Description

Technical Field

[0001] The utility model belongs to the technical field of sealing devices, and in particular relates to a sealing device for a feeding rotating shaft of a bag feeding packaging machine. Background Art

[0002] In sauce processing factories, bag packaging machines are often used. The bag packaging machine conveys the sauce in the plate through a feeding disc, and finally sends the sauce into the packaging bag and seals it. When the bag packaging machine is in use, there is a gap at the connection between the rotating shaft and the feeding disc. The sauce can easily flow from the gap to the bottom of the feeding disc and eventually drip into the inside of the equipment. The sauce falling into the equipment causes oil and dirt mixing, which will damage the main drive and leave residues that cannot be removed in the gap. The resulting spoiled odor affects food safety, so it is necessary to provide a sealing device to seal the connection between the rotating shaft and the feeding disc. Utility Model Content
