Abstract
Description
Technical Field
[0001] This invention belongs to the field of packaging machine technology, specifically relating to a ZB45 packaging machine aluminum foil half-tear-out cutting device. Background Technology
[0002] The ZB45 packaging machine is used for hard-pack packaging of cigarettes. During operation, cigarettes are conveyed in a conveyor box, and aluminum foil is conveyed via a conveyor shaft, cut by a cutting blade, and then wrapped around the cigarettes. In the ZB45 packaging machine, existing machines have both fixed and adjustable cutters for cutting the aluminum foil, and a circular dotted-line cutter on the upper part of the machine. The existing cutter layout results in a circular cutting dot that extends half the length of the aluminum foil, causing the inner liner to tear in one straight line. This cutter structure creates a large tear in the inner liner, allowing impurities in the air to easily seep into the cigarette box through the dotted line, and the aroma of the tobacco also dissipates into the air, significantly affecting product quality. Therefore, improvements are necessary. Summary of the Invention
[0003] The technical problem solved by this invention is to provide a half-tear cutting device for aluminum foil paper in a ZB45 packaging machine. This invention improves the cutting structure of the aluminum foil paper in the ZB45 packaging machine, while maintaining the original speed ratio and cutting phase, without changing the gearbox transmission structure. This changes the tearing of the inner lining paper of the cigarette box from a one-time straight tear to a single straight tear on the left half, reducing the tearing area by half. This achieves the effect of keeping the cigarette pack moist and fragrant without significantly modifying the equipment, thus improving product quality.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The ZB45 packaging machine's aluminum foil semi-tear-off cutting device includes a packaging machine body. A fixed cutting shaft and an adjustable cutting shaft are supported on the machine body. The fixed and adjustable cutting shafts are horizontally parallel to each other. The rotational speed ratio of the fixed and adjustable cutting shafts remains constant, i.e., the rotational speed of the fixed cutting shaft is twice that of the adjustable cutting shaft. The fixed cutting shaft is equipped with a fixed cutter and a fixed cross-cutting blade. The lengths of the fixed cutter and the fixed cross-cutting blade are fixed along the axial direction of the fixed cutting shaft. The fixed cross-cutting blade and the fixed cutter are installed at 180° on the circumferential surface of the fixed cutter shaft; the adjustable cutter shaft is provided with an adjustable cutter and an adjustable cross-cutting blade, the lengths of which are fixed along the axial direction of the adjustable cutter shaft on the circumferential surface of the adjustable cutter shaft, and the adjustable cutter and the adjustable cross-cutting blade are installed at 90°; the upper part of the packaging machine body is supported by a disc-shaped dotted line cutter shaft, and the end of the disc-shaped dotted line cutter shaft is provided with a disc-shaped dotted line cutter, which has a 90° blade.
[0006] Further defining the above scheme, as the fixed cutter shaft and the adjustable cutter shaft rotate according to the speed ratio, the fixed cutter and the adjustable cutter cut the edge line corresponding to the length of the aluminum foil. The fixed cross cutter and the adjustable cross cutter cut the dotted line a on the aluminum foil. The disc dotted line cutter cuts the dotted line b on the aluminum foil, and the dotted line b is 1 / 4 of the length of the aluminum foil. Correspondingly, the dotted line a is also perpendicularly connected to the dotted line b as the position of the fixed cross cutter and the adjustable cross cutter changes.
[0007] Further defining the above solution, the fixed cutter and the fixed cross-cutter are fixed to the fixed cutter shaft by screws, and the adjustable cutter and the adjustable cross-cutter are fixed to the adjustable cutter shaft by an adjustable structure.
[0008] Further defining the above solution, both the adjustable cutter and the adjustable cross-cutter are provided with multiple connecting holes, which are fixed to the adjustable cutter shaft by set screws. The connecting holes are elongated holes, and the set screws can slide within the connecting holes.
[0009] Advantages of this invention compared to existing technologies:
[0010] This solution improves the cutting structure of the aluminum foil paper in the ZB45 packaging machine by redesigning the cutter shaft structure of both the fixed and adjustable cutters. It adds two cutter positions: a fixed cross-cutting blade and an adjustable cross-cutting blade, maintaining the original speed ratio and cutting phase without altering the gearbox transmission structure. The cutting process shifts the original horizontal dotted line 'a' on the aluminum foil upwards. Simultaneously, the disc cutter on the packaging machine is improved, reducing the dotted line 'b' formed by the disc cutter to half its original size. This changes the tearing of the cigarette box liner from a single, straight tear to a tearing only on the left half, reducing the tear area. This minimizes the loss of moisture and aroma from the tobacco through the tear, achieving a certain level of moisture and aroma retention, and reducing the impact of opening time on product quality.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0017] Please see Figure 1-4 The embodiments of the present invention are described in detail below.
[0018] Example: ZB45 packaging machine aluminum foil half-tear cutting device, see reference. Figure 1 As shown, the packaging machine includes a body 1, on which a fixed cutter shaft 2 and an adjustable cutter shaft 5 are supported. The fixed cutter shaft 2 and the adjustable cutter shaft 5 are horizontally parallel to each other. The rotational speed ratio of the fixed cutter shaft 2 and the adjustable cutter shaft 5 remains constant, that is, the rotational speed of the fixed cutter shaft 2 is twice that of the adjustable cutter shaft 5. The fixed cutter shaft 2 is equipped with a fixed cutter 3 and a fixed cross-cutter 4. The lengths of the fixed cutter 3 and the fixed cross-cutter 4 are fixed along the axial direction of the fixed cutter shaft 2 and are fixed to the circumferential surface of the fixed cutter shaft 2. The fixed cross-cutter 4 and the fixed cutter 3 are installed at 180°. The adjustable cutter shaft 5 is equipped with an adjustable cutter 6 and an adjustable cross-cutter 7. The lengths of the adjustable cutter 6 and the adjustable cross-cutter 7 are fixed along the axial direction of the adjustable cutter shaft 5 and are fixed to the circumferential surface of the adjustable cutter shaft 5. The adjustable cutter 6 and the adjustable cross-cutter 7 are installed at 90°. The upper part of the packaging machine body 1 is supported by a disc dotted line cutter shaft 8, and the end of the disc dotted line cutter shaft 8 is provided with a disc dotted line cutter 9, which has a 90° blade.
[0019] As the fixed cutter shaft 2 and the adjustable cutter shaft 5 rotate according to the speed ratio, the fixed cutter 3 and the adjustable cutter 6 cut the edge lines of the aluminum foil 10, the fixed cross-cutter 4 and the adjustable cross-cutter 7 cut the dotted line a12 on the aluminum foil 10, and the disc dotted line cutter 9 cuts the dotted line b11 on the aluminum foil 10, reducing the dotted line b11 to half its original size. Correspondingly, the dotted line a12 also becomes perpendicular to the dotted line b11 as the positions of the fixed cross-cutter 4 and the adjustable cross-cutter 7 change.
[0020] The fixed cutter 3 and fixed cross-cutter 4 are fixed to the fixed cutter shaft 2 with screws, and the adjustable cutter 6 and adjustable cross-cutter 7 are fixed to the adjustable cutter shaft 5 through an adjustable structure. Specifically, the adjustable structure consists of multiple connecting holes on both the adjustable cutter 6 and the adjustable cross-cutter 7, which are fixed to the adjustable cutter shaft 5 with set screws. These connecting holes are elongated holes, allowing the screws to slide within them. When installing the adjustable cutter 6, to ensure effective high-speed cutting of aluminum foil, the three set screws are rotated to slowly move the adjustable cutter towards the fixed cutter until the optimal cutting effect is achieved. Finally, the three screws in the elongated holes on the cutter are tightened.
[0021] In this embodiment, the fixed cutter 3 and the adjustable cutter 6 maintain their original installation positions. The fixed cross cutter 4 is a newly added cutter, installed at 180° to the fixed cutter 3. The adjustable cross cutter 7 is installed perpendicular to the adjustable cutter 6. Figure 3 As shown, since the rotation speed of the fixed cutter 3 is twice that of the adjustable cutter 6, the fixed cutter 3 rotates twice to cut one sheet of aluminum foil. For each sheet of aluminum foil fed, the adjustable cutter 6 rotates one revolution. When the fixed cutter 3 rotates 720°, the adjustable cutter 6 rotates 360°, at which point the cutting of one sheet of aluminum foil is completed. When the fixed cross-cutter 4 rotates 180°, the adjustable cross-cutter 7 rotates 90°, and the adjustable cross-cutter 7 becomes tangent to the fixed cross-cutter 4, completing the cutting of the horizontal dotted line a12 of the aluminum foil.
[0022] The circular dotted-line cutter 9 has been changed from a 180° cutting edge to a 90° cutting edge, as shown below. Figure 4 As shown, the length of the dotted line b11 cut by the disc dotted line cutter 9 is changed from 1 / 2 of the original aluminum foil length to 1 / 4 of the aluminum foil length, as shown. Figure 2 As shown,
[0023] This invention improves the cutting structure of the aluminum foil paper in the ZB45 packaging machine by redesigning the cutter shaft structure of both the fixed and adjustable cutters. It adds two cutter positions: a fixed cross-cutting blade and an adjustable cross-cutting blade, maintaining the original speed ratio and cutting phase without altering the gearbox transmission structure. The cutting process shifts the original horizontal dotted line 'a' on the aluminum foil paper upwards. Simultaneously, the disc cutter on the packaging machine is improved, reducing the distance from the aluminum foil disc to the formed dotted line 'b' to half its original size. This changes the tearing of the cigarette box liner paper from a single, straight tear to a tearing only on the left half, reducing the tear area and minimizing the loss of aroma and moisture from the tobacco through the tear, thus ensuring product quality remains unaffected.
