Description
Technical Field
[0001] This application relates to the technical field of powdered drug generating equipment, and more particularly to a powdered drug generating equipment. Background Technology
[0002] Powdered pharmaceuticals are widely used in the pharmaceutical and chemical industries, and their preparation requires key processes such as crushing and sieving. Traditional equipment typically uses mechanical crushing or air jet milling, combined with vibrating screens to achieve particle size classification. With increasing industry demands for fineness and uniformity of powders, efficient and integrated powdered pharmaceutical production equipment has become a research hotspot.
[0003] Currently, most equipment uses independent crushers and screening machines. Materials need to be crushed first and then transferred to the screening process. This not only increases the equipment footprint and energy consumption, but may also lead to dust pollution and material loss. In addition, the step-by-step operation can easily reduce production efficiency, and the crushed powder may affect the screening effect due to moisture absorption or agglomeration during the transfer process. Summary of the Invention

The output end of the crushing motor is fixedly connected to one end of the right-side crushing roller. A gear is fixedly connected to one end of each of the two crushing rollers. A drive sprocket is fixedly connected to the outer wall of the right-side gear. A rotating shaft is provided on the outer wall of the working chamber, and a driven sprocket is fixedly connected to one end of the rotating shaft located outside the working chamber. The drive sprocket and the driven sprocket communicate with each other. The shaft is connected by a chain, and a turntable is fixedly connected to one end inside the working chamber. A connecting rod is fixedly connected to the outer wall of the turntable. A screening box is set inside the working chamber. A linkage block is set on the side of the screening box facing the turntable. The connecting rod extends into the interior of the linkage block. Sliding rods are fixedly connected to both sides of the screening box. There are multiple sliding rods. One end of each sliding rod passes through the outer wall of the working chamber and is fixedly connected to a baffle. A spring is fixedly connected to the side of the baffle facing the outer wall of the working chamber. A screening box is set inside the screening box.
[0006] As a preferred embodiment, the outer walls of the two gears mesh with each other, a limit ring is provided on the outer wall of the rotating shaft, the right outer wall of the working chamber is located between the turntable and the limit ring, and the spring is located outside the slide rod.
[0007] As another preferred embodiment, the outer walls of both sides of the screening box are provided with limiting strips, and the inner walls of the screening box are provided with limiting grooves on both sides, with the limiting strips located inside the limiting grooves.
[0008] In a further preferred embodiment, the screening box is movably connected to a limiting door via a hinge, and the limiting door has a groove on its side, which is magnetically connected to the outer wall of the screening box.
[0009] Further preferably, the top of the inner wall of the working chamber is provided with a wedge-shaped block, and there are two wedge-shaped blocks. The two wedge-shaped blocks are respectively located on the top of the two crushing rollers. The working chamber is provided with a guide plate, which is funnel-shaped and located between the two crushing rollers and the screening box.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] (1) By setting up a crushing motor, crushing roller, gears, drive sprocket, rotating shaft, driven sprocket, turntable, connecting rod, screening box, linkage block, slide bar, baffle, spring, and screening box, in the initial state, the crushing motor and conveying motor are in standby mode, and the screening box is kept in a balanced position under the action of the spring.

[0027] Initially, the crushing motor 2 and the conveying motor 25 are in standby mode, and the screening box 10 is kept in a balanced position by the spring 14. During operation, the raw material is fed into the working chamber 1 through the top of the working chamber 1, the crushing motor 2 is started to drive the right crushing roller 3 to rotate, and the left crushing roller 3 is rotated in the opposite direction by the meshing gear 4, and the two rollers work together to complete the material crushing. The crushed material falls into the screening box 15 through the guide plate 21. At the same time, the drive sprocket 5 drives the driven sprocket 7 to rotate through the chain, which causes the rotating shaft 6 to drive the turntable 8 to rotate. The linkage rod 9 pushes the linkage block 11 to drive the screening box 10 to vibrate back and forth along the slide rod 12. The spring 14 provides the restoring force to enhance the screening effect. Under the action of vibration, the powdered agent that meets the particle size requirements falls into the lower screening box 15 through the mesh of the upper screening box 15.

At the same time, the drive sprocket 5 drives the driven sprocket 7 to rotate through the chain, so that the rotating shaft 6 drives the turntable 8 to rotate. The linkage rod 9 pushes the linkage block 11 to drive the screening box 10 to vibrate back and forth along the slide rod 12. The spring 14 provides the restoring force to enhance the screening effect. Under the action of vibration, the powdered agent that meets the particle size requirements falls into the lower screening box 15 through the mesh of the upper screening box 15. The powdered agent only needs to remain in the screening box 15 for secondary screening. The integrated design realizes the linkage operation of crushing and screening. It has the advantages of compact structure, sealed dust prevention, low energy consumption and high efficiency. It solves the problems of dust pollution and material loss in traditional separate equipment. After screening, the magnetic limit door 18 can be opened to take out the screening box 15 and clean the inside of the screening box 15.
