Description

Technical Field

[0001] This utility model relates to paper cutting equipment, specifically, to a combined paper cutting machine. Background Technology

[0002] In industries such as paper processing, printing, and packaging, paper cutters are indispensable pieces of equipment. Traditional paper cutters typically employ a fixed structure with a fixed table size and a single type of cutter, making it difficult to meet diverse cutting needs. For example, in greeting card making and gift packaging, decorative cutters are often used to cut out intricate shapes; in ticket and label production, perforated cutters enable easy tearing; in cardboard box manufacturing, folding cutters assist in precise folding; and ordinary paper cutting relies on straight-edge cutters. However, traditional paper cutters are often only equipped with straight-edge cutters. When customers require different processing techniques such as decorative cutters, perforated cutters, and folding cutters, the fixed structure of the paper cutter cannot be quickly adapted, necessitating the purchase of new equipment, which significantly increases equipment costs and space requirements. At the same time, the single cutter configuration limits the functionality of the paper cutter, making it difficult to cope with increasingly complex paper processing needs.

[0003] With the increasing demand for personalized and diversified paper processing, paper cutters that can be flexibly adjusted according to customer needs have become an urgent need in the industry. Although some existing paper cutters have adjustable tables or replaceable cutters, they suffer from problems such as limited combination methods, complex replacement operations, and poor structural stability. They cannot efficiently meet the needs of frequent switching between different cutters such as decorative cutters, dotted line cutters, folding line cutters, and straight edge cutters in actual production scenarios. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a combined paper cutter.

[0005] According to the present invention, a combined paper cutter includes a table device, a roller cutter device, a side cutter device, a roller cutter assembly, and an anti-slip pad. The roller cutter device is provided on the left side of the table device, and the roller cutter assembly is installed on the upper limit of the roller cutter device. The side cutter device is provided on the right side of the table device.

[0006] In a preferred embodiment: the tabletop device includes a table body and a tabletop cover plate. The table body has an internal partition, and the table body cover plate can rotate to cover the internal partition. The front and rear end faces of the table body are provided with fixing grooves. The upper and lower sides of the bottom of the fixing groove are provided with inner slots. A sliding fastener is provided in the fixing groove. A limit block is fixedly installed on the side of the sliding fastener near the table body. The limit block is located in the inner slot.

[0007] In a preferred embodiment: the roller cutter table device includes a plastic table base, a cutter pad, and a plastic table cover. A groove is provided in the middle of the upper end of the plastic table base, and the cutter pad is placed in the groove of the plastic table base. The top of the plastic table base is fixed by the plastic table cover.

[0008] In a preferred embodiment: the rotary cutter assembly includes a cutter holder fixing cover, a spring, a cutter holder movable seat, a cutter holder fixing seat, a blade fixing shaft, and a blade. The cutter holder fixing cover is engaged with the top of the cutter holder movable seat. Two symmetrical springs are provided between the cutter holder fixing cover and the cutter holder movable seat to ensure that the blade can adapt to the thickness of the paper during the pressing and cutting process. The cutter holder fixing seat is fixedly installed in the middle of the cutter holder movable seat. The blade fixing shaft is rotatably installed in the middle of the cutter holder fixing seat, and the blade is fixedly installed on the blade fixing shaft.

[0009] In a preferred embodiment: the blade includes a lace blade, a dotted line blade, a zigzag line blade, and a straight edge blade.

[0010] In a preferred embodiment: the side blade holder device includes a cutting blade fixing seat and a handle. The handle is provided on the right side of the cutting blade fixing seat. A long screw is provided at the rear end of the handle, and the long screw passes through the cutting blade fixing seat and is screwed with a nut. A washer is provided between the handle and the cutting blade fixing seat, and a disc spring washer is provided on the right side of the handle. The washer and the disc spring washer isolate the cutting blade fixing seat, the handle and the long screw from direct friction, so as to facilitate the rotation of the handle. The bottom of the handle is fixed to the cutting blade by multiple screws.

[0011] In a preferred embodiment: the cutting blade includes a rough edge cutting blade, a wave cutting blade, a stamp cutting blade, and a triangle cutting blade.

[0012] In a preferred embodiment: a paper pressing sheet is mounted on the cutter holder.

[0013] In a preferred embodiment: both the side cutter head device and the hobbing cutter assembly are provided with limiting slots corresponding to the fixing slots, and the sliding fasteners correspond to the limiting slots.

[0014] In a preferred embodiment: several anti-slip pads are fixedly installed on the bottom of the table device, the bottom of the hobbing table device, and the bottom of the side cutting table device. The anti-slip pads are made of rubber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When this utility model is used, the fixed groove, sliding clip, limiting clip and limiting groove of the table device form a sliding snap-fit ​​structure, which can quickly disassemble and assemble the roller cutter table device and the side cutter table device, and flexibly replace the blade of the roller cutter assembly and the cutting blade of the side cutter table device. Thus, the modular design realizes flexible expansion of functions and reduces equipment cost and space occupation.

[0017] 2. When using this utility model, the symmetrical springs between the blade holder fixing cover and the blade holder movable seat can automatically adapt to the paper thickness. There is no need to manually adjust the force when pressing and cutting, ensuring that the blade is in close contact with the paper surface, improving cutting accuracy and continuity. It is suitable for batch processing of paper of different thicknesses. The handle is connected to the cutting blade fixing seat through long screws, washers and disc spring washers. When turning the handle, the lever principle is used to press down with less effort, and the paper pressing plate fixes the paper. The operation is convenient and smooth, reducing human fatigue, and is especially suitable for high-frequency cutting operations. Attached Figure Description
