[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0025] As Figures 1-3 shown, a cooling device for an intaglio printing press includes an inner core cylinder 1, a second cylinder 2, a third cylinder 4 and a roller shaft part 5 which are nested and assembled in sequence from the inside to the outside, wherein:

[0026] The outer wall of the inner core cylinder 1 facing the second cylinder 2 is provided with a spiral water groove 11;

[0027] The outer wall of the second cylinder 2 is provided with a plurality of curved annular grooves 21 arranged in a rectangular array and communicated with the spiral water groove 11;

[0028] The third cylinder 4 is a cylindrical grid part, and each curved annular groove 21 is located in each frame groove of the cylindrical grid part.

[0029] Specifically, the inner core cylinder 1 in the embodiment is a polyethylene plastic cylinder part, and one end is the water inlet end and the other end is the water outlet end. Thus, the liquid enters the spiral water groove 11 from the water inlet end and flows, and flows out from the other end of the spiral water groove 11, that is, from the water outlet end.

[0030] Further, the second cylinder 2 is a copper alloy part. The port of the spiral water groove 11 fits against the inner wall of the second cylinder 2, thereby forming a flowing pipeline, so that the liquid flows in the pipeline.

[0031] Secondly, the spiral water groove 11 in the embodiment is of an S-shaped structure and includes two ports, and is arranged along the water flow direction. And both ports penetrate through the second cylinder 2 and are communicated with the spiral water groove 11.

[0032] Furthermore, the third cylinder 4 in the embodiment is a ceramic part. And the cylindrical grid part fits against the inner wall of the cylinder 51 and the outer wall of the second cylinder 2, thereby forming a separate frame groove. When the liquid flows in the spiral water groove 11, the frame groove is filled, thereby cooling the cylinder 51, and the second cylinder 2 in the embodiment is a cold storage part.

[0033] Even further, the roller shaft part 5 includes a cylinder 51. The third cylinder 4 is inserted into one end of the cylinder 51, and shaft end joint parts 52 for positioning the third cylinder 4 are respectively threadedly connected to both ends of the cylinder 51. That is, when the end joint part 52 is threadedly connected to the cylinder 51, the shaft end joint part 52 positions the third cylinder 4 and restricts its circumferential rotation.

[0034] In the above-mentioned technology, the cooling water flows through the spiral water groove 11 on the outer wall of the inner core cylinder 1. During the process, the liquid in the spiral water groove 11 will also be located in a plurality of curved annular grooves 21 arranged in a rectangular array on the surface of the second cylinder 2, so that the second cylinder 2 is kept at a low temperature, and the second cylinder 2 absorbs heat from the roller shaft member 5.

[0035] Moreover, in the above-mentioned embodiment, the liquid flowing in the curved annular groove 21 will also fill the frame groove of the entire third cylinder 4. Thereby reducing the input amount of the liquid entering the cooling device during the circulation process, and saving water resources on the basis of ensuring the cooling effect.

[0036] It should be noted that the water supply for the inner core cylinder 1 in the embodiment can be connected to an external tap water pipe, or to the outlet pipe of an external water pump.

[0037] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
