Double servo technology and servo servo membrane cross sealing technology, which is currently the most advanced technology of intermittent bag packaging machine used for packing machine, in order to achieve high speed and stable operation, as follows:

  3.1, servo membrane technology

In a batch bag packaging machine, packaging film before feeding by ordinary motor drive crank intermittent strap way, Not only the structure is complex, it is difficult to adjust. General motors and large inertia, thus drawing film poor positioning accuracy, easy to appear the bag length. At the same time the general motor drawing film speed is slow, cannot achieve fast film feeding, so can further improve the packing speed. If the drive wheels with servo motor drawing film, can be set in advance, from the operation of AC servo motor each run time and pause in the controller in time, with excellent acceleration of AC servo motor and positioning performance, achieve accurate control of the length of the film feeding. Especially in the control system with color correction device, color deviation signal through the detection switch detected by the controller, transported to the AC servo motor, acceleration performance and control precision of excellent AC servo motor, which can quickly and accurately correct the deviation.

  3.2, servo horizontal sealing technology

At present, the vertical packaging machine adopts horizontal cylinder type sealing technology driven, its working principle is the reciprocating piston Linear motion into reciprocating motion relative clearance transverse sealing copper block. The utility model has the advantages of simple structure, low cost, but also more obvious shortcomings of the transverse sealing form: first, the pneumatic system is powered by 0.5 to 0.7Mpa of the compressed air, so as to dynamic components of high power, when the packing speed at 70 bales above, there will be a cross seal pressure is not enough, thus prone to leakage of the transverse sealing. At the same time, the end of the pneumatic action, at the end of the relatively large impact, thus becoming a major source of noise of packing machine. Secondly, every change of packing speed, to re adjust the throttle valve to increase the labor intensity of workers. Again, the pneumatic system using the media need to consider the system sealing performance, so after a long time, is also the problem of leakage of cylinder and electromagnetic valve and pipe air, increase the workload of maintenance workers. Finally, the pneumatic system is the use of compressed air, conversion loss of energy, so it worked smoothly and the response is relatively poor, work faster the more obvious manifestations.

The transverse sealing technology of servo, servo motor and servo motor special high speed reducer to replace the ordinary cylinder drive, non constant speed to fully meet the rapid closure, transverse sealing by the servo motor end of the buffer, quickly open the requirements. At the same time, servo motor direct drive cross sealing block, the transmission efficiency is almost no loss. The signal connection between digital control and servo driver can achieve synchronization with the film is convenient, and completely avoid the tear film film is not in place or pull over film film packing case. The sealing device using servo motor control, with a strong flexibility and adaptability, servo motor control can simulate motion curve to obtain good dynamic characteristics, compared with the cylinder driving cylinder to drive the moving distance of the sealing device, the synchronous motion feature is always the same, the movement of human can't according to the load. In response, to adjust. The servo motor is variable and active adaptability, and conveying transverse sealing force is much greater than the cylinder driving force, so as to achieve the purpose of making high speed, stable.
