Description

Method for measuring solidification rate of lap adhesive of cigarette paper and application thereof Technical Field The invention belongs to the technical field of tobacco processing, and particularly relates to a method for measuring the curing rate of lap adhesive of cigarette paper and application thereof. Background In addition to the main raw materials, the cigarettes also need to be studied for the adhesive used by the cigarettes. The lap adhesive is a special adhesive for cigarettes, which is applied to the process of manufacturing cigarettes and used for bonding cigarette paper, and has very important effect in the process of forming cigarettes. The high-speed machine for cigarettes is introduced, so that the production efficiency of cigarettes is greatly improved, the speed of the cigarettes is improved, the requirements on cigarette adhesive are higher and higher, and the cigarette lap adhesive is required to have good initial viscosity and quick-drying property. The curing temperature of the currently used lap adhesive is generally 220-260 ℃, and the higher the working temperature of a soldering iron of a cigarette making machine is, the more easily the problems of deformation of the contact surface of the soldering iron and cigarette paper, accelerated performance attenuation of the soldering iron and the like are generated, so that a great number of adverse effects are brought to equipment maintenance and cigarette product quality. In addition, a certain amount of essence and spice can be added into the cut tobacco of the cigarette in the preparation process for flavoring, the essence and spice in the cut tobacco can be worn out to a certain extent due to the high temperature of the soldering iron, and part of water in the cut tobacco can be evaporated, so that the smoking sense of the cigarette and the quality stability of the cigarette are affected. Therefore, the drying speed is improved, and the reduction of the curing time of the lap adhesive has an important influence on improving the quality of cigarette products. In addition, if the bonding adhesive can effectively shorten the bonding adhesive curing time on the premise of ensuring the adhesive effect, the service life of the soldering iron can also be effectively prolonged, and the production cost is reduced. However, in the prior art, the method for measuring the curing rate of the lap adhesive is deficient, lacks a set of accurate and standard measuring flow, and cannot provide reliable data support for formula optimization of the lap adhesive and adjustment of the cigarette production process. CN222913651U discloses a glue solidification rate detection device, the on-line screen storage device comprises a base, base one end upside fixedly connected with places the platform, and the base is kept away from the one end fixedly connected with adjusting part who places the platform, adjusting part upper end fixedly connected with sampling component, and sampling component one end fixedly connected with rotating assembly, the one end outside fixedly connected with who places the platform is kept away from to the base is cleaned the subassembly, adjusting part includes the base and keeps away from the first motor of placing platform one end outside fixedly connected with, and first motor output shaft fixedly connected with threaded rod, the one end swivelling joint that the first motor was kept away from to the threaded rod is in the base, and threaded rod middle-end outside meshing has the screw block, and clean subassembly upper end fixedly connected with storage module, clean subassembly lower extreme fixedly connected with collection subassembly, make detection device can accomplish the sample work automatically when using, the detection mode is simple and convenient, simultaneously after detecting, still can clean the sampling structure outside.
