A high-speed automatic paper bag machine and its fully automatic bag-making method

Abstract

The invention discloses an automatic high-speed paper bag machine and a full-automatic bag making method thereof. The paper bag machine comprises a paper feeding part, a paper bucket adhesive part, a bag bottom opening part, a bottom folding part and a bottom sealing part, which are sequentially connected with one another; the bag bottom opening part is used for unfolding a first surface bottom, a first side bottom, a second surface bottom and a second side bottom in four directions, which form the bag bottom, on one end of the paper bucket; the bottom folding part is used for folding the first side bottom and the second side bottom inwards and then folding the first surface bottom inwards; the bottom sealing part is used for applying adhesive onto the first surface bottom or the second surface bottom and folding the second surface bottom inwards, so that the second surface bottom is bonded with the first surface bottom to seal the bag bottom of the paper bag. By adopting the automatic high-speed paper bag machine and the full-automatic paper making method thereof, the automatic high-speed paper bag machine not only comprises the paper feeding part and the paper bucket adhesive part, but also comprises the bag bottom opening part, the bottom folding part and the bottom sealing part, a paper bag die-cut sample can automatically form the paper bag after passing through the automatic high-speed paper bag machine, so that not only can the production efficiency be greatly increased, but also the overall production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of post-press processing of paper products, in particular to a high-speed automatic paper bag machine and a fully automatic bag-making method thereof. Background technique [0002] Paper bags are common items in people's daily life. Many commodities are sold with exquisite paper bags. Paper bags can even affect people's shopping decisions, so the importance of paper bags to commodities is self-evident. To make paper bags, it is generally necessary to die-cut and indent the printed paper to form a paper bag die-cut sample. This step generally requires the use of a die-cutting machine. The die-cut paper bag samples need to be folded and glued according to the preset creases and cuts to form paper bags. [0003] Existing paper bag die-cut samples such as figure 1 As shown, generally all include: first surface 1, first side 2, second surface 3 and second side 4, first surface bottom 5, first side bottom 6, sec...

AI Technical Summary

Problems solved by technology

In the existing paper bag die-cutting, the ordinary paper bag folder gluer can only bond the adhesive sheet 9 and the second side 4 to form a tubular paper drum, and manual operation is required in the later stage to form the paper bag.

In addition to rising labor costs will directly affect the production cost of the product; the more critical issue is that this production method leads to low production efficiency and it is difficult to meet the mass demand of customers

[0004] Recently, it has also been reported that advanced paper bag machines have appeared in foreign countries, and all processes can be completed by machinery. However, this kind of paper bag machine is very complicated and expensive, and the cost control of paper bag production is very critical, so it is difficult to promote this advanced paper bag machine in my country.

More importantly, this kind of paper bag machine can only be used for very thin paper bags, and it is difficult to apply to jammed paper with a certain thickness.

[0005] To sum up, at present, there is no paper bag machine that can automatically make paper bag die-cut samples into paper bags in China, especially there is no high-speed automatic paper bag machine that can automatically make paper bag die-cut samples made of thick cardboard. It is necessary to design such a high-speed automatic paper bag machine and its corresponding method of making paper bags
