Accordingly, the scope of the application should be considered in all of its aspects as defined by the appended claims.

[0029] In order to make the technical person in the art better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0030] Note: the examples to be introduced next are only a specific example, and not as a limitation on the embodiments of the present application must be as follows specific steps, values, conditions, data, order, etc. The skilled person in the art can use the concept of the present application to construct more embodiments not mentioned in the present specification by reading the present specification.

[0031] When needed to use, the length and radius of the compression roller are fixed in design, and it is impossible to select a more suitable length and diameter of the plate roller for use in the field production, that is, there are the following shortcomings: the length of the compression roller is fixed, and it is not matched in the production process of foil with different widths; the radius of the compression roller is fixed, and it is impossible to select the most suitable radius roller for use in the production process; and the cost is high when changing or newly making the plate roller. Therefore, an assembled intaglio coater compression roller is needed to solve the above problems.

[0032] In order to solve the problems existing in the compression roller of the coater, the present application provides an assembled intaglio coater compression roller.

[0033] Please refer to Figure 1 , including a coater compression roller and a center spindle 6 inserted into the coater compression roller, the coater compression roller is arranged as a printing cylinder 5, the printing cylinder 5 is sleeved on the outside of the center spindle 6, and the center of the printing cylinder 5 corresponds to the center of the center spindle 6, the outside of the center spindle 6 is sleeved with two clamping assemblies, and the two clamping assemblies are arranged at both ends of the printing cylinder 5.

[0034] As Figure 1As shown, the impression cylinder 5 is in a cylindrical structure, and a hole is formed in the middle part, so that the impression cylinder 5 is sleeved on the outside of the center spindle 6, and the center of the impression cylinder 5 corresponds to the center of the center spindle 6, so that the impression cylinder 5 and the center spindle 6 are connected in a detachable manner, that is, during use, the appropriate impression cylinder 5 can be selected and installed on the center spindle 6 for use, and the clamping assembly is arranged at both ends of the impression cylinder 5 to clamp and fix the impression cylinder 5, preventing the impression cylinder 5 from moving left and right on the center spindle 6 and rotating by itself, which causes the impression cylinder 5 to be unable to be used.

[0035] Please continue to refer to Figure 1 , the clamping assembly includes a gasket 7 attached to one end of the impression cylinder 5 and a fixed nut 8 arranged on one side of the gasket 7, both the gasket 7 and the fixed nut 8 are in a circular ring structure, the outer ring part of the gasket 7 is arranged as a rubber structure, and the inner ring part of the gasket 7 is arranged as a steel structure, a part of the outside of the center spindle 6 is provided with a thread, the fixed nut 8 is threadedly connected with the center spindle 6, and the circular ring diameter of the fixed nut 8 is smaller than that of the gasket 7.

[0036] As shown in Figure 1 , the clamping assembly is mainly composed of the gasket 7 and the fixed nut 8, the gasket 7 is sleeved on the outside of the center spindle 6, and the spring is at one end of the impression cylinder 5, and the fixed nut 8 is arranged on one side of the gasket 7, so that the fixed nut 8 clamps the gasket 7 and the impression cylinder 5, that is, the outside of the center spindle 6 is provided with a thread, and when the fixed nut 8 rotates and moves on the center spindle 6, the fixed nut 8 gradually approaches the impression cylinder 5 to fix it, and the gasket 7 is arranged between the fixed nut 8 and the impression cylinder 5 to clamp and protect the impression cylinder 5. Because the outer ring part of the gasket 7 is a rubber structure, it can provide more stable clamping, anti-skid and protection, and the inner ring steel structure of the gasket 7 can provide a hard clamping effect.

[0037] Please continue to refer to Figure 1 , the center spindle 6 has a boss extending along the length direction of the center spindle 6, and the diameter of the boss is smaller than that of the center spindle 6, the cross section of the connection between the boss and the center spindle 6 is in a stepped structure, and the outside of the boss is provided with a transmission bearing 9.

[0038] As shown in Figure 1 , the center spindle 6 has a boss extending out at both ends, so that the boss and the center spindle 6 are in a stepped structure, that is, when the transmission bearing 9 is arranged on the boss, the stepped structure can limit the transmission bearing 9, and the transmission bearing 9 is arranged on a mechanism that can move up and down, such as a gas cylinder (prior art), so that the height of the impression cylinder 5 can be adjusted.
