Detailed Description

As shown in fig. 1-2, the present invention comprises: the heating roller comprises a pair of heating roller bodies 1, a reversing slip ring 2, a heating rod 3, a thermocouple 4 and a protection switch 5 which are arranged in an up-down tangent mode;

In use, the film with the thermal sensitive adhesive is compounded on the RFID antenna (Inlay) with the chip, so that the purpose of protecting the chip is achieved.

In this embodiment, it is preferable that a deep hole in which the heating rod 3 and the thermocouple 4 are provided is provided in the axial direction of the end surface of the heating roller body 1.

With the above structure, the heating rod 3 and the thermocouple 4 are inserted into the deep holes, and the mounting positions are provided for the heating rod 3 and the thermocouple 4.

In this embodiment, it is preferable that a plurality of heating rods 3 are provided, and each of the heating rods 3 is provided at equal intervals.

In the present embodiment, six heating rods 3 are preferably provided.

In practice, six heating rods 3 are generally used, but the number of the heating rods is not limited to six, and the heating rods 3 are inserted into the heating roller body 1, so that the heating rods 3 which are evenly distributed heat to generate heat, and the purpose of conducting the heat to the roller surface of the heating roller body 1 is achieved.

In the present embodiment, a thermocouple 4 is preferably disposed between two adjacent heating rods 3 to form a heating zone.

In the present embodiment, preferably, three thermocouples 4 are provided.

In practical use, the number of the thermocouples 4 is half of the number of the heating rods 3, and the heating rods 3 are arranged on two sides of each thermocouple 4 to form independent heating areas.

In this embodiment, it is preferable that the heating roller body 1 located above is made of a metal base, the outer surface of the heating roller body 1 is covered with a rubber pad 6, and the heating roller body 1 located below is made of a metal base.

Set up above-mentioned structure, owing to be located the warming mill body 1 contact chip of top, play the effect of protection RFID chip behind the rubber coating.

When the heating rod is used, the formed 3 heating areas are independently controlled to form 3 temperature areas, when the heating rod is used for heating, the temperature of the corresponding temperature area of the roller surface rises until the temperature reaches a set temperature, the thermocouple feeds back a signal to the PLC control system, and the system stops heating; when the temperature is lower than the set temperature of the system, the thermocouple signals the PLC system again to start heating, so that the temperature is in dynamic balance.

When the system error causes overheating, the protection switch intervenes to cut off the heating current, thereby protecting the operator and the equipment.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
