It mainly includes main machines such as the headbox, wire section, press section, drying section, calender, reel and transmission section, and is equipped with auxiliary systems such as steam, water, vacuum, lubrication and heat recovery. The process flow is as follows: the pulp is output through the headbox, dehydrated and formed in the wire section, compressed in the press section to make the paper layer uniform, dried through the pre-drying section, then enters the post-pressing section for sizing, and then enters the post-dryer for drying. The calender is then used to smooth the paper, and finally the paper is formed into a parent paper roll through the reel.

[0003] The height of the thermal guide rollers on existing papermaking machines is mostly fixed, and the height position of the thermal guide rollers cannot be quickly adjusted according to production needs. This consumes a lot of time in the process of changing the position, resulting in the problem that the thermal guide rollers are inconvenient to use. In addition, papermaking requires a large amount of water resources for production and manufacturing, and a drying process is required during the conveying process. The drying process is generally a separate mechanism, which makes the cost of papermaking high. Therefore, this application proposes another technical solution to solve the above problems.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 In this embodiment, a high-efficiency thermal guide roller for a papermaking machine includes a fixed base plate 1, and an adjusting and moving mechanism is provided on the top of the fixed base plate 1.

[0024] In embodiment one, the adjusting and moving mechanism includes two conveying rollers 2 fixedly installed on the top of the fixed base plate 1, a mounting frame 3 fixedly installed on the top of the fixed base plate 1, a mounting box 4 fixedly installed on the top of the mounting frame 3, a rotating motor 5 fixedly installed on the top of the mounting box 4, and a threaded rod 6 fixedly installed on the output shaft of the rotating motor 5 that is rotatably connected to the mounting box 4.

[0025] Among them, a bearing groove is provided on the top of the installation box 4, and the threaded rod 6 is rotatably connected to the installation box 4 through the bearing groove, which helps the rotating motor 5 to drive the threaded rod 6 to rotate. The outer side of the threaded rod 6 is threadedly connected to a threaded block 7, and a threaded groove is provided inside the threaded block 7. The threaded block 7 is threadedly connected to the threaded rod 6 through the threaded groove, which helps the threaded block 7 to move on the outside of the threaded rod 6.

[0026] In this embodiment, the bottom of the threaded block 7 is fixedly installed with a movable rod 8 extending to the installation box 4 and movably connected. A movable groove is provided at the bottom of the installation box 4. The movable rod 8 is slidingly connected to the installation box 4 through the movable groove, which helps the movable rod 8 to move. An electric push rod 9 is fixedly installed on the top of the fixed base plate 1. A thermal roller 10 is fixedly installed on the output shaft of the electric push rod 9 and the bottom of the movable rod 8. A drying component is provided on the top of the fixed base plate 1 and the inner bottom wall of the mounting frame 3.

[0027] In the second embodiment, the drying component includes a fixed box 12 fixedly installed on the top of the fixed base plate 1 and the inner bottom wall of the mounting frame 3, a blower fan 13 is fixedly installed inside the fixed box 12, an electric heating wire 14 is provided inside the fixed box 12, and a breathable cover 15 is fixedly installed on the inner wall of the fixed box 12, and a plurality of evenly arranged air holes are opened inside the breathable cover 15 to facilitate ventilation and air outlet.

[0028] Among them, the internal movable connection of the conveying roller 2 is equipped with a paper body 101 that is slidably connected to the mounting frame 3. The paper body 101 is attached to one side of the thermal roller 10. Movable grooves are provided on the left and right sides of the mounting frame 3. The paper body 101 is movably connected to the mounting frame 3 through the movable grooves, which helps to enable the paper body 101 to be movably conveyed.

[0029] It should be noted that the papermaking machine's high-efficiency thermal guide roller, through the provided adjustment and moving mechanism, uses the action of the rotating motor 5 and the threaded rod 6 to drive the movable rod 8 to drive the thermal roller 10 to move downward, and at the same time, the electric push rod 9 can be started to drive the thermal roller 10 to move upward, so that the two thermal rollers 10 process the paper body 101, which is helpful for processing paper bodies 101 of different thicknesses and sizes, and increases the flexibility of the use of the thermal roller 10. The electric heating wire 14 is used for preheating, and the blower fan 13 is started to heat the air when it passes through the electric heating wire 14. The hot air is blown to the paper body 101 through the breathable cover 15, thereby effectively air-drying the paper body 101, which helps to increase the flexibility and practicality of the device.

[0030] The working principle of the above embodiment is:

[0031] The paper machine's high-efficiency thermal guide roller can first be used to convey paper when in use. The conveying roller 2 is used to convey the paper body 101. Then the rotating motor 5 can be started to drive the threaded rod 6 to rotate. The threaded block 7 on the outside of the threaded rod 6 is lifted and moved under the limit of the movable rod 8, so that the movable rod 8 drives the thermal roller 10 to move downward. At the same time, the electric push rod 9 can be started to drive the thermal roller 10 to move upward, so that the two thermal rollers 10 process the paper body 101. Through the action of the rotating motor 5 and the threaded rod 6, the thermal roller 10 can be driven to move upward. The roller 10 moves downward, and the electric push rod 9 can be used to drive the thermal roller 10 to move upward, which is convenient for processing paper bodies 101 of different thicknesses, increasing the flexibility of the use of the thermal roller 10. When in use, the heating wire 14 can be started for preheating. When the heating wire 14 is heated, the blower fan 13 can be started, and the blower fan 13 starts to blow air. When the wind passes through the heating wire 14, it is heated, and the hot air is blown toward the paper body 101 through the breathable cover 15, thereby effectively drying the paper body 101, greatly improving the practicality of the device.
