After the rack 29 drives the piston cylinder 3 to reset, the first incomplete gear 21 is disengaged from the first gear 23, so that the first incomplete gear 21 is engaged with the second gear 25, and the second rotating rod 24 drives the disc 7 to rotate.
When the deformation expansion degree of the air bag 6 is large, the distance between the sliding block 72 and the second rotating rod 24 is large, so that the rotating block 73 and one end, far away from the second rotating rod 24, of the two first connecting rods 74 slide along the sliding frame 75, and when the disc 7 rotates, the position of the sliding block 72 from the circle center of the disc 7 becomes large due to the fact that the sliding frame 75 is limited by the second connecting rods 13, the rotating diameter of the laser cutter 4 becomes large, and cutting of plastic bags with large diameters is completed.

First, the first incomplete gear 21 is meshed with the first gear 23, so that the first gear 23 rotates, and the first rotating rod 22 thereon drives the second incomplete gear 26 to rotate, and since the second incomplete gear 26 is intermittently meshed with the third incomplete gear 28, and the rack 29 is intermittently meshed with the second incomplete gear 26 and the third incomplete gear 28 respectively, when the second incomplete gear 26 and the third incomplete gear 28 are meshed, the third incomplete gear 28 is rotated clockwise, so that the third incomplete gear 28 drives the rack 29 to slide towards the third incomplete gear 28, and when the second incomplete gear 26 and the third incomplete gear 28 are not meshed, the second incomplete gear 26 drives the rack 29 to slide towards the second incomplete gear 26, so that the third incomplete gear 28 rotates anticlockwise, and further the rack 29 slides reciprocally.
When the rack 29 slides towards the third incomplete gear 28, the fixing rod 38 drives the piston cylinder 3 to synchronously slide towards the third incomplete gear 28 until the contact block 34 contacts with the plastic bag, so that the contact block 34 drives the piston rod 31 and the sealing plug 32 to slide towards the air inlet pipe 35, and when the rack 29 slides towards the third incomplete gear 28, the fixing rod 38 drives the piston cylinder 3 to synchronously slide towards the second incomplete gear 26, so that the elastic force of the first spring 33 is released, the piston rod 31 and the sealing plug 32 slide towards a direction far away from the air inlet pipe 35, and then the air pressure in the piston cylinder 3 is reciprocally changed, which is described in detail as follows:

When the deformation expansion degree of the air bag 6 is large, the distance between the sliding block 72 and the second rotating rod 24 is large, so that the rotating block 73 and one end, far away from the second rotating rod 24, of the two first connecting rods 74 slide along the sliding frame 75, and when the disc 7 rotates, the position of the sliding block 72 from the circle center of the disc 7 becomes large due to the fact that the sliding frame 75 is limited by the second connecting rods 13, the rotating diameter of the laser cutter 4 becomes large, and cutting of plastic bags with large diameters is completed.
When the degree of deformation expansion of the airbag 6 is small, the same principle as above is adopted, so that the rotation diameter of the laser cutter 4 becomes small, and cutting of the plastic bag with the small diameter is completed.
Because fixedly connected with rotates the inductor on disc 7, and rotate inductor and laser cutter 4 electric connection for when disc 7 rotates, laser cutter 4 begins to work, and when disc 7 stops rotating, laser cutter 4 stops working, has avoided the waste of the energy.
The laser cutter 4 is an existing device and will not be described in detail here.
And then reached and confirm the rotation diameter size of laser cutter 4 through the diameter size of plastics case and bag for need not manual measurement and regulation, degree of automation is high, saves time's effect.
After the laser cutter 4 is cut, the first incomplete gear 21 is disengaged from the second gear 25, at this time, the conveying and fixing mechanism is operated, the next plastic bag with cut is conveyed to the right opposite side of the contact block 34, and then the first incomplete gear 21 is engaged with the first gear 23, so that the feedback positioning mechanism starts to operate.
At this time, when the rack 29 slides in the direction of the third incomplete gear 28, the support rod 61 drives the telescopic rod 62 to slide synchronously, so that the telescopic rod 62 is matched with the round table 65, and the air in the air bag 6 is discharged through the round table hole and the exhaust pipe 63 and blown onto the cut plastic bag, so that the scraps on the plastic bag are blown away.
Then after the gas is exhausted, when the second spring 66 is accumulated to the maximum elastic force, the telescopic rod 62 continues to slide, so that the round table 65 generates thrust to the telescopic rod 62, thereby overcoming the elastic force of the third spring 15, so that the telescopic rod 62 is retracted, and the elastic force of the second spring 66 is released, so that the round table 65 reseals the round table hole, and then the gas is continuously input from the piston cylinder 3, and the above steps are repeated.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
