The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1:

[0023] Please see Figures 1-4As shown, this utility model provides a dual-frequency hot roller structure for a three-color printing press, including a hot roller body 1, of which there are two. A mounting plate 4 is movably connected to the back of the hot roller body 1 via bearings. A fixed seat 2 is movably connected between the surfaces of the two mounting plates 4. A locking hole 7 is provided on the surface of the mounting plate 4 and behind the fixed seat 2. A fixed shell 3 is fixedly connected to the middle of the back of the fixed seat 2. L-shaped moving rods 6 are movably connected to both sides of the fixed shell 3. A locking block 8 is fixedly connected to the side of the two L-shaped moving rods 6 that is far apart from each other. The surface of the locking block 8 is movably connected to the surface of the locking hole 7. Adjusting screws 9 are movably connected to both sides of the inner cavity of the fixed shell 3 via bearings. The surface of the L-shaped moving rods 6 is threadedly connected to the surface of the adjusting screws 9. A second bevel gear 14 is fixedly installed on the side of the two adjusting screws 9 that is close to each other. A rotating sleeve 11 is movably connected to the middle of the front surface of the fixed seat 2 via bearings. A first bevel gear 13 is fixedly installed on the outer surface of the rotating sleeve 11. A rotating shaft 12 is movably connected to the inner cavity of the rotating sleeve 11.

[0024] In this technical solution, the fixed base 2 and the mounting plate 4 can support the power frequency hot roller body 1. At the same time, the locking holes 7 and the locking blocks 8 can limit the movement between the power frequency hot roller body 1, the mounting plate 4 and the fixed base 2, preventing the power frequency hot roller body 1 from shifting or shaking during use. The rotating shaft 12, rotating sleeve 11, first bevel gear 13, second bevel gear 14, adjusting screw 9, L-shaped moving rod 6 and locking blocks 8 can achieve the purpose of quick disassembly of the power frequency hot roller body 1. The operation is convenient and quick, bringing great convenience to the maintenance work of personnel.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 3 and Figure 4 As shown, limiting blocks 18 are fixedly connected to both sides of the inner cavity of the rotating sleeve 11, and limiting grooves 20 are opened on both sides of the rotating shaft 12. The surface of the limiting block 18 is movably connected to the surface of the limiting groove 20. A support spring 19 is fixedly connected to the back of the limiting block 18, and the back of the support spring 19 is fixedly connected to the surface of the limiting groove 20. A control turntable 17 is fixedly connected to the front surface of the rotating shaft 12. Pin blocks 15 are fixedly connected to both ends of the back of the rotating shaft 12. A pin hole 16 is opened at the middle of the inner cavity of the fixed shell 3. There are two pin holes 16, and the surface of the pin block 15 is movably connected to the surface of the pin hole 16.

[0027] In this technical solution, the limiting block 18 and the limiting groove 20 can limit the movement between the rotating shaft 12 and the rotating sleeve 11, so that the rotating sleeve 11 can be rotated when the operator rotates the rotating shaft 12. The supporting spring 19 allows the pin 15 to be inserted into the pin hole 16 under the tension of the supporting spring 19. The pin 15 and the pin hole 16 limit the rotation direction of the rotating shaft 12, preventing the rotating shaft 12 from rotating due to accidental contact. The operating turntable 17 facilitates the operator to rotate the rotating shaft 12.

[0028] Example 3:

[0029] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, two adjusting screws 9 are movably connected to a support plate 10 via bearings at their close ends. The back of the support plate 10 is fixedly connected to the inner cavity of the fixed shell 3. Positioning frames 5 are fixedly connected to both ends of the front surface of the fixed seat 2. The surface of the mounting plate 4 is movably connected to the inner cavity of the positioning frame 5. The first bevel gear 13 meshes with the second bevel gear 14, and the transmission ratio between the first bevel gear 13 and the second bevel gear 14 is 1.

[0030] In this technical solution, the support plate 10 is used to support the adjusting screw 9 and prevent the adjusting screw 9 from tilting due to force. The positioning frame 5 is used to position the mounting plate 4 and the fixed seat 2 and prevent the mounting plate 4 from shifting along the surface of the fixed seat 2.

[0031] The working principle of this utility model is as follows: The fixed base 2 and mounting plate 4 support the power frequency hot roller body 1. Simultaneously, the locking holes 7 and 8 limit the movement of the power frequency hot roller body 1, mounting plate 4, and fixed base 2, preventing displacement and shaking of the power frequency hot roller body 1 during use. Furthermore, when personnel need to disassemble and maintain the power frequency hot roller body 1 later, the rotating shaft 12 is pulled to move it, causing the pin block 15 to disengage from the pin hole 16. The rotating shaft 12 is then manipulated to rotate, driving the rotating sleeve 11 and the first bevel gear 13. While rotating, the first bevel gear 13 rotates, which drives the second bevel gear 14 and the adjusting screw 9 to rotate. Under the action of the adjusting screw 9, the two sets of L-shaped moving rods 6 and the locking block 8 can move towards each other until the locking block 8 can disengage from the surface of the locking hole 7, thereby releasing the limit of the mounting plate 4 and the power frequency hot roller body 1. Then, the personnel can remove the power frequency hot roller body 1 and the mounting plate 4 from the front of the fixed seat 2, thereby achieving the purpose of quick disassembly of the power frequency hot roller body 1. The operation is convenient and quick, bringing great convenience to the personnel's maintenance work.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
