Description

Technical Field

[0001] The utility model relates to the technical field of web laying machines, in particular to a negative pressure suction device for a web laying machine. Background Art

[0002] Fiber web laying machines are divided into short-fiber carding web laying machines and long-fiber spunbond web laying machines. Long-fiber spunbond web laying machines can be further divided into web laying machines for needling, hot rolling, and hydroentanglement processes. Spunbond needle-punch web laying machines generally have widths of 2.4 meters, 3.5 meters, 4.5 meters, and 6.8 meters, with a maximum web laying speed of around 20 meters per minute and a web weight of around 80 to 600 g / m². After the web laying machine has been running for a long time, these fine cotton fibers will clog the web laying machine's pressure rollers, guide rollers, and other mechanical components, causing the web laying machine to malfunction, affecting production efficiency and progress. Therefore, a negative pressure suction device is required.

[0003] However, in the process of using the existing negative pressure suction device, in order to prevent the fluff from entering the interior of the negative pressure fan, a filter plate is usually used to block it to prevent the fluff from entering and damaging its internal parts. However, after long-term use of the filter plate, the surface is prone to absorb the fluff. If it is not cleaned in time, the fluff will clog the filter holes of the filter plate over time, thereby affecting the absorption of suction and causing trouble to the staff. For this reason, we propose a negative pressure suction device for a net laying machine to solve the above problem. Utility Model Content
