[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art belong to the protection scope of the utility model.

[0021] Embodiment of the utility model:

[0022] Embodiment one

[0023] A kind of cooling device of cylinder dryer carrier roller, including dryer cylinder 1 (dryer cylinder 1 has belonged to prior art, this application does not carry out detailed repetition);Belt 5 is installed on dryer cylinder 1, the lower part of dryer cylinder 1 is symmetrically equipped with support frame 2, support frame 2 is installed on the mounting bracket (not shown in the figure) of the lower part of dryer cylinder 1;And two bearings 3 are installed on each support frame 2, and the same drag wheel 4 is installed between two bearings 3, and drag wheel 4 is in contact with belt 5, to play the role of supporting dryer cylinder 1;

[0024] Specifically: support frame 2 includes bottom plate 21, and two parallel side plates 22 are fixed on bottom plate 21, first mounting hole is formed in the upper portion of each side plate 22, and bearing 3 is installed in the inside of first mounting hole;It should be noted that: rib plate 23 is arranged between side plate 22 and bottom plate 21, to play the role of reinforcing side plate 22, to prevent deformation due to excessive bearing capacity of side plate 22;

[0025] Specifically: drag wheel 4 includes shaft 41 and runner 42, it should be noted that: shaft 41 and runner 42 are integrally made when processing, without welding the connection of shaft 41 and runner 42;The advantages of this kind of production are: good firmness, reduce the occurrence of welding failure;In addition, it has good conductivity, improves the heat dissipation effect of bearing 3.

[0026] Example two

[0027] The dryer cylinder 1 of the above example one can generate a large amount of heat when used for a long time, which increases the temperature around. In addition, the drum dryer 1 also transmits its heat to the drag wheel 4, so that the drag wheel 4 can transmit heat to the bearing 3. If the bearing 3 is used in a high temperature state for a long time, it is easy to be damaged, which shortens the service life of the bearing 3. Therefore, in order to solve the above-mentioned problems, the example one is improved.

[0028] A storage box 6 is placed on the top of the bottom plate 21, the storage box 6 is located between the two side plates 22 and directly below the drag wheel 4, and the top of the storage box 6 is provided with an opening, and the inside of the storage tank 6 stores a cooling liquid, which can be cooling oil. The lower portion of the runner 42 penetrates the opening and is immersed in the cooling liquid. The cooling liquid can cool the drag wheel 4. The cooled drag wheel 4 conducts heat to the bearing 3, which can indirectly cool the bearing 3, reduce the damage of the bearing 3, and prolong the service life of the bearing.

[0029] Example three

[0030] Although the above-mentioned embodiment two can play a role in cooling the bearing 3 and the drag wheel 4, when the lower part of the drag wheel 4 is in contact with the cooling liquid and rotates, the drag wheel 4 will take a large amount of cooling liquid out of the storage box 6 and fall outside the storage box 6, which not only causes waste of cooling liquid, but also leads to a poor sanitary environment. Therefore, in order to solve the above-mentioned technical defects, the embodiment two is improved again.

[0031] Two "L" limit rods 10 are fixed on the top of the storage box 6 along the length of the two sides, and two installation plates 7 are slidingly installed between the two limit rods 10. Through the setting of the limit rods 10, the installation plates 7 are limited, which reduces the shaking of the installation plates 7 during use. It should be noted that the opposite sides of the two installation plates 7 are provided with notches 8. When the two installation plates 7 are closed, the two notches 8 form a square slot opposite the opening, which can ensure that the lower part of the drag wheel 4 extends into the storage box 6. The edge of the notch 8 is provided with a sponge 9, and the sponge 9 is in contact with the lower part of the rotating wheel 42. Through the setting of the sponge 9, the cooling liquid on the rotating wheel 42 is wiped, which avoids the cooling liquid from being taken into the outside of the storage box 6 when the rotating wheel 42 rotates, and reduces the phenomenon of cooling liquid dropping everywhere. On the one hand, it reduces the waste of cooling liquid, and on the other hand, it can ensure a good sanitary environment around. The end of the storage box 6 is fixed with an installation column 11, and the installation plate 7 is provided with a second installation hole. The installation column 11 is threadedly installed with a butterfly nut 12 through the second installation hole. Through the cooperation of the installation column 11 and the butterfly nut 12, the installation plate 7 can be quickly disassembled and the sponge 9 can be replaced.

[0032] When the sponge 9 is replaced after use, the butterfly nut 12 is loosened, the installation plate 7 is taken out from between the two limit rods 10, and then the sponge 9 is replaced. This replacement method is simple and does not need to disassemble the bearing 3 and the drag wheel 4, thereby providing convenience for the staff.
