A packaging bag sealing device

Abstract

The invention discloses a packaging bag sealing device comprising a conveying belt, an extrusion wheel, a tamping wheel, pressure bearing rollers, an outer ring, an inner ring and an induction heating coil; each of the left and right ends of the inner side of the conveying belt is provided with a driving roller; the conveying belt is of a conveying structure located between the driving rollers; the driving rollers are driven by and connected with a first driving motor; each of the front and rear sides of each driving roller is provided with a driving belt protecting shell; the lower end of each driving belt protecting shell is provided with supporting legs which are regularly distributed; the lower ends of all the supporting legs are fixedly arranged at the upper ends of bottom plates; the upper end of each driving belt protecting shell is provided with upright columns which are regularly distributed; the pressure bearing rollers are mounted at the upper ends of the upright columns through rotating shafts and are abutted with the inner wall at the upper end of the conveying belt; and the extrusion wheel is arranged at the left side of the middle part right above the conveying belt. The packaging bag sealing device is simple in structure, the embarrassment that a product is stained with a packaging bag melting liquid is avoided, and the sealing performance of a packaging bag is enhanced.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a packaging bag sealing device. Background technique [0002] Packaging (packaging) is the general name of containers, materials and auxiliary materials used according to certain technical methods to protect products during circulation, facilitate storage and transportation, and promote sales. Whether it is in the field of food processing, small parts processing, or daily necessities processing. All need to pack the product into a plastic packaging bag, and then need to use a sealing device to seal the plastic packaging bag. At present, the device used in the industry to seal plastic packaging bags is a simple heating device. When in use, the staff first holds the packaging bag, passes the position to be sealed through the heating device, so that the sealing position is heated and melted; then, the staff tightens the position where the food plastic pack...
