Problems solved by technology

[0005] (3) The glue in the open glue tank is easy to form a skin, which affects the gluing effect;
[0006] (4) The fixed folder is easily contaminated by glue and needs to be cleaned frequently
[0007] In addition, at room temperature, cold glue can provide sufficient adhesion for the adhesive surface of the cigarette pack carton, but requires a long drying time, which makes the cigarette packs need to go through a longer path on the machine, or Set up heating channels on the machine to shorten the drying time, which leads to more complex and longer size of the machine equipment
The use of hot melt adhesive can quickly bond and fix the cigarette pack carton, but the subsequent folding needs to be completed as soon as possible to avoid affecting the bonding effect of the hot melt adhesive
[0008] Moreover, as tobacco packaging equipment becomes more and more intelligent, it is often required that the equipment can be modularized according to function and process, quickly change specifications, and even change the form to adapt to the new process. It is difficult to achieve these requirements in a way

[0066] Such as figure 2 As shown, the main body of the cigarette packet box to be processed is a cuboid, and the top surface A3 of the main body has a left to-be-folded surface A35 unfolded toward the left side of the main body left side A45 and a right side to be folded toward the right side of the main body right side A46. Folding surface A36;

[0067] The cigarette packet box to be processed is placed on the timing belt 1, the bottom surface A4 of the main body of the cigarette packet box to be processed is attached to the timing belt 1 downward, and the left side to be folded A35 and the right side to be folded A36 protrude out from the left and right sides of the timing belt 1;

[0068] The synchronous belt 1 drives the cigarette pack to be processed to move from ...

Embodiment 2

[0075] Based on the gluing and folding device for cigarette packs in Embodiment 1, the synchronous belt 1 is driven by the conveying servo motor M1 to move forward intermittently or continuously.

[0076] Preferably, the conveying servo motor M1 is arranged in front of the cold glue spraying device 2 , the hot melt glue spraying device 3 and the movable folding device 4 .

[0077] Preferably, the synchronous belt 1 is provided with lugs 10;

[0078] The cigarette pack box to be processed placed on the synchronous belt 1, the back side A2 of its main body leans against a lug 10;

[0079] The cigarette pack box to be processed moves forward under the promotion of the synchronous belt 1 lug 10 .

[0080] Preferably, the left and right width of the main body of the cigarette pack to be processed is 0.9 to 2.8 times the width of the timing belt 1 .

[0081] Preferably, the left and right width of the main body of the cigarette pack to be processed is 1 to 2.2 times the width of t...

Embodiment 3

[0083] Based on the cigarette pack case gluing and folding device of Embodiment 1, such as Figure 4 As shown, the cold glue spraying device 2 includes a rotating cylinder 21, a cylindrical valve body 22 and two left and right cold glue guns 23;

[0084] The rotary cylinder 21 is used to drive the cylindrical valve body 22 to rotate;

[0085] The cylindrical valve body 22 is placed under the synchronous belt 1;

[0086] Two left and right cold glue guns 23 are installed in the cylindrical valve body 22;

[0087] The rotating cylinder 21 can drive the cylindrical valve body 22 to rotate so that the cold glue injection ports of the left and right cold glue guns 23 face upward and are respectively located on both sides of the advancing path of the main body of the cigarette pack to be processed;

[0088] When the cigarette pack box to be processed moves forward through the cold glue spraying station, the left and right cold glue guns 23 spray cold glue points B1 vertically from...

Abstract

The invention discloses a cigarette packet box gluing and folding device, which is characterized in that a cold glue spraying device sprays a column of cold glue points on each of a left to-be-foldedsurface and a right to-be-folded surface of a to-be-processed cigarette packet box, then a hot melt glue spraying device sprays a column of hot glue points on each of a main body left side surface anda main body right side surface of the to-be-processed cigarette packet box, and then a movable folding device is used for completing final folding and pasting of the to-be-processed cigarette packetbox, and a finished cigarette packet box is formed. According to the cigarette packet box gluing and folding device provided by the invention, the gluing and folding requirements of cigarette packet boxes with different specifications can be met, and the cigarette packet box bonding effect is improved.

Description

technical field [0001] The invention relates to tobacco packaging machinery, in particular to a cigarette pack box gluing and folding device. Background technique [0002] In the existing automatic tobacco packaging production line, when the cigarette packs move in a straight line path in the channel, it involves the gluing and folding positions of the cigarette pack cartons. The side is glued, and the folding of the two sides of the cigarette pack carton is completed by the subsequent fixed folder. But there are several problems in actual production: [0003] (1) When the specifications of the cigarette pack carton change, it is necessary to redesign and replace a large number of special parts for the gluing part; [0004] (2) For medium and fine carton specifications, the way of gluing the rubber roller is more difficult to bond the narrow side, and the viscosity of the glue is required to be high, otherwise it is easy to throw the glue at high speed; [0005] (3) The g...
