Description

Technical Field

[0001] The utility model relates to the technical field related to printing equipment, in particular to a magnetic roller structure which is easy to install. Background Art

[0002] As an important structure in the printing equipment, it plays a core role in the printing process. It is not only responsible for absorbing and transferring toner, but also participates in the charging process of toner and affects the printing quality by controlling the thickness of the toner layer. During the use of the printer, the magnetic roller will be installed and removed outside the toner bin due to wear of the magnetic roller, regular maintenance and toner filling.

[0003] When installing the existing magnetic roller, the magnetic roller is mostly installed and positioned through the brackets on both sides of the powder bin. However, the positioning method of the brackets on both sides of the existing magnetic roller still adopts the more traditional bolt positioning method, which results in the brackets and the powder bin being separated from each other when the magnetic roller is disassembled. As a result, when installing the brackets, it is necessary to re-position the connection between the brackets and the magnetic roller and the powder bin, which is obviously very inconvenient. For this reason, we propose a magnetic roller structure that is easy to install. Utility Model Content

[0025] 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.

[0026] See also Figure 1-7 The utility model provides a technical solution: a magnetic roller structure that is easy to install, including a powder bin 1 and a developing magnetic roller 2, with brackets 11 installed on both sides of the powder bin 1, and a rotating plate 12 rotatably installed on the outer side of the two brackets 11, and the developing magnetic roller 2 is installed between the two rotating plates 12, and an adjusting disk 3 is rotatably installed on the rear end of the powder bin 1, and the opposite end surfaces of the two brackets 11 are respectively fixedly installed with movable rods 31 inserted into the outer side of the powder bin 1. Limiting slots 32 are provided on both sides of the surface of the adjusting disk 3 in a centrally symmetrical manner, and the two limiting slots 32 are inclined. Limiting sliders 33 are fixedly installed on the periphery of the two movable rods 31, and the two limiting sliders 33 correspond to the positions of the two limiting slots 32, and the corresponding limiting slots 32 are slidably connected to the limiting sliders 33.

[0027] Working principle: When installing the developing magnetic roller 2, place the developing magnetic roller 2 at the corresponding position on the surface of the powder bin 1, and then rotate the adjusting disk 3 on the outside of the powder bin 1. The powder bin 1 is connected to the movable rod 31 through the plug-in connection between the powder bin 1 and the movable rod 31 to limit the movement direction of the movable rod 31. Since the limiting grooves 32 arranged at an angle on both sides are distributed symmetrically with the center, the rotating adjusting disk 3 can drive the two brackets 11 to move toward each other through the sliding connection between the limiting grooves 32 and the limiting sliders 33, so that the two brackets 11 are respectively plugged into the two sides of the developing magnetic roller 2, thereby achieving the effect of installing and positioning the developing magnetic roller 2.

[0028] As a further description of the above technical solution: the developing magnetic roller 2 includes a magnetic sleeve 21 and a magnetic core 22, the magnetic core 22 is rotatably installed in the magnetic sleeve 21, and a first internal connecting rod 23 is fixedly installed at one end of the magnetic sleeve 21, and a second internal connecting rod 24 is fixedly installed at one end of the magnetic core 22, and external connecting rods 13 are fixedly installed at the outer ends of the rotating plates 12 on both sides, and the first internal connecting rod 23 and the second internal connecting rod 24 are respectively plugged into the external connecting rods 13 on both sides.

[0029] Specifically, the magnetic core 22 is rotatably installed in the magnetic sleeve 21, and after the development magnetic roller 2 is installed, the first internal connecting rod 23 and the second internal connecting rod 24 are respectively plugged into the rotating plates 12 on both sides to position the magnetic core 22 and drive the magnetic sleeve 21 to rotate around the magnetic core 22. The magnetic core 22 provides magnetic force to adsorb the carbon powder inside the powder bin 1 on the surface of the magnetic sleeve 21, and the rotating magnetic sleeve 21 can evenly transfer the carbon powder to the photosensitive drum.

[0030] As a further description of the above technical solution: a limit socket 4 is provided in the middle of the inner end surface of the adjusting disk 3, a limit socket 41 is fixedly installed on the outer end surface of the powder bin 1 and is rotatably connected to the limit socket 4, and a limit rod 42 is installed between the limit socket 4 and the limit socket 41; a limit rotation cavity 43 is provided in the middle of the outer end of the adjusting disk 3, a rotating seat 44 is rotatably installed in the limit rotation cavity 43, and a threaded rod 45 is fixedly installed on one end of the rotating seat 44 and is threadedly connected to the limit rod 42; the rotating seat A first positioning hole 471 is provided on the periphery of 44, a second positioning hole 472 is provided on the periphery of the position-limiting rotating cavity 43, a position-limiting seat 46 is fixedly installed in the rotating seat 44, and positioning pins 47 are installed on both sides of the position-limiting seat 46, and the positioning pins 47 are plugged into the first positioning hole 471 and the second positioning hole 472. A dial plate 473 is fixedly installed on the periphery of the positioning pin 47, and a spring 48 is provided in the position-limiting seat 46, and the spring 48 is fixedly installed between the two positioning pins 47.

[0031] Specifically, after rotating the adjustment disk 3 to drive the bracket 11 to move and install and position the imaging magnetic roller 2;

[0032] The positioning pin 47 is pressed inward by the dial plate 473 so that it is separated from the second positioning socket 472. Then, the rotating seat 44 is rotated in the limit rotation cavity 43, driving the threaded rod 45 to rotate in the limit socket 4. The limit socket 4 is connected to the limit plug 42 through the plug connection between the limit plug 42 and the limit plug 42, which restricts the movement direction of the limit plug 42. The rotating threaded rod 45 can drive the limit plug 42 to move through the threaded connection between the limit plug 42 and the limit plug 42, so that the limit plug 42 is plugged into the limit socket 4 and the limit socket 41.

[0033] Subsequently, the shift plate 473 is released, and the spring 48 restores its deformation, driving the positioning pin 47 to move outward, so that the positioning pin 47 is re-engaged with the first positioning socket 471 and the second positioning socket 472, and then the rotating seat 44 and the limiting rod 42 can be positioned, thereby achieving the effect of positioning the rotating connection between the adjustment disk 3 and the powder bin 1.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
