Any characteristic disclosed in the present specification, claims, Abstract and Figures can be replaced by other equivalent characteristics or characteristics with similar objectives, purposes and/or functions, unless specified otherwise.

[0037] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the following will be illustrated in detail in combination with the embodiments to facilitate the understanding of persons skilled in the art.

[0038] FIGS. 1 and 2 are the schematic view of the upper cover 1 of a device for cigarette tipping paper anti-adhesion test. The inner surface of the upper cover includes a plurality of upper cover semi-cylinders 11 with the same radius, closely configured in parallel. Each of the upper cover semi-cylinders 11 has a cross-section with a bow (e.g., semi-circular) shape.

[0039] As is shown in FIG. 3, a box 2 has a plurality of holes 211 configured on the box upper surface 21, connected with the inner cavity of the box 2. The side wall of the box 2 has an opening 22. The opening 22 can be connected to an external hot air device. The opening 22 can also be connected to an external damp and hot air device. Hot air or damp and hot air can be introduced into the inner cavity of the box through the opening 22. The hot air or damp and hot air can also pass through the plurality of the holes 211 to the cigarette tipping paper to be tested. As shown in FIG. 3, the box upper surface 21 is flat.

[0040] As is shown in FIG. 4, preferably, the box upper surface 21 has a plurality of box semi-cylinders 23 with the same radius, closely configured in parallel. The box semi-cylinders 23 may have the same radius as the upper cover semi-cylinder 11 and be arranged in the same axial direction. The box semi-cylinders 23 may have the same radius as the upper cover semi-cylinders 11 as well as the cigarette. Furthermore, the box semi-cylinders 23 may be configured so that the cylinder surface of each box semi-cylinder 23 is tangent to the cylinder surface of each corresponding upper cover semi-cylinder 11 in order to simulate extrusion between cigarettes.

[0041] A method for an anti-adhesion test of cigarette tipping paper using the device includes the following steps: spread two pieces of cigarette tipping paper 3 such that the printing surfaces thereof face each other on the box upper surface 21, cover the upper cover 1, then place a weight on the upper surface of the upper cover and record the value of the weight. Preferably, introduce hot air at a predetermined temperature (e.g., in the range of 35-150 ° C., but not limited to this range) into the box inner cavity 2 through the opening 22 and record the temperature (e.g., in the box inner cavity 2). After a certain period of time (e.g., 10-180 minutes), remove the two pieces of cigarette tipping paper 3, and test the adhesion force when separating the two pieces of cigarette tipping paper 3 to obtain anti-adhesion data of the cigarette tipping paper.

[0042] In the case that damp and hot air at the predetermined temperature (e.g., in the ranges of 50-100% relative humidity and 35-150 ° C., but not limited to these ranges) is introduced, the test may provide anti-adhesion data of two pieces of wet or damp (e.g., water-containing) cigarette tipping paper, as well as anti-adhesion data of two pieces of completely dry cigarette tipping paper (e.g., after dampening and drying). Damp and hot air at the predetermined temperature is introduced into the inner cavity of the box 2 through the opening 22. The damp and hot air dampens or wets the two pieces of cigarette tipping paper, and may also enter through a plurality of tiny holes 211 on the box upper surface 21. When two pieces of wet or damp cigarette tipping paper anti-adhesion data and two pieces of completely dry cigarette tipping paper anti-adhesion data are obtained, the actual conditions of cigarette products during packaging, transportation and storage can be better simulated.

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but the accompanying drawings and embodiments are not intended to limit the technical solutions of the present invention, and all changes or equivalent substitutions made based on the teachings of the present invention shall belong to the present invention's protection scope.

The maximum adhesion force of the two pieces of completely dry cigarette tipping paper is measured as 2.895N. The printing surface of the cigarette tipping paper is seriously adhered, and one piece of the cigarette tipping paper is torn and broken during separation.
