Description

Technical Field

[0001] The utility model relates to the technical field of paper sampling equipment, in particular to a paper internal bonding strength testing sampling platform. Background Art

[0002] The internal bonding strength of paper refers to the tightness of the fiber structure inside the paper, also known as cohesion. It refers to the degree of bonding between fibers inside the paper, that is, the mutual adsorption between fibers. The higher the internal bonding strength of the paper, the tighter the bonding between the fibers, and the better the strength, hardness, durability and tensile strength of the paper.

[0003] The existing paper internal bond strength test requires an internal bond strength tester to test the paper sample. Before that, paper sampling is required. The existing paper sampling method mainly fixes the paper on the sampling table by means of adhesive tape, and then clamps the paper by means of a clamp. Finally, the paper is cut into multiple samples for testing on the internal bond strength tester by manual cutting with a utility knife or other cutting tools. Although paper sampling can be achieved, due to the influence of the characteristics of the adhesive tape, the method of cutting in batches will cause the cutting characteristics of each paper sample to be different. The human factor has a greater impact, and the results of multiple cuttings by different operators are different. Even the results of each cutting by the same operator are different, resulting in deviations in the subsequent test results of the paper samples. Summary of the invention

[0004] The utility model aims to provide a paper inner bonding strength test sampling platform, which can improve the cutting consistency and cutting quality of paper samples, thereby improving the accuracy of paper sample detection.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a paper internal bonding strength test sampling station, and the specific implementation scheme is as follows:

[0011] The cutting mechanism is arranged below the sampling fixture, and cutting blades are arranged at positions on the cutting mechanism corresponding to the gaps, and all the cutting blades enter the cutting gaps synchronously.

[0012] Compared with the prior art, the utility model discloses a paper internal bonding strength test sampling table. A cutting gap is provided between every two adjacent sampling clamps. A cutting blade is arranged at a position corresponding to the gap of the cutting mechanism. In actual use, a fixing glue is first bonded to the sampling clamp, and then the paper sample to be sampled is laid on the fixing glue. Then, a sampling pressing block with the fixing glue is placed on the paper sample. The fixing glue cooperates with the clamping effect of the sampling pressing block and the sampling clamp to fix the paper sample and the sampling clamp. Then, all the cutting blades are simultaneously entered into their corresponding cutting gaps to obtain a plurality of paper samples with consistent cutting directions, cutting forces and cutting results. The cutting consistency and cutting quality of the paper samples can be improved, thereby improving the accuracy of paper sample detection.

[0013] In some embodiments, the cutting mechanism comprises:
