Nylon is a type of plastic made into thin sheets or bags and used often as transference sheets for water proof packaging. The ease of cutting and sealing a nylon material, especially during mass production of nylon bags, has necessitated automating the process. This paper develops an affordable and effective low-cost semi-automatic nylon cutting and sealing machine that can be utilized by small-scale businesses. The 900 400 350 mm machine comprises sealing and cutting filament, transformer with wires, teflon tape, micro switch, electric motor, transmission shaft, aluminum casing, mild steel stand and microcontroller. The components were optimized for durability, yet simple one operator use and portability for small-scale business settings. A transmission shaft size 25.4 mm in diameter and 850 mm in length is placed on the machine. The size of the shaft is selected according to the size of the electric motor. Structural analysis through testing validated the structural integrity of key parts. The yield stress was 380 N/mm2 and the safety factor was considered to be 2, so the working stress was 190 N/mm2 and the permissible shear stress was 100.71 N/mm2 . The performance testing showed that the prototype semi-automatic cutting and sealing machine has efficiency of 80% while cutting and sealing nylon at a rate of 700 bags per hour. These results confirm the machine’s ability to overcome the limitations of laborious manual methods through a continuous, high-output cutting and sealing process. Further, the machine is functional and possesses high performance efficiency with reasonable degree of accuracy.
Nylon is a robust substance, capable of withstanding temperature extremes, and is typically more cost-effective than many alternative plastic varieties. The first fractional electric motor cutting machine that could be mounted on a platform, which served as a cutting base, was developed by George Eastman. This machine also included a motor attached to a reciprocating knife mechanism. Automatic nylon sealing and cutting machine is used simultaneously to seal and cut nylon films into different sizes depending on the required number. Manual cutting and sealing of nylon films not only waste time but also increase cost of production, as more than required people are employed to a job that can be automated.
