Multi-column strip vertical packing machine

Abstract

The invention relates to a packing machine which comprises a framework, a film supply device, a film feeding device, a feeding hopper, a plurality of collar forming devices, a horizontal sealing device, a plurality of vertical sealing devices, a slitting device, a detection device and a separation device. The horizontal sealing device comprises two upright guide rails, two sliders, two cylinders, two touch cylinders, front pressing pieces, rear pressing pieces and a support, and the two sliders are matched with the guide rails; the two sliders are respectively mounted on the two guide rails, and inner sides of the two sliders are fixedly connected with the support; outer sides of the two sliders are respectively connected with telescopic arms of the two cylinders, the front pressing pieces are fixedly mounted on telescopic arms of the two touch cylinders, and the two touch cylinders are fixedly mounted on the front side of the support. The packing machine in a multi-column design has the advantages that the production efficiency is greatly improved, a mechanical structure is simplified, and the product percent of pass is guaranteed owing to the additional detection device and the additional separation device.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a multi-row strip vertical packaging machine. Background technique [0002] In the prior art, during the packaging process of the packaging machine, the film-moving device first needs to transfer the film. In the prior art, the film-moving device transfers the packaging film on it to the next station, and the cutting device needs to adjust the size of the film. Slitting on demand, because the packaging film used as packaging is usually large in size during transmission, and its width needs to be slit first, so it is necessary to set up a slitting knife mechanism. Then the packaging film processed by the bag forming mechanism will enter the horizontal sealing mechanism after passing through the vertical sealing mechanism. The function of the horizontal sealing mechanism is mainly to seal the packaging film in the horizontal direction. After the steps of longitudinal sealing and horizontal ...

AI Technical Summary

Problems solved by technology

The traditional film-drawing device generally adopts a vacuum film-drawing device. This vacuum film-drawing device must be installed under each vertical sealing device, and each vacuum film-drawing device must be equipped with a vacuum pump. If this film-drawing device is applied to multiple The cost is too high and the structure is complicated on the column type strip vertical packaging machine

Moreover, the current multi-row strip vertical packaging machine generally does not have a detection device for detecting whether the material is put into the packaging bag, and lacks a device that can separate the unqualified product from the qualified product after the unqualified product is detected. separation device
