Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a steel roller cleaning device. Background Technology

[0002] Slit extrusion coating is a common method used in the lithium battery industry for producing cell electrodes, offering advantages such as high coating speed, good coating uniformity, and a wide coating window. During high-speed coating with a die and steel roller, a cylinder propels the die close to the steel roller on the conveyor belt. The gap between the die lip and the foil varies from tens to hundreds of micrometers depending on the process. During slurry coating, foil tears or undried wet films can cause some slurry to adhere to the coating roller. If foreign matter is not cleaned from the roller surface promptly, it can lead to uneven electrode surface density or, in severe cases, foil tears and belt breakage, wasting both foil and slurry and requiring time for re-splicing, significantly impacting production efficiency.

[0003] The current cleaning method is manual cleaning, which is time-consuming, labor-intensive, inefficient, and costly.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Reference Figures 1 to 4 This application provides a steel roller cleaning device for use in the production of a slot extrusion coating machine. It includes mounting side plates 1, a coating steel roller 2, a cleaning roller 3, a waste container 4, and a rotary drive component. Two mounting side plates 1 are vertically erected and serve as the base of the device, supporting and mounting the various components. The coating steel roller 2, cleaning roller 3, and waste container 4 are all disposed between the two mounting side plates 1. The coating steel roller 2 is rotatably mounted on the mounting side plates 1. The cleaning roller 3 is disposed between the two mounting side plates 1 and can slide along the mounting side plates 1 in a direction close to or away from the coating steel roller 2. A translational drive component is provided on the mounting side plates 1, connected to the cleaning roller 3, for driving the cleaning roller 3 to approach or move away from the coating steel roller 2. The rotary drive component is connected to the driving side of the cleaning roller 3 to drive the cleaning roller 3 to rotate. The waste container 4 is installed between the two mounting side plates 1 and located below the cleaning roller 3 to collect foreign matter.

[0026] When the coating steel roller 2 needs to be cleaned, the translation drive drives the cleaning roller 3 to move towards the coating steel roller 2 until the roller surface of the cleaning roller 3 contacts the roller surface of the coating steel roller 2. Then, the rotation drive drives the cleaning roller 3 to rotate. The surface of the coating steel roller 2 is wiped clean by the friction between the roller surface of the cleaning roller 3 and the roller surface of the coating steel roller 2. Foreign objects that fall off during the cleaning process are collected by the waste box 4 for subsequent unified recycling and disposal.

[0027] Reference Figure 3 and Figure 4 During the cleaning process, the cleaning time of the cleaning roller 3 is controlled based on the rotational speed of the coating steel roller 2. For example, based on the rotational speed of the coating steel roller 2, the time it takes for the coating steel roller 2 to rotate one revolution is defined as one cleaning time for the cleaning roller 3. The driving cycle of the translational drive is then controlled so that it drives the cleaning roller 3 close to the coating steel roller 2 and interacts with it for one cleaning time before moving the cleaning roller 3 away from the coating steel roller 2. Then, at predetermined intervals, the translational drive drives the cleaning roller 3 close to the coating steel roller 2 again, repeating the above process to achieve intermittent cleaning. This effectively cleans foreign objects from the surface of the steel roller while avoiding the possibility of prolonged continuous friction damage to the surface of the coating steel roller 2. The cleaning time of the cleaning roller 3 interacting with the coating steel roller 2 can be adjusted as needed, such as one, two, or three cleaning times per cycle. The predetermined interval can also be set according to actual production needs and is not limited here.

[0028] Reference Figure 1 and Figure 2 Furthermore, the translation drive component is an ultra-thin cylinder 6, with two ultra-thin cylinders 6 respectively located at both ends of the cleaning roller 3, and the ultra-thin cylinders 6 are fixedly mounted on the corresponding mounting side plates 1. The ultra-thin cylinders 6 at both ends of the cleaning roller 3 operate synchronously to drive the cleaning roller 3 to move towards or away from the coating steel roller 2. The ultra-thin cylinders 6 can achieve precise position control and speed adjustment, which is beneficial for achieving intermittent cleaning of the cleaning roller 3.

[0029] In some embodiments, a sliding guide rail 11 is fixedly connected to the mounting side plate 1, extending horizontally along the mounting side plate 1. Slider blocks 12 are connected to both ends of the cleaning roller 3, and the sliders 12 are slidably connected to the sliding guide rail 11. The piston rod of the ultra-thin cylinder 6 is fixedly connected to the slider 12. The extension or retraction of the piston rod of the ultra-thin cylinder 6 causes the slider 12 to slide along the sliding guide rail 11, thereby allowing the cleaning roller 3 to move closer to or further away from the coating steel roller 2.

[0030] Furthermore, the rotation drive is a stepper motor 5, and the output shaft of the stepper motor 5 is connected to the drive end of the cleaning roller 3 to drive the cleaning roller 3 to rotate.

[0031] In this embodiment, the stepper motor 5 is fixedly mounted on the slider 12 located on the driving side of the cleaning roller 3. Rotary bearings (not shown in the figure) are connected to both ends of the cleaning roller 3, and the two ends of the cleaning roller 3 are rotatably connected to the sliders 12 on both sides via the rotary bearings. When the stepper motor 5 starts, it drives the cleaning roller 3 to rotate, thereby wiping and cleaning the coating steel roller 2. The stepper motor 5 is fixedly mounted on the slider 12. When the ultra-thin cylinder 6 drives the cleaning roller 3 to slide, the stepper motor 5 moves synchronously with the cleaning roller 3, ensuring the stability and reliability of the rotation drive of the cleaning roller 3.

[0032] Furthermore, the stepper motor 5 drives the cleaning roller 3 to rotate. The rotation direction of the cleaning roller 3 is the same as that of the coating steel roller 2, and the speed directions of the cleaning roller 3 and the coating steel roller 2 at the tangent point are opposite. In this embodiment, the coating steel roller 2 rotates clockwise under the drive of its drive mechanism, and the cleaning roller 3 also rotates clockwise under the drive of the stepper motor 5. This ensures that at the tangent point of the cleaning roller 3 and the coating steel roller 2, the speed direction of the coating steel roller 2 is downward while the speed direction of the cleaning roller 3 is upward, thus achieving a better cleaning effect. The opposite speed directions at the tangent point of the cleaning roller 3 and the coating steel roller 2 facilitate thorough wiping and cleaning of the surface of the coating steel roller 2 by the cleaning roller 3, thereby improving cleaning efficiency and ensuring a good cleaning effect.

[0033] Reference Figure 2 and Figure 3 In some embodiments, the cleaning roller 3 includes a rubber roller 31 and a cleaning cloth sleeve 32. The cleaning cloth sleeve 32 is fitted around the outer periphery of the rubber roller 31 and is used for rubbing and cleaning the coating steel roller 2. The cleaning cloth sleeve 32 can be a scouring pad, a non-woven fabric sleeve, etc., and is not limited to any particular type, as long as it can clean the surface of the coating steel roller 2 without damaging it. The cleaning cloth sleeve 32, fitted around the outer periphery of the rubber roller 31, is used to wipe and clean the coating steel roller 2. The cleaning cloth sleeve 32 is easy to clean, replace, and recycle, and the cleaning cloth sleeve 32, especially the scouring pad, provides excellent cleaning results without leaving any marks on the surface of the coating steel roller 2.

[0034] Furthermore, the steel roller cleaning device is also equipped with a humidification component 7, which is located inside the waste box 4. The humidification component 7 includes a pipe 71 and nozzles 72. Several nozzles 72 are evenly arranged on the pipe 71, and the nozzles 72 are positioned facing the cleaning roller 3. The pipe 71 is connected to a water supply device, and the nozzles 72 are used to spray water onto the surface of the cleaning roller 3, so that the cleaning cloth cover 32 on the surface of the cleaning roller 3 is always kept moist, so as to better wipe and clean the surface of the coated steel roller 2. Correspondingly, a drain outlet 41 is provided at the bottom of the waste box 4. The drain outlet 41 can be connected to a sewage pipe, sewage tank, etc., to collect and recycle the sewage in the waste box 4.

[0035] Furthermore, a scraper 8 is provided inside the waste box 4, and the blade of the scraper 8 can contact the surface of the cleaning roller 3. The scraper 8 is used to scrape off foreign objects from the surface of the cleaning cloth cover 32. Specifically, the scraper 8 is located below the cleaning roller 3. When the piston rod of the ultra-thin cylinder 6 retracts, the blade of the scraper 8 abuts against the cleaning cloth cover 32 on the surface of the cleaning roller 3. At this time, the stepper motor 5 drives the cleaning roller 3 to rotate, so that the scraper 8 scrapes off the foreign objects from the cleaning cloth cover 32 on the surface of the cleaning roller 3, cleaning the cleaning cloth cover 32. The foreign objects on the surface of the cleaning cloth cover 32 are scraped off by the scraper 8 and fall into the waste box 4. Setting the scraper 8 to clean the cleaning cloth cover 32 helps to extend the working time of the cleaning cloth cover 32 and reduce the replacement frequency of the cleaning cloth cover 32. The scraper 8 is used to clean the cleaning roller 3. Compared with the scraper 8 used to scrape the surface of the coating steel roller 2, the scraper 8 of this application does not directly act on the coating steel roller 2, which is beneficial to protect the coating steel roller 2 and avoid the possibility of the coating steel roller 2 being scratched by the scraper 8 during the cleaning process.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
