[0037] In this embodiment, when in use, the bottom plate 1 is first connected as a whole to the outlet of the film traction mechanism through multiple fixing plates 101 and bolts, and then the traction mechanism is used to gradually pull out the BOPA film so that the BOPA film is located between the two magnetic plates 104. Then the staff manually turns the knob 105, and the rotation of the knob 105 drives the bidirectional threaded rod 107 to rotate forward. As the bidirectional threaded rod 107 continues to rotate forward, the two sliders 108 located on the outer surface of the bidirectional threaded rod 107 begin to gradually drive the two magnetic plates 104 to move toward the two sides of the BOPA film. By turning the knob 105, the positions of the two magnetic plates 104 are adjusted so that they can fully absorb the iron filings on both sides of the BOPA film, and as the traction mechanism continues to pull, the iron filings on both sides of the BOPA film are completely cleaned off, thereby facilitating the simultaneous chip removal operation on both sides and improving the efficiency of iron chip removal.

[0038] Example 2, as Figure 1-Figure 4 As shown, one side of the outer surface of the two magnetic plates 104 is fixedly connected to a connecting plate 202, one side of the outer surface of the connecting plate 202 is fixedly installed with an electric telescopic column 203, the output end of the electric telescopic column 203 is fixedly connected to a scraper 204, and the other side of the outer surface of the two magnetic plates 104 is fixedly connected to a fixed block 2, the bottom of the fixed block 2 is clamped with an impurity collection box body 201, and the two magnetic plates 104 are square flat plates.

[0039] In this embodiment, after the chip removal operation is completed, the staff reverses the knob 105 to move the two magnetic plates 104 apart, then turns on the external power supply of the two electric telescopic columns 203, and uses the controller to start the two electric telescopic columns 203. The push rods of the electric telescopic columns 203 gradually push the scraper 204 to move horizontally on the magnetic surface of the magnetic plate 104, scraping the iron chips on its magnetic surface to the tail end of the magnetic plate 104, so that the iron chips fall into the impurity collection box 201. Since the impurity collection box 201 is clamped on the bottom of the fixed block 2, the staff can remove the two impurity collection boxes 201 containing iron chips as needed, and then pour out the iron chips, thereby facilitating the cleaning of the iron chips adsorbed on the surface of the magnetic plate without manual cleaning. It is very simple, saves time and effort, and improves the practicality of the iron chip elimination device for BOPA film production.

[0040] Working principle: When in use, first connect the bottom plate 1 as a whole to the outlet of the film traction mechanism through multiple fixing plates 101 and bolts, and then use the traction mechanism to gradually pull out the BOPA film so that the BOPA film is located between the two magnetic plates 104. Then the staff manually turns the knob 105. When the knob 105 rotates, it drives the bidirectional threaded rod 107 to rotate forward. As the bidirectional threaded rod 107 continues to rotate forward, the two sliders 108 located on the outer surface of the bidirectional threaded rod 107 begin to gradually drive the two magnetic plates 104 to move toward the two sides of the BOPA film. By turning the knob 105, the position of the two magnetic plates 104 is adjusted to fully absorb the iron filings on both sides of the BOPA film, and as the traction mechanism continues to pull, the iron filings on both sides of the BOPA film are completely cleaned off, thereby facilitating the simultaneous chip removal on both sides. The operation improves the efficiency of iron chip removal, and after the chip removal operation is completed, the staff reverses the knob 105 to move the two magnetic plates 104 apart, then turns on the external power of the two electric telescopic columns 203, and uses the controller to start the two electric telescopic columns 203. The push rods of the electric telescopic columns 203 gradually push the scraper 204 to move horizontally on the magnetic surface of the magnetic plate 104, scraping the iron chips on its magnetic surface to the tail end of the magnetic plate 104, so that the iron chips fall into the impurity collection box 201. Since the impurity collection box 201 is clamped on the bottom of the fixed block 2, the staff can remove the two impurity collection boxes 201 containing iron chips as needed, and then pour out the iron chips, so as to facilitate the cleaning of the iron chips adsorbed on the surface of the magnetic plate, without the need for manual cleaning, which is very simple, saves time and effort, and improves the practicality of the iron chip elimination device for BOPA film production.
