Description

Technical Field

[0001] This utility model relates to the field of dry suspension production technology, specifically a grinding device for dry suspension production. Background Technology

[0002] Dry suspensions are liquid preparations made by mixing poorly soluble drugs with suitable excipients into powder or granules, which can be dispersed into a suspension by adding water and shaking before use for oral administration.

[0003] The existing Chinese patent publication number CN221789469U, entitled "A Dry Suspension Grinding Device," clearly states in its abstract that "this utility model, through the cooperation of the grinding box and the collection chamber structure, can transport some larger particles of dry suspension back into the inner cavity of the grinding box for further grinding. During the conveying process, it is in a closed state, which not only reduces the contact between the dry suspension and the staff or the outside world, thereby reducing the contamination of the dry suspension, but also makes the whole process automatic, thereby reducing the burden on the staff."

[0004] Because dry suspensions need to be ground to a certain particle size during grinding, and the required particle size varies under different circumstances, the existing technology cannot adjust the device according to the required particle size. This results in the inability to grind the dry suspension to the optimal particle size, leading to poor applicability. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for the production of dry suspensions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The top of the grinding box 1 is provided with a feeding port 11 for feeding. The bottom of the grinding box 1 is provided with a support box 13 for supporting the overall structure. The support box 13 has a sliding pull groove 14 inside, which is used to collect the ground dry suspension and pull it out directly after collection.

[0026] A first grinding roller 2 is installed at the rear of the grinding box 1. Slide grooves 22 are installed on both sides of the grinding box 1. Slide plates 23 are slidably installed inside the slide grooves 22. The slide plates 23 are locked inside the slide grooves 22 and slide. A second grinding roller 24 is installed on the inner side of the two slide plates 23. The first grinding roller 2 and the second grinding roller 24 are the main structure of the device and are used to grind the dry suspension. A first motor 21 is installed on one side of the outside of the grinding box 1. The drive shaft of the first motor 21 is connected to the first grinding roller 2. A second motor 25 is installed on the outer side of one slide plate 23. The drive shaft of the second motor 25 is connected to the second grinding roller 24. That is, the first motor 21 drives the first grinding roller 2 to rotate and the second motor 25 drives the second grinding roller 24 to rotate, thereby grinding the dry suspension.

[0027] An adjustment assembly is provided at the front of the grinding box 1. The adjustment assembly is used to adjust the distance between the second grinding roller 24 and the first grinding roller 2. The adjustment assembly includes a rotating shaft 4, which is rotatably mounted at the front of the grinding box 1. A third motor 42 is provided on one side of the rotating shaft 4, and the drive shaft of the third motor 42 is connected to the rotating shaft 4. Rotation ports 31 are provided on both sides of the front of the grinding box 1. Rotating components 32 are rotatably installed inside the rotation ports 31. The rotating components 32 are locked inside the rotation ports 31 and rotate. Worm gears 33 are provided on the outer side of the rotating components 32. Worms 41 are provided at both ends of the rotating shaft 4. Engaging with the worm gear 33, the rotating part 32 has a screw 34 inside, and a screw 3 is provided on one side of the slide plate 23. The screw 3 is fixedly installed, and the screw 34 is threadedly connected to the screw 3. That is, the rotating shaft 4 is driven to rotate by the third motor 42, and the worm gear 41 and worm wheel 33 are transmitted to make the two rotating parts 32 rotate simultaneously. Then, through the internal thread transmission, the two slide plates 23 move simultaneously, so as to adjust the distance between the second grinding roller 24 and the first grinding roller 2, thereby grinding dry suspensions of different particle sizes and increasing the applicability of the device.

[0028] Two slide plates 23 are equipped with mounting brackets 43 on their tops. The mounting brackets 43 are fixedly connected to the two slide plates 23.

The size of the feeding port 11 is adjusted by the first baffle 44 and the second baffle 45, that is, it is adjusted according to the position of the second grinding roller 24, so as to prevent the material from being thrown in front of the second grinding roller 24 when feeding.

[0029] The working principle of this utility model is as follows: Material is fed through the feeding port 11. The first motor 21 drives the first grinding roller 2 to rotate, and the second motor 25 drives the second grinding roller 24 to rotate, thereby grinding the dry suspension. The extraction groove 14 is used to collect the ground dry suspension. When it is necessary to grind dry suspensions of different particle sizes, the third motor 42 drives the rotating shaft 4 to rotate. Through the worm gear 41 and worm wheel 33, the two rotating parts 32 rotate simultaneously. Then, through the internal thread transmission, the two sliding parts... The simultaneous movement of plate 23 adjusts the distance between the second grinding roller 24 and the first grinding roller 2, thereby grinding dry suspensions of different particle sizes, increasing the applicability of the device, and driving the adjustment of the first baffle 44 and the second baffle 45. The size of the feed inlet 11 is adjusted by the first baffle 44 and the second baffle 45, that is, adjusted according to the position of the second grinding roller 24, to prevent the material from being thrown in front of the second grinding roller 24 during feeding. When it is necessary to grind the dry suspension, the distance between the two grinding rollers is adjusted to the minimum to ensure the grinding effect.
