Description

Technical Field

[0001] The invention relates to the technical field of dyeing, in particular to a dyeing color testing machine. Background Art

[0002] The dyeing color tester is the most widely used testing machine in the dyeing process. It is generally used for high-temperature dyeing and rapid sample testing. It has the characteristics of being able to cooperate with large-scale production, the ability to individually remove and place dye cups, and excellent operability. The existing dyeing color tester includes a housing, a rotating disk located within the housing, and several dye cups. The rotating disk is connected to a transmission mechanism, which includes a fixed shaft and a rotating shaft sleeved on the fixed shaft. The rotating disk is filled with heat transfer oil, and the heat transfer oil is provided with a heating element fixedly connected to the fixed shaft. The rotating disk also includes several dye cup sleeves fixed to the rotating disk and can be immersed in a liquid heat transfer medium. The opening of each dye cup sleeve is exposed outside the rotating disk, and each dye cup is fixedly mounted in a corresponding dye cup sleeve in a removable manner.

[0003] The boxes for loading heat-conducting media in the above-mentioned dyeing and color testing machines are mostly rectangular boxes. A large amount of heat-conducting oil is consumed as the heat-conducting medium during dyeing, which will inevitably greatly increase the production cost of the enterprise. Moreover, a large amount of electricity is consumed when the heating element heats the heat-conducting oil, which further increases the production cost of the enterprise. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the dyeing and color testing machine consumes a lot of energy to heat the heat-conducting medium and has a slow heating rate, which leads to high production costs.

[0005] The utility model adopts the following technical solutions:

[0006] A dyeing and color testing machine includes an outer cylinder, a rotating frame rotatably arranged in the outer cylinder, a plurality of dye cups and a heating device. The radial width of the cross section of the outer cylinder passing through the central axis gradually decreases from the middle to both sides. The outer cylinder is filled with a heat-conducting medium. The dye cups are mounted on the rotating frame. The heating device heats the heat-conducting medium, and the heat-conducting medium directly heats the dye cups.

[0007] Furthermore, the outer cylinder is provided with an operation hole for mounting the dye cup on the rotating frame, and the operation hole is detachably provided with a cover plate for sealing the operation hole.

[0008] 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:

[0009] The radial width of the cross section of the outer cylinder for containing the heat-conducting medium passing through the central axis of the utility model gradually decreases from the middle to both sides. Compared with the rectangular box of the existing dyeing and color testing machine, the oblate spherical cavity structure that gradually decreases from the middle to both sides can save more heat-conducting medium, improve the utilization rate of the heat-conducting medium, and also reduce the consumption of electric energy, saving production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The numbers in the figure are: outer cylinder 10, cover plate 11, rotating frame 20, fixing member 21, dye cup 30, heating device 40, heat conducting medium 50, rotating shaft 60. DETAILED DESCRIPTION

[0013] The specific implementation of the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0014] Reference Figure 1 and Figure 2 A dyeing and color testing machine comprises a main body formed by an outer cylinder 10. The radial width of the outer cylinder 10, as measured along its central axis, tapers gradually from the center toward the sides. Specifically, the outer cylinder 10 has an oblate spherical cavity structure that tapers gradually from the center toward the sides. The top of the outer cylinder 10 defines an access hole for mounting a dye cup 30 on a rotating frame 20. A removable cover plate 11 seals the access hole, ensuring a sealed environment within the outer cylinder 10 during operation.

[0015] Inside the outer drum 10, a rotating frame 20 is located. The rotating frame 20 is composed of two symmetrically arranged circular discs. A rotating shaft 60 is positioned along the central axis of the outer drum 10 and passes through the center of the rotating frame 20 and the sidewalls of the outer drum 10. One end of the rotating shaft 60, which passes through the sidewall of the outer drum 10, connects to an external rotary drive mechanism, thereby driving the rotating frame 20. Fixing members 21 for securing the dye cups 30 are symmetrically positioned on the circular discs of the rotating frame 20.

[0016] A heating device 40 is installed at the bottom of the outer cylinder 10 to heat a heat-conducting medium 50, thereby heating the sample in the dye cup 30. The heat-conducting medium 50 is placed inside the outer cylinder 10, ensuring that it is high enough to soak into the dye cup 30 and heat it, completing the dyeing process. Preferably, thermal oil can be used as the heat-conducting medium 50.

[0017] Specifically, the working principle of the present invention is:

[0018] Open the cover 11 on top of the outer drum 10 and add an appropriate amount of heat-conducting medium 50 to the inner portion of the outer drum 10, ensuring that the heat-conducting medium 50 is high enough to soak into and heat the dye cup 30, thus completing the dyeing process. Place the sample and dye into the dye cup 30, and the staff secure the dye cup 30 containing the sample and dye to the fixture 21 on the rotating frame 20.

[0019] After the dye cup 30 is installed, the cover plate 11 is closed and the dyeing machine is started. The heating device 40 heats the heat-conducting medium 50 to a predetermined temperature. While heating, the rotating drive mechanism drives the rotating shaft 60 to rotate the rotating frame 20, thereby driving the dye cup 30 on the rotating frame 20 to rotate together for high-temperature dyeing.

[0020] Compared to the existing rectangular box, the oblate spherical cylinder structure can reduce the use of the heat conducting medium 50, saving costs. At the same time, due to the reduced use of the heat conducting medium 50, the time for heating and cooling the heat conducting medium 50 after the dyeing operation is completed will also be reduced.

[0021] 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.
