This utility model relates to the technical field of bag sealing and cutting equipment, and proposes a simple tape sealing machine suitable for supermarket and retail packing tables. The sealing machine consists of paired support plates forming a through-rotation groove at their upper ends. Rotatably mounted support components include a round shaft and a radial extension to support the tape roll. A vertical groove at the front end of the support plate serves as a restricted channel for feeding and cutting. On both sides of the channel are arranged a one-way ratchet stepping mechanism consisting of toothed pins / moving teeth and toothed wheels, and an embedded cutting mechanism consisting of a rocker arm blade holder, a pointed blade, and a return spring. A tailing bar with an arc-shaped protrusion and an auxiliary spring are provided on the other side of the blade holder to achieve overshoot assistance and anti-rebound. Optionally, a safety blade holder can be provided on the outside of the support plate for trimming / emergency cutting, and anti-slip rubber feet can be provided at the bottom to improve table stability.
