Detailed Product Description

This fully automatic machine unwinds plastic film from a flat roll and forms it into a tube which is then made into a bag before being filled with the product being bagged. The top of the filled bag is sealed while the bottom of the next bag is made.The machine includes:-Heavy duty folded steel frame, for hygiene and easy cleaning (stainless steel optional) Cup doser with screw doser, feeding belt and in-feed hopper Film reel support to hold 400mm diameter reel. Weighing unit with three scales Film reel unwinder device including a powered unwinder with integral film tensioning device. Bag forming tube, shaped to suit the clients filed bag size. Powered film unwinders at the sides of the forming tube, including two friction face, toothed belts  (Belt tensioning and friction is adjustable to suit film quality and filled bag weight) Pneumatic pressure compensation, of the toothed belts that feed film down. Encoder or photoelectric cell to control the film unwinding operation  see options (length and print pattern of the filled bag). (Photocell detects registration mark on film). Perforator to allow the expulsion of air once the bag has been filled  selectable function. The position of the perforator is fully adjustable in order to perforate the bag at a suitable place. Vertical sealing bar with anti-adhesive Teflon coating. (Double bars and entrained air venting system -price on request ) Horizontal welding bars, Teflon coated, and film cutter, having a perfectly synchronised hydraulic movement as the bars close and the film is cut. Cooling of the sealed zones (vertical and horizontal) by chilled air The air is cooled by a recirculating chilled water circuit  supply of refrigeration unit is included  this feature reduces the volume of air required and facilitates high speed bagging. One set of pneumatic controls. Motorised hydraulic powerpack for positive precise high speed movements. Electronic temperature controllers to monitor and adjust the temperature of the high speed impulse sealing bars. One electrical control panel with PLC controlled operating logic.
