Description
The present invention relates to a sewer pipe forming apparatus using an uneven wall formed by regulating the width of an extrusion belt. More particularly, the present invention relates to a sewer pipe forming apparatus using an uneven wall formed by adjusting the width of an extrusion belt, W "-shaped concavo-convex water wall is supplied to the inner diameter hollow of the profile to be formed into a unit with the profile, and the profile is spirally fed to the winder And more particularly, to a sewage pipe forming apparatus using a concavo-convex water-receiving wall that adjusts the width of an extrusion belt to be formed by feeding a joint member.
Conventionally, a profile having a baffle in the hollow of a double wall sewer pipe has been provided in various forms.
As for the double-walled pipes provided with such conventional awnings, a reinforcing member having a cavity formed therein is supplied through a synthetic resin extruder as a "method of forming a synthetic resin pipe having improved strength" of the prior application No. 0398452, and at the same time, In the case of manufacturing a synthetic resin pipe by spirally connecting the reinforcing member
A method of forming a synthetic resin tube having an improved strength for integrally fusing a high strength film having a width of 5 to 10 cm after the forming process of a synthetic resin pipe for forming a synthetic resin pipe by connecting the fitting material in a spiral form in a molding machine, However, such a structure of the reinforcing member (profile) is possible in the design drawing. Therefore, there are many problems in using the reinforcing member as a scaffold in the actual reinforcing member molding. That is, in order to form the same as the reinforcing member of the registered patent No. 0398452, the synthetic resin melted by the molding frame is extruded and cooled. In the hollow portion of the reinforcing member, "+", "◇", " The reinforcing member is cooled when cooled by the cooling water after passing through the molding die, and is time-hardened to be cured to cause warping, and the inner wall of the double wall tube is bent to generate friction. Particularly, Patent No. 0398452 relates to a method of forming a synthetic resin pipe having improved strength, and more particularly, to a reinforcing member for increasing the strength of a synthetic resin pipe, which can not be used as a water wall of a hollow tube. There is a problem that the fluid moves along the hollow tube.
In addition, Korean Patent No. 0458608 entitled "Structure of double wall sewage pipe" flows through a sewer pipe
Even if the wastewater flowing into the hollow is introduced into the hollow, it is prevented from further movement in the hollow portion, thereby preventing contamination of the soil and groundwater due to leakage of the wastewater due to damage of the outer wall of the pipe The double wall sewage pipe is provided with a supply step of supplying a raw material for synthetic resin to a raw material supplying part, a feeding step of heating and feeding the supplied raw material in a liquid phase and simultaneously feeding the raw material, a resin pipe having a hollow part In a conventional manufacturing process in which a double wall sewage pipe is manufactured through an extrusion step in which the extruded resin pipe is extruded and a coiling step in which the extruded resin pipe is wound in a spiral direction, By forming and continuously supplying a raw material for a sheet to be extruded from a separate extruding portion, And a capping film is provided on a hollow portion formed in a spiral shape along the circumferential wall of the main body. Regarding the construction of the profile, the " W "shaped cap film is formed inside the resin tube to form a profile, Since the forming rollers of the gear form are rotated to rotate when the forming film is formed by using the gear form forming rollers in the form of gears when forming the strips, the gears and the gears come into contact with each other, There was a problem in that it was molded.
In order to prevent the above drawbacks, Patent No. 0894522 discloses a dual wall pipe used as a sewer pipe, a water pipe, a drain pipe, a gut pipe, etc., in which a square hollow pipe is spirally wound and formed into a cylindrical double wall pipe The inner wall of the hollow tube of the synthetic resin square is worn by the vibration and wave of the fluid flowing inside (tap water, sewage, sewage, etc.) and the flow of the fluid during use, and the fluid flows into the hollow portion and moves The present invention provides a watertight film for preventing the movement of a fluid by joining a water wall member in a hollow tube and enhancing the strength of a double wall pipe, and the water wall molding machine is constituted by a first molding wheel and a second molding wheel in the form of a disk, A plurality of forming pins are provided on one surface of the forming wheel of the forming wheel, Sikimeuro continuously repeatedly molded as was to maintain the strength against the load of a double wall pipe is used as a drainpipe, ohsugwan, drain, constant pipe, water pipe, such as pipe storage tank.
However, such a conventional a water pipe wall can only block the flow of fluid moving inwardly in all of the upper, lower, left, and right sides of the inner diameter of the profile. However, In this case, since the profile is supplied to the inner diameter of the molding, the fusion is not normally performed on the slope and the order function can not be normally performed. In the process of being extruded from the extruder, However, since the width of the water wall is not constantly provided, the water wall function can not be normally performed.
In addition, since the conventional double wall sewer pipe is fed and melted to both sides of the profile, the joining member is supplied by extrusion to melt-bond the profiles, so that the joints corresponding to the widths or thicknesses of the profiles are supplied And the cost of the material is increased.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a double wall sewage pipe which is used as a sewer pipe, an upper pipe, a drain pipe, And the width and thickness of the extruded band can be adjusted.
Another object of the present invention is to provide a method of forming a profile by regulating the width and thickness of an extrusion belt and correcting the width again so as to form a profile while supplying the irregular water wall to melt the irregular wall on the inner surface of the profile, To be able to do so.
The present invention is connected to a second extruder for extruding a profile such that the uneven wall is supplied to the hollow and the slope is fused at the front of the uneven wall forming apparatus for forming the "W" type uneven wall by supplying the extruded strip from the first extruder And a cutting device for forming a water wall sewer pipe and cutting the pipe into a predetermined length by supplying a joining member from a joining nozzle provided in front of the second extruder in a winding device for feeding a profile by pulling a profile in a profile molding device, a cooling device and a pull- A sewage pipe forming apparatus using a concavo-convex water wall,
A width adjusting device for adjusting the width and the thickness of the slab by a first rolling device so that the slope is fused in the hollow in the process of feeding the slab, and a power supply device at the rear;
A width cutting device having a transfer cylinder for adjusting the position of the cutting knife on both sides so as to adjust the width of the extrusion belt to the right side of the width adjusting device;
The upper and lower protrusions and protrusions provided on the pair of upper and lower wheels are rotatably engaged with the upper and lower protrusions and recesses to form a "W" -shaped concave and convex wall, .
