Abstract

The invention discloses a forming method and device for brick-type bags, and belongs to the technical field of packaging. The forming method is characterized by comprising the following steps: a, rolling a film to be cylindrical; b, performing middle sealing through a middle sealing mechanism, and performing pin insertion on the bottom through a pin inserting mechanism; c, performing pre-clamping and sealed enclosure through a pre-clamping mechanism, adding materials into the cylindrical packaging bag through a feeding mechanism, and performing pin insertion on the upper end of the cylindrical packaging bag through a pin inserting mechanism; d, vacuumizing the packaging bag through a vacuumizing mechanism, pulling a material sliding plate back to the lower part of a forming cavity through a material sliding air cylinder; and enabling the packaging bag to be formed into the brick-type bag through the forming mechanism, sliding the brick-type bag which is already packaged out of the material sliding plate so as to finish a packaging period, and ensuring that the cycle makes continuous packaging.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a brick-shaped bag forming method and a forming device. Background technique [0002] With the advancement of industrialization, the application of material packaging machines is becoming more and more extensive. The most widely used material packaging machines are food packaging and paper towel packaging. When the material packaging machine packs paper towels, it can overlap the paper towels evenly and neatly stack them on the packaging film. Through end sealing and side sealing, it can output neat paper towel packages in large quantities. When the material packaging machine packs food, it can not only ensure the environmental protection and hygiene of food, but also greatly improve the packaging efficiency. [0003] Food packaging is an integral part of food commodities. Food packaging and food packaging boxes can protect food, prevent the damage of biological, chemical or...
