Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical production, and in particular to a pharmaceutical production pulverizing device with an intelligent screening function. Background Art

[0002] In the pharmaceutical production field, drug crushing and screening are key pre-treatment steps in the preparation of dosage forms. The treatment effect of this step not only directly affects the stability of subsequent mixing, granulation, tableting and other processes, but also affects the dissolution rate, bioavailability and clinical efficacy of the final drug. Drug crushing is a prerequisite for achieving dosage form conversion. Solid preparations such as tablets and capsules need to be crushed to control the particle size of the raw materials within a specific range to meet the plasticity requirements of granulation. The physical forms of different drug raw materials need to be standardized through crushing. Mineral medicinal materials such as gypsum and magnet are originally hard blocks and need to be crushed into fine powder to increase the extraction rate of the active ingredients. Animal medicinal materials such as deer antler and antelope horn can eliminate the fiber structure after crushing to avoid the appearance of foreign body in the preparation.

[0003] However, most of the screens used in drug screening are currently fixed, which means that when screening smaller particles, the screen needs to be replaced, and it is generally troublesome to remove the screen. In addition, after the screen is replaced, it needs to be replaced with a new one at regular intervals. This means that when the screen is damaged, the screening machine needs to be stopped and disassembled for repair, which affects the continuity of screening. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems existing in the prior art and to propose a pharmaceutical production pulverizing equipment with intelligent screening function.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A pharmaceutical production pulverizing device with an intelligent screening function comprises a box body, a slot is opened on the side of the box body, the slot is used for the sliding of the screening box, a threaded rod is rotatably connected to the inside of the screening box, the threaded rod is threadedly connected to a strong adsorption magnet, and the strong adsorption magnet is used to support the screening mechanism, the screening mechanism comprises a screening shell arranged on the side of the strong adsorption magnet, the screening shell, a large-aperture screen is arranged inside the screening shell, a sweeping strip is arranged on the surface of the large-aperture screen, the side of the sweeping strip is fixedly connected to the cross bar, the side of the cross bar away from the sweeping strip is fixedly connected to a connecting frame, the connecting frame is fixedly connected to the side of the elliptical ring, and the inner wall of the screening shell is rotatably connected A disc is connected, and the disc is eccentrically provided with a cylindrical block. Another group of strong adsorption magnets is provided on the surface of the threaded rod. The strong adsorption magnets are used for another group of screening mechanisms that support small-aperture screens for screening. The screening shell is slidably connected to an electric door, and the side of the screening shell is fixedly connected to a slope groove. The above two groups of screening mechanisms have exactly the same structure but use different types of screens. The two groups of screening mechanisms have the same structure and the same effect. The equipment drives screens of different apertures to slide to the screening position by controlling the rotation of the threaded rod. Dynamic switching of screens can be achieved without stopping the machine for disassembly. Compared with the traditional fixed screen that needs to be stopped for replacement, this design greatly shortens the screen switching time and avoids production interruptions caused by screen replacement.

[0007] The above technical solution further includes:

[0008] An output motor is fixedly connected to the top of the box body, and the output end of the output motor is transmission-connected to a first belt, and the end of the first belt away from the output motor is transmission-connected to a second crushing roller, and the second crushing roller passes through the crushing box and is transmission-connected to a second belt, and the end of the second belt away from the second crushing roller is transmission-connected to the first crushing roller.

[0009] A support box is fixedly connected to the side of the box body, and the support box is used to support the screening box. The screening box can be slid out of the equipment slot through the handle to achieve modular overall disassembly. When the screen is damaged or blocked, the operator does not need to disassemble the equipment body, but only needs to pull out the screening box to complete the replacement of the faulty screen and the cleaning of the screening box. This design transforms the long-term shutdown maintenance of traditional equipment into rapid modular replacement.

[0010] The screening shell is fixedly connected with a connecting block, and the connecting block is slidably connected to the connecting frame.

[0011] A funnel is fixedly connected to the interior of the box, and an opening of the funnel is communicated with an opening at the bottom of the crushing box.

[0012] The box body is provided with a collection bucket for collecting pharmaceutical materials inside, and the bottom of the box body is provided with rollers for movement. The collection bucket is convenient for centrally storing qualified materials after screening, and the roller design facilitates equipment movement and work station adjustment.

[0013] The bottom of the screening box is provided with a discharge port for the screened material to fall into the collecting bucket, so that the screened fine particle material falls directly into the collecting bucket, realizing the process connection between screening and collection.

[0014] The slope trough is used to collect large particles of medicine, and the slope structure is used to automatically gather large particles that do not pass through the screen, which is convenient for subsequent unified processing.

[0015] The screening shell is provided with an interpenetrating hole inside, and the interpenetrating hole is used for the sliding of the sweeping bar, providing a guide track for the sliding of the sweeping bar, and ensuring that the sweeping bar stably moves the material during the screening process.

[0016] Another set of connecting frames for connecting sweep bars is provided on the side of the elliptical ring away from the connecting block. The symmetrical structure enhances the movement stability of the sweep bar assembly and ensures the uniformity of bidirectional material movement.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, the equipment drives screens of different apertures to slide to the screening position by controlling the rotation of the threaded rod, and the screens can be dynamically switched without stopping the machine for disassembly. Compared with the traditional fixed screen that needs to be stopped for replacement, this design greatly shortens the screen switching time and avoids production interruptions caused by screen replacement. When the size of the screening particles needs to be adjusted, it is only necessary to start the mechanical transmission structure to slide the corresponding screen into place, and then production can be put into operation immediately, which significantly improves the flexibility of multi-specification production, is suitable for small-batch and multi-variety pharmaceutical scenarios, and effectively reduces production pauses.

[0019] 2. In the present invention, the screening box can be slid out of the equipment groove by the handle to achieve modular overall disassembly. When the screen is damaged or blocked, the operator does not need to disassemble the equipment body, but only needs to pull out the screening box to complete the replacement of the faulty screen and the cleaning of the screening box. This design transforms the long-term shutdown maintenance of traditional equipment into a fast modular replacement, greatly shortening the maintenance cycle and ensuring the continuity of the screening process. It is especially suitable for continuous production scenarios and reduces the production capacity loss caused by equipment maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
