Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic pipes, in particular to a winding method for a joint rubber ring. Background Art

[0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is mainly composed of resin-based glass fiber wound layer by layer on a rotating core mold according to process requirements, and quartz sand is laid between the fibers as a sand layer.

[0003] In order to continuously splice FRP pipes, the two ends of the pipe are generally made into a male end and a female end respectively. During installation, the male end of one pipe is inserted into the female end of the other pipe when splicing; in order to ensure the sealing of the splicing position, the inner wall of the female end is made into a long cylindrical rubber ring; the rubber ring is relatively long and must be firmly integrated with the pipe body. Multiple grooves need to be provided on the outer wall of the rubber ring to allow the material of the pipe body to fit into the groove; when the pipe body is produced, multiple layers of glass fiber are generally wound and mixed with resin and quartz sand.

The second cylinder 1033 is controlled to rotate the rotating disk 1035 inside the fixed disk 1031, and the rotating disk 1035 is rotated 90 degrees to drive the yarn row a to be horizontal. The second yarn bundle passes through the inner side of the yarn guide frame 8 and then passes over the top of the yarn guide roller 78 to enter the inner side of the cutting roller 74 and the pressure roller 75. The cutting roller 74 and the pressure roller 75 are driven by the action of the driving motor 77 to cut the second yarn bundle into short fibers. The cut short fibers are The chopped fibers fall on the dispersion plate 96, and the vibrator 95 makes the chopped fibers pass through the dispersion plate 96 and fall on the inner walls of the long side plate 91 and the short side plate 92, and then fall on the yarn row a. The side of the yarn row a with the chopped fibers faces the rubber ring 1 to be wound around the rubber ring 1.
