The utility model discloses pneumatic bundling machine moulds steel band loosening device's theory of operation as follows:

the utility model discloses can accomplish actions such as taut, cut off and vibration fusion welding, loosen plastic steel band. Wherein the tightening and loosening is performed by the bi-directional air motor assembly 3, the cutting is performed by the cylinder assembly 1, and the vibration welding is performed by the combination of the cylinder assembly 1 and the uni-directional air motor 27. After the main air inlet joint 30 of the pneumatic bundling machine is connected with an air source, the first channel 10 is always filled with compressed air, and the power and the movement of the tension wheel 24 are provided by the bidirectional air motor assembly 3 through the transmission of a worm and a worm gear.

When the tightening button 29 is pressed, compressed air sequentially passes through the air cylinder assembly 1, the second air pipe assembly 9 and the valve body 4 and then enters an air inlet of the bidirectional air motor assembly 3, the tightening wheel 24 rotates anticlockwise, and the plastic steel belt 17 starts to be tightened until the tightening wheel 24 does not rotate. When the tightening button 29 is released, under the tension of the plastic steel belt 17 and the self-locking action of the worm and worm gear transmission, the tightening wheel 24 tightly grips the plastic steel 17, and the plastic steel belt 17 between the pressing plate chuck 23 and the tightening wheel 24 is kept in a tightened state.

When the vibration and cut-off button 2 is pressed, compressed air enters the air inlet of the air cylinder assembly 1 and the one-way air motor 27, the vibrator and cutter combination 20 descends, and at the moment, the plastic steel belt 17 in the groove of the cutter frame 19 is cut off, and the overlapped double plastic steel belts are also subjected to vibration fusion welding.

After the vibratory fusion welding is finished, the handle 5 and the bidirectional pneumatic motor assembly 3 are held by the right hand, the valve rod 14 is pressed by the small thumb of the right hand, the valve rod 14 moves upwards to push the nylon ball 11, the first channel 10 is communicated with the second channel 16, compressed air enters the other air inlet of the bidirectional pneumatic motor assembly 3, the tensioning wheel 24 rotates clockwise to loosen the plastic steel belt 17, the pressing plate chuck 23 and the tensioning wheel 24 are opened at the moment, the valve rod 14 is loosened, the nylon ball 11 returns under the elastic force of the spring 8, the first channel 10 and the second channel 16 are cut off, the bidirectional pneumatic motor assembly 3 stops working, and therefore the pneumatic bundling machine can be smoothly pulled out from the space between the packing material 18 and the plastic steel belt 17. Exhaust gas formed during operation of the bi-directional air motor assembly 3 is exhausted through the exhaust port 32.

The specific application method is as follows:

the first step is as follows: connecting an air source with a main air inlet joint 30 of the pneumatic bundling machine by using an air pipe;

the second step: wrapping the packing material 18 by using the plastic steel belt 17, holding the overlapped part of the plastic steel belt 17 by the left hand, leaving the tail part of the plastic steel belt 17 at the lower part about 300 mm, and slightly pulling out the rest part of the plastic steel belt 17 at the upper part by the right hand;

the third step: the handle 5 and the bidirectional air motor assembly 3 are held by the right hand (so as to ensure the maximum opening degree between the pressing plate chuck 23 and the tightening wheel 24), the overlapped part of the plastic steel belt 17 is simultaneously inserted between the pressing plate chuck 23 and the tightening wheel 24, the upper plastic steel belt 17 is plugged into the groove of the cutter frame 19, and then the bidirectional air motor assembly 3 is loosened, so that the tightening wheel 24 tightly clamps the double plastic steel belt 17 under the action of the torsion spring 28;

the fourth step: pressing the tightening button 29 with the thumb of the right hand until the plastic steel belt 17 is tightened, and then removing the thumb of the right hand;

the fifth step: pressing the vibration and cutting button 2 by using a thumb of a right hand until the upper layer of the plastic steel belt 17 is cut off and the overlapped double-layer plastic steel belt 17 is subjected to vibration fusion welding, and then removing the thumb of the right hand;

and a sixth step: the handle 5 and the bi-directional air motor assembly 3 are held in the right hand while the valve stem 14 is pressed by the small right hand thumb until the plastic band 17 is released from the tension wheel 24, then the valve stem 14 is released and the pneumatic bander is removed from between the package 18 and the plastic band 17.
