The invention discloses a plastic
pipe for industrial dust collection and a preparation method thereof. The plastic
pipe comprises a dust collection plastic
pipe, wherein the dust collection plastic pipe is made of linear low-density
polyethylene thermoplastic as a
raw material through a
thermoplastic technology, and a
welding port is formed in the end of the dust collection plastic pipe.
Fusion welding ports of two dust collection plastic pipes are placed on
fusion welding equipment in a left-right alignment mode, a rotating inner
barrel is driven to rotate through the transmission effect of a belt, and due to the thread relation between the rotating inner
barrel and a tightening sliding
barrel, the tightening sliding barrel rotates outwards, so that an elastic pressing plate at the outer end of the rotating inner barrel is extruded, a fixing clamping ring at the outer end of the elastic pressing plate is fixedly clamped outside the plastic pipe, a clamping cotton
cushion is bonded to the inner ring wall of the fixing clamping ring, the plastic pipe is well protected, the situation that the fixing clamping ring slides relative to the plastic pipe and scratches the plastic pipe is avoided, meanwhile, by arranging the clamping cotton
cushion, the
friction force between the clamping cotton
cushion and the plastic pipe is increased, and therefore the plastic pipe is driven to rotate synchronously.
