Description

A feeding transmission device for ampoule bottle sterilization and baking

Technical Field

The invention relates to the technical field of medicine filling devices, in particular to a feeding and conveying device used for sterilizing and baking ampoules.

Background Art

An ampoule is a hard glass or plastic container that can be melted and sealed, and is commonly used to store injectable drugs, vaccines, serums, etc. The ampoule needs to be sterilized before filling. The sterilization process is as follows: the conveyor belt assembly transports the ampoule on it through a tunnel-type sterilization baking oven. The internal components of the sterilization baking oven are first sterilized by high-temperature steam, and then the moisture generated by the high-temperature steam is removed by high-temperature baking. The conveyor mesh belt assembly is a conveying device using a metal woven mesh as a conveyor belt, and a bridge plate needs to be set up between the end of the conveyor mesh belt assembly and the feeding device (usually a disc feeding device). The baffle structures on both sides of the bridge plate of the current ampoule bottle baking feeding transmission device are usually rigid baffles. The ampoules on the bridge plate are squeezed by each other to achieve movement toward the conveyor mesh belt assembly. During the squeezing and movement of the ampoules on the bridge plate, the ampoules are prone to get stuck between the ampoules, resulting in excessive squeezing force between the ampoules and causing the bottle to break. At the same time, the feeding process of the feeding device is intermittent, and the conveyor mesh belt assembly needs to be started and stopped manually to coordinate with the feeding rhythm of the feeding device.

DETAILED DESCRIPTION

In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 3, a feeding and conveying device for ampoule sterilization and baking of the present invention includes an outer shell 1, a bridge plate 2, a conveyor mesh belt assembly and a pressure switch assembly for controlling the start and stop of the conveyor mesh belt assembly.

A feed port 21 is provided at the end of the outer shell 1, and a bridge plate 2 is fixedly installed on the inner wall of the outer shell 1. The feed port 21 is opposite to the feeding device. In this embodiment, the feeding device is a disc feeding device, which continuously transports the ampoule bottles to be sterilized from the feed port 21 to the bridge plate 2 in the outer shell 1. The conveyor mesh belt assembly is located in the outer shell 1, and the conveyor mesh belt assembly passes through the tunnel-type sterilization baking box. The conveyor mesh belt assembly includes a metal conveyor belt 3 and a driving module for driving the metal mesh belt 3; the metal conveyor belt 3 is a metal woven mesh structure, and a conveyor chain is provided on the outer side thereof, and a conveyor sprocket engaged with the conveyor chain is provided in the conveyor chain. The driving module (usually a driving motor) is used to drive the conveyor sprocket to rotate, thereby driving the metal mesh belt 3 to operate. The structure of the conveyor mesh belt assembly and the feeding assembly are prior art, and the present invention does not introduce their specific structures in detail. One end of the bridge plate 2 is connected to the inner wall of the outer shell 1 and is connected to the feed port 21, and the other end of the bridge plate 2 extends to the upper surface of the metal mesh belt 3.

A fixed limit plate 4 and a rotating limit plate 41 are respectively provided on both sides of the bridge plate 2. The end of the fixed limit plate 4 is welded to the inner wall of the outer shell 1, and the end of the rotating limit plate is rotatably connected to the edge of the feed port 21 through a hinge. The ampoule bottle 9 entering the feed port 21 is located between the fixed limit plate 4 and the rotating limit plate 41.

The pressure switch assembly includes a pressure switch 7, a trigger baffle 5, a rotating shaft and a reset elastic member 63. The pressure switch 7 is fixed to the outer wall of the outer shell 1. The trigger baffle 5 is located outside the rotating limit plate. The end of the trigger baffle 5 is fixedly connected to the rotating shaft 5. A trigger block 62 is also provided at the lower end of the rotating shaft 5. One end of the reset elastic member 63 is connected to the trigger block 62, and the other end is connected to the outer wall of the outer shell 1. The pressure switch 7 is connected to the driving module of the conveyor mesh belt assembly through a wire 74. When the ampoule bottle 9 on the limit plate is full, the ampoule bottle 9 located on the side squeezes the rotating limit plate 41 and drives the trigger baffle 5 to rotate outward, thereby driving the rotating shaft to rotate, and then driving the trigger block to trigger the pressure switch 7. The pressure switch 7 sends an operation signal to the driving module of the conveyor mesh belt assembly to make the conveyor mesh belt assembly run.

Preferably, a rotating fixed block 61 is fixedly provided on the outer wall of the outer shell 1, and a rotating hole penetrating the rotating fixed block 61 is provided on the rotating fixed block 61, and the rotating shaft is rotatably arranged in the rotating hole through a rotating bearing, and the end of the trigger baffle 5 is connected to the upper end of the rotating shaft, and the trigger block is fixedly connected to the lower end of the rotating shaft. A mounting plate 71 is also fixedly provided on the outer wall of the outer shell 1, and the mounting plate 71 is located below the rotating fixed block 61, and the pressure switch 7 is fixed on the mounting plate 71. Specifically, an arc-shaped mounting groove 72 is provided on the mounting plate 71, and a threaded sleeve 75 is provided below the pressure switch 7, and the outer wall of the threaded sleeve 75 is provided with an external thread, and the threaded sleeve 75 is located in the mounting groove 72, and two fixing nuts 73 are provided on the threaded sleeve 75, and the two fixing nuts 73 are respectively located above and below the mounting plate 71, and the two fixing nuts 73 clamp the mounting plate 71, thereby fixing the pressure switch 7, and the mounting groove 72 ensures that the mounting position of the pressure switch 7 on the mounting plate 71 can be conveniently adjusted. The wire 74 at the lower end of the pressure switch 7 passes through the threaded sleeve 75, one end of the wire 74 is connected to the pressure switch 7, and the other end is connected to the driving module of the conveyor belt assembly. In this embodiment, the reset elastic member 63 is an elastic metal sheet bent into an arc. In this embodiment, the reset elastic member 63 is a spring steel sheet structure. The spring steel has good toughness. After the spring steel is bent into an arc-shaped sheet structure, both ends of the spring steel have a reset elastic force after being squeezed and stretched.

Preferably, a mounting sleeve is respectively provided at both ends of the reset elastic member 63, the trigger block and the outer wall of the outer shell 1 are respectively provided with mounting rods, and the mounting sleeves at both ends of the reset elastic member 63 are respectively sleeved on the mounting rods.

Preferably, the end of the rotation limit plate 41 away from the rotation axis is also hinged with a limit baffle 51, and the limit baffle 51 extends to the metal mesh belt 3. The limit baffle 51 ensures that the ampoule bottle 9 on the bridge plate 2 moves toward the middle of the metal mesh belt 3, ensuring that the ampoule bottle 9 on the metal mesh belt 3 is concentrated in the middle.

Preferably, the bridge plate 2 is made of stainless steel with a smooth surface, which can reduce the resistance of the ampoule bottle 9 moving thereon and reduce the possibility of the ampoule bottle 9 being squeezed and ruptured. The bridge plate 2 is provided with a plurality of strip slits for allowing ampoule bottle fragments to fall off. The strip slits can allow the fragments to fall from the bridge plate 2 after a small number of ampoule bottles 9 rupture, thereby preventing the problem of ampoule bottle fragments causing other bottles to get stuck.

The working principle of the feeding and conveying device for sterilizing and baking ampoules of the present invention is as follows: the ampoules 9 are continuously fed from the feeding port 21 to the bridge plate 2 in the outer shell 1 under the feeding action of the disc feeding device; the number of ampoules 9 on the bridge plate 2 gradually increases, and some ampoules 9 are moved to both sides. When there are enough ampoules 9 on the bridge plate 2 (at this time, the ampoules 9 fill the space between the fixed limiting plate 4 and the rotating limiting plate 41 on the bridge plate 2, and part of them overflow onto the metal mesh belt 3), the ampoules 9 squeeze the rotating limiting plate 41. , the rotating limit plate 41 rotates outward to squeeze the trigger baffle 5, the trigger baffle 5 overcomes the elastic force of the reset elastic member 63 to drive the rotating shaft and the trigger block connected to the rotating shaft to rotate, the trigger block squeezes the pressure switch 7, and the pressure switch 7 is squeezed by the trigger block. After sending an operation signal to the drive module of the conveyor mesh belt assembly through the wire 74, the drive module starts and drives the metal mesh belt 3 to operate, thereby moving the ampoule bottle 9 squeezed onto the metal mesh belt 3 to the sterilization baking box 8, so that the ampoule bottle 9 passes through the sterilization baking box 8 to complete the sterilization baking process.

When the disc feeding device stops feeding, the number of ampoules 9 on the bridge plate 2 decreases, the squeezing effect of the ampoules 9 on the trigger baffle 5 disappears, the elastic reset member drives the rotating shaft and the trigger baffle 5 to reset, the pressure of the trigger block on the pressure switch 7 disappears, and the drive module automatically stops working.

During the above process, the trigger baffle 5 provides elastic force through the elastic reset member. When there are enough ampoules 9 on the bridge plate 2, the trigger baffle 5 rotates outward, which can reduce the excessive extrusion pressure between the ampoules 9 and the phenomenon that the ampoules 9 are squeezed and broken. At the same time, the trigger baffle 5 can automatically start the conveyor mesh belt assembly after the bridge plate 2 is full of bottles, thereby realizing automatic loading of the sterilization and baking box 8, and the elastic reset member can automatically interrupt the running signal after the disc feeding device stops feeding, so that the conveyor mesh belt assembly stops working, realizing the automatic start and stop of the conveyor mesh belt assembly, and reducing the manpower required for the sterilization and baking process of the ampoules 9.
