Electronic Screw Packer
Model: VTC-VSP-1 (For Valve Type Bag)
Model VTC-VSP-1 is specially designed, unique, Screw-feeder type bag filling to pack any powered material in prestitched valve type laminated HDPE / paper bags. Model is equipped with Pneumatic Ejecting system for smooth ejection of bag.
Modified low end uses model with Impeller feeder type machine is also available for powder filling in non-laminated bags. Both machines can have Pneumatic Bag holding system (attachment) for filling in open mouth bags.
OPERATION OF THE MACHINE:-
- The Machine to be fitted below the Storage Hopper. Material flows into the damper controlled by Pneumatic Cylinder.
- The machine will hold bag below which the box or drum has to be put. After completion of filling, the bag will automatically drop in to below box or drum.
- This machine is a two stage feeding type.
- On initiating the system both the flap opens & material falls into the weighing hopper. As soon as the 90 % of the weight is reached one flap closes & fine feed starts till the target weight is reached the 2nd flap closes, stopping further fall of material into weighing hopper.
- The Butterfly Valve provided below the weighing hopper opens & the material falls into the bag through the open mouth bag holder.
- A Slat Conveyor will be placed below the packing machine which will carry the filled bags.
Model: VTC-PMT-2 (For Open Mouth Bag)
Model VTC-PMT-2 is a high accuracy bagging machine for filling powder products like chemicals, lime, pigments, flour in open-mouth bags.
The specially designed screw feeder carries material uniformly & has a very large inlet to prevent arching / bridging normally occurring in the inlet neck portion. It has agitating & conditioning screws on the same shaft to ensure smooth and uniform flow of material. The 3-speed controller rotates the screw in 3-speeds, viz, coarse, fine & superfine to ensure very high accuracy in filling.
Machine is equipped with re dispensing feature. Special lining of hopper to suit material characteristics (Corrosive / abrasive etc) can be provided.
THE OPERATION CYCLES OF AUTO FILLING MACHINE VTC-PMT-2:-
- Once the bag is clamped in the Bag holder, machine initiates automatically. The bag holder gets activated by Pneumatic Cylinder.
- The microprocessor auto-tares the weight & screw feeder rotates at full speed pushing the material into the bag.
- As soon as the first set point (i.e., approximately 75 to 80 % of target weight) is reached the Microprocessor reduces the speed of the motor through AC Drive & screw feeder pushes the material slowly into the bag. As soon as the second set point reaches (i.e., approximately 95% of target weight) the Microprocessor further reduces the speed of the motor through AC Drive & Screw Feeder pushes the material very slowly into the bag.
- As soon as the target weight is reached. The screw feeder stops instantly.
- The filled bag would be released on the slat conveyor.
- A Stitching Machine/Heat sealing machine will be provided above the conveyor will stitch/Seal the bag.
- It is also known as Chemical powder packing machine, lime packing machine, pigment packing machine, flour packing machine in open-mouth bags.
