Description

Technical Field

[0001] This application relates to the field of desizing machines, and more particularly to a fabric feeding device for a desizing machine. Background Technology

[0002] The development of one-bath blended dyeing technology is a key focus in the textile printing and dyeing industry. This process can dye multi-fiber blended fabrics in a single dye bath, eliminating the need for separate baths. This significantly shortens the production cycle, reduces water and chemical raw material consumption, and improves the dyeing uniformity of blended fabrics, meeting the industry's demands for energy conservation, environmental protection, and high-efficiency production. Desizing, a crucial pre-process in the one-bath blended dyeing process, is primarily used to remove sizing agents adhering to the fabric during weaving. The desizing machine is the key equipment for this process, removing sizing agents from the fabric surface to provide a clean fabric base for subsequent dyeing processes.

[0003] Currently, the fabric feeding device of a desizing machine, as a core component in the front end of the desizing machine, mainly guides the fabric smoothly into the desizing machine body through guide rollers, ensuring smooth feeding and stable fabric tension. Existing desizing machine fabric feeding devices typically only include a frame and guide rollers. The guide rollers are rotatably connected to the frame, and the fabric adheres to the surface of the guide rollers to complete the guidance.

[0004] Regarding the aforementioned technologies, before the fabric enters the desizing machine, its surface easily carries impurities such as lint and dust. Furthermore, some residual sizing material from the fabric transfers to the surface of the guide rollers, where it easily adheres and forms dried deposits. As the guide rollers continue to rotate, these deposits repeatedly transfer to the surface of subsequent fabrics, contaminating the fabric and causing problems such as stains and uneven sizing residue, thus affecting fabric quality. Summary of the Invention

[0005] In order to reduce impurities on the surface of the guide roller and improve the quality of the fabric, this application provides a fabric feeding device for a desizing machine.

[0006] The fabric feeding device for a desizing machine provided in this application adopts the following technical solution: A fabric feeding device for a desizing machine includes a frame and a guide roller. The frame is connected to the desizing machine body, and the guide roller is rotatably connected to the frame. The frame is connected to a scraper and a dust collection hood. The dust collection hood has a dust collection hole at one end near the guide roller. The dust collection hood is connected to an air extraction component, which is used to extract air into the dust collection hood to create a negative pressure inside the dust collection hood. The scraper is connected to the end of the dust collection hood near the guide roller and is used to guide impurities into the dust collection hood.

[0007] By adopting the above technical solution, during use, when the guide roller rotates, the scraper adheres to its surface and scrapes away the attached impurities and dried slurry. The scraped-off attachments are guided by the scraper towards the dust collection hood. The air extraction component works to create negative pressure inside the dust collection hood, and the scraped-off attachments are sucked in and collected in time through the dust collection holes, thereby reducing the attachments on the surface of the guide roller, minimizing the transfer of impurities to the fabric surface, and improving the fabric quality.

[0008] Optionally, a cleaning roller is rotatably connected to the frame. The cleaning roller includes a first sponge layer for contacting the guide roller. A rotating assembly is connected to the frame for driving the cleaning roller to rotate. A water outlet pipe is connected to the frame. One end of the water outlet pipe is connected to a liquid supply source. Several nozzles are connected to the water outlet pipe, and the water outlet of each nozzle faces the first sponge layer.

[0009] By adopting the above technical solution, during use, water is supplied to the nozzle through the water outlet pipe, and the nozzle sprays water onto the first sponge layer to keep it moist. The moist sponge layer can enhance the ability to dissolve and wipe the dried slurry, thereby facilitating the cleaning of the slurry by the scraper, further reducing the slurry on the surface of the guide roller, and improving the quality of the fabric.

[0010] Optionally, the frame is connected to a collection box with an opening at the top, and the collection box is connected to a squeezing roller that contacts the first sponge layer.

[0011] By adopting the above technical solution, during use, the first sponge layer comes into contact with the squeezing roller during the rotation of the cleaning roller. The squeezing roller squeezes and dehydrates the sponge layer, and the squeezed-out wastewater falls into the collection box below for centralized collection, so as to avoid the wastewater dripping onto the fabric or equipment and causing secondary pollution. At the same time, the dehydrated sponge layer can quickly absorb the clean water sprayed from the nozzle and maintain a continuously moist and clean state, realizing the cycle of cleaning, dehydration and water replenishment.

[0012] Optionally, a support plate is connected to the top of the collection box, and the cleaning roller also includes a disc. Two discs are provided, and the two ends of the first sponge layer are respectively connected to the two discs. The discs are rotatably connected to the support plate. The rotating assembly includes a first gear, a second gear, and a first motor. The first gear is connected to the disc, the first motor is connected to the support plate, and the output shaft of the first motor is connected to the second gear. The second gear meshes with the first gear.

[0013] By adopting the above technical solution, when in use, the first motor starts and drives the second gear to rotate. Through gear meshing, the first gear and the disc rotate, thereby driving the cleaning roller to rotate stably as a whole, which facilitates the rotation of the cleaning roller and the cleaning of the guide roller.

[0014] Optionally, the first sponge layer is connected to an installation block, the disc has an installation groove, the installation block is inserted into the disc through the installation groove, and the installation block is detachably connected to the disc by bolts.

[0015] By adopting the above technical solution, when the first sponge layer becomes worn, aged, or clogged due to long-term use, the bolts can be removed to take the mounting block out of the mounting groove, realizing the quick replacement of the first sponge layer without disassembling the entire cleaning roller, simplifying the maintenance process and reducing maintenance costs.

[0016] Optionally, the collection box is connected to a slider, which slides and engages with the frame. The frame is connected to a pusher, which drives the slider to move and pushes the first sponge layer closer to the guide roller.

[0017] By adopting the above technical solution, during use, the pusher can drive the slider to slide along the frame, thereby driving the collection box and cleaning roller to move as a whole, so that the first sponge layer is pressed against the periphery of the guide roller, thereby improving the cleaning effect of the cleaning roller on the guide roller. At the same time, when replacing the sponge layer, the pusher can drive the cleaning roller away from the guide roller, providing sufficient operating space and improving maintenance convenience.

[0018] Optionally, the frame has a sliding hole, the slider slides and engages with the inner wall of the sliding hole, the pushing component is a first cylinder, the first cylinder is connected to the frame, and the piston rod of the first cylinder is connected to the slider.

[0019] By adopting the above technical solution, when in use, the first cylinder drives the piston rod to extend and retract, causing the slider to slide smoothly along the moving hole. The moving hole provides guidance and limit for the slider, minimizing deviation during the sliding process.

[0020] Optionally, the extrusion roller slides against the inner wall of the collection box, and a first spring is connected to the inner wall of the collection box. One end of the first spring is connected to the extrusion roller, and the other end of the first spring is connected to the inner wall of the collection box. The first spring is used to drive the extrusion roller to move and drive the extrusion roller to approach the first sponge layer.

[0021] By adopting the above technical solution, the elastic force of the first spring continuously drives the extrusion roller to adhere to the first sponge layer, thereby improving the dehydration effect. At the same time, the elastic extrusion can minimize the damage to the sponge layer caused by excessive pressure, extend the service life of the sponge layer, and improve the adaptability and stability of the extrusion structure.

[0022] Optionally, the frame is rotatably connected to a water-absorbing roller, the water-absorbing roller including a second sponge layer, the second sponge layer being in contact with the periphery of the guide roller, and the cleaning roller, scraper, and water-absorbing roller being distributed sequentially along the rotation direction of the guide roller.

[0023] By adopting the above technical solution, when the guide roller rotates, most of the attached substances are first removed by the cleaning roller wet wiping, then scraped by the scraper, and the dust suction hood absorbs and removes residual impurities and sewage. Finally, the second sponge layer of the water suction roller absorbs the residual moisture on the surface of the guide roller, realizing the whole process of wiping-scraping-absorption-water absorption, so that the surface of the guide roller is dry and clean, and moisture is avoided as much as possible from being transferred to the fabric and affecting the desizing effect.

[0024] Optionally, the frame is connected to a water collection tank, the top of which is open, and a squeezing roller is connected to the water collection tank, the squeezing roller contacting the second sponge layer.

[0025] By adopting the above technical solution, during use, the squeezing roller squeezes the second sponge layer, thereby squeezing the water in the second sponge layer into the water collection tank, thereby reducing the water in the second sponge layer and improving the water absorption effect of the second sponge layer on the guide roller.

[0026] In summary, this application includes at least one of the following beneficial technical effects: During use, as the guide roller rotates, the scraper adheres to its surface and scrapes away the adhering impurities and dried slurry. The scraped-off material is guided by the scraper towards the dust collection hood. The air extraction component works to create negative pressure inside the dust collection hood, and the scraped-off material is sucked in and collected in time through the dust collection holes. This reduces the amount of material adhering to the surface of the guide roller, minimizes the transfer of impurities to the fabric surface, and improves the quality of the fabric. During use, as the cleaning roller rotates, the first sponge layer comes into contact with the squeezing roller. The squeezing roller squeezes and dehydrates the sponge layer, and the squeezed-out wastewater falls into the collection box below for centralized collection, minimizing the risk of wastewater dripping onto the fabric or equipment and causing secondary pollution. At the same time, the dehydrated sponge layer can quickly absorb the clean water sprayed from the nozzle, continuously maintaining a moist and clean state, thus achieving a cycle of cleaning, dehydration, and water replenishment. During use, the pusher can drive the slider to slide along the frame, thereby moving the collection box and cleaning roller as a whole, so that the first sponge layer is pressed against the periphery of the guide roller, thereby improving the cleaning effect of the cleaning roller on the guide roller. At the same time, when replacing the sponge layer, the pusher can drive the cleaning roller away from the guide roller, providing sufficient operating space and improving maintenance convenience.

[0048] The implementation principle of the fabric feeding device of the desizing machine in this embodiment is as follows: During use, the desizing machine and the fabric feeding device are turned on, and the guide roller 110 begins to rotate, guiding the fabric into the desizing machine body. During the rotation of the guide roller 110, water is supplied to the nozzle 241 through the water outlet pipe 240.

[0049] The scraper 300 adheres to the surface of the guide roller 110, scraping away impurities and dried slurry. The scraped-off impurities are guided towards the dust collection hood 310, and under the negative pressure inside the dust collection hood 310, they are sucked into the dust collection hood 310 through the dust collection holes 311 and collected in the connecting box 324. As the guide roller 110 continues to rotate, when it passes the water absorption roller 400, the second sponge 420 layer of the water absorption roller 400 absorbs the residual moisture on the surface of the guide roller 110, keeping the surface of the guide roller 110 dry and clean, and preventing moisture from transferring to the fabric and affecting the desizing effect.
