Die-cutting machine for producing single output standing pouches

Abstract

The invention discloses a die-cutting machine for producing single output standing pouches. When the single output standing pouches are produced, a film sequentially passes through a forming unit and a separation unit to perform die-cutting and separation on the standing pouches; mutual actions of a second floating roller, a tension regulating mechanism and a first floating roller enable the tensile force at two sides of generated film waste materials to be maintained consistent with the film drawing speed; the tension regulating mechanism controls a tension regulating roller to rotate and controls a tension regulating compression roller to enable the film waste materials to be tightly compressed with the tension regulating roller, so that the film waste materials winding on the second floating roller is tensioned, the second floating roller is lifted upward, and the first floating roller is correspondingly descended; accordingly the film generates no deviation when feeding is performed on the forming unit, the die-cutting procedure of the film is smoothly achieved, and then rolling the film waste materials through a rolling roller is achieved. The die-cutting machine for producing the single output standing pouches has the advantages of improving the processing quality of finished products of the single output standing pouches, reducing manual interference function on the film waste material rolling and reducing labor costs.

Description

【Technical field】 [0001] The invention relates to a die-cutting machine which can be used for producing single-out stand-up pouches. 【Background technique】 [0002] At present, the die-cutting machine has been widely used in the process of processing special-shaped bags after the bag-making process. Die-cutting machines generally pull the film waste on both sides to realize feeding and die-cutting. When the thickness of the film waste at both ends of the rewinding roller is uniform, the diameter of the film waste wrapped around the two ends of the rewinding roller is the same after winding, and the rewinding roller can tighten the two sides of the film waste to ensure the smooth die-cutting of the film. For the die-cutting of single-outlet stand-up pouches, the thickness of the film waste on both sides of the stand-up pouch is inconsistent: one side has two layers of film, and the other side has four layers of film. The diameters at both ends of the winding roller shaft are...

Problems solved by technology

For the die-cutting of single-outlet stand-up pouches, the thickness of the film waste on both sides of the stand-up pouch is inconsistent: one side has two layers of film, and the other side has four layers of film. The diameters at both ends of the winding roller shaft are inconsistent, resulting in inconsistent pulling speed of the film waste at both ends of the winding roller shaft and the pulling force on both sides, which causes the film to shift when feeding and die-cutting in the forming unit, affecting the self-supporting of the film die-cutting bag quality
