The invention discloses a production technology for producing specially-shaped packaging bags, belongs to the technical field of packaging bag production, and solves the problems that in the prior art, in the production process of the specially-shaped packaging bags, the number of heat sealing edges is large, the production cost is high and the sealing effect is poor. The technology comprises the following steps that S1, film supply is conducted, specifically, a film material for processing the packaging bags is provided; S2, folding is conducted, specifically, the film material is folded along a center line through a folding mechanism; S3, transverse sealing is conducted, specifically, the folded packaging bags are subjected to heat sealing through a transverse sealing mechanism; S4, shaping is conducted, specifically, the surfaces of the heat-sealed packaging bags are made to be flat through a shaping machine; S5, die cutting is conducted, specifically, the packaging bags are machined into corresponding shapes through a specially-shaped die cutting device; S6, edge cutting is conducted, specifically, redundant film materials of the packaging bags are cut off; and S7, packaging is conducted. The folding mechanism is arranged, only transverse sealing is needed, longitudinal sealing is not needed, one heat sealing procedure can be omitted, the technology is simpler, the sealing performance is better, the energy consumption is reduced, and the production cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of packaging bag production, and in particular relates to a production process for producing special-shaped packaging bags. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production, the mechanized bag making machine has gradually become a product needed by the packaging bag manufacturing industry. In the processing and production of various plastic film packaging bags, two single sheets are generally heat-sealed and laminated to make a packaging bag to meet the needs of production and customers. In order to meet the needs of packaging effects, many bags need to be made into round bottoms or cut off two corners of the bottom to make corner-cut bags, or made into other special-shaped packaging bags. [0003] At present, special...
