Problems solved by technology

In the actual production process, due to the fast production speed of the cigarette making machine and the characteristics of easy fouling of the glue application device, the tipping paper tends to be coated with glue beyond the glued area during the glue application and bonding process, resulting in the expansion of the glued area at the end of the filter rod , so that the glue-free area of ​​the tipping paper is bonded to the highly air-permeable forming paper of the filter rod. This situation seriously affects the ventilation rate of the cigarette, resulting in poor taste of the cigarette, which is regarded as a substandard product
The common detection methods of glued area and non-adhesive area are: the quality inspectors regularly take out the finished cigarettes, and then tear them by hand or cut them with scissors and observe the tipping paper between the glued area and the non-adhesive area of ​​the adhesive area. According to the situation of the distribution, using the experience value to judge whether the non-adhesive area at the end of the filter rod of this batch of cigarettes is qualified, the requirements for the inspection level of the quality inspection personnel are relatively high, and the accuracy of human judgment is affected by subjective consciousness, and the detection efficiency is low. Human consciousness is strong, reliability is poor
In the actual production process, the unqualified quality of the non-adhesive area of ​​the filter rod end has a high online rework rate, and the rated production speed of the cigarette machine is 7000 pieces per minute. Unqualified products in the non-adhesive area will lead to a substantial increase in cigarette production costs

Embodiment 1

[0074] like Figure 1-Figure 2 As shown in the figure, a detection device for the glue-free area of ​​a cigarette filter rod disclosed in this embodiment is mainly used to detect the suction resistance of the filter rod. There is a through hole to improve the user's suction taste, and the area of ​​the through hole is set as a glue-free area. By detecting the suction resistance of the filter rod, it is judged whether there is overflow of glue in the glue-free area, which blocks the through hole and causes the ventilation to be unsmooth. Specifically, the device for detecting the glue-free area of ​​a cigarette filter includes a cigarette seal and clamping assembly 1, which is used to clamp the cigarette body, and mainly acts on the filter rod of the cigarette and the cigarette. The sealing and clamping assembly 1 can form a sealing cavity for accommodating at least the filter rod in the clamping state. It should be noted that, since the cigarette includes a combustible sectio...

Embodiment 2

[0098] like Figure 19 As shown in the figure, this embodiment discloses a method for detecting the glue-free area of ​​a cigarette filter rod, using the device for detecting the glue-free area of ​​a cigarette filter rod as disclosed in Embodiment 1, including the following steps:

[0099] S1 presets the negative pressure detection value range D1-D2 of the first pressure detection device 4 when there is no glue overflowing in the glue-free area of ​​the sample cigarette filter rod;

[0100] In order to compare the information obtained by measuring the cigarettes to be detected with the information of the original cigarettes without glue overflow, first obtain the data of the first pressure detection device 4 during vacuuming according to the suction resistance of the original cigarettes without glue overflow, and use this as the data. target data. Since different batches of cigarettes are slightly different due to different environments and moisture content of cigarette mate...

Abstract

The invention discloses a device for detecting the glue-free area of ​​a cigarette filter rod, comprising a cigarette seal and clamping assembly, which is provided with a cigarette positioning groove for positioning the cigarette, and the cigarette sealing and clamping assembly can pass The cigarette positioning groove forms a sealing cavity for holding the cigarette, the sealing cavity is provided with a positive pressure air hole corresponding to the shaft end face of the cigarette filter rod, the positive pressure air hole is installed with a positive pressure pipe, and the positive pressure pipe is provided with a No. 1 to control the opening and closing of the pipeline. A switch, a first pressure detection device is arranged between the positive pressure air hole and the first switch, the sealing cavity is provided with a negative pressure air hole corresponding to the glue-free area of ​​the cigarette filter rod, the negative pressure air hole is installed with a negative pressure pipe, and the negative pressure pipe is provided with The vacuum generator is provided with a second pressure detection device between the negative pressure air hole and the vacuum generator. The invention also discloses a method for detecting the glue-free area of ​​a cigarette filter rod. The invention ensures the stability of the glue-free area of ​​the cigarette filter rod through the negative pressure process detection data collected in each batch, and can improve the batch sampling efficiency of the glue-free area of ​​the cigarette filter tip.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a detection device and a detection method for a glue-free area of ​​a cigarette filter rod. Background technique [0002] The cigarette (the ignitable part) and the filter rod are bonded and wrapped by the tipping paper with glue applied online to become the finished cigarette. The tipping paper is pre-drilled with two rows of 0.1mm diameter ventilation holes by laser. After wrapping the cigarettes and filter rods, the small round holes are arranged at a distance of 17mm from the suction end of the filter rod. The distance between the two rows of round holes is 5mm. There are 12 evenly distributed around the circumference. This perforated area is not smeared with glue during the cigarette rolling process, and the tipping paper is not bonded to the filter rod's highly breathable forming paper, which is called the glue-free area; other areas are coated with glue, and the tipping ...
