Embodiment 1

[0045] Get 10 pieces of test samples that the same kind of cigarette packaging glue-cigarette carton paper matches, use the fixture of the present invention, carry out the upper machine test of anti-45 ° and 120 ° (each doing 5 pieces) peel strength respectively, its test data The average values ​​are 5.836kN / m and 7.208kN / m respectively. Through the data analysis of the above peel strength, the strength of this kind of cigarette packaging glue meets the mechanical properties and the national standard or industry standard, and then the technicians used this glue in the actual cigarette production and packaging process, and found no displacement of the lap joint, Quality problems such as cracking, warping, and air leakage show that this method can well characterize the actual strength of the non-90° peeling force damage on the adhesive surface after the use of water-based adhesive for cigarettes in the cigarette production process.

Embodiment 2

[0047] Get 10 pieces of test specimens that are matched by the same kind of lapping glue-cigarette paper, use fixture of the present invention, carry out the on-machine test of anti-75 ° and 108 ° (each doing 5 pieces) peel strength respectively, the average value of its test data They are 2.957kN / m and 5.385kN / m respectively. Through the data analysis of the above peel strength, the strength of this lapping glue meets the mechanical properties and the national standard or industry standard, and then the technicians used this glue in the actual cigarette production and packaging process, and did not find any lap joint displacement, Quality problems such as cracking, warping, and air leakage show that this method can well characterize the actual strength of the non-90° peeling force damage on the adhesive surface after the use of water-based adhesive for cigarettes in the cigarette production process.

Embodiment 3

[0049] 10 pieces of test samples matched by the same mouthpiece glue-tipping paper, use the fixture of the present invention to carry out the upper-machine test of the peel strength of 30 ° and 135 ° (each doing 5 pieces) respectively, and the average value of the test data They are 5.094kN / m and 6.243kN / m respectively. Through the data analysis of the above peel strength, the strength of this kind of mouth glue meets the mechanical properties and the national standard or industry standard, and then the technicians used this glue in the actual cigarette production and packaging process, and found no displacement of the lap joint, Quality problems such as cracking, warping, and air leakage show that this method can well characterize the actual strength of the non-90° peeling force damage on the adhesive surface after the use of water-based adhesive for cigarettes in the cigarette production process.

Abstract

The invention provides a method and clamp for testing the anti-stripping strength of a cigarette water-soluble adhesive on cigarette paper. The clamp comprises a straight line mechanism sliding through a linear bearing and an angle adjusting support mounted on the straight line mechanism. A sample strip supporting plate is hinged to the angle adjusting support and can forwardly and reversely rotate by 360 degrees on the angle adjusting support around a hinged point. The angle adjusting support is provided with a locking mechanism used for fixing the position of the sample strip supporting plate, and the sample strip supporting plate is provided with a clamping groove which is matched with testing sample strips in thickness and used for fixing the testing sample strips. According to the method and clamp, a good supplementing and perfecting effect is achieved for the limitation that only 90-degree and 180-degree anti-stripping strength of the adhesive can be measured, and particularly the cigarette production process can be well represented; after the water-soluble adhesive is used, an adhesive connecting face can be suffered by the actual strength of a non-90-degree stripping forcedestroy effect usually, and the important significance to improving technology progress is achieved in the cigarette industry is achieved.

Description

technical field [0001] The invention relates to a method and a fixture for testing the anti-peeling strength of cigarette water-based glue on cigarette paper. Background technique [0002] The peel strength of the adhesive refers to the peel strength when the stress is concentrated on the bonded surface of the bonded test piece and is peeled away from the edge line. Generally, when rigid materials (such as metal, wood, glass, etc.) are glued to flexible materials such as paper, rubber, fabric, etc., the peel strength needs to be measured. At present, there are three test methods for the peel strength of adhesives at home and abroad: 90° peel resistance, 180° peel resistance, and T-shaped peel resistance. Among them, 90° peel resistance and 180° peel resistance are suitable for testing between rigid materials and flexible materials. , while "T" peel is only used for testing between two flexible materials. There are corresponding national standards or industry standards for ...
