preparation is performed before production, and the inner frame 5 is vertically placed on the bottom plate 75 using a lifting device and is fitted into a fixed position with the positioning groove 751. Then, the four rollers 6 are spliced along the inner frame 5 to form a cylindrical structure, and two adjacent rollers 6 are manually fixed by bolts 621 from the inside of the inner frame 5.

The plastic raw material is put into a bin 22 of an extruder 2, the plastic raw material is extruded into a strip 8 with a required section shape under the action of the extruder 2, and the strip 8 is cooled and shaped by a vacuum cooling shaping box.

The winch 43 is activated to lower the slide 44 along the guide 42 to the ground, the shaped strip 8 is rubberized by the rubberizer 3, the rubberized strip 8 passes through a deflector 46 on the strip laying machine 4, then the ends of the strip 8 are fixed on the rollers 6, and two adjacent strips 8 are fixed in abutment on the rollers 6.

The starting motor 71 works to drive the bottom plate 75 to rotate, the roller 6 fixed on the bottom plate 75 through the inner frame 5 rotates, the roller 6 enables the strip 8 to be wound on the roller 6 when rotating, and meanwhile, the roller 6 provides traction force for the strip 8 when rotating. When the motor 71 is operated, the hoist 43 is operated and slowly winds the hoist rope 431, so that the slider 44 moves upward along the guide rail 42. Here, the moving speed of the slide 44 is set to v, the width of the strip 8 is set to d, the rotation speed of the roller 6 is set to w, the time t =2 pi/w = N x d/v of one rotation of the roller 6, N is a multiple of the unit strip 8, and N may be 1, 2, 3, 4, etc.

Along with the slow rising of the sliding seat 44, the sliding seat 44 drives the strips 8 to be spirally and tightly laid on the roller 6, and two adjacent strips 8 are fixed after the glue solution is solidified, so that a large-diameter pipeline is formed on the roller 6. After the pipeline is produced, the strip 8 is cut off by using a tool, and then the inner frame 5, the roller 6 thereon and the pipeline are lifted away from the bottom plate 75 by using lifting equipment such as a crane, and the pipeline is pushed to be separated from one end of the roller 6.

Example two: a vertical large-scale pipeline winding forming device is shown in figure 12, and is different from the first embodiment in that a strip material laying mechanism 4 is omitted. Compared with the first embodiment, the advantages are that: when the difference in height between the drum 6 and the extruder 2 is small, the strip 8 fixed below the drum 6 presses the strip 8 above, so that the strip 8 spirals up along the drum 6. By omitting the strip laying means 4, the space occupied by the equipment is saved compared to the production of shorter pipelines.

Example three: a vertical large-scale pipeline winding forming device is different from the embodiment I in that a glue spreader 3 is omitted, a glue extruding machine is fixed on a sliding seat 44, and after a strip 8 is wound on a roller 6, the glue is extruded on two adjacent strips 8 by the glue extruding machine. The pin extruder may be a small plastic extruder, as desired.

The advantage of the second embodiment over the first embodiment is that the tape 8 is glued later in time, preventing the glue from setting in advance and causing the tape 8 to be not firmly bonded. In addition, the glue on the strip 8 is prevented from being stained with impurities or dropping to a working site to cause pollution in the transportation process.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
