[0030] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the drawings.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0032] To facilitate understanding of the multi-directional cutting device for foam plastics provided in this application, its application scenario is first explained. In current manufacturing processes, foam plastic sheets of different sizes are used as inner lining boards. High cutting precision is often achieved using heated blades or laser cutting to cut the foam plastic sheets to standard dimensions. However, in actual cutting, due to the varying required specifications of the foam plastic sheets—sometimes cutting in one direction, sometimes in two perpendicular directions, and sometimes in four directions to create a rectangular shape—the diverse cutting requirements in manufacturing necessitate constant adjustments to the fixed position of the foam plastic for different sizes and cutting directions. Multiple adjustments easily lead to positional deviations, are cumbersome, and significantly reduce cutting precision, failing to meet the needs of various applications. Therefore, this application provides a multi-directional cutting device for foam plastics, offering the advantage of stable multi-directional cutting, meeting different cutting requirements, providing high cutting precision, accelerating cutting efficiency, and simplifying the cutting process.

[0033] refer to Figure 1 The multi-directional cutting device for foam plastic provided in this application includes a cutting platform 100, which serves as the supporting body in this application and is used to fix the foam plastic board. The cutting platform 100 is equipped with a plurality of magnetic fixing clips 200. Of course, in other embodiments of this application, the cutting platform 100 may have rotation and lifting capabilities, and the corresponding fixing clips can be matched to fix the foam plastic, which facilitates the stability of cutting. These are all technologies known to those skilled in the art and will not be described in detail here.

[0034] The main guide frame of the multi-directional foam plastic cutting device in this application is a rectangular frame 400, which is connected to the cutting platform 100 directly above it via a support assembly. The support assembly includes four support rods 300, all of which are inclined and support the bottom four corners of the rectangular frame 400. This provides a large cutting space. Furthermore, any two adjacent support rods 300 are arranged in an outward V-shape, increasing the space for placing the foam plastic. In this application, the foam plastic can be placed and fixed on the cutting platform 100 between two support rods 300 from any direction, making the overall operation flexible and versatile.

[0035] The rectangular frame 400 includes two sliding frames 410 arranged opposite each other, and two connecting frames 420 connected between the two sliding frames 410; the two connecting frames 420 are respectively connected to the two ends of the two sliding frames 410, providing stable frame support, and the cutting size can be changed by installing different limit blocks on the sliding frames 410.

[0036] Combination Figure 2 As shown, this application also includes a sliding rod assembly, which is located inside the rectangular frame 400 and reciprocates along a first direction of the rectangular frame 400; the sliding rod assembly reciprocates along the length direction of the two sliding brackets 410. Specifically, the sliding rod assembly includes: a sliding rod 500 that slides between the two sliding brackets 410; wherein, both ends of the sliding rod 500 are fitted with sliding sleeves 510 that are fitted onto the corresponding sliding brackets 410. The assembly method is simple and the sliding is smooth. In addition, as Figure 3 As shown, each sliding frame 410 has an arc-shaped groove 411 along its length, and the inside of the sliding sleeve 510 is rotatably connected to a universal ball bearing 511 that mates with the corresponding arc-shaped groove 411. This enhances sliding performance and ensures smoothness.

[0037] As can be seen from the above structure, when the sliding rod 500 is driven by an external force, it can slide back and forth along the two sliding frames 410. The overall sliding process is smooth, and stable linear motion is ensured during the sliding process. The first direction refers to the length direction of the two sliding frames 410.

[0038] The multi-directional cutting device for foam plastics in this application also includes a cutting slider, which is slidably mounted on a sliding rod assembly and reciprocates along a second direction of the sliding rod assembly. Specifically, the cutting slider includes a main sliding member 520 slidably mounted on a sliding rod 500 and a cutting device 600 fixedly connected to the bottom of the main sliding member 520. The main sliding member 520 slides along the length of the sliding rod 500. During the sliding process, the main sliding member 520 drives the cutting device 600 to precisely displace, ensuring cutting accuracy. The cutting device 600 is a laser cutting device 600 or a heated blade cutting device 600, and the height of the cutting device 600 relative to the main sliding member 520 is adjustable to accommodate cutting foam plastics of different thicknesses.

[0039] Please refer to the above. Figure 1 and Figure 2 As shown, it also includes a drive unit, which drives the cutting slider to make linear or rectangular circumferential cuts along a first and / or second direction via an elastic displacement rod assembly. A gantry frame 700 is assembled between the two connecting frames 420, and the drive unit is a drive motor 800 mounted on the gantry frame 700. It has stable driving performance.

[0040] The elastic displacement rod assembly includes: a drive disk 900 connected to the output shaft of a drive motor 800, and a displacement drive rod 910 that extends laterally through the drive disk 900 and is slidably connected to it. The first end of the displacement drive rod 910 is hinged to a main sliding member 520. A retaining ring 920 is provided at the second end of the displacement drive rod 910, and a spring 930 is coiled around the displacement drive rod 910 between the retaining ring 920 and the drive disk 900. When rotating to different positions, the displacement drive rod 910 extends and retracts accordingly, ensuring precise movement and cutting with preload under the action of the spring 930. The first end of the displacement drive rod 910 is connected to the main sliding member 520 via a hinge shaft 530, providing a relatively flexible range of motion.

[0041] As can be seen from the above structure, after the foam plastic is fixed on the cutting platform 100 and its position is stabilized, the drive motor 800 is activated accordingly for the edge to be cut. For example, when cutting a straight-edged foam board, the drive motor 800 drives the drive disk 900 to rotate, allowing the cutting device 600 to cut along either the first or second direction. The displacement drive rod 910 extends or retracts in response to the driving force, and the spring 930 deforms accordingly, keeping it in a pre-tensioned moving state. When cutting a right-angled bend, the drive motor 800 drives the cutting device 600 to cut along the first direction and then turns to the second direction for cutting, achieving a smooth, integrated cut. When cutting into a rectangle, the drive motor 800 drives the cutting device 600 to move linearly along one side of the first direction for cutting, then turns to move linearly along the second direction for cutting, and then turns to move linearly along the other side of the first direction for cutting, and so on, achieving a wraparound rectangular cut. The overall cutting accuracy is high, the performance is stable, and the cutting process is simplified.

[0042] In this application, the cutting slider can be moved back and forth along the first direction for cutting, and along the second direction for cutting. The first and second directions are cyclically alternated to achieve rectangular cutting. The overall cutting accuracy is high, which can meet different cutting needs and simplify the cutting process.
