Description

Technical Field

[0001] The utility model relates to the technical field of copier plates, and specifically relates to an adjustable cleaning blade for a copier. Background Technique

[0002] Since a copier repeatedly copies documents, after long-term use, dust is likely to adhere to the copying roller, affecting the normal use of the copier. Therefore, a cleaning blade is installed at the outer end of the copying roller of the copier to scrape off the dust on the copying roller. The commonly used cleaning blade has a horizontal straight structure and has a low adaptability to the copying roller, so the cleaning range is limited. In order to solve the above problems in the prior art, the cleaning blade is designed as an arc structure, with a height adapted to the copying roller, increasing the cleaning effect on the copying roller. However, in actual operation, since the cleaning blade is fixedly installed beside the copying roller, the angle and direction of the cleaning blade cannot be adjusted. After the position of the copying roller changes due to wear during use or maintenance, the cleaning blade no longer fits with the copying roller, resulting in the cleaning blade losing its cleaning function for the copying roller.

[0003] Based on this, an adjustable cleaning blade for a copier is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

Detailed implementation manners

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, as Figures 1-3 shown, an adjustable copier cleaning blade includes a mounting base 100, a cleaning blade 300, and an adjusting mechanism 400. A copier roller 200 is provided on the mounting base 100. A cleaning blade 300 with self-adjusting ability is provided on one side of the copier roller 200. An adjusting mechanism 400 is provided on the side of the cleaning blade 300 away from the copier roller 200. Both ends of the adjusting mechanism 400 are mounted on the mounting base 100. The mounting base 100 is provided with a limiting groove 101 and a fixing groove 102 for facilitating the installation of the adjusting mechanism 400. During installation, first install the copier roller 200, then install the cleaning blade 300 and the adjusting mechanism 400, and then adjust the installation position of the cleaning blade 300 through the adjusting mechanism 400 to make the cleaning blade 300 closely attached to the copier roller 200.

[0029] In one embodiment, as Figure 4 and Figure 5As shown in the figure, the cleaning squeegee 300 includes a mounting plate 301 and a squeegee 302. The mounting plate 301 is an arc-shaped bent plate. The squeegee 302 is fixed to the concave surface of the mounting plate 301. The squeegee 302 is rotatably connected to a base 303 fixed on the mounting plate. On one side of the squeegee 302 close to the mounting plate 301, two first springs 304 are symmetrically arranged. One end of the first spring 304 is fixed to the squeegee 302, and the other end is fixed to the mounting plate 301. During use, under the action of the first spring 304, the squeegee 302 will always be in close contact with the copier roller 200, thus ensuring the cleaning effect.

[0030] In one embodiment, as Figure 4 shown, three rows of squeegees 302 are evenly arranged on the mounting plate 301, and the squeegees 302 in each row are alternately staggered. By arranging three rows of squeegees 302, the cleaning quality of the copier roller 200 can be effectively improved.

[0031] In one embodiment, as Figure 5 shown, on one side of the convex surface of the mounting plate 301, there are a chute 305 and a tooth groove 306. There are two symmetrically arranged chutes 305 and tooth grooves 306. The chute 305 is used to fix and limit the movement of the adjusting mechanism 400, and the tooth groove 306 meshes with a gear 408 in the adjusting mechanism 400.

[0032] In one embodiment, as Figure 6 and Figure 7 shown, the adjusting mechanism 400 includes a frame 401, a fixing component, and an adjusting component. The frame 401 is fixed on the mounting plate 301. The fixing components are symmetrically arranged at both ends of the frame 401, and the adjusting component is arranged in the middle of the frame 401. The adjusting mechanism 400 is fixed on the mounting seat 100 through the fixing components, and both the fixing component and the adjusting component are installed in the inner cavity of the frame 401.

[0033] In one embodiment, as Figure 6 shown, the fixing component includes a fixing rod 402 and a second spring 403. One end of the fixing rod 402 passes through a sealing plate 413 at the end of the frame 401 and is fixed to a first movable plate 404. The first movable plate 404 is arranged in the inner cavity of the frame 401. The second spring 403 is arranged on the side of the first movable plate 404 away from the fixing rod 402. On the other side of the second spring 403, there is a first limiting plate 405. On the side of the first limiting plate 405 away from the second spring 403, there is a second movable plate 407. The first movable plate 404 and the second movable plate 407 are connected by a connecting rod 406. During installation, the second movable plate 407 is pulled inward, driving the fixing rod 402 to shorten towards the frame 401. Then the entire adjusting mechanism 400 is installed on the fixing seat 100. After releasing the second movable plate 407, the fixing rod 402 is inserted into a fixing groove 102 on the fixing seat 100 under the action of the second spring 403, completing the installation of the adjusting mechanism 400.

[0034] In one embodiment, as Figure 6 shown, the adjusting assembly includes a gear 408, a rotating shaft 409, and a dial 410. The position of the gear 408 is corresponding to the tooth groove 306 on the mounting plate 301. The rotating shaft 409 is arranged between two gears 408. The dial 410 is fixed at the center of the rotating shaft 409. There is a second limiting plate 411 on each side of the dial 410. During installation, by rotating the dial 410, the gear 408 is driven to rotate, thereby driving the cleaning blade 300 to adjust the position of the cleaning blade 300.

[0035] In one embodiment, as Figure 6 and Figure 7 shown, there are four T-shaped protrusions 412 symmetrically arranged on the frame 401. The position of the T-shaped protrusions 412 is corresponding to the sliding groove 305 on the mounting plate 301. When the position of the cleaning blade 300 is adjusted by the adjusting assembly, the cleaning blade 300 will move relative to the frame 401 along the sliding groove 305.

[0036] The above embodiment discloses an adjustable cleaning blade for a copier. During use, first, the copier roller 200 is installed on the mounting base 100. Then, the cleaning blade 300 and the adjusting mechanism 400 are combined into a whole through the T-shaped protrusions 412. Then, the whole cleaning blade 300 and the adjusting mechanism 400 are installed on the mounting base 100. During installation, first, the second movable plate 407 is pulled inward to drive the fixing rod 402 to shorten towards the frame 401. Then, the whole adjusting mechanism 400 is installed on the fixing base 100. The second movable plate 407 is released. Under the action of the second spring 403, the fixing rod 402 is snapped into the fixing groove 102 on the fixing base 100 to complete the installation of the cleaning blade 300 and the adjusting mechanism 400. Then, according to the positions of the cleaning blade 300 and the copier roller 200, the dial 410 is rotated to move the cleaning blade 300 up and down relative to the adjusting mechanism 400 until the blade 302 in the cleaning blade 300 is in close contact with the copier roller 200.

[0037] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
