Description

Technical Field

[0001] The utility model relates to the technical field of magnetic stackers, in particular to a safety lifting device for magnetic stackers. Background Art

[0002] As is known, a magnetic stacker is a lifting device that absorbs products through a magnetic sling and completes the transfer and stacking of products through the cooperation of a walking mechanism and a lifting mechanism. However, since the surface of the product being absorbed has different flatness, during the process of the magnetic stacker absorbing the product and transferring it, the product may fall due to shaking or jittering, thereby causing safety accidents or damaging the stacked products, affecting the stacking efficiency.

[0003] The traditional solution is to increase the magnetic attraction of the magnetic lifter to strengthen the adsorption of the product. Although this method can ensure that the magnetic lifter can firmly adsorb all products, excessive magnetic force will interfere with the circuit in the control mechanism of the lifting equipment, causing problems with the equipment. In addition, high-power electromagnetic equipment will be magnetized after long-term operation. If demagnetization is not performed in time, the impact of the magnetic field on the equipment will increase, damaging the internal components of the equipment.

[0004] Therefore, in summary, there is a need in the market for a lifting device that can ensure the safety of the product during lifting without affecting the safety of the equipment through the magnetic force of the magnetic lifting device. Utility Model Content
