Abstract
The utility model discloses a dust collection head for reshaping a battery roll core, which is characterized by comprising a dust collection head (1), a reshaping roller (2), a reshaping roller mounting block (3) and a reshaping head mounting plate (4), wherein the reshaping roller (2) is mounted on the reshaping head mounting plate (4) through the reshaping roller mounting block (3) and is uniformly distributed; dust absorption head (1) is installed on plastic first mounting panel (4) to evenly arrange, occupy the clearance between shaping roller (2), dust absorption head (1) contains dust absorption head oral area (11) and dust absorption head lateral surface (12), dust absorption head oral area (11) are to the turn-ups, have covered the shared space of the battery roll core except that the plastic roller. The utility model discloses with the first mouth of a river portion of dust absorption to flanging, covered the shared all spaces of battery roll core except plastic roller, the cuttings that produce when rolling up the core plastic with the battery all fall into in the dust absorption head and are siphoned away, can not remain on battery roll core or scatter on equipment.
Description
Technical Field
The utility model relates to a dust absorption head of battery roll core plastic belongs to battery technical field.
Background
The diameter of the cylindrical battery is increased from 18mm to 21mm, 32mm or even 46mm, the battery capacity is also increased continuously, single-pole lugs or multi-pole lugs cannot meet the flow guiding requirement of charging and discharging of a large-capacity battery, and the large cylindrical battery with the end face welded by the full-pole lug winding core is produced in order to improve the energy density and the flow guiding capacity of the large cylindrical battery. With the advent of tesla 4680 batteries, large cylindrical batteries were favored by more battery manufacturers. The end face welding of the full-lug winding core is to mechanically shape the positive and negative electrode foils which are not coated with active materials at two ends of the battery winding core and then weld the positive and negative current collecting discs on the positive and negative winding cores of the winding core, so that the current-guiding capacity of the battery is improved. In the mechanical shaping process, metal dust can be generated due to extrusion friction between the shaping head and the foil, and the metal dust falls into the winding core to cause short circuit of the battery, so that the metal dust generated in the shaping process needs to be sucked away in time. The shaping head in the prior patent is not provided with a dust suction head, or the dust suction head is small, so that metal dust generated during shaping can not be completely removed, for example, in Chinese patents of CN114824426A, CN214176096U and CN215377 478U, no dust suction device is provided; in chinese patents CN114669631A and CN1121 33952A, although there are dust suction devices, the dust suction head is small and cannot suck all the metal dust generated in the shaping process.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned defect, a dust absorption head of battery roll core plastic is proposed.
The technical scheme of the utility model: the opening of the dust collection head is turned outwards to cover the space occupied by the battery winding core except for the shaping roller, so that all the dust generated during shaping of the battery winding core falls into the dust collection head to be absorbed, and the dust cannot remain in the battery winding core or scatter on equipment.
The opening of the dust collection head is 0.1 to 5mm lower than the shaping roll surface, and the gap between the outer side surface of the dust collection head and the shaping roll surface is 0.1 to 5mm.
The utility model has the following technical effects and advantages: the mouth of the dust collection head is flanged outwards to cover the space occupied by the battery winding core except the shaping roller, and all the dust generated during shaping the battery winding core falls into the dust collection head to be absorbed, so that the dust cannot remain in the battery winding core or scatter on equipment.
Drawings
Fig. 1 is an assembly view of the dust suction head of the present invention on the shaping head.
Fig. 2 is a single shape view of the dust suction head of the present invention.
In the figure: 1-a dust suction head; 2-shaping rollers; 3-a shaping roller mounting block; 4-a shaping head mounting plate; 11-the mouth of the cleaning head; 12-the outer side of the cleaning head.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Example 1: in the figure, 1 is a dust collection head, 2 is a shaping roller, 3 is a shaping roller mounting block, 4 is a shaping head mounting plate, 11 is a dust collection head opening part, and 12 is a dust collection head outer side surface. The shaping rollers 2 are arranged on the shaping head mounting plate 4 through the shaping roller mounting blocks 3 and are uniformly distributed; the dust collection head 1 is arranged on the shaping head mounting plate 4 and is uniformly distributed to fill the gap between the shaping rollers 2, the opening part 11 of the dust collection head is 0.5mm lower than the surface of the shaping roller, and the gap between the outer side surface 12 of the dust collection head and the surface of the shaping roller is 0.2mm.
The utility model provides a dust absorption head of core plastic is rolled up to battery for dust absorption when big cylinder lithium ion battery rolls up the core plastic adopts 3 toper shaping rollers, and evenly distributed presses the shape preparation dust absorption head of interval between the shaping roller, installs on the first mounting panel of plastic.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
