Prepreg band guide-in composite device and working method thereof

Abstract

The invention relates to a prepreg band guide-in composite device and a working method thereof. The prepreg band guide-in composite device comprises a transversely-arranged rotary mold core and a rack doing reciprocating motion in the length direction of the mold core. A plough type pressing head structure and a needle comb type exhaust structure are arranged on the rack. The plough type pressing head structure comprises a stainless steel heat conduction pressing head close to the surface of the mold core and a heater arranged above the stainless steel heat conduction pressing head. A prepreg band continuously guided in and wound around the mold core is arranged between the stainless steel heat conduction pressing head and the heater in a penetrating manner. The stainless steel heat conduction pressing head is provided with an arc forward-stretching piece attached to the surface of the mold core. A second heater is arranged in the stainless steel heat conduction pressing head. The needle comb type exhaust structure is provided with multiple spikes arranged side by side. A needle comb penetrates into the prepreg band wound around the mold core. According to the prepreg band guide-in composite device, bubbles generated in the prepreg band attachment process can be punctured easily, and the situation that the hidden danger of cracking in the later use process is caused due to the fact that the bubbles exist in a pipe wall can be avoided easily.

Description

[0001] Technical field: [0002] The invention relates to a prepreg tape introduction composite device and a working method thereof. [0003] Background technique: [0004] Plastic pipe is made of plastic resin as raw material, adding stabilizer, lubricant, etc., and extruding in the pipe making machine by "plastic" method. There are mainly polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, ultra-high molecular weight polyethylene pipes, etc. Plastic pipes are mainly used for water delivery, but the current plastic pipes are limited in diameter and cannot be made into large pipe diameters. At present, some large-scale water transmission projects require large-diameter or super-large-diameter pipes for water transportation, but currently limited by technical equipment, etc., the pipe wall of the currently produced large-diameter pipes has holes, which is easy to be damaged during use. There is a fatal flaw of cracking and water seepage...
