Thin film corner cutting packing process and packing machine

Abstract

The invention discloses thin film corner cutting packing process and a packing machine which are used for packing a rectangular object to-be-packed through a single layer of film. The object to-be-packed is provided with two opposite side faces, and four continuous peripheral faces are arranged between the two side faces. The process comprises the following steps: S100, wrapping the thin film on the four peripheral faces of the object to-be-packed; S200, spreading the thin film on the two side faces along the middles of the respective faces; S300, cutting off the spread thin film; S400, cutting off the thin film corners at the connecting positions of the four peripheral faces. The packing machine comprises a supporting and spreading conveying unit, a push unit, a primary hot cutting unit, a film spreading unit, a secondary hot cutting unit and a corner cutting unit, wherein the push unit, the primary hot cutting unit, the film spreading unit, the secondary hot cutting unit and the corner cutting unit are arranged in sequence. The packing machine is suitable for the thin film corner cutting packing process. The thin film corner cutting packing process and the packing machine are high in packing efficiency and good in quality and generality.

Description

technical field [0001] The invention relates to the field of film packaging, in particular to a film corner-cutting packaging process and a packaging machine. Background technique [0002] In order to protect the product from being scratched and damp, and to beautify the appearance of the product, it is necessary to wrap a layer of plastic film on the outer surface of the product package and cut off the four corners. [0003] At present, the traditional process of cutting the corners of the package is mainly to use a double-layer film packaging machine to cut the corners of the film packaging of the product. The traditional process is as follows: [0004] First, the double-layer film is made into a packaging bag with one end open and sent to the packaging station; then, the package is pushed into the prepared packaging bag. Then, the sealing mechanism seals the opening end of the packaging bag, and then cuts the corners; finally, the sealed package is sent out through the d...

AI Technical Summary

Problems solved by technology

When cutting the corners of packages of different volumes and shapes, the corner cutting mechanism cannot perform lifting movements to cut off the film corners of packages of different heights. This kind of packaging machine has poor versatility and is not conducive to popularization.

[0007] Third, when using this process or packaging machine for packaging, it will be time-consuming, laborious, and increase the production cost; it is not suitable for large-scale production, and its application range is small

[0008] Therefore, traditional craftsmanship and packaging opportunities affect the economic benefits of enterprises, cannot meet the needs of the market, and cannot fully meet the needs of modern industrialization
