Common problems with the axxon dispensing valve firing pin and nozzle mainly include the following points, and the following detailed solutions can be adopted:

1. Blockage problem

Solution:

Choose the right glue: Make sure to use glue that is compatible with the equipment to avoid curing or precipitation due to inappropriate glue composition.

Regular cleaning: Clean the nozzle and striker regularly during use to avoid glue residue causing blockage.

Use a filter: Install a filter at the glue input end to prevent impurities from entering the dispensing system.

Temperature control: For glue that is easy to cure, control the appropriate temperature and ambient humidity to avoid premature curing of the glue.

2. Wear of the Firing Pin

Solution:

Replace the striker regularly: Check and replace the striker regularly according to the frequency of use and degree of wear.

Choose wear-resistant materials: Use strikers made of more wear-resistant materials, such as carbide or ceramic materials, to extend the life of the striker.

Use a more precise striker controller: Ensure the movement accuracy of the striker and reduce unnecessary impact and wear.

3. Glue leakage

Solution:

Check the seal: Check the seal between the nozzle and the striker regularly to ensure that there is no wear or aging, and replace it in time if necessary.

Adjust the glue amount and pressure: Avoid sealing failure caused by excessive glue amount and pressure, and set the equipment parameters reasonably.

Use anti-leakage design: Choose a nozzle or dispensing valve with anti-leakage design to reduce the risk of leakage.

4. Firing Pin adhesion

Solution:

Choose low-viscosity glue: According to the process requirements, use low-viscosity glue to reduce the adhesion of glue to the pin.

Add anti-stick coating: Add anti-stick coating to the surface of the pin, such as fluoroplastic or other anti-stick materials, to prevent glue adhesion.

Regular cleaning: During use, clean the pin and nozzle regularly to avoid adhesion problems after long-term work.

5. Glue deposition

Solution:

Clean the nozzle regularly: Clean the nozzle immediately after each use to prevent glue residue from solidifying. Use special cleaning agents and tools for cleaning.

Use automatic cleaning function: Some advanced dispensing equipment is equipped with an automatic cleaning function, which can automatically clean the residual glue after work.

Short-term shutdown protection: If the equipment is shut down for a short time, set the nozzle heating or ventilation to prevent glue deposition and solidification.

6. Uneven glue discharge

Solution:

Calibrate equipment: Regularly calibrate the pressure, time and glue discharge volume of the dispensing equipment to ensure the stability of the dispensing process.

Replace worn parts: Replace worn nozzles or needles in time to ensure the accuracy of the equipment's glue discharge.

Check glue quality: Ensure the stability of glue quality to avoid uneven glue discharge due to uneven glue concentration or composition changes.

7. Firing Pin breakage

Solution:

Use durable materials: Choose needles made of stronger and more durable materials, such as tungsten carbide or stainless steel, to improve the resistance of needles to breakage.

Monitor the working environment: Avoid hard objects around the needle to ensure that the collision force between the needle and the target is uniform.

Check equipment adjustment parameters: Reasonably set the working pressure and speed of the needle to avoid excessive pressure or too fast action causing the needle to break.

8. Dispensing valve maintenance

Solution:

Establish a regular maintenance system: Regularly check the needle, nozzle and related accessories, perform maintenance and cleaning, and prevent dispensing valve damage.

Provide operation training: Ensure that operators are familiar with the dispensing valve usage specifications to avoid problems caused by improper operation.
