A protective treatment process for cutting and rolling of protective film

Abstract

The invention discloses a protection treatment process for protective film cutting and rolling, and specifically relates to the technical field of protective film cutting and rolling, which includes the following processing steps: Step 1, firstly collect the waste materials produced by the protective film processing, clean them up and arrange them for standby; step 2. Before cutting the processed and rolled protective film, determine the position of the cutting knife, and then wrap the protective film waste sorted in step 1 outside the protective film to be cut, and correspond to the position of the lower knife ;Step 3: After the lower knife position of the protective film is wrapped and thickened by the waste protective film, the roll cutting machine is turned on, and a circular blade is used on the roll cutting machine to carry out the roll cutting work. Thick protective film waste, after the waste is removed, the protective film wrapped by the waste is intact. The invention adopts the process of wrapping the protective film with the protective film waste and then cutting it into rolls. The protective film can be cut into rolls directly by using a round knife. It is simple and easy to operate during use, and the cut rolls of the protective film do not warp.

Description

technical field [0001] The embodiment of the present invention relates to the field of protective film cut-to-roll technology, and in particular to a protective treatment process for cut-to-roll protective film. Background technique [0002] When traditionally cutting PE protective film, it is necessary to replace the roll cutting knife. The sawtooth knife is used to cut the roll. It takes time to replace the cutter, and it needs to be recalibrated after replacement, which affects the cutting accuracy. Moreover, the sawtooth knife cuts rolls similar to saw grinding, which will cause loss ; When the circular knife is used to cut the PE protective film directly without replacing the serrated knife, the edge of the cut position of the protective film will be squeezed by the circular knife to cause warping, which will affect the quality of the protective film after cutting. [0003] Therefore, there is an urgent need to invent a protective film cutting and rolling protection tre...
