Abstract

The invention belongs to the technical field of bag making production lines, and provides a novel block bottom valve bag making machine. The novel block bottom valve bag making machine comprises a conveying table, two bag pressing strips which are parallel to each other are arranged on the conveying table in a rotating mode, two opening and angle pressing mechanisms are arranged above the conveying table in parallel, wherein each opening and angle pressing mechanism comprises two negative pressure bag opening grippers and an angle pressing device, the two negative pressure bag opening grippersare used for expanding and opening a bag opening with the end portions folded, angle lifting vertical plates used for folding the two ends of a block bottom valve bag are arranged on the outer sidesof the negative pressure bag opening grippers, the angle lifting vertical plates are vertically and fixedly arranged on the conveying table, the angle pressing device is arranged on the sides, far away from the angle lifting vertical plates, of the negative pressure bag opening grippers, the angle pressing device comprises a conveying belt, the conveying belt rotates above the conveying table, twopressing feet are vertically and fixedly arranged on the conveying belt, and the pressing feet press the expanded and opened bag opening after rotating along with the conveying belt. Through the above technical scheme, the problem that in the prior art, a bag making machine is complex in method and structure for opening and shaping two ends of a base bag is solved.

Description

Technical field [0001] The invention belongs to the technical field of bag making production lines, and relates to a novel square bottom valve bag making machine. Background technique [0002] The square bottom valve bag is a small bulk packaging container, convenient, clean, and good in sealing. It is currently one of the most popular packaging materials in the world, and is especially suitable for export packaging. The existing square-bottom valve-mouth bag making machine generally uses a cylinder to drive the pressure plate to move up and down to shape the opened bag mouth after both ends of the base bag are sucked open by negative pressure. This method has a complicated structure and high energy consumption. And long-term damage to the work platform. Summary of the invention [0003] The present invention provides a new type of square bottom valve bag making machine, which solves the problems in the prior art. [0004] The technical scheme of the present invention is realized ...
