[0002] In the cigarette production industry, special-shaped packaging of cigarette products is becoming increasingly diversified, and a variety of special-shaped prefabricated cartons have appeared. For different prefabricated cartons, automated production equipment also needs to be updated to meet production needs.

[0003] In the packaging production line of special-shaped prefabricated boxes, due to the diversity of small packages in form and size, the size of prefabricated boxes also varies greatly. Among many special-shaped boxes, some boxes have a large difference in length-to-width ratio, or the side area of ​​the short side of the box is relatively large, so the prefabricated boxes are prone to large surface dents, and the iron is prone to not being able to seal firmly during the transparent paper wrapping process. Utility Model Content

[0004] In view of this, the embodiments of the present disclosure provide a transparent paper corner folding and sealing device and a strip box transparent paper packaging machine, which can improve the transparent paper sealing quality of prefabricated strip boxes.

[0005] In one aspect of the present disclosure, a transparent paper corner folding and hot-sealing device is provided, comprising:

[0006] A folding mechanism, configured to fold the transparent paper wrapping the strip box;

[0007] A sealing and ironing mechanism, located downstream of the folding mechanism along the moving direction of the strip box, and configured to seal and iron the transparent paper with the folded corners on the side of the strip box;

[0008] Wherein, the sealing mechanism comprises a first sealing component, wherein the first sealing component has a sealing plane and a raised portion, and the raised portion is raised toward the strip box relative to the sealing plane.

[0009] In some embodiments, the raised portion is in a prism shape, and the area of ​​the top plane of the raised portion is smaller than the area of ​​the sealing plane.

[0010] In some embodiments, in a first direction, a top plane of the protrusion is located in the middle of the sealing plane, and the first direction is perpendicular to a movement direction of the strip box.

[0011] In some embodiments, the protrusion is located upstream of the sealing plane along the movement direction of the strip box.

[0012] In some embodiments, the protrusion is in a prism shape, and has a trapezoidal guiding slope at one end of the protrusion away from the sealing plane.

[0013] In some embodiments, in a first direction, a bottom width of the protrusion is the same as a width of the sealing plane, and the first direction is perpendicular to a movement direction of the strip box.

[0014] In some embodiments, the raised portion is also used to seal the transparent paper on the side of the box.

[0015] In some embodiments, the sealing plane and the raised portion are an integrally formed structure.

[0016] In some embodiments, the sealing mechanism further includes a second sealing component, which is located between the folding mechanism and the first sealing component and is configured to pre-seal and shape the transparent paper with the folded corners on the side of the box.

[0017] In some embodiments, the second sealing component includes a sealing strip, and the length direction of the sealing strip is parallel to the movement direction of the strip box.

[0018] In some embodiments, the second sealing component includes a plurality of sealing strips, and the plurality of sealing strips are arranged at intervals along a first direction, and the first direction is perpendicular to the movement direction of the strip box.

[0019] In some embodiments, a section of the folding mechanism adjacent to the sealing mechanism is provided with a strip groove, and the sealing strip is embedded in the strip groove.

[0022] In one aspect of the present disclosure, a strip box transparent paper packaging machine is provided, comprising:

[0023] The aforementioned transparent paper corner folding and hot sealing device.

[0024] According to the disclosed embodiment, the sealing mechanism is used to seal the transparent paper on the side of the strip box after the folding mechanism is folded, and the transparent paper is pressed against the side of the strip box by the raised part in the sealing mechanism. In this way, even for the side of the strip box that is larger in size and has a concave deformation, the raised part can still press the transparent paper against the side of the strip box, so that the side of the strip box effectively supports the transparent paper, thus improving the sealing quality when the transparent paper is sealed on the sealing plane, and reducing the risk of loose sealing. In addition, this is also conducive to improving the adaptability to transparent paper packaging of strip boxes of different shapes and sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In the packaging production line of special-shaped prefabricated boxes, due to the diversity of small packages in form and size, the size of prefabricated boxes also varies greatly. Among many special-shaped boxes, some boxes have a large difference in length-to-width ratio, or the side area of ​​the short side of the box is relatively large, so the prefabricated boxes are prone to large surface dents, and the iron is prone to not being able to seal firmly during the transparent paper wrapping process.

[0036] In view of this, the embodiments of the present disclosure provide a transparent paper corner folding and sealing device and a strip box transparent paper packaging machine, which can improve the transparent paper sealing quality of prefabricated strip boxes.

[0037] Figure 1 Schematic diagram of the structure of some embodiments of the strip box transparent paper packaging machine disclosed in the present invention. Figure 1 The embodiment of the present disclosure provides a strip box transparent paper packaging machine, including a transparent paper corner folding and hot sealing device, which is used to realize the corner folding and side hot sealing of the transparent paper wrapping the strip box. Figure 1 In the invention, the strip box transparent paper packaging machine may further include a strip box lifting device 30, a strip box pushing device 40 and a transparent paper upper and lower surface sealing iron 50.

[0038] The strip box is pushed twice in reverse direction by the strip box lifting device 30 and the strip box pushing device 40, and the transparent paper wraps the four sides of the strip box. Next, the strip box is folded and sealed by the transparent paper corner folding and sealing device. Then, the strip box is sealed by the transparent paper upper and lower surfaces sealing iron 50.

[0039] Figure 2 1 is a schematic diagram of the exploded structure of some embodiments of the transparent paper corner folding and hot sealing device according to the present disclosure. The embodiments of the present disclosure provide a transparent paper corner folding and hot sealing device, which can be applied to but not limited to the above-mentioned transparent paper box packaging machine. Figure 1 and Figure 2The transparent paper corner folding and ironing device comprises: a corner folding mechanism 10 and an ironing mechanism 20. The corner folding mechanism 10 is configured to fold the transparent paper wrapped in the strip box. The ironing mechanism 20 is located downstream of the corner folding mechanism 10 along the moving direction of the strip box, and is configured to iron the transparent paper with the corner folded on the side of the strip box. The ironing mechanism 20 comprises a first ironing component 21, and the first ironing component 21 has an ironing plane 211 and a protrusion 212, and the protrusion 212 protrudes toward the strip box relative to the ironing plane 211.

[0040] Here, the strip box refers to an outer box used to pack a certain number of cigarette boxes. The strip box is usually in the shape of a cuboid and may include three sets of opposite rectangular box faces. This embodiment can be used for the folding and sealing of the transparent paper at the side box faces other than the large face of the strip box.

[0041] The folding mechanism 10 can cooperate with the mechanism driving the strip box to realize the folding of the transparent paper on the side of the strip box. The sealing mechanism 20 can include a relatively hot element such as a soldering iron, and realizes the sealing effect by heating and squeezing the transparent paper, so that the folded transparent paper maintains its shape.

[0042] For the first sealing component 21, the sealing plane 211 can be realized by the surface of the soldering iron, and the protrusion 212 can also be realized by the surface of the soldering iron or not be set as the sealing surface to play a squeezing role. For the sealing mechanism 20, the protrusion 212 is raised in the direction of the strip box, so that the protrusion 212 can form abutment and squeezing against the transparent paper and the side of the strip box.

[0043] The sealing mechanism is used to seal the transparent paper on the side of the strip box after the folding mechanism is folded, and the transparent paper is pressed against the side of the strip box by the raised part in the sealing mechanism. In this way, even for the side of the strip box that is larger in size and has a concave deformation, the raised part can still press the transparent paper against the side of the strip box, so that the side of the strip box effectively supports the transparent paper, thus improving the sealing quality when the transparent paper is sealed on the sealing plane and reducing the risk of loose sealing. In addition, this is also conducive to improving the adaptability of transparent paper packaging for strip boxes of different shapes and sizes.

[0044] refer to Figure 2 In some embodiments, the protrusion 212 is in a prism shape, and the area of ​​the top plane tp of the protrusion 212 is smaller than the area of ​​the sealing plane 211. In this way, the protrusion 212 can squeeze the side of the box through the top plane tp with a smaller area, so as to concentrate the squeezing force on the concave area on the side of the box, thereby facilitating a tighter and firmer sealing effect.

[0045] exist Figure 2In the figure, multiple reference directions are shown, namely, a first direction z, a second direction x, and a third direction y. The second direction x is the moving direction of the strip box, the first direction z is perpendicular to the second direction x, and in some embodiments, the first direction z is parallel to the vertical direction. The third direction y is perpendicular to both the first direction z and the second direction x. For the sealing mechanism 20, in order to achieve the sealing of transparent paper on both sides of the strip box, two sets of sealing mechanisms 20 can be arranged at intervals along the third direction y, and the strip box passes through the working area between the two sets of sealing mechanisms 20.

[0046] refer to Figure 2 In the direction shown, in some embodiments, in the first direction z, the top plane tp of the protrusion 212 is located in the middle of the sealing plane 211, and the first direction is perpendicular to the movement direction of the strip box. Since the concave side of the strip box usually appears in the middle, the top plane tp of the protrusion is also set in the middle, which can form a targeted abutment and compression effect on the concave area of ​​the side of the strip box, thereby improving the sealing quality.

[0047] refer to Figure 2 In some embodiments, the protrusion 212 is located upstream of the sealing plane 211 along the moving direction of the strip box. In this way, the protrusion 212 can form a squeezing and pressing effect on the side of the strip box that passes first, and then the sealing plane 211 can seal the transparent paper on the side of the strip box as the strip box moves, effectively reducing the risk of loose sealing.

[0048] In order to make the protrusion 212 smoothly abut against the side of the box, refer to Figure 2 In some embodiments, the protrusion 212 is in a prism shape, and the protrusion 212 has a trapezoidal guiding slope gb at one end away from the sealing plane 211. In this way, the side of the strip box can gradually transition to the top plane tp through the guiding slope gb, avoiding the rapid change in the height of the protrusion, which causes the side of the strip box to be deformed or deflected due to a large lateral extrusion force or friction force.

[0049] In order to make the raised portion 212 and the sealing plane 211 form a good matching relationship, refer to Figure 2 In some embodiments, in a first direction z, the bottom width of the raised portion 212 is the same as the width of the sealing plane 211, and the first direction z is perpendicular to the movement direction of the strip box.

[0050] In the above embodiment, the raised portion 212 can also be used to seal the transparent paper on the side of the strip box. In this way, the raised portion 212 not only has a stable squeezing effect on the side of the strip box but also realizes sealing at the same time. Combined with the overall sealing of the sealing plane at the back, a good sealing effect can be achieved.

[0051] Accordingly, in order to conveniently control the temperature of the raised portion 212 and the sealing plane 211, in some embodiments, the sealing plane 211 and the raised portion 212 may be an integrated structure, that is, the sealing plane 211 and the raised portion 212 are formed by the same soldering iron.

[0052] Considering that for some shapes and sizes of boxes, the size of the folded corner of the transparent paper is too large, and directly entering the side sealing iron may cause the tip of the transparent paper to be baked and deformed, thus causing quality problems. Figure 2 In some embodiments, the sealing mechanism 20 further includes a second sealing component 22, which is located between the folding mechanism 10 and the first sealing component 21 and is configured to pre-seal and shape the transparent paper with the folded corners on the side of the box.

[0053] In this way, after the folding mechanism 10 completes the folding, the second sealing component 22 pre-seals the folded corner of the transparent paper before the first sealing component 22 seals it, so that the folded corner of the transparent paper remains in place to prevent it from coming off, thereby facilitating the subsequent sealing process to proceed smoothly.

[0054] Pre-sealing is mainly for the corners that are prone to problems, so please refer to Figure 2 In some embodiments, the second sealing component 22 includes a sealing strip 221, and the length direction of the sealing strip 221 is parallel to the movement direction of the strip box. A narrow sealing strip 221 can be used to form a strip-shaped pre-sealing portion on the side of the strip box, and the length direction of the sealing strip 221 is parallel to the movement direction of the strip box, which is conducive to pre-sealing the strip box during smooth movement.

[0055] To increase the shaping and positioning effect of the pre-seal, refer to Figure 2 In some embodiments, the second sealing component 22 includes a plurality of sealing strips 221, and the plurality of sealing strips 221 are arranged at intervals along a first direction z, and the first direction z is perpendicular to the movement direction of the strip box. Figure 2 In the embodiment, the second sealing component 22 includes two parallel sealing strips 221, which can form two parallel pre-sealing lines on the side of the strip box, making the pre-sealing more reliable and reducing the possibility of disengagement.

[0056] In order to make the pre-sealing operation of the second sealing component 22 and the folding operation of the folding mechanism 10 cooperate more smoothly, refer to Figure 2In some embodiments, a section of the corner folding mechanism 10 adjacent to the sealing mechanism 20 is provided with a strip groove 131, and the sealing strip 221 is embedded in the strip groove 131. In this way, the sealing strip 221 can be reliably installed through the strip groove 131, and can be exposed or extended from the opening of the strip groove 131, so that the connection between the pre-sealing operation and the corner folding operation is smoother and tighter.

[0057] refer to Figure 2 In some embodiments, the folding mechanism 10 includes: a first folding plate 11, a second folding plate 12 and a forming plate 13, wherein the forming plate 13 is located downstream of the first folding plate 11 along the moving direction of the strip box, and the second folding plate 12 is located between the first folding plate 11 and the forming plate 13, and the folding angle of the first folding plate 11 is less than 60°. Preferably, the folding angle of the first folding plate 11 is 45°. Here, the first folding plate 11 and the second folding plate 12 respectively realize the folding of the upper and lower edges of the transparent paper to form upper and lower folding angles, and the forming plate 13 cooperates with the first folding plate 11 and the second folding plate 12 to form the transparent paper in a state to be sealed and ironed after folding. The folding angle of the first folding plate 11 is less than 60°, so that the folding angle is slowed down, which is conducive to reducing the tailing caused during the forward conveying of the folding angle.

[0058] For the folding mechanism 10, in order to realize the folding of the transparent paper on both sides of the box, Figure 2 In the embodiment, two groups of folding mechanisms 10 may be arranged at intervals along the third direction y, and the strip box passes through the working area between the two groups of folding mechanisms 10.

[0059] According to the various embodiments of the above-mentioned transparent paper corner folding and hot sealing device, the embodiments of the present disclosure further provide a strip box transparent paper packaging machine, comprising: the transparent paper corner folding and hot sealing device of any of the above-mentioned embodiments.
