The specific working procedure is as follows:
when the polyester yarns are stretched, the polyester yarns enter the main body 1 from an inlet at the left side of the main body 1, sequentially pass through the guide roller 4, the heating roller body 31, the heating plate 2, the heating roller body 31, the guide roller 4, the stretching roller 5 and the guide roller 4, and leave the stretching equipment from an outlet at the right side of the main body 1;
meanwhile, as the heating roller bodies 31 are symmetrically arranged at the left side and the right side of the heating plate 2, when the polyester yarns pass through the heating roller bodies 31, the sponge layers 32 positioned on the heating roller bodies 31 contact the polyester yarns and limit the polyester yarns to a certain extent;
meanwhile, as the sponge layer 32 is loose and porous, the hot air sent into the heating roller body 31 by the hot air blower 6 and discharged from the micropores can be influenced by the sponge layer 32 to be smooth and uniform, and then the hot air passing through the sponge layer 32 contacts with polyester yarns to preheat the polyester yarns to a certain extent;
meanwhile, since the heating roller bodies 31 are symmetrically arranged at the left side and the right side of the heating plate 2, after the hot air generated by the hot air blower 6 is discharged from the sponge layer 32 on the heating roller bodies 31, the hot air generated by the hot air blower 6 is relatively concentrated at the two ends of the heating plate 2, so that a blocking effect is generated at the two ends of the heating plate 2;
because a gap exists between the linear speed of rotation of the heating roller body 31 and the speed of movement of the polyester yarns, when the polyester yarns pass through the heating roller body 31, certain relative movement exists between the polyester yarns and the heating roller body 31;
because the polyester yarns are positioned in the channel formed by the protrusions 322 and the grooves 321 on the sponge layer 32, and the fluff brush 323 which can be in contact with the polyester yarns is arranged on the protrusions 322, the polyester yarns can be swept by the fluff brush 323 when running in stretching equipment, the sponge layer 32 on the heating roller 31 positioned on the left side of the heating plate 2 cleans impurities and dust remained in the production process of the polyester yarns, and the sponge layer 32 on the heating roller 31 positioned on the right side of the heating plate 2 cleans impurities and dust loosened in the heating process of the polyester yarns;
the hot air fed into the heating roller body 31 by the hot air blower 6 is prevented from being discharged from the two ends of the sponge layer 32 by the sealing films 33 arranged at the two ends of the sponge layer 32;
because the linear speeds of the heating roller bodies 31 at the two sides of the heating plate 2 are different from those of the polyester yarns, the heating roller bodies 31 at the left side of the heating plate 2 rotate clockwise relative to the polyester yarns, and the heating roller bodies 31 at the right side of the heating plate 2 move anticlockwise relative to the polyester yarns, so that impurities, dust and the like on the contacted polyester yarns are cleaned away from the heating plate 2 by the velvet brushes 323 in the rotating process of the heating roller bodies 31;

meanwhile, after the hot air generated by the hot air blower 6 enters the heating plate 2, the hot air in the heating plate 2 is transmitted into the heating roller body 31 through the communicating pipe 22, so that the hot air is further utilized, and meanwhile, the hot air discharged from the heating plate 2 enters the heating roller body 31 and is discharged from the sponge layer 32, and the temperature of the hot air is close to the temperature in the heating plate 2;
through the limiting rings 41 arranged on the guide roller 4, the polyester yarns are always positioned between the two limiting rings 41 in the movement process, so that the relative position of the polyester yarns in stretching equipment is ensured to be stable, and meanwhile, when a plurality of polyester yarns are stretched at the same time, the limiting rings 41 are utilized to separate the polyester yarns;
by covering a silica gel layer on the surfaces of the guide roller 4 and the limiting ring 41, friction force between the polyester yarns and the guide roller 4 and friction force between the polyester yarns and the stretching roller 5 are increased, so that the stretching roller 5 has good stretching effect on the polyester yarns by utilizing differential speed, and meanwhile, when the surface of the limiting ring 41 is smooth, the polyester yarns can slide from the limiting ring 41 and pass over the limiting ring 41 through the silica gel layer arranged on the limiting ring 41;
through adding conductive filler in the silica gel layer, the silica gel layer has certain conductive performance, so that static electricity generated by friction is released after contacting the silica gel layer in the motion process of the polyester yarns.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
