Product Introduction

When producing large outdoor tents, manually splicing 3-meter-wide thick canvas can only complete 15 meters a day, and positioning deviations often lead to water leakage at the welds. When processing truck awning fabrics, traditional equipment cannot continuously join long-length materials, and the joints lack wear resistance and are prone to cracking. This Automatic walking style tarpaulin welding machine is specially designed for the long-length splicing of PVC-coated canvas. Relying on the European-style square resonant tank to provide a stable high-frequency electric field, it enables rapid fusion of canvas molecules. Combined with the automatic walking welding head and laser positioning, it not only solves the efficiency and precision pain points of manual splicing but also makes the weld strength comparable to the canvas itself, fully meeting the mass production needs of tents and awning fabrics.

Product Features

Laser auxiliary positioning system: During the splicing of long canvas, dual laser lamps accurately project the seam trajectory, and the welding head walks automatically along the trajectory. The weld straightness error is ≤0.5mm, completely eliminating the risk of water leakage.

Customizable extra-long welding die: Supports one-time forming splicing of 1-3.5m wide canvas without segmental operation. Splicing 10m long canvas only takes 3 minutes, increasing efficiency by 6 times.

Double roller feeding workbench: The canvas is freely transported through the workbench rollers, avoiding material stretching and deformation caused by manual dragging, and ensuring the accuracy of finished product dimensions.

Intelligent high-frequency compensation technology: Automatically adjusts the output power according to the canvas thickness (300-700g/m²), ensuring no burnout for thin canvas and full welding for thick canvas, with a weld tensile strength ≥220N.

Application Scenarios

Large Outdoor Tent Canvas Splicing Scenario: Scenic camping tents need to splice 3.2m wide and 12m long PVC-coated canvas. Manual splicing not only takes 8 hours but also often leads to water leakage in rainy days due to seam deviation. With laser positioning and automatic walking welding head, the equipment splices 12m canvas in only 4 minutes. The weld waterproof grade reaches IPX7, which can withstand heavy rain soaking without leakage. It can complete the core splicing process of 15 tents a day, increasing production capacity by 8 times.

Industrial Truck Awning Fabric Joining Scenario: Freight trailer awning fabrics need to continuously join long canvas over 20 meters. The joints of traditional segmental welding are prone to wear and cracking, with a service life of only 3 months. The equipment's customizable extra-long welding die realizes one-time continuous joining. Combined with intelligent high-frequency compensation technology, the weld wear resistance reaches ≥10000 times, and the service life is extended to 2 years, greatly reducing the replacement cost of truck awning fabrics.

FAQ

1.Q: When splicing 3.5m wide extra-wide canvas, can the equipment complete it in one go without segmentation?

A: It supports customization of extra-long welding dies within 3.5m, enabling one-time forming splicing of extra-wide canvas without segmental operation. It not only ensures the integrity of the joint but also avoids the risk of water leakage at the interface.

2.Q: For 700g/m² extra-thick canvas, can high-frequency energy penetrate to the inner layer to achieve firm welding?

A: The European-style square resonant tank has strong output and low high-frequency energy attenuation. Combined with intelligent power compensation, it can completely penetrate 700g/m² extra-thick canvas. The weld tensile strength is ≥220N, which is 5 times stronger than manual sewing.

3.Q: If the canvas surface is uneven during automatic walking, will it affect the weld precision?

A: The double roller feeding workbench can automatically smooth canvas wrinkles, and the laser positioning system corrects deviations in real-time. Even if the canvas surface is slightly uneven, the weld straightness error is still ≤0.5mm.

4.Q: After the equipment works continuously for 8 hours, will the stability of high-frequency output decrease?

A: It adopts a fresh air cooling system and full-mode circulating cooling design, with excellent heat dissipation effect of the electron tube. It can work continuously for 24 hours, and the fluctuation of high-frequency output power is ≤3%, ensuring the consistency of mass production.

5.Q: Will the welded canvas joints become brittle and crack in low-temperature environments?

A: The welding temperature is precisely controlled at 150-170℃, which only melts the PVC coating without damaging the canvas fibers. The weld toughness is consistent with the canvas itself, and it can maintain good elasticity in a low-temperature environment of -20℃ without brittle cracking.

6.Q: Is it troublesome to adjust the equipment when replacing canvas of different widths?

A: The workbench width supports quick adjustment of 1-3.5m without disassembling parts. Combined with the movable welding head design, the adjustment time is ≤5 minutes when replacing canvas of different widths, adapting to the production of multi-specification products.

7.Q: Is the high-frequency radiation generated by the equipment safe for operators?

A: It adopts European-style single-side rear high-frequency grounding and special shielding treatment. The human radiation dose meets the EU CE standard, and the radiation value 3 meters away is close to the background level, ensuring the safety of operators during long-term operation.

8.Q: Can the equipment achieve arc welding if the canvas joint requires it?

A: It supports customization of arc welding dies. Combined with the flexible steering function of the welding head, it can complete arc joint welding with a radius ≥50cm. The weld is smooth without wrinkles, adapting to special needs such as tent corners and awning fabric arc interfaces.
