The waste chips generated by cutting the plate of the present invention will fall onto the waste chip receiving inclined plate, and the waste chip receiving inclined plate will guide the waste chips into the spiral groove of the spiral automatic chip conveyor 139, and the spiral automatic chip conveyor 139 will then discharge the waste chips out of the trimming frame.

[0059] A left material guide plate 1375 is provided on the trimming frame 131 at a position corresponding to the left saw blade 1366 , and a right material guide plate 1376 is provided on the trimming sliding seat 1369 at a position corresponding to the right saw blade 1364 .

[0060] The working principle of the present invention is:

[0061] Before starting work, the worker inputs the size of the plate into the controller in advance, and the controller sends a signal to the trimming translation servo motor 1360. The trimming translation servo motor 1360 drives the trimming sliding seat 1369, the right saw disc knife 1364 and the right material guide plate to slide horizontally to control the distance between the left and right material guide plates 1375 and 1376 to correspond to the width of the plate, so that the left and right material guide plates 1375 and 1376 are aligned with the left and right sides of the plate.

[0062] When the present invention is working, the plate is transported from the composite production line to the feed support plate 132, and the pushing cylinders 1324 of the left and right pushing assemblies drive the pushing rotating rod 1325 to rotate downward, and the pushing rubber block 1327 at the lower end of the pushing rotating rod 1325 abuts against the plate, and the pushing rubber block 1327 pushes the plate to slide backward until one end surface of the plate abuts against the two positioning baffles 1352, and then the pushing cylinder 1324 of the middle pushing assembly drives the pushing rotating rod 1325 to rotate downward, and the pushing cylinder 1324 also pushes the plate backward again to adjust the position of the plate so that one end surface of the plate remains flush, thereby finally positioning the plate.

[0063] Then the baffle lifting cylinder 1354 drives the positioning baffle 1352 to descend, and the positioning baffle 1352 no longer blocks the sheet from being transported backward. Then the sheet traction motor 138 drives the middle traction roller group 134 to rotate, and the middle traction roller group 134 drives the front traction roller group 133 and the rear traction roller group 137 to rotate synchronously. At the same time, the two front downward pressure cylinders 1333 drive the front upper clamping roller 1331 to slide downward, the two middle downward pressure cylinders 1343 drive the rear middle upper clamping roller 1341 to slide downward, and the two rear downward pressure cylinders 1373 and 1374 drive the rear upper clamping roller 1371 to slide downward. The front upper clamping roller 1331 and the front lower clamping roller 1332 clamp the sheet up and down, and rotate to drive the sheet to be transported backward to the middle traction roller group 134, and the middle upper clamping roller 1341 and the middle lower clamping roller 1342 also clamp the sheet and transport it backward to the first trimming mechanism and the second trimming mechanism. When the double-sided cutting mechanism cuts the plate, the left side and the right side of the plate respectively rest against the left material guide plate 1375 and the right material guide plate 1376 and are transported backwards, and the left side and the right side of the cut plate are respectively guided and output by the left material guide plate 1375 and the right material guide plate 1376.

[0064] The left and right trimming motors drive their respective saw blades to rotate at high speed. The plate is slowly transported backwards under the rotation of multiple groups of traction rollers. The left and right saw blades begin to cut the side edges of the plate respectively. The cut side edges are guided out by the edge guide plates on both sides of the trimming frame 131. The trimmed plate is transported to the rear traction roller group 137. The rear traction roller group 137 continues to clamp the plate and output the trimmed plate backwards. During the cutting process of the left and right saw blades, the left industrial vacuum cleaner, the right industrial vacuum cleaner and the spiral automatic chip conveyor of the present invention are also started. The waste chips generated during the trimming process fall onto the waste chip receiving inclined plate. The waste chip receiving inclined plate guides the waste chips into the spiral groove of the spiral automatic chip conveyor, and then the spiral automatic chip conveyor discharges the trimming frame 131. The left and right industrial vacuum cleaners can also efficiently absorb dust to prevent dust from adhering to the surface of the plate or flying into the environment during cutting, which is not environmentally friendly.
