[0018] In this embodiment, a screw 302 is rotatably fitted between the inner walls of both sides of the fixing frame 301. A motor 303 is fixedly installed on the outer wall of the fixing frame 301.

The top of the upper cutting mold 404 is fixedly connected to the end of the telescopic shaft of the hydraulic rod 403.

[0019] Specifically, the material enters the automatic leveling unit 2, and multiple sets of adjustable-gap leveling rollers 8 are pre-adjusted according to the material thickness. The initial uniform leveling is completed through continuous rolling. Subsequently, the co-feeding unit 3 is started, and the motor 303 on the outer wall of the fixed frame 301 drives the screw 302 to rotate, which drives the threaded displacement block 304 to slide horizontally along the fixed frame 301. At the same time, the electric push rod 306 on the top of the displacement block 304 extends and retracts, so that the bottom wall of the through groove 305 and the clamping block 307 at the end of the electric push rod 306 close and clamp the material. The material is accurately delivered to the hydraulic cutting unit 4 through the precise transmission of the screw 302. After reaching the cutting station, the hydraulic rod 403 of the hydraulic cutting unit 4 extends and retracts, driving the upper cutting mold 404 to slide down along the fixed rod of the fixed frame 401, and cooperate with the lower cutting mold 402 to complete the cutting.

[0020] In this embodiment, the adjustment assembly 6 includes a displacement plate 601 slidably fitted onto a fixed plate 5. Two opposing adjustment plates 602 are slidably fitted above the displacement plate 601. An open groove 603 is provided on the upper side of the fixed plate 5, and the displacement plate 601 slidably fits into the groove 603. An adjustment groove 604 is provided on the upper side of the displacement plate 601, which slidably fits into the bottom connecting strips of the two adjustment plates 602. Limiting grooves 605 are provided on both inner walls of the groove 603. Reset blocks 606 are provided on both sides of the displacement plate 601, and the reset blocks 606 are respectively located within the limiting grooves 605 on both sides and abut against their inner walls. A groove 607 is provided at the bottom of the displacement plate 601, communicating with the two adjustment grooves 604. The bottom connecting strips of the two adjustment plates 602... One side of each of the two adjustment plates 602 is fixedly connected to a rack 608 that slides within a groove 607. A gear 609 is rotatably fitted to the bottom wall of the middle part of the groove 607. The gear 609 is located between and meshes with the two racks 608. A torsion spring 610 is provided at the point where the gear 609 rotates with the bottom wall of the groove 607. A beveled locking block 611 is fixedly connected to one side of the bottom connecting strip of each of the two adjustment plates 602. A reset groove 612 is provided on the inner wall of the adjustment groove 604. A reset strip 613 slides within the reset groove 612. The reset strip 613 is fixedly connected to one side of the reset block 606. A spring 614 is fixedly connected between one side of the reset strip 613 and the inner wall of the reset groove 612. A plurality of locking slots 615 that cooperate with the beveled locking block 611 are provided on one side of the reset strip 613.

[0021] Specifically, after cutting, the material enters the adjustment component 6 area. The displacement plate 601 slides along the groove 603 of the fixed plate 5 to adapt to the width of the material. The two adjustment plates 602 move synchronously in opposite directions through the meshing of the bottom rack 608 and the gear 609 in the groove 607, guiding and aligning the material to the center. The inclined edge locking block 611 cooperates with the slot 615 of the reset bar 613, locking the position of the adjustment plate 602 under the action of the spring 614. When the width needs to be adjusted, the displacement plate 601 is moved outward so that the reset block 606 drives the slot 615 of the reset bar 613 away from the inclined edge locking block 611. After unlocking, the torsion spring 610 drives the adjustment plate 602 to reset to adapt to materials of different widths.

[0022] When using the device, after material processing is started, it first enters the automatic leveling unit 2, where it is continuously rolled by multiple sets of adjustable-gap leveling rollers 8. The leveling rollers 8 are pre-adjusted according to the material thickness to achieve preliminary and uniform leveling of the material. Subsequently, the co-feeding unit 3 starts working. The motor 303 on the outer wall of the fixed frame 301 drives the screw 302 to rotate, which drives the displacement block 304, which is threaded to it, to slide horizontally along the inner walls on both sides of the fixed frame 301. At the same time, the electric push rod 306 on the top of the displacement block 304 extends and retracts, causing the clamping mechanism on the bottom wall of the through groove 305 to... The holding block 307 and the clamping block 307 at the end of the electric push rod 306 close together to firmly clamp the leveled material. The material is accurately conveyed to the hydraulic cutting unit 4 through the precise transmission of the screw 302. When the material reaches the cutting station, the hydraulic rod 403 of the hydraulic cutting unit 4 extends and retracts, driving the upper cutting die 404 to slide vertically downward along the fixed rod of the fixed frame 401, and precisely cooperate with the lower cutting die 402 to complete the material cutting. The cut material enters the area of ​​the adjustment component 6, and the displacement plate 601 slides horizontally along the slide groove 603 of the fixed plate 5 to adapt to the width of the material. The two adjusting plates 602 on the displacement plate 601 move synchronously in opposite directions through the meshing of the bottom rack 608 and the gear 609 in the groove 607, guiding and aligning the material on both sides to a centered position. The inclined edge locking block 611 at the bottom of the adjusting plate 602 cooperates with the locking groove 615 of the reset bar 613, and the position of the adjusting plate 602 is locked under the elastic force of the spring 614, ensuring the stability of the material position. By moving the displacement plate 601 outward, the reset block 606 abuts against the inner wall of the limiting groove 605 and continues to move outward. Plate 601, at this time, the reset block 606 drives the slot 615 on the reset bar 613 away from the inclined block 611, releasing the position lock of the adjustment plate 602. Through the force of the torsion spring 614, the adjustment plates 602 on both sides are driven to move further away, realizing the centering position of the material with different widths. In the whole process, the self-locking casters 7 at the bottom of the frame 1 are unlocked when the equipment needs to be moved, which facilitates the adjustment of the equipment position. When working, the casters are locked to ensure the stable operation of the equipment, thus completing the fully automated processing from leveling, feeding, cutting to adjustment.
