The invention provides a movable cabinet, and belongs to the technical field of paper money arrangement. The movable cabinet comprises a pre-bundling banding machine module, a plastic packaging machine module and sliding modules, wherein the pre-bundling banding machine module and the plastic packaging machine module are rectangularly arranged; the bottom of the plastic packaging machine module has a protruding part; and the bottom surface of the pre-bundling banding machine module is connected with the top of the protruding part of the plastic packaging machine module in a sliding manner through the sliding modules. According to the movable cabinet, switch lock steel ball slide rails are arranged, so that the mobility of the modules is improved; a gap between the modules is narrowed through a fixture arranged at the upper parts of the modules, and the precision is improved; when the device needs to be maintained and/or repaired, a worker only needs to open the fixture arranged at the upper part of the device and latches on the switch lock steel ball slide rails, after operation, the pre-bundling banding machine module is pushed back to the original position along the slide rails, and the latches automatically return to lock the slide rails and the fixture; and the modules are connected through the lockable slide rails, so that the follow-up maintenance and/or repairing of the device is more convenient, and the safety of the device is higher.
