- What Is Bag Opening Machinery?
Bag-opening machinery is used to open sealed bags. They are often used to store the extracted contents in silos or as a pre-process for feeding components into production lines.
Bag opening machinery can be used in a wide variety of bags, including paper bags, plastic bags, polyethylene laminated bags, PP cloth bags, single-layered bags, and multi-layered bags.
Bag-opening machinery saves labor by using machines to open bags that were previously opened manually. They also help to prevent contamination of the contents with dust and other contaminants.
The efficient collection and disposal of used bags is another reason for the introduction of bag-opening machinery.
Uses of Bag Opening Machinery
Bag-opening machinery is used in the construction and civil engineering fields to open bags for ready-mixed concrete, secondary concrete products, drive mix, and additives.
Bag-opening machinery is also used in the food industry to open bags of raw materials, and in the agricultural, dairy, and fishery industries to open bags for feed additives delivered to production sites.
In heavy industry, bag-opening machinery is also used for cement, lime, processed mineral products, and various additives.
Bag-opening machinery is manufactured to meet the needs of these various fields and types of packaging.
Features of Bag Opening Machinery
Bag-opening machinery is used in a series of processes, including conveying the bags to be opened, feeding the bags into the bag-opening machinery, opening the bags and dispensing the contents, and discharging and processing empty bags.
Bag-opening machinery includes bags of various materials as well as large-volume bags called flexible container packs, and machines have been manufactured that automate the entire process from loading to final processing with a view to full automation.
The cutter used to cut the bags, which is the main process of bag opening machinery, is selected to best suit the application.
In addition, bag opening machinery for powders and granules is manufactured with various innovations, such as “blowing out” using high-pressure air or “beating” using nozzles, so that as little of the contents as possible remain in the bag when the contents are discharged.
Furthermore, some bag-opening machinery is structurally designed to shield the contents from the surrounding environment to prevent dust and foreign matter from getting mixed in.
Others are designed to facilitate the collection of bags after the contents have been discharged.
