Description
Technical field
The utility model relates to the sealing device of a kind of baking box transmission valve, especially relates to a kind of sealing device being suitable for the vacuum tunnel formula baking box transmission valve of lithium battery or lithium battery pole slice.
Background technology
At present, in new energy materials manufacturing process, also need if desired to toast new energy materials, to remove moisture content, such as, the manufacture of electrodes of lithium-ion batteries or lithium ion battery, just needs electrodes of lithium-ion batteries or lithium ion battery to carry out degree of depth oven dry.What modal drying plant adopted is Inner eycle list casing baking box, it first loads in vacuum bakeout case by the lithium battery be baked or battery electrode, again vacuum bakeout case is sealed, at ambient pressure, first the material that is baked in casing is heated, heat up, after the temperature inside the box reaches requirement, when being incubated, removing moisture will be vacuumized in casing, after the water content of battery pole piece reaches requirement, again the electrode of lithium cell be baked in casing or battery are cooled, nature can be selected to cool or force cooling, the temperature of electrode of lithium cell or the battery core be baked is dropped to a certain degree, the electrode of lithium cell be baked or battery are taken out sealing preserve, water content due to battery pole piece needs to reach very high requirement, and therefore, in whole process, the sealing of inner loop list casing baking box has strict requirement, crowd knows, in the manufacture process of electrodes of lithium-ion batteries or lithium ion battery, the operations such as the electrode slice coating before baking operation or the manufacture of battery are all the forms of continuous print streamline, and when will enter Inner eycle list casing baking box, thing to be dried is now just needed first to accumulate a certain amount of, put into described Inner eycle list casing baking box again to heat, heat up, the operation such as to vacuumize, although this kind of Inner eycle list casing baking box sealing is better, but this single casing baking box just makes baking operation cannot be streamline form with operations such as coatings before, and at every turn all need thing to be dried to insert in Inner eycle list casing baking box or in Inner eycle list casing baking box and take out, so just cause operation numerous and diverse, reduce production efficiency.
In order to solve the problem, enhance productivity, pertinent art investigated a kind of tunnel type vacuum oven, such as Chinese patent literature CN 102466394 A discloses a kind of apparatus and method for drying electrode plate, this kind of device is tunnel type vacuum oven, effectively can solve baking operation cannot be the problem of streamline form with operations such as coatings before, and sealing is fabulous; But this device is that external research and development manufacture, and domestic enterprise needs from external import, and price is extremely expensive, it is reported, the price of a hermatic door needs about hundreds of thousands, for domestic enterprise, particularly medium-sized and small enterprises, cannot afford to use; Although and the domestic manufacture had about tunnel type vacuum oven, is generally all that sealing is poor, does not solve sealing problem well.Therefore, for the problems referred to above, someone investigated encapsulating method and the device of a kind of vacuum tunnel formula baking box transmission valve again, its structure is, comprise and to be located between adjacent two working box and the protective cover that described working box is tightly connected, be located at reciprocal driving gate in described protective cover and for the first guide be arranged in parallel spaced a predetermined distance that moves reciprocatingly for described reciprocal driving gate and the second guide, described reciprocal driving gate comprises reciprocating drive mechanism, the hermatic door open-and-close mechanism be connected with described reciprocating drive mechanism, and the first hermatic door to be connected with described hermatic door open-and-close mechanism and the second hermatic door, the direction of the described reciprocal driving gate translation in described protective cover is provided with predetermined dodges space, when two described hermatic doors draw in, described reciprocal driving gate moves to described predetermined when dodging in space, the connection between described two described working box, on the contrary, then disconnect, ideally, when the pressure of adjacent two described working box is equal, the gathering of two hermatic doors or to push open be all easily realize, but in reality, the pressure of adjacent two described working box can not be completely equal, always there is certain difference between them, and there is difference and just mean that two described hermatic doors can have difficulties when carrying out drawing in or pushing open, such as when drawing in, the hermatic door of the working box side that pressure is little is then difficult to draw in, if now proceed reciprocal driving gate to move to the predetermined action of dodging space, then be easy to the sealing ring rubbed with the hands between bad hermatic door and working box, serious even can damage hermatic door and working box, greatly reduces the service life of sealing ring, hermatic door and working box, and the elimination of pressure difference in the scope that process conditions allow, be also need the regular hour, and compare and be difficult to carry out, so not only need consumes resources, and can production efficiency be affected.
