[0003] However, during long-term use, especially when processing sticky or easily adhered materials, drug residues often remain on the screening screen of such equipment. This not only affects screening efficiency but may also jeopardize product quality and patient safety due to cross-contamination of drugs. In traditional integrated pulverizing and screening machines, the screening screen is often fixed to the machine body by bolts, welding, or direct embedding. While this design is sturdy, it brings great inconvenience to the cleaning and maintenance of the screening screen. Each time the screening screen is cleaned or replaced, a lot of time is required to disassemble surrounding parts, and it may even require the entire machine to be shut down.
[0004] Therefore, we propose a novel integrated crushing and screening machine for pharmaceutical processing. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-6 As shown, a pharmaceutical processing pulverizing and sieving integrated machine includes a machine body 1. The upper end of the machine body 1 has a through-feed hole. A pulverizing motor 4 is fixedly connected to the upper end of the machine body 1 and is arranged vertically downward. The output end of the pulverizing motor 4 is connected to a rotating rod 5 through a flange. The bottom end of the rotating rod 5 is fixedly connected to a connecting rod 12. Both ends of the connecting rod 12 are rotatably connected to pulverizing rollers 6. A sieving component 2 is provided below the pulverizing rollers 6. A rotating component is provided inside the machine body 1 to rotate the pulverizing rollers 6. The sieving component 2 penetrates the side wall of the machine body 1. A connecting arc plate 11 is fixedly connected to the outer side wall of the sieving component 2. A sealing plate 3 is fixedly connected to the outer side wall of the connecting arc plate 11. The sealing plate 3 and the machine body 1 are connected by two snap-fit components. Multiple supports 10 are fixedly connected to the outer side wall of the machine body 1. A collecting component is provided below the machine body 1.
[0025] In an optional embodiment: the screening component 2 includes a wire frame 21, a partition plate 22 and two screening screens 23. The wire frame 21 is fixedly connected to the side wall of the connecting arc plate 11, the partition plate 22 is fixedly connected to the inner side wall of the wire frame 21, and the two screening screens 23 are respectively fixedly connected to the side wall between the wire frame 21 and the partition plate 22. The mesh diameters of the two screening screens 23 are different.
[0026] It should be noted that the crushed medicine should be sieved according to the size of the crushed particles to prevent large particles from remaining on the sieve and causing jamming later.
[0027] In an optional embodiment: the rotating component includes a groove 7, which is formed inside the body 1. An annular toothed plate 8 is fixedly connected to the bottom side wall of the groove 7. Two gears 9 are meshed on the annular toothed plate 8, and the two gears 9 are respectively fixedly connected to one end of the two crushing rollers 6.
[0028] It should be noted that, under the action of gear 9 and annular toothed plate 8, the crushing roller 6 can be kept rotating even when the medicine is spread on the sieve 2, thereby improving the crushing effect of the crushing roller 6.
[0029] In an optional embodiment: each snap-fit component includes a locking plate 17, which is fixedly connected to the outer side wall of the body 1. A limit rod 18 is hinged to the upper end of the locking plate 17. The longitudinal section of the limit rod 18 is L-shaped. A second locking plate 19 is fixedly connected to the outer side wall of the sealing plate 3.
[0030] It should be noted that by rotating the limiting rod 18 upward, the limiting rod 18 is separated from the locking plate 19, thus releasing the restriction on the locking plate 19. This allows the sealing plate 3 to be pulled outward, thereby removing the screening component 2 from the machine body 1 for replacement or cleaning.
[0031] In an optional embodiment: the collecting component includes a powder collecting cylinder 15, which is located directly below the body 1, and a partition plate 151 is fixedly connected to the inner side wall of the powder collecting cylinder 15.
[0032] In an optional embodiment: a plurality of crushing cones 13 are fixedly connected to the side wall of the crushing roller 6, and a scraper 14 is fixedly connected to the side wall of the connecting rod 12. Through the mutual cooperation of the crushing cones 13 on the crushing roller 6 and the scraper 14 installed on the connecting rod 12, the crushing of the medicine is accelerated and the accumulated powder is scraped through two screening screens 23, thereby helping to improve the screening of the size of the medicine.
[0033] In an optional embodiment: the machine body 1 is provided with a sealing door 16. The sealing door 16 is opened, and the crushing roller 6 is taken out from the through hole at the sealing door 16 for cleaning.
[0034] In practical use, the working principle of this utility model is as follows:
[0035] Drug pulverization and sieving:
[0036] The medicine is gradually fed into the machine body 1 through the feeding hole, and the medicine is scattered on the screening piece 2. Then the crushing motor 4 is started. The output end of the crushing motor 4 rotates, which drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 causes the connecting rod 12 to rotate around the rotating rod 5 as the axis, which in turn causes the two crushing rollers 6 to move in a circular motion, thereby crushing the medicine on the screening piece 2. Through the cooperation of the crushing cone 13 on the crushing roller 6 and the scraper 14 installed on the connecting rod 12, the crushing of the medicine is accelerated and the accumulated powder is scraped through the two screening screens 23, thereby completing the screening of the medicine size. Since the gear 9 installed on one side of the crushing roller 6 is meshed with the annular toothed plate 8, when the crushing roller 6 is moving in a circular motion, under the action of the gear 9 and the annular toothed plate 8, the crushing roller 6 can be kept rotating even when the medicine is spread flat on the screening piece 2, thus improving the crushing effect of the crushing roller 6.
[0037] Disassembly of the screening screen:
[0038] By rotating the limiting rod 18 upwards, the limiting rod 18 is separated from the locking plate 19, thus releasing the restriction on the locking plate 19. This allows the sealing plate 3 to be pulled outwards, thereby removing the sieve 2 from the machine body 1 for replacement or cleaning. Conversely, the sieve 2 is inserted into the machine body 1, and then the limiting rod 18 is rotated in the opposite direction, so that one end of the limiting rod 18 contacts the side wall of the locking plate 19, restricting the position of the locking plate 19. This fixes the sealing plate 3 to the side wall of the machine body 1. The rotating rod 5 is connected to the output end of the pulverizing motor 4 through the flange. Drug residue will also remain on the pulverizing roller 6. Therefore, the pulverizing roller 6 can be removed simply by opening the flange, opening the sealing door 16, and removing the pulverizing roller 6 from the through hole at the sealing door 16.
[0039] When the powder collection cylinder 15 is placed, the positions of the second partition plate 151 on it correspond to those of the first partition plate 22.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
