Description

Technical Field

[0001] The utility model relates to the technical field of ampoule sealing mechanisms, and particularly relates to a sealing mechanism for ampoule production. Background Art

[0002] An ampoule refers to a fusible hard glass container, which is commonly used to store injectable drugs, vaccines, sera, etc. There are generally two types: straight neck and curved neck, with a capacity of generally 1 - 25 ml. It is commonly used for injectable liquid medications and also for the packaging of oral liquids.

[0003] During the production process of ampoules, a sealing process is required at the end. The sealing mechanism for ampoule production generally holds and seals the heated and melted ampoule mouth through several jaw assemblies, and then separates the clamped and cut head part from the ampoule. However, currently, in order to ensure that after cutting, the separated part of the ampoule head does not fall on the ampoule track, therefore, an inclined pushing device is also required for cooperation, and the sealing mechanism is also installed obliquely. The ampoule is pushed obliquely by the inclined pushing device and then cooperates with the sealing mechanism, so as to avoid the separated part of the ampoule head from falling on the ampoule track. However, this structure requires the installation of an inclined pushing device, thus increasing the cost. At the same time, there are additional steps of inclined pushing and resetting, thereby reducing the production efficiency.

Air nozzles 5 are arranged in the mounting holes of the inclined plate 403. The air nozzles 5 correspond to the jaw assemblies 2 one by one. The air outlet directions of the air nozzles 5 face the clamping jaws 202 of the corresponding jaw assemblies 2. A through groove 404 is formed in the horizontal plate 401. The through groove 404 of the horizontal plate 401 corresponds to the inner cavity 6 of the outer shell 1. The ejector rods 203 pass through the through groove 404 of the horizontal plate 401 to ensure that when the angle of the ejector rods 203 changes during lifting, the horizontal plate 401 will not be impacted. A reinforcing plate 405 is arranged at the connection between the horizontal plate 401 and the vertical plate 402 to ensure the structural strength of the L-shaped hanging plate 4 and avoid bending deformation at the connection between the horizontal plate 401 and the vertical plate 402.

[0029] Installation method and operating principle: First, insert the jaw assembly 2 into the inner cavity 6 of the housing 1 and fasten it with bolts. Then, connect the horizontal plate 401 of the L-shaped hanging plate 4 to the extension block 7 of the housing 1 and the bent plate 12 with bolts. At this time, the ejector rod 203 of the jaw assembly 2 passes through the through hole of the horizontal plate 401. Next, install the air nozzle 5 at the installation hole of the inclined plate 403 with nuts. At this time, the air outlet direction of the air nozzle 5 faces the middle position between the two clamping jaws 202 at the bottom of the corresponding jaw assembly 2. Then, connect the connecting sleeve 207 to the top of the top plate, and then rotatably connect the pressing plate 3 to the side plates 11 on both sides of the upper surface of the extension block 7 through the convex shaft. At the same time, rotatably connect the top end of the ejector rod 203 to the first support plate 13 through the pin, connect the bottom end of the ejector rod 203 to the second support plate 207 at the top of the rack block 204 through the pin, and finally rotatably connect the cylinder 10 to the third support plate 14 at the upper part of the L-shaped rod 9 through the pin, and connect the piston rod of the cylinder 10 to the fourth support plate 15 of the pressing plate 3 through the pin to complete the assembly. Before use, cooperate with the external guide rod through the connecting block 8, and the bottom of the connecting block 8 cooperates with the external cylinder body, so that the whole is lifted and lowered. The air nozzle 5 is connected to the air pump through a trachea, and the air nozzle 5 realizes blowing outwards. When in use, after the ampoule is filled with liquid and moved to the sealing mechanism, the ampoule is aligned with each jaw assembly 2. The sealing mechanism descends, and the clamping jaws 202 of the jaw assembly 2 are located on both sides of the corresponding ampoule bottle mouth. The piston rod of the cylinder 10 pushes, so that one end of the pressing plate 3 away from the cylinder 10 is lifted, thereby driving the ejector rod 203 to rise. The ejector rod 203 drives the rack block 204 to rise. The teeth of the rack block 204 cooperate with the toothed disc 205, and the toothed disc 205 drives the clamping jaws 202 to move closer to the middle, so as to clamp and seal the melted ampoule bottle mouth. The disconnected part is clamped by the two clamping jaws 202. The clamping mechanism rises, and at the same time the air nozzle 5 blows air. The clamping jaws 202 open, and the disconnected part of the ampoule bottle is blown away from the air nozzle 5 by the air outlet of the air nozzle 5 and falls on the collection slope, so as to prevent the disconnected part of the ampoule bottle from falling on the ampoule bottle track. The structure of the present utility model is reasonable. The upper part of the housing 1 is connected to the L-shaped hanging plate 4. Several air nozzles 5 are installed on the inclined plate 403 of the L-shaped hanging plate 4, and the air nozzles 5 correspond to the clamping jaws 202 of the corresponding jaw assembly 2. When sealing the ampoule bottle, after the clamping jaws 202 of the jaw assembly 2 clamp and separate the disconnected part of the ampoule bottle mouth, through the guiding air outlet of the air nozzle 5, after the clamping jaws 202 open, the disconnected part of the ampoule bottle mouth can be blown away from the ampoule bottle track, preventing the disconnected part of the ampoule bottle from being directly on the ampoule bottle track. In this way, there is no need to additionally set an inclined pushing assembly, and the sealing mechanism can be directly installed directly above the ampoule bottle track, making the structure simpler and improving the production efficiency at the same time.
