Abstract
The utility model relates to a nitrogen-filled packing control system which is used for controlling a process that a packing device fills nitrogen into a packing container. The nitrogen-filled packing control system comprises a feeding device and a discharging port of the feeding device is connected with the packing container. An inner cavity of the feeding device is communicated with a section of an air inlet-outlet pipeline, an air suction device is connected with the air inlet-outlet pipeline, and a nitrogen source is connected with the air inlet-outlet pipeline through an inflation valve. A transmission sensing device is arranged on the air inlet-outlet pipeline. A sensing signal of the transmission sensing device is transmitted to a control module. A controlling signal output by the control module respectively controls starting and stopping of the transmission sensing device and on-off of the inflation valve. The nitrogen-filled packing control system is simple in structure, convenient to control, capable of accurately controlling a dust absorption process and the nitrogen-filled process, improving quality of nitrogen-filled packing and reducing the waste of nitrogen.
Description
Technical field
The utility model belongs to packaging facilities, relates to a kind of nitrogen-filled packaging control system, is used for packaging facilities the process that the packing container inner chamber is filled with nitrogen is controlled.
Background technology
In packaging facilities, often adopt the packing container inner chambers such as packaging bag are vacuumized the shelf-life that prolongs packing material with the method for inflated with nitrogen.Packaging facilities for powdery or granular material, the nitrogen-filled packaging system generally includes the feeding machanism that outlet is joined with packing container (packaging bag etc.) and just material is sent into packing container (such as spiral conveyer etc.), also arrange in the system and be used for feeding machanism inner chamber and packing container are carried out the aspirator system of dust suction and exhaust, and be used for packing container is filled with the source nitrogen of nitrogen.In traditional Nitrogen filling system, air-breathing and fill the nitrogen process and can't accurately control, thus have a negative impact, for example: cause remaining oxygen too much affect the product maintenance phase; Dust suction does not thoroughly make the sealing clip powder, affects seal quality; Filling the excessive nitrogen that causes of nitrogen wastes.
Summary of the invention
Technical problem to be solved in the utility model is a kind of dust suction to be provided and to fill the nitrogen-filled packaging control system that the control of nitrogen pressure is accurate, can improve the nitrogen-filled packaging quality, save nitrogen.
Nitrogen-filled packaging control system of the present utility model includes the feeding device that a discharging opening is connected with packing container, the feeding device inner chamber is communicated with one section turnover air pipe, an aspirator system is connected with the turnover air pipe, and a source nitrogen is connected with the turnover air pipe by charge valve; Be provided with the conveying sensing device on the described turnover air pipe, carry the transducing signal of sensing device to send into a control module, the control signal of described control module output controls respectively the startup of aspirator system, stop and the opening and closing of charge valve.
For powdery or granular material, described feeding device can adopt conveyor screw.
Carry sensing device can adopt gas pressure sensor or flow sensor, can obtain gaseous tension or flow signal respectively, as the control foundation.
The utility model is simple in structure, control is convenient, by to pressure or flow monitoring air-breathing and inflation, can be exactly to dust suction with fill the nitrogen process and control, improved nitrogen-filled packaging quality, reduced the waste of nitrogen.
Description of drawings
Fig. 1 is the systematic schematic diagram of the utility model embodiment.
The specific embodiment
As shown in the figure, this nitrogen-filled packaging control system includes the feeding device 1 that a discharging opening is connected with packing container Q, the feeding device inner chamber is communicated with one section turnover air pipe 2, and an aspirator system 3 is connected with the turnover air pipe, and a source nitrogen 4 is connected with the turnover air pipe by charge valve 5; Be provided with on the turnover air pipe 2 and carry sensing device 6, carry the transducing signal of sensing device 6 to send into a control module 7.Carry sensing device to adopt gas pressure sensor, control module according to the detection signal output control signal of gas pressure sensor control respectively aspirator system startup, stop and the unlatching of charge valve, closing.For powdery or granular material, feeding device adopts conveyor screw.
The working process of the utility model embodiment is:
1, after feeding device 1 finishes to packing container Q attal, control module 7 starts first 3 pairs of packing container inner chambers of aspirator system and carries out dust suction and discharge air;
2, after gas pressure sensor detects negative pressure in the pipeline and reaches setting value, stopped suction by control module control aspirator system, open simultaneously charge valve 5, fill nitrogen by 4 pairs of packing containers of source nitrogen;
3, after the gaseous tension sensing detection reaches setting value to the inflation pressure in the pipeline, closed by control module control charge valve, simultaneously packing container is carried out sealing operation.
