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 20-25l, diameter 200-300mm, height 150-480mm.
2. Working process of full-automatic neck-in drum production line:
First place cutting cans body material in the resistance welding machine automatically picking place, Suck by the vacuum sucker to the feeding roller, through the feed roller to the deflection roller bending processing, then roll into the forming device into cylindrical body, body is fed into the resistance welding machine, after the accurate positioning for resistance welding. After welding, the cans body is automatically fed into the frame of the coating machine. There are two schemes of spraying type and rolling coating type, which are available for users to choose. It is mainly used to prevent the welding seam line from contacting air and causing rust. The cans body is transferred to the neck-in drum combination machine, and the cans body is in an upright state through the vertical device, and the screw rod reciprocates. The first operation is the cans body expansion. When the cans is in position, the cans tray is controlled by a servo motor and the tank is sent to the expansion cone mold. Step 2 turn up and down. If the bottom cover is required to make 7 layers, the third step can be carried out and the flanging amount can be further increased at the bottom. The upper die is fixed on the body, and the lower die is installed on the CAM to complete the upper and lower flanging when the CAM is jacked up. The fourth step is beading. After completing the above four steps, the conveyor belt will send the cans to the cover of the sealing machine. Conveying to the turn over device to change the direction of the lower part of the cans body, and then carry out the automatic induction of the Lid feeder and sealing 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.
6. Application industry
This production line is applicable to the production of metal round cans for food, medicine, chemical industry, paint, cooking oil and other industries. It can also be applied to the production of food cans, paint cans, edible oil cans, paint cans, lubricating oil cans, etc.
7. Applicable countries and regions
Applicable to countries or regions where labor is difficult, unstable, or highly paid. For example: Malaysia, Indonesia, Philippines, Vietnam, Thailand, India, dubai and so on.
Applicable to countries or regions with high output and high product quality. For example: Saudi Arabia, dubai, Russia, Canada, South Korea, Turkey and so on..
