[0002] Chinese patent document CN220548807U discloses a printing magnetic roller and printing apparatus, relating to the field of printing technology. The printing magnetic roller includes an air-expanding shaft and multiple arc-shaped magnetic plates arranged in a circumferential array around the air-expanding shaft. The arc-shaped magnetic plates are used to magnetically attract metal printing plates. Air pressure drives changes in the outer diameter of the air-expanding shaft to move the arc-shaped magnetic plates, so that the circumference formed by the multiple arc-shaped magnetic plates can adapt to different metal printing plates. It allows for adjustment of the outer diameter of the printing magnetic roller.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Please see Figure 1-3 This utility model provides a technical solution: a printing magnetic roller, including a printing roller 1 and a disassembly and assembly mechanism 3. A printing roller head 2 is provided on one side of the printing roller 1, and one side of the printing roller head 2 extends into the interior of the printing roller 1. The disassembly and assembly mechanism 3 is disposed inside the printing roller 1, and the disassembly and assembly mechanism 3 includes a sliding cavity 301, a movable block 302, a positioning block 304, and a limiting hole 306. Two sets of symmetrically arranged sliding cavities 301 are opened inside the printing roller head 2, and the inner walls of the two sets of sliding cavities 301 are respectively connected to a set of movable blocks 302. The outer wall of the movable block 302 is slidably connected, and a positioning insert 304 is fixedly installed on the outer wall of the movable block 302. The positioning insert 304 extends through the printing roller head 2 to the inside of the limiting hole 306. A metal printing plate 7 is magnetically attracted to the outer wall of the printing roller 1. The metal printing plate 7 is in contact with the adjacent side of the separating ring 4 but not connected. A set of mounting shafts 6 are fixedly installed on the other side of the printing roller 1 and the other side of the printing roller head 2 respectively. A gear 8 is fixedly installed on the outer wall of the printing roller 1. A magnetic component 5 is provided inside the printing roller 1.
[0023] Secondly, the disassembly and assembly mechanism 3 also includes a reset spring 303 and an auxiliary lever 305. Two sets of limiting holes 306 are provided on the outer wall of the printing roller 1. The inner wall of the sliding cavity 301 is fixedly connected to one end of the reset spring 303, and the other end of the reset spring 303 is fixedly connected to the movable block 302. A set of auxiliary levers 305 are fixedly installed on one side of each of the two sets of movable blocks 302. The auxiliary levers 305 extend to the outside of the sliding cavity 301. When the magnetic component 5 malfunctions, pressing the two sets of auxiliary levers 305 will remove the printing roller head 2 from the printing roller 1, opening the interior of the device. The operation is simple and easy to use, facilitating the maintenance of the magnetic component 5 and greatly reducing the workload of maintenance personnel.
[0024] Furthermore, two sets of partition rings 4 are fixedly installed on the outer wall of the printing roller 1 to facilitate the limiting of both sides of the metal printing plate 7, prevent the metal printing plate 7 from shifting due to friction with the printed material, make the printing process more stable, and improve the usability and practicality of the device.
[0025] A printing apparatus comprising a printing magnetic roller as described in any of the preceding claims.
[0026] Working principle: In use, the metal printing plate 7 is magnetically attached to the outer wall of the printing roller 1, with the separating ring 4 resting against both sides of the metal printing plate 7. Printing can then commence. In case of malfunction, the device is removed, and both sets of auxiliary levers 305 are simultaneously pressed towards the mounting shaft 6. This causes the movable block 302 to slide within the sliding cavity 301, thereby moving the positioning insert 304 out of the limiting hole 306, releasing the limiting effect on the printing roller head 2. The printing roller head 2 can then be removed from the printing roller 1 for re-printing. Repair or replace the magnetic component 5 inside the brush roller 1. After the repair is completed, press the two sets of auxiliary levers 305 inward to drive the movable block 302 to slide in the sliding cavity 301 and compress the reset spring 303. Then insert the printing roller head 2 into the printing roller 1, adjust the position of the positioning block 304, and under the elastic action of the reset spring 303, drive the movable block 302 to reset, so that the positioning block 304 is inserted into the limiting hole 306 to fix the printing roller head 2. The installation of the printing roller head 2 can then be completed.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
