Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

As shown in fig. 1, for the ink cooling device for gravure printing provided by the present invention, including an ink tank 1, the sidewall and the bottom of the ink tank 1 are both of a double-layer structure having an interlayer 4, and are divided into an inner cavity 2 and an outer wall 3, the interlayer 4 between the inner cavity 2 and the outer wall 3 is internally provided with a refrigerant (not shown in the figure), and the upper portion of the outer wall 3 of the ink tank 1 is provided with a filling port 6 for putting in the refrigerant; the ink box is characterized by further comprising a hollow heat conduction pipe 5, the heat conduction pipe 5 is wound on the inner cavity 2 of the ink box 1, a water inlet 7 and a water outlet 8 are formed in the lower portion of the outer wall 3 of the ink box 1, and the water inlet 7 and the water outlet 8 are communicated with one end of the heat conduction pipe 5 respectively.

In this embodiment, the heat pipe 5 is wound in a serpentine shape around the inner cavity 2 of the ink tank 1. The heat conduction pipe is arranged in such a way that the heating surface of the heat conduction pipe can be increased and the heat conduction pipe is not limited to a certain specific part of the inner cavity of the ink box.

In this embodiment, heat pipe 5 is tightly attached to inner cavity 2 of ink tank 1. The purpose makes heat pipe and inner chamber contact better, is convenient for carry out the heat exchange.

In this embodiment, a water outlet 9 is provided at the bottom of the outer wall 3 of the ink tank 1, and the water outlet is closed by a rubber plug (not shown). In actual work, the refrigerant in the intermediate layer of ink tank can use very long a period, unless the poor situation that causes the refrigerant to leak because of ink tank's seal, otherwise need not change the refrigerant basically, but the utility model discloses still select to set up a outlet in ink tank's outer wall bottom, can make things convenient for the washing of change and ink tank of refrigerant after like this.

It should be noted that the heat conduction pipe 5 of the present invention is made of a copper pipe. The copper pipe not only has better heat-conducting property, but also has lower cost.

It should be noted that the refrigerant of the present invention is water. The water can be tap water or purified water, is a common refrigerant medium, has low cost and easy acquisition compared with other refrigerant media such as ethanol and glycol, can be repeatedly used, and saves resources.

The utility model provides a printing ink cooling device for intaglio printing simple structure, the function is convenient, it is specific, drop into the intermediate layer 4 between inner chamber 2 and the outer wall 3 of ink tank 1 from filler 6 with the refrigerant earlier, water inlet 7 and delivery port 8 all are external quick-operation joint, convenient operation, and intaglio printing machine itself is from having endless cooling water system, introduce heat pipe 5 with this cooling water through water inlet 7, get back to the intaglio printing machine cooling water system from delivery port 8 again, can not waste water like this, the water cost has been practiced thrift. Because heat pipe 5 has good thermal conductivity, heat pipe 5 that twines on inner chamber 2 can carry out the heat exchange with inner chamber 2, just so make the printing ink temperature in 1 inner chamber 2 of ink tank reduce (the utility model discloses a specific structure of ink tank is not big with the structure of the ink tank of current gravure press, and printing ink is splendid attire in the inner chamber of ink tank), and the cooling water that the circulation was introduced in heat pipe 5, then can dispel the heat to heat pipe 5 that has absorbed the heat, and heat pipe 5 is in the refrigerant medium again, under the complete parcel of refrigerant medium, the heat that absorbs on heat pipe 5 further obtains dispersing; if only adopt the mode of throwing the refrigerant medium between inner chamber and outer wall, do not carry out the arrangement of twining the heat pipe on the inner chamber, the heat exchange effect of doing so is not good, because the refrigerant is not mobile, and the temperature of printing ink is only depending on the refrigerant can not be fine by the quilt.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
