[0035] Moisture-retaining packaging for cigarette packs has been a unique approach adopted in recent years by the tobacco industry to preserve the moisture content of cigarettes and enhance their flavor and taste. Wrapping the inner cigarette pack with moisture-retaining film provides a greater degree of air isolation than conventional aluminum foil packaging, ensuring that the moisture and flavor of the cigarettes remain within the pack.

[0036] Currently, the main methods for packaging inner-frame cigarette packs with moisturizing film are adhesive packaging and manual packaging. The adhesive packaging method has poor sealing effect and poor moisturizing effect. Manual packaging has low production efficiency and high production costs.

[0037] In view of this, the present disclosure proposes an inner-frame paper cigarette pack packaging device and method, which packs the inner-frame paper cigarette pack in a mechanized and intelligent manner, with good sealing effect and high efficiency.

[0042] A bottom soldering iron 14 for heat-sealing a single sheet of moisturizing film at the bottom of the inner frame cigarette pack is provided on the fixed arc-shaped folding plate, so that the single sheet of moisturizing film seals the bottom of the inner frame cigarette pack;

[0043] A movable bottom side corner folding device 15 is provided at the bottom position near the forming wheel to push the single moisturizing film to fold at the bottom side corner of the inner frame cigarette pack;

[0044] On the fixed arc-shaped folding plate and on the side of the forming wheel, a movable long-side folder 16 is provided to push the single moisturizing film to fold the long side on the side of the inner frame cigarette pack;

[0045] A fixed long-side folding device 17 is provided near the front lower portion of the forming wheel and on the side of the forming wheel to push the single moisturizing film to fold the long side of the side of the inner frame cigarette pack;

[0046] The fixed long side folder is provided with a long side iron 18 for heat-sealing a single moisturizing film on the side of the inner frame cigarette pack, so that the single moisturizing film seals the side of the inner frame cigarette pack.

[0047] In some embodiments, it also includes a forming wheel fixed shaft, on which a bearing is sleeved. The forming wheel is mounted on the bearing so that when the driving member is energized, the forming wheel can drive the single moisturizing film and the inner frame cigarette pack to rotate.

[0048] In some embodiments, a cam is provided on the forming wheel fixing shaft.

[0049] In some embodiments, the moisturizing film unwinding roller is driven by a first servo motor.

[0050] In some embodiments, the conveyor roller is driven by a second servo motor.

[0051] In some embodiments, the number of the moisturizing film unwinding rollers is two, and the number of the conveying rollers is two.

[0052] like Figure 2 and Figure 3 As shown, one end of the follower is connected to the folding piece, and the other end cooperates with the cam. The follower and the folding piece rotate with the forming wheel, so that the position of the folding piece can move back and forth. In order to fold a single moisturizing film at the top side corner of the inner frame cigarette pack, the folding piece is extended to the highest position. When the folding piece rotates to the bottom position along with the forming wheel, it shrinks to the lowest position and remains at the lowest position until the packaged inner frame cigarette pack is pushed out horizontally from the workstation. Then it is extended to the highest position again and the cycle repeats.

[0053] like Figure 14 As shown, a method for packaging an inner-frame cigarette pack includes:

[0054] In step 110 , the moisturizing film unwinding roller driven by the first servo motor conveys the moisturizing film on the moisturizing film carrier to the negative pressure buffer device.

[0055] In step 120 , the moisturizing film outputted from the negative pressure buffer device enters a deviation correction device to adjust its position.

[0056] In step 130 , a conveying roller driven by a second servo motor conveys the moisturizing film output from the deflection correction device to the rotary cutter position.

[0057] Step 140 : The rotary cutter cuts the moisturizing film into individual sheets of moisturizing film.

[0058] In step 150 , a single moisturizing film is conveyed to the acceleration wheel position by the negative pressure suction conveyor belt.

[0059] Step 160: The acceleration wheel transports the single moisturizing film to the work station.

[0060] Step 170: Use a push rod to push out the inner frame cigarette pack and combine it with the single moisturizing film.

[0061] Step 180: fold the single moisturizing film into a U-shape on the inner frame cigarette pack with the help of the mold box on the forming wheel. Figure 5 shown.

[0062] Step 190: Use the folding sheet to push the single moisturizing film to fold at the top side corner of the inner frame cigarette pack. Figure 6 shown.

[0063] Step 200: drive the forming wheel to rotate clockwise. Figure 4 shown.

[0064] Step 210: Use the movable upper folder to push the single moisturizing film to fold the long side of the bottom of the inner frame cigarette pack. Figure 7 shown.

[0065] Step 220: Use a fixed arc-shaped folding plate to push the single moisturizing film to fold at the bottom long side of the inner frame cigarette pack. Figure 8 shown.

[0066] Step 230: Use a bottom soldering iron to heat seal the single moisturizing film (the position indicated by the irregular circle) at the bottom of the inner frame cigarette pack, so that the single moisturizing film seals the bottom of the inner frame cigarette pack. Figure 9 shown.

[0067] Step 240: Use the bottom corner folding device to push the single moisturizing film to fold at the bottom corner of the inner frame cigarette pack. Figure 10 shown.

[0068] Step 250: Use the movable long edge folding device to push the single moisturizing film to fold the long edge on the side of the inner frame cigarette pack. Figure 11 shown.

[0069] Step 260: Use a fixed long edge folding device to push the single moisturizing film to fold the long edge of the side of the inner frame cigarette pack. Figure 12 shown.

[0070] Step 270: Heat-seal the single moisturizing film (the position indicated by the irregular circle) on the side of the inner frame cigarette pack with the help of a long-side soldering iron, so that the single moisturizing film seals the side of the inner frame cigarette pack. Figure 13 shown.

[0071] Please note that in the embodiments disclosed herein, the folding of a single sheet of moisturizing film along the long sides of the inner cigarette pack is not specifically emphasized. In step 250, the movable long-side folding mechanism is used to push the single sheet of moisturizing film along the long sides of the inner cigarette pack. The long upper sides of the side surfaces referred to here actually refer to the long upper sides of the left and right sides. If readers encounter similar situations, please refer to the above explanation for understanding.

[0072] It should be noted that the term "soldering iron heat-sealed single sheet of moisturizing film" is a general term, essentially comprising two parts. In step 230, the single sheet of moisturizing film at the bottom of the inner frame cigarette pack is heat-sealed using a bottom soldering iron, so that the single sheet of moisturizing film seals the bottom of the inner frame cigarette pack. The single sheet of moisturizing film in this case includes a single sheet of moisturizing film folded along the upper long edge of the bottom and a single sheet of moisturizing film folded along the lower long edge of the bottom. If readers encounter similar situations, please refer to the above explanation for understanding.

[0073] In the present disclosure, the inner frame cigarette packs are packaged in a mechanized and intelligent manner, with good sealing effect and high efficiency.
