Winding film pre-tightening and automatic film taking-up device of winding packaging machine

Abstract

The invention relates to a winding film pre-tightening and automatic film taking-up device of a winding packaging machine. A body of the winding film pre-tightening and automatic film taking-up deviceis composed of a nut, a washer, an empty sleeve winding film roller, a coil spring, a winding film shaft, a driven friction plate fixing block, a driven friction plate, a driving friction plate, a driving friction plate fixing block, a thrust bearing, a pressure spring, a gasket, a fastening nut, a motor, a winding film, a driving friction plate shaft, a coupling and a key. According to the winding film pre-tightening and automatic film taking-up device, the problem that the winding film is too loose in the winding packaging process of an annular piece can be effectively solved, and the winding film can be pre-tightened and automatically taken up in real time so as to effectively improve the winding packaging quality of the annular piece; and two sets of schemes of coil spring pre-tightening and film taking-up and friction plate pre-tightening and film taking-up are adopted to be mutually matched to complete pre-tightening and film taking-up of the winding film, and the functions of pre-tightening and film taking-up can be completed separately through the two sets of schemes.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to a wrapping film pre-tightening and automatic film wrapping device of a wrapping wrapping machine. Background technique [0002] Wrapping machine is also called winding packaging machine, winding machine. The wrapping machine is to meet the packaging requirements of the containerized storage, transportation and mechanized loading and unloading of the goods. The current winding machines mainly include tray type winding machines, top pressure type resistance type winding machines, pre-stretch type automatic film winding machines and other types. , widely used in foreign trade export, food and beverage, canning, paper making, dyes, plastic chemicals, glass ceramics, electromechanical castings and other products in the package winding packaging. The working principle of the above-mentioned winding machine is to place the object to be wrapped in the center of the turntable, install ...

Problems solved by technology

Aiming at the fact that online shopping has become a popular shopping mode today, and the shapes and sizes of express parcels vary widely, the team of the present invention invented a method that can handle different shapes and sizes of ordinary pieces (cylindrical, rectangular, circular, etc.) and ring pieces. A multi-functional packaging machine for packaging commodities of different sizes and materials. The multi-functional packaging machine includes a vertical positioning clamping device for ring-shaped packages and a dual-mode wrapping packaging platform for ring-shaped and ordinary items, and a vertical positioning clamping device for ring-shaped packages. The invention team has applied for a national patent for the double-mode winding packaging platform of ring and ordinary parts. Mode winding packaging platform, ring and ordinary parts dual-mode winding packaging platform can not only wrap ordinary parts (cylindrical, rectangular, round, etc.) During the process, since the ring is not at the center of the stretch film rotation, the stretch film is in a tensioned state when the stretch film moves from the nearest to the farthest of the ring, but when the stretch film moves from the farthest to the nearest The stretch film is in a relaxed state. When the stretch film is in an excessively relaxed state, it will seriously affect the quality of the wrapping package.
