This utility model relates to the field of waste removal technology for printing machines, specifically to a waste removal device for a label printing machine, including a mounting frame, a winding mechanism, and an auxiliary mechanism. The winding mechanism includes a rotating plate rotatably mounted on the mounting frame and two winding rollers rotatably mounted on the rotating plate. The auxiliary mechanism includes a sliding block, a tension spring, a cutter box, a sponge pressing block, a cutter plate, a sliding assembly, and a limiting assembly. The sliding assembly includes a guide groove, a second guide rod, a second spring, a counterweight rod, and a guide slide rod. When the front winding sleeve is full, the rotating plate rotates to switch the rear empty sleeve to the front working position and, in conjunction with the auxiliary mechanism, cuts the waste material without stopping the machine to change the roll. Before cutting the label waste, the sponge pressing block presses the waste material, causing the corner waste material to adhere to the winding sleeve, preventing the waste material from shifting during cutting and ensuring a flat cut. Under the guidance of the guide slide rod and the guide groove, the counterweight rod drives the cutter to slide and cut the corner waste material under the action of inertia, improving the cutting efficiency.

This invention discloses a seamless switching positioning method integrating RTK and PPP-RTK algorithms. This method achieves seamless switching between RTK and PPP-RTK algorithms by designing a dual-state model within a Kalman filtering framework. When network connectivity is available, the system automatically uses NRTK corrections to achieve high-precision RTK positioning; when the network is interrupted, the system seamlessly switches to satellite-based PPP-RTK corrections for PPP-RTK positioning without requiring a software restart.
