Abstract

The invention discloses a winding pipe coating film exhausting device. The winding pipe coating film exhausting device comprises a handpiece, and further comprises a connecting plate, a support plate, a pin wheel, a rotating shaft and a bearing, wherein the support plate is connected with the handpiece; the connecting plate is connected with the support plate through bolts; the bearing is installed into an inner hole of the pin wheel; the rotating shaft is installed into an inner hole of the bearing; the pin wheel is connected with the connecting plate through the rotating shaft; 8 steel pins which are uniformly distributed circumferentially are arranged on the excircular surface of the pin wheel; a long waist-shaped hole is formed in the connecting plate; two screw holes are formed in the support plate; the inner hole of the pin wheel is in transition fit with the excircular surface of the bearing; the inner hole of the bearing is in transition fit with the excircular surface of the rotating shaft. The winding pipe coating film exhausting device is simple in structure, convenient to adjust, good in exhausting effect, good in processing quality, low in cost and long in service life.

Description

technical field [0001] The invention relates to plastic pipe processing equipment, in particular to a wrapping film exhaust device for winding pipes. Background technique [0002] The existing high-density polyethylene (HDPE) winding reinforced pipe is processed by winding several winding pipes on the surface of the flat film, and the winding pipe is processed on the surface of the PP (polypropylene) pipe through a coating process. It is made of PE coating film. Since the PP pipe may be stored in a relatively humid or high-humidity environment or be exposed to rain during transportation, there is more moisture on the surface. The coating process is performed on this PP pipe. When the water on the surface of the PP pipe is heated and vaporized, some hollow "bulges" will appear in the winding pipe. If the winding pipe with "bulges" is wound on a flat film, the "bulges" will be cooled after cooling. Irregular wavy traces are formed on the flat film, which seriously affects the...
