The invention relates to a sealing system for closing a vacuum bag and a sealing method for closing a vacuum bag. The sealing system comprises: a guide (1) that guides a pair of layers (2); and a sealing roller (3) which applies heat and pressure to the edges of the layers (2) for sealing the layers (2) against each other, said sealing roller (3) being movable along said edges. The sealing method comprises: aligning a pair of layers (2) such that a portion of one of the layers (2) is placed in front of a portion of the other layer (2), thereby defining an edge; applying heat and pressure to said edge of the layer (2) by means of a heating roller (3); and moving the heating roller (3) along the edges of the layers (2), sealing the two layers (2) against each other at the edges, thereby forming a vacuum bag. The method allows the problem of labor-intensive sealing methods to be solved by introducing an automatic sealing system that uses a zipper-like manner for vacuum bag closure.

The invention discloses a sealing cover and a using method thereof.The sealing cover comprises an outer-layer cover body and an inner-layer cover body, the outer-layer cover body is provided with an anti-loosening structure, and the anti-loosening structure is provided with a mounting position; the inner-layer cover body is arranged on the inner side of the outer-layer cover body, and the inner-layer cover body can be screwed and matched with the bottle body, so that at least one part of the convex blocking part of the bottle body is arranged in the mounting position; wherein the inner-layer cover body is provided with an anti-opening structure, the anti-opening structure is arranged behind the anti-loosening structure in the screwing direction of the inner-layer cover body and the bottle body, and the anti-opening structure is used for providing appearance indication for opening of the sealing cover. The anti-loosening function and the anti-opening function can be prevented from failing at the same time when a product is impacted, and the problem that the opening experience of a user is affected due to the fact that the unscrewing torque is too large is solved.

The application provides a sealing structure, a compressor and a control method. The sealing structure comprises: a rotating shaft, wherein an impeller component is arranged on the rotating shaft; a shaft sleeve, wherein the shaft sleeve is sleeved on the rotating shaft, and the rotating shaft is rotatably arranged relative to the shaft sleeve; a sealing seat, wherein the sealing seat is sleeved on the shaft sleeve, a flow passage is arranged on the sealing seat, a cooling passage is arranged between the sealing seat and the impeller component, the cooling passage is communicated with the flow passage, and the cooling passage is communicated to the outside of the impeller component; and a sealing component, wherein the sealing component is in abutment with the sealing seat, and the sealing component and the shaft sleeve have a sealing passage communicated with the flow passage; and the sealing component expands when encountering water. The sealing structure solves the technical problems of difficult sealing of the compressor and short service life of the sealing in the related art.

The present application belongs to the technical field of kiln loading and unloading, and particularly relates to a sealed kiln automatic loading and unloading system and method. The sealed kiln automatic loading and unloading system comprises a sealed chamber, a cleaning mechanism, a feeding mechanism and a punching mechanism. The unloading robot, the punching mechanism and the feeding robot are all in the sealed chamber. The sealed chamber is filled with inert gas.
