Abstract
The utility model relates to a blade mechanism for electrode roller compaction machine of lithium ion battery, which is characterized in that: slide rails are set on the relative support side wall of a milling roller, and are located at the position between 45 degree to 50 degree of the lower semicircular part of the milling roller, and are set along the direction which opposites to the normal running direction of the milling roller. A clip blade bracket for setting the blade is slide coupling to the slide rail. The utility model mainly employs the slide clip blade bracket to install the elastic blade onto the milling roller, and employs the blade to remove the electrode particles adhering to the milling roller so as to avoid the electrode particles disturbing the electrodes that have not been milled. The elastic deformation of the blade can complement the vertical displacement variety of the milling roller during the milling process. The utility model has simple structure and is easy for operation and maintenance, and has high clean efficiency, can effectively guarantee the production quality, and can be widely applied to the milling production of the aqueous solvent cathode system of the lithium ion battery, especially suitable for the massive and continuous electrode milling production.
Description
Technical field
The utility model relates to a kind of lithium ion cell electrode rolling device, is used for lithium ion cell electrode roller scraper mechanism in particularly a kind of aqueous solvent system.
Background technology
At present, the lithium ion battery negative of aqueous solvent system has at home and abroad begun to be extensive use of, and the aqueous solvent system is the later a kind of novel bonding system of electrode of PVdF system in succession.It makes water as solvent, has avoided the use of organic solvents such as NMP in process of production, can reduce cost greatly on the one hand, can avoid the pollution to environment on the other hand, is the first-elected in the world at present bonding system of electrode.It is little that but the aqueous solvent electrode system also exists adhesive strength, utmost point powder is with defectives such as adhesive force between the collector are not strong, therefore occur falling material in process of production easily for the aqueous solvent electrode system and roll the problem of roll banding, particularly produce for large tracts of land continuous type, roll roll banding and just become even more serious and outstanding, will directly influence the quality that lithium ion battery negative is produced.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of lithium ion cell electrode roller scraper mechanism that is used for simple in structure, easy to use is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of lithium ion cell electrode roller scraper mechanism that is used for, it is characterized in that correspondence is provided with slideway on the supporting side walls of milling roller, slideway and is on the contrary direction of milling roller normal operation direction between 45 °～50 ° of milling roller lower half circle; Slideway is provided with the intermediate plate knife rest that is slidingly matched with it, and blade is arranged in the intermediate plate knife rest.
The described soft stainless steel blade thickness that is provided with is 0.1mm～0.25mm.
Described knife-blade is apart from intermediate plate knife rest edge 8mm～15mm.
Described doctor blade is bent downwardly curved, and angle of bend is 25 °～50 °.
The utility model beneficial effect is: by adopting the slidingtype knife rest whippy scraper is assembled on the milling roller, the electrode particle that utilizes scraper edge will stick on the milling roller is removed, and avoids sticking to the electrode that the electrode particle influence on the milling roller does not roll; And the elastic deformation that utilizes doctor blade itself compensates the change in displacement that milling roller moves up and down in the process of rolling, to adapt to the diverse location of milling roller, keep blade closely to contact, produce tangential scraping power, thereby it is cleaner quick to carry out the milling roller cleaning on the milling roller surface with milling roller.Generally be applicable to the cathode pole piece that rolls lithium ion battery aqueous solvent system continuously, improve situations such as pole piece that pole piece causes owing to dry linting and roll banding is bad and discarded.This scraper elimination efficiency height simultaneously effectively guarantees the quality of product, and easy operating and maintenance, can carry out large tracts of land and produce and use, owing to adopted flexible bigger blade, so scraper is very little to the injury power that rolls axle surface itself.It is simple in structure, easy to use, be widely used.
Description of drawings
Fig. 1 is that the utility model is arranged at milling roller supporting side walls syndeton schematic diagram;
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of lithium ion cell electrode roller scraper mechanism that is used for, it is characterized in that correspondence is provided with slideway 3 on the supporting side walls 2 of milling roller 1, slideway 3 is between 45 °～50 ° at milling roller 1 lower half circle angle a, and is on the contrary direction of milling roller 1 normal operation direction; Slideway 3 is provided with the intermediate plate knife rest 4 that is slidingly matched with it, and blade 5 is arranged in the intermediate plate knife rest 4.
Described soft stainless steel blade 5 thickness that are provided with are 0.1mm～0.25mm; Edge of a knife angle can be 30 °～45 °.
Described blade 5 blades are apart from intermediate plate knife rest edge 8mm～15mm.
Described doctor blade 5 is bent downwardly curved, and angle of bend b is 25 °～50 °.
Blade is installed in the milling roller bottom, and knife-blade is pointed on the milling roller backwards rotation direction.Scraper is in place, and the normal roller that starts carries out shutting down after several weeks of zero load rotation after the scraper installation, checks whether scraper is shifted, if be not shifted, then begins the work that normally rolls, if be shifted, then rolls work again after the adjustment.Its production technology and production process need not be carried out other any change, but want the periodic cleaning doctor blade, if damaged replacing is in time arranged, guarantee to produce the high-quality and efficient of product.
With lithium ion battery 053048 aqueous solvent system negative pole is example, dry linting and roll banding situation when not adopting this scraper system to produce to roll on the pole piece are more serious, the fraction defective of electrode reaches more than 70%, can't produce continuously basically, and the pole piece surface appearance is very poor.Install after this scraper that bonding electrode particle can in time be cleaned out on the milling roller, though the electrode particle that has minority is with the bonding situation of milling roller, but timely cleaning by doctor blade, follow-up pole piece do not rolled can bring influence, therefore significantly improve the rolling effect of pole piece, improved the yields of pole piece simultaneously.After adopting scraper to produce, aqueous solvent system negative pole can be produced continuously, and the defective products rate can be controlled in below 2%, and the pole piece surface appearance is greatly improved, and effectively reduces production cost.Adopt slide block type feed motion structure, both can guarantee that scraper edge can also help the loading and unloading and the maintenance of whole knife rest simultaneously comprehensively with the milling roller contact with the parallel blade that makes of milling roller axis; Utilize the elastic deformation campaign and the wear-compensating of scraper itself, carry out the milling roller cleaning thereby be beneficial in the tangential scraping power of milling roller surface generation simultaneously.
Above-mentioned with reference to embodiment to being used for the detailed description that lithium ion cell electrode roller scraper mechanism is carried out; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
