An automatic capping device for radioactive sample bottles

Abstract

The invention relates to an automatic cap screwing device of a radioactive sample bottle. The automatic cap screwing device comprises a power source, a coupling, a cap opening head, a clamping part and a lifting part, wherein the power source drives the cap opening head to rotate through the coupling, the clamping part and the lifting part act on a to-be-opened container so as to be matched with the cap opening head to rotate to enable a cap of the to-be-opened container to be separated from a container body, the cap opening head comprises a framework and an elastic friction part which is at least partially wrapped outside the framework, and the elastic friction part can clamp the cap after being extruded and deformed by the cap. The automatic cap screwing device has the advantages that the elastic friction part (polyurethane is taken as an example) is wrapped on the outer surface of the built-in framework of the cap opening head for cap screwing, so that great elasticity and frictionare achieved, when the cap is screwed, the bottle cap can be effectively clamped, the cap cannot fall off after the bottle cap and the bottle body are separated, the bottle cap clamping device is greatly simplified through the design, and the maintenance mode is simplified.

Description

technical field [0001] The invention belongs to the field of nuclear industry, in particular to an automatic capping device for radioactive sample bottles. Background technique [0002] At present, there are a wide range of capping machines on the market, which are used in various industries. But in the field of nuclear industry, involving nuclear reaction materials, there is a lot of radiation pollution. For the opening and closing operation of radioactive sample vials, one needs to consider the problem of leakage to ensure that personnel can stay in a safe area away from the operation site, and the other is that after the general capping machine caps, the cap may fall off from the capping head. This is a very serious matter in a radiation environment. In the prior art, to solve the technical problem that the lid is easy to fall off after opening, the manipulator is generally used to replace the cap opening head for the cap opening operation. The disadvantage is that the ...

Problems solved by technology

In the prior art, to solve the technical problem that the cover is easy to fall off after opening, the manipulator is generally used to replace the cap opening head for the cap opening operation. The disadvantage is that the operation of the manipulator is relatively complicated, the price is high, and once a failure occurs, maintenance is quite troublesome.
