INTRODUCTION:

WFD-400 three-side sealing zipper zipper bag making machine

Function indication

Application scope

 Material: various compound films

Adaptability

 Bagging speed : 150 parts/min (mechanical design speed ),approx .35m/min

 Bagging width:  Max width 400mm.

 Bagging length：50-2400mm,when the set program is above 400mm,it will automatically changer into multiple conversances.

Notes：The actual operation speed will reduce for the reason of difference of the bag type and

material .

Warping mode

 Fabrication: put the warp beam horizontally and pneumatically lock.

Control: tension is automatically change into multiple conveyances.

Driving mode

 Feeding traction：driven by AC servomotor.

 Upper lower sealing press: driven by AC servomotor.

Functions

 Heat seal :speed of heat seal, duration of heat seal, proportion of heat seal acceleration etc.(main servomotor.

Temperature:0-300℃,contact-free automatic control, CRT displaying.

Automatic count：presetting is available.

Conveyance of finished bag: conveyance quantity is available.

Punching device: time can be preset, continuous or interval punching is available.

Working mode：printing, non-printing.

Mode of multiple conveyances：twice to six times conveyance.

Measurement for length：distance between color scales can be measured photoelectrically.

Message alert: lost of photoelectricity, lost of temperature, warping atarm, servomotor alarm and auto switch off the machine.
