Description

A gas exhaust hole manufacturing device for a sack

The present invention is a device for manufacturing a gas discharge hole for the packaging stand, in more detail, so that the gas discharge hole formed on one side of the packaging stand in order to discharge the gas generated in the interior of the various packaging to the outside to be continuously manufactured during the manufacture of the packaging stand. It relates to an apparatus for manufacturing a gas discharge hole for a package.

Typically, the packaging stand containing the contents of feed, fertilizer, compost, and various fermented foods generates various gases such as carbon dioxide gas after a certain period of time, which may cause the packaging stand to swell and burst. There was also a risk that can cause serious illness to the human body due to various harmful gases inside when opening the packaging to use.

In order to discharge the gas generated in the inside of the package to the outside of the package, Korean Patent Publication No. 20540 (published on March 10, 2003) and Registered Utility Model Publication No. 455097 (August 17, 2011) Vent holes and discharge holes are formed on one side of the pavement, as published in Japan, or as discharged to one side of the pavement, as published in Korean Utility Model Publication No. 439696 (announced April 28, 2008).

Therefore, it is difficult to form a gas discharge hole only on one side when the feed bag is a tubular packaging without a joint around the molding, and thus has a problem in that both holes are simultaneously drilled to form several unnecessary holes.

In order to form a gas discharge hole only on one surface of a tubular pavement without a junction around the perimeter, the synthetic resin is formed into a tubular pavement in a molding machine, folded and flattened on both sides, and a winding roll wound on a bobbin is supplied from a feeder. The individual openings of one side of the pavement cut during the cutting are cut by a sealing machine, and then the individual pavements are manually supplied one by one to a separate manual punching machine. Although the gas discharge hole was formed on one side of the package, the gas discharge hole was formed on one surface of the conventional tubular package, and after each punch was put into a separate punching machine by hand, the gas discharge hole was formed after punching. Removing and putting the new packaging back into the punching machine and repeating the punching. It takes a lot of work time, and the work efficiency is variable according to the skill of the worker, so highly skilled workers are required, which leads to a great waste of manpower, which leads to a significant decrease in work efficiency. It was extremely low, and when punching the gas discharge hole of the packaging box, the scrap (scrap) generated at this time enters the interior of the packaging box and caused a defect in the product, and thus had a number of problems.
