Description

Technical Field

[0001] The invention relates to the technical field of amino acid injection processing, in particular to a nitrogen filling and plugging device for amino acid injection. Background Art

[0002] Amino acid injection is a nutritional supplement drug used for patients with insufficient protein intake, malabsorption, and other conditions where amino acids cannot meet the body's metabolic needs. It can also be used to improve the nutritional status of patients after surgery. During the production process, amino acid injection is poured into glass bottles. In order to ensure its shelf life, it needs to be nitrogen-filled and plugged.

[0003] For example, the patent with publication number CN212829294U discloses a nitrogen filling and plugging device for amino acid injection, comprising an operating table, a limiting groove is drilled on the operating table, a cylinder is fixedly installed at the bottom of the limiting groove, a material box is fixedly installed at the output end of the cylinder, a bottle body is clamped and placed in the material box, a sealing plug is clamped in the bottle mouth of the bottle body, an air guide tube is inserted into and fixedly installed on the sealing plug, a plastic bag is provided on the air guide tube, two slide rails are symmetrically fixedly installed on the top of the operating table, a slide is slidably installed on the two slide rails, a sealing mechanism is fixedly installed on the top of the slide, a support frame is fixedly installed on the top of the operating table and away from the slide, and an air pump is fixedly installed on the top of the support frame.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides a technical solution: a nitrogen filling and plugging device for amino acid injection, comprising a workbench 1, a mounting frame 4 is fixed on the upper side of the workbench 1, a placement box 11 is slidably fitted in the workbench 1, an amino acid injection bottle 10 is installed in the placement box 11, a rubber stopper 16 is installed at the bottle mouth of the amino acid injection bottle 10, a nitrogen filling tube 15 is fixed on the lower side of the mounting frame 4, a pressing plate 31 is installed on the lower side of the mounting frame 4, the pressing plate 31 and the nitrogen filling tube 15 correspond to the rubber stopper 16, a rubber plate 20 is installed at the bottom of the rubber stopper 16, a first electric cylinder 2 is fixed on the mounting frame 4, a suction cup 28 is fixed to the output end of the first electric cylinder 2, and a sealing cover 17 is adsorbed on the lower side of the suction cup 28.

[0029] In this embodiment, a second electric cylinder 3 is fixed in the workbench 1, and the output end of the second electric cylinder 3 is fixedly connected to the placement box 11. A plurality of clamping blocks 14 are installed in the placement box 11. The amino acid injection bottle 10 is located between the plurality of clamping blocks 14. A first spring 12 is fixed between the clamping blocks 14 and the placement box 11.

[0030] Specifically, when the amino acid injection bottle 10 needs to be filled with nitrogen and plugged, the amino acid injection bottle 10 is placed in the placement box 11. At this time, the first spring 12 pushes the clamping block 14 to clamp and fix the amino acid injection bottle 10, thereby ensuring the stability of the amino acid injection bottle 10 during nitrogen filling and plugging, and at the same time making the device applicable to various types of amino acid injection bottles 10. Then, the second electric cylinder 3 is started to push the amino acid injection bottle 10 upward, and nitrogen filling and plugging can be performed.

[0031] A groove is provided in the workbench 1, and a limit ring 6 is fixed on the mounting frame 4. The limit ring 6 and the groove correspond to the nitrogen cylinder 5. An air pump 7 is fixed on the mounting frame 4. A first hose 8 is fixed between the air inlet of the air pump 7 and the nitrogen cylinder 5, and a second hose 9 is fixed between the air outlet of the air pump 7 and the nitrogen filling pipe 15.

[0032] Specifically, when the nitrogen cylinder 5 needs to be replaced, the old nitrogen cylinder 5 is taken out from the groove, and then the new nitrogen cylinder 5 is inserted into the groove through the limiting ring 6, so that the limiting ring 6 and the groove limit and fix the nitrogen cylinder 5, thereby realizing the replacement of the nitrogen cylinder 5.

[0033] When nitrogen filling is required, the air pump 7 is started to draw nitrogen from the nitrogen bottle 5 through the first hose 8, and then the nitrogen in the nitrogen bottle 5 is sent into the nitrogen filling pipe 15 through the second hose 9, thereby achieving nitrogen filling.

[0034] The pressing plate 31 is slidably connected to the nitrogen filling pipe 15 , and a plurality of telescopic rods 22 are fixed between the pressing plate 31 and the mounting frame 4 .

[0035] Specifically, before nitrogen filling, the amino acid injection bottle 10 is placed in the placement box 11, and then the placement box 11 is pushed upward, thereby pushing the amino acid injection bottle 10 upward, so that the pressure plate 31 contacts the rubber stopper 16, and the pressure plate 31 presses the rubber stopper 16 relatively downward until the rubber stopper 16 is pressed into the amino acid injection bottle 10. At this time, the telescopic rod 22 is compressed, and the nitrogen filling tube 15 is inserted into the rubber stopper 16 for nitrogen filling. When the nitrogen filling tube 15 is pulled out upward, the pressure plate 31 presses the rubber stopper 16 so that the rubber stopper 16 is always located in the amino acid injection bottle 10, thereby preventing the rubber stopper 16 from falling off, and the nitrogen filling tube 15 can be pulled out at the same time.

[0036] The telescopic rod 22 includes a first rod body 23 and a second rod body 24. The first rod body 23 is a hollow structure, and the first rod body 23 and the second rod body 24 are slidably connected. A second spring 13 is fixed between the top of the first rod body 23 and the second rod body 24. A slide groove 25 is provided on one side of the first rod body 23, and a plurality of positioning grooves 27 are provided in the slide groove 25. A slide rod 26 is slidably fitted in the slide groove 25, and a positioning block is fixed on the side of the slide rod 26, and the positioning block corresponds to the positioning groove 27. An insertion port 18 and a plurality of air outlets 19 are provided in the rubber stopper 16, and a plurality of through grooves are provided in the pressure plate 31. The through grooves are the same size as the air outlet 19, and the insertion port 18 corresponds to the nitrogen filling tube 15.

[0037] Specifically, the sliding rod 26 is slid so that the sliding rod 26 slides in the sliding groove 25. The sliding rod 26 is fixed in a certain position by the positioning groove 27 and the positioning block. When the nitrogen filling tube 15 is inserted into the insertion port 18, the telescopic rod 22 is compressed, thereby causing the second rod body 24 to slide until the second rod body 24 is limited by the sliding rod 26, thereby fixing the length of the nitrogen filling tube 15 inserted into the amino acid injection bottle 10. Then, when the nitrogen filling tube 15 is pulled out upward, under the action of the second spring 13, the telescopic rod 22 is stretched, so that the pressure plate 31 is always in contact with the rubber stopper 16, thereby preventing the rubber stopper 16 from falling off.

[0038] The rubber stopper 16 is in contact with the rubber plate 20 . A connecting block 21 is fixed between the rubber stopper 16 and the rubber plate 20 . The connecting block 21 is made of rubber material.

[0039] Specifically, when the nitrogen filling tube 15 is inserted into the rubber plug 16, the nitrogen filling tube 15 will push the rubber plate 20 downward, so that a gap is formed between the rubber plate 20 and the rubber plug 16, thereby facilitating the entry of nitrogen and air. When the nitrogen filling tube 15 is pulled out, the rubber plate 20 is quickly reset under the elastic action of the connecting block 21 and the rubber plate 20 itself, thereby preventing air leakage.

[0040] A rubber block 30 is fixed to the middle of the sealing cover 17 , and a sealing rod 29 is fixed inside the sealing cover 17 , and the sealing rod 29 corresponds to the air outlet 19 .

[0041] Specifically, after the nitrogen filling and plugging are completed, the amino acid injection bottle 10 is placed under the sealing cover 17, and then the first electric cylinder 2 is started, so that the first electric cylinder 2 pushes the sealing cover 17 downward, so that the sealing cover 17 is stuck at the bottle mouth of the amino acid injection bottle 10, so that the sealing rod 29 is inserted into the air outlet 19 to ensure the sealing of the amino acid injection bottle 10.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
