Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery, and particularly relates to a longitudinal sealing device for an intermittent packaging machine. Background Art
[0002] In the field of medium measurement soft packaging bag production, films such as plastic films, paper films, and aluminum films are used to package filled materials. For the packaging of liquids and viscous substances by such packaging equipment, a sealing plate structure is generally used for intermittent packaging. Its longitudinal sealing structure is provided with left and right sealing plates, and heating rods are installed inside the left and right sealing plates. This often requires: for the longitudinal sealing of the packaging bag, its width can be adjusted at any time during the machine packaging process; due to the obstruction of the longitudinal sealing plate assembly, it needs to be opened to facilitate the initial film threading and maintenance adjustment of the machine; during the machine packaging process, the left and right sealing plates in the longitudinal sealing plate assembly are closed, and the heating rods control the heating of the sealing plates to achieve the heating and a certain degree of pressing of the packaging film. However, during shutdown maintenance, etc., the left and right sealing plates need to be opened to avoid over-roasting of the packaging film; since the left and right sealing plates are plate-like structures, the pressure on the packaging film cannot be too large, otherwise it will hinder the longitudinal movement of the film. Therefore, the sealing strength of the film is insufficient. At the same time, the longitudinal sealing of the packaging film also requires longitudinal embossing. For this purpose, special left and right roller groups need to be added, including left and right rubber sealing rollers and left and right multi-ringed rollers. The longitudinal sealing of the packaging bag is re-sealed by the rubber sealing rollers to improve the longitudinal sealing strength of the packaging bag without hindering the movement of the film. Through the left and right ringed rollers, isolation patterns are pressed along the longitudinal sealing direction of the packaging bag to enhance the front strength of the seal and increase the appearance beauty of the sealing area; at the same time, during the initial film threading and maintenance adjustment, the left and right sealing rollers and the left and right ringed rollers also need to be opened.
