Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a tableting device for pharmaceutical production, comprising a housing 1, a pressing assembly 2 rotatably mounted inside the housing 1, a flipping motor 3 fixedly mounted on the outside of the housing 1 and connected to the pressing assembly 2, a pressing cylinder 4 fixedly mounted at the top inside the housing 1, a sliding plate 5 fixedly mounted at the bottom of the pressing cylinder 4, a pressing rod 6 fixedly connected to the bottom of the sliding plate 5, a suction hood 7 fixedly mounted at the bottom inside the housing 1, and a cleaning assembly 9 movably mounted on the inside of the housing 1 below the pressing assembly 2; the pressing assembly 2 includes an upper frame 21 and a lower frame 22, with pressing grooves 23 equidistantly opened inside the upper frame 21 and the lower frame 22. The inner side of 22 is movably connected to a sliding seat 24. The top and bottom of the sliding seat 24 are respectively fixedly connected to top blocks 25 corresponding to the pressing groove 23. In use, the medicine powder is placed in the upper pressing groove 23, and then the pressing electric cylinder 4 is operated to lower the slide plate 5. The pressing rod 6 at the bottom of the slide plate 5 is used to press the medicine powder to form a tablet. Then, the pressing electric cylinder 4 drives the slide plate 5 to reset, and the flipping motor 3 drives the pressing assembly 2 to flip, turning the upper pressing groove 23 to the bottom, allowing the tablet to fall into the suction hood 7. The weight of the sliding seat 24 causes the top block 25 to slide into the inside of the pressing groove 23, pushing out any tablets that may be stuck, ensuring that there is no residue in the pressing groove 23, thereby improving the convenience of operation.

[0024] Both the upper frame 21 and the lower frame 22 have connecting holes 26 on their left and right sides. Fixing bolts 27 are movably installed inside the connecting holes 26, and fixing nuts 28 are movably installed outside the fixing bolts 27. Through the cooperation of fixing bolts 27 and fixing nuts 28, the upper frame 21 and the lower frame 22 can be fixedly connected, which improves the structural stability of the pressing assembly 2, ensures the accuracy and positional stability of the pressing groove 23 during use, and avoids deformation or misalignment of the pressing groove 23, thereby ensuring the pressing quality of the tablets. At the same time, the setting of fixing bolts 27 and fixing nuts 28 also makes it easy for users to disassemble and maintain the pressing assembly 2, improving the practicality and convenience of the device.

[0025] A limiting electric cylinder 29 is fixedly installed on the inner side of the housing 1. The upper frame 21 and the lower frame 22 are provided with limiting holes corresponding to the limiting electric cylinder 29 on the side near the limiting electric cylinder 29. The output end of the limiting electric cylinder 29 can pass through the limiting hole and contact the upper frame 21 and the lower frame 22. By extending and retracting the limiting electric cylinder 29, the upper frame 21 and the lower frame 22 can be limited and fixed, which further improves the stability of the pressing assembly 2 during use and avoids displacement or shaking caused by vibration or external force, thereby ensuring the accuracy and consistency of tablet pressing.

[0026] Please see Figure 1 and Figure 5The cleaning assembly 9 includes a cleaning cylinder 91, a collection box 97, and a suction fan 98. The cleaning cylinder 91 is fixedly installed on the left and right sides inside the housing 1. A suction cover 92 is fixedly installed on the front side of the cleaning cylinder 91. A suction port 93 is opened on the top of the suction cover 92. A slot 94 is opened inside the suction port 93. A card plate 95 is movably engaged inside the slot 94. A cleaning brush 96 is fixedly installed on the top of the card plate 95. The collection box 97 and the suction fan 98 are both fixedly installed on the rear side of the housing 1. 98 is fixedly connected to the bottom of the collection box 97. A hose 99 is fixedly connected between the collection box 97 and the suction hood 2 92. The cleaning cylinder 91 drives the suction hood 2 92 to move forward. The cleaning brush 96 is close to the outside of the lower pressing groove 23. The top block 25 pushes out the remaining powder inside. The cleaning brush 96 cleans the powder at the bottom of the pressing component 2. The suction generated by the suction fan 98 draws the powder into the hose 99 through the suction port 93 and finally sends it to the collection box 97, thereby ensuring the full collection of residual powder.

[0027] The cleaning brush 96 is attached to the bottom of the pressing component 2. During the cleaning process, the bristles of the cleaning brush 96 are fine and soft, which can effectively remove the powder attached to the bottom of the pressing component 2, and avoid scratching or damaging the surface of the pressing component 2.

[0028] The suction hood 7 is located inside the housing 1 and is arranged symmetrically on the left and right. The suction hood 7 is connected to the collection box 97 through a pipeline. A filter screen is installed on the top of the suction hood 7 to prevent tablets from falling in. When a tablet falls onto the suction hood 7, it rolls down along the suction hood 7. Excess powder is sucked in by the suction hood 7 and sent to the collection box 97 for collection.

[0029] Please see Figure 1 and Figure 2 Inside the shell 1, at the bottom, there is a movable receiving drawer 8. When the tablets fall onto the suction hood 7, they roll down the suction hood 7 and are collected in the receiving drawer 8.

[0030] Working principle: When in use, the medicine powder is put into the upper pressing groove 23. Then, the pressing cylinder 4 drives the slide plate 5 to descend, so that the pressing rod 6 at the bottom of the slide plate 5 presses the medicine powder in the pressing groove 23 into tablets. Then, the pressing cylinder 4 drives the slide plate 5 to return to its original position. The flipping motor 3 drives the pressing assembly 2 to flip 180 degrees, so that the upper pressing groove 23 flips to the bottom, so that the tablets inside fall onto the suction hood 7. The weight of the sliding seat 24 drives the top block 25 on its outside to slide downward in the pressing groove 23, pushing the tablets stuck in the pressing groove 23 outward, avoiding the tablets being stuck in the pressing groove 23 and making them difficult to remove, thus improving the convenience of use.

[0031] After the tablet falls, the cleaning cylinder 91 drives the suction hood 92 to move forward, so that the cleaning brush 96 is attached to the outer wall of the pressing groove 23 below. When the tablet is pushed out of the pressing groove 23 by the top block 25, the residual powder inside is pushed outward. The cleaning brush 96 cleans the powder under the pressing assembly 2, and the suction fan 98 generates suction to suck the powder into the hose 99 through the suction port 93 and send it into the collection box 97. The tablet falls onto the suction hood 7 and rolls down into the collection drawer 8 for collection. Excess powder is sucked in by the suction hood 7 and sent to the collection box 97 for collection. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] 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.
