Description

Lithium electricity feeding spiral seal structure Technical Field The utility model mainly relates to the technical field of lithium battery feeding, in particular to a spiral sealing structure for lithium battery feeding. Background In the process of the vigorous development of the lithium battery industry, a lithium battery feeding link is used as a basic process of production, when the lithium battery is fed, a spiral is generally adopted to convey raw materials, the performance of a spiral sealing structure of the spiral feeding link has a decisive effect on the quality of products and the production safety, and in the lithium battery production process, the spiral sealing structure can prevent materials from leaking and isolate the interference of external air, and maintain the stable working environment in equipment so as to ensure that the performance of the lithium battery materials is not influenced and ensure the continuity of the production flow. However, the sealing structure of the traditional lithium battery feeding spiral sealing structure is single, a single sealing piece is used for sealing, a single sealing mode is difficult to cope with complex working conditions, the overall sealing reliability is poor, the problem of sealing failure frequently occurs, the equipment maintenance cost is increased, potential safety hazards are possibly caused by sealing failure, and the improvement of the lithium battery production efficiency and quality is restricted. Disclosure of utility model The technical scheme of the utility model aims at the technical problem that the prior art is too single, provides a solution which is obviously different from the prior art, and mainly provides a lithium battery feeding spiral sealing structure which is used for solving the technical problem that the sealing structure of the traditional lithium battery feeding spiral sealing structure is relatively single. The technical scheme adopted for solving the technical problems is as follows: The utility model provides a lithium electricity feeding spiral seal structure, includes the casing, the outside of casing is equipped with air inlet and gas vent respectively, the inside lip seal circle, labyrinth seal and the bearing of being provided with of casing, one side of casing is provided with the installation tube, the inner wall of installation tube is provided with the organic glass mirror. Further preferably, a pressure sensor and an electromagnetic exhaust valve are arranged on the inner wall of the exhaust port, and the pressure sensor is used for monitoring cavity pressure. Further preferably, a locking round nut is arranged on one side of the bearing for locking the axial position of the bearing component. Further preferably, a limiting ring is arranged on the inner wall of the mounting tube, an annular sealing groove is arranged on one side, close to the organic glass mirror, of the limiting ring, and an elastic sealing ring is adaptively arranged in the groove. Further preferably, an insert ring is convexly arranged on one side of the shell, and an annular groove matched with the insert ring is formed on one side of the installation tube corresponding to the insert ring. Further preferably, a plurality of screw holes distributed in an annular array are formed in one side of the mounting tube and two sides of the shell, and the mounting tube and the shell are detachably connected through bolts. Compared with the prior art, the utility model has the beneficial effects that: The lithium battery feeding spiral sealing structure is characterized in that sealing gas is introduced through an air inlet to establish a micro-positive pressure environment, a lip-shaped sealing ring and a labyrinth seal are matched to form a multi-stage sealing structure, the micro-positive pressure environment prevents material leakage and prevents external air from invading, the lip-shaped sealing ring is tightly attached to a spiral shaft and can be elastically compensated after abrasion, the labyrinth seal reduces leakage through throttling effect, the three cooperate with each other to greatly improve overall sealing reliability, the stability of the internal working environment of equipment is effectively ensured, meanwhile, an organic glass mirror is used as an observation window, an operator can intuitively check the working condition of sealing components in a sealing cavity without disassembling the equipment, and the problems of material leakage, abnormal sealing elements and the like are timely found.
