Description
Technical Field
The invention relates to a gluing system, in particular to a cigarette tipping paper gluing system which enables glue to be conveyed under a totally-enclosed condition, forms a preset glue pattern on cigarette tipping paper in a spraying mode through a nozzle, and timely cleans and seals a gluing nozzle in the stopping process of gluing operation to ensure efficient and reliable operation of the gluing process, and belongs to the technical field of tobacco processing.
Background
In the production process of filter-tipped cigarettes, a filter tip and a cigarette strip are wrapped and connected into a long cigarette by using a tipping paper sheet coated with glue, so that the gluing of the tipping paper is a very important process in the tipping process of the filter-tipped cigarettes, and the quality of the gluing has an important influence on the quality of a final cigarette product. For example, poor gluing of tipping paper easily causes the product defects such as cigarette dilution quality defect, glue leakage pollution, influence on twisting and splicing, easy cigarette air leakage, tipping paper edge warping, wrinkles, substandard ventilation rate and the like. Once the gluing defect occurs, the cigarette making machine will remove the paper sheets with the gluing defect and the matched cigarette rods, filter tips and the like, thereby causing a great deal of material waste. The tipping paper sizing process is typically as follows: the paper tape after being uncoiled is rubberized according to a predetermined glue pattern through a nozzle of the rubberizing part so as to meet the requirements of the cigarette production process, and meanwhile, the rubberizing part is cleaned in time so as to prevent residual glue from blocking the nozzle of the rubberizing part after being dried, and further influence the subsequent rubberizing quality.
In the gluing process of the existing tipping paper, gluing is mostly carried out in a spraying mode, namely: the glue is sprayed on the gluing surface of the tipping paper after the pressure glue is conveyed to a multi-path rotary on-off valve through a pipeline and then is sent to a distributor through the multi-path rotary on-off valve. The multi-path rotary on-off valve is characterized in that a plurality of raised teeth or bosses are arranged at different positions on the outer circumferential surface of a rotor of the multi-path rotary on-off valve, and when the rotor rotates, a distributor glue supply pipeline corresponding to the rotor is opened and closed successively through the teeth or bosses at the different positions, so that a glue area and a glue-free area are formed on the glue applying surface of the tipping paper, and a preset glue pattern is formed. The prior art has the following defects: when glue passes through the rotor rotating at a high speed, vortex and stirring can be generated, when the glue reaches the inlet end of the distributor, the pressure of the glue is uncontrollable, the thickness of the glue sprayed by the distributor is inconsistent, the coaxiality of the rotor and the stator is difficult to guarantee due to the restriction of part processing and assembling precision, and under the condition that the requirement on the fit clearance between the rotor and the stator is extremely small, the rotor rotating at a high speed and the stator can generate friction, and further, due to the dynamic sealing influence of the side of the driving shaft, a large amount of heat can be generated by a gluing part, so that the water of the residual glue on a nozzle is easy to evaporate and condense, and a gluing.
On the other hand, in the conventional glue nozzle cleaning, the glue nozzle is placed in a lifting water tank with a certain amount of water below the glue nozzle in a rotating and moving mode, and a nozzle of the glue nozzle is immersed downwards in the water and then cleaned by a brush. When the nozzle of the nozzle faces downwards, the rotor and the stator of the rotary distribution valve are limited by clearance fit, and the density of the glue is greater than that of water, so that the glue in the pipeline and the valve can automatically flow into the water under the action of gravity, the glue is wasted, and the water in the water tank is polluted by the glue to influence the cleaning effect. Therefore, there is a need for improvements in the prior art.
