Abstract
The invention belongs to the field of PVC pipeline connecting equipment, and relates to a high-precision PVC pipeline automatic welding device. The device comprises a driving ring hooped on the outer wall of a pipeline, the driving ring is connected with a hot air pipe, an air outlet of the driving ring is located between a pipeline welding seam and a PVC welding piece, the driving ring is provided with a welding assembly through a connecting rod mechanism, and the welding assembly comprises a mounting bottom plate and a rolling mechanism on the rear side. The two groups of hot air pipes are positioned on two sides of the welding seam; the rolling mechanism comprises a rolling ball and can roll the PVC soldering lug. The connecting rod mechanism is parallelogram-shaped and provided with a reset spring and a damping rod. The rolling mechanism is further provided with a lifting assembly which can control the rolling balls to be lifted or put down. The driving ring is composed of a seat ring and swing rings hinged to the two sides, and the driving roller can adapt to different pipe diameters. The device can automatically rotate at a constant speed along a welding seam, realizes constant-speed heating of the welding seam, ensures melting and uniform fusion of a contact surface, avoids defects such as insufficient welding and the like, and improves the welding precision.
