Filtering mechanism of melt-blown cloth production device

Abstract

The invention relates to a filtering mechanism of a melt-blown cloth production device, which comprises a filter shell and also comprises an operation part and filtering parts, the operation part comprises a T-shaped plate arranged on the filter shell and a first transmission assembly arranged on the T-shaped plate; the number of the filtering parts is two, the filtering parts are arranged on the side face, facing the filter shell, of the T-shaped plate in a telescopic mode, and the two filtering parts are both connected with thetransmission assembly; the transmission assembly is used for driving one filtering part to move in the direction towards the filter shell and driving the other filtering part to move in the direction away from the filter shell; and the replacement mode of a traditional filtering device is improved, the two filtering parts are used for alternate filtering, the filtering parts can be replaced in the running process of the machine, the replacement process can be completed only by manually operating a rotating rod, workers only need to clean and replace the pulled-out filtering parts, the replacement process of the filtering device is accelerated, and the machine does not need to be shut down.

Description

technical field [0001] The invention relates to a filter mechanism of a meltblown cloth production device. Background technique [0002] Melt-blown cloth mainly uses polypropylene as the main raw material. After heating, extrusion, filtration, spinning, netting and electret treatment, the finished melt-blown cloth is formed. It is an indispensable material for masks. It is used in the processing of melt-blown cloth In the process, impurities are easily mixed into the polypropylene raw material. Therefore, in the process of melting it into melt-blown cloth, there are filtering devices to filter out impurities, so as to ensure the melt-blown process of the melt-blown part. However, in the production process of the existing melt-blown cloth, the filter device is usually provided with a filter screen in the housing to achieve the filtering effect. It is inconvenient to replace it, and the filter part needs to be disassembled, and it needs to be shut down for operation. , affect...

Problems solved by technology

However, in the production process of the existing melt-blown cloth, the filter device is usually provided with a filter screen in the shell to achieve the filtering effect. It is inconvenient to replace it, and the filter part needs to be disassembled, and it needs to be shut down for operation. , affecting production efficiency, the replacement efficiency is also low, and the melt blown part needs to be reheated when it is opened again
