Film roll paying-off device

Abstract

The invention discloses a film roll paying-off device which comprises a supporting frame supporting two ends of a film winding roller and a film roll conveying part arranged in the supporting frame. Two mutually-parallel guide rails for guiding the film winding roller to roll is arranged on the supporting frame, the film roll conveying part comprises a mandrel arranged at the bottom of the supporting frame, two rotary arms, two shifting rods, a cross rod, a first extensile device and a second extensile device, wherein the two rotary arms and the two shifting rods are respectively and rotatably connected to two ends of the mandrel, two ends of the cross rod are respectively and fixedly connected with the rotary arms, the first extensile device and the second extensile device respectively drive the two rotary arms and two shifting rods to rotate around the mandrel, shifting forks protruding out of the outer edge of the supporting frame are arranged at the free ends of the two shifting rod, the free ends of the two rotary arms protrude out of the outer edge of the supporting frame, and first grooves supporting the film winding roller are formed in the protruded portions of the rotary arms. The film roll paying-off device has the advantages of being efficient, capable of saving effort, economic, safe and the like.

Description

technical field [0001] The invention relates to an unloading device, in particular to a device for unloading film rolls on a film blowing unit. Background technique [0002] With the application of thin films in daily life and industry more and more widely, the supply of thin films has been in short supply. While improving the process, film manufacturers are also considering how to shorten the time of each production step in order to improve efficiency and increase output. The current film is generally manufactured by a film blowing unit. The film blowing unit winds the film on the film roll for winding. After the winding is completed, the film roll needs to be unloaded from the film blowing unit; The weight is heavy, and a lifting trolley is needed when unloading the film roll, and at least two people are needed to assist at the same time, but the lifting of the lifting trolley takes time, and manual assistance also wastes manpower. There is also a danger of the film roll ...
