Automatic neck-in drum production line
1. What is a neck-in drum?
It is made of three pieces of metal (mostly tinplate) : the body, the bottom and the lid of the cans. The cans is conical or cylindrical shape. The body of the cans has two ribs. The scope of closed barrel: capacity 10-25l, diameter 200-300mm, height 150-480mm.
2. Working process of full-automatic neck-in drum production line:
The production line is suitable for the automatic production of 10 liters to 25 liters’conical drum. total power: approx.100KW,total floor space: 250㎡ .total length:approx.36 meters. total manpower: 4-5 people. Production capacity: 28-30cpm. Drum height range: 170-460mm. Drum diameter range：200-300mm
Technical flow: cutting the tin sheet to blank—rounding—welding—inner and outer coating (inner powder coating and outer coating)—drying—cooling conveying—conical expanding-flanging-beading-bottom lid feeding-seaming-turning over-top lid feeding-seaming-leak testing-packaging
First place the cut can body materials into the automatic resistance welding machine’s feeding table, Suck by the vacuum suckers,send the tin blanks to the feeding roller one by one.through the feeding roller, the single tin blank is fed to the rounding roller to conduct rounding process, then it will be fed to the rounding forming mechanism to make rounding.The body is fed into the resistance welding machine and make welding after the accurate positioning. After welding, the can body is automatically fed into the rotary magnetic conveyor of the coating machine for outer coating, inner coating or inner powder coating, Which depends on customer’s various need.It is mainly used to prevent the side welding seam line from being exposed in air and rusting.The can body should be placed in induction drying oven to dry if it’s inner coating or inner powder coating.Afer drying, It will be fed to cooling device to make natural cooling.The cooled can body is then fed to the conical drum combination machine, and the can body is in an upright state going through the uprighting conveyor.The first operation is the can body conical expansion. When the can body is in position, on the can body lifting tray which is controlled by a servo motor, and the can body is sent by this lifting tray to the conical expanding mold to make conical expanding. Step 2 is upper and lower flanging.The step 3 is carried out if the bottom is required to make triple seaming,making the further more flanging amount of the bottom: The upper mold is fixed on the machine body, and the lower mold, which is mounted on the CAM, completes the upper and lower flanging when the CAM is jacked up. The step 4 is beading. After completing the above four steps, the conveyor belt will send the can body to the sealing machine. When the bottom lid auto feeder detects the can body coming, It will automatically feed one bottom lid to the top of the can body,and then both the can body and the bottom lid will be clamped to seaming machine head to make auto seaming.After bottom seaming, the can will be reversed up and down by reversing device,and then make top seaming,this process is the same as the bottom seaming process.Lastly,the finished can is fed by conveyor to automatic leak tester station.After accurate air source inspection, unqualified products are detected and pushed to a fixed area, and qualified products will come to the packaging workbench for the final packaging process.

4. Advantages and disadvantages of the full-automatic neck-in drum production line.
Advantages: the whole production line adopts automatic computer programming control system, fully realizing the full automatic assembly line work.Only 1-2 workers are needed to complete the operation of the entire production line.The whole production line has fast production speed, high production efficiency, automatic fault detection system and low rejection rate. Disadvantages: compared to semi-automatic production line, the initial investment capital is larger. For the start-up enterprises,It is recommended to use semi-automatic production line with less capital in.
5. Yixin products and peer products comparison
Yixin products: through professional design, the whole production line can achieve quick replacement of double seaming and triple seaming requirements, adjustable expanding rib mold, precise cooperation of imported guide rail and profile combined with servo motor, to ensure fast flow conveying system. Eight roller can sealing head and can sealing quality are stable and fast. At the same time, the sealing head is specially designed, which has the characteristics of low noise and high efficiency.
Products of the same industry: the whole production line can only achieve the production of double seaming or triple seaming. The expanding mould is fixed and can not be adjusted at will. Common profile and domestic track, combined with stepping motor coordination, lack of stability and accuracy. There are only four rollers in the head of the can sealer, so the quality and speed will have a certain impact. At the same time, the machine head adopts old-fashioned design, and the production noise is large.
