Technical Field

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

[0002] Paper cutting is a basic operation in the printing, packaging and various paper processing industries. In the traditional paper cutting process, a cutter with a sharp blade is usually used to perform vertical up and down cutting. Although this cutting method can complete the cutting task to a certain extent, it also has some obvious shortcomings. The traditional cutter relies on the sharpness of the blade to achieve cutting, which causes the blade to wear easily during use and requires frequent replacement or sharpening, increasing maintenance costs and time. Due to the wear of the blade and the difference in the operator's operating skills, the edge of the cut paper may be uneven or burred, affecting the product quality. Utility Model Content

[0034] Reference Figure 1 to Figure 5 , is an embodiment of the utility model, and proposes

[0035] A paper cutting device, comprising:

[0036] Mounting frame 1;

[0037] A rotating shaft 2 is rotatably mounted on the mounting frame 1;

[0038] The cutting blade 3 is arranged on the rotating shaft 2, and is used to drive the cutting blade 3 to rotate after the rotating shaft 2 rotates;

[0039] The abutment block 4 is arranged on the mounting frame 1. After the cutting knife 3 rotates with the rotating shaft 2, it is used to abut or not abut the abutment block 4. After the cutting knife 3 abuts the abutment block 4, it is used to cut paper.

[0040] In this embodiment, since the cutting knife 3 of this scheme does not have a blade in the traditional sense, there is no problem of blade wear, which reduces maintenance costs and replacement frequency, and prolongs the service life of the equipment. The cutting knife 3 is driven to rotate by the rotating shaft 2, and the cutting is achieved by the abutment block 4. This cutting method can apply pressure more evenly, reduce the unevenness and burrs in the paper cutting process, and improve the cutting accuracy. Since the cutting knife 3 does not have a sharp blade, the risk of injury to the operator during operation is significantly reduced, and the safety of the production process is improved. The cutting knife 3 of the present invention achieves cutting by a rotary abutment method, and the rotation speed and pressure can be adjusted according to the thickness and material of the paper, so as to adapt to different specifications of paper, thereby enhancing the versatility and flexibility of the equipment. The paper cutting knife device of the present invention has a simple structure and is easy to operate and maintain. Since there is no complex blade system, the maintenance of the equipment is simpler and faster. The rotary abutment cutting method can cut quickly and continuously, improves the cutting efficiency, and is particularly suitable for mass production needs.

[0041] Furthermore, the cutting blade 3 is arranged on the rotating shaft 2 in a spiral shape.

[0042] In this example, the spirally arranged cutting blades 3 are continuously arranged on the rotating shaft 2, so that the cutting action can be performed continuously, thereby realizing an uninterrupted cutting process, further improving the cutting efficiency. When the spirally arranged cutting blades 3 rotate, they can apply a more uniform cutting force to the paper, reducing the risk of paper damage or incomplete cutting due to uneven pressure, and can cut the paper more smoothly.

[0043] Furthermore, the cutting end of the cutting blade 3 is arc-shaped.

[0044] In this embodiment, the arc-shaped cutting end can provide a smoother cutting track when in contact with the paper, reduce burrs and tearing of the paper edge, and thus improve the cutting quality. The pressure applied by the arc-shaped cutting end to the paper during the cutting process is more evenly distributed, reducing damage to the paper during the cutting process, and is particularly suitable for cutting thinner or fragile paper materials. Due to the continuous curve design of the arc-shaped cutting end, the friction resistance during the cutting process can be reduced, making the cutting action smoother, thereby improving the cutting speed.

[0045] Furthermore, it also includes:

[0046] The support block 5 is arranged on the mounting frame 1 . The support block 5 has a mounting groove 6 . The abutment block 4 is used to be arranged in the mounting groove 6 . The mounting groove 6 is arranged obliquely.

[0047] In this embodiment, the inclined mounting groove 6 on the support block 5 allows the abutment block 4 to be set at a certain angle, which helps to optimize the cutting angle, making the contact between the cutting blade 3 and the paper more precise and improving the cutting efficiency. The inclined mounting groove 6 allows the abutment block 4 to contact the paper with less resistance during the cutting process, reducing the force required for cutting, thereby reducing energy consumption.

[0048] Further, the support block 5 has a first adjustment hole 7, and further includes:

[0049] The top screw 8 is threadably disposed in the first adjustment hole 7 . After the top screw 8 is rotated in the first adjustment hole 7 , the top screw 8 is used to adjust the position of the abutment block 4 in the installation groove 6 .

[0050] Furthermore, the support block 5 has a second adjustment hole 9, and the first adjustment hole 7 and the second adjustment hole 9 are arranged vertically, and the second adjustment hole 9 is in a strip shape, and further includes:

[0051] The bolt 10 passes through the second adjusting hole 9 and is arranged on the abutting block 4 . After the top screw 8 is rotated, the bolt 10 slides in the second adjusting hole 9 .

[0052] In this embodiment, the top screw 8 in the first adjustment hole 7 can be rotated to adjust the position of the abutment block 4 in the installation groove 6, providing an accurate and simple adjustment method to ensure that the contact point between the cutting knife 3 and the abutment block 4 is accurately aligned. The first adjustment hole 7 and the second adjustment hole 9 are arranged vertically, so that the abutment block 4 can be adjusted not only in the horizontal direction but also in the vertical direction, providing multi-dimensional adjustment capabilities to adapt to paper of different thicknesses and sizes. Through the cooperation of the top screw 8 and the bolt 10, the operator can flexibly control the distance between the cutting knife 3 and the abutment block 4, thereby adjusting the cutting depth to meet different cutting requirements.

[0053] Further, the cutting blade 3 and the abutment block 4 form a cutting gap 11, and further include:

[0054] The paperboard 12 is arranged on the mounting frame 1 . The paperboard 12 is used to convey paper through. The paperboard 12 is connected to the cutting gap 11 . The paperboard 12 has an avoidance groove 13 . The avoidance groove 13 is used to avoid the cutting knife 3 .

[0055] Furthermore, it also includes:

[0056] The driving unit 14 is disposed on the mounting frame 1 , and is used to drive the rotating shaft 2 to rotate.

[0057] In this embodiment, the setting of the paperboard 12 enables the paper to pass through the cutting area smoothly, thereby improving the efficiency and continuity of paper transportation. The paperboard 12 is connected to the cutting gap 11, which helps to control the accuracy of the cutting gap 11 and ensure the stability and cutting quality of the paper during cutting. The avoidance groove 13 on the paperboard 12 is designed to avoid the cutting knife 3, effectively preventing the accidental contact between the cutting knife 3 and the paperboard 12 during paper transportation, thereby improving the safety of operation. By accurately controlling the relative position of the paperboard 12 and the cutting gap 11, the stability of the paper during the cutting process can be ensured, thereby improving the cutting accuracy. The setting of the drive unit 14 enables the rotation of the rotating shaft 2 to be automatically controlled, reducing manual intervention and improving the degree of automation of the entire cutting process.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
