Description

Technical Field

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

[0002] Magnetic roller, MR. The friction with the powder knife makes the toner charged. The machine charges the magnetic roller, and the friction-charged toner is adsorbed on the surface of the magnetic roller. The magnetic roller is composed of a magnetic core, a bracket, a conductive wire and a magnetic sleeve; the magnetic sleeve is composed of an aluminum layer and a coating; the coating must have a certain degree of conductivity, wear resistance and roughness. The toner in the powder bin is attracted to the surface of the magnetic roller sleeve through the internal magnetic core, and the coating on the surface of the magnetic sleeve rubs against the toner particles and the polyurethane sheet on the powder knife, so that the toner is charged with static electricity; the magnetic roller sleeve uses AC (alternating current) and DC (direct current) voltages to make the charged toner "jump" between the magnetic roller sleeve and the drum core OPC surface, so that the "static latent image" on the drum core surface is adsorbed to the toner.

[0003] During the installation of traditional magnetic rollers, the magnetic sleeve, connecting shaft and gears need to be installed layer by layer. However, the installation method between the connecting shaft and the magnetic roller is mostly directly installed by bolts. The efficiency is relatively low when the magnetic roller needs to be disassembled later during the bolt installation process, mainly because the exposed bolts are prone to rust and then get stuck.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The present application proposes a magnetic roller that is easy to install, including a magnetic roller body 1, both ends of the magnetic roller body 1 are provided with mounting mechanisms 2, the mounting mechanism 2 includes a magnetic sleeve 7, and a connecting component 8 is installed on the inner wall of one side of the magnetic sleeve 7, and a mounting shaft 6 is fixedly connected to the outer wall of one side of the magnetic sleeve 7, both ends of the magnetic roller body 1 are provided with first grooves 4, and both sides of the inner walls of the two first grooves 4 are provided with limiting grooves 5, the connecting component 8 is inserted into the first groove 4, one end of the mounting shaft 6 is provided with a second groove 9, and one side of the inner wall of the second groove 9 is rotatably connected with a connecting column 10 that drives the connecting component 8.

[0024] The magnetic roller body 1 is conveniently installed through two installation mechanisms 2. The installation mechanism 2 integrates the magnetic sleeve 7, the installation shaft 6 and the connecting component 8 together, so as to facilitate disassembly and improve the efficiency of disassembly. The connecting column 10 can be rotated to drive the connecting component 8 to be adjusted.

[0025] By inserting the connecting component 8 into the first groove 4 and utilizing the rotation of the connecting column 10 to drive the connecting component 8 to be adjusted, the rapid installation and removal of the magnetic roller is achieved, which greatly shortens the installation and removal time and improves work efficiency; the elastic member 16 in the installation groove 15 on the installation column 11 pushes the clamping seat 17 to clamp the installation column 11, which further enhances the stability of the magnetic roller during the installation process.

[0026] Preferably, the first groove 4 is a diamond groove, the second groove 9 is a circular groove, and the connecting column 10 is a diamond column.

[0027] In some embodiments, see Figure 5 The connecting component 8 includes a mounting column 11, and the cross-section of the mounting column 11 is a regular hexagonal structure.

[0028] The installation column 11 with a regular hexagonal structure is conveniently arranged to completely fit in the first groove 4 on the magnetic roller body 1, thereby avoiding slipping during rotation.

[0029] In some embodiments, see Figure 5 The inner wall of the mounting column 11 is provided with a mounting cavity, and the inner walls on both sides of the mounting cavity are rotatably connected with the same screw rod 12 .

[0030] The installation of the screw rod 12 is facilitated by the provision of the installation cavity.

[0031] In some embodiments, see Figure 5 The outer wall of the screw rod 12 is screwed with a connecting block 13, and the outer walls on both sides of the connecting block 13 are provided with sliding grooves.

[0032] The connection block 13 is directly driven to move by the rotation of the screw rod 12 .

[0034] The installation column 11 is conveniently fixed in the first groove 4 by the provision of two adjustable limiting blocks 14 , and the movement of the connecting block 13 directly drives the limiting block 14 to move.

[0035] When the connecting block 13 moves under the drive of the screw 12, it can directly drive the two limit blocks 14 to slide in the slide groove, so that the limit blocks 14 can be quickly and accurately inserted into or out of the limit groove 5 of the magnetic roller body 1, thereby realizing the rapid locking and release of the magnetic roller.

[0036] In some embodiments, see Figure 5 A mounting groove 15 is formed on the outer wall of one side of the mounting column 11 , and a pressing seat 17 is slidably connected to the inner wall of the mounting groove 15 , and a plurality of elastic members 16 are fixedly connected between the inner wall of the mounting groove 15 and the pressing seat 17 .

[0037] The elastic member 16 in the mounting groove 15 pushes the pressing seat 17, thereby facilitating the pressing of the mounting column 11 and avoiding large shaking during connection.

[0038] In some embodiments, see Figure 4 One end of the transmission shaft of the connecting column 10 is fixedly connected to the screw rod 12.

[0039] The rotation of the connecting column 10 can directly drive the screw rod 12 to rotate.

[0040] In some embodiments, see Figure 3-4A gear 3 is fixedly connected to a mounting shaft 6 in one of the mounting mechanisms 2 .

[0041] The arrangement of the gear 3 facilitates the coordination with the gear set to drive the magnetic roller to rotate.

[0042] During installation, when the magnetic roller body 1 needs to be disassembled, it is connected to the connecting column 10 through a socket wrench. When the connecting column 10 rotates, it directly drives the screw 12 to rotate, and the screw 12 rotates to drive the connecting block 13 to move. When the small head on the connecting block 13 contacts the two limit blocks 14, the two limit blocks 14 are pulled into the installation column 11. When the limit blocks 14 are away from the limit grooves 5, the magnetic roller body 1 can be disassembled. At the same time, the magnetic sleeve 7 and the gear 3 are connected to the installation shaft 6, so they can be directly disassembled.
