[0002] In the leather and nonwoven fabric processing industry, cutting is a crucial step that directly impacts product quality and production efficiency. Currently, automated cutting devices still face challenges in design and application, including: how to effectively prevent operators from accidentally touching the cutting blade and causing injury, and how to achieve rapid disassembly and replacement of the cutting blade. To address these issues, we propose an automated cutting device for leather and nonwoven fabrics. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an automated cutting device for leather nonwoven fabric, which solves the above-mentioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an automated cutting device for leather nonwoven fabric, comprising a worktable, two sets of protective plates fixedly mounted on the top of the worktable, a drive cylinder fixedly mounted between the two sets of protective plates on the top of the worktable, a component cylinder sleeved on the piston rod of the drive cylinder, a component block fixedly connected to the bottom end of the component cylinder, a connecting rod fixedly connected to the bottom end of the component block, a cutting device fixedly connected to the component block via the connecting rod, and a cutting blade for cutting nonwoven fabric movably mounted between the inner walls of both sides of the cutting device, further comprising: A hand-protection component, installed on the outer surface of the cutting device, is used to prevent operators from accidentally touching the cutting blade and causing injury. A quick-release assembly, located on the cutting device, is used for quick disassembly of the cutting blade.

[0005] Preferably, each of the two sets of protective plates has a movable groove near the top on one side of each other, and crossbars are fixed to both sides of the component cylinder. The two sets of crossbars are slidably engaged in the two sets of movable grooves respectively.

[0006] Preferably, vertical limiting grooves are provided on both sides of the connecting rod.

[0007] Preferably, the anti-cutting component includes a protective cover, an inner rod, an outer rod, and a round cover. The outer wall of the cutting device is slidably fitted with the protective cover. The inner walls on both sides of the protective cover are fixedly connected to the inner rods near the top. The outer wall of the protective cover is fixedly connected to the outer sides of the two sets of inner rods respectively. The ends of the two sets of outer rods that are far apart from each other are rotatably fitted with round covers.

[0008] Preferably, the anti-cutting component further includes an arc plate and an arc groove. The two sets of round covers are fixedly connected to an arc plate near the top on opposite sides. Arc grooves adapted to the two sets of arc plates are opened on both sides of the component block. The two sets of arc plates are slidably connected in the two sets of arc grooves.

[0009] Preferably, the quick-release assembly includes a side mounting groove, a retaining plate, and insert rods. The side mounting groove is provided on one side of the cutting device. A retaining plate adapted to the side mounting groove is slidably engaged in the side mounting groove. Horizontal insert rods are fixedly connected to one side of the retaining plate near both sides. Both sets of insert rods are slidably engaged in the cutting blade.

[0010] Preferably, the quick-release assembly further includes a circular hole A and a circular hole B. The side mounting groove is provided with a circular hole A near both ends, and two sets of circular holes B are provided on the inner wall of one side of the cutting device. The insertion rod is slidably inserted into the circular hole B through the circular hole A.

[0011] Compared with the prior art, this utility model provides an automated cutting device for leather nonwoven fabrics, which has the following advantages: 1. This automated cutting device for leather and nonwoven fabrics effectively prevents operators from accidentally touching the cutting blade by incorporating an anti-cutting component on the outer surface of the cutting device. This significantly reduces safety risks during operation. The protective cover within the anti-cutting component covers the cutting blade when not in use, and its stability and reliability are ensured through a sliding connection design between an arc plate and an arc groove. When cutting is required, simply rotating the round cover raises the protective cover to expose the cutting blade, making operation simple and safe.

[0012] 2. This automated cutting device for leather nonwoven fabrics features a quick-disassembly component design that makes the removal and replacement of the cutting blade extremely convenient. A side mounting groove is provided on the cutting device, where a sliding locking plate is engaged. A rod securely connects the locking plate to the cutting blade, achieving a stable installation. When the cutting blade needs to be removed, simply push the protective cover upwards until its bottom extends beyond the top of the side mounting groove, then pull the locking plate outwards to disengage the rod from holes B and A. This allows the cutting blade to be easily removed from the cutting device, significantly saving maintenance time and costs.

[0013] 3. This automated cutting device for leather nonwoven fabric significantly enhances the stability of the cutting process by optimizing the structural design of the cutting device. The drive cylinder pushes the component cylinder to move linearly through the piston rod. The crossbars on both sides of the component cylinder slide in the moving groove, ensuring the straightness and stability of the cutting blade during the cutting process. At the same time, the limiting groove on the connecting rod cooperates with the inner rod on the protective cover to further limit the sliding trajectory of the protective cover, preventing it from shaking or shifting during the cutting process, thereby ensuring the stability and consistency of the cutting quality.

[0025] Working Principle: In use, the non-woven fabric is first placed on the workbench 1 and positioned below the cutting blade 8. The fabric is manually pressed to prevent displacement during cutting. When cutting is required, the drive cylinder 3 is activated, using its piston rod to push the component cylinder 4. The horizontal bars 9 on both sides of the component cylinder 4 slide within two sets of moving grooves 10, ensuring stability during sliding. The cutting blade 8 cuts the non-woven fabric during this sliding motion. When protection of the cutting blade 8 is needed, the two sets of round covers 15 are rotated 90 degrees, causing the two sets of arc plates 16 to slide out of the two sets of arc grooves 17. After the arc plates 16 slide out of the arc grooves 17, the protective cover 11 slides downwards under gravity. When the two sets of inner rods 12 are in the limiting groove 13... When the cutter slides to the bottom, the bottom of the protective cover 11 is flush with the bottom of the cutter 8, preventing the cutter 8 from being accidentally touched by hand when the cut non-woven fabric is being picked up. When the cutter 8 needs to be disassembled, the protective cover 11 is pushed upward so that the bottom of the protective cover 11 exceeds the top of the side mounting groove 18. The card plate 19 can then be pulled outward in the side mounting groove 18, causing the insert rod 20 to disengage from the round holes B22 and A21 respectively. Finally, the insert rod 20 is pulled out on the cutter 8 to disassemble the cutter 8. During the sliding process of the cutter 8, the protective cover 11 wraps around the card plate 19, preventing the card plate 19 from sliding out of the side mounting groove 18, thus ensuring the stability of the cutter 8 during cutting.
