All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a reciprocating fabric cutting machine, including a support 1, a hydraulic press 2 is fixedly installed at the top of the support 1, a cutting mechanism 3 is arranged at the lower end of the hydraulic press 2, and the cutting mechanism 3 includes:

[0025] The tool changing assembly 31 is arranged at the lower part of the hydraulic press 2 and includes a gantry plate 311 fixedly connected to the end of the hydraulic rod on the hydraulic press 2. At both sides of the top end of the gantry plate 311, first U-shaped blocks 312 are fixedly connected. Inside the first U-shaped blocks 312, L-shaped clamping rods 313 are rotatably installed. Inside the gantry plate 311, a rotating rod 315 is rotatably arranged, and both ends of the rotating rod 315 extend to the outside of the gantry plate 311 and are connected to a grooving block 314. The L-shaped clamping rod 313 can be cooperatively clamped into the clamping groove on the grooving block 314.

[0026] The transmission assembly 32 is arranged at the upper part of the gantry plate 311 and is used to drive the L-shaped clamping rod 313 to rotate.

[0027] In this embodiment, a number of cutting scissors 316 distributed in a circumferential array are fixed on the rotating rod 315, and the number of the cutting scissors 316 is the same as that of the clamping grooves on the grooving block 314.

[0028] In this embodiment, the transmission assembly 32 includes a threaded rotating rod 321 rotatably installed at the upper end of the gantry plate 311. A threaded block 322 is threadedly connected to the threaded rotating rod 321. At both ends of the threaded block 322, movable connecting rods 323 are rotatably installed, and at the other end of the movable connecting rod 323, a connecting block 324 is rotatably installed. At both sides of the top end of the gantry plate 311, second U-shaped blocks 325 are fixedly connected. On one side of the connecting block 324, a rack 326 that telescopically moves in a fixed direction along the inside of the second U-shaped block 325 is fixed. Inside the second U-shaped block 325, a gear 327 meshing with the rack 326 is rotatably installed. On one side of the gear 327, a transmission rod 328 is connected, and the L-shaped clamping rod 313 is driven to rotate through the transmission rod 328. When the threaded rotating rod 321 rotates, the threaded block 322 threadedly connected to it will move along the threaded direction. Both ends of the threaded block 322 are connected to the connecting block 324 through the movable connecting rods 323. This connection method enables the linear motion of the threaded block 322 to be converted into the horizontal movement of the connecting block 324; on the other side of the connecting block 324, a rack 326 is fixed. The rack 326 telescopically moves in a fixed direction along the inside of the second U-shaped block 325 fixed to the top end of the gantry plate 311. Inside the second U-shaped block 325, a gear 327 meshing with the rack 326 is rotatably installed. The rotation of the gear 327 is driven by the rack 326. When the gear 327 rotates, it will drive the L-shaped clamping rod 313 to rotate.

[0029] In this embodiment, a base 4 is fixed to the lower end of the bracket 1, and a cutting table 5 is fixed to the upper end of the base 4. A knife groove matching with the cutting scissors 316 is provided on the cutting table 5 to ensure the accuracy and stability of cutting.

[0030] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] During operation, first, the hydraulic press 2, as the power source, is fixedly installed at the top of the bracket 1. When cutting operations are required, the hydraulic press 2 is activated. Through the telescopic movement of its hydraulic rod, it drives the entire cutting mechanism 3 to descend until the cutting knife 316 approaches or contacts the fabric on the cutting table 5. The core of the cutting mechanism 3 lies in the tool-changing assembly 31, which allows for the quick replacement or adjustment of the position of the cutting knife in case of damage to the main cutting knife. Specifically, the gantry plate 311 of the tool-changing assembly 31 is connected to the hydraulic press 2 through a hydraulic rod. An L-shaped clamping rod 313 is rotatably installed within the first U-shaped block 312 at the upper end of the gantry plate 311. These L-shaped clamping rods 313 can cooperate with the card slots on the grooved block 314 to achieve the fixation and release of the cutting knife 316. The rotating rod 315 is fixed to the inner side of the gantry plate 311, and several groups of cutting knives 316 are evenly distributed thereon. The number of these cutting knives matches the number of card slots on the grooved block 314 to ensure the accuracy of tool change;

[0032] To achieve the automatic replacement or adjustment of the cutting knife, the transmission assembly 32 plays a key role. The transmission assembly 32 includes a threaded screw rod 321, which is rotatably installed at the upper end of the gantry plate 311. When the threaded screw rod 321 rotates, the threaded block 322 threadedly connected thereto will move along the threaded direction. Both ends of the threaded block 322 are connected to the connecting block 324 through movable connecting rods 323. This connection method enables the linear movement of the threaded block 322 to be converted into the horizontal movement of the connecting block 324; A rack 326 is fixed to the other side of the connecting block 324. The rack 326 undergoes directional telescoping along the inner side of the second U-shaped block 325 fixed to the top of the gantry plate 311. A gear 327 meshing with the rack 326 is rotatably installed within the second U-shaped block 325. The rotation of the gear 327 is driven by the rack 326. One side of the gear 327 is connected to the L-shaped clamping rod 313 through a transmission rod 328. Therefore, when the gear 327 rotates, it will drive the L-shaped clamping rod 313 to rotate, thereby achieving the insertion or release of the cutting knife 316 into the card slots on the grooved block 314;

[0033] During the cutting process, the fabric is placed on the cutting table 5. The cutting table 5 is provided with knife grooves that cooperate with the cutting knives 316 to ensure the accuracy and stability of cutting. With the drive of the hydraulic press 2 and the precise control of the transmission assembly 32, the cutting knives 316 can cut the fabric according to the preset trajectory and depth, achieving efficient and precise fabric cutting operations.
