The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides a rotary tablet press, such as Figure 1-4 As shown, the rotary tablet press comprises: a rotary tablet press body 2 mounted on the top of a base 1 for extruding captopril tablets; a material guide plate 3 fixed on the rotary tablet press body 2, the side section of the material guide plate 3 being U-shaped; a collection box 4 arranged on one side of the rotary tablet press body 2 for collecting captopril tablets; a collection box 5 arranged inside the collection box 4 for isolating complete captopril tablets, the collection box 5 being provided with a plurality of through holes; a screening component mounted on the top of the base 1 and located on one side of the rotary tablet press body 2, the screening component being used to screen out tablet debris mixed in the captopril tablets.
[0022] In this embodiment, the collecting box 4 is used to collect the extruded tablets, and the collecting box 5 achieves isolation of the complete tablets through the multiple through holes thereon, preventing the mixing of tablet debris and complete tablets, improving the purity of the tablets, and further ensuring the quality of the medicines.
[0023] In a further preferred embodiment of the utility model, the screening assembly includes a plurality of fixed plates 6 installed in the aggregate box 4; a spring 7 fixed on the plurality of fixed plates 6; a support ring 8 installed on the top of the plurality of springs 7, the support ring 8 being in contact with the inner wall of the aggregate box 4; a screen 9 arranged in the support ring 8, the screen 9 being in contact with the bottom of the collection box 5; a powder box 13 movably placed in the aggregate box 4 for collecting powder, the powder box 13 being located below the fixed plates 6; and two drive assemblies arranged in the aggregate box 4 for assisting in screening.
[0024] In this embodiment, the fixed plate 6 provides stable support for other parts of the screening assembly, and an elastic supporting structure is formed by the spring 7, so that the screen 9 can have a certain buffer when it is impacted by the tablets, thereby ensuring the smooth screening. The main function of the screen 9 is to screen the tablets discharged from the rotary tablet press body 2, and to screen out impurities such as tablet crumbs to ensure the purity of the tablets in the collection box 5. The powder box 13 is used to collect the powder and other impurities sieved from the screen 9, thereby realizing the effective classification and collection of medicines.
[0025] In a further preferred embodiment of the utility model, the driving assembly includes an adjustment plate 10 installed at the bottom of the support ring 8; a motor 11 fixed in the aggregate box 4; and a cam 12 installed on the output shaft of the motor 11, and the cam 12 is in contact with the adjustment plate 10.
[0026] In this embodiment, the motor 11 serves as a source of driving force. When the motor 11 is running, the output shaft drives the cam 12 to rotate. The contact between the cam 12 and the adjusting plate 10 causes the adjusting plate 10 to reciprocate. This reciprocating motion is transmitted to the screen 9 through the support ring 8, causing the screen 9 to vibrate or swing, thereby realizing the screening and impurity removal of tablets. Through the design of the drive component, the screening component can more efficiently screen out tablet debris and other impurities, thereby improving the quality and purity of the medicine. The coordinated use of the motor 11 and the cam 12 makes the vibration or swing of the screen 9 more stable and reliable, thereby extending the service life of the equipment.
[0027] In a further preferred embodiment of the utility model, a fan 16 and a dust box 17 are fixed to the bottom of the collecting box 4, the air inlet end of the fan 16 is connected to the dust box 17, a connecting pipe 18 is installed on the dust box 17, a dust suction pipe ring 19 is fixed to the air inlet end of the connecting pipe 18, and the dust suction pipe ring 19 is arranged on the rotary tablet press body 2.
[0028] In this embodiment, when the fan 16 is working, air is sucked in through the dust box 17, and impurities such as dust are sucked in and stored in the dust box 17. The dust suction pipe ring 19 is located close to the area where the medicine is squeezed and discharged. In this way, when the rotary tablet press body 2 is working, the generated dust and impurities such as tablet debris can be effectively sucked in by the dust suction pipe ring 19 and enter the dust box 17 through the connecting pipe 18, thereby realizing the effective collection and cleaning of dust and debris generated in the drug production process. This not only keeps the production environment clean, reduces the mixing of impurities, and improves the quality of the medicine, but also protects the health of operators and reduces safety risks in the production process.
[0029] In a further preferred embodiment of the utility model, a plurality of dust suction ports are provided on the dust suction pipe ring 19, and the plurality of dust suction ports are all located below the extrusion port on the rotary tablet press body 2. A top cover mounting frame 20 is provided on the top of the base 1, and a top cover for protecting the processing environment of Captopril tablets is installed on the top cover mounting frame 20.
[0030] In this embodiment, when the rotary tablet press is working, the generated dust, tablet crumbs and other impurities can be effectively sucked in through these dust suction ports, thereby achieving efficient collection of dust and crumbs. At the same time, the position design of the dust suction port can effectively prevent the powder for extrusion into tablets from being directly sucked out. The top cover can effectively isolate dust and impurities in the external environment and prevent them from entering the drug production process, further ensuring the purity and quality of the drugs, and improving the cleanliness of the production environment and the purity of the drugs.
[0031] In a further preferred embodiment of the utility model, rubber pads are fixedly sleeved outside the two cams 12, and the two rubber pads are respectively in contact with the two adjustment plates 10. A limiting telescopic rod 15 is provided inside the plurality of springs 7, and the plurality of limiting telescopic rods 15 are connected to the support ring 8.
[0032] In this embodiment, the rubber pad, as a soft material with a certain elasticity, can effectively reduce the friction and impact between the cam 12 and the adjusting plate 10, thereby extending the service life of the equipment and improving the stability of operation. At the same time, the provision of the rubber pad also makes the contact between the cam 12 and the adjusting plate 10 closer, ensuring the effective transmission of the driving force. The limiting telescopic rod 15 is connected to the support ring 8, which plays a supporting and limiting role for the spring 7. When the spring 7 is subjected to external force, the limiting telescopic rod 15 can ensure that the spring 7 maintains a stable shape during the extension and retraction process, preventing the spring 7 from twisting or deformation.
[0033] In a further preferred embodiment of the present invention, an opening is provided on one side of the material collection box 4, and a handle 14 is installed on one side of the powder box 13 close to the opening, and the handle 14 extends to the outside of the material collection box 4 through the opening.
[0034] In this embodiment, the opening facilitates the removal and placement of the powder box 13. The operator can easily pull the powder box 13 out of or push it into the collection box 4 through the handle 14, which improves the convenience of operation and reduces the difficulty and time cost of equipment maintenance.
[0035] In a further preferred embodiment of the present invention, the powder box 13 is provided with an observation window, and the bottom of the powder box 13 is inlaid with a plurality of balls, and the plurality of balls are in contact with the bottom inner wall of the collecting box 4.
[0036] In this embodiment, the design of the observation window enables the operator to intuitively understand the powder collection situation in the powder box 13, so as to promptly judge whether the powder box 13 needs to be cleaned or replaced. When it is necessary to take out or put in the powder box 13, the operator only needs to apply a little force, and the powder box 13 can smoothly slide out or slide into the collection box 4 through the rolling action of the ball, thereby improving the convenience and efficiency of operation and reducing labor intensity.
[0037] In summary, compared with the relevant technology, the present device can collect the discharged medicines in time by setting the collecting box 4, can screen the tablets by setting the screening component, and can screen out the debris in the tablets to ensure the purity of the tablets, and can absorb the medicine dust on the conveyor belt by setting the fan 16, the dust collecting box 17 and the dust suction pipe ring 19, thereby reducing environmental pollution and protecting the health of the staff.
