Abstract

The invention provides a bag bottom corner positioning and forming device and a packaging bag production line. The bag bottom corner positioning and forming device comprises a support, two positioning assemblies and a driving mechanism, wherein each positioning assembly comprises a driving chain wheel, a driven chain wheel, a transmission chain, a guide plate and a fork assembly; the driving chain wheel and the driven chain wheel are rotationally connected on the support; the transmission chain is wound on the driving chain wheel and the driven chain wheel; the guide plate is positioned between the driving chain wheel and the driven chain wheel; a protruding part is arranged on the guide plate; the fork assembly comprises two mounting bases and two forks; rotating shafts are arranged on the mounting bases; the rotating shafts are rotationally connected on the mounting bases; the forks are fixed on the corresponding rotating shafts; connecting rods are also fixedly connected onto the rotating shafts; rotatable pulleys are arranged on the connecting rods; the mounting bases are fixed on the transmission chain; the two positioning assemblies are oppositely arranged; the protruding parts on the two guide plates are also oppositely arranged; the driving mechanism is in driving connection with each driving chain wheel. The bag bottom corner positioning and forming device can position and form four corners at the bottom of a bag quickly and reliably.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a bag bottom four-corner positioning forming device and a packaging bag production line. Background technique [0002] At present, packaging bags (such as cement bags or fertilizer bags, etc.) are widely used in the packaging and transportation of materials. In the production process of the packaging bag production line, the fabric of the packaging bag is a double-layer structure and is wound into a cloth roll as a whole. After the cloth roll is unwrapped, the cloth is cut into a set size by the cloth cutting device and then transported to the opening mechanism at the bottom of the bag for processing. The opening of the bottom of the bag is processed, and then the opening is propped open by the support plate. The opened bottom of the bag needs subsequent bending treatment, and finally the bottom sealing operation. However, after the bottom of the bag is stretched, the opening of the bot...
