Description

Technical Field

[0001] The utility model relates to the technology in the field of woodworking machinery furniture board processing, in particular to a longitudinal saw control system used for double-push-hand longitudinal and transverse cutting computerized board cutting equipment. Background Art

[0002] With the growth of furniture demand, panel cutting equipment has emerged; most of the current panel cutting equipment is controlled by a single system: that is, a controller interacts with a human-machine interface through serial communication to implement control. Panel cutting equipment includes longitudinal and transverse cutting computer panel cutting saw equipment. Longitudinal and transverse cutting computer panel cutting saw equipment can realize longitudinal and transverse cutting of panels. During the sawing process, due to the difference between longitudinal and transverse cutting, the longitudinal and transverse cutting computer panel cutting saw equipment needs to convert the longitudinal and transverse cutting processing directions, that is, the panels need to be turned to achieve the transition processing of longitudinal and transverse cutting. Existing longitudinal and transverse cutting computer panel cutting saw equipment usually includes a longitudinal sawing part and a transverse sawing part, wherein the longitudinal sawing part is used to realize the longitudinal cutting of the panels, but the longitudinal sawing part lacks a stop design for the panels, which makes it easy for the conveyed panels to be unable to be stopped during the longitudinal sawing process of the panels, resulting in the possibility of continuous feeding of the panels, resulting in the phenomenon of overlapping panels or mutual pushing of panels, resulting in the problem of affecting normal processing.
