The Development of Cotton-Woolly Decompression Machine with Custom-made Raking Blade operated by Electrical Motor
In textile small-medium enterprises and micro companies that run a business of production and supplying mattresses, a synthetic cotton (cotton-woolly) is a better alternative instead of organic cotton in order to reduce the cost. However in certain conditions, the company needs to additionally process the cotton-woollies in order to get the fluffy property, suitable for mattress substance. A case study in NMH Production & Creation verified that the company managed to decompress only 20% of their per-day-capacity of mattress production (2-3 mattresses per-day) by using a modified cow-food crusher machine. A specific decompression machine; Cotton-Woolly Decompression Machine was proposed by Politeknik Kuala Terengganu researchers with custom-made raking blade and operated by 7.5hp electrical motor which estimated to been completely developed within six months. This machine is expected to daily produce 250 to 300 kg of processed cotton-woollies (10-15 mattresses per-day) which exceeds the company per-day requirement. The safety and efficiency of the machine were also been considered by including a closed-body frame to avoid direct contact to the blades and a control panel with labels in the design.
