In the process of packaging foods in the packaging bags, the existing foods can be preserved in the packaging bags in order to keep the food fresh in the packaging. When the bag is filled with nitrogen and carbon dioxide, the food can be prevented from being corroded by the combination of the oxygen in the bag. The existing gas filling device is disposed on a package conveyor belt, and the filling gas device comprises a bracket and a plurality of jets. a tube, the bracket is disposed on the conveyor belt, the jet tubes are arranged on the bracket at intervals, and the jet tubes are connected to a gas supply unit, and the gas tubes inject the nitrogen and carbon dioxide into the air supplier The ends of the lances are sprayed into the interior of the packaging bag on the conveyor belt, so that when the food enters the packaging bag on the conveyor belt, the nitrogen in the packaging bag can fill the space in the packaging bag, and the carbon dioxide can be The oxygen in the package produces a chemical reaction, which in turn reduces the oxygen content in the package to achieve freshness preservation.

However, in the existing gas filling device, only the end of the nozzle of the lance, the nitrogen and carbon dioxide are concentrated at the end of the tube of the lance, which causes the gas pressure at the end of the tube to rise, and the gas is concentrated on the end of the tube of the lance. Will cause the gas ejection speed of the end of the jet tubes to be too fast, to blow up the items on the conveyor belt, and the staff member must suspend the operation of the conveyor belt to readjust the position of the article before proceeding, thereby causing the The problem of conveyor belt transport suspension.

The main purpose of this creation is to provide a gas filling device, in order to improve the existing gas filling device only the end of the jet of the jet tube, the gas pressure rises and the gas ejection speed is too fast, causing the articles on the conveyor belt to be blown up and affecting the operation of the conveyor belt. The problem.

In order to achieve the foregoing disclosure, the gas filling device comprises: a plurality of gas injection members, wherein the gas injection members are disposed on the support at intervals, each gas injection member comprises a body, a gas injection pipe and a gas pipe, The body is movably disposed on the bracket, the gas injection pipe is disposed on the body, the gas pipe is disposed on the body and communicates with the gas injection pipe; and a plurality of gas pipes are detachably assembled to the gas pipe In some of the gas injection parts, each of the gas injection tubes comprises a hollow tube body, one end of which is connected to the gas supply tube, and the tube body has a plurality of spaced-apart gas injection holes.

The gas filling device of the present invention allows the nitrogen gas and carbon dioxide injected into the gas injection tube to be dispersed and ejected from the gas injection holes by the gas injection holes, thereby reducing the pressure of the discharged gas flow and reducing the ejection speed, and the articles on the conveyor belt. It will not be blown by the nitrogen gas and carbon dioxide sprayed by the jet holes, and the operation of the conveyor belt can be maintained, and the function of filling the appropriate gas in the packaging bag can be achieved, and different numbers of the bets can be replaced according to the user's needs. The gas parts and the jet pipes can improve the convenience of switching and performing different packaging operations according to different packaging operations.

As shown in FIG. 1 to FIG. 3, a preferred embodiment of the gas filling device is disclosed. As can be seen from the drawings, the present gas filling device is disposed on a bracket 30 and includes a plurality of gas injection members 10 and a plurality of gas tubes. 20.

The gas injection members 10 are disposed on the bracket 30 at intervals. Each of the gas injection members 10 includes a body 11 , a gas injection pipe 12 and a gas pipe 13 . The body 11 is movably disposed on the frame 30 . The gas injection pipe 12 is disposed on the body 11 , and the gas supply pipe 13 is disposed on the body 11 and communicates with the gas injection pipe 12 , wherein each gas injection component 10 includes a buckle 14 and a support portion 15 , and the buckle 14 The end of the gas pipe 13 is connected to the gas pipe 20, and the support portion 15 is connected to the body 11 and the middle portion of the gas pipe 13.

The gas tubes 20 are detachably disposed on the gas injection members 10, each of the gas tubes 20 includes a hollow tube body 21, one end of the tube body 21 is connected to the gas tube 13, and the tube body 21 has a plurality of spaced-apart air blast holes 22, wherein the number of the gas vent holes 22 is 16 and two pairs are correspondingly located on opposite sides of the pipe body 21, and the two pairs of corresponding gas vent holes 22 are sandwiched by The angle of the inferior angle is 120 degrees.

As shown in FIG. 3 to FIG. 5, a preferred embodiment of the present gas filling device is disclosed. The user mounts the two gas injection members 10 on a conveyor belt (not shown) for packaging operation. 30, the distance between the two gas injection members 10 can be adjusted to conform to the articles to be conveyed on the conveyor belt (not shown), and the user buckles the two air injection pipes 20 with the two gas injection pipes. 10, the two jet tubes 20 can extend into the interior of a packaging bag 40 of the packaging operation, and a gas supply unit 41 delivers nitrogen gas and carbon dioxide into the two gas injection members 10, and then the nitrogen gas of the two gas injection members 10 is input. Carbon dioxide will follow the two gas injection pipes 12 and the two gas pipes 13 into the two gas injection pipes 20, and nitrogen and carbon dioxide flow in the two gas injection pipes 20 and are ejected from the end holes of the two gas injection holes 22 and the two gas injection pipes 20. The bag 40 is filled with gas smoothly, and the contents of the package 40 are combined with oxygen through nitrogen and carbon dioxide to achieve the purpose of preserving freshness.

In the above, when the two gas injection pipes 20 are venting nitrogen gas and carbon dioxide, since the gas injection holes 22 are spaced apart from each other on both sides of the two pipe bodies 21, the air flow discharged from the pipe ends of the two pipe bodies 21 can be dispersed. The pressure, and the velocity of the gas ejected from the end of the tube of the second tube 21 is lowered, so that the articles on the conveyor belt are not blown by the gas which is ejected from the nozzle holes 22 or the ends of the tubes 21, and the user also Depending on the environment in which the packaging operation is performed, two jet tubes 20 of different numbers of gas injection holes 22 may be installed on the two gas injection members 10, or the number of the gas injection members 10 and the plurality of the gas injection tubes 20 may be increased to accommodate different packaging. The need for work increases the convenience of switching to perform different packaging operations. In addition, the two supporting portions 15 increase the support of the two gas pipes 13, so that the two jet tubes 20 have better stability during jetting without swaying.

In summary, the gas filling device of the present invention allows the nitrogen gas and carbon dioxide injected into the two gas injection tubes 20 to be dispersed and ejected by the gas injection holes 22 by the gas injection holes 22, thereby reducing the pressure of the discharged gas flow. Moreover, the ejection speed is reduced, so that the articles on the conveyor belt are not blown by the nitrogen gas and the carbon dioxide emitted from the gas injection holes 22, and the operation of the conveyor belt is maintained, and the function of filling the packaging bag 40 with an appropriate gas can also be achieved. Moreover, the two supporting portions 15 can improve the stability of the two gas pipes 13 when the air is ejected, so that the two jet tubes 20 of different numbers of the gas injection holes 22 can be replaced according to the needs of the user, or the gas injection member 10 and the gas injection tube 20 can be added. The number can be matched with different packaging operations, which improves the convenience of switching between different packaging operations.
