Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabric equipment, in particular to a device for cleaning flying waste on the surface of nonwoven materials. Background Art

[0002] In the production process of meltblown nonwoven materials, due to various reasons such as the mismatch between process parameters and raw materials, equipment status, etc., "flying flowers" will appear on the fabric surface, that is, fiber bundles formed by broken fibers. However, in order to ensure the output and product quality, the temperature and flow rate of the hot air flow are generally increased to a higher level, so tiny "flying flowers" will appear. These flying flowers adhere to the surface of the fabric, causing the apparent quality of the product to decrease and reduce the product yield. Summary of the invention

[0003] The object of the present invention is to provide a device for cleaning waste from the surface of nonwoven materials, so as to solve at least one of the above problems existing in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A device for cleaning flying waste on the surface of nonwoven materials comprises a spray system and a collection system. The spray system comprises a nozzle, an air circuit system and a water circuit system. The air circuit system comprises an air compressor, a compressed air dryer, a filter and an air storage tank which are connected in sequence. The air storage tank is connected to the nozzle through an air supply pipe. The water circuit system comprises a raw water tank, a multi-stage filter, a first pump, a clean water tank and a second pump which are connected in sequence. The second pump is connected to the nozzle through a water supply pipe. There are two nozzles which are located below a spinneret hole. The nozzle sprays water mist toward a spinning area. The collection system comprises an air duct and a fan. The inlet end of the air duct is located below a web forming machine. A first mesh plate is provided at the inlet end of the air duct. A collection box is connected to the lower end of the air duct. A second mesh plate is provided at the upper end of the collection box. A filtering device is provided in the air duct. Broken fiber bundles entering the air duct are intercepted by the filtering device and enter the collection box.

[0006] In the present technical solution, during use, there are two nozzles located below the spinneret, and the nozzle sprays water mist toward the spinning area. When flying fibers appear in the spinning area, the broken fiber bundles will be wrapped by the water mist, and due to the influence of their own gravity, they will reach the web-forming machine below before the unbroken fibers, and then through the negative pressure suction of the air duct, the broken fiber bundles pass through the first mesh plate, then pass through the air duct, and finally are intercepted by the filter device and enter the collection box, thereby reducing the "flying fibers" that appear in the production process and improving product quality. In the present technical solution, since the air circuit system includes an air compressor, a compressed air dryer, a filter and an air storage tank connected in sequence, the air storage tank is connected to the nozzle through an air supply pipe, wherein the filter can filter the compressed air generated by the air compressor to ensure the cleanliness of the compressed air. Since the water circuit system includes a raw water tank, a multi-stage filter, a first pump, a clean water tank and a second pump connected in sequence, the second pump is connected to the nozzle through a water supply pipe, and the multi-stage filter can filter water to ensure the cleanliness of the water. The flying fibers and impurities can be separated from the air flow of the air duct by the filter device, and then enter the collection box through the action of their own gravity. This technical solution can reduce the flying fibers in the spinning area, thereby reducing the flying fibers on the surface of the melt-blown nonwoven material and improving the product quality.

[0007] Furthermore, the water pipe and the air pipe are provided with a control water valve and a control air valve respectively, which can adjust the flow of compressed air and water online, and reduce the influence of water mist on spinning. It should be noted that the nozzle can adjust the water pressure and air pressure according to the product to spray water mist during the production process.

[0008] Furthermore, in order to achieve a better filtering effect, the filter includes a primary filter and a secondary filter.

[0009] Furthermore, in order to achieve a better filtering effect, the filtering device includes a first filter plate and a second filter plate.

[0010] Furthermore, in order to better realize the installation of the nozzle, the nozzle is installed on the meltblowing die head through a support frame.

[0011] Furthermore, in order to achieve a more suitable spray range, the horizontal distance between the nozzle and the spinneret hole is 60-150 mm, and the vertical distance between the nozzle and the spinneret hole is 30-50 mm.

[0012] Furthermore, in order to provide a suitable water pressure range, the water pressure of the spray system is 0.01-0.1 MPa.

[0013] Furthermore, in order to provide a suitable air pressure range, the air pressure of the spray system is 0.05-0.7 MPa.

[0014] Furthermore, in order to adjust the nozzle to a suitable position according to product requirements, the distance between the nozzle and the spinneret hole can be adjusted in the horizontal direction X and the vertical direction Y.

[0015] Furthermore, the lower end of the collection box is provided with an opening, which can be opened regularly for cleaning.

[0016] The beneficial effects of the present invention are as follows: in the process of using the technical scheme, there are two nozzles located below the spinneret, and the nozzle sprays water mist toward the spinning area. When flying fibers appear in the spinning area, the broken fiber bundles will be wrapped by the water mist, and due to the influence of their own gravity, they will reach the web-forming machine below before the unbroken fibers, and then through the negative pressure suction of the air duct, the broken fiber bundles pass through the first mesh plate, then pass through the air duct, and finally are intercepted by the filtering device and enter the collection box, thereby reducing the "flying fibers" that appear in the production process and improving the product quality. In the technical scheme, since the air circuit system includes an air compressor, a compressed air dryer, a filter and an air storage tank connected in sequence, the air storage tank is connected to the nozzle through an air supply pipe, wherein the filter can filter the compressed air generated by the air compressor to ensure the cleanliness of the compressed air. Since the water circuit system includes a raw water tank, a multi-stage filter, a first pump, a clean water tank and a second pump connected in sequence, the second pump is connected to the nozzle through a water supply pipe, and the multi-stage filter can filter water to ensure the cleanliness of the water. The flying fibers and impurities can be separated from the air flow of the air duct by the filtering device, and then enter the collection box through the action of their own gravity. This technical solution can reduce the flying fibers in the spinning area, thereby reducing the flying fibers on the surface of the melt-blown nonwoven material and improving the product quality.
