Application Fields
This Computerized High Speed Lockstitch Sewing Machine serves footwear production workshops, leather goods factories, bag manufacturing plants and apparel processing lines. It performs lockstitch sewing on shoe upper linings, leather cut pieces, synthetic leather fabrics and webbing accessories for shoe upper assembly and lining splicing.
Ideal for stitching sports shoe uppers, leather shoe vamps, children shoe linings and shoe tongue components. Adjustable stitch parameters adapt to materials of different thicknesses, delivering neat and firm seams to meet the quality and efficiency requirements of mass shoemaking production.
Operation Guidance
- Check power supply, needle condition and bobbin thread before startup
- Adjust stitch length, thread tension and presser foot pressure according to material thickness
- Test sew on small material sample to confirm stitch quality before formal production
- Place shoe upper cut pieces flat under presser foot, control pedal to start sewing
- Clean thread scraps and dust on machine surface, cut off power after daily work
Installation Guidance
- Place the machine stand on flat solid ground, fix table board stably
- Connect AC220V power supply with reliable grounding wire
- Install needle, bobbin case and auxiliary accessories following operation manual
- Run 3–5 minutes no-load test, finish stitch tension debugging with sample shoe materials
Maintenance & Repair Instructions
Daily Maintenance
Clean surface thread scraps and dust; lubricate needle bar and rotary hook, check thread passing path
Weekly Maintenance
Inspect feed dog and needle plate wear, tighten loose screws and test thread break detection function
Monthly Maintenance
Deep clean internal thread accumulation, check motor belt tension and replace severely worn parts timely
Repair Rules
Solve faults according to panel error prompts; cut off power before disassembly; replace worn rotary hook and needle regularly to guarantee stitch quality
