1. Introduction

    In the battery manufacturing industry, batteries play a crucial role in rolling machines. It is mainly used for rolling, compressing, and shaping battery electrodes to ensure uniform distribution and tight compaction of the electrodes, thereby improving the efficiency, capacity, and safety of the battery. The design of battery roller machines is usually based on precise mechanical principles and advanced control systems to achieve precise treatment of electrodes.

2. Types and configurations of battery roller machines

2.1. Horizontal battery roller machine:

    This type of machine adopts horizontally arranged roller shafts, suitable for large-scale production, and has high throughput.

Usually equipped with an automatic feeding system, it can continuously feed electrodes into the roller shaft for processing.

The clearance and pressure of the roller shaft can be adjusted through a precise control system to meet the processing needs of different electrodes.

2.2. Vertical battery roller machine:

    The vertically arranged roller shaft makes the machine more compact and suitable for handling smaller or special shaped electrodes.

Vertical layout also helps to reduce material waste and dust pollution.

It also has a precise control system to ensure the accuracy and consistency of electrode processing.

2.3. Multi stage battery roller machine:

    By combining multiple roller shaft stages, multiple rolling and compression of the electrodes are achieved to achieve higher electrode density and uniformity.

Multi stage design allows for the application of different pressures and speeds at different stages to meet the processing needs of different materials.

Usually equipped with advanced monitoring systems for real-time monitoring of electrode quality and processing.

3. Operation steps of battery roller machine

3.1 Preparation stage:

    Check if the machine is in good condition, including the roller shaft, transmission system, control system, etc.

    Clean up debris and dust inside and outside the machine to ensure a clean working environment.

    Prepare the electrode materials to be processed and check if their quality and specifications meet the requirements.

3.2 Start up:

    Press the power button to start the control system of the battery on the roller machine.

According to the characteristics of electrode materials and processing requirements, set appropriate parameters such as roller shaft clearance, pressure, and speed.

Check if the machine is running properly and perform necessary preheating or calibration operations.

3.3 Electrode processing:

    Feed the electrode material between the roller shafts to ensure that the electrodes are evenly distributed and tightly adhere to the surface of the roller shaft.

Start the roller shaft rotation to roll and compress the electrodes. During the processing, closely monitor the changes in the electrodes and adjust parameters as needed.

After processing, remove the electrode from between the roller shafts and conduct a preliminary quality inspection.

3.4 Quality inspection:

    Conduct a detailed quality inspection on the processed electrodes, including thickness, density, uniformity, and other indicators.

Use professional equipment to measure and analyze electrodes to ensure they meet product standards and customer requirements.

Mark and record the unqualified electrodes, and take corresponding treatment measures.

3.5 Cleaning and maintenance:

    After each processing is completed, promptly clean the residues and dust inside and outside the machine.

Regularly inspect the wear and damage of components such as roller shafts, transmission systems, and control systems, and carry out necessary repairs and replacements.

Regular maintenance and upkeep of the machine to extend its service life and maintain stable performance.

4.  Safety precautions

4.1 Wear protective equipment: When operating the battery roller machine, protective gloves, goggles, and earplugs must be worn to prevent accidental injury.

4.2 Adhere to operating procedures: Strictly follow the operating procedures and do not change parameters or engage in illegal operations without authorization.

4.3 Keep the machine clean: Regularly clean the internal and external residues and dust of the machine, and maintain a clean and orderly working environment.

4.4 Regular inspection and maintenance: Regularly inspect and maintain the machine to ensure its normal operation and stable performance.

4.5 Emergency stop: In the event of an emergency or machine malfunction, the emergency stop button should be immediately pressed and the power should be cut off to ensure the safety of personnel and equipment.

5. Application range

    Battery roller crusher, also known as double roller crusher or roller crusher, has a wide range of applications. Firstly, battery roller machines (especially lithium battery roller machines) play an important role in the battery industry, mainly used in the production process of electronic products such as lithium-ion batteries, polymer lithium-ion batteries, and solid-state batteries. Its main function is to combine and fix the positive and negative electrodes of the battery cell through the rolling process. Different types of battery cells require different roller presses because they require different rollers and roller pressures.

    De plus, les presses à rouleaux à batterie (ou plus généralement les presses à rouleaux) sont également largement utilisées dans des industries telles que la chimie et l'électronique. Dans l'industrie chimique, les presses à rouleaux peuvent être utilisées pour le traitement par extrusion des matières premières afin de répondre aux exigences requises du processus. Surtout dans l'industrie des batteries, la presse à rouleaux spécifique aux batteries est spécialement conçue pour le processus de laminage des batteries lithium-ion. En raison de la haute précision requise pour le laminage des plaques polaires, la presse à rouleaux doit avoir des caractéristiques telles qu'une dureté élevée, une pression uniforme, un réglage facile et une haute précision.

En plus des industries des batteries et de la chimie, les machines à rouleaux à batterie (ou machines à rouleaux pour la fabrication de sable) conviennent également au concassage dans des industries telles que les mines, le ciment, les autoroutes, les chemins de fer, le charbon, la métallurgie et les matériaux de construction. Il peut broyer divers matériaux en pierre avec une résistance à la compression inférieure à 160 mégapascals, tels que les galets de rivière, la calcite, le quartz, le marbre, les galets, la bentonite, le minerai de fer, la pierre bleue, les pierres de montagne, les scories d'eau, le calcaire, le sable altéré, la diabase, le granit, le basalte. , etc.

Dans l'ensemble, la gamme d'applications des machines à rouleaux à batterie est large et ne se limite pas à l'industrie des batteries, mais comprend également plusieurs industries telles que la chimie, les mines, le ciment, les autoroutes, les chemins de fer, le charbon, la métallurgie, les matériaux de construction, etc.
