Why say the former is a very important part for VFFS machine?
The bag forming shoulder is a key component of the vertical packaging machine, which has a direct impact on the style, size, and appearance of packaging bags. The quality of the design and manufacture of the bag forming set is restricted by the establishment of the mathematical model of the neckline and the precision of the manufacturing process.
Which parameters need to be confirmed when making a bag forming shoulder for the VFFS machine?
1) bag layout drawing or bag size, film width, vertical sealing width.
2) film material and thickness.
3) Bag forming set mounting dimensions
What are the factors leading to the deviation of the bag forming set?
1) The tension of the film is not balanced.
2) packaging machine frame assembly error.
3) The drawn film synchronous belt is not parallel to the forming tube.
4) The speed of the double servo drawing film synchronous belt is not synchronized.
5) The gap between the forming collar and the forming tube is not uniform.
6) Incorrect placement of the film roller lever
7) The design issues of the bag forming set.
8) processing problems of bag former
