Description

Technical Field

[0001] The utility model relates to the technical field of extrusion shaping, in particular to a shaping output device for extrusion discharging. Background Art

[0002] PPR pipe is type III polypropylene pipe. PPR pipe is the replacement product of galvanized pipe, UPVC water supply pipe, aluminum-plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. It has the advantages of small conveying resistance, high ring height and high temperature resistance, thus becoming the main force of water pipe material. PPR pipe is generally produced by extrusion processing. After extrusion, it needs special shaping device to process it.

[0003] A double vacuum water-cooled ultra-stable PE pipe shaping device disclosed in Chinese patent CN201720713491.3 extends the length of one cooling by two shaping box structures that can be tightly connected to each other. Moreover, the vacuum-sealed environment of the two shaping boxes has a larger vacuum range than that of a single shaping box, and a larger uniform pressure range for the same pipe, thereby improving the overall uniformity of the pipe. However, the double vacuum water-cooled ultra-stable PE pipe shaping device does not cut the PE pipe after cooling and shaping. For some pipes that need to be cut after production, the pipes are easily bent during transmission and output after being cut, which affects the shaping effect. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a shaping output device for extruded materials, which effectively solves the shortcomings of the prior art.

[0013] Optionally, a support frame is provided below the output table, and the support frame is rotatably connected to one side of the output table. A third electric push rod is provided below the output table. The length of the output table is equal to the length of the cut pipe. When a whole pipe is placed on the output table, the third electric push rod is started to lift the output table to a certain angle and then reset it.

[0014] Optionally, a pipe collection rack is provided on one side of the support frame, the length of the pipe collection rack is adapted to the length of the output platform, the top of the third electric push rod is not connected to the bottom of the output platform, and the output platform is in a horizontal state when the third electric push rod is retracted.
