Feeding unit
The feeding mechanism of valve sack bottomer employs rotary rollers to feed. Small rollers rotate around big rollers. Meawhile, small ones rotate reversely to take the feeding. A big roller rotates for one time is capable of feeding 8 paper bag tubes.
Rotating vaccum feeding is the easiest, most convenient way, also considered as reliable and stable. Equipped with arranging and positioning device, this unit ensures the positioning precision of paper bag tubes. -
Flush cut unit
The flush cut unit is capable of making indentations without stopping the machine or adjusting the speed.
This mechanism of valve sack bottomer is equipped with flush cut, mainly used for the bottoming of straight-cut end paper bag tubes. The unit cuts two times on both ends of paper sacks. -
Vacuum opening & bottom forming
The vacuum opening of valve sack bottomer opens the paper bag tube, enabling the handling unit to get inside the tube. The handling unit can open the paper bag from top to bottom.
This mechanism flattens the bags, assisting the handling unit to shape the bag bottom. Meanwhile, the block bottom of paper bag is compacted by the flattening device. -
Valve making
The valve making mechanism pastes valve paper on the bags, forming a valve.
Customers can adjust the parameters on the screen and set valve paper length. -
Interior reinforcement mechanism
The interior reinforcement mechanism pastes reinforcing strip inside the valve to increase its strength.
-
Bottom forming unit
The bottom forming unit is equipped with bottom indentation device to assisting bottom forming, supported with glue wheel device whose shape is adjustable according to the needs and specifications of paper bags. Remember to stick the glue plate to its set place afterwards.
The forming unit is comprised of supporting panels, among which the inward panels support the bottom paper. Outwards panels function as a guide for the bottom paper to form into rectangular-shaped bottoms. Then the compactor will make the bottoms more durable.
The panel size can be adjusted according to the production needs of different bottom size. -
Exterior reinforcement mechanism
The exterior reinforcement mechanism pastes the reinforcing strip outside the valve to enhance the valve strength.
-
Flipping unit
After bottoming, paper sacks are changed from verticality to horizontality by the flipping unit.
-
Compacting & valve bag discharging unit
Through the flipping mechanism, paper sacks are sent in at a lower speed while passing the compacting belt. The compacting effect will be more obvious after the bags are arranged together. The mechanism is equipped with counting device; customers can preset paper bag number in the system.
The compacting and counting unit of valve sack bottomer is equipped with vacuum absorbing and accelerating separating device, which is used to separate piled-up paper bags when the bags have reached certain amount set by the system. -
S-shape compacting unit
The S-shape compacting unit is used to compact bottomed paper sacks, bringing sacks into S-shape. With enough compacting time and high adhesive paper bag bottoms, sacks produced by our valve sack bottomer are tidy, of good quality in compacting and indentation, suitable for large scale paper bag production.
This device can be used only with valve sack bottomers (both end pasted) as a set.
Youniker offers both complete line and individual equipment including valve sack tubers and bottomers to satisfy your paper bag production needs.
