Description
본 고안은 합성수지 사출성형기의 노즐 주위에서 노즐을 가열 시켜주는 밴드 히터와 같은 각종 산업용 전기히터의 애자 조립체에 관한 것이다.The present invention relates to an insulator assembly of various industrial electric heaters, such as a band heater, which heats a nozzle around a nozzle of a plastic injection molding machine.
종래에 대한민국 실용신안 공고번호 제 91-1364 호로 알려진바 있는 세라믹 애자는 도 4 ∼ 도 6에 도시된 바와 같이 세라믹으로 된 동체(30)의 한쪽에는 호형요입부(31)가 형성되어 있고, 다른 한쪽에는 상기 호형요입부(31)와 대응하는 호형돌출부(32)가 형성되어 있으며, 동체(30)의 길이방향 쪽에는 상기 호형요입부(31)와 호형돌출부(32)를 관통하는 여러개의 구멍(33)이 일정한 간격으로 형성되어 있어서 여러개의 동체(30)를 맞대어서 판상 또는 원통형상으로 배열하고, 연통하는 구멍(33)속에 니크롬선과 같은 전열선(34)을 배선할 수 있도록 된 것이다.Ceramic insulators, which are conventionally known as Korean Utility Model Publication No. 91-1364, have arc-shaped indentations 31 formed on one side of the body 30 made of ceramic, as shown in FIGS. An arc-shaped protrusion 32 corresponding to the arc-shaped recessed portion 31 is formed at one side, and a plurality of holes penetrating the arc-shaped recessed portion 31 and the arc-shaped protrusion 32 are formed at the longitudinal direction of the body 30. (33) are formed at regular intervals so that a plurality of fuselage (30) to face each other arranged in a plate or cylindrical shape, it is possible to wire a heating wire 34 such as nichrome wire in the communication hole (33).
이와 같은 종래의 세라믹 애자는 호형요입부(31)와 호형돌출부(32)의 위, 아래쪽에 각각 턱(35), (35')이 형성된 것이었기 때문에 동체(30)들을 도 3에 도시된 바와 같이 판상으로 맞대어서 배열해 주었을 때에는 동체(30)들의 접촉상태가 비교적 양호하나 도 5와 도 6에 도시된 바와 같이 밴드 히터용으로 사용하기 위해서 원통형상으로 동체(30)들을 배열시켜 주었을 때에는 유연성이 부족하여서 동체(30)들을 진원에 가깝도록 배열시켜 줄 수 없었고, 특히 도 5에 잘 도시된 바와 같이 인접하는 한 동체(30)와 다른 동체(30') 사이에 틈새(36)가 존재하게 되어서 전열선(34)의 배선을 원활하게 할 수 없었으며, 틈새(36)로 말미암아서 열효율이 낮아지게 되었었고, 가열대상 실린더를 균일한 온도로 가열시켜주는데 지장을 초래하는 등의 문제점이 있었다.Since the conventional ceramic insulators are formed in the upper and lower portions of the arc indentation part 31 and the arc protrusion part 32, respectively, the jaws 35 and 35 'are respectively shown in FIG. As shown in Figs. 5 and 6, the contact state of the fuselage 30 is relatively good, but the flexibility of the fuselage 30 is arranged in a cylindrical shape for use for the band heater as shown in Figs. Due to this lack, it was not possible to arrange the fuselage 30 close to the epicenter, and in particular, as shown in FIG. 5, there was a gap 36 between one adjacent fuselage 30 and the other fuselage 30 '. Therefore, the wiring of the heating wire 34 could not be smoothed, the thermal efficiency was lowered due to the gap 36, and there was a problem such as causing trouble in heating the heating target cylinder to a uniform temperature.
본 고안은 이와 같은 종래기술의 제반문제점을 해결한 것인바, 본 고안은 단위 애자들을 연결시켜 주었을 때에 유연성과 밀착성이 우수하여서 전열선을 쉽게 배선 할 수 있고, 열효율이 우수하며 가열대상물을 균일한 온도로 가열시켜 줄 수 있는 산업용 전기히터의 애자 조립체를 제공하는데 기술적 과제를 둔 것이다.The present invention solves all the problems of the prior art. The present invention has excellent flexibility and adhesion when unit insulators are connected, so that the heating wire can be easily wired, the thermal efficiency is excellent, and the heating object has a uniform temperature. The technical problem is to provide an insulator assembly of an industrial electric heater that can be heated by.

본 고안은 도 1에 예시한 바와 같이 양쪽에 호형돌출부(10), (10')가 형성되어 있고, 호형돌출부(10)와 호형돌출부(10')를 관통하는 통상의 구멍(11)을 가진 제 1 애자(12)와, 양쪽에 상기 호형돌출부(10), (10')와 대응하는 호형요입부(13), (13')가 형성되어 있고, 호형요입부(13)와 호형요입부(13')를 관통하는 통상의 구멍(11)을 가진 제 2 애자(14)로 이루어진 애자 조립체이다.In the present invention, as illustrated in FIG. 1, arc protrusions 10 and 10 ′ are formed at both sides, and each has a normal hole 11 penetrating through the arc protrusions 10 and the arc protrusions 10 ′. The first insulator 12 and the arc indents 13 and 13 'corresponding to the arc protrusions 10 and 10' are formed on both sides thereof, and the arc indents 13 and the arc indents are formed. An insulator assembly consisting of a second insulator 14 having a conventional hole 11 penetrating 13 '.
이와 같이 구성된 본 고안은 도 1 ∼ 도 3에 예시한 바와 같이 제 1 애자(12)와 제 2 애자(14)들을 교호로 연결시켜서 판상으로 배열하거나 원통형상으로 배열하여서 사용하는 것인바, 도 3에 잘 표현된 바와 같이 제 1 애자(12)와 제 2 애자(14)가 기울기를 가지면서 연결되더라도 제 1 애자(12)의 호형돌출부(10), (10')와 제 2 애자(14)의 호형요입부(13), (13')는 완전히 밀착된체로 접촉면이 이동될 수 있어서 조립시에 유연성을 갖는다.The present invention configured as described above is to use the first insulator 12 and the second insulator 14 alternately connected to the plate or arranged in a cylindrical shape as shown in Figs. As well expressed in Fig. 1, the arc-shaped protrusions 10, 10 'and the second insulator 14 of the first insulator 12 are connected even though the first insulator 12 and the second insulator 14 are inclined. The arc recesses 13 and 13 'of the arc indents 13 and 13' are completely in close contact with each other so that the contact surface can be moved to have flexibility during assembly.
따라서 본 고안에 의한 애자 조립체는 니크롬선과 같은 전열선(15)을 구멍(11) 속에 끼워 넣을 때 전열선(15)이 걸려질 우려가 없어서 전열선(15)의 배선을 손쉽게 할 수 있도록 해주고, 열손실을 방지해주며, 애자 조립체 전체가 균일하게 가열된다.Therefore, the insulator assembly according to the present invention does not have a risk of catching the heating wire 15 when the heating wire 15, such as nichrome wire, is inserted into the hole 11, so that the wiring of the heating wire 15 can be easily performed, and the heat loss is reduced. The entire insulator assembly is heated evenly.
본 고안에 의한 애자 조립체는 조립시에 유연성과 밀착성이 우수하여서 전열선(15)을 손쉽게 배선할 수 있고, 열효율이 우수하여서 에너지를 절약할 수 있으며, 온도 편차에 물성이 민감하게 변하는 합성수지가 통과하는 사출성형기의 노즐 주위를 균일한 온도로 가열시켜 줄 수 있어서 품질이 균일한 고품위의 사출성형물을 얻을 수 있는 등의 장점이 있다.The insulator assembly according to the present invention has excellent flexibility and adhesion at the time of assembly, so that the heating wire 15 can be easily wired, the thermal efficiency is excellent, energy can be saved, and the synthetic resin whose physical properties are sensitive to temperature variation passes. It is possible to heat the nozzle of the injection molding machine at a uniform temperature, and thus there is an advantage of obtaining a high quality injection molding having a uniform quality.
