Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and specifically relates to a small granule packaging device for laboratory use. Background Art

[0002] Granules are dry granular preparations with a certain particle size made by mixing drug powders with suitable excipients. The particle size range specified in the Chinese Pharmacopoeia is that the total of coarse particles larger than sieve No. 1 (2000 μm) and fine particles smaller than sieve No. 5 (180 μm) should not exceed 15%.

[0003] During the research and development process of drugs, it is necessary to conduct stability studies on drugs according to the proposed market packaging. For granules, stability experimental studies need to be carried out after packaging. Since the sample amount used in experimental studies is small, therefore, during the research and development process of granules, the existing packaging methods are mostly to manually put granules of a set weight into a packaging bag, and then use a packaging bag sealing mechanism to seal the bag, so as to achieve the packaging of granules. Manual bagging ensures that the weight of each bag of granules is consistent. However, when manually putting the packaging bag filled with granules into the packaging bag sealing mechanism for sealing, the packaging bag may slip out of the hand, affecting the packaging efficiency.

[0008] In order to facilitate the drying of the stored granule agent, further, a heating frame is arranged in the storage cylinder.

[0009] In order to facilitate the breaking up of the caked granule agent, further, a stirring rod is rotatably connected in the storage cylinder, and a second motor for driving the stirring rod to rotate is arranged at the upper end of the storage cylinder.

[0010] In order to facilitate the taking out of the packaging bag, furthermore, a baffle is connected to the placing box by a hinge.

[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art: Through the alternating switching of the first electromagnetic valve and the second electromagnetic valve and the movement of the heat-sealing plate, the utility model realizes the integration of filling the granule agent into the packaging bag and sealing the packaging bag, avoids the situation of the packaging bag slipping off during sealing, and effectively improves the packaging efficiency.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model. Embodiment 1

[0021] Refer to Figures 1 - 5 , a small-scale granule packaging device for laboratory use, including a material storage cylinder 1, a feeding hopper 102 is provided on the material storage cylinder 1, the lower end of the material storage cylinder 1 is connected to a quantitative tube 4, a first solenoid valve 401 and a second solenoid valve 402 are arranged on the quantitative tube 4, support plates 101 are symmetrically arranged at the lower end of the material storage cylinder 1, a placing box 2 is arranged between the two support plates 101, heat-sealing plates 201 are symmetrically arranged in the placing box 2, a chute is provided on the placing box 2, a bi-directional lead screw 301 is rotated in the chute, moving blocks 302 are symmetrically threadedly connected to the bi-directional lead screw 301, and the moving blocks 302 are fixedly connected to the heat-sealing plates 201, and a first motor 3 for driving the bi-directional lead screw 301 to rotate is arranged on the placing box 2;

[0022] Moving grooves are symmetrically provided on the placing box 2, limiting plates 202 are slidably arranged in the moving grooves, the limiting plates 202 extend out of the moving grooves, third motors 6 are symmetrically arranged on the placing box 2, the output ends of the third motors 6 are fixedly connected with rotating lead screws 601, the rotating lead screws 601 extend into the moving grooves, and the rotating lead screws 601 are threadedly connected to the limiting plates 202;

[0023] A baffle 203 is hinged to the placing box 2.

[0024] When it is necessary to package the granules, the granules are poured into the material storage cylinder 1 through the feeding hopper 102, then the first solenoid valve 401 is opened, the granules fill the quantitative tube 4, the packaging bag is placed in the placing box 2, and the feeding port of the packaging bag is opened. At this time, the third motor 6 works, and the rotating lead screw 601 drives the limiting plate 202 to move and stick to the packaging bag, limiting the packaging bag and keeping the feeding port of the packaging bag open to prevent the feeding port from closing and affecting the filling of the granules into the packaging bag;

[0025] The first solenoid valve 401 is closed and the second solenoid valve 402 is opened. The granules of a fixed weight in the metering tube 4 fall and leave the metering tube 4 to be filled into the packaging bag. Then, the first motor 3 operates, the bidirectional lead screw 301 rotates, and the moving block 302 drives the heat-sealing plate 201 to move. The two heat-sealing plates 201 squeeze the feeding port of the packaging bag. When the feeding port of the packaging bag is closed, the heat-sealing plate 201 heats up to seal it. After the sealing is completed, the heat-sealing plate 201 moves back under the drive of the first motor 3. At this time, the rotating baffle 203 is rotated to take out the packaging bag filled with granules and place an empty packaging bag from the opening of the placement box 2. The second solenoid valve 402 is closed and the first solenoid valve 401 is opened, and the granules fill the metering tube 4 again, realizing the automatic quantitative packaging of the granules;

[0026] Through the alternating switching of the first solenoid valve 401 and the second solenoid valve 402, and the movement of the heat-sealing plate 201, the integration of filling the granules into the packaging bag and sealing the packaging bag is realized, avoiding the situation that the packaging bag slips off during sealing, and effectively improving the packaging efficiency.

[0028] A heating frame 103 is arranged in the storage hopper 1 to dry the granules in the storage hopper 1, avoiding the possible generation of bacteria due to the mixing of wet granules and dry granules, and the wet granules may stick to the inner wall of the metering tube 4 when entering the metering tube 4, resulting in inconsistent weight filled into the packaging bag with the specified weight.

[0029] A stirring rod 501 is rotatably connected in the storage hopper 1, and a second motor 5 for driving the stirring rod 501 to rotate is arranged at the upper end of the storage hopper 1. When the second motor 5 operates, it drives the stirring rod 501 to stir the granules in the storage hopper 1 to break up the agglomerated granules after drying, avoiding blocking the metering tube 4 and affecting the quality of the granules.
