Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] like Figures 1 to 6 As shown, this utility model provides a drug uniform swaying granulation device, whose main components include a machine body 1. A swaying granulator assembly 2 is fixedly connected to the front of the machine body 1. This assembly is responsible for processing the drug raw materials. A control panel 3 is fixedly connected to the upper right side of the machine body 1. The control panel 3 is used to control the operation of the entire device, including start and stop. The swaying granulator assembly 2 consists of a shell, a granulation chamber, a vibration mechanism, and a screen. The granulation chamber is the core part for manufacturing granules and is usually composed of a cylindrical container. The raw materials are subjected to swaying motion in the granulation chamber, thereby forming granules. The vibration mechanism is the component that drives the swaying motion of the granulation chamber. It is usually composed of a motor, a reducer, and a swing arm, which enables the granulation chamber to sway in both horizontal and vertical directions. A screen is usually provided at the bottom of the granulation chamber to control the size of the granules. As needed, screens with different apertures can be replaced to obtain granules of the desired size. Since the specific working principle of the swaying granulator assembly 2 is prior art, it will not be described in detail here.
[0034] Preferably, the upper surface of the oscillating granulator assembly 2 is provided with a feed inlet, and a feed hopper 4 is fixedly installed on the inner wall of the feed inlet for feeding the drug raw materials into the device; similarly, the lower surface of the oscillating granulator assembly 2 is provided with a discharge outlet, and a discharge hopper 5 is fixedly installed on the inner wall of the discharge outlet for discharging the processed granulated drug; a mounting frame 6 is fixedly connected to the upper surface of the feed hopper 4, and the main function of the mounting frame 6 is to provide a fixed and supportive platform for installing other components; a baffle assembly 61 is provided on the upper inner wall of the mounting frame 6, and the baffle assembly 61 can play a protective role during drug processing.
[0035] Specifically, the material blocking assembly 61 includes a baffle 611, the outer surface of which is fixedly connected to the inner wall of the mounting frame 6. A sliding groove with front and rear connections is provided on the front of the baffle 611. A baffle 612 for blocking material is slidably connected inside the sliding groove. An anti-detachment block 613 is fixedly connected to the left side of both the upper and lower surfaces of the baffle 612, so that the baffle 612 slides stably in the sliding groove without falling off. The lower length of the outer surface of the baffle 611 is less than its upper length. In addition, a scraper 614 is fixedly connected to the lower right side of the outer surface of the baffle 611. The baffle 612 will contact the scraper 614 during the sliding process. The scraper 614 can scrape off the dust or residual medicine attached to the baffle 612 and keep it clean. A placement groove is provided on the right side of the upper surface of the mounting frame 6. The lower surface of the inner wall of the placement groove in the mounting frame 6 overlaps with the lower surface of the baffle 612.
[0036] Meanwhile, a locking component 7 is provided at the upper center of the right side of the mounting frame 6 in this embodiment. The locking component 7 specifically includes a blocking block 71 and a fixing shaft 73. A vertical groove 72 is provided on the front of the blocking block 71, and the interior of the vertical groove 72 is slidably connected to the outer surface of the fixing shaft 73. The end face of the fixing shaft 73 is fixedly connected to the surface of the mounting frame 6 to ensure its stability. An anti-detachment block 74 is also fixedly connected above the outer surface of the fixing shaft 73. The length of the anti-detachment block 74 is greater than the width of the vertical groove 72 to prevent the blocking block 71 from falling off the fixing shaft 73.
[0037] To further improve the locking effect, a limiting groove 75 with internal and external communication is provided on the lower surface of the inner wall of the vertical groove 72. A T-shaped block 76 for blocking is overlapped inside the limiting groove 75, and the surface of the T-shaped block 76 is fixedly connected to the surface of the mounting frame 6. When the blocking block 71 slides to contact the T-shaped block 76, the T-shaped block 76 can limit the further movement of the blocking block 71, so that the blocking block 71 has two force points at the top and bottom at the same time to improve stability, thereby ensuring the stability of the locking assembly 7. In addition, arc-shaped grooves 77 are provided on the lower left and right sides of the blocking block 71. The left and right arc-shaped grooves 77 are mirrored. A rubber block 78 for clamping is overlapped and pressed against the inner wall of the arc-shaped groove 77, and the outer surface of the rubber block 78 is fixedly connected to the surface of the mounting frame 6. When the blocking block 71 slides to contact the rubber block 78, the rubber block 78 can elastically deform and clamp the blocking block 71, further improving the locking effect. At the same time, the left and right rubber blocks 78 are in a contracted state. When the lower left and right sides of the blocking block 71 contact the rubber block 78, they can be squeezed and deformed, thus clamping the blocking block 71 more tightly. When it is necessary to release the locking assembly 7, simply pull the blocking block 71 upward to disengage the blocking block 71 from the T-shaped block 76 and the rubber block 78, and then rotate the blocking block 71 180° to separate the blocking block 71 from the mounting frame 6. At this time, the second baffle 612 can be slid open. When it is necessary to lock the second baffle 612, simply rotate the blocking block 71 again and push the blocking block 71 downward to make the blocking block 71 contact the mounting frame 6, the T-shaped block 76 and the rubber block 78 respectively, thereby locking the second baffle 612.
[0038] In this embodiment, two rotating shafts 602 are movably connected to the lower inner wall of the mounting frame 6. Gears 604 are fixedly connected to the rear outer surface of both the left and right rotating shafts 602. The two gears 604 mesh with each other, and when one rotating shaft 602 rotates, it drives the other rotating shaft 602 to rotate synchronously. Crushing rollers are fixedly fitted onto the outer surfaces of both rotating shafts 602 for crushing clumps of medicine. A cam 603 is fixedly connected to the front and rear outer surfaces of the right rotating shaft 602. When the rotating shaft 602 rotates, the cam 603 also rotates accordingly. A motor 601 is fixedly connected to the lower front of the mounting frame 6. The output shaft of the motor 601 passes through the mounting frame 6 and is fixedly connected to the right rotating shaft 602 via a coupling. When the motor 601 starts, it drives the right rotating shaft 602 and its cam 603 to rotate. The outer surfaces of the front and rear cams 603 are fitted with... A screen plate 606 is connected to the inner wall of the mounting frame 6. The end of the screen plate 606 away from the cam 603 is movably connected to the inner wall of the mounting frame 6. The outer surface of the rotating shaft at the front and rear movable parts of the screen plate 606 is fitted with a return spring 6061. The two ends of the return spring 6061 are fixedly connected to the surface of the screen plate 606 and the mounting frame 6, respectively. The return spring 6061 enables the screen plate 606 to have a reset function. In this embodiment, an inclined arc plate 605 is fixedly connected to the inner wall of the mounting frame 6 away from the screen plate 606. The front and rear sides of the inclined arc plate 605 are tightly fitted and fixed to the inner wall of the mounting frame 6. The inclined arc plate 605 and the screen plate 606 form a V-shaped structure. The ends of the inclined arc plate 605 and the screen plate 606 that are close to each other form a material inlet channel. The screen plate 606 can screen out larger dry drug materials and guide these larger dry drug materials to fall to the middle position of the two crushing rollers, thereby crushing the larger dry drug materials.
[0039] Working principle and usage process of this utility model:
[0040] When using the uniform swaying granulation device, first start the device via control panel 3, then pour the medicine into feed hopper 4, and then move baffle 2 612 to cover the mounting frame 6 to form a protective barrier, and lock baffle 2 612 via locking assembly 7; at the same time, motor 601 starts and drives the right rotating shaft 602 and its cam 603 to rotate, thereby driving the two crushing rollers to rotate, and the rotation of cam 603 causes the screen plate 606 to swing up and down, thereby accelerating the screening performance, so that larger lumps of medicine fall into the two crushing rollers for crushing, and then the crushed dry medicine material enters the swaying granulator assembly 2 through feed hopper 4 for granulation, and the processed medicine is discharged.
[0041] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model.
