Method and device of cigarette-case seal folding device on soft cigarette packaging machine

Abstract

The invention relates to a folding method of sealing labels for a cigarette case on a soft carton cigarette-packing machine, and a device thereof. The method comprises the following steps: two air flows at the cigarette case outlet opening on the packing machine blow to a sealing label arranged at the top end of the cigarette case during the traveling, and the parts of the sealing label to be extended out of the top end of the cigarette case are blown down in sequence during the process that the two air flows pass through the top end of the cigarette case, bent towards the cigarette case and enable the sealing label to be stuck on the cigarette case along with the travel of the cigarette case and through the sequence propping of each cigarette case. The device is provided with an air-jet seat, a gap is arranged at the middle part of the air-jet seat, fumaroles are respectively arranged on the both sides of the gap, the spacing between the two fumaroles is smaller than the width of the sealing label for the cigarette case, an air inlet hole arranged on the air-jet seat communicates with the two fumaroles, and the air inlet hole of the air-jet seat is connected with an air supply device through a pipeline. The folding method of the sealing labels for the cigarette case on the soft carton cigarette-packing machine, and the device thereof are simple, reasonable and reliable, and can ensure the reliability and the quality of the sealing label stuck on the cigarette case.

Description

technical field [0001] The invention relates to the folding technology of soft-pack cigarette seals, in particular to a folding method and device for cigarette pack seals on soft-pack cigarette packaging machines. Background technique [0002] The seal folding mechanism on the existing BO-500 soft box cigarette packaging machine in the cigarette industry is mainly composed of cams, swing rods, connecting rods, springs, and folder components. The principle of sealing the cigarette box is: after the seal is pasted on the top of the cigarette box, the left side of the seal is naturally folded by touching the adjacent cigarette box during the leftward movement of the cigarette box, and the right side of the seal is pressed against by the folder. Push to fold. The deficiencies in the above-mentioned existing seal folding methods are: 1. Since the left side of the seal is naturally folded by touching the adjacent cigarette case, the left side of the seal sometimes forms a flangin...

AI Technical Summary

Problems solved by technology

The deficiencies in the above-mentioned existing seal folding methods are: 1. Since the left side of the seal is naturally folded by touching the adjacent cigarette case, the left side of the seal sometimes forms a flanging phenomenon; 2. Because the cigarette pack The output belt of the machine is driven by a servo motor. When the machine is running at a stable speed, the position of the cigarette pack is accurate, and the right side of the seal can be accurately pushed and folded by the folder. ), the position of the cigarette pack in the conveyor belt will be inaccurate. When the pack is sent far away, the seal on the right wing of the pack cannot be folded. When the pack is sent close, the top of the pack will be smashed by the seal folder; 3. The surface of the folder is easy to stick to glue, causing quality problems such as the length and skew of the seal; 4. The seal folding mechanism has many parts, the action is complicated, and the use cost is high
