GU8320 High-Speed Valve Sack Bottomer Overview
Configurations
-
Feeding unit
Adopts a planetary rotary vacuum suction system for stable and efficient tube feeding.
Equipped with double-tube detection and blockage detection to ensure continuous, reliable operation.
-
Arrangement unit
Synchronous belt positioning blocks keep the spacing between paper tubes consistent.
Double-tube rejection function removes overlapping or incorrectly fed tubes.
Exhaust holes are pierced at the valve end of the paper tube to support smooth bottom forming and bag processing.
-
Bottom Opening and Forming Mechanism
Each oblique creasing unit and straight cutting unit is controlled by an independent servo motor, allowing the corresponding positions to be adjusted digitally.
The vacuum opening mechanism opens the end of the paper tube, allowing the forming unit to enter the tube smoothly.
The forming mechanism opens the upper and lower sides of the paper tube end, forming the bag bottom into a symmetrical diamond shape.
The pressing unit works with the forming mechanism to form the bag bottom while pressing the diamond-shaped structure firmly into place.
-
GU8320-05A Valve Patching Unit (Optional)
The paper strip feeding, cutting, valve patching, and glue melting units are controlled by independent servo motors, allowing the paper strip length, folded valve length, and insertion position to be adjusted digitally.
The automatic glue melting function helps prevent the adhesive from solidifying when the machine is stopped.
The edge guiding system detects the edge of the paper strip to keep it in the correct position.
The tension control system maintains stable paper strip tension during operation.
-
Tubular Valve Mechanism (Optional)
The paper strip traction, cutting, valve tube pasting, and glue melting units are controlled by independent servo motors, allowing the strip length, folded valve length, and insertion position to be adjusted digitally.
The automatic glue melting function helps prevent the adhesive from solidifying when the machine is stopped.
The edge guiding system detects the edge of the paper strip to keep it in the correct position.
The tension control system maintains stable paper strip tension during operation.
The mechanism can cut thumb notches for valve openings.
The paper strip can be formed into a tube and then inserted into the paper bag. One hot-melt glue unit is included.
-
Internal Reinforcement Mechanism (Optional)
The paper strip feeding, cutting, reinforcement patching, and glue melting units are controlled by independent servo motors, allowing the strip length, folded length, and insertion position to be adjusted digitally.
Automatic glue melting function helps prevent the adhesive from solidifying when the machine is stopped.
The edge guiding system detects the edge of the paper strip to keep it in the correct position.
The tension control system maintains stable paper strip tension during operation.
-
Bottom Gluing Mechanism
The gluing wheel is controlled by an independent servo motor, allowing the gluing position to be adjusted digitally.
The automatic glue melting function helps prevent the adhesive from solidifying when the machine is stopped.
-
External Reinforcement Mechanism (Optional)
The paper strip feeding, cutting, reinforcement patching, and glue melting units are controlled by independent servo motors, allowing the paper strip length, folded length, and insertion position to be adjusted digitally.
The automatic glue melting function helps prevent the adhesive from solidifying when the machine is stopped.
The edge guiding system detects the edge of the paper strip to keep it in the correct position.
The tension control system maintains stable paper strip tension during operation.
The color mark tracking function detects marks on the paper strip for automatic cutting.
-
Bottom Turning Mechanism
The mechanism can turn the bag bottom upward or downward.
The left and right conveying guide rails allow the machine to produce paper bags with small center distances as well as bags with wider bottoms.
Bags are automatically rejected when the bottom cannot be opened properly.
-
Compacting and Counting Mechanism
The counting function allows the target quantity to be adjusted according to production requirements.
The compacting function allows for pressing the paper bags flat, ensuring more consistent finished output.
When the preset quantity is reached, the valve bag discharging function automatically transfers the finished bags for organized output.
-
Electrical Control System
Equipped with a complete electrical control system for coordinated operation and process control.
