Sealing cutting mechanism for packaging bag processing

Abstract

The invention discloses a sealing cutting mechanism for packaging bag processing. The sealing cutting mechanism comprises a workbench and a feeding motor, wherein a horizontal sliding guide rail is arranged on the upper surface of the workbench; the upper surface of the horizontal sliding guide rail is connected with a movable bracket through a slide block; a lower knife rest is mounted on the right side surface of the movable bracket through a bolt; a perpendicular sliding guide rail is further arranged on the right side surface of the movable bracket; the right side of the perpendicular sliding guider ail is connected with the upper knife rest through a slide block; the right end of the upper knife rest is fixedly equipped with a crank; the tail end of the crank is connected with a driveend of a speed reducer; a fixed bracket is further arranged on the upper surface of the workbench; the feeding motor is arranged on the upper surface of the fixed bracket; and the left end of the feeding motor is connected with a floating sealing device through a lead screw nut. The sealing cutting mechanism can be used for cutting products of different materials and different shapes, so that theprocessing range of the sealing cutting mechanism is greatly increased; and a suspension sealing device is used, so that sealing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of packaging bag cutting, in particular to a sealing and cutting mechanism for packaging bag processing. Background technique [0002] Packaging bags are widely used in the packaging of electronic appliances, high-tech products, furniture and other products. Its packaging operation is simple and convenient, and it has good compressive and load-bearing properties. It can be used in conjunction with stretch film, packing tape, paper fumigation-free tray, etc. to realize the packaging and use of items. However, there are still certain defects in the production process of the packaging bag, which limits its development: [0003] (1) At present, most of the cutting machines for cutting the packaging bags to length on the market use the cutter to track the packaging bag to the cutting position, and then use the hydraulic pressure to drive the cutter to cut down to complete the cutting action. This kind of cuttin...

AI Technical Summary

Problems solved by technology

This kind of cutting machine is relatively bulky overall, the cost is high, the impact of the cutter on the guide rail is relatively large, and because the cutter needs a certain reciprocating stroke when tracking the feeding, the cutting length of the packaging bag cannot be controlled too short, which limits the cutting length of the packaging bag. the length range;

[0004] (2) The existing packaging bag sealing devices generally use hot pressing technology to sew them together, but because the uniformity of the pressing cannot be controlled, the sealing effect is not good, which limits the production of packaging bags
