[0002] PP sheet not only has high transparency, good barrier properties, low density, non-toxic and hygienic, but is also recyclable. It does not produce toxic or harmful gases when heated or burned, does not harm human health, and does not corrode equipment. It is a new type of green and environmentally friendly packaging material.

[0003] The existing patent with publication number CN217968275U discloses a high-efficiency and energy-saving PP sheet extrusion production line, which relates to the technical field of PP sheet production equipment.

The driving device drives the oiling roller 3 to rotate, and the bottom end of the oiling roller 3 can dip silicone oil from the oiling tank 1. As the oiling roller 3 rotates, it can push the PP sheet body toward the drying box 5. At the same time, the silicone oil on the oiling roller 3 can The silicone oil on the PP sheet body is evenly applied to the bottom of the PP sheet body. When the PP sheet body passes through the drying box 5, the silicone oil applied to the PP sheet body is dried by the drying box 5, which is convenient for evenly applying the silicone oil. During the rotation of the oiling roller 3, the silicone oil remaining on the surface of the oiling roller 3 is removed by the scraper 12. The silicone oil slides down the inclined scraper 12 to the bottom filter 13, and the impurities or dust in the silicone oil are filtered through the filter 13. The filtered silicone oil falls into the oiling tank 1 for reuse, and at the same time, the impurities and dust are collected on the filter, which is convenient for cleaning impurities and dust.
