Description
Technical Field
[0001] The utility model relates to the technical field of corrugated cardboard packaging equipment, in particular to a simple corrugated cardboard film winding machine. Background Art
[0002] At present, corrugated cardboard is composed of a layer of wavy core paper and cardboard. It has a high mechanical strength and can withstand collisions and drops during handling. It is mainly used for manufacturing cartons.
[0003] After the corrugated cardboard is stacked, in order to prevent the corrugated cardboard from tipping over during handling, it is also necessary to pack the stacked corrugated cardboard. The existing packing methods are mostly completed by a film winding machine. Generally, a plastic film is wound around the periphery of the cardboard stack to form a protective film.
[0004] The existing film winding machine usually includes a frame, a turntable, a film unwinding mechanism, a pressing mechanism, a first lifting seat, a second lifting seat, a rotation driving mechanism capable of driving the turntable to rotate, a first lifting driving mechanism capable of driving the first lifting seat to lift, and a second lifting driving mechanism capable of driving the second lifting seat to lift; the rotation driving mechanism is installed on the frame, the turntable is rotatably installed at the bottom of the frame, the first lifting driving mechanism is installed on the frame, and the first lifting seat is liftably installed on the frame; the second lifting driving mechanism is installed on the frame, the second lifting seat is liftably installed on the frame, the film unwinding mechanism is installed on the second lifting seat and is located on one side of the turntable; the pressing mechanism includes a guide post and a pressing plate. The guide post is installed on the first lifting seat and extends vertically, and the pressing plate is installed at the lower end of the guide post and is located directly above the turntable. During packing, the cardboard stack is placed on the turntable, and the pressing plate of the pressing mechanism is pressed down to the top of the cardboard stack to press the cardboard stack tightly on the turntable. Then, the rotation driving mechanism drives the turntable to rotate, driving the film on the film unwinding mechanism to unwind, and packing the cardboard stack. However, since there are voids inside the corrugated cardboard and it is easy to deform, the pressing plate of the above pressing mechanism usually adopts a rigid fixed structure, and this pressing plate directly presses on the top of the corrugated cardboard, which is likely to cause excessive force and damage the top corrugated cardboard, or insufficient force resulting in the entire cardboard stack not being fixed and shifting, lacking a fine adjustment function for the position of the pressing plate. Summary of the Utility Model
[0005] The problem to be solved by the utility model is to provide a simple corrugated cardboard film winding machine that can elastically adjust the position of the pressing plate to adapt to cardboard stacks of different heights and densities and avoid damaging the corrugated cardboard.
