Problems solved by technology

However, this die-cutting knife is a plane knife, that is, a die-cutting knife edge with a pattern shape is set on a plane or a round roller, and its purpose is to cut the paper into the required pattern. a lot of material waste
And because the film material is thinner than paper and has better toughness and flexibility, the use of a flat die-cutter may cause some films to be unable to be cut, so the existing die-cutter is not suitable for film molding processing

Embodiment 1

[0057] In order to overcome the above-mentioned shortcoming in the prior art, the present embodiment provides a kind of novel packaging film pull wire 1, such as Figure 2A As shown, the structure is a strip structure with a certain width, and the two sides 11 and 12 of the pull wire are in the shape of a periodically changing sinusoidal curve, and the shapes 11 and 12 on both sides correspond to the positions completely. When packaging, such as Figure 2B As shown, the pull wire 1 is embedded between the packaging film 2 and the packaging box 3 . During use, pull up the pull wire 1 along the direction perpendicular to the packaging film 2 by hand, as shown by the hollow arrow in the figure. Under the action of the pulling force, the shearing force F generated by the sides 11 and 12 of the pulling wire 1 on the film packaging is much larger than that of the existing linear pulling wire. The film package 2 can be easily pulled apart along the pull wire 1 , and the cutout of t...

Embodiment 2

[0060] Such as image 3 As shown, one side 11 of the pull wire 1 changes in a periodically changing sinusoidal curve, while the other side 12 still retains the existing straight-line structure. During use, the opening of the film packaging is in a straight line and changes in a sinusoidal curve. It has a pull cord and an opening structure different from that of Embodiment 1, and has unique characteristics on the packaging.

Embodiment 3

[0062] The shape of the two sides 11, 12 of the backguy 1 of the present embodiment is the same as that of the embodiment 1, as Figure 4 As shown, the main difference is that the phase difference between the upper and lower sides 11 and 12 is half a period. When in use, the opening of the film package is also similar to that of Example 1, which can be used as an indication of cigarettes of comparable quality.

Abstract

The invention relates to the field of packaging film opening structure, and aims to overcome the deficiencies in the prior art, and provide a packaging film pulling wire structure, method and equipment with reasonable structure, unique appearance and anti-counterfeiting function. The present invention has a strip structure with a certain width as the existing pull wire, and its special feature is that at least one side of the pull wire is a periodically changing irregular side. The production method is to use a round knife provided with multiple groups of parallel shaped blades to rotate and cut on a whole piece of packaging film, and process the whole piece of packaging film into a plurality of pull wires with at least one side of which is a periodically changing irregular shape. Its equipment mainly includes a round knife and a support roller with multiple sets of side-by-side molding blades. The circular knife and the support roller are installed in parallel in the axial direction and rotate to cut the film passing between them. The knife edge at least partially enters the backup roll.

Description

technical field [0001] The invention relates to the field of opening structures of packaging films, more specifically to a manufacturing method and equipment for pulling wire structures for unsealing openings of cigarette packages or articles packaged in packaging films. technical background [0002] The opening structure of the existing cigarette packaging film is to set a circle of backguy at the position of the opening of the cigarette case. When the cigarette needs to be unpacked, only the end of the backguy needs to be pulled, pulled along the direction of the backguy, and rotated around the cigarette case once. The cigarette packaging film can be divided into two parts to open the packaging structure. This structure is simple and convenient to use, so it has been used until now. However, with the further development of the packaging industry, this structure also has some shortcomings and shortcomings. The side of the existing pull wire structure is straight, so the s...
