Improved transfer valve

Abstract

An improved transmission valve comprises a transmission valve element, wherein the transmission valve element comprises a first sealing door, a second sealing door and a lifting mechanism, a first lifting plate is arranged between the first sealing door and the second sealing door, and the first sealing door and the second sealing door are connected with the first lifting plate through a first hinging part and a second hinging part respectively; a second lifting plate is arranged above the first lifting plate, and the second lifting plate is connected with the first lifting plate through a third hinging part; the lifting mechanism comprises a driving mechanism, a lead screw and a nut, the nut is fixed to the second lifting plate, and the driving mechanism is connected with the nut through the lead screw. The valve has the advantages that debugging time can be shortened, and asynchronous sealing of sealing door planes is avoided.

Description

technical field [0001] The invention relates to a transfer valve, especially an improved transfer valve suitable for a vacuum tunnel oven. Background technique [0002] In the production process of lithium batteries, it is necessary to vacuum dry them to reduce the moisture contained in lithium batteries so that they can meet the corresponding use requirements. The traditional vacuum drying is carried out in a separate vacuum oven. The rolled battery pole pieces are placed in a separate vacuum oven, and then the vacuum oven is heated, vacuumed and cooled to a certain temperature. Finally, the battery pole piece is taken out; because the traditional vacuum oven has low baking efficiency and other problems, in order to improve efficiency, someone has developed a tunnel-type vacuum oven, and the adjacent box of the tunnel-type vacuum oven The sealing problem between them is very important, it affects the drying effect and efficiency of the battery pole piece, therefore, in ord...

Problems solved by technology

The traditional vacuum drying is carried out in a separate vacuum oven. The rolled battery pole pieces are placed in a separate vacuum oven, and then the vacuum oven is heated, vacuumed and cooled to a certain temperature. Finally, the battery pole piece is taken out; because the traditional vacuum oven has low baking efficiency and other problems, in order to improve efficiency, someone has developed a tunnel-type vacuum oven, and the adjacent box of the tunnel-type vacuum oven The sealing problem between them is very important, it affects the drying effect and efficiency of the battery pole piece, therefore, in order to improve the sealing between the adjacent boxes of the tunnel vacuum oven, people also pay attention to the sealing of the tunnel vacuum oven. For further research and improvement, for example, Chinese patent document CN 204163565 U discloses a self-sealed door, which includes a first door panel and a second door panel arranged in parallel, and a The lifting mechanism for lifting the first door panel and the second door panel is provided with at least two hinges between the first door panel and the lifting mechanism, one end of the hinge is hinged with the first door panel, and the other is hinged. One end is hinged with the lifting mechanism, and at least two hinges are arranged between the second door panel and the lifting mechanism, one end of the hinge is hinged with the second door panel, and the other end is hinged with the lifting mechanism. The mechanism is hinged, a first roller is provided at the lower end of the first door panel, a first slope with a low left and a high right is provided under the first roller, and a second roller is provided at the lower end of the second door panel, A second slope with a high left and a low right is provided below the second roller

[0003] The above-mentioned automatic sealing door has the following problems during use. First, when the first door panel and the second door panel are sealed, due to the influence of manufacturing accuracy or installation accuracy, the first door panel and the second door panel will be out of sync as a whole. Sealing, that is, the first door panel is sealed well, but the second door panel is not yet sealed. In this way, it takes a long time to debug to meet the usable requirements. Even if the first door panel and the second door panel are used for the first time The door panels have been adjusted to meet the synchronization requirements, but after a period of use, there will be out-of-synchronization problems, and the sealing effect will not be good; the second is that the plane of the first door panel or the second door panel itself is not sealed synchronously, that is, the second door panel will appear. The lower part of the first door panel or the second door panel is attached to the oven, but the upper part has not been fully attached; the third is that the existing lifting device adopts a rack and pinion structure, and the rack will be deformed due to too long, resulting in lifting difficult question
