[0053] like Figure 2 and Figure 3 As shown, one end of the follower is connected to the folding sheet, and the other end cooperates with the cam. The follower and the folding sheet rotate along with the forming wheel, so that the position of the folding sheet can move back and forth. In order to fold a single moisturizing film at the top side corner of the inner frame cigarette package, the folding sheet is extended to the highest position. When the folding sheet rotates to the bottom position along with the forming wheel, it shrinks to the lowest position and remains until the packaged inner frame cigarette package is pushed out horizontally from the workstation, and then it is extended to the highest position again, and the cycle is repeated.

[0054] like Fig.14 As shown, a method for packaging an inner frame cigarette package comprises:

[0055] 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.

[0056] Step 120 , the moisturizing film outputted from the negative pressure buffer device enters a deviation correction device to adjust its position.

[0057] Step 130 : The conveying roller driven by the second servo motor conveys the moisturizing film output from the deflection correction device to the rotary cutter position.

[0059] Step 150 , a single moisturizing film is conveyed to the acceleration wheel position by the negative pressure suction conveyor belt.

[0060] Step 160 , the acceleration wheel transports the single moisturizing film to the work station.

[0061] Step 170, using a push rod to push out the inner frame cigarette pack and combine it with the single moisturizing film.

[0062] Step 180, using the mold box on the forming wheel to fold the single moisturizing film into a U-shape on the inner frame cigarette pack, such as Figure 5 shown.

[0063] Step 190, using the folding sheet to push the single moisturizing film to fold at the top side corner of the inner frame cigarette pack, such as Figure 6 shown.

[0064] Step 200, driving the molding wheel to rotate clockwise, such as Figure 4 shown.

[0065] Step 210, using a movable upper folder to push a single moisturizing film to fold the long side of the bottom of the inner frame cigarette pack, such as Figure 7 shown.

[0066] Step 220, using a fixed arc folding plate to push a single moisturizing film to fold at the bottom long side of the inner frame cigarette pack, such as Figure 8 shown.

[0067] Step 230, using 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, such as Fig. 9 shown.

[0068] Step 240, using a bottom side corner folding device to push a single moisturizing film to fold at the bottom side corner of the inner frame cigarette pack, such as Fig.10 shown.

[0072] Please note that in the embodiments of the present disclosure, the folding of the single moisturizing film on the long sides of the inner frame cigarette pack is not deliberately emphasized. As in step 250, the movable long side folding device is used to push the single moisturizing film to fold the long sides of the inner frame cigarette pack. The long upper sides of the side here actually refer to the long upper sides of the left side and the long upper sides of the right side. If readers encounter similar situations, please understand them according to the above explanation.

[0073] It should be noted that the single moisturizing film in "soldering iron heat-sealed single moisturizing film" is a general concept, which actually includes two parts. As in step 230, the single moisturizing film at the bottom of the inner frame cigarette pack is heat-sealed with the bottom soldering iron, so that the single moisturizing film seals the bottom of the inner frame cigarette pack. The single moisturizing film here includes a single moisturizing film bent along the upper long side of the bottom and a single moisturizing film bent along the lower long side of the bottom. If readers encounter similar situations, please understand them according to the above explanation.

[0074] In the present disclosure, the inner frame cigarette packs are packaged in a mechanized and intelligent manner, with good sealing effect and high efficiency.
