Generally, the temperature of the preheating zone and the temperature of the heating zone can be adjusted according to the actual thermal shrinkage process and the external environment temperature, and specifically, the temperature adjustment can be realized by adjusting the energizing current or adjusting the spacing between corresponding components. When the conveying chain 50 rotates in the forward direction in a cyclic and reciprocating manner, the anchor bolt 200 moves forward in a rolling state, when the anchor bolt enters the preheating zone, the two heating parts preheat the heat shrinkage tube, and after the anchor bolt 200 continues to roll backwards and enter the heat shrinkage heating zone, the heat shrinkage processing is completed. In practice, to ensure good heat shrinkage heating, the speed of the conveyor chain 50 needs to be controlled to match the heating temperature.
