Fully automatic rail-mounted PVC film material heat sealing machine

1. Equipment definition and functional positioning
The fully automatic track-type PVC film heat sealing machine is a high-frequency welding equipment designed for polyvinyl chloride (PVC) film materials. Through high-frequency electromagnetic field or hot air heating technology, the PVC film material is molten and then pressure is applied to complete the bonding. Its core functions include:

Automatic welding: The track-type walking mechanism realizes continuous welding, reduces manual intervention, and improves efficiency.
Precise control: The temperature, pressure, and speed are adjustable to adapt to PVC film materials of different thicknesses (0.1-5mm) and characteristics.
Multi-scene adaptation: supports complex curved surface welding requirements such as inflatable amusement equipment, large tents, membrane structure buildings, and windproof roller blinds.
2. Technical principles and process advantages
High-frequency dielectric heating technology
Use high-frequency electromagnetic fields (27.12MHz or 40.68MHz) to generate polarized friction heat in PVC molecules to achieve rapid and uniform heating.
Advantages: The heating speed is 3-5 times faster than traditional heat conduction, the heat-affected zone is small, and deformation of the film is avoided. For example, Shanghai Junjingsai 35KW track heat sealing machine can complete 1 meter seam welding in 2 seconds.
Track travel mechanism
The equipment is equipped with a track system driven by a servo motor, with a welding speed of 1-7 meters/minute, supporting straight line, arc and three-dimensional curved surface welding.
Case: Dongguan Rili HR-25KWA equipment achieves 800 square meters of welding per day in aerospace engineering, with an efficiency increase of 40%.
Closed-loop feedback control system
The welding temperature is monitored in real time through an infrared thermometer, and the power output is automatically adjusted in combination with PLC to ensure that the temperature fluctuation is ≤±2℃.
Data: The actual measurement of Puxiong PXMS-A07P equipment shows that closed-loop control increases the welding qualification rate from 92% to 98.5%.
3. Application scenarios and industry cases
Inflatable amusement equipment field
Case: A certain amusement equipment factory in Guangzhou uses Puxiong's fully automatic track-type PVC membrane heat sealing machine to achieve seamless welding of large inflatable castle PVC membrane materials, with an airtightness of 0.3L/(m²·h), which complies with the EU EN14960 standard.
Technical requirements: welding strength ≥ 80% of the parent material, tensile strength ≥ 25MPa.
Membrane structure building field
Case: A certain sports stadium in Beijing uses Puxiong's PXMS-A07P equipment to complete the welding of 12,000 square meters of PVC membrane materials, with a wind pressure resistance of 10kPa.
Innovation: The use of dual-track synchronous welding technology reduces the number of seams by 40% and improves the aesthetics.
