Technical Field

[0001] The utility model relates to the technical field of pipe rounding machines, and specifically relates to a PE pipe rounding machine. Background Art

[0002] A PE pipe rounding machine is a device used in plastic pipe production, mainly for processing plastic particles or pellets into pipes with a specified diameter. This device is widely used in fields such as construction, water supply and drainage, etc.

[0003] After the PE pipe is extruded and formed, through the methods of spray water cooling and immersion water cooling, it requires a certain distance from extrusion to cooling and forming. During this period, when the pipe is moving, the drag wheel and the scraping blade support are used to ensure that the pipe moves in a straight line normally during cooling. However, due to the drooping of the pipe during high-temperature extrusion to cooling and forming and the buoyancy of water, the out-of-roundness of the pipe when it comes off the production line exceeds the standard, which affects the later construction quality.

[0029] Working principle: Insert the pipe between the round bars 502 between the fixed frame 3 and the movable frame 4. The pipe passes between the upper and lower groups of round bars 502, and the round bars 502 are used to round the pipe. The outside of the conveyor belt 501 is externally connected to a transmission device to drive the conveyor belt 501 to move and transport the pipe. The distance between the upper and lower groups of round bars 502 can be adjusted according to the size of the pipe. When adjusting the movable frame 4 upward, the user moves the transmission gear 604 into the rotating hole at the lower part of the through slot 9, and then rotates the transmission gear 604 to engage with the toothed plate 602, driving the toothed plate 602 to move on the support 2. After moving once, move the transmission gear 604 into the rotating hole on the right side of the through slot 9, and when continuing to move, move the transmission gear 604 to engage with the toothed plate 602 again, and so on. The toothed plate 602 drives the movable sleeve 601 and the movable frame 4 to move on the support 2, thereby adjusting the height of the upper round bar 502. When the toothed plate 602 moves, it pushes the latch 701 upward, and the latch 701 compresses the spring and contracts. After the toothed plate 602 stops moving, the spring 703 resets and clamps the latch 701 into the toothed plate 602 to limit the toothed plate 602, thereby limiting the movable frame 4 on the support 2. When it is necessary to lower the movable frame 4, pull the latch 701 to move the toothed plate 602 downward, and then clamp the latch 701 into the toothed plate 602 to limit it after the movement is completed.
