The specific embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
Fig. 2 carries out the structural representation that battery pole piece applies for a kind of coating battery pole piece machine of material loading hopper bottom generation accumulation that prevents that the utility model provides.
Referring to Fig. 2; The utility model provides a kind of material loading hopper bottom that prevents to produce the coating battery pole piece machine of accumulation; Include comma formula COMMA roller 1, discharge roller (C roller) 2 and foil conveying roller (B roller) 7 that vertical equity is placed; Said comma formula roller 1, discharge roller 2 and foil conveying roller 7 can freely be rotated in vertical direction; On concrete the realization, said comma formula roller 1, discharge roller 2 and foil conveying roller 7 are connected with motor or cylinder on the battery pole piece coating machine, are rotated by motor or air cylinder driven.
In the utility model, said discharge roller 2 be positioned at said comma formula roller 1 under, the left side of said comma formula roller 1 and discharge roller 2 is provided with a material loading hopper 4, said material loading hopper 4 is connected with gap between said comma formula roller 1 and the discharge roller 2.Be placed with the slurry that is used to apply the battery pole piece foil in the said material loading hopper 4.
In the utility model, below, the right side of said discharge roller 2 is set with a scraper 3, is used to wipe off the slurry of said discharge roller 2 outer surfaces.
In the utility model, said foil conveying roller 7 is positioned at the positive right side of said discharge roller 2, and said foil conveying roller 7 outer surfaces are wound with battery pole piece foil 10, and this battery pole piece foil 10 through oven dry, finally forms battery pole piece after applying slurry.
Referring to Fig. 2, the bottom of said material loading hopper 4 is provided with support 5, and said support 5 bottoms are connected with anchor clamps 50, and the right part of said anchor clamps 50 is provided with a contact 6, and said contact 6 contacts with the outer surface of said discharge roller 2.
Need to prove; Outer surface through the said discharge roller 2 of these contact 6 contacts; Can further not clean scraping clean slurry with scraper 3 on said discharge roller 2 outer surfaces, accumulate on the contact 6, regularly remove by the operator and get final product; Prevented not scrape clean slurry effectively and formed accumulation, guaranteed the quality of production of battery pole piece in the bottom of material loading hopper 4.
On concrete the realization; Said support 5 is hinged with the bottom of said material loading hopper 4; Thereby make support 5 can regulate the stroke on the left and right directions; Thereby the utility model further can be adjusted the amount of contact of contact 6 and said discharge roller 2 outer surfaces, guarantees the removing effect of 6 pairs of said discharge roller 2 outer surface slurries of contact, avoids because the wearing and tearing of contact 6 parts influence slurry removing effect.
