Description

Technical Field

[0001] This utility model relates to a gyratory granulator, specifically a gyratory granulator for pharmaceutical production, and belongs to the technical field of gyratory granulator. Background Technology

[0002] A gyratory pellet mill is a type of pellet mill that uses the gyratory action of a rotating drum to granulate solid materials. In tablet production, it utilizes the extrusion principle to force soft materials with suitable moisture content through a sieve of a specific mesh size, achieving the purpose of pelleting and thus facilitating the next step of tablet production. It is widely used in the pharmaceutical and chemical industries.

[0003] Utility model patent CN210229879U discloses a gyratory granulator for pharmaceutical production, comprising a gyratory granulator body, a machine casing, a support frame, a screen, and a rotating drum. A discharge hood is fixedly installed at the top of the support frame. This utility model, a gyratory granulator for pharmaceutical production, uses a hot air blower to dry the granules passing through the discharge cylinder, maximizing the removal of moisture from the granules during their fall, thereby improving granulation effect and quality.

[0004] In pharmaceutical production, pulverizing is necessary to improve tableting efficiency. While the granulator in the aforementioned patent removes moisture from the granules to the greatest extent possible, the screen is typically made of metal. Due to the open holes, the metal plate has low strength, and under long-term compression during processing, the surface easily becomes uneven, resulting in reduced granulation efficiency. Therefore, we provide a swing-type granulator for pharmaceutical production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a swing-type granulator for pharmaceutical production to solve the above-mentioned problems, thereby addressing the issue of uneven surfaces on metal screens after prolonged use as described in the prior art.

[0006] This utility model is achieved through the following technical solution: a swing-type granulator for pharmaceutical production.

[0007] The device includes a drive body, a granulation box fixedly connected to the surface of the drive body, a granulation mechanism inside the granulation box, a screen that engages with the drive body, and a shaping mechanism outside the granulation box. The shaping mechanism includes a connecting frame, a scraper, and a shaping roller, with both ends of the scraper fixedly connected to the connecting frame.

[0008] Preferably, the granulation box is fitted with a gathering cover, which is fixedly connected to the drive body. The gathering cover is made of plastic. A loading box is provided directly below the granulation box. The granulation box gathers and collects the aminobenzoic acid particles delivered from the granulation box and transports them into the loading box.

[0009] Preferably, the granulation box is fixedly connected with a buckle, and the top of the screen is engaged with the buckle. The granulation box is slidably connected with a positioning frame for limiting the screen. A rotating wheel is rotatably connected to the middle of the positioning frame. The positioning frame fixes the rotating wheel and the two sides of the screen, thereby improving the stability of the screen granulation.

[0010] Preferably, the rotating wheel is slidably connected to the screen, and a linkage shaft is inserted inside the rotating wheel. One end of the linkage shaft is rotatably connected to the granulation box, and the other end of the linkage shaft is assembled and connected to the output end of the granulation box. By rotating the rotating wheel back and forth, the aminobenzoic acid material inside the screen is sheared and squeezed, so that the aminobenzoic acid material is squeezed out through the holes of the screen to complete the aminobenzoic acid granulation operation.

[0011] Preferably, a fixed sleeve and an arc-shaped rail are fixedly connected to the surface of the granulation box. One end of the connecting frame is rotatably connected to the fixed sleeve, and the other end of the connecting frame is slidably connected to the arc-shaped rail. The fixed sleeve and the arc-shaped rail are used to position the two ends of the connecting frame, thereby improving the stability of the connecting frame's rotation.

[0012] Preferably, a first electric push rod is rotatably connected to the surface of the driving body, and the output end of the first electric push rod is rotatably connected to the connecting frame. A lifting frame is rotatably connected to the surface of the shaping roller. The connecting frame is rotated and moved by the first electric push rod, so that the connecting frame swings back and forth along the arc of the screen.

[0013] Preferably, a sliding rod is fixedly connected to the surface of the lifting frame, and the sliding rod is slidably connected to the connecting frame. A second electric push rod is fixedly connected to the middle of the connecting frame, and the output end of the second electric push rod is fixedly connected to the lifting frame. The second electric push rod provides thrust to the lifting frame, causing the lifting frame to drive the shaping roller to contact the screen.

[0014] This utility model provides a swing-type granulator for pharmaceutical production, which has the following beneficial effects:

[0015] 1. This pharmaceutical production uses a swing-type granulator. The rotating wheel compresses the tranexamic acid material on the screen surface, thereby granulating the tranexamic acid drug. The connecting frame drives the scraper to move and scrape off the residual tranexamic acid particles on the screen surface, preventing the tranexamic acid particles from remaining on the screen surface and causing screen blockage. The connecting frame drives the shaping roller to roll along the screen, compressing the screen and flattening the outward protrusions of the screen, making the contact between the screen and the rotating wheel tighter and improving the granulation efficiency of the tranexamic acid drug.

[0016] 2. This pharmaceutical production uses a swing-type granulator. A gathering hood collects and gathers the tranexamic acid granules from the granulation chamber, then transports them into the loading chamber, improving tranexamic acid granule production efficiency. A snap-lock mechanism provides initial positioning of the screen, facilitating screen replacement in case of damage. A positioning frame secures the rotating wheels and both sides of the screen, improving granulation stability. The reciprocating rotation of the wheels shears and compresses the tranexamic acid material inside the screen, forcing it through the screen's openings. The process begins with the granulation of aminobenzoic acid. The granulation box controls the rotation of the linkage shaft, which in turn drives the rotating wheel. A fixed sleeve and arc-shaped rail position both ends of the connecting frame, improving its rotational stability. A first electric push rod controls the connecting frame's rotation and movement, causing it to oscillate back and forth along the screen's arc. A sliding rod fixes the lifting frame, which in turn moves the shaping roller, bringing it into contact with the screen surface to shape the screen. A second electric push rod provides thrust to the lifting frame, causing it to move the shaping roller into contact with the screen. Attached Figure Description

The gathering cover 3 is made of plastic. A carrying box 4 is set directly below the granulation box 2. The tranexamic acid particles conveyed from the granulation box 2 are gathered and collected through the gathering cover 3 and transported to the inside of the carrying box 4, thereby improving the production efficiency of tranexamic acid particles. The gathering cover 3 is made of transparent material, which facilitates the observation of the internal condition of the gathering cover 3.

[0028] The drive unit 1 is the power unit of the swing pellet mill. The internal transmission method and power source are existing equipment. This application will not go into detail about its detailed parameters and model.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The granulation box 2 is equipped with a granulation mechanism 5, which includes a screen 501 that is engaged with the drive body 1. The tranexamic acid material on the surface of the screen 501 is squeezed by the rotation of the rotating wheel 503, thereby granulating the tranexamic acid drug.

[0030] The granulation box 2 is fixedly connected with a buckle 502, and the top of the screen 501 is engaged with the buckle 502. The granulation box 2 is slidably connected with a positioning frame 505 for limiting the screen 501. A rotating wheel 503 is rotatably connected to the middle of the positioning frame 505. The buckle 502 is used to initially position the screen 501, which is convenient for replacing the screen 501 when it is damaged. The positioning frame 505 is used to fix the rotating wheel 503 and the two sides of the screen 501, which improves the stability of the granulation of the screen 501. The rotating wheel 503 reciprocates to shear and squeeze the tranexamic acid material inside the screen 501, so that the tranexamic acid material is squeezed out through the holes of the screen 501, thus completing the tranexamic acid granulation operation.

[0031] The rotating wheel 503 is slidably connected to the screen 501. A linkage shaft 504 is inserted inside the rotating wheel 503. One end of the linkage shaft 504 is rotatably connected to the granulation box 2, and the other end of the linkage shaft 504 is assembled and connected to the output end of the granulation box 2. The linkage shaft 504 is controlled to rotate by the driving body 1, so that the linkage shaft 504 drives the rotating wheel 503 to rotate.

[0032] Please refer to it again. Figure 2 and Figure 5 The granulation box 2 is equipped with a shaping mechanism 6 on its exterior. The shaping mechanism 6 includes a connecting frame 601, a scraper 605, and a shaping roller 608. The two ends of the scraper 605 are fixedly connected to the connecting frame 601. The connecting frame 601 drives the scraper 605 to move, scraping off the tranexamic acid particles remaining on the surface of the screen 501, thus preventing the tranexamic acid particles from remaining on the surface of the screen 501 and causing the screen 501 to become clogged. The connecting frame 601 drives the shaping roller 608 to roll along the screen 501, squeezing the screen 501 and flattening the outward protrusions of the screen 501, making the screen 501 contact more tightly with the rotating wheel 503, and improving the production efficiency of tranexamic acid granules.

[0033] The surface of the granulation box 2 is fixedly connected with a fixed sleeve 602 and an arc-shaped rail 603. One end of the connecting frame 601 is rotatably connected to the fixed sleeve 602, and the other end of the connecting frame 601 is slidably connected to the arc-shaped rail 603. The fixed sleeve 602 and the arc-shaped rail 603 are used to position the two ends of the connecting frame 601, thereby improving the stability of the rotation of the connecting frame 601.

[0034] The surface of the driving body 1 is rotatably connected to a first electric push rod 604, and the output end of the first electric push rod 604 is rotatably connected to the connecting frame 601. The first electric push rod 604 controls the rotation and movement of the connecting frame 601, causing the connecting frame 601 to swing back and forth along the arc of the screen 501.

[0035] A lifting frame 609 is rotatably connected to the surface of the shaping roller 608. A sliding rod 606 is fixedly connected to the surface of the lifting frame 609, and the sliding rod 606 is slidably connected to the connecting frame 601. The lifting frame 609 is fixed by the sliding rod 606, and the shaping roller 608 is moved by the lifting frame 609, so that the shaping roller 608 comes into contact with the surface of the screen 501 and shapes the screen 501.

[0036] A second electric push rod 607 is fixedly connected to the middle of the connecting frame 601, and the output end of the second electric push rod 607 is fixedly connected to the lifting frame 609. The second electric push rod 607 provides a thrust to the lifting frame 609, so that the lifting frame 609 drives the shaping roller 608 to contact the screen 501.

[0037] The first electric actuator 604 and the second electric actuator 607 are existing devices, and their detailed parameters and models will not be described in detail in this application.

[0038] Working principle: Tranexamic acid raw material is poured into the granulation box 2 through the feed inlet at the top of the granulation box 2. The drive body 1 controls the rotation of the linkage shaft 504, which in turn drives the rotating wheel 503 to rotate. The reciprocating rotation of the rotating wheel 503 shears and squeezes the tranexamic acid material inside the screen 501, forcing the tranexamic acid material out through the holes of the screen 501, thus completing the tranexamic acid granulation operation. The tranexamic acid granules conveyed from the granulation box 2 are gathered and collected by the collecting hood 3 and transported to the carrying box 4, improving the production efficiency of tranexamic acid granules. After the tranexamic acid granulation is completed, the first electric push rod 604 controls the... The connecting frame 601 rotates and moves, causing it to swing back and forth along the arc of the screen 501. The connecting frame 601 drives the scraper 605 to move, scraping away the residual para-aminobenzoic acid particles on the surface of the screen 501. When the through holes of the screen 501 deform, the second electric push rod 607 provides a thrust to the lifting frame 609, causing the lifting frame 609 to drive the shaping roller 608 to contact the screen 501. The connecting frame 601 drives the shaping roller 608 to roll along the screen 501, squeezing the screen 501 and flattening the outward protrusions of the screen 501. This makes the contact between the screen 501 and the rotating wheel 503 tighter, improving the efficiency of para-aminobenzoic acid granulation.
