Description

Improved Removal of Foreign Material from Synthetic Resin Film The present invention relates to a device for removing foreign substances from a synthetic resin film, and more specifically, to an improved device for removing foreign substances from a synthetic resin film that automatically removes foreign substances including adhesives and rare earth elements remaining on a roll-type synthetic resin film, and facilitates the setting of the synthetic resin film on the device through a movable body configured in each of the primary and secondary foreign substance removal means and coupled to be movable in the vertical direction, and increases the efficiency of removing foreign substances and prevents cutting of the synthetic resin film by widening the contact area with the synthetic resin film by attaching silica sand, abrasive sand, or diamond sand to the outer surface of a plurality of rotary scrapers, and facilitates manufacturing and maintenance. Generally, substrates that control the operation of various electronic products such as LCD and PDP TVs, mobile phones, and digital cameras use printed circuit boards (PCBs) with metal wiring formed thereon having a designed pattern. Such printed circuit boards are manufactured by placing a roll-type PET (Polyethylene Terephthalate) film, installed to be supported on a workbench, onto the workbench, bonding multiple boards so that they are aligned and arranged on the PET film at regular intervals, and then performing a board manufacturing process including electrode formation. Here, the reason PET film is used in substrate manufacturing is that PET film, a synthetic resin film, facilitates insulation during the formation of electrodes on the substrate. When the manufacturing of the substrate as described above is completed, the finished substrate is separated from the PET film, the separated substrate is moved to the next process, the PET film used in the manufacturing of the substrate is wound onto a PET film recovery roller installed adjacent to the workbench described above, and then a new PET film is placed on the workbench to repeat the manufacturing process of the substrate described above. However, the PET film used in the manufacture of the aforementioned substrate is currently being discarded as general waste without being recycled, as foreign substances including the aforementioned adhesive remain on the film. However, since the aforementioned PET film must be disposed of through specialized agencies at enormous cost, it not only incurs unnecessary expenses but also results in the unnecessary waste of usable film materials, leading to a problem of doubly wasting costs and resources. In particular, most films are disposed of by incineration. However, even if the film is incinerated at high temperatures, the combustion of the film generates toxic gases and smoke, as well as a strong odor, which causes environmental problems such as polluting the air around the disposal site. To solve these problems, a foreign substance removal device has recently been developed and is being used to remove foreign substances adsorbed or attached to the surface of synthetic resin films for the purpose of recycling. For example, as illustrated in FIG. 1, Korean Published Patent No. 10-2024-0019955 (February 14, 2024), filed and disclosed by the applicant of the present invention, has been proposed as a device for removing foreign substances from a roll-type synthetic resin film, wherein a plurality of rotary scrapers rotate under the control of a control means to remove foreign substances from the upper and lower surfaces of the synthetic resin film, and water in a plurality of tanks is repeatedly supplied and recovered through a water supply means to recycle water, and the removed foreign substances are separated from the water and simultaneously separated into sediment and floating matter to induce recycling of rare earths while preventing the discharge of waste as well as recycling of the synthetic resin film, and water and foreign substances remaining on the synthetic resin film are removed through a water removal plate coupled at an angle in the vertical direction and then flowed into the tank. However, the above-proposed technology has the following problems: firstly, due to the rotary scraper having multiple pointed tips formed on the circumference, defects in the tips occur during manufacturing and wear occurs during use, causing gaps to form between the synthetic resin films during the process of removing foreign substances from the synthetic resin films, which reduces the efficiency of foreign substance removal or causes the synthetic resin films to be cut, resulting in the inconvenience of having to re-set the synthetic resin films in the device, and manufacturing and maintenance are difficult. Second, when performing a setting operation in which a roll-type synthetic resin film is positioned in a supply means (200) and the end of the synthetic resin film is positi
