Title
Automated Fuse Making and Cutting Machine for Fireworks. Field of invention
The present invention belongs to the field of producing machine made fuse in fireworks. The invention relates more specifically to make fuse by machines. Which eliminate manual fuse making process and skin problems of hazardous chemicals. Particularly the invention make large quantity of production and different output in single machine and avoid skin problems of workers.
Background of invention
Generally the fuse making is manual in fireworks industry. They made fuse using their hands. It will lead to human beings be contact with Chemicals. Sometimes the fire accident may cause due to Friction. Objective of this project is to evaluate the safety characteristics of fuses which are made both manually and mechanically and to minimize the time and work load of workers for making quick match by fabrication of machine. Mechanism involved in this fuse making machine is V-belt pulley and Worm gear mechanism. Worm gear is used to reduce the speed of the motor from 1440 rpm to 85 rpm and also to transmit power from motor to the shaft. V-belt is used in this machine for attaining both clockwise and anticlockwise in circular disc.
Automation of operations in fireworks industries is a difficult task and extreme care must be taken if any attempt is made to automate because, it poses danger of explosion that leads to disaster. Manual operation poses health problems to workers. Fireworks industries manifest, vigilant techniques that minimises human intervention in various operations is highly demanded. Present invention is directed toward such a technique.
The fuse winding machine manages the production quality and quantity with safety at almost concern. Since direct working of labour onto the gunpowder is completely avoided disable the problems that are faced on traditional fuse making. Our proposed model decreases the usage of man power and thus increases the production rate. Workers skin damage because of fire work chemicals is entirely eliminated. Since the workers are not indulged to -„ chemicals directly-with their Jiands and any, otherrbody, parts are not-exposed to it. Since no

hand work is involved the quality of fuse wire is maintained to its entire length. This is economical operation since it uses very less man power and man wages. This can be implied on large scale industry concerning mass production over a little period. Since this is completely Power driven machine it does not require any man power for making fuse. Only man power is require for cutting the fuse.
Summary of the invention
The method and system of invention uses an electric motor for automation and it increases the production of fuse. It consists of motor, circular wooden disc, with bobbin rods. In this machine, the motor rotates the main shaft using worm gear. The shaft that rotates the circular wooden disc by using V-Belt drive. The resultant fuse in this machine consists of three layers. First layer is a main thread which is coming a main thread holder and it is dipped into the gunpowder which is located in the funnel. The gun powder in the funnel is in moisture condition for preventing friction, stickiness of gun powder in main thread.
The second layer in this fuse is made using first storey bobbin threads which is located in circular wooden disc. The first storey wooden disc rotated in clockwise direction to prevent wastage of gun powder and it consists of 18 bobbin threads for twisting.
The third layer in this fuse is formed in second storey circular wooden disc and it provide tightness for the fuse and the resultant fuse is feed by the feeder and it cut into required length using the Cutter which is made by Brass. Brass having higher frictional resistance.

Detailed description of the invention
Fig. 1 shows schematic view of the present invention in an assembled state. Rotating drive consists of an electrical motor (11) and worm gear mechanism (10). It is configured to be attached to the stand using clamps. Power transmission from rotating drive to shaft is effected using pulleys (08) and belt drive (06). Funnel contains visco state gun powder. The main thread from main thread holder (01) is feed into the funnel (02). The gun powder coated main thread is feed into the first storey of circular disc. The first storey of the circular disc rotating in clockwise direction at 82 rpm. Circular disc contains 12 number of bobbins in its outer diameter and 6 number of bobbins in inner diameter. Due to the rotation of circular disc, the bobbin threads are wound around the main thread. This process prevent the spill out of main thread gun powder. Then the first storey output is feed into the second storey circular disc. The second storey circular disc rotates in anti-clockwise direction at 82 rpm influence of cross belt. The second storey circular disc also contains same structure like first storey of circular disc. The second storey bobbin threads are wound around the first storey output. This process provides the grip ness to the first storey output. Then the second storey output is feed by feeder pulley. Cutting mechanism is provided to cut the fuse at required length.
