Product Introduction

When splicing sunshade tarpaulins for night market stalls, small workshops use manual heat sealing with low efficiency-only 3-4 pieces a day, and seams often come loose or leak in rain. When repairing tarpaulins for logistics trolleys, traditional equipment cannot adapt to irregular damage welding. This PVC tarpaulin welding equipment (single-head G-type tarpaulin high-frequency machine) features a G-type gantry open structure for free entry and exit of wide tarpaulins, paired with a dual-roller continuous welding head. It solves the efficiency pain points of small workshops and accurately repairs warehouse tarpaulin damage, fully meeting the needs of small-batch, multi-specification tarpaulin processing.

Product Features

G-type gantry open structure: Tarpaulins can enter and exit freely from both sides, adapting to 1-2m wide tarpaulin splicing without manual repositioning, saving operating space.

Dual-roller continuous welding head: Tarpaulins pass through rollers at a constant speed during welding, resulting in flat, wrinkle-free seams. 1m tarpaulin splicing takes only 1.5 minutes, 4 times more efficient than manual heat sealing.

NL-5557 spark protection system: Cuts off high-frequency output within 0.05 seconds when dust or impurities are detected on the tarpaulin surface, preventing tarpaulin burning with a material loss rate ≤0.2%.

Precise temperature-controlled welding circuit: Supports welding of 0.3-1.2mm thick PVC tarpaulins, no burnout for thin tarpaulins and firm welding for thick ones, with weld tensile strength ≥160N.

Application Scenarios

Small Tarpaulin Workshop Scenario: Night market sunshades require splicing 1.5m wide and 3m long PVC tarpaulins. Manual heat sealing can only process 3 pieces a day. With the dual-roller continuous welding head, the equipment splices 1m in 1.5 minutes, processing 15 pieces a day-5 times the productivity. The weld waterproof rating reaches IPX5, ensuring no leakage during rainy market days.

Logistics Warehouse Tarpaulin Repair Scenario: Express trolley tarpaulins have 10-30cm irregular damages that traditional equipment cannot weld accurately. The G-type gantry structure flexibly adjusts tarpaulin position, and the precise temperature-controlled circuit ensures firm welding at damaged areas. The repaired tarpaulin has a wear resistance ≥3000 times, extending service life to 8 months and reducing warehouse consumable costs.

FAQ

1.Q: Can the equipment splice 1.8m wide night market tarpaulins in one go?

A: The G-type gantry structure supports free entry and exit of 1-2m wide tarpaulins, allowing 1.8m wide tarpaulins to be spliced in one go without segmentation, ensuring joint integrity.

2.Q: Will 0.3mm thin PVC tarpaulins be burned through during welding?

A: The precise temperature-controlled circuit automatically adjusts power. For 0.3mm thin tarpaulins, the temperature stabilizes at 140-150℃, melting only the surface PVC without damaging the substrate, with a yield rate of 99.5%.

3.Q: Can the equipment accurately position welding for irregular damages on trolley tarpaulins?

A: The G-type gantry structure adjusts tarpaulin position 360°, and the manually adjustable head aligns precisely with irregular damages. The welded area has a tensile strength ≥150N, meeting trolley vibration requirements.

4.Q: Will high-frequency output become unstable after 4 hours of continuous operation?

A: Adopts air-cooled + water-cooled dual heat dissipation system, keeping the electron tube temperature below 60℃. High-frequency output fluctuation is ≤2% after 8 hours of continuous operation, ensuring consistency in small-batch processing.

5.Q: Will welded tarpaulin seams crack when folded for storage?

A: Seams are fused at the molecular level, with toughness consistent with the tarpaulin itself. They withstand ≥500 folds without cracking, adapting to frequent storage of night market tarpaulins.

6.Q: Does the equipment require professional technicians to operate?

A: Equipped with a visual temperature control panel and one-click start, ordinary workers can master operation in 1 hour without professional qualifications, suitable for small workshop manpower configuration.

7.Q: Will the odor generated during welding affect the night market environment?

A: Uses low-smoke, eco-friendly high-frequency welding technology with no pungent odor when PVC melts, complying with night market environmental requirements and not affecting customer flow.

8.Q: Can the equipment weld PVC-coated oxford cloth tarpaulins?

A: Supports welding of PVC-coated oxford cloth. The precise temperature-controlled circuit adapts to coating thickness, ensuring no coating peeling after welding. The weld waterproof rating reaches IPX5, meeting outdoor tarpaulin durability needs.
