Pay-off rack provided with automatic pressure adjusting device

The utility model relates to the technical field of wire drawing equipment, in particular to a pay-off rack provided with an automatic pressure adjusting device. The pay-off rack comprises a wiring wheel, a wiring rod, a wiring rack and a material bobbin, wherein the material bobbin is arranged on the pay-off rack by an ejector pin cylinder and a driving shaft, a speed sensing controller is arranged on the pay-off rack and comprises a speed sensor, a controller and a braking device, wherein the speed sensor is arranged on the wiring rod close to the wiring wheel, the braking device is arranged on the driving shaft, and the speed sensor and the braking device are connected with the controller by a circuit. Compared with the prior art, the pay-off rack has novel and simple structure, and improves the performance of the metal wiring equipment; and by the speed sensing controller arranged on the pay-off device, the pay-off rack effectively controls the paying off tension of the wiring wheel, changes the paying off speed, enables the paying off speed to be steady, and further avoids serious consequences such as fall-off of steel wires from the wiring wheel, clamping and breaking of the steel wires, and the like.
