Embodiment Construction
[0015] Such as figure 1 and figure 2 As shown, the new spiral plastic rib pipe production device includes a housing 1, a rotating sleeve 2 and a pipe body shaping sleeve 3. The pipe body shaping sleeve 3 is fixedly installed on the housing 1, and the pipe body shaping sleeve is sleeved There is a mandrel 10, a cylindrical gap is provided between the outer peripheral surface of the mandrel and the inner wall of the tube calibrating sleeve, the mandrel 10 is fixedly connected with the housing 1, and the housing 1 is also A rotary sleeve 2 that rotates relative to the tube body sizing sleeve 3 and the housing 1 is installed in rotation. There is at least one annular trough 4 extending along the circumferential direction of the tube body sizing sleeve 3. In this embodiment, the outer surface of the tube body sizing sleeve 3 is provided with two annular troughs. Specifically, In the implementation process, one or more than two annular troughs can also be set, and a feed channel ...

The invention relates to a production device of novel helical plastic reinforced pipes. The production device comprises a casing, a rotary sleeve and a pipe body shaping sleeve, wherein the pipe body shaping sleeve is fixedly mounted on the casing, a core rod is arranged in the pipe body shaping sleeve in a sleeving manner, and the core rod is fixedly connected with the casing; the rotary sleeve is also mounted on the casing in a rotating manner, and sleeves the outside of the pipe body shaping sleeve; one or more annular material grooves are formed in the outer surface of the pipe body shaping sleeve; feed channels are also formed in the pipe body shaping sleeve, and the other ends of the feed channels extend out of the casing; material guiding channels in one-to-one correspondence with the annular material grooves are formed in the inner surface of the rotary sleeve, openings in the first ends of the material guiding channels mutually communicate with the annular material grooves, openings in the second ends of the material guiding channels communicate with the inner cavity of the pipe body shaping sleeve, and a feed opening mutually communicating with the inner cavity of the pipe body shaping sleeve is formed in the casing. Plastic reinforced material liquid enters the material guiding channels from the annular material grooves and then is drained from the openings in the second ends of the material guiding channels to be inserted into the pipe body shaping sleeve, at the same time, pipe body material liquid enters a barrel-shaped gap between the pipe body shaping sleeve and the core rod from the feed opening, extruding and shaping of pipe bodies are performed, and in this manner, the plastic reinforced liquid is drained from the openings in the second ends of the material guiding channels and bonded on the outer surfaces of the pipe bodies.
Description
technical field [0001] The invention relates to a production device for a spiral plastic-reinforced pipe. Background technique [0002] The existing production technology of spiral plastic rib pipe is to extrude sheet-shaped pipe body and strip-shaped plastic rib first, and then perform spiral bonding on the rotating machine head. Because the pipe body rotates as a whole during the production process, it is necessary to use a long Producing at a distance from the water tank takes up a lot of space. For example, to produce a 30-meter-long plastic-reinforced spiral pipe, the existing technology requires a 30-meter-long water tank to produce. The production process is difficult, the requirements for material selection are high, the scrap rate is high, and limited by the rotating machine head, it is impossible to produce small-diameter plastic rib tubes, and the bonding seams formed after the sheet tubes are bonded result in unstable product quality .
