Winding film tape-casting production line

Abstract

The invention discloses a winding film tape-casting production line which comprises a feeder machine, a casting device, a thickness measurement device, a swing device, a drawing device, a winding device and an electrical control cabinet, wherein the feeder machine is provided with a plurality of plastic extrusion devices; a feeding end of one plastic extrusion device is provided with an offcut feeding device; one side of the casting device is provided with a mould device; discharge ends of all the plastic extrusion devices are respectively communicated with a mould head on the mould device; a discharge end of the mould device is connected with a feeding end of the casting device; a discharge end of the casting device is connected with a feeding end of the thickness measurement device; a discharge end of the thickness measurement device is connected with a feeding end of the swing device, a discharge end of the swing device is connected with a feeding end of the drawing device; a discharge end of the drawing device is connected with a feeding end of the winding device; a core-pulling device and a paper tube release unloading device are arranged at one side of the winding device. The winding film tape-casting production line has the advantages of being high in production efficiency, low in error of the thickness of the produced winding film, high in transparency and the like; a dry laminating method is adopted, and working procedures such as automatically packaging are available.

Description

technical field [0001] The invention relates to plastic film tape casting technology, in particular to a winding film tape casting production line. Background technique [0002] Stretch film, also known as elastic film or stretch film, is self-adhesive. It is a plastic film that can be stretched and wrapped tightly on one or both sides of the packaged goods. [0003] Stretching film can be divided into single-layer stretching film and multi-layer stretching film in terms of structure. Both sides of single-layer stretching film are sticky, and only one side of multi-layer stretching film is sticky, but multi-layer stretching film is conducive to improving product quality. Reduce production costs, the advantages are increasingly prominent. [0004] Most of the existing multi-layer stretch films are produced by blow molding machine blow molding method, which has the following disadvantages: 1. The thickness error of the film produced by blow molding machine method is relativel...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing multi-layer stretch films are produced by blow molding machine blow molding method, which has the following disadvantages: 1. The thickness error of the film produced by blow molding machine method is relatively large, The surface of the product is not clear during printing; 2. The product has low transparency and gloss; 3. The blow molding machine produced by blow molding method is easily affected by the external environment temperature, especially at the extruder head, when the melt temperature is too low , easy to block, resulting in production problems such as inability to extrude
