On the Dispelling of Protective Equipment of Shrink Wrapper on Packaging Machinery

Shrink wrapper is one of the most advanced packaging methods in the market. It is wrapped with shrink film on the outside of the product or package. After heating, the shrinking film is tightly wrapped around the product or package, fully displaying the appearance of the product, improving the product's saleability, and increasing the appearance. And sense of value.

The heat shrinkable packaging machine can be divided into PE film heat shrinkable packaging machine and PVC/POF film heat shrinkable packaging machine. The FX-PE5040 ordinary PE film shrinking packaging machine belongs to the tunnel in Xiaolan Town Fengxing Packaging Machinery Factory of Zhongshan City. The principle of the heat shrinkable machine FX-PE5040 is that the products packed with the heat shrinkable film are heated by the hot air tunnel of the machine, so that the heat shrinkable film can be tightly wrapped to achieve the effect of shrink packaging. At the same time, both the heating part of the sides and the bottom and the tunnel space must reach 120°C or higher in order to achieve the heat shrinkable packaging effect.

Fengxing Packaging Machinery Factory's Hot Air Circulation PE Shrink Film Packaging Machine

Under normal circumstances, when the heat shrinkable packaging machine is in operation, the operator's palm and other parts are not allowed to come in contact with the operating part of the machine. In particular, the temperature inside the shrinking room is extremely high and it is easy to burn. In view of this safety considerations, the FX-PE5040 ordinary PE film heat shrinkable packaging machine heat pipe and the fan are located inside the heat-insulating furnace in the entrance and exit of the heat-resistant curtain, and in the entrance and exit fabric In the middle of the curtain above the eye-catching position, there is a clear sign of high temperature danger.

1. Inside the heating furnace (inner wall), the side wall of the infrared heating tube is installed with iron mesh insulation (open the high temperature resistant curtain, look straight from the furnace inlet or outlet direction, only see the protection network and do not see the heating tube) ;

2. The blades of the fan are above the depth of the furnace about 40 cm from the exit and entrance, and the blades are installed upwards (not protruding from the surface inside the furnace), pull the high temperature resistant curtain, and import or export from the furnace The direction of head-up viewing, basically do not see the fan.

When the machine is powered on, the heat pipe inside the furnace starts to heat up and can be heated to 150°C or even higher in accordance with the requirements. The fan also operates at the same time to even out the temperature of the furnace. When the machine is shut down, the heating tube is powered off, and the fan continues to run after cooling and cooling.

FX-PE5040 ordinary PE film shrink packaging machine more detailed and in place safety considerations basically no hidden dangers. However, if the operator ignores the safety warning signs posted on the machine and knows that the internal furnace is at high temperature, the handle will be forced through the high-temperature isolation curtain and enter the high-temperature furnace. Even if the infrared tube inside the isolated iron mesh is not touched, it will be internal. The hot air or the high temperature of the furnace wall metal occurs different degrees of scalding! Visible in this accident, it is not necessary to touch the heat pipe inside the insulated iron net installed in the inner wall of the furnace, and any part within the furnace interior may be shone. Injury; if the operator must brave the danger of being blanched to the depths of the hearth to touch the rapidly rotating fan, it is tantamount to knowing that the train will immediately jump on the track! This is very Extremely, any advanced equipment cannot be avoided.

It has been suggested that in order not to reach inside the hearth of a heat shrinkable packaging machine, adding a shroud to the delivery platform at the inlet and outlet ends may be a rough idea, but it may inconvenience practical use. It can be said that some of them have deviated from the basic functions and values ​​of the machine. None of the actual products use this kind of structure (the author refers to similar products from Italy and Germany and no such device is available). If it is hard to say that there are hidden dangers in security, then the home gas stove, who can not see the fire stove? It is mainly the operator must be professional training, strictly abide by the norms of operation.

The working principle and function of the FX-PE5040 common PE film heat shrink packaging machine are given for the protection of the dangerous part of the heat shrink packaging machine and the failure of the sealing cutting and tying mechanism as a failure of the Guangdong Province Technical Supervision Machinery Product Quality Supervision and Inspection Station. A reasonable explanation.
