Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to a square edge banding production line. Background Art

[0002] At present, in the domestic and international edge banding and square sizing production lines, under the production process of connecting two machines in series, the long sides are edge banded in the first pass. Through transfer, after the workpieces in the first pass are rotated, the short sides are edge banded in the second pass. The transfer takes time, and when switching between edge banding the long sides and the short sides, the machine parameters need to be switched and adjusted, resulting in low efficiency. Under the production process of connecting four machines in series, the transfer process from edge banding the long sides to edge banding the short sides can be eliminated. However, when the speed of edge banding the long sides in the front is greater than the speed of edge banding the short sides in the back, when the aspect ratio of the workpieces approaches 1:1 at a certain time period, congestion will occur in the machine for edge banding the short sides in the back, causing the machine for edge banding the long sides in the front to stop, resulting in poor edge banding, and the maximum production capacity cannot be achieved.
