Grinding equipment for cathode roller

Abstract

The invention discloses grinding equipment for a cathode roller and belongs to the technical field of grinding equipment. According to the technical key point, the grinding equipment comprises a support arranged on the side edge of the roller surface of the cathode roller; guide rails are arranged on the support; an axial sliding seat is arranged on the guide rails and connected with a driving screw rod in a threaded mode; the driving screw rod is connected with a first driving motor, and the driving screw rod and the guide rails are arranged parallelly; supporting seats matched with the driving screw rod are arranged at the two ends in the length direction of the support correspondingly; the driving screw rod is connected with a displacement detecting mechanism; a radial sliding seat is movably arranged on the axial sliding seat and connected with a radial driving mechanism; an installing table is arranged on the radial sliding seat; a second driving motor is installed on the installing table in the axial direction of the cathode roller; and a power output shaft of the second driving motor is connected with a grinding wheel. The grinding equipment for the cathode roller is reasonable in structure, high in using safety, convenient to use and used for grinding the cathode roller.

Description

technical field [0001] The present invention relates to an auxiliary equipment for copper foil production, more specifically, it relates to a grinding equipment for cathode rollers. Background technique [0002] In the raw foil process of electrolytic copper foil, when the cathode roller is used for a certain period of time or when there is an abnormality on the roller surface, the cathode roller needs to be hoisted to a specific roller room for grinding. The grinding needs to be repeated several times, and the duration is several hours or even days. [0003] However, in the actual grinding process, manual observation and manual control of the grinding machine are still required to grind the cathode roll. In actual production, the applicant found that: due to the slow speed of the grinding platform, as used for the production of cathode rollers for very low-profile copper foil, the speed is only 4.2-5.5cm / min (0.7-0.92mm / s), At such low speeds, it is difficult for a human ...

[0003] However, in the actual grinding process, manual observation and manual control of the grinding machine are still required to grind the cathode roll

In actual production, the applicant found that: due to the slow speed of the grinding platform, as used for the production of cathode rollers for very low-profile copper foil, the speed is only 4.2-5.5cm / min (0.7-0.92mm / s), At such low speeds, it is difficult for a human to identify when the grinding table has stopped moving

Since the Ra of the cathode roller is very low, once the grinding platform stops moving due to various reasons (such as circuit failure, mechanical failure light), it will cause the circumferential direction of the grinding wheel to the cathode roller (the cathode roller keeps rotating) or the contact point (cathode roller When the rotation is stopped), excessive grinding will cause fatal damage to the roll surface of the cathode roll

In the same way, if the cathode roller stops rotating suddenly, it will cause excessive grinding of the axial direction (the grinding platform keeps moving) or the contact point (when the grinding platform stops running) of the cathode roller by the grinding wheel

Once the operator finds the above-mentioned abnormality, the roller surface has been seriously damaged, and the heavy-side cathode roller is directly scrapped; the slightly lighter one needs to be re-rolled repeatedly for a month, and the turning of the roller surface will not only reduce its service life by one-third Second, at the same time, the cost of repeated grinding for about one month will cost hundreds of thousands of yuan to make the cathode roller reapplied to production

[0004] However, in the current literature at home and abroad, there is no report on the damage caused by the grinder to the cathode roller grinding for the production of copper foil, and the device and method how to prevent this damage
