Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The embodiment is basically as shown in the attached figure 1: a mechanism is changed to gravure printing roller for intaglio press, including gravure printing roller body 1, the both sides of gravure printing roller body 1 all are equipped with installation axle 2, one side fixed mounting of installation axle 2 has connecting box 3, has seted up sliding hole 4 on one side inner wall of connecting box 3, and movable mounting has two mounting brackets 5 in sliding hole 4, and one side of two mounting brackets 5 all extends to gravure printing roller body 1 in, and equal fixed mounting has the kicking block 6 that is located gravure printing roller body 1 on two mounting brackets 5, and one side that two kicking blocks 6 kept away from each other all with gravure printing roller body 1's inner wall in close contact with, and two installation axles 2 are respectively through connecting box 3 on installation gravure printing roller body 1.

In this embodiment, as shown in fig. 2, when installing, the threaded rod 16 is rotated, make the threaded rod 16 drive the mounting panel 7 to move, the mounting panel 7 moves and drives two slide bars 14 to slide in two chutes 13, thereby make the mounting panel 7 can be spacing, the mounting panel 7 moves and drives two oblique inserted bars 8 to move simultaneously, two oblique inserted bars 8 move in two oblique jacks 9, and then make two mounting brackets 5 keep away from each other, two mounting brackets 5 drive two kicking blocks 6 to keep away from each other and make the spring 12 atress tensile, thereby make the top that two kicking blocks 6 can be firm on the inner wall of gravure roller body 1, make the installation axle 2 can be convenient install on gravure roller body 1.

In this embodiment, as shown in fig. 3, when the two mounting brackets 5 move, the two mounting brackets 5 both slide on the limiting rod 11 through the limiting hole 10, so that the two mounting brackets 5 are limited to move only vertically, and further the two top blocks 6 are limited to move only vertically.

In this embodiment, as shown in fig. 4, after the two ejector blocks 6 abut against the inner wall of the gravure roller body 1, the pin rod 21 is moved so that the pin rod 21 is inserted into the corresponding one of the pin holes 20, so that the pin hole 20 can be clamped at one end of the installation shaft 2, and the threaded rod 16 is locked, so that the positions of the two ejector blocks 6 are fixed, and the installation of the gravure roller body 1 is completed.

In this embodiment, as shown in fig. 5, when the threaded rod 16 rotates, the threaded rod 16 can rotate in the circular groove 18 through the circular block 19, so that the rotation of the threaded rod 16 does not affect the mounting plate 7, and the threaded rod 16 drives the mounting plate 7 to move through the circular block 19 when being pulled or pushed.

The specific implementation is as follows:

when the gravure roller body 1 needs to be replaced, firstly, the threaded rod 16 is rotated, so that the threaded rod 16 drives the round block 19 to rotate, meanwhile, the round block 19 rotates in the round groove 18, so that the threaded rod 16 can only rotate, meanwhile, when the threaded rod 16 rotates in the threaded hole 15, the mounting plate 7 is driven to move through the round block 19, the mounting rod 7 drives the two slide rods 14 to move, so that the two slide rods 14 slide in the two sliding grooves 13, meanwhile, the mounting plate 7 moves to drive the two inclined insertion rods 8 to move, the two inclined insertion rods 8 move in the two inclined insertion holes 9, so that the two mounting frames 5 are driven to move to one side close to each other, meanwhile, under the action of the contraction force of the spring 12, the two top blocks 6 move to one side close to each other, so that the two mounting frames 5 are driven to move, and the two mounting frames 5 both vertically move on the, finally under dual effort for two kicking blocks 6 break away from with gravure roller body 1's inner wall, remove installation axle 2 this moment, make connecting box 3 remove, and then make connecting box 3 drive two kicking blocks 6 and remove gravure roller body 1, can take off gravure roller body 1 this moment and change, can make the convenient installation that installs of gravure roller body 1 like the same reason.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
