The bottle discharging buffer cabin 8 is a hollow structure with openings at both ends. One end of the bottle discharging buffer cabin 8 is connected to the second partition door 5 via a sealing flange, and the other end is provided with a third partition door 9. A roller conveyor line 13 is provided on the outside of the third partition door 9. A gas circulation purification system 14 is connected to the bottle inlet buffer cabin 1, the empty bottle storage cabin 6, the packaging cabin 3, and the bottle discharging buffer cabin 8. The bottoms of the empty bottle storage cabin 6 and the packaging cabin 3 are each provided with an air inlet 22 and the tops are each provided with an exhaust port 23. Each of the air inlets 22 is connected to the air supply port of the gas circulation purification system 14 via a pipeline. Each of the exhaust ports 23 is connected to the air return port of the gas circulation purification system 14 via a pipeline. A dust removal filter 15 is connected to the packaging cabin 3. The dust removal filter 15 is mounted on the lower end bracket of the packaging cabin 3 and connected to the packaging cabin 3 via a pipeline.
[0035] Among them, the vertical screw filling machine 10 includes a material buffer cabin 16 embedded in the top of the packaging box, and a feeding servo motor 17 and a stirring reduction motor 18 are provided on the top of the material buffer cabin 16; a feeding port is provided on one side of the top of the material buffer cabin 16; a stirring device 19 is provided inside the material buffer cabin 16, and the stirring device 19 is connected to the stirring reduction motor 18 through a hollow shaft and a belt drive; a vertical feeding channel is provided at the bottom of the material buffer cabin 16, and a feeding screw 20 is provided in the feeding channel, and the feeding screw 20 is connected to the feeding servo motor 17 through a central axis passing through the hollow shaft; a docking device 21 adapted to the container opening is provided at the bottom of the feeding channel; a bottle body positioning device is provided on the top of the weighing tray of the electronic scale.
[0036] The first partition door 4, the second partition door 5 and the third partition door 9 are all composed of a door assembly that fits on the doorway. The door assembly includes: a pair of horizontally arranged slide rails 25, an actuator cylinder 26 parallel to the slide rails 25, and a door body 27 that fits on the slide rails 25 through a sliding sleeve and is connected to the telescopic end of the actuator cylinder 26. The fixed ends of the slide rails 25 and the actuator cylinder 26 are respectively fixed to the four sides of the doorway through brackets, and an annular inflatable airbag 28 is provided between the four sides of the doorway and the door body 27.
[0037] In the above arrangement, the packaging materials (packaging bottles / packaging bags) are first placed into the bottle inlet buffer cabin 1, and the bottle inlet buffer cabin 1 is closed by manually sealing the hatch 2. The gas circulation purification system 14 is started by the controller to evacuate the cabin and then replenish the purified inert gas. The packaging materials are then passed through the cabin outlet to the empty bottle storage cabin 6 for storage. The empty bottle storage cabin 6 can cache multiple packaging materials (packaging bottles / packaging bags) at a time to meet batch requirements. The empty bottle storage cabin 6 is separated from the packaging cabin 3 by a second partition door 5. After the packaging materials pass through, the second partition door 5 is closed and inflated and sealed to ensure that the water and oxygen content in the core area of the packaging cabin 3 is not destroyed. After the outer packaging material is fed, and the water and oxygen content of the box body meets the standard, the partition door is opened and packaging begins.
[0038] Specifically, during operation, the anhydrous oxygen weighing and packaging isolator implements the anhydrous oxygen weighing and packaging method through the following steps:
[0039] S1, through the packaging line, the packaging materials are sent in batches into the completely isolated bottle inlet buffer cabin 1;
[0040] S2, replacing the air in the bottle inlet buffer cabin 1 and the packaging cabin 3 with inert gas;
[0041] S3, using a vertical screw filling machine 10 to feed the material into the packaging material;
[0042] S4, the packaged products are sent in batches to the bottle discharge buffer cabin 8;
[0043] S5. The product batches in the bottle discharge buffer cabin 8 are transported to the roller conveyor line 13, thus completing the anhydrous oxygen weighing and packaging of the material.
[0044] During this process, the environment where the packaging material is located is isolated from the outside atmosphere. The air inside the isolator is replaced by inert gas. When the water and oxygen inside are reduced to a certain range, the gas purification circulation system of the isolator is turned on, and the residual water and oxygen in the box are removed through the purification column to reach a water and oxygen concentration of 1ppm. Weighing and packaging are then carried out in this independent and completely enclosed area.
[0045] The servo motor is controlled by the controller to enable the feeding screw 20 to feed the material, and at the same time, closed-loop control is performed with the weighing data of the electronic scale to ensure the weighing accuracy.
[0046] In summary, the anhydrous oxygen type weighing packaging isolator can not only ensure that the material does not come into contact with water and oxygen, but also ensure the personal safety of the operator. At the same time, it can also meet the requirements of continuous large-scale high-precision packaging, saving manpower and labor.
[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
