Description

Technical Field

[0001] The utility model relates to the technical field of filter membrane processing, in particular to a filter membrane processing and cutting device. Background Art

[0002] Microporous filter membranes include mixed fiber microporous filter membranes, polypropylene filter membranes, polyethersulfone filter membranes, polyvinylidene fluoride filter membranes, polytetrafluoroethylene filters, and nylon filter membranes. They are mainly used for sample analysis, especially for filtering mobile phases and samples in chromatographic analysis. A cutting device is required to cut the filter membrane during filter membrane processing.

[0003] For example, authorization announcement number CN218462320U discloses a cutting device for processing water filtration membranes, comprising a bottom plate, a vertical plate fixedly connected to the front side and the rear side of the top of the bottom plate, a second top plate and a first placement plate fixedly connected to the top and bottom of the inner middle end of the vertical plate, a first cylinder fixedly mounted on both sides of the top of the second top plate, a fixed plate fixedly mounted on the bottom of the first cylinder, a rubber plate fixedly mounted on the middle end of the bottom of the fixed plate, and the first top plate and the second placement plate fixedly mounted on the top and bottom of the inner middle end of the vertical plate. The utility model achieves the effect of clamping and fixing the filtration membrane by fixing the second top plate and the first placement plate on the top and bottom of the inner middle end of the vertical plate, fixing the first cylinder fixedly mounted on both sides of the top of the second top plate, fixing the fixed plate fixedly mounted on the bottom of the first cylinder, and fixing the rubber plate fixedly mounted on the middle end of the bottom of the fixed plate, thereby facilitating cutting by the cutting device and improving cutting efficiency.

[0004] Based on the search of patent numbers and combined with the deficiencies in the prior art, we found that:

[0005] Although this cutting device for processing water filter membranes can clamp and fix the filter membrane and is convenient for the cutting device to cut it, during use, since the fixing plate drives the rubber plate to descend, it can only clamp and fix the middle section of the filter membrane. When the cutting knife cuts the filter membrane on the top of the second placement plate, the cut end of the filter membrane loses the tension. At this time, the filter membrane between the first placement plate and the second placement plate falls due to its own gravity. Therefore, the user needs to reposition the fallen filter membrane on the top of the second placement plate before subsequent cutting. Therefore, it is more troublesome to use and will lead to a decrease in work efficiency. Utility Model Content
