Tipping paper heating rubbing connection method

Abstract

The invention discloses a tipping paper heating rubbing connection method, which comprises the following steps that: firstly, glue is coated on the surface of tipping paper, then, the tipping paper is heated through a heater, the heating temperature of the heater needs to be controlled at 180 DEG C to 200 DEG C, finally, the heated tipping paper is wound on a tipping paper drum wheel, in addition, the rubbing connection of the tipping paper on a filter tip filter rod is completed through the matching of the tipping paper drum wheel and a rubbing plate, the temperature of the tipping paper drum wheel is controlled between 50 DEG C and 70 DEG C, and the temperature of the rubbing plate is controlled between 90 DEG C and 100 DEG C. According to the method, the tipping paper is wound on the tipping paper drum wheel, the heater is used for prepositive heating, the heating temperature of the tipping paper drum wheel and the rubbing plate is reduced so that the heated temperature change of the filter tip filter rod is smaller, further, the absorption resistance change is correspondingly smaller, in addition, the temperature of the tipping paper drum wheel is lower, the damage to the tipping paper drum wheel can be avoided, the long-time reliable operation of the equipment is ensured, and the maintenance cost of the equipment is reduced.

Description

technical field [0001] The invention relates to a cigarette processing technology, in particular to a method for heating and rubbing tipping paper used on cigarette filter rods. Background technique [0002] Tipping paper is a material used as the outer packaging of cigarette filter rods. It is wrapped around the outer circumference of the filter rod. The tipping paper is usually wrapped around the filter rod by rubbing, that is, the tipping paper is wrapped around the water On the paper loosening drum, and set a washboard under the tipping paper drum, so that the filter rod of the cigarette is located between the tipping paper drum and the washboard, and the tipping paper drum can cut off the tipping paper, and then cooperate with the washboard Rely on friction to make the cut tipping paper wrapped on the filter rod, and the tipping paper needs to be coated with glue before being wound on the tipping paper drum, so as to facilitate the bonding of the tipping paper interface...

Problems solved by technology

[0003] In the rubbing process of tipping paper, in order to ensure that the glue on the tipping paper can be bonded, it is usually necessary to heat the tipping paper. At present, the heating of the tipping paper is mainly carried out by the tipping paper drum and the washboard. The working temperature of the wheel is about 150°C, and the working temperature of the washboard is about 260°C. This brings about a problem, that is, in the process of heating the tipping paper, the filter rod is also heated at the same time. After the filter rod is heated, its tow will be broken. deformation, the suction resistance of the filter rod will also change accordingly. It is detected that the suction resistance value of the filter rod will increase by 1.2mmWG every time the temperature of the filter rod rises by 1°C. The temperature of the filter stick will increase by 5-6°C, which will greatly increase the suction resistance of the filter stick and affect the quality of cigarettes.

[0004] In addition, the heating of the tipping paper drum is generally carried out by threading the heating wire inside it. When rubbing the tipping paper, the tipping paper drum must rotate at a high speed, so the heating wire must be transferred to the heating wire by a slip ring. The structure of the power supply and temperature controller is relatively complicated; when the tipping paper drum works at high temperature, the slip ring will be in the high temperature area for a long time, and its own contact resistance will also generate heat, which will inevitably cause the slip ring to contact Point oxidation will increase the contact resistance, which will affect the temperature measurement accuracy, increase the temperature fluctuation of the tipping paper drum, and even lose the normal working ability. In severe cases, the tipping paper drum will even be burned out.
