[0028] like Figures 1-3 As shown, this embodiment provides a cigarette pack hot-sealing device, which includes a hot-sealing soldering iron and a guide block 1. The hot-sealing soldering iron includes a soldering iron body and a soldering iron core. The soldering iron body extends along a first direction. The guide block 1 is disposed at one end of the soldering iron body. A limiting surface 11 is provided on one side of the guide block 1 along a second direction. The limiting surface 11 is used to limit the cigarette pack. An installation groove 12 extending along the first direction is provided on the side of the guide block 1 near the soldering iron body. The soldering iron core is connected to the soldering iron body and extends into the installation groove 12. The soldering iron core is used to heat the soldering iron body and the guide block 1 so that the soldering iron body and the guide block 1 can hot-seal the transparent paper on the outside of the cigarette pack. When the clamping mechanism places the cigarette box onto the conveying device, the cigarette box is positioned corresponding to the guide blocks 1. The two guide blocks 1 are close to each other, and the two limiting surfaces 11 abut against the two sides of the cigarette box. The limiting surfaces 11 can restrict the position of the cigarette box, preventing it from tilting and affecting the hot-sealing effect, thus improving the hot-sealing quality. Furthermore, because the guide blocks 1 are heated by the soldering iron core, they can perform preliminary hot-sealing on the outer transparent paper of the cigarette box when they abut against the sides. Then, the two guide blocks 1 move away from the cigarette box, and the conveying device transports the cigarette box to the position corresponding to the soldering iron body. The two soldering iron bodies are close to each other and abut against the two sides of the cigarette box, further hot-sealing the outer transparent paper. During the process of transporting the cigarette box from the position corresponding to the guide blocks 1 to the position corresponding to the soldering iron body for hot-sealing, since the outer transparent paper of the cigarette box has already been preliminarily hot-sealed by the guide blocks 1, the outer transparent paper will not come undone, resulting in a better hot-sealing effect and further improving the hot-sealing quality. Moreover, this cigarette pack hot-sealing device has a simple structure and low cost.

[0029] Specifically, the first direction is the X direction, which is a direction within the horizontal plane. The second direction is the Y direction, which is a direction within the horizontal plane perpendicular to the first direction. The guide block 1 has a cubic structure. The limiting surface 11 is located on the side of the guide block 1 facing the cigarette box. The mounting groove 12 has a circular cross-section and is located in the middle of the guide block 1 along the vertical direction, which allows the guide block 1 to be heated more evenly.

[0030] Preferably, the guide block 1 is made of aluminum alloy, which has good thermal conductivity and low cost.

[0031] Preferably, such as Figure 2 As shown, the cigarette pack hot-sealing device also includes a set screw. A first threaded hole 13 is provided on the side wall of the mounting groove 12. The set screw is threaded into the first threaded hole 13 and abuts against the soldering iron core. Rotating the set screw tightens it against the soldering iron core, thus fixing it in place; rotating it in the opposite direction moves it away from the soldering iron core, allowing for installation and removal of the core. Specifically, the axis of the first threaded hole 13 and the axis of the mounting groove 12 are in the same plane and perpendicular to each other, ensuring a uniform radial locking force distribution of the set screw on the soldering iron core. The set screw is M3.

[0032] Preferably, such as Figure 1 As shown, a limiting member is provided on the side of the cigarette box facing the limiting surface 11, and the limiting surface 11 is provided with a relief groove 14 for avoiding the limiting member. Specifically, the relief groove 14 is elongated and is a through groove along the vertical direction.

[0033] Preferably, the guide block 1 is detachably connected to the soldering iron body, which facilitates the installation, disassembly and maintenance of the guide block 1.

[0034] More preferably, such as Figure 2 and Figure 3 As shown, the guide block 1 has a slotted hole 15, and the soldering iron body has a second threaded hole. A second screw passes through the slotted hole 15 and is threaded into the second threaded hole. By adjusting the position of the slotted hole 15 relative to the second threaded hole, the position of the guide block 1 can be adjusted. Depending on the specific situation, the guide block 1 can be adjusted to a suitable position, thereby improving the heat sealing effect of the guide block 1 on the cigarette box. Specifically, the slotted hole 15 extends along a second direction. The second screw is M5. During the adjustment of the guide block 1 position, the second screw is loosened, and the slotted hole 15 moves relative to the second threaded hole. When the slotted hole 15 moves to a suitable position, the second screw is tightened to firmly fix the guide block 1 against the soldering iron body.

[0035] Furthermore, there are two oblong holes 15, two second threaded holes, and two second screws, and each of the oblong holes 15, the second threaded hole, and the second screw corresponds to the other. The two oblong holes 15 are symmetrically arranged on both sides of the mounting groove 12. The two oblong holes 15 are spaced apart in the vertical direction. The guide block 1 is pressed and fixed to the soldering iron body by the two second screws, which improves the stability of the connection between the guide block 1 and the soldering iron body, and at the same time prevents the guide block 1 from rotating relative to the soldering iron body.

[0036] Preferably, the guide block 1 has a groove 16 on the side facing away from the soldering iron body, the waist-shaped hole 15 is located at the bottom of the groove 16, and the second screw is located inside the groove 16. The groove 16 can protect the second screw and prevent external objects from contacting the second screw and causing it to loosen. Specifically, the groove 16 has a U-shaped cross-section, and an opening is provided on one side wall of the groove 16 to facilitate the adjustment of the second screw.

[0037] Preferably, the cigarette pack hot-sealing device is provided with a protective cover, and the guide block 1 has a third threaded hole 17 for connecting with the protective cover on the side facing away from the soldering iron body. Specifically, there are two third threaded holes 17, which are spaced apart in the vertical direction and connected by the two third threaded holes 17 to improve the stability of the connection between the guide block 1 and the protective cover.

[0038] like Figures 1-3As shown, this embodiment also provides a cigarette packaging machine, which includes a stacking tower, a welding station, a conveying device, and the aforementioned cigarette pack hot sealing device. The conveying device is disposed between the stacking tower and the welding station. The conveying device is used to transport the cigarette box from the stacking tower to the welding station. Two cigarette pack hot sealing devices are respectively disposed on both sides of the conveying device. A guide block 1 is disposed at one end of the soldering iron body near the stacking tower. The two cigarette pack hot sealing devices can move closer to each other or further away. When the two cigarette pack hot sealing devices move closer to each other, the limiting surfaces 11 of the two soldering iron bodies and the two guide blocks 1 can respectively abut against the two sides of the cigarette box along the second direction. The soldering iron bodies and the guide blocks 1 hot seal the transparent paper on the outside of the cigarette box. When the two cigarette pack hot sealing devices move further away from each other, the soldering iron bodies and the limiting surfaces 11 move away from the cigarette box, and the cigarette box can be transported by the conveying device.

[0039] Specifically, the stacking tower is used to fold the transparent paper on the outside of the cigarette box. The welding station is used to shrink and shape the transparent paper on the outside of the cigarette pack. The clamping mechanism is used to clamp the cigarette box. The conveying device is used to transport the cigarette box from the stacking tower to the welding station. The cigarette pack hot-sealing device is mounted on the adjusting mechanism, which adjusts the position of the cigarette pack hot-sealing device along the second direction so that the two cigarette pack hot-sealing devices can move closer or further apart. The stacking tower, welding station, clamping mechanism, conveying device, and adjusting mechanism are all prior art and will not be described in detail here.
