Description

Technical Field

[0001] The present invention belongs to the technical field of packaging, and particularly relates to a bagging device for raw drugs with a sorting function. Background Art

[0002] Sorting and then bagging raw drugs is mainly to ensure quality, facilitate use and ensure safety. During the production process, foreign matters may be mixed into the raw drugs or there may be problems such as uneven particle size. Sorting can remove impurities and control the particle size to meet the process requirements of different dosage forms. For example, injectables require finer particles to avoid risks, thereby ensuring the drug efficacy and medication safety. According to the requirements of downstream enterprises, the raw drugs are accurately metered and bagged according to specific specifications, which not only facilitates pharmaceutical enterprises to directly weigh and feed according to the formula, improving production efficiency, but also facilitates warehouse classification storage and protects the drugs through moisture-proof, light-proof and other packaging methods during transportation, preventing them from being affected by moisture, oxidation or pollution during storage and transportation, and meeting the Good Manufacturing Practice for Drugs.

[0003] The sorting functions of existing raw drug bagging devices generally have structural defects. Traditional devices mostly use single-layer sieve meshes or fixed-aperture sorting structures, which cannot achieve fine grading of raw drug particles. When dealing with drug particles with small particle size differences, the sorting error rate of existing devices is relatively high, resulting in mixed specifications of finished drugs and making it difficult to meet the requirements of high-quality production. Most devices rely on multiple motors to independently drive each sorting link, which not only increases the energy consumption of the device, but also increases the failure rate due to complex mechanical linkages. Frequent shutdowns for maintenance affect production continuity. The sorting, cleaning and bagging links of existing devices are independent of each other and lack a coordinated control mechanism. Therefore, researching and developing an automated device integrating efficient sorting, intelligent cleaning and linkage bagging has become a technical problem urgently to be solved in the industry.

The number of the storage and feeding hoppers is three, which are respectively installed below the three areas of the fine screening drum, and the storage and feeding hoppers are for quantitative feeding and automatically open in a hopper shape when storing a certain weight of medicine.

[0008] As a preferred embodiment of the present invention, further, it further includes a bag supporting mechanism.

[0010] The beneficial effects of the present invention are as follows: The fine sorting mechanism forms a multi-stage screening system of "primary screening + fine screening" through the cooperation of the conical first primary screening roller, the second primary screening roller and the fine screening drum. The primary screening roller uses the conical structure to make the raw drugs fall in sequence from small to large in diameter. The fine screening drum further accurately separates drugs of different specifications through large, medium and small caliber sieve holes (the first sieve hole, the second sieve hole, the third sieve hole) set in zones, ensuring that the raw drugs with large, medium and small diameters respectively fall into the corresponding areas, realizing fine sorting, avoiding manual intervention, and improving the sorting efficiency and classification accuracy.

[0011] The cleaning mechanism drives the gear-link structure through the first motor to drive the brush body to reciprocate along the frame track, and can clean the raw drugs adhered to the surfaces of the first primary screening roller and the second primary screening roller in real time during the screening process, avoiding sieve hole blockage or material residue. After the equipment work is completed, it can also automatically complete the cleaning operation, reduce the manual maintenance cost, ensure the long-term efficient operation of the screening device, and improve the reliability of the equipment.

[0012] The storage and blanking hopper is designed for quantitative blanking. It automatically opens when the drug weight reaches the standard, and cooperates with the corresponding bag-supporting mechanism below. The arc claw block is driven by a telescopic cylinder to drive the support bar to expand the bag mouth, ensuring that drugs of different specifications accurately fall into the bag and avoiding spillage. The three bag-supporting mechanisms share a driving motor and a through rod, with a compact structure, saving energy and space, and realizing the efficient linkage of "one motor driving multiple workstations". This not only improves the degree of bagging automation but also ensures that the bagging weights of drugs of various specifications are consistent through quantitative control, facilitating subsequent packaging and management.

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1 like Figures 1 - 6 As shown, this embodiment proposes a raw material drug bagging device with a sorting function, including a fine sorting mechanism 1, the fine sorting mechanism 1 includes a baffle plate 101, a first transmission belt 102, a first rotating rod 103, a first bevel gear 104, a second bevel gear 105, a support plate 106, a second rotating rod 107, a second transmission belt 108, a third rotating rod 109, a third transmission belt 110, a fourth rotating rod 111, a fourth transmission belt 112, a fifth rotating rod 113, a first primary screening roller 114, a second primary screening roller 115, a fine screening drum 116, a support rod 117, a first sieve hole 118, a second sieve hole 119 and a third sieve hole 120, and the fine sorting mechanism 1 is installed in a frame 5; The first primary screening roller 114 and the second primary screening roller 115 are both conical and arranged in parallel at the upper part within the frame 5. The fourth rotating rod 111 and the fifth rotating rod 113 penetrate through the frame 5 and are fixedly inserted at one end of the first primary screening roller 114 and the second primary screening roller 115. The fourth rotating rod 111 and the fifth rotating rod 113 are rotatably installed on the frame 5, so the first primary screening roller 114 and the second primary screening roller 115 are also rotatably installed on the frame 5. The third rotating rod 109 is rotatably installed below the fourth rotating rod 111 and the fifth rotating rod 113. One side of the fine screening drum 116 is fixedly installed on the third rotating rod 109. The support rod 117 is fixedly installed on the other side of the fine screening drum 116, and the support rod 117 is also rotatably installed on the frame 5. The two partition plates 121 divide the fine screening drum 116 into three regions. The first sieve holes 118, the second sieve holes 119, and the third sieve holes 120 are respectively opened on these three regions. The first sieve holes 118 are large-diameter sieve holes, the second sieve holes 119 are medium-diameter sieve holes, and the third sieve holes 120 are small-diameter sieve holes. The fine screening drum 116 is rotatably installed directly below the first primary screening roller 114 and the second primary screening roller 115. The baffle plates 101 are arranged on both sides of the fine screening drum 116 for isolating a feeding channel. The support plate 106 is fixed to the rear side of the frame 5. The second rotating rod 107 is rotatably installed on the support plate 106. The fourth transmission belt 112 covers the fourth rotating rod 111 and the fifth rotating rod 113. The second transmission belt 108 covers the second rotating rod 107 and the third rotating rod 109. The second bevel gear 105 is fixedly sleeved on the second rotating rod 107. The first rotating rod 103 is rotatably installed on the rear side of the frame 5 and is located on one side of the second bevel gear 105. The first bevel gear 104 is fixedly sleeved on the first rotating rod 103. The first bevel gear 104 and the second bevel gear 105 are meshed with each other.

[0018] It should be noted that both the first primary screening roller and the second primary screening roller adopt conical structures and are arranged in parallel. The axial distance between the two rollers gradually increases from the feeding end to the discharging end, forming a gradient screening gap that increases from small to large. (The end close to the fourth rotating rod is the feeding end). The gap at the feeding end is the smallest, allowing only small-particle-size materials to pass through. The gap in the middle region is moderate, allowing medium-particle-size materials to pass through. The gap at the discharging end is the largest, allowing large-particle-size materials to pass through.

[0019] In this embodiment, when raw drugs need to be sorted, the operator first pours the raw drugs into the feeding end between the first primary screening roller 114 and the second primary screening roller 115, and then starts the first motor 208. The first motor 208 drives the first transmission belt 102 to rotate, the first transmission belt 102 drives the first rotating rod 103 to rotate, the first rotating rod 103 drives the first bevel gear 104 to rotate, the first bevel gear 104 drives the second bevel gear 105 to rotate, the second bevel gear 105 drives the second rotating rod 107 to rotate, the second rotating rod 107 drives the second transmission belt 108 to rotate, the second transmission belt 108 drives the third rotating rod 109 to rotate, the third rotating rod 109 drives the third transmission belt 110 to rotate, the third transmission belt 110 drives the fifth rotating rod 113 to rotate, the fifth rotating rod 113 drives the fourth transmission belt 112 to rotate, the fourth transmission belt 112 drives the fourth rotating rod 111 to rotate. Further, the fourth rotating rod 111 drives the first primary screening roller 114 to rotate, and the fifth rotating rod 113 drives the second primary screening roller 115 to rotate. Subsequently, the raw drugs between the first primary screening roller 114 and the second primary screening roller 115 fall into the lower fine screening drum 116 in ascending order. The raw drugs with small diameters fall into the third sieve holes 120, those with medium diameters fall into the second sieve holes 119, and those with large diameters fall into the first sieve holes 118, thus completing the preliminary screening of the raw drugs. The start of the first motor 208 also drives the rotation of the third rotating rod 109. The third rotating rod 109 naturally drives the fine screening drum 116 to rotate. When the fine screening drum 116 rotates, the raw drugs of the three diameters fall into the sieve holes, and after tumbling, finally fall into the storage and blanking hopper 4, thus completing the fine sorting of the raw drugs.

[0020] Embodiment 2 As Figures 1 - 6 shown, the present invention also proposes that it further includes a cleaning mechanism 2. The cleaning mechanism 2 includes a frame track 201, a first gear 202, a second gear 203, a slider 204, an extension rod 205, a brush body 206, a bracket 207, a first motor 208, a first connecting plate 209, a first rotating shaft 210, a second rotating shaft 211, a second connecting plate 212, and a third rotating shaft 213; The frame rail 201 is fixed to the top of the frame 5.

One end of the first connecting plate 209 is rotatably installed on the first rotating shaft 210. The second rotating shaft 211 is rotatably installed at the other end of the first connecting plate 209. One end of the second connecting plate 212 is rotatably installed on the second rotating shaft 211. The second gear 203 is installed on the second rotating shaft 211. The third rotating shaft 213 is rotatably installed at the other end of the second connecting plate 212. The first gear 202 is installed on the third rotating shaft 213.

[0021] In this embodiment, when the first motor 208 is started, the first motor 208 also drives the third rotating shaft 213 to rotate. The third rotating shaft 213 drives the first gear 202 to rotate. The first gear 202 drives the second gear 203 to rotate. The second gear 203 drives the second connecting plate 212 to rotate along the third rotating shaft 213 towards the direction of the first rotating rod 103. At the same time, one end of the second connecting plate 212 drives one end of the first connecting plate 209 to move, so that the other end of the first connecting plate 209 moves along the slideway of the frame rail 201. Furthermore, the first connecting plate 209 drives the slider 204 to move within the frame rail 201. The slider 204 drives the extension rod 205 to move. The extension rod 205 then drives the brush body 206 to move. This is to better perform a preliminary screening of the raw medicine, prevent some raw medicine from adhering to the first primary screening roller 114 and the second primary screening roller 115, and also perform a cleaning operation on the first primary screening roller 114 and the second primary screening roller 115 after the work is completed.

The first expansion mechanism 311 and the second expansion mechanism 312 have the same structure. The U-shaped moving block 3111 is installed on the displacement belt 303. The connecting plate 3112 is fixed to one side of the U-shaped moving block 3111. The support frame 3117 is fixed to the connecting plate 3112.

[0024] The brush body 206 is a flexible component, and its length reaches the first primary screening roller 114 and the second primary screening roller 115.
