Description
Technical Field

[0002] SMC material, namely sheet molding compound, has the advantages of superior electrical properties, corrosion resistance, light weight, easy and flexible engineering design, etc. Its mechanical properties are comparable to those of some metal materials, so it is widely used in transportation vehicles, construction, electronics, electrical and other industries; At present, during the processing of SMC material in SMC sheet forming machine, it is necessary to cut the glass fiber into a certain length by a cutting machine and lay it on the lower raw material paste, and then press it in the middle by the upper and lower raw material paste layers. After extrusion, the glass fiber is fully infiltrated to form SMC sheet, in which the glass fiber plays a role in enhancing the strength of the sheet. When the glass fiber is uniformly doped in the sheet in a certain proportion, the mechanical strength of the molded sheet will be greatly improved. The SMC sheet machine has the problem of short-cutting glass fiber because the glass fiber itself is light in weight and small in size. When it is scattered, it is easy to be scattered outside the processing area. In order to reduce resource waste or physical damage to the staff, the scattered glass fiber needs to be blown back into the processing area.
[0003] In the prior art, after the glass fibers scattered outside the processing area are purged and collected, some of the glass fibers are still adhered to the purging device and are not completely collected. In addition, in the prior art, after the scattered glass fibers are collected again, the collected glass fibers cannot be evenly laid out in the processing area, which affects the uniformity of the overall laying of the glass fibers and causes uneven strength of the sheet processing.
