나선관 성형용 압출도관의 접합장치{APPARATUS FOR SPIRAL CAST PRESSING CONDUIT}APAPATUS FOR SPIRAL CAST PRESSING CONDUIT

본 고안은 각종 액상의 물질을 이송하는데 사용되는 큰 직경을 갖는 합성수지재의 나선관을 성형하기 위한 나선관 성형용 압출도관의 접합장치에 관한 것으로, 더욱 상세하게는 압출장치, 성형다이스, 냉각장치 및 권취장치로 구성되는 나선관 제조장치에 있어서, 상기 권취장치를 구성하는 권취드럼의 적정 둘레부로 다수의 송풍공이 뚫어져 형성되고, 별도의 가열장치와 송풍장치에 의해 작동되는 가열판을 적정 간격을 두고 코일형으로 감아 형성한 코일형가열장치에 의하여 상기 압출장치와 성형다이스 및 냉각장치를 거쳐 압출 성형되는 압출도관을 상기의 권취장치를 구성하는 권취드럼의 둘레부로 감겨져 형성된 코일형가열장치에 의하여 압출도관의 양측면을 용융시켜 접합함으로써 소정의 직경을 갖는 나선관을 성형하기 위한 것이다.The present invention relates to a splicing apparatus for forming a spiral tube for forming a spiral tube of a synthetic resin material having a large diameter used to transport various liquid substances, and more particularly, an extrusion apparatus, a molding die, a cooling apparatus, In the spiral tube manufacturing apparatus composed of a winding device, a plurality of blow holes are formed through a proper circumference of the winding drum constituting the winding device, and coils are spaced at appropriate intervals by a separate heating device and a heating plate operated by the blowing device. The extruded conduit is formed by winding the extruded conduit extruded through the extruder, the forming die, and the cooling device by a coil-type heating device wound into a shape around the winding drum constituting the winding device. It is for shaping a spiral tube having a predetermined diameter by melting and joining both side surfaces thereof.

종래에 나선관을 성형하기 위한 압출도관을 접합하기 위한 장치는 도5 내지 도6에 나타낸 바와 같다.Conventionally, an apparatus for joining an extruded conduit for forming a spiral tube is as shown in Figs.

압출장치(101), 성형다이스(102), 냉각장치(103) 및 권취장치(104)로 구성되는 나선관(106) 제조장치에 있어서, 상기 냉각장치(104)에 의해 냉각되어져 이송되는 압출도관(107)을 도6에 나타낸 바와 같이 압출도관(107)이 권취장치(104)를 구성하는 권취드럼(104a)에 감겨지면서 상기 권취드럼(104a)의 일측으로 형성된 접착제공급장치(108)에 형성된 노즐(108a)에 의하여 압출도관(107)의 양측면이 맞닿는사이로 연속적으로 접착제를 공급하여 줌으로서 상기 압출도관(107)이 서로 이웃하는 양측면이 접합되어 나선관(106)으로 성형되는 것이다.In the spiral pipe 106 manufacturing apparatus comprising an extrusion device 101, a molding die 102, a cooling device 103 and a winding device 104, an extrusion conduit cooled and conveyed by the cooling device 104. As shown in FIG. 6, the extrusion conduit 107 is wound around the winding drum 104a constituting the winding device 104 and formed on the adhesive supply device 108 formed on one side of the winding drum 104a. By continuously supplying an adhesive between both sides of the extruded conduit 107 by the nozzle 108a, the extruded conduits 107 are joined to both sides of the adjacent conduit to form a spiral tube 106.

즉, 종래의 나선관(106)은 냉각장치(103)에 의하여 냉각되어져 이송되는 압출도관(107)을 권취장치(104)에 형성된 권취드럼(104a)에 권취함으로써, 일정한 직경을 갖는 나선관(106) 성형되는데, 상기의 압출도관(107)이 권취드럼(104a)에 권취되기 직전의 맞닿는 부분에 노즐(108a)에 의하여 접착제를 공급하면서 권취함으로써, 서로 이웃하면서 권취되는 압출도관(107)이 접합된 상태의 나선관(106)이 성형된다.That is, the conventional spiral tube 106 is wound by the cooling device 103 by winding the extruded conduit 107 to the winding drum (104a) formed in the winding device 104, the spiral tube having a constant diameter ( 106. The extruded conduit 107 wound around each other by being wound while supplying the adhesive by the nozzle 108a to the contact portion just before the extruded conduit 107 is wound on the winding drum 104a is formed. The spiral tube 106 in the joined state is molded.

그러나 상기와 같은 접착제공급장치(108)에 형성된 노즐(108a)에 의하여 공급되는 접착제를 이용하여 압출도관(107)을 접합할 경우 접착제가 상기 서로 이웃하는 압출도관(107)의 양측면으로 일정하게 공급되기가 어려워 접착제가 뭍지 않는 부분이 생겨 완전하게 면접합이 되지 않고 나선관(106)이 성형된다.However, when bonding the extrusion conduit 107 using the adhesive supplied by the nozzle 108a formed in the adhesive supply device 108 as described above, the adhesive is constantly supplied to both sides of the adjacent extrusion conduit 107. It is difficult to form a portion where the adhesive is not broken, and the spiral tube 106 is molded without being completely interviewed.

이와 같이 성형된 종래의 나선관(106)은 수밀성에 문제가 따르는 것으로, 시공 후 어느 한 곳의 접착제가 뭍지 않아 접합이 되지 않은 미세한 구멍이라도 있을 경우 액체가 누수되는 문제가 있었다.The conventional spiral tube 106 formed as described above has a problem in watertightness, and there is a problem in that a liquid leaks when there is even a fine hole which is not bonded due to no adhesive at any one place after construction.

예로서 누수된 물질이 상수도와 같이 깨끗한 물이면 다소의 물의 손실이 있더라도 괜찮지만 오수이거나 혹은 유해물질인 경우 토양을 해치는 결과가 되어 결국 자연환경을 해치는 결과를 초래하게 되었던 것이다.For example, if the leaked material is clean water such as tap water, there may be some loss of water, but if it is sewage or harmful substance, it will damage the soil and eventually damage the natural environment.

본 고안은 나선관의 취약점인 누수의 문제점을 최소화시키고 동시에 나선관의 강성도 향상시키므로서 수밀성과 내압성을 동시에 만족시킬 수 있도록 본 고안을 구성하는 권취드럼의 적정 둘레부로 다수의 송풍공이 뚫어져 형성되고, 별도의 가열장치와 송풍장치에 의해 작동되는 가열판을 적정 간격의 코일형으로 감아 형성한 코일형가열장치에 의하여 냉각장치를 거쳐 압출 성형되는 압출도관의 이웃하는 접속부를 접착제의 공급이 필요없이 일체화로 접합시킬 수 있도록 한 나선관 성형용 압출도관의 접합장치를 제공하고자 함이다.The present invention minimizes the problem of leakage, which is a weak point of the spiral pipe, and at the same time improves the rigidity of the spiral pipe while simultaneously satisfying the watertightness and pressure resistance, a plurality of blow holes are formed in the perimeter of the winding drum constituting the present invention. The coiled heating device formed by winding the heating plate operated by a separate heating device and a blower in an appropriately spaced coil form is integrated into an integral part of the extrusion conduit extruded through the cooling device without the need for adhesive supply. It is an object of the present invention to provide a bonding apparatus for extrusion conduits for forming a spiral tube.
