How to adjust the temperature of the heat shrink film wrapping machine?

The heat shrink wrapping machine is one of the commonly used equipment in the modern packaging industry. It heat shrinks the product so that the packaging material is close to the surface of the product to protect the product, improve the product appearance and extend the shelf life. In the use of the heat shrink wrapping machine, the adjustment of temperature is a very critical link. This article will introduce in detail how to adjust the temperature of the heat shrink wrapping machine to ensure the quality and efficiency of packaging.

1. Understand the temperature control principle of the heat shrink wrapping machine

The heat shrink wrapping machine usually uses infrared radiation to heat the packaging material and controls the temperature by adjusting the power of the infrared radiator. Adjusting the temperature is actually adjusting the power output of the infrared radiator.

2. Steps for adjusting the temperature of the heat shrink wrapping machine

Before adjusting the temperature, first let the heat shrink wrapping machine preheat for a period of time to ensure that the temperature inside the machine is stable. The length of the preheating time depends on the specific model of the machine and the use environment. It is generally recommended to be about 10-15 minutes. Then set an initial temperature according to the type and thickness of the packaging material.

At the initial temperature, perform heat shrinking treatment for a period of time and observe the shrinking effect of the packaging material. According to the observation results, gradually adjust the temperature. If the temperature is too low, you can increase the temperature appropriately; if the temperature is too high, you need to lower the temperature. The temperature range of each adjustment should not be too large, and it is recommended to control it between 5-10℃.

3. Precautions

During the temperature adjustment process, pay close attention to the shrinkage of the packaging material to avoid excessive or insufficient conditions. The temperature adjustment should be carried out step by step to avoid excessive adjustment at one time, which may cause damage to the machine or deterioration of packaging quality. Packaging materials of different types and thicknesses require different temperature settings, so in actual operation, they should be adjusted according to the specific situation. Clean the heating elements and reflective plates of the heat shrink wrapping machine regularly to ensure heat transfer efficiency and service life.

4. Summary

The temperature adjustment of the heat shrink wrapping machine is a key link to ensure packaging quality and efficiency. By understanding the temperature control principle, following the adjustment steps and precautions, the temperature adjustment of the heat shrink wrapping machine can be easily completed. In actual operation, flexible adjustments should be made according to the specific situation to achieve a popular packaging effect.
