Automatic gluing type sealing device for ventilation hole of cigarette filter

Abstract

The invention discloses an automatic gluing type sealing device for a ventilation hole of a cigarette filter which is characterized in that a sliding rod is arranged on a supporting rod, the sliding rod is fixedly connected with a gluing sleeve, a glue injection port is formed in the top end of the gluing sleeve, a mucilage glue cavity is formed in the gluing sleeve, a blind path is formed in thebottom end of the gluing sleeve, and a liquid outlet is formed in the side wall face of the blind path; a rotary sleeve is assembled on a base and internally inserted with a fixed cylinder. The cylindrical wall of the fixed cylinder is provided with air inlet hole and an air outlet hole, a rubber tube is assembled inside the cylindrical wall. An annular chamber is arranged in the rotary sleeve inan opened manner. An air inlet and an air inlet and outlet are opened at the bottom of the rotary sleeve. An air outlet is opened at the upper part of the rotary sleeve. The air inlet and outlet are connected with the air outlet in the side of the annular chamber. Viscose can be uniformly coated at the vent hole of the filter tip through the viscose liquid outlet, so that the problems that bubblesare easily generated between an adhesive tape and the filter tip in an adhesive tape winding and sealing manner, the adhesive tape is easily unglued, the sealing effect is influenced in a smoke release substance measuring process and the like are solved; a vent hole of the cigarette filter can be quickly sealed by uniformly coating liquid glue at the vent hole of the filter, the operation is simple, the sealing effect is good, and the character of a cigarette is not changed.

Description

technical field [0001] The invention relates to a device for closing ventilation holes of cigarette filters. Background technique [0002] With the increasing emphasis on tobacco and health in countries around the world, the World Health Organization (WHO) has proposed in recent years to use the Canadian deep smoking mode to measure smoke emissions. It is stipulated, and at the same time, it is required to carry out the measurement under the condition that the ventilation hole of the cigarette filter is completely closed, and the closed filter ventilation hole is a necessary means to carry out the study of the deep smoking mode. [0003] At present, there are mainly two ways to close the filter vent hole: special cigarette holder and tape winding. The special cigarette holder sealing method is not suitable for popularization because it is expensive and must be used in conjunction with the smoking machine; the sealing method of tape winding is divided into two methods: manua...

AI Technical Summary

Problems solved by technology

The special cigarette holder sealing method is not suitable for popularization because it is expensive and must be used in conjunction with the smoking machine; the sealing method of tape winding is divided into two methods: manual sealing and mechanical sealing. The effect is poor. Although the mechanical tape winding and sealing method avoids the disadvantages of the manual tape winding and sealing method, the mechanical tape winding and sealing method itself changes the properties of the cigarette because the tape is wound on the cigarette filter, and the tape and the filter Air bubbles are likely to be generated between them, and the adhesive tape is likely to be glued. When a cigarette is inserted into a standard cigarette holder, it is easy to cause friction between the adhesive tape and the labyrinth ring of the cigarette holder, causing part of the adhesive tape to separate from the cigarette filter, affecting the cigarette filter. The sealing effect of the mouth ventilation hole, thus affecting the stability of the test results of the smoke emission
