The bulk materials of finished goods in chemical industry have a great variety and vary in material feature, packing material and sealing way. For example, the common materials in chemical fertilizer industry alone include urea, compound fertilizer, diammonium phosphate, monoammonium phosphate, ammonium nitrate, ammonium sulfate, potassium chloride and potassium sulfate etc. In terms of material feeding way alone, it involves gravity type, screw type, belt type and electric vibration type etc. Moreover, corrosion resistance of the equipment, aided flowing of materials and other details shall also been taken into account. Those complex factors are liable to make the equipment unable to run optimally, even causing its failure to operate normally.

　　Besides, most of users control the packing cost strictly, usually resulting in use of low-cost soft bags for packing the finished goods. If conventional hemming type folding machine is used for folding and stitching the bags, it is likely to operate unstably; if automatic bag attaching machine of general structure is used, it cannot meet the normal need of continuous operation due to low efficiency of bag attaching.
