Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile production and processing, and specifically relates to an aluminum profile production line. Background Art

[0002] Aluminum profiles are aluminum materials obtained by melting aluminum rods and then extruding them to obtain different cross-sectional shapes. The production process of aluminum profiles mainly includes three processes: melting and casting, extrusion, and coloring.

[0003] The prior art discloses a Chinese patent with the application number CN202410067624.9. An aluminum profile extrusion production line discloses that when the aluminum column body is fixed between the pressing seat and the supporting seat, the supporting mechanism continuously moves, so that the supporting mechanism is separated from the aluminum column body. At the same time, the supporting mechanism drives the pressing mechanism to move, so that the pressing mechanism continuously pulls the push rod to displace, so that the cutter is in close contact with the aluminum column body, and the aluminum column body is cut by the cutter, improving the stability of the aluminum column body during cutting.

[0004] Since the surface of the aluminum profile needs to be painted during production and processing, however, the above device can only perform single cutting on the aluminum profile, and cannot perform cutting and spraying synchronously. At the same time, the cutting range and cutting depth cannot be adjusted adaptively, so it brings certain limitations to production. Summary of the Invention

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] An aluminum profile production line is used for the auxiliary processing of metal profiles produced by non-rolling production. Aluminum profiles are mainly processed by extrusion and belong to one type of metal profiles.

[0036] As Figures 1 - 9 shown, it includes a bottom plate 1. A conveying unit 2 is provided on the upper end surface of the bottom plate 1. The conveying unit 2 includes symmetrically arranged side frames 21. T-shaped plates 22 are provided on the sides of the two side frames 21 close to each other. Spring rods 23 are symmetrically arranged on the upper end surfaces of the T-shaped plates 22. A placing plate 24 is fixedly installed between the two spring rods 23. A middle frame 25 is provided between the placing plates 24 on both sides. Guide frames 26 are symmetrically installed on the sides of the two side frames 21 away from each other. Moving grooves 261 are opened on the sides of the two guide frames 26 close to each other. A connecting plate 262 is slidably installed in the moving groove 261 through an electric slider. A slitting and spraying unit 3 is fixedly installed between the two connecting plates 262. An extruder 4 is fixedly installed on one side of the upper end surface of the bottom plate 1.

[0037] After fixing the aluminum profile plate to be sprayed and slit, the conveying unit 2 drives the aluminum profile plate to move towards the slitting and spraying unit 3, thereby realizing the slitting and spraying of the aluminum profile plate. And the setting of the slitting and spraying unit 3 also meets the requirement of slitting the aluminum profile plate into different widths. Finally, the slit and sprayed aluminum profile plate is placed in the extruder 4 for extrusion processing into the required profiles.

[0038] A conveying groove 212 is opened on the upper end surface of the side frame 21. A moving block 213 is slidably installed in the conveying groove 212. An adjusting rod 214 is rotatably installed in the middle of the moving block 213. A gear 215 is rotatably installed in the inner cavity of the side frame 21 through a motor. A moving plate 216 is meshed above the gear 215. The moving plate 216 is rotatably connected to the adjusting rod 214. An extension plate 217 is fixedly installed in the middle of the moving plate 216. One side of the extension plate 217 is fixedly connected to the T-shaped plate 22.

[0039] When conveying and processing the fixed aluminum profile plate, the motor is turned on to drive the gear 215 to rotate. When the gear 215 rotates, it drives the moving plate 216 to move towards the slitting and spraying unit 3. At this time, the extension plate 217 on the moving plate 216 drives the T-shaped plate 22 to move, and the T-shaped plate 22 drives the aluminum profile plate on the placing plate 24 to perform conveying operations through the spring rods 23.

[0040] Adjustment grooves 241 are provided around the upper end surface of the placement plate 24. An adjustment plate 242 is slidably installed in the adjustment grooves 241 through electric sliders. Diagonal grooves 243 are provided on the upper end surface of the adjustment plate 242. A diagonal plate 244 is slidably installed in the diagonal grooves 243 through electric sliders. Right-angle plates 245 are symmetrically provided on the front and rear sides of the placement plate 24 through electric sliders. A connecting rod 246 is rotatably installed on the side of the right-angle plate 245 away from the placement plate 24. One end of the connecting rod 246 is fixedly connected to the middle frame 25.

[0041] When fixing aluminum profile plates of different specifications before processing, the electric sliders are turned on to drive the adjustment plate 242 to slide in the adjustment grooves 241, and at the same time, the right-angle plates 245 are adjusted to slide in the diagonal grooves 243, so as to realize the limit fixation of the four corners of aluminum profile plates of different specifications, thus meeting the fixation requirements during the processing of aluminum profile plates of different specifications.

[0042] Multiple groups of outer blocks 251 are slidably installed on the front and rear sides of the middle frame 25. A concave frame 252 is fixedly installed between each group of outer blocks 251. A contact plate 253 is slidably installed in the middle of the concave frame 252. Multiple groups of springs are jointly connected between the contact plate 253 and the concave frame 252. A cutting groove 254 is provided on the upper end surface of the concave frame 252.

[0043] The contact plate 253 is lifted by the spring, so that the contact plate 253 is always in contact with the bottom of the aluminum profile plate. And when the aluminum profile plate is cut, the setting of the cutting groove 254 can guide the cutting knife 357, avoiding deformation and deviation of the aluminum plate during the slitting and painting of the aluminum profile plate.

[0044] The slitting and spraying unit 3 includes a fixed frame 31. A dovetail groove 310 is provided on one side of the fixed frame 31. Multiple groups of vertical plates 311 are slidably installed in the dovetail groove 310. An inner block 312 is fixedly installed on the upper part of the vertical plate 311. A synchronous plate 313 is fixedly installed on the lower part of the vertical plate 311. Rotating rods 32 are rotatably installed on both sides of the fixed frame 31 through electric sliders. Lifting blocks 33 are threadedly rotated on the rotating rods 32. A lifting plate 34 is fixedly installed between the two lifting blocks 33. Multiple groups of bevel grooves 340 are provided on the lifting plate 34. The bevel grooves 340 are located outside the inner block 312. A support frame 35 is fixedly installed in the middle of the vertical plate 311.

[0045] On one side of the support frame 35, a side frame 351 is fixedly installed. On one side of the side frame 351, an electric push rod 352 is fixedly installed. The telescopic end of the electric push rod 352 is fixedly installed with a rack 353 that is slidably connected to the upper end surface of the side frame 351. The upper part of the rack 353 is engaged with a regulating wheel 354. The regulating wheel 354 is rotatably connected to the middle of the support frame 35. A round rod is fixedly installed in the middle of the regulating wheel 354, and a slitting frame 355 is fixedly installed on the round rod. In the middle of the slitting frame 355, a driving shaft 356 is horizontally and rotatably installed through an electric slider. A cutting knife 357 located in the middle of the slitting frame 355 is fixedly installed on the driving shaft 356.

[0046] When the electric slider is turned on, it drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the lifting plate 34 to rise and fall through the lifting block 33. When the lifting plate 34 rises and falls, it presses down or lifts the built-in block 312 through the inclined groove 340, so as to adjust the distance between the multiple vertical plates 311 in the dovetail groove 310, and further regulate the distance between the multiple cutting knives 357, so as to realize the slitting and spraying operations of aluminum plates with different widths. When the multiple vertical plates 311 move and adjust, the setting of the synchronous plate 313 drives the external block 251 to move on the middle frame 25. Thus, when the cutting knife 357 cuts the aluminum plate, the abutting plate 253 always abuts against the aluminum plate below the cutting knife 357. The cutting groove 254 opened on the abutting plate 253 guides the cutting knife 357. Compared with the existing device, the present invention can effectively avoid the problem that the aluminum profile is prone to deformation during slitting due to its poor material hardness.

[0047] By controlling the telescopic movement of the electric push rod 352, the rack 353 moves back and forth. When the rack 353 moves back and forth, 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 further regulates the cutting depth when the cutting knife 357 starts slitting, so as to meet the cutting requirements of aluminum profiles with different thicknesses.

[0048] On the upper part of one side of the support frame 35, a moving sleeve 36 is slidably installed through an electric slider. On one side of the moving sleeve 36, a rotating shaft 361 is rotatably installed. Belt pulleys 362 are fixedly installed on one side of the rotating shaft 361 and the driving shaft 356 respectively. A belt 363 is installed between the two belt pulleys 362.

[0049] A rotating plate 364 is fixedly installed at one end of the rotating shaft 361 away from the moving sleeve 36. A central plate 37 is fixedly installed in the middle of the support frame 35. A threaded rod 371 is rotatably installed in the middle of the central plate 37. A T-shaped block 372 is rotatably installed on the threaded rod 371. The T-shaped block 372 is slidably connected to the central plate 37. Knocking plates 373 are rotatably installed on both sides of the central plate 37. The cylinder on one side of the rotating plate 364 slides in the knocking plate 373.

[0050] The electric slider is turned on to drive the drive shaft 356 to rotate. When the drive shaft 356 rotates, it drives the cutting knife 357 to cut the aluminum profile. When the drive shaft 356 rotates, the rotating plate 364 is synchronously driven to rotate through the arrangement of the belt pulley 362 and the belt 363. When the rotating plate 364 rotates, it drives the knocking plate 373 to knock up and down. The knocking plate 373 intermittently presses the pressing plate 383 during the up-and-down knocking, so that the paint spraying cylinder 382 sprays paint on the aluminum profile plate. By rotating the threaded rod 371, the T-shaped block 372 slides back and forth in the center plate 37. At this time, the knocking plate 373 slides along with the T-shaped block 372, so as to adjust the range of the up-and-down knocking of the knocking plate 373. Therefore, when pressing the pressing plate 383, the paint spraying intensity in the paint spraying cylinder 382 is adjusted, so as to adjust the range of spraying paint on the aluminum profile plate.

[0051] On the front side of the support frame 35, sliding rods 38 are symmetrically arranged. The sliding rods 38 penetrate and slide in the support frame 35. A placement rack 381 is fixedly installed on the common side of the two sliding rods 38 away from the support frame 35. A paint spraying cylinder 382 is detachably installed in the placement rack 381. A pressing plate 383 is slidably installed in the middle of the paint spraying cylinder 382. One end of the pressing plate 383 penetrates into the paint spraying cylinder 382 and a piston is fixedly installed.

[0052] The cutting frame 355 drives the cutting knife 357 to rotate. The electric slider drives the moving sleeve 36 to slide on the support frame 35, so as to ensure that the belt 363 on the two belt pulleys 362 does not fall off while controlling the cutting depth of the cutting knife 357, and further meet the requirement of spraying paint on the surface of the aluminum profile when the cutting knife 357 cuts the aluminum profile.

[0053] When in use, when fixing different specifications of aluminum profile plates before processing, the electric slider is turned on to drive the adjusting plate 242 to slide in the adjusting groove 241, and at the same time, the adjusting right-angle plate 245 slides in the diagonal groove 243, so as to realize the limit fixation of the four corners of different specifications of aluminum profile plates, thus meeting the fixation requirements during the processing of different specifications of aluminum profile plates. After the aluminum profile plate is fixed, the motor is turned on to drive the gear 215 to rotate. When the gear 215 rotates, it drives the moving plate 216 to move towards the cutting and spraying unit 3. At this time, the extension plate 217 on the moving plate 216 drives the T-shaped plate 22 to move. The T-shaped plate 22 drives the supporting plate 24 through the spring rod 23, and finally drives the aluminum profile plate on the supporting plate 24 to perform the conveying operation.

[0054] The electric slider is turned on to drive the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the lifting plate 34 to lift through the lifting block 33. When the lifting plate 34 lifts or lowers, it presses down or lifts the built-in block 312 through the bevel groove 340, so as to adjust the distance between the multiple vertical plates 311 in the dovetail groove 310, and further control the distance between the multiple cutting knives 357, so as to realize the slitting and spraying operations of aluminum plates with different widths. When the multiple vertical plates 311 are adjusted by moving, the setting of the synchronous plate 313 drives the external block 251 to move on the middle frame 25. Thus, when the cutting knife 357 cuts the aluminum plate, the abutting plate 253 always abuts against the aluminum plate under the cutting knife 357. The cutting groove 254 opened on the abutting plate 253 guides the cutting knife 357. By controlling the expansion and contraction of the electric push rod 352, the rack 353 moves back and forth. When the rack 353 moves back and forth, 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 further controls the cutting depth when the cutting knife 357 starts slitting, so as to meet the cutting requirements of aluminum profiles with different thicknesses;

[0055] The electric slider is turned on to drive the drive shaft 356 to rotate. When the drive shaft 356 rotates, it drives the cutting knife 357 to slit the aluminum profile. The rotation of the drive shaft 356 synchronously drives the rotating plate 364 to rotate through the settings of the belt 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 cylinder 382 sprays paint on the aluminum plate. By rotating the threaded rod 371, the T-shaped block 372 slides back and forth in the central plate 37. At this time, the knocking plate 373 slides with the T-shaped block 372, so as to adjust the range of the up and down knocking of the knocking plate 373. Thus, when it presses the pressing plate 383, the paint spraying intensity in the paint spraying cylinder 382 is adjusted, so as to adjust the range of spraying paint on the aluminum plate.
