Description

Technical Field

[0001] The utility model relates to a quantitative packaging device for tablet production, belonging to the technical field of medicine packaging. Background Art

[0002] In the process of drug production, the packaging link is an indispensable part. The traditional tablet packaging method mainly relies on manual operation, which has the disadvantages of low efficiency, poor precision, and high labor intensity. After searching, it was found that the Chinese patent with the announcement number CN207060905U disclosed a drug dispenser. In this patent, the medicine to be dispensed is poured into the medicine storage tank, and the medicine is dried through the drying slot cover and the drying slot on the end cover. The equipment is started to rotate the medicine measuring shaft, and the medicine enters the medicine taking slot on the medicine measuring shaft under the action of gravity and the rotation of the medicine measuring shaft; the medicine measuring shaft rotates to the top of the medicine outlet slot, and the medicine falls into the dispensing box, the pulley slides, and the dispensing box is sent to the next station, and the new empty dispensing box is automatically sent to the bottom of the medicine outlet slot. However, when one dispensing box is full, the other dispensing box rotates to the medicine outlet slot. Since there is no dispensing box fixing mechanism, it is impossible to judge whether the second dispensing box or even the subsequent dispensing box is aligned with the medicine outlet slot. If it is not aligned, it will cause the medicine to spill and affect the dosage. Summary of the invention

[0038] The weighing device may specifically be the following structure, including a lifting drive member 41, a weighing platform 42 and a weighing sensor 43. The lifting drive member 41 is arranged below the conveying frame 32. The weighing platform 42 is connected to the movable end of the lifting drive member 41. The weighing sensor 43 is arranged below the weighing platform 42. The weighing platform 42 is suitable for being flush with the bottom surface of the conveying trough when the lifting drive member 41 is in a lowered position. The second pushing mechanism is suitable for pushing the storage box 321 to slide onto the weighing platform 42. The weighing sensor 43 is suitable for detecting the weight of the storage box 321 on the weighing platform 42.

[0039] In this embodiment, the tablets can be salbutamol sulfate tablets, which are mainly used to treat respiratory diseases such as bronchial asthma or asthmatic bronchitis accompanied by bronchial spasm. The first pusher 22 can be an electric push rod, and the lifting drive member can be a cylinder. The quantitative plate 23 is also provided with a closed surface. When the first pusher 22 pushes the quantitative plate 23 to slide, it drives the quantitative groove 231 to move to the first drop port 211, and then the closed surface moves to the discharge port 121, closing the discharge port 121 to prevent tablets in the hopper 12 from falling.

[0040] Specifically, Figure 1 As shown, the quantitative device further includes an auxiliary plate 24, which is installed between the quantitative base 21 and the quantitative plate 23. The auxiliary plate 24 is provided with a second drop opening 241, which corresponds to the first drop opening 211. In this embodiment, the auxiliary plate 24 mainly assists the quantitative plate 23 in sliding to perform quantitative control and transport tablets.

[0041] Specifically, Figure 6 As shown, the quantitative device further includes a blanking cylinder 25 , which is provided with a blanking channel 251 . The blanking cylinder 25 is mounted on the quantitative base 21 , and the blanking channel 251 corresponds to the first blanking opening 211 .

[0042] In this embodiment, the blanking barrel 25 and the blanking channel 251 can effectively guide the tablets into the quantitative device from the first blanking port 211, ensuring that the material can fall smoothly and accurately into the storage box 321, and avoid scattering outside the storage box 321 due to the high altitude drop.

[0043] Specifically, Figure 3 As shown, the quantitative plate 23 is slidably mounted on the quantitative base 21 through at least one first guide rail slider pair; wherein,

[0044] The first guide rail slider pair includes:

[0045] A first guide rail 51 mounted on the quantitative base 21;

[0046] A first slide block 52 is mounted on the quantitative plate 23 .

[0047] Specifically, Figure 4 As shown, a scraper 121A is installed at the discharge port 121, and the scraper 121A is suitable for scraping off the tablets at the discharge port 121. In this embodiment, the scraper 121A can help remove the tablets at the discharge port 121, so that subsequent tablets can be smoothly discharged from the mold, reduce blockage during the tablet discharging process, and ensure the sliding of the quantitative plate 23.

[0048] Specifically, Figure 2As shown, the second pushing mechanism can specifically be the following structure, including a pushing bracket 311, a second pushing member 312 and a pushing plate 313, the pushing bracket 311 is arranged opposite to the conveying bracket 32, the second pushing member 312 is installed on the pushing bracket 311, the pushing plate 313 is slidably fitted on the pushing bracket 311, and the second pushing member 312 is connected to the pushing plate 313.

[0049] In this embodiment, the pushing plate 313 can evenly push the storage box 321 to move in the conveying groove, and the second pushing member 312 can be started. By pre-setting the second pushing member to push a fixed stroke in a single time, it is ensured that the tablets can accurately fall into the storage box 321, avoiding the storage box 321 from not being able to accurately face the drop channel 251 due to inconsistent pushing stroke.

[0050] Specifically, Figure 2 As shown, the push plate 313 is slidably mounted on the push bracket 311 through at least one second guide rail slider pair; wherein,

[0051] The second guide rail slider pair includes:

[0052] A second guide rail 61 mounted on the push bracket 311;

[0053] The second slider 62 is mounted on the push plate 313 .

[0054] Specifically, the tablet production quantitative packaging device further includes a control module, which is suitable for receiving weight information from the weighing sensor 43 to control the actions of the first pushing member 22 , the second pushing member 312 and the lifting driving member 41 .

[0055] In this embodiment, the control module is a single chip microcomputer, which is a prior art.

[0056] In this embodiment, the tablets in the hopper 12 fall into the quantitative groove 231 through the discharge port 121 (the capacity of the quantitative groove 231 is the preset weight of a storage box 321), and the control module controls the first pusher 22 to push the quantitative plate 23 to move, so that the quantitative plate 23 drives the tablets in the quantitative groove 231 to align with the first drop port 211, and the tablets fall into the storage box 321 through the drop barrel 25;

[0057] The control module controls the second pushing mechanism to move an empty storage box 321 to the bottom of the blanking barrel 24 and push the filled storage box 321 onto the weighing platform 42. The weighing sensor 43 detects the weight change of the storage box 321 and transmits the weight information to the control module. The control module determines whether to continue filling according to the weight result.

[0058] If the storage box meets the preset weight at this time, the control module drives the lifting drive 41 to lift the storage box 321, and the operator takes out the cover. At this time, the weighing sensor 43 transmits the weight information of the weight on the weighing platform 42 as 0 to the control module, and the control module drives the lifting drive 41 to lower the weighing platform 42 to the initial position for the next round of operation;

[0059] If the storage box 321 does not meet the preset weight at this time, the control module reminds the operator to replenish it through a prompt device (such as an alarm). After replenishing to the preset weight, the control module drives the lifting drive member 41 to lift the storage box 321.

[0060] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
