Description

Technical Field

[0001] This utility model relates to the field of tableting device technology, specifically a dustproof tableting device for pharmaceutical use. Background Technology

[0002] In the production and processing of traditional Chinese medicine (TCM), herbs are sometimes made into tablets. Each tablet contains a relatively fixed amount of medicine, ensuring accurate dosage for each patient and facilitating control of treatment effects. Compared to traditional decoctions, TCM tablets are small, lightweight, and easy to carry and take, making them particularly suitable for people living fast-paced modern lives. Patients can simply swallow the tablets with water, eliminating the time and effort required for decocting. The production process of TCM tablets begins with pretreatment of the herbs. After careful selection and washing, the herbs are pulverized to increase the contact area with the solvent. Next, appropriate methods such as decoction and soaking are used to extract the active ingredients. The residue is then removed by filtration, and the extract is concentrated using methods such as vacuum distillation. Subsequently, excipients such as starch and dextrin are added to the concentrate to create a soft mass. Granulation methods such as extrusion and fluidized bed granulation are then used to obtain granules or powder. Finally, the granules are compressed into tablets using a tablet press.

[0003] A search revealed that Chinese Patent Publication No. CN221187629U discloses a rotary tablet press, belonging to the field of tablet presses. The press includes a base with a tableting turntable and a feeding device mounted on its upper end. The turntable consists of a rotating shaft, a base plate, a middle mold, a top plate, a push rod, a forming hole, and a pressure rod. A cleaning device is also installed on the upper end of the base. This device comprises an L-shaped support rod, a mounting rod, an anti-detachment plate, a spring, a baffle, a base rod, a rubber scraper, and a collection box. By using this cleaning device, the rubber scraper adheres tightly to the upper end of the middle mold under the elastic force of the spring. As the middle mold rotates, friction occurs between the scraper and the upper end, causing the scraper to remove the material adhering to the upper end of the mold. The scraped material falls into the collection box, thus collecting the material adhering to the upper end of the middle mold and reducing material waste.

[0004] However, this device also has the following drawbacks:

[0005] Existing technologies may result in drug powder adhering to the surface of the tableting device or scattering into the air during processing, causing contamination of the processing and potentially affecting the health of operators. This device does not solve this problem. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A dustproof tableting device for pharmaceutical use includes a processing table 1, a rotary tableting machine body 2 mounted on the top of the processing table 1, a feeding hopper 18 fixedly mounted on one side of the top surface of a transparent protective cover 3, a material pipe 19 fixedly mounted on the bottom of the feeding hopper 18, a material frame 20 disposed below the material pipe 19, and the material frame 20 fixedly connected to the top surface of the processing table 1 through a support frame 21.

[0028] By setting up a rotary tablet press body 2, the turntable of the rotary tablet press body 2 can be driven by the built-in motor to rotate. Multiple punches are evenly distributed on the turntable. When the turntable rotates, the punches will pass through different working areas in sequence. Granular material is added into the die hole of the turntable through the feeding hopper 18, the material pipe 19 and the material frame 20. As the turntable rotates, the material in the die hole is first pre-compacted by the pre-compression roller. The pre-compacted material continues to rotate with the turntable to the position of the main pressure roller. The main pressure roller applies greater pressure to the material, compressing the material into the required tablets. Finally, the compressed tablets are pushed out of the die hole by the tablet ejection device, completing the entire tableting process.

[0029] It also includes protective components, including a transparent protective cover 3, which is located on the outside of the rotary tablet press body 2. A movable seat 4 is fixedly installed on one side of the transparent protective cover 3. The movable seat 4 is installed on the surface of the lead screw 5. The top of the lead screw 5 is rotatably installed on the top plate 10, and the bottom of the lead screw 5 is rotatably installed on the bottom plate 11. The bottom plate 11 is fixedly connected to the side wall of the processing table 1. The bottom of the lead screw 5 is connected to the output end of the drive motor 12. The drive motor 12 is fixedly installed on the bottom of the bottom plate 11. Two sets of guide rods 13 are provided on both sides of the lead screw 5. The top and bottom of the guide rods 13 are fixedly connected to the top plate 10 and the bottom plate 11, respectively. A slide seat 14 is slidably installed on the surface of the guide rods 13. The slide seat 14 is fixedly connected to the transparent protective cover 3. The nozzles 7 are fixedly installed on the side of the transparent protective cover 3 adjacent to the movable seat 4. The nozzles 7 are connected to each other through a vent pipe 15. An air inlet 16 is fixedly installed on one side of the vent pipe 15.

[0030] By setting up a transparent protective cover 3, the rotary tablet press body 2 can be isolated from the outside air, preventing drug powder from polluting the processing environment and also preventing harm to the health of operators. By setting up a drive motor 12 and a lead screw 5, the transparent protective cover 3 can be opened upwards, making it convenient for operators to maintain the rotary tablet press body 2. By setting up a nozzle 7, a high-speed airflow can be sprayed after connecting to an external air source, which can blow up the drug powder attached to the rotary tablet press body 2 and the top of the processing table 1, thus facilitating the collection of drug powder.

[0031] It also includes a dust removal component, which includes a fan 6 and multiple nozzles 7. The fan 6 is installed on one side of the bottom of the processing table 1. The air inlet of the fan 6 is connected to the bottom of the dust collection channel 8. The top opening of the dust collection channel 8 is located below the dust collection hole 9. The dust collection hole 9 is opened around the top of the processing table 1. A dust collection bag 17 is installed inside the dust collection channel 8. The dust collection channel 8 is located inside the processing table 1 and is fixedly connected to the processing table 1.

[0032] By setting up the fan 6, the drug dust inside the transparent protective cover 3 can be collected through the dust suction channel 8 and dust suction hole 9, preventing the drug dust from accumulating in the transparent protective cover 3, preventing contamination of the rotary tablet press body 2, and facilitating the operator to collect and reuse residual drug powder.

[0033] In practical use, the cost reduction device is moved to the designated position. When the rotary tablet press body 2 is working, the bottom of the transparent protective cover 3 is kept in contact with the top surface of the processing table 1. The blower 6 is turned on and the blower 6 quickly draws out the air inside the dust suction channel 8, forming a negative pressure inside the dust suction channel 8. The negative pressure draws the air inside the transparent protective cover 3 and the drug powder into the dust suction channel 8 through the dust suction hole 9. The air is discharged through the pores of the dust collection bag 17, and the drug powder is collected in the dust collection bag 17. After processing, the air inlet 16 can be connected to an external air source, and a high-speed airflow can be input into the nozzle 7 through the air pipe 15. The nozzle 7 sprays out the high-speed airflow, blowing up the drug powder attached to the surface of the rotary tablet press body 2. At the same time, the rotary table of the rotary tablet press body 2 is controlled to rotate, so that dust can be removed from different positions of the rotary tablet press body 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
