Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric processing, in particular to a ramie carding and belting machine utilizing the water spunlace principle. Background Art

[0002] The spunlace principle is commonly used in the processing of non-woven fabrics. By spraying high-pressure fine water flow onto one or more layers of fiber webs, the fibers are entangled with each other, thereby strengthening the fiber web and giving it a certain strength. The resulting fabric is a spunlace non-woven fabric.

[0003] A large amount of water resources are required in the processing of spunlace non-woven fabrics. Therefore, in order to save water resources, common spunlace non-woven fabric processing generally uses circulating water for processing. After the water is sprayed onto the ramie fiber, it is collected by the water storage tank at the bottom and circulated back to the spraying equipment. However, due to the messy and slender characteristics of the fibers themselves, the recycled water often contains fiber impurities. Over time, these fiber impurities will clog the water circulation system, interfere with the continuous operation of the equipment, and require manual cleaning, affecting the processing efficiency of the non-woven fabric.

[0004] Based on this, the present invention designs a ramie carding and belting machine using the water spunlace principle to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0028] A ramie carding and ribbon-forming machine using the hydroentanglement principle includes a front mounting frame 1 and a rear mounting frame 4, characterized in that the front mounting frame 1 and the rear mounting frame 4 are arranged in parallel and are both equipped with a hydroentanglement unit, a pulling component is provided between the front mounting frame 1 and the rear mounting frame 4, and a water circulation component is provided on the hydroentanglement unit, the water circulation component including:

[0029] The fiber recovery assembly includes a filter screen 2 and a water trough cover 3. The water trough cover 3 is fixedly mounted on the lower surface of the front mounting frame 1 and the rear mounting frame 4. The filter screen 2 covers the top of the water trough cover 3 and is slidably connected to the water trough cover 3 at both ends through an oscillation unit. The oscillation unit can vibrate the filter screen 2 to concentrate and block the fibers.

[0030] The pumping assembly consists of a suction pump, a suction nozzle and a liquid guide tube group. The suction nozzle and the suction pump are located below the water trough cover 3, and the liquid guide tube group is located above the water trough cover 3 and the lower end is fixedly connected to the suction nozzle.

[0031] In the present invention, the ramie fiber is moved from the front mounting frame to the rear mounting frame for combing treatment, and the high-pressure fine water flow sprayed by the spunlace unit disc is sprayed onto the ramie fiber net. The sprayed water falls naturally under the action of gravity, falls to the bottom through the filter screen and the water tank cover, and is collected. Under the action of the suction pump in the pump suction assembly, it flows back to the spunlace unit from the suction nozzle and the liquid guide tube group, thereby realizing the recycling of the water. During the water circulation process, the filter screen is used to remove the ramie fiber residues falling with the water. Blocking greatly reduces the ramie fibers entering the circulating water tank along with the water body, reducing the possibility of ramie fibers blocking the water circulation system. In the process of blocking the ramie fibers, the filter screen is driven by the oscillation unit to move up and down at both ends, so that the ramie fibers on the filter screen slide down from both sides under the action of vibration and accumulate under the pulling unit, which is convenient for the staff to collect the ramie fibers and avoids the filter screen being blocked by the gradually accumulated ramie fibers, which affects the speed of water circulation.

[0032] The hydroentanglement unit comprises an upper support frame 5, on which are mounted parallel spray assemblies and a material guide assembly. The material guide assembly comprises rotating rollers 21 and positioning rollers 18. Two sets of rotating rollers 21 are provided and are connected to the lower end of the upper support frame 5 for parallel rotation. Positioning roller 18 is fixedly mounted between the two sets of rotating rollers 21. A hydroentanglement slot 19 is vertically defined in the middle of positioning rollers 18. In the present invention, ramie fibers are driven by rotating rollers 21 and, as they pass through positioning rollers 18, water sprayed from the spray assemblies passes through hydroentanglement slots 19, separating the ramie fibers.

[0033] The spray assembly includes a spray tank 6 and a side mounting box 16. The spray tank 6 is provided in multiple groups and is equidistantly mounted on the upper surface of the upper support frame 5. A hose 15 is fixedly connected to the lower end of the upper support frame 5, and a spray nozzle 14 is fixedly mounted on the lower end of the hose 15. The side mounting box 16 is arranged on one side of the spray nozzle 14. Multiple groups of rotating blocks 12 are rotatably mounted on the side mounting box 16. A connecting plate 13 is fixedly mounted on the rotating block 12. The spray nozzle 14 is fixedly connected to the connecting plate 13 and its lower end extends below it. In the present invention, the spray nozzle 14 is fixedly connected to the spray pipe 6 through the hose 15. The hose 15 is a telescopic tube. The upper end of the liquid guide tube group is fixedly connected to the upper end of the spray tank 6. The circulating water enters the spray tank 6 through the liquid guide tube group and is then output from the spray nozzle 14 through the spray tank 6 and the hose 15.

[0034] The upper surface of the side mounting box 16 is fixedly mounted with a connecting block 20, the upper end of which is fixedly mounted with a threaded rod 7, and a transmission member 8 is provided between adjacent threaded rods 7. The transmission member 8 is composed of two sets of transmission wheels and a transmission belt. The transmission wheels are rotatably connected to the upper surface of the upper support frame 5, and the transmission belt is sleeved on the outer side of the transmission wheels. The transmission wheels are threadedly connected to the threaded rod 7. A gear box 22 is fixedly mounted on each of the upper support frames 5. The gear box 22 contains a rotating motor and two sets of mutually meshing transmission gears. The output end of the rotating motor is fixedly connected to one set of transmission gears, and the other set of transmission gears is fixedly connected to the transmission wheel. In the present invention, the height of the spray nozzle 14 can be adjusted by moving the side mounting box 16. The rotating motor drives the mutually meshing transmission gears to rotate, thereby driving the transmission wheel to rotate. Through the interaction between the rotating wheel and the threaded rod 7, the threaded rod 7 is raised and lowered, thereby adjusting the height of the side mounting box 16, and then adjusting the height of the spray nozzle 14, thereby controlling the stamping strength of the spray assembly during the ramie fiber combing process.

[0035] The pulling assembly includes a transition frame 10, which is fixedly mounted between the front mounting frame 1 and the rear mounting frame 4. Upper and lower pressing rollers 9 and 11 are rotatably mounted on the transition frame 10. Two sets of upper pressing rollers 9 are provided, forming an inverted triangular roller set with the lower pressing roller 11. In the present invention, during the ramie fiber combing process, the friction and pressure between the triangularly distributed upper and lower pressing rollers 9 and 11 are used to pull the ramie fibers, ensuring smooth and orderly transmission.

[0036] The oscillation unit includes a pressure sensor and a cylinder 17. The filter screen 2 is fixedly connected to the transition frame 10, and the water tank cover 3 is fixedly mounted with the cylinder 17. The free end of the cylinder 17 is fixedly connected to both ends of the filter screen 2, and the pressure sensor is fixedly mounted on the upper end of the cylinder 17. The pressure sensor is located above the cylinder 17. The present invention can determine the weight of the accumulated fibers on the filter screen 2 by the pressure level of the pressure sensor. The expansion and contraction of the cylinder 17 drives the two ends of the filter screen 2 to move up and down continuously.

[0037] The lower surface of the water tank cover 3 is fixedly connected to the water tank, the water tank cover 3 is densely provided with seepage grooves, and the suction nozzle and the suction pump are at the bottom of the water tank. In the present invention, a small gap is left between the lower surface of the suction nozzle and the bottom of the water tank.

[0038] Among them, the front mounting frame 1, the rear mounting frame 4 and one side of the transition frame 10 are all driven by servo motors, which can drive multiple sets of lower pressure rollers 11, upper pressure rollers 9 and rotating rollers 21 to rotate synchronously. The servo motor drives the lower pressure rollers 11 and the rotating rollers 21 to rotate in the same direction, while the upper pressure rollers 9 and the lower pressure rollers 11 rotate in opposite directions.
