AI Technical Summary

Technical Problem

In existing self-sealing stand-up pouch making machines, the cutting blade comes into contact with the worktable during the cutting process, causing wear on the worktable and affecting the cutting accuracy and quality of the packaging bags.

Method used

The cutting mechanism uses meshing gears to drive the cutting blade for cutting, avoiding direct friction between the cutting blade and the worktable. The dust removal mechanism removes dust and impurities from the material surface, ensuring tight sealing and good appearance quality.

Benefits of technology

It reduces equipment wear, improves cutting stability and precision, and ensures the cutting effect and finished product quality of self-sealing bags.

Abstract

The utility model discloses a kind of self-sealing three-dimensional bag efficient bag making machine, belong to bag making machine technical field, aiming at the problem that workbench is damaged and influences packaging bag cutting precision due to cutting knife long-term contact and strike workbench, including bag making machine main body, the utility model is set by setting cutting mechanism, opening drive motor drives one gear rotation, since two gears are engaged, so two gears reverse rotation simultaneously, make two first guide posts drive two connecting rods rotate simultaneously, under the action of two second arc-shaped guide slot, make two second guide posts drive two slides move towards, to drive two cutting knives to the self-sealing bag sent out by discharge port and cut, instead of traditional cutting blade drop and workbench extrusion to workpiece cutting, the movement of cutting knife does not involve direct friction with workbench, so the wear degree of machine is lower, less damage to equipment under long-term use, ensure that the cutting effect of self-sealing bag is more stable and accurate.
