Description
Technical Field
The invention relates to metal foil production auxiliary equipment, in particular to a novel cathode roller grinding device.
Background
At present, in the production of metal foil, a method of continuous electrolysis using a cathode roll is generally used. The method is that a rotary cathode roller and an insoluble material are arranged in an electrolytic bath to make an anode, the bottom of the roller is soaked in electrolyte, metal (such as copper, aluminum and the like) in the solution is deposited on the surface of the roller to form metal foil after electrification, when the amount of the deposited metal foil reaches a certain scale, the metal foil is stripped, and then the metal foil is washed, dried and coiled, and then the surface treatment is further carried out.
When a metal foil is produced by an electrolytic method, the surface oxidation of the cathode roll is promoted by the penetration of an electrolytic solution and resistance heat after current carrying, and the state of the outer peripheral surface of the cathode roll is deteriorated. The roughness and shape of the outer surface of the cathode roll and the surface state of the cathode roll including impurities affect the quality of the metal foil to be produced. In order to restore the deteriorated outer surface state of the cathode roll to the original state, the outer surface of the cathode roll needs to be ground.
In the related art, the cathode roll grinding apparatus grinds the surface of the cathode roll using a grinding wheel having a rotation axis direction parallel to the rotation axis direction of the cathode roll and contacting the outer peripheral surface of the cathode roll, but there is a disadvantage that the work speed is slow when only one grinding wheel is used for grinding. In order to increase the working speed, a cathode roll grinding apparatus using a lengthened grinding wheel has begun to appear, however, as the axial length of the grinding wheel is lengthened, the radius of the grinding wheel in the direction of the rotating shaft is difficult to be processed uniformly, and a slight bending deformation may occur in the direction of the rotating shaft, resulting in an operation defect such as scratching of the surface of the cathode roll, and the like, so that the grinding quality is deteriorated.

In operation, when compressed air is injected into the cylinder body 153, the piston rod 154 protrudes away from the cylinder body 153, and the first direction lathe 150 moves along the first direction X to approach the cathode roll 10, so as to adjust the distance between the first grinding wheel 162 and the outer peripheral surface of the cathode roll 10, or adjust the contact pressure between the first grinding wheel 162 and the outer peripheral surface of the cathode roll 10. Although not limited thereto.

Furthermore, when the first grinding wheel 162 grinds the cathode roller 10 and scratches or other similar work errors occur, the operator can recognize the error and then urgently rotate the hand wheel 165 to make the first grinding wheel 162 deviate from the outer peripheral surface of the cathode roller 10, thereby preventing the dispersion of the grinding operation errors. Although not limited thereto.
The movement of the second polishing device 170 is the same as the first polishing device 130 in principle, and reference is made to the above description of the first polishing device for details, which are not repeated herein, and certainly not limited thereto.
In an embodiment of the present invention, each of the first polishing device 130 and the second polishing device 170 includes a driver for driving the first polishing wheel 162 and the second polishing wheel 187 to rotate.
Specifically, in the first polishing apparatus, a motor shaft of a drive motor 157 of a first polishing wheel 162 driver is coaxially connected to a pulley 158, a rotation shaft 161 of the first polishing wheel 162 is coaxially connected to a pulley 160, the drive motor 157 drives the pulley 158 to rotate, power is transferred to the pulley 160 through a belt, and the pulley 160 drives the first polishing wheel 162, which is coaxially connected, to rotate. Although not limited thereto.
The rotation principle of the second grinding wheel 187 is the same as that of the first grinding wheel 162, and the above description of the first grinding device is referred to for details, which is not repeated herein, and certainly not limited thereto.
In the embodiment of the present invention, the rotation axis of the second grinding wheel 187 is parallel to the rotation axis of the cathode roll 10. The annular outer peripheral surface of the second grinding wheel 187 is in contact with the outer peripheral surface of the cathode roll 10, that is, the second grinding wheel 187 is in line contact with the outer peripheral surface of the cathode roll 10. Although not limited thereto.
In the embodiment of the present invention, the rotation axis of the first grinding wheel 162 is parallel to or perpendicular to the rotation axis of the cathode roll 10.
Specifically, in the first combination of the embodiments of the present invention, when the rotation axis of the first grinding wheel 162 is parallel to the rotation axis of the cathode roller 10, the annular outer peripheral surface of the first grinding wheel 162 contacts with the outer peripheral surface of the cathode roller 10, that is, the first grinding wheel 162 contacts with the outer peripheral surface of the cathode roller 10 in a line, and both the first grinding wheel 162 and the second grinding wheel 187 contact with the outer peripheral surface of the cathode roller 10 in a line. On the one hand, the first grinding wheel 162 and the second grinding wheel 187 are in contact with the outer peripheral surface of the cathode roll 10, and the grinding operation is performed faster than the one grinding wheel operation, for example, the first grinding wheel 162 may be defined to grind the front half of the outer peripheral surface of the cathode roll 10, and the second grinding wheel 187 may be defined to grind the rear half of the outer peripheral surface of the cathode roll 10; on the other hand, when the first grinding wheel 162 and the second grinding wheel 187 are moved in the second direction Y, the first grinding wheel 162 and the second grinding wheel 187 are tangent to the outer peripheral surface of the cathode roll 10, and the tactile pressure is automatically and uniformly maintained, so that the grinding quality can be further improved. Although not limited thereto.
In the second combination of the embodiment of the present invention, when the rotation axis of the first grinding wheel 162 is perpendicular to the rotation axis of the cathode roll 10, the circular surface of the first grinding wheel 162 contacts the outer peripheral surface of the cathode roll 10, that is, the first grinding wheel 162 contacts the cathode roll 10 in a surface contact manner, and the second grinding wheel 187 contacts the outer peripheral surface of the cathode roll 10 in a line contact manner. On one hand, the first grinding wheel 162 and the second grinding wheel 187 are in contact with the outer peripheral surface of the cathode roll 10, and the grinding work is performed at a higher speed than the one grinding wheel work; on the other hand, the direction of the rotation axis of the first grinding wheel 162 and the direction of the rotation axis of the second grinding wheel 187 are perpendicular to each other, and the directions of the grinding textures formed during the grinding process are different, so that the first grinding wheel 162 and the second grinding wheel 187 are complementary to each other, and the ground cathode roll 10 has better surface gloss and higher quality; furthermore, when the first grinding wheel 162 and the second grinding wheel 187 move along the second direction Y, the first grinding wheel 162 and the second grinding wheel 187 are tangent to the outer peripheral surface of the cathode roller 10, and the tactile pressure is automatically and uniformly maintained, so that the grinding quality is higher. Although not limited thereto.
Meanwhile, the embodiment of the present invention is two polishing devices, but the present invention is not limited thereto, and three, four, etc. polishing devices may be provided, on which three, four, etc. polishing wheels in line contact with the outer periphery of the cathode roll 10 are provided; there may be a plurality of, for example, four, six, etc., polishing devices, and the polishing devices are provided with the same number of polishing wheels in line contact with the outer periphery of the cathode roll 10 and the same number of polishing wheels in surface contact with the outer periphery of the cathode roll. Although not limited thereto.
In the embodiment of the present invention, when the rotation axis of the first grinding wheel 162 is parallel to the rotation axis of the cathode roll, the rotation direction of the first grinding wheel 162 and the second grinding wheel 187 is opposite to the rotation direction of the cathode roll.
Specifically, when the rotation axis of the first grinding wheel 162 is parallel to the rotation axis of the cathode roll, the annular outer peripheral surface of the first grinding wheel 162 contacts the outer peripheral surface of the cathode roll 10, that is, the first grinding wheel 162 is in line contact with the outer peripheral surface of the cathode roll 10, and at this time, both the first grinding wheel 162 and the second grinding wheel 187 are in line contact with the outer peripheral surface of the cathode roll 10. When the first grinding wheel 162 and the second grinding wheel 187 rotate in the same direction as the cathode roll 10, for example, the first grinding wheel 162 rotates clockwise, the second grinding wheel 187 rotates clockwise, and the cathode roll 10 rotates clockwise, during the grinding process, the friction force of the contact area between the first grinding wheel 162 and the second grinding wheel 187 and the outer peripheral surface of the cathode roll 10 is increased, so that the possibility of generating the working error such as the scratch on the outer peripheral surface of the cathode roll 10 is increased. Although not limited thereto.
In the embodiment of the present invention, when the rotation axis of the first grinding wheel 162 is parallel to the rotation axis of the cathode roll 10, the axial length of the first grinding wheel 162 and the second grinding wheel 187 is less than 1/2 of the axial length of the cathode roll 10. That is, the lengths of the first grinding wheel 162 and the second grinding wheel 187 in the second direction Y are shorter than the lengths of the cathode roll 10 in the second direction Y, in which case, when there is a slight shape error within an acceptable range on the outer peripheral surfaces of the first grinding wheel 162 and the second grinding wheel 187, the possibility of occurrence of insufficient grinding or excessive grinding during the grinding process of moving the first grinding wheel 162 and the second grinding wheel 187 in the second direction Y is reduced, thereby improving the grinding quality. Although not limited thereto.
In an embodiment of the present invention, when the rotation axis of the first polishing wheel is perpendicular to the rotation axis of the cathode roll, the rotation direction of the second polishing wheel is opposite to the rotation direction of the cathode roll.
Specifically, when the rotation axis of the first grinding wheel 162 is perpendicular to the rotation axis of the cathode roll, the second grinding wheel 187 is in line contact with the outer peripheral surface of the cathode roll 10. When the second grinding wheel 187 rotates in the same direction as the cathode roll 10, for example, the second grinding wheel 187 rotates clockwise, and the cathode roll 10 rotates clockwise, the friction force of the contact area between the second grinding wheel 187 and the outer peripheral surface of the cathode roll 10 is increased during the grinding process, so that the possibility of generating operation errors such as scratches on the outer peripheral surface of the cathode roll 10 is increased. Although not limited thereto.
In the embodiment of the present invention, when the rotation axis of the first grinding wheel 162 is perpendicular to the rotation axis of the cathode roll 10, the diameter of the first grinding wheel 162 is smaller than 1/2 of the axial length of the cathode roll 10, and the axial length of the second grinding wheel 187 is smaller than 1/2 of the axial length of the cathode roll. That is, the lengths of the first grinding wheel 162 and the second grinding wheel 187 in the second direction Y are shorter than the lengths of the cathode roll 10 in the second direction Y, in which case when there is a slight shape error in an acceptable range on the outer peripheral surfaces of the first grinding wheel 162 and the above-described second grinding wheel 187, the possibility of occurrence of insufficient grinding or excessive grinding during the grinding process of moving the first grinding wheel 162 and the above-described second grinding wheel 187 in the second direction Y is reduced, thereby improving the grinding quality. Although not limited thereto.
In addition, each of the first grinding wheel 162 and the second grinding wheel 187 is composed of a cylindrical base formed of a fibrous material and a layer of elastic polymeric abrasive particles formed on a surface of the base. The cylindrical substrate made of the fiber material can be made of, for example, a polyvinyl alcohol (PVA) -based resin; the polymeric elastic abrasive particles can be made of, for example, a polyvinyl alcohol resin (PVA) -based resin, a polyurea-based resin, or a polyamide-based resin (acid-base resin). Although not limited thereto.
In the embodiment of the invention, more than two grinding wheels are used to contact with the peripheral surface of the cathode roller to grind the peripheral surface of the cathode roller, so that the grinding efficiency is greatly improved, and the working hours are shortened; meanwhile, the grinding wheels are matched for use, so that the problems of excessive grinding or insufficient grinding caused by small shape errors possibly existing on the surfaces of the grinding wheels on the surfaces of the cathode rollers can be solved, and the grinding quality is improved.
