the work of the pneumatic bundling machine is mainly completed by three actions of tensioning, cutting and sealing, wherein the tensioning and the cutting are completed by a tensioning device, and the sealing is completed by a sealing device.

When the compressed air is supplied, the pneumatic motor and reducer assembly 14 starts to operate, the pneumatic motor and reducer assembly 14 sequentially transmits the motion to the worm 30 and the worm wheel 29 through the rotating bracket 34, the worm wheel 29 transmits the power to the worm wheel shaft 16 through the transmission block 27, and at this time, the tension wheel 17 connected to the worm wheel shaft 16 in a hexagonal shape starts to rotate to tension the steel belt 2. When the compressed air flowing into the air motor and reducer assembly 14 is cut off, the worm shaft 16 is locked against the reverse rotation by the driving block 27, and the binding band 2 pressed by the tension wheel 17 is still in a tightened state, at which time the steel band cutting operation is performed.

When the pneumatic bundling machine is used specifically, an air pipe is used for connecting an air source and the quick connector 13 at the tail part of the pneumatic bundling machine for tensioning the locking device, then the lock catch is buckled on the bundling belt, the bundling belt is wound around an object and then inserted into the lock catch, the buckling is carried out at the position 60-120 mm away from the lock catch, then the pneumatic motor and reducer assembly 14 is held, the handle 10 is pressed downwards by a thumb, a gap is formed between the tensioning wheel 17 and the backing wheel 1, a layer of bundling belt 2 is inserted into the gap between the tensioning wheel 17 and the backing wheel 1, the bundling belt 2 is placed between the support 6 and the cutter 3, and when the throttling valve of the tensioning device is rotated, the pneumatic motor and reducer assembly 14 starts to work, namely the bundling belt 2 is tensioned. When the strap passing through the lock is tightened to saturation, the tightening wheel 17 stops rotating, rotating the throttle valve of the tightening device in the opposite direction, cutting off the flow of compressed air through the quick connector 13 to the air motor and reducer assembly 14. At this time, under the action of the transmission block 27, the worm wheel shaft 16 is locked, the bundling belt 2 wound around the object is still in a tight state, at this time, the clamping jaws of the sealing device are placed on the lock catch, the valve handle is pressed upwards by fingers to seal, and after the sealing is finished, the valve handle is released, and the sealing device is removed. And finally, the tensioning device cuts off a layer of the bundling belt 2 and then removes the bundling belt.
