Description

Technical Field

[0001] The utility model relates to the field of dyeing machines, in particular to a double-cylinder housing of a dyeing color test machine. Background Art

[0002] The dyeing color test machine is the most widely used testing machine in the dyeing process. It is generally used for high-temperature dyeing and rapid testing of small samples. It has the characteristics of being able to cooperate with large-scale production, being able to take out and put in dye cups separately, and having excellent operability.

[0003] In existing dyeing machines, a large amount of heat-conducting medium needs to be loaded into the dyeing machine drum for heating and dyeing, which greatly increases the production cost of the enterprise. Secondly, when the heating element heats the heat-conducting medium, a large amount of electricity is consumed, further increasing the production cost.

[0004] The applicant in this case also provides a double-drum dyeing and color testing machine, in which the heat-conducting medium is placed in the cavity between the outer cylinder and the inner cylinder, and the dye cup is passed through the cup hole of the inner cylinder from the inside to the outside, and the dye cup extends into the cavity for heating and dyeing. Utility Model Content

[0005] The utility model aims to solve the problems of high cost of heat-conducting medium, large heating energy consumption and long heating time in the existing dyeing and color testing machine.

[0006] The utility model adopts the following technical solutions:

[0007] The double-cylinder shell of the dyeing and color testing machine includes an outer cylinder and an inner cylinder rotatably arranged in the outer cylinder. A cavity for accommodating a heat-conducting medium is formed between the outer cylinder and the inner cylinder. The radial width of the cross section of the outer cylinder passing through the central axis gradually decreases from the middle to both sides.

[0008] Furthermore, a heating device and a heat-conducting medium are provided in the outer cylinder, and the heating device heats the heat-conducting medium.

[0009] Furthermore, the shape of the inner cylinder is adapted to that of the outer cylinder.

[0010] Furthermore, the inner cylinder is provided with a cup hole for fixing the dyeing cup.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The radial width of the cross-section of the outer cylinder for holding the heat transfer medium in this utility model, passing through the central axis, gradually decreases from the center to the sides. Compared to the cylindrical drum in the prior art, this oblate spherical cavity structure, which gradually decreases from the center to the sides, can save more heat transfer medium, improve its utilization rate, and also reduce energy consumption, thus saving production costs. Furthermore, the use of direct heating solves the major problems of lag time and temperature differences caused by indirect heating. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation of the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0017] Reference Figure 1 and Figure 2 A double-cylinder housing for a dye color tester comprises a fixed outer cylinder 10 and a rotatable inner cylinder 20. The radial width of the outer cylinder 10, as measured along its central axis, tapers gradually from the center toward the sides. Specifically, the housing has an oblate spherical shape that tapers gradually from the center toward the sides. The inner cylinder 20 is shaped to match and coaxially fits with the outer cylinder 10. The outer cylinder 10 is fixedly mounted on the dye color tester, while the inner cylinder 20 is mounted within the outer cylinder 10, forming a cavity between the outer cylinder 10 and the inner cylinder 20 to accommodate a heat transfer medium.

[0018] A rotating shaft 30 is provided along the central axis of the outer cylinder 10 and the inner cylinder 20, with one end of the rotating shaft 30 connected to the top center of the right end surface. A through-hole for the rotating shaft 30 is provided on the right side wall of the outer cylinder 10, and a rotating bearing is mounted thereon. The right end surface of the inner cylinder 20 is aligned with the right side wall of the outer cylinder 10. The other end of the rotating shaft 30 passes through the through-hole on the central axis of the right side wall of the outer cylinder 10 and connects to an external rotary drive mechanism, thereby driving the inner cylinder 20 to rotate.

[0019] The inner cylinder 20 is equipped with holes for securing the dye cup. The dye cup is inserted into the dye cup mounting holes 21 on the side of the inner cylinder 20 in a radial pattern from the inside outward, extending into the cavity formed between the outer cylinder 10 and the inner cylinder 20. A heating device 50 is mounted at the bottom of the outer cylinder 10 to heat the thermal conductive medium 40, thereby heating the sample in the dye cup. The thermal conductive medium 40 is placed in the cavity to a height sufficient to soak into the dye cup and heat it, completing the dyeing process.

[0020] Specifically, the working principle of the present invention is:

[0021] A double-cylinder housing for a dyeing and color testing machine, comprising a fixed outer cylinder 10 and a rotatable inner cylinder 20, is used in dyeing and color testing machines. A heat-conducting medium 40 is loaded into the cavity between the outer cylinder 10 and the inner cylinder 20, ensuring that the heat-conducting medium 40 is high enough to soak into the portion of the dye cup within the cavity and heat the dye cup to complete the dyeing process, while not exceeding the lowest point on the side of the inner cylinder 20. The sample and dye to be dyed are loaded into the dye cup. The operator inserts the dye cup containing the sample and dye from the inside out into the cup hole 21 on the side of the inner cylinder 20 and secures it. The bottom of the dye cup can extend into the cavity and be soaked by the heat-conducting medium within the cavity.

[0022] After the dye cups are installed, the dyeing and color testing machine is started. The heating device 50 heats the heat-conducting medium to a predetermined temperature. While heating, the rotating drive mechanism drives the rotating shaft 30 to rotate the inner drum 20, thereby driving the dye cups on the inner drum 20 to rotate together for high-temperature dyeing.

[0023] Compared to a cylindrical drum, an oblate spherical drum can reduce the use of the heat conducting medium 40, thus saving costs. Furthermore, due to the reduced use of the heat conducting medium 40, the heating and cooling time of the heat conducting medium can be reduced after the dyeing operation is completed.

[0024] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
