Description
Technical field
The present invention relates to a kind of transmission valve, especially a kind of improved transmission valve suitable for vacuum tunnel formula baking box.
Background technology
In Production Process of Lithium Battery, need to be vacuum dried which, reduce contained in lithium battery by being vacuum dried
Moisture so which meets corresponding use requirement.Traditional vacuum drying is carried out in single vacuum bakeout case,
The battery pole piece of rolling is placed in single vacuum bakeout case, then vacuum bakeout case is heated up, evacuation and cooling,
After being cooled to uniform temperature, battery pole piece is taken out；Because there is baking in traditional vacuum bakeout case, because
This, in order to improve efficiency, someone investigated tunnel type vacuum bakeout case, and between the adjacent boxes of tunnel type vacuum oven
Sealing problem is particularly important, and it affects the effect and efficiency of battery pole piece drying, therefore, bake to improve tunnel type vacuum
Sealing between the adjacent boxes of case, people are made further research and are improved, example to the sealing of tunnel type vacuum oven again
Such as, 204163565 U of Chinese patent literature CN discloses a kind of automatic seal door, including the first door-plate be arrangeding in parallel and
Second door-plate, is provided with lifting first door-plate, the liter of the second door-plate between first door-plate and second door-plate
Descending mechanism, at least provided with two articulated elements, one end of the articulated elements between first door-plate and the elevating mechanism
It is hinged with first door-plate, the other end is hinged with the elevating mechanism, between second door-plate and the elevating mechanism
Also at least provided with two articulated elements, one end of the articulated elements is hinged with second door-plate, the other end and the elevator
Structure is hinged, and the lower end of first door-plate is provided with the first roller, and left low right height is provided with below first roller
The first inclined-plane, the lower end of second door-plate is provided with the second roller, left height is provided with below second roller
Right the second low inclined-plane.
, there is following Railway Project in above-mentioned automatic seal door, one is the first door-plate and the second door-plate in use
In sealing, due to the impact of the accuracy of manufacture or installation accuracy, the integrally asynchronous sealing of the first door-plate and the second door-plate can be caused,
The first door-plate good seal, but the second door-plate not yet good seal occurs, so, it is necessary to which prolonged debugging just can be with
The requirement that can be used is reached, though in first use, the first door-plate and the debugging of the second door-plate are arrived into the requirement of synchronization, but
Be, using a period of time after, nonsynchronous problem occurs again, can also cause sealing effectiveness bad；Two is the first door-plate or
The asynchronous sealing of plane of two door-plates itself, that is, occurred and fitted with case baking box below the first door-plate or the second door-plate, but
The problem that top is not also fitted completely；Three is that existing lowering or hoisting gear uses gear ＆ rack structure, due to tooth bar it is long
Can deform, and produce the difficult problem of lifting.
The content of the invention
The purpose of the present invention is, for the problems referred to above, to provide one kind to society and can shorten debug time, and will not go out close
