Problems solved by technology

[0004] Single manual creasing usually can only creasing one part of the non-woven fabric, the efficiency is low, and the non-woven fabric is soft, and the crease line may be uneven after manual creasing in the untightened state In addition, it is difficult to form obvious crease lines when indenting non-woven fabrics manually, and personnel need multiple indentations to obtain more obvious indentations. However, the positions of multiple indentations are difficult to be completely consistent, resulting in the final indentation Lines may be skewed

Abstract

The invention relates to a non-woven packaging bag forming and folding device and a forming and folding process, including a bottom plate, an inner support device, a main cylinder, an extrusion column, a clamping device and four folding devices. The bottom plate An internal support device is installed on the top, and an extrusion column is arranged inside the internal support device. A main cylinder is connected between the lower end of the extrusion column and the bottom plate. Four folding devices are evenly installed on the bottom plate, and the internal support device is located on four Between the hemming devices. The invention can solve the problem that usually only one place of non-woven fabric can be indented in a single artificial indentation, the efficiency is low, and the non-woven fabric is soft in texture, and creases may appear after artificial indentation in an untightened state. In the case of uneven crease lines, and it is difficult to form obvious crease lines when indenting non-woven fabrics manually, personnel need multiple indentations to obtain more obvious indentations. However, the positions of multiple indentations are difficult to be completely consistent. As a result, the final indentation line may be skewed and other problems.

Description

technical field [0001] The invention relates to the field of packaging bag production, in particular to a forming and folding device for non-woven packaging bags and a forming and folding process. Background technique [0002] Non-woven packaging bag is a kind of green product, tough and durable, beautiful in shape, good air permeability, reusable, washable, silk screen printing advertisements, shipping marks, long service life, suitable for any company and any industry as an advertisement and gift Use, which makes non-woven fabrics more and more popular in the market. [0003] In the process of making non-woven packaging bags, the cut non-woven fabric needs to be hemmed. The traditional hemming treatment is usually manual crease hemming. However, this hemming method often encounters some question: [0004] Single manual creasing usually can only creasing one part of the non-woven fabric, the efficiency is low, and the non-woven fabric is soft, and the crease line may be u...
