Automatic Center Sealing Bag Making Machine

Quantity:
  • LQSD-450A
  • UPG

Equipment and relevant Parameter

1. Unwinding turret:

a) Tension force control of unwinding.

⑴ permanent tension brake, magnetic powder detent

⑵ Unwinding positive feeding structure, transducer sends out material on average speed

⑶ Control mode: computer instruction, dancing roller displacing sensor controls roll sending out speed

⑷ Fixed taper cone nip unwinding shaft (air expanding shaft)

b)   Edge position control (EPC)

     ⑴ Configuration: screw mandrel secondary control, unwinding turret movement

     ⑵ Control modality: reflection electric potentiometer sensor testing, independent control.

     ⑶Tracking accuracy: 0.5mm

     ⑷Adjustment range: 150mm

     2. folding section

     ⑴ Configuration: two sides folded at same time, one side adjustable

     ⑵ Adjustment: manual regulation

     3. Vertical sealing setup:

     ⑴ Configuration: vertical disposition iron pressing, cooling assembly spring pressing structure

   ⑵ Drive: main electric machinery drives coupling rod of eccentric mechanism to do curve motion

   ⑶ Quantity: One team on vertical thermal sealing, one team on cooling, two teams on vertical shaping.

   ⑷ Length: 840mm(sealing unit)  720mm(shaping unit)

     4. Horizontal sealing setup:  

     ⑴ Configuration: horizontal disposition iron press assembly spring structure, cooling assembly

   ⑵ Drive: main electric machinery drives coupling rod of eccentric mechanism to do vertical motion

   ⑶ Quantity: three teams on thermal sealing, one team on cooling

   ⑷ Length: 510mm

    5. Film feeding device

     ⑴ Configuration: pneumatic pressing rubber roller friction type

     ⑵ Drive: imported fully digital runoff production servo mechanism (Servo motor 1.5Kw, Panasonic Japan)

     ⑶ Transmission: synchronous band and wheel

     ⑷ Control modality: centralized computer control, synchronous length fixing and automatic photoelectrical tracking system)

    6. Middle tension

     ⑴ Configuration: dance roller tension force structure, set signal  

     ⑵ Control modality: centralized computer control

     ⑶ Mechanism of control: complementary trend of dance roller tension movement control the middle servo step length to achieve stop and begin at the same time

     ⑷ Testing form: electromagnetism approaching switch (NPN)

     ⑸ Adjustment range of tension force: 0.1-0.2mm (computer setting, automatic reciprocate)

7. Main transmission device

     ⑴ Configuration:  crank rocker push pulling coupling rod structure

     ⑵ Drive: Panasonic 3KW servo motor controls

     ⑶ Transmission: servo reducer ratio 1:10

     ⑷ Control modality: centralized computer control

     ⑸ Movement mode: main motor running drives frame to do vertical movement

8. Automatic positioning device

     ⑴ Testing form: tracking testing of reflection photoelectrical sensor

     ⑵ Testing accuracy: 0.01- 0.25mm

     ⑶ Integrative positioning accuracy: ≤0.5-1mm

     ⑷ Photoelectrical searching range: ±3mm

     ⑸ rectifying equalizing range: ±3mm

     ⑹ positioning rectifying method: servo tracks current compensating, photoelectrical automatic movement rectify system

9. Temperature control setting:

     ⑴ Testing form: thermocouple test
