AI Technical Summary
Existing belt roller lubrication technology suffers from problems such as untimely lubrication, low efficiency, high labor intensity, safety hazards, and uneven oil volume. In particular, the poor fluidity of grease in low-temperature environments leads to increased equipment wear, and automatic control devices are prone to uneven flow, sensing deviations, and inconvenient maintenance.
A belt roller lubrication device is adopted, which uses a spring-driven piston to automatically inject grease into the bearing part. The grease outlet quickly connects with the standard oil hole of the existing equipment to achieve automated lubrication, avoid manual intervention, and simplify the maintenance process.
Ensuring continuous and stable grease injection in low-temperature environments reduces worker workload, improves lubrication efficiency and equipment reliability, reduces equipment downtime, lowers maintenance costs, and avoids uneven lubrication and safety hazards.
