Referring to fig. 1-3, a first through hole 10 is formed in a left printer wallboard 1, one end of a roller core 3 is located inside the first through hole 10, a second through hole 11 is formed in the right printer wallboard 1, and the other end of the roller core 3 is located inside the second through hole 11;

with the above arrangement, the first through hole 10 and the second through hole 11 are provided, so that the two ends of the roll core 3 can be respectively positioned at the inner sides of the first through hole 10 and the second through hole 11 when the roll core is disassembled.

Referring to fig. 1-3, a limiting block 12 is fixedly installed on one side, away from the sleeve rubber roll 7, of the left printing machine wallboard 1, and the limiting block 12 is located above the first through hole 10;

through the structure, the limiting block 12 is arranged, so that one end of the sleeve rubber roller 7 can be limited when the sleeve rubber roller 7 is in an inclined state.

Referring to fig. 1-3, wherein a bearing is provided on the roll core 3, the roll core 3 is mounted on the impression arm sleeve 14 through the bearing;

through the structure, the bearing is arranged on the outer side of the roller core 3, and the outer ring of the bearing is in contact with the coining arm sleeve 14, so that the phenomenon that the roller core 3 is abraded with the coining arm sleeve 14 when the roller core rotates is avoided.

Referring to fig. 1-3, wherein a pulley is fixedly mounted at the right end of the right printing press wall plate 1;

through the structure, when the sleeve rubber roller 7 is separated from the roller core, the sleeve rubber roller 7 can move along the surface of the pulley through the pulley, so that the sleeve rubber roller 7 is conveniently detached.

The working principle is as follows:

the implementation steps of innovation points are as follows:

the first step is as follows: when the sleeve rubber roll 7 is disassembled, the stamping cylinder 2 can be started, the stamping cylinder 2 drives the stamping arm sleeve 14 to displace, when one end of the roll core 3 is contacted with the limiting block 12, the operation of the stamping cylinder 2 can be stopped, the stamping arm sleeve 14 and the connecting seat 15 are separated from the roll core 3, the roll core 3 can be placed in an inclined state, and the phenomenon of deviation of the roll core 3 cannot occur due to the arrangement of the limiting block 12;

the second step is that: the air pipe 5 is used for inflating the air storage cavity 4, the air in the air storage cavity 4 can be blown out through the air hole 6, the compressible fiber layer 8 is slightly thinned, and then the sleeve rubber roll 7 slides out of the roll core 3 to the right;

the third step: the sleeve rubber roller 7 can be supported by the pulleys in the dismounting process, so that a worker can conveniently dismount the sleeve rubber roller 7, and finally the dismounted sleeve rubber roller 7 can be taken out of the second through hole 11;

the fourth step: when a new sleeve rubber roll 7 is replaced, the air storage cavity 4 can be continuously inflated, the new sleeve rubber roll 7 is sleeved on the roll core 3 from the second through hole 11, when the new sleeve rubber roll 7 is completely arranged on the outer side of the roll core 3, the inflation is stopped, the compressible fiber layer 8 is restored to the original state, so that the sleeve rubber roll 7 can be limited, the assembling and disassembling cylinder 9 is started, the assembling and disassembling cylinder 9 drives the assembling and disassembling hook 13 to move upwards, the replaced new sleeve rubber roll 7 can be righted through the assembling and disassembling hook 13, the imprinting arm sleeve 14 is hung outside the bearing, the other end of the roll core 3 is limited through the connecting seat 15, finally the imprinting cylinder 2 can be started, the imprinting cylinder 2 drives the roll core 3 to be restored to the original state, the new roll core 3 can be installed, and finally the assembling and disassembling cylinder 9 drives the assembling hook 13 to move downwards, so that the normal operation of the sleeve rubber roll 7 is not affected.
