Description
Technical Field
The invention belongs to the technical field of metal barrel stacking, and particularly relates to a metal barrel stack body film wrapping device and a film wrapping method capable of automatically feeding films.
Background
After the metal barrel (the open metal can is also called as a metal barrel) is manufactured, the metal barrel needs to be stacked up and down to save space, the process of stacking up and down is called stacking (also called stacking), and the stacked metal barrel is called a stack body. After stacking, in order to prevent the surface of the stack from scratching or soiling, and to prevent the stack from loosening, it is necessary to wind a film around the surface of the stack, a process known as wrapping. The plastic film used for wrapping the film is in a roll shape and is called a plastic film roll, and the plastic film roll comprises a cylindrical material core and a plastic film wound on the material core.
Before each stack body starts to wrap the film, the plastic film roll and the mandrel are required to be lifted to a vertical position close to the top of the stack body, the central axis of the plastic film roll is changed into the horizontal direction, the front end section of the plastic film is pulled to the position above the metal barrel at the top of the stack body, the front end section of the plastic film is flattened into a horizontal state, then the barrel mouth of the metal barrel at the top is covered, the process is called film feeding, after the film feeding, the plastic film roll with the central axis in the horizontal direction is slowly pulled into the vertical direction, then the plastic film roll and the mandrel are slowly descended, the stack body is driven to rotate continuously in the process, and then the film material is gradually wound on the stack body to achieve film wrapping. During film wrapping, the cylindrical material core of the plastic film roll is loosely matched and sleeved on a mandrel of the film wrapping equipment, the front end section of the plastic film is pulled due to the autorotation of the stack body, so that the material core and the plastic film roll rotate relative to the material core, and the film material of the plastic film roll is gradually unwound. After the wrapping, the plastic film needs to be cut, which is called film cutting, and the film cutting mechanism can be in the form of a mechanical cutter, a heating wire or a laser knife, and is a well-established technology, and is described in chinese patent documents such as CN205972072U, for example.
However, in the prior art, the film feeding step cannot be automated, and only manual operation by a worker is needed, namely, the worker pulls the front end section of the plastic film roll by hand to cover the upper end opening of the stack body, so that the efficiency is low, and the height of the stack body exceeds 2.5-3 meters generally, so that before each stack body is wrapped with the film, the worker is required to climb to a vertical position of 2.5-3 meters to perform the film feeding step, which is not only troublesome, but also dangerous.
