नाइट्राइल दस्ताने उतारने की मशीन: सामान्य समस्याएँ और समाधान

The adoption of automated stripping machines in nitrile glove production has significantly improved efficiency and reduced glove damage rates compared to manual stripping. However, these machines often encounter operational challenges. Below is Fengwang’s summary of common nitrile glove stripping machine issues and their solutions.

1. Gloves Sticking to Molds (Poor Release)

Possible Causes:

(1) Residual coagulated latex or dirt on molds

समाधान: Clean molds regularly with warm water or specialized cleaners to remove residue.

(2) Uneven or insufficient release agent spraying

Solution: Inspect the release agent system; ensure even spraying and adjust concentration or switch brands if needed.

(3) Inadequate vulcanization temperature/time, leading to incomplete curing

Solution: Optimize vulcanization: adjust oven temperature (typically 110–130°C) and duration (based on film thickness).

(4) Mold temperature too high/low

Solution: Regulate mold temperature; ensure cooling to 40–60°C before stripping.

2. Glove Tearing During Stripping

Possible Causes:

(1) Uneven or overly thin latex film

Solution: Adjust dipping process: check latex tank concentration and dipping time for uniform coating.

(2) Excessive stripping force or misaligned mechanics

Solution: Calibrate stripping mechanism: inspect pneumatic/mechanical pressure to avoid aggressive stripping.

(3) Burrs or damage on mold edges

Solution: Polish molds: smooth out rough edges or worn areas.

(4) Latex formula issues (e.g., improper crosslinker ratio)

Solution: Review latex formulation: collaborate with suppliers to optimize vulcanization and film formation.

3. Glove Deformation Post-Stripping

Possible Causes:

(1) Insufficient cooling before stripping

Solution: Extend cooling: add air-cooling or natural cooling stages.

(2) Uneven conveyor belt tension

Solution: Adjust conveyor speed to prevent stretching and ensure smooth transfer.

(3) Incomplete vulcanization (poor elasticity)

Solution: Recheck vulcanization parameters: verify temperature and time compliance.

4. Frequent Machine Jamming

Possible Causes:

(1) Inadequate lubrication of mechanical parts

Solution: Routine maintenance: lubricate chains, rails, etc.

(2) Faulty sensors or signal interference

Solution: Inspect sensors: clean or replace malfunctioning photoelectric/proximity switches.

(3) PLC programming errors

Solution: Reset control system: reboot PLC and eliminate signal disruptions.

5. Release Agent Waste/Contamination

Possible Causes:

(1) Leaks or poor atomization in spraying system

Solution: Maintain nozzles: clear clogs and adjust spray pressure/angle.

(2) Failed recycling system

Solution: Install recovery units: add filtration for release agent reuse.

Preventive Maintenance Tips

Daily: Clean molds, check release agent levels, monitor unusual noises.

Weekly: Lubricate moving parts, calibrate sensors.

Monthly: Replace worn seals, test vulcanization temperature uniformity.
