2800 Semi-automatic Carton Gluer

Scope of Application and Characteristics

This machine is suitable for all kinds of cardboard and corrugated paperboard bonding. It features simple operation and requires no particular technical experience. With a quick changeover in just one minute, it can handle carton widths and heights with a minimum gluing area of about 300 mm. This makes it an ideal box gluing and folding machine for carton production lines aiming for efficiency and reliability.

Main Technical Parameters

Main Structure and Working Principle

The machine consists of one main frame and two conveying frame sections.
Main components include: main engine frame, lifting workbench, front conveying device, front wall block pasting device, middle wall pasting device, mid-section pressing device, and electrical control system.

Working Principle:
After mixing glue evenly, pour it into the glue water bucket and press the corresponding switch button. When the machine rotates properly, glue flows to the paste head and is distributed evenly.
The carton passes through the bottom of the paste head, allowing even glue application. The cardboard then moves through the pressing section where both glued surfaces adhere firmly together, completing the bonding process.

Installation and Testing

1. Fix the machine, adjust the leg screws, correct balance, and secure all bolts.
2. Connect to a three-phase 380 V / 50 Hz power supply (green wire for grounding).
3. After connecting all power lines, check the conveyor belt rotation direction—if reversed, interchange two phase lines to correct it.
4. After wiring, run an empty test by pressing the conveyor control buttons for each section (front, middle, and finished output) to verify proper movement and synchronization.

Operation and Adjustment

Boot Procedure:

1. Turn on the power; press the conveyor start switches.
2. Adjust the height of the front pressing rubber roller so cardboard passes smoothly.
3. Adjust the space between the main engine swing baffle and the middle baffle to ensure carton height consistency (avoid overtightening to prevent glue quality issues).
4. Adjust middle roller height to be about 1.5 times carton thickness.
5. Set glue delivery quantity using the indicator positions “8”, “15”, or “10”.
6. Press blower button to start the fan.

Emergency Stop:
If abnormal operation occurs, press the emergency stop button to immediately halt all motors. Rotate the button in the indicated direction to reset machine operation.

Electrical and Timer Controls

1. Power indicator light: shows when power is on (indicator on) or off (indicator off).
2. Time relay “Rise”: controls the lift time of the feeding station. Turning clockwise increases waiting rise time; counterclockwise decreases it.
3. Time relay “Middle Section”: controls waiting time of the middle conveyor. Clockwise rotation extends its waiting operation time, counterclockwise shortens it.

Machine Maintenance and Lubrication

1. After every production cycle, clean the paste tank to prevent glue blockage.
2. For continuous operation, stop every 4 hours to clean the paste head.
3. After cleaning, apply light oil to connecting parts such as copper rods, gears, and paste head contact areas.
4. Add mechanical gear oil to the motor every six months.
5. Lubricate the chain once a month.
6. Keep the optical sensors clean to avoid detection errors.
7. When the printing zone has large black areas, adjust the electric eye screw clockwise to enhance light sensitivity.
