Magnetic roller device and magnetic dabber thereof

Abstract

The invention provides a magnetic roller device and a magnetic dabber thereof. The magnetic roller device comprises a dabber, a magnetic suction module, and an outer tube. The dabber is composed of a longitudinal axis and an outer peripheral surface, wherein the outer peripheral surface surrounds the radial side of the longitudinal axis. The outer peripheral surface is divided into a magnetic suction section and a non-magnetic section along the circumferential direction of the longitudinal axis. The magnetic suction module is arranged within the magnetic suction section and is composed of a pole arrangement. The pole arrangement of the magnetic suction module forms a Horbach array along the radial section of the dabber. The outer tube is sleeved on the outside of the dabber and the magnetic suction module. The outer tube is capable of rotating relative to the dabber and the magnetic suction module.

Description

technical field [0001] The invention relates to a magnetic roller device with an intensified magnetic field and its magnetic mandrel, in particular to a magnetic roller device and its magnetic mandrel for absorbing and separating metal scraps. Background technique [0002] The cutting of metal parts is often accompanied by the generation of a large amount of metal iron filings. In order to avoid the flying of metal iron filings from affecting the cutting operation of metal parts, during the cutting process, the surface of the metal parts will be washed with cutting fluid to make the metal scraps As the cutting fluid leaves the metal parts together, the stability and accuracy of metal parts cutting can be increased. [0003] Please refer to figure 1 As shown, in order to increase the reuse rate of the cutting fluid, generally the cutting fluid with metal filings 9 is introduced into a filter device 8 to separate the cutting fluid from the metal filings 9 . The filtering dev...

Problems solved by technology

[0006] However, when the plurality of magnetic pieces 822 are combined with the axis 821 in the above-mentioned manner, due to the lack of force to make the magnetic lines of force vertically deviate toward the outer surface of the outer tube 823, only two adjacent magnetic pieces 822 are separated. Part of the magnetic field lines pass through the outer surface of the outer tube 823, resulting in insufficient magnetic attraction force on the outer surface of the outer tube 823, which affects the magnetic attraction effect of the magnetic roller 82
