The key components of the bag making machine mainly include the following
Film unwinding device:
It is mainly composed of unwinding rack, magnetic powder brake, unwinding swing roller, unwinding roller and EPC (electronic position control) device.
It is responsible for feeding the raw film into the machine smoothly and continuously.
Forming device:
It is composed of forming plate, forming guide roller, forming rod, pressing roller, conical roller, pressing plate, etc.
It is the key device for folding the film into the required bag shape.
Heat sealing device:
It is composed of heat sealing knife, cooling knife, rubber table, silicone rubber plate, high temperature cloth, etc.
It is responsible for heating and sealing the bag mouth or bag body to ensure that the seal is firm.
Cutting device:
It is generally a scissor-type film cutting device, the upper knife is the action knife, and the lower knife is the fixed knife.
It is responsible for cutting continuous film bags into individual finished bags.
Tension control system:
It ensures that the film maintains appropriate tension during processing to avoid relaxation or excessive stretching.
Sensor and control system:
Responsible for monitoring the machine's operating status, such as temperature, pressure, speed, etc., and adjusting according to preset parameters.
The control system usually adopts a PLC programmable servo control system and a touch screen human-machine interface for easy operation and monitoring.
Cooling device:
Quickly cool the sealed bag to fix the seal and avoid deformation.
Conveyor belt:
Responsible for outputting the finished bags from the machine for easy collection and sorting.
In addition, depending on the specific type and configuration of the bag making machine, some other key components may also be included, such as automatic light-controlled feeding device, bag making length regulator, overrunning clutch, welding knife adjustment device, etc. These components play their own unique roles in the bag making process, and together ensure the efficient and stable operation of the bag making machine.
