This invention relates to a
sponge cutting and trimming
machine, comprising a conveying platform, a gantry frame, a ring blade mechanism, and a sliding mechanism including an upper sliding mechanism and a lower sliding mechanism. Each end of the upper sliding mechanism's
slide plate is mounted with a rotating wheel via a fixed plate, and the same applies to the lower sliding mechanism's
slide plate. The upper and lower sliding mechanisms are synchronously driven by the same motor. Torsion blade mechanisms are mounted on the left and right fixed plates of both the upper and lower sliding mechanisms. A
drive motor is mounted on the right fixed plate of the lower sliding mechanism, driving the rotating wheels connected to the right fixed plate. The ring blade winds around four rotating wheels and passes through the torsion blade mechanism. The advantages are that for
cutting and trimming rectangular sponges, only a 90-degree torsion blade reversal is needed, reducing blade twist and extending blade life; the torsion blade mechanism uses a cylinder to control the rotation of the torsion blade, which is simple and convenient.
