A hot melt adhesive filling device 13 is installed in the filling station 11, and a nitrogen filling device 14 is installed in the nitrogen filling station 12. The nitrogen filling device 14 includes a fixed frame 15, a lifting box 16 installed in the fixed frame 15 via a bottom lifting assembly 17, a micro nitrogen generator 18 installed near the bottom of the fixed frame 15, a vacuum assembly 19 and a nitrogen filling assembly 20 installed on the side of the lifting box 16 via a side lifting assembly 21, a heat sealing assembly 22 installed on the side of the lifting box 16 and located below the vacuum assembly 19 and the nitrogen filling assembly 20, and the nitrogen filling assembly 20 connected to the micro nitrogen generator 18.

[0034] The working principle and beneficial effects of the above technical solution are as follows:

[0035] This utility model discloses an automatic filling and nitrogen-filling packaging device for PUR hot melt adhesive. After the PUR hot melt adhesive is filled at the filling station 11 by the hot melt adhesive filling equipment 13, the conveyor line 10 transports the filled PUR hot melt adhesive packaging bag to the nitrogen-filling station 12. The bottom lifting component 17 works, driving the lifting box 16 to move up and down to a certain height on the fixed frame 15. At this time, the heat sealing component 22 is exactly located at the bag opening of the PUR hot melt adhesive packaging bag. The side lifting component 21 works, thereby driving the vacuuming component 19 and the nitrogen-filling component 20 to extend into the PUR hot melt adhesive packaging bag. After the vacuuming component 19 evacuates the bag, the nitrogen-filling component 20 fills the PUR hot melt adhesive packaging bag with nitrogen. Then the side lifting component 21 works in the opposite direction, and the vacuuming component 19 and the nitrogen-filling component 20 quickly withdraw from the PUR hot melt adhesive packaging bag. The heat sealing component 22 works to complete the heat sealing of the bag opening of the PUR hot melt adhesive packaging bag. This utility model provides an automatic filling and nitrogen-filling packaging device for PUR hot melt adhesive. The vacuuming, nitrogen filling and sealing processes are completed at the nitrogen filling station 12, which improves efficiency.

[0036] In one embodiment, a vertical guide groove 28 is provided on the inner side wall of the fixed frame 15, a vertical guide rod 29 is installed in the vertical guide groove 28, a vertical guide block is slidably located in the vertical guide groove 28 and sleeved on the vertical guide rod 29, and the vertical guide block is installed on the side end of the lifting box 16.

[0037] The working principle of the above technical solution is as follows:

[0038] When the bottom lifting assembly 17 is working, it drives the lifting box 16 and the vertical guide block connected to the lifting box 16 to move up and down along the vertical guide rod 29 in the vertical guide groove 28.

[0039] In one embodiment, the bottom lifting assembly 17 includes:

[0040] Adjust the horizontal plate 23. Both ends of the horizontal plate 23 extend into the vertical guide groove 28 and are installed on the side of the fixed frame 15 by adjusting bolts 24.

[0041] Lifting screw block 25 is installed on adjusting horizontal plate 23;

[0042] The lifting motor 26 is installed at the bottom of the lifting box 16, the lifting screw 27 is installed at the output end of the lifting motor 26, and the lifting screw block 25 is sleeved on the lifting screw 27.

[0043] The working principle and beneficial effects of the above technical solution are as follows:

[0044] The lifting motor 26 located at the bottom of the lifting box 16 operates, thereby driving the lifting screw 27 installed at the output end of the lifting motor 26 to rotate. Since the adjusting plate 23 is fixedly installed in the fixing frame 15 by adjusting bolts 24, the lifting box 16 actively moves towards and away from the adjusting plate 23 with the cooperation of the lifting screw block 25 installed on the adjusting plate 23. In this way, the height of the heat sealing assembly 22 can be actively adjusted according to different specifications of PUR hot melt adhesive packaging bags.

[0045] In one embodiment, the side end of the fixing frame 15 has a plurality of adjustment holes that are evenly distributed from top to bottom and communicate with the vertical guide groove 28. The adjustment bolt 24 passes through the adjustment hole and is screwed onto the adjustment plate 23.

[0046] The beneficial effects of the above technical solution are as follows:

[0047] The adjusting bolt 24 allows for adjustment of the position of the adjusting plate 23 within the fixed frame 15, thereby changing the lifting height of the lifting box 16 to accommodate different specifications of PUR hot melt adhesive packaging bags.

[0048] Specifically, the higher the height of the adjustable horizontal plate 23, the lower the lifting height of the lifting box 16; conversely, the lower the height of the adjustable horizontal plate 23, the higher the lifting height of the lifting box 16.

[0049] In one embodiment, the side lifting assembly 21 includes:

[0050] The side sliding channel 30 is vertically opened at the side end of the lifting box 16, and the side slider 31 slides within the side sliding channel 30.

[0051] A side lifting motor 32 is installed inside the lifting box 16. A side lifting screw 33 is installed at the output end of the side lifting motor 32, and a side slider 31 is sleeved on the side lifting screw 33.

[0053] The working principle and beneficial effects of the above technical solution are as follows:

[0054] The side lifting motor 32 installed inside the lifting box 16 operates, thereby driving the side lifting screw 33 installed at the output end of the side lifting motor 32 to rotate. The side slider 31 sleeved on the side lifting screw 33 slides in the side sliding channel 30, thereby driving the side mounting plate 34 connected to the side slider 31, the vacuum assembly 19 and the nitrogen filling assembly 20 installed on the side mounting plate 34 to perform lifting movements, so that the vacuum assembly 19 and the nitrogen filling assembly 20 can extend into or be extracted from the PUR hot melt adhesive packaging bag.

[0055] In one embodiment, the vacuum assembly 19 includes:

[0056] The vacuum tube 35 is connected to the side mounting plate 34 via the mounting block 1. The bottom end of the vacuum tube 35 is flat and the top end of the vacuum tube 35 is equipped with a quick connector. One end of the hose 36 is connected to the quick connector at the top end of the vacuum tube 35, and the other end of the hose 36 extends into the lifting box 16 and is connected to the vacuum pump 37.

[0057] The working principle of the above technical solution is as follows:

[0058] Vacuum pump 37 operates, thereby driving vacuum tube 35 through hose 36. Vacuum tube 35 completes the vacuuming operation inside the PUR hot melt adhesive packaging bag. The bottom end of vacuum tube 35 is flat to minimize movement interference when heat sealing assembly 22 clamps the opening of PUR hot melt adhesive packaging bag.

[0059] In one embodiment, the nitrogen-filling assembly 20 includes:

[0060] Nitrogen filling pipe 38 is connected to side mounting plate 34 via mounting block 2. The bottom end of nitrogen filling pipe 38 is flat and the top end of nitrogen filling pipe 38 is equipped with quick connector.

The other end of hose 2 39 passes through lifting box 16 and is connected to the air outlet of filter 40. Filter 40 is installed on the side of fixed frame 15. Mini nitrogen generator 18 is connected to air inlet of filter 40 via hose 3.

[0061] The working principle and beneficial effects of the above technical solution are as follows:

[0062] The miniature nitrogen generator 18 operates, thereby facilitating the operation of the nitrogen filling tube 38 connected to the third hose, the second hose 39 connected to the third hose via the filter 40, and the nitrogen filling tube 38 connected to the second hose 39. The nitrogen filling tube 38 completes the nitrogen filling operation inside the PUR hot melt adhesive packaging bag. The bottom end of the nitrogen filling tube 38 is flattened to minimize movement interference when the heat sealing assembly 22 clamps the opening of the PUR hot melt adhesive packaging bag.

[0063] In one embodiment, a control panel 41 is installed on the side of the lifting box 16 near the top. The control panel 41 is located above the vacuum assembly 19 and the nitrogen filling assembly 20.
