A vibration spring-pulling mechanism includes a horizontally arranged bracket, a conveyor belt used for conveying springs is installed on the bracket, an electro-vibration mechanism for dispersing spring vibration, a spring-pulling mechanism for pulling out the springs one by one and a spring clamping mechanism for preventing one spring from being pulled out when the adjacent spring is pulled out.The tightly accumulated springs enters from the front end of the conveyor belt, the electro-vibration mechanism is arranged right above the conveyor belt and transmits vertical vibration ro the springs, the spring clamping mechanism is arranged on the upper portion of the tail end of the conveyor belt, the spring-pulling mechanism is located on the rear side of the spring clamping mechanism, thespring clamping mechanism and the spring-pulling mechanism vertically stretch into the springs, the spring-pulling mechanism horizontally moves so as to pull the springs one by one, and actions of theconveyor belt, the electro-vibration mechanism, the spring-pulling mechanism and the spring clamping mechanism are all controlled by a control system. The mechanism can effectively sort out the tightly accumulated springs one by one, the whole process does not need manual participation, the spring separation efficiency is high, the production automation level of a spring mattress is improved, theoperation intensity in the production process is reduced, and the production efficiency is improved.
