High polymer material sample preparation system and sample preparation method

Abstract

The invention belongs to the technical field of high polymer material testing, and discloses a high polymer material sample preparation system and a sample preparation method. The system comprises a base, the base comprises a top plate and supporting legs arranged below the top plate, in the length direction of the top plate, one end of the top plate is the head end, the other end of the top plate is the tail end, a pair of driving rollers is arranged at the two ends of the top plate, an annular conveying belt matched with the driving rollers is further arranged on the top plate, and a clamping device is arranged on the conveying belt; a thinning device, a flaw detection device, a blanking device, a material picking device and a waste recovery device are sequentially arranged on the top plate from the head end to the tail end of the top plate. The system further comprises a control module for controlling linkage of the material clamping device, the thinning device, the flaw detection device, the blanking device, the material picking device and the waste recovery device. The problems that in the prior art, the automation degree is low during sample strip preparation, internal defects of sample strips are difficult to detect, cut-off knife storage is not changed, and manpower and resource waste is serious are solved.

Description

technical field [0001] The invention relates to the technical field of polymer material testing, in particular to a polymer material sample preparation system and a sample preparation method. Background technique [0002] In the process of research and development of polymer materials and product production, it is necessary to continuously test material performance indicators or product quality, so it is necessary to quickly prepare samples of various sizes and specifications, perform performance test analysis quickly, and adjust formulas and processes in time. [0003] In the production process of rubber products, samples need to be taken from the product. The current sampling method is to manually use a knife or cutting machine to remove an irregularly shaped rubber block or rubber plate from the product. The thickness of the rubber block or plate varies from place to place. Even, it is impossible to directly prepare samples for performance testing, and it needs to be cut ...

Problems solved by technology

[0003] In the production process of rubber products, samples need to be taken from the product. The current sampling method is to manually use a knife or cutting machine to remove an irregularly shaped rubber block or rubber plate from the product. The thickness of the rubber block or plate varies from place to place. Even, it is impossible to directly prepare samples for performance testing, and it needs to be cut several times to reach the specified thickness, especially when the removed rubber block or rubber sheet has irregular shape and large thickness, it needs long cutting time, high labor intensity and low efficiency

[0004] After cutting to the specified thickness of the test piece, the qualified test piece is usually screened out with the naked eye, and the test piece or part with surface defects should be avoided as much as possible when punching the spline with a knife, and then cut into samples of different specifications with a knife of different specifications. Different performance indicators can be obtained through testing; the current spline punching process is manual punching, and multiple sets of knives are used for punching. If there are holes or large particles in the test piece, the naked eye cannot observe it in advance. It is realized that the test results can only be fed back in the later stage, which will lead to invalid test results and need to be re-tested, resulting in a waste of manpower, time and resources; moreover, splines of different specifications need to use a variety of different cutting knives , It is troublesome to classify and store the cutting knives, and it is inconvenient to manage
