It relates to a non-electric sand blasting machine that operates only with a pressurized air, characterized in that it comprises a; sanding gun 160 formed to be injected through the sand and the high pressure air through the sanding nozzle (150).

본 발명은 종래 샌드 브라스트기가 메타링밸브, 공압밸브 등을 전기식 솔레노이드밸브를 사용하고 제어부를 설치하여 사용함으로써 전기가 없는 곳에서 연마작업이 불가능하였으며, 또한 구성이 복잡해지고 고장이 자주 발생하는 문제점이 있었으며 이는 작업생산성을 저하시키는 요인이 되고 있었다.The present invention is a conventional sand blasting machine using an electric solenoid valve, such as a metal ring valve, a pneumatic valve and installed a control unit, it is impossible to grind in the place where there is no electricity, and also complicated configuration and frequent failures This was a factor in lowering work productivity.

본 발명은 샌딩건의 트리거를 고압에어의 밸브역할이 되도록 형성하여 트리거를 누르면 고압에어가 흘러 메타링밸브와 공압밸브의 폐쇄부를 개방하도록 형성함으로써 샌딩노즐을 통하여 에어와 샌드가 분사되도록 형성한 것이다.According to the present invention, the trigger of the sanding gun is formed to serve as a valve of the high pressure air, and when the trigger is pressed, the high pressure air flows to open the closed portions of the meta ring valve and the pneumatic valve, thereby forming air and sand through the sanding nozzle.

본 발명은 에어의 힘을 사용하여 개폐되는 시판 메타링밸브와 공압밸브를 샌딩건의 트리거와 연동하여 작동하도록 구성한 것으로, 전기를 사용하지 않아도 되기 때문에 전기시설이 없는 시골에서도 사용할 수 있으며, 이동식 샌드 브라스트기로 만들어 어느 곳이든 이동시켜 연마 작업할 수 있는 것이다.The present invention is configured to operate in conjunction with the trigger of the sanding gun commercially available meta-ring valve and pneumatic valve that is opened and closed by using the force of the air, can be used even in the countryside without electric facilities, because it does not require electricity, removable sand brass You can make it with sand to move it anywhere and polish it.

가압에어를 1차 저장한 보조탱크로부터 유입되는 고압에어는 공압밸브와 메타링밸브를 통과하면서 메타링밸브에서 샌드와 함께 혼합되어 샌딩노즐로 분사되는 것이다.The high pressure air flowing from the auxiliary tank storing the pressurized air as primary is mixed with sand from the meta ring valve and injected into the sanding nozzle while passing through the pneumatic valve and the meta ring valve.

에어에 의해 작동하는 메타일밸브는 실린드식으로 작동하여 개폐하는 것이며, 공압밸브 또한 에어에 의해 개폐부가 개폐되도록 형성된 것이다.The metail valve operated by air is a cylinder type operation to open and close, and the pneumatic valve is also formed to open and close the opening and closing by air.

유입관으로 들어오는 에어는 에어건의 트리거를 누르면 메타링밸브와 공압밸브를 오픈되도록 작동하게 되며, 이 때 보조탱크로부터 고압에어가 공압밸브를 통과하여 메타링밸브를 통과하면서 샌드를 혼합하여 샌딩노즐로 이송하시켜 분사하도록 구성한 것이다.The air entering the inlet pipe is operated to open the metering valve and pneumatic valve by pressing the trigger of the air gun. At this time, the high pressure air from the auxiliary tank passes through the pneumatic valve and passes through the metering valve to mix sand with sanding nozzle. It is configured to be transported and sprayed.

이러한 본 발명은 연마를 위해 에어건의 트리거를 당기면 바로 샌딩노즐로 분사되도록 구성되어 간단하면서 작업을 위해 편리하게 구성된 것이다.The present invention is configured to be sprayed into the sanding nozzle as soon as pulling the trigger of the air gun for polishing is simple and conveniently configured for work.

이 외에도 본 발명은 또한 트리기의 동작을 자동장치와 연결하면 제어부 설정에 의해 자동연마 작업할 수 있는 것이기도 하다.In addition to this, the present invention is also capable of automatic polishing operation by setting the control unit when the operation of the trigger is connected to the automatic device.

본 발명의 샌드브라스트기는 샌딩건의 트리거(164)를 누르면 유입관(161)로 유입되는 고압에어가 트리거를 통과하여 유출관(162)를 통하여 흘러 실린더(145)를 작동시켜 메타링밸브를 오픈상태로 함으로 동시에, 유출관(162)로 흐른 고압공기가 공압밸브에 도달하여 공압밸브(140)를 오픈상태를 형성함으로써 고압에어가 공압밸브(140)에서 메타링밸크를 통과하여 샌딩노즐(150)로 분사되도록 형성된 트리거와 연동되도록 구현한 것으로, 전기를 사용하지 않기 때문에 전기가없는 곳에서도 샌딩작업을 할 있는 효과가 있으며, 또한 종래 전기식 솔레노이드밸브 사용의 경우 구성이 복잡하고 고장 등의 문제점이 있었던 것을 본 발명은 에어만으로 작동하는 간단한 구조의 것으로 고장이 거의 없는 등의 효과가 있다.When the sand blasting machine of the present invention presses the trigger 164 of the sanding gun, the high pressure air flowing into the inlet pipe 161 flows through the trigger and flows through the outlet pipe 162 to operate the cylinder 145 to open the metaring valve. At the same time, the high pressure air flowing through the outlet pipe 162 reaches the pneumatic valve and forms the open pneumatic valve 140, so that the high pressure air passes through the meta ring valve in the pneumatic valve 140 and the sanding nozzle 150 Implemented to interlock with the trigger formed to be sprayed by), because it does not use electricity, there is an effect that can be sanded even in the absence of electricity, and in the case of using a conventional electric solenoid valve, the configuration is complicated and problems such as failure The present invention has a simple structure that operates only with air, and there is almost no failure.

도 1: 본 발명의 구성을 도시한 것이다.1 shows a configuration of the present invention.

도 1에서 보는 바와 같이, 본 발명은 공급호퍼(115)로부터 샌드(111)가 공급되고 고압에어가 보조탱크(120)로부터 공급되면 고압에어에 의해 샌드는 아래로 방출되도록 메인탱트가 형성된 것이다.As shown in FIG. 1, when the sand 111 is supplied from the supply hopper 115 and the high pressure air is supplied from the auxiliary tank 120, the main tank is formed such that the sand is discharged downward by the high pressure air.

트리거(164)를 누르면 이와 연동하여 메타링밸브(130)가 오픈되어 보조탱크(120)-유입관(163)-공압밸브(140)-메타링밸크로 들어오는 고압에어에 의해 샌드와 고압에어가 통과하여 센딩노즐(150)로 분사되어 연마작업하도록 형성된 것이다.When the trigger 164 is pressed, the meta-ring valve 130 is opened in conjunction with this, and sand and the high-pressure air pass through the high-pressure air coming into the auxiliary tank 120-the inlet pipe 163-the pneumatic valve 140-the metal ring. By spraying to the sending nozzle 150 is formed to be polished.

메타링밸브(130)의 개폐동작은 실린더(145)의 작동에 의해 이루어지며, 고압에어가 보조탱크(120)-유입관(161)-샌딩건의 트리거(164)-유출관(162)-실린더(145)로 트리거 누름동작에 의해 실린더를 작동시켜 오픈되도록 형성된 것이며, 트리거를 놓으면 메타링밸브가 차단 상태가 되어 분사가 중단된다.The opening and closing operation of the meta ring valve 130 is performed by the operation of the cylinder 145, and the high pressure air is supplied to the auxiliary tank 120-the inlet pipe 161-the sanding gun trigger 164-the outlet pipe 162-the cylinder. 145 is formed to operate by opening the cylinder by the trigger pressing operation, and when the trigger is released, the meta-ring valve is shut off and the injection is stopped.

본 발명은 샌딩건 트리거(164)와 연동하여 트리거(164)를 누르면 유입관(161)로 유입되는 고압에어는 트리거를 통과하여 실린더(145)를 작동시켜 메타일밸브를 오픈상태로 하고, 동시에 공압밸브(140)를 오픈상태로 형성하여 고압에어가 메타링밸크를 통과하여 샌딩노즐(150)로 분사되도록 형성된 것이다.According to the present invention, when the trigger 164 is pressed in conjunction with the sanding gun trigger 164, the high pressure air flowing into the inlet pipe 161 passes through the trigger to operate the cylinder 145 to open the meta valve. By forming the pneumatic valve 140 in an open state, the high pressure air is formed to be injected into the sanding nozzle 150 through the meta ring.

이와 같이 본 발명은 종래 전기식 솔레노이드밸브가 아니라 고압에어만을 사용하여 트리거 동작에 따라 밸브를 개폐하면서 샌딩작업할 수 있도록 형성된 것으로 구조가 간편할 뿐 아니라 이동식으로 만들어 어디든 이동시켜 샌딩 연마작업이 가능하도록 구현한 것이다.As described above, the present invention is formed so that the sanding operation may be performed while opening and closing the valve according to the triggering operation using only high pressure air instead of the conventional electric solenoid valve. It is.

본 발명의 구성은 상기 실시예에 한정되는 것이 아니며, 통상의 기술범주 내에서 실시할 수 있는 다양한 실시예를 포함하는 것이다.The configuration of the present invention is not limited to the above embodiments, and includes various embodiments that can be implemented within a general technical category.
