Description

Technical Field

[0001] The utility model relates to the technical field of extruder embossing, in particular to heat exchange extruder embossing equipment. Background Art

[0002] In the process of plastic extrusion, it is a common requirement to emboss the extruded product in order to improve the surface aesthetics and functionality of the product. However, there are some obvious problems with the current extruder embossing equipment.

[0003] On the one hand, the embossing effect is not satisfactory and the embossing process is not stable enough; on the other hand, each extruder needs to be equipped with a flower roller and a rubber roller, and the temperature of their inlet and outlet can only be measured by a temperature gun, which has many disadvantages. First, using a temperature gun to measure is very cumbersome, time-consuming and labor-intensive; second, the temperature gun can only measure the temperature of the water pipe surface, and cannot accurately obtain the actual water temperature of the inlet and outlet, which makes it impossible to obtain accurate temperature data, and accurate temperature control is crucial for the normal operation of the extruder. Therefore, it is urgent to find a more convenient and accurate temperature monitoring method. Utility Model Content
