Copper strip cleaning and drying apparatus

Abstract

This utility model discloses a copper strip cleaning and drying device, which relates to the field of copper strip production technology. The device includes a base plate, above which is a cleaning mechanism: a cleaning component for cleaning the copper strip; and a vibration component above the cleaning component. Vibration separates dirt from the copper strip. A scraper above the wastewater tank removes the wastewater absorbed by the cloth roller as it rotates, guiding it into the tank. This ensures the cloth roller maintains good absorbency, reducing residual water on the copper strip surface. A heating coil heats the copper strip after being energized, raising its temperature. Passing through the heating coil, the copper strip flows through the space between guide plates. The guide plates restrict the airflow direction generated by the fan, achieving directional dehumidification. This transforms the copper strip itself into a distributed heat source, compensating for the shortcomings of direct hot air in heat supply and humidity control, thus improving drying efficiency.

Description

Technical Field

[0001] This utility model relates to the field of copper strip production technology, specifically a copper strip cleaning and drying device. Background Technology

[0002] Copper strip is an important material for making batteries. The production process of copper strip includes cutting, grinding, and chamfering. During the processing, oil, dust, copper shavings and other contaminants will adhere to the copper strip. The copper strip needs to be cleaned before packaging.

[0003] The existing reference is Chinese utility model patent with announcement number CN215656591U, which discloses a copper strip cleaning and drying device, including a feeding roller, a feeding station, a spraying station, a scraping station, a wiping station, an ultrasonic cleaning station, a water shaking station, a drying station, and a receiving roller. The feeding station includes a feeding roller, the spraying station includes a spray nozzle, the scraping station includes a scraping wheel, the wiping station includes a first wiping roller, the ultrasonic cleaning station includes an ultrasonic cleaning tank and a second wiping roller, the water shaking station includes rollers, supports, a rotating support base, and springs, and the drying station includes a drying device. The material roll is loaded onto the feeding roller. The sprayer washes away large particles and debris, the scraper removes oil and small dust particles, the first wiping roller wipes away the oil, the second wiping roller wipes away stubborn stains, the water shaking station shakes the copper strip to shake off the cleaning solution, the drying device dries the copper strip, and the take-up roller rolls up the copper strip, thus improving the cleaning effect on the copper strip.

[0004] After cleaning, the aforementioned cleaning and drying device shakes off the residual cleaning solution on the surface of the copper strip. However, this method still leaves cleaning solution residue on the surface of the copper strip, affecting the drying efficiency in the subsequent drying process. In addition, the aforementioned cleaning and drying device uses hot air drying, which is inefficient and cannot quickly evaporate the moisture on the surface of the copper strip. Furthermore, it cannot filter the solid particles remaining in the tank during the cleaning process. After prolonged use, a large number of solid particles will remain in the tank, and these solid particles may be carried away from the cleaning tank by the copper strip, affecting the cleaning effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a copper strip cleaning and drying device that solves the problems of low drying efficiency and the impact of solid particle residue in the cleaning tank on the cleaning effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A copper strip cleaning and drying device includes a base plate, and a cleaning mechanism is provided above the base plate.

[0007] A cleaning assembly, positioned above the base plate, is used for cleaning copper strips;

[0008] A vibration component, positioned above the cleaning component, separates dirt from the copper strip through vibration;

[0009] A filter assembly, located below the cleaning assembly, is used to filter the cleaning solution;

[0010] The water removal assembly includes a support frame fixedly installed above a base plate, a connecting frame fixedly installed on the left side of the support frame, a drive motor fixedly installed on the left side of the connecting frame, a cloth roller movably installed above the support frame, a gear fixedly installed at the right end of the cloth roller, sewage tanks fixedly installed on the front and rear sides of the support frame, and a scraper fixedly installed above the sewage tank.

[0013] Preferably, the vibration assembly includes a limiting tube fixedly installed above the base plate, a spring fixedly installed inside the limiting tube, a movable frame movably installed above the limiting tube, a limiting block movably installed on the outer side of the movable frame, a linear bearing fixedly installed inside the limiting block, and a vibration motor fixedly installed above the movable frame.

[0014] Preferably, the filtration assembly includes a filter tank fixedly installed above the base plate, a partition plate fixedly installed inside the filter tank, a top cover installed on the top of the filter tank by bolts, a return pipe fixedly installed at the front end of the filter tank, a sewage pump fixedly installed at the rear end of the filter tank, and a circulation pipe fixedly installed at the inlet end of the sewage pump.

[0017] Beneficial effects

[0018] This invention provides a copper strip cleaning and drying device. Compared with the prior art, it has the following advantages:

[0019] (1) The copper strip cleaning and drying device, through the setting of the velvet roller, the shaft of the drive motor is fixedly connected to the left end of a velvet roller. When the drive motor drives the velvet roller to rotate, the velvet roller can drive another velvet roller to rotate through the gear to wipe both sides of the copper strip. The water absorption of the velvet removes the residual cleaning liquid on the surface of the copper strip. The scraper above the sewage tank scrapes away the sewage absorbed by the velvet roller when the velvet roller rotates and guides it into the sewage tank, so that the velvet roller can maintain good water absorption to reduce the amount of residual water on the surface of the copper strip. After the heating coil is energized, it heats the copper strip and raises the temperature of the copper strip. After passing through the heating coil, the copper strip will pass through the space between the guide plates. The direction of the airflow generated by the fan is restricted by the guide plates to carry out directional dehumidification, and the copper strip itself is transformed into a distributed heat source, which makes up for the deficiencies of direct hot air blowing in heat supply and humidity control, so as to improve the drying efficiency.

[0020] (2) The copper strip cleaning and drying device can divide the interior of the filter tank into multiple interconnected chambers by using a partition plate with an array of openings fixedly installed inside the filter tank. The cleaning liquid is graded and filtered by filling the filter tank with filter media with progressively smaller particle sizes from back to front. The filtered cleaning liquid will enter the inner cavity of the cleaning tank through the return pipe at the front side, so that the cleaning liquid flows from front to back inside the cleaning tank, thereby driving the dirt to move backward and causing the dirt to accumulate at the rear side of the cleaning tank, so that the sewage pump can extract the dirt, thereby achieving the effect of filtering the cleaning liquid.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a copper strip cleaning and drying device, including a base plate 1, and a cleaning mechanism 2 is arranged above the base plate 1.

[0030] A cleaning assembly 21 is disposed above the base plate 1 for cleaning copper strips. The cleaning assembly 21 includes a cleaning tank 211 fixedly installed above the base plate 1. Limiting rollers 212 are movably installed at the front and rear ends of the cleaning tank 211. An ultrasonic generator 213 is fixedly installed at the bottom of the cleaning tank 211. A movable plate 214 is movably installed inside the cleaning tank 211. Torsion springs 215 are fixedly installed at both ends of the movable plate 214.

[0031] Specifically, the base plate 1 restricts the position of the cleaning tank 211. The central cross-section of the cleaning tank 211 in the front-to-back direction is trapezoidal, allowing the copper strip to enter the cleaning tank 211 at a small angle to prevent excessive bending of the copper strip and affecting winding. The limiting roller 212 is also fixedly installed on the front and rear sides of the movable frame 223. The limiting roller 212 restricts the movement path of the copper strip, allowing the copper strip to be immersed in the cleaning liquid. The ultrasonic generator 213 can clean the dirt on the surface of the object through the cavitation, acceleration, and direct flow effects of ultrasonic waves in the liquid. The movable plate 214 can scrape off the cleaning fluid adhering to the upper surface of the copper strip. One end of the torsion spring 215 is inserted into the side wall of the cleaning tank 211, and the other end is inserted into the cylindrical structure at one end of the movable plate 214. The angle of the movable plate 214 is limited by the torsion spring 215 so that the movable plate 214 can rotate under the influence of the elastic force of the torsion spring 215 when the copper strip vibrates up and down, so that the bottom end of the movable plate 214 is always in contact with the upper surface of the copper strip. A silicone strip is provided at the bottom end of the movable plate 214, which can improve the scraping ability of the movable plate 214 to remove the cleaning fluid.

[0032] Vibration assembly 22, located above cleaning assembly 21, separates dirt from copper strip through vibration. Vibration assembly 22 includes a limiting tube 221 fixedly installed above base plate 1, a spring 222 fixedly installed inside the limiting tube 221, a movable frame 223 movably installed above the limiting tube 221, a limiting block 224 movably installed on the outside of the movable frame 223, a linear bearing 225 fixedly installed inside the limiting block 224, and a vibration motor 226 fixedly installed above the movable frame 223.

[0033] Specifically, the limiting tube 221 can restrict the bottom end of the movable frame 223 to always be in contact with the top end of the spring 222. One side of the limiting block 224 is fixedly connected to the outer side of the cleaning tank 211. The linear bearing 225 inside the limiting block 224 restricts the movement direction of the movable frame 223. When the vibration motor 226 at the upper end of the movable frame 223 is started, it will drive the movable frame 223 to vibrate up and down, causing the limiting rollers 212 on the front and rear sides of the movable frame 223 to drive the copper strip to move up and down, so that the copper strip can be separated from the surface dirt during the cleaning process.

[0034] A filter assembly 23 is disposed below the cleaning assembly 21 for filtering the cleaning liquid. The filter assembly 23 includes a filter tank 231 fixedly installed above the base plate 1. A partition 232 is fixedly installed inside the filter tank 231. A top cover 233 is bolted to the top of the filter tank 231. A return pipe 234 is fixedly installed at the front end of the filter tank 231. A sewage pump 235 is fixedly installed at the rear end of the filter tank 231. A circulation pipe 236 is fixedly installed at the inlet end of the sewage pump 235.

[0035] Specifically, the front end of the filter tank 231 is connected to the inner cavity of the cleaning tank 211 via a return pipe 234, and the rear end is connected to the inner cavity of the cleaning tank 211 via a sewage pump 235 and a circulation pipe 236. When the sewage pump 235 is started, the cleaning liquid inside the cleaning tank 211 can be transported to the filter tank 231 through the circulation pipe 236. The baffles 232 with an array of openings on their surface, which are fixedly installed inside the filter tank 231, can divide the interior of the filter tank 231 into multiple interconnected chambers. The filter media with progressively smaller particle size is filled from back to front to perform graded filtration of the cleaning solution. The filtered cleaning solution will enter the inner cavity of the cleaning tank 211 through the return pipe 234 at the front side, so that the cleaning solution flows from front to back inside the cleaning tank 211, thereby moving the dirt backward and causing the dirt to accumulate at the rear side of the cleaning tank 211, so that the sewage pump 235 can extract the dirt. At the same time, it can reduce the probability that the dirt will still adhere to the surface of the copper strip after being detached and will be carried away from the cleaning tank 211 with the movement of the copper strip.

[0036] The water removal assembly 24 includes a support frame 241 fixedly installed above the base plate 1. A connecting frame 242 is fixedly installed on the left side of the support frame 241, and a drive motor 243 is fixedly installed on the left side of the connecting frame 242. A cloth roller 244 is movably installed above the support frame 241, and a gear 245 is fixedly installed at the right end of the cloth roller 244. Sewage tanks 246 are fixedly installed on the front and rear sides of the support frame 241, and a scraper 247 is fixedly installed above the sewage tanks 246.

[0037] Specifically, the velour rollers 244 are linked by gears 245. The drive motor 243 is restricted to the left side of the support frame 241 by the connecting frame 242. The shaft of the drive motor 243 is fixedly connected to the left end of one velour roller 244. When the drive motor 243 drives the velour roller 244 to rotate, the velour roller 244 can drive the other velour roller 244 to rotate through the gears 245 to wipe both sides of the copper strip. The absorbency of the velour cloth removes the residual cleaning liquid on the surface of the copper strip. At the same time, the sewage tank 246 is fixedly installed on the front side of the velour roller 244 above the support frame 241 and on the rear side of the velour roller 244 below the support frame 241. The sewage tank 246 has drain ports at both ends. The scraper 247 above the sewage tank 246 scrapes off the sewage absorbed by the velour roller 244 when the velour roller 244 rotates and guides it into the sewage tank 246, so that the velour roller 244 can maintain good absorbency.

[0038] A drying assembly 25, located at the front end of the base plate 1, is used to dry copper strips. The drying assembly 25 includes a fixed tube 251 fixedly installed at the front end of the base plate 1. A heating coil 252 is fixedly installed inside the fixed tube 251. A guide plate 253 is fixedly installed on the front side of the fixed tube 251. Fans 254 are fixedly installed on both sides of the guide plate 253. The inner width of the fixed tube 251 is greater than the length of the limiting roller 212. The guide plate 253 is symmetrically installed at the front end of the fixed tube 251. The fans 254 are arranged in an array at the left and right ends of the guide plate 253 and are fixedly connected to the guide plate 253 by bolts. The air outlet direction of the fans 254 on the left and right sides of the guide plate 253 is the same.

[0039] Specifically, the fixing tube 251 can restrict the position of the heating coil 252 so that the copper strip can pass through the inside of the heating coil 252, so that the copper strip can be heated after the heating coil 252 is energized, causing the copper strip temperature to rise. After passing through the heating coil 252, the copper strip will pass through the space between the guide plates 253. The guide plates 253 restrict the direction of airflow generated by the fan 254 for directional dehumidification.

[0040] Specifically, the ultrasonic generator 213 is model DYW-35-G, the vibration motor 226 is model ZFB-3, the sewage pump 235 is model WQX12.5-40, the drive motor 243 is model EY410, and the fan 254 is model SA20060H220B. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] During operation, the shaft of the drive motor 243 is fixedly connected to the left end of a cloth roller 244. When the drive motor 243 drives the cloth roller 244 to rotate, the cloth roller 244 can drive another cloth roller 244 to rotate via the gear 245, thus wiping both sides of the copper strip. The absorbency of the cloth removes residual cleaning solution from the surface of the copper strip. The scraper 247 above the wastewater tank 246 scrapes away the wastewater absorbed by the cloth roller 244 as it rotates and guides it into the wastewater tank 246, allowing the cloth roller 244 to maintain good absorbency and reduce the amount of residual water on the surface of the copper strip. After being energized, the heating coil 252 heats the copper strip, causing its temperature to rise. After passing through the heating coil 252, the copper strip passes through the space between the guide plates 253, which restrict the flow of the fan 2. 54 generates airflow in a directional manner to dehumidify, transforming the copper strip itself into a distributed heat source. This compensates for the shortcomings of direct hot air blowing in terms of heat supply and humidity control, thereby improving drying efficiency. The filter tank 231 is divided into multiple interconnected chambers by a partition 232 with an array of perforations fixedly installed inside the filter tank 231. The cleaning solution is graded and filtered by filling the filter tank 231 with filter media of progressively smaller particle size from back to front. The filtered cleaning solution will enter the inner cavity of the cleaning tank 211 through the return pipe 234 at the front side, causing the cleaning solution to flow from front to back inside the cleaning tank 211. This causes the dirt to move backward and accumulate at the rear side of the cleaning tank 211, so that the sewage pump 235 can extract the dirt, thus achieving the effect of filtering the cleaning solution.
