Abstract
본 발명은 전기 비닐 접착기의 구성회로에 관한 것으로서 자체 노이즈(NOISE)가 외부로 방출되는 것을 방지하는 노이즈 필트회로(1)와 노이즈 필터회로(1)의 교류전원이 트랜스(T2)를 거쳐 브리지 다이오드(D2)를 통해 직류전압으로 변환한 다음 정전압 IC(201)로 인가되어 안정된 B 전원을 공급하게 하는 전원회로(2)와 전원회로(2)의 출력에서 펄스의 출력부를 시상수회로(3)와 펄스폭변조회로(4)를 거쳐 직렬로 연결된 두개의 전계효과 트랜지스터(FET1)(FET2)에 각각 인가하여 교대로 강압트랜스(T4)에 전원을 공급하고 강압트랜스(T4)의 2차측에 비닐접착 히터(5)를 연결하며 전계효과 트랜지스터(FET1)(FET2)의 소오스(S)에 저항(R13)을 연결하여 과전류 제한회로(6)에 의해 펄스폭변조회로(4)의 전원을 차단할 수 있게 한 것으로 펄스폭변조회로(4)를 통해 출력주파수를 20KHz∼50KHz 사이의 고주파수의 전원을 강압 트랜스(T4)에 공급하므로서 회로의 안전성을 보장받을 수 있으면서도 보다 양질의 회로를 제공할 수 있고 강압트랜스(T4)의 소형화 및 경량화로 비닐 접착기를 소형으로 구성하여 사용할 수 있게 되는 비닐접착기의 구성회로가 되는 것이다.The present invention relates to a constituent circuit of an electro-vinyl adhesive machine, wherein an AC power supply of a noise filter circuit (1) and a noise filter circuit (1) that prevents noise from being emitted to the outside is bridged through a transformer (T 2 ). The output of the pulse at the output of the power supply circuit 2 and the power supply circuit 2 which is converted into a direct current voltage through the diode D 2 and then applied to the constant voltage IC 201 to supply a stable B power supply. ) and two field effect transistors (FET 1) (FET 2), respectively applied to shift step-down transformer (T 4) to supply the step-down transformer the power is on (T 4) connected in series via a pulse width modulation circuit (4) The pulse width modulation circuit by the overcurrent limiting circuit (6) by connecting the vinyl adhesive heater (5) to the secondary side of the circuit and connecting the resistor (R 13 ) to the source (S) of the field effect transistor (FET 1 ) (FET 2 ). It is possible to cut off the power of (4). The output frequency may be assured of a high frequency circuit of the safety hameuroseo supplied to the transformer (T 4) of the step-down power between 20KHz~50KHz yet can provide a better quality of the circuit and a vinyl downsizing and weight reduction of step-down transformer (T 4) It becomes a constituent circuit of the vinyl adhesive that can be used to configure the compactor in a small size.
