Description

Cigarette filter stick paper lap peeling force detection device and detection method Technical Field The invention relates to the technical field of filter stick detection equipment for cigarettes, in particular to a device and a method for detecting the lap peeling force of filter stick paper for cigarettes. Background The cigarette filter stick is an important component part of a cigarette product, and the structural integrity of the cigarette filter stick directly influences key physical indexes such as the smoking resistance, the ventilation rate and the like of the cigarette, and the final on-machine rolling quality. In the filter rod production process, the shaping paper is bonded to form a tubular structure through a lap joint, and the bonding effect of the lap joint is one of key factors for determining the stability of the filter rod structure. If the lap joint is not firmly adhered or has poor uniformity, the problems of deformation, glue spreading, even disassembly and the like of the filter stick are very easy to occur in the subsequent cigarette conveying, cutting and sucking processes, so that the product is unqualified or the operation efficiency of the machine is influenced. Therefore, the method accurately and reliably detects the bonding quality of the lap joint of the forming paper, and has important significance for process optimization and product quality control. At present, a stretching force measuring machine is generally adopted to measure the peeling force of a lap joint of the forming paper, namely, a filter rod sample is fixed on the stretching force measuring machine after being reversely split along the lap joint for a certain distance, the filter rod sample is gradually peeled along an adhesive interface through the stretching force measuring machine, and mechanical parameters in the stretching process are recorded, so that the firmness of the lap joint is evaluated. However, since the stretching force is directly applied to the molded paper sheet excellent in flexibility and the point of application is concentrated in a local area to be peeled, the subsequent paper tape portion which has not yet been peeled is subjected to uneven and unstable directional stress during the peeling. Such stress distribution is very prone to cause upward or downward warpage, wobble or jitter of the paper strap, and is unable to maintain a stable, continuous peeling path and stress. The unstable stripping state can interfere with the acquisition of real-time tension data, so that the fluctuation of a measured force value curve is severe, the repeatability and reproducibility of a test result are reduced, and secondly, stress concentration can be caused by swinging, so that the stripping behavior is not strictly carried out along an adhesive interface, and unexpected tearing of a paper substrate in a non-lap-joint area can be caused sometimes, thereby distorting the test result and failing to truly reflect the adhesive performance of the adhesive interface. In addition, in the actual production process, the gluing of the filter rod lap joint may have local defects, such as insufficient or complete missing of a certain small section of glue. Current detection methods typically only focus on the average value of the peel force, and such local defects are difficult to effectively identify in the calculation of the average value. However, the weak links are very easy to appear due to stress in the high-speed cigarette making process, so that the quality problems of foot warpage, buckling and the like of the formed paper are caused, and the product qualification rate is influenced. Disclosure of Invention The invention aims to provide a cigarette filter rod paper lap peel force detection device and a detection method, wherein the cigarette filter rod paper lap peel force detection device can inhibit the problems of swing, warping and the like of an unpeeled part of filter rod paper in a test process, improve the stability of a peel force measurement result, avoid accidental tearing of the filter rod paper, and can detect the firmness of a lap, detect the uniformity of lap adhesion and improve the qualification rate of the cigarette filter rod paper. To achieve the purpose, the invention adopts the following technical scheme: in one aspect, a device for detecting peel force of a filter rod paper lap for a cigarette is provided, comprising: The stretching mechanism comprises a tension detection assembly, a first clamping piece and a second clamping piece, wherein the first clamping piece and the second clamping piece are arranged at intervals along a first direction, the first clamping piece and the second clamping piece respectively clamp the end part of a first side face and the end part of a second side face of filter rod paper after being peeled off along a lap, the first clamping piece and the second clamping piece can be mutually far away so as to peel the filter rod paper, and the tension detectio
