[0002] Fiber felt is a common textile product, usually formed continuously by a production line. Its raw material is short-cut fibers of a certain length. In traditional non-woven production, long fibers need to be chopped first, and then the fibers are transferred to the feeding port of the production line for feeding. Before feeding, the raw material fibers need to be processed to remove internal agglomerations and unevenly aggregated fibers, so as to reduce the fluctuation of fiber feed amount during the feeding process, resulting in unstable product quality.

DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] The following first introduces the embodiments of the present application in conjunction with the accompanying drawings.

[0042] The purpose of the present invention is to solve the problems of uneven fiber chopped length, unstable fiber feeding amount and uneven fiber distribution during feeding in the current production line using chopped fibers as raw materials. At the same time, in the process of converting long fibers into short fibers, there are many process links, high manual participation and low production efficiency. A fiber web tire production line feeding device is provided, which specifically draws out long fibers through a fiber creel, and bundles the dispersed long fibers through a chopped device, a chopped device bundling device and a pressure roller. The chopped device uses a chopped chopper, and the pressure roller transports the fibers forward at a certain frequency to chop the long fibers into short pieces according to the specified length. The chopped fibers fall onto the fiber conveying device through a pipeline, and the fiber loosening device moves forward at a uniform speed, and is finally fed into the feeding end of the carding machine through the airflow, mechanical and vibration dispersion devices arranged on the fiber conveying device. The fiber anti-drop device is installed in the gap below the feeding end of the carding machine, and a fiber collecting device is arranged below it, and the chopped fibers are finally transported back to the production line through a recovery belt.

[0043] The operation process of the device is as follows: the long fiber 12 is drawn out through the fiber creel 11, the fiber enters the bundling device 14 through the pressure roller 13, is introduced into the short cutter, is conveyed forward by the pressure roller, passes through the chopper 15, and the long fiber is cut into short fibers of a certain length. The short fibers pass through the short cut fiber channel 16 and enter the air flow dispersion device. A plurality of air flow channels 25 are arranged in the air flow dispersion device, and an external fan 27 conveys air flow into the device in real time. After the fibers are dispersed, the fibers are sent to the fiber settling chamber 23. When a sufficient amount of fibers are settled, the discharge port 24 is opened, and the fibers are sent to the mechanical dispersion device box 31. After being dispersed for multiple weeks by the fiber dispersion roller 32, the fibers fall at the discharge port 34. When the fibers reach the required amount, the discharge port 34 is opened, and the fibers fall onto the conveyor belt 41. A vibration plate 42 and a weighing device 43 are arranged inside the conveyor belt 41 to transport the fibers forward while dispersing them. The fibers are transported to the feeding end 61 of the production line. The fiber anti-drop device 51 is installed between the fiber conveyor belt 41 and the feeding end 61 of the production line. The upward fine airflow is used to reduce the fibers from falling in the gaps. The dropped fibers generated by the production line 62 during the production process are introduced into the fiber receiving device 53 by the fiber collecting plate 52. The fiber receiving device 53 will monitor the amount of fiber falling in real time and adjust the overall operating speed of the equipment. At the same time, when the amount of dropped fibers reaches a certain amount, the fibers will be sent back to the feeding end 61 of the production line through the fiber recovery belt 54.

[0044] The above-described embodiments of the present application do not constitute a limitation on the protection scope of the present application.
