Packaging machinery single head heating tube common problems

Packaging equipment before and after feeding, must be based on the heater to press the plastic block packaging products into a bag, the heater is generally used with electric heating tube strip metal material block, equipment work when the two metal material block will quickly close, clamping plastic packaging products raw materials of the moment will be welded and sealed, and then immediately spread out, carry out the next section of sealing, cycle.


At this stage of the packaging film, the temperature is too low or too high will harm the actual effect of the packaging at the same time, so the selection of the heating tube is very critical. Which heating tubes are more suitable for packaging equipment? How to ensure that each batch of the same heating tube can meet the requirements? Which heating tubes should be used for packaging products with high sealing standards? This article gives a simple and detailed introduction.

General single-head heating pipe in the packaging machine what are the problems?

Problem 1 - The outlet connection is very easy to break.

When the automatic packaging machine is sealed, it continuously opens and closes 40-80 times per minute, and the fast type can do more than 100 times per minute. In the whole process of opening and closing, the heating tube does high-frequency repeated movement with the sealing metal material block, and the conductor of the heating tube does "simple pendulum movement", so the outlet of the heating tube is very easy to damage, and most of the damage method is to disconnect.

If the outlet connection is very easy to crack, the internal linear single-head heating tube can be applied, and the wear resistance wire is used. The internal linear single head heating pipe has a detailed explanation on the official website of Lin Zhi, and there is no additional description here.

Problem 2 - Heating pipe wires are very easily damaged.

The same as problem 1, because of the high frequency of continuous movement, friction and impact between the line and the middle of the line, the line and the machine equipment are inevitable, and in the long run, it will lead to problems such as wire damage and core short circuit failure.

A solution for heating pipe wires that are very vulnerable - use metal braided wires or corrugated hoses to maintain wires. For the heating pipe of Linshi, the type of wire, the maintenance structure of wire and its size are all customized according to the customer's use environment.

Problem 3 - The machine and equipment are disorganized.

Many automatic packaging machines are multiple or even more than ten groups of independent packaging modules at the same time, so that there may be a lot of complicated wires. In particular, machines and equipment with narrow space at the outlet of the heating pipe often cause excessive bending of the wire at the outlet of the heating pipe.

A solution to the disarray of machine lines - Select a single head heating tube with a right Angle outlet. For machines and equipment with multiple outlet wires in disarray, or when the outlet of the heating pipe wire must be bent, the right-angle single-head heating pipe is used, so that the wires of the single-head heating pipe can be arranged uniformly in the same direction, which is conducive to improving the overall wiring of the machine and equipment.

Problem 4 - Uneven sealing temperature

The uneven sealing temperature most often occurs in the long sealing machine equipment, because of its long span and fast heat discharge on both sides, resulting in the middle of the temperature is higher than the temperature on both sides of 10~30℃, if the material of the packaging bag is very sensitive to temperature, it is likely to lead to the middle of the melting or lead to no good sealing on both sides.

Solution for uneven sealing temperature - soaking type single head heating tube. This kind of heating tube has the same appearance as the general heating tube, but the output power can be compensated for the ultra-low temperature area on the heating key, so that the overall temperature of the heating tube is the same.
