Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 As shown, one embodiment of the present invention provides a packaging bag sealing device that can seal a packaging bag containing aromatherapy tablets. Of course, in other embodiments, other objects can be placed inside the packaging bag. The packaging bag is a plastic packaging bag with a storage space inside and an opening on one side. The packaging bag is sealed by heat pressing the opening.

[0040] like Figure 1 As shown, the packaging bag sealing device includes a workbench 100 , a lower sealing mold 200 , an upper sealing mold 300 and a positioning fixture 400 .

[0041] The workbench 100 is the main load-bearing and supporting structure, wherein the workbench 100 can be placed on other supports for use, or can be equipped with legs and placed on the ground for use.

[0042] The lower sealing mold 200 is disposed on the workbench 100 .

[0043] Specifically, the lower sealing mold 200 is disposed on the table surface of the workbench 100 .

[0044] In some embodiments, the lower sealing mold 200 is fixed on the table surface of the workbench 100. In other embodiments, the lower sealing mold 200 is configured as a detachable structure. In other embodiments, the lower sealing mold 200 can also be configured as a position-adjustable structure.

[0045] The upper sealing mold 300 is disposed on the workbench 100 and is located above the lower sealing mold 200 . The upper sealing mold 300 is disposed opposite to the lower sealing mold 200 , and the upper sealing mold 300 can be operatively moved closer to or away from the lower sealing mold 200 .

[0046] It is understood that the upper sealing mold 300 can be operated to move up and down. When the distance between the upper sealing mold 300 and the lower sealing mold 200 is large, it is convenient to place the side of the packaging bag with the opening between the upper sealing mold 300 and the lower sealing mold 200. After the upper sealing mold 300 is lowered and pressed against the lower sealing mold 200, the packaging bag can be sealed by heat pressing.

[0047] It should be noted that a heating wire can be installed inside the lower sealing mold 200. The heat generated by the heating wire can be transferred to the lower sealing mold 200 when the packaging bag is pressed between the upper sealing mold 300 and the lower sealing mold 200. The lower sealing mold 200 will press down and heat-seal the packaging bag to achieve a seal. In other embodiments, the heating wire can also be installed inside the upper sealing mold 300. In other embodiments, the heating wire can be installed inside both the upper sealing mold 300 and the lower sealing mold 200.

[0048] It can be understood that a bracket 500 is provided on the workbench 100, and a lifting drive member 600 is provided on the bracket 500. The upper sealing mold 300 is connected to the lifting drive member 600. The lifting drive member 600 is used to drive the upper sealing mold 300 to rise and fall, so that the upper sealing mold 300 is close to or away from the lower sealing mold 200.

[0049] The lifting drive member 600 may be manual or automatic.

[0050] In some embodiments, the lifting drive 600 is a screw-nut mechanism, and the upper sealing mold 300 is connected to the screw. By rotating the screw, the lower sealing mold 200 can be lifted and lowered; in other embodiments, the lifting drive 600 can be an electric screw, a cylinder or a hydraulic cylinder.

[0051] Furthermore, the upper sealing mold 300 is also connected to a guide rod 700 , the bracket 500 is provided with a guide hole, and the guide rod 700 is passed through the guide hole. This structure can guide the lifting and lowering of the upper sealing mold 300 .

[0052] Combine Figure 1 and Figure 3 The positioning fixture 400 is set on the workbench 100 to achieve positioning of the packaging bag.

[0053] Specifically, a positioning groove 410 is provided on the upper side of the positioning jig 400, and the packaging bag to be sealed can be placed in the positioning groove 410. When sealing the packaging bag, it is only necessary to place the packaging bag in the positioning groove 410, and then place the side of the packaging bag with the opening between the lower sealing mold 200 and the upper sealing mold 300. The operation is very convenient, and during the sealing process of the packaging bag, the operator does not need to hold the packaging bag by hand, which is conducive to improving the safety of the operation.

[0054] Furthermore, the positioning fixture 400 and the lower sealing mold 200 are arranged in parallel along the first horizontal direction, and the upper side of the positioning fixture 400 is provided with a plurality of positioning grooves 410, and the plurality of positioning grooves 410 are spaced and arranged in parallel along the second horizontal direction, wherein the first horizontal direction is perpendicular to the second horizontal direction.

[0055] It is understandable that the multiple positioning grooves 410 can simultaneously position multiple packaging bags. In other words, multiple packaging bags can be placed in the multiple positioning grooves 410 to achieve simultaneous sealing of the multiple packaging bags, which is conducive to improving work efficiency.

[0056] Specifically, the upper sealing mold 300 is an elongated structure, with its length oriented along the second horizontal direction. The lower sealing mold 200 is also an elongated structure, with its length oriented along the second horizontal direction. The positioning jig 400 is also an elongated structure, with its length oriented along the second horizontal direction. Furthermore, the positioning jig 400 and the lower sealing mold 200 are spaced apart along the first horizontal direction. A plurality of positioning grooves 410 are provided on the upper surface of the lower sealing mold 200, and the plurality of positioning grooves 410 are spaced apart along the second horizontal direction. After multiple packaging bags are placed into the plurality of positioning grooves 410, the upper sealing mold 300 and the lower sealing mold 200 can be used to simultaneously seal the multiple packaging bags.

[0057] Furthermore, the positioning groove 410 passes through a side of the positioning fixture 400 close to the lower sealing mold 200 .

[0058] It can be understood that a portion of the packaging bag to be sealed is used to be set in the positioning groove 410, while the portion with an opening extends out of the positioning groove 410 and is placed on the lower sealing mold 200. By making the positioning groove 410 pass through the side of the positioning jig 400 close to the lower sealing mold 200, compared with the solution in which the positioning groove 410 does not pass through the side of the positioning jig 400 close to the lower sealing mold 200, it can prevent the portion of the packaging bag close to its opening from being supported and tilted up.

[0059] Furthermore, the bottom wall of the positioning groove 410 is in the same plane as the upper surface of the upper sealing mold 300. In this way, when the packaging bag to be sealed is placed in the positioning groove 410, its open side can be placed relatively flat on the lower sealing mold 200, which is conducive to subsequent hot pressing operations.

[0060] Of course, in other embodiments, the height difference between the bottom wall of the positioning groove 410 and the upper surface of the upper sealing mold 300 can also be controlled within 5 mm.

[0061] Combine Figure 1 and Figure 2 In some embodiments, the positioning fixture 400 is adjustably disposed on the workbench 100 , and the positioning fixture 400 can be controlled to change the distance between the positioning fixture 400 and the lower sealing mold 200 in the first horizontal direction.

[0062] It is understandable that the lengths of different packaging bags may vary. By adjusting the distance between the positioning fixture 400 and the lower sealing mold 200 in the first horizontal direction, it can be ensured that after the packaging bag to be sealed is placed in the positioning groove 410, the side of the packaging bag with the opening is located directly above the lower sealing mold 200.

[0063] Combine Figure 1 and Figure 2 Specifically, the positioning jig 400 is provided with a first assembly hole 420 extending along the first horizontal direction and passing through the upper and lower sides of the positioning jig 400, and the workbench 100 is provided with a second assembly hole corresponding to the first assembly hole 420; the packaging bag sealing device also includes a fastener, which is removably provided through the first assembly hole 420 and the second assembly hole.

[0064] Specifically, the first assembly hole 420 is a strip-shaped hole, and the first assembly hole 420 extends along the first horizontal direction. Before adjusting the position of the positioning jig 400, the fastener needs to be pulled out. By moving the positioning jig 400 along the first horizontal direction while ensuring that the first assembly hole 420 and the second assembly hole are aligned, and then passing the fastener through the first assembly hole 420 and the second assembly hole, the position adjustment of the positioning jig 400 can be achieved.

[0065] Among them, the fastener is a screw, and the second assembly hole is a screw hole. By passing the screw through the first assembly hole 420 and the second assembly hole in sequence, and making the screw head of the screw abut against the positioning fixture 400, the positioning fixture 400 can be fixed.

[0066] Furthermore, a hidden hole 430 is provided on the upper surface of the positioning fixture 400. The hidden hole 430 is arranged around the upper end of the first assembly hole 420. The screw head of the screw can be placed in the hidden hole 430 to prevent the screw head from being exposed.

[0067] Combine Figure 4 and Figure 5 In some embodiments, the workbench 100 is provided with a recess 110 having a bottom wall and a positioning sidewall 111 connected to the bottom wall and extending in a first horizontal direction. The packaging bag sealing device further includes a positioning member 450 having a positioning surface 451. The positioning member 450 is connected to the positioning jig 400 so that the positioning surface 451 is aligned with and positioned in alignment with the positioning sidewall 111. When adjusting the position of the positioning jig 400, the positioning surface 451 is aligned with the positioning sidewall 111 to ensure parallelism between the positioning jig 400 and the lower sealing mold 200.

[0068] It is understood that when adjusting the position of the positioning jig 400, by abutting the positioning surface 451 against the positioning sidewall 111, the positioning jig 400 can be accurately moved along the first horizontal direction and prevented from tilting. In this way, the parallelism between the positioning jig 400 and the lower sealing mold 200 can be ensured. In this way, after multiple packaging bags to be sealed are placed into the multiple positioning grooves 410, the risk of some packaging bags to be sealed having their openings accurately positioned directly above the lower sealing mold 200 while other packaging bags having their openings not positioned directly above the lower sealing mold 200 due to the tilt of the positioning jig 400 can be reduced.

[0069] Specifically, the positioning fixture 400 is provided with a mounting portion 440, the mounting portion 440 is provided with a mounting hole 441, the mounting hole 441 is arranged opposite to the positioning side wall 111, and the mounting hole 441 and the positioning side wall 111 are arranged along the second horizontal direction, the positioning member 450 is passed through the mounting hole 441 and the positioning surface 451 is arranged toward the positioning side wall 111.

[0070] Furthermore, the positioning member 450 has a threaded section, the mounting hole 441 is a screw hole, the threaded section is passed through the screw hole, and the positioning member 450 can be operably rotated to approach or move away from the positioning side wall 111.

[0071] It can be understood that by rotating the positioning member 450, the positioning surface 451 can be moved along the second horizontal direction. In this way, manufacturing or assembly errors can be eliminated, ensuring that the positioning surface 451 and the positioning side wall 111 can also fit together under the premise that the first assembly hole 420 and the second assembly hole are aligned.

[0072] The mounting portion 440 is connected to the lower side wall of the positioning fixture 400 and is located in the groove 110 .

[0073] Combine Figure 6 and Figure 7In some embodiments, a hand guard 460 is connected to the side of the positioning jig 400 close to the lower sealing mold 200. The hand guard 460 can prevent the positioning jig 400 from directly contacting the lower sealing mold 200. In this way, the lower sealing mold 200 can be prevented from being heated and the temperature can be increased, reducing the risk of scalding the operator's hands.

[0074] In addition, when the operator adjusts the position of the positioning fixture 400 , the risk of the operator being burned due to the fingers touching the lower sealing mold 200 due to operating errors can be reduced.

[0075] Furthermore, the hand guard 460 defines a hand-grip groove. When the operator adjusts the position of the positioning fixture 400, the operator can insert the index finger into the hand-grip groove and hold the positioning fixture 400. The hand guard 460 can prevent the operator's index finger from being burned by the lower sealing mold 200.

[0076] When the packaging bag sealing device of the present invention is in use, the packaging bag to be sealed can be placed in the positioning groove 410. When sealing the packaging bag, it is only necessary to place the packaging bag in the positioning groove 410, and then place the side of the packaging bag with the opening between the lower sealing mold 200 and the upper sealing mold 300, and then operate the upper sealing mold 300 to descend, so that the packaging bag is heat-pressed and sealed. The operation is very convenient, and during the sealing process of the packaging bag, the operator does not need to hold the packaging bag with his hands, which is conducive to improving the safety of the operation.
