Specifically, as shown in fig. 8, the grabbing cylinder 52 drives the rack 53 to move downward, and the rack 53 drives the gear 54 to rotate, so as to drive the two clamping jaws 51 to open, thereby leaving a space for the electromagnet 4 to suck the steel bar 100 to be fed; as shown in fig. 9, the grabbing cylinder 52 drives the rack 53 to move upwards, and the rack 53 drives the gear 54 to rotate, so as to drive the two clamping jaws 51 to fold and grab the steel bar 100 to be fed, which is sucked on the electromagnet 4. In order to solve the problem that there is the contained angle to lead to magnetism to inhale the effect poor in the extending direction of waiting to feed reinforcement 100 and electromagnet 4, can design into the arc recess form along its extending direction with electromagnet 4's bottom surface, electromagnet 4 inhales the in-process of waiting to feed reinforcement 100 and treats that feed reinforcement 100 can the automatic deflection direction, or loading attachment's fixed baseplate 2 can the automatic deflection direction, thereby eliminate the contained angle between the extending direction of waiting to feed reinforcement 100 and electromagnet 4's the extending direction, guarantee that magnetism suction can all obtain the application, magnetism suction effect is better.

Two sets of grabbing devices are installed respectively at the both ends of electro-magnet 4 to can firmly hold two positions of being inhaled treating material loading reinforcing bar 100 on electro-magnet 4, make treating material loading reinforcing bar 100 more stable in the in-process of being carried, can not fall down from electro-magnet 4 midway.

The specific installation manner of the gripping device is not limited, preferably, the gripping cylinder 52 is fixedly arranged at the end of the electromagnet installation base 3, the rack 53 is connected to the output end of the gripping cylinder 52 and is located on the axis extension line of the electromagnet 4, the two gripping jaws 51 are symmetrically arranged on the left side and the right side of the rack 53, the gear 54 is meshed with the rack 53, and when the gripping cylinder 52 drives the rack 53 to reciprocate up and down, the two gripping jaws 51 can be opened or closed.

On the basis of the structure, the bottom end of the clamping jaw 51 is provided with a one-way bearing 56, and the outer side of the one-way bearing 56 is sleeved with a one-way rotating hand wheel 57. Because of the function of the one-way bearing 56, the one-way rotating hand wheel 57 can only rotate in one direction (clockwise or counterclockwise), and as long as the stress direction of the steel bar 100 to be loaded when the clamping jaws 51 are adjusted to hold the steel bar 100 to be loaded is opposite to the rotating direction of the one-way rotating hand wheel 57, the clamping jaws 51 can be stable and reliable when clamping the steel bar 100 to be loaded.

The peripheral wall of unidirectional rotation hand wheel 57 designs into the arc, can more laminate on treating the outer peripheral face of material loading reinforcing bar 100 after holding together, treats that the fixed effect of material loading reinforcing bar 100 is better.
