Roller-Press Apparatus

摘要

The present disclosure provides a roller-press apparatus, which comprises: an unwinding mechanism around which an electrode plate to be rolled is wound, the electrode plate has a foil and a coating layer, the foil has at least a coated area and a blank foil area, the foil is provided with the coating layer at the coated area and is not provided with the coating layer at the blank foil area; a rolling mechanism; and a stretching mechanism. The stretching mechanism comprises: two guide rollers; and an uneven roller positioned between the two guide rollers, and forming a wrap angle with the two guide rollers, the uneven roller matches the electrode plate in size to allow a protruding portion of the uneven roller to act on the foil at the blank foil area, so as to allow the foil at the blank foil area to be plastically deformed.

主权项

1. A roller-press apparatus, comprising:
an unwinding mechanism (1) around which an electrode plate (9) to be rolled is wound, and the unwinding mechanism (1) unwinding the electrode plate (9) to be rolled, the electrode plate (9) to be rolled having a foil (91) and a coating layer (92) provided on at least a surface of the foil (91), the foil (91) having at least a coated area (911) extending along a longitudinal direction of the foil (91) and a blank foil area positioned at a side direction of the coated area (911) on the corresponding surface provided with the coating layer (92), the foil (91) being provided with the coating layer (92) at the coated area (911) and being not provided with the coating layer (92) at the blank foil area; a rolling mechanism (2) comprising a press roller (21) and a back roller (22) which are oppositely provided, and used for rolling the electrode plate (9); a winding mechanism (3) winding the electrode plate (9) after rolled; and a stretching mechanism (5) provided between the rolling mechanism (2) and the winding mechanism (3), and comprising:
two guide rollers (51); andan uneven roller (52) positioned between the two guide rollers (51), and forming a wrap angle (E) with the two guide rollers (51), the uneven roller (52) matching the electrode plate (9) in size to allow a protruding portion (521) of the uneven roller (52) to act on the foil (91) at the blank foil area, so as to allow the foil (91) at the blank foil area to be plastically deformed.
