Abstract

The invention discloses a triangular sheet folding assembly. According to the key point, the triangular sheet folding assembly comprises a left plate turning device, a right plate turning device, a left plate pressing device, a right plate pressing device and a wrapping tape positioning plate. The wrapping tape positioning plate is arranged in the front-back direction. The left plate turning device and the right plate turning device are symmetrically arranged on the left side and the right side of the wrapping tape positioning plate, the left plate turning device is used for folding a triangular sheet rightwards by 180 degrees, and the right plate turning device is used for folding the triangular sheet leftwards by 180 degrees. The left pressing plate device is fixedly arranged on the leftplate turning device and used for fixing the corresponding part of the left side of the triangular sheet and preventing the triangular sheet from scattering and deforming when folded leftwards. The right pressing plate device is fixedly arranged on the right plate turning device and used for fixing the corresponding part of the right side of the triangular sheet and preventing the triangular plate from scattering and deforming when folded rightwards.

Description
