Roller enhancing type strip packing machine

Abstract

The invention relates to a roller enhancing type strip packing machine. According to the moving direction of a film, the strip packing machine comprises a film coiling device, a film connecting device, a film feeding device, a color scale adjusting device, a middle cutting device, a former device, a longitudinal sealing device, a roller device, a transverse sealing device and a cutting device, wherein the film coiling device, the film connecting device and the film feeding device are arranged on the rear side of a rear plate. The front portion of the rear plate is provided with a front base plate, wherein the top ends of the rear plate and the front base plate are provided with top plates, and the front base plate is formed by an upper base plate and a lower base plate in a splicing mode.The color scale adjusting device and the middle cutting device are installed on the top plates, the former device, the longitudinal sealing device, the roller device and the transverse sealing deviceare sequentially arranged from top to bottom on the upper base plate, and the cutting device is installed on the lower base plate. According to the roller enhancing type strip packing machine, compared with the prior art, the roller device is arranged between the longitudinal sealing device and the transverse sealing device, so that the advantages of a roller and a sealing plate can be combined, opening sealing strength and sealing performance of a transverse sealing opening of a package bag is ensured, thus preventing leakage phenomena as well as improving the product yield.

Description

[technical field] [0001] The invention relates to the technical field of packaging machinery, in particular to a roller-enhanced strip packaging machine mainly used for forming, sealing and cutting packaging films, and then producing strip-shaped bag-making products. [Background technique] [0002] The sealing plate packaging machine has been widely developed and applied in the market because of its own advantages. Because the sealing plate of this kind of packaging machine is directly "closed", it is a kind of "surface" sealing, and the surface pressure of the sealed film is not strong, but because of the "long" time (compared to the roller type and other sealing method), for ordinary packaging, especially powder packaging, the sealing strength and airtightness are no problem, but for liquid, especially viscous packaging, the filling material is prone to "drawing" phenomenon, which is difficult Instantly extruded by the horizontal sealing plate, a "liquid film" or "oil fil...

Problems solved by technology

Because the sealing plate of this kind of packaging machine is directly "closed", it is a kind of "surface" sealing, and the surface pressure of the sealed film is not strong, but because of the "long" time (compared to the roller type and other sealing method), for ordinary packaging, especially powder packaging, the sealing strength and airtightness are no problem, but for liquid, especially viscous packaging, the filling material is prone to "drawing" phenomenon, which is difficult Instantly extruded by the horizontal sealing plate, a "liquid film" or "oil film" exists in the horizontal sealing seal of the packaging bag, or if the temperature of the sealing plate is too high, the liquid water in the "drawing" is easily vaporized to form Air bubbles, which can lead to insufficient airtightness of the packaging bag, which is prone to "leakage", affecting the shelf life of the product or causing pollution to the packaging bag
