Abstract: A sleeve wrapping device includes a first fixing base, a second fixing base, a first supporting frame protruded from the first fixing base, a second supporting frame protruded from the second fixing base, a first roller mounted on the first supporting frame, a second roller mounted on the second supporting frame, and a sleeve wrapping film comprising a substrate and a plurality of adhesive layers. The first roller and the second roller move back and forth relative to the first supporting frame and the second supporting frame. The sleeve wrapping device is switched between a first state that the first roller and the second roller are in contact with each other and a second state that the first roller and the second roller are separated. The substrate winds the first roller and the second roller.

Abstract: A checking mechanism for workshop security applying a method for workshop security comprises a transmission device, a recording device, a storage subassembly and a control subassembly. The transmission device comprises a first end (115) and a second end (116). The recording device records personnel and objects in their possession through a security check process, to establish a correspondence. The storage subassembly stores the information comprising personnel and their objects. The control subassembly is used for controlling the recording device to record and store the information to the storage subassembly. The control subassembly can retrieve the information recorded by the recording device to detect a certain person’s correspondence to the certain object.
