DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4A heatable mirror roller structure includes a roller body 1 and a pluggable sealing plate 2 arranged on the left side of the roller body 1, the right side of the sealing plate 2 is in contact with the left side of the roller body 1, and a heat pipe 3 is arranged inside the roller body 1.

[0018] Furthermore, a rotating block is installed on the right side of the roller body 1, and a driven gear is installed on the surface of the rotating block. The driven gear and the external driving gear are meshed and used in coordination with each other.

[0019] It also includes a fixed shaft 4, which is two in number and is respectively installed on the left and right sides of the heat-conducting pipe 3. A through groove 5 connected to the roller body 1 is opened on the left side of the sealing plate 2. The fixed shaft 4 located on the left and one end close to the through groove 5 passes through the roller body 1 and the through groove 5 in sequence and extends to the outside of the through groove 5. The fixed shaft 4 is opened at one end away from the heat-conducting pipe 3. A material guide port 100 connected to the heat-conducting pipe 3 is opened, and a plurality of annular heating blocks 6 are fixedly connected to the surface of the heat-conducting pipe 3.

[0020] Furthermore, one end of the fixed shaft 4 located on the right side and away from the heat conducting pipe 3 passes through the roller body 1 and the rotating block in sequence and extends to the outside of the rotating block.

[0021] Specifically, the high-temperature oil enters the interior of the heat pipe 3 through the material guide port 100 located on the left, and the generated high temperature is transmitted to the inner wall of the roller body 1 through the heat pipe 3. At the same time, the annular heating block 6 is started, so that the temperature of the inner wall of the roller body 1 can be further increased, thereby increasing the temperature of the surface of the roller body 1. The oil that enters the heat pipe 3 is then discharged through the material guide port 100 located on the right, so that it can be recycled.

[0022] Through the cooperation of the heat pipe 3, the fixed shaft 4, the annular heating block 6 and the material guide port 100, a heatable mirror roller structure is realized, so that external hot oil can enter the interior of the mirror roller, and the heating block can further increase the temperature of the mirror roller.

[0023] An annular block 7 is fixedly connected to the surface of the left fixed shaft 4 and inside the through groove 5. An annular groove 8 matching the annular block 7 is opened on the inner wall of the through groove 5. The side of the annular block 7 close to the annular groove 8 passes through the through groove 5 and the annular groove 8 in sequence and extends to the inside of the annular groove 8.

[0024] Furthermore, the surface of the annular block 7 and the grooves on the left and right sides are movably connected with the first steel ball 21, and the surface of the first steel ball 21 is in rolling contact with the inner wall of the annular groove 8. By providing the first steel ball 21, the friction force of the rotational contact between the annular block 7 and the annular groove 8 is reduced.

[0025] Furthermore, two annular plates 22 are fixedly connected to the surface of the fixed shaft 4 and located inside the roller body 1, and a second steel ball 23 is movably connected in the groove on the surface of the annular plate 22. One end of the second steel ball 23 close to the inner wall of the roller body 1 is in rolling contact with the inner wall of the roller body 1. By arranging the annular plate 22 and the second steel ball 23, the stability of the heat pipe 3 in the roller body 1 is improved. At the same time, the second steel ball 23 reduces the friction generated when the annular plate 22 moves.

[0026] Specifically, the external support frame supports and fixes the fixed shaft 4, and drives the driven gear to rotate through the external driving gear. The driven gear drives the roller body 1 and the sealing plate 2 to rotate through the rotating block. The sealing plate 2 drives the annular groove 8 to rotate, so that the first steel ball 21 rotates with the inner wall of the annular groove 8, and the second steel ball 23 rotates and contacts with the inner wall of the roller body 1. The fixed shaft 4, the heat pipe 3 and the annular heating block 6 do not rotate.

[0027] Two card slots 9 are provided on the right side of the sealing plate 2, and a card block 10 is fixedly connected to the left side of the roller body 1 and corresponds to the position of the card slot 9. The left side of the card block 10 penetrates the card slot 9 and extends to the inside thereof to contact the inner wall of the card slot 9. Two fixed slots 11 are provided inside the sealing plate 2. A threaded rod 12 is rotatably connected to the groove of the inner wall of the fixed slot 11 through a bearing. The end of the threaded rod 12 away from the bearing penetrates the fixed slot 11 and extends to the outside thereof to be fixedly connected to a rotating block 13. A movable plate 14 is threadedly connected to the surface of the threaded rod 12, and the surface of the movable plate 14 contacts the inner wall of the fixed slot 11. A positioning rod is fixedly connected to the bottom of the inner wall of the fixed groove 11, and the top of the positioning rod passes through the movable plate 14 and extends to the outside thereof and is fixedly connected to the inner wall of the fixed groove 11. By setting the positioning rod, the stability of the movable plate 14 during movement is improved. The side of the movable plate 14 close to the clamping block 10 is fixedly connected to the limiting block 15, and the side of the clamping block 10 close to the limiting block 15 is provided with a limiting groove 16 adapted to the limiting block 15. The side of the limiting block 15 close to the limiting groove 16 passes through the fixed groove 11, the clamping groove 9 and the limiting groove 16 in sequence and extends to the inside of the limiting groove 16 and contacts with the inner wall of the limiting groove 16.

[0028] Through the mutual cooperation of the through groove 5, the annular block 7, the annular groove 8, the clamping groove 9, the clamping block 10, the fixed groove 11, the threaded rod 12, the rotating block 13, the movable plate 14, the limit block 15 and the limit groove 16, it is convenient to disassemble the heating structure inside the roller body 1 for maintenance and overhaul, thereby improving the flexibility during use.

[0029] When in use, rotate the rotating block 13, the rotating block 13 drives the threaded rod 12 to rotate, the threaded rod 12 drives the movable plate 14 to move away from the rotating block 13, and the movable plate 14 drives the limit block 15 to move away from the limit groove 16, so that the limit block 15 and the limit groove 16 are separated, and then pull the sealing plate 2 to the left, the sealing plate 2 drives the slot 9 to move to the left, so that the slot 9 and the block 10 are separated, and the sealing plate 2 drives the fixed shaft 4 and the heat pipe 3 to move to the left through the annular block 7, so that the heat pipe 3, the fixed shaft 4, the annular plate 22 and the second steel ball 23 can be pulled out and disassembled from the inside of the roller body 1 from right to left.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
