[0002] A layer of transparent paper is wrapped outside the packing box, which can make the packing box beautiful, sealed and moisture-proof, and is a common packaging method for various products, including cigarettes. The transparent paper needs to be hot sealed on the packing box, including completing the hot sealing of the side long edge of the packing box through the packing box transparent paper side long edge hot sealing device and completing the hot sealing of both ends of the packing box through the packing box transparent paper end hot sealing device.

[0003] In production, the transparent paper hot sealing often causes the maximum surface 102 of the packing box to have curtain-shaped wrinkles, affecting the appearance and sealing effect. Through analysis of the manifestation of such wrinkles and the forming and hot sealing process of the transparent paper, it is found that the wrinkles occur at the two end surfaces, specifically caused by inconsistent shrinkage of the transparent BOPP film after hot sealing of the two end surfaces.

The problem is that if the area of the notch at the edge of the iron is too large, the hot sealing is insufficient, and the packaging air tightness is poor; if the area of the notch at the edge of the iron is too small, the maximum surface 102 will still have curtain-shaped wrinkles.

[0005] Therefore, it is a technical problem to be solved in the field to provide an end transparent paper hot sealing device that can reduce the occurrence of curtain-shaped wrinkles on the maximum surface of the packing box and make the packing box have better air tightness.

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by one of ordinary skill in the art without paying creative labor belong to the scope of protection of the present application.

[0031] Please refer to Figures 1-2Some embodiments of the present application provide an end transparent paper heat sealing iron for heat sealing the transparent paper of the smallest end face of a package box, comprising a first working surface 1 and a second working surface 2 which contact and heat seal the transparent paper in turn, the first working surface 1 and the second working surface 2 comprising: a repeated heat sealing part 31 corresponding to the same area of the transparent paper in the first working surface 1 and the second working surface 2, and a single heat sealing part 32 corresponding to different areas of the transparent paper in the first working surface 1 and the second working surface 2.

[0032] The curtain-shaped wrinkles of the largest face 102 of the package box are caused by inconsistent shrinkage of the transparent paper after heat sealing of the smallest end face. Reducing the heat sealing area of the smallest end face helps to improve this situation. However, when the heat sealing area is reduced, the probability of the package box having airtightness problems increases. The inventors have further found that the area of the transparent paper outside the smallest end face of the package box that affects airtightness after heat sealing is not completely consistent with the part that causes the curtain-shaped wrinkles.

[0033] The present application sets the first working surface 1 and the second working surface 2 which contact and heat seal the transparent paper in turn, forming two heat sealing stations. In use, the part of the smallest end face of the package box that needs to be fully heat sealed can be repeatedly heat sealed, and the part that can meet the demand with single heat sealing can be single heat sealed. In this way, the heat sealing iron is set to avoid overheat sealing and cause problems such as curtain-shaped wrinkles, while the total heat sealing area is large, improving airtightness and reliability.

[0034] In some embodiments, the repeated heat sealing part 31 includes an area for heat sealing the crease of the transparent paper. The transparent paper is often folded and sealed at the smallest end face of the package box, and the crease is the main part that affects airtightness, so it needs to be fully heat sealed.

[0035] Generally, the crease of the transparent paper mainly corresponds to the middle region of the smallest end face of the package box and the "H" shaped region near the two short sides. Therefore, in some embodiments, the repeated heat sealing part 31 includes a "H" shaped region for heat sealing the middle and the part near the two short sides of the smallest end face of the package box.

[0036] Further, the crease of the transparent paper usually extends to the four corners corresponding to the smallest end face of the package box, and the heat sealing iron is often set to be "H" shaped in the prior art. In order to ensure airtightness while reducing wrinkles caused by heat sealing of the iron to the transparent paper of the largest face 102. In some embodiments, the single heat sealing part includes an area corresponding to the extension line of the two short sides of the "H" shaped region. The inventors have found that single heat sealing of this part of the transparent paper can increase the total area covered by heat sealing while reducing the area of the repeated heat sealing part, taking into account airtightness and the aesthetics of the largest face 102.

[0037] In some forming methods of the package box, such as the soft cigarette package box 100 folded by the wrapping paper, the end part has the corner 101, which causes the end part of the package box to have different thicknesses, and the area of the smallest end surface of the package box close to the long side is not uniformly contacted by the iron during the heat sealing, and finally a curtain-shaped wrinkle is formed on the largest surface 102 of the package box. In some embodiments, the smallest end surface of the package box includes the corner 101 formed by the wrapping paper, and the single heat sealing part includes an area corresponding to the shape of the corner 101. For example, the single heat sealing part is arranged to avoid the corner 101 to form the area with thicker thickness, and the edge of the corner 101 is heat sealed close to the area with thinner thickness, and the inventor finds that the area is heat sealed only once to achieve a better sealing effect.

[0038] In some embodiments, on the first working surface 1, all the single heat sealing parts 32 are arranged on the first side of the repeated heat sealing part 31; on the second working surface 2, all the single heat sealing parts 32 are arranged on the second side of the repeated heat sealing part 31, and the first side is opposite to the second side in the direction of the repeated heat sealing part 31. For example, all the single heat sealing parts on the first working surface 1 are arranged on the upper side of the repeated heat sealing part, and all the single heat sealing parts on the second working surface 2 are arranged on the lower side of the repeated heat sealing part. In this way, the single heat sealing part 32 and the repeated heat sealing part 31 are arranged to reduce the number of times that the iron contacts the edge of the package box and reduce the curtain-shaped wrinkle on the largest surface of the package box.

[0039] Please refer to Figures 4-5 The application also provides a packaging machine comprising the end transparent paper heat sealing iron as described above, which has all the beneficial effects.

[0040] In some embodiments, the packaging machine comprises a conveying channel 200 for conveying the package box, and two groups of end transparent paper heat sealing irons are arranged oppositely on both sides of the conveying channel 200 and can reciprocate relative to the package box in the conveying channel 200. The conveying channel 200 conveys the package box, so that the package box moves relative to the heat sealing iron and sequentially contacts the first working surface 1 and the second working surface 2.

[0041] In some embodiments, a flattening frame 300 is fixedly arranged on both sides of the end surface of the package box, the flattening frame 300 is provided with a flattening surface 302 abutting against the transparent paper and a through hole 301 through which the end transparent paper heat sealing iron passes, and the shape and size of the through hole 301 are the same as the working surface. The flattening surface 302 can abut against the transparent paper, and the shape and size of the through hole 301 are the same as the first working surface 1 or the second working surface 2. During the heat sealing, the flattening surface 302 can limit the transparent paper to prevent the transparent paper from being raised to form a wrinkle; the through hole 301 with the same shape as the iron body allows the iron body to pass through while guiding the iron body, and the phenomenon that the transparent paper is raised to form a wrinkle mainly occurs at the edge of the working surface, so the same shape and size of the through hole 301 can make the flattening surface 302 act on the raised part of the transparent paper as much as possible.

[0042] The flattening frame 300 only needs to flatten the transparent paper when the soldering iron body acts on the transparent paper, and can be arranged with the soldering iron body or fixedly arranged. In some embodiments, the flattening frame 300 is fixedly arranged on the outside of the packaging box. The fixed arrangement of the flattening frame 300 can avoid the arrangement of the driving unit, is relatively simple, and has high precision. In some embodiments, the distance between the two flattening frames 300 corresponds to the length of the longest side of the packaging box. In this way, the flattening frame 300 is arranged, so that the transparent paper is always flattened by the flattening surface 302.
