Shrink packaging machine is one of the more advanced packaging methods in the market. It is wrapped around the product or package by shrink film. After heating, the shrink film is wrapped around the product or package to fully display the appearance of the product, improve the product's marketing performance and increase the appearance. And a sense of value. Hot air circulation type PE heat shrinkable film packaging machine of Fengxing Packaging Machinery Factory Under normal circumstances, when the heat shrink packaging machine is in operation, the operator's palm and other parts are not allowed to come into contact with the running part of the machine, especially the temperature inside the shrinking chamber is extremely high, and it is easy to burn. For this safety consideration, the FX-PE5040 ordinary PE film heat shrink packaging machine heating tube and the fan are located in the heating furnace with high temperature curtains at the entrance and exit, and at the inlet and outlet. The eye-catching position in the middle of the curtain is marked with a noticeable high temperature hazard.
The heat shrink packaging machine can be divided into PE film heat shrink packaging machine and PVC/POF film heat shrink packaging machine according to the film. A FX-PE5040 ordinary PE film heat shrink packaging machine belonging to Zhongshan Xiaolan Town Fengxing Packaging Machinery Factory belongs to the tunnel. The heat shrinking machine, FX-PE5040 adopts the principle that the product wrapped with the heat shrinkable film is heated by the hot air tunnel of the machine to shrink and shrink the heat shrinkable film to achieve the shrink packaging effect. At the same time, it includes the heating parts on both sides and the bottom as well as the tunnel space. The temperature must reach 120 °C or higher to meet the heat shrink packaging effect.
1. Inside the heating furnace (inner wall), the side wall of the infrared heating tube is installed with iron mesh isolation (pull the high temperature resistant curtain, view it from the inlet or outlet of the furnace, and only see the net and not see the heating pipe) ;
2. The fan blades are above the depth of the furnace that is about 40 cm deep from the exit and the inlet, and the fan blades are installed upwards (not protruding on the surface inside the furnace), and the high temperature curtains are opened and imported or exported from the furnace. The direction is normal, and the fan blades are basically invisible.
When the machine is powered on, the heating pipe in the furnace starts to heat up, and can be heated to 150 ° C or higher according to the use requirements, and the fan also operates at the same time to achieve uniform furnace temperature. When the machine is shut down, the heating pipe is cut off, and the fan continues to run after the heat is cooled down.
FX-PE5040 ordinary PE film heat shrink packaging machine has no hidden dangers in the safety considerations. However, if the operator ignores the safety warning signs posted on the machine, knowing that the internal heat of the furnace is dangerous, the handle is forcibly passed through the high-temperature isolation curtain and enters the high-temperature furnace. Even if the infrared tube inside the isolation iron mesh is not touched, it will be internal. The hot air or the high temperature of the furnace wall metal has different degrees of burns! It can be seen that this kind of accident does not necessarily touch the heating pipe installed inside the iron mesh of the inner wall of the furnace. It may be scratched in any part of the inner part of the furnace; if the operator must risk the danger of being scratched Go deep into the depression in the depths of the hearth to touch the fast-rotating fan. It is tantamount to knowing that the train will arrive on the rails immediately! This situation is extremely extreme and any advanced equipment cannot be avoided.
Some people have suggested that in order not to let people reach into the hearth of the heat shrink packaging machine, the shield on the inlet and outlet ends of the conveyor platform may be a good idea, but it brings a lot of inconvenience to the actual use. It can be said that there are some deviations from the basic functions and values ​​of the machine. None of the real products adopt this structure (the author refers to similar products in Italy and Germany, and there is no such device). If it is hard to say that there is a safety hazard, the gas stove of the household, who can't see the flame in the stove? Mainly the operator must be professionally trained and strictly follow the instructions.
According to the Guangdong Provincial Technical Supervision Machinery Product Quality Supervision and Inspection Station, the protection of the dangerous parts of the heat shrink packaging machine and the sealing and bundling mechanism as the disqualification, the working principle and function of the FX-PE5040 ordinary PE film heat shrink packaging machine are given. A reasonable explanation.
