MACHINE PARTS

Part 1 Reel Feeding Unit

  1. Reel feeding is equipped with an automatic hydraulic lifting function, now lifting heavy reels is ways easy and can be done with a push of button
    • Unwind using air shaft.
    • Heavy Brakes ensure great tension when required.
    • Automatic tension control system provides appropriate tension to the paper in the entire reel cycle.

2. Machine is equipped with automatic edge correction system, which help tube formation greatly and reduce wastage.

3. Automatic side glue dispensing system provides exact amount of glue required with respect of different quality of paper. It also ensures, dispensing exact amount of glue required with the speed of running paper.

Part 2 Printing unit

This is second part of the machine where the plain paper gets printed.

  1. The printing unit is equipped with high quality anilox to provide high quality of printing.
  2. Double nip attachment provides close loop of printing which make registration sharp.
  3. Long travel in compact design ensures quick dry of printing ink.
  4. Doctor blades assembly restrict excess ink to the paper, result sharp image formation.

Part 3 Paper bag forming unit

  1. This is this the unit where maximum operations is executed, starting with: Tube forming Side pasting Bag creasing Bottom opening Bottom Gluing Bottom closing
  2. Former unit has two servo motor which ensure right cutting. The cutting height can be changed automatically with the touch screen.
  3. The mechanical component used in former is high in quality which provides smooth performance with great stability
  4. The machine structure is heavy duty ensures high durability of machine working round the clock
  5. Auto detection electric sensors has been installed in the former unit which reduces breakdown

Part 4 Finished bag collection unit

The formed paper bags are pressed and conveyed out of the belt. The bag collecting unit receive the data from plc and can stack bag produced in desired quantity.

  • Automatic detection of electric eyes
  • Automatic counting photo eye

Part 5 Machine Electrical panel

The electrical panel of the machine can be named the brain of the machine in simple terms. It is equipped with best in class quality of components to deliver seamless work performance. It is also equipped safety devices which safeguards the machine from easily being damage. Component used in the machine are as follows. Automatic fault detection function

This function is mainly used when the machine is running in a normal high-speed state, if an unexpected situation occurs, the machine can be automatically stopped immediately to avoid unnecessary losses. This device is used in conjunction with the Japanese Yaskawa automation control system.

2. Automatic refueling system The system is mainly to automatically supply oil to the machine when it is running, to ensure that the gears of all parts of the machine are well lubricated, so that the machine can exert better performance under long-term operation

Part 6 Component coatings

  • The thickness of the shaft Hard chrome plating layer < .1 mm

Part 7 Others

Fastening screw materials UNBRAKO (USA)
Conveyor belt material PTG
Bearing SKF (Switzerland)
Pneumatic components JANATICS

Machine Advantages
