Paper packaging has a long and extensive history of use among packaging materials. Due to its readily available materials, light weight, ease of printing, ease of design and molding, and low cost, it is widely used for both sales and transportation packaging.

[0003] Paper packaging boxes can be divided into corrugated boxes and single-layer cardboard boxes according to the materials used, and are available in various specifications and models. Common paper packaging box structures include three-layer and five-layer structures, while seven-layer structures are less commonly used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are made of tea board paper and kraft paper, and the core paper is made of corrugated paper.

[0004] When producing paper packaging boxes, cardboard needs to be cut. A cutting device is used for the cutting of cardboard. Most traditional cutting devices are designed and used with a single cutter structure. Therefore, in a single cutting operation, only one side of the cardboard can be cut. The cutting efficiency is low, which affects the overall production speed of the packaging boxes. Therefore, the utility model proposes a cardboard cutting device for packaging box production and processing, which can cut cardboard on both sides. Utility Model Content

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] See also Figure 1-4The utility model provides an embodiment: a cardboard cutting device for packaging box production and processing, comprising a cabinet 1, a workbench 2 is provided on the upper surface of the cabinet 1, upper columns 3 are fixedly installed on both sides of the upper surface of the workbench 2 by welding, a supporting cross plate 4 is fixedly installed between the tops of the two upper columns 3, a cutting frame 7 is provided below the supporting cross plate 4, and bearing seats are fixedly installed at both ends of the lower surface of the cutting frame 7, a threaded screw 8 is rotatably connected between the two bearing seats, the threaded screw 8 is a forward and reverse screw, and the outer surfaces of both ends of the threaded screw 8 are threadedly connected to a sliding seat 10, in order to provide rotational power for the rotation of the threaded screw 8, one end of the threaded screw 8 is fixedly connected to the output shaft of the pitch-adjustable motor 14;

[0025] In this structural design, the adjustable pitch motor 14 can drive the screw rod 8 to rotate forward or reverse through its output shaft. Since the screw rod 8 is a forward and reverse screw, when the screw rod 8 rotates, the two sliding seats 10 threadedly connected thereto will move relative to each other, that is, move away from or closer to each other.

[0026] The lower surfaces of the two sliding seats 10 are fixedly mounted with connecting columns 11, and the bottom ends of the connecting columns 11 are fixedly mounted with a tool holder 12. The tool holder 12 is perpendicular to the cutting frame 7. A cutting knife 13 is fixedly mounted inside the tool holder 12. The setting of the cutting knife 13 can meet the needs of cutting cardboard.

[0027] In order to drive the cutting blade 13 to descend for cutting and ascend for reset, a hydraulic cylinder 5 is fixedly installed at the center of the upper surface of the supporting horizontal plate 4 by bolts. The output end of the hydraulic cylinder 5 is telescopically connected to a hydraulic rod 6, and the bottom end of the hydraulic rod 6 is fixedly connected to the cutting frame 7.

[0028] This structural design can drive the hydraulic rod 6 to extend and retract through the hydraulic cylinder 5. When the hydraulic rod 6 is extended and retracted, it will drive the cutting knife 13 at the bottom to rise and fall, thereby completing the cutting and resetting work of the cutting knife 13.

[0029] In this embodiment, in order to improve the displacement guidance of the sliding seat 10, guide rails 9 are fixedly installed on both sides of the threaded screw 8 and located on the lower surface of the cutting frame 7. The two sliding seats 10 are both slidably connected to the guide rails 9.

[0030] In this embodiment, in order to provide a certain degree of upward and downward displacement guidance for the rising and falling of the cutting frame 7, guide rods 15 are fixedly installed on both sides of the upper surface of the cutting frame 7. The top end of the guide rod 15 passes through the supporting cross plate 4, and the guide rod 15 is slidably connected to the supporting cross plate 4. By providing the guide rod 15, the cutting frame 7 can slide up and down when it rises or falls, so that the guide rod 15 can provide a displacement guide for the up and down displacement, avoid displacement deviation, and improve displacement accuracy.

[0031] In this embodiment, a square limiting strip 16 is fixedly installed on the upper surface of the workbench 2. When in use, a cardboard adapted to the cutting size of the present invention is placed into the square limiting strip 16, so that the cardboard can be limited and blocked on all sides by the provided limiting strip 16 to prevent movement during cutting.

[0032] In this embodiment, an inspection door 17 is hingedly connected to the outer surface of the cabinet 1 via a hinge, and a handle is installed on the inspection door 17. Support legs 18 are fixedly installed at the four corners of the lower surface of the cabinet 1 via bolts.

[0033] Working principle: When the utility model is used, the cardboard of the cutting size adapted to the utility model is placed into the square limit strip 16, so that the limit strip 16 can limit and block the four sides of the cardboard to prevent cutting and movement;

[0034] After the cardboard is placed on the workbench 2, the hydraulic cylinder 5 can be put into operation. When the hydraulic cylinder 5 is working, it drives the hydraulic rod 6 to extend. When the hydraulic rod 6 is extended, it drives the two cutting knives 13 at the bottom to descend. In this way, the two cutting knives 13 can complete the double-sided cutting of the cardboard.

[0035] According to the above description, the utility model adopts a double-cutter structural design, which can complete the double-sided cutting of the cardboard in a single cutting operation. The cutting efficiency is twice as efficient as that of the existing single-cutter structure. The overall cutting efficiency of the cardboard is greatly improved, the production speed of the packaging box cardboard is increased, and the practicality is better.

[0036] At the same time, the utility model is provided with a pitch-adjustable motor 14, which can drive the threaded screw 8 to rotate forward or reverse through its output shaft. Since the threaded screw 8 is a forward and reverse screw, when the threaded screw 8 rotates, the two sliding seats 10 threadedly connected thereto will move relative to each other, that is, move away from or closer to each other;

[0037] In this way, the relative movement of the two sliding seats 10 can drive the cutting blade 13 at the bottom end to move relative to each other, so that the distance between the two cutting blades 13 can be effectively adjusted. In actual use, by adjusting the distance between the two cutting blades 13, the cutting size of the cutting blade 13 can be adjusted, so that it can be suitable for cutting cardboards of different sizes for processing and use, thereby increasing the size cutting range of the cardboard and reducing the limitation of use. It has better use effect, a wider range of application of cutting size, strong practicality, and the overall device is simple, with low manufacturing and subsequent maintenance costs, and is suitable for popularization and use.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
