Further:
the cover box is a square cover box with an opening at the lower part, and one end of the square cover box is fixed on the fixing plate.
One end of the bag closing driving cylinder is hinged in the cover box, a bulge is arranged above one swing arm, and the other end of the bag closing driving cylinder is hinged with the bulge.
The bag closing clamp plate is a vertical plate, the lower end of the swing arm is provided with a fixing hole, a transverse waist-shaped hole is formed in the bag closing clamp plate corresponding to the fixing hole, and the bag closing clamp plate penetrates through the waist-shaped hole through a fastener to be matched and fixedly connected with the fixing hole.
The fixing plate is fixed on the top of the supporting frame.
Compared with the prior art, the utility model has the following advantages:
the bag opening closing mechanism is reasonable in structural design, and the middle part of the bag edge is internally folded by inwards moving a pair of bag closing clamping plates which are oppositely arranged, so that the M-shaped packaging bag opening is ensured to have a good bag closing effect; and compact structure, operating efficiency is high.
