Description

Technical Field

[0001] The utility model relates to the technical field of film sampling, in particular to a manual sampler. Background Art

[0002] Most plastic films need to undergo tensile testing during the production process to check whether the tensile properties of the film meet the production specifications. Currently, manufacturers usually cut a section of film samples during the production process and then test the samples so that they can notify the production line in time to make adjustments if problems are found. Existing samplers usually use a mold plate to press the film down, and then cut the film along the edge of the mold plate. This operation is relatively cumbersome and cannot be implemented under conditions of rapid production, and the efficiency is low. Utility Model Content
