Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically a special pulverizing and mixing device for pharmaceutical testing. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN219328656U, published on July 11, 2023, which discloses a dedicated pulverizing and mixing device for drug testing. The device includes a drug testing pulverizing tank, a first motor, and a drug inlet. The first motor is fixedly connected to the top of the pulverizing tank, and pulverizing blades are fixedly connected to the output end of the first motor. The drug inlet is fixedly connected to the top of the pulverizing tank, and a filter screen is fixedly connected inside the pulverizing tank, arranged horizontally. A guide pipe is fixedly connected to the bottom of the pulverizing tank, and a first manual valve is installed outside the guide pipe. The advantages of this invention are: this device integrates drug pulverization and drug-liquid mixing into one unit. This device eliminates the need to transfer the pulverized drug powder; instead, it directly adds it to the drug testing mixing tank. This high degree of integration allows the pulverized drug powder to be directly mixed and stirred with the liquid within a closed space, i.e., the drug testing mixing tank, resulting in a highly pure and uncontaminated sample solution.

[0003] However, the device also has the following drawbacks: the filter screen can block the tablets and crush them with the crushing blades. However, in actual use, the filter screen is prone to becoming a point of accumulation for the crushed tablets, leading to frequent blockages. Excessive accumulation of tablets will affect the smooth flow of the liquid medicine and further affect the mixing efficiency of the subsequent liquid medicine. Utility Model Content

The first motor 31 is a servo reduction motor, which can accurately control the rotation speed and rotation angle of the output shaft. The first motor 31 is electrically connected to an external power supply and is controlled by an external program. A rotating disk 33 is fixedly connected to the surface of the output shaft of the first motor 31. A transmission shaft 34 is fixedly connected to the front of the rotating disk 33. Limiting blocks 35 are fixedly connected to the front of both fixed bars 32. Sliding rods 36 are slidably connected to the inner walls of both limiting blocks 35.

A filter screen layer 39 is fixedly connected between the front of the two connecting bars 37. The transmission shaft 34 and the connecting frame bars 38 are compatible. By setting the vibration filtering mechanism 3, the filter screen layer 39 can be driven to perform continuous reciprocating motion, so that it can vibrate and filter the tablet particles, allowing them to smoothly enter the mixing tank 8, reducing the possibility of clogging and extending the service life of the filter screen.

[0018] A fixing plate 4 is fixedly connected to the front of the support frame 2, and a feeding bin 5 is fixedly connected to the front of the fixing plate 4. A crushing mechanism 6 is provided on the feeding bin 5. By setting the crushing mechanism 6, the first gear 65 can drive the two second gears 66 to rotate, and the two crushing wheels 67 can be precisely controlled to rotate relative to each other, so as to precisely control the crushing speed and allow the material to be fully crushed.

[0019] The crushing mechanism 6 includes a base 61 fixedly connected to the right side of the feeding bin 5, multiple guide plates 62 fixedly connected to the feeding bin 5, and two rotating shafts 63 rotatably connected to the inner wall of the feeding bin 5. A second motor 64 is fixedly connected to the base 61. The second motor 64 is a servo geared motor, which can precisely control the rotation speed and rotation angle of the output shaft. The second motor 64 is electrically connected to an external power supply and is controlled by an external program. A first gear 65 is fixedly connected to the surface of the output shaft of the second motor 64. A second gear 66 and a crushing wheel 67 are fixedly connected to the surfaces of the two rotating shafts 63.

[0020] Four support columns 7 are fixedly connected to the top of the base 1, and a mixing tank 8 is fixedly connected to the top of the four support columns 7. A discharge faucet 9 is provided on the surface of the mixing tank 8.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] The working principle of this utility model is as follows: First, different pharmaceutical raw materials are put into the feeding hopper 5 and the second motor 64 is started, which drives the first gear 65 to rotate through the output shaft. When the first gear 65 rotates, it drives the front second gear 66, which rotates through the front rotating shaft 63 inside the feeding hopper 5. When the front second gear 66 rotates, it drives the rear second gear 66 to rotate in reverse through the rear rotating shaft 63 inside the feeding hopper 5. The two rotating shafts 63 rotate relative to each other, driving the two crushing wheels 67 to rotate synchronously relative to each other, thus crushing the pharmaceutical raw materials. Then, the first motor 31 is started, which drives the rotating disk 33 to rotate through the output shaft. The rotating disk 33 rotates... The transmission shaft 34 squeezes and drives the connecting frame strip 38, causing the connecting frame strip 38 and the two connecting strips 37 to reciprocate in the left and right directions between the inner walls of the two limiting blocks 35 via the two sliding rods 36. When the two connecting strips 37 move, they drive the filter screen layer 39 to reciprocate synchronously. When the filter screen layer 39 moves, it vibrates and filters the falling medicine liquid. Then the material falls into the mixing tank 8. Then the third motor 10 is started, which drives the stirring shaft 11 at the output end to rotate. When the stirring shaft 11 rotates, it drives multiple stirring rods 12 to rotate and stir the material, mixing their medicine liquid. Finally, the discharge faucet 9 is opened, and the discharged medicine liquid is collected in a container and tested.
