate 2. Thus, the device can crush the raw material more smoothly and improve the functionality of the device.

[0032] By setting the partition plate 5, it is convenient to partition the area between the inclined plate 4 and the grinding disk 2, avoiding the raw materials from moving to the upward rotating side of the grinding disk 2. The raw materials that have undergone crushing treatment can be discharged at the bottom of the grinding disk 2 and the grinding plate 3. Since the grinding disk 2 and the grinding plate 3 are used in combination to crush the raw materials, the area between the grinding disk 2 and the grinding plate 3 is relatively large, thus effectively prolonging the raw material crushing process, facilitating the long-term extrusion and crushing of the raw materials, improving the crushing effect. And because the grinding disk 2 rotates, the movement trajectory of the points on the end face of the grinding disk 2 is arc-shaped. In this way, the trajectory of the frictional force of the end face of the grinding disk 2 on the raw materials is arc-shaped, which is convenient for generating forces on the raw materials in different directions, facilitating the crushing treatment of the raw materials, and avoiding the rolling of the raw materials when a single-direction frictional force is generated on the raw materials. Therefore, strip-shaped raw materials can be crushed. By using the method of combining two pressing plates with the grinding disk 2, the raw materials can be crushed on both the front and rear sides of the grinding disk 2, thereby improving the raw material processing efficiency.

[0033] By adopting the method of combining the grinding disk 2 and the inclined plate 4, it is convenient to make the opening angle between the grinding disk 2 and the inclined plate 4 smaller. In this way, the rotating grinding disk 2 can smoothly carry the raw materials to the area between the grinding disk 2 and the grinding plate 3 for crushing treatment, avoiding the situation where the raw materials cannot smoothly enter the area between the grinding disk 2 and the grinding plate 3 when the opening angle is too large, effectively improving the equipment's ability to crush the raw materials and enhancing the equipment's functionality. At the same time, since the end face of the grinding disk 2 and the grinding plate 3 are used in combination to crush the raw materials, the raw material crushing process can be greatly prolonged, facilitating the full crushing of the raw materials and improving the crushing effect.

[0034] Preferably, as Figure 1 shown, it further includes an outer box body 6. The support cylinder 1, the grinding disk 2 and the pressing plate are all located inside the outer box body 6. The support cylinder 1 is fixed inside the outer box body 6. A three-way pipe 7 is connected and provided at the top of the outer box body 6, and a discharge pipeline 8 is connected and provided at the bottom of the outer box body 6.

[0035] Specifically, the outer box body 6 can support the support cylinder 1, the grinding disk 2 and the pressing plate, and it can enable the raw materials to be crushed in a closed space, avoiding the random scattering of the raw materials. The raw materials can be discharged into the feeding areas on both the front and rear sides of the grinding disk 2 through the three-way pipe 7, and the raw materials that have undergone crushing treatment can be discharged through the discharge pipeline 8;

[0036] The outer walls of the grinding disk 2, the grinding plate 3 and the inclined plate 4 are all in contact with the inner wall of the outer box body 6, and the grinding disk 2 rotates inside the outer box body 6.

[0037] Preferably, as Figures 1 to 2As shown, the connecting line between the grinding plate 3 and the inclined plate 4 is inclined in the vertical plane. The area where the connecting line on one side of the partition plate 5 inclines upward is set as the feeding area, while the area where the connecting line on the other side of the partition plate 5 inclines downward is set as the cleaning area. A scraping plate 10 is inclinedly arranged in the cleaning area. The scraping plate 10 is fixed on the inclined plate 4, and an inclined pipe 9 is inclinedly communicated with the outer wall of the outer box body 6.

[0038] Specifically, raw materials can be introduced into the feeding area. Since the connecting line in this area inclines upward and is combined with the partition plate 5, the shape of this area is in the shape of a hopper, which is convenient for gathering the raw materials. The scraping plate 10 in the cleaning area can scrape and clean the raw material debris adhered to the end face of the rotating grinding disc 2. Since the connecting line in this area inclines downward, the scraped debris can move obliquely towards the inclined pipe 9 and be discharged into the external collecting device through the inclined pipe 9.

[0039] Preferably, as Figures 4 to 6 shown, tooth grooves 11 are formed on the circumferential inner wall of the grinding disc 2, a notch is formed on the inner wall of the support cylinder 1, and a first motor 12 is fixed on the inner wall of the support cylinder 1. A gear 13 is provided at the output end of the first motor 12. The gear 13 passes through the notch and meshes with the tooth grooves 11.

[0040] Specifically, the first motor 12 can drive the grinding disc 2 to rotate through the gear 13 and the tooth grooves 11, thereby providing power for the grinding disc 2. At the same time, this structural method can conveniently hide the tooth grooves 11, the first motor 12 and the gear 13, so as to avoid damage caused by powder.

[0041] Preferably, as Figure 2 shown, first connecting plates 15 are arranged on the outer side walls of the grinding plate 3 and the inclined plate 4. A slider 14 is connected to the first connecting plate 15. The slider 14 is slidably installed on the support cylinder 1, and the slider 14 slides along the axial direction of the support cylinder 1;

[0042] A power mechanism is arranged in the support cylinder 1. The power mechanism is used to adjust the distance between the two pressing plates and the grinding disc 2.

[0043] Specifically, the power mechanism can drive the slider 14 to slide on the support cylinder 1, thereby adjusting the distance between the pressing plate and the grinding disc 2, which is convenient for crushing raw materials with different crushing requirements.

[0044] Preferably, as Figures 6 to 7 shown, the power mechanism includes a core column 16 located in the middle of the support cylinder 1. The core column 16 is coaxial with the support cylinder 1. Threaded rods 17 are arranged at the front and rear ends of the core column 16. The thread directions of the two threaded rods 17 are opposite. A thread sleeve 18 is arranged on each threaded rod 17. The thread sleeve 18 is threadedly connected with the threaded rod 17. Two second connecting plates 19 are arranged on the thread sleeve 18. The second connecting plates 19 are fixedly connected with the slider 14;

[0045] A second motor 20 is fixed on the inner wall of the support cylinder 1. A tooth column 21 is provided at the output end of the second motor 20. A sliding sleeve 28 is arranged on the outer wall of the core column 16. Teeth are arranged on the outer wall of the sliding sleeve 28. The tooth column 21 meshes with the teeth on the sliding sleeve 28.

[0046] Specifically, the second motor 20 can drive the core column 16 to rotate through the tooth column 21 and the sliding sleeve 28. The core column 16 can drive two threaded rods 17 thereon to rotate, so as to push the threaded sleeve 18 to move along the axis direction of the support cylinder 1 through the threaded rods 17. Since the thread directions of the two threaded rods 17 are opposite, the moving directions of the two threaded sleeves 18 are opposite. The threaded sleeve 18 drives the slider 14 to move through the second connecting plate 19, so as to provide power for the pressing plate, and the two pressing plates move synchronously and in opposite directions.

[0047] Preferably, as Figure 6 shown, a third connecting plate 22 is arranged at the end of the threaded rod 17 on one side of the core column 16, and the threaded rod 17 is rotatably installed on the third connecting plate 22. The third connecting plate 22 is fixed on the support cylinder 1. A rhombic jack is opened at the end of the threaded rod 17 on the other side of the core column 16. A prism 23 is slidably inserted in the rhombic jack. The end of the prism 23 extends beyond the threaded rod 17. A sliding plate 24 is fixed on the prism 23. The sliding plate 24 is slidably installed on the inner wall of the support cylinder 1, and the sliding direction of the sliding plate 24 is along the axis direction of the support cylinder 1. The sliding plate 24 is connected with the support cylinder 1 through a leaf spring 25.

[0048] Specifically, the leaf spring 25 provides an elastic thrust to the sliding plate 24 and the prism 23, so that the prism 23 is stuck in the rhombic jack. With the shape limitation of the prism 23 and the rhombic jack, the two threaded rods 17 and a core column 16 are locked in position, which is convenient for locking the position of the pressing plate. When the position of the pressing plate needs to be adjusted, push the prism 23 to pull out of the rhombic jack, and at this time the sliding plate 24 slides on the support cylinder 1.

[0049] Preferably, as Figure 6 shown, a plurality of spiral grooves 26 are opened on the circumferential outer wall of the core column 16. A plurality of sliding edges are arranged on the circumferential inner wall of the sliding sleeve 28. The sliding edges are slidably installed in the spiral grooves 26, so that the sliding sleeve 28 is slidably installed on the core column 16. An annular sliding groove is opened on the circumferential outer wall of the sliding sleeve 28. A fourth connecting plate 27 is slidably arranged on the sliding groove. The end of the fourth connecting plate 27 is fixedly connected with the sliding plate 24.

[0050] Specifically, when it is necessary to adjust the position of the pressing plate, the second motor 20 rotates. The second motor 20 can provide power for the sliding sleeve 28 through the tooth column 21. Due to the locking function of the prism 23, the core column 16 cannot rotate at this time. The sliding sleeve 28 slides in the spiral groove 26 through the sliding edges thereon, that is, the sliding sleeve 28 rotates and moves towards the direction of the prism 23. The sliding sleeve 28 pushes the sliding plate 24 to move synchronously through the fourth connecting plate 27, so as to pull the prism 23 out of the rhombic jack, which is convenient for providing power for the prism 23. At this time, the fourth connecting plate 27 rotates relative to the sliding sleeve 28. When the prism 23 stops the locking work, the tooth column 21 can drive the core column 16 to rotate through the sliding sleeve 28, so as to adjust the position of the pressing plate.

[0051] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
