Description

Technical Field

[0001] This utility model belongs to the field of dyeing machine technology, specifically relating to a dyeing device and dyeing machine with precise temperature control. Background Technology

[0002] The sample dyeing machine is an important piece of equipment in the dyeing and finishing industry for color matching, sampling, and process verification. Its basic working principle involves a motor-driven rotating frame inside a heated cylinder. Multiple dyeing cups, each holding a fabric sample and dye liquor, are mounted on this frame. During operation, the rotating frame drives all the dyeing cups to rotate together, ensuring thorough mixing of the dye liquor and fabric sample, thus achieving the dyeing purpose.

[0003] However, existing dyeing facilities still have significant limitations in temperature control. First, some equipment is only equipped with heating devices, which cannot achieve rapid cooling and flexible temperature adjustment, making it difficult to adapt to the process requirements of multi-stage heating and cooling. Even if some equipment integrates cooling functions, its structure is often complex, its operational reliability is low, and its energy consumption is high. Second, most existing dyeing equipment uses a whole-body heating or cooling method, which cannot independently and accurately control the temperature of each dyeing cup. Therefore, it is difficult to implement differentiated processes within the same batch, limiting sampling efficiency and accuracy.

[0004] Furthermore, current equipment has shortcomings in temperature detection and monitoring. A common method for measuring temperature in dyeing facilities is to indirectly measure the temperature of the dyeing cup holder or the outer wall of the dyeing cup to estimate the internal dye liquor temperature. This method is greatly affected by the environment and the heat transfer characteristics of the materials, and cannot accurately reflect the actual temperature of the dye liquor in real time, leading to problems such as poor process repeatability and inconsistent dyeing results.

[0014] As an optional implementation, the temperature control component further includes a cooling component, which is electrically connected to the control component, and the control component controls the cooling state of the cooling component based on the real-time temperature of the dye liquor obtained by the temperature probe.

[0033] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0034] Please refer to Figures 1-2. This application provides a dyeing apparatus with precise temperature control.

[0035] A precise temperature-controlled dyeing apparatus includes a dyeing cup 1, a dyeing cup holder 2, and a temperature regulating mechanism. The dyeing cup 1 is fixed inside the dyeing cup holder 2, and the outer wall of the dyeing cup 1 is in contact with the inner wall of the dyeing cup holder 2. The temperature regulating mechanism is used to regulate the temperature of the dyeing cup 1 so that the dye solution inside the dyeing cup 1 reaches the required temperature, thereby achieving dyeing.

[0036] The temperature control mechanism includes a temperature measuring component 3, a temperature control component, and a control component.

[0037] The temperature measuring component 3 includes a temperature measuring probe 31, which is disposed inside the dyeing cup 1. The temperature measuring probe 31 is in contact with the dye solution in the dyeing cup 1 at least when the dyeing cup 1 is performing dyeing work, so as to obtain the real-time temperature of the dye solution.

[0038] The temperature control assembly includes a heating element 32, which is disposed in close contact with the outer wall of the dyeing cup holder 2.

[0039] The control component is electrically connected to the temperature measuring component 3, and the control component controls the heating state of the heating component 32 based on the real-time temperature of the dye liquor obtained by the temperature measuring probe 31.

[0040] In traditional dyeing facilities, the temperature of the dyeing solution inside the dyeing cup 1 is typically estimated indirectly by measuring the temperature of the outer wall of the dyeing cup 1 or the outer wall of the dyeing cup holder 2. However, due to thermal resistance and thermal inertia between the cup wall and the dye solution, the detected temperature deviates significantly from the actual temperature of the dye solution, making accurate temperature measurement impossible. In the above embodiment, however, the temperature probe 31 is placed inside the dyeing cup 1. During temperature measurement, the probe 31 directly acquires the temperature of the dye solution, achieving direct and accurate measurement of the dye solution temperature inside the dyeing cup 1. Since the probe 31 directly contacts the dye solution inside the dyeing cup 1, it eliminates the effects of thermal resistance and thermal inertia caused by indirect temperature measurement through the cup wall. This allows for real-time and accurate acquisition of the true core temperature of the dye solution, i.e., the real-time temperature of the dye solution, fundamentally eliminating temperature measurement errors and significantly improving the accuracy of temperature detection.

[0041] In this embodiment, the temperature probe 31 is placed inside the dyeing cup 1. During temperature measurement, the temperature probe 31 directly acquires the temperature of the dye solution, improving the real-time performance and response speed of the dye solution temperature control during the dyeing process. Because the real-time temperature of the dye solution can be directly acquired in this embodiment, the temperature probe 31 can immediately sense subtle changes in the dye solution temperature and acquire the real-time temperature during dyeing. Combined with the heating component 32 located close to the outer wall of the dyeing cup holder 2 and the control component electrically connected to the heating component 32, this dyeing assembly can quickly issue commands for adjusting and controlling the dye solution temperature during the dyeing process and immediately and accurately execute temperature control and adjustment operations. This greatly avoids the lag in dye solution temperature feedback and enables more precise tracking and execution of the dyeing process.

[0042] In this embodiment, the temperature probe 31 is disposed inside the dyeing cup 1. This arrangement means that in a dyeing mechanism with multiple dyeing cups 1, each or every dyeing cup 1 will have a temperature probe 31. Each temperature probe 31 only acquires the temperature of the dye solution within its own dyeing cup 1, providing conditions for high-precision and differentiated temperature control of the dye solution within the dyeing cup 1. In this embodiment, the temperature probe 31 is directly disposed inside the dyeing cup 1 and directly acquires the temperature of the dye solution within a single dyeing cup 1. Combined with a heating component 32 disposed close to the outer wall of the dyeing cup base 2 and a control component electrically connected to the heating component 32, the control component controls the heating state of the heating component 32 based on the real-time temperature of the dye solution acquired by the temperature probe 31. This allows the dyeing mechanism to independently and precisely adjust the temperature of each dyeing cup during dyeing operations, thereby enabling the dyeing machine with this dyeing mechanism to support personalized dyeing and finishing processes with multiple dyeing cups 1 operating at different temperatures simultaneously. In this embodiment, the temperature probe 31, the heating component 32, and the control component form a closed-loop temperature control feedback system, which realizes automatic temperature measurement and control, and the temperature control is accurate and fast, eliminating the temperature control delay.

[0043] In this embodiment, the temperature probe 31 is placed inside the dyeing cup 1. During temperature measurement, the temperature probe 31 directly obtains the temperature of the dye solution, which helps to save energy and reduce consumption. The temperature probe 31 directly obtains the temperature of the dye solution inside the dyeing cup 1. During the dyeing process, the control component controls the heating state of the heating component 32 on the dyeing cup holder 2, i.e., the heating state of the dye solution, based on the real-time temperature of the dye solution obtained by the temperature probe 31. This enables precise control of the dye solution temperature, avoiding unnecessary overheating or cooling of the dyeing cup 1 or the dye solution, reducing energy waste and avoiding time waste.

[0044] In this embodiment, the temperature probe 31 is disposed inside the dyeing cup 1. The temperature probe 31 is located inside the dyeing cup 1 and, at least during the dyeing process, can contact the dye solution inside the dyeing cup 1, directly obtaining the temperature of the dye solution. That is, depending on the needs or design, the temperature probe 31 can be placed at any position inside the dyeing cup 1, such as on the lid 12, the bottom of the cup, or the inner wall of the dyeing cup 1, or at any position inside the dyeing cup 1 that can contact the dye solution, as long as it ensures that the temperature probe 31 can contact the dye solution during the dyeing process. During the dyeing process, the temperature probe 31 can be in contact with the dye solution. This can be achieved by the temperature probe 31 being in constant contact with the dye solution, or by the temperature probe 31 maintaining periodic or regular contact with the dye solution, or by the temperature probe 31 contacting the dye solution when the dyeing cup 1 is in one or more states, ensuring that the temperature of the dye solution used for dyeing inside the dyeing cup 1 can be obtained during the dyeing process.

[0045] According to conventional dyeing processes, the dyeing cup 1 rotates during the dyeing process. To ensure sufficient contact between the dye solution and the target material, and to ensure thorough and uniform mixing of the dye solution in all locations within the dyeing cup 1, resulting in uniform dyeing, the dyeing cup 1 is typically rotated in an inclined position, i.e., the dyeing cup 1 is placed at an angle, with its rotation axis forming an angle with its own axis; or the dyeing cup 1 rotates inverted manner, i.e., its mouth and bottom rotate back and forth, in which case its rotation axis is perpendicular to its own axis; or the dyeing cup 1 can also be rotated in other ways; or the dyeing cup 1 can be in a reciprocating motion, such as reciprocating oscillation or rotation. The position of the temperature probe 31 within the dyeing cup 1 is chosen to ensure that it can contact the dye solution during the rotation or oscillation process, allowing direct acquisition of the dye solution temperature. In other words, the rotation method of the dyeing cup 1 should be selected to ensure that the dye solution can contact the temperature probe 31 during the rotation of the dyeing cup 1.

[0046] Of course, after the temperature probe 31 is placed inside the dyeing cup 1, the dye solution can contact the temperature probe 31 regardless of whether the dyeing cup 1 is rotated or not, and the temperature probe 31 can directly obtain the temperature of the dye solution inside the dyeing cup 1.

[0047] In this embodiment, the dyeing cup 1 is fixed inside the dyeing cup holder 2, and the outer wall of the dyeing cup 1 is in contact with the inner wall of the dyeing cup holder 2. The heating element 32 of the temperature control component is also closely attached to the outer wall of the dyeing cup holder 2, allowing the heat generated by the heating element 32 to be transferred to the dyeing cup 1 through the dyeing cup holder 2 to the maximum extent, thus improving heating efficiency and increasing thermal energy utilization. In this embodiment, one heating element 32 heats only one dyeing cup holder 2, that is, only one dyeing cup 1. Combined with the temperature probe 31 and control component installed inside the dyeing cup 1, precise heating and temperature control of a single dyeing cup 1 is achieved, avoiding unnecessary heating or temperature control of other components on the dyeing cup 1 or the dye solution, and also avoiding the problem of heating an empty cup, thus reducing energy waste.

[0048] Furthermore, in this embodiment, the dyeing cup 1 is fixed inside the dyeing cup holder 2, and the outer wall of the dyeing cup 1 is in contact with the inner wall of the dyeing cup holder 2. The heating component 32 of the temperature control assembly is set close to the outer wall of the dyeing cup holder 2, and the temperature probe 31 is set inside the dyeing cup 1. During the dyeing process, the temperature probe 31 can directly contact the dye liquor, realizing "one temperature measurement and one temperature control per cup". This allows the dyeing mechanism to independently and accurately adjust the temperature of each dyeing cup during the dyeing process, thereby enabling the dyeing machine with this dyeing mechanism to support multiple dyeing cups 1 to run at different temperatures simultaneously for personalized dyeing and finishing processes, adapting to different dyeing processes and needs.

[0049] In some embodiments, the dyeing cup 1 includes a cup lid 12 and a cup body 11, the cup lid 12 and the cup body 11 are detachably and sealed together, and the temperature probe 31 is fixed on the inner surface of the cup lid 12.

[0050] In this embodiment, the cup lid 12 and the cup body 11 are detachably and sealed to ensure that the dyeing cup 1 is sealed during the dyeing process, so as to avoid the dyeing solution from overflowing, affecting the dyeing work or damaging the dyeing mechanism.

[0051] In this embodiment, the temperature probe 31 is fixed on the inner surface of the cup lid 12. The temperature probe 31 is mounted on the cup lid 12. During the dyeing process, the dyeing cup 1 rotates, and the temperature probe 31 comes into contact with the dye solution inside the dyeing cup 1, acquiring the temperature of the dye solution. This allows the temperature probe 31 to obtain the real-time, accurate, and precise temperature of the dye solution.

[0052] In this embodiment, the inner surface space of the cup lid 12 is relatively large, and the installation position is relatively convenient, which facilitates the installation of the temperature probe 31. That is, the temperature probe 31 is fixedly installed on the inner surface of the cup lid 12, which simplifies the installation operation of the temperature probe 31, makes the installation of the temperature probe 31 reliable, ensures the normal operation of the temperature probe 31, and extends the service life of the temperature probe 31.

[0053] In this embodiment, the cup lid 12 and the cup body 11 are detachably and sealed together. The temperature probe 31 is fixed on the inner surface of the cup lid 12, facilitating the setting, installation, and maintenance of the temperature probe 31. Installing the temperature probe 31 on the inner surface of the cup lid 12 ensures that when the object to be dyed is placed inside the cup body 11, or when it is removed from the body, the object will not come into contact with, bump, scratch, or affect the temperature probe 31. This reduces the impact on the temperature probe 31, ensures its performance, and extends its service life. Furthermore, by installing the temperature probe 31 on the cup lid 12, when replacing the temperature probe 31, the cup lid 12 can be replaced directly. Alternatively, if the temperature probe 31 fails, a cup lid 12 with a fully functional temperature probe 31 can be directly replaced to continue the dyeing process without needing to replace the cup body 11, thus reducing material costs and, more importantly, time and operational costs associated with maintenance.

[0054] Of course, in some embodiments, the temperature probe 31 can also be fixed on the inner wall of the cup lid 12, such as the inner side wall of the cup lid 12. The installation position of the temperature probe 31 only needs to ensure that the temperature probe 31 can be in full contact with the dye solution during dyeing to obtain the temperature of the dye solution.

[0055] In some embodiments, the inner diameter of the dyeing cup holder 2 is adapted to the outer diameter of the cup body 11, and the depth of the dyeing cup holder 2 is adapted to the height of the cup body 11. After the dyeing cup 1 is fixed inside the dyeing cup holder 2, the cup lid 12 is located outside the dyeing cup holder 2.

[0056] In this embodiment, the inner diameter of the dyeing cup holder 2 is adapted to the outer diameter of the cup body 11, and the depth of the dyeing cup holder 2 is adapted to the height of the cup body 11. This facilitates the dyeing cup holder 2 to limit and fix the dyeing cup 1 in the radial direction, simplifies the installation structure required for the installation of the dyeing cup 1, reduces the cost of the dyeing cup 1 and the dyeing cup holder 2, and simplifies the installation operation process of the dyeing cup 1.

[0057] In this embodiment, the inner diameter of the dyeing cup holder 2 is adapted to the outer diameter of the cup body 11. That is, after the dyeing cup 1 is placed in the dyeing cup holder 2, the outer surface of the dyeing cup 1 is in contact with the inner surface of the dyeing cup holder 2. When the heating component 32 is set close to the outer wall of the dyeing cup holder 2 and heats the outer wall of the dyeing cup holder 2, the heat on the dyeing cup holder 2 can be transferred to the dyeing cup 1 through the dyeing cup holder 2 to the maximum extent, so as to ensure that the dyeing cup 1 is heated evenly, improve the heating efficiency, and improve the heat energy utilization rate.

[0058] In some embodiments, the heating component 32 includes a heating ring, which is clamped on the outer peripheral surface of the dyeing cup holder 2, and the inner wall of the heating ring is in contact with the outer peripheral surface of the dyeing cup holder 2.

[0059] In this embodiment, the heating component 32 adopts a heating ring, which facilitates installation and increases the contact area with the outer wall of the dyeing cup holder 2, thereby improving the heating efficiency of the dyeing cup 1 and accelerating the heating rate of the dyeing cup 1. Furthermore, the heating component 32 adopts a heating ring, which, while ensuring the contact area with the outer wall of the dyeing cup holder 2, has a small size and light weight, which can effectively reduce the volume of the dyeing mechanism and reduce the inertia of the dyeing cup 1 during rotation, thus reducing the requirements on the electric rotary joint 41 that drives the rotation of the dyeing cup 1.

[0060] In some embodiments, the heating ring is positioned close to the bottom of the dyeing cup holder 2, and the position of the heating ring is far from the cup lid 12 of the dyeing cup 1. This avoids excessive heat being transferred from the cup body 11 of the dyeing cup 1 to the cup lid 12, thus avoiding any impact on the temperature probe 31 mounted on the cup lid 12. On the one hand, this avoids affecting the temperature accuracy of the temperature probe 31, and on the other hand, it avoids affecting the performance of the temperature probe 31 itself and reducing its service life.

[0061] In some embodiments, a ventilation collar 33 is fitted around the heating ring. The ventilation collar 33 includes a cylindrical sleeve body and ventilation holes arranged on the cylindrical sleeve body. The cylindrical sleeve cup body 11 is fitted onto the back of the heating ring and detachably fixed to the dyeing cup seat 2. The ventilation collar 33 serves two purposes: firstly, it protects the heating ring from collisions with external structures; secondly, it covers the heating ring within the ventilation collar 33, preventing burns caused by the operator touching the heating ring. In this embodiment, the ventilation holes enable the ventilation collar 33 to provide ventilation, facilitating the cooling and temperature regulation of the dyeing cup 1 and allowing for rapid and strong cooling of the dyeing cup 1 by the fan.

[0062] The height of the ventilated collar 33 is approximately half the height of the dye cup holder 2, and the ventilated collar 33 is detachably and fixedly connected to the dye cup holder 2 by bolts 331.

[0063] The heating ring is located inside the ventilation collar 33, and the height of the heating ring is adapted to the height of the ventilation collar 33 to ensure the heating area of ​​the dyeing cup holder 2.

[0064] In some embodiments, the dyeing apparatus with precise temperature control further includes a dyeing chamber 4, a dyeing cup holder 2 disposed inside the dyeing chamber 4, and during dyeing, the dyeing cup 1 and the dyeing cup holder 2 are sealed inside the dyeing chamber 4.

[0065] An electric rotary joint 41 is installed on the dyeing box 4. The electric rotary joint 41 is fixedly connected to the dyeing cup holder 2. An external driving component 42 (such as a motor) drives the electric rotary joint 41 to rotate. The electric rotary joint 41 drives the dyeing cup holder 2 and the dyeing cup 1 to rotate synchronously inside the dyeing box 4.

[0066] The electric rotary joint 41 is installed with the dyeing chamber 4, and the dyeing cup holder 2 is fixedly connected to the electric rotary joint 41 and driven to rotate by the electric rotary joint 41. The dyeing cup holder 2 is installed with the dyeing chamber 4 through the electric rotary joint 41. One end of the electric rotary joint 41 passes through the dyeing chamber 4 and is fixedly connected to the outer wall of the dyeing cup holder 2. Generally, to ensure the balance of the dyeing cup 1, the axis of the electric rotary joint 41 is fixedly connected to the outer wall of the dyeing cup holder 2 at or near the middle position in the height direction.

[0067] In some embodiments, the temperature control component further includes a cooling component, which is electrically connected to the control component, and the control component controls the cooling state of the cooling component based on the real-time temperature of the dye liquor obtained by the temperature probe 31.

[0068] In this embodiment, a cooling component is provided to cool the dyeing cup 1 when needed, adapting to different dyeing process requirements. The cooling component allows for rapid cooling of the dyeing cup 1 when it is at a high temperature, shortening the dyeing process time and improving dyeing efficiency.

[0069] In this embodiment, the cooling component is electrically connected to the control component, and the control component controls the cooling state of the cooling component based on the real-time temperature of the dye solution obtained by the temperature probe 31. The temperature probe 31, the heating component 32, the cooling component, and the control component form a closed-loop temperature control feedback system, realizing automatic temperature measurement and control, precise and rapid temperature control, and eliminating temperature control delay.

[0070] In some embodiments, the cooling component includes a fan, an air inlet duct 53, an air outlet 54, an air inlet 51, and an air outlet 52.

[0071] See Figure 4 and Figure 5Both the air inlet 51 and the air outlet 52 are located on the rear side wall of the dyeing chamber 4, that is, on the side wall opposite to the opening of the dyeing chamber. The fan is located outside the dyeing chamber 4. The air inlet duct 53 is located outside the dyeing chamber 4, with one end connected to the fan and the other end connected to the air inlet 51. The air outlet duct 54 is located outside the dyeing chamber 4, with one end connected to the air outlet 52 and the other end connected to an air collection device. The air outlet 52 is equipped with a one-way valve 55.

[0072] When it is necessary to cool down the dyeing cup 1, turn off the heating element 32, start the fan, and blow cold air or room temperature air into the dyeing box 4. The air pressure inside the sealed dyeing box 4 increases, and the one-way valve is opened under high pressure, so that the gas inside the dyeing box 4 is transported out through the one-way valve 55, the exhaust port 52 and the exhaust pipe 54, and the hot air inside the dyeing box 4 is output, so as to realize the ventilation inside the dyeing box 4 and cool down the dyeing cup 1.

[0073] A fan, an air inlet duct 53, and an air outlet duct 54 are installed inside the dyeing machine. A fan is installed on each air inlet duct 53, and each air outlet duct 54 is connected to the main exhaust duct. The other end of the main exhaust duct extends to the outside of the dyeing machine or is connected to a gas collection device to collect and treat the hot air discharged from the dyeing box 4.

[0074] In some embodiments, the check valve is electrically connected to the control component, which can control the check valve to open automatically, further facilitating the discharge of hot air from the dyeing chamber 4 and cooling the dyeing cup 1 inside the dyeing chamber 4.

[0075] In some embodiments, the control component includes a controller that receives information from a temperature probe regarding the dye solution in the dyeing cup, and then automatically controls the operation of the heating element 32 or the cooling element based on the dye solution temperature set in the process. Specifically, the controller controls the heating ring or the fan to operate, thereby controlling the temperature rise or fall of the dye solution. The controller employs existing technologies such as a PID temperature controller or a PLC controller.
