Product Introduction

Rainproof tarpaulins for high-speed rail construction require seamless splicing of 12m wide and 50m long fabrics. Traditional segmented welding only completes 8 meters a day, and multiple joints lead to water leakage in heavy rain. Marine deck tarpaulins demand wear-resistant, seamless joints, but manually heat-sealed seams crack in 3 months. This 15-25KW HF Tarpaulin Welding Machine enables continuous welding via a 10m ultra-long track, paired with a gantry-type movable welding head. It solves efficiency and waterproofing pain points for engineering tarpaulins and increases marine tarpaulin joint wear resistance by 6 times, fully meeting mass production needs of extra-large tarpaulins.

Product Features

10m ultra-long track system: Supports one-time continuous welding of 1-10m wide tarpaulins without segmentation. 50m long tarpaulin splicing takes only 25 minutes, 7 times more efficient than traditional equipment.

Intelligent tension control feeding table: Automatically adjusts tarpaulin tension during feeding to avoid stretching deformation. Weld straightness error ≤0.3mm, ensuring waterproof sealing of engineering tarpaulins.

High-frequency energy automatic compensation circuit: Real-time power adjustment based on tarpaulin thickness (0.8-2.0mm), no burnout for thin fabrics and full penetration for thick ones. Weld tensile strength ≥250N, meeting marine tarpaulin industry standards.

Gantry-type movable welding head: The head moves freely along the track to adapt to welding needs at different positions. With a visual operation panel, one person can complete ultra-long tarpaulin welding.

Application Scenarios

High-Speed Rail Construction Rainproof Tarpaulin Scenario: High-speed rail box girder construction requires 12m wide and 40m long rainproof tarpaulins. Traditional segmented welding creates 8 joints, which leak in heavy rain. The machine achieves seamless continuous welding via a 10m ultra-long track, splicing 40m tarpaulin in 20 minutes. The weld waterproof rating reaches IPX7, withstanding heavy rain soaking without leakage. It completes 3 tarpaulins a day, meeting construction schedule demands.

Marine Deck Tarpaulin Scenario: Ship decks require 15m long and 8m wide waterproof tarpaulins. Manually heat-sealed seams have a wear resistance of only 2000 cycles, cracking in 3 months. The machine's high-frequency energy compensation circuit increases weld wear resistance to ≥12000 cycles, extending service life to 2 years. The seamless design prevents seawater penetration, reducing ship maintenance costs.

FAQ

1.Q: Can the machine weld 12m wide ultra-wide engineering tarpaulins in one continuous pass?

A: The 10m ultra-long track supports one-time welding of 1-10m wide tarpaulins. 12m wide tarpaulins can be welded in two passes, with joint strength consistent with the tarpaulin body and IPX7 waterproof rating, meeting engineering requirements.

2.Q: Can high-frequency energy fully penetrate 2.0mm thick marine tarpaulins?

A: The 25KW model's energy compensation circuit penetrates 2.0mm thick tarpaulins, with weld tensile strength ≥250N-5 times stronger than manual sewing, meeting marine tarpaulin wear standards.

3.Q: Will the tarpaulin stretch and deform during ultra-long track welding?

A: The intelligent tension control feeding table automatically adjusts tension, with a stretch rate ≤0.2%, ensuring precise tarpaulin dimensions and weld straightness error ≤0.3mm.

4.Q: Will high-frequency output stability decrease after 10 hours of continuous operation?

A: Adopts water-cooled + oil-cooled dual heat dissipation system, keeping the electron tube temperature below 55℃. High-frequency output fluctuation ≤2% after 12 hours of continuous operation, ensuring mass production consistency.

5.Q: Will welded marine tarpaulin joints degum under seawater immersion?

A: High-frequency molecular fusion fully fuses the PVC coating, with joints resisting seawater immersion for ≥180 days without degumming or cracking, meeting ship industry anti-corrosion standards.

6.Q: Can the track length be customized? What is the maximum supported length?

A: Track length supports 5-15m customization, enabling one-time continuous welding of up to 15m wide tarpaulins to adapt to ultra-wide needs in different scenarios.

7.Q: Will welded tarpaulin joints become brittle in -30℃ low-temperature environments?

A: Welding temperature is precisely controlled at 160-180℃, melting only the PVC coating without damaging the substrate. Weld toughness matches the tarpaulin body, maintaining elasticity at -30℃.

8.Q: How many operators are needed? Can ordinary workers operate it?

A: With a visual operation panel and automatic feeding system, one ordinary worker can operate independently after 2 hours of training, eliminating the need for professional technicians and reducing labor costs.
