Guide rail lifting mechanism for vacuum bin of plasma cleaning machine

According to the guide rail lifting mechanism for the vacuum bin of the plasma cleaning machine, a support is fixed to the lower portion of the vacuum bin, a linear guide rail is vertically fixed to the left side wall of the support, the right end of a sliding block is connected to the linear guide rail in a matched mode, and two supporting seats connected with the linear guide rail in a matched mode are fixed to the support; a lifting driving device arranged on the left side of the linear guide rail and connected with the sliding block is supported on the support through a supporting base, and an upper sliding support is fixed to the sliding block and driven by the lifting driving device to move upwards through the sliding block moving upwards or downwards so that a bottom plate on the bottom face of the vacuum bin can be jacked upwards to be in a closed state. Or after the upper sliding support moves downwards and is separated from the vacuum bin, the bottom plate is opened. Smooth switching between the clo
