A cutting groove 254 is opened on the upper end surface of the concave frame 252.

[0031] The abutment plate 253 is lifted by a spring so that the abutment plate 253 is always in contact with the bottom of the aluminum plate, and when the aluminum plate is cut, the setting of the cutting groove 254 can guide the cutting knife 357 to avoid deformation and deviation of the aluminum plate when the aluminum plate is cut and painted.

[0033] A side frame 351 is fixedly installed on one side of the support frame 35, and an electric push rod 352 is fixedly installed on one side of the side frame 351. A rack 353 that is slidably connected to the upper end surface of the side frame 351 is fixedly installed on the telescopic end of the electric push rod 352. A regulating wheel 354 is meshed on the upper part of the rack 353. The regulating wheel 354 is rotatably connected to the middle part of the support frame 35. A round rod is fixedly installed in the middle part of the regulating wheel 354, and a slitting frame 355 is fixedly installed on the round rod. A driving shaft 356 is installed in the middle part of the slitting frame 355 for transverse rotation through an electric slider, and a cutting knife 357 located in the middle part of the slitting frame 355 is fixedly installed on the driving shaft 356.

[0034] When the electric slider is opened, it drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, the lifting plate 34 is driven to rise and fall through the lifting block 33. When the lifting plate 34 is lifted and lowered, the inner block 312 is pressed down or lifted up through the bevel groove 340, thereby adjusting the spacing between the multiple vertical plates 311 in the dovetail groove 310, and then adjusting the spacing between the multiple cutting knives 357, so as to realize the slitting and spraying operations of aluminum profiles with different widths.

[0035] By controlling the extension and retraction of the electric push rod 352, the rack 353 moves forward and backward. When the rack 353 moves forward and backward, it drives the regulating wheel 354 to rotate. When the regulating wheel 354 rotates, it drives the slitting frame 355 and the cutting knife 357 to rotate along the axis of the regulating wheel 354, and then the cutting depth of the cutting knife 357 when starting slitting is regulated to meet the cutting requirements of aluminum profiles of different thicknesses.

[0037] A rotating plate 364 is fixedly installed at one end of the rotating shaft 361 away from the movable sleeve 36, a center plate 37 is fixedly installed in the middle of the supporting frame 35, a threaded rod 371 is threadedly installed in the middle of the center plate 37, a T-block 372 is threadedly installed on the threaded rod 371, the T-block 372 is slidably connected to the center plate 37, and knocking plates 373 are rotatably installed on both sides of the center plate 37, and the cylinder on one side of the rotating plate 364 is located in the knocking plate 373 and slides.

[0038] The electric slider is opened to drive the drive shaft 356 to rotate, and when the drive shaft 356 rotates, it drives the cutting knife 357 to cut the aluminum profile. The drive shaft 356 rotates to synchronously drive the rotating plate 364 to rotate through the setting of the pulley 362 and the belt 363. When the rotating plate 364 rotates, it drives the knocking plate 373 to knock up and down. When the knocking plate 373 knocks up and down, it intermittently presses the pressing plate 383, so that the paint spraying tube 382 sprays paint on the aluminum plate. By rotating the threaded rod 371, the T-block 372 slides back and forth in the center plate 37. At this time, the knocking plate 373 slides with the T-block 372, so that the up and down knocking range of the knocking plate 373 is adjusted, so that when it presses the pressing plate 383, the paint spraying intensity in the paint spraying tube 382 is adjusted, thereby adjusting the range of painting the aluminum plate.

[0039] The support frame 35 is symmetrically provided with sliding rods 38 on the front side. The sliding rods 38 penetrate and slide in the support frame 35.

[0041] When the present invention is in use, when fixing aluminum profiles of different specifications before processing, the electric slider is turned on to drive the adjustment plate 242 to slide in the adjustment slot 241, and the right-angle plate 245 is adjusted to slide in the diagonal slot 243, so as to achieve the limit fixation of the four corners of the aluminum profiles of different specifications, so as to meet the fixation of aluminum profiles of different specifications during processing. After the aluminum profiles are fixed, the motor is then turned on to drive the gear 215 to rotate, and the gear 215 rotates to drive the moving plate 216 to move toward the slitting and spraying unit 3. At this time, the extension plate 217 on the moving plate 216 drives the T-plate 22 to move, and the T-plate 22 drives the supporting plate 24 through the spring rod 23, and finally drives the aluminum profiles on the supporting plate 24 to perform the conveying operation; The electric slider is opened to drive the rotating rod 32 to rotate.

When the multiple vertical plates 311 are moved and adjusted, the external block 251 is driven to move on the middle frame 25 through the setting of the synchronous plate 313, so that the cutting knife 35 When cutting the aluminum profile, the abutment plate 253 always abuts against the aluminum profile below the cutting knife 357, and the cutting groove 254 provided on the abutment plate 253 guides the cutting knife 357, and controls the extension and contraction of the electric push rod 352 so that the rack 353 moves forward and backward. When the rack 353 moves forward and backward, it drives the regulating wheel 354 to rotate. When the regulating wheel 354 rotates, it drives the slitting frame 355 and the cutting knife 357 to rotate along the axis of the regulating wheel 354, thereby regulating the cutting depth of the cutting knife 357 when starting slitting, so as to meet the cutting requirements of aluminum profiles of different thicknesses; The electric slider is opened to drive the drive shaft 356 to rotate, and when the drive shaft 356 rotates, it drives the cutting knife 357 to cut the aluminum profile. The drive shaft 356 rotates to synchronously drive the rotating plate 364 to rotate through the setting of the pulley 362 and the belt 363. When the rotating plate 364 rotates, it drives the knocking plate 373 to knock up and down. When the knocking plate 373 knocks up and down, it intermittently presses the pressing plate 383, so that the paint spraying tube 382 sprays paint on the aluminum plate. By rotating the threaded rod 371, the T-block 372 slides back and forth in the center plate 37. At this time, the knocking plate 373 slides with the T-block 372, so that the up and down knocking range of the knocking plate 373 is adjusted, so that when it presses the pressing plate 383, the paint spraying intensity in the paint spraying tube 382 is adjusted, thereby adjusting the range of painting the aluminum plate.
