Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to a cutting device for corrugated paper production. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. Corrugated paper is often used for product packaging, is relatively environmentally friendly, and is widely used. In the production process of corrugated paper, corrugated paper needs to be cut into different sizes. In actual processing scenarios, the cutting precision is often low. There may be various factors that cause the low precision of corrugated paper after cutting, which may be due to cutting positioning, surface moisture, and uneven surface.

[0003] For example, a Chinese utility model patent with announcement number CN215282178U discloses a cutting device for processing corrugated cardboard. Although the solution fixes a clamping device on the upper side of the cutting bottom plate and then limits the corrugated cardboard to prevent the corrugated cardboard from shifting during cutting and avoiding cutting the corrugated cardboard crookedly, this clamping and positioning method requires that each time the corrugated cardboard is placed, the squeezing rod needs to be pulled outward first, and then the squeezing rod is released, and the squeezing and positioning of the cardboard on both sides is achieved by the spring. The operation is cumbersome and the feeding efficiency is low. In addition, there is a lack of a clamp on the other side of the cardboard, that is, only three-sided blocking and clamping is achieved. Such positioning may cause inaccurate positioning. Based on this, a cutting device for corrugated paper production is proposed. Utility Model Content

[0004] In order to solve the technical problems of corrugated paper processing, the utility model provides a cutting device for corrugated paper production.

[0005] The utility model is implemented by the following technical scheme: a cutting device for corrugated paper production, comprising a base and a fixed rod fixedly connected to the upper side of the base, a cutting table fixedly connected to the upper side of the base, a limiting plate fixedly connected to each side of the cutting table, a connecting rod slidably connected to one side of each limiting plate, a plurality of connecting rods are respectively fixedly connected to the upper sides of positioning plates, a cardboard cutting mechanism for performing one-time punching and cutting of corrugated cardboard is arranged at the upper end of the fixed rod, and a positioning plate driving mechanism for opening or closing the positioning plates is arranged on one side of the connecting rod.

[0006] As a further improvement of the above scheme, the cardboard cutting mechanism includes an electric cylinder fixedly connected to the upper end of the fixed rod, the output end of the electric cylinder is fixedly connected to a knife seat slidably connected to one side of the fixed rod, the lower side of the knife seat is fixedly connected to a pressing knife, and a cardboard shaping mechanism for pressing and flattening the surface of the cardboard is provided below the knife seat.

[0007] As a further improvement of the above scheme, the cardboard shaping mechanism includes multiple sliding rods slidably connected to one side of the knife seat, the lower ends of the multiple sliding rods are commonly fixedly connected to the knife mold, and the upper ends of the multiple sliding rods are provided with overload protection mechanisms to prevent the cardboard from being deformed due to excessive pressure.

[0008] As a further improvement of the above scheme, the overload protection mechanism includes a threaded rod fixedly connected to the upper ends of multiple sliding rods, and a threaded sleeve is threadedly sleeved on each of the multiple threaded rods, and a No. 1 spring is arranged between the multiple threaded sleeves and the tool holder.

[0009] As a further improvement of the above scheme, the positioning plate driving mechanism includes a tetrahedral boss that simultaneously abuts against one end of multiple connecting rods, and the lower side of the tetrahedral boss is fixedly connected to an upper push plate fixedly connected to the lower side of the tool holder, and the multiple connecting rods are provided with a self-centering positioning mechanism that automatically positions the positioning plate.

[0010] As a further improvement of the above solution, the self-centering positioning mechanism includes No. 2 springs respectively arranged between multiple connecting rods and the limit plates.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model cooperates with each other through the tetrahedral boss, connecting rod, No. 2 spring, positioning plate and cutting table. When the electric cylinder presses downward, the tetrahedral boss is out of contact with the connecting rod, the No. 2 spring rebounds automatically, and the positioning plate clamps the corrugated cardboard in a self-centering manner. The positioning position has high accuracy, which can improve the cutting accuracy.

[0013] 2. When the electric cylinder moves upward, the tetrahedral boss pushes open the positioning plate, which can be connected to other feeding mechanisms such as the feeding mechanism on the assembly line, and the corrugated paper can be thrown into any position on the cutting table without manual assistance, which is convenient for feeding.

[0014] 3. The utility model cooperates with each other through the No. 1 spring, the knife seat, the threaded rod, the sliding rod, the pressing knife and the knife die. Before cutting, the corrugated cardboard is first shaped and flattened, and then the pressing knife passes through the knife hole on the knife die to cut the cardboard, avoiding inaccurate cutting due to moisture and unevenness on the cardboard surface, and buffering is performed by the No. 1 spring to avoid compression damage to the internal structure of the corrugated paper due to excessive inertia of the knife seat.
