Description

진공포장기의 실링바 냉각장치 {COOLING SYSTEM FOR SEALING BAR OF VACUUM PACKING MACHINE} Sealing Bar Cooler of Vacuum Packer {COOLING SYSTEM FOR SEALING BAR OF VACUUM PACKING MACHINE}

본 발명은 진공포장기의 실링바 냉각장치에 관한 것으로, 특히 노즐식 진공포장기에서 히터가 배치되는 하부의 실링바가 과열되는 것을 방지할 수 있도록 한 진공포장기의 실링바 냉각장치에 관한 것이다.The present invention relates to a sealing bar cooling apparatus of a vacuum packaging machine, and more particularly, to a sealing bar cooling apparatus of a vacuum packaging machine that can prevent overheating of a lower sealing bar in which a heater is disposed in a nozzle type vacuum packaging machine.

통상적으로 필름포장물의 내부를 진공처리하여 내용물을 진공포장하기 위한 진공포장기는 히터가 상면에 배치되는 고정형의 하부실링바와 이에 대응하여 하부실링바에 대해 승강하는 상부실링바로 구성되어 필름포장물의 구부를 열접착으로 밀봉할 수 있도록 하며 하부 실링바와 상부실링바 사이에는 필름포장물이 밀봉되기전에 필름포장물의 내부의 공기를 빼내는 흡입노즐이 전후 또는 좌우로 이동할 수 있도록 배치된다. 그리고 이러한 흡입노즐은 에어필터를 통하여 진공펌프의 흡기측에 연결된다. 이러한 진공포장기에 있어서는 다른 접착포장기기의 경우와 마찬가지로 특히 히터가 배치되는 하부실링바의 과열을 방지하는 것이 중요하다. 히터가 배치된 실링바는 히터의 지속적인 작동으로 잔열이 누적되어 과열상태가 됨으로서 열접착의 불량상태가 유발될 수 있다. 일부의 경우에 있어서는 이러환 실링바의 과열 을 방지하기 위하여 히터의 동작시간중에 열접착을 위한 히터의 온도가 큰 변화없이 일정하게 유지되어 양호한 열접착이 이루어질 수 있도록 하는 온도제어방식을 이용하는 것이 알려진 바 있다. 그럼에도 불구하고 실링바에 잔열이 누적되는 것을 효과적으로 방지하기 위한 수단의 제공이 요구된다.Typically, a vacuum packaging machine for vacuum-packing the contents by vacuuming the inside of the film package is composed of a fixed lower sealing bar in which the heater is disposed on the upper surface and an upper sealing bar corresponding to the lower sealing bar to open the bend of the film package. The sealing nozzle is adhesively sealed and a suction nozzle for extracting air from the inside of the film package is disposed between the lower sealing bar and the upper sealing bar so as to move back and forth or left and right. The suction nozzle is connected to the intake side of the vacuum pump through the air filter. In the vacuum packaging machine, as in the case of other adhesive packaging equipment, it is particularly important to prevent overheating of the lower sealing bar in which the heater is disposed. The sealing bar in which the heater is disposed may be in an overheated state in which residual heat accumulates due to continuous operation of the heater, thereby causing a poor state of thermal bonding. In some cases, in order to prevent overheating of the ring sealing bar, it is known to use a temperature control method in which the temperature of the heater for thermal bonding is kept constant without significant change during the operating time of the heater so that good thermal bonding can be achieved. There is a bar. Nevertheless, it is required to provide a means for effectively preventing the accumulation of residual heat in the sealing bar.

본 발명에 있어서는 종래의 이와 같은 점을 감안하여 창안한 것으로, 노즐식 진공포장기에서 필름포장물의 내부에 들어 있는 공기를 빼내기 위하여 사용되는 진공회로의 공기흐름을 이용하여 히터가 배치되는 하부의 실링바를 냉각시킬 수 있도록 함으로서 실링바가 과열되는 것을 방지할 수 있도록 한 진공포장기의 실링바 냉각장치를 제공하는데 그 목적이 있다.In the present invention, the present invention was made in view of such a conventional situation, and a lower sealing bar in which a heater is disposed using an air flow of a vacuum circuit used for extracting air contained in a film package from a nozzle type vacuum packaging machine is used.
