Abstract
Description
Technical Field
[0001] This utility model relates to the field of dyeing equipment technology, and in particular to a high-efficiency temperature-controlled dyeing device. Background Technology
[0002] Dyeing equipment is widely used in industries such as textiles, leather, and plastics. By controlling the temperature, time, and dye concentration of the dye liquor, it enables the dyed materials to obtain a uniform and stable color. Temperature control is a crucial factor in the dyeing process. It not only affects the solubility and diffusion rate of the dye but also directly determines the uniformity and color fastness of the dyeing. Therefore, dyeing equipment is usually equipped with a heating system to maintain the dye liquor within a specific temperature range.
[0003] Traditional dyeing equipment mainly relies on electric heating, steam heating, or direct heating of the coil when heating the dye liquor. However, traditional equipment usually adopts local heating methods, such as bottom or side wall heating, which can easily lead to excessively high local temperatures while other areas are colder, creating a temperature difference. This results in uneven heating of the dye liquor, which affects the uniform diffusion of the dye, leading to uneven dyeing effect and even color difference problems, thus causing poor dyeing results. Therefore, we propose this utility model. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient temperature-controlled dyeing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency temperature-controlled dyeing device includes a dyeing chamber. A mounting frame is slidably mounted on the top surface of the dyeing chamber. The mounting frame is U-shaped. A turbulence structure for uniform dye liquor temperature is provided on one side of the dyeing chamber. A temperature control structure for controlling the dye liquor temperature is provided on the outer wall of the dyeing chamber. The turbulence structure includes several movable rods fixed to the bottom surface of the mounting frame. A turbulence plate is fixed between two adjacent movable rods. A mounting plate is fixed to one side of the dyeing chamber. A mounting sleeve is fixed to one side of the mounting plate. A connecting shaft is slidably mounted inside the mounting sleeve. One end of the connecting shaft passes through one side of the mounting plate and is fixed to one side of the mounting frame.
[0007] As a further embodiment of this utility model, a motor is fixed on the top surface of the mounting plate, the output end of the motor is splinedly connected to one end of the connecting shaft, an annular groove is provided on the inner circular wall of the mounting sleeve, a fixed shaft is slidably arranged inside the annular groove, the fixed shaft is fixed to the outer circular wall of the connecting shaft, a circulating pump is fixed on the front side of the dyeing box, and the pump's pumping end and discharge end are both connected to the inside of the dyeing box.
[0008] As a further embodiment of this utility model, the temperature control structure includes a jacket fixed to the outer wall of the dyeing box, a heating coil fixed inside the jacket, a temperature sensor fixed to one side of the inner wall of the dyeing box, and a PLC controller fixed to one side of the jacket. The temperature sensor and the heating coil are both electrically connected to the PLC controller.
[0009] As a further embodiment of this utility model, the outer wall surface of the jacket is connected and fixedly equipped with a replenishing pipe and a draining pipe, which are arranged vertically, and the draining pipe is connected and fixedly equipped with a valve.
[0010] As a further embodiment of this utility model, an insulation layer is fixed inside the jacket, and the insulation layer is made of rock wool.
[0011] As a further embodiment of this utility model, the dyeing box is provided with two first tension rollers rotating inside, and two second tension rollers rotating inside, with the first tension rollers located above the second tension rollers.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This dyeing equipment, through the design of a turbulence and temperature control structure, allows operators to inject heating oil into the jacket and activate the heating coil via a PLC controller to heat the oil and dyeing chamber. As the dye liquor heats up, a temperature sensor monitors the temperature in real time and sends feedback to the PLC controller once the set range is reached, controlling the heating coil to stop heating. The heating oil is used to store heat and maintain the temperature. Simultaneously, the operator starts the motor, which drives the connecting shaft to rotate. The fixed shaft slides and reciprocates within the annular groove, thereby pushing the mounting frame to swing. This causes the turbulence plate to agitate the dye liquor, promoting mixing between the bottom and upper layers and preventing sedimentation. The circulating pump continuously draws the bottom dye liquor and transports it to the upper layer, enhancing flow, ensuring uniform heating, avoiding temperature differences, and improving the dyeing effect.

[0023] Reference Figures 1-5A high-efficiency temperature-controlled dyeing device includes a dyeing chamber 1. A mounting frame 2 is slidably mounted on the top surface of the dyeing chamber 1. The mounting frame 2 is U-shaped. A turbulence structure for uniform dye liquor temperature is provided on one side of the dyeing chamber 1. A temperature control structure for controlling the dye liquor temperature is provided on the outer wall of the dyeing chamber 1. The turbulence structure includes several movable rods 203 fixed to the bottom surface of the mounting frame 2. A turbulence plate 204 is fixed between two adjacent movable rods 203. A mounting plate 205 is fixed to one side of the dyeing chamber 1. A mounting sleeve 206 is fixed to one side of the mounting plate 205. A connecting shaft 207 is slidably mounted inside the mounting sleeve 206. One end of the connecting shaft 207 passes through one side of the mounting plate 205 and is fixed to one side of the mounting frame 2.
[0024] In this embodiment, a motor is fixed on the top surface of the mounting plate 205, and the output end of the motor is splinedly connected to one end of the connecting shaft 207. An annular groove 202 is provided on the inner circular wall of the mounting sleeve 206, and a fixed shaft 201 is slidably arranged inside the annular groove 202. The fixed shaft 201 is fixed to the outer circular wall of the connecting shaft 207. A circulating pump 3 is fixed on the front side of the dyeing box 1, and the pumping end and the discharge end of the circulating pump 3 are both connected to the interior of the dyeing box 1.
[0025] In this embodiment, the temperature control structure includes a jacket 301 fixed to the outer wall of the dyeing chamber 1. A heating coil 302 is fixed inside the jacket 301. A temperature sensor 303 is fixed to one side of the inner wall of the dyeing chamber 1, and a PLC controller is fixed to one side of the jacket 301. Both the temperature sensor 303 and the heating coil 302 are electrically connected to the PLC controller. Through the turbulence-inducing structure and the temperature control structure, the operator injects heating oil into the jacket 301 and activates the heating coil 302 via the PLC controller to heat the heating oil and the dyeing chamber 1. As heating progresses, the dye solution in the dyeing chamber 1 gradually heats up. The temperature sensor 303 monitors the temperature of the dye solution in real time. When the temperature reaches the set range, the temperature sensor 303 feeds back the detection signal to the PLC controller, which then controls the PLC controller. The device then controls the heating coil 302 to stop heating, while the heat accumulated in the heating oil continues to maintain the temperature inside the dyeing chamber 1, achieving efficient heat preservation. While heating the dye liquor, the operator starts the motor, driving the connecting shaft 207 to rotate. When the connecting shaft 207 rotates, the fixed shaft 201 slides in the annular groove 202 and moves back and forth along the trajectory of the annular groove 202, thereby pushing the mounting frame 2 to swing, causing the baffle plate 204 to continuously agitate the flow of the dye liquor inside the dyeing chamber 1, promoting full mixing of the bottom dye liquor and the upper dye liquor, and preventing dye sedimentation. In addition, the circulating pump 3 continuously draws the bottom dye liquor and transports it to the upper layer, further enhancing the uniform flow of the dye liquor, thereby effectively avoiding temperature differences during the heating process, improving the overall uniformity of the dye liquor, and ultimately significantly improving the dyeing effect of the equipment.
[0026] In this embodiment, a replenishment pipe 4 and a drain pipe 401 are fixedly connected to the outer wall of the jacket 301. The replenishment pipe 4 and the drain pipe 401 are arranged vertically. A valve is fixedly connected to the drain pipe 401. The drain pipe 401 and the replenishment pipe 4 make it convenient for workers to drain and replenish the heating oil in the jacket 301.
[0027] In this embodiment, an insulation layer 5 is fixed inside the jacket 301. The insulation layer 5 is made of rock wool and can improve the insulation effect of the jacket 301.
[0028] In this embodiment, two first tension rollers 6 are rotatably arranged inside the dyeing box 1, and two second tension rollers 601 are rotatably arranged inside the dyeing box 1. The first tension rollers 6 are located above the second tension rollers 601. Both the first tension rollers 6 and the second tension rollers 601 are located between two adjacent movable rods 203. The travel of the movable rods 203 is less than the distance between the movable rods 203 and the first tension rollers 6 and the second tension rollers 601. When dyeing, the worker can put the fabric on the first tension roller 6, then pass the fabric through the two second tension rollers 601, so that the top surface of the fabric is in contact with the second tension rollers 601, and then the bottom surface of the fabric is in contact with the second first tension roller 6, thereby tensioning and dyeing the fabric.
[0029] Working Principle: During use, the operator injects heating oil into the jacket 301 and activates the heating coil 302 via the PLC controller to heat the heating oil and dyeing chamber 1. As heating progresses, the dye liquor in the dyeing chamber 1 gradually heats up. The temperature sensor 303 monitors the temperature of the dye liquor in real time. When the temperature reaches the set range, the temperature sensor 303 feeds back the detection signal to the PLC controller, which then controls the heating coil 302 to stop heating. The heat accumulated in the heating oil continues to maintain the temperature inside the dyeing chamber 1, achieving efficient heat preservation. While heating the dye liquor, the operator starts the motor, driving the connecting shaft 207 to rotate. When the connecting shaft 207 rotates, the fixed shaft 201 slides within the annular groove 202 and reciprocates along the trajectory of the annular groove 202, thereby pushing the mounting frame 2 to swing. The baffle plate 204 continuously agitates the flow of dye liquor inside the dyeing tank 1, promoting thorough mixing of the bottom and upper dye liquors and preventing dye sedimentation. In addition, the circulating pump 3 continuously draws the bottom dye liquor and transports it to the upper layer, further enhancing the uniform flow of the dye liquor. This effectively avoids temperature differences during heating, improves the overall uniformity of the dye liquor, and ultimately significantly improves the dyeing effect of the equipment. The drain pipe 401 and the replenishment pipe 4 facilitate the drainage and replenishment of the heating oil in the jacket 301 by the staff. The insulation layer 5 can improve the insulation effect of the jacket 301. When dyeing, the staff can place the fabric on the first tension roller 6, then pass the fabric through the two second tension rollers 601, so that the top surface of the fabric is in contact with the second tension roller 601, and then the bottom surface of the fabric is in contact with the second first tension roller 6, thereby tensioning and dyeing the fabric.
