Common faults and solutions of Dalian glue coating machine

Common faults and solutions of Dalian glue coating machine

During the use of the Dalian glue coating machine, some common faults may occur. The following are these faults and corresponding solutions:

1、 Unstable glue quantity

Fault manifestation: The amount of glue applied varies greatly and unevenly.

resolvent:

Check if the glue pump is working properly, and repair or replace it promptly if there are any abnormalities.

Check whether the hose is blocked or leaking, clean the blockage or replace the hose.

Adjust the pressure parameters of the glue coating machine to ensure stable pressure.

Check if the viscosity of the glue is appropriate. If the viscosity changes significantly, consider adjusting the glue formula or adding a diluent.

2、 Uneven glue application

Fault manifestation: uneven thickness and stripes on the adhesive surface.

resolvent:

Check if the nozzle of the glue gun is blocked or damaged, clean or replace the nozzle.

Adjust the speed and glue quantity parameters of the glue machine to match the current glue task.

Check if the surface of the workpiece is flat, and if there are any unevenness, treat them first before applying glue.

Ensure stable quality of adhesive and avoid uneven coating caused by adhesive issues.

3、 Adhesive does not cure or cures slowly

Fault manifestation: After applying glue, the glue does not cure for a long time, or the curing speed slows down significantly.

resolvent:

Check if the curing conditions of the glue are met, such as temperature, humidity, etc. Ensure that the working environment meets the curing requirements of the adhesive.

Check if the glue has expired or if there are quality issues, and replace it with a new one.

Adjust the heating system of the glue applicator (if any) to ensure that the glue can cure at the appropriate temperature.

Check if the proportion of curing agent added is correct. If adhesive with curing agent needs to be added, ensure that the proportion of curing agent is accurate.

4、 Equipment blockage

Fault manifestation: The rubber hose, glue gun or other parts are blocked, and the glue cannot flow normally.

resolvent:

Immediately stop the gluing operation to avoid further damage to the equipment.

To clean the blocked area, specialized cleaning agents or tools can be used for cleaning.

Check the quality of the glue for impurities or particles that may cause blockage.

Strengthen the daily maintenance of equipment, regularly clean and inspect to prevent blockages from happening again.

5、 Electrical malfunction

Fault manifestations: No display on the control panel, inability to start the equipment, abnormal motor, etc.

resolvent:

Check if the power connection is normal and ensure that the device has a stable power supply.

Check if electrical components are damaged, such as fuses, relays, etc., and replace them promptly if they are damaged.

Contact professional maintenance personnel for repairs to avoid disassembling equipment on your own and causing greater damage.

6、 Mechanical malfunction

Fault manifestation: Abnormal noise, vibration, or component damage during equipment operation.

resolvent:

Shutdown and inspect various components of the equipment to identify the source of the malfunction.

Check whether the transmission components are loose or worn, such as belts, gears, etc., and tighten or replace them in a timely manner.

Check if the bearings are damaged and replace them with new ones if necessary.

Regular maintenance and upkeep of equipment to ensure the normal operation of mechanical components.
