The double-layer auxiliary material belt 300 is unwound from the unwinding assembly 500 for a certain length and then separated into two single-layer auxiliary material belts 300. The auxiliary material belts 300 respectively pass through the opposite sides of the two heating assemblies 200 and are respectively wound on the two winding assemblies 600. When the product is transmitted between the two heating assemblies 200, the lifting cylinder 204 in the heating assembly 200 drives the lifting seat 201 to lift and lower, so that the silicone sheets 203 on the two lifting seats 201 contact the auxiliary material belt 300 and squeeze it to contact the upper and lower outer walls of the product. At the same time, the heating seat 202 in the heating assembly 200 is driven by the lifting cylinder 204 in the heating assembly 200. Electric heating provides the required temperature for heating, so that the purpose of heating the product through the auxiliary material tape 300 can be achieved. Among them, when the auxiliary material tape 300 is located at a local position of the heating component 200 and cannot be used or bubbles or gaps appear during use, it is only necessary to roll up the auxiliary material tape 300 for a certain length through the winding component 600 to collect the waste area on the auxiliary material tape 300 after use, and at the same time move the unused area on the auxiliary material tape 300 to the position of the heating component 200 for use, so that the waste collection and replacement of the auxiliary material tape 300 becomes more convenient and efficient, meeting the use requirements.

[0022] It should be noted that auxiliary material guide seats 205 fixed to the lifting seat 201 are provided at both sides of the heating seat 202, and a pressing cylinder 206 fixed to the lifting seat 201 is provided on the side of the auxiliary material guide seat 205 away from the heating seat 202, and a pressing block 207 is fixedly connected to the telescopic end of the pressing cylinder 206 facing the auxiliary material guide seat 205; a roller frame 208 extending toward the lifting cylinder 204 is fixedly connected to the bottom of the pressing cylinder 206, and a rotatable transmission roller 209 is connected to the inner end of the roller frame 208 away from the pressing cylinder 206;

[0024] Furthermore, an auxiliary transmission mechanism 400 is provided between the frame 100 and the unwinding assembly 500. The auxiliary transmission mechanism 400 is used for positioning and guiding the auxiliary material belt 300.
