Description

이액형 점성유체 압출건{Extrude gun for two-part viscous fluid}Extrude gun for two-part viscous fluid

본 발명은 각각 다른 종류의 점성유체로 충진된 두 개의 튜브가 일체로 결합된 이중카트리지를 동시에 압출하는 이액형 점성유체 압출건에 관한 것이다.The present invention relates to a two-part viscous fluid extrusion gun which simultaneously extrudes a double cartridge in which two tubes filled with different types of viscous fluid are integrally combined.

더욱 상세하게는 인력이나 전지를 사용하지 않고 압축공기를 이용하여 권총형으로 형성되는 압출건의 손잡이부 전진스위치를 누름에 따라 본체덮개 내부에 있는 복동식 공압실린더의 푸쉬로드를 수평으로 이동하면서 이중카트리지에 담겨진 다른 두 종류의 점성유체를 동시에 압출시킬 수 있고, 이중카트리지를 교환할 경우 손잡이부의 후진스위치를 누름에 따라 푸쉬로드를 원위치로 복귀시킬 수 있는 이액형 점성유체 압출건에 관한 것이다.More specifically, the dual cartridge is moved horizontally by moving the push rod of the double-acting pneumatic cylinder inside the main body cover by pressing the handle forward switch of the extrusion gun which is formed into a pistol type using compressed air without using manpower or batteries. It relates to a two-component viscous fluid extrusion gun that can simultaneously extrude two different types of viscous fluid contained in it, and return the push rod to its original position by pressing the reverse switch of the handle when double cartridges are exchanged.

종래의 이액형 점성유체 압출건은 일반적인 형상이 권총형으로 형성되며, 압출건의 선단 카트리지 끼움부에 점성유체로 충진된 이중카트리지를 장착하고 압출하고자 하는 경우에는 방아쇠부를 검지로 당겨서, 방아쇠부를 당기는 힘에 의해 2 개의 푸쉬로드를 전방으로 수평이동하면서 이중카트리지에 충진된 두 종류의 점성유체를 동시에 압출하도록 되어 있다. Conventional two-component viscous fluid extrusion gun has a general shape in the form of a pistol, and when a double cartridge filled with a viscous fluid is attached to the tip cartridge insert of the extrusion gun, the trigger part is pulled by the index finger to pull the trigger part. The two push rods are moved horizontally forward to simultaneously extrude two types of viscous fluids filled in the double cartridge.

상기 이중카트리지 내에 충진된 점성유체의 점도가 뻑뻑할 정도로 높은 점성을 지닌 겔(gel) 형태일 경우, 검지 손가락의 힘만으로는 짜내는 데에 매우 많은 힘이 들게 되는 문제가 있고, 힘이 많이 들면 이중카트리지 선단부가 흔들려서 점성유체를 짜내야 할 위치에 정확하게 짜내지 못하게 되는 문제가 있다.If the viscosity of the viscous fluid filled in the double cartridge in the form of a gel (gel) having a high viscosity to be stiff, there is a problem that takes a lot of force to squeeze only by the force of the index finger, if a lot of strength There is a problem in that the tip of the cartridge is shaken, so that it is impossible to squeeze the viscous fluid correctly.

상기의 문제점을 해결하기 위한 종래의 기술로는, 대한민국 등록실용신안 제20-0438381호, '실리콘 건의 손잡이 구조'에서는 검지 손가락의 부하를 적게 하여 부드럽게 작업할 수 있는 손잡이 구조를 제안하고 있고, 대한민국 등록실용신안 제20-0438752호, '에어압력을 이용한 전동 실리콘압출기'에서는 압축공기를 이용하여 대용량의 실리콘을 사용할 경우 작업의 효율성을 높일 수 있는 장점을 기술하고 있다. 상기의 기술은 단일 실리콘 압출건에 대한 고안으로 이액형 이중카트리지를 동시에 압출하는 기술에는 부족함이 있다.As a conventional technique for solving the above problems, the Republic of Korea Utility Model No. 20-0438381, 'The handle structure of the silicone gun' proposes a handle structure that can work smoothly by reducing the load of the index finger, Republic of Korea Registered Utility Model No. 20-0438752, 'Electric Silicon Extruder Using Air Pressure,' describes the advantage of increasing the efficiency of work when using a large amount of silicon using compressed air. The above technique is devised for a single silicon extrusion gun, and the technique for simultaneously extruding a two-component double cartridge is insufficient.

이액형 이중카트리지 압출건에 대한 종래의 기술로서는 대한민국 등록특허 제10-0906825호, '이액형 의료용 점성유체 압출건'에서는 전지를 이용한 구동모터와 베벨기어와 2개의 수평이동바를 포함하는 압출건을 기술하고 있지만, 구동모터와 밧데리를 본체에 내장함으로써 무겁고, 압출건을 제작하기에 어려움이 있으며, 사용할 때마다 재충전해야하는 단점을 가지고 있다. 또한 점도가 높은 점성유체를 압출할 경우에는 높은 부하로 인해 모터의 발열, 폭발 등의 안전사고가 발생할 수도 있다.As a conventional technique for a two-component double cartridge extrusion gun, Republic of Korea Patent No. 10-0906825, 'two-component medical viscous fluid extrusion gun' uses an extrusion gun including a driving motor, a bevel gear, and two horizontal moving bars using a battery. Although described, the drive motor and the battery is built into the main body is heavy, difficult to manufacture the extrusion gun, and has the disadvantage of recharging each time you use. In addition, when extruding a viscous fluid with high viscosity, a high load may cause safety accidents such as heat generation and explosion of the motor.

상기 손잡이부(2) 하부에 하이스피드용 에어 컨넥터와 체결된 공기유입관(1)이 연결된다. The air inlet pipe 1 coupled to the high speed air connector is connected to the lower portion of the handle part 2.

상기 손잡이부(2) 내부에는 공기유입관(1)과 연결된 T-연결관(30) 및 공기튜브(13)을 거쳐 전진스위치(6)와 연결된 전진 솔레노이드밸브(20)와 후진스위치(5)와 연결된 후진 솔레노이드밸브(21)에 연결되고, 상기 전진 솔레노이드밸브(20)와 후진 솔레노이드밸브(21)은 각각은 공기튜브(13)를 거쳐 실린더 전진유입관(12), 실린더 후진유입관(16)을 통해 실린더(11)의 측벽면에 체결된다. The solenoid valve 20 and the reverse switch 5 connected to the forward switch 6 through the T-connecting tube 30 and the air tube 13 connected to the air inlet pipe 1 inside the handle part 2. And a forward solenoid valve 20 and a reverse solenoid valve 21 connected to the reverse solenoid valve 21 and the reverse solenoid valve 21, respectively, through the air tube 13, the cylinder forward inlet pipe 12, and the cylinder backward inlet pipe 16. It is fastened to the side wall surface of the cylinder 11 through).

상기 본체덮개(10)의 개구된 전방에는 각기 다른 점성유체가 채워진 한 쌍의 튜브가 일체로 결합된 이중카트리지(4)의 후방 플랜지부(9)가 끼워져 걸리는 카트리지 끼움부(19)가 설치되어, 이중카트리지(4)를 용이하게 탈부착이 가능하다.In the opened front of the main body cover 10, a cartridge fitting portion 19 is provided in which the rear flange portion 9 of the double cartridge 4 in which a pair of tubes filled with different viscous fluids are integrally fitted is fitted. , Double cartridge (4) can be easily removable.

상기 본체덮개(10) 내부에는 오링(14)을 포함하는 피스톤(15)과 피스톤(15)에 결합된 한 쌍의 푸쉬로드(17)와 피스톤(15)의 운동방향을 안내하는 실린더(11)와 실린더(11)와 기밀을 유지하는 실린더 상부커버(3)과 실린더 하부커버(18)를 포함하는 복동식 공압실린더로 구성되어 있다.The cylinder 11 for guiding the movement direction of the piston 15 including the O-ring 14 and a pair of push rods 17 and the piston 15 coupled to the piston 15 inside the body cover 10.

Prevents dripping down.

이중카트리지(4)를 교체할 경우에는, 상기 압출건의 손잡이부(2) 전방에 있는 후진스위치(5)를 누름에 따라 후진 솔레노이드밸브(21)의 개폐로 압축공기는 공기튜브(13), 실린더 후진유입관(16)을 거쳐 실린더(11)로 공급되면서, 푸쉬로드(17)를 원상태로 복귀시킨 후 이중카트리지(4)를 교환한다.When the double cartridge 4 is replaced, the compressed air is opened by opening and closing the reverse solenoid valve 21 by pressing the reverse switch 5 in front of the handle part 2 of the extruder gun. While the reverse inlet pipe 16 is supplied to the cylinder 11, the push rod 17 is returned to its original state, and then the double cartridge 4 is replaced.
