Automatic paper bag machine

Abstract

The invention discloses an automatic paper bag machine. The automatic paper bag machine comprises a stock bin, a barrel forming station, a bag side inward folding station, a bag bottom opening station, a bag bottom folding station, a steering station and a surface bottom folding station which are sequentially arranged on a rack according to the paper bag forming technological process, and furthercomprises a first aligning device, a bag opening reinforcing piece folding station, a reinforcing piece pressing station and a second aligning device. Firstly, a bag opening reinforcing piece is folded inwards and then conveyed to a subsequent barrel forming device through the second aligning device, a bag side is folded inwards and a bag bottom is formed, manufacturing of a paper bag can be completed at a time, through the effect of the second aligning device, smooth transition in the paper blank conveying direction is achieved while paper blank aligning is completed, and the advantages of being stable in performance, high in production efficiency and low in cost are achieved.

Description

technical field [0001] The invention relates to the technical field of paper bag forming machinery, in particular to an automatic paper bag machine. Background technique [0002] Due to its unique environmental protection properties, paper bags are widely used in the packaging of various commodities. At present, paper bags have basically realized mechanized production. According to the different types of paper blanks when producing paper bags, they are usually divided into roll-fed paper bag machines and sheet-fed paper bags. Machine, reel paper bag machine is suitable for the production of paper bags with relatively thin paper blanks, and the sheet-fed paper bag machine is suitable for the production of paper bags with relatively thick paper blanks (that is, commonly referred to as jammed paper); when using sheet-fed paper for paper bag production, Usually, the base paper should be die-cut and indented first to form a paper blank that conforms to the unfolded drawing of the...

[0002] Due to its unique environmental protection properties, paper bags are widely used in the packaging of various commodities. At present, paper bags have basically realized mechanized production. According to the different types of paper blanks when producing paper bags, they are usually divided into roll-fed paper bag machines and sheet-fed paper bags. Machine, reel paper bag machine is suitable for the production of paper bags with relatively thin paper blanks, and the sheet-fed paper bag machine is suitable for the production of paper bags with relatively thick paper blanks (that is, commonly referred to as jammed paper); when using sheet-fed paper for paper bag production, Usually, the base paper should be die-cut and indented first to form a paper blank that conforms to the unfolded drawing of the paper bag, so as to facilitate the subsequent paper bag machine to make paper bags, such as Figure 7 As shown, this type of paper blank usually includes a pocket reinforcement sheet 1, a first side sheet 2, a first side bottom sheet 3, a first face sheet 5, a first side bottom sheet 6, a second side sheet 7, and a second side bottom sheet 8 , the second surface sheet 9, the second surface sheet 10, the connecting sheet 11, the plug-in sheet 12, wherein, between the first side sheet 3 and the first sheet 6, between the first sheet 6 and the second sheet 8 gap 4 is die-cut between the second side bottom sheet 8 and the second side bottom sheet 10, and between the connecting sheet 11 and the inserting sheet 12; the sheet-fed paper bag machine in the prior art can only produce paper bags After completing the paper base into a tube and the bottom of the bag, it is not possible to directly fold the mouth reinforcement sheet 1 inward during the production process so that the mouth of the finished paper bag has two layers of paper. The mouth reinforcement piece 1 is folded inward, resulting in low production efficiency and high labor costs
