Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0025] Next, in conjunction with the attached Figure 1 to the attached Figure 4 and specific embodiments, the present invention will be described in detail.

[0026] As Figures 1 to 4 shown, a roller lubrication device for a cylindrical screen provided by the present invention includes a base 1. The roller 2 of the cylindrical screen is placed above the base 1. The upper surface of the base 1 is fixedly connected with a support plate 11, and the roller 2 is rotatably connected to the support plate 11. The upper surface of the base 1 is fixedly connected with a support seat 3. The upper surface of the support seat 3 is provided with an oil storage tank 31 downward. The idler roller 4 is placed in the oil storage tank 31, and the idler roller 4 is rotatably connected to the support seat 3. The roller 2 abuts against the idler roller 4, and the idler roller 4 supports the roller 2.

[0027] The side wall of the support plate 11 is fixedly connected with a protective cover 5. An oil replenishing pipe 6 is penetrated through the protective cover 5, and the oil replenishing pipe 6 is fixedly connected with the protective cover 5. The lower end of the oil replenishing pipe 6 is placed above the oil storage tank 31. The upper end of the oil replenishing pipe 6 is fixedly connected with an oil storage tank 7, and the oil replenishing pipe 6 is internally communicated with the oil storage tank 7. The top of the oil storage tank 7 is open. One side of the protective cover 5 close to the oil storage tank 7 is fixedly connected with a support rod 71, and one end of the support rod 71 away from the protective cover 5 is fixedly connected with the oil storage tank 7.

[0028] The staff adds lubricating oil into the oil storage tank 7 from the top of the oil storage tank 7. The lubricating oil flows into the oil storage tank 31 after passing through the oil replenishing pipe 6. The idler 4 is in contact with the lubricating oil in the oil storage tank 31. The lubricating oil lubricates the connection between the idler 4 and the roller 2. During the process of adding lubricating oil to the idler 4, the excess lubricating oil is stored in the oil storage tank 31, reducing the waste of lubricating oil. The lubricating oil in the oil storage tank 31 can be used for a relatively long time without the staff frequently adding lubricating oil. When the amount of lubricating oil in the oil storage tank 31 is insufficient, the staff only needs to replenish the lubricating oil into the oil storage tank 7, reducing the labor intensity of the staff.

[0029] A valve 61 is fixedly installed on the oil replenishing pipe 6. The staff adds lubricating oil into the oil storage tank 7 in advance. When it is necessary to add lubricating oil into the oil storage tank 31, the valve 61 is opened, and the lubricating oil in the oil storage tank 7 can flow into the oil storage tank 31 through the oil replenishing pipe 6. When the lubricating oil in the oil storage tank 31 is added, the valve 61 is closed.

[0030] A cover plate 8 is rotatably connected to the top of the oil storage tank 7. A handle 81 is fixedly connected to the upper surface of the cover plate 8. The lower surface of the cover plate 8 abuts against the upper surface of the oil storage tank 7. The cover plate 8 closes the oil storage tank 7, reducing the possibility of impurities entering the interior of the oil storage tank 7. A fixing component 9 is provided between the cover plate 8 and the oil storage tank 7. When the cover plate 8 closes the oil storage tank 7, the fixing component 9 fixes the cover plate 8, increasing the stability when the cover plate 8 closes the oil storage tank 7.

[0031] When it is necessary to add lubricating oil into the oil storage tank 7, the fixing component 9 releases the restriction on the cover plate 8. The staff holds the handle 81 and rotates the cover plate 8 upward to open the oil storage tank 7, and then adds lubricating oil into the oil storage tank 7.

[0032] The fixing component 9 includes a fixing plate 91 fixedly connected to the side wall of the oil storage tank 7. A fixing block 92 is fixedly connected to the upper surface of the fixing plate 91. A plugging slot 921 is provided on the side of the fixing frame close to the cover plate 8. A pressing rod 93 is slidably plugged in the plugging slot 921. A spring 94 is fixedly connected to the side of the pressing rod 93 away from the cover plate 8. One end of the spring 94 away from the pressing rod 93 is fixedly connected to the bottom of the plugging slot 921.

[0033] An inclined surface 931 is provided on the side of the pressing rod 93 close to the cover plate 8. A connecting plate 95 is fixedly connected to the side of the cover plate 8 close to the pressing rod 93. When the cover plate 8 is rotated downward to close the oil storage tank 7, the connecting plate 95 contacts the inclined surface 931. The connecting plate 95 continues to move downward. Under the action of the inclined surface 931, the pressing rod 93 moves away from the cover plate 8. At this time, the spring 94 is compressed. When the connecting plate 95 passes over the inclined surface 931, under the action of the spring 94, the pressing rod 93 moves toward the cover plate 8. The lower surface of the pressing rod 93 abuts against the upper surface of the connecting plate 95, and the pressing rod 93 fixes the connecting plate 95, thereby fixing the cover plate 8.

[0034] A shift lever 932 is fixedly connected to the upper surface of the compression bar 93. When it is necessary to rotate the cover plate 8 upward to open the oil storage tank 7, the shift lever 932 is moved to the side away from the cover plate 8. The shift lever 932 drives the compression bar 93 to move to the side away from the cover plate 8, separating the compression bar 93 from the cover plate 8, and then the cover plate 8 can be rotated upward to open the oil storage tank 7.

[0035] The implementation principle of a cylindrical screen idler lubrication device provided by the present utility model is as follows: Rotate the cover plate 8 upward to open the oil storage tank 7. The staff adds lubricating oil into the oil storage tank 7, and then rotates the cover plate 8 downward so that the lower surface of the compression bar 93 abuts against the upper surface of the connecting plate 95, and the compression bar 93 fixes the cover plate 8. Open the valve 61, and the lubricating oil inside the oil storage tank 7 flows into the oil storage groove 31 through the oil replenishing pipe 6. The oil storage groove 31 is filled with lubricating oil, and then close the valve 61. The lubricating oil in the oil storage groove 31 lubricates the idler 4.

[0036] The above further describes the present utility model with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
