PVC Panel Extrusion Line For Grating Boards

PVC Panel Extrusion Line is equipped with an SJZ55/110 conical twin-screw extruder, the line supports 24-hour continuous operation. Material is efficiently conveyed and plasticized through screw rotation, ensuring high output capacity of approximately 80 to 140 kg/h.

The vacuum calibration table creates a negative pressure environment to precisely shape the profile cross-section using a calibration mold. This ensures dimensional tolerances of the grating board are controlled within ±0.2 mm. An integrated recirculating cooling system, combined with grooved water channels along the mold cavity walls, significantly enhances heat exchange efficiency and increases the production line speed.

The caterpillar-type haul-off unit features a segmented clamping design with multiple track sets, offering a wide adjustable range of traction force. Driven by a frequency-controlled motor and synchronous belt transmission, it ensures precise speed control, preventing slippage or stretching deformation during the haul-off process. The tracks are covered with wear-resistant rubber or silicone materials, and equipped with pneumatic or spring-loaded floating mechanisms. This allows automatic adaptation to various grating board cross-sections, ensuring even clamping force distribution and avoiding surface marks or damage on the profile.

The lift-blade cutter is driven by a servo motor, enabling high-precision lifting and cutting. It achieves a positioning accuracy within ±0.1 mm and maintains cutting length tolerance within ±1.5 mm.

The robotic arm operates according to preset programs and parameters to accurately grasp various products output from the extruder. It significantly improves the accuracy and consistency of stacking.
