Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, and in particular relates to a double-sided flannel waterless dyeing device. Background Technology

[0002] Double-sided flannel is a type of fabric treated with a special napping process, resulting in a fine, full pile covering both sides without revealing the weave, giving it a soft and smooth feel. Modern double-sided flannel is mostly made from 100% polyester fiber or a blend of polyester with cotton, wool, etc. Its core process involves using a napping machine to "hook out" the fibers on the fabric surface, creating a double-sided nap. Advanced processes also utilize techniques such as splitting and reverse napping to achieve double-sided napping. In the dyeing process of double-sided flannel, a dyeing machine is essential; waterless dyeing offers significant water conservation and is widely used.

[0003] A Chinese patent application (or patent) with publication number CN217629058U discloses a waterless dyeing device for low-carbon textile dyeing and finishing, including a waterless dyeing furnace body. A box is connected to one side of the top of the waterless dyeing furnace body, and a conduit is connected to one side of the outer wall of the box. A dust collection box is slidably connected inside the box, and a negative pressure fan is embedded in one side of the outer wall of the dust collection box. The dust collection box includes a top cover, a bottom frame, a filter plate, a handrail, and perforations. A perforation is provided on one side of the outer wall of the bottom frame.

[0004] However, the above-mentioned device still has the following problems during implementation: In the dyeing process of textiles, negative pressure adsorption is used to clean the surface dust to ensure the purity of dyeing. However, the fabric is prone to wrinkles due to uneven tension or compression during the conveying and stacking process. If it is directly sent to the waterless dyeing furnace for dyeing, the fabric will be tightly attached at the wrinkles, making it difficult for air to circulate and hindering the transfer. This can easily lead to local accumulation, resulting in uneven dyeing, color deviation, and affecting the quality of the finished product.

[0005] To address this issue, we provide a double-sided flannel waterless dyeing apparatus. Summary of the Invention

[0006] The purpose of this invention is to provide a double-sided flannel waterless dyeing device. Through the structural cooperation of the stretching component, the driving component and the preheating component, it solves the problem of current waterless dyeing equipment for textiles. While the dust on the surface of the textile is cleaned and filtered by negative pressure, the textile is prone to wrinkles during the conveying and stacking process. When it is directly put into the waterless dyeing furnace for combustion, uneven dyeing is likely to occur.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a double-sided flannel waterless dyeing device, comprising a detection shell, inside which is a guide rail disk. Two sets of take-up rollers are arranged on one side of the guide rail disk, and an adjusting frame is located at the bottom of each take-up roller. A dyeing roller is movably connected inside the adjusting frame, and a dyeing strip is fitted onto the surface of each dyeing roller. A stretching assembly is arranged on one side of the guide rail disk. The stretching assembly includes a roller motor disposed inside the take-up rollers, a pressure sensor mounted on the surface of the roller motor, movable shafts mounted on both output ends of the roller motor, a guide rail groove formed inside the guide rail disk, a guide rail plate slidably connected to the surface of the movable shafts, and a drive shaft mounted on one side of the guide rail plate. The stretching assembly stretches the wrinkled fabric. A [further details about the device are missing from the original text.] The drive assembly includes a connecting column installed between two sets of guide rails, a rotating shaft movably connected inside the connecting column, a first sprocket mounted on the surface of the rotating shaft, a second sprocket mounted on the surface of the drive shaft, and a first chain meshing with the surfaces of the first and second sprockets. The drive assembly provides driving force to the stretching assembly. A preheating assembly is provided on one side of the detection housing. The preheating assembly includes a fixed pipe installed between the two sets of guide rails, an air outlet pipe connected to one side of the fixed pipe, a heating fan located on one side of the detection housing, and a connecting pipe connected to the air outlet on one side of the heating fan. The preheating assembly preheats the textile fabric. A filter assembly is provided inside the detection housing to filter impurities generated during dyeing.

[0009] The present invention is further configured such that the movable shaft is slidably connected to the inside of the guide rail groove, a slider is fixedly connected to the surface of the movable shaft, and the slider is slidably connected to the inner wall of the guide rail plate.

[0010] The present invention is further configured such that the driving assembly also includes a driving motor mounted on one side of the guide rail disk, and the output end of the driving motor is fixedly connected to the rotating shaft.

[0011] The present invention is further configured such that the other end of the connecting pipe is connected to the fixed pipe, and an exhaust port is provided on one side of the detection shell.

[0012] The present invention is further configured such that the filtration assembly includes a servo motor installed inside the adjustment frame, an auxiliary roller movably connected inside the adjustment frame, a third sprocket installed on the surface of the dyeing roller, a fourth sprocket installed on the surface of the auxiliary roller, a collection shell installed on one side of the adjustment frame, drain ports opened on both sides of the collection shell, and a filter cylinder disposed inside the collection shell.

[0013] The present invention is further configured such that a mounting shaft is fixedly connected to the bottom of the filter cylinder, a first bevel gear is mounted on the surface of the mounting shaft, a second bevel gear meshes with one side of the first bevel gear, a fixed shaft is mounted at the center of the second bevel gear, a fifth sprocket is mounted on the surface of the fixed shaft, and a second chain meshes with the surfaces of the third sprocket, the fourth sprocket and the fifth sprocket.

[0014] The present invention is further configured such that a guide shell is provided at the top of the filter cylinder, both sides of the guide shell are fixedly connected to the inner wall of the collection shell, and the output end of the servo motor is fixedly connected to the dyeing roller.

[0015] The present invention is further configured such that a rubber scraper is fixedly connected to the top of the collection shell, and one side of the rubber scraper is in contact with the dyeing belt.

[0016] The present invention is further configured such that a guide groove is slidably connected inside the adjusting frame, a squeezing roller is slidably connected inside the guide groove, and a first spring is fixedly connected inside the guide groove.

[0017] The present invention is further configured such that support rods are fixedly connected to both sides of the adjustment frame, and a support column is slidably connected to the surface of the support rod. One side of the support column is fixedly connected to the inner wall of the detection shell, and a second spring is installed inside the support column.

[0018] The present invention has the following beneficial effects: By setting up a stretching component, a driving component, and a preheating component, and utilizing the roller motor and pressure sensor installed inside the take-up roller, along with the guide rail groove and guide rail plate, the present invention can monitor the tension in real time and automatically adjust the stroke of the moving shaft during the fabric circulation conveying process, so that the two sets of take-up rollers move in opposite directions to perform directional stretching and flattening of the wrinkled area. The driving motor transmits power synchronously to the driving shaft through the sprocket and chain to ensure coordinated and stable stretching action. The heating fan preheats and softens the fabric through the fixed pipe and the air outlet pipe to avoid breakage caused by low-temperature brittle stretching. The filtering component uses the rotation of the dyeing roller to drive the centrifugal rotation of the filter cylinder to perform real-time solid-liquid separation of the scraped dye, realizing the recycling of dye.

[0036] Specifically: The drive shaft 706 is mounted on one side of the guide rail plate 705 to drive the guide rail plate 705 to rotate, thereby pushing the moving shaft 703 to slide along the guide rail groove 704 to complete the stretching action. The connecting column 801 is installed between the two sets of guide rail discs 2 to fix the rotating shaft 802 and enhance the overall structural rigidity of the guide rail discs 2. The rotating shaft 802 is movably connected inside the connecting column 801 to transmit the rotational power of the drive motor 806 to the first sprocket 803. The first sprocket 803 is mounted on the surface of the rotating shaft 802 to drive... The first chain 805 rotates, and the second sprocket 804 is mounted on the surface of the drive shaft 706 to receive the power transmitted by the first chain 805 and drive the drive shaft 706 to rotate. The first chain 805 meshes with the surfaces of the first sprocket 803 and the second sprocket 804 to transmit power from the first sprocket 803 to the second sprocket 804. The drive motor 806 is mounted on one side of the guide rail disk 2, and its output end is fixedly connected to the rotating shaft 802 to provide stable and continuous rotational power for the entire drive assembly 8. The fixed tube 901 is installed on both sets of... Between the guide rails 2, the air outlet duct 902 is connected to form a hot air delivery channel, ensuring that the hot air is evenly distributed to the fabric surface. The air outlet duct 902 is connected to one side of the fixed pipe 901 to direct the heated air towards the textile fabric for local preheating. The heating fan 903 is located on one side of the detection housing 1 to generate a high-temperature airflow. The connecting pipe 904 connects the air outlet of the heating fan 903 to the fixed pipe 901 to stably deliver the hot air into the fixed pipe 901, forming a complete hot air circulation path. The exhaust port is opened. On one side of the detection housing 1, it is used to discharge excess hot and humid air generated during the preheating process and maintain the air pressure balance inside the device. The auxiliary roller 1020 is movably connected inside the adjustment frame 4 to support the dyeing belt 6 and guide it to run smoothly, preventing the dyeing belt 6 from deviating or slipping. The third sprocket 1030 is installed on the surface of the dyeing roller 5 to output the power of the servo motor 1010 to the second chain 17. The fourth sprocket 1040 is installed on the surface of the auxiliary roller 1020 to maintain the tension of the second chain 17 and assist in transmitting power.

[0037] Example 3: Please refer to Figures 1-10 Based on Embodiments 1 and 2, a guide shell 18 is provided on the top of the filter cylinder 1070. Both sides of the guide shell 18 are fixedly connected to the inner wall of the collection shell 1050. The output end of the servo motor 1010 is fixedly connected to the dyeing roller 5. A rubber scraper 19 is fixedly connected to the top of the collection shell 1050. One side of the rubber scraper 19 is in contact with the dyeing belt 6. A guide groove 20 is slidably connected inside the adjusting frame 4. A squeezing roller 21 is slidably connected inside the guide groove 20.

A second spring 25 is installed inside the support column 24.

[0038] Specifically: The fifth sprocket 16 is mounted on the surface of the fixed shaft 15 to receive the power of the second chain 17 and drive the filter cylinder 1070 to rotate. The second chain 17 meshes with the surfaces of the third sprocket 1030, the fourth sprocket 1040, and the fifth sprocket 16 to synchronously transmit the power of the servo motor 1010 to the dyeing roller 5, the auxiliary roller 1020, and the filter cylinder 1070. The collection shell 1050 is mounted on one side of the adjusting frame 4 to receive the dyeing agent and impurities scraped off the surface of the dyeing belt 6 by the rubber scraper 19. The drain port 1060 is opened on both sides of the collection shell 1050 to discharge the cleaned dyeing agent after centrifugal filtration, facilitating recycling. The filter cylinder 1070 is located inside the collection shell 1050 and rotates at high speed. Centrifugal force is generated to accelerate the separation process of dye and impurities. The mounting shaft 12 is fixedly connected to the bottom of the filter cylinder 1070 to support the filter cylinder 1070 and transmit rotational power. The first bevel gear 13 is mounted on the surface of the mounting shaft 12 and meshes with the second bevel gear 14 to convert horizontal rotation into vertical rotation. The second bevel gear 14 meshes with one side of the first bevel gear 13 and is mounted on the surface of the fixed shaft 15 to transmit the rotation of the fixed shaft 15 to the mounting shaft 12. The fixed shaft 15 is mounted at the axis of the second bevel gear 14 to fix the fifth sprocket 16 and transmit power to the second bevel gear 14. The guide shell 18 is located at the top of the filter cylinder 1070 and is fixedly connected to the inner wall of the collection shell 1050 on both sides to guide... The scraped-off dye and impurities smoothly enter the filter cartridge 1070. A rubber scraper 19 is fixedly connected to the top of the collection shell 1050, with one side in close contact with the surface of the dyeing belt 6. This scrapes away residual dye and adhering substances from the surface of the dyeing belt 6 in real time, keeping it clean and improving transfer uniformity. A slider 11 is fixedly connected to the surface of the moving shaft 703 and slidably connected to the inner wall of the guide rail plate 705, allowing the moving shaft 703 to slide flexibly within the guide rail plate 705 to adapt to changes in the path of the guide rail groove 704. A guide groove 20 is slidably connected inside the adjusting frame 4 to accommodate the squeeze roller 21 and restrict its movement direction. The squeeze roller 21 is slidably connected inside the guide groove 20 to adjust the contact pressure between the dyeing belt 6 and the textile fabric. To ensure close contact between the fabric and the dyeing belt 6 during the transfer process, the first spring 22 is fixedly connected inside the guide groove 20, with one end abutting against the extrusion roller 21 to provide elastic restoring force to the extrusion roller 21, keeping the contact pressure constant. The support rod 23 is fixedly connected to both sides of the adjustment frame 4 to connect the adjustment frame 4 and the support column 24, realizing the overall lifting and lowering adjustment of the adjustment frame 4. The support column 24 is slidably connected to the surface of the support rod 23, with one side fixedly connected to the inner wall of the detection shell 1 to provide stable vertical support for the adjustment frame 4. The second spring 25 is installed inside the support column 24 and sleeved on the surface of the support rod 23 to apply a continuous elastic thrust to the adjustment frame 4, so that it can automatically reset after being subjected to force, maintaining stable contact between the dyeing roller 5 and the textile fabric.

[0039] The working principle of this invention is as follows: the worker wraps and fixes the textile fabric to be processed onto the surfaces of two sets of take-up rollers 3, such as... Figure 1 As shown, the roller motor 701 is then started by the external controller. The two roller motors 701 rotate in the same direction, causing the textile fabric on the surface of the take-up roller 3 to be circulated and conveyed. During the circulation conveying of the textile fabric, the heating fan 903 is started. The heating fan 903 sends hot air into the connecting pipe 904, and blows the hot air onto the textile fabric through the fixed pipe 901 and the air outlet pipe 902 to preheat the textile fabric and prevent the wrinkled textile fabric from breaking during the stretching process.

[0040] Then, the drive motor 806 is started. The drive motor 806, together with the rotating shaft 802, drives the first sprocket 803 to rotate. The first sprocket 803, together with the first chain 805, drives the second sprocket 804 to rotate. The second sprocket 804, together with the drive shaft 706, drives the guide plate 705 to rotate. The guide plate 705 pushes the moving shaft 703 to slide inside the guide groove 704. When the two sets of moving shafts 703 rotate to a horizontal state inside the guide groove 704, the guide groove 704 is elliptical in design, which can guide the two sets of moving shafts 703 to move in opposite directions. The moving shaft 703, together with the roller motor 701, drives the pressure sensor 702 to move. The pressure sensor 702 drives the take-up roller 3 and the textile fabric to move, stretching the textile fabric, smoothing out the wrinkles, and improving the dyeing effect of the textile fabric.

[0041] The detection shell 1 contains dye. Then, the servo motor 1010 is started. The servo motor 1010, together with the dyeing roller 5, drives the dyeing belt 6 to rotate. The dyeing belt 6 guides the dye upward. When the drive motor 806 drives the textile fabric to return to a vertical state, the textile fabric can contact the dyeing belt 6. When the textile fabric and the dyeing belt 6 rotate relative to each other, the dye on the surface of the dyeing belt 6 can be transferred to the surface of the textile fabric, thus achieving waterless dyeing.

[0042] When the dyeing agent is circulated and conveyed on the surface of the dyeing belt 6, the dyeing belt 6 comes into contact with the rubber scraper 19. The rubber scraper 19 scrapes off the dyeing agent and impurities and guides them into the filter cylinder 1070 through the guide shell 18. When the dyeing roller 5 rotates, it can drive the third sprocket 1030 to rotate. The third sprocket 1030, together with the second chain 17, drives the fifth sprocket 16 to rotate. The fifth sprocket 16, together with the fixed shaft 15, drives the second bevel gear 14 to rotate. The second bevel gear 14, together with the first bevel gear 13, drives the mounting shaft 12 to rotate. The mounting shaft 12 drives the filter cylinder 1070 to rotate. The centrifugal force accelerates the filtration of the dyeing agent and facilitates the recycling of the dyeing agent.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
