Description

Technical Field

[0001] The utility model relates to the field of cutting tools, in particular to a cutting device for cutting light and soft materials. Background Art

[0002] When cutting relatively soft materials, due to the material's variability and easy entanglement, the cutter device in the existing technology cannot provide tool contact pressure or initial tilting force during cutting, resulting in the material not being cut continuously, the cutting being insufficient, or the cutting accuracy not meeting the requirements, thus affecting the processing progress.

[0003] The utility model patent application number 202020552373.0 discloses a belt-breaking knife assembly device. A cutter cylinder is used to propel the blade within the cutting hole. The edge of the hole opposite the blade forms a cutting edge. The cutting edge is tilted to reduce vibration and noise generated when the belt breaks. This solution has a simple and sturdy structure, achieving stable cutting. However, this solution is designed for hard edge banding and cannot cut soft linear materials. Therefore, it cannot solve the technical problem of this application. Utility Model Content

[0004] Technical purpose: In order to overcome the deficiencies in the prior art, the utility model provides a cutter device to achieve fast and stable cutting of lightweight and soft linear materials.

[0005] Technical solution: To achieve the above-mentioned purpose, the utility model discloses a cutting device, including a frame, and also including a first straight cutter and a second straight cutter arranged on the frame and capable of approaching or moving away from each other. A spring is provided at one end of the second straight cutter, and the second straight cutter can rotate relative to the frame under the action of the spring.

[0006] Furthermore, two knife seats are provided on the frame, a rotating shaft is provided between the two knife seats, and the second straight cutting knife is provided on the rotating shaft.

[0007] Furthermore, the end of one end of the rotating shaft is connected to the end of the connecting rod, and the other end of the connecting rod is connected to the frame through the spring.

[0008] Furthermore, the first straight cutting knife is arranged on a movable plate, and the movable plate moves back and forth along a slide rail under the drive of a cylinder.

[0009] Furthermore, the second straight cutter and the first straight cutter are arranged at a certain angle in the moving direction of the first straight cutter, and when the first straight cutter and the second straight cutter approach each other, the point on the second straight cutter that first contacts the first straight cutter is defined as the entry point.

[0010] Furthermore, the entry point and the first straight cutting knife are distributed vertically.

[0011] Furthermore, it also includes a limiting rod, which is arranged on the movable plate or the knife seat and is used to limit the first straight cutter and the second straight cutter when they approach each other.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The cutting device of the utility model realizes fast and stable cutting of materials by arranging a second straight cutting knife that can rotate slightly with the rotating shaft and cooperating with the first straight cutting knife driven by the cylinder; by arranging a spring at the end of the second straight cutting knife, the contact pressure of the two straight cutting knives is guaranteed, ensuring that the tool can stably cut the material to be cut during the cutting process, avoiding the reduction of cutting quality or cutting failure due to loosening of the tool, and at the same time playing the role of buffering and shock absorption, reducing hard collisions between the tools, reducing tool wear, extending the service life of the tools, and further improving the stability and reliability of the cutting device.

[0018] The following is combined with Figure 1 To the attached Figure 3 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] A cutting device includes a frame, and also includes a first straight cutter 1 and a second straight cutter 2 mounted on the frame, which can move toward or away from each other. The first straight cutter 1 and the second straight cutter 2 move toward each other to complete the cutting process. A spring 3 is provided at one end of the second straight cutter 2, which allows the second straight cutter 2 to rotate relative to the frame under the action of the spring 3.

[0020] Specifically, two knife seats 4 are provided on the frame, with a rotating shaft 5 disposed between the two knife seats 4. The rotating shaft 5 can rotate relative to the knife seats 4 and the frame. The second straight cutter 2 is disposed on the rotating shaft 5 and can rotate synchronously with the rotating shaft 5. Specifically, one end of the rotating shaft 5 extends out of the knife seats 4 and is connected to the end of a connecting rod 6. The other end of the connecting rod 6 is connected to the frame via a spring 3. Figure 3 This is the main view of the present invention. Under the action of the spring 3, the spring 3 pushes one end of the connecting rod 6, so that the rotating shaft 5 drives the second straight cutter 2 to generate a counterclockwise rotation trend.

[0021] The first straight cutter 1 is set on the moving plate 8, and the moving plate 8 moves back and forth along the slide rail 9 under the drive of the cylinder 7. Figure 2 The figure is a top view of the cutting device of the present invention, in which the second straight cutter 2 is arranged at a certain angle to the first straight cutter 1 in the direction of movement of the first straight cutter 1. In one embodiment, the blade of the first straight cutter 1 is perpendicular to its moving direction, and the blade of the second straight cutter 2 is at a certain angle to the moving direction of the first straight cutter 1. When the second straight cutter 2 and the first straight cutter 1 approach each other, the point on the second straight cutter 2 that first contacts is defined as the entry point 11. Figure 3 As shown, the cutting point 11 is distributed above and below the first straight cutter 1 , that is, the cutting point 11 is arranged above the first straight cutter 1 .

[0022] In order to protect the blade, a limiting rod 10 can also be provided on the movable plate 8 or the knife seat 4 to limit the first straight cutter 1 and the second straight cutter 2 when they approach each other.

[0023] During use, the material falls between the first straight cutter 1 and the second straight cutter 2. The first straight cutter 1 approaches the second straight cutter 2 under the push of the cylinder 7. When the first straight cutter 1 contacts the entry point 11, the second straight cutter 2 can be pressed against the first straight cutter 1 due to the action of the spring 3, ensuring the contact pressure between the two straight cutters to complete the cutting of the material. After the cutting is completed, the first straight cutter 1 moves away from the second straight cutter 2 under the push of the cylinder 7 and completes the reset.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
