[0028] As Figures 1-7The utility model discloses a kind of stable connection's printing plate roller, including the roller body 1 being set as cylinder, the printing sleeve 2 of the circumferential sleeve roller body 1, the front mounting shaft 3 and rear mounting shaft 4 located at the front and back of roller body 1, the axial direction of roller body 1 extends along front and back, after the front mounting shaft 3 and rear mounting shaft 4 are respectively installed into the frame body for installing printing plate roller, one end of mounting shaft can be subjected to torque, further drive roller body 1 and printing sleeve 2 to rotate, so that the graphic information on printing sleeve 2 is printed on the file to be printed after being attached with ink (this is prior art, not specific elaboration here), the front mounting disc 31 of the rear side of the front mounting shaft 3, the rear mounting disc 41 of the front side of the rear mounting shaft 4, the front mounting disc 31 is sleeved printing sleeve 2 front side and with printing sleeve 2 by snap fit etc. detachable connection, the rear mounting disc 41 is sleeved printing sleeve 2 rear side and with printing sleeve 2 snap fit etc. detachable connection, since printing sleeve 2 is located at the outer periphery of roller body 1 during assembly, at this time, front mounting disc 31 and rear mounting disc 41 are respectively sleeved in front and back of printing sleeve 2, at this time, limited by front mounting disc 31 and rear mounting disc 41, printing sleeve 2 will not be separated from roller body 1, and because front mounting disc 31 and rear mounting disc 41 are sleeved printing sleeve 2, the contact area of front mounting disc 31, rear mounting disc 41 and printing sleeve 2 is increased, and then the fixing of front mounting disc 31, rear mounting disc 41 and printing sleeve 2 is realized, to further improve the connection stability of front mounting disc 31, rear mounting disc 41 and printing sleeve 2.

[0029] Wherein, the front mounting disc 31 is made of rubber and is provided with a limiting ring 311 protruding inwardly, the printing sleeve 2 is provided with a limiting groove 21 corresponding to the limiting ring 311, the printing sleeve 2 is provided with a plurality of rotation-stopping plug blocks 22 protruding therefrom, the front mounting disc 31 is provided with a rotation-stopping plug groove 312 corresponding to each rotation-stopping plug block 22, the rear mounting disc 41 is the same in shape and size as the front mounting disc 31, since the front mounting disc 31 is made of rubber, in the process of installing the front mounting disc 31 in front of the printing sleeve 2, the limiting ring 311 protruding inwardly of the front mounting disc 31 needs to be deformed outwardly under force and then fall into the limiting groove 21 by passing the front side of the printing sleeve 2, at this time, the front and back of the limiting ring 311 will be limited by the printing sleeve 2 and cannot move forward and backward, thereby facilitating the fixing of the front mounting disc 31 and the printing sleeve 2, and after each rotation-stopping plug block 22 enters the corresponding rotation-stopping plug groove 312, the front mounting disc 31 cannot rotate compared with the printing sleeve 2, thereby further improving the connection stability of the front mounting disc 31 and the printing sleeve 2.

[0030] Preferably, the width of the inner side of the limiting ring 311 is smaller than the width of the fixed side of the front mounting disc 31. Since the width of the inner side of the limiting ring 311 is smaller than the width of the fixed side of the front mounting disc 31, the outer side can be stably attached to the front mounting disc 31 and fixed together, and the inner side enables the limiting ring 311 to be more smoothly aligned with the limiting groove 21, thereby enabling the limiting ring 311 to enter the limiting groove 21.

[0031] Preferably, each of the rotation-stopping plug blocks 22 is in the shape of a hemisphere with the opening facing backward and is fixedly connected to the roller body 1 by welding, integral molding or the like. Since each of the rotation-stopping plug blocks 22 is in the shape of a hemisphere with the opening facing backward, during the process of mounting the front mounting disc 31 on the printing sleeve 2, the foremost side of each of the rotation-stopping plug blocks 22, i.e., the foremost side of the hemisphere, enters the corresponding rotation-stopping plug groove 312 first, thereby enabling the rotation-stopping plug blocks 22 to be more smoothly aligned with the corresponding rotation-stopping plug groove 312 and then inserted, so as to determine the position of the front mounting disc 31 on the printing sleeve 2 and then fix the front mounting disc 31 on the printing sleeve 2 by bolts, magnetic attraction or the like.

[0032] Preferably, the front mounting disc 31 comprises a shielding surface 313 on the front side, and the projection of each of the rotation-stopping plug blocks 22 on the front side falls on the shielding surface 313. Since the projection of each of the rotation-stopping plug blocks 22 on the front side falls on the shielding surface 313, after the position of the front mounting disc 31 on the printing sleeve 2 is determined, each of the rotation-stopping plug blocks 22 is not exposed to the outside, thereby improving the aesthetic appearance.

[0033] In addition, the printing sleeve 2 comprises an upper mounting section 23 and a lower mounting section 24, the front mounting disc 31 is sleeved on the front side of the upper mounting section 23 and the rear mounting section, and the rear mounting disc 41 is sleeved on the rear side of the upper mounting section 23 and the rear mounting section. The upper mounting section 23 and the lower mounting section 24 are detachably connected by magnetic attraction, buckling or the like. Since the upper mounting section 23 and the lower mounting section 24 located in the circumferential direction of the roller body 1 are detachably connected, when the printing plate roller is not used, in addition to dismounting the front mounting shaft 3 and the rear mounting shaft 4, the upper mounting section 23 and the lower mounting section 24 can also be separated, thereby further facilitating the storage of the printing plate roller. In addition, the detachable upper mounting section 23 and lower mounting section 24 enable the printing sleeve 2 with different printing patterns to be replaced, thereby facilitating the printing work.

[0034] The right side of the upper mounting section 23 is provided with a right mounting plug 231 protruding downward, the left side of the lower mounting section 24 is provided with a left mounting plug 241 protruding upward, the upper mounting section 23 is provided with a left mounting slot 232 corresponding to the left mounting plug 241, and the lower mounting section 24 is provided with a right mounting slot 242 corresponding to the right mounting plug 231. After the upper mounting section 23 is mounted above the lower mounting section 24, the right mounting plug 231 on the upper mounting section 23 is mounted into the right mounting slot 242, and the left mounting plug 241 on the lower mounting section 24 falls into the left mounting slot 232 of the upper mounting section 23, so that the relative position of the upper mounting section 23 and the lower mounting section 24 is determined. After the front mounting disc 31 and the rear mounting disc 41 are mounted on the front and rear sides of the upper mounting section 23 and the lower mounting section 24 respectively, the upper mounting section 23 and the lower mounting section 24 are fixed, and the two are stably connected together without external force.

[0035] The upper mounting section 23 and the lower mounting section 24 are provided with protruding beams 25, and the roller body 1 is provided with a plurality of matching grooves 11 for inserting the protruding beams 25. Since the protruding beams 25 on the upper mounting section 23 and the lower mounting section 24 are inserted into the matching grooves 11 on the roller body 1, the upper mounting section 23 and the lower mounting section 24 cannot rotate relative to each other under the action of the protruding beams 25 when the relative position of the upper mounting section 23 and the lower mounting section 24 is determined, thereby facilitating the determination of the position of the upper mounting section 23 and the lower mounting section 24.

[0036] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application.
