Description

Technical Field

[0001] This utility model relates to the field of granulation machine technology, specifically a high-speed mixing granulation machine for drug production. Background Technology

[0002] The pellet mill mainly consists of a feeding, mixing, pelleting, transmission, and lubrication system. Its working process requires that the compound powder with a moisture content of no more than 15% enter the feeding auger from the hopper. By adjusting the speed of the continuously variable speed motor, a suitable material flow rate is obtained. Then, it enters the mixer, where it is stirred and mixed with steam for conditioning by the stirring rod. If molasses or oil needs to be added, it is also added from the mixing drum and conditioned together with the steam. The amount of oil added is generally no more than 3%, otherwise it will be difficult to form. After conditioning, the temperature of the compound powder can reach 64-85℃ and the humidity can reach 14-16%. Then, it passes through an inclined chute and an optional iron suction device to remove iron impurities mixed in the powder. Finally, it enters the pressing chamber for pelleting.

[0003] In current high-speed mixing granulators for drug production, materials tend to adhere to the inner wall of the granulator during the granulation process. As production continues, the material accumulates, affecting not only the uniformity of mixing and granulation effect but also hindering the granulation process, resulting in low granulation efficiency and making it difficult to meet the needs of large-scale drug production. To solve the material adhesion problem, some granulators use mechanical impact to remove material from the inner wall. However, due to the lack of an effective buffer structure, the impacting components generate a large rigid impact when hammering the inner wall of the granulator. This not only damages the granulator itself and shortens its service life but also accelerates the wear of the impacting components, increasing maintenance costs and replacement frequency. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed mixing and granulation machine for drug production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed mixing and granulation machine for drug production, comprising a granulator and a discharge port, wherein a discharge port is fixed to one side wall of the granulator, a driving component is fixed to one side wall of the granulator, a linkage component is wound around one inner side wall of the driving component, a driven component is fixed to the bottom end of the linkage component, and a plurality of support hammer springs are fixed to the outer wall of the bottom end of the driven component, and a circular hammer head is fixed to one end of each support hammer spring.

[0006] Preferably, the outer wall of the circular hammer is provided with a rubber pad, which can buffer the hammering force when it strikes the outer wall of the granulator.

[0007] Preferably, the driving component includes a drive motor, the drive motor is fixed to one side wall of the granulator, a linkage rod is fixed to the top of the output shaft of the drive motor, and a drive pulley is fixed to the top of the linkage rod.

[0008] Preferably, the linkage component includes a linkage belt, the outer wall of the drive pulley is wound with the linkage belt, the other side of the linkage belt is wound with a driven pulley, and the inner wall of the driven pulley rotates on the outer wall of the granulator.

[0009] Preferably, the driven component includes a limiting toothed ring, the limiting toothed ring is fixed to the top of the outer wall of the granulator, a support rotating block is fixed to the bottom of the driven pulley, a support hammer rotating rod is rotatably mounted at the bottom of the support rotating block, a drive gear is fixed to the outer wall of the support hammer rotating rod, and the drive gear meshes with the limiting toothed ring.

[0010] Preferably, the outer wall of the limiting toothed ring is provided with teeth that match the drive gear, and the meshing of the teeth can drive the support hammer rod to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The drive motor transmits power stably to the driven component through a transmission system consisting of a linkage rod, drive pulley, linkage belt, and driven pulley. The drive gear in the driven component meshes with the limiting gear ring, causing the support hammer rod to rotate periodically. This allows the circular hammer head to continuously strike the outer wall of the pellet mill, effectively removing material adhering to the inner wall of the pellet mill and preventing material accumulation from affecting the pelleting process. This ensures the continuity of the pelleting process and significantly improves pelleting efficiency.

[0013] The support spring is compressed and stores energy at the moment of impact of the circular hammer head, and the rubber pad further absorbs the impact force. The double buffer structure significantly reduces the rigid impact of the hammer head on the pellet mill, which not only avoids damage to the equipment due to long-term excessive impact force, but also reduces the wear between the hammer head and the outer wall of the pellet mill, effectively extending the service life of the pellet mill and related components and reducing equipment maintenance costs.

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a high-speed mixing granulator for drug production, including a granulator 1 and a discharge port 2. The discharge port 2 is fixed to one side wall of the granulator 1. A driving component is fixed to one side wall of the granulator 1. A linkage component is wound around the inner wall of one side of the driving component. A driven component is fixed to the bottom end of the linkage component. A plurality of hammer springs 12 are fixed to the outer wall of the bottom end of the driven component. The hammer springs 12 play a role in buffering and storing energy for the circular hammers 13. At the moment of impact, the springs are compressed and absorb part of the impact force to avoid excessive impact force from damaging the granulator 1. A circular hammer 13 is fixed to one end of the hammer spring 12. During the rotation of the hammer rod 10, the circular hammer 13 is driven to rotate through the hammer rod 10, so that it periodically hits the outer wall of the granulator 1. A rubber pad is provided on the outer wall of the circular hammer 13 to buffer the hammering force of the hammer hitting the outer wall of the granulator 1.

[0023] The driving component includes a drive motor 3. The drive motor 3 is fixed to one side wall of the pellet mill 1. When the drive motor 3 is started, it drives the linkage rod 4 at the top of the output shaft to rotate. The linkage rod 4 is fixed to the top of the output shaft of the drive motor 3. The linkage rod 4 transmits the rotational motion of the motor to the drive pulley 5, which rotates accordingly. The drive pulley 5 is fixed to the top of the linkage rod 4. The linkage belt 6 is sleeved on the drive pulley 5 and the driven pulley 7. The transmission relationship is formed by the friction between the belt and the pulley.

[0024] The linkage includes a linkage belt 6. The outer wall of the drive pulley 5 is wound with the linkage belt 6. When the drive pulley 5 rotates, the tension of the linkage belt 6 drives the driven pulley 7 to rotate synchronously on the outer wall of the pellet mill 1. The driven pulley 7 is wound inside the other side of the linkage belt 6, and the inner wall of the driven pulley 7 rotates on the outer wall of the pellet mill 1. The support rotating block 9 fixed at the bottom of the driven pulley 7 rotates together with the driven pulley 7.

[0025] The driven component includes a limiting gear ring 8. The limiting gear ring 8 is fixed at the top of the outer wall of the granulator 1. During rotation, the drive gear 11, due to the meshing of the teeth with the limiting gear ring 8, will roll along the circumference of the limiting gear ring 8 according to the gear transmission principle. The bottom end of the driven pulley 7 is fixed with a support rotating block 9. The support rotating block 9 drives the support hammer rotating rod 10 connected to it to move. The bottom end of the support rotating block 9 rotates the support hammer rotating rod 10. The rotation of the support hammer rotating rod 10 causes the multiple support hammer springs 12 and the circular hammer head 13 fixed on the bottom outer wall to move accordingly. The outer wall of the support hammer rotating rod 10 is fixed with a drive gear 11, and the drive gear 11 meshes with the limiting gear ring 8. The drive gear 11 will roll along the circumference of the limiting gear ring 8, thereby driving the support hammer rotating rod 10 to rotate around the axis. The outer wall of the limiting gear ring 8 is provided with teeth that match the drive gear 11. Through mutual meshing, the support hammer rotating rod 10 can be driven to rotate.

[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0027] After the drive motor 3 starts, the linkage rod 4 at the top of its output shaft also rotates. The linkage rod 4 transmits the rotational motion of the drive motor 3 to the drive pulley 5. The linkage belt 6 is wound around the outer wall of the drive pulley 5 and the driven pulley 7. The friction between the linkage belt 6 and the drive pulley 5 and the driven pulley 7 drives the driven pulley 7 to rotate. The support rotating block 9 fixed at the bottom of the driven pulley 7 also rotates. The support rotating block 9 drives the support hammer rotating rod 10 to rotate. The support hammer rotating rod 10 drives the drive gear 11 to rotate. The drive gear 11 and the limit The positioning gear rings 8 mesh with each other, and the limiting gear rings 8 remain stationary. During the rotation of the drive gear 11, according to the gear transmission principle, the drive gear 11 will roll along the circumference of the limiting gear ring 8, thereby driving the support hammer rotating rod 10 to rotate. The support hammer rotating rod 10 drives the support hammer spring 12 to rotate. When the support hammer spring 12 rotates, the circular hammer head 13 fixed at one end of it also rotates. The circular hammer head 13 rotates and hammers the outer wall of the granulator 1, thereby removing the material adhering to the inner wall of the granulator 1, ensuring the smooth progress of the granulation process, and improving the quality and efficiency of granulation.
