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

[0002] Corrugated paper, also known as corrugated cardboard, is composed of at least one layer of corrugated paper and one layer of box board paper bonded together, and has good elasticity and extensibility. It is mainly used for manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods. During the production process of corrugated cardboard, it is necessary to cut the corrugated paper into finished sizes to ensure good subsequent assembly of the corrugated paper.

[0003] Currently, when cutting corrugated paper, a paper cutter is used to cut the size of the corrugated paper. However, when using the cutting tool head to cut the paper, it is impossible to flatten the area around the cutting area well, which easily causes the paper to shake or become uneven during cutting, resulting in low cutting efficiency and affecting the cutting quality. At the same time, when cutting, it is necessary to rotate the turning handles on both sides to drive the baffle to limit the corrugated paper, which is rather troublesome to operate and cannot ensure that the fixed paper is at the center position of the cutting tool, reducing the cutting effect and efficiency.

[0004] Therefore, we propose a paper cutter for corrugated paper production to solve the above problems. Content of the Utility Model

[0033] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper in a waveform formed by a corrugating roll. It is generally divided into two categories: single corrugated cardboard and double corrugated cardboard, and is mainly used for manufacturing cartons. During the production process of corrugated paper, a paper cutter is required to cut its size.

[0034] In the related art, when the paper cutter for corrugated paper production cuts, it is unable to flatten the paper around the cutting knife, which will cause the paper to be uneven during cutting and affect the cutting quality. At the same time, when fixing and adjusting the corrugated paper, the operation is relatively cumbersome and the paper cannot be fixed directly below the cutting knife, affecting the cutting effect.

[0035] To solve the problems in the related art to a certain extent, the embodiment of this application provides a paper cutter for corrugated paper production. When it is necessary to cut corrugated paper, first place it on the base 110. By rotating the bidirectional threaded rod 330, drive two sliders two 320 to move in the chute 310, and then drive the baffle 340 to move, so as to limit and fix the corrugated paper placed on the base 110. In this way, the operation is more convenient and it can ensure that the fixed corrugated paper is directly below the cutting knife 140, thereby improving its cutting effect and efficiency. When the cutting knife 140 is pushed downward by the telescopic end of the telescopic cylinder 130, the pressing plate 260 also moves downward accordingly. The pressing plate 260 comes into contact with the corrugated paper to flatten it. The cutting knife 140 continues to move downward to cut the corrugated paper. At this time, the pressing plate 260 pushes the slider one 240 to move in the spring groove 220, squeezing the spring 230. Combining the elastic force of the spring 230, it can ensure that the pressing plate 260 always flattens the corrugated paper well when the cutting knife 140 is cutting, ensuring stability during cutting and improving the cutting quality of the corrugated paper.

[0036] The following describes this application with reference to the accompanying drawings and specific embodiments:

[0037] Combined with Figures 1-4, an embodiment of the present application provides a paper cutter for corrugated paper production, including: a bracket 120 is arranged on the top of a base 110; a telescopic cylinder 130 is arranged on the side wall of the bracket 120; a cutting knife 140 is arranged on the telescopic end of the telescopic cylinder 130, and a flattening mechanism 200 is arranged on the telescopic end of the telescopic cylinder 130. The flattening mechanism 200 includes: a fixed block 210 is arranged on the telescopic end of the telescopic cylinder 130; a spring groove 220 is opened on the side wall of the fixed block 210; a spring 230 is arranged in the spring groove 220; a first slider 240 is arranged at one end of the spring 230; a connecting rod 250 is arranged on the side wall of the first slider 240; a pressing plate 260 is arranged at one end of the connecting rod 250, and a limiting mechanism 300 is arranged on the base 110.

[0038] Specifically, a cutting knife 140 and a fixed block 210 are welded and fixed on the telescopic end of the telescopic cylinder 130, and there are two fixed blocks 210 symmetrically arranged on both sides of the cutting knife 140.

The side wall of the first slider 240 away from the spring 230 is welded and connected to the connecting rod 250, and the connecting rod 250 is welded and connected to the pressing plate 260.

[0039] When in use, first place the corrugated paper on the base 110. By starting the telescopic cylinder 130, drive the cutting knife 140 to move towards the corrugated paper. At the same time, the pressing plate 260 also moves towards the corrugated paper. When the pressing plate 260 comes into contact with the corrugated paper, the flattening work can be carried out on it. At this time, the cutting knife 140 needs to continue to move down to cut the corrugated paper. The pressing plate 260 is arranged in the spring groove 220 through the first slider 240, and moves to squeeze the spring 230. Through the elastic force of the spring 230, it can be ensured that when the cutting knife 140 moves down to cut the corrugated paper, the pressing plate always performs a good flattening work on the corrugated paper, thereby ensuring stability during cutting and improving the quality of corrugated paper cutting.

[0040] In some embodiments, the limiting mechanism 300 includes: a chute 310 is opened on the top of the base 110; a second slider 320 is slidably connected in the chute 310; a bidirectional threaded rod 330 is threadedly connected to the second slider 320; a baffle 340 is arranged on the side wall of the second slider 320.

[0041] Specifically, there are two second sliders 320, both of which are slidably connected in the chute 310, and the baffle 340 is welded and connected to the second slider 320.

[0042] During use, by rotating the bidirectional threaded rod 330, the two second sliders 320 are driven to move within the sliding groove 310, thereby driving the baffle 340 to move, and the corrugated paper placed on the base 110 is limited and fixed. The operation is more convenient, and at the same time, it can ensure that the fixed corrugated paper is always directly below the cutting knife 140, thereby improving the cutting effect and efficiency.

[0044] Specifically, there are two limiting grooves 270 and limiting blocks 280, which are symmetrically arranged on both sides of the spring groove 220, and the limiting block 280 is fixedly welded to the first slider 240.

[0045] During use, when the first slider 240 moves, its movement can be limited by the movement of the limiting block 280 within the limiting groove 270, and at the same time, the good movement effect of the first slider 240 can also be ensured.

[0046] In some embodiments, the bidirectional threaded rod 330 is arranged within the sliding groove 310, and one end of the bidirectional threaded rod 330 penetrates through the base 110 and is provided with a turning handle.

[0047] Specifically, the turning handle is fixedly welded to the bidirectional threaded rod 330.

[0048] During use, by rotating the turning handle, the bidirectional threaded rod 330 can be driven to rotate, and the operation is more rapid and convenient.

[0049] In some embodiments, the bidirectional threaded rod 330 is rotatably connected to the sliding groove 310 through a bearing.

[0050] During use, when the bidirectional threaded rod 330 rotates within the sliding groove 310, it can be more stable through the bearing.

[0051] In some embodiments, gaskets are provided on the side walls of the pressing plate 260 and the baffle 340.

[0052] Specifically, the gaskets are pasted on the side walls of the pressing plate 260 and the baffle 340.

[0053] During use, the backing plate can better protect the flattening and limiting work of the pressing plate 260 and the baffle 340 on the corrugated paper and avoid damaging it.

[0054] In some embodiments, a bottom plate 150 is provided on the top of the base 110.

[0055] Specifically, the bottom plate 150 is fixedly welded to the base 110.

[0056] During use, the base plate 150 can better fix the corrugated paper to improve the cutting quality.

[0057] In some embodiments, the first slider 240 is in a fitting arrangement with the spring groove 220.

[0058] During use, the first slider 240 can stably slide within the spring groove 220 to avoid displacement during sliding.
