Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile fabric dyeing machines, in particular to a dyeing machine for textile fabrics. BACKGROUND

[0002] Dyeing machines are special equipment used in the textile, leather, and plastic industries for dyeing materials. By controlling parameters such as temperature, pressure, and time, dyeing machines ensure that dye evenly penetrates fibers or substrates, achieving coloration. They come in various types and are suitable for different materials and process requirements.

[0003] Immersion dyeing machines are common dyeing machines often used in the dyeing process of textiles and clothing. The basic principle is to immerse the textile fabric in a liquid containing dye, allowing the textile fabric to interact with dye molecules to achieve dyeing. In actual immersion processing, to achieve continuous dyeing production, a pay-off roll is usually set at the head of the immersion tank, and a take-up roll is set at the tail of the immersion tank. The continuous immersion of the rolled fabric is achieved through the cooperation of the take-up and pay-off operations.

[0004] During immersion, the textile fabric needs to pass through multiple groups of guide rollers to maintain tension in the immersion tank, achieving uniform dyeing. Traditional immersion dyeing machines require textile fabric guiding and tensioning operations in the immersion tank. Therefore, before immersing a new roll of textile fabric, the dye in the immersion tank needs to be emptied to install the textile fabric, which is complex and repeatedly emptying can cause dye loss and pollution, affecting the immersion effect and greatly increasing the workload of workers.

[0005] After searching, the existing technology, the authorized patent document with publication number CN222349308U and publication date 2025.01.14, discloses a textile fabric immersion equipment, which includes a box body, a feeding roller and a pressure roller are rotatably arranged inside the box body for conveying textile fabric, and the height of the feeding roller is higher than that of the pressure roller. A tensioning mechanism is provided inside the box body, and the tensioning mechanism includes a first guide roller and a second guide roller rotatably arranged. Slides are formed on both sides of the inside of the box body, and sliding blocks are slidably arranged inside the slides. The second guide roller is rotatably arranged between the sliding blocks through bearings. A first fixed roller is rotatably arranged inside the box body through a bearing. A telescopic rod is fixedly connected to the top inside the box body. The utility model, by setting the first fixed roller, telescopic rod, compression spring and second fixed roller, the fabric enters the box body for immersion treatment through the feeding roller and pressure roller, then passes through the first guide roller and second guide roller, and finally reaches between the first fixed roller and second fixed roller. At this time, the compression spring inside the telescopic rod at the top of the box body pushes the telescopic rod and fixed frame to descend.

[0006] However, the device still has the following defects: although the textile fabric can be uniformly dyed and dried, the device is provided with multiple guide rollers and fixed rollers in the dip dyeing box. When each roll of textile fabric is replaced, the dye in the dip dyeing box needs to be emptied in advance to complete the guide installation operation of the textile fabric.

[0045] For example, as shown in Figures 4-6

[0046] The auxiliary dyeing mechanism 800 includes a first vertical plate 810 and a second vertical plate 820, two groups of connecting shafts 830 are symmetrically arranged between the first vertical plate 810 and the second vertical plate 820, a plurality of groups of annular grooves 821 are formed in the inner side wall of the second vertical plate 820, a linkage box 840 is fixedly connected to the outer side wall of the second vertical plate 820, a transmission box 850 is fixedly connected to the outer side wall of the first vertical plate 810, the top ends of the transmission box 850 and the linkage box 840 are respectively in transmission connection with the output ends of two groups of electric cylinders 130, two groups of sliding blocks 860 are fixedly connected to the outer side walls of the first vertical plate 810 and the second vertical plate 820, through holes 861 are formed in the four groups of sliding blocks 860, and four groups of limiting shafts 110 are movably attached to the four groups of through holes 861;

[0047] A plurality of groups of tensioning portions 870 are rotatably connected to the inner side wall of the first vertical plate 810, a gas guide pipe 851 is mounted in the transmission box 850, the gas guide pipe 851 and the air outlet pipe 940 are in communication with each other, a plurality of groups of rotating joints 852 are communicated on the gas guide pipe 851, the plurality of groups of rotating joints 852 are all penetrated through the first vertical plate 810 and communicated with a corresponding group of tensioning portions 870, a plurality of groups of annular worm gears 853 are all sleeved on the rotating joints 852, a worm 854 is rotatably connected to the inner wall of the transmission box 850, the worm 854 is in meshing connection with the plurality of groups of annular worm gears 853, and an adjusting motor 855 is mounted on the outer wall of the transmission box 850. One end of the adjusting motor 855 is in transmission connection with the worm 854.

[0048] ​The tensioning part 870 includes a strip-shaped block 871, which is a hollow structure. The interior of the strip-shaped block 871 is interconnected with one end of the rotating joint 852. Two sets of tensioning rollers 872 are symmetrically arranged on the strip-shaped block 871. Both sets of tensioning rollers 872 are hollow structures, and their interiors are interconnected with the interior of the strip-shaped block 871. A locking block 873 is fixedly connected to the other end of each set of tensioning rollers 872. The snap-fit ​​block 873 is movably fitted with a corresponding set of annular grooves 821. The tension roller 872 is covered with several sets of strip-shaped protrusions 874. The several sets of strip-shaped protrusions 874 are arranged in a ring array with the central axis of the tension roller 872 as the center. The several sets of strip-shaped protrusions 874 are movably fitted with the textile fabric. Several sets of air nozzles 875 are provided between each two adjacent sets of strip-shaped protrusions 874.

[0049] Specifically, in the initial state, the positions of several sets of tensioning sections 870 are as follows: Figure 4 In the state shown, one end of the textile fabric is passed sequentially through the bottom of a set of connecting shafts 830, through the middle of several sets of tensioning parts 870, and then through the bottom of another set of connecting shafts 830. By adjusting the motor 855 to drive the worm 854 to rotate, several sets of annular worm gears 853 rotate synchronously, thereby causing the rotary joint 852 to drive the corresponding set of tensioning parts 870 to rotate, thereby causing several sets of tensioning rollers 872 to rotate and tension the textile fabric, and causing the textile fabric to form a reciprocating folding state, thereby effectively increasing the length of the fabric dyed in a single immersion, thereby increasing the utilization rate of dye in the dyeing tank 100, and thus effectively improving the dyeing efficiency.

After the installation, pulling and tensioning of the textile fabric are completed, the auxiliary dyeing mechanism 800 is moved downward to the dye in the dyeing tank 100 by two sets of electric cylinders 130 for dyeing. Therefore, the fabric roll changing operation can be carried out without frequently sucking the dye in the dyeing tank 100, which greatly reduces the workload and improves the dyeing efficiency.

[0051] Furthermore, by allowing heated pure air to enter the interior of the tension roller 872 through the air outlet 940, and then spraying it into the dye through several sets of air nozzles 875 to generate convection and bubbles, the dyeing effect is effectively improved. In addition, by setting several sets of strip-shaped protrusions 874 to support the fabric, the textile fabric is effectively prevented from blocking the air nozzles 875.

[0052] Further, when the dyeing and winding operations of a roll of textile fabric are completed, the auxiliary dyeing mechanism 800 is moved upward to above the dyeing pool 100 by the two electric cylinders 130, the unwinding motor 230 and the winding motor 720 are synchronously reversed, thereby realizing reverse conveying of the textile fabric. At this time, the heated pure air is sprayed to the surface of the textile fabric by the plurality of air nozzles 875, so that the dyed textile fabric can be air-dried during the reverse conveying. The dyed and air-dried textile fabric is wound on the unwinding roller 220, so as to be disassembled and installed and dyed for the next roll of textile fabric.

[0053] As shown in Figure 7 .

[0054] The spraying box 610 is provided with an inlet chute 660 and an outlet chute 670. The inlet chute 660 is arranged near one side of the dyeing pool 100, and the outlet chute 670 is connected with the inside of the winding box 700. Two sets of limiting rollers 630 are arranged in the spraying box 610. Two sets of the limiting rollers 630 are arranged on one side of the inlet chute 660 and the outlet chute 670, respectively. The two side inner walls of the spraying box 610 are fixedly connected with spraying pipes 640. Two sets of the spraying pipes 640 are connected with the outlet of the liquid pump. A plurality of sets of liquid nozzles 650 are arranged on the two sets of spraying pipes 640, and the liquid nozzles 650 are all directed to the surface of the textile fabric.

[0055] Specifically, the textile fabric enters the spraying box 610 through the inlet chute 660, is limited by the two sets of limiting rollers 630, and is sprayed by the liquid nozzles 650 on the two sets of spraying pipes 640. The dyed textile fabric is fixed and the odor generated after dyeing is effectively removed. The sprayed textile fabric is guided out of the outlet chute 670 into the winding box 700 and is wound by the winding roller 710.

[0056] As shown in Figure 8 .

[0057] The extrusion section 500 includes two sets of fixing frames 510, both sets of fixing frames 510 are mounted on the dyeing tank 100, and a guide roller 520 and an extrusion roller 530 are arranged between the two sets of fixing frames 510. Both ends of the extrusion roller 530 are fixedly connected to a rotating shaft 540, and the two sets of rotating shafts 540 are rotatably connected to the two sets of fixing frames 510 respectively. One end of one set of rotating shafts 540 passes through the fixing frame 510 and is fixedly connected to an adjusting handle 560. A torsion spring 550 is arranged between the extrusion roller 530 and the two sets of fixing frames 510, and the two sets of torsion springs 550 are respectively sleeved on the two sets of rotating shafts 540. A scraper 570 is fixedly connected to the extrusion roller 530, and one end of the scraper 570 is attached to the guide roller 520.

[0058] Specifically, the tension of the torsion spring 550 causes the scraper 570 to adhere to the surface of the guide roller 520. By rotating the adjusting handle 560, the squeeze roller 530 drives the scraper 570 to rotate, causing the scraper 570 to separate from the guide roller 520. At this time, it is convenient to transport the textile fabric through the space between the guide roller 520 and the squeeze roller 530. After releasing the handle 560, the tension of the torsion spring 550 causes the scraper 570 to adhere to the surface of the textile fabric, so that the excess dye attached to the textile fabric is scraped off while the textile fabric is being transported, thereby avoiding waste of dye.

[0059] The working principle of the dyeing machine for textile fabrics proposed in this invention is as follows:

[0060] The textile fabric roll to be dyed is placed on the unwinding roller 220, which is installed between two sets of unwinding frames 210. One end of the textile fabric is pulled through between two sets of finishing rollers 400, which limit the movement of the textile fabric and make it flatter. Two sets of electric cylinders 130 drive the auxiliary dyeing mechanism 800 to move upward above the dyeing tank 100. The textile fabric is then passed through the auxiliary dyeing mechanism 800. In the initial state, the positions of several sets of tensioning parts 870 are as follows: Figure 4 In the state shown, one end of the textile fabric is passed through the bottom of a set of connecting shafts 830, through the middle of several sets of tensioning parts 870, and then through the bottom of another set of connecting shafts 830. After passing through the extrusion part 500 and the spray box 610, it enters the winding box 700 and is fixed to the winding roller 710. The textile fabric can be synchronously conveyed by the synchronous opening of the unwinding motor 230 and the winding motor 720. The auxiliary dyeing mechanism 800 drives the textile fabric to move downward into the liquid dye in the dyeing pool 100 for dyeing.

[0061] The motor 855 drives the worm 854 to rotate, so that the rotating joint 852 drives a corresponding set of tensioning parts 870 to rotate, so that the plurality of sets of tensioning rollers 872 rotate and tension the textile fabric, and drive the textile fabric to form a reciprocating folding state, thereby effectively increasing the length of the fabric immersed at a time, thereby improving the use rate of dye in the dyeing tank 100, thereby effectively improving the dyeing efficiency.

[0062] The air purifier 910 purifies the air, which is then input into the heater 930 by the air pump 920 for heating. The purified and heated air is introduced into the auxiliary dyeing mechanism 800 through the air outlet pipe 940. The purified and heated air enters the inside of the tensioning roller 872 through the air outlet pipe 940, and is then sprayed into the dye through the plurality of sets of air nozzles 875 to generate convection and air bubbles, thereby effectively improving the dyeing effect. The plurality of sets of strip-shaped protrusions 874 are arranged to support the fabric, effectively preventing the textile fabric from blocking the air nozzles 875. The purified and heated air is blown into the liquid dye, which is heated and generates air bubbles at the same time. The heating of the dye can improve the dyeing efficiency. The injection of air can effectively break the aggregation of dye molecules, making the dye particle size distribution more uniform. The micro-jet generated by the rupture of the air bubbles can enhance the penetration of the dye on the fiber surface. At the same time, the air flow promotes the convection of the dye, making the dye more uniform while reducing local temperature difference, thereby effectively avoiding dyeing color spots.

[0063] The tension of the torsional spring 550 causes the scraper 570 to adhere to the surface of the guide roller 520. Rotating the adjusting handle 560 causes the extrusion roller 530 to drive the scraper 570 to rotate, so that the scraper 570 is separated from the guide roller 520. At this time, it is convenient to transport the textile fabric through the guide roller 520 and the extrusion roller 530. After releasing the handle 560, the tension of the torsional spring 550 causes the scraper 570 to adhere to the surface of the textile fabric, so that the textile fabric is transported while the excess dye attached to the textile fabric is scraped off, thereby avoiding waste of dye.

[0064] The textile fabric enters the spraying box 610 through the feeding slot 660. The two sets of limiting rollers 630 limit the textile fabric. The two sides of the textile fabric are sprayed by the liquid nozzles 650 on the two sets of spraying pipes 640, respectively. The dyed textile fabric is fixed at the same time, effectively removing the odor generated after dyeing. The sprayed textile fabric is guided out of the discharge slot 670 into the winding box 700, and is wound by the winding roller 710.

[0065] When the dyeing and winding operations of a roll of textile fabric are completed, the auxiliary dyeing mechanism 800 is moved upward to the upper side of the dyeing pool 100 by the two sets of electric cylinders 130, so that the textile fabric is separated from the dye in the dyeing pool 100. The unwinding motor 230 and the winding motor 720 are synchronously and reversely rotated, so that the textile fabric is reversely transported. At this time, the heated pure air is sprayed to the surface of the textile fabric by the several sets of air nozzles 875, so that the dyed textile fabric can be air-dried during the reverse transportation. The textile fabric after the dyeing and air-drying operations is wound on the unwinding roller 220, so as to be disassembled and installed and dyed with the next roll of textile fabric.

[0066] Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood that the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalents, without departing from the spirit and scope of the technical solutions of the embodiments of the present application.
