The precautions for using a screw valve dispensing machine mainly include the following aspects:

Preparation before operation: Before using the screw valve dispensing machine, it is necessary to fully master its operating knowledge and ensure stable power and voltage. After turning on, pay attention to whether there is any abnormal noise from the dispensing machine. If there is any abnormal response, immediately shut down the machine.

Clean environment: Keep the assembly workshop clean and prevent dust from entering the dispensing machine, as small amounts of dust may cause bubble problems. Ensure that the pipeline is installed correctly and sealed properly to prevent the generation of small bubbles.

Proportional testing: Before conducting large-scale production, small-scale trials and proportional testing should be conducted first. To ensure accurate feeding of adhesive A and B, it is usually set based on the data provided by the adhesive supplier. The test results can be considered accurate within a reasonable range of error.

Debugging and maintenance: During the operation process, maintain a stable operating speed and dispensing volume to ensure the uniformity of dispensing and product quality. During debugging, attention should be paid to the selection of needle, dispensing time, and pressure setting to avoid problems caused by excessive or insufficient pressure.

Daily maintenance: Keep the production environment of the dispensing machine clean, clean the site promptly after each dispensing, and keep the components clean. When not in use for a long time, the power should be unplugged to avoid safety accidents and machine damage.
