Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing technology, and in particular to a printing and dyeing equipment with precise temperature control, liquid level control and material circulation. Background Technology

[0002] In the printing and dyeing industry, printing and dyeing equipment is the key device for completing the printing and dyeing process of fabrics. Traditional printing and dyeing equipment still has many problems in operation.

[0003] On the one hand, during fabric printing and dyeing, it is difficult to ensure that the fabric is stably and fully immersed in the dye solution, which can lead to uneven printing and dyeing and affect the quality of the fabric. On the other hand, it is inconvenient to adjust the tension of the fabric during the conveying process, and it is impossible to flexibly adjust it according to the characteristics of different fabrics. This can easily cause wrinkles, stretching and deformation of the fabric during conveying, further reducing the quality of printing and dyeing.

[0004] On the other hand, the temperature and level control of the dye solution are not precise enough. Temperature fluctuations affect the activity of the dye and the dyeing effect, and traditional equipment cannot maintain the temperature of the dye solution within a suitable range. At the same time, unstable liquid levels can lead to inconsistent dyeing of the fabric, and the dye solution cannot be replenished in time when the liquid level is too low, nor can it be automatically stopped when the liquid level is too high, affecting the continuity and stability of printing and dyeing production.

[0005] To address the aforementioned issues, this utility model proposes a printing and dyeing equipment with precise temperature control, liquid level control, and material circulation. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as unstable dyeing during fabric printing and dyeing, inconvenient tension adjustment, and inaccurate control of dye solution temperature and level, which easily affect printing and dyeing quality and production stability. The invention proposes a printing and dyeing equipment with precise temperature control, level control, and material circulation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A dyeing and printing equipment with precise temperature control, liquid level control, and material circulation includes: The dye box has a base at the bottom and support frames on both sides. A first conveying roller is rotatably installed on the support frames near the top. The pressing assembly includes a support plate fixed to the top of the dye box, a lifting bracket located below the support plate, and pressing rollers rotatably mounted at both ends of the lifting bracket. The adjustment assembly includes extended side plates fixed to both sides of the dye box, a first guide rod and a double-threaded screw mounted on the extended side plates, two mounting brackets slidably connected to the top of the dye box, a movable seat fixed to the mounting brackets, and a second conveying roller rotatably mounted on the mounting brackets. The movable seat is slidably engaged with the first guide rod or threadedly engaged with the double-threaded screw. Rotating the double-threaded screw drives the two second conveying rollers to move towards or away from each other to adjust the fabric tension. The lifting bracket drives the pressing roller to rise and fall, pressing the fabric below the liquid surface of the dye box.

[0008] In one possible design, the lifting bracket is C-shaped, with a fixed plate fixed inside. A second guide rod is installed on the top of the fixed plate, and the second guide rod slides through the support plate. A cylinder is installed on the top of the support plate, and the output shaft of the cylinder is connected to the top of the fixed plate.

[0009] In one possible design, the base houses the main body of a heating device, and the bottom inner wall of the dye box is provided with a heating tube electrically connected to the main body of the heating device; a temperature sensor is provided on one side of the dye box, with its detection end extending into the interior of the dye box.

[0010] In one possible design, a motor is mounted on one side of one of the support frames, and the output shaft of the motor is connected to one end of the adjacent first conveyor roller.

[0011] In one possible design, an inlet / outlet pipe runs through one side of the dye tank, the inlet / outlet pipe is located near the bottom of the dye tank, it is equipped with a valve, and is connected to an external feeding device.

[0012] In one possible design, a second liquid level sensor is inserted through one side of the dye tank, located near the top of the dye tank; an L-shaped bracket is installed on one side of the lifting bracket, and a first liquid level sensor is inserted through the bottom of the L-shaped bracket, the height of the first liquid level sensor being higher than the horizontal plane where the two pressing rollers are located.

[0013] In one possible design, a control module is installed inside the base.

[0014] In one possible design, the temperature sensor and the main body of the heating device are both electrically connected to the control module; the first liquid level sensor and the second liquid level sensor are both electrically connected to the control module.

[0015] In this application, during the fabric conveying process, a motor drives the first conveying roller to rotate, which continuously carries the fabric into the area above the dye box. The lifting bracket, pushed by a cylinder, descends along the second guide rod, causing the pressing roller to contact the fabric surface and stably press it into the dye solution, ensuring thorough immersion. A second conveying roller is provided between the first conveying roller and the adjacent pressing roller to assist in the stable conveying of the fabric. The operator can adjust the distance between the two moving seats by rotating the double-threaded screw, thereby changing the distance between the two second conveying rollers, thus altering the degree of bending of the fabric during conveying, and consequently adjusting the fabric tension during conveying.

[0016] The equipment also includes a heating element that heats the dye solution via heating pipes. A temperature sensor monitors the solution temperature in real time and transmits the data to the control module. The control module adjusts the heating element's operation based on set values ​​to maintain the temperature within a predetermined range. Inlet and outlet pipes connect to external feeding equipment, and the first liquid level sensor adjusts its height accordingly with the lifting support. When the first liquid level sensor detects the liquid level is below the minimum position, the control module notifies the external equipment to replenish the dye tank using the inlet and outlet pipes. When the second liquid level sensor detects the liquid level has reached the maximum position, the control module notifies the external equipment to stop adding dye solution, thus maintaining a stable liquid level in the dye tank.

[0017] Throughout the process, the control module coordinates the operation of the motor, cylinder, heating equipment, and sensors to ensure the continuity and stability of temperature control, liquid level control, and fabric conveying. After dyeing, the fabric can be discharged via the first conveyor roller on the other side for subsequent processing stages.

[0018] Beneficial effects: In this utility model, the dyeing and printing equipment with precise temperature control, liquid level control, and material circulation can, during the fabric dyeing and printing process, apply stable pressure to the conveyed fabric through the pressing component, allowing the fabric to be fully immersed in the dye solution. Combined with auxiliary conveying components, this effectively avoids uneven dyeing caused by insufficient contact with the dye. Regarding fabric tension adjustment, by adjusting the distance between relevant components, the degree of bending during fabric conveying can be changed, thereby achieving flexible adjustment of fabric tension without frequent manual operation, ensuring the stability of fabric conveying and reducing fabric stretching deformation or conveying jams. In this invention, a dyeing and printing equipment with precise temperature control, liquid level control, and material circulation works in conjunction with a heating component and a temperature detection component. The temperature detection component can acquire the dye solution temperature data in real time and transmit the data to the control module. The control module adjusts the working state of the heating component according to the predetermined temperature range, so that the dye solution temperature is always maintained in a suitable range, avoiding the influence of temperature fluctuations on dye activity, ensuring the consistency of dyeing effect of different batches of fabric, and reducing the problems of color difference and insufficient dyeing fastness. In this invention, a dyeing and printing equipment with precise temperature control, liquid level control, and material circulation is provided. Two liquid level detection components monitor the highest and lowest liquid level positions of the dye solution, respectively. When the liquid level is below the lowest position, the control module can automatically start the dye replenishment process. When the liquid level reaches the highest position, the control module can stop replenishment. There is no need for continuous manual monitoring of the liquid level, which avoids dyeing problems caused by insufficient dye and also prevents waste caused by excessive dye overflow. In this invention, a dyeing and printing equipment with precise temperature control, liquid level control, and material circulation is provided. The control module can coordinate the operation of the motor, cylinder, heating components, and various detection components, so that the fabric conveying, temperature control, and liquid level adjustment processes cooperate with each other, ensuring the continuity and stability of the entire dyeing and printing process, improving dyeing and printing efficiency, reducing dyeing quality fluctuations caused by improper coordination of various modules, and facilitating the smooth progress of subsequent processing steps.

[0019] In this invention, the dyeing and printing equipment ensures that the fabric is fully immersed in dye through a pressing component, reducing uneven dyeing; the tension adjustment mechanism can flexibly adapt to different fabrics and ensure smooth conveying; the temperature control system maintains a stable dye solution temperature, effectively reducing color difference; automatic liquid level control avoids insufficient dye or overflow, reducing material waste; overall, all modules work together under the coordination of the control unit, effectively improving the continuity, stability and production efficiency of the dyeing and printing process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In one embodiment: Refer to Figure 1-4 A printing and dyeing equipment, comprising: The dye box 1 is used to store the dye solution. Support frames 3 are fixedly installed on both sides of the dye box 1. First conveyor rollers 4 are rotatably mounted on the top positions of both support frames 3. These two first conveyor rollers 4 are used to transport the fabric to be dyed. A motor 5 is fixedly installed on one side of one of the support frames 3. One end of the output shaft of the motor 5 is fixedly connected to one end of the adjacent first conveyor roller 4. When the motor 5 is started, it drives the first conveyor roller 4 to rotate, thereby transporting the fabric.

[0024] In this embodiment, a pressing assembly is also provided for pressing the fabric during transport, ensuring its stable immersion in the dye within the dye tank 1. The pressing assembly includes a support plate 14 fixedly installed on the top of the dye tank 1, with the support plate 14 located at the center of the dye tank 1. A lifting bracket 12 is positioned below the support plate 14. The lifting bracket 12 is C-shaped, with pressing rollers 13 rotatably mounted at both ends. Both pressing rollers 13 are in contact with the fabric during transport, achieving fabric transport and pressing. Multiple fixing plates 20 are fixedly installed inside the lifting bracket 12.

A cylinder 15 is fixedly installed on the top of the support plate 14, with one end of the cylinder 15 penetrating the support plate 14 and fixedly connected to the top of the corresponding fixing plate 20. When the cylinder 15 is activated, the output shaft extends and retracts, driving the lifting bracket 12 to rise and fall, thereby causing the pressing rollers 13 to rise and fall, adapting to the pressing requirements of fabrics of different thicknesses.

[0025] In this embodiment, an adjustment assembly is also provided for squeezing and pushing the fabric during conveying to adjust its conveying tension. The adjustment assembly includes extended side plates 7 fixedly installed on both sides of the dye box 1, with both extended side plates 7 located near the top of the dye box 1. A first guide rod 18 is fixedly installed on the top of one extended side plate 7 via a bracket, and a double-threaded screw 19 is rotatably installed on the top of the other extended side plate 7 via a bracket. Two second conveying rollers 8 are provided on the top of the dye box 1, and mounting brackets 16 are rotatably installed at both ends of the two second conveying rollers 8. Multiple mounting brackets 16 are slidably connected to the top of the dye box 1, and movable seats 17 are fixedly installed on the side of the multiple mounting brackets 16 near the adjacent extended side plate 7.

Rotating the double-threaded screw 19 causes the two movable seats 17 to move towards or away from each other, driving the two second conveying rollers 8 to move, thereby adjusting the distance between the two second conveying rollers 8 and completing the tension adjustment of the fabric during conveying. The two second conveying rollers 8 provide auxiliary conveying of the fabric between the first conveying roller 4 and the pressing roller 13.

When the heating device body 9 is working, the temperature of the dye solution in the dye tank 1 can be adjusted through the heating tube 10. The heating device body 9 and the heating tube 10 are the same as those in the patent with publication number CN222878401U.

[0027] In this embodiment, an inlet / outlet pipe 6 is fixedly installed on one side of the dye tank 1. The inlet / outlet pipe 6 is located near the bottom of the dye tank 1, and a valve is installed on the inlet / outlet pipe 6. The inlet / outlet pipe 6 is connected to an external feeding device. When the valve is opened, the external feeding device can replenish the dye solution into the dye tank 1 through the inlet / outlet pipe 6.

[0028] In this embodiment, a second liquid level sensor 24 is fixedly inserted through one side of the dye tank 1. The second liquid level sensor 24 is located near the top of the dye tank 1 and is used to detect the highest position of the dye solution surface. An L-shaped bracket 22 is fixedly installed on one side of the lifting bracket 12. A first liquid level sensor 23 is fixedly inserted through the bottom of the L-shaped bracket 22. The height of the first liquid level sensor 23 is higher than the horizontal plane where the two pressing rollers 13 are located, and it is used to detect the lowest position of the dye solution surface. When the liquid level is lower than the detection position of the first liquid level sensor 23 or higher than the detection position of the second liquid level sensor 24, the first liquid level sensor 23 and the second liquid level sensor 24 will feed back the liquid level information to the control module 11. The liquid level sensor is the same as that in the patent with publication number CN223295001U. This application can be used in the field of fabric printing and dyeing technology, or in other fields applicable to this application.

[0029] In another embodiment: Reference Figure 1 , 2 A printing and dyeing equipment with precise temperature control, liquid level control and material circulation, which is applied to the field of fabric printing and dyeing technology. In this embodiment, a temperature sensor 25 is fixedly installed on one side of the dye tank 1. The detection end of the temperature sensor 25 extends into the dye tank 1, enabling it to detect the temperature of the dye solution inside the dye tank 1 in real time and feed the temperature information back to the control module 11. The temperature sensor 25 is the same as that in the patent with publication number CN223293884U.

[0030] In this embodiment, a control module 11 is fixedly installed inside the base 2. The control module 11 receives information from the temperature sensor 25, the first liquid level sensor 23, and the second liquid level sensor 24, and controls the operation of the heating equipment body 9, cylinder 15, and other components according to a preset program to achieve temperature control and liquid level control of the printing and dyeing equipment.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 5, the heating equipment body 9, the control module 11, the cylinder 15, and the corresponding liquid level sensor and temperature sensor are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] The working principle and usage process of this technical solution are as follows: During the fabric conveying process, the motor 5 drives the first conveying roller 4 to rotate, which can continuously drive the fabric into the area above the dye box 1. The lifting bracket 12 is pushed down along the second guide rod 21 by the cylinder 15, so that the pressing roller 13 contacts the fabric surface and presses it stably into the dye solution to ensure sufficient dyeing. A second conveying roller 8 is set between the first conveying roller 4 and the adjacent pressing roller 13, which can assist in the stable conveying of the fabric; the operator can adjust the distance between the two moving seats 17 by rotating the double threaded screw 19, thereby changing the distance between the two second conveying rollers 8, thereby changing the degree of bending of the fabric during the conveying process, and thus realizing the adjustment of the fabric tension during the conveying.

[0033] The equipment also includes a heating element 9, which heats the dye solution via a heating tube 10. A temperature sensor 25 monitors the solution temperature in real time and transmits the data to the control module 11. The control module 11 adjusts the operating state of the heating element 9 according to the set value to maintain the temperature within a predetermined range. Inlet and outlet pipes 6 connect to an external feeding device, and the first liquid level sensor 23 adjusts its height accordingly as the lifting bracket 12 moves. When the first liquid level sensor 23 detects that the liquid level is below the minimum position, the control module 11 notifies the external device to replenish the dye solution into the dye tank 1 using the inlet and outlet pipes 6. When the second liquid level sensor 24 detects that the liquid level has reached the maximum position, the control module 11 notifies the external device to stop adding dye solution, thus maintaining a stable liquid level in the dye tank 1.

[0034] Throughout the process, the control module 11 coordinates the operation of the motor 5, cylinder 15, heating equipment body 9, and sensors to ensure the continuity and stability of temperature control, liquid level control, and fabric conveying. After dyeing, the fabric can be discharged through the first conveyor roller 4 on the other side to enter the subsequent processing stage.
