Water immersion type plastic pipe sizing device

Abstract

The invention discloses a water immersion plastic tube diameter setter, which comprises a hollow fixed disc connected on the side wall of a cooling groove while one side of the hollow fixed disc is mounted with a laminated base. The axial outside of the laminated base is mounted with a water flux adjusting disc whose middle is disposed with a plastic tube inlet, a constant-diameter sheath is mounted between the laminated base and the water flux adjusting disc, while the outlet of the constant-diameter sheath is through the laminated base and the hollow fixed disc and the inlet is relative to plastic tube inlet. The water flux adjusting disc is disposed with a water inlet communicated with the cross between the plastic tube inlet and the inlet of the constant-diameter sheath. The laminated base is parallel mounted with a support rod at same direction with the outlet of the constant-diameter sheath, and the support rod is sheathed with laminated pads whose center is arranged with a tube constant-diameter opening same as the constant-diameter sheath. The inventive tube and device have high cooling speed and two times of improved producing efficiency.

Description

technical field [0001] The invention relates to a water-immersed plastic pipe sizing device for a plastic pipe extruder. Background technique [0002] At present, the plastic pipe vacuum sizing sleeve used in the plastic industry generally adopts the spray method, and the vacuum groove on the sizing sleeve is disconnected, which prevents the pipe from being continuously and uniformly cooled on the 360-degree circumference of the sizing sleeve , because the cooling rate cannot keep up, the production speed of the pipe is affected, and the production cost of the pipe is increased. At the same time, the longer the plastic pipe stays in the extruder, the lower the performance of the pipe. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a water-immersed plastic pipe sizing device with fast cooling speed and high production efficiency. [0004] In order to solve the above technical problems, the present invention includes a h...
