Description

Technical Field

[0001] The invention relates to the technical field of film making machines, and in particular to a dry electrode continuous film making machine. Background Art

[0002] The dry electrode continuous film making machine is an innovative device in the field of battery electrode manufacturing, which aims to break through the limitations of the traditional wet electrode preparation process. The traditional wet process requires a large amount of organic solvents, which has problems such as high cost, environmental pollution and safety hazards. The dry electrode continuous film making machine adopts a new solvent-free process to achieve continuous production of electrode membranes, providing a more efficient and environmentally friendly solution for the battery manufacturing industry.

[0003] It is known that China's public authorized patent CN221977976U discloses a dry electrode electrode film preparation device and electrode film preparation system, the electrode film preparation device includes a differential film-making roller system and a membrane thinning roller system arranged in sequence; the differential film-making roller system includes a first pressing roller, a second pressing roller and a third pressing roller arranged in sequence, the first pressing roller, the second pressing roller and the third pressing roller have different roller speeds, and a feed port is formed above the first pressing roller and the second pressing roller, the first pressing roller, the second pressing roller and the third pressing roller can hot press the powder put into the feed port into a continuous membrane; the membrane thinning roller system includes at least one pair of rollers arranged downstream of the third pressing roller, and the pair of rollers is used to perform thickness thinning on the continuous membrane to form a pole film for compounding with the pole piece. The dry electrode electrode film preparation device described in the utility model can improve the fiberization degree and structural strength of the membrane, which is conducive to ensuring the quality and consistency of the finished product of the pole film.

[0004] However, in the implementation of the relevant technology, it is found that the above-mentioned dry electrode continuous film making machine has the following problems:

[0005] During use, when the material passes through the gap between the rollers, under the action of pressure, the particles in the material are further approached and compacted, and the density of the film gradually increases. As the rollers continue to rotate, the material is continuously processed under the action of roller pressure to achieve continuous forming. If the upstream raw material preparation link fails to supply raw materials on time and in quality, or the downstream subsequent electrode processing steps cannot receive the prepared film in time, the waiting time of the film making machine will increase. For example, if the upstream mixing step cannot guarantee stable mixing quality and supply speed, the film making machine may frequently stop due to waiting for qualified raw materials, resulting in low production efficiency. Summary of the invention

[0014] Through the above technical scheme, the powdered material is added into the powder feeding mechanism one and the powder feeding mechanism two through the feeding port. At this time, the powder feeding mechanism one and the powder feeding mechanism two will both start to operate. At this time, the powdered material is located on the conveyor belt, and the conveyor belt transports the powdered material forward. At this time, the scraper plate will scrape the powdered material to make the thickness of the powdered material uniform during the transportation process. At this time, the powdered material evenly flows into the powder roller film forming mechanism one and the powder roller film forming mechanism two.

[0015] Preferably, a roller pressing motor is fixedly connected to the back side of the coating roller pressing mechanism, a steel roller is fixedly connected to the driving end of the roller pressing motor, and a heating tube is fixedly connected through one end of the steel roller.

[0016] Through the above technical solution, by starting the roller pressing motor 1, the roller pressing motor 1 drives the steel roller to operate, so that the membrane and the current collector substrate are pressed together to form a pole piece material for battery cell production.

[0017] Preferably, a gap adjustment table is fixedly connected to one side of the coating roller pressing mechanism, and a gap adjustment motor is fixedly installed at the bottom of the coating roller pressing mechanism.

[0027] The working principle and beneficial effects of the present invention are:

[0028] During use, the staff adds the powdered material into the powder feeding mechanism 1 and the powder feeding mechanism 2 through the feeding port. At this time, the powder feeding mechanism 1 and the powder feeding mechanism 2 will both start running. At this time, the powdered material is on the conveyor belt, and the conveyor belt transports the powdered material forward. At this time, the scraper plate will scrape the powdered material to make the thickness of the powdered material uniform during the transportation process. At this time, the powdered material flows evenly into the powder roller film forming mechanism 1 and the powder roller film forming mechanism 2. At the same time, the roller motor 2 drives the steel roller to operate, and the heating tube 2 will emit heat to act on the steel roller. At this time, the powdered material is formed into a film after passing through the steel roller and attached to the traction belt body for secondary roller forming. When the powdered material is formed and reaches the top of the third steel roll, the film is torn manually to separate the film from the traction belt. At the same time, the film enters between the slitting mechanism one and the slitting mechanism two. At this time, the micrometer two adjusts the gap between the cutter and the steel roll, and the cutter cuts the two sides of the film neatly. Then the film is manually pulled to the film coating rolling mechanism and rolled with the current collector substrate to make the film and the current collector substrate pressed together to form a pole piece material for battery cell production. Then the winding and correction mechanism winds up the film. This film making method avoids the failure to supply raw materials on time and in quality in the raw material preparation link, or the inability to receive the prepared film in time, avoids the waiting time and frequent shutdown of film making, and thus improves production efficiency.
