Description

Technical Field

[0001] The invention relates to the technical field of dyeing, in particular to a double-drum dyeing color tester. Background Art

[0002] The dyeing color tester is the most widely used tester 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, being able to take and place dye cups individually, and having excellent operability. The existing dyeing color tester includes a box body, a rotating disk arranged in the box body, and several dye cups. The rotating disk is connected to a transmission mechanism. The transmission mechanism includes a fixed shaft and a rotating shaft sleeved on the fixed shaft. The rotating disk is filled with heat transfer oil. A heating element is arranged in the heat transfer oil. The heating element is fixedly connected to the fixed shaft. It also includes several dye cup sleeves fixed on 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. Each dye cup is fixedly arranged in the corresponding dye cup sleeve in a movable and removable manner.

[0003] The above-mentioned dyeing and color testing machine uses direct heating of the dye cup for dyeing, which consumes a large amount of heat transfer oil as a heat transfer medium, which will inevitably greatly increase the production cost of the enterprise. Moreover, the heating element needs to consume a large amount of electricity when heating the heat transfer oil, which further increases the production cost of the enterprise. For example, a new type of small sample dyeing machine disclosed in patent number ZL200910112150.0 and a circulating air-heated laboratory color testing machine disclosed in publication number CN 103757848A both use indirect heating, with a slow heating rate, and it is difficult to keep the temperature fixed, which affects the high-temperature dyeing effect. Regardless of the type of dyeing and color testing machine, if the dye cup is not set firmly, it will fall into the box during operation, thereby damaging the equipment and jamming the host machine, increasing the maintenance cost of the equipment. Summary of the invention

[0004] The present invention provides a double-drum dyeing color tester, the main purpose of which is to solve the problem that the existing dyeing color tester using direct heating has high energy consumption of heat-conducting medium and the dyeing color tester using indirect heating has slow heating rate, thus leading to high enterprise costs.

[0005] The present invention adopts the following technical solution: A double-drum dyeing color tester comprises an outer drum, an inner drum rotatably arranged in the outer drum, a plurality of dye cups and a heating device, a cavity for accommodating a heat-conducting medium is formed between the outer drum and the inner drum, a plurality of unsealed dye cup holes are arranged on the side of the inner drum, the dye cups are inserted into the cup holes from the inside to the outside of the inner drum, and the dye cups extend into the cavity, the heating device heats the heat-conducting medium, and the heat-conducting medium directly heats the dye cups.

[0006] Furthermore, the width of the cross section of the outer cylinder passing through the central axis in the radial direction gradually decreases from the middle to both sides, which can save heat transfer medium.

[0007] Furthermore, the end surface of the inner cylinder is matched with the outer cylinder.

[0008] Furthermore, a cup holder for fixing the dyeing cup is provided on the cup hole.

[0009] Furthermore, a barrier member is provided at the opening of the cup holder for preventing the heating medium from leaking out and for allowing the dye cup to pass through.

[0010] Furthermore, the barrier is made of an elastic material with a cutout.

[0011] Furthermore, a plurality of paddles for stirring the heating medium in the cavity are provided on the outer side of the inner cylinder to increase the heat conduction range.

[0012] Furthermore, the length of the pick is greater than the length of the portion of the dye cup located in the cavity.

[0013] Furthermore, the inner cylinder is provided with an operating hole for installing the dye cup.

[0014] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following advantages: 1. The present invention has a double-tube structure of an outer tube and an inner tube, and the heat-conducting medium is placed in the cavity between the outer tube and the inner tube, which reduces the use of the heat-conducting medium. At the same time, the placement of the dye cup on the inner tube is from the inside to the outside, which is different from the placement from the outside to the inside in the prior art. After the dye cup falls off, it will not cause the machine to get stuck or damage the equipment, thus reducing the maintenance cost of the enterprise.

[0015] 2. When the present invention is working, the dye solution and the sample to be dyed are placed in the dye cup, and the dye cup is inserted from the inside to the outside into the cup hole on the inner cylinder. The dye cup is heated by direct heating, and the heating rate is fast and the temperature difference fluctuation is small, which improves the effect of high-temperature dyeing and greatly saves the production time of the enterprise.

[0016] 3. The inner cylinder of the present invention is provided with a plurality of paddles, which can paddle the heat-conducting medium between the outer cylinder and the inner cylinder during heating, so that the heat-conducting medium is heated evenly, which can reduce the usage of the heat-conducting medium and thus reduce the production cost.

[0023] The specific implementation of the embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 3 A double-cylinder dyeing color tester, comprising a fixed outer cylinder 10 and a rotatable inner cylinder 20. The outer cylinder 10 and the inner cylinder 20 are coaxially arranged, and the inner cylinder 20 is installed inside the outer cylinder 10. A cavity for accommodating a heat-conducting medium is formed between the outer cylinder 10 and the inner cylinder 20. The outer cylinder 10 is fixed by an external bracket or fixed in an external box. The radial width of the cross section of the outer cylinder 10 passing through the central axis decreases from the middle to both sides. Compared with a cylindrical drum, the volume of the heat-conducting medium in the cavity is reduced, the utilization rate of the heat-conducting medium is increased, the cost is saved, and the heating time is shortened. A layer of stainless steel heat insulation is wrapped on the outer surface of the outer cylinder 10.

[0025] The dye cup is placed in a manner that it penetrates the dye cup installation hole 23 on the side of the inner cylinder 20 in a divergent manner from the inside to the outside of the inner cylinder 20 and extends to the cavity formed between the outer cylinder 10 and the inner cylinder 20. Heat transfer oil or other heat transfer medium is placed in the cavity so that the height of the heat transfer medium can soak into the dye cup and heat the dye cup, and does not exceed the lowest position of the side of the inner cylinder 20. A heating device 50 is installed at the bottom of the outer cylinder 10 to heat the heat transfer medium, thereby heating the sample in the dye cup.

[0026] Reference Figure 2 and Figure 3The middle part of the inner cylinder 20 is a hollow cylinder, and the end faces on both sides are hemispherical end faces that match the outer cylinder 10. An operation hole 22 is provided on the left end face, through which the dye cup can be placed inside the inner cylinder 20 and inserted into the dye cup mounting hole 23. A rotating shaft 30 is provided on the central axis of the outer cylinder 10 and the inner cylinder 20, and one end of the rotating shaft 30 is connected to the top center of the right end face. A through hole for the rotating shaft 30 to pass through is provided on the right side wall inside the outer cylinder 10, and a rotating bearing is installed. The right end face of the inner cylinder 20 fits the right side wall inside the outer cylinder 10, and 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 is connected to the external rotating drive mechanism, thereby driving the inner cylinder 20 to rotate.

[0027] A plurality of dye cup mounting holes 23 for mounting dye cups are evenly arranged on the side wall of the middle part of the inner cylinder 20, wherein a paddle 21 is arranged between each two adjacent dye cup mounting holes 23 in a row, the length of the paddle 21 is greater than the length of the portion of the dye cup located in the cavity, and the paddle 21 is arranged at an angle to reduce the resistance encountered by the paddle 21 when the inner cylinder 20 rotates when the heat conducting medium is moved. The paddle 21 can move the heat conducting medium placed in the cavity between the outer cylinder 10 and the inner cylinder 20 when the inner cylinder 20 rotates, so that the dye cup is heated evenly, and the effect of high temperature dyeing of the sample is improved. At the same time, since the paddle 21 can move the heat conducting medium, the heat conducting range is increased, and the use of the heat conducting medium is also saved.

[0028] Reference Figure 3 and Figure 4 Each dye cup mounting hole 23 on the inner cylinder 20 is fixed with a corresponding cup holder 40 for fixing the dye cup by bolts. A through hole is provided in the center of the cup holder 40 for inserting the dye cup. The dye cup is inserted into the through hole in the center of the cup holder 40 with a specific gap and the dye cup is rotated so that the dye cup can be fixed by the clamping groove 41.

[0029] At the same time, refer to Figure 5 A cross-shaped barrier 42 is provided at the through hole in the center of the cup holder 40. The barrier 42 is made of elastic material and is used to prevent the heat-conducting medium from leaking into the inner tube 20, thereby reducing the cleaning cost. The barrier 42 can be opened when the dye cup is inserted into the cup holder 40. Since it is made of elastic material, it can be automatically closed after the dye cup is pulled out of the cup holder 40, thereby effectively preventing the heat-conducting medium from leaking out.

[0030] Specifically, when using the dyeing color tester, The sample and dye to be dyed are loaded into the dye cup, and the operator inserts the dye cup containing the sample and dye from the inside to the outside through the operation hole 22 into the cup holder 40 installed on the dye cup mounting hole 23 on the side of the inner cylinder 20. At this time, the blocking member 42 on the through hole of the cup holder 40 automatically opens after receiving pressure, and fits tightly with the side wall of the dye cup. After insertion, the dye cup is rotated so that the dye cup can be clamped and fixed by the clamping groove 41.

[0031] After the dye cup is installed, the dyeing tester is started, and 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 drive the inner cylinder 20 to rotate, thereby driving the dye cup on the inner cylinder 20 to rotate together for high-temperature dyeing. The paddle 21 on the side of the inner cylinder 20 can pry the heat-conducting medium while the inner cylinder rotates, so that the heat conduction range is larger and the heating is more uniform.

[0032] Due to the reduced use of heat-conducting medium, the cooling time of the heat-conducting medium is also reduced after the dyeing operation is completed. After the cooling is completed, the dye cup can be taken out of the cup holder 40 by rotating. At this time, the pressure on the barrier 42 disappears, and the barrier 42 is turned into a closed state, completing the dyeing operation.

[0033] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. 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.
