Trademark paper slitting device

Technical Field

The invention relates to the technical field of tobacco packaging, in particular to a label paper slitting device.

Background

The rigid packet flip pack is a conventional packet pack format, as shown in fig. 1, the rigid packet flip pack being a single label 100 covering the packet. The existing hard box packaging machine sequentially carries out cigarette packet forming packaging through eight packaging wheels to form the hard box flip cigarette packet, and the forming process comprises the following steps: cigarettes in a cigarette warehouse are conveyed to a cigarette conveying wheel, a cigarette group is formed by the cigarette conveying wheel and then conveyed to an aluminum foil cigarette packet forming wheel for aluminum foil paper packaging, then conveyed to an inner frame paper input wheel for inner frame paper packaging through an aluminum foil cigarette packet transition wheel, then conveyed to a hard box cigarette packet forming wheel for trademark paper packaging, then conveyed to a hard box cigarette packet drying wheel for drying through a hard box cigarette packet transition wheel, and finally output through a hard box cigarette packet output wheel.

As shown in fig. 2 and 3, in the above-mentioned hard box packing machine, a transition bridge 01 is disposed between a hard box tobacco packet transition wheel and a hard box tobacco packet drying wheel, the transition bridge 01 includes a slot frame 011 and a slot cover 012 which are fixedly connected, a tobacco packet channel 010 which is vertically penetrated is formed between the slot frame 011 and the slot cover 012, the hard box tobacco packet transition wheel and the hard box tobacco packet drying wheel are respectively located below and above the transition bridge 01 tobacco packet channel 010, the tobacco packet 200 packaged by trademark paper is sent to the hard box tobacco packet transition wheel at the hard box tobacco packet forming wheel, and the tobacco packet 200 on the hard box tobacco packet transition wheel is sent to the hard box tobacco packet drying wheel through the tobacco packet channel 010 on the transition bridge 01. Because this kind of hard box flip cigarette packet is that single label paper 100 covers the cigarette packet, need not to carry out extra operation to the label paper after the packing of label paper is accomplished to hard box cigarette packet forming wheel, consequently, transition crane span structure 01 only plays the effect of transmission cigarette packet 200.

As the variety of the form of the package of the tobacco pouch increases with the development of the tobacco industry, a drawing type tobacco pouch as shown in fig. 4, which is provided with two brand papers, specifically, a first brand paper 101 and a second brand paper 102, which cover a pouch portion and a pouch cover portion of the tobacco pouch, respectively, is appeared, and the first brand paper 101 and the second brand paper 102 are connected through a drawing paper 103. Therefore, in the forming process, after the hard box cigarette packet forming wheel completes single Zhang Shangbiao paper packaging, the single trademark paper needs to be cut into two trademark papers to realize the drawing type packaging form. The existing hard box packing machine cannot realize the operation, so that the packing of the drawing type cigarette packet cannot be realized.

The first label 101 and the second label 102 after being cut are connected by the drawing paper 103 (as shown by 4-2 in fig. 4) to form a package form of the drawing type cigarette packet. The trademark paper cutting device of this embodiment has simple structure, simple to operate and adjusts convenient advantage to, the trademark paper cutting device of this embodiment can improve on the basis of current hard box packagine machine's transition crane span structure 01 and obtain, makes hard box packagine machine can satisfy the production demand that has the pull formula tobacco bale of two trademark paper packagings.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
