Transverse toughness detector for PET (polyethylene terephthalate) plastic steel band

The invention discloses a transverse toughness detector for a PET plastic steel band for cotton packing. The detector is characterized in that: a band driver is formed through connecting four same bended pressure heads, a long pressure rod and a lower pressure handle, two ends of the long pressure rod are fixedly connected with a piston case, the four bended pressure heads are uniformly distributed on the long pressure rod, a PET test stand is under the four bended pressure heads, and the lower pressure handle is movably connected with the long pressure rod; the PET test band is fixed on fivelower adjustment pressure heads, a pressure sensor is under the five lower adjustment pressure heads, and bottom parts of the five lower adjustment pressure heads uniformly distribute on a lower support from left to right; and the lower part of an upper support is provided with a parallel mechanism, an upper side and a lower side of five slider crank mechanisms are respectively connected with a long connecting rod at five
