Screw pitch around formation be it is fixed nonadjustable, in certain occasions, when the reinforcing rib for needing big screw pitch, certainly will need to produce symbol again
Desired plastic shaped band is closed, i.e., plastic shaped band needs to redesign and processing, and such consumptive material is time-consuming, greatly increases into
This.
2) since tubing parietal layer is that directly had between the tubular lobes for including hollow cavity by the two sides of plastic shaped band
The connection sheet gap that winds and constitute, therefore formed between adjacent plastic shaped band two tubular lobes adjacent to each other
The saturation degree of bond degree and gluing bonding influences intensity, the sealing performance of tubing layer, if there are bubble or works in gluing
Skill reason makes adhesive property bad, for example, two tubular lobes side fusion position formed enhancing internal-rib be need squeeze
Pressure, the gap necessarily formed between two tubular lobes is the weak part of entire tubing, once there is defect, Jiu Huizhi
Connecing leads to leak.

Due to forming defect, the functional effect of the enhancing internal-rib of hollow reinforced rib is directly affected, because itself is at one kind
Unstable and firm state.
4) the enhancing internal-rib of hollow reinforced rib is heated is easy temperature distortion and wave height is caused to lose, and causes tubing
The reduction of ring stiffness.
It 5) is directly to be had between the tubular lobes for including hollow cavity by the two sides of plastic shaped band for tubing parietal layer
Connection sheet wind and constitute, by the gap that is formed between adjacent plastic shaped band two tubular lobes adjacent to each other into
Row bonding forms internal rib reinforcing outer ripple type plastic twining structured wall pipe, and plastic shaped band is that molding cooling is fixed
The product of type, therefore the welding between adjacent plastic shaped band two tubular lobes adjacent to each other belongs to cold welding, it should
Cold welding is the essential step and welding structure of the molding internal rib reinforcing outer ripple type plastic twining structured wall pipe, from
And it is low there are the low the shortcomings that being easy disconnected pipe of weld strength when cold welding molding, especially weld strength and cause " spring " existing
As.

The present invention is compared to 102305316 B of Chinese patent CN, internal rib reinforcing outer ripple type plastic twining structured wall pipe
And its manufacturing method can overcome its existing defect since forming principle is entirely different well.
Core of the invention is heterotypic strip and the reinforcing rib in it is that preforming are good, and melten gel etc. is located at abnormal shape
The bottom surface of band, therefore reinforcing rib is not heated directly and deforms and wave height is caused to lose, secondly internal-rib enhances irregular belt material
After being preheated, in the bottom-surface coated melt layer of the bottom muscle of internal-rib enhancing irregular belt material, and the sheet material for forming tubing layer is
Band heat is carried out continuous winding and is overlapped to form cylinder tubulose tubing layer, while bottom by wrapping machine after coming out from sheet former
The internal-rib enhancing irregular belt material that face is coated with melt layer follows winding, the outside wall surface of cylinder tubulose tubing layer by melten gel and
Profile shapes bottom fits closely, and rolls and cools down, and ultimately forms winding-type internal-rib bellows.
As it can be seen that there are following advantages by the present invention:

Connection sheet between the tubular lobes of hollow cavity, which is wound, to be constituted, hollow since plastic shaped band is that preforming are good
The screw pitch being wound between reinforcing rib is fixed nonadjustable；And the present invention is that heterotypic strip follows winding, therefore follows and twine
Can change around screw pitch, so as to adapt to big screw pitch reinforcing rib occasion, do not need to produce satisfactory plastics again
Heterotypic strip, i.e., plastic shaped band needs to redesign and processing, time saving in this way to save trouble, and substantially reduces cost.
2) tubing parietal layer described in 102305316 B of Chinese patent CN is directly by the two sides of plastic shaped band with interior
Connection sheet between tubular lobes containing hollow cavity, which is wound, to be constituted, therefore two pipes that adjacent plastic shaped band is adjacent to each other
The bond degree in the gap formed between shape protrusion and the saturation degree bonding of gluing influence intensity, the sealing performance of tubing layer, such as
There are bubbles or technological reason to make adhesive property bad in fruit gluing, such as the side of two tubular lobes fuses position
The enhancing internal-rib needs of formation squeeze, and the gap necessarily formed between two tubular lobes is the weak point of entire tubing
Position, once there is defect, will directly result in leak；And the present invention, which forms tubing inner sheet, to be carried out under thermal welding state,
Therefore the defect of above-mentioned leak is not present.Tubing of the present invention inner sheet refers to sheet material.
3) the enhancing internal-rib of hollow reinforced rib described in 102305316 B of Chinese patent CN is by the side of two tubular lobes
Face fusion position and gluing are constituted together, due to forming defect, directly affect the function of the enhancing internal-rib of hollow reinforced rib

Heterotypic strip, in the production process of entire winding-type internal-rib bellows, reinforcing rib is not heated directly, and is one
It rises and is molded in heterotypic strip, therefore be constantly in stable and firm state.
4) the enhancing internal-rib of hollow reinforced rib described in 102305316 B of Chinese patent CN is easy temperature distortion and leads to wave
Line height loss causes the reduction of the ring stiffness of tubing；And the present invention is in the production process of entire winding-type internal-rib bellows
In, thermal welding state is to occur between the bottom surface of heterotypic strip and the outer surface of tubing layer, therefore is not present in drawbacks described above,
Reinforcing rib i.e. in heterotypic strip is notheated deformation and wave height is caused to lose, and causes the reduction of the ring stiffness of tubing.
It 5) is directly to be had by the two sides of plastic shaped band for tubing parietal layer described in 102305316 B of Chinese patent CN
There is the connection sheet winding between the tubular lobes for including hollow cavity to constitute, by adjacent to each other two of adjacent plastic shaped band
The bonding that carries out in the gap formed between tubular lobes forms internal rib reinforcing outer ripple type plastic twining structured wall pipe, and plastics
Heterotypic strip is the product of molding cooling and shaping, thus adjacent plastic shaped band it is adjacent to each other two tubuloses it is convex
Welding between rising belongs to cold welding, which is that the molding internal rib reinforcing outer ripple type plastic twining structured wall pipe must
Indispensable step and welding structure, so that there are the low the shortcomings that being easy disconnected pipe of weld strength when cold welding molding, especially
Weld strength is low and causes " spring " phenomenon；And when present invention winding sweat soldering, the sheet material come out from sheet former is direct
It carries out continuous winding by wrapping machine and overlaps to form cylinder tubulose tubing layer, while preheated bottom-surface coated has melt layer
The internal-rib enhancing irregular belt material follows winding, and the outside wall surface of such cylinder tubulose tubing layer is tight by melten gel and profile shapes bottom
Closely connected conjunction rolls and cooling, ultimately forms winding-type internal-rib bellows, therefore the present invention is different from above-mentioned cold welding and formed
Journey, thus there are the low the shortcomings that being easy disconnected pipe of weld strength when cold welding molding, especially weld strength is low and cause " bullet
Spring " phenomenon.
In addition, the bottom of irregular belt material of the present invention is the bottom muscle with arcuate structure, acts on as follows: can be solved when winding different
Shape material unilateral the phenomenon that being easy to appear alice when being wound by helical angle；Melten gel is not allowed when increasing melten gel contact area and winding
Easily being extruded disappearance causes adhesive effect poor；For example plane bottom muscle, profile shapes is easy winding bottom due to bending deformation when winding
There is raised phenomenon, causes band bottom since inclination to the left or to the right occurs in middle part contact, to product appearance and melt adhesive
All very unfavorable, bottom structure of the present invention with arc can be solved the problem above-mentioned effectively；When producing heavy caliber pipe, due to interior
Muscle is thicker, it is cooling it is difficult to ensure that, it may appear that muscle occurs bending and deformation situation in reinforcing, and arcuate structure bottom muscle can nature in winding
It is exceptionally straight down, there is stretching to muscle in reinforcing to reduce interior muscle curvature.
In short, internally finned tube described in 102305316 B of Chinese patent CN is spliced for profile, once there is cold welding appearance
Be not bonded or it is false viscous, just directly can leak, and inner sheet, that is, sheet material in the present invention is that hot wind is formed by overlapping, even if this hair
There is vacation and glues in bright irregular belt material, and drainage will not occurs, because internal layer, that is, tubing layer has become reliable protective layer.
Certainly, the present invention compared with the existing technology in tubing, such as carat pipe, product of the invention has internal-rib, i.e., logical
The internal-rib that the irregular belt material of welding is formed is crossed, is continuous production overall structure, internal-rib described in 102305316 B of Chinese patent CN
Pipe is equally that profile is spliced, and is not internal-rib overall structure.Carat pipe uses PP bushing pipe, discontinuous to produce, and is not whole
Welding, PP skeleton are not bonded；The bottom cambered surface of irregular belt material product of the present invention is bonded, and bond area is big, and carat pipe is round bone
It being wound after frame cladding, round bond area is small, and there are dead angles on tubing ripple both sides, and it is easy backfill leakiness and completes to cave in, and in
Internal-rib described in 102305316 B of state patent CN is spliced by profile side, and completely cold welding, bond area are difficult to increase, and is glued
The volume of the welding glue connect is difficult to increase, if to increase, needs to design counter structure, and otherwise welding glue is difficult to form, and
Once it is viscous vacation occur, will leak.The production method and the present invention of internally finned tube described in 102305316 B of Chinese patent CN are complete
Difference, the production method and the present invention of carat pipe are entirely different.The technical problems to be solved by the invention, technical concept and
Made product is different, therefore 102305316 B of Chinese patent CN and carat pipe there is no the technical inspiration combined and move
Machine.
