Description

Technical Field

[0002] Currently, there are various methods for cutting soft fabrics, including manual shearing, laser cutting, water jet cutting, and electronic cutting. Laser cutting and electronic cutting are commonly used for companies requiring mass production. Laser cutting involves irradiating the cutting area with a high-energy-density laser beam, causing the material surface to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow (such as oxygen or nitrogen) coaxial with the beam is used to blow away the molten material, creating an incision in the material. Electronic cutting, also known as numerical control cutting or CNC cutting, utilizes computer numerical control technology to control cutting equipment and precisely cut materials. In electronic cutting, a computer controls the cutting machine's trajectory using pre-designed graphics or data, achieving precise cutting of the material. Electronic cutting is suitable for a variety of soft materials, such as paper, plastic, and rubber. It offers significant advantages in high-volume, high-precision material cutting.

[0046] Example

[0047] This embodiment is intended to promote the solution. Traditional laser cutting and electronic cutting are both equipped with CNC machine tools. However, CNC machine tools are large in size and occupy a large area. They require sufficient space for placement and operation and are limited to the use of special sites. In addition, the processing range is also subject to certain restrictions, and parts that exceed their own size range cannot be processed.

[0048] To this end, the purpose of this embodiment is to provide a portable soft material cutting device, which is small in size, easy to carry, and can be used in any fixed place. It can be directly used on the flat or inclined surface of the workbench to be processed. By pulling and transmitting the cable, it can meet the processing needs of parts of various sizes. It is suitable for a variety of cutting and processing operations and has a wide range of uses.

[0049] The soft materials mentioned in this embodiment include flexible cloth, flexible film, leather material, paper material, etc. Unlike traditional rigid material processing which requires fixture fixation, the portable soft material cutting device of this embodiment requires the soft material to be flat on the work surface and then fixed on the corners. Cloth, for example, needs to be kept taut, and the table surface must be flat. Traditional CNC machine tools have their specified processing size ranges, and processing cannot be performed if the size is exceeded. The portable soft material cutting device of this embodiment depends on the stroke length of the cable. According to the size of the soft material to be processed, a work surface that is greater than or equal to its size is matched, and the portable soft material cutting device is fixed to the work surface to cut the soft material. The portable soft material cutting device of this embodiment has no restrictions on whether the work surface is horizontal or inclined. If an inclined surface is used, the debris cut out can be better discharged from the work surface.

[0070] It should be added that the lifting transmission mechanism 111 of this embodiment can adopt the vertical slide in the prior art, and the vertical slide can include a servo motor, a reducer, a ball screw, a cross roller guide and a slide body 1: wherein the servo motor serves as a power source, and converts high-speed rotation into low-speed and high-torque output through the reducer to drive the ball screw to rotate. Ball screw: converts the rotational motion of the servo motor into linear motion. The nut of the ball screw is connected to the cross roller guide, and moves up and down with the rotation of the screw. Cross roller guide: provides high-precision guidance and support for the slide, ensuring the stability and accuracy of the slide during vertical movement.

[0071] Reference Figure 15 As shown, specifically, the main body 1 also includes a pad 16 that is in sliding contact with the work surface 2 or the surface of the soft material to be processed. The pad 16 is arranged at the bottom of the second support member 14. A movable notch 161 is provided in the middle of the pad 16. The middle of the first support member 13 and the second support member 14 are respectively provided with movable windows 141 that are compatible with the cutting assembly 11. The cutting assembly 11 can cut the material on the work surface 2 through the movable notch 161 and the movable window 141. A slip ring 162 for smooth connection with the work surface 2 is provided at the bottom of the movable notch 161. When the soft material to be processed covers the entire work surface 2, the pad 16 can contact the surface of the processed soft material through, but not limited to, the slip ring 162. The bottom of the smooth slip ring 162 can adopt an arc transition to avoid scratching the surface of the processed soft material. In addition to using the slip ring 162, some embodiments can also use universal wheels to replace sliding by rolling. It should be noted that the purpose of providing the movable notch 161 in the middle of the pad 16 is that the cutting assembly 11 can be disposed in the middle of the body 1 to facilitate positioning the starting point of cutting.
