[0032] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] In order to realize the automatic sealing of the packaging bag with the electronic cigarette rod, refer to Figures 1 to 4 The embodiment includes: a transport plane 1, a support plate 2 and two heat-sealing press plates 5 are provided, a plurality of feeding fixtures 11 are evenly distributed on the top of the transport plane 1, and strip grooves 12 are provided inside the feeding fixtures 11, and the strip grooves 12 are used to place packaging bags with electronic cigarette rods, so that the transport plane 1 can transport packaging bags with electronic cigarette rods, the support plate 2 is provided outside the transport plane 1, and a connecting plate 20 is provided on the top of the support plate 2. 2 and the connecting plate 20 are both provided with a clamping cylinder 4 on the outside, and the two heat-sealing pressure plates 5 are connected to the power output ends of the two clamping cylinders 4 one by one, and the transport plane 1 is also located between the two heat-sealing pressure plates 5, so that the two heat-sealing pressure plates 5 can be driven by the two clamping cylinders 4 to align with the bag opening position, and the two heat-sealing pressure plates 5 move synchronously and clamp and seal the packaging bag on the transport plane 1 to complete the heat-sealing action, effectively realizing the automatic sealing action of the packaging bag with the electronic cigarette rod, thereby improving the work efficiency.

[0035] It should be noted that in order to push the packaging bag with the electronic cigarette rod on the transport plane 1 close to the heat sealing plate 5, as Figure 1 to Figure 2 As shown, in this embodiment, an ejection mechanism 7 is further provided on the outside of the transport plane 1, and the ejection mechanism 7 is moved close to the outside of the transport plane 1 so that the ejection mechanism 7 corresponds to the pressing mechanism 3. The ejection mechanism 7 includes a first pushing cylinder 71 and a first pushing plate 72. The first pushing plate 72 is fixed to the power output end of the first pushing cylinder 71, and one side of the first pushing plate 72 is facing the other end of the strip groove 12. Then, the first pushing plate 72 can be driven by the first pushing cylinder 71, and the packaging bag inside the strip groove 12 is pushed by the first pushing plate 72. The packaging bag with the electronic cigarette rod moves along one end of the strip groove 12 to the other end of the strip groove 12, and moves close to between the two heat sealing press plates 5.

[0036] It should be noted that since the surface of the packaging bag is relatively smooth, in order to achieve heat sealing of the bag by clamping the bag opening of the packaging bag between the two heat sealing platens 5, anti-slip grooves are provided on one side of the two heat sealing platens 5 close to the transport plane 1 to increase the anti-slip property, and heating elements are provided inside the heat sealing platens 5 to supply heat to the heat sealing platens 5.

[0037] It should also be noted that, in order to ensure that when the packaging bag of the electronic cigarette rod is pushed close to the heat-sealing press plate 5, the electronic cigarette rod will not be pushed out of the packaging bag, in this embodiment: a pressing mechanism 3 is also provided, so that the connecting plate 20 is located directly above the transport plane 1, and the pressing mechanism 3 is arranged outside the connecting plate 20, and the pressing mechanism 3 is close to one end of the strip groove 12, thereby realizing the transportation of the packaging bag with the electronic cigarette rod to the pressing mechanism 3, and the packaging bag in the strip groove 12 is pressed by the pressing mechanism 3, wherein the pressing mechanism 3 includes a lifting cylinder 31 and at least one pressing plate 32, and the pressing plate 32 is arranged at At the power output end of the lifting cylinder 31, the bottom of the pressing plate 32 is aligned with the transport plane 1, and the pressing plate 32 is driven to rise or fall by the lifting cylinder 31. When the strip groove 12 is directly below the pressing plate 32, the pressing plate 32 can be driven to fall by the lifting cylinder 31 to press the packaging bag, which effectively ensures that there will be no position deviation during the sealing process of the packaging bag, and ensures that the sealing position is accurate. By opening a pressing opening 321 at the bottom center of the pressing plate 32, the pressing opening 321 is adapted to the electronic cigarette rod, thereby ensuring that the electronic cigarette rod will not be crushed during the pressing process of the packaging bag.

[0038] It should be noted that in order to prevent the electronic cigarette rod inside the packaging bag from tilting or shifting during the pressing process, two pressing plates 32 can be used to press and limit the two ends of the electronic cigarette rod in the strip groove 12 to prevent the electronic cigarette rod from tilting and shifting. In this embodiment, two pressing plates 32 are provided, and the two pressing plates 32 are symmetrically positioned. The two pressing plates 32 are also arranged on the power output end of the lifting cylinder 31. The lifting cylinder 31 is used to synchronously control the lifting distance of the two pressing plates 32, so that one of the pressing plates 32 is close to one end of the strip groove 12, and the other pressing plate 32 is close to the other end of the strip groove 12, thereby achieving that during the pressing process of the two pressing plates 32, one pressing plate 32 presses one end of the electronic cigarette rod, and the other pressing plate 32 presses the other end of the electronic cigarette rod, thereby ensuring the stability of the electronic cigarette rod.

[0039] In view of the above, it is necessary to add that if Figure 4 As shown, the pressing opening 321 is set in an inverted "V" shape as a whole, so as to ensure that the pressing opening 321 can correct the electronic cigarette rod during the pressing process. When the pressing opening 321 is completely pressed against the electronic cigarette rod, that is, when the electronic cigarette rod is close to the top of the pressing opening 321, the electronic cigarette rod can be limited and fixed.

[0040] Embodiment 2

[0041] In order to flatten the bag mouth during the heat sealing process, so as to facilitate the subsequent heat-pressing and sealing of the bag mouth, and prevent the bag mouth from warping outwards and causing inaccurate heat-pressing and sealing positions, refer to Figures 1 to 3 As shown, in this embodiment, a flattening mechanism 6 is included, and the flattening mechanism 6 includes a movable plate 61 and a right-angle bent plate 62. The right-angle bent plate 62 is arranged on the top of the movable plate 61, and one side of the right-angle bent plate 62 is also in contact with the transport plane 1, so that the bottom of the movable plate 61 is slidably arranged on the supporting plate 2. By arranging an ejection cylinder 21 on the top of the supporting plate 2, the power output end of the ejection cylinder 21 is connected to the other end of the movable plate 61, and the ejection cylinder 21 can be used to control the moving distance of the movable plate 61. When the movable plate 61 moves toward the transport plane 1, the right-angle bent plate 62 approaches the transport flat plate. Since one side of the right-angle bent plate 62 is in contact with the transport plane 1, the packaging bag on the transport plane 1 can be pre-pressed and flattened by the right-angle bent plate 62 to ensure that the bag mouth of the packaging bag is straight, to prevent the bag mouth from being uneven and warping during subsequent heat sealing, which affects the hot pressure sealing, and can effectively ensure that the bag mouth of the packaging bag is flattened.

[0042] In order to prevent the situation that the electronic cigarette rod is pushed out when the heat-sealed bag opening is pushed close to the heat-sealed pressing plate 5, once the electronic cigarette rod is close to the packaging bag opening, the electronic cigarette rod will be crushed when the heat-sealed bag opening is pressed. Therefore, in view of the above description, it is necessary to further supplement that, with reference to Figures 1 to 3 When the right-angle bend plate 62 approaches the transport plane 1, it can push the electronic cigarette rod near the bag opening, thereby preventing the end of the electronic cigarette rod from being too close to the bag opening of the packaging bag, and effectively preventing the electronic cigarette rod from being crushed during the hot pressing and sealing process. Embodiment three is to realize the automatic pushing of the packaging bag with the electronic cigarette rod close to the heat sealing plate 5. After the heat sealing plate 5 performs hot pressing and sealing on the bag opening, the sealed packaging bag is pushed back to the center of the strip groove 12 again to prevent the transportation of blanking materials from being scratched and broken due to the bag opening leaking out of the transport plane 1. In this embodiment: a plurality of feeding clamps 11 are evenly distributed on the top of the transport plane 1, and strip grooves 12 are arranged inside the feeding clamps 11. The strip grooves 12 are all used to place the packaging bag with the electronic cigarette rod, so that the transport plane 1 can transport the packaging bag with the electronic cigarette rod. A pushing mechanism 8 is provided at the end, and the pushing mechanism 8 is arranged near the outside of the supporting plate 2. The pushing mechanism 8 includes a second pushing cylinder 81 and a second pushing plate 82. The power output end of the second pushing cylinder 81 is connected to the second pushing plate 82. One side of the second pushing plate 82 faces one end of the strip groove 12, and then the second pushing cylinder 81 can drive the second pushing plate 82 to move toward one end of the strip groove 12, and push the sealed packaging bag from one end of the strip groove 12 to the center of the strip groove 12, which can effectively return the sealed packaging bag to its original position and prevent the bag opening from being scratched and damaged due to being close to the outside of the transport plane 1.

[0043] With respect to the technical solutions of the above embodiments, it is particularly noted that in order to achieve uniform upper and lower forces during the hot pressing and sealing process, and to insulate the product inside the packaging bag to prevent the temperature from damaging the components inside the packaging bag, as shown in FIG. Figure 3 As shown, by arranging the two heat-sealing platens 5 symmetrically, heat-insulating vertical plates 51 are provided on the outside of the two heat-sealing platens 5, and a movable plate 52 is connected to one end of the heat-insulating vertical plate 51, so that the movable plate 52 is hinged on the supporting plate 2. Then, heat-insulating vertical plates 51 are provided on the outside of the two heat-sealing platens 5, and the heat-insulating vertical plates 51 can further ensure that the bag opening of the packaging bag fits well, preventing the bag opening from warping outward and achieving a heat-insulating effect.
