Embodiment Construction
[0015] Such as figure 1 As shown, the present invention includes a hinge support 4 fixed on the outside of the fully covered machine head 2, a connecting rod 6 hinged on the hinge support 4, a counterweight 7 mounted on the connecting rod and mounted on the Describe the hole pin wheel 3 at the end of the connecting rod. The end of the connecting rod 6 has a shaft hole 8, which is hinged to the shaft hole 5 of the hinge support 4 through a hinge shaft. In the present invention, a preferred embodiment is that a chute is provided on the connecting rod, and the counterweight 7 is slidably engaged in the chute, so that the position of the counterweight slider can be adjusted. Needling pressure of the perforator wheel 3. The perforator wheel 3 is provided with needles at intervals on the outer edge of the wheel, and the wheel shaft is connected to the end of the connecting rod.
[0016] In order to perforate various PP pipes with different thicknesses, the connecting rod can be d...

The invention discloses a totally encapsulated exhaust unit of wall pipes in polyethylene winding structures. The exhaust unit comprises a hinge pedestal, a connecting rod, a counter weight block and a hole breaking needle wheel, wherein the hinge pedestal is fixed outside of a totally encapsulated machine head, the connecting rod is hinged to the hinge pedestal, the counter weight block is arranged on the connecting rod, and the hole breaking needle wheel is arranged at the end of the connecting rod. According to the totally encapsulated exhaust unit, the hole breaking needle wheel is mounted on the totally encapsulated machine head through the connecting rod and the hinge pedestal, the hole breaking needle wheel and an encapsulated propene polymer (PP) pipe operate synchronously, the counter weight block provides a downward pressure for the hole breaking needle wheel to enable a needle on the needle wheel to complete piercing, equidistant hole breaking is achieved, and the pieced PP pipe is discharged and accumulated in air between an encapsulating belt and the PP pipe during a winding and lapping process, so that bubbles on a lapping root portion of the PP pipe are eliminated, totally encapsulated PP pipe has a smooth, flat and good appearance in a winding process, and an effect on improving the product quality is achieved. According to the totally encapsulated exhaust unit, the structure is simple, the operation and the regulation are convenient, the totally encapsulated exhaust unit is well combined with an encapsulating process and a winding process, and a continuous processing process of complete processes of PP pipe encapsulating molding, hole breaking, air exhausting and winding is completed.
Description
technical field [0001] The invention relates to the technical field of plastic pipe processing, in particular to a polyethylene winding structure wall pipe fully-coated exhaust device for production equipment for large-diameter skeleton pipe high-density polyethylene winding structure wall pipes. Background technique [0002] At present, the PP pipe full covering process of large-diameter skeleton pipe high-density polyethylene winding structure wall pipe production equipment has improved the status quo of the seam of the covering tape in the form of the half-covered head, and improved the PP pipe torsion during the winding process. The exposed defect of the bare pipe caused by the seam offset of the covering tape improves the process quality and appearance effect of the pipe product. However, in the actual production process, when the PP pipe enters the coating core film, part of the air will be brought in, so that after the fully covered PP pipe is formed, in the process o...
