Description

Technical Field

[0001] This utility model relates to the field of fabric processing equipment technology, and in particular to a fabric dyeing and drying machine. Background Technology

[0002] When dyeing fabrics, the fabric to be dyed is usually placed in a dyeing vat for dyeing. After dyeing, the fabric is taken out of the dye liquid in the vat and then dried using a dryer.

[0003] A search revealed a Chinese patent with publication number CN202220635025.9, which discloses a dryer for dyeing knitted fabrics. By improving and optimizing the structure of the fabric dyeing dryer, the hopper can filter water from the fabric entering the dryer, removing some of the water from within the fabric. This prevents a large amount of water from spilling onto the workshop floor when the fabric exits the hopper. Furthermore, this dryer hopper is flexible, convenient, and easy to operate. The improved and optimized hopper structure divides the hopper into two spaces, facilitating both fabric storage and water filtration during discharge. This prevents a large amount of water from spilling onto the floor. The improved and optimized filter head structure allows it to be installed at the top of the hopper, facilitating scraping water from the fabric during discharge and ensuring that some moisture is scraped out, preventing water from spilling out of the hopper with the fabric.

[0004] The above-mentioned technical solution has the following drawbacks. Although such a dyeing and drying machine structure can scrape the dye out of the fabric through an elastic pressure plate, and the scraped dye can be discharged from the water storage chamber at regular intervals, in actual use, the dye squeezed out of the fabric can be reused. In order to further reduce resource consumption and improve the utilization rate of dye, a fabric dyeing and drying machine is proposed. It can perform dyeing, dehydration and drying of the fabric in one integrated process, and can collect and filter the removed dye during the dehydration and drying process, so that the removed dye can be reused, saving resources. It is equipped with a scraper to scrape and clean both sides of the fabric, so that the stains and threads on the surface of the fabric can be scraped off and collected, thereby improving the quality of the finished fabric.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a fabric dyeing and drying machine that solves the problems mentioned in the background. It can perform dyeing, dehydration and drying of fabric in one process, and can collect and filter the removed dye during the dehydration and drying process, so that the removed dye can be reused, saving resources. It is equipped with a scraper to scrape and clean both sides of the fabric, so that stains and loose threads on the surface of the fabric can be scraped off and collected, thereby improving the quality of the finished fabric.

[0008] The solution to the above-mentioned technical problems of this utility model is as follows: A fabric dyeing and drying machine includes a main body and a fabric conveying frame. Two partition plates are fixedly installed on the inner wall of the main body. The inner wall of the main body is divided into a drying chamber, a dehydration chamber, and a dyeing chamber by the partition plates. Material inlets are provided on both sides of the main body and on the partition plates. Four fabric conveying frames are provided, each with its own inner wall connected to one of the four material inlets. Conveying rollers are rotatably connected to the inner wall of each fabric conveying frame. A servo motor is fixedly installed on the inner wall of each set of fabric conveying frames. The drive end of the servo motor is fixedly connected to one side of the conveying roller. An air inlet is fixedly connected to the drying chamber. A fan and an electric heater are fixedly installed on the inner wall of the air inlet. The drying chamber and the dehydration chamber... A first guide roller is uniformly and rotatably connected to the inner wall of the dyeing chamber. A second guide roller is uniformly and rotatably connected to the inner wall of the dyeing chamber. A filter screen is installed on the inner wall of the dehydration chamber by screws. A squeeze roller is rotatably connected to the inner wall of the dehydration chamber. There are two sets of squeeze rollers, each set containing two rollers. A scraper is installed on the inner wall of the squeeze roller by screws. There are two sets of scrapers, each set containing two scrapers. A dye delivery pipe is fixedly connected to the top of the dyeing chamber. There are two dye delivery pipes. Drain valves are fixedly connected to the bottom of both the dehydration chamber and the dyeing chamber. A delivery pump is fixedly connected to the top of the main body of the machine. One end of the delivery pump is connected to the drain valve at the bottom of the dehydration chamber, and the other end is connected to the dye delivery pipe on one side. A guide block is fixedly installed on the inner wall of the dehydration chamber.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, each set of fabric conveying frames is equipped with two conveying rollers, and each conveying roller is fixedly connected to a transmission gear. The transmission gears on both sides are meshed together, and the transmission gears on both sides of the conveying rollers are meshed together, so that when the servo motor rotates one conveying roller, it can drive the other conveying roller to rotate synchronously, thereby driving the fabric to be conveyed in the main body of the machine.

[0011] Furthermore, multiple sets of servo motors are connected to the same servo controller, enabling the multiple sets of servo motors to rotate the conveyor rollers synchronously, thereby driving the fabric to be conveyed within the main body of the machine.

[0012] Furthermore, exhaust vents are provided on both sides of the drying chamber, and dustproof nets are fixedly installed on the inner walls of the exhaust vents. The drying air can be discharged from the dustproof nets of the exhaust vents, allowing the drying air to circulate in the drying chamber to quickly dry the internal fabrics. The dustproof nets can prevent external dust from entering.

[0013] Furthermore, a guide plate is fixedly installed on the inner wall of the drying chamber, and a return hole is opened on one side of the partition plate corresponding to the guide plate, so that the dye collected in the drying chamber can flow back to the dehydration chamber through the return hole under the guiding action of the guide plate for subsequent reuse.

[0014] Furthermore, a dust filter screen is fixedly installed on the inner wall of the air inlet cylinder to prevent external dust from entering the main body of the casing.

[0015] Furthermore, a sealing door is provided on the outer wall of the main body of the chassis corresponding to the filter screen. Opening the sealing door allows the filter screen to be removed from the main body of the chassis, thereby processing the filtered fabric residue and thread ends.

[0016] Furthermore, the top of the guide block is set with an arc-shaped structure, and one end of the scraper is set with an arc-shaped structure. The scraper can smoothly fit against the fabric surface to scrape off the residue and thread ends. The fabric residue and dye liquid scraped off by the two inner scrapers can slide down on both sides of the guide block, thereby preventing the scraped fabric residue and dye liquid from contaminating the bottom fabric.

[0017] This utility model provides a fabric dyeing and drying machine, which has the following advantages:

[0018] 1. Multiple servo motors can be driven to rotate by the same servo controller. The servo motors can drive the conveyor rollers in the fabric conveyor frame to rotate and thus convey the fabric. The fabric passes through the conveyor roller on one side of the fabric conveyor frame into the dyeing chamber, bypasses multiple sets of No. 2 guide rollers and is then conveyed to the dewatering chamber. Under the guidance of the No. 1 guide roller in the dewatering chamber, the fabric bends and passes through the scraper and extrusion rollers and is then conveyed to the drying chamber. Under the guidance of the No. 1 guide roller, the fabric bends and passes through the drying chamber and then exits from the main body of the machine box through the conveyor roller on the other side. Thus, dyeing, dewatering and drying can be integrated into one process.

[0019] 2. Dye can be supplied to the dyeing chamber through the dye delivery pipe. The fabric that bends through the dyeing chamber can be dyed. After the dyed fabric is transferred to the dehydration chamber, multiple sets of scrapers can scrape both sides of the dyed fabric, so that the fabric residue on the outer wall of the fabric can be scraped off. The squeeze roller can squeeze and dehydrate the dyed fabric. When the squeezed dye liquid and fabric residue pass through the filter screen, the fabric residue can be collected in the filter screen, and the dye liquid can pass through the guide plate and be collected at the bottom of the inner wall of the dehydration chamber. Open the drain valve at the bottom of the dehydration chamber and start the delivery pump to pump the dye collected in the dehydration chamber into the dyeing chamber for reuse.

[0020] 3. After the dehydrated and cleaned dyed fabric is transferred to the drying chamber, the fan can introduce air from the outer wall, the electric heater can heat the introduced air, and the drying air can dry the dyed fabric in the drying chamber. The dyeing agent dripping during the drying process can be flowed from the guide plate through the return hole into the dehydration chamber for reuse.

[0021] 4. This fabric dyeing and drying machine can perform dyeing, dehydration and drying of fabric in one process. It can also collect and filter the removed dye during the dehydration and drying process, so that the removed dye can be reused, saving resources. It is equipped with a scraper to scrape and clean both sides of the fabric, so that stains and loose threads on the fabric surface can be scraped off and collected, thereby improving the quality of the finished fabric.
