Description

Technical Field

[0001] The utility model belongs to the technical field of cathode rollers of foil making machines, and in particular relates to a polishing brush regrinding device for cathode rollers of foil making machines. Background Art

[0002] The cathode roller of the foil machine is a core component in the production process of electrolytic copper foil and plays a vital role. Its main function is to serve as the negative electrode in the electrolytic process to deposit copper ions to generate copper foil.

[0004] Although the problem of non-parallel propulsion of the single cylinder has been solved, there are still some problems in use. The pressure feedback of the polishing brush roller is not fast enough, and there is a lag in pressure regulation, which may cause the cathode roller to be damaged due to excessive pressure, or affect the polishing quality due to insufficient pressure. In addition, when the thickness of the cathode roller decreases due to continuous polishing, it is not possible to make immediate adjustments, and continued polishing is prone to excessive processing, which not only increases unnecessary losses in production, but also forces more manual intervention to monitor and adjust, reducing automation efficiency.

[0008] The regrinding mechanism also includes a screw rod rotatably connected to the middle part of the rear end of the support base, and the front end of the screw rod is threadedly connected to a thread hole arranged in the middle part of the rear surface of the sliding plate.

The pressure sensor 205 and the push rod 204 in 01 are respectively located in the spring 1 203 adjacent to the same side, and the pressure sensors 205 are electrically connected to the external single-chip computer. The lower end of the movable frame 202 is also provided with a scraping component, and the upper end of the movable frame 202 is also provided with a liquid adding component; the regrinding mechanism also includes a polishing brush roller 206 rotatably connected to the upper side of the front end between the left and right walls of the movable frame 202, and a motor 207 is provided on the front side of the upper end of the left surface of the movable frame 202. The right end of the output shaft of the motor 207 is fixedly connected to the left extension end of the polishing brush roller 206, and the motor 207 is electrically connected to the external single-chip computer; the regrinding mechanism also includes a screw rod 208 rotatably connected to the middle part of the rear end of the support base 100, and the front end of the screw rod 208 is threadedly connected to the thread hole set in the middle part of the rear surface of the sliding plate 200.

[0026] like Figure 1-4As shown, the scraping assembly includes a guide slot 300 which is laterally symmetrically arranged at the lower ends of the left and right walls of the movable frame 202, a scraper 301 is slidably connected between the two guide slots 300, and a spring 2 302 is provided on the rear wall of the guide slot 300, and the front end of the spring 2 302 is fixedly connected to the rear surface of the scraper 301; the scraping assembly also includes a guide rod 303 arranged on the rear wall of the guide slot 300, and the spring 2 302 is movably sleeved on the outside of the adjacent guide rod 303 on the same side, and the left and right ends of the rear surface of the scraper 301 are provided with sliding holes adapted to the guide rod 303.

[0027] like Figure 1-3 As shown, the liquid adding assembly includes a delivery pipe 501 arranged at the upper end of the moving frame 202, and nozzles 502 are provided in the liquid outlets uniformly arranged laterally on the outer arc surface of the delivery pipe 501.

[0028] The working principle of the polishing brush regrinding device for the cathode roller of the raw foil machine provided by the utility model is as follows: first, the relevant staff fixes the support base 100 and its auxiliary mechanism to the predetermined position of the regrinding of the cathode roller of the raw foil machine, and then the relevant staff rotates the screw rod 208, and the screw rod 208 rotates to drive the sliding plate 200 and its auxiliary mechanism to move toward the cathode roller of the raw foil machine. After the polishing brush roller 206 contacts the cathode roller of the raw foil machine, the polishing brush roller 206, the moving frame 202, the motor 207 and the push rod 204 overcome the elastic force of the spring 203 and move backward along the dovetail slide groove 201. When the pressure sensor 205 is turned on, the push rod 204 will contact the pressure sensor 205, and then the pressure sensor 205 detects the pressure value and transmits the data to the external single-chip computer. After reaching the pressure value, the relevant staff stops rotating the screw 208 to maintain the polishing pressure of the polishing brush roller 206 to avoid overpressure damaging the cathode roller or underpressure affecting the polishing effect. After the adjustment is completed, the relevant staff adjusts the operation of the motor 207 through the external single-chip computer, and the output shaft of the motor 207 rotates to drive the polishing brush roller 206 to rotate synchronously, so that the polishing brush roller 206 polishes the surface of the cathode roller of the foil machine. If the cathode roller is thinned due to polishing, the polishing brush roller 206, the movable frame 202, the motor 207 and the push rod 204 will move forward under the elastic force of the spring 1 203, so that the pressure applied by the push rod 204 to the pressure sensor 205 changes. After the pressure change reaches the set value, the external single-chip microcomputer controls the motor 207 to operate immediately, so as to avoid over-polishing of the cathode roller of the foil machine and reduce manual intervention. In this process, the scraper 301 will first contact the surface of the cathode roller of the foil machine, and apply appropriate pressure through the spring 2 302 to always fit the cathode roller of the foil machine. The surface of the pole roller can scrape off the residual copper waste when the cathode roller of the foil machine rotates, so as to avoid the influence of the polishing brush roller 206 on the polishing of the cathode roller of the foil machine, and at the same time, it can scrape off the metal chips or other waste generated in the polishing process. The external polishing liquid filling pump is connected to the delivery pipe 501, and the polishing liquid is pumped into it. The polishing liquid entering the delivery pipe 501 is sprayed to the polishing area through the nozzle 502, so as to ensure that the liquid evenly covers the polishing area, reduce heat generation, protect the cathode roller of the foil machine and improve the polishing efficiency, thereby improving the overall automation level and production efficiency.

[0029] like Figure 1-4 As shown, a guide groove 400 is provided at the front end of the upper surface of the scraper 301. The guide groove 400 is designed to guide the scraped waste materials and waste liquid to the collection system to keep the working area clean.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
