Description

Automatic wrapping equipment for wrapping steel coils

This new model relates to an automatic wrapping equipment, in particular to an automatic wrapping equipment for wrapping steel coils.

In the quenched and tempered recoiling line of a steel plant or similar production lines that can produce steel coils, after the steel coils are produced, the steel coils must be packaged with an automatic wrapping machine to maintain the original shape of the product steel coils and prevent There is a danger that the steel coils will loose and bounce off during handling.

Referring to FIG. 1, the conventional automatic wrapping machine 1 uses compressed air as kinetic energy to make the pneumatic motor 11 drive the wrapping steel belt 13 on the unwinding disc 12 to perform the packaging operation. The unwinding disc 12 rotates clockwise to take out the belt, or counterclockwise to take up the belt, and the movable swing arm 14 provided on the unwinding disc 12 controls the direction of rotation. When the packaging is started, the pneumatic motor 11 pulls the wrapping steel belt 13 so that the movable swing arm 14 moves in the direction of the wrapping machine head 15 to trigger the pneumatic valve 16 to switch in the forward rotation direction, so that the pneumatic gas can be sent out to make the The unwinding disc 12 rotates in the forward direction to send out the wrapping steel band 13. After the dressing steel belt 13 is threaded, the pneumatic motor 11 starts the dressing steel belt 13 to pull back, so the movable swing arm 14 will move away from the dressing head 15 to trigger the pneumatic valve 16 to control The unwinding disc 12 is reversed to retract the wrapping steel band 13 into the unwinding disc 12. When the wrapping steel belt 13 tightens the steel coil 2, the wrapping head 15 performs a clamping and cutting action to complete the packaging.

As mentioned above, when the bandaging machine 1 is pulling the belt, the pneumatic motor 11 is active, and the unwinding disk 12 is passive. During the unwinding and unwinding process of the bandaging steel belt 13, the air motor 11 must pass through the The movement of the movable swing arm 14 controls the directionality of the air pressure valve 16 so that the unwinding disc 12 can operate normally. However, because the unwinding disc 12 is passive, occasionally, the strapping steel belt 13 may loosen and jam. When the bandaged steel belt 13 loosens the material, the loose bandaged steel belt 13 will jam the shield 17, which not only increases the difficulty of handling, but also increases the risk of personal injury. Furthermore, when replacing/re-installing the bandaging steel belt 13, although the personnel will turn off the power supply of the bandaging machine 1, the unwinding disc 12 still has air pressure kinetic energy, thus forming an unsafe state. Therefore, it is necessary to find a solution.
