Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a high-temperature color-fixing device for fabric printing and coloring. Background Technology

[0002] In the field of fabric textile and printing processing, high-temperature color fixing after printing and coloring is the core process to ensure the quality of finished products. Its technical effect directly determines the color fastness, pattern integrity and durability of printed fabrics.

[0003] Patent CN 215598015 U discloses a high-temperature color-fixing device for fabric printing and coloring. In order to accelerate the color fixing of the fabric, a heating device heats the air blown out by the blower, thereby accelerating the drying and color fixing of the fabric. After the operator fixes the fabric onto the conveying device, he sends a command to the controller. The controller sends a signal to the conveying device, which drives the fabric to move. At the same time, the controller sends a signal to start the blower and heating tube. The lower air inlet and heating tube are also started. With the cooperation of the lower air inlet and heating tube, hot air is blown out from the upper air outlet and the lower air outlet to perform high-temperature color fixing on the upper and lower surfaces of the fabric.

[0004] While the aforementioned technologies can utilize wind power for heating to achieve color fixation, the convective heat transfer efficiency of wind is low. Continuous delivery of hot air is required to gradually raise the fabric temperature to reach the target color fixation temperature, thus affecting processing efficiency. Furthermore, fabrics of different shades are prone to uneven color fixation of printed patterns under the action of a single wind force for extended periods, leading to compromised product quality. Therefore, innovation is needed in this technology. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature color-fixing device for fabric printing and coloring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature color-fixing device for fabric printing, comprising a fabric processing box, on both sides of the front of the fabric processing box having hinged doors for rotation; symmetrically installed feeding rollers and receiving rollers on one side inside the fabric processing box; a conveying assembly also installed inside the fabric processing box; a wind-powered color-fixing assembly also installed on one side of the fabric processing box; hydraulic push rods are installed at the top and bottom of the inner wall of the fabric processing box, and flat plate heating assemblies are provided on the two hydraulic push rods; the wind-powered color-fixing assembly includes a fixed installation... A fan is located at the bottom of one side of the fabric processing box. A diverter pipe is fixedly installed at the output end of the fan. Air delivery pipes are fixedly installed at both the upper and lower ends of the diverter pipes. A heating box is fixedly installed at the other end of each of the two air delivery pipes. Multiple air outlets are symmetrically installed on the adjacent side of each of the two heating boxes. Heating resistance wires are fixedly installed on the inner wall of each of the two heating boxes near the air outlets. Solenoid valves are installed on each of the two air delivery pipes. The flat plate heating assembly includes a heating plate with adjacent hydraulic push rod output ends fixedly installed. A silicone layer is fixedly installed on the adjacent side of each of the two heating plates.

[0007] As a preferred technical solution of this utility model, the conveying assembly includes conveyor belts fixedly installed at the top and bottom four corners of the fabric processing box. Mounting frames are rotatably installed on the inner walls of both sets of conveyor belts. Two motors are fixedly installed on the back of the fabric processing box. The output ends of the two motors pass through the adjacent mounting frames and are fixedly connected to one of the shafts of the conveyor belts.

[0008] As a preferred technical solution of this utility model, a fabric body is installed on the feeding roller, and the fabric body is conveyed by two fabric bodies in sequence and then wound and rolled up by the conveying component.

[0009] As a preferred technical solution of this utility model, a spectral sensor is fixedly installed on the outer wall of both heating boxes. Both spectral sensors are located in the clockwise direction of the fabric body conveying. The temperature of the heating resistance wire and heating plate at the top is lower than the temperature of the heating resistance wire and heating plate at the bottom.

[0010] As a preferred embodiment of this utility model, a controller is installed on the outside of the fabric processing box, and the motor, heating resistance wire, solenoid valve and heating plate are all electrically connected to the controller through a spectral sensor.

[0011] As a preferred technical solution of this utility model, two locking grooves are symmetrically opened on the front side of one side of the fabric processing box. The inner walls of the two locking grooves are fitted with limit frames. The back of the two limit frames are provided with mounting grooves. One end of the feeding roller and the receiving roller are rotatably connected to the inner wall of the adjacent mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the combination of a wind-driven color-fixing component and a hydraulic push rod, compensates for the low efficiency of wind convection heat transfer by direct heat conduction through a flat plate heating component after wind-driven color fixing. Furthermore, by utilizing a spectral sensor to detect the depth of the printed color in real time, it can accurately match the color-fixing requirements and select the appropriate heating combination. Dark-colored prints require stronger heat to ensure full dye penetration; therefore, a combination of the bottom wind-driven color-fixing component and the flat plate heating component can be selected to enhance the color-fixing effect and avoid the problems of insufficient color fixing and low color fastness in dark colors caused by traditional single heating. Light-colored prints require gentle heating to prevent color change or fiber damage; therefore, a combination of the top wind-driven color-fixing component and the flat plate heating component can be selected to ensure the purity of light-colored prints, thereby significantly improving the color-fixing consistency of fabrics with different shades of print.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figures 1-3 This utility model provides a technical solution:

[0021] A high-temperature color-fixing device for fabric printing includes a fabric processing box 1. Both sides of the front of the fabric processing box 1 are equipped with hinged doors 11. A feeding roller 2 and a receiving roller 3 are symmetrically installed on one side inside the fabric processing box 1. A conveying assembly 4 is also installed inside the fabric processing box 1. The cooperation between the feeding roller 2, the receiving roller 3, and the conveying assembly 4 enables continuous and stable fabric conveying, providing a foundation for batch color fixing. A wind-powered color-fixing assembly 6 is also installed on one side of the fabric processing box 1. Hydraulic push rods 8 are installed at the top and bottom of the inner wall of the fabric processing box 1, and flat plate heating components 9 are installed on the two hydraulic push rods 8. The wind-powered color-fixing assembly 6 includes a fan 61 fixedly installed at the bottom of one side of the fabric processing box 1. A diversion pipe 62 is fixedly installed at the output end of the device. A wind conveying pipe 63 is fixedly installed at both the upper and lower ends of the diversion pipe 62. A heating box 64 is fixedly installed at the other end of each of the two wind conveying pipes 63. Multiple air outlets 65 are symmetrically installed on the adjacent side of each of the two heating boxes 64. A heating resistance wire 66 is fixedly installed on the inner wall of each of the two heating boxes 64 near the air outlet 65. A solenoid valve is installed on each of the two wind conveying pipes 63. The solenoid valve can be used to open and close the corresponding wind conveying pipe 63, so that the airflow only passes through the side that needs to be heated. The flat plate heating assembly 9 includes a heating plate 91 with the output end of an adjacent hydraulic push rod 8 fixedly installed. A silicone layer 92 is fixedly installed on the adjacent side of each of the two heating plates 91.

[0022] Please see Figure 1 The conveying assembly 4 includes conveyor belts 41 fixedly installed at the top and bottom four corners of the fabric processing box 1. Mounting frames 42 are rotatably installed on the inner walls of both sets of conveyor belts 41. Two motors 43 are fixedly installed on the back of the fabric processing box 1. The output ends of the two motors 43 pass through the adjacent mounting frames 42 and are fixedly connected to one of the shafts of the conveyor belts 41. The mounting frames 42 play an auxiliary role in the installation of the conveyor belts 41, and the conveyor belts 41 play an auxiliary role in the conveying of the fabric body 5.

[0023] Please see Figure 1 Fabric body 5 is installed on the feeding roller 2. After being conveyed by two fabric bodies 5 in sequence, the fabric body 5 is wound and rolled up by the conveying component 4. The cooperation of the feeding roller 2, the conveying component 4 and the take-up roller 3 forms a complete closed loop of feeding, fixing and rolling, ensuring that the fabric can completely cover the fixing process. Every print can fully contact the wind heating and the flat plate heating, avoiding the problem of local missing fixing caused by incomplete conveying path.

[0024] Please see Figure 1Both heating chambers 64 have fixedly installed spectral sensors 7 on their outer walls. Both sensors 7 are located clockwise along the fabric body 5. The temperatures of the heating resistance wire 66 and heating plate 91 at the top are lower than those at the bottom. This clockwise design allows for monitoring the real-time temperature of the corresponding heating resistance wire 66 before the fabric enters the core color-fixing area, ensuring the hot air temperature reaches the preset requirements. Simultaneously, the dual sensors can independently monitor the temperatures of the upper and lower heating resistance wires 66, preventing temperature deviations caused by single monitoring and laying the foundation for stable subsequent heating. A controller is installed externally in the fabric processing chamber 1. The motor 43, heating resistance wire 66, solenoid valve, and heating plate 91 are all electrically connected to the controller via the spectral sensors 7.

[0025] Please see Figure 1 Two locking grooves 10 are symmetrically opened on the front side of one side of the fabric processing box 1. The inner walls of the two locking grooves 10 are fitted with limit frames 101. The back of the two limit frames 101 are provided with mounting grooves. One end of the feeding roller 2 and the receiving roller 3 are rotatably connected to the inner wall of the adjacent mounting groove. The cooperation between the locking grooves 10 and the limit frames 101 forms a detachable limiting structure, which effectively simplifies the feeding and changing process of the fabric roll.

[0026] Working principle: The operator installs the printed fabric body 5 onto the feed roller 2, and engages the corresponding limit frame 101 onto the engagement groove 10, aligning the mounting grooves into the mounting grooves of the feed roller 2 and the take-up roller 3. The switch door 11 is closed, and one end of the fabric is wound clockwise by the conveyor belt 41, passing through the fabric processing box 1, and finally wrapped onto the take-up roller 3. The motor 43 is started to drive the conveyor belt 41, continuously conveying the fabric at a stable speed within the processing box. During the detection stage, when the fabric passes through the detection area of ​​the spectral sensor 7, the spectral sensor 7 collects the light reflection characteristics of the printed surface in real time, transmitting the light / dark signal to the controller. The controller determines the printing type based on preset parameters (such as dark threshold and light threshold). If it is a light-colored print, it is determined that gentle heating is required, and the top heating resistance 66 is instructed to be heated. When the flat heating assembly 9 is started and the solenoid valve on the top air delivery pipe 63 is opened, the fan 61 starts. The generated airflow is sent into the heating box 64 through the diversion pipe 62 and the corresponding air delivery pipe 63. The heating resistance wire 66 heats the fabric to the target temperature, and then the high-temperature hot air is blown onto the fabric surface through the air outlet 65 to achieve preheating. After the air-fixing is completed, the hydraulic push rod 8 drives the heating plate 91 of the flat heating assembly 9 to descend so that the silicone layer 92 is tightly attached to the fabric printing area. The printing area is heated by direct heat conduction to achieve high-temperature fixing of light-colored printing. If it is dark-colored printing, the fabric body 5 is sent to the bottom for detection by the spectral sensor 7. Then, the fixing operation of dark-colored printing is carried out by the cooperation of the air-fixing assembly 6 and the flat heating assembly 9. After the fixing is completed, the take-up roller 3 is used to rewind the fabric.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
