Sealing Device for Automatic Bagging Machine

Abstract

A sealing device for an automatic bagging machine contains: a film sealing assembly including a first seal, a second seal mount opposite to the first seal mount; a slide assembly including an elongated plate, a rail arranged on the elongated plate, and a sliding piece fixed on the rail; a cutting module including a cylinder seat, a mounting sheet, four screwing elements, a driving cylinder, and a roller. The cylinder seat is mounted on one side surface of the sliding piece, and the driving cylinder and the roller are inserted through the second seal mount. Between the cylinder seat and the mounting sheet are defined a central shaft and two gaps on two sides of the central shaft. In addition, at least two springs are arranged between the cylinder seat and the mounting sheet and are fitted on the four screwing elements.

What is claimed is: 
     
         1 . A sealing device for an automatic bagging machine comprising:
 a film sealing assembly including a first seal mount disposed on a left side thereof and being a hollowly elongated frame, a second seal mount mounted on a right side thereof opposite to the first seal mount and being a hollowly elongated frame;   a slide assembly including an elongated plate, a rail arranged on one side of the elongated plate, and a sliding piece fixed on the rail;   a cutting module including a cylinder seat, a mounting sheet connected with the cylinder seat, four screwing elements screwed with the cylinder seat through four corners of a first side of the mounting sheet, a driving cylinder secured on a second side of the mounting sheet, and a roller disposed on the driving cylinder; the cylinder seat being mounted on one side surface of the sliding piece, and the driving cylinder and the roller being inserted through the second seal mount; characterized in that:   between the cylinder seat and the mounting sheet are defined a central shaft and two gaps on two sides of the central shaft.   
     
     
         2 . The sealing device for the automatic bagging machine as claimed in  claim 1 , wherein at least two springs are arranged between the cylinder seat and the mounting sheet and are fitted on the screwing elements.
