Development Of Mechanical Screwing With Sealed Medical Waste Collection Device

Medical waste contains a large number of germs:bacteria, viruses, fungi, and can generate a variety of harmful chemical substances, these harmful substances can contact or with the wind and airflow role of the media, and spread to the surrounding environment, serious harm to human health. Exposure to medical waste stored in closed containers in a timely manner, can effectively prevent the bacteria spread to the surrounding environment, with the role of the media such as wind and airflow to avoid harmful objects cause secondary pollution on the surrounding environment. Therefore, the medical institutions at all levels in urgent need of a kind of waste collection device, which contain collector and sealed. Demand for medical institutions, the development of a mechanical screwing sealing medical waste collection device, the apparatus can not only achieve the collection of medical waste, but also for sealing medical plastic bag containing medical waste. The work carried out in this article:(1)Designed a machine that can automatically complete sealing equipped with medical waste plastic medical waste collection device. Using SolidWorks software prototype three-dimensional modeling to generate a3D assembly model and assembly drawings. The device mainly includes walking the caster, transmission, sealing institutions, multi-finger grab mechanism, rotation within the barrel. Sheaves, gear consisting of a combination of transmission mechanism transmission mechanism, the agency uses a motor-driven reversing rotary motion of the inner barrel, multi-fingered hand grasp and release objects as well as sealing the reciprocating linear motion. Transmission mechanism design:the calculation of the transmission ratio of the gear mechanism design, dynamic stop geneva mechanism than the sheave wheel groove tree design, the design of the shaft and checking, and the selection of the bearing, the motor power.(2)The tape stripping of the mechanical model, by introducing the theory of fracture mechanics fracture and fracture energy release, the establishment of the dynamic equations of the adhesive tape is peeled off from the matrix; obtained by tape stripping speed and peel force relations, has been to achieve tapeminimum actuating force needed to peel.(3) Sealing organizations sealed plastic bag mouth five working process, analysis of the tape sealing mechanism on flexible plastic bags, wound sealing process; the spring bearing position of the sealing mechanism has been optimized, so that the binding mechanism in the minimum driving force conditions, bunched plastic bags tied.(4) Multi-finger grab a qualitative analysis of the different types of crawl crawl matrix, multi-finger grab mechanism using ADAMS software simulation, multi-finger finger-side contact with the object of clamping force, and morefinger to grab an object process speed curve.
