The servo motor 7 generally has a brake function, after the compression roller 2 moves downwards, the servo motor 7 can drive the compression roller 2 to rotate actively, and the single-sided adhesive tape can be smoothly attached to a material receiving point by matching with the conveying speed of the paper tape, so that the failure of secondary material receiving caused by the conditions of slipping and the like is not easy to occur. After the press roller 2 moves downwards, the servo motor 7 can brake immediately, and then the servo motor 7 automatically rotates to adjust the press roller 2 to move the next single-sided adhesive tape to the optimal position. Further optimize the setting, be equipped with one-way slewing mechanism between compression roller 2 and gear drive 6, can guarantee that compression roller 2 can only unidirectional rotation (clockwise) adjust, servo motor 7 can not select to carry out work when compression roller 2 rotates this moment. The unidirectional rotating mechanism is a unidirectional bearing 8.
