Automatic four-axis cast film winding machine

Abstract

The invention provides an automatic four-axis cast film winding machine. The automatic four-axis cast film winding machine is provided with a plurality of expansion shafts, the expansion shafts at different positions can carry out tube sleeving, cast film winding, roll moving-out and standing for cooling down correspondingly, the expansion shafts are driven by a motor to change positions to realize function switching of the plurality of expansion shafts, so that not only the tube sleeving, cast film winding and roll moving-out processes of the expansion shafts can be separated to be independent to save the cast film winding time, but also the expansion shafts can be left to stand for cooling down after working so as to prolong the service lives of the expansion shafts and an expansion shaft installation assembly; and in the meanwhile, a paper tube conveying assembly and a paper tube sleeving assembly are independent from an expansion shaft winding structure, so that paper tubes can bearranged and subjected to tube sleeving while cast films are wound around the expansion shafts, and the winding working time is shortened. A defective product returning assembly of the winding machinecan move damaged paper tubes which cannot sleeve the expansion shafts out of the internal structure of a winding machine body, so that the internal structure of the machine body is stabilized and thestability and safety of the cast film winding process are ensured.

Description

technical field [0001] The invention relates to the technical field of cast film machines, in particular to a four-axis automatic cast film winder. Background technique [0002] During the transportation and storage of the paper tube, it is inevitable that the paper tube cannot be installed on the inflatable shaft due to damage and deformation. If the deformed paper tube is forcibly installed on the air shaft, it may not only cause damage to the structure of the paper tube or the air shaft due to pressure, but also affect the winding of the cast film or the quality of the finished product during the winding process of the cast film. It is also easy to produce safety accidents when the paper tube is off the shaft. [0003] At the same time, the current casting film winding method often adopts a single rotation winding of a winding roller or an air expansion shaft. The single winding method of the rewinding roller is easy to cause the problem that the rewinding roller rubs t...

AI Technical Summary

Problems solved by technology

The single winding method of the rewinding roller is easy to cause the problem that the rewinding roller rubs the cast film and causes the cast film to be damaged, while the single winding method of the air expansion shaft is easy to stretch the cast film and form ribs on the cast film surface. Poor winding effect

[0004] In the existing technology, there is still a single-threaded operation in the process of winding the cast film of the paper tube, and the paper tube needs to perform the processes of arrangement, casing, winding and unwinding in sequence, and only the internal structure of the single process is modified It is also impossible to effectively improve the winding speed of the cast film

Repeated rewinding of the air shaft in the paper tube set will also easily cause the temperature of the air shaft to rise after prolonged use, reducing the service life of the air shaft and the installation components of the air shaft
