Tinplate aerosol can production line

1. Automatic cutting machine PTGS-2 (AUTO DUPLEX GANG SLITTER).

Automatic cutting system consists of an automatic sheet feeder, two scissors blocks: horizontal and vertical, double working table, electric control unit, vacuum system, equipment for feeder table, automatic pneumatic sheet-laying table and grinding machine. The line is equipped with automatic feed, automatic cutting, double sheet detection, automatic counting system. A choice is possible between carbide and alloy knives.

The first and second sheets are fed to the knives using two chains with leading teeth. The sheet position is adjusted on two sides.

The pairs of chrome and rubberized shafts move the sheets from the first scissors to the second ones. Shafts and electromagnetic beams are equipped with a pneumatic lifting system for adjusting the cutting of the first scissors.

The sheet positioning at the first scissors table is performed by small shafts by shifting the sheet to the right or to the left. The shafts are located on the runners of the axis of the ball bearing and are controlled by mechanical cams. The rear direction is carried out with the help of rotating stoppers, which can be adjusted during scissors operation (which allows to avoid production interruption when setting up). In this case, the sheet is cut exactly as it enters the print margins.

Feeding the sheet is done using auxiliary shafts with bearings for more convenient stacking.

2. Automatic aerosol can body welder

The machine consists of a pile-puller, a rolling machine, a transporter of shells and a welding device with a lower trunk.

The machine takes the sheets from the stack using a block of suction cups and a pushing pin. A separate sheet is pushed into the electronically specified time moment of the working stroke between the transport rollers by means of a collision pin. After passing through the control of the double sheet and the flexor, the sheet is fed into the rounding device, where it is rounded. If a double sheet is detected, the machine stops and a message is displayed on the display. In this case, the sheets must be manually extracted from the clotting station. The collapsed shell is received by the latches of the rotor and pushed between the welding rollers. On the welding rollers is placed a copper wire, used as an intermediate electrode. The welding current remains switched on throughout the working stroke, including between the welds. The contact rails and the lower trunk are protected by intensive water cooling.

3. Chiller with water cooling (WATER CHILLER).

The installation of the cooling of the blanks after the drying oven for lacquer with sufficient cooling capacity to reduce the temperature of the blanks to the required in terms of labor protection and safety of production.

4. Internal and external lacquering machine (optional)

Machine for applying varnish to the inner and outer part of the welded joint of the cylinder blank.

5. Gas oven upon request.

It consists of a belt conveyor with a bottom arrangement of magnets and three induction modules. A ventilation cooling system is used, without the use of chilled water. Each burner dries from 45 to 50 cylinder blanks per minute, depending on the height and diameter. When stopping the welding of the cylinder body during the previous stage or when the induction furnace is interrupted, all the cylinder casings left on the tape will be dried by a special induction system without the need to remove the cylinders from the conveyor.

8. Tester of tightness of the finished cylinder.

(AUTO HIGH PRESSURE LEAK TESTER)

Testing is done in a sequence of several stages. The cylinder is closed by an airtight hood that simultaneously covers the top opening of the cylinder. Compressed air with a pressure of 15 bar is sent to the cylinder. If the pressure gauge detects less pressure in the bottle, it is automatically rejected. The chamber between the balloon and the cap is evacuated. The first reading of the vacuum reading is performed. Near the output sprocket, the second reading of the vacuum reading is performed. The test result depends on the difference between the initial and final pressures.

The incoming cylinders are guided by the feeding conveyor and captured by the feeding star. In the event of any malfunction in the capture or release of the balloon, the conveyor immediately stops. The feeding star passes the cylinders to the central star, where the balloon is covered with an airtight hood and an overpressure inside the cylinder and a vacuum in the space between the hood and the balloon are created. Immediately after this, the pressure readings in the cylinder are read. The second reading is done near the output star. If the cylinder is not leaking, it is captured by an electromagnet and thrown into the rejection tray. Quality cylinders are sent to the exit of the machine.
