Fully automatic paper bag making machine

Description

This fully automatic high-speed paper bag making machine is suitable for producing paper bags from all kinds of paper. The production process is as follows: perforating – centre gluing – print registration – tube forming – cut-off registration – bottom creasing – bottom folding – collection of the finished product. It is the ideal machine for plain paper bags or bags with a plastic window, as well as bakery bags, fruit bags, eco-friendly bags and many more.

Key features

●Lenz PLC - British TRIO PLC and high-speed optical fibre for high-speed, precise and stable machine control.

●Beckhoff servos - Three sets of servo motors and servo drives.

●Schneider electrical components - French SCHNEIDER low-voltage electrical components. They ensure long machine life and prevent instability at high speeds.

●Window patching - The machine can apply plastic windows in various positions, for example as a side window or a centre window. Optional air unwinding with a magnetic brake ensures smooth unwinding of the film at the required tension..

●Production counting - The machine includes an intelligent counting and marking system that counts the bags one by one – simply set the required quantity on the control panel. The last bag of each batch is pushed slightly out of line to mark the count. This makes collection easy and counting accurate, and also saves labour..

●Print registration control - Optional German SICK colour photoelectric tracking sensor. It ensures accuracy and alignment of the printed pattern. If any error occurs, the machine stops automatically. This significantly reduces waste..

●Material sensor - An infrared induction head automatically stops the machine when the material runs out or is damaged. Paper can be damaged as a result of machine malfunction; the infrared beam can detect this.

●Bottom folding accuracy - Optional German SICK photoelectric tracking sensor for increased sensitivity and precise folding of the bag bottom.

●Robatech hotmelt - Optional original Swiss Robatech hot-melt gluing system. It stands out for uninterrupted operation at low, medium and high speeds.

●Robatech glue nozzles - Optional original Swiss automatic glue gun. Glue flow is very easy to adjust. With the glue gun, there is no need to set the glue flow via hoses or provide heat protection.

●Choice of gluing method - There are two options for gluing the bag sides. The first is a glue gun: glue dosing is easy to control and glue is saved. The applied glue is always in the same line, and there is no glue clean-up. The second option is a traditional glue tank with applicator.

●Easy-to-maintain bottom gluing unit - Optional bottom gluing unit that is easy to dismantle. Glue output is easy to adjust to the size of the bag bottom.

●High-pressure glue tank - Optional Taiwanese high-pressure glue tank. It makes the gluing system easy to maintain and saves glue.

●Bag tube forming - Optional tube forming structure that allows adjustment from one or both sides of the tube. It reduces adjustment time and unnecessary waste.

●Bag pre-perforation - Optional servo motor for controlling the paper bag length. The paper is pre-perforated by a knife at high speed. Thanks to the high-quality rubber roller, the system has a long service life.

●Bag length control - Optional servo motor for controlling the paper bag length. The paper is gripped by a rubber roller rotating at high speed, ensuring a perfect, clean cut. Thanks to the high-quality rubber roller, the system has a long service life.

●Min. roll diameter setting - Optional roll diameter setting function. It triggers an alarm and stops the machine if the current roll diameter falls below the set minimum. This helps with timely roll replenishment and prevents excessive waste.

●Automatic roll loading - Optional automatic hydraulic lifting. The roll is loaded up and down automatically at the push of a button.

●Edge alignment sensor - Optional Italian SELECTRA EPC unit and ultrasonic sensor for edge alignment.

●Electrical cabinet cooling - Cooling unit for the electrical control cabinet. A strong guarantee for high-speed machine operation. It keeps the electrical components of the control cabinet at a constant temperature, significantly extending the service life of both the machine and its electrical components.
