Innovation of Belt machine at Thang Long Tobacco Company

Over the years, besides expanding tobacco market, The Thang Long Tobacco Company (Vinataba Thang Long) constantly innovating, improving the productivity of the machinery system, forming flexible production lines, bringing high efficiency in the production process.

Mr. Nguyen Hoang Hung-technical staff at Vinataba’s hard-work workshop is known for its initiatives to enhance the performance of machines in the workshops. At present, PX hard is using pillow pulley load-up tooth belt BKT ME7878 made of aluminium alloy. However, the design of this short ball drive, 2 bearings are closed close to each other, while the axis for fitting pulley makes the pulley away from the trap. The ear of the pillow to get into the slim bracket, the pillow mount is also aluminum alloy. With such a texture, after the working process, the tension of the Dai cord will make the pillow and the price bend, affecting the transmission of motion, resulting in the replacement of bearings and straps (about 3 months is to change the ball). This will result in less flexibility in production, as well as an impact on the maintenance costs and longevity of the equipment.

With his experience, Mr. Hung has redesigned the pillow and pulley shaft, changing the pillow material and the bracket, mourning the thickness of the ear getting pillow, pushing the distance 2 bearings away from each other. Making this improvement, the pulley will be located close to the trap, avoiding the big lipstick causing the knee to bend and damaging the bearings, straps and pulleys. This design not only applies to BKY ME7878 machines, but is also applicable to machines with a self-design structure.

After applying the improvement, the cluster pulley conveyor belts stable operation, achieving technical requirements, no longer the phenomenon of warping, not changing the ball regularly, the durability of the belt increases. Besides, reducing repair time, ensuring equipment productivity, easy assembly or fabrication. After the comparison, the timing of each amendment of this detailed cluster takes about 1 hours, 1 year the repair takes a total of 4 hours. Machine speed cover 350 covers/min (21,000 cover/h). Yield, 1 year Increase: 21,000 cover x 4h = 84,000 covers, profit 300 đ/cover, benefit: 84.000 x 300 = 25.2 million VND. Spare parts replacement (16 bearings, conveyor belts, pulley belts) of about 3 million VND. The total beneficial value of this initiative is up to approximately 28.2 million.
