Description

Technical Field

[0001] This utility model belongs to the field of dyeing machine technology, specifically relating to a small sample dyeing machine for precision dyeing. Background Technology

[0002] In the textile printing and dyeing industry, multi-cup dyeing machines are widely used in laboratories and small-batch production processes for dyeing process experiments and quality control of textiles. Temperature, as a key parameter affecting dyeing results, is directly related to the reproducibility of dyeing and product quality through its precise and stable control.

[0003] Currently, most multi-cup dyeing machines on the market typically employ a unified temperature control and unified drive rotation method. This means that a single temperature control system uniformly regulates the temperature within multiple dyeing cups, and a single drive system uniformly regulates the rotation time and speed of all dyeing cups. While this method is simple in structure and low in cost, it struggles to meet the varying temperature and speed requirements of different dyeing and finishing processes. For example, in the same batch of experiments, if multiple processes or dyeing tasks involving different materials need to be run simultaneously, the unified temperature and speed control cannot achieve independent and precise control of individual dyeing cups. This results in poor process adaptability, high energy consumption, and limited equipment application flexibility.

[0004] Therefore, there is an urgent need to develop a new dyeing machine that can adapt to a variety of different dyeing processes to improve the accuracy and reliability of the dyeing process. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0033] Please see Figure 1-8 This application provides a small-sample staining machine 100. The staining machine 100 includes a housing 10, a staining chamber 20, and a staining device 30.

[0034] The staining chamber 20 comprises several units, all fixedly installed within the housing 10, and each staining chamber 20 has a receiving cavity 201. It is understood that in one embodiment, the staining machine 100 contains one staining chamber 20. In another embodiment, the staining machine 100 contains two staining chambers 20. In yet another embodiment, the staining machine 100 can contain more staining chambers 20 as needed. Generally, for small-scale laboratories, the required staining machine 100 typically requires one or two staining chambers 20. Of course, to improve staining experiment efficiency and shorten staining experiment time, the more staining chambers 20 in the staining machine 100, the better. However, the size and cost of the staining machine 100 must also be considered. For larger laboratories or research institutions, it is advisable to have 8, 10, or 12 staining chambers 20 in the staining machine 100. The number of staining chambers 20 in the staining machine 100 is set as needed; no limit is placed on the number of staining chambers 20 here.

[0035] It is also understood that each dyeing box 20 is provided with a receiving cavity 201. The dyeing box 20 is fixedly installed in the dyeing machine 100. During dyeing, the dyeing device 30 or part of the structure of the dyeing device 30 can rotate in the receiving cavity 201 in the dyeing box 20 so that the dye solution can fully contact the dyeing target.

[0036] See Figure 2 The dyeing device 30 is installed inside the dyeing chamber 20, and the dyeing device 30 includes a dyeing cup mechanism 1, a driving mechanism 2, and a temperature control mechanism 3. Only one dyeing device 30 is installed in one dyeing chamber 20.

[0037] The dyeing cup mechanism 1 includes at least one dyeing cup 11 and one dyeing cup seat 12. The dyeing cup 11 is detachably fixed in the dyeing cup seat 12, which is installed in the receiving cavity 201. During dyeing, the dyeing cup seat 12 rotates in the receiving cavity 201.

[0038] It is understood that only one dyeing device 30 is installed in a dyeing box 20, and this dyeing device 30 includes only one dyeing cup mechanism 1. In one embodiment, a dyeing cup mechanism 1 includes a dyeing cup 11 and a dyeing cup holder 12, and the dyeing cup 11 is detachably installed in the dyeing cup holder 12. During dyeing, the dyeing cup holder 12 rotates in the receiving cavity 201, synchronously driving the dyeing cup 11 to rotate. During dyeing, "single cup single control" is achieved, that is, at the same time, one dyeing cup 11 performs only one dyeing process.

[0039] It is understood that, in another embodiment, a staining cup mechanism 1 includes more than one staining cup 11, such as two or three staining cups 11. Each staining cup 11 is equipped with a staining cup holder 12, and one staining cup 11 can be detachably installed in one staining cup holder 12. Alternatively, multiple staining cups 11 can be equipped with one staining cup holder 12, meaning that multiple staining cups 11 are installed in one staining cup holder 12. During staining, all staining cups 11 in the staining cup mechanism 1 of this embodiment rotate synchronously. That is, during staining, at the same time, all staining cups 11 in this staining cup mechanism 1 perform the same staining process. It should be noted that the total number of staining cups 11 in the staining cup mechanism 1 of this embodiment is generally preferably two or three. In this embodiment, providing more than one staining cup 11, and at the same time, all staining cups 11 in this staining cup mechanism 1 perform the same set of staining processes, is intended to provide one or two control groups for this staining process, so that any misoperation during the staining process can be detected in a timely manner, such as incorrect addition of reagents or incorrect dosage of reagents. In this embodiment, there is more than one dyeing cup 11, which does not affect the purpose of the dyeing machine 100 to perform multiple dyeing processes at the same time during the dyeing operation.

[0040] See Figure 2 The drive mechanism 2 is installed on the dyeing box 20, and the dyeing cup mechanism 1 is installed on the drive mechanism 2, indirectly realizing the installation of the dyeing cup mechanism 1 on the dyeing box 20. During dyeing, the dyeing cup mechanism 1 is driven to rotate by the drive mechanism 2. One drive mechanism 2 is installed on each dyeing box 20, and this drive mechanism 2 drives the dyeing cup mechanism 1 in this dyeing box 20 to rotate. It can be understood that the drive mechanism 2 on each dyeing box 20 independently drives the dyeing cup mechanism 1 in its own dyeing box 20 to rotate, realizing independent control of each dyeing cup mechanism 1, including the rotation start and stop time, rotation duration, and rotation speed of the dyeing cup mechanism 1.

[0041] A drive mechanism 2 is installed on a dyeing box 20. This drive mechanism 2 drives the dyeing cup mechanism 1 inside the dyeing box 20, realizing precise and independent control over the rotation speed, rotation duration, and rotation start-stop time of the dyeing cup mechanism 1 inside the dyeing box 20. Several dyeing boxes 20 are installed on the housing 10, and the rotation speed, duration, and start-stop time of the dyeing cup mechanism 1 in each dyeing box 20 can be controlled independently.

[0042] See Figure 5 and Figure 7 The temperature control mechanism 3 includes a temperature measuring component 31 and a temperature adjusting component 32. The temperature measuring component 31 directly acquires the real-time temperature of the dye solution in the dyeing cup 11. The temperature adjusting component 32 heats at least the dyeing cup mechanism 1.

[0043] During dyeing, the temperature measuring component 31 directly obtains the temperature of the dye solution inside the dyeing cup 11, ensuring accurate temperature acquisition and fundamentally eliminating errors in dye solution temperature measurement. The temperature regulating component 32 heats the dyeing cup mechanism 1, and combined with the accurate temperature measurement of the temperature measuring component 31, precise control of the dye solution temperature inside the dyeing cup 11 can be achieved. Furthermore, a dyeing device 30 is installed in a dyeing chamber 20, and the temperature control mechanism only measures and heats the dyeing cup mechanism 1 within this dyeing chamber 20, achieving precise control of the temperature of the dyeing cup mechanism 1 within the dyeing chamber 20.

[0044] In the dyeing machine 100, the temperature of the dyeing cup mechanism 1 in each dyeing chamber 20 can be independently controlled. Combined with the aforementioned drive mechanism 2, the rotation duration and speed of the dyeing cup mechanism 1 can be independently controlled, enabling the dyeing machine 100 to perform dyeing according to multiple dyeing processes simultaneously. This means the dyeing machine 100 can simultaneously handle multiple precise dyeing processes, improving dyeing test efficiency, shortening dyeing test time, and reducing dyeing test costs. Furthermore, the temperature, rotation speed, and rotation duration of the dyeing cup mechanism 1 in each dyeing chamber 20 can all be independently controlled, meaning the dyeing devices 30 in each dyeing chamber 20 can operate independently. This allows one or more dyeing devices 30 to be activated as needed during dyeing, avoiding the problems of empty cup rotation and empty cup heating, preventing energy waste, and promoting energy conservation and environmental protection.

[0045] See Figure 5 and Figure 6 The temperature measuring component 31 includes a temperature measuring probe 311 and a junction box 312 equipped with wiring terminals.

[0046] The temperature probe 311 is installed inside the dyeing cup 11, so that when the dyeing cup 11 rotates during dyeing, the temperature probe 311 can come into contact with the dye liquor and directly obtain the temperature of the dye liquor. The temperature of the dye liquor is obtained accurately and the measurement error of the dye liquor temperature is low.

[0047] The junction box 312 is located outside the dyeing cup 11, and its terminals are electrically connected to the temperature probe 311 and the drive mechanism 2. The junction box 312 enables the setting and installation of the terminals, and the drive mechanism 2 supplies power to the temperature probe 311 through the terminals.

[0048] See Figure 5 and Figure 8The dyeing cup 11 includes a cup body 111 and a cup lid 112 detachably connected to the cup body 111. A temperature probe 311 is mounted on the cup lid 112 and faces inwards from the cup body 111. During the dyeing process, the temperature probe 311 comes into contact with the dye liquor inside the dyeing cup 11 and obtains the real-time temperature of the dye liquor. The placement of the temperature probe 311 on the cup lid 112 and facing inwards from the cup body 111 ensures sufficient contact between the dye liquor and the temperature probe 311 during the dyeing process, allowing the temperature probe 311 to accurately obtain the dye liquor temperature and ensuring accurate measurement. Furthermore, mounting the temperature probe 311 on the cup lid 112 prevents the dyed fabric from colliding with or becoming entangled with the temperature probe 311 during the process of the fabric entering or leaving the cup body 111 or during the rotation of the dyeing cup 11, thus avoiding any impact on the normal operation of the temperature probe 311 or even its lifespan.

[0049] By installing the temperature probe 311 on the cup lid 112 and facing the inside of the cup body 111, and during the dyeing process of the dyeing cup mechanism 1, the temperature probe 311 can contact the dye solution inside the dyeing cup 11. The temperature probe 311 directly obtains the temperature of the dye solution, realizing direct and accurate measurement of the temperature of the dye solution inside the dyeing cup 11. When the temperature probe 311 measures the temperature, it directly contacts the dye solution inside the dyeing cup 11, eliminating the thermal resistance and thermal inertia effects caused by indirect temperature measurement through the cup wall of the dyeing cup 11. It can obtain the true core temperature of the dye solution in real time and accurately, that is, the real-time temperature of the dye solution, fundamentally eliminating temperature measurement errors and fundamentally improving the accuracy of temperature detection.

[0050] Temperature probe 311 is installed inside the dyeing cup 11, directly acquiring the temperature of the dye liquor. This enables real-time temperature measurement, ensuring timely control of the dye liquor temperature within the dyeing cup 11 and improving the response speed. In this design, the temperature probe 311 directly acquires the dye liquor temperature, providing precise measurement and capturing minute temperature changes. This allows for timely response and rapid issuance of temperature adjustment and control commands during dyeing, significantly shortening the temperature feedback time and resolving the issue of temperature feedback lag. Consequently, the dyeing machine 100 with this precise temperature-measuring dyeing cup mechanism 1 can more accurately track and execute the preset dyeing process temperature curve.

[0051] Please see Figure 5 The temperature measuring component 31 is installed on the inner surface of the cup lid 112. It is easy to install, easy to fix, and easy to fully contact with the dye solution during dyeing.

[0052] Please see Figure 8The junction box 312 includes a first junction box 3121 and a second junction box 3122. The first junction box 3121 is fixedly installed on the outer peripheral surface of the cup lid 112, and the second junction box 3122 is fixedly installed on the outer peripheral surface of the dye cup holder 12.

[0053] The terminal block includes a conductive contact pin 3127 fixed in the first junction box 3121 and a spring pin 3128 fixed in the second junction box 3122. After the dyeing cup 11 is placed in the dyeing cup holder 12, the first junction box 3121 and the second junction box 3122 are fixedly connected, and the conductive contact pin 3127 contacts and conducts electricity with the spring pin 3128.

[0054] The conductive contact pin 3127 is electrically connected to the temperature probe 311 via a first wire passing through the cup lid 112, and the spring pin 3128 is electrically connected to the drive mechanism 2 via a second wire.

[0055] See Figure 8 A through hole 1122 is provided on the lid 112 of the dyeing cup 11, through which a first wire passes. One end of the first wire is electrically connected to the temperature probe 311, and the other end is electrically connected to the conductive contact pin 3127. After the dyeing cup 11 is installed in the dyeing cup holder 12, the conductive contact pin 3127 and the spring pin 3128 contact and conduct electricity. The spring pin 3128 is electrically connected to the drive mechanism 2 through a second wire, thus enabling the drive mechanism 2 to supply power to the temperature probe 311. To fix the temperature probe 311, the end of the temperature probe 311 is placed in the through hole 1122 and sealed with sealant, so that only the front part of the temperature probe 311 is exposed in the dyeing cup 11 and in contact with the dye solution.

[0056] Understandably, the temperature probe 311 has a built-in signal transmitter that can send the obtained dye liquor temperature signal to the controller. Then, the controller can control the temperature control mechanism 3 to heat and adjust the temperature of the dyeing cup mechanism 1 according to the dye liquor temperature.

[0057] See Figure 8 A guide plate 1123 with a wire groove 1124 and a sealing plate 1121 are provided on the outer surface of the cup lid 112 of the dyeing cup 11. The first wire that is electrically connected to the temperature measuring probe 311 is placed in the wire groove 1124 of the guide plate 1123. Then the sealing plate 1121 is placed on the guide plate 1123, which realizes the fixation of the temperature measuring probe 311 and the first wire, ensuring the reliable installation of the temperature measuring probe 311 and extending the service life of the temperature measuring probe 311.

[0058] The temperature probe 311 is installed on the inner surface of the cup lid 112. With the arrangement of the first junction box and the second junction box 3122, if the temperature probe 311 is damaged or malfunctions, the cup lid 112 can be replaced directly. The operation is convenient and low-cost, does not require professional personnel to operate, and has good adaptability.

[0059] Furthermore, the arrangement and use of the first junction box, the second junction box 3122, the conductive contact pin 3127, and the spring pin 3128 eliminate the need for wiring operations when replacing or installing the dyeing cup 11. This facilitates the installation and removal of the dyeing cup 11 during the dyeing process, reduces the use of wires, and avoids the problem of wire tangling during dyeing in the dyeing cup mechanism 1. The conductive contact pin 3127 and the spring pin 3128 are in contact with an interference fit, ensuring a reliable electrical connection between them.

[0060] The second junction box 3122 is fixed on the dyeing cup holder 12, which facilitates the electrical connection between the spring pin 3128 and the drive mechanism 2, reduces the use of wires, and avoids the problem of wire tangling when the dyeing cup 11 assembly rotates.

[0061] See Figure 6 The second junction box 3122 is provided with a connecting spring 3123, which has a limiting hole 3124. The axis of the limiting hole 3124 is perpendicular to the axis of the dyeing cup 11, and the deformation direction of the connecting spring 3123 is along the radial direction of the dyeing cup 11. The first junction box 3121 is provided with a limiting pin 3125, the axis of which is parallel to the axis of the limiting hole 3124. After the dyeing cup 11 is placed in the dyeing cup seat 12, the limiting pin 3125 is inserted into the limiting hole 3124. By connecting the spring piece 3123, the limiting hole 3124, and the limiting pin 3125, the dyeing cup 11 is limited along the axial direction, thus achieving a fixed connection between the dyeing cup 11 and the dyeing cup seat 12. At the same time, it also achieves a fixed connection between the first junction box 3121 and the second junction box 3122, ensuring that the conductive contact pin 3127 and the spring pin 3128 are electrically connected and avoiding problems such as open circuits or poor contact between the conductive contact pin 3127 and the spring pin 3128.

[0062] See Figure 7 When the dyeing cup 11 is placed inside the dyeing cup holder 12, the first junction box 3121 moves closer to the second junction box 3122 along the axis of the dyeing cup 11. At the same time, the limiting pin 3125 pushes outward along the axis of the limiting hole 3124 to connect the spring 3123. When the limiting pin 3125 contacts the limiting hole 3124, the limiting pin 3125 enters the limiting hole 3124, realizing the connection between the limiting hole 3124 and the limiting pin 3125.

[0063] See Figure 7A rigid blocking piece 3126 is provided on the outside of the connecting spring 3123 to limit the deformation range of the connecting spring 3123 and avoid excessive deformation of the connecting spring 3123, which would result in a short service life. Both the connecting spring 3123 and the rigid blocking piece 3126 are detachably connected to the second junction box 3122.

[0064] Please see Figure 5 The drive mechanism 2 includes an electric rotary joint 21 and a drive motor 22. The electric rotary joint 21 is fixedly installed on the outer wall of the dyeing chamber 20, with one end passing through the receiving cavity 201 of the dyeing chamber 20 and fixedly connected to the outer peripheral surface of the dyeing cup holder 12. The temperature control mechanism 3 is electrically connected to the electric rotary joint 21. The drive motor 22 drives the electric rotary joint 21 to rotate around its own axis through the transmission belt 24 and pulley 23, and drives the dyeing cup holder 12 to rotate around the axis around which the electric rotary joint 21 rotates.

[0065] The use of the electric rotary connector 21 serves two purposes: firstly, it drives the dyeing cup holder 12 to rotate; secondly, it connects the spring pin 3128 to electricity. A power source, including a portable power supply or AC power, is connected to the drive motor 22. By electrically connecting the spring pin 3128 to this power source via the electric rotary connector 21, the number of wires connected to the dyeing cup holder 12 is reduced, and the problem of wire tangling is avoided.

[0066] The drive motor 22 drives the electric rotary joint 21 to rotate around its own axis via the transmission belt 24 and pulley 23, which in turn drives the dyeing cup holder 12 to rotate around the axis around which the electric rotary joint 21 rotates. That is, the drive motor 22 drives the motor pulley mounted on it to rotate, and the motor pulley drives the pulley 23 fixed to the electric rotary joint 21 to rotate via the transmission belt, thereby driving the electric rotary joint 21 to rotate, which in turn drives the dyeing cup holder 12 and the dyeing cup 11 to rotate, ensuring that the dye liquor is in full contact with the fabric being dyed during the dyeing process.

[0067] The axial direction of the electric rotary joint 21 is parallel to the radial direction of the dyeing cup 11. During dyeing, the electric rotary joint 21 drives the dyeing cup 11 to perform a flipping and rotating action, ensuring that the dye liquor is evenly stirred and that the dye liquor placed in the dyeing cup 11 is in full contact with the fabric to be dyed, thus ensuring uniform dyeing. Furthermore, the electric rotary joint 21 driving the dyeing cup 11 to perform the flipping and rotating action ensures that the dye liquor is in full contact with the temperature probe 311 placed on the cup lid 112 of the dyeing cup 11. This allows the temperature probe 311 to accurately obtain the real-time temperature of the dye liquor in the dyeing cup 11, directly obtaining the true temperature of the dye liquor. This provides feedback for the dyeing cup 11 to accurately execute the set dyeing process, realizing feedback control of the dyeing process.

[0068] The electric rotary joint 21 can be any mature product that meets the requirements of the existing technology, and there is no limitation on the model of the electric rotary joint 21.

[0069] See Figure 5 A rotating shaft connecting sleeve 25 is fixed on the outer wall of the dyeing cup 11. An electric rotating joint 21 is fixedly connected to the rotating shaft connecting sleeve 25. A heat insulation sleeve 26 is provided between the rotating shaft connecting sleeve 25 and the electric rotating joint 21.

[0070] The rotating shaft connecting sleeve 25 is fixedly connected to the outer wall of the dyeing cup 11, which can be by welding, detachable fixed connection, or other connection methods. The electric rotary joint 21 is fixedly sleeved with the rotating shaft connecting sleeve 25, so that the electric rotary joint 21 can drive the dyeing cup holder 12 to rotate through the rotating shaft connecting sleeve 25. The electric rotary joints 21 of the rotating shaft connecting sleeve 25 are fixedly connected, which can be by fastener connection, welding, or interference fit.

[0071] The heat insulation sleeve 26 is installed to isolate the heat on the dyeing cup holder 12 and prevent the heat on the dyeing cup holder 12 from being transferred to the electric rotary joint 21, which would affect the normal operation and life of the electric rotary joint 21.

[0072] The heat insulation sleeve 26 can further facilitate the cooperation between the electric rotary joint 21 and the rotary shaft connecting sleeve 25, preventing relative movement or a tendency for relative movement between the electric rotary joint 21 and the rotary shaft connecting sleeve 25, which would affect the service life of the electric rotary joint 21 or the rotary shaft connecting sleeve 25.

[0073] To ensure that the dyeing cup holder 12 and the dyeing cup 11 remain in balance during rotation and to reduce inertia, the rotating shaft connecting sleeve 25 should be positioned as close as possible to the center of gravity of the dyeing cup holder 12 along its axis.

[0074] See Figure 7 The temperature control component 32 includes a heating element 321, which includes a heating ring 3211. The heating ring 3211 is sleeved on the outer wall of the dyeing cup holder 12 to heat the dyeing cup holder 12. The heat is then transferred to the dyeing cup 11 through the dyeing cup holder 12, thereby heating the dye solution inside the dyeing cup 11 and enabling dyeing according to the set dyeing process. The inner diameter of the heating ring 3211 is adapted to the outer diameter of the dyeing cup holder 12, allowing direct contact between the heating ring 3211 and the outer wall of the dyeing cup holder 12, improving heat transfer efficiency and reducing heat loss. The dyeing cup holder 12 is sleeved on the outside of the dyeing cup 11, and its inner diameter is adapted to the outer diameter of the dyeing cup 11, maximizing the transfer of heat from the dyeing cup holder 12 to the dyeing cup 11, resulting in rapid heating of the dye solution inside the dyeing cup 11 and minimizing heat loss during cooling.

[0075] The matching of the inner and outer diameters of the heating ring 3211, the dyeing cup holder 12, and the dyeing cup 11 enables a rapid response to the temperature control of the dye solution inside the dyeing cup 11, improving dyeing efficiency and enabling more precise execution of the set dyeing process.

[0076] A ventilation collar 3212 is fitted over the heating ring 3211. The ventilation collar 3212 includes a cylindrical sleeve body and ventilation holes arranged on the cylindrical sleeve body. The cylindrical sleeve cup body 111 is fitted over the back of the heating ring 3211 and detachably fixed to the dyeing cup holder 12. The ventilation collar 3212 serves two purposes: firstly, it protects the heating ring 3211 from collisions with external structures; secondly, it covers the heating ring 3211 within the ventilation collar 3212, preventing burns caused by the operator touching the heating ring 3211. In this embodiment, the ventilation holes enable the ventilation collar 3212 to provide ventilation, facilitating the cooling and temperature regulation of the dyeing cup 11 and allowing for rapid and strong cooling of the dyeing cup 11 by the fan.

[0077] The height of the ventilated collar 3212 is approximately half the height of the dye cup holder 12, and the ventilated collar 3212 is detachably and fixedly connected to the dye cup holder 12 by bolts.

[0078] The heating ring 3211 is located inside the ventilated collar 3212, and the height of the heating ring 3211 is adapted to the height of the ventilated collar 3212 to ensure the heating area of ​​the dyeing cup holder 12.

[0079] See Figure 3 and Figure 4 The temperature control component 32 also includes a cooling component 322, which includes a fan, an air inlet, an air outlet, an air inlet channel 3221, and an air outlet channel 3222. Both the air inlet and the air outlet are located on the dyeing chamber 20, and a one-way valve is also installed on the air outlet. One end of the air inlet channel 3221 is connected to the air inlet, and the other end is connected to the air outlet of the fan; one end of the air outlet channel 3222 is connected to the air outlet, and the other end is located on the casing 10. The fan is mounted on the casing 10.

[0080] The opening of the dyeing box 20 faces the front side of the housing 10. A dyeing box cover 202 is installed on the front side of the housing 10. During dyeing, the dyeing box cover 202 seals the opening of the dyeing box 20, that is, seals the accommodating cavity 201. The bottom surface of the dyeing box 20 opposite to the opening faces the rear side of the housing 10. The air inlet and air outlet are both located on the bottom surface of the dyeing box 20 opposite to the opening. The end of the exhaust channel 3222 away from the exhaust outlet is located on the rear side of the housing 10.

[0081] The system includes a fan, air inlet, air outlet, air inlet channel 3221, and air outlet channel 3222, enabling the dyeing cup 11 to be cooled when needed, adapting to different dyeing process requirements. The fan allows for rapid cooling of the dyeing cup 11 when it is at a high temperature, shortening the dyeing process time and improving dyeing efficiency.

[0082] A control system is installed on the housing 10. The control system is connected to the drive mechanism 2 and the temperature control mechanism 3 by signal, and further connected to the temperature probe 311, the electric rotary joint 21, the heating component 321, and the cooling component 322 by signal. The control system includes a controller and a human-machine interface 40. The operator can set and adjust the dyeing process parameters on the human-machine interface 40. Then, the controller controls the electric rotary joint 21, the heating component 321, and the cooling component 322 to work according to the set parameters. The dye liquor temperature obtained by the temperature probe 311 is sent to the controller through the signal transmitter integrated in the temperature probe 311. The controller performs feedback control on the electric rotary joint 21, the heating component 321, and the cooling component 322 based on the obtained dye liquor temperature, executes the dyeing program, and accurately executes the dyeing process.

[0083] The controller uses an existing controller, such as a PLC or IPC. An electrical box 50 is installed on the housing 10, and the controller is installed inside the electrical box 50.
