It is widely used as a carrier for tape or adhesive products, and is also used in the food and medical industries.

[0003] After searching, it is found that a Chinese patent document discloses a gluing device for release paper [Application number: 202121463546.2; Announcement number: CN 215235581 U]. This release paper gluing device includes a frame and a gluing component, the gluing component is installed above the frame, a negative pressure component is plugged into the surface of the frame, the negative pressure component includes an air suction hood, an air suction pipe and an induced draft fan, the air suction end of the induced draft fan is connected to the air suction hood through the air suction pipe, the air suction hood is symmetrically arranged on the upper surface of the frame, a preheating groove is opened in the middle of the upper surface of the frame, rubber plates and air guide holes are equidistantly arranged inside the preheating groove, the upper surface of the rubber plate is integrally formed with anti-slip grooves, and a preheating component is installed inside the frame. Spread the release paper on the upper surface of the frame, start the induced draft fan through an external power supply, generate negative pressure at the suction hood, absorb and fix the release paper, and the rubber strip at the open end of the suction hood and the rubber plate inside the preheating tank fit with the lower surface of the release paper, which not only facilitates fixation but also keeps the surface of the release paper smooth and improves the quality of glue coating.
