Pricking pin coaxiality sorting device

Abstract

The invention discloses a pricking pin coaxiality sorting device which is characterized in that a guide rail with a slide block is arranged on a table top, one end of the guide rail is suspended outside the table top, a sorting device is arranged right below the suspended end of the guide rail, and a first electric magnet is arranged right above the suspended end of the guide rail; a flat board with a tank is arranged on the slide block, one end of the flat board with the tank, opposite to the direction of the suspended end of the guide rail, is provided with a connecting block connected withan eccentric wheel on a rotating shaft of a first stepping motor arranged on the table top through a connecting rod, the connecting rod can freely move in the direction of the axis of the guide rail relative to the connecting block and the eccentric wheel, a friction board is arranged right above the guide rail near to the suspended end of the guide rail, and a detecting device is arranged on thetable top at one side of the guide rail and opposite to the friction board; and the first stepping motor, a second stepping motor in the detecting device, a contact block, the first electric magnet and a second electric magnet in the sorting device are electrically connected with a single-chip machine. The pricking pin coaxiality sorting device conveniently and high-efficiently realizes the automatic sorting of excellent and bad pricking pin coaxialities.

Description

technical field [0001] The invention relates to a coaxiality sorting device, in particular to a needle coaxiality sorting device Background technique [0002] Needle is one of the important tools in non-woven fabric processing, which has an extremely important impact on the processing quality of non-woven fabrics. The quality of the coaxiality of the needle directly affects the service life of the needle product, and is an important indicator reflecting the quality of the needle product, and has become a must-check item before the needle product leaves the factory. At present, artificial sensory detection is generally used, that is, the degree of curvature is inspected by naked eyes under light irradiation. This method is not only inefficient, but also easily causes high false detection rate or missed detection rate due to eye fatigue. The axiality detector can also detect the coaxiality of the puncture needle, but due to the low detection efficiency, it can only be used fo...

Problems solved by technology

At present, artificial sensory detection is generally used, that is, the degree of curvature is inspected by naked eyes under light irradiation. This method is not only inefficient, but also easily causes high false detection rate or missed detection rate due to eye fatigue. The axiality detector can also detect the coaxiality of the needle, but due to the low detection efficiency, it can only be used for sampling inspection, and it is not suitable for the full inspection of products.

At present, there is no automatic detection equipment for coaxiality of needles in the market, and it is urgent to invent a device that can quickly and accurately judge whether the coaxiality of needles is qualified or not, and can also sort out unqualified needles.
