Abstract

The invention belongs to the technical field of zipper packaging, and particularly relates to an opening expanding device of a zipper packaging machine. The opening expanding device comprises a support connected onto a machine body, and the support is provided with an expanding mechanism sleeved into a packaging bag and a positioning mechanism for limiting the position of the expanding mechanism;the positioning mechanism comprises an upper positioning piece and a lower positioning piece which are distributed up and down, a moving space is defined between the upper positioning piece and the lower positioning piece, the expanding mechanism comprises a connecting rod capable of moving front and back in the moving space, and the two ends of the connecting rod extend out of the moving space and are connected with a first limiting piece and a second limiting piece which can abut against one end of the upper positioning piece and one end of the lower positioning piece; and the first limitingpiece and the second limiting piece can move front and back relative to the upper positioning piece and the lower positioning piece, and the first limiting piece is connected with a bag opening platewhich is arranged in an opening mode. By means of the opening expanding device, the zipper packaging machine can open a packaging bag and continuously convey the packaging bag, meanwhile, the packaging bag can be protected, and the packaging bag is prevented from being damaged due to pulling.

Description

technical field [0001] The invention belongs to the technical field of zipper packaging, and relates to a mouth opening device of a zipper packaging machine. Background technique [0002] After the existing zipper is produced and processed, it can be packaged uniformly by mechanical equipment. During the packaging process, the equipment must first open the mouth of the packaging bag, so that the zipper can be loaded into the packaging bag in the follow-up work. Therefore, a device that can realize the effect of supporting the mouth is indispensable in the packaging equipment. [0003] While the opening opening device in the existing equipment is opening the mouth of the packaging bag, it also needs to convey the packaging bag at the rear end so that the packaging bag can pass through the device continuously, thereby realizing automatic opening of the packaging bag. In the stretching device, the unstretched part of the packaging bag is usually conveyed in a compressed state...
