Technical Field

[0001] The utility model relates to the technical field of drug manufacturing, and more specifically to a synchronous feeding device for multiple drugs used in the preparation of compound drugs. Background Art

[0002] Equipment used in the production process of compound drugs needs to use a loading device to synchronously transport different types of drug raw materials to downstream production equipment (such as a mixing barrel used to mix multiple drugs).

[0003] However, when loading, the existing feeding devices directly transport different drug powders to the drug mixing barrel for mixing at the same time. The drugs enter the mixing barrel and accumulate, and then the mixing barrel mixes the accumulated drugs, which makes the uniformity and mixing efficiency of the drugs mixed in the drug mixing barrel easily affected.

The main shaft end of the motor is fixedly connected to a transmission disk. The outer wall of the outer shell is provided with a transmission groove connected to its interior. The outer wall of the transmission disk passes through the transmission groove and abuts against the outer wall of the limit ring. Different drugs enter the confluence pipe from the feed pipe, and then enter the top of the sieve plate from the confluence pipe. The sieve plate starts to rotate by itself under the operation of the motor and generates vibration during the rotation, thereby evenly sifting the drugs from the sieve plate, so that the drugs are evenly spread in the drug mixing barrel after being sifted from the sieve plate, thereby achieving the increase of uniformity and efficiency of mixing drugs in the drug mixing barrel during the synchronous feeding process of the drugs.

[0006] Preferably, a rubber ring is fixedly connected to the top of the fixing ring, and the bottom of the linkage block abuts against the top of the rubber ring under its own gravity; by providing the rubber ring, the collision between the linkage block and the fixing ring can be buffered, thereby increasing the service life of both.

[0007] Preferably, a material discharge box connected to the interior of the confluence pipe is fixedly connected to the top inner wall of the outer shell, and a material discharge trough connected to the interior of the confluence pipe is provided at the bottom of the material discharge box; through the provided material discharge box, after the medicine enters the material discharge box, it falls from the material discharge trough to the sieve plate, and as the sieve plate rotates, the uniformity of the medicine falling on the sieve plate is increased, thereby increasing the uniformity of the medicine sieved off the sieve plate.

[0008] Preferably, the inner wall at the bottom of the material box is fixedly connected with symmetrically arranged guide plates, and the guide plates are inclined toward the material trough; the guide plates are arranged to guide the medicine entering the material box, thereby preventing the medicine from accumulating and clogging in the material box.

[0009] Preferably, a retaining ring for covering the sieve plate is fixedly connected to the top of the fixing ring; by providing the retaining ring, the retaining ring covers the medicine on the sieve plate, thereby preventing the medicine from leaking from the sieve plate.

[0010] Preferably, the bottoms of both ends of the linkage block are arc-shaped; the arc-shaped setting of the bottom of the linkage block allows the arc-shaped part of the linkage block to contact and fit with the guide rod when the linkage block contacts the guide rod, thereby preventing excessive wear of both and increasing the service life of both.

[0012] 1. The utility model is provided with a confluence pipe, a feed pipe, a limit ring, a slide groove, a fixed ring, a slide rod, a sieve plate, a guide rod, and a linkage block. Different drugs are allowed to enter the confluence pipe from the feed pipe and then enter the top of the sieve plate from the confluence pipe. The sieve plate starts to rotate by itself under the operation of the motor and generates vibrations during the rotation, so that the drugs are evenly sifted from the sieve plate, so that the drugs are evenly spread in the drug mixing barrel after being sifted from the sieve plate, thereby achieving the increase of the uniformity and efficiency of the drugs mixed in the drug mixing barrel during the process of synchronous drug feeding.

[0013] 2. The outer edge of the sieve plate in the utility model gradually bulges toward the middle, so that when the medicine falls on the sieve plate, as the sieve plate shakes, the medicine can slide around along the sieve plate, which increases the effect of evenly spreading the medicine on the sieve plate and prevents the medicine from accumulating on the sieve plate and clogging the sieve plate.

The outer wall of the fixed ring 6 is fixedly connected with a plurality of linkage blocks 10, the outer wall of the shell 1 is fixedly connected with a motor 11, the main shaft end of the motor 11 is fixedly connected with a transmission disk 12, the outer wall of the shell 1 is provided with a transmission groove 13 connected with the interior thereof, the outer wall of the transmission disk 12 passes through the transmission groove 13 and abuts against the outer wall of the limit ring 4; different drugs enter the confluence pipe 2 from the feed pipe 3, and then enter the top of the sieve plate 8 from the confluence pipe 2, the sieve plate 8 starts to rotate by itself under the operation of the motor 11, and vibrates during the rotation process, so that the drugs are evenly screened from the sieve plate 8, so that the drugs are evenly spread in the drug mixing barrel after being screened from the sieve plate 8, thereby realizing the increase of the uniformity and efficiency of the drugs mixed in the drug mixing barrel during the synchronous feeding process of the drugs.

[0022] Furthermore, a rubber ring 14 is fixedly connected to the top of the fixing ring 6, and the bottom of the linkage block 10 abuts against the top of the rubber ring 14 under its own gravity; by providing the rubber ring 14, the collision between the linkage block 10 and the fixing ring 6 can be buffered, thereby increasing the service life of both.

[0023] Furthermore, a material discharge box 15 connected to the interior of the confluence pipe 2 is fixedly connected to the top inner wall of the outer shell 1, and a material discharge trough 16 connected to the interior of the material discharge box 15 is provided at the bottom; through the setting of the material discharge box 15, after the medicine enters the material discharge box 15, it falls from the material discharge trough 16 to the sieve plate 8, and as the sieve plate 8 rotates, the uniformity of the medicine falling on the sieve plate 8 is increased, thereby increasing the uniformity of the medicine sieved by the sieve plate 8.

[0026] Furthermore, the bottoms of both ends of the linkage block 10 are both arc-shaped; the arc-shaped setting of the bottom of the linkage block 10 allows the arc-shaped part of the linkage block 10 to contact and fit with the guide rod 9 when the linkage block 10 contacts the guide rod 9, thereby preventing excessive wear of the two and increasing the service life of the two.

[0027] Working principle: This embodiment provides a device for synchronously feeding multiple drugs for preparing compound drugs. When in use, the housing 1 is placed on the drug mixing barrel that needs to synchronously deliver the drugs, and the different drugs are delivered from the multiple feeding pipes 3 to the confluence pipe 2 through the powder delivery pump in the prior art. The drugs entering the confluence pipe 2 will then enter the discharge pipe, and fall onto the sieve plate 8 after passing through the discharge trough 16 at the bottom of the discharge pipe;

[0028] The rotation of the motor 11 drives the transmission plate 12 to rotate, and the rotation of the transmission plate 12 drives the limit ring 4 to rotate through the friction force, and the limit ring 4 clamps the slide bar 7 through the slide groove 5 to drive the fixed ring 6 to rotate together. It should be noted that although the limit ring 4 can clamp the slide bar 7 through the slide groove 5 to drive the fixed ring 6 to rotate, the fixed ring 6 can still drive the slide bar 7 to move up and down automatically;

[0029] As the fixing ring 6 rotates, the multiple linkage blocks 10 fixed on the outer wall of the fixing ring 6 will contact the guide rod 9, and after being blocked by the inclined guide rod 9, they will gradually move upward along the outer wall of the guide rod 9, so that the linkage block 10 drives the fixing ring 6 to move upward, and as the linkage block 10 continues to move, after the bottom of the linkage block 10 is no longer in contact with the guide rod 9, the linkage block 10 and the fixing ring 6 will begin to fall downward under their own gravity, thereby hitting the rubber ring 14 on the limit ring 4, so that the fixing ring 6 vibrates, and the screen plate 8 is fixed. It is connected to the inner wall of the fixed ring 6, so the sieve plate 8 will vibrate synchronously and circulate in this way, so that the sieve plate 8 will vibrate and sieve the medicine into the medicine mixing barrel, and the outer edge of the sieve plate 8 gradually bulges toward the middle, so that when the medicine falls on the sieve plate 8, as the sieve plate 8 shakes, the medicine can slide around along the sieve plate 8, while increasing the effect of the sieve plate 8 to evenly spread the medicine, it can also prevent the medicine from accumulating on the sieve plate 8 and clogging the sieve plate 8, thereby achieving the increase in the uniformity and efficiency of mixing the medicine in the medicine mixing barrel during the synchronous feeding process of the medicine.
