Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency forming guide roller for a papermaking machine, including a shaft body 1 and a roller body 2. A cavity 101 is opened in the middle of the shaft body 1. A connecting rod 11 is fixedly connected between the two inner side walls of the cavity 101. A plurality of damping blocks 12 are fixedly connected to the outer walls of the connecting rod 11. An arc plate 13 is fixedly connected to the top of the plurality of damping blocks 12. A spring 14 is fixedly connected between the plurality of arc plates 13 and the connecting rod 11. An aerogel heat insulation groove 201 is opened inside the roller body 2 near the outer end of the cavity 101.
[0018] Furthermore, the shaft wall of the shaft body 1 is fixedly connected to both sides of the roller body 2 via couplings 15, and the shaft body 1 is installed on the paper machine via the couplings 15.
[0019] Furthermore, the diameters of several arc-shaped plates 13 are adapted to the diameter of the chamber 101, and the several arc-shaped plates 13 abut against the inner wall of the chamber 101.
[0020] Furthermore, an inlet tube 21 is embedded on one side of the inner wall of the aerogel insulation tank 201, through which aerogel is injected into the aerogel insulation tank 201.
[0021] Furthermore, the aerogel insulation groove 201 is located near the outer end of the shaft 1, and the aerogel stored in the aerogel insulation groove 201 can absorb the energy of the impact.
[0022] Specifically, when using this utility model, when the guide roller needs to be installed on the equipment, the aerogel is first injected into the aerogel insulation tank 201 through the glue inlet pipe 21, and then the shaft 1 is installed on the paper machine through the coupling 15. When the guide roller rotates, the aerogel stored in the aerogel insulation tank 201 can absorb the impact energy. When the impact energy is transmitted to the chamber 101, it can be buffered by several arc plates 13 and damping blocks 12. Furthermore, the use of several springs 14 can improve the buffering effect and prevent the shaft 1 from being damaged by a large energy impact.
