Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical granulators, specifically an extrusion-type pharmaceutical granulator. Background Technology

[0002] The pharmaceutical industry is closely related to people's health and quality of life. The continuous discovery of new drugs and the great progress in treatment methods have brought about tremendous changes in the pharmaceutical industry. As a result, drugs are constantly being innovated. In the process of manufacturing drugs, the drug ratio needs to be determined in advance. During production, the drug powder is put into a tablet granulator for extrusion to obtain the finished product, which is then put into the market for sale. This is the most critical step in manufacturing drugs.

[0003] According to Chinese Patent No. CN220923386U, an extrusion-type pharmaceutical granulator is disclosed. This extrusion-type pharmaceutical granulator, through the setting of a powder descent slowing device, tablet extrusion forming rollers, etc., when the powder is poured from the feeding funnel into the protective shell and pressed into tablets by the tablet extrusion forming rollers, when the powder descends, it first contacts the buffer plate. The buffer plate rotates downward and its lower end contacts the rubber top block, thereby buffering the impact of the powder and slowing down its descent speed. This makes it easier for the tablet extrusion forming rollers to control the size of the tablets after pressing when the powder descends at a uniform speed.

[0004] Regarding the aforementioned patent content, the device has a collection box installed below the granulation chamber to collect granular materials. However, the collection box is fixed in place, causing granules to accumulate locally inside the collection box. This reduces the actual effective capacity of the collection box, requiring frequent manual stops to adjust the position of the collection box or to smooth the material inside by hand. Frequent manual smoothing of the material inside the collection box increases the workload of the staff, and frequent stops affect the continuity of granulation. Furthermore, frequent stops interrupt the granulation process, directly reducing the overall granulation output and affecting the efficiency of material collection. Utility Model Content

The speed of the first motor 4 and the second motor 15 is set through the control panel 18. The collection box 32 is aligned with the positioning groove 29 of the pad 34 through the positioning block 30 to ensure that the collection box 32 is located directly below the discharge port 37. Then, the medicine powder is put into the feed hopper 3. The first motor 4 drives the conveying shaft 5 to rotate. The spiral blades 6 on the outer wall of the conveying shaft push the powder forward along the conveying chamber 2. The powder falls accurately into the two extrusion forming rollers 11 in the granulation chamber 8 through the discharge pipe 7. The second motor 15 drives the movable shaft 10 to rotate. The driving gear 16 on the movable shaft 10 meshes with the driven gear 17 on the drive shaft 9. The movable shaft 10 drives the drive shaft 9 to rotate. At the same time, the movable shaft 10 and the drive shaft 9 rotate synchronously in opposite directions. The two extrusion forming rollers 11 rotate with the shaft and extrude the powder into regular granules through mechanical pressure. The granules fall through the discharge port 37 at the bottom of the granulation chamber. The movable shaft 10 extends to one end of the back of the machine body and drives the rotating shaft 20 to rotate through the sprocket 36 and chain 35; the driving bevel gear 21 on the rotating shaft 20 meshes with the driven bevel gear 22 on the connecting shaft 23, converting the horizontal transmission into vertical transmission, driving the turntable 24 at the bottom of the connecting shaft to rotate, and the turntable 24 pulls the pad 34 through the pull plate 25. The roller 28 at the bottom of the pad 34 moves back and forth along the guide rail 26, so that the collection box 32 can evenly receive the falling particles and avoid local accumulation. After granulation is completed, turn off the motor via the control panel 18; hold the handles 33 on both sides of the collection box 32 and lift the collection box 32 upwards.
