However, in the chamfering process, part of the adhesive film is exposed to the outer edge of the plate, and the conical milling cutter 431 and the adhesive film rub against each other, so that the adhesive film is pulled, and the film coating quality on two sides of the plate is affected.

Therefore, in this embodiment, the first chamfer further includes: a fourth mounting seat 450 mounted on the output end of the lifting mechanism 420 and on the frame 100, a shredder wheel 451 arranged on the fourth mounting seat 450 and adapted to cut the film on the board, and a scraper 452 arranged between the shredder wheel 451 and the milling cutter and adapted to remove the film. When the traversing mechanism drives the third mounting seat 430 and the fourth mounting seat 450 to move to the other side of the plate, the paper shredding wheel 451 moves along the outer edge of the plate to shred the exposed adhesive film of the area to be cut, and then the adhesive film is removed through the scraper 452, so that the phenomenon that the adhesive film quality is influenced due to mutual friction between the conical milling cutter 431 and the adhesive film in the chamfering process is avoided; the sheet material is then chamfered or filleted by rotation of the taper mill 431 on the fourth mount 450.

The second chamfering unit 500 and the third chamfering unit 600 are respectively installed at both sides of the frame 100, and are adapted to chamfer both sides of a sheet material; the structures of the second chamfering unit 500 and the third chamfering unit 600 are the same as those of the first chamfering unit 400, and are not described herein again. It should be noted that the third mounting seats 430 of the second chamfering unit 500 and the third chamfering unit 600 always have a tendency of moving toward the center side of the plate, and after the plate is deviated, the adaptive mechanisms 440 on both sides can also push the plate to move toward the other side, so as to correct the deviation of the plate in time. Thereby avoiding the condition of 'knife clamping' caused by overlarge contact angle between the plate and the milling cutter of the chamfering device at one side and ensuring the production efficiency of the plate.

In addition, a second traverse mechanism 510 is disposed between the second chamfering unit 500 and the third chamfering unit 600, and the second traverse mechanism 510 includes an adjusting plate 511 and an adjusting rod 512 connected to the adjusting plate 511 for adjusting the distance between the second chamfering unit 500 and the third chamfering unit 600. By adjusting the distance between the second chamfering unit 500 and the third chamfering unit 600, the adaptability can be adjusted according to different specifications of the plate, and particularly, the effect is better when some products which are updated more quickly are processed.

In a further embodiment, a plurality of second pressing mechanisms 820 are disposed on the frame 100 between the first chamfering unit 400 and the fourth chamfering unit 700, and the second pressing mechanisms 820 include: two third cylinders 821 hinged on the upper part of the frame 100 and having a predetermined distance therebetween, a mounting plate 822 rotatably mounted on the frame 100 through pins 330, and a plurality of pressing wheels 823 arranged on the mounting plate 822 and moving along with the sheet material. Through setting up a plurality of second pushing mechanisms 820, guarantee remain the laminating state throughout between panel and the cylinder, guarantee that panel and toper milling cutter 431 are located the coplanar throughout on the one hand, on the other hand avoids panel to appear the spring at the chamfer in-process, takes place the skew, and then guarantees the chamfer precision of second chamfer unit 500 and third chamfer unit 600.

The fourth chamfering unit 700 is disposed on the rack 100 at an outlet end of the plate, can move along the vertical direction and the plate conveying direction through a traversing mechanism, and is suitable for chamfering the front side of the plate; the structure of the fourth chamfering unit 700 is the same as that of the first chamfering unit 400, and the installation direction is opposite, and the detailed structure is not described herein.

In addition, a guide unit 300 and a first pressing mechanism 810 are disposed at an outlet end of the fourth chamfering unit 700, and are respectively used for aligning and fixing the plate. The structure of the pilot unit 300 and the first pressing mechanism 810 located in front of the first chamfering unit 400 are the same, and further description is omitted here.

In order to ensure the smoothness of the plate and the environment for processing the plate, a dust suction device 460 is provided above the taper milling cutter 431 for sucking dust and debris flying during the chamfering process. A cleaning unit 900 is further disposed at the end of the fourth chamfering unit 700, and the cleaning unit 900 for cleaning includes: an air pipe 910 horizontally installed on the rack 100 and connected to an air source device, and a plurality of nozzles 920 disposed on the air pipe 910; the remnants adhered to the surface of the plate are removed by the high pressure gas sprayed from the nozzle 920.

In order to facilitate understanding of the technical scheme of the plate chamfering device and the chamfering method thereof, the working principle of the plate chamfering device is briefly explained: in the plate processing process, the plate is conveyed to the guiding unit 300 through the conveying unit 200, the front end surface of the plate is firstly contacted with one of the first baffle plates 340, and then continuously moves to be blocked by the two first side plates 443b, when the front end of the plate is blocked by the baffle plates on the two sides, namely the placing direction of the plate is consistent with the conveying direction, the pull rod 320 is pulled through the fourth cylinder 310, the baffle plates on the two sides are pulled down to be lower than the roller unit 210, the standard of the guiding unit 300 for the position of the plate is realized, and the front end surface of the plate is perpendicular to the conveying unit 200; then the conveying unit 200 suspends transportation, and the position of the plate is temporarily fixed through the first pressing mechanism 810, at this time, the first chamfering unit 400 is located on one side of the front end face of the plate, the two conical milling cutters 431 are forced to abut against the upper edge and the lower edge of the front end face of the plate through the self-adaptive mechanism 440, then the first chamfering unit 400 moves from one side to the other side of the front end face of the plate, the paper shredding wheel 451 moves along the outer edge of the plate to shred the exposed film of the area to be cut, and then the film is removed through the scraper 452, so that the phenomenon that the film quality is influenced due to mutual friction between the cutters and the film in the chamfering process is avoided; the tapered milling cutter 431 on the third mounting seat 430 rotates to chamfer the front end face of the plate;

then the first pressing mechanism 810 loosens the plate, the transmission unit 200 continues to move forwards, when two side faces of the plate respectively move to the second chamfering unit 500 and the third chamfering unit, the self-adaptive mechanism 440 forces the conical milling cutter 431 to respectively abut against the upper edge and the lower edge of the two side faces of the plate, then the plate continues to move, similarly, the exposed sticking film of the area to be cut is removed through the paper shredding wheel 451 and the scraper 452, and chamfering processing of the two side faces of the plate is realized through the conical milling cutter 431;

when the plate is detected to move to the outlet end, the transmission unit 200 moves reversely for a preset distance, the position of the plate is adjusted through the guiding mechanism until the rear end face of the plate is aligned with the fourth chamfering unit 700, the transmission unit 200 stops conveying, and the position of the plate is temporarily fixed through the first pressing assembly located at the outlet end; at this time, the fourth chamfering unit 700 is located at one side of the front end face of the plate, the two conical milling cutters 431 are forced to abut against the upper and lower edges of the rear end face of the plate through the adaptive mechanism 440, and then the fourth chamfering unit 700 moves from one side of the rear end face of the plate to the other side to chamfer the rear end face of the plate;

the conveying unit 200 continues to transport, and when the conveying unit passes through the cleaning unit 900, the nozzle 920 automatically sprays high-pressure gas to remove the scraps adhered to the surface of the plate, and then the plate is discharged.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.
