Connecting device for seal heating strip of vacuum sealing machine

Abstract

The invention provides a connecting device for a seal heating strip of a vacuum sealing machine. The connecting device for the seal heating strip of the vacuum sealing machine comprises a heating strip base and the heating strip, a connecting device is arranged on the upper portion of the heating strip, the connecting device is connected with an air cylinder, the connecting device comprises a spherical column head and a spherical seat, the spherical column head is arranged on a telescopic rod of the air cylinder, the spherical seat is arranged on the heating strip and provided with a spherical groove, and the spherical column head is meshed with the spherical groove. Infirmness of sealing of an aluminum film seal due to too low local temperature is reduced, local melting of an aluminum film of the aluminum film seal due to too high temperature is reduced, and the phenomenon that the aluminum film seal has melted white spots of different sizes is reduced.

Description

technical field [0001] The technology of the present invention relates to the packaging technology of a vacuum packaging machine, more specifically, an improvement of the connection between the entire device of the sealing heating strip of the vacuum packaging machine and the base of the heating strip. Background technique [0002] The levelness of the whole device of the upper and lower heating strips of the vacuum packaging machine directly determines the temperature uniformity of the heating strips of the vacuum packaging machine, and determines the packaging quality of the aluminum film and its composite materials. If the level difference of the upper and lower heating strips is large, the packaging quality will be affected. It clearly shows the coexistence of weak local packaging and local scalding (white spots). If this poor packaging quality problem occurs, it is useless to adjust the heating temperature, heating ratio, heating time, etc. of the heating process. The f...

[0002] The levelness of the whole device of the upper and lower heating strips of the vacuum packaging machine directly determines the temperature uniformity of the heating strips of the vacuum packaging machine, and determines the packaging quality of the aluminum film and its composite materials. If the level difference of the upper and lower heating strips is large, the packaging quality will be affected. It clearly shows the coexistence of weak local packaging and local scalding (white spots). If this poor packaging quality problem occurs, it is useless to adjust the heating temperature, heating ratio, heating time, etc. of the heating process. The fixing is firm, and the levelness meets the assembly quality requirements. The original bolt connection is mainly because the heating strips are combined together during work. The impact of the upper and lower heating strips will easily loosen the fixing bolts, and the levelness of the heating strips will be damaged and changed. It is difficult for maintenance personnel to debug large, poor stability
