[0036] The curved blade assembly includes a servo motor 333 and a curved blade drive shaft 316. The servo motor 333 is fixedly mounted on the machine tool base plate 1. The output end of the servo motor 333 is connected to the input end of a diaphragm coupling 335. The output end of the diaphragm coupling 335 is connected to a synchronous belt 337. A synchronous pulley 338 is connected to the synchronous belt 337. A synchronous pulley 336 is connected to the synchronous pulley 338. A curved blade fixing plate 328 is fixedly mounted on the synchronous pulley 336. The curved blade drive shaft 316 is rotatably mounted on a mounting bracket 315.

The cylinder arm of the cylinder 323 is connected to the curved scissor roller shaft 317 and the curved scissor roller shaft 318.

[0038] Through the above scheme, the lightbox profile enters between the fixed feeding roller 303 and the movable feeding roller 304, causing the seven-star handle 302 to slide on the support plate 2, thus locking the lightbox profile between the two deep groove ball bearings 301. Then, the seven-star handle 302 is tightened, and the cylinder 325 is activated. The cylinder arm of the cylinder 325 extends, and the cylinder arm drives the movable feeding roller 304 to approach the lightbox profile through the cylinder mounting plate 327. Then, the lightbox profile is appropriately clamped by the fixed feeding roller 303 and the movable feeding roller 304. The servo motor 332 is activated, and the output end of the servo motor 332 drives the fixed feeding roller 310 to rotate through the elastic diaphragm coupling 334. The fixed feeding roller 310 drives the synchronous pulley 309 and the synchronous belt pulley 301. When the five-step pulley 330 rotates, the two-step pulley 309 drives the one-step pulley 306 to rotate via the one-step belt 307. The one-step pulley 306 drives a fixed feeding roller 303 to rotate, which in turn moves the lightbox profile. The five-step pulley 330 drives two six-step pulleys 331 to rotate via the three-step belt 329. The two six-step pulleys 331 then drive two fixed feeding rollers 340 to rotate. When the lightbox profile is transported between the right pressure plate 312 and the left pressure plate 313, and grooving is required, the servo motor 332 stops, and the cylinder 323 starts. The cylinder 323 drives the right pressure plate 312 and the left pressure plate 313 to restrain the lightbox profile, preventing displacement during grooving. Then, through... Cutting unit 4 slots the lightbox profile. The lightbox profile then enters between the fixed feeding roller 310 and the movable feeding roller 311. Two cylinders 308 are activated, extending their arms. These cylinder arms together drive the guide rail connecting plate 314, which in turn moves the movable feeding roller 311. The movable feeding roller 311 moves towards the fixed feeding roller 310, and the movable and fixed feeding rollers 311 and 310 appropriately clamp the lightbox profile slot. The rotation of the fixed feeding roller 310 and the fixed feeding roller 303 transports the lightbox profile. The lightbox profile slot passes between the back roller 341 and the fixed feeding roller 340 and then enters the curved blade roller shaft 317 and the curved blade. Between the two roller shafts 318, the servo motor 333 is started. The output of the servo motor 333 drives the synchronous belt 337 to rotate via the elastic diaphragm coupling 335. The synchronous belt 337 drives the synchronous pulley 336 to rotate via the synchronous pulley 338. The synchronous pulley 336 drives the curved blade fixing plate 328 to rotate. The synchronous belt 337 drives the curved blade drive shaft 316 to rotate. The curved blade drive shaft 316 drives the synchronous pulley 320 to rotate. The synchronous pulley 320 drives the synchronous pulley 319 to rotate via the synchronous belt 322. The synchronous pulley 319 drives the curved blade fixing plate 342 to rotate. The proximity switch 321 detects the rotation of the synchronous pulley 319 to prevent the synchronous pulley 319 from causing the curved blade fixing plate 342 to rotate excessively.The second curved blade fixing plate 342 and the first curved blade fixing plate 328 together drive the second curved blade rolling shaft 318 and the first curved blade rolling shaft 317 to rotate. The rotation of the first curved blade rolling shaft 317 and the second curved blade rolling shaft 318 causes the lightbox profile to bend.

[0044] Using the above method, slots are cut into the lightbox profile. The 57 motor 411 is started, and its output drives the first transmission pulley 414 to rotate. The first transmission pulley 414 drives the second transmission pulley 415 to rotate via the first transmission belt 413.

The switch baffle 409 interacts with two photoelectric switch sensors 4... 08. To prevent the upper plate 410 of the machine head from moving excessively, the upper plate 410 of the machine head drives the lower plate 402 of the machine head to move through three light column connecting shafts 401. The lower plate 402 of the machine head drives the angle offset component, the lifting component and the grooving component to move closer to the light box material, and starts the DC brushless motor 420. The output end of the DC brushless motor 420 drives the first flat belt pulley 431 to rotate. The first flat belt pulley 431 drives the second flat belt pulley 433 to rotate through the flat belt 432. The second flat belt pulley 433 drives the saw blade. 434 Grooves are cut into the lightbox panel. When the angle of the grooving component needs to be adjusted, stepper motor 403 is started. The output of stepper motor 403 drives transmission pulley 416 to rotate. Transmission pulley 416 drives transmission pulley 418 to rotate via transmission belt 417. Transmission pulley 418 drives rotating shaft 404 to rotate. Rotating shaft 404 drives arbitrary angle guide rail mounting plate 423 to rotate via aluminum bearing 425, thereby realizing the angle offset of the grooving component. When the grooving needs to be adjusted... When the component is raised or lowered, the 86 stepper motor 419 is started. The output end of the 86 stepper motor 419 drives the transmission pulley 424 to rotate. The transmission pulley 424 drives the transmission pulley 427 to rotate through the transmission belt 426. The transmission pulley 427 drives the guide rail motor connecting plate 430 to move through the synchronous belt toothed plate 428 and the synchronous belt pressing base plate 429. The guide rail motor connecting plate 430 drives the linear guide rail 436 to slide on the linear slider 437, thereby realizing the raising and lowering movement of the slotted component.
