Sampling device

Abstract

The invention discloses a sampling device. The sampling device comprises an inner driving cylinder, a connector and an inner disc, wherein the connector is fixedly arranged at the right end of the inner driving cylinder and is in transmission connection with a power mechanism; the inner disc is fixedly arranged at the left end of the inner transmission cylinder; inner cutting teeth are arranged on the outer side of the outer periphery of the inner disc; a sleeve is arranged at the left end of the inner driving cylinder in a front and back sliding manner; an outer disc is arranged on the end part of the sleeve; outer positioning teeth are arranged on the outer side of the outer periphery of the outer disc and are positioned on the outer side of the inner cutting teeth; the facing directions of the tooth tips of the outer positioning teeth are opposite to the facing directions of the tooth tips of inner poisoning teeth. According to the sampling device, by adopting the design of the inner disc and the outer disc and utilizing a firm-grasp function of the outer positioning teeth, the outer positioning teeth firmly grasp under a counter-acting force function when the inner cutting teeth work, so that the successful operation of a whole sampling process can be effectively guaranteed; meanwhile, by adopting the positioning of the outer positioning teeth on the outer part of the sampling device, the damage to the interior of the sampling plate is avoided, and the completeness of the sample can be effectively guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a sampler. Background technique [0002] When preparing plastic products, such as plastic light distribution mirrors, sampling tests are required, that is, cutting 80mm-100mm samples on a formed plastic light distribution mirror. The general method is to use a jigsaw or a hole reamer. Take out the sample on a flat surface, and the sample taken out by a hole reamer has a hole in the middle, but for a special-shaped surface or a curved plastic product, when a sheet-like sample is removed and wear is not allowed, the curve saw cannot be used to cut the curved surface. However, the use of a hole reamer may result in a hole in the center that does not meet the sampling requirements. At present, it can only be cut out manually with a knife, which will damage the surrounding area. Usually, only one sample can be taken out of a finished product, which is a serious waste. At the same ...

[0002] When preparing plastic products, such as plastic light distribution mirrors, sampling tests are required, that is, cutting 80mm-100mm samples on a formed plastic light distribution mirror. The general method is to use a jigsaw or a hole reamer.

However, the use of a hole reamer may result in a hole in the center that does not meet the sampling requirements. At present, it can only be cut out manually with a knife, which will damage the surrounding area. Usually, only one sample can be taken out of a finished product, which is a serious waste. At the same time, because the product is hard. , the cutting efficiency of the tool is low
