Non-woven packaging bag making forming and edge overturning device and making forming and edge overturning technology

Abstract

The invention relates to a non-woven packaging bag making forming and edge overturning device and a making forming and edge overturning technology. The device comprises a base plate, an inner supporting device, a main air cylinder, a pressing column, a clamping device and four edge overturning devices. The inner supporting device is installed on the base plate. The pressing column is arranged inside the inner supporting device. The main air cylinder is arranged between the lower end of the pressing column and the base plate in a connected manner. The four edge overturning devices are evenly installed on the base plate. The inner supporting device is located among the four edge overturning devices. Because during one-time manual mark pressing, mark pressing can usually be carried out on oneposition of non-woven, the efficiency is low; because the non-woven is soft in texture, when the non-woven is subjected to manual mark pressing in the state of being not taut, folding mark lines maybe irregular; and obvious folding mark lines cannot be easily formed with manual mark pressing on the non-woven, staff need to carry out mark pressing more than one time to form relatively obvious pressed marks, however, the positions of pressed marks of multiple times cannot be completely consistent easily; and with the non-woven packaging bag making forming and the edge overturning device and the making forming and edge overturning technology, the problems mentioned above can be solved.

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...

AI Technical Summary

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
