상기 상부플레이트(20)와 하부플레이트(30)는 개별적으로 승강 가능하다. 즉, 메인실린더(21)에 의해 전체가 하강함과 함께 보조실린더(31)의 작동으로 하부플레이트(30)만 독립적으로 하강하는 구조를 가진다.The upper plate 20 and the lower plate 30 can be elevated individually. That is, the whole cylinder is lowered by the main cylinder 21 and the lower plate 30 is independently lowered by the operation of the auxiliary cylinder 31.

그리고, 상기 하부플레이트(30)의 하측에는 다수의 열풍융착노즐(40)이 설치되며, 이 각각의 열풍융착노즐(40)의 일측에는 열풍실린더(44)가 결합된다.A plurality of hot air fusion nozzles 40 are installed below the lower plate 30, and hot air cylinders 44 are coupled to one side of each of the hot air fusion nozzles 40.

그 후, 열풍실린더(44)의 작동에 의해 열풍융착노즐(40)이 이동하고, 이 열풍융착노즐(40)은 제 1분사유로(43a), 제 2분사유로(43b) 및 중앙분사유로(43c)의 3방향으로 고온의 에어를 분사함으로써 피가공물을 가열한다. 이때, 피가공물(L)의 양측 및 중앙으로 고온의 에어가 분사됨으로써 피가공물(L)에 대한 가열 작업이 원활하게 진행된다.Thereafter, the hot air fusion nozzle 40 is moved by the operation of the hot air cylinder 44, and the hot air fusion nozzle 40 is moved to the first injection passage 43a, the second injection passage 43b and the central injection passage ( The workpiece is heated by blowing hot air in three directions of 43c). At this time, by heating the hot air to both sides and the center of the workpiece (L), the heating work on the workpiece (L) proceeds smoothly.

가열이 종료되면 열풍융착노즐(40)은 후퇴하고 보조실린더(31)의 작동으로 하부플레이트(30) 및 이에 연결된 열풍실린더(44)는 상승하게 된다.When the heating is completed, the hot air fusion nozzle 40 is retracted and the lower plate 30 and the hot air cylinder 44 connected thereto are raised by the operation of the auxiliary cylinder 31.

이어서 융착툴(50)이 작업위치로 이동하여 가열된 피가공물(L)을 가압 융착하게 되고, 작업이 완료되면 다시 후퇴함과 동시에 메인실린더(21)에 의해 전체가 상승하여 다음 작업을 준비하게 된다.Then, the welding tool 50 moves to the working position to pressurize and weld the heated workpiece L, and when the work is completed, the welding tool retreats and the whole is raised by the main cylinder 21 to prepare for the next work. do.

그 후, 피가공물(L)을 냉각하여 배출함으로써 피가공물을 열풍 융착하기 위한 일련의 과정이 완료된다.Thereafter, a series of processes for hot air fusion welding of the workpieces are completed by cooling the workpiece L and discharging it.

이상에서 설명한 바와 같이, 본 발명에 따른 열풍융착노즐에 의하면, 열풍융착노즐의 내부에 양측 뿐만 아니라 중앙에도 분사유로를 형성하여 피가공물에 고온의 에어를 3방향으로 분사함으로써 피가공물의 안정적인 열풍 융착이 가능하도록 하고, 이에 따라 융착 불량을 최소화하여 제품의 품질을 향상시킬 수 있게 된다.As described above, according to the hot air fusion nozzle according to the present invention, the hot air fusion nozzle is formed not only on both sides but also in the center of the injection flow path by spraying hot air to the workpiece in three directions to ensure a stable hot air fusion This makes it possible, thereby minimizing fusion defects and improving the quality of the product.
