PLC controlled high line sizing machine with multi¡point drive is offered by J V Engineers. Perfect control of size pick-up, stretch and hairiness are the salient features of this high-line sizing machinery.
- Optimum and uniform size pick-up
- Minimum loss in elongation
- Minimum hairiness
- Automatic tension control in different zones through PLC
- Automatic control of different parameters such as temperature in size box I cylinder, squeezing pressure, beam pressure & pneumatic brake at creel
- Higher production with good quality
- User-friendly HMI (Human Machine Interface)
Programming of the machine
The drive, temperature of cylinders and size box, tension in different zones, squeezing roll pressure and warper beam braking pressure, all are controlled through PLC and can be effectively controlled through user friendly HMI provided at the head stock. This can also be provided in local languages for easy of operator. Besides the push button stations, a handy is also provided with the machine which gives flexibility to the operator to operate the machine from any place along the length of machine.
Direct & Indirect Heating
Size box is provided with direct heating arrangement for getting the required temperature of the size mix uniformly across the size box on all sides to ensure uniform size pick¡up. Indirect heating is also provided with help of additional jacketing to ensure heating of size at bottom and avoid dilution of size solution as well as to compensate the heat loss to atmosphere. Size circulation system is provided to maintain level of size solution for uniform size pick-up.
Drive of the drying cylinder
Sized warp sheet driving the cylinders helps in the shrinkage of warp sheet during drying, specially in case of split drying. The cylinders are also provided with temperature control arrangements in required groups.
Multi motor drive
Multi-motor drive is provided, with help of PLC controlled drive, along the length of sizing machine to ensure sized warp sheet with minimum loss in elongation, and thus giving higher residual elongation for higher efficiency & good quality at shuttleless weaving machines, running at high speed.
Wet splitting is done with the help of steam heated rolls, in case of heavy qualities, to reduce hairiness as well as reduce size dropping, which might take place at leasing zone in sizing & on the loom.
Uniform size pick-up
This is achieved across the warp width with the help of special anti deflection squeeze rolls and along the length with proportionate squeezing pressure, controlled through PLC as per the change in machine speed (Craw l to running speed and vice-versa).
The special design of squeezing roll surface ensures minimum hairiness as sizedwarp sheet does not steak to squeezing roll because of its non-stickiness. Bottom, rolls with size-rock coating also helps in reducing hairiness.
