[0033] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0034] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The technical personnel of the present application have found that after the transparent paper side sealing iron is used to heat seal the cigarette box, there are quality problems such as uneven overlap and wrinkles, which are related to the low temperature of the two ends of the side sealing iron. Since the length of the transparent paper side sealing iron of the current cigarette box is consistent with the length of the cigarette box, and the length of the heating tube cannot fully cover the iron, the heat dissipation area on both sides of the side sealing iron is large, which leads to the low temperature on both sides of the transparent paper side sealing iron, which affects the heat sealing quality and has problems such as uneven overlap and wrinkles. The embodiment of the present application provides a cigarette box transparent paper side sealing mechanism to solve the above technical problems.

[0037] Specifically, refer to Figures 1 to 4 The transparent paper side sealing mechanism of the cigarette box of the embodiment of the present application comprises a forming wheel 10 and a side sealing iron mechanism 20. The forming wheel 10 is provided with a plurality of receiving grooves 13 at intervals along its circumference, and the receiving grooves 13 are used to receive the cigarette box 40, and the cigarette box 40 can rotate with the forming wheel 10 to the heat sealing station (such as Figure 1 and Figure 5 S in the middle) along the first direction (as shown Figure 1and Figure 4 The two side end surfaces of the cigarette box 40 are in contact with the inner side wall of the receiving groove 13, and the surface to be heat-sealed of the cigarette box 40 is along the second direction (as shown in FIG. Figure 4 The side sealing iron mechanism 20 includes an iron 21, which is arranged on one side of the forming wheel 10. The iron 21 can move along the second direction to contact or separate from the surface to be heat-sealed of the cigarette box 40 ( Figures 1 to 4 The state where the soldering iron 21 is in contact with the surface to be heat-sealed is shown in the figure). The first direction is the axial direction of the forming wheel 10, and the second direction is the radial direction of the forming wheel 10. Along the first direction, the soldering iron 21 includes a body 210, and the body 210 has a first end face 211 and a second end face 212 spaced apart along the first direction. The lower end face of the body 210 is provided with a heating surface, and the heating surface is used to contact the surface to be heat-sealed of the cigarette box to perform heat sealing. The first end face 211 is flush with the inner side wall of the material receiving groove 13 at the corresponding end thereof, and the second end face 212 is flush with the inner side wall of the material receiving groove 13 at the corresponding end thereof. That is to say, the soldering iron 21 is in contact with the surface to be heat-sealed of the cigarette box 40 and can just completely cover the surface to be heat-sealed of the cigarette box 40 for heat sealing.

[0038] Reference Figure 1 and Figure 4 In a specific embodiment, the side walls of the material receiving groove 13 are respectively connected to the first cigarette box side plate 11 and the second cigarette box side plate 12 on the forming wheel 10, and the material receiving groove 13 and the first cigarette box side plate 11 and the second cigarette box side plate 12 are enclosed to form a cavity for accommodating the cigarette box 40. Along the first direction, the cigarette box 40 includes a first side surface 41 and a second side surface 42, the inner side wall 111 of the first cigarette box side plate contacts the first side surface 41, and the inner side wall 121 of the second cigarette box side plate contacts the second side surface 42.

[0039] Further, along the first direction, a first extension portion 213 is protrudingly provided on the first end surface 211, and / or a second extension portion 214 is protrudingly provided on the second end surface 212. It can be understood that the first extension portion 213 is formed by a portion of the first end surface 211 protruding along the first direction, and / or the second extension portion 214 is formed by a portion of the second end surface 212 protruding along the first direction. Figure 4 As shown, in the first direction, the end surface of the first extension portion 213 exceeds the inner side wall 111 of the first cigarette box side plate, and / or the end surface of the second extension portion 214 exceeds the inner side wall 121 of the second cigarette box side plate.

[0040] That is to say, the end face portion of at least one end of the main body 210 is extended beyond the side end face of the corresponding end cigarette box 40 to reduce the temperature loss of the end face, reduce the heat loss between the heating surface and the part close to the end, and make the temperature of the entire heating surface more balanced when in contact with the surface to be heat-sealed of the cigarette box 40, thereby improving the heat sealing quality.

[0041] Furthermore, along the second direction (such as Figure 4 As shown in the H direction, there is a gap between the first extension portion 213 and the second extension portion 214 and the receiving groove 13. Figure 4 In the second direction, the first extension part 213 and the first cigarette box side plate 11 have a first interval 215, so that the first extension part 213 does not contact the end surface of the first cigarette box side plate 11, so as to give way to the first cigarette box side plate 11 and avoid interference. The second extension part 214 and the second cigarette box side plate 12 have a second interval 216, so that the second extension part 214 does not contact the end surface of the second cigarette box side plate 12, so as to give way to the second cigarette box side plate 12 and avoid interference.

[0042] That is, in the first direction, the first extension portion 213 and the second extension portion 214 both extend in a direction away from the center of the soldering iron 21, thereby lengthening the overall length of the soldering iron 21, reducing the temperature loss of the first end face 211 and the second end face 212 of the body 210, thereby reducing the heat loss of the heating surface near the first end face 211 and the second end face 212, thereby making the temperature of the heating surface more balanced when in contact with the surface to be heat-sealed of the cigarette box 40, thereby improving the flatness and aesthetics of the side sealing overlap of the cigarette box transparent paper, and improving the heat-sealing quality of the cigarette box transparent paper. In addition, the first end face 211 and the first extension portion 213 are stepped, and the second end face 212 and the second extension portion 214 are stepped. The soldering iron 21 adopts a stepped end face to avoid interference with the cigarette box side panels at both ends during the heat sealing process, thereby improving practicality.

[0043] In a specific embodiment, the extension length of the first extension portion 213 is greater than the thickness of the first cigarette box side plate 11, and / or the extension length of the second extension portion 214 is greater than the thickness of the second cigarette box side plate 12. That is, in the first direction, the first extension portion 213 extends outwardly beyond the outer end surface of the first cigarette box side plate 11, and the second extension portion 214 extends outwardly beyond the outer end surface of the second cigarette box side plate 12.

[0044] In one embodiment, the extension length of the first extension portion 213 is the same as the extension length of the second extension portion 214. In another embodiment, the extension length of the first extension portion 213 is different from the extension length of the second extension portion 214.

[0045] Further, refer to Figures 1 to 4, further comprising a heating tube 22, the heating tube 22 being at least partially located in the soldering iron 21 and extending along the first direction, the terminal end surface 222 of the heating tube 22 exceeding the first side surface 41 or the second side surface 42 of the cigarette box 40 and being located in the first extension portion 213 or the second extension portion 214. In a specific embodiment, the terminal end surface 222 of the heating tube 22 extends to the end surface of the first extension portion 213 or the second extension portion 214. The increase in the length of the heating tube 22 located in the soldering iron 21 can further increase the temperature of the end surfaces on both sides of the soldering iron 21, thereby solving the problem of low temperature caused by the large heat dissipation area of ​​the end surfaces on both sides of the side-sealed soldering iron 21, and then causing the problem of sealing quality.

[0046] Continue to refer to Figure 1 and Figure 4 In a specific embodiment, the connection port 221 through which the heating tube 22 passes through the soldering iron 21 is close to the second end face 212, and the heat of the heating tube 22 is transferred from the second end face 212 to the first end face 211. In this embodiment, the extension length of the second extension portion 214 is greater than the extension length of the first extension portion 213, that is, the extension length of the extension portion close to the connection port 221 through which the heating tube 22 passes through the soldering iron 21 is greater. Since the soldering iron 21 has a poor wrapping property for the heating tube 22 at the connection port 221 and is easy to dissipate heat, the extension portion close to the connection port 221 extends a longer distance to reduce the temperature loss of the soldering iron 21 at this end. Exemplarily, the extension length of the first extension portion 213 is 5 mm, and the extension length of the second extension portion 214 is 10 mm.

[0047] Reference Figure 5 , an arc plate 30 is also arranged outside the forming wheel 10, the arc plate 30 surrounds at least a part of the forming wheel 10 in the circumferential direction, a clearance slot 31 is arranged on the arc plate 30, and the soldering iron 21 is arranged on the outer side of the arc plate 30, and the soldering iron 21 can move along the second direction to penetrate the clearance slot 31 and contact or separate with the surface to be heat-sealed of the cigarette box 40; along the first direction, there is a gap between the end faces of the first extension part 213 and the second extension part 214 and the inner side wall of the clearance slot. In other words, the extension length of the first extension part 213 and the second extension part 214 cannot exceed the inner groove wall of the first groove hole, so as to prevent the soldering iron 21 from interfering with the clearance slot 31 during operation.

[0048] In summary, in this embodiment, the body of the soldering iron 21 is lengthened by the first extension part 213 and the second extension part 213, and the two end faces of the soldering iron 21 are stepped, so as to make way for the first cigarette box side plate 11 and the second cigarette box side plate 12 at both ends of the butt material slot 13. And by extending the length of the heating tube 22 in the soldering iron 21, the heat loss of the end face of the soldering iron 21 is further reduced, so that the temperature of the soldering iron 21 is more balanced when it contacts the surface to be heat-sealed of the cigarette box 40, and the flatness and aesthetics of the side seal of the transparent paper of the cigarette box are improved, and the heat-sealing quality is improved.

[0049] Another embodiment of the present application discloses a transparent paper packaging machine, referring to Figure 1 and Figure 5 , including a forming wheel 10 and the above-mentioned cigarette box transparent paper side sealing mechanism, the side sealing soldering iron mechanism 20 also includes a transmission shaft 24 for driving the soldering iron 21 to move, the soldering iron 21 is connected to the bracket 23 through a fixing member 25, and the transmission shaft 24 drives the soldering iron 21 to move along the second direction through the bracket 23. During operation, when the forming wheel 10 drives the cigarette box 40 to rotate, the soldering iron 21 moves away from the forming wheel 10 along the second direction to avoid interference; when the cigarette box 40 rotates to the heat sealing station, the soldering iron 21 moves along the second direction to contact the surface to be heat-sealed of the cigarette box 40, seals and heats it, and completes the heat sealing of the transparent paper side sealing overlap of the cigarette box 40.
