[0002] Tipping paper is the packaging material used for cigarettes. It is the outer wrapping paper that connects the cigarette body and the filter tip. Tipping paper is one of the basic carriers of the cultural connotation of cigarette products. In order to reduce the amount of nicotine inhaled and improve the taste of smoking, a laser hole is set on one side of the tipping paper.

[0003] The equipment used to form laser holes on tipping paper is the tipping paper laser punching device.

[0004] The tipping paper laser punching device includes a device frame, on which there are a raw material roller and a product roller, a laser head and a punching liner. The laser head faces the punching liner, and the tipping paper is released from the raw material roller and passes through the punching liner to punch holes in the tipping paper. The tipping paper with laser holes is wound on the product roller.

[0005] The tipping paper (raw paper) to be punched is generally coiled into a disc, namely a raw paper disc. In the prior art, the raw paper is used directly during laser punching. During the punching process, the laser generates stress on the tipping paper, causing deformation of the punched area, resulting in non-standard laser holes and affecting product quality.

The top of the fixed lining plate and the bottom of the movable pressing plate are the parts where the raw material disk is placed flat and the raw material disk is pressed. The fixed lining plate, the fastening column, the movable pressing plate and the fastening nut form a pressing assembly.

[0008] Furthermore, the surfaces of the fixed lining plate and the movable pressing plate have a plurality of evenly distributed small holes, and the diameter of the small holes is 3 to 5 mm.

[0013] The technical solution of the tipping paper laser drilling method of the present invention is achieved as follows: the tipping paper laser drilling method uses a laser drilling machine to perform laser drilling on the tipping paper. Before the tipping paper is punched, the tipping paper base paper is first pre-treated. The pre-treatment is a pressing treatment, that is, the side of the tipping paper is pressed in a direction parallel to the surface of the tipping paper, so that the side of the tipping paper base paper shrinks to cope with the stress and deformation during the punching of the tipping paper base paper.

[0025] like Figure 1 、 2 As shown in , 3, the laser punching pretreatment device for tipping paper is characterized in that: it includes a fixed liner 11, the fixed liner has a fastening column 12 perpendicular to its surface, it also includes a movable pressing plate 13, the movable pressing plate has an insertion hole 14 for inserting the fastening column, and there is an outer thread 15 around the fastening column, this outer thread is the outer thread of the fastening column, and a fastening nut 16 is installed on the outer thread of the fastening column. The top of the fixed liner and the bottom of the movable pressing plate are the parts where the raw material disc is placed flat and the raw material disc is pressed. The fixed liner, the fastening column, the movable pressing plate and the fastening nut form a pressing assembly 1.

[0026] The present invention is configured such that the tipping paper to be punched is processed on the tipping paper laser punching pre-processing device by placing the entire tray of tipping paper on the compressed portion of the raw material tray. Figure 1 3 is the station for placing the raw material tray flat. The movable pressure plate is pressed on the raw material tray and the fastening nut is tightened to put pressure on the raw material tray, causing the side of the tipping paper to shrink, that is, the width is reduced. Generally speaking, the reduced width is about 1% of the tipping paper width. This treatment is to cope with the stress deformation generated during punching, to improve the standardization of the laser holes and to improve the flatness of the punched parts of the tipping paper.

[0027] Furthermore, the surfaces of the fixed lining plate and the movable pressing plate have a plurality of evenly distributed small holes 17, and the diameter of the small holes is 3 to 5 mm.

[0028] The laser punching pretreatment device for tipping paper is configured in this way, which is beneficial for adjusting the humidity inside the entire tray of tipping paper when the tipping paper is processed.

[0029] Furthermore, the fastening columns include a central fastening column 121 in the middle and peripheral fastening columns 122 around the central fastening column, and the through holes include a central through hole in the middle and peripheral through holes around the central through hole.

[0031] Furthermore, it also includes a placement pad 2 for placing the pressing assembly, the placement pad includes a bottom pad 21 and an upper plate 22, the bottom pad and the upper plate are connected by a spring 23, and a vibration device 24 is installed on the upper plate; the upper plate has convex ridges 25 around it to limit the pressing assembly from running out.

[0032] The tipping paper laser punching pretreatment device is configured in this way, and can also achieve the purpose of achieving a better effect in dealing with stress generated during punching.

[0033] The upper plate is provided with convex ridges around which the pressing assembly is restricted from running out, so as to prevent the entire pressing assembly from running out of the upper plate when the paper is being processed.

[0034] In one embodiment, the vibration device generates an amplitude of 1-2 mm and a frequency of 10-15 Hz.

[0035] Furthermore, the present tipping paper laser perforation pretreatment device further comprises a humid chamber (illustrated in the figure), the temperature inside the humid chamber is 75-80%, the temperature inside the humid chamber is 25-30°C, and the interior of the humid chamber is a space for placing the pressing assembly.

[0037] The present invention is provided with a humidifying chamber. When pre-treating the tipping paper, the pressing assembly installed with the pre-treated tipping paper can be placed in the humidifying chamber for treatment. If necessary, a pad can be placed underneath to punch the obtained tipping paper, which can achieve a better punching effect.

[0038] The technical solution of the tipping paper laser drilling method of the present invention is achieved as follows: the tipping paper laser drilling method uses a laser drilling machine to perform laser drilling on the tipping paper. Before the tipping paper is punched, the tipping paper base paper is first pre-treated. The pre-treatment is a pressing treatment, that is, the side of the tipping paper is pressed in a direction parallel to the surface of the tipping paper, so that the side of the tipping paper base paper shrinks to cope with the stress and deformation during the punching of the tipping paper base paper.

[0039] Furthermore, the width of the pretreated tipping paper is reduced by 1 to 1.2%.

[0040] Furthermore, the temperature of the pre-treated tipping paper is 25-30°C.

[0041] Furthermore, the humidity of the pre-treated tipping paper is 2 to 2.5%.

[0042] The humidity of 2 to 2.5% means that the mass of the binding paper is reduced by 2 to 2.5% due to evaporation of water after the binding paper is fully dried.

[0043] Furthermore, while the tipping paper base paper is being pre-treated, the tipping paper is also being treated by vibration.

[0044] Furthermore, the vibration treatment is performed with an amplitude of 1-2 mm, a frequency of 10-15 Hz, and a time of 30-50 minutes.
