Description

Technical Field

[0001] This utility model relates to the field of dust collection device technology, specifically a tablet press with a dust collection mechanism. Background Technology

[0002] Tablet presses are primarily used in pharmaceutical industry tablet manufacturing processes. They are automated, continuous production equipment that compresses granular materials into round, irregularly shaped, or tablet-like products with text, symbols, or graphics, with a diameter not exceeding 13mm. Rotary tablet presses consist of multiple sets of punches evenly distributed on a turntable that move in a circular motion along a specific trajectory, compressing granular materials into tablets via pressure rollers. During operation, some fine powder adheres to the tablet press's die plate and molds. Prolonged friction can generate black solid contaminants or oil stains. These contaminants severely affect product quality, therefore, there is an urgent need to design a tablet press with a dust extraction mechanism to effectively clean the powder from the die plate surface. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a tablet press with a dust collection mechanism.

[0004] To solve the above problems, the technical solution of this utility model is as follows: a tablet press with a dust collection mechanism, including a frame and a tablet pressing mechanism on the top surface of the frame. A discharge port is provided at one end of the tablet pressing mechanism. Two nut pillars are fixedly provided on the top surface of the frame near the discharge port. A connecting seat is provided on the top surface of the two nut pillars. Locking bolts that are adapted to the nut pillars are respectively provided on the top surface of the connecting seat at the corresponding positions. A main dust collection chamber is provided on the end surface of the frame near the connecting seat. A dust collection pipe is provided on the end surface of the connecting seat near the tablet pressing mechanism. Multiple dust collection heads are provided at equal intervals along the axial direction of the dust collection pipe. A pipe is also provided on the end surface of the dust collection pipe that communicates with it. The end of the pipe away from the dust collection pipe is connected to the main dust collection chamber and communicates with it.

[0005] Furthermore, the main dust collection chamber is equipped with a filter curtain, and an exhaust fan and a secondary dust collection chamber are arranged sequentially from left to right on the top surface. The air inlet of the exhaust fan is connected to the secondary dust collection chamber, and the secondary dust collection chamber and the main dust collection chamber are connected by a connecting pipe. A filter screen is also provided at the connection between the connecting pipe and the main dust collection chamber. Water is stored inside the secondary dust collection chamber, and a drain outlet is provided on its outer end face.

[0006] Furthermore, the water level in the secondary dust collection chamber is lower than the height of the exhaust fan inlet.

[0007] Furthermore, a drain outlet is also provided on the outer side of the main vacuum chamber.

[0008] Furthermore, the connecting seat has an arc-shaped structure, and its end is located in the middle of the upper and lower mold turntables of the tablet pressing mechanism.

[0009] The advantages of this invention compared to existing technologies are as follows: Through the connecting seat between the upper and lower mold turntables on the tableting mechanism, and the suction pipe and multiple suction heads on the inner side of the connecting seat, the powder on the surface of the upper and lower mold turntables can be thoroughly and effectively cleaned during rotation, thus increasing the quality of dust collection. The coordinated action of the filter curtain, exhaust fan, and auxiliary suction chamber within the main suction chamber allows for the processing of larger powder or particles in the main suction chamber, followed by the transfer of smaller particles to the auxiliary suction chamber for further processing under the action of the filter curtain. This layered processing of powder or particles improves the dust collection efficiency. In use, this invention not only provides comprehensive and uniform cleaning of powder or particles but also enables layered dust collection, thereby enhancing the overall efficiency of the device.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3As shown, a tablet press with a dust collection mechanism includes a frame 1 and a tablet pressing mechanism 2 on the top surface of the frame 1. A discharge port 3 is provided at one end of the tablet pressing mechanism 2, which conveys and collects the pressed tablets. Two nut posts 4 are fixedly installed on the top surface of the frame 1 near the discharge port 3. A connecting seat 5 is provided on the top surface of the two nut posts 4. The connecting seat 5 has an arc-shaped structure, and its end is located in the middle of the upper and lower mold turntables of the tablet pressing mechanism 2. Locking bolts 6, corresponding to the nut posts 4, are respectively inserted into the top surface of the connecting seat 5. The locking bolts 6 and the nut posts 4 connect and fix the connecting seat 5. A main dust collection chamber 10 is also provided on the end face of the frame 1 near the connecting seat 5. The main dust collection chamber 10 is a prior art... After activation, the device can directly perform dust collection operations through the pipeline connection. A dust collection pipe 7 is provided on the end face of the connecting seat 5 near the tablet pressing mechanism 2. The dust collection pipe 7 has an arc-shaped structure that is adapted to the end face of the connecting seat 5. Multiple dust collection heads 8 are also provided at equal intervals along the axial direction of the dust collection pipe 7. When the mold turntable on the tablet pressing mechanism 2 rotates, the powder or particles on its surface are thoroughly and effectively cleaned under the action of the multiple dust collection heads 8. A pipeline 9 is also provided on the end face of the dust collection pipe 7, which is connected to it. The end of the pipeline 9 away from the dust collection pipe 7 is connected to the main dust collection chamber 10 and is interconnected with it. A drain outlet 17 is also provided on the outer side of the main dust collection chamber 10. Under the action of the drain outlet 17, the powder or particles absorbed in the main dust collection chamber 10 are effectively cleaned.

[0016] The main dust collection chamber 10 is equipped with a filter curtain 11, which effectively filters larger powders or particles in the main dust collection chamber 10. From left to right, the top surface is also equipped with an exhaust fan 13 and a secondary dust collection chamber 14. The air inlet of the exhaust fan 13 connects to the secondary dust collection chamber 14, and the secondary dust collection chamber 14 and the main dust collection chamber 10 are connected by a connecting pipe 15. A filter screen 12 is installed at the connection between the connecting pipe 15 and the main dust collection chamber 10. The secondary dust collection chamber 14 stores water, and a drain outlet 16 is provided on its outer end face. The water level in the secondary dust collection chamber 14 is lower than the height of the air inlet of the exhaust fan 13. Under the action of the exhaust fan 13 and the secondary dust collection chamber 14, smaller powders or particles are drawn into the secondary dust collection chamber 14 through the connecting pipe 15. The particles move within the connecting pipe 15 with the airflow from the exhaust fan 13, and after being sprayed onto the pipe wall, they fall into the water, thus preventing them from being discharged to the outside and causing secondary pollution.

[0017] In practical use, the device is placed in a designated position. During the pressing process of the tablet pressing mechanism 2, the mold turntables at both ends are rotated. At this time, the main dust collection chamber 10 and the exhaust fan 13 are activated. Under the action of the dust collection head 8, dust collection pipe 7 and pipe 9, the powder or particles are absorbed into the main dust collection chamber 10. Under the action of the filter curtain 11, larger powder or particles are retained in the main dust collection chamber 10, while smaller powder or particles are absorbed into the auxiliary dust collection chamber 14 through the connecting pipe 15 under the action of the exhaust fan 13. When the particles move in the connecting pipe 15 with the air force of the exhaust fan 13, they are sprayed onto the pipe wall and fall into the water, so they are not discharged to the outside and cause secondary pollution. In the process of use, this utility model can not only perform comprehensive and uniform cleaning of powder or particles, but also perform layered dust collection treatment, thereby improving the efficiency of the device.
