Description

Technical Field

[0001] The present invention relates to a cigarette case forming device, in particular to a white cardboard cigarette case forming device with a partition, and belongs to the technical field of design and manufacture of cigarette packaging equipment. Background Art

[0002] At present, the packaging process of hard box small pack cigarettes is as follows: First, arrange the cigarette sticks in the order of 7-6-7 in the aluminum foil paper, put them into the inner frame paper, wrap the trademark paper, and finally form the hard box small pack cigarettes. After opening this kind of hard box small pack cigarettes, the taste of the cigarettes is reduced due to serious loss of moisture in the cigarette sticks. In order to ensure that some medium and high-grade cigarettes still have a good taste after opening, it is necessary to carry out moisture retention and moisturizing treatment to ensure the quality of the cigarettes. Therefore, cigarettes packaged with double aluminum foil paper appear on the market. For example, a cigarette pack forming device for double aluminum-wrapped cigarettes disclosed in CN208585478 U changes the ordinary 7-6-7 arranged cigarette pack into two 2×5 arranged cigarette packs. Each cigarette pack is wrapped with aluminum foil paper and then compounded into the inner frame paper, and finally the trademark paper is wrapped to form two independent hard box small pack cigarettes with aluminum foil paper packaging. When one of the opened aluminum foil paper-packaged cigarettes is taken out after opening, the other is still in the unopened aluminum foil paper packaging, which can maintain the taste of the cigarette pack, that is, achieve a certain degree of moisture retention and moisturizing effect. In addition, in order to achieve the purpose of complete moisture retention and moisturizing, different types of moisture retention and moisturizing packaging boxes appear on the market. In particular, a packaging form different from the traditional cigarette wrapping process appears. This kind of cigarette does not need to be wrapped with aluminum foil paper, but is installed in a cigarette case folded from white cardboard, and a partition is arranged in the middle of the cigarette case, so as to form two independent cavities for placing cigarette sticks. The cigarette sticks in each cavity are loaded in the arrangement of 2×5. Finally, a moisture retention sticker is compounded outside the white cardboard cigarette pack to form a moisture retention cigarette pack. Because the moisture retention sticker is used for sealing, it can be sealed again after opening, so as to achieve the purpose of complete moisture retention and moisturizing.

[0003] However, the packaging process of this kind of moisture retention cigarette pack has a large gap from the existing cigarette wrapping process and cannot be automatically packaged on the existing cigarette packaging machines. Therefore, it is necessary to develop new equipment to automatically complete this type of cigarette packaging. Summary of the Invention

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0050] In the embodiments of the present invention, the structures not specifically described are common structures.

[0051] As shown in the accompanying drawings, a forming device for a white cardboard cigarette box with a partition provided by the present invention includes: a conveyor 2 provided on a frame; a storage bin 1 with a storage space for white cardboard A located at the input end of the conveyor 2; a paper picking mechanism 3 for taking out the white cardboard A from the storage bin 1 and placing it on the conveyor 2; a partition forming mechanism for making the formed white cardboard cigarette box cavity have a partition during the conveyance of the white cardboard A; a gluing mechanism P1 for gluing the bonding surface of the white cardboard during the conveyance of the white cardboard A; a pushing and downward folding mechanism 6 for pushing the white cardboard with a partition into the folding and forming mechanism 7; a guiding mechanism 8 for pushing the white cardboard with a partition into the folding and forming mechanism 7; a folding and forming mechanism 7 for folding the white cardboard A into a cigarette box; wherein:

[0052] The storage bin 1 is surrounded by four columns and crossbars between two columns, and the middle thereof is a storage space, and the shape of the storage space is adapted to the shape of the white cardboard A, such as Figure 1 and Figure 2 ;

[0053] The conveyor 2 is located below the storage bin 1, and it includes two conveyor belts 21 arranged in parallel and at intervals, and upwardly convex push blocks 22 are arranged at equal intervals on the two conveyor belts 21, and the white cardboard A is stuck between two adjacent push blocks 22, such as Figure 2 and Figure 3;

[0054] The paper picking mechanism 3 is used to pick up the white cardboard A from the storage library 1 and place it on the conveyor 2. The paper picking mechanism 3 is located below the storage library 1 and is set at the gap position between the two conveyor belts 21 of the conveyor 2. It includes a first power cylinder 31, a connecting seat 33 with an air chamber inside, which is set on the piston rod of the first power cylinder 31, a negative pressure hole 32 communicated with the air chamber, the negative pressure hole 32 is communicated with a negative pressure source through a hose, and four suction cups 34 with vertical through holes are set on the connecting seat 33. The vertical through holes of the four suction cups 34 are all communicated with the air chamber of the connecting seat 33. So that when the piston rod of the first power cylinder 31 drives the connecting seat 33 and the suction cups 34 to rise to contact the bottom surface of the white cardboard A, the negative pressure source is turned on to form a negative pressure in the vertical through holes of the multiple suction cups 34 and the air chamber of the connecting seat 33, thereby sucking the white cardboard A above. Then, it descends with the piston rod of the power cylinder 31 to the gap position between the two conveyor belts 21 of the conveyor 2, and places the white cardboard A between two adjacent pushing blocks 22 of the conveyor 2. The negative pressure source is disconnected to release the suction force, completing the operation of picking up the white cardboard A from the storage library 1 and placing it on the conveyor 2, as Figure 2 、 Figure 4 ;

[0055] In order to make the formed white cardboard cigarette case have a partition in the middle, a partition forming mechanism needs to be set during the conveying process of the white cardboard A. The partition forming mechanism includes a partition stamping mechanism 4 above and a partition extrusion and closing mechanism 5 below. Among them:

The gluing mechanism P1 is a spray gun connected with a glue supply pipe. The spray gun is located above the white cardboard A and is used to apply glue to the A1 or A2 surface of the white cardboard A, as Figure 2 、 Figure 6 、 Figure 14 、 Figure 15 ;

[0058] To form a partition B4 that protrudes into the box cavity on the white cardboard A, a partition extrusion and closing mechanism 5 needs to be set during the conveyance of the white cardboard A. The partition extrusion and closing mechanism 5 is arranged between the two conveyor belts 21 of the conveyor 2 and is located below the partition stamping mechanism 4. It includes two strip-shaped vertical plates 51 arranged opposite to each other with a gap therebetween. The gap 52 between the two strip-shaped vertical plates 51 gradually narrows along the conveying direction Q1, and the input ends (where the gap is the largest) of the two strip-shaped vertical plates 51 are directly opposite to the stamping block 41 of the partition stamping mechanism 4 above. When the white cardboard A with glue applied on surface A1 or A2 enters the upper surfaces of the two strip-shaped vertical plates 51, first, through the downward pressing of the stamping block 41, the end of the partition dotted line L1 on the white cardboard A sinks downward, forming a V shape with the two side paper surfaces A1 and A2, and then enters the gap 52 between the two strip-shaped vertical plates 51. As the gap 52 gradually narrows along the conveying direction Q1, it is squeezed, closed, and bonded into an upright partition B4. The thickness of the partition B4 is twice the thickness of the white cardboard A, such as Figure 5 , Figure 6 , Figure 7 , Figure 14 , Figure 15 ;
