Ironing, splicing and slitting device for preparing three-dimensional bag body

Abstract

The invention discloses an ironing, splicing and slitting device for preparing a three-dimensional bag body. The ironing, splicing and slitting device is characterized by comprising a frame body, an ironing and splicing mechanism and a slitting mechanism, wherein the ironing and splicing mechanism and the slitting mechanism are sequentially installed on the frame body; the ironing and splicing mechanism comprises a left ironing knife component and a right ironing knife component which are arranged in parallel, each of the left ironing knife component and the right ironing knife component comprises an upper ironing knife group, a lower ironing knife group and a driving part for driving the upper ironing knife group and / or the lower ironing knife group to move, and a film ironing and splicing channel is formed between the upper ironing knife group and the lower ironing knife group; and the slitting mechanism comprises a cutter, and the cutter is located between the left ironing knife component and the right ironing knife component. According to the device, films which are overlapped up and down are subjected to ironing, splicing and slitting to form the left side edge and the right side edge of the three-dimensional bag body, so that the three-dimensional bag body is convenient to prepare.

Description

technical field [0001] The invention relates to the field of bag making, in particular to an ironing and cutting device for preparing three-dimensional bags. Background technique [0002] Bag making machine is a kind of equipment used to make packaging bags. The plastic film is divided into upper film and lower film, which are guided and conveyed separately, and then overlapped at a suitable position. The overlapped upper film and lower film are edge-sealed horizontally and vertically. Finally, a plurality of bag structures are formed, and finally it is cut with a cutter to form a plurality of bags. [0003] Due to the limitation of the structure, the bag making machine in the prior art can only prepare flat film bags, but cannot prepare three-dimensional bags. However, with the continuous development of society, flat bags cannot meet people's storage needs in many cases. Therefore, there is an urgent need for a device capable of preparing three-dimensional bags on the mark...
