Description

Technical Field

[0001] The present invention relates to the technical field of laser edge banding, and in particular to a laser edge banding machine used in an edge banding process. Background Art

[0002] Common board materials on the market today, whether density board, particle board, or solid wood, are all made of different-sized pieces of wood bonded together with glue. This glue generally contains large amounts of formaldehyde and has a long release cycle. To beautify the board's exterior and reduce the rate of formaldehyde release, board edge banding has been developed. These processes are generally divided into two categories: gluing and laser edge banding. Gluing is simple and inexpensive, but lacks aesthetic appeal and can cause edge splitting. Laser edge banding, on the other hand, creates aesthetically pleasing gaps and is less prone to edge splitting, but requires high process precision and equipment costs. Existing laser edge banding machines are often complex to operate and require high edge banding precision. They also lack the ability to automatically perform board edge banding, resulting in a low level of automation. Summary of the Invention

[0054] When the plate is transported to the active roller 219, the plate moves forward and drives the active roller 219 to rotate, thereby driving the active gear 218 to rotate, and driving the transmission gear 216 and the fixed worm 213 to rotate through the inclined transmission belt 217, driving the docking gear 212, the long rotating rod 214 and the groove rotating rod 210 to rotate, thereby driving the movable gear 209 and the movable worm 208 to rotate through the sliding gear 211, thereby driving the two worm wheels 207 to rotate synchronously, thereby driving the friction roller 205 to rotate, and through the friction The torsion spring 220 ensures that the friction plate 206 is always in close contact with the edge banding strip 203, and the edge banding strip 203 is continuously pulled out from the strip output tube 204 through the friction plate 206, so that the strip output tube 204 is in contact with the side of the plate.

The cutting electric cylinder 222 extends, and the strip output tube 204 is cut off by the cutting knife 223.

[0055] When the sliding frame 120 moves outward, it drives the sliding block 221 to slide outward along the middle frame 201, and the position of the sliding block 221 is adjusted according to the width of the plate.

[0056] like Figures 11-16 As shown, the rear device also includes a rear conveying motor 302 arranged next to the rear frame 301, and a rear gear 303 is fixedly installed on the motor shaft of the rear conveying motor 302. A plurality of rear conveying rollers 304 are rotatably installed on the rear frame 301, and a rear roller gear 305 is fixedly installed on the rear conveying roller 304. A rear transmission belt 322 is wrapped around the rear roller gear 305, and the rear gear 303 is engaged with the rear roller gear 305 next to it.

[0057] like Figures 11-16As shown, an upper arc plate 308 is slidably mounted on the rear frame 301 , a compression spring 309 is provided between the upper arc plate 308 and the rear frame 301 , and a cutter 310 is fixedly mounted on the upper arc plate 308 .

[0058] like Figures 11-16 As shown, a limit frame 315 is slidably installed on the rear frame 301, a reset spring 316 is provided between the limit frame 315 and the ground, a plurality of rotating blocks 317 are rotatably installed on the limit frame 315, a rotating block torsion spring 318 is provided between the rotating block 317 and the limit frame 315, and the reset rod 306 is slidably installed with the limit frame 315.

[0059] like Figures 11-16 As shown, a slide 312 is slidably installed below the rear frame 301, a downward pressure block 311 is slidably installed on the slide 312, the downward pressure block 311 is fixedly installed with the reset rod 306, a downward pressure spring 313 is provided between the downward pressure block 311 and the slide 312, and a slide spring 314 is provided between the slide 312 and the rear frame 301.

[0060] When the edge banding of the plate is completed, it continues to move forward and reaches the rear conveying roller 304. The rear conveying motor 302 rotates to drive the rear gear 303 to rotate, thereby driving the rear roller gear 305 to rotate, and through the rear transmission belt 322, all the rear roller gears 305 and the rear conveying roller 304 are driven to rotate. The rear conveying roller 304 conveys the plate. When the plate contacts the upper arc plate 308, the upper arc plate 308 and the cutter 310 are lifted up, and the compression spring 309 is compressed, so that the cutter 310 is in contact with the upper surface of the plate. In coordination with the advancement of the plate, the excess part of the edge banding strip is cut off by the cutter 310.

[0061] The movement of the bottom transmission belt 307 drives the toggle plate 320 and the reset rod 306 to slide through the pushing column 319, thereby driving the slide 312 and the lower pressure block 311 to move forward together, the slide spring 314 is stretched, the slide 312 pushes the rotating block 317 to rotate, and the rotating block torsion spring 318 is twisted. When the slide 312 passes the rotating block 317, the rotating block torsion spring 318 rebounds, and the cooperation of the rotating block 317 and the limit frame 315 makes the slide 312 unable to retreat. Since only the rotation of the front synchronous roller 122 can drive the bottom transmission belt 307 to move forward, the distance the lower pressure block 311 moves forward is consistent with the length of the plate; when the plate moves to the lower pressure block 311, the plate presses the lower pressure block 311 down, and the lower pressure spring 313 After the cam 314 is lifted up, the cam 315 is lifted up and the support frame 310 is in the upright position, and the cam 316 is in the upright position, so that the cam 314 can be lifted up and the support frame 310 is in the upright position.

[0062] The working principle of a laser edge banding machine for edge banding disclosed in the present invention is as follows: a plate to be edge banded is placed on the front conveying roller 102, the front motor 104 rotates to drive the front gear 105 to rotate, thereby driving the front roller gear 103 to rotate, and the front transmission belt 121 drives all the front roller gears 103 and the front conveying roller 102 to rotate, and the plate is conveyed by the front conveying roller 102. When the plate advances to the height triangle block 106, the height triangle block 106 will be lifted up, and the upper spring 107 will be compressed, thereby determining the thickness of the plate. When the plate contacts the width triangle block 108, the plate pushes the width triangle block 108 and the outer As the carriage 109, bottom carriage 113, and carriage 120 move outward, the spring between the carriage 120 and the front frame 101 is stretched, thereby adjusting the position of the carriage 120 and the sliding block 221 according to the width of the plate. As the bottom carriage 113 moves outward, it pushes the bottom stopper 116 to rotate, causing the limit torsion spring 117 to twist. After the bottom carriage 113 passes the bottom stopper 116, the limit torsion spring 117 rebounds, preventing the bottom stopper 116 from moving back. This maintains the position of the carriage 120 and the width triangle 108, preventing the spring between the carriage 120 and the front frame 101 from rebounding. When the plate moves onto the front synchronous roller 122, it pushes the front synchronous roller 122 to rotate, thereby driving the bottom transmission wheel 119 to rotate via the vertical transmission belt 118, thereby driving the bottom transmission belt 307 to move. When the plate is transported to the active roller 219, the plate moves forward and drives the active roller 219 to rotate, thereby driving the active gear 218 to rotate, and driving the transmission gear 216 and the fixed worm 213 to rotate through the inclined transmission belt 217, driving the docking gear 212, the long rotating rod 214 and the groove rotating rod 210 to rotate, thereby driving the movable gear 209 and the movable worm 208 to rotate through the sliding gear 211, thereby driving the two worm wheels 207 to rotate synchronously, thereby driving the friction roller 205 to rotate, and through the friction The torsion spring 220 ensures that the friction plate 206 is always in close contact with the edge banding 203. The friction plate 206 continuously pulls the edge banding 203 out of the strip tube 204, causing the strip tube 204 to adhere to the side of the sheet. Simultaneously, the laser generator 110 emits laser light, which, in conjunction with the scattering mirror 111 and the reflector 112, directs the laser light onto the extended strip tube 204, causing the strip tube 204 to laser-band the side of the sheet. The cutting cylinder 222 extends, and the cutting blade 223 severs the strip tube 204. When the sliding frame 120 moves outward, it drives the sliding block 221 to slide outward along the intermediate frame 201. The position of the sliding block 221 is adjusted to match the width of the sheet. As the sliding block 221 and the winding drum 202 move outward, the movable gear 209, in conjunction with the limit plate 215, drives the sliding block 221 to slide along the grooved rotating rod 210, with the sliding gear 211 and the movable gear 209 always meshing.When the edge banding of the plate is completed, it continues to move forward and reaches the rear conveying roller 304. The rear conveying motor 302 rotates to drive the rear gear 303 to rotate, thereby driving the rear roller gear 305 to rotate, and through the rear transmission belt 322, all the rear roller gears 305 and the rear conveying roller 304 are driven to rotate. The rear conveying roller 304 conveys the plate. When the plate contacts the upper arc plate 308, the upper arc plate 308 and the cutter 310 are lifted up, and the compression spring 309 is compressed, so that the cutter 310 is in contact with the upper surface of the plate. In coordination with the advancement of the plate, the excess part of the edge banding strip is cut off by the cutter 310. The movement of the bottom transmission belt 307 drives the toggle plate 320 and the reset rod 306 to slide through the pushing column 319, thereby driving the slide 312 and the lower pressure block 311 to move forward together, the slide spring 314 is stretched, the slide 312 pushes the rotating block 317 to rotate, and the rotating block torsion spring 318 is twisted. When the slide 312 passes the rotating block 317, the rotating block torsion spring 318 rebounds, and the cooperation of the rotating block 317 and the limit frame 315 makes the slide 312 unable to retreat. Since only the rotation of the front synchronous roller 122 can drive the bottom transmission belt 307 to move forward, the distance the lower pressure block 311 moves forward is consistent with the length of the plate; when the plate moves to the lower pressure block 311, the plate presses the lower pressure block 311 down, and the lower pressure spring 313 After the cam 314 is lifted up, the cam 315 is lifted up and the support frame 310 is in the upright position, and the cam 316 is in the upright position, so that the cam 314 can be lifted up and the support frame 310 is in the upright position.
